NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
 
1.    BASIS OF PRESENTATION
 
The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to such rules and regulations. These interim condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto filed by Coherent, Inc. on Form 10-K for the fiscal year ended September 28, 2019. In the opinion of management, all adjustments necessary for a fair presentation of financial condition and results of operation as of and for the periods presented have been made and include only normal recurring adjustments. Interim results of operations are not necessarily indicative of results to be expected for the year or any other interim periods. Our fiscal year ends on the Saturday closest to September 30 and our third fiscal quarter includes 13 weeks of operations in each fiscal year presented. Fiscal 2020 includes 53 weeks and fiscal 2019 includes 52 weeks.

The consolidated financial statements include the accounts of Coherent, Inc. and its direct and indirect subsidiaries (collectively, the "Company", "we", "our", "us" or "Coherent"). Intercompany balances and transactions have been eliminated.

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

The COVID-19 pandemic has significantly increased economic uncertainty and decreased demand for our products in many markets we serve, which could continue for an unknown period of time. In these circumstances, there may be developments outside of our control, including the length and extent of the COVID-19 outbreak, government-imposed measures and our ability to ship products and/or service installed products that may require us to adjust our operating plans. As such, given the dynamic nature of this situation, we cannot predict the future impacts of COVID-19 on our financial condition, results of operations or cash flows. However, we do expect that it will have an adverse impact on our revenue as well as our overall profitability and may lead to an increase in inventory provisions, allowances for credit losses, and a volatile effective tax rate driven by changes in the mix of earnings across our markets.

Based on our internal projections and the preparation of our financial statements for the quarter ended April 4, 2020, and considering the forecasted decrease in demand due to the COVID-19 pandemic and other factors, we believed that the fair value of our Industrial Lasers & Systems ("ILS") reporting unit might no longer have exceeded its carrying value and performed an interim goodwill impairment test on the ILS and OEM Laser Sources ("OLS") reporting units. Based on the estimated fair value of the ILS reporting unit, we recorded non-cash pre-tax goodwill impairment charges of $327.2 million in the quarter ended April 4, 2020. In addition, we performed impairment tests on the long-lived assets allocated to the asset group of the ILS reporting unit, including intangible assets, property, plant and equipment and ROU assets as of April 4, 2020 and recorded non-cash pre-tax charges in the quarter ended April 4, 2020 related to the impairment of intangible assets, property, plant and equipment and ROU assets of the ILS reporting unit of $33.9 million, $85.6 million and $1.8 million, respectively. See Note 8, "Goodwill and Intangible Assets" and Note 11, "Leases" in the Notes to Condensed Consolidated Financial Statements.

Change in Accounting Policies - Leasing

Except for the adoption of Accounting Standards Update ("ASU") 2016-02, Leases ("ASC 842") on September 29, 2019 and the resulting changes in our accounting policies and disclosures for lease accounting, there have been no significant changes to our significant accounting policies as of and for the nine months ended July 4, 2020, as compared to the significant accounting policies described in our Annual Report on Form 10-K for our fiscal year ended September 28, 2019.

Effective September 29, 2019, we adopted ASC 842, using the optional transition method, by which companies may elect not to recast the comparative periods presented in financial statements in the period of adoption and recognize a cumulative effect adjustment in the period of adoption. See Note 2, "Recent Accounting Standards" to the Notes to Condensed
10

Consolidated Financial Statements regarding the impact of adoption.

We determine if an arrangement is a lease at inception for arrangements with an initial term of more than 12 months, and classify it as either finance or operating.

Finance leases are generally those that allow us to substantially utilize or pay for the entire asset over its estimated useful life. Finance leases are recorded in other assets and finance lease liabilities within other current and other long-term liabilities on our condensed consolidated balance sheets. Finance lease assets are amortized in operating expenses on a straight-line basis over the shorter of the estimated useful lives of the assets or the lease term, with the interest component included in interest expense and recognized using the effective interest method over the lease term.

Operating leases are recorded in other assets and operating lease liabilities within other current and other long-term liabilities on our condensed consolidated balance sheets. For operating leases of buildings, we account for non-lease components, such as common area maintenance, as a component of the lease, and include it in the initial measurement of our operating lease assets and corresponding liabilities. Operating lease assets are amortized on a straight-line basis in operating expenses over the lease term. Our lease liabilities are recognized based on the present value of the remaining fixed lease payments, over the lease term, using a discount rate of similarly secured borrowings available to us. Most of our leases do not provide an implicit rate. We use our incremental borrowing rate for the same jurisdiction and term as the associated lease based on the information available at the lease commencement date to determine the present value of the lease payments. We used the incremental borrowing rate as of September 28, 2019 for operating leases that commenced prior to that date. For the purpose of lease liability measurement, we consider only payments that are fixed and determinable at the time of commencement. Any variable payments that depend on an index or rate are expensed as incurred. Our lease terms may include options to extend when it is reasonably certain that we will exercise that option. Our lease assets also include any lease payments made and exclude any lease incentives received prior to commencement. Our lease assets are tested for impairment in the same manner as long-lived assets used in operations. We generally recognize sublease income on a straight-line basis over the sublease term.


2.    RECENT ACCOUNTING STANDARDS

Adoption of New Accounting Pronouncement

In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, Simplifying the Accounting for Income Taxes. The ASU updates specific areas of ASC 740, Income Taxes, to reduce complexity while maintaining or improving the usefulness of the information provided to users of financial statements. We elected to early adopt ASU 2019-12 in the second quarter of fiscal 2020 with no material impact to our condensed consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The guidance allows companies to reclassify stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act of 2017 (the "Tax Act") from accumulated other comprehensive income to retained earnings. The guidance also requires certain new disclosures regardless of the election. The amendments in ASU 2018-02 are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. We adopted ASU 2018-02 in the first quarter of fiscal 2020 with no material impact to our condensed consolidated financial statements.

In February 2016, the FASB issued accounting guidance (ASC 842) that modifies lease accounting for lessees to increase transparency and comparability by recording lease assets and liabilities for operating leases and disclosing key information about leasing arrangements. We adopted ASC 842 in the first quarter of fiscal 2020 utilizing the optional transition method by applying the new standard to leases existing at the date of initial application and not restating comparative periods. We determine if an arrangement contains a lease at inception for arrangements with an initial term of more than 12 months, and classify it as either finance or operating. We have elected the package of practical expedients which allows us to not reassess 1) whether any expired or existing contracts are or contain leases; 2) the lease classification for any expired or existing leases; and 3) initial direct costs for any existing leases. In addition, we also elected to use the practical expedient allowed in the standard to not separate lease and non-lease components and apply the short-term lease measurement and recognition exemption to all leases shorter than 12 months when calculating the lease liability under ASC 842. The adoption of the standard resulted in the recognition of operating lease assets of $90.4 million, with corresponding operating lease liabilities of $93.5 million on our condensed consolidated balance sheet, primarily related to real estate leases. The difference between the operating lease right-of-use assets and operating lease liabilities primarily represents our deferred
11

rent as of adoption. As of the date of adoption, we recognized finance lease assets of $1.0 million, with corresponding finance lease liabilities of $0.9 million on our condensed consolidated balance sheet, primarily related to equipment leases.

See Note 11, "Leases" for more information.

Recently Issued Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and a subsequent amendment, ASU 2018-19 (collectively, Topic 326). Topic 326 requires measurement and recognition of expected credit losses for financial assets held. The new standard will become effective for our fiscal year 2021, which begins on October 4, 2020. We are currently evaluating the impact of our pending adoption of Topic 326 on our consolidated financial statements. We currently expect that the standard will not have a material impact on our consolidated statements of operations.


3.  REVENUE RECOGNITION
Disaggregation of Revenue

Based on the information that our chief operating decision maker ("CODM") uses to manage the business, we disaggregate revenue by type and market application within each segment. No other level of disaggregation is required considering the type of products, customers, markets, contracts, duration of contracts, timing of transfer of control and sales channels.

The following tables summarize revenue from contracts with customers (in thousands):

Contract Balances

We record accounts receivable when we have an unconditional right to the consideration. Contract liabilities are recorded when cash payments are received or due in advance of performance. Contract liabilities consist of customer deposits and deferred revenue, where we have unsatisfied or partly satisfied performance obligations. Contract liabilities classified as customer deposits are included in other current liabilities and contract liabilities classified as deferred revenue are included in other current liabilities or other long-term liabilities on our condensed consolidated balance sheets. Payment terms vary by customer.

A rollforward of our customer deposits and deferred revenue is as follows (in thousands):
Beginning balance, September 28, 2019 (1)
$ 42,550   
Additions to customer deposits and deferred revenue 137,747

4.  BUSINESS COMBINATIONS
Fiscal 2019 Acquisitions
Ondax
On October 5, 2018, we acquired privately held Ondax for approximately $12.0 million, excluding transaction costs. Ondax developed and produced photonic components which are used on an OEM basis by the laser industry as well as incorporated into its own stabilized lasers and Raman Spectroscopy systems. Ondax’s operating results have been included in our Industrial Lasers & Systems segment. See Note 19, "Segment and Geographic Information."
Our allocation of the purchase price is as follows (in thousands):
Tangible assets:
  Cash $ 103   
  Accounts receivable 534   
  Inventories 1,793   
  Prepaid expenses and other assets 17   
  Deferred tax assets 681   
  Property and equipment 122   
  Liabilities assumed (499)  
Intangible assets:
  Existing technology 5,600   
  Customer relationships 300   
Goodwill 3,333   
Total $ 11,984   
Results of operations for the business have been included in our condensed consolidated financial statements subsequent to the date of acquisition and pro forma results of operations in accordance with authoritative guidance for prior periods have not been presented because the effect of the acquisition was not material to our prior period consolidated financial results.
The identifiable intangible assets are being amortized over their respective useful lives of 1 to 8 years. The fair values of the acquired intangibles were determined using the income approach. In performing these valuations, the key underlying probability-adjusted assumptions of the discounted cash flows were projected revenues, gross margin expectations and operating cost estimates. The valuations were based on the information that was available as of the acquisition date and the expectations and assumptions that have been deemed reasonable by our management. There are inherent uncertainties and management judgment required in these determinations. This acquisition resulted in a purchase price that exceeded the estimated fair value of tangible and intangible assets, which was allocated to goodwill. In the quarter ended April 4, 2020, we performed an interim impairment test and the entire goodwill balance and a portion of the existing technology intangible assets were impaired. See Note 8, "Goodwill and Intangible Assets".
We believe the amount of goodwill relative to identifiable intangible assets relates to several factors including: (1) potential buyer-specific synergies related to the development of new technologies; and (2) the potential to leverage our sales force to attract new customers.
None of the goodwill from this purchase is deductible for tax purposes.

Quantum
On October 5, 2018, we acquired certain assets of Quantum Coating, Inc. ("Quantum") for approximately $7.0 million, excluding transaction costs, and accounted for the transaction as an asset purchase.
Our allocation of the purchase price is as follows (in thousands):
Tangible assets:
  Property and equipment $ 2,770   
Intangible assets:
  Existing technology 1,600   
  Customer relationships 230   
  Production know-how 2,300   
  Backlog 100   
Total $ 7,000   
The identifiable intangible assets are being amortized over their respective useful lives of 1 to 5 years. The fair values of the acquired intangibles were determined using the income approach. In performing these valuations, the key underlying probability-adjusted assumptions of the discounted cash flows were projected revenues, gross margin expectations and operating cost estimates. The valuations were based on the information that was available as of the acquisition date and the expectations and assumptions that have been deemed reasonable by our management. There are inherent uncertainties and management judgment required in these determinations.

5.    FAIR VALUES
 
We have not changed our valuation techniques in measuring the fair value of any financial assets and liabilities during the period. We recognize transfers between levels within the fair value hierarchy, if any, at the end of each quarter. There were no transfers between levels during the periods presented. As of July 4, 2020 and September 28, 2019, we had one investment carried on a cost basis. See Note 9, "Balance Sheet Details." If we were to fair value this investment, it would be based upon Level 3 inputs. This investment is not considered material to our condensed consolidated financial statements.

We measure the fair value of outstanding debt obligations for disclosure purposes on a recurring basis. As of July 4, 2020, the current and long-term portion of long-term obligations of $6.6 million and $397.3 million, respectively, are reported at amortized cost. As of September 28, 2019, the current and long-term portion of long-term obligations of $4.9 million and $392.2 million, respectively, are reported at amortized cost. These outstanding obligations are classified as Level 2 as they are not actively traded and are valued using a discounted cash flow model that uses observable market inputs. Based on the discounted cash flow model, the fair value of the outstanding debt approximates amortized cost.

 ___________________________________________________
(1) Valuations are based upon quoted market prices in active markets involving similar assets. The market inputs used to value these instruments generally consist of market yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. Pricing sources include industry standard data providers, security master files from large financial institutions, and other third party sources which are input into a distribution-curve-based algorithm to determine a daily market value. This creates a "consensus price" or a weighted average price for each security.

(2) The principal market in which we execute our foreign currency contracts is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants usually are large commercial banks. Our foreign currency contracts’ valuation inputs are based on quoted prices and quoted pricing intervals from public data sources and do not involve management judgment. See Note 7, "Derivative Instruments and Hedging Activities."

(3) The fair value of mutual funds is determined based on quoted market prices. Securities traded on a national exchange are stated at the last reported sales price on the day of valuation; other securities traded in over-the-counter markets and listed securities for which no sale was reported on that date are stated as the last quoted bid price.  


6.              SHORT-TERM INVESTMENTS
 
We consider all highly liquid investments with maturities of three months or less at the time of purchase to be cash equivalents. Investments classified as available-for-sale are reported at fair value with unrealized gains and losses, net of related income taxes, recorded as a separate component of other comprehensive income ("OCI") in stockholders’ equity until realized. Interest and amortization of premiums and discounts for debt securities are included in interest income. Gains and losses on securities sold are determined based on the specific identification method and are included in other income (expense).

7.    DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
 
We maintain operations in various countries outside of the United States and have foreign subsidiaries that manufacture and sell our products in various global markets. The majority of our sales are transacted in U.S. dollars. However, we do generate revenues in other currencies, primarily the Euro, Japanese Yen, South Korean Won, Singapore Dollar and Chinese Renminbi (RMB). As a result, our earnings, cash flows and cash balances are exposed to fluctuations in foreign currency exchange rates. We attempt to limit these exposures through financial market instruments. We utilize derivative instruments, primarily forward contracts with maturities of two months or less, to manage our exposure associated with anticipated cash flows and net asset and liability positions denominated in foreign currencies. Gains and losses on the forward contracts are mitigated by gains and losses on the underlying instruments. We do not use derivative financial instruments for speculative or trading purposes. The credit risk amounts represent our gross exposure to potential accounting loss on derivative instruments that are outstanding or unsettled if all counterparties failed to perform according to the terms of the contract, based on then-current currency rates at each respective date.
 
Non-Designated Derivatives

  Sell $ (86,375)   $ (86,984)   $ (720)   $ (473)  

17

The fair value of our derivative instruments is included in prepaid expenses and other assets and in other current liabilities in our Condensed Consolidated Balance Sheets. See Note 5, "Fair Values."

During the three and nine months ended July 4, 2020, we recognized gains of $1.1 million and $1.2 million, respectively, in other income (expense) for derivative instruments not designated as hedging instruments. During the three and nine months ended June 29, 2019, we recognized gains of $0.9 million and losses of $5.8 million, respectively, in other income (expense) for derivative instruments not designated as hedging instruments.

Master Netting Arrangements

To mitigate credit risk in derivative transactions, we enter into master netting arrangements that allow each counterparty in the arrangements to net settle amounts of multiple and separate derivative transactions under certain conditions. We present the fair value of derivative assets and liabilities within our condensed consolidated balance sheet on a gross basis even when derivative transactions are subject to master netting arrangements and may otherwise qualify for net presentation. The impact of netting derivative assets and liabilities is not material to our financial position for any of the periods presented. Our derivative contracts do not contain any credit risk related contingent features and do not require collateral or other security to be furnished by us or the counterparties.


8.    GOODWILL AND INTANGIBLE ASSETS 

During the quarter ended July 4, 2020, we noted no indications of impairment or triggering events, not already considered in the quarter ended April 4, 2020, to cause us to review goodwill for potential impairment. We will conduct our annual goodwill testing during the fourth fiscal quarter.

In the quarter ended April 4, 2020, the worldwide spread of coronavirus ("COVID-19") created significant volatility, uncertainty and disruption to the global economy, representing an indicator to test our goodwill for impairment. Based on our internal projections and the preparation of our financial statements for the quarter ended April 4, 2020, and considering the forecasted decrease in demand due to the COVID-19 pandemic and other factors, we believed that the fair value of our ILS reporting unit might no longer have exceeded its carrying value and performed an interim goodwill impairment test on the ILS reporting unit. We also performed an interim goodwill impairment test on the OLS reporting unit.

Our goodwill impairment tests for the ILS and OLS reporting units were performed by comparing the fair value of the reporting units with their carrying values and recognizing an impairment charge for the amount by which the carrying value exceeded the fair value. Based on the estimated fair value of the ILS reporting unit, in the quarter ended April 4, 2020, we recorded a non-cash pre-tax charge related to the ILS reporting unit of $327.2 million, reducing the goodwill balance of the reporting unit to zero. The impairment charge was primarily the result of a decline in projected cash flows of the ILS reporting unit driven by lower forecasted sales volumes and profitability in several business units. The impairment charge was also the result of changes in certain market-related inputs to the analysis to reflect macro-economic changes caused by the impact of COVID-19, including lower pricing multiples for comparable public companies. No impairment charge was recognized for the OLS reporting unit as the fair value significantly exceeded the carrying value of the reporting unit.

In assessing goodwill for impairment, we were required to make significant judgments related to the fair value of our reporting units. We used a combination of the Income (discounted cash flow) approach and the Market (market comparable) approach to estimate the fair value of our reporting units. The Income approach utilizes the discounted cash flow model to provide an estimation of fair value based on the cash flows that a business expects to generate. These cash flows are based on forecasts developed internally by management which are then discounted at an after tax rate of return required by equity and debt market participants of a business enterprise. Our assumptions used in the forecasts are based on historical data, supplemented by current and anticipated market conditions, estimated growth rates and management’s plans. The rate of return on cost of capital is weighted based on the capitalization of comparable companies. We utilized a discount rate for each of our reporting units that represents the risks that our businesses face, considering their sizes, their current economic environment and other industry data as we believe is appropriate. The Market approach determines fair value by comparing the reporting units to comparable companies in similar lines of business that are publicly traded. The selection of comparable companies is based on the markets in which the reporting units operate giving consideration to risk profiles, size, geography and diversity of products and services. Total Enterprise Value (TEV) multiples such as TEV to revenues and TEV to earnings (if applicable) before interest and taxes of the publicly traded companies are calculated. We utilized multiples for each of our reporting units that represent the risks that our businesses face, considering their sizes, their current economic environment and other industry data as we believe is appropriate. The interim goodwill impairment
18

testing results were also reconciled with our market capitalization as of April 4, 2020, as the final step in the impairment testing.

Before performing the goodwill impairment test for the ILS reporting unit, we performed impairment tests on the long-lived assets allocated to the asset group of the ILS reporting unit, including intangible assets, property, plant and equipment and ROU assets as of April 4, 2020, due primarily to the same indicators that led to the interim goodwill impairment testing. Based on the impairment tests performed, we concluded that some of the long-lived assets allocated to the asset group of the ILS reporting unit were impaired as of April 4, 2020. Accordingly, we recorded non-cash pre-tax charges in the quarter ended April 4, 2020 related to the intangible assets, property, plant and equipment and right-of-use ("ROU") assets of the ILS reporting unit of $33.9 million, $85.6 million and $1.8 million, respectively. We did not identify any indicators that would lead us to believe that the carrying value of the long-lived assets allocated to the asset group of the OLS reporting unit may not be recoverable as of April 4, 2020.

In assessing our long-lived assets for impairment, we were required to make significant judgments related to the fair value of our long-lived assets, which are comprised of personal property, real property, and intangible assets. We used a combination of the Income, the Market approach, and the Cost (cost to create) approach to estimate the fair value of our long-lived assets. Our personal property assets consist of laser manufacturing and assembly equipment, semiconductor tools, laboratory and test equipment, furniture and fixtures and computer hardware and software. We used the Cost Approach (with support from the Market Approach) to estimate the fair value of our personal property, taking into consideration the physical deterioration, functional obsolescence and economic obsolescence of our personal property assets. Our real property assets consist of land and buildings, land rights (ground leased) and ROU assets. In determining the fair value of our real property assets, we used a combination of the Income, Market (sales comparison) and Cost approaches. We considered historical transaction information, current market conditions, operating performance, forecast growth and market-derived rates of return in our real property determination of fair value. The fair value of our ROU assets was determined using the Income approach by considering off-market components of the associated ROU leases. Our intangible assets consist of technology and customer relationship assets, and we used the Income approach to estimate the fair value of our intangible assets. We identified cash flows associated with each intangible asset, which were discounted at an after-tax rate of return appropriate for the risk profile of each intangible asset.

For accounting purposes, when an intangible asset is fully amortized, it is removed from the disclosure schedule. The gross carrying amounts as of July 4, 2020, have been reduced by impairment charges of $27.7 million and $6.2 million for existing technology and customer relationships, respectively.

10.     BORROWINGS
 
On November 7, 2016 (the "Closing Date"), we entered into a Credit Agreement by and among us, Coherent Holding BV & Co. K.G. (formerly Coherent Holding GmbH), as borrower (the "Borrower"), and certain of our direct and indirect subsidiaries from time to time party thereto, as guarantors, the lenders from time to time party thereto, Barclays Bank PLC, as administrative agent and an L/C Issuer, Bank of America, N.A., as an L/C Issuer, and MUFG Union Bank, N.A., as an L/C Issuer (the "Initial Credit Agreement" and, as amended by the Amendments (defined below), the "Credit Agreement"). The Initial Credit Agreement provided for a 670.0 million Euro senior secured term loan facility (the "Euro Term Loan") and a $100.0 million senior secured revolving credit facility (the "Revolving Credit Facility") with a $30.0 million letter of credit sublimit and a $10.0 million swing line sublimit, in each case, which may be increased from time to time pursuant to an incremental feature set forth in the Credit Agreement. The Initial Credit Agreement was amended on May 8, 2017 (the "First Amendment") to reduce the interest rate margins applicable to the Euro Term Loan and was amended again on July
21

5, 2017 (the "Second Amendment" and, together with the First Amendment, the "Amendments") to make certain technical changes in connection with the conversion of the Borrower from a German company with limited liability to a German limited partnership.

The Credit Agreement contains customary mandatory prepayment provisions. The Borrower has the right to prepay loans under the Credit Agreement in whole or in part at any time without premium or penalty, subject to customary breakage costs. Revolving loans may be borrowed, repaid and reborrowed until the fifth anniversary of the Closing Date, at which time all outstanding revolving loans must be repaid. The Euro Term Loan matures on the seventh anniversary of the Closing Date, at which time all outstanding principal and accrued and unpaid interest on the Euro Term Loan must be repaid.

As of July 4, 2020, the outstanding principal amount of the Euro Term Loan was 359.9 million Euros. As of July 4, 2020, the outstanding amount of the Revolving Credit Facility was $10.0 million plus a 10.0 million Euro letter of credit.

Loans under the Credit Agreement bear interest, at the Borrower’s option, at a rate equal to either (i)(x) in the case of calculations with respect to U.S. Dollars or certain other alternative currencies, the London interbank offered rate (the "LIBOR") or (y) in the case of calculations with respect to the Euro, the euro interbank offered rate ("EURIBOR" and, together with LIBOR), the "Eurocurrency Rate") or (ii) a base rate (the "Base Rate") equal to the highest of (x) the federal funds rate, plus 0.50%, (y) the prime rate then in effect and (z) the Eurocurrency Rate for loans denominated in U.S. dollars applicable to a one-month interest period, plus 1.0%, in each case, plus an applicable margin that is subject to adjustment pursuant to a pricing grid based on consolidated total gross leverage ratio. At July 4, 2020, the applicable margin for Euro Term Loans borrowed as Eurocurrency Rate loans was 2.25% per annum and as Base Rate loans was 1.25%. The applicable margin for revolving loans borrowed as Eurocurrency Rate loans was 4.00% per annum and as Base Rate loans was 3.00% per annum. Interest on Base Rate Loans is payable quarterly in arrears. Interest on Eurocurrency Rate loans is payable at the end of the applicable interest period (or at three month intervals if the interest period exceeds three months).

