Notes to Condensed Consolidated Financial Statements (Unaudited)

The condensed consolidated financial statements of II-VI Incorporated (“II-VI” or the “Company”) for the three months ended September 30, 2016 and 2015 are unaudited. In the opinion of management, all adjustments considered necessary for a fair presentation for the periods presented have been included. All adjustments are of a normal recurring nature unless disclosed otherwise. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2016. The consolidated results of operations for the three months ended September 30, 2016 are not necessarily indicative of the results to be expected for the full fiscal year. The June 30, 2016 Condensed Consolidated Balance Sheet information was derived from the Company’s audited financial statements.

Certain amounts from prior periods have been reclassified on the Condensed Consolidated Statements of Cash Flows to conform to the current year presentation relating to Accrued compensation and benefits in Net cash provided by operating activities and Payments in satisfaction of employees’ minimum tax obligations in Net cash provided by (used in) financing activities.

Adopted Pronouncements

In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.  This ASU requires entities to present debt issuance costs in the balance sheet as a direct deduction from the carrying amount of the corresponding debt liability, consistent with debt discounts. The Company adopted ASU 2015-03, as clarified by ASU 2015-15, which did not have a material impact on the Company’s Consolidated Financial Statements other than corresponding reductions to total assets and total liabilities on the Condensed Consolidated Balance Sheets. Prior to adoption, the Company recorded deferred financing costs as Other assets on the Consolidated Balance Sheets. Upon adoption, the Company reclassified these costs as unamortized debt issuance costs that reduce long term debt on the consolidated balance sheet and retrospectively reclassified $0.6 million that were previously presented as deferred financing costs, an asset on the consolidated balance sheet as of June 30, 2016. There was no effect on the consolidated statements of operations as a result of the adoption.

In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. This update requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The adoption of this standard did not have a material effect on the Company’s Consolidated Financial Statements.

In April 2015, the FASB issued ASU 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. This update provides guidance about whether a cloud computing arrangement includes a software license. The adoption of this standard did not have a material effect on the Company’s Consolidated Financial Statements.

In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which affects reporting organizations that are required to evaluate whether they should consolidate certain legal entities. The adoption of this standard did not have a material effect on the Company’s Consolidated Financial Statements.

Pronouncements Currently Under Evaluation

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments in the update provide guidance on eight specific cash flow issues. The update will be effective for the Company’s 2019 fiscal year. Early adoption is permitted. The Company is evaluating the impact of this guidance on the Company’s Consolidated Financial Statements.

In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. The amendments in the update do not change the core principle of the guidance in Topic 606. Rather, the amendments in this update affect only narrow aspects of Topic 606. The update will be effective for the Company’s 2019 fiscal year. The Company is evaluating the impact of this guidance on the Company’s Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This update simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, and clas sification in the statement of cash flows. The standard will be effective for the Company’s 2018 fiscal year. Early adoption is permitted. The Company is evaluating the impact of this guidance on the Company’s Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-07, Investments – Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting. This update eliminates the requirement to retrospectively apply the equity method as a result of an increase in the level of ownership interest. The ASU also requires unrealized holding gains or losses in accumulated other comprehensive income related to an available for sale security that becomes eligible for the equity method to be recognized in earnings when it qualifies for the equity method. The standard will be effective for the Company’s 2018 fiscal year. Early adoption is permitted. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This update requires that a lessee recognize leased assets with terms greater than 12 months on the balance sheet for the rights and obligations created by those leases. The standard will be effective for the Company’s 2020 fiscal year. Early adoption is permitted. The Company is evaluating the impact of this guidance on the Company’s Consolidated Financial Statements.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Recognition and measurement of Financial Assets and Financial Liabilities (Topic 825). This update requires that public entities measure equity investments with readily determinable fair values, at fair value, with changes in their fair value recorded through net income. This ASU also clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity’s other deferred tax assets. The standard will be effective for the Company’s 2018 fiscal year. The Company is evaluating the impact on the Company’s Consolidated Financial Statements.

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This update simplifies the measurement of inventory valuation at the lower of cost or net realizable value.  Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The new inventory measurement requirements will be effective for the Company’s 2018 fiscal year and will replace the current inventory valuation guidance that requires the use of a lower of cost or market framework. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements.

In May 2014, the FASB issued ASU 2014-09: Revenue from Contracts with Customers (Topic 606) which supersedes virtually all existing revenue recognition guidance under U.S. GAAP. The update's core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The update allows for the use of either the retrospective or modified retrospective approach of adoption. On July 9, 2015 the FASB approved a one year deferral of the effective date of the update. The update will be effective for the Company’s 2019 fiscal year. The Company has not yet selected a transition method and is currently evaluating the impact of this guidance on the Company’s Consolidated Financial Statements.