The Credit Agreement requires the Borrower to make scheduled quarterly payments on the Euro Term Loan of 0.25% of the original principal amount of the Euro Term Loan, with any remaining principal payable at maturity. A commitment fee accrues on any unused portion of the revolving loan commitments under the Credit Agreement at a rate of 0.375% or 0.5% depending on the consolidated total gross leverage ratio at any time of determination. The Borrower is also obligated to pay other customary fees for a credit facility of this size and type.

On the Closing Date, we and certain of our direct and indirect subsidiaries, as guarantors, provided an unconditional guaranty of all obligations of the Borrower and the other loan parties arising under the Credit Agreement, the other loan documents and under swap contracts and treasury management agreements with the lenders or their affiliates (with certain limited exceptions). The Borrower and the guarantors have also granted security interests in substantially all of their assets to secure such obligations.

The Credit Agreement contains customary affirmative and negative covenants, including covenants limiting the ability of us and our subsidiaries to, among other things, incur debt, grant liens, make investments, make certain restricted payments, transact with affiliates, and sell assets. The Credit Agreement also requires us and our subsidiaries to maintain a senior secured net leverage ratio as of the last day of each fiscal quarter of less of than or equal to 3.50 to 1.00. We were in compliance with all covenants at July 4, 2020.

We incurred $28.5 million of debt issuance costs related to the Euro Term Loan and $0.5 million of debt issuance costs to the original lenders related to the First Amendment, which are included in short-term borrowings and current portion of long-term obligations and long-term obligations in the condensed consolidated balance sheets and will be amortized to interest expense over the seven year life of the Euro Term Loan using the effective interest method, adjusted to accelerate amortization related to voluntary repayments. We incurred $2.3 million of debt issuance costs in connection with the Revolving Credit Facility which were capitalized and included in prepaid expenses and other assets in the condensed consolidated balance sheets and will be amortized to interest expense using the straight-line method over the contractual term of five years of the Revolving Credit Facility.

Additional sources of cash available to us were international currency lines of credit and bank credit facilities totaling $16.4 million as of July 4, 2020, of which $13.5 million was unused and available. These unsecured international credit facilities were used in Europe and Japan during the first nine months of fiscal 2020. As of July 4, 2020, we had utilized $2.9 million of the international credit facilities as guarantees in Europe.

11.     LEASES

We determine if an arrangement contains a lease at inception for arrangements with an initial term of more than 12 months, and classify it as either a finance or operating lease. We lease certain real and personal property from unrelated third parties under non-cancellable operating leases that expire at various dates through fiscal 2032. These operating leases are mainly for administrative offices, research-and-development and manufacturing facilities, as well as sales offices in various countries around the world. Certain leases require us to pay property taxes, insurance and routine maintenance, and include escalation clauses. Many leases include one or more options to renew. We assume renewals in our determination of the lease term when the renewals are deemed to be reasonably assured at lease commencement. We have also entered into various finance leases to obtain servers and certain other equipment for our operations. These arrangements are typically for three to six years. Our assets, liabilities and lease costs related to finance leases are immaterial.

As the rates implicit in our leases are not readily determinable, we use incremental borrowing rates based on the information available at the commencement date in determining the present value of future lease payments. We consider both the credit rating and the length of the lease when calculating the incremental borrowing rate. We combine lease and non-lease components into a single lease component for both our operating and finance leases.

For the purpose of lease liability measurement, we consider only payments that are fixed and determinable at the time of commencement. Any variable payments that depend on an index or rate are expensed as incurred.

We generally recognize sublease income on a straight-line basis over the sublease term.

23

As a result of interim impairment testing performed on long-lived assets in the quarter ended April 4, 2020, we recorded non-cash pre-tax charges related to the ROU assets of the ILS reporting unit of $1.8 million in the quarter ended April 4, 2020. See Note 8, "Goodwill and Intangible Assets" for discussion of the interim impairment testing.

12.  STOCK-BASED COMPENSATION
 
Fair Value of Stock Compensation
 
We recognize compensation expense for all share-based payment awards based on the fair value of such awards. The expense is recognized on a straight-line basis per tranche over the respective requisite service period of the awards.
 
Determining Fair Value
 
The fair values of shares purchased under the Employee Stock Purchase Plan ("ESPP") for the three and nine months ended July 4, 2020 and June 29, 2019, respectively, were estimated using the following weighted-average assumptions:
Employee Stock Purchase Plan
Three Months Ended Nine Months Ended
July 4,
2020
June 29,
2019
July 4,
2020
June 29,
2019
Expected life in years 0.5 0.5 0.5 0.5
Volatility 63.7  % 47.9  % 53.0  % 47.9  %
Risk-free interest rate 0.54  % 2.46  % 1.27  % 2.43  %
Expected dividend yield —  % —  % —  % —  %
Weighted average fair value per share $ 43.35    $ 40.42    $ 43.81    $ 40.57   

We grant performance restricted stock units to officers and certain employees. The performance restricted stock unit agreements provide for the award of performance units with each unit representing the right to receive one share of our common stock to be issued after the applicable award vesting period. The final number of units awarded, if any, for these performance grants will be determined as of the vesting dates, based upon our total shareholder return over the performance period compared to the applicable Russell Index and could range from no units to a maximum of twice the initial award units.

The weighted average fair value for the performance units granted for the nine months ended July 4, 2020 and June 29, 2019 was determined using a Monte Carlo simulation model incorporating the following weighted average assumptions:
Nine Months Ended Nine Months Ended
July 4,
2020
June 29,
2019
Risk-free interest rate 0.9  % 2.9  %
Volatility 50.4  % 43.7  %
Weighted average fair value per share $ 162.14    $ 117.43   


25

We recognize the estimated cost of these awards, as determined under the simulation model, over the related service period of approximately 3 years, with no adjustment in future periods based upon the actual shareholder return over the performance period.

In addition, in the three months ended July 4, 2020, we issued performance units to certain employees with vesting based on goals related to free cash flow target amounts, with the initial fair value determined based on our closing stock price on the date of grant. Such awards were granted to serve as a performance incentive with a pay-for-performance forward-looking free cash flow target for the fiscal year in recognition of the impact of the COVID-19 pandemic. The number of shares issuable under these performance units upon satisfaction of the free cash flow performance criteria is capped at 100% of target. The total stock-based compensation of these awards will be adjusted based on the level of achievement of free cash flow.

Stock Compensation Expense
 
The following table shows total stock-based compensation expense and related tax benefits included in the condensed consolidated statements of operations for the three and nine months ended July 4, 2020 and June 29, 2019 (in thousands):

$ 12,834    $ 8,243    $ 27,662    $ 22,429   

During the three and nine months ended July 4, 2020, stock-based compensation expense includes $3.5 million related to acceleration of stock-based compensation as a result of our former CEO's transition from CEO to Special Advisor to the company as of April 6, 2020.

During the three and nine months ended July 4, 2020, $2.1 million and $4.3 million of stock-based compensation cost, respectively, were capitalized as part of inventory for all stock plans, $1.2 million and $3.4 million, respectively, were amortized into cost of sales and $2.4 million remained in inventory at July 4, 2020. During the three and nine months ended June 29, 2019, $1.2 million and $3.6 million of stock-based compensation cost, respectively, was capitalized as part of inventory for all stock plans, $1.2 million and $3.6 million, respectively, were amortized into cost of sales and $1.5 million remained in inventory at June 29, 2019. 
 
At July 4, 2020, the total compensation cost related to unvested stock-based awards granted to employees under our stock plans but not yet recognized was approximately $49.5 million. We do not estimate forfeitures. This cost will be amortized on a straight-line basis over a weighted-average period of approximately 1.4 years.

Performance-based restricted stock units included at 100% of target goal; under the terms of the total shareholder return performance restricted stock units, the recipient may earn between 0% and 200% of the award while under the terms of the free cash flow performance restricted stock units, the recipient may earn between 0% and 100% of the award.


13.      COMMITMENTS AND CONTINGENCIES

Indemnifications

In the normal course of business, we enter into agreements that contain a variety of representations and warranties and provide for general indemnification. Exposure under these agreements is unknown because claims may be made against us in the future and we may record charges in the future as a result of these indemnification obligations. As of July 4, 2020, we did not have any material indemnification claims that were probable or reasonably possible.

Legal Proceedings

We are subject to claims and litigation arising in the ordinary course of business, such as contract-related, product sales and servicing, real estate, product liability, regulatory matters, employment or intellectual property claims.

Although we do not expect that such claims and litigation will ultimately have a material adverse effect on our consolidated financial position, results of operations or cash flows, an adverse result in one or more matters could negatively affect our results in the period in which they occur, or in future periods.

The United States and many foreign governments impose tariffs and duties on the import and export of certain products we sell. From time to time our customs compliance, product classifications, duty calculations and payments are reviewed or audited by government agencies. Any adverse result in such a review or audit could negatively affect our results in the period in which they occur, or in future periods.

German authorities are currently investigating an export compliance matter involving one of our German subsidiaries involving four former employees (whose employment was terminated following our discovery of this matter). While under German law the subsidiary can be held liable for certain infringements by its employees of German export control laws, we believe that this matter involves less than approximately 1.5 million Euros in transactions in the period currently under investigation and do not believe that the final resolution of this matter will be material to our consolidated financial position, results of operations or cash flows. However, the German government investigation is ongoing and it is possible that substantial payments, fines, penalties or damages could result. Even though we do not currently expect this matter to be material to our consolidated financial position, results of operations or cash flows, circumstances could change as the investigation progresses.


14.      STOCK REPURCHASES

On October 28, 2018, our board of directors authorized a stock repurchase program authorizing the Company to repurchase up to $250.0 million of our common stock through December 31, 2019, with a limit of no more than $75.0 million per quarter. During fiscal 2019, we repurchased and retired 603,828 shares of outstanding common stock under this program at an average price of $128.20 per share for a total of $77.4 million. We made no repurchases under the program during fiscal 2020 and the program expired on December 31, 2019.

On February 5, 2020, our board of directors authorized a stock repurchase program authorizing the Company to repurchase up to $100.0 million of our common stock through January 31, 2021.We made no repurchases under the program through July 4, 2020.


15.  EARNINGS PER SHARE
 
Basic earnings per share is computed based on the weighted average number of shares outstanding during the period, excluding unvested restricted stock. Diluted earnings per share is computed based on the weighted average number of shares outstanding during the period increased by the effect of dilutive employee stock awards, including stock options, restricted stock awards and stock purchase plan contracts, using the treasury stock method.

For the three and nine months ended July 4, 2020, all potentially dilutive securities have been excluded from the from the diluted share calculation as we reported a net loss.

A total of 0 and 97,420 potentially dilutive securities have been excluded from the diluted share calculation for the three and nine months ended June 29, 2019, respectively, as their effect was anti-dilutive.

17.  INCOME TAXES
 
Income tax expense includes a provision for federal, state and foreign taxes based on the annual estimated effective tax rate applicable to us and our subsidiaries, adjusted for items which are considered discrete to the period.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") was enacted and signed into law. U.S. GAAP rules require recognition of the tax effects of new legislation during the reporting period that includes the enactment date. The CARES Act, among other things, includes tax provision changes that benefit business entities and it makes certain technical corrections to the Tax Act. The tax relief measures for business include a five-year net operating loss (“NOL”) carryback, suspension of the annual deduction limitation for net operating losses generated in a tax year beginning after December 31, 2017, changes in the deductibility of interest, acceleration of alternative minimum tax credit refunds, payroll tax relief, and technical corrections allowing accelerated deductions for qualified improvement property. The CARES Act also provides other non-tax benefits, including employee retention credits, to assist businesses impacted by the pandemic. We are currently evaluating the income tax benefits of the CARES Act.

Our effective tax rate on loss before income taxes for the three and nine months ended July 4, 2020 reflected a provision at a 59.6% rate and a benefit at a 6.9% rate, respectively. Our effective tax rate for the three months ended July 4, 2020 was unfavorably impacted primarily due to the establishment of valuation allowances for certain deferred tax assets. Our effective tax rate for the nine months ended July 4, 2020 was unfavorably impacted primarily due to the impairment of goodwill that is not deductible for tax purposes and the establishment of valuation allowances for certain deferred tax assets. These unfavorable impacts were partially offset by the release of unrecognized tax benefits net of settlements and competent authority offsets, the geographic distribution of the impairments of certain long-lived assets that are deductible for tax purposes and the reduction in foreign earnings subject to foreign tax rates that are higher than the U.S. tax rates. Our
28

effective tax rate is based on forecasted annual results and these amounts may fluctuate significantly through the rest of the year as a result of the unpredictable impact of COVID-19 on our operating activities.

        Our effective tax rate on income (loss) before income taxes for the three and nine months ended June 29, 2019 was a benefit at a 73.2% rate and a provision at a 6.2% rate, respectively. Our effective tax rate for the three months ended June 29, 2019 reflected the recognition of a tax benefit on a pre-tax loss. This loss was in part a result of the restructuring costs in the third quarter of fiscal 2019 in our German operations resulting from our decision to relocate the manufacturing and engineering of our High Power Fiber Lasers ("HPFL") products at our Hamburg, Germany facility to our Tampere, Finland location and exit a portion of our HPFL business. A benefit in a high tax jurisdiction increases the effective tax rate on a loss. Furthermore, revision of the estimated annual effective tax rate in the three months ended June 29, 2019 resulted in additional benefit to the period and cumulatively offset tax expense recorded through the previous quarter. Our effective tax rate for the nine months ended June 29, 2019 was lower than the U.S. federal tax rate of 21.0% primarily due to the tax benefit from German losses subject to higher tax rates than U.S. tax rates, the excess tax benefits from restricted stock unit vesting, the benefit of federal research and development tax credits and our Singapore and South Korea tax exemptions. These amounts were partially offset by an accrual for foreign withholding taxes on certain current year foreign earnings not considered permanently reinvested, stock-based compensation not deductible for tax purposes and limitations on the deductibility of compensation under IRC Section 162(m).

The following table summarizes the activity related to our gross unrecognized tax benefits for the nine months ended July 4, 2020 (amounts in thousands):

18.  DEFINED BENEFIT PLANS
 
For the three and nine months ended July 4, 2020, net periodic cost under our defined benefit plans was $0.6 million and $1.4 million, respectively. For the three and nine months ended June 29, 2019, net periodic cost (benefit) under our defined benefit plans was a benefit of $0.4 million and $0.2 million, respectively. The service cost component of net periodic costs is included in selling, general and administrative ("SG&A") expenses, and the interest costs, net actuarial (gain) loss and other components are included in Other—net in the condensed consolidated statements of operations.


19.  SEGMENT AND GEOGRAPHIC INFORMATION

At July 4, 2020, we were organized into two reporting segments, OEM Laser Sources ("OLS") and Industrial Lasers & Systems ("ILS"), based upon our organizational structure and how the CODM receives and utilizes information provided to
29

allocate resources and make decisions. This segmentation reflects the go-to-market strategies and synergies for our broad portfolio of laser technologies and products. While both segments deliver cost-effective, highly reliable photonics solutions, the OLS business segment is focused on high performance laser sources and complex optical sub-systems, typically used in microelectronics manufacturing, medical diagnostics and therapeutic applications, as well as in scientific research. Our ILS business segment delivers high performance laser sources, sub-systems and tools primarily used for industrial laser materials processing, serving important end markets like automotive, machine tool, consumer goods and medical device manufacturing.
 
We have identified OLS and ILS as operating segments for which discrete financial information is available. Both units have dedicated engineering, manufacturing, product business management and product line management functions. A small portion of our outside revenue is attributable to projects and recently developed products for which a segment has not yet been determined. The associated direct and indirect costs are presented in the category of Corporate and other, along with other corporate costs as described below.

Our Chief Executive Officer has been identified as the CODM, as he assesses the performance of the segments and decides how to allocate resources to the segments. Income from operations is the measure of profit and loss that our CODM uses to assess performance and make decisions. Assets by segment are not a measure used to assess the performance of the company by the CODM and thus are not reported in our disclosures. Income from operations represents the net sales less the cost of sales and direct operating expenses incurred within the operating segments as well as allocated expenses such as shared sales and manufacturing costs. We do not allocate certain operating expenses to our operating segments and we manage them at the corporate level. These unallocated costs include stock-based compensation and corporate functions (certain research and development, management, finance, legal and human resources) and are included in the results below under Corporate and other in the reconciliation of operating results. Management does not consider unallocated Corporate and other costs in its measurement of segment performance.

The following table provides net sales and income (loss) from operations for our operating segments and a reconciliation of our total income (loss) from operations to income (loss) before income taxes (in thousands):

20.  RESTRUCTURING CHARGES

In the first quarter of fiscal 2017, we began the implementation of planned restructuring activities in connection with the acquisition of Rofin. The activities under this plan primarily related to the exiting of our legacy HPFL product line, change of control payments to Rofin officers, the exiting of two product lines acquired in the acquisition of Rofin, realignment of our supply chain due to segment reorganization and consolidation of sales and distribution offices as well as certain manufacturing sites. These activities resulted in charges primarily for employee termination, other exit related costs associated with the write-off of property and equipment and inventory and early lease termination costs.

In June 2019, we announced our plans to co-locate the manufacturing and engineering of our HPFL products at our Hamburg, Germany facility to our Tampere, Finland location and exit a portion of our HPFL business. In conjunction with this announcement, we recorded charges in the third quarter of fiscal 2019 of $20.9 million primarily related to write-offs of excess inventory, which is recorded in cost of sales, and estimated severance. We recorded charges in the first, second and third quarters of fiscal 2020 of $0.6 million, $0.5 million and $0.1 million, respectively, primarily related to accelerated depreciation and project management consulting.

We have also announced our intent to vacate our leased facility in Santa Clara at the end of the current lease term in calendar 2020 and combine operations at our Santa Clara headquarters. We exited this facility on July 31, 2020. We did not incur material expenses in fiscal 2019 related to this project. We incurred costs in the first, second and third quarters of fiscal 2020 of $0.2 million, $0.6 million and $0.4 million, respectively, related to this project. We also incurred costs in the first quarter of fiscal 2020 of $0.1 million for other projects.

The following table presents our current liability as accrued on our balance sheets for restructuring charges. The table sets forth an analysis of the components of the restructuring charges and payments and other deductions made against the accrual for the quarters of fiscal 2020 and 2019 (in thousands):

At July 4, 2020, $1.1 million of accrued severance related and other costs were included in other current liabilities. The asset write-offs for accelerated depreciation and other costs in the first, second and third quarters of fiscal 2020 primarily related to the exit of a portion of our HPFL business in Hamburg, Germany, and costs to vacate our leased facility in Santa Clara and combine operations at our Santa Clara headquarters. The severance related, asset write-offs of inventory and other costs in the first nine months of fiscal 2019 primarily related to the exit of a portion of our HPFL business in Hamburg, Germany.

By segment, $0.1 million and $1.3 million of restructuring costs were incurred in the ILS segment and $0.4 million and $1.2 million were incurred in the OLS segment in the three and nine months ended July 4, 2020, respectively. In the three and nine months ended June 29, 2019, all of the restructuring costs were incurred in the ILS segment and none were incurred in the OLS segment. Restructuring charges are recorded in cost of sales, research and development and selling, general and administrative expenses in our condensed consolidated statements of operations.

ITEM 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
COMPANY OVERVIEW
 
BUSINESS BACKGROUND
 
We are one of the world’s leading providers of lasers, laser-based technologies and laser-based system solutions in a broad range of commercial, industrial and scientific applications. We design, manufacture, service and market lasers and related accessories for a diverse group of customers. Since inception in 1966, we have grown through internal expansion and through strategic acquisitions of complementary businesses, technologies, intellectual property, manufacturing processes and product offerings.
 
We are organized into two reporting segments: OEM Laser Sources ("OLS") and Industrial Lasers & Systems ("ILS"), based on the organizational structure of the company and how the chief operating decision maker ("CODM") receives and utilizes information provided to allocate resources and make decisions. This segmentation reflects the go-to-market strategies and synergies for our broad portfolio of laser technologies and products. While both segments deliver cost-effective, highly reliable photonics solutions, the OLS business segment is focused on high performance laser sources and complex optical sub-systems typically used in microelectronics manufacturing, medical diagnostics and therapeutic applications, as well as in scientific research. Our ILS business segment delivers high performance laser sources, sub-systems and tools primarily used for industrial laser materials processing, serving important end markets like automotive, machine tool, consumer goods and medical device manufacturing.

Income from operations is the measure of profit and loss that our CODM uses to assess performance and make decisions. Income from operations represents the sales less the cost of sales and direct operating expenses incurred within the operating segments as well as allocated expenses such as shared sales and manufacturing costs. We do not allocate certain operating expenses to our operating segments and we manage them at the corporate level. These unallocated costs include stock-based compensation and corporate functions (certain advanced research and development, management, finance, legal and human resources) and are included in Corporate and other. Management does not consider unallocated Corporate and other costs in its measurement of segment performance.

MARKET APPLICATIONS
 
Our products address a broad range of applications that we group into the following markets: Microelectronics, Materials Processing, OEM Components and Instrumentation and Scientific and Government Programs.
 
OUR STRATEGY

We strive to develop innovative and proprietary products and solutions that meet the needs of our customers and that are based on our core expertise in lasers and optical technologies. In pursuit of our strategy, we intend to:
Leverage our technology portfolio and application engineering to lead the proliferation of photonics into broader markets—We will continue to identify opportunities in which our technology portfolio and application engineering can be used to offer innovative solutions and gain access to new markets. We plan to utilize our expertise to increase our market share in mid to high power material processing applications.
Streamline our manufacturing structure and improve our cost structure—We will focus on optimizing the mix of products that we manufacture internally and externally. We will utilize vertical integration where our internal manufacturing process is considered proprietary and seek to leverage external sources when the capabilities and cost structures are well developed and on a path towards commoditization.
Focus on long-term improvement of adjusted EBITDA, in dollars and as a percentage of net sales—We define adjusted EBITDA as operating income adjusted for depreciation, amortization, stock compensation expense, major restructuring costs and certain other non-operating income and expense items, such as costs related to our acquisitions. Key initiatives to reach our goals for EBITDA improvements include utilization of our Asian manufacturing locations, optimizing our supply chain and continued leveraging of our infrastructure.
Optimize our leadership position in existing markets—There are a number of markets where we have historically been at the forefront of technological development and product deployment and from which we have derived a substantial portion of our revenues. We plan to optimize our financial returns from these markets.
33

Table of Contents
Maintain and develop additional strong collaborative customer and industry relationships—We believe that the Coherent brand name and reputation for product quality, technical performance and customer satisfaction will help us to further develop our loyal customer base. We plan to maintain our current customer relationships and develop new ones with customers who are industry leaders and work together with these customers to design and develop innovative product systems and solutions as they develop new technologies.
Develop and acquire new technologies and market share—We will continue to enhance our market position through our existing technologies and develop new technologies through our internal research and development efforts, as well as through the acquisition of additional complementary technologies, intellectual property, manufacturing processes and product offerings.


APPLICATION OF CRITICAL ACCOUNTING POLICIES
 
Our discussion and analysis of financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America and pursuant to the rules and regulations of the SEC. The preparation of these condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. We have identified the following as the items that require the most significant judgment and often involve complex estimation: revenue recognition, business combinations, accounting for long-lived assets (including goodwill and intangible assets), inventory valuation, warranty reserves and accounting for income taxes. See Item 7. "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for our fiscal year ended September 28, 2019.
 

KEY PERFORMANCE INDICATORS
 
Below is a summary of some of the quantitative performance indicators (as defined below) that are evaluated by management to assess our financial performance. Some of the indicators are non-GAAP measures and should not be considered as an alternative to any other measure for determining operating performance or liquidity that is calculated in accordance with generally accepted accounting principles.

Net Sales
 
Net sales include sales of lasers, laser systems, related accessories and services. Net sales for the third quarter of fiscal 2020 decreased 10.5% in our OLS segment and decreased 14.5% in our ILS segment from the same quarter one year ago. Net sales for the first nine months of fiscal 2020 decreased 17.8% in our OLS segment and decreased 15.0% in our ILS segment from the same period one year ago. For a description of the reasons for changes in net sales refer to the "Results of Operations" section of this quarterly report.

Gross Profit as a Percentage of Net Sales
 
Gross profit as a percentage of net sales ("gross profit percentage") is calculated as gross profit for the period divided by net sales for the period. Gross profit percentage in the third quarter of fiscal 2020 increased to 46.6% from 45.1% in our OLS segment and increased to 9.9% from 4.6% in our ILS segment as compared to the same quarter one year ago. Gross profit percentage in the first nine months of fiscal 2020 decreased to 46.4% from 47.6% in our OLS segment and decreased to 12.4% from 13.9% in our ILS segment as compared to the same period one year ago. For a description of the reasons for changes in gross profit refer to the "Results of Operations" section of this quarterly report.
 
Research and Development as a Percentage of Net Sales
 
Research and development as a percentage of net sales ("R&D percentage") is calculated as research and development expense for the period divided by net sales for the period. Management considers R&D percentage to be an important indicator in managing our business as investing in new technologies is a key to future growth. R&D percentage increased to 9.5% for the third quarter of fiscal 2020 from 9.0% for the same quarter one year ago and increased to 9.5% for the first nine months of fiscal 2020 from 8.2% for the same period one year ago. For a description of the reasons for changes in R&D spending refer to the "Results of Operations" section of this quarterly report.
 
Net Cash Provided by Operating Activities
 
Net cash provided by operating activities as reflected on our Condensed Consolidated Statements of Cash Flows primarily represents the excess of cash collected from billings to our customers and other receipts over cash paid to our vendors for expenses and inventory purchases to run our business. We believe that cash flows from operations is an important performance indicator because cash generation over the long term is essential to maintaining a healthy business and providing funds to help fuel growth. For a description of the reasons for changes in net cash provided by operating activities refer to the "Liquidity and Capital Resources" section of this quarterly report.
 
Free Cash Flow
 
Free cash flow represents net cash provided by operating activities reduced by purchases of property and equipment, both as reflected on our Condensed Consolidated Statements of Cash Flows. We believe that free cash flow is an important
35

Table of Contents
performance indicator because it is a measure of cash generation after accounting for cash outflows to support operations and maintain capital assets. Cash generation over the long term is essential to maintaining a healthy business and providing funds to help fuel growth. For a description of the reasons for changes in free cash flow refer to the "Liquidity and Capital Resources" section of this quarterly report, where we discuss the reasons for changes in net cash provided by operating activities.

Days Sales Outstanding in Receivables
 
We calculate days sales outstanding ("DSO") in receivables as net receivables at the end of the period divided by net sales during the period and then multiplied by the number of days in the period, using 90 days for quarters. DSO in receivables indicates how well we are managing our collection of receivables, with lower DSO in receivables resulting in higher working capital availability. The more money we have tied up in receivables, the less money we have available for research and development, acquisitions, expansion, marketing and other activities to grow our business. Our DSO in receivables for the third quarter of fiscal 2020 decreased to 60 days from 71 days compared to the same quarter one year ago. The decrease was primarily due to improved collections of receivables for ELA tools used in the Asian flat panel display market, improved linearity with a lower concentration of sales in the last month of the quarter and the impact of lower sales volumes. These ELA tools are generally our highest priced products, so any changes in collection timing will have a more significant impact on overall DSO than our other products.

Annualized Third Quarter Inventory Turns
 
We calculate annualized third quarter inventory turns as the cost of sales during the third quarter annualized and divided by net inventories at the end of the third quarter. This indicates how well we are managing our inventory levels, with higher inventory turns resulting in more working capital availability and a higher return on our investments in inventory. Our annualized inventory turns for the third quarter of fiscal 2020 decreased to 1.8 turns from 2.1 turns compared to the same quarter a year ago, primarily in the ILS segment, due to the impact of higher restructuring costs associated with our exit of the High Power Fiber Lasers ("HPFL") business in the third quarter of fiscal 2019 compared to the third quarter of fiscal 2020 as well as lower service revenues from shipments of consumable service parts in our OLS segment in the third quarter of fiscal 2020. Our annualized inventory turns are lower than our historical turns as we continue to carefully manage our inventory levels in anticipation of expected increased demand from our customers over the next 12 to 18 months.

Adjusted EBITDA as a Percentage of Net Sales

We define adjusted EBITDA as operating income adjusted for depreciation, amortization, stock compensation expense, major restructuring costs and certain other non-operating income and expense items, such as costs related to our acquisitions. Key initiatives to reach our goals for EBITDA improvements include utilization of our Asian manufacturing locations, optimizing our supply chain and continued leveraging of our infrastructure.

We utilize a number of different financial measures, both GAAP and non-GAAP, such as free cash flow and adjusted EBITDA as a percentage of net sales, in analyzing and assessing our overall business performance, for making operating decisions and for forecasting and planning future periods. We consider the use of non-GAAP financial measures helpful in assessing our current financial performance and ongoing operations. While we use non-GAAP financial measures to enhance our understanding of certain aspects of our financial performance, we do not consider these measures to be a substitute for, or superior to, the information provided by GAAP financial measures. We provide free cash flow and adjusted EBITDA as a percentage of sales in order to enhance investors’ understanding of our ongoing operations. These measures are used by some investors when assessing our performance.

SIGNIFICANT EVENTS

Coronavirus pandemic (COVID-19)

In December 2019, a novel coronavirus disease ("COVID-19") was reported, and in January 2020, the World Health Organization ("WHO") declared it a Public Health Emergency of International Concern. On February 28, 2020, the WHO raised its assessment of the COVID-19 threat from high to very high at a global level due to the continued increase in the number of cases and affected countries, and on March 11, 2020, the WHO characterized COVID-19 as a pandemic. In an effort to contain COVID-19 or slow its spread, governments around the world have enacted various measures, including orders to close all businesses not deemed "essential," isolate residents in their homes or places of residence, and practice social distancing at and away from work. These actions and the global health crisis caused by COVID-19 will continue to negatively impact global business activity, which will continue to negatively affect our revenue and results of operations. Each of the areas where we generate a majority of our revenue including Asia, Europe and North America have been and will continue to be impacted by COVID-19. The timing and extent of impact related to COVID-19 varies by country and region.

Sales for the quarters ended April 4, 2020 and July 4, 2020 were negatively affected by the COVID-19 pandemic. The effect of COVID-19 was most significant in Asia during the quarter ended April 4, 2020 and began impacting Europe and North America only later in the quarter ended April 4, 2020 as the virus spread globally. In the quarter ended July 4, 2020, the global effect of COVID-19 was less significant, though continued to be high in certain jurisdictions. While we believe that COVID-19 was a partial cause of the decline in revenue in the second quarter of fiscal 2020, we also had lower shipments related to ELA tools in the flat panel display market and lower shipments in materials processing applications that were mostly unrelated to COVID-19.

The global demand environment remains very uncertain given the effects of COVID-19 on manufacturing facilities and customer confidence around the world. While we have seen a partial recovery in order volumes in China in the latter half of March and the third quarter of fiscal 2020, this has coincided with declining bookings in other regions, particularly in North America, and to a lesser extent in Europe and other countries in Asia. As such, visibility into a recovery in global demand remains uncertain at this time.

Currently, our major production facilities in Europe and Southeast Asia and most of our production facilities in the United States remain open. At all our locations, we have transitioned from Business Continuity Plans to Return to Operations Plans while continuing to maintain high standards of employee safety and sanitization protocols. Our Return to Operations Plans have a phased approach with the primary focus on employee safety. We have vertically integrated manufacturing, and many of the components produced at certain of our facilities supply other company facilities, are single sourced internally and are not available from third-party suppliers (for example our semiconductor diodes manufactured in Santa Clara, California). While we do maintain a safety stock of critical components at our various locations, the scope, timing and duration of various government restrictions to address the COVID-19 outbreak could impact our internal supply chain. We have implemented certain payroll and other policy changes to help support our employees impacted by COVID-19. These measures have and will continue to increase the cost of our operations but the magnitude and length of time of this impact is difficult to quantify at this time and may continue to be difficult to estimate in the future. If our revenues are reduced for an extended period or if our production output falls because of government restrictions, we may be required to reduce payroll-related costs and other expenses in the future through layoffs or furloughs, even though we have not done so to date.

We have not experienced significant supply disruption from third-party component suppliers. However, we continue to face some supply chain constraints primarily related to logistics, including available air cargo space and higher freight rates. Available cargo space on flights between the U.S. and Europe, and Europe and Asia has been and remains limited as a result of the impacts from COVID-19 and government and business responses to it, and this has increased shipping time and costs. In addition, shipments between countries have been more severely impacted by COVID-19 and we are experiencing delays due to additional checks at border crossings, including within Europe and Asia. There has also been sporadic restrictions on individual travel between certain states in the United States of America as well. Government actions related to COVID-19 come on the heels of increasing trade tensions between the United States and China, which may continue. We believe we have the ability to meet the near-term demand for our products, but the situation is fluid and subject to change.

We continue to monitor the rapidly evolving conditions and circumstances as well as guidance from international and domestic authorities, including public health authorities, and we may need to take additional actions based on their recommendations. There is considerable uncertainty regarding the impact on our business stemming from current measures and potential future measures that could restrict access to our facilities, limit our manufacturing and support operations and place restrictions on our workforce, customers and suppliers. The measures implemented by various authorities related to the COVID-19 outbreak have caused us to change our business practices including those related to where employees work, the distance between employees in our facilities, limitations on in-person meetings between employees and with customers, suppliers, service providers, and stakeholders as well as restrictions on some shipping activities, business travel to domestic and international locations or to attend trade shows, investor conferences and other events.

The COVID-19 pandemic has significantly increased worldwide and regional economic uncertainty and decreased demand for our products in many markets we serve, which could continue for an unknown period of time. In these circumstances, there may be developments outside of our control, including the length and extent of the COVID-19 outbreak, government-imposed measures and our ability to ship products and/or service installed products that may require us to adjust our operating plans. As such, given the dynamic nature of this situation, we cannot estimate with certainty the future impacts of COVID-19 on our financial condition, results of operations or cash flows. However, we do expect that it will have an adverse impact on our revenue as well as our overall profitability and may lead to an increase in inventory provisions, allowances for credit losses, and a volatile effective tax rate driven by changes in the mix of earnings across our markets.

See the additional Risk Factor included in Part II-Item 1A of this quarterly report regarding the impact of COVID-19.

Goodwill and other impairment charges

Based on our internal projections and the preparation of our financial statements for the quarter ended April 4, 2020, and considering the forecasted decrease in demand due to the COVID-19 pandemic and other factors, we believed that the fair value of our ILS reporting unit might no longer have exceeded its carrying value and performed an interim goodwill impairment test on the ILS and OLS reporting units. Based on the estimated fair value of the ILS reporting unit, in the quarter ended April 4, 2020, we recorded non-cash pre-tax goodwill impairment charges of $327.2 million. In addition, we performed impairment tests on the long-lived assets allocated to the asset group of the ILS reporting unit, including intangible assets, property, plant and equipment and ROU assets as of April 4, 2020 and recorded non-cash pre-tax charges, in the quarter ended April 4, 2020, related to the impairment intangible assets, property, plant and equipment and ROU assets of the ILS reporting unit of $33.9 million, $85.6 million and $1.8 million, respectively. See Note 8, "Goodwill and Intangible Assets" and Note 11, "Leases" in the Notes to Condensed Consolidated Financial Statements.

Restructuring

In June 2019, we internally announced our plans to co-locate the manufacturing and engineering of our HPFL products at our Hamburg, Germany facility to our Tampere, Finland location and exit a portion of our HPFL business. In conjunction with this announcement, we recorded restructuring charges in fiscal 2019 of $19.7 million. The charges primarily relate to write-offs of excess inventory, which is recorded in cost of sales, and estimated severance. We recorded charges in the three and nine months ended July 4, 2020 of $0.1 million and $1.2 million, respectively, primarily related to accelerated depreciation and project management consulting. See Note 20, "Restructuring Charges" in the Notes to Condensed Consolidated Financial Statements.

We have also announced our intent to vacate our leased facility in Santa Clara at the end of the current lease term in calendar 2020 and combine operations at our Santa Clara headquarters. We did not incur material expenses in fiscal 2019 related to this project. We incurred costs in the three and nine months ended July 4, 2020 of $0.4 million and $1.2 million, respectively, related to this project.

Quarterly

Net sales for the third quarter of fiscal 2020 decreased by $40.8 million, or 12%, compared to the third quarter of fiscal 2019, with significant decreases in the materials processing, OEM components and instrumentation and scientific and government programs markets with a smaller decrease in the microelectronics market. The decrease included lower net sales of approximately $9.0 million due to the impact from COVID-19 shelter-in place orders and/or delays in restarting non-essential manufacturing activity at many of our customers, primarily in the materials processing, OEM components and instrumentation and scientific and government programs markets.

The decrease in the microelectronics market of $1.4 million, or 1%, was primarily due to decreased shipments for flat panel display (higher shipments related to ELA tools used in the flat panel display market offset by lower revenues from consumable service parts) and semiconductor applications, partially offset by higher shipments for advanced packaging applications. We expect future increases in ELA tool shipments as Asian manufacturers improve yields and ramp manufacturing; however, the timing of any such increase is uncertain at this time, which is further impacted by COVID-19. In addition, it is expected that the handset market will transition to 5G. 5G technology requires more power from the battery which we expect will result in the handset manufacturers having to decide between shorter talk times or placement of larger batteries in existing form factors. Since OLED displays are much thinner than liquid crystal displays (LCD), we believe 5G will increase demand for OLED displays to accommodate larger batteries. We believe that these technological demands will allow us to continue to maintain a leadership position in flat panel display applications.

The decrease in the materials processing market of $19.7 million, or 19%, was due to decreased sales in materials processing applications in a variety of areas. An index which often correlates to materials processing sales is the Purchasing Managers Index (PMI). PMI is a measure of the prevailing economic trends in manufacturing. Manufacturing PMI has been in a contraction state (<50 on the index) in Korea, Taiwan, the EUROZONE and the U.S. for a year or so. Additionally, other markets for sales of these applications have also been depressed (e.g. automobiles). We see some strength in non-metal applications such as packaging, medical device manufacturing and specialty semiconductor marking. Even before COVID-19, demand in the materials processing market was softening in some of the machine tool industries and the materials processing market continues to be negatively impacted by COVID-19. We are also seeing increased price and margin pressure from Chinese competitors in this market. The timing for our recovery in this market is uncertain.

The decrease in the OEM components and instrumentation market of $10.8 million, or 17%, was due primarily to lower shipments for medical applications. We expect strength in the healthcare market over the next several years. We supply lasers

and optical systems for biomedical instrumentation applications and our lasers have been used in diagnostic instruments in applications including gene sequencing, biomarker identification and vaccine development. Applications dependent on discretionary spending by consumers, including tools and components used in discretionary medical procedures, as well as certain research applications continue to be negatively impacted by COVID-19, but we are seeing indications that the market is starting to recover. We expect the defense market, especially amplifiers for directed energy, countermeasures as well as specialty optics for aerospace, to be a multi-year growth opportunity for us.

Sales in the scientific and government programs market decreased $9.0 million, or 30%, due to lower demand for advanced research applications used by university and government research groups, primarily in Asia and the United States, due to the closures of universities and other research institutions due to COVID-19 shelter-in-place orders. We expect demand in the scientific and government programs market to continue to fluctuate from quarter to quarter.

Year-to-date

Net sales for the first nine months of fiscal 2020 decreased by $182.9 million, or 17%, compared to the first nine months of fiscal 2019, with significant decreases in the microelectronics and materials processing markets and smaller decreases in the scientific and government programs and OEM components and instrumentation markets. The decrease included lower net sales of approximately $35.0 to $40.0 million due to the impact from COVID-19 shelter-in place orders as well as delays in restarting non-essential manufacturing activity at many of our customers, which impacted all of our markets.

The decrease in the microelectronics market of $96.7 million, or 20%, was primarily due to weaker demand resulting in lower shipments related to ELA tools used in the flat panel display market as well as lower revenues from consumable service parts and a decrease due to a non-recurring fee of $7.0 million that was recognized in the first quarter of fiscal 2019 related to the cancellation of orders from a customer for our ELA tools. In microelectronics, orders in the first nine months of fiscal 2020 increased significantly for ELA tools as compared to the first nine months of fiscal 2019.

Sales in the materials processing market decreased $54.6 million, or 18%, primarily due to decreased sales in marking, cutting and welding applications, primarily in China, other Asia-Pacific countries and Europe, and to a lesser extent in the United States, primarily due to a significant decrease in PMI’s worldwide in fiscal 2020 and a weakened global market for automobiles.

The decrease in the OEM components and instrumentation market of $11.4 million, or 6%, was due primarily to lower shipments for medical applications partially offset by higher shipments for bio-instrumentation applications.

Sales in the scientific and government programs market decreased $20.2 million, or 21%, due to lower demand for advanced research applications used by university and government research groups, primarily in Asia and the United States, due to the closures of universities and research institutions due to COVID-19 shelter-in-place orders.

Segments
 
We are organized into two reportable operating segments: OLS and ILS. While both segments deliver cost-effective, highly reliable photonics solutions, OLS is focused on high performance laser sources and complex optical sub-systems, typically used in microelectronics manufacturing, medical diagnostics and therapeutic applications, as well as in scientific research. ILS delivers high performance laser sources, sub-systems and tools primarily used for industrial laser materials processing, serving important end markets like automotive, machine tool, consumer goods and medical device manufacturing.

Quarterly

Net sales for the third quarter of fiscal 2020 decreased by $40.8 million, or 12%, compared to the third quarter of fiscal 2019, with decreases of $21.6 million, or 10%, in our OLS segment and $19.2 million, or 14%, in our ILS segment.
 
The decrease in our OLS segment sales, including lower sales of approximately $1.0 million due to COVID-19, was primarily due to lower demand for advanced research applications used by university and government research groups, primarily in Asia and the United States as well as decreased sales during the period in materials processing, bio-instrumentation, medical, military, advanced packaging, flat panel display and semiconductor applications. Within flat panel display applications, lower revenues from consumable service parts were offset by higher shipments of ELA tools. The decrease in our ILS segment sales, including lower sales of approximately $8.0 million due to COVID-19, was primarily due to lower sales for materials processing and lower sales for medical applications within the OEM components and instrumentation market.

Year-to-date

Net sales for the first nine months of fiscal 2020 decreased by $182.9 million, or 17%, compared to the first nine months of fiscal 2019, with decreases of $120.9 million, or 18%, in our OLS segment and $62.1 million, or 15%, in our ILS segment.
 
The decrease in sales in our OLS segment, including lower sales of approximately $26.0 million due to COVID-19, was primarily due to weaker demand resulting in lower shipments of ELA tools used in the flat panel display market as well as lower revenues from consumable service parts and a decrease due to a non-recurring fee of $7.0 million that was recognized in the first quarter of fiscal 2019 related to the cancellation of orders from one customer for our ELA tools. In addition, OLS sales decreased due to lower demand for advanced research applications used by university and government research groups, primarily in Asia and the United States. The decrease in our ILS segment sales, including lower sales of approximately $14.0 million due to COVID-19, was primarily due to lower sales for materials processing and lower sales for medical applications within the OEM components and instrumentation market.

GROSS PROFIT
 
Consolidated

Our gross profit percentage increased by 3.0% to 31.9% in the third quarter of fiscal 2020 from 28.9% in the third quarter of fiscal 2019 and decreased by 1.8% to 32.7% in the first nine months of fiscal 2020 from 34.5% in the first nine months of fiscal 2019.

The 3.0% increase in gross profit percentage during the third quarter of fiscal 2020 included a 5.1% favorable impact of lower restructuring costs, primarily related to the write-off of inventories and severance costs in the third quarter of fiscal 2019 due to our exit from a portion of our HPFL business and 2.7% lower amortization of intangibles primarily due to the impairment of ILS intangibles in the second quarter of fiscal 2020. Excluding the 7.8% favorable impact of lower restructuring costs and intangibles amortization, gross profit percentage decreased 4.8% compared to the third quarter of fiscal 2019 primarily due to higher other costs (4.3%), unfavorable product costs (0.2%) and higher stock-based compensation (0.3%) as a percentage of sales. Other costs were higher primarily due to higher inventory provisions for excess and obsolete inventory costs in certain ILS business units due to lower forecasted demand and changing business conditions partially offset by lower provisions for excess and obsolete inventory costs in certain OLS business units. Unfavorable product margins in ILS due to unfavorable absorption of manufacturing costs on lower volumes over multiple products and the impact of lower shipments of higher margin tools products were partially offset by more favorable margins in OLS as a result of the favorable impact of higher

Table of Contents
margins (both mix and cost reductions) in our OEM Components and Instrumentation market and the favorable impact of the weaker Euro partially offset by less favorable margins due to lower shipments of higher margin flat panel display systems.

The 1.8% decrease in gross profit percentage during the first nine months of fiscal 2020 included a 1.5% favorable impact of lower restructuring costs, primarily related to the write-off of inventories and severance costs in the third quarter of fiscal 2019 due to our exit from a portion of our HPFL business and 0.7% lower amortization of intangibles primarily due to the impairment of ILS intangibles in the second quarter of fiscal 2020. Excluding the 2.2% favorable impact of lower restructuring costs and intangibles amortization, gross profit percentage decreased 4.0% primarily due to unfavorable product margins (2.4%), higher other costs (1.8%) and higher stock-based compensation expense (0.1%) as a percentage of sales partially offset by lower warranty and installation costs (0.3%) as a percentage of sales. The unfavorable product margins were in both segments and were primarily due to unfavorable absorption of manufacturing costs on lower volumes including the impact of idle facilities due to COVID-19 as well as unfavorable product margins in OLS as a result of lower shipments of higher margin flat panel display systems. In addition, the unfavorable impact (0.4%) of a $7.0 million non-recurring fee recognized in the first quarter of fiscal 2019 related to the cancellation of orders from one customer for our ELA tools contributed to the decrease. Other costs were higher primarily due to higher inventory provisions for excess and obsolete inventory in certain ILS business units due to lower forecasted demand and changing business conditions, net of lower inventory provisions for excess and obsolete inventory in certain OLS business units. The lower warranty and installation costs were primarily in our ILS segment and included lower warranty events with the largest impact from fiber lasers, primarily sold into China, partially offset by the impact of lower sales volumes.

Our gross profit percentage has been and will continue to be affected by a variety of factors including the impact of COVID-19, shipment volumes, product mix, pricing on volume orders, our ability to manufacture advanced and more complex products, manufacturing efficiencies, excess and obsolete inventory write-downs, warranty costs, amortization of intangibles, pricing by competitors or suppliers, new product introductions, production volume, customization and reconfiguration of systems, commodity prices and foreign currency fluctuations against the U.S. Dollar, particularly the recent volatility of the Euro and to a lesser extent, the Japanese Yen and South Korean Won. Our gross profit in future quarters will continue to be favorably impacted by lower amortization and depreciation as a result of the impairments of long-lived assets in our ILS segment in the second quarter of fiscal 2020.

OEM Laser Sources
 
The gross profit percentage in our OLS segment increased by 1.5% to 46.6% in the third quarter of fiscal 2020 from 45.1% in the third quarter of fiscal 2019. The gross profit percentage in our OLS segment decreased by 1.2% to 46.4% in the first nine months of fiscal 2020 from 47.6% in the first nine months of fiscal 2019.

The 1.5% increase in gross profit percentage during the third quarter of fiscal 2020 was primarily due to favorable product margins (1.2%) as a result of the favorable impact of the CARES Act retention credit (net of the impact of idle facilities and increased safety costs due to COVID-19), the favorable impact of higher margins (both mix and cost reductions) in our OEM Components and Instrumentation market and the favorable impact of the weaker Euro. The favorable impact to product margins was partially offset by unfavorable absorption of manufacturing costs on lower volumes and less favorable margins due to lower shipments of higher margin flat panel display systems. In addition, lower other costs favorably impacted margin by 0.7% primarily due to lower inventory provisions for excess and obsolete inventory in certain business units net of the impact of lower sales volumes as well as lower intangibles amortization (0.2%) as a percentage of sales. The favorable impacts to margin were partially offset by the unfavorable impact of higher warranty costs (0.6%) primarily due increased warranty events in the microelectronics market and the impact of lower sales volumes.

The 1.2% decrease in gross profit percentage during the first nine months of fiscal 2020 was primarily due to unfavorable product margins (1.5%) as a result of the impact of both lower shipments of higher margin flat panel display systems and lower revenues from consumable service parts, the 0.5% unfavorable impact of a $7.0 million non-recurring fee recognized in the first quarter of fiscal 2019 related to the cancellation of orders from one customer for our ELA tools and unfavorable absorption of manufacturing costs on lower volumes. In addition, higher warranty costs (0.1%) unfavorably impacted margins. The unfavorable product margins and warranty costs were partially offset by lower other costs (0.3%) due to lower inventory provisions for excess and obsolete inventory in certain business units as well as lower intangibles amortization (0.1%) as a percentage of sales.