In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements-Going Concern”. This update provides U.S. GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The update is effective for the Company’s 2017 fiscal year. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements.

EpiWorks, Inc.

In February 2016, the Company acquired all the outstanding shares of EpiWorks, Inc. (“EpiWorks”) a privately held company based in Illinois. Under the terms of the merger agreement, the consideration consisted of initial cash paid at the acquisition date of $43.0 million, net of cash acquired and a working capital adjustment of $0.2 million. In addition, the agreement provides up to a maximum of $6.0 million of additional cash earnout opportunities based upon EpiWorks achieving certain agreed upon financial and operational targets for capacity, wafer output and gross margin, which if earned would be payable in the amount of $2.0 million for the achievement of each specific annual target over the next three years. EpiWorks develops and manufactures compound semiconductor epitaxial wafers for applications in optical components, wireless devices and high-speed communication systems. EpiWorks is a

business unit of the Company’s II-VI Laser Solutions operating segment for financial reporting purposes. The Company completed its valuation of the assets of EpiWork s during the quarter ended September 30, 2016.

The following table presents the purchase price at the date of acquisition ($000):

The following table presents the final allocation of the purchase price of the assets acquired and liabilities assumed at the date of acquisition. ($000):

The goodwill of $27.6 million is included in the II-VI Laser Solutions segment and is attributed to the expected synergies and the assembled workforce of EpiWorks. None of the goodwill is deductible for income tax purposes. The fair value of accounts receivable acquired was $2.1 million with the gross contractual amount being $2.1 million. At the time of acquisition, the Company expected to collect all of the accounts receivable.

ANADIGICS, Inc.

In March 2016, the Company acquired all the outstanding shares of ANADIGICS, Inc.,(“ANADIGICS”) a previously publicly traded company based in New Jersey. Under the terms of the merger agreement, the consideration consisted of both a working capital advance of $3.5 million and cash paid of $78.2 million at the acquisition date, net of cash acquired of $2.7 million. ANADIGICS has a 6-inch gallium arsenide wafer fabrication capability allowing for the production of high performance lasers and integrated circuits in high volume. In addition, at the time of the acquisition, ANADIGICS designed and manufactured innovative radiofrequency (RF) solutions for CATV infrastructure, small-cell, WIFI and cellular markets. The Company divested this portion of the business in June 2016. In conjunction with the sale of the RF business, the Company renamed ANADIGICS as II-VI OptoElectronic Devices Division (“OED”). OED is a business unit of the Company’s II-VI Laser Solutions operating segment for financial reporting purposes.

The following table presents the final allocation of the purchase price of the a ssets acquired and liabilities assumed at the date of acquisition ($000):

The goodwill of $48.3 million is included in the II-VI Laser Solutions segment and is attributed to the expected synergies and the assembled workforce of ANADIGICS. None of the goodwill is deductible for income tax purposes. The fair value of accounts receivable acquired was $4.0 million with the gross contractual amount being $4.0 million. At the time of acquisition, the Company expected to collect all of the accounts receivable.

Deferred Income Taxes

In connection with above acquisitions, the Company adopted an accounting policy to apply acquired deferred tax liabilities to pre-existing deferred tax assets before evaluating the need for a valuation allowance for acquired deferred tax assets. During fiscal year 2016, the Company recorded a $36.2 million valuation allowance within purchase accounting as a result of the company incurring a cumulative U.S. three year loss.

Divesture of the RF Business of ANADIGICS

On June 3, 2016, the Company sold the RF business of ANADIGICS that it acquired on March 15, 2016.  The consideration consisted of $45.0 million of cash received at closing, a working capital adjustment of $0.6 million to be received within 60 days after closing and $5.0 million contingent consideration to be earned based upon supplying minimum volumes of wafers to the purchaser over an 18-month period through December 2017. The $5.0 million contingent consideration will be recognized in net earnings when earned and received from the purchaser. During the quarter ended September 30, 2016, the Company recorded $1.25 million of this contingent consideration in Other income, net in the Condensed Consolidated Statement of Earnings. The Company believes the sale of this non-strategic business will allow the Company to focus its financial resources and devote greater attention to the 6-inch wafer fab business. The Company incurred approximately $0.4 million in transaction expenses and recorded an immaterial gain of less than $0.1 million on the sale of the RF business in fiscal year 2016.