The gross profit percentage in our ILS segment increased by 5.3% to 9.9% in the third quarter of fiscal 2020 from 4.6% in the third quarter of fiscal 2019. The gross profit percentage in our ILS segment decreased by 1.5% to 12.4% in the first nine months of fiscal 2020 from 13.9% in the first nine months of fiscal 2019.

The 5.3% increase in gross profit percentage during the third quarter of fiscal 2020 included a 13.1% favorable impact of lower restructuring costs, primarily related to the write-off of inventories and severance costs in the third quarter of fiscal 2019 due to our exit from a portion of our HPFL business and 6.6% lower amortization of intangibles due to the impairment of ILS intangibles in the second quarter of fiscal 2020. Excluding the 19.7% favorable impact of lower restructuring costs and intangibles amortization, gross profit percentage decreased 14.4% compared to the third quarter of fiscal 2019 primarily due to higher other costs (12.6%) due to higher inventory provisions as a percentage of sales for excess and obsolete inventory in several business units due to lower forecasted demand and changing business conditions and unfavorable product costs (3.0%) due to unfavorable absorption of manufacturing costs on lower volumes over multiple products and the impact of lower shipments of higher margin tools products. The unfavorable costs were partially offset by 1.2% lower warranty and installation costs as a percentage of sales due to fewer warranty events, particularly for our HPFL products sold in China, and for fiber components products.

The 1.5% decrease in gross profit percentage during the first nine months of fiscal 2020 included a 4.1% favorable impact of lower restructuring costs, primarily related to the write-off of inventories and severance costs in the third quarter of fiscal 2019 due to our exit from a portion of our HPFL business and 1.7% lower amortization of intangibles due to the impairment of ILS intangibles in the second quarter of fiscal 2020. Excluding the 5.8% favorable impact of lower restructuring costs and intangibles amortization, gross profit percentage decreased 7.3% primarily due to higher other costs (5.3%) due to higher inventory provisions for excess and obsolete inventory in several business units as a percentage of sales and unfavorable product costs (3.4%) including unfavorable absorption of manufacturing costs on lower volumes over multiple products. The decreases were partially offset by 1.3% lower warranty and installation costs as a percentage of sales due to fewer warranty events, particularly for our HPFL products sold in China, partially offset by higher warranty events for fiber components and diode components products.

Research and development

Quarterly

Research and development ("R&D") expenses decreased $2.4 million, or 8%, during the third quarter of fiscal 2020 compared to the same quarter one year ago. The decrease was primarily due to $3.8 million lower headcount expenses due to lower severance costs, lower spending on projects including the impact of headcount reductions and the favorable impact of foreign exchange rates. Partially offsetting the decreases, R&D expense increased due to $0.7 million higher stock-based compensation expense due to increased grants to employees, $0.6 million net higher spending on materials, including lower customer reimbursements and $0.1 million higher charges for increases in deferred compensation plan liabilities.

On a segment basis as compared to the prior year period, OLS R&D spending increased $0.6 million primarily due to higher net spending on materials and headcount partially offset by the favorable impact of foreign exchange rates. ILS R&D spending decreased $3.4 million primarily due to lower headcount spending including lower restructuring costs for severance and the favorable impact of foreign exchange rates partially offset by higher net spending on materials. Corporate and other R&D spending increased $0.4 million primarily due to higher stock-based compensation expense and higher charges for increases in deferred compensation plan liabilities partially offset by lower headcount spending in our former Advanced Research business unit.

Year-to-date

Research and development ("R&D") expenses decreased $3.3 million, or 4%, during the first nine months of fiscal 2020 compared to the same period one year ago. The decrease was primarily due to $3.7 million lower headcount spending and $0.7 million lower spending on materials, including lower customer reimbursements and the favorable impact of foreign exchange rates (primarily the weaker Euro). Headcount spending decreased $3.7 million due to lower restructuring costs for severance, lower spending on projects including the impact of headcount reductions and the favorable impact of foreign exchange rates partially offset by the impact of an extra week in the second quarter of fiscal 2020. Partially offsetting the decrease, R&D expenses increased $0.8 million due to higher stock-based compensation expense due to increased grants to employees and $0.3 million as a result of higher charges for increases in deferred compensation plan liabilities.

On a segment basis as compared to the prior year period, OLS R&D spending increased $2.0 million primarily due to higher net spending on headcount and materials partially offset by the favorable impact of foreign exchange rates. ILS R&D spending decreased $4.7 million primarily due to lower headcount spending, lower net spending on materials and the favorable impact of foreign exchange rates. Corporate and other R&D spending decreased $0.6 million primarily due to lower headcount spending in our former Advanced Research business unit partially offset by higher stock-based compensation expense and higher charges for increases in deferred compensation plan liabilities.

Selling, general and administrative

Quarterly

Selling, general and administrative ("SG&A") expenses decreased $0.2 million, or 0%, during the third quarter of fiscal 2020 compared to the same quarter one year ago. The decrease was primarily due to $4.3 million lower other variable spending and $1.6 million lower spending on headcount partially offset by $4.1 million higher stock-based compensation expense, the impact of a benefit of $1.3 million from amounts received in third quarter of fiscal 2019 on a resolved asset recovery matter and $0.3 million higher charges for increases in deferred compensation plan liabilities. The $4.3 million in lower variable spending included lower travel and other variable discretionary spending due to COVID-19, lower provisions for bad debts, lower depreciation expense due to the impairment of ILS long-lived assets in the second quarter of fiscal 2020, lower spending on sales rep commissions and the favorable impact of foreign exchange rates partially offset by higher audit and consulting spending on special projects. The $1.6 million lower spending on headcount was primarily due to lower severance and restructuring costs, the impact of lower headcount and the favorable impact of foreign exchange rates partially offset by the impact of one extra week in the second quarter of fiscal 2020 and higher costs related to the transition of our former CEO to special advisor status. The $4.1 million higher stock-based compensation expense is primarily due to the acceleration of the accounting charges for equity grants for our former CEO and increased grants to employees.

On a segment basis as compared to the prior year period, OLS SG&A expenses decreased $4.4 million primarily due to lower variable spending on travel, sales rep commissions and other discretionary spending as well as the favorable impact of foreign exchange rates partially offset by higher headcount spending including higher sales commissions. ILS SG&A spending decreased $2.1 million primarily due to lower headcount spending including lower severance and the impact of lower

headcount, lower variable spending on sales rep commissions, travel, depreciation and bad debts as well as the favorable impact of foreign exchange rates partially offset by the prior year resolved asset recovery matter. Corporate and other SG&A spending increased $6.3 million primarily due to higher stock-based compensation expense, higher audit and consulting fees, higher costs related to the transition of our former CEO to special advisor status and higher charges for the deferred compensation plan.

Year-to-date

Selling, general and administrative ("SG&A") expenses decreased $4.3 million, or 2%, during the first nine months of fiscal 2020 compared to the same period one year ago. The decrease was primarily due to $7.5 million lower variable spending and $2.3 million lower spending on headcount. The decreases were partially offset by $4.1 million higher stock-based compensation expense primarily due to the acceleration of the accounting charges for equity grants for our former CEO and increased grants to employees and $1.4 million higher charges for increases in deferred compensation plan liabilities. The $7.5 million lower variable spending included lower spending on travel and other variable discretionary spending due to COVID-19, lower sales rep commissions, lower provisions for bad debts, lower depreciation expense due to the impairment of ILS long-lived assets in the second quarter of fiscal 2020 and the favorable impact of foreign exchange rates, partially offset by higher audit and consulting spending on special projects. The $2.3 million lower spending on headcount was primarily due to lower sales commissions, lower severance, the impact of lower headcount and the favorable impact of foreign exchange rates partially offset by the impact of one extra week in the second quarter of fiscal 2020 and higher costs related to the retirement of our former CEO.

On a segment basis as compared to the prior year period, OLS SG&A expenses decreased $1.6 million primarily due to lower variable spending including travel, sales rep commissions and other discretionary spending and as well as the favorable impact of foreign exchange rates partially offset higher headcount spending. ILS SG&A spending decreased $11.1 million primarily due to lower variable spending (including lower spending on travel and other variable discretionary spending due to COVID-19, lower sales rep commissions, lower provisions for bad debts and lower depreciation expense), lower spending on headcount (lower severance and the impact of lower headcount net of the impact of one extra week in the second quarter of fiscal 2020) and the favorable impact of foreign exchange rates. Corporate and other SG&A spending increased $8.4 million primarily due to higher stock-based compensation expense, higher headcount spending including higher costs related to the retirement of our former CEO, higher charges for the deferred compensation plan and higher audit and consulting fees.

Goodwill and other impairment charges
Year-to-date
In the second quarter of fiscal 2020, we recorded non-cash pre-tax goodwill impairment charges of $327.2 million related to our ILS segment to operating expense in our results of operations. In addition, we recorded non-cash pre-tax charges related to the impairment of intangible assets, property, plant and equipment and ROU assets of the ILS reporting unit of $33.9 million, $85.6 million and $1.8 million, respectively. See Note 8, "Goodwill and Intangible Assets" in the Notes to Condensed Consolidated Financial Statements and Note 11, "Leases" in the Notes to Condensed Consolidated Financial Statements.
In the first quarter of fiscal 2019, we invested 3.0 million Euros ($3.4 million) in 3D-Micromac AG, a private company in Germany. The investment is included in other assets and is being carried on a cost basis. During the second quarter of fiscal 2020, we determined that our investment became impaired and wrote it down to its fair value. As a result, we recorded a non-cash impairment charge of $2.5 million to operating expense in our results of operations in the second quarter of fiscal 2020.
Amortization of intangible assets
 
Amortization of intangible assets decreased $6.1 million and $8.4 million, respectively, in the three and nine months ended July 4, 2020 compared to the same periods last year. The decreases were primarily due to the impairment of ILS intangibles in the second quarter of fiscal 2020, the completion of the amortization of certain intangibles from acquisitions and the favorable impact of foreign exchange rates.

OTHER INCOME (EXPENSE) — NET
 
Other income (expense), net, changed by $0.1 million to an expense of $4.3 million in the third quarter of fiscal 2020 from an expense of $4.4 million in the third quarter of fiscal 2019. Other income (expense), net, changed by $4.8 million to an expense of $13.0 million in the first nine months of fiscal 2020 from an expense of $17.8 million in the first nine months of fiscal 2019.

The third fiscal quarter decrease in net other expense was primarily due to $0.9 million lower interest expense and $0.6 million higher gains (lower losses), net of expenses, on our deferred compensation plan assets partially offset by $1.1 million higher

foreign exchange losses. Interest expense decreased primarily due to lower interest expense on line of credit borrowings and lower amortization of bond issue costs related to our Euro senior secured term loan facility (the "Euro Term Loan") partially offset by higher interest on the Euro Term Loan.

The decrease for the first nine months of fiscal 2020 in net other expense was primarily due to $2.4 million higher gains (lower losses), net of expenses, on our deferred compensation plan assets, $2.2 million lower interest expense and $1.8 million lower foreign exchange losses partially offset by $1.7 million lower benefit from non-service pension income. Interest expense decreased primarily due to lower amortization of bond issue costs related to our Euro senior secured term loan facility (the "Euro Term Loan") and lower interest expense on line of credit borrowings partially offset by higher interest on the Euro Term Loan.

INCOME TAXES  

Our effective tax rate on loss before income taxes for the three and nine months ended July 4, 2020 reflected a provision at a 59.6% rate and a benefit at a 6.9% rate, respectively. Our effective tax rate for the three months ended July 4, 2020 was unfavorably impacted primarily due to the establishment of valuation allowances for certain deferred tax assets. Our effective tax rate for the nine months ended July 4, 2020 was unfavorably impacted primarily due to the impairment of goodwill that is not deductible for tax purposes and the establishment of valuation allowances for certain deferred tax assets. These unfavorable impacts were partially offset by the release of unrecognized tax benefits net of settlements and competent authority offsets, the geographic distribution of the impairments of certain long-lived assets that are deductible for tax purposes and the reduction in foreign earnings subject to foreign tax rates that are higher than the U.S. tax rates. Our effective tax rate is based on forecasted annual results and these amounts may fluctuate significantly through the rest of the year as a result of the unpredictable impact of COVID-19 on our operating activities.

Our effective tax rate on income (loss) before income taxes for the three and nine months ended June 29, 2019 was a benefit at a 73.2% rate and a provision at a 6.2% rate, respectively. Our effective tax rate for the three months ended June 29, 2019 reflected the recognition of a tax benefit on a pre-tax loss. This loss was in part a result of the restructuring costs in the third quarter of fiscal 2019 in our German operations resulting from our decision to relocate the manufacturing and engineering of our HPFL products at our Hamburg, Germany facility to our Tampere, Finland location and exit a portion of our HPFL business. A benefit in a high tax jurisdiction increases the effective tax rate on a loss. Furthermore, revision of the estimated annual effective tax rate in the third quarter of fiscal 2019 resulted in additional benefit to the period and cumulatively offset tax expense recorded through the previous quarter. Our effective tax rate for the nine months ended June 29, 2019 was lower than the U.S. federal tax rate of 21.0% primarily due to the tax benefit from German losses subject to higher tax rates than U.S. tax rates, the excess tax benefits from restricted stock unit vesting, the benefit of federal research and development tax credits and our Singapore and South Korea tax exemptions. These amounts were partially offset by an accrual for foreign withholding taxes on certain current year foreign earnings not considered permanently reinvested, stock-based compensation not deductible for tax purposes and limitations on the deductibility of compensation under IRC Section 162(m).

LIQUIDITY AND CAPITAL RESOURCES
 
At July 4, 2020, we had assets classified as cash and cash equivalents and short-term investments, in an aggregate amount of $420.9 million, compared to $306.0 million at September 28, 2019. In addition, at July 4, 2020, we had $5.2 million of restricted cash. At July 4, 2020, approximately $296.0 million of our cash and securities was held in certain of our foreign subsidiaries and branches, $273.3 million of which was denominated in currencies other than the U.S. dollar. Cash held by foreign subsidiaries includes cash in certain entities where we intend to permanently reinvest our accumulated earnings and our current plans do not demonstrate a need for these funds to support our domestic operations. If, however, a portion of these funds are needed for and distributed to our operations in the United States, we may be subject to additional foreign withholding taxes and certain state taxes. The amount of the U.S. and foreign taxes due would depend on the amount and manner of repatriation, as well as the location from where the funds are repatriated. We historically asserted our intention to indefinitely reinvest foreign earnings. In December 2017, we reevaluated our assertion as a result of the enactment of the Tax Act and no longer consider certain foreign earnings to be indefinitely reinvested in our foreign subsidiaries. We actively monitor the third-party depository institutions that hold these assets, primarily focusing on the safety of principal and secondarily maximizing yield on these assets. We diversify our cash and cash equivalents and investments among various financial institutions, money market funds, sovereign debt and other securities in order to reduce our exposure should any one of these financial institutions or financial instruments fail or encounter difficulties. To date, we have not experienced any material loss or lack of access to our invested cash, cash equivalents or short-term investments. However, we can provide no assurances that access to our invested cash, cash equivalents or short-term investments will not be impacted by adverse conditions in the financial markets. To date, we have had sufficient liquidity to manage the financial impact of COVID-19. However, we can provide no assurance that this will continue to be the case if the impact of COVID-19 is prolonged or if there is an extended impact on us or the economy in

general. Further, COVID-19 has caused significant uncertainty and volatility in the credit markets. If our liquidity or access to capital becomes significantly constrained, or if costs of capital increase significantly due to the impact of COVID-19 as result of a volatility in the capital markets, a reduction in our creditworthiness or other factors, then our financial condition, results of operations and cash flows could be materially adversely affected.

See "Part I, Item 3. Quantitative and Qualitative Disclosures About Market Risk" below for more information about risks and trends related to foreign currencies.

Sources and Uses of Cash
 
Historically, our primary source of cash has been provided by our operations. Other sources of cash in the past few fiscal years include proceeds from our Euro Term Loan used to finance our acquisition of Rofin, proceeds received from the sale of our stock through our employee stock purchase plan as well as borrowings under our revolving credit facility ("Revolving Credit Facility"). Our historical uses of cash have primarily been for acquisitions of businesses and technologies, the repurchase of our common stock, capital expenditures and debt issuance costs. Supplemental information pertaining to our historical sources and uses of cash is presented as follows and should be read in conjunction with our condensed consolidated statements of cash flows and the notes to condensed consolidated financial statements:

Borrowings (repayments), net (7,180)   32,648   
Purchases of property and equipment (48,436)   (60,511)  
 
Net cash provided by operating activities increased by $24.7 million for the first nine months of fiscal 2020 compared to the same period one year ago. The increase in cash provided by operating activities was primarily due to higher cash flows from deferred taxes, taxes payable and accounts payable partially offset by lower net income (net of non-cash adjustments). In order to support our liquidity during the pandemic, we are proactively taking measures to increase available cash on hand, including, but not limited to, reducing discretionary spending for operating and capital expenses. To further support our liquidity, we have elected to defer the payment of our employer portion of social security taxes beginning in April 2020 and through the end of the calendar year, which we expect to pay in equal installments in the first quarters of fiscal 2022 and 2023, as provided for under the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"). We are also taking advantage of the retention credit of the CARES Act for employees who are idled as a result of COVID-19. We believe that our existing cash, cash equivalents and short term investments combined with cash to be provided by operating activities and amounts available under our Revolving Credit Facility will be adequate to cover our working capital needs and planned capital expenditures for at least the next 12 months to the extent such items are known or are reasonably determinable based on current business and market conditions, including consideration of the impact of COVID-19. However, we may elect to finance certain of our capital expenditure requirements through other sources of capital. We continue to follow our strategy to further strengthen our financial position by using available cash flow to fund operations.

We intend to continue to consider acquisition opportunities at valuations we believe are reasonable based upon market conditions. However, we cannot accurately predict the timing, size and success of our acquisition efforts or our associated potential capital commitments. Furthermore, we cannot assure you that we will be able to acquire businesses on terms acceptable to us. We expect to fund future acquisitions, if any, through existing cash balances and cash flows from operations (as in our acquisitions of Ondax and certain Quantum assets) and additional borrowings (as in our acquisition of Rofin). If required, we will consider the issuance of securities. The extent to which we will be willing or able to use our common stock to make acquisitions will depend on its market value at the time and the willingness of potential sellers to accept it as full or partial payment.

In fiscal 2019, we made debt principal payments of $7.5 million, recorded interest expense on the Euro Term Loan of $11.7 million and recorded $4.6 million amortization of debt issuance costs. On November 20, 2018, we borrowed an additional $40.0 million under our Revolving Credit Facility, subsequently repaid $30.0 million of these borrowings on July 29, 2019 and recorded interest expense related to it of $1.9 million in fiscal 2019.

In the first nine months of fiscal 2020, we made debt principal payments of $5.6 million, recorded interest expense on the Euro Term Loan of $9.1 million and recorded $2.5 million amortization of debt issuance costs. In the first nine months of fiscal 2020, we recorded interest expense related to our Revolving Credit Facility of $0.4 million.

On October 5, 2018, we acquired privately held Ondax for approximately $12.0 million, excluding transaction costs. On October 5, 2018, we acquired certain assets of Quantum Coating, Inc. for approximately $7.0 million, excluding transaction costs.

On October 28, 2018, our board of directors authorized a stock repurchase program authorizing the Company to repurchase up to $250.0 million of our common stock through December 31, 2019, with a limit of no more than $75.0 million per quarter. During fiscal 2019, we repurchased and retired 603,828 shares of outstanding common stock under this program at an average price of $128.20 per share for a total of $77.4 million. We made no repurchases under the program during fiscal 2020 and the program expired on December 31, 2019. On February 5, 2020, our board of directors authorized a stock repurchase program authorizing the Company to repurchase up to $100.0 million of our common stock through January 31, 2021. We have made no repurchases under the program during fiscal 2020. See Note 14, "Stock Repurchases" in the Notes to Condensed Consolidated Financial Statements.

Additional sources of cash available to us, in addition to the amounts available under the Revolving Credit Facility, were international currency lines of credit and bank credit facilities totaling $16.4 million as of July 4, 2020, of which $13.5 million was unused and available. These unsecured international credit facilities were used in Europe and Japan during the first nine months of fiscal 2020. As of July 4, 2020, we had utilized $2.9 million of the international credit facilities as guarantees in Europe.
 
Our ratio of current assets to current liabilities decreased to 4.4:1 at July 4, 2020 compared to 4.6:1 September 28, 2019. The decrease in our ratio was primarily due to higher accounts payable, lower accounts receivable and lease liabilities recorded as a result of the adoption of ASC 842 partially offset by increases in our ratio due to higher cash and cash-equivalents and lower other current liabilities. Our cash and cash equivalents, short-term investments and working capital are as follows:

Contractual Obligations and Off-Balance Sheet Arrangements
We have no off-balance sheet arrangements as defined under Regulation S-K of the Securities Act of 1933. Information regarding our contractual obligations is provided in Item 7 "Management’s Discussion and Analysis of Financial Condition and Results of Operations" of our Annual Report on Form 10-K for the fiscal year ended September 28, 2019. There have been no material changes in contractual obligations outside of the ordinary course of business since September 28, 2019. Information regarding our other financial commitments at July 4, 2020 is provided in the Notes to Condensed Consolidated Financial Statements in this report.

Changes in Financial Condition
 
Cash provided by operating activities during the first nine months of fiscal 2020 was $160.1 million, which included non-cash goodwill and other impairment charges of $451.0 million, depreciation and amortization of $63.4 million, stock-based compensation expense of $31.1 million, cash provided by operating assets and liabilities of $39.9 million (primarily lower accounts receivable and higher accounts payable net of lower income taxes payable and payments made for lease liabilities), amortization of operating ROU assets of $12.1 million, amortization of debt issuance cost of $2.5 million and non-cash restructuring charges of $2.1 million partially offset by net loss of $421.8 million and net increases in deferred tax assets of $21.8 million.

included depreciation and amortization of $89.2 million, net income of $53.2 million, stock-based compensation expense of $26.5 million, non-cash restructuring charges of $12.1 million and amortization of debt issuance cost of $3.8 million partially offset by cash used by operating assets and liabilities of $38.8 million (primarily lower income taxes payable, accrued payroll, customer deposits and customer deposits and deferred income, net of lower accounts receivable) and net increases in deferred tax assets of $8.2 million.

Cash used in investing activities during the first nine months of fiscal 2020 was $89.5 million, which included $47.8 million, net of proceeds from dispositions, used to acquire property and equipment and purchase and upgrade buildings and $41.8 million net purchases of available-for-sale securities. Cash used in investing activities during the first nine months of fiscal 2019 was $79.6 million, which included $55.3 million, net of proceeds from dispositions, used to acquire property and equipment and purchase and upgrade buildings, $18.9 million, net of cash acquired, to purchase Ondax and Quantum, $3.4 million invested in 3D-Micromac AG and $2.0 million net purchases of available-for-sale securities.
 
Cash used in financing activities during the first nine months of fiscal 2020 was $7.3 million, which included $13.5 million in outflows due to net settlement of restricted stock units and $7.2 million net debt payments partially offset by $13.4 million generated from our employee stock option and purchase plans. Cash used in financing activities during the first nine months of fiscal 2019 was $48.1 million, which included $77.4 million used to repurchase shares of our common stock and $15.2 million in outflows due to net settlement of restricted stock units partially offset by $32.6 million net debt borrowings and $11.8 million generated from our employee stock option and purchase plans.

Changes in exchange rates during the first nine months of fiscal 2020 resulted in an increase in cash balances of $2.4 million. Changes in exchange rates during the first nine months of fiscal 2019 resulted in a decrease in cash balances of $1.9 million.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
Market risk disclosures
 
We are exposed to market risk related to changes in interest rates and foreign currency exchange rates. We do not use derivative financial instruments for speculative or trading purposes.
 
Interest rate sensitivity
 
A portion of our investment portfolio is composed of fixed income securities. These securities are subject to interest rate risk and will fall in value if market interest rates increase. If market interest rates were to increase immediately (whether due to changes in overall market rates or credit worthiness of the issuers of our individual securities) and uniformly by 10% from levels at July 4, 2020, the fair value of the portfolio, based on quoted market prices in active markets involving similar assets, would decline by an immaterial amount due to their short-term maturities. We have the ability to generally hold our fixed income investments until maturity and therefore we would not expect our operating results or cash flows to be affected to any significant degree by the effect of a sudden change in market interest rates on our securities portfolio. If necessary, we may sell short-term investments prior to maturity to meet our liquidity needs.
 
At July 4, 2020, the fair value of our available-for-sale debt securities was $0.1 million, all of which was classified short-term investments.

We are exposed to market risks related to fluctuations in interest rates related to our Euro Term Loan. As of July 4, 2020, we owed $405.9 million on this loan with an interest rate of 3.0%. We performed a sensitivity analysis on the outstanding portion of our debt obligation as of July 4, 2020. Should the current average interest rate increase or decrease by 10%, the resulting annual increase or decrease to interest expense would be approximately $1.2 million as of July 4, 2020.

Foreign currency exchange risk

We maintain operations in various countries outside of the United States and have foreign subsidiaries that manufacture and sell our products in various global markets. The majority of our sales are transacted in U.S. dollars. However, we do generate revenues in other currencies, primarily the Euro, the Japanese Yen, the South Korean Won, the Singapore Dollar and the Chinese Renminbi. Additionally we have operations in different countries around the world with costs incurred in the foregoing currencies and other local currencies, such as British Pound Sterling, Malaysian Ringgit, Swiss Franc, Taiwan Dollar, Swedish Krona, Canadian Dollar and Vietnamese Dong. As a result, our earnings, cash flows and cash balances are exposed to fluctuations in foreign currency exchange rates. For example, because of our significant manufacturing operations in Europe, a weakening Euro is advantageous and a strengthening Euro is disadvantageous to our financial results. We attempt to limit these exposures through financial market instruments. We utilize derivative instruments, primarily forward contracts with maturities of two months or less, to manage our exposure associated with anticipated cash flows and net asset and liability positions denominated in foreign currencies. Gains and losses on the forward contracts are mitigated by gains and losses on the underlying instruments. We do not use derivative financial instruments for trading purposes.
 
We do not anticipate any material adverse effect on our condensed consolidated financial position, results of operations or cash flows resulting from the use of these instruments. There can be no assurance that these strategies will be effective or that transaction losses can be minimized or forecasted accurately. While we model currency valuations and fluctuations, these may not ultimately be accurate. If a financial counterparty to any of our hedging arrangements experiences financial difficulties or is otherwise unable to honor the terms of the foreign currency hedge, we may experience material financial losses. In the current economic environment, the risk of failure of a financial party remains high.

A hypothetical 10% change in foreign currency rates on our forward contracts would not have a material impact on our results of operations, cash flows or financial position.

At July 4, 2020, approximately $296.0 million of our cash, cash equivalents and short-term investments were held outside the U.S. in certain of our foreign operations, $273.3 million of which was denominated in currencies other than the U.S. dollar.

ITEM 4. CONTROLS AND PROCEDURES
 
Management’s Evaluation of Disclosure Controls and Procedures
 
We have evaluated the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as of July 4, 2020 ("Evaluation Date"). The controls evaluation was conducted under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded as of the Evaluation Date that our disclosure controls and procedures were effective in providing reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Securities Exchange Act of 1934, as amended, is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.
 
Changes in Internal Control over Financial Reporting
 
There were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting during the three months ended July 4, 2020.

Inherent Limitations over Internal Control
 
Management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of internal controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Also, any evaluation of the effectiveness of controls in future periods are subject to the risk that those internal controls may become inadequate because of changes in business conditions, or that the degree of compliance with the policies or procedures may deteriorate.

ITEM 1. LEGAL PROCEEDINGS

Information with respect to this item may be found in Note 13, "Commitments and Contingencies" in the Notes to Condensed Consolidated Financial Statements in Part I, Item 1 of this report and is incorporated herein by reference.

ITEM 1A. RISK FACTORS

You should carefully consider the followings risks when considering an investment in our common stock. These risks could materially affect our business, results of operations or financial condition, cause the trading price of our common stock to decline materially or cause our actual results to differ materially from those expected or those expressed in any forward-looking statements made by us. These risks are not exclusive, and additional risks to which we are subject include, but are not limited to, the factors mentioned under "Forward-Looking Statements" of our Annual Report on Form 10-K for the fiscal year ended September 28, 2019 and the risk of our businesses described elsewhere in this quarterly report. Additionally, these risks and uncertainties described herein are not the only ones facing us. Other events that we do not currently anticipate or that we currently deem immaterial also may affect our business, results of operations or financial condition.

Our operating results, including net sales, net income (loss) and adjusted EBITDA in dollars and as a percentage of net sales, as well as our stock price have varied in the past, and our future operating results will continue to be subject to quarterly and annual fluctuations based upon numerous factors, including those discussed in this Item 1A and throughout this report. Our stock price will continue to be subject to daily variations as well. Our future operating results and stock price may not follow any past trends or meet our guidance and expectations.
 
Our net sales and operating results, such as operating expenses, adjusted EBITDA percentage, net income (loss) and our stock price have varied in the past and may vary significantly from quarter to quarter and from year to year in the future. We believe a number of factors, many of which are outside of our control, could cause these variations and make them difficult to predict, including:

general economic uncertainties in the macroeconomic and local economies facing us, our customers and the markets we serve, particularly as the novel coronavirus ("COVID-19") pandemic continues to adversely affect the global economy;

impact of government economic policies on macroeconomic conditions, such as recently instituted, proposed or threatened changes in trade policies by the U.S. and any corresponding retaliatory actions by affected countries, in particular with respect to China, and trade restrictions the Japanese government has recently instituted affecting the export to South Korea of certain products and materials used in the manufacture of flat panel displays and in the semiconductor industry;

negative impacts related to the United Kingdom's withdrawal from the European Union, or "Brexit" including uncertainties regarding the terms of applicable trade treaties between the United Kingdom and other countries, particularly with regard to any potential negative effects on our sales from our Glasgow, Scotland facility to other jurisdictions and purchases of supplies from outside the United Kingdom by such facility;

negative impacts related to the recent independence movement in Catalonia, Spain, particularly with regard to holding and operating some of our foreign entities in an efficient manner from a tax, business and legal perspective;

negative impacts related to government instability in any jurisdiction in which we operate, such as the recent difficulties in forming a governing coalition in Germany;

the future impact of legislation, rulemaking, and changes in accounting, tax, defense procurement and export policies; and

distraction of management related to acquisition, integration or divestment activities.

In addition, we often recognize a substantial portion of our sales in the last month of our fiscal quarters. Our expenses for any given quarter are typically based on expected sales, and if sales are below expectations in any given quarter, the adverse impact of the shortfall on our operating results may be magnified by our inability to adjust spending quickly enough to compensate for the shortfall. We also base our manufacturing on our forecasted product mix for the quarter. If the actual product mix varies significantly from our forecast, we may not be able to fill some orders during that quarter, which would result in delays in the shipment of our products. Accordingly, variations in timing of sales, particularly for our higher priced, higher margin products, can cause significant fluctuations in quarterly operating results.
55

Table of Contents

Due to these and other factors, we believe that quarter-to-quarter and year-to-year comparisons of our historical operating results may not be meaningful. You should not rely on our results for any quarter or year as an indication of our future performance. Our operating results in future quarters and years may be below public market analysts' or investors' expectations, which would likely cause the price of our stock to fall. In addition, over the past several years, U.S. and global equity markets have experienced significant price and volume fluctuations that have affected the stock prices of many technology companies both in and outside our industry, and the ongoing COVID-19 pandemic could exacerbate such fluctuations. There has not always been a direct correlation between this volatility and the performance of particular companies subject to these stock price fluctuations. These factors, as well as general economic and political conditions or investors' concerns regarding the credibility of corporate financial statements, may have a material adverse effect on the market price of our stock in the future.

Our business, financial condition and results of operations for fiscal year 2020 and beyond may be materially adversely affected by the COVID-19 pandemic.

The full extent to which COVID-19 will impact our financial condition and operating results will depend on future developments that are highly uncertain and cannot be accurately predicted, including COVID-19 infections intensifying or returning in various geographic areas as is currently happening in the United States, new medical and other information that may emerge concerning COVID-19, and the actions by governmental entities or others to address it, contain it or treat its impact.

COVID-19 poses the risk that we or our employees, suppliers, distributors, customers and others may be restricted or prevented from conducting business activities for indefinite or intermittent periods of time, including as a result of employee health and safety concerns, shutdowns, shelter-in-place ("SiP") orders, travel restrictions and other actions and restrictions that may be prudent or required by governmental authorities. Even after governmental entities have lifted SiP orders, there is a risk that such orders will be reinstated in jurisdictions in the short and long term, making it difficult to predict the longer term financial impact of this virus on the Company.

To date, many (but not all) of our business operations and those of our suppliers, distributors and customers have been classified as essential or otherwise permitted to operate in jurisdictions in which facility closures have been mandated; however, we can give no assurance that this will not change in the future or that we, our suppliers, distributors and customers will continue to be permitted to conduct business in each of the jurisdictions in which we operate.

In addition, we have modified our business practices for the continued health and safety of our employees - including, among other things, implementing a remote work policy to the fullest extent possible, a limited travel policy and a social distancing policy - and we may take further actions, or be required to take further actions, that are in the best interests of our employees. Our suppliers, distributors and customers have also implemented such measures, which has resulted in, and we expect it will continue to result in, disruptions or delays and higher costs. The implementation of health and safety practices by us, our suppliers, distributors or our customers could impact customer demand, supplier deliveries, our productivity, and costs, which could have a material adverse impact on our business, financial condition, or results of operations.

While we currently believe we have sufficient liquidity to manage the financial impact of the COVID-19 pandemic, we can give no assurance that this will continue to be the case if the pandemic is prolonged or if there is an extended impact on us or the economy generally. Further, the pandemic has caused significant uncertainty and volatility in the credit markets. If our liquidity or access to capital becomes significantly constrained, or if costs of capital increase significantly as result of volatility in the capital markets, a reduction in our creditworthiness or other factors, then our financial condition, results of operations and cash flows could be materially adversely affected.

We have invested and will continue to invest significant time and resources in managing the impact of the COVID-19 pandemic on our business. Our focus on managing and mitigating such impact may cause us to divert or delay the application of resources toward existing or new initiatives or investments, which could have a material adverse impact on our results of operations.

Please refer to “Coronavirus pandemic (COVID-19)” under “Significant Events” “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” for additional discussion of the risks related to COVID-19 and its impact on the company.

We depend on sole source or limited source suppliers, as well as on our own production capabilities, for some of the key components and materials, including exotic materials, certain cutting-edge optics and crystals, used in our products, which
56

Table of Contents
make us susceptible to supply shortages or price fluctuations that could adversely affect our business, particularly our ability to meet our customers' delivery requirements.

We currently purchase several key components and materials used in the manufacture of our products from sole source or limited source suppliers. In particular, from time-to-time our customers require us to ramp up production and/or accelerate delivery schedules of our products. Our key suppliers may not have the ability to increase their production in line with our customers' demands. This can become acute during times of high growth in our customers' businesses. Our failure to timely receive these key components and materials would likely cause delays in the shipment of our products, which would likely negatively impact both our customers and our business. Some of these suppliers are relatively small private companies that may discontinue their operations at any time and which may be particularly susceptible to prevailing economic conditions. Some of our suppliers are located in regions which may be susceptible to natural and man-made disasters, such as the flooding in Thailand and the earthquake, tsunami and resulting nuclear disaster in Japan and severe flooding and power loss in the Eastern part of the United States and in California. In addition, our suppliers have been adversely affected by the COVID-19 pandemic and the related imposition of government restrictions to mitigate the spread of the virus. We typically purchase our components and materials through purchase orders or agreed upon terms and conditions, and we do not have guaranteed supply arrangements with many of these suppliers. For certain long-lead time supplies or in order to lock-in pricing, we may be obligated to place non-cancellable purchase orders or otherwise assume liability for a large amount of the ordered supplies, which limits our ability to adjust down our inventory liability in the event of market downturns or other customer cancellations or rescheduling of their purchase orders for our products.

Some of our products, particularly in the flat panel display industry, require designs and specifications that are at the cutting-edge of available technologies and change frequently to meet rapidly evolving market demands. By their very nature, the types of components used in such products can be difficult and unpredictable to manufacture and may only be available from a single supplier, which increases the risk that we may not obtain such components in a timely manner. Identifying alternative sources of supply for certain components could be difficult and costly, result in management distraction in assisting our current and future suppliers to meet our and our customers' technical requirements, and cause delays in shipments of our products while we identify, evaluate and test the products of alternative suppliers. Any such delay in shipment would result in a delay or cancellation of our ability to convert such order into revenues. Furthermore, financial or other difficulties faced by these suppliers or significant changes in demand for these components or materials could limit their availability. We continue to consolidate our supply base and move supplier locations. When we transition locations, we may increase our inventory of such products as a "safety stock" during the transition, which may cause the amount of inventory reflected on our balance sheet to increase. Additionally, many of our customers rely on sole source suppliers. In the event of a disruption of our customers' supply chain, orders from our customers could decrease or be delayed.

Like most other multinational companies, we are also highly dependent upon the ability to ship products to customers and to receive shipments of supplies from suppliers. The COVID-19 pandemic and resulting government policies have resulted in variable limitations on our ability to receive supplies and to ship our products to customers. In the event of a disruption in the worldwide or regional shipping infrastructure, our access to supplies and our ability to deliver products to customers would correspondingly be negatively impacted. Any such disruption would likely materially and adversely affect our operating results and financial condition.

Any interruption or delay in the supply of any of these components or materials, or the inability to obtain these components and materials from alternate sources at acceptable prices and within a reasonable amount of time, or our failure to properly manage these moves, would impair our ability to meet scheduled product deliveries to our customers and could cause customers to cancel orders. Furthermore, we have historically relied exclusively on our own production capability to manufacture certain strategic components, crystals, semiconductor lasers, fiber, lasers and laser-based systems. We also manufacture certain large format optics. Because we manufacture, package and test these components, products and systems at our own facilities, and such components, products and systems are not readily available from other sources, any interruption in manufacturing would adversely affect our business. Since many of our products have lengthy qualification periods, our ability to introduce multiple suppliers for parts may be limited. In addition, our failure to achieve adequate manufacturing yields of these items at our manufacturing facilities may materially and adversely affect our operating results and financial condition.

We participate in the microelectronics market, which requires significant research and development expenses to develop and maintain products and a failure to achieve market acceptance for our products could have a significant negative impact on our business and results of operations.

The microelectronics market is characterized by rapid technological change, frequent product introductions, the volatility of product supply and demand, changing customer requirements and evolving industry standards. The nature of this market requires significant research and development expenses to participate, with substantial resources invested in advance of material sales of our products to our customers in this market. Additionally, our product offerings may become obsolete given the frequent introduction of alternative technologies. In the event either our customers' or our products fail to gain market acceptance, or the microelectronics market fails to grow, it would likely have a significant negative effect on our business and results of operations.

We participate in the flat panel display market, which has a relatively limited number of end customer manufacturers. Our backlog, timing of net sales and results of operations could be negatively impacted in the event we face any significant periods with few or no orders or our customers reschedule or cancel orders.

In the flat panel display market it is unclear when the timing will be, or whether it will occur at all, for any further build-out of fabs for the manufacture of OLED screens and there are a relatively limited number of manufacturers who are the end customers for our annealing products. In the third quarter of fiscal 2020, Advanced Process Systems Corporation, an integrator in the flat panel display market based in South Korea, contributed more than 10% of our revenue. Given macroeconomic conditions, varying consumer demand and technical process limitations at manufacturers, we may see fluctuations in orders, including periods with no or few orders, and our customers may seek to reschedule or cancel orders. For example, in the fourth quarter of fiscal 2018, a customer requested a change of delivery date resulting in a significant order being rescheduled from the first to the second quarter of fiscal 2019. In addition, in the first quarter of fiscal 2019, one customer cancelled three purchase orders which included backlog shippable within 12 months of $38.2 million as well as some additional orders which were unscheduled.

These larger flat panel-related systems have large average selling prices. Any significant periods with few or no orders or any rescheduling or canceling of such orders by our customers will likely have a significant impact on our quarterly or annual net sales and results of operations and could negatively impact inventory values and backlog. Additionally, challenges in meeting evolving technological requirements for these complex products by us and our suppliers could also result in delays in shipments and rescheduled or cancelled orders by our customers. This could negatively impact our backlog, timing of net sales and results of operations.

We may not be able to integrate the business of Rofin successfully with our own, realize the anticipated benefits of the merger or manage our expanded operations, any of which would adversely affect our results of operations.

We have devoted, and expect to continue to devote, significant management attention and resources to integrating our business practices with those of Rofin. Such integration efforts are costly due to the large number of processes, policies, procedures, locations, operations, technologies and systems to be integrated, including purchasing, accounting and finance, sales, service, operations, payroll, pricing, marketing and employee benefits. Integration expenses could, particularly in the short term, exceed the savings we expect to achieve from the elimination of duplicative expenses and the realization of economies of scale, which could result in significant charges to earnings that we cannot currently quantify. Potential difficulties that we may encounter as part of the integration process include the following:

the inability to successfully combine our business with Rofin in a manner that permits the combined company to achieve the full synergies and other benefits anticipated to result from the merger;

complexities associated with managing the combined businesses, including difficulty addressing possible differences in corporate cultures and management philosophies and the challenge of integrating products, services, complex and different information technology systems (including different Enterprise Management Systems), control and compliance processes, technology, networks and other assets of each of the companies in a cohesive manner;

diversion of the attention of our management;

the disruption of, or the loss of momentum in, our business; and

inconsistencies in standards, controls, procedures or policies.

58

Table of Contents
Any of the foregoing could adversely affect our ability to maintain relationships with customers, suppliers, employees and other constituencies or our ability to achieve the anticipated benefits of the merger, or could reduce our earnings or otherwise adversely affect our business and financial results. For example, in the fourth quarter of fiscal 2018, difficulties in implementing our Enterprise Management Systems at one of our manufacturing sites located in Germany, which was historically part of Rofin, resulted in a shortage of manufacturing parts and shippable inventory to meet demands, resulting in a reduction of revenue for that quarter. If similar difficulties arise in the future and we are unable to resolve them in a timely manner, we may experience a shortage of parts and inventory or otherwise be unable to meet demand, which could have a material adverse impact on our results of operations.

Following the merger, the size and complexity of the business of the combined company has increased significantly. Our future success depends, in part, upon our ability to manage this expanded business, which has and will pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. The execution of these consolidation projects could result in temporary loss of productivity or operational efficiency, interruptions in manufacturing or other unforeseen challenges while the projects are ongoing. Moreover, there can be no assurances that we will be successful in realizing the anticipated savings in connection with these consolidations or with our broader efforts to manage our expanded business or that we will realize the expected synergies and benefits anticipated from the merger.

Charges to earnings resulting from the application of the purchase method of accounting to the Rofin acquisition may adversely affect our results of operations.

In accordance with generally accepted accounting principles, we have accounted for the Rofin acquisition using the purchase method of accounting. Under the purchase method of accounting, we allocated the total purchase price of Rofin's net tangible and identifiable intangible assets based upon their estimated fair values at the acquisition date. The excess of the purchase price over net tangible and identifiable intangible assets was recorded as goodwill. We have incurred and will continue to incur additional depreciation and amortization expense over the useful lives of certain of the net tangible and intangible assets acquired in connection with the acquisition. These depreciation, amortization and potential impairment charges could have a material impact on our results of operations. In addition, to the extent the value of goodwill or intangible assets with indefinite lives becomes impaired, we may be required to incur material charges relating to the impairment of those assets. For example, in the quarter ended April 4, 2020, the worldwide spread of COVID-19 created significant volatility, uncertainty and disruption to the global economy, representing an indicator to test our goodwill for impairment. The former operations of Rofin are largely included in our ILS segment. As a result of that test, we recorded a non-cash pre-tax charge, in the quarter ended April 4, 2020, related to the ILS reporting unit of $327.2 million, reducing the goodwill balance of the reporting unit to zero. In addition, we performed impairment tests on the long-lived assets allocated to the asset group of the ILS reporting unit, including intangible assets, property, plant and equipment and right-of-use ("ROU") assets as of April 4, 2020 and recorded non-cash pre-tax charges, in the quarter ended April 4, 2020, related to the impairment intangible assets, property, plant and equipment and ROU assets of the ILS reporting unit of $33.9 million, $85.6 million and $1.8 million, respectively.

Our indebtedness following the Rofin merger is substantially greater than our indebtedness prior to the merger. This increased level of indebtedness could adversely affect us, including by decreasing our business flexibility, and will increase our borrowing costs.

In November 2016, we entered into a credit agreement (the "Credit Agreement"), which provided for a 670.0 million Euro term loan, all of which was drawn, and a $100.0 million revolving credit facility, under which a 10 million Euro letter of credit was issued. As of July 4, 2020, 359.9 million Euros were outstanding under the term loan. As of July 4, 2020, the revolving credit facility had been used for guarantees of 10.0 million Euros as well as borrowings of $10.0 million. We may incur additional indebtedness in the future by accessing the revolving credit facility and/or entering into new financing arrangements. Our ability to pay interest and repay the principal of our current indebtedness is dependent upon our ability to manage our business operations and the ongoing interest rate environment. There can be no assurance that we will be able to manage any of these risks successfully.

The Credit Agreement contains customary affirmative covenants, including covenants regarding the payment of taxes and other obligations, maintenance of insurance, reporting requirements and compliance with applicable laws and regulations, and negative covenants, including covenants limiting the ability of us and our subsidiaries to, among other things, incur debt, grant liens, make investments, make certain restricted payments, transact with affiliates, and sell assets. The Credit Agreement also requires us and our subsidiaries to maintain a senior secured net leverage ratio as of the last day of each fiscal quarter of less of than or equal to 3.50 to 1.00. The Credit Agreement contains customary events of default that include, among other things, payment defaults, cross defaults with certain other indebtedness, violation of covenants, inaccuracy of representations and warranties in any material respect, change in control of us and Coherent Holding BV & Co. K.G. (formerly Coherent Holding
59

Table of Contents
GmbH), judgment defaults, and bankruptcy and insolvency events. If an event of default exists, the lenders may require the immediate payment of all obligations and exercise certain other rights and remedies provided for under the Credit Agreement, the other loan documents and applicable law. The acceleration of such obligations is automatic upon the occurrence of a bankruptcy and insolvency event of default. There can be no assurance that we will have sufficient financial resources or we will be able to arrange financing to repay our borrowings at such time.

Our substantially increased indebtedness and higher debt-to-equity ratio as a result of the Rofin merger in comparison to that prior to the merger will have the effect, among other things, of reducing our flexibility to respond to changing business and economic conditions and will increase our borrowing costs. In addition, the amount of cash required to service our increased indebtedness levels and thus the demands on our cash resources will be greater than the amount of cash flows required to service our indebtedness or that of Rofin individually prior to the merger. The increased levels of indebtedness could also reduce funds available for our investments in product development as well as capital expenditures, dividends, share repurchases and other activities and may create competitive disadvantages for us relative to other companies with lower debt levels.

Some of our laser systems are complex in design and may contain defects that are not detected until deployed by our customers, which could increase our costs and reduce our net sales.

Lasers and laser systems are inherently complex in design and require ongoing regular maintenance. The manufacture of our lasers, laser products and systems involves a highly complex and precise process. As a result of the technological complexity of our products, in particular our excimer laser annealing tools used in the flat panel display market, changes in our or our suppliers' manufacturing processes or the inadvertent use of defective materials by us or our suppliers could result in a material adverse effect on our ability to achieve acceptable manufacturing yields and product reliability. To the extent that we do not achieve and maintain our projected yields or product reliability, our business, operating results, financial condition and customer relationships would be adversely affected. We provide warranties on a majority of our product sales, and reserves for estimated warranty costs are recorded during the period of sale. The determination of such reserves requires us to make estimates of failure rates and expected costs to repair or replace the products under warranty. We typically establish warranty reserves based on historical warranty costs for each product line. If actual return rates and/or repair and replacement costs differ significantly from our estimates, adjustments to cost of sales may be required in future periods which could have an adverse effect on our results of operations.

Our customers may discover defects in our products after the products have been fully deployed and operated, including under the end user's peak stress conditions. In addition, some of our products are combined with products from other vendors, which may contain defects. As a result, should problems occur, it may be difficult to identify the source of the problem. If we are unable to identify and fix defects or other problems, we could experience, among other things:

loss of customers or orders;

increased costs of product returns and warranty expenses;

damage to our brand reputation;

failure to attract new customers or achieve market acceptance;

diversion of development, engineering and manufacturing resources; and

legal actions by our customers and/or their end users.

The occurrence of any one or more of the foregoing factors could seriously harm our business, financial condition and results of operations.

Continued volatility in the advanced packaging and semiconductor manufacturing markets could adversely affect our business, financial condition and results of operations.

A portion of our net sales in the microelectronics market depends on the demand for our products by advanced packaging applications and semiconductor equipment companies. These markets have historically been characterized by sudden and severe cyclical variations in product supply and demand, which have often severely affected the demand for semiconductor manufacturing equipment, including laser-based tools and systems. The timing, severity and duration of these market cycles are difficult to predict, especially during the ongoing COVID-19 pandemic, and we may not be able to respond effectively to these
60

Table of Contents
cycles. The continuing uncertainty in these markets severely limits our ability to predict our business prospects or financial results in these markets.

During industry downturns, our net sales from these markets may decline suddenly and significantly. Our ability to rapidly and effectively reduce our cost structure in response to such downturns is limited by the fixed nature of many of our expenses in the near term and by our need to continue our investment in next-generation product technology and to support and service our products. In addition, due to the relatively long manufacturing lead times for some of the systems and subsystems we sell to these markets, we may incur expenditures or purchase raw materials or components for products we cannot sell. Accordingly, downturns in the semiconductor capital equipment market may materially harm our operating results. Conversely, when upturns in these markets occur, we must be able to rapidly and effectively increase our manufacturing capacity to meet increases in customer demand that may be extremely rapid, and if we fail to do so we may lose business to our competitors and our relationships with our customers may be harmed.

Worldwide economic conditions and related uncertainties could negatively impact demand for our products and results of operations.

Volatility and disruption in the capital and credit markets, depressed consumer confidence, government economic policies, negative economic conditions, volatile corporate profits and reduced capital spending could negatively impact demand for our products. In particular, it is difficult to develop and implement strategy, sustainable business models and efficient operations, as well as effectively manage supply chain relationships, in the face of such conditions, including uncertainty regarding the ability of some of our suppliers to continue operations and provide us with uninterrupted supply flow. Our ability to maintain our research and development investments in our broad product offerings may be adversely impacted in the event that our future sales decline or remain flat. Spending and the timing thereof by consumers and businesses have a significant impact on our results and, where such spending is delayed or cancelled, it could have a material negative impact on our operating results. Global economic conditions have become more uncertain and challenging as the effects of the COVID-19 pandemic continue to have a significant adverse effect on the global economy. Weakness in our end markets has negatively impacted our bookings, net sales, gross margin and operating expenses, and, if it continues, would have a material adverse effect on our business, financial condition and results of operations.

Uncertainty in global fiscal policy has likely had an adverse impact on global financial markets and overall economic activity in recent years. Should this uncertain financial policy continue to occur or recur, it would likely continue to, and may in the future, negatively impact global economic activity. Any weakness in global economies would also likely have negative repercussions on U.S. and global credit and financial markets, and further exacerbate sovereign debt concerns in the European Union. All of these factors would likely adversely impact the global demand for our products and the performance of our investments, and would likely have a material adverse effect on our business, results of operations and financial condition.

Financial turmoil affecting the banking system and financial markets, as has occurred in recent years, could result in tighter credit markets and lower levels of liquidity in some financial markets. There could be a number of follow-on effects from a tightened credit environment on our business, including the insolvency of key suppliers or their inability to obtain credit to finance development and/or manufacture products resulting in product delays; inability of customers to obtain credit to finance purchases of our products and/or customer insolvencies; and failure of financial institutions negatively impacting our treasury functions. In the event our customers are unable to obtain credit or otherwise pay for our shipped products it could significantly impact our ability to collect on our outstanding accounts receivable. Other income and expense also could vary materially from expectations depending on gains or losses realized on the sale or exchange of financial instruments; impairment charges resulting from revaluations of debt and equity securities and other investments; interest rates; cash balances; and changes in fair value of derivative instruments. Volatility in the financial markets and any overall economic uncertainty increase the risk that the actual amounts realized in the future on our financial instruments could differ significantly from the fair values currently assigned to them. Uncertainty about global economic conditions could also continue to increase the volatility of our stock price.

In addition, political and social turmoil related to international conflicts, terrorist acts, civil unrest and mass migration may put further pressure on economic conditions in the United States and the rest of the world. Unstable economic, political and social conditions make it difficult for our customers, our suppliers and us to accurately forecast and plan future business activities. If such conditions persist, our business, financial condition and results of operations could suffer. Additionally, unstable economic conditions can provide significant pressures and burdens on individuals, which could cause them to engage in inappropriate business conduct. See "Part I, Item 4. Controls and Procedures."

Our cash and cash equivalents and short-term investments are managed through various banks around the world and volatility in the capital and credit market conditions could cause financial institutions to fail or materially harm service levels provided by such banks, both of which could have an adverse impact on our ability to timely access funds.

World capital and credit markets have been and may continue to experience volatility and disruption. In some cases, the markets have exerted downward pressure on stock prices and credit capacity for certain issuers, as well as pressured the solvency of some financial institutions. These financial institutions, including banks, have had difficulty timely performing regular services and in some cases have failed or otherwise been largely taken over by governments. We maintain our cash, cash equivalents and short-term investments with a number of financial institutions around the world. Should some or all of these financial institutions fail or otherwise be unable to timely perform requested services, we would likely have limited ability to timely access our cash deposited with such institutions, or, in extreme circumstances the failure of such institutions could cause us to be unable to access cash for the foreseeable future. If we are unable to quickly access our funds when we need them, we may need to increase the use of our existing credit lines or access more expensive credit, if available. If we are unable to access our cash or if we access existing or additional credit or are unable to access additional credit, it could have a negative impact on our operations, including our reported net income. In addition, the willingness of financial institutions to continue to accept our cash deposits will impact our ability to diversify our investment risk among institutions.

We are exposed to credit risk and fluctuations in the market values of our investment portfolio.

Although we have not recognized any material losses on our cash, cash equivalents and short-term investments, future declines in their market values could have a material adverse effect on our financial condition and operating results. Given the global nature of our business, we have investments both domestically and internationally. There has recently been growing pressure on the creditworthiness of sovereign nations, particularly in Europe where a significant portion of our cash, cash equivalents and short-term investments are invested, which results in corresponding pressure on the valuation of the securities issued by such nations. Additionally, our overall investment portfolio is often concentrated in government-issued securities such as U.S. Treasury securities and government agencies, corporate notes, commercial paper and money market funds. Credit ratings and pricing of these investments can be negatively impacted by liquidity, credit deterioration or losses, financial results, or other factors. Additionally, liquidity issues or political actions by sovereign nations could result in decreased values for our investments in certain government securities. As a result, the value or liquidity of our cash, cash equivalents and short-term investments could decline or become materially impaired, which could have a material adverse effect on our financial condition and operating results. See "Part I, Item 3. Quantitative and Qualitative Disclosures about Market Risk."

Our future success depends on our ability to increase our sales volumes and decrease our costs to offset potential declines in the average selling prices ("ASPs") of our products and, if we are unable to realize greater sales volumes and lower costs, our operating results may suffer.

Our ability to increase our sales volume and our future success depends on the continued growth of the markets for lasers, laser systems and related accessories, as well as our ability to identify, in advance, emerging markets for laser-based systems and to manage our manufacturing capacity to meet customer demands. We cannot assure you that we will be able to successfully identify, on a timely basis, new high-growth markets in the future. Moreover, we cannot assure you that new markets will develop for our products or our customers' products, or that our technology or pricing will enable such markets to develop. Future demand for our products is uncertain and will depend to a great degree on continued technological development and the introduction of new or enhanced products. If this does not continue, sales of our products may decline and our business will be harmed.

We have in the past experienced decreases in the ASPs of some of our products. As competing products become more widely available or lower-cost products come to market, the ASPs of our products may decrease. If we are unable to offset any decrease in our ASPs by increasing our sales volumes, our net sales will decline. In addition, to maintain our gross margins, we must continue to reduce the cost of manufacturing our products while maintaining their high quality. From time to time, our products, like many complex technological products, may fail in greater frequency than anticipated. This can lead to further charges, which can result in higher costs, lower gross margins and lower operating results. Furthermore, as ASPs of our current products decline, we must develop and introduce new products and product enhancements with higher margins. If we cannot maintain our gross margins, our operating results could be seriously harmed, particularly if the ASPs of our products decrease significantly.

Our future success depends on our ability to develop and successfully introduce new and enhanced products that meet the needs of our customers.

Our current products address a broad range of commercial and scientific research applications in the photonics markets. We cannot assure you that the market for these applications will continue to generate significant or consistent demand for our products. Demand for our products could be significantly diminished by disrupting technologies or products that replace them or render them obsolete. Furthermore, the new and enhanced products in certain markets generally continue to be smaller in size and have lower ASPs, and therefore, we have to sell more units to maintain revenue levels. Accordingly, we must continue to invest in research and development in order to develop competitive products. Ongoing restrictions resulting from the COVID-19 pandemic have had a negative impact on the work on some of our research and development programs due to the inability of some personnel being able to work in applicable regional labs.

Our future success depends on our ability to anticipate our customers' needs and develop products that address those needs. Introduction of new products and product enhancements will require that we effectively transfer production processes from research and development to manufacturing and coordinate our efforts with those of our suppliers to achieve volume production rapidly. If we fail to transfer production processes effectively, develop product enhancements or introduce new products in sufficient quantities to meet the needs of our customers as scheduled, our net sales may be reduced and our business may be harmed.

We face risks associated with our international operations and sales that could harm our financial condition and results of operations.

For the three and nine months ended July 4, 2020, 78% and 76%, respectively, of our net sales were derived from customers outside of the United States. For fiscal 2019, 2018 and 2017, 76%, 84% and 83%, respectively, of our net sales were derived from customers outside of the United States. We anticipate that international sales, particularly in Asia, will continue to account for a significant portion of our net sales in the foreseeable future.

A global economic slowdown or a natural disaster could have a negative effect on various international markets in which we operate, such as the earthquake, tsunami and resulting nuclear disaster in Japan and the flooding in Thailand. Such a slowdown may cause us to reduce our presence in certain countries, which may negatively affect the overall level of business in such countries. Our international sales are primarily through our direct sales force. Additionally, some international sales are made through international distributors and representatives. Currently, the COVID-19 pandemic is having a significant adverse effect on the global economy, which is affecting the various markets in which we operate.

Our international operations and sales are subject to a number of risks, including:

compliance with applicable import/export regulations, tariffs and trade barriers, including recently instituted or proposed changes in trade policies by the U.S. and any corresponding retaliatory actions by affected countries, in particular with respect to China;

longer accounts receivable collection periods;

the impact of recessions and other economic conditions in economies outside the United States, including, for example, recent dips in the manufacturing Purchasing Managers’ Index ("PMI") as well as the Institute of Supply Management ("ISM") data in the Eurozone, in particular in Germany;

unexpected changes in regulatory requirements and compliance with applicable regulatory requirements;

product certification requirements;

environmental regulations;

reduced protection for intellectual property rights in some countries;

potentially adverse tax consequences;

political and economic instability, such as the current situation between the governments of Japan and South Korea, which has led to the imposition of trade restrictions by the Japanese government affecting the export to South Korea of certain products and materials used in the manufacture of flat panel displays and in the semiconductor industry;
63

Table of Contents

compliance with applicable United States and foreign anti-corruption laws;

less than favorable contract terms;

reduced ability to enforce contractual obligations;

cultural and management differences;

reliance in some jurisdictions on third party sales channel partners;

preference for locally produced products; and

shipping and other logistics complications.

Our business could also be impacted by international conflicts, terrorist and military activity including, in particular, any such conflicts on the Korean peninsula, civil unrest and pandemics, any of which could cause a slowdown in customer orders, cause customer order cancellations or negatively impact availability of supplies or limit our ability to timely service our installed base of products.

We are also subject to the risks of fluctuating foreign currency exchange rates, which could materially adversely affect the sales price of our products in foreign markets, as well as the costs and expenses of our international subsidiaries. While we use forward exchange contracts and other risk management techniques to hedge our foreign currency exposure, we remain exposed to the economic risks of foreign currency fluctuations.

If we are unable to protect our proprietary technology, our competitive advantage could be harmed.

Maintenance of intellectual property rights and the protection thereof is important to our business. We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. Our patent applications may not be approved, any patents that may be issued may not sufficiently protect our intellectual property and any issued patents may be challenged by third parties. Other parties may independently develop similar or competing technology or design around any patents that may be issued to us. We cannot be certain that the steps we have taken will prevent the misappropriation of our intellectual property, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. Further, we may be required to enforce our intellectual property or other proprietary rights through litigation, which, regardless of success, could result in substantial costs and diversion of management's attention. Additionally, there may be existing patents of which we are unaware that could be pertinent to our business and it is not possible for us to know whether there are patent applications pending that our products might infringe upon since these applications are often not publicly available until a patent is issued or published.

We have been and may in the future be subject to claims or litigation from third parties, for claims of infringement of their proprietary rights or to determine the scope and validity of our proprietary rights or the proprietary rights of competitors or other rights holders. These claims could result in costly litigation and the diversion of our technical and management personnel. Adverse resolution of litigation may harm our operating results or financial condition.

In recent years, there has been significant litigation in the United States and around the world involving patents and other intellectual property rights. This has been seen in our industry, for example in the concluded patent-related litigation between IMRA America, Inc. ("Imra") and IPG Photonics Corporation and in Imra's concluded patent-related litigation against two of our German subsidiaries. From time to time, like many other technology companies, we have received communications from other parties asserting the existence of patent rights, copyrights, trademark rights or other intellectual property rights which such third parties believe may cover certain of our products, processes, technologies or information. In the future, we may be a party to litigation to protect our intellectual property or as a result of an alleged infringement of others' intellectual property whether through direct claims or by way of indemnification claims of our customers, as, in some cases, we contractually agree to indemnify our customers against third-party infringement claims relating to our products. These claims and any resulting lawsuit, if successful, could subject us to significant liability for damages or invalidation of our proprietary rights. These lawsuits, regardless of their success, would likely be time-consuming and expensive to resolve and would divert management time and attention. In addition to paying possibly significant monetary damages, any potential intellectual property litigation could also force us to do one or more of the following:

 stop manufacturing, selling or using our products that use the infringed intellectual property;
64

Table of Contents

obtain from the owner of the infringed intellectual property right a license to sell or use the relevant technology, although such license may not be available on reasonable terms, or at all; or

redesign the products that use the technology.

If we are forced to take any of these actions or are otherwise a party to lawsuits of this nature, we may incur significant losses and our business may be seriously harmed. We do not have insurance to cover potential claims of this type.

If our goodwill or intangible assets become impaired, we may be required to record a significant charge to earnings.

Under accounting principles generally accepted in the United States, we review our intangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Goodwill is required to be tested for impairment at least annually. Factors that may be considered in determining whether a change in circumstances indicating that the carrying value of our goodwill or other intangible assets may not be recoverable include declines in our stock price and market capitalization or future cash flows projections. A decline in our stock price, or any other adverse change in market conditions, particularly if such change has the effect of changing one of the critical assumptions or estimates we used to calculate the estimated fair value of our reporting units, could result in a change to the estimation of fair value that could result in an impairment charge. Any such material charges, whether related to goodwill or purchased intangible assets, may have a material negative impact on our financial and operating results. For example, in the quarter ended April 4, 2020, the worldwide spread of COVID-19 created significant volatility, uncertainty and disruption to the global economy, representing an indicator to test our goodwill for impairment. As a result of that test, we recorded a non-cash pre-tax charge, in the quarter ended April 4, 2020, related to the ILS reporting unit of $327.2 million, reducing the goodwill balance of the reporting unit to zero. In addition, we performed impairment tests on the long-lived assets allocated to the asset group of the ILS reporting unit, including intangible assets, property, plant and equipment and ROU assets as of April 4, 2020 and recorded non-cash pre-tax charges, in the quarter ended April 4, 2020, related to the impairment intangible assets, property, plant and equipment and ROU assets of the ILS reporting unit of $33.9 million, $85.6 million and $1.8 million, respectively.

We depend on skilled personnel to operate our business effectively in a rapidly changing market, and if we are unable to retain existing or hire additional personnel when needed, or manage transitions among members of our leadership team, in particular the recently announced transition of our President and Chief Executive Officer, our ability to develop and sell our products could be harmed.

Our ability to continue to attract and retain highly skilled personnel will be a critical factor in determining whether we will be successful in the future. Recruiting and retaining highly skilled personnel in certain functions continues to be difficult. At certain locations where we operate, the cost of living is extremely high and it may be difficult to retain key employees and management at a reasonable cost. We may not be successful in attracting, assimilating or retaining qualified personnel to fulfill our current or future needs, which could adversely affect our growth and our business.

Our future success depends upon the continued services of our executive officers and other key engineering, sales, marketing, manufacturing and support personnel, as well as our ability to effectively transition to their successors. Most recently, we appointed a new President and Chief Executive Officer in April 2020, at which time our former President and CEO, who had served in such position since 2002, transitioned to the role of special advisor to the Company. This transition may be disruptive to our business, and if we are unable to execute an orderly transition and successfully integrate our new CEO into our management team, our revenue, operating results and financial condition may be adversely affected. In addition, our former head of sales transitioned to the role of special advisor to the CEO at the end of fiscal 2019. Any future changes to our executive and senior management teams, including hires or departures, could cause further disruption to our business and have a negative impact on our operating performance, while these operational areas are in transition. We can provide no assurance that we will be able to find suitable successors to key roles as transitions occur or that any identified successor will be successfully integrated into our management team. Our inability to do so, or to retain other key employees or effectively transition to their successors, or any delay in filling any such positions, could harm our business and our results of operations.

The long sales cycles for our products may cause us to incur significant expenses without offsetting net sales.

Customers often view the purchase of our products as a significant and strategic decision. As a result, customers typically expend significant effort in evaluating, testing and qualifying our products before making a decision to purchase them, resulting in a lengthy initial sales cycle. While our customers are evaluating our products and before they place an order with us, we may incur substantial sales and marketing and research and development expenses to customize our products to the customers' needs. We may also expend significant management efforts, increase manufacturing capacity and order long lead-time
65

Table of Contents
components or materials prior to receiving an order. Even after this evaluation process, a potential customer may not purchase our products. As a result, these long sales cycles may cause us to incur significant expenses without ever receiving net sales to offset such expenses.

The markets in which we sell our products are intensely competitive and increased competition could cause reduced sales levels, reduced gross margins or the loss of market share.

Competition in the various photonics markets in which we provide products is very intense. We compete against a number of large public and private companies, including IPG Photonics Corporation, Lumentum Holdings Inc., MKS Instruments, Inc., Novanta Inc., nlight, Inc., II-VI Incorporated, Wuhan Raycus Fiber Laser Technologies Co., Ltd, and Trumpf GmbH, as well as other smaller companies. Some of our competitors are large companies that have significant financial, technical, marketing and other resources. These competitors may be able to devote greater resources than we can to the development, promotion, sale and support of their products. Some of our competitors are much better positioned than we are to acquire other companies in order to gain new technologies or products that may displace our product lines. Any of these acquisitions could give our competitors a strategic advantage. Any business combinations or mergers among our competitors, forming larger companies with greater resources, could result in increased competition, price reductions, reduced margins or loss of market share, any of which could materially and adversely affect our business, results of operations and financial condition.

Additional competitors may enter the markets in which we serve, both foreign and domestic, and we are likely to compete with new companies in the future. For example, in recent years there have been a growing number of companies in China that, in some cases aided by government subsidies, are targeting our markets and are exerting significant price pressure in certain of our product markets, in particular the HPFL products used in the metal cutting market in China. These companies will likely in the future be able to expand into broader product markets, which may result in additional competitive pressures on us. We may also encounter potential customers that, due to existing relationships with our competitors, are committed to the products offered by these competitors. Further, our current or potential customers may determine to develop and produce products for their own use which are competitive to our products. Such vertical integration could reduce the market opportunity for our products. As a result of the foregoing factors, we expect that competitive pressures may result in price reductions, reduced margins, loss of sales and loss of market share. In addition, in markets where there are a limited number of customers, competition is particularly intense.

If we fail to accurately forecast component and material requirements for our products, we could incur additional costs and incur significant delays in shipments, which could result in a loss of customers.

We use rolling forecasts based on anticipated product orders and material requirements planning systems to determine our product requirements. It is very important that we accurately predict both the demand for our products and the lead times required to obtain the necessary components and materials. We depend on our suppliers for most of our product components and materials. Lead times for components and materials that we order vary significantly and depend on factors including the specific supplier requirements, the size of the order, contract terms and current market demand for components. For substantial increases in our sales levels of certain products, some of our suppliers may need at least nine months lead-time. If we overestimate our component and material requirements, we may have excess inventory, which would increase our costs. If we underestimate our component and material requirements, we may have inadequate inventory, which could interrupt and delay delivery of our products to our customers. We expect that the volatility and uncertainty created by the COVID-19 pandemic in the markets we serve will exacerbate these issues, and any of these occurrences would negatively impact our net sales, business or operating results.

Our reliance on contract manufacturing and outsourcing may adversely impact our financial results and operations due to our decreased control over the performance and timing of certain aspects of our manufacturing.

Our manufacturing strategy includes partnering with contract manufacturers to outsource non-core subassemblies and less complex turnkey products, including some performed at international sites located in Asia and Eastern Europe. Our ability to resume internal manufacturing operations for certain products and components in a timely manner may be eliminated. The cost, quality, performance and availability of contract manufacturing operations are and will be essential to the successful production and sale of many of our products. Our financial condition or results of operation could be adversely impacted if any contract manufacturer or other supplier is unable for any reason, including as a result of the COVID-19 pandemic and the negative effect it is having on the global economy, to meet our cost, quality, performance, and availability standards. We may not be able to provide contract manufacturers with product volumes that are high enough to achieve sufficient cost savings. If shipments fall below forecasted levels, we may incur increased costs or be required to take ownership of the inventory. Also, our ability to control the quality of products produced by contract manufacturers may be limited and quality issues may not be resolved in a timely manner, which could adversely impact our financial condition or results of operations.

If we fail to effectively manage our growth or, alternatively, our spending during downturns, our business could be disrupted, which could harm our operating results.

Growth in sales, combined with the challenges of managing geographically dispersed operations, can place a significant strain on our management systems and resources, and our anticipated growth in future operations could continue to place such a strain. The failure to effectively manage our growth could disrupt our business and harm our operating results. Our ability to successfully offer our products and implement our business plan in evolving markets requires an effective planning and management process. In economic downturns, we must effectively manage our spending and operations to ensure our competitive position during the downturn, as well as our future opportunities when the economy improves, remain intact. The failure to effectively manage our spending and operations could disrupt our business and harm our operating results.

Historically, acquisitions have been an important element of our strategy. However, we may not find suitable acquisition candidates in the future and we may not be able to successfully integrate and manage acquired businesses. Any acquisitions we make could disrupt our business and harm our financial condition.

We have in the past made strategic acquisitions of other corporations and entities, including Ondax in October 2018, OR Laser in March 2018 and Rofin in November 2016, as well as asset purchases, and we continue to evaluate potential strategic acquisitions of complementary companies, products and technologies. In the event of any future acquisitions, we could:

issue stock that would dilute our current stockholders' percentage ownership;

pay cash that would decrease our working capital;

incur debt;

assume liabilities; or

incur expenses related to impairment of goodwill and other long-lived assets, as we incurred in the quarter ending April 4, 2020 totaling $451.0 million.

Acquisitions also involve numerous risks, including:

problems combining the acquired operations, systems, technologies or products;

an inability to realize expected operating efficiencies or product integration benefits;

difficulties in coordinating and integrating geographically separated personnel, organizations, systems and facilities;

difficulties integrating business cultures;

unanticipated costs or liabilities, including the costs associated with improving the internal controls of the acquired company;

diversion of management's attention from our core businesses;

adverse effects on existing business relationships with suppliers and customers;

potential loss of key employees, particularly those of the purchased organizations;

incurring unforeseen obligations or liabilities in connection with acquisitions; and

the failure to complete acquisitions even after signing definitive agreements which, among other things, would result in the expensing of potentially significant professional fees and other charges in the period in which the acquisition or negotiations are terminated.

We cannot assure you that we will be able to successfully identify appropriate acquisition candidates, to integrate any businesses, products, technologies or personnel that we might acquire in the future or achieve the anticipated benefits of such transactions, which may harm our business.

Our market is unpredictable and characterized by rapid technological changes and evolving standards demanding a significant investment in research and development, and, if we fail to address changing market conditions, our business and operating results will be harmed.

The photonics industry is characterized by extensive research and development, rapid technological change, frequent new product introductions, changes in customer requirements and evolving industry standards. Because this industry is subject to rapid change, it is difficult to predict its potential size or future growth rate. Our success in generating net sales in this industry will depend on, among other things:

maintaining and enhancing our relationships with our customers;

the education of potential end-user customers about the benefits of lasers and laser systems; and

our ability to accurately predict and develop our products to meet industry standards.

We cannot assure you that our expenditures for research and development will result in the introduction of new products or, if such products are introduced, that those products will achieve sufficient market acceptance or generate sales to offset the costs of development. Our failure to address rapid technological changes in our markets could adversely affect our business and results of operations.

We are exposed to lawsuits in the normal course of business which could have a material adverse effect on our business, operating results, or financial condition.

We are exposed to lawsuits in the normal course of our business, including product liability claims, if personal injury, death or commercial losses occur from the use of our products. As a public company our stock price fluctuates for a variety of different reasons, some of which may be related to broader industry and/or market factors. As a result, from time-to-time we may be subject to the risk of litigation due to the fluctuation in stock price or other governance or market-related factors. While we typically maintain business insurance, including directors' and officers' policies, litigation can be expensive, lengthy, and disruptive to normal business operations, including the potential impact of indemnification obligations for individuals named in any such lawsuits. We may not, however, be able to secure insurance coverage on terms acceptable to us in the future. Moreover, the results of complex legal proceedings are difficult to predict. An unfavorable resolution of a particular lawsuit, including a recall or redesign of products if ultimately determined to be defective, could have a material adverse effect on our business, operating results, or financial condition.

We use standard laboratory and manufacturing materials that could be considered hazardous and we could be liable for any damage or liability resulting from accidental environmental contamination or injury.

Although most of our products do not incorporate hazardous or toxic materials and chemicals, some of the gases used in our excimer lasers and some of the liquid dyes used in some of our scientific laser products are highly toxic. In addition, our operations involve the use of standard laboratory and manufacturing materials that could be considered hazardous. Also, if a facility fire were to occur at our Sunnyvale, California site and were to spread to a reactor used to grow semiconductor wafers, it could release highly toxic emissions. We believe that our safety procedures for handling and disposing of such materials comply with all federal, state and offshore regulations and standards. However, the risk of accidental environmental contamination or injury from such materials cannot be entirely eliminated. In the event of such an accident involving such materials, we could be liable for damages and such liability could exceed the amount of our liability insurance coverage and the resources of our business which could have an adverse effect on our financial results or our business as a whole.

Compliance or the failure to comply with current and future environmental regulations could cause us significant expense.

We are subject to a variety of federal, state, local and foreign environmental regulations relating to the use, storage, discharge and disposal of hazardous chemicals used during our manufacturing process or requiring design changes or recycling of products we manufacture. If we fail to comply with any present and future regulations, we could be subject to future liabilities, the suspension of production or a prohibition on the sale of products we manufacture. In addition, such regulations could restrict our ability to expand our facilities or could require us to acquire costly equipment, or to incur other significant expenses to comply with environmental regulations, including expenses associated with the recall of any non-compliant product and the management of historical waste.

68

Table of Contents
From time to time new regulations are enacted, and it is difficult to anticipate how such regulations will be implemented and enforced. We continue to evaluate the necessary steps for compliance with regulations as they are enacted. These regulations include, for example, the Registration, Evaluation, Authorization and Restriction of Chemical substances ("REACH"), the Restriction on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive ("RoHS") and the Waste Electrical and Electronic Equipment Directive ("WEEE") enacted in the European Union, which regulate the use of certain hazardous substances in, and require the collection, reuse and recycling of waste from, certain products we manufacture. This and similar legislation that has been or is in the process of being enacted in Japan, China, South Korea and various states of the United States may require us to re-design our products to ensure compliance with the applicable standards, for example by requiring the use of different types of materials. These redesigns or alternative materials may detrimentally impact the performance of our products, add greater testing lead-times for product introductions or have other similar effects. We believe we comply with all such legislation where our products are sold, and we will continue to monitor these laws and the regulations being adopted under them to determine our responsibilities. In addition, we are monitoring legislation relating to the reduction of carbon emissions from industrial operations to determine whether we may be required to incur any additional material costs or expenses associated with our operations. We are not currently aware of any such material costs or expenses. The SEC has promulgated rules requiring disclosure regarding the use of certain "conflict minerals" mined from the Democratic Republic of Congo and adjoining countries and procedures regarding a manufacturer's efforts to prevent the sourcing of such minerals. The implementation of such rules has required us to incur additional expense and internal resources and may continue to do so in the future, particularly in the event that only a limited pool of suppliers are available to certify that products are free from "conflict minerals." Our failure to comply with any of the foregoing regulatory requirements or contractual obligations could result in our being directly or indirectly liable for costs, fines or penalties and third-party claims, and could jeopardize our ability to conduct business in the United States and foreign countries.

Our and our customers' operations would be seriously harmed if our logistics or facilities or those of our suppliers, our customers' suppliers or our contract manufacturers were to experience catastrophic loss.

Our operations, logistics and facilities and those of our customers, suppliers and contract manufacturers could be subject to a catastrophic loss from fire, flood, earthquake, volcanic eruption, work stoppages, power outages, acts of war, pandemics such as COVID-19, energy shortages, theft of assets, other natural disasters or terrorist activity. A substantial portion of our research and development activities, manufacturing, our corporate headquarters and other critical business operations are located near major earthquake faults in Santa Clara, California, an area with a history of seismic events. Any such loss or detrimental impact to any of our operations, logistics or facilities could disrupt our operations, delay production, shipments and net sales and result in large expenses to repair or replace the facility. While we have obtained insurance to cover most potential losses, after reviewing the costs and limitations associated with earthquake insurance, we have decided not to procure such insurance. We believe that this decision is consistent with decisions reached by numerous other companies located nearby. We cannot assure you that our existing insurance coverage will be adequate against all other possible losses.

Difficulties with our enterprise resource planning ("ERP") system and other parts of our global information technology system could harm our business and results of operation. If our network security measures are breached and unauthorized access is obtained to a customer's data or our data or our information technology systems, we may incur significant legal and financial exposure and liabilities.

Like many modern multinational corporations, we maintain a global information technology system, including software products licensed from third parties. Any system, network or Internet failures, misuse by system users, the hacking into or disruption caused by the unauthorized access by third parties or loss of license rights could disrupt our ability to timely and accurately manufacture and ship products or to report our financial information in compliance with the timelines mandated by the SEC. Any such failure, misuse, hacking, disruptions or loss would likely cause a diversion of management's attention from the underlying business and could harm our operations. In addition, a significant failure of our global information technology system could adversely affect our ability to complete an evaluation of our internal controls and attestation activities pursuant to Section 404 of the Sarbanes-Oxley Act of 2002.

Our information systems are subject to attacks, interruptions and failures.

As part of our day-to-day business, we store our data and certain data about our customers in our global information technology system. While our system is designed with access security, if a third party gains unauthorized access to our data, including any regarding our customers, such a security breach could expose us to a risk of loss of this information, loss of business, litigation and possible liability. Our security measures may be breached as a result of third-party action, including intentional misconduct by computer hackers, employee error, malfeasance or otherwise. Additionally, third parties may attempt to fraudulently induce employees or customers into disclosing sensitive information such as user names, passwords or other information in order to gain access to our customers' data or our data, including our intellectual property and other confidential business information, or

our information technology systems. Because the techniques used to obtain unauthorized access, or to sabotage systems, change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. Any unauthorized access could result in a loss of confidence by our customers, damage our reputation, disrupt our business, lead to legal liability and negatively impact our future sales. Additionally, such actions could result in significant costs associated with loss of our intellectual property, impairment of our ability to conduct our operations, rebuilding our network and systems, prosecuting and defending litigation, responding to regulatory inquiries or actions, paying damages or taking other remedial steps.

Changes in tax rates, tax liabilities or tax accounting rules could affect future results.

As a global company, we are subject to taxation in the United States and various other countries and jurisdictions. Significant judgment is required to determine our worldwide tax liabilities. A number of factors may affect our future effective tax rates including, but not limited to:

interpretation and impact of the recently enacted and aforementioned U.S. tax laws, the Tax Act and the CARES Act;

changes in our current and future global structure based on the Rofin acquisition and restructuring that involved significant movement of U.S. and foreign entities and our ability to maintain favorable tax treatment as a result of various Rofin restructuring efforts and business activities;

the outcome of discussions with various tax authorities regarding intercompany transfer pricing arrangements;

changes that involve other acquisitions, restructuring or an increased investment in technology outside of the United States to better align asset ownership and business functions with revenues and profits;

changes in the composition of earnings in countries or states with differing tax rates;

the resolution of issues arising from tax audits with various tax authorities, and in particular, the outcome of the German tax audits for fiscal 2010-2016 and the appeals of the South Korean fiscal 2014-2017 tax audits through the competent authority process between South Korea, Germany and the United States;

adjustments to estimated taxes upon finalization of various tax returns;

increases in expenses not deductible for tax purposes, including impairments of goodwill in connection with acquisitions;

our ability to meet the eligibility requirements for tax holidays of limited time tax-advantage status;

changes in available tax credits;

changes in share-based compensation;

changes in other tax laws or the interpretation of such tax laws, including the Base Erosion Profit Shifting action plan implemented by the Organization for Economic Co-operation and Development;

changes in generally accepted accounting principles; and

significant fluctuations in business activities due to the COVID-19 pandemic.

As indicated above, we are engaged in discussions with various tax authorities regarding the appropriate level of profitability for Coherent entities and this may result in changes to our worldwide tax liabilities. In addition, we are subject to regular examination of our income tax returns by the Internal Revenue Service ("IRS") and other tax authorities. We regularly assess the likelihood of favorable or unfavorable outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. Although we believe our tax estimates are reasonable, there can be no assurance that any final determination will not be materially different from the treatment reflected in our historical income tax provisions and accruals, which could materially and adversely affect our operating results and financial condition.

From time to time the United States, foreign and state governments make substantive changes to tax rules and the application of rules to companies. For example, the Tax Act has a significant impact on the taxation of Coherent including the U.S. tax
70

Table of Contents
treatment of our foreign operations. The Tax Act is subject to further interpretation by the U.S. federal and state governments and regulatory organizations, legislative updates or new regulations, or changes in accounting standards for income taxes. These actions may have a material impact on our financial results.

Changing laws, regulations and standards relating to corporate governance and public disclosure may create uncertainty regarding compliance matters.

Federal securities laws, rules and regulations, as well as the rules and regulations of self-regulatory organizations such as NASDAQ and the NYSE, require companies to maintain extensive corporate governance measures, impose comprehensive reporting and disclosure requirements, set strict independence and financial expertise standards for audit and other committee members and impose civil and criminal penalties for companies and their chief executive officers, chief financial officers and directors for securities law violations. These laws, rules and regulations have increased and will continue to increase the scope, complexity and cost of our corporate governance, reporting and disclosure practices, which could harm our results of operations and divert management's attention from business operations. Changing laws, regulations and standards relating to corporate governance and public disclosure may create uncertainty regarding compliance matters. New or changed laws, regulations and standards are subject to varying interpretations in many cases. As a result, their application in practice may evolve over time. We are committed to maintaining high standards of ethics, corporate governance and public disclosure. Complying with evolving interpretations of new or changed legal requirements may cause us to incur higher costs as we revise current practices, policies and procedures, and may divert management time and attention from revenue generating to compliance activities. If our efforts to comply with new or changed laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to practice, our reputation may also be harmed.

Governmental regulations, including tariffs and duties, affecting the import or export of products could negatively affect our business, financial condition and results of operations.

The United States, Germany, the European Union, the United Kingdom, China, South Korea, Japan and many other foreign governments impose tariffs and duties on the import and export of products, including some of those which we sell. In particular, given our worldwide operations, we pay duties on certain products when they are imported into the United States for repair work as well as on certain of our products which are manufactured by our foreign subsidiaries. These products can be subject to a duty on the product value. Additionally, the United States and various foreign governments have imposed tariffs, controls, export license requirements and restrictions on the import or export of some technologies, especially encryption technology. From time to time, government agencies have proposed additional regulation of encryption technology, such as requiring the escrow and governmental recovery of private encryption keys. Governmental regulation of encryption technology and regulation of imports or exports, or our failure to obtain required import or export licenses or other approvals for our products, could harm our international and domestic sales and adversely affect our net sales.

The U.S. has recently instituted or proposed changes in trade policies that include the negotiation or termination of trade agreements, the imposition of higher tariffs on imports into the United States including, in particular, on Chinese goods, economic sanctions on individuals, corporations or countries, and other government regulations affecting trade between the United States and other countries where we conduct our business. In addition, the Japanese government has recently instituted trade restrictions affecting the export to South Korea of certain products and materials used in the manufacture of flat panel displays and in the semiconductor industry. These policy changes and proposals could require time-consuming and expensive alterations to our business operations and may result in greater restrictions and economic disincentives on international trade, which could negatively impact our competitiveness in jurisdictions around the world as well as lead to an increase in costs in our supply chain. Given that we are a multinational corporation, with manufacturing located both in the United States and internationally, we may face additional susceptibility to negative impacts from these tariffs or change in trade policies regarding our inter-company trade practices. For example, we have recently seen a reduction in demand from our Chinese customers particularly in the materials processing space. Some of these customers are reevaluating expansion plans and delaying and, in limited cases, cancelling orders. In addition, new tariffs and other changes in U.S. trade policy could trigger retaliatory actions by affected countries, and certain foreign governments, including the Chinese government (which has imposed retaliatory tariffs on a range of U.S. goods including certain photonics products), some of which have instituted or are considering imposing trade sanctions on certain U.S. manufactured goods. Such changes by the United States and other countries have the potential to adversely impact U.S. and worldwide economic conditions, our industry and the global demand for our products, and as a result, could negatively affect our business, financial condition and results of operations.

As a multinational corporation, we may be subject to audits by tax, export and customs authorities, as well as other government agencies. For example, we were audited in South Korea for customs duties and value added tax for the period from March 2009 to March 2014. We were liable for additional payments, duties, taxes and penalties of $1.6 million, which we paid in the second
71

Table of Contents
quarter of fiscal 2016. Any future audits could lead to assessments that could have a material adverse effect on our business or financial position, results of operations, or cash flows.

In addition, compliance with the directives of the Directorate of Defense Trade Controls and other international jurisdictions' export control restrictions may result in substantial expenses and diversion of management's attention. Any failure to adequately address these directives could result in civil fines or suspension or loss of our export privileges, any of which could have a material adverse effect on our business or financial position, results of operations, or cash flows.

Failure to maintain effective internal controls may cause a loss of investor confidence in the reliability of our financial statements or cause us to delay filing our periodic reports with the SEC and adversely affect our stock price.

The SEC, as directed by Section 404 of the Sarbanes-Oxley Act of 2002, adopted rules requiring public companies to include a report of management on internal control over financial reporting in their annual reports on Form 10-K that contain an assessment by management of the effectiveness of our internal control over financial reporting. In addition, our independent registered public accounting firm must attest to and report on the effectiveness of our internal control over financial reporting. Although we test our internal control over financial reporting in order to ensure compliance with the Section 404 requirements, our failure to maintain adequate internal controls over financial reporting could result in an adverse reaction in the financial marketplace due to a loss of investor confidence in the reliability of our financial statements or a delay in our ability to timely file our periodic reports with the SEC, which ultimately could negatively impact our stock price.

Provisions of our charter documents and Delaware law, and our Change of Control and Leadership Change Severance Plan, may have anti-takeover effects that could prevent or delay a change in control.

Provisions of our certificate of incorporation and bylaws, as well as the terms of our Change of Control and Leadership Change Severance Plan, may discourage, delay or prevent a merger or acquisition, make a merger or acquisition more costly for a potential acquirer, or make removal of incumbent directors or officers more difficult. These provisions may discourage takeover attempts and bids for our common stock at a premium over the market price. These provisions include:

the ability of our Board of Directors to alter our bylaws without stockholder approval;

limiting the ability of stockholders to call special meetings; and

establishing advance notice requirements for nominations for election to our Board of Directors or for proposing matters that can be acted on by stockholders at stockholder meetings.

We are subject to Section 203 of the Delaware General Corporation Law, which prohibits a publicly-held Delaware corporation from engaging in a merger, asset or stock sale or other transaction with an interested stockholder for a period of three years following the date such person became an interested stockholder, unless prior approval of our board of directors is obtained or as otherwise provided. These provisions of Delaware law also may discourage, delay or prevent someone from acquiring or merging with us without obtaining the prior approval of our board of directors, which may cause the market price of our common stock to decline. In addition, we have adopted a change of control severance plan, which provides for the payment of a cash severance benefit to each eligible employee based on the employee's position. If a change of control occurs, our successor or acquirer will be required to assume and agree to perform all of our obligations under the change of control severance plan which may discourage potential acquirers or result in a lower stock price.

Exhibit 10.2

COHERENT
EQUITY INCENTIVE PLAN
GLOBAL RESTRICTED STOCK UNIT AGREEMENT
1. Grant.  The Company hereby grants to the Service Provider named in the Notice of Grant of Award and Award Agreement (the “Notice of Grant”) an award of Restricted Stock Units (“RSUs”), as set forth in the Notice of Grant, subject to the terms and conditions in this agreement, including any additional terms and conditions for the Service Provider’s country contained in the appendix attached hereto (the “Appendix” and, together with the Global Restricted Stock Unit Agreement, the “Agreement”) and in the Company’s Equity Incentive Plan (the “Plan”). Capitalized terms used and not defined in this Agreement shall have the meaning set forth in the Plan.
2. Company’s Obligation.  Each RSU granted represents the right to receive one Share on the vesting date.  Unless and until the RSUs vest, the Service Provider will have no right to receive Shares under such RSUs.  Prior to actual distribution of Shares pursuant to any vested RSUs, such RSUs will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.
3. Vesting Schedule.  The RSUs shall vest as set forth in the Notice of Grant, subject to paragraph 4.
4. Forfeiture upon Termination as a Service Provider.   Notwithstanding any contrary provision of this Agreement or the Notice of Grant, if the Service Provider terminates service as a Service Provider for any or no reason prior to vesting, the unvested RSUs awarded by this Agreement will thereupon be forfeited at no cost to the Company, subject to accelerated vesting as set forth in the Company’s Change of Control and Leadership Change Severance Plan (but only for participants in such plan), as amended from time to time. For purposes of the RSUs, the Service Provider’s service will be considered terminated as of the date that the Service Provider is no longer providing services to the Company or one of its Subsidiaries (regardless of the reason for such termination and whether or not later to be found invalid or in breach of employment laws in the jurisdiction where the Service Provider is employed or otherwise providing services or the terms of the Service Provider’s employment or other service agreement, if any), and unless otherwise expressly provided in this Agreement or by the Company’s Change of Control and Leadership Change Severance Plan (but only for participants in such plan) or determined by the Company, the Service Provider’s right to vest in the RSUs under the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g., the Service Provider’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Service Provider is employed or otherwise providing services or the terms of the Service Provider’s employment or other service agreement, if any); the Company shall have the exclusive discretion to determine when the Service Provider is no longer providing services for purposes of the RSUs (including whether the Service Provider may still be considered to be providing services while on a leave of absence).
5. Settlement upon Vesting.  Any RSUs that vest in accordance with paragraph 3 will be distributed to the Service Provider (or in the event of the Service Provider’s death, to his or her estate) in Shares.
6. Responsibility for Taxes.  The Service Provider acknowledges and agrees that, regardless of any action taken by the Company or, if different, the Service Provider’s employer or other service recipient (the “Employer”), the ultimate liability for all Tax-Related Items is and remains the Service Provider’s responsibility and may exceed the amount (if any) withheld by the Company or the Employer. The Service Provider further acknowledges that the Company and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the RSUs, including, but not limited to, the grant, vesting or settlement of the RSUs, the receipt of any dividends on Shares, and the subsequent sale of the Shares; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the RSUs to reduce or eliminate the Service Provider’s liability for Tax-Related Items or achieve any particular tax result.  Further, if the Service Provider has become subject to tax in more than one jurisdiction, the Service Provider acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.
1




Exhibit 10.2

Prior to any relevant taxable or tax withholding event, as applicable, the Service Provider will pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, the Company shall withhold in Shares otherwise deliverable to the Service Provider having a Fair Market Value equal to an amount that satisfies the Tax-Related Items required to be withheld. In the event that such withholding in Shares is problematic under applicable tax, securities or other laws, or has materially adverse accounting consequences, the Service Provider authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy their withholding obligations, if any, with regard to all Tax-Related Items by one or a combination of the following:
a. withholding from the Service Provider’s wages or other cash compensation payable to the Service Provider by the Company and/or the Employer; or
b. withholding from proceeds of the sale of Shares acquired upon vesting/settlement of the RSUs either through a voluntary sale or through a mandatory sale arranged by the Company (on the Service Provider’s behalf pursuant to this authorization without further consent).
The Company may withhold or account for Tax-Related Items by considering statutory withholding rates or other withholding rates, including maximum rates applicable in the Service Provider’s jurisdiction, in which case the Service Provider may receive a refund of any over-withheld amount in cash and will have no entitlement to the equivalent amount in Shares. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Service Provider is deemed to have been issued the full number of Shares subject to the vested RSUs, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items.
Finally, the Service Provider shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of the Service Provider’s participation in the Plan that cannot be satisfied by the means previously described.  The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares if the Service Provider fails to comply with the Service Provider’s obligations in connection with the Tax-Related Items.
7. Rights as Stockholder.  Neither the Service Provider nor any person claiming under or through the Service Provider will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to the Service Provider or the Service Provider’s broker.
8. Acknowledgements.  In accepting the grant of RSUs, the Service Provider acknowledges, understands and agrees that:
a. the Company (and not the Employer) is granting the RSUs, and will administer the Plan from outside the Service Provider’s country of residence if the Service Provider’s country of residence is outside the United States;
b. the benefits and rights provided under the Plan, if any, are wholly discretionary and do not constitute regular or periodic payments;
c. the Service Provider is voluntarily participating in the Plan;
d. the RSUs and the Shares subject to the RSUs, and the income from and value of same, are not intended to replace any pension rights or compensation;
e. the RSUs and the Shares subject to the RSUs, and the income from and value of same, are not part of normal or expected compensation for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, leave-related payments, bonuses, long-service awards, holiday pay, pension or retirement or welfare benefits or similar payments;
2




Exhibit 10.2

f. unless otherwise agreed with the Company, the RSUs and the Shares subject to the RSUs, and the income from and value of same, are not granted as consideration for, or in connection with, services the Service Provider may provide as a director of a Subsidiary;
g. no claim or entitlement to compensation or damages shall arise from forfeiture of the RSUs resulting from the termination of the Service Provider (for any reason whatsoever; and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Service Provider is employed or otherwise providing services or the terms of the Service Provider’s employment or other service agreement, if any);
h. the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty;
i. the grant of the RSUs, and all decisions with respect to any future grant of RSUs under the Plan, is at the complete discretion of the Company;
j. the grant of the RSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of Restricted Stock Units, or benefits in lieu of Restricted Stock Units, even if Restricted Stock Units have been granted in the past;
k. the Plan is established voluntarily by the Company, it is discretionary in nature, and it may be modified, amended, suspended, or terminated by the Company at any time, to the extent permitted by the Plan;
l. the grant of RSUs and the Service Provider’s participation in the Plan shall not create a right to employment or other service or be interpreted as forming an employment or other service contract with the Company and shall not interfere with the ability of the Employer to terminate the Service Provider’s employment or other service relationship (if any) at any time;
m. unless otherwise provided in the Plan or by the Company in its discretion, the RSUs and the benefits evidenced by this Agreement do not create any entitlement to have the RSUs or any such benefits transferred to, or assumed by, another company nor be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and
n. neither the Company, the Employer nor any other Subsidiary shall be liable for any foreign exchange rate fluctuation between the Service Provider’s local currency and the United States Dollar that may affect the value of the RSUs or of any amounts due to the Service Provider pursuant to the settlement of the RSUs or the subsequent sale of any Shares acquired upon settlement.
9. Data Privacy Information and Consent
a. Data Collection and Usage. The Company and the Employer collect, process and use certain personal information about the Service Provider, including, but not limited to, the Service Provider’s name, home address, telephone number, email address, date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any Shares or directorships held in the Company, details of all awards granted under the Plan or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in the Service Provider’s favor (“Data”), for the legitimate purpose of implementing, administering and managing the Service Provider’s participation in the Plan. The legal basis, where required, for the processing of Data is the Service Provider’s consent.
b. Stock Plan Administration Service Providers. The Company transfers Data to E*TRADE Financial Corporate Services, Inc. and certain of its affiliated companies (“E*TRADE”), an independent service provider based in the United States which is assisting the Company with the implementation, administration and management of the Plan. The Company may select a different service provider or additional service providers and share Data with such other provider serving in a similar manner. The Service Provider may
3




Exhibit 10.2

be asked to agree on separate terms and data processing practices with the service provider, with such agreement being a condition to the ability to participate in the Plan.
c. International Data Transfers. The Company and E*TRADE are based in the United States. The Service Provider’s country or jurisdiction may have different data privacy laws and protections than the United States. For example, the European Commission has issued a limited adequacy finding with respect to the United States that applies only to the extent companies register for the EU-U.S. Privacy Shield program. The Company has certified under the EU-U.S. Privacy Shield Program and relies on it for its transfer of Data from European Union countries to the U.S. Elsewhere, its legal basis for the transfer of Data, where required, is the Service Provider’s consent.
d. Data Retention. The Company will hold and use Data only as long as is necessary to implement, administer and manage the Service Provider’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax, exchange control, labor and securities laws. This may mean Data is retained even after the Service Provider's employment or other services with the Employer has terminated.
e. Voluntariness and Consequences of Consent Denial or Withdrawal. Participation in the Plan is voluntary and the Service Provider is providing the consents herein on a purely voluntary basis. If the Service Provider does not consent, or if the Service Provider later seeks to revoke the consent, his or her salary from or employment with the Employer will not be affected; the only consequence of refusing or withdrawing the consent is that the Company would not be able to grant RSUs to the Service Provider under the Plan or other equity awards or administer or maintain such awards.
f. Data Subject Rights. The Service Provider may have a number of rights under data privacy laws in his or her jurisdiction. Depending on where the Service Provider is based, such rights may include the right to (i) request access to or copies of Data the Company processes, (ii) rectify incorrect Data, (iii) delete Data, (iv) restrict the processing of Data, (v) restrict the portability of Data, (vi) lodge complaints with competent authorities in the Service Provider’s jurisdiction, and/or (vii) receive a list with the names and addresses of any potential recipients of Data. To receive clarification regarding these rights or to exercise these rights, the Service Provider can contact his or her local human resources representative.
g. Additional Consents. Upon request of the Company or the Employer, the Service Provider agrees to provide an executed data privacy consent form to the Company and/or the Employer (or any other agreements or consents that may be required by the Company and/or the Employer) that the Company and/or the Employer may deem necessary to obtain from the Service Provider for the purpose of administering his or her participation in the Plan in compliance with the applicable data privacy laws, either now or in the future. The Service Provider understands and agrees that he or she will not be able to participate in the Plan if he or she fails to provide any such consent or agreement requested by the Company and/or the Employer.
10. No Advice Regarding Grant.  The Company is not providing any tax, legal, or financial advice, nor is the Company making any recommendations regarding the Service Provider’s participation in the Plan or the Service Provider’s acquisition or sale of Shares.  The Service Provider should therefore consult with his or her own personal tax, legal, and financial advisors regarding the Service Provider’s participation in the Plan before taking any action related to the Plan.
11. Language.  The Service Provider acknowledges that he or she is proficient in the English language, or has consulted with an advisor who is sufficiently proficient in the English language, so as to allow the Service Provider to understand the terms and conditions of this Agreement. If the Service Provider has received this Agreement or any other communications related to the Plan translated into a language other than English, and if the meaning of the translated version is different from the English version, the English version will control.
12. Electronic Delivery & Acceptance.  The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means.  The Service Provider hereby
4




Exhibit 10.2

consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.
13. Address for Notices.  Any notice to be given to the Company under the terms of this Agreement shall be addressed to the Company, in care of Stock Plan Administration at Coherent, Inc., 5100 Patrick Henry Drive, Santa Clara, CA 95054 U.S.A., or at such other address as the Company may hereafter designate in writing.
14. Conditions for Issuance of Shares.  The Shares deliverable upon vesting of the RSUs may be either previously authorized but unissued Shares or issued Shares that have been reacquired by the Company.  The Company shall not be required to issue any Shares hereunder prior to fulfillment of all the following conditions: (a) the admission of such Shares to listing on all stock exchanges on which the class of stock is then listed; (b) the completion of any registration or other qualification of such Shares under any law or under the rulings or regulations of the United States Securities and Exchange Commission or any other governmental regulatory body, whether in the United States or elsewhere, which the Company shall, in its absolute discretion, deem necessary or advisable; (c) the obtaining of any approval or other clearance from any governmental agency, which the Company shall, in its absolute discretion, determine to be necessary or advisable; and (d) the lapse of such reasonable period of time following the date of vesting of the RSUs as the Company may establish from time to time for legal or administrative reasons.
15. Plan Governs.  This Agreement is subject to all terms and provisions of the Plan.  In the event of a conflict between one or more provisions of this Agreement and one or more provisions of the Plan, the provisions of the Plan shall govern. 
16. Captions.  Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.
17. Agreement Severable.  In the event that any provision in this Agreement shall be held invalid or unenforceable, such provision shall be severable from, and such invalidity or unenforceability shall not be construed to have any effect on, the remaining provisions of this Agreement.
18. Modifications to the Agreement.  This Agreement (including any appendices attached hereto) constitutes the entire understanding of the parties on the subjects covered.  The Service Provider expressly warrants that he or she is not executing this Agreement in reliance on any promises, representations, or inducements other than those contained herein. Subject to paragraph 21 below, modifications to this Agreement or the Plan can be made only in an express written contract executed by a duly authorized officer of the Company.
19. Governing Law and Venue.  The RSU grant and the provisions of this Agreement will be governed by, and subject to, the internal substantive laws, but not the choice of law rules, of the State of Delaware to the extent permitted by law and not otherwise governed by the laws of the United States. You hereby irrevocably consent to the extent permitted by law to the nonexclusive jurisdiction and venue of the state and federal courts located in the State of Delaware.
20. Appendix.  Notwithstanding any provisions in this Agreement, the RSU grant shall be subject to any additional terms and conditions set forth in the Appendix for the Service Provider’s country.  Moreover, if the Service Provider relocates to one of the countries included in the Appendix, the additional terms and conditions for such country will apply to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons.  The Appendix constitutes part of this Agreement.
21. Imposition of Other Requirements.  The Company reserves the right to impose other requirements on the Service Provider’s participation in the Plan, on the RSUs, and on any Shares acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require the Service Provider to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

By participating in the Plan, the Service Provider agrees to comply with the Company’s policy on insider trading (to the extent that it is applicable to the Service Provider). The Service Provider acknowledges that, depending on his or her country or the broker’s country, or the country in which the Shares are listed, the Service Provider may be subject to insider trading restrictions and/or market abuse laws in applicable jurisdictions, which may affect his or her ability to accept, acquire, sell or attempt to sell, or otherwise dispose of the Shares, rights to Shares (e.g., the RSUs) or rights linked to the value of Shares, during such times as the Service Provider is considered to have “inside information” regarding the Company (as defined by the laws or regulations in applicable jurisdictions, including the United States and, if different, the Service Provider’s country). Local insider trading laws and regulations may prohibit the cancellation or amendment of orders the Service Provider placed before possessing inside information. Furthermore, the Service Provider may be prohibited from (i) disclosing insider information to any third party, including fellow Service Providers (other than on a “need-to-know” basis) and (ii) “tipping” third parties or causing them to otherwise buy or sell securities. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Service Provider acknowledges that it is the Service Provider’s responsibility to comply with any applicable restrictions, and the Service Provider should speak to his or her personal advisor on this matter.
23. Foreign Asset/Account Reporting Requirements. The Service Provider acknowledges that there may be certain foreign asset and/or account reporting requirements which may affect his or her ability to acquire or hold the Shares acquired under the Plan or cash received from participating in the Plan (including from any dividends paid on the Shares) in a brokerage or bank account outside his or her country. The Service Provider may be required to report such accounts, assets or transactions to the tax or other authorities in his or her country. The Service Provider also may be required to repatriate sale proceeds or other funds received as a result of participating in the Plan to his or her country through a designated bank or broker within a certain time from receipt. The Service Provider acknowledges that it is his or her responsibility to be compliant with such regulations.
24. Waiver. The Service Provider acknowledges that a waiver by the Company of breach of any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by the Service Provider or any other Participants.

APPENDIX

Certain capitalized terms used but not defined in this Appendix have the meanings set forth in the Plan, the Notice of Grant and/or the Global Restricted Stock Unit Agreement.
TERMS AND CONDITIONS
This Appendix includes additional terms and conditions that govern the RSUs granted to the Service Provider under the Plan if the Service Provider works and/or resides in one of the countries listed below.  These terms and conditions are in addition to or, if so indicated, in place of, the terms and conditions set forth in the Global Restricted Stock Unit Agreement. If the Service Provider is a citizen or resident of a country other than that in which he or she is currently working and/or residing (or is considered as such for local law purposes) or if the Service Provider transfers his or her service relationship and/or residence to another country after the RSUs are granted, the Company shall, in its discretion, determine to what extent the terms and conditions contained herein shall be applicable to the Service Provider.
NOTIFICATIONS
This Appendix also includes information regarding certain other issues of which the Service Provider should be aware with respect to the Service Provider’s participation in the Plan. Such information is based on the securities, exchange control and other laws in effect in the respective countries as of [_________, 20XX]. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Service Provider not rely on the information contained in this Appendix as the only source of information relating to the consequences of the Service Provider’s participation in the Plan, because the information may be out-of-date at the time the Service Provider vests in the RSUs or sells any Shares acquired upon settlement.
In addition, the information contained in this Appendix is general in nature and may not apply to the Service Provider’s particular situation. As a result, the Company is not in a position to assure the Service Provider of any particular result. Accordingly, the Service Provider should seek appropriate professional advice as to how the relevant laws in the Service Provider’s country may apply to the Service Provider’s individual situation.
If the Service Provider is a citizen or resident of a country other than the one in which the Service Provider is currently residing and/or working, is considered a resident of another country or transfers his or her service relationship and/or residency to another country after the RSUs are granted, the information contained in this Appendix may not be applicable to the Service Provider in the same manner.

Exhibit 10.3

COHERENT, INC.
[2011] EQUITY INCENTIVE PLAN

PERFORMANCE RESTRICTED STOCK UNIT AGREEMENT
1. Grant. The Company hereby grants to the Employee named in the Notice of Grant of Award and Award Agreement (the “Notice of Grant”) an award of Restricted Stock Units (“PRSUs”), as set forth in the Notice of Grant, subject to the terms and conditions in this agreement, including any special terms and conditions for the Employee’s country contained in the appendix attached hereto (the “Appendix” and together with the Performance Restricted Stock Unit Agreement, the “Agreement”) and in the Company’s [2011] Equity Incentive Plan (the “Plan”). Capitalized terms used and not defined in this Agreement shall have the meaning set forth in the Plan.

2. Company’s Obligation. Each PRSU represents the right to receive one Share on settlement as provided in paragraph 5. Unless and until the PRSUs vest pursuant to paragraph 3 and are settled pursuant to paragraph 5, the Employee will have no right to receive Shares under such PRSUs. Prior to actual distribution of Shares pursuant to any vested PRSUs, such PRSUs will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

3. Vesting Schedule; Assumption or Substitution Calculation. The PRSUs shall vest as follows:

[Insert Performance Vesting Schedule]

4. Forfeiture upon Termination as a Service Provider. Notwithstanding any contrary provision of this Agreement or the Notice of Grant, if the Employee terminates service as a Service Provider for any or no reason prior to vesting, the unvested PRSUs awarded by this Agreement will thereupon be forfeited at no cost to the Company. [The accelerated vesting provisions set forth in the Company’s Change of Control and Leadership Change Severance Plan, as amended from time to time shall not apply to these PRSUs.] For purposes of the PRSUs, the Employee’s service will be considered terminated as of the date that the Employee is no longer providing services to the Company or one of its Subsidiaries (regardless of the reason for such termination and whether or not later to be found invalid or in breach of employment laws in the jurisdiction where the Employee is employed), and the Employee’s right to vest in the PRSUs under the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g., the Employee’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Employee is employed); the Company shall have the exclusive discretion to determine when the Employee is no longer providing services for purposes of the PRSUs (including whether the Employee may still be considered to be providing services while on a leave of absence).

5. Settlement After Filing Annual Report and Certification. Any PRSUs that vest in accordance with paragraph 3 will be distributed to the Employee (or in the event of the Employee’s death, to his or her estate) in Shares as soon as practicable on or after the certification of the Compensation and HR Committee of the Board as to the extent to which [Performance Metric] has been achieved and the filing of the Annual Report with the Securities and Exchange Commission.

6. Responsibility for Taxes. The Employee acknowledges and agrees that, regardless of any action taken by the Company or, if different, the Employee’s employer (the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Employee’s participation in the Plan and legally applicable to the Employee (“Tax-Related Items”) is and remains the Employee’s responsibility and may exceed the amount (if any) withheld by the Company or the Employer. The Employee further acknowledges that the Company and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the PRSUs, including, but not limited to, the grant, vesting or settlement of the PRSUs, the receipt of any dividends on Shares,
1




Exhibit 10.3
and the subsequent sale of the Shares; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the PRSUs to reduce or eliminate the Employee’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Employee has become subject to tax in more than one jurisdiction, the Employee acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

        Notwithstanding paragraph 5, prior to any relevant taxable or tax withholding event, as applicable, the Employee will pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, the Company shall withhold in Shares otherwise deliverable to the Employee having a Fair Market Value equal to an amount that satisfies the Tax-Related Items required to be withheld. In the event that such withholding in Shares is problematic under applicable tax, securities, or other laws or has materially adverse accounting consequences, the Employee authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy their withholding obligations, if any, with regard to all Tax-Related Items by one or a combination of the following:

        a. withholding from the Employee’s wages or cash compensation paid to the Employee by the Company and/or the Employer; or

        b.  withholding from proceeds of the sale of Shares acquired upon vesting/settlement of the PRSUs either through a voluntary sale or through a mandatory sale arranged by the Company (on the Employee’s behalf pursuant to this authorization without further consent).

        The Company may withhold or account for Tax-Related Items by considering statutory withholding rates or other withholding rates, including maximum rates applicable in the Employee’s jurisdiction, in which case the Employee may receive a refund of any over-withheld amount in cash and will have no entitlement to the equivalent amount in Shares. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Employee is deemed to have been issued the full number of Shares subject to the vested PRSUs, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items.

        Finally, the Employee shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of the Employee’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares if the Employee fails to comply with the Employee’s obligations in connection with the Tax-Related Items.

7. Rights as Stockholder. Neither the Employee nor any person claiming under or through the Employee will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to the Employee or the Employee’s broker.

8  Acknowledgements. In accepting the grant of PRSUs, the Employee acknowledges, understands and agrees that:

a. the Company (and not the Employee’s employer) is granting the PRSU. The Company will administer the Plan from outside the Employee’s country of residence if the Employee’s country of residence is outside the United States, and the provisions of this Agreement will be governed by, and subject to, the internal substantive laws, but not the choice of law rules, of the State of California;

b. the benefits and rights provided under the Plan, if any, are wholly discretionary and do not constitute regular or periodic payments;
 
c. the Employee is voluntarily participating in the Plan;
2




Exhibit 10.3

d. the PRSUs and the Shares subject to the PRSUs, and the income from and value of same, are not intended to replace any pension rights or compensation;

e. the PRSUs and the Shares subject to the PRSUs, and the income from and value of same, are not part of normal or expected compensation for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, leave-related payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments;

f. unless otherwise agreed with the Company, the PRSUs and the Shares subject to the PRSUs, and the income from and value of same, are not granted as consideration for, or in connection with, services the Employee may provide as a director of a Subsidiary;

g. no claim or entitlement to compensation or damages shall arise from forfeiture of the PRSUs resulting from the termination of the Employee as a Service Provider (for any reason whatsoever; and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Employee is employed);

h. the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty;

i. the grant of PRSUs, and all decisions with respect to any future grant of PRSUs under the Plan, is at the complete discretion of the Company;

j. the grant of the PRSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of Restricted Stock Units, or benefits in lieu of Restricted Stock Units, even if Restricted Stock Units have been granted in the past;

k. the Plan is established voluntarily by the Company, it is discretionary in nature, and it may be modified, amended, suspended, or terminated by the Company at any time, to the extent permitted by the Plan;

l. the grant of PRSUs and the Employee’s participation in the Plan shall not create a right to employment or other service or be interpreted as forming an employment or service contract with the Company and shall not interfere with the ability of the Employer to terminate the Employee’s employment or other service relationship (if any) at any time;

m. unless otherwise provided in the Plan or by the Company in its discretion, the PRSUs and the benefits evidenced by this Agreement do not create any entitlement to have the PRSUs or any such benefits transferred to, or assumed by, another company nor be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and

n. neither the Company, the Employer nor any Subsidiary shall be liable for any foreign exchange rate fluctuation between the Employee’s local currency and the United States Dollar that may affect the value of the PRSUs or of any amounts due to the Employee pursuant to the settlement of the PRSUs or the subsequent sale of any Shares acquired upon settlement.

        9. Data Privacy Information and Consent

a. Data Collection and Usage. The Company and the Employer may collect, process and use certain personal information about the Employee, including, but not limited to, the Employee’s name, home
3




Exhibit 10.3
address, telephone number, email address, date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any Shares or directorships held in the Company, details of all awards granted under the Plan or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in the Employee’s favor (“Data”), for the purposes of implementing, administering and managing the Employee’s participation in the Plan. The legal basis, where required, for the processing of Data is the Employee’s consent.

b. Stock Plan Administration Service Providers. The Company transfers Data to E*TRADE Financial Corporate Services, Inc. and certain of its affiliated companies (“E*TRADE”), an independent service provider based in the United States which is assisting the Company with the implementation, administration and management of the Plan. The Company may select a different service provider or additional service providers and share Data with such other provider serving in a similar manner. The Employee may be asked to agree on separate terms and data processing practices with the service provider, with such agreement being a condition to the ability to participate in the Plan.

c. International Data Transfers. The Company and E*TRADE are based in the United States. The Employee’s country or jurisdiction may have different data privacy laws and protections than the United States. For example, the European Commission has issued a limited adequacy finding with respect to the United States that applies only to the extent companies register for the EU-U.S. Privacy Shield program. The Company has certified under the EU-U.S. Privacy Shield Program and relies on it for its transfer of Data from European Union countries to the U.S. Elsewhere, its legal basis for the transfer of Data, where required, is the Employee’s consent.

d. Data Retention. The Company will hold and use Data only as long as is necessary to implement, administer and manage the Employee’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax and security laws.

e. Voluntariness and Consequences of Consent Denial or Withdrawal. Participation in the Plan is voluntary and the Employee is providing the consents herein on a purely voluntary basis. If the Employee does not consent, or if the Employee later seeks to revoke the consent, his or her salary from or employment with the Employer will not be affected; the only consequence of refusing or withdrawing the consent is that the Company would not be able to grant the Employee awards under the Plan or administer or maintain such awards.

f. Data Subject Rights. The Employee may have a number of rights under data privacy laws in his or her jurisdiction. Depending on where the Employee is based, such rights may include the right to (i) request access to or copies of Data the Company processes, (ii) rectify incorrect Data, (iii) delete Data, (iv) restrict the processing of Data, (v) restrict the portability of Data, (vi) lodge complaints with competent authorities in the Employee’s jurisdiction, and/or (vii) receive a list with the names and addresses of any potential recipients of Data. To receive clarification regarding these rights or to exercise these rights, the Employee can contact his or her local human resources representative.

g. Additional Legal Basis. The Employee understands that the Company may rely on a different legal basis for the collection, processing or transfer of Data in the future and/or request the Employee to provide another data privacy consent. If applicable, upon request of the Company or the Employer, the Employee agrees to provide an executed data privacy consent form to the Company and/or the Employer (or any other agreements or consents that may be required by the Company and/or the Employer) that the Company and/or the Employer may deem necessary to obtain from the Employee for the purpose of administering his or her participation in the Plan in compliance with the applicable data privacy laws, either now or in the future. The Employee understands and agrees that he or she will not be able to participate in the Plan if he or she fails to provide any such consent or agreement requested by the Company and/or the Employer.

13.  Address for Notices. Any notice to be given to the Company under the terms of this Agreement shall be addressed to the Company, in care of Stock Plan Administration at Coherent, Inc., 5100 Patrick Henry Drive, Santa Clara, CA 95054, U.S.A. or at such other address as the Company may hereafter designate in writing.

14. Conditions for Issuance of Shares.

The Company shall not be required to issue any Shares hereunder prior to fulfillment of all the following conditions: (a) the admission of such Shares to listing on all stock exchanges on which the class of stock is then listed; (b) the completion of any registration or other qualification of such Shares under any law or under the rulings or regulations of the United States Securities and Exchange Commission or any other governmental regulatory body, whether in the United States or elsewhere, which the Company shall, in its absolute discretion, deem necessary or advisable; (c) the obtaining of any approval or other clearance from any governmental agency, which the Company shall, in its absolute discretion, determine to be necessary or advisable; and (d) the lapse of such reasonable period of time following the date of settlement of the PRSUs as the Company may establish from time to time for legal or administrative reasons.

15. Plan Governs. This Agreement is subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Agreement and one or more provisions of the Plan, the provisions of the Plan shall govern.

16. Captions. Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

17. Agreement Severable. In the event that any provision in this Agreement shall be held invalid or unenforceable, such provision shall be severable from, and such invalidity or unenforceability shall not be construed to have any effect on, the remaining provisions of this Agreement.

18. Modifications to the Agreement. This Agreement (including any appendices attached hereto) constitutes the entire understanding of the parties on the subjects covered. The Employee expressly warrants that he or she is not executing this Agreement in reliance on any promises, representations, or inducements other than those contained herein. Subject to paragraph 21 below, modifications to this Agreement or the Plan can be made only in an express written contract executed by a duly authorized officer of the Company.

19. Governing Law and Venue. The PRSU grant and the provisions of this Agreement will be governed by, and subject to, the internal substantive laws, but not the choice of law rules, of the State of California.

Exhibit 10.3
For purposes of litigating any dispute that arises directly or indirectly from the relationship of the parties evidenced by the grant or this Agreement, the parties hereby submit to and consent to the exclusive jurisdiction of the State of California and agree that such litigation shall be conducted only in the courts of Santa Clara County, California, or the federal courts for the United States for the Northern District of California, and no other courts, where this grant is made and/or to be performed.

20. Appendix. Notwithstanding any provisions in this Agreement, the PRSU grant shall be subject to any special terms and conditions set forth in the Appendix for the Employee’s country.  Moreover, if the Employee relocates to one of the countries included in the Appendix, the special terms and conditions for such country will apply to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons.  The Appendix constitutes part of this Agreement.

21. Imposition of Other Requirements. The Company reserves the right to impose other requirements on the Employee’s participation in the Plan, on the PRSUs, and on any Shares acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require the Employee to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

22. Insider Trading Restrictions/Market Abuse Laws. By participating in the Plan, the Employee agrees to comply with the Company’s policy on insider trading (to the extent that it is applicable to the Employee). The Employee acknowledges that, depending on his or her country or the broker’s country, or the country in which the Shares are listed, the Employee may be subject to insider trading restrictions and/or market abuse laws in applicable jurisdictions, which may affect his or her ability to accept, acquire, sell or attempt to sell, or otherwise dispose of the Shares, rights to Shares (e.g., the PRSUs) or rights linked to the value of Shares, during such times as the Employee is considered to have “inside information” regarding the Company (as defined by the laws or regulations in applicable jurisdictions, including the United States and, if different, the Employee’s country). Local insider trading laws and regulations may prohibit the cancellation or amendment of orders the Employee placed before possessing inside information. Furthermore, the Employee may be prohibited from (i) disclosing insider information to any third party, including fellow employees or service providers (other than on a “need-to-know” basis) and (ii) “tipping” third parties or causing them to otherwise buy or sell securities. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Employee acknowledges that it is the Employee’s responsibility to comply with any applicable restrictions, and the Employee should speak to his or her personal advisor on this matter.

23. Foreign Asset/ Account Reporting Requirements. The Employee acknowledges that there may be certain foreign asset and/or account reporting requirements which may affect his or her ability to acquire or hold the Shares acquired under the Plan or cash received from participating in the Plan (including from any dividends paid on the Shares) in a brokerage or bank account outside his or her country. The Employee may be required to report such accounts, assets or transactions to the tax or other authorities in his or her country. The Employee also may be required to repatriate sale proceeds or other funds received as a result of participating in the Plan to his or her country through a designated bank or broker within a certain time from receipt. The Employee acknowledges that it is his or her responsibility to be compliant with such regulations.

24. Waiver. The Employee acknowledges that a waiver by the Company of breach of any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by the Employee or any other Participants.