The following table presents the carrying value of the assets and liabilities included as part of the disposal of the RF business of ANADIGICS ($000):

Note 1 of the Notes to Consolidated Financial Statements in the Company’s most recent Annual Report on Form 10-K describes the significant accounting policies and methods used in the preparation of the Company’s Consolidated Financial Statements. Management has evaluated goodwill for indicators of impairment and has concluded that there are no indicators of impairment as of September 30, 2016.

The gross carrying amount and accumulated amortization of the Company’s intangible assets other than goodwill as of September 30, 2016 and June 30, 2016 were as follows ($000):

12

Amortization expense recorded on the Company’s intangible assets was $3.2 million and $3.0 million for the three months ended September 30, 2016 and 2015, respectively. The technology and patents are being amortized over a range of 60 to 240 months, with a weighted average remaining life of approximately 98 months. The customer lists are being amortized over a range of approximately 60 to 240 months with a weighted average remaining life of approximately 142 months. The gross carrying amount of trade names includes $14.1 million of acquired trade names with indefinite lives that are not amortized but tested annually for impairment or more frequently if a triggering event occurs. Included in the gross carrying amount and accumulated amortization of the Company’s intangible assets is the effect of foreign currency translation on that portion of the intangible assets relating to the Company’s German and Chinese subsidiaries.

At September 30, 2016, the estimated amortization expense for existing intangible assets for each of the five succeeding fiscal years is as follows ($000):

On July 28, 2016, the Company entered into a Third Amended and Restated Credit Agreement (the “Amended Credit Facility”) which amended the related prior credit facility. The Amended Credit Facility provides for a revolving credit facility of $325 million (increased from $225 million), as well as a $100 million term loan. The term loan is being repaid in consecutive quarterly principal payments on the first business day of each January, April, July and October, with the first payment commencing on October 1, 2016, as follows: (i) twenty consecutive quarterly installments of $5 million and (ii) a final installment of all remaining principal due and payable on the maturity date of July 27, 2021. Amounts borrowed under the revolving credit facility are due and payable on the maturity date. The Amended Credit Facility is unsecured, but is guaranteed by each existing and subsequently acquired or organized wholly-owned domestic subsidiary of the Company. The Company has the option to request an increase to the size of the revolving credit facility in an aggregate additional amount not to exceed $100 million. The Amended Credit Facility has a five-year term through July 27, 2021 and has an interest rate of either a Base Rate Option or a Euro-Rate Option, plus an Applicable Margin, as defined in the agreement governing the Amended Credit Facility. If the Base Rate option is selected for a borrowing, the Applicable Margin is 0.00% to 0.075% and if the Euro-Rate Option is selected for a borrowing, the Applicable Margin is 0.75% to 1.75%. The Applicable Margin is based on the Company’s ratio of consolidated indebtedness to consolidated EBITDA. Additionally, the Credit Facility is subject to certain covenants, including those relating to minimum interest coverage and maximum leverage ratios. As part of entering into the Amended Credit Facility, the Company incurred $1.4 million of new debt issuance costs which are being amortized over the term of the facility. As of September 30, 2016, the Company was in compliance with all financial covenants under its Amended Credit Facility.

The Company’s Yen denominated line of credit is a 500 million Yen (approximately $4.9 million) facility. The Yen line of credit matures in August 2020. The interest rate is equal to LIBOR, as defined in the loan agreement, plus 0.625% to 1.50%. At September 30, 2016 and June 30, 2016, the Company had 300 million Yen borrowed. Additionally, the facility is subject to certain covenants,

13

including those relating to minimum interest coverage and maximum leverage ratios. As of September 30, 2016, the Company was in compliance with all financial covenants under its Yen facility.

The Company had aggregate availability of $178.7 million and $37.7 million under its lines of credit as of September 30, 2016 and June 30, 2016, respectively. The amounts available under the Company’s lines of credit are reduced by outstanding letters of credit. As of September 30, 2016 and June 30, 2016, total outstanding letters of credit supported by these credit facilities was $1.2 million for both periods.

The weighted average interest rate of total borrowings was 2.0% and 1.5% for the three months ended September 30, 2016 and 2015, respectively.

Remaining annual principal payments under the Company’s existing credit facilities as of September 30, 2016 were as follows:

The Company’s year-to-date effective income tax rate at September 30, 2016 and 2015 was 31.7% and 22.2%, respectively. The variations between the Company’s effective tax rate and the U.S. statutory rate of 35.0% were primarily due to the consolidation of the Company’s foreign operations, which are subject to income taxes at lower statutory rates.  

U.S. GAAP clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As of September 30, 2016 and June 30, 2016, the Company’s gross unrecognized income tax benefit was $7.3 million and $5.6 million, respectively. The Company has classified the majority of the uncertain tax positions as noncurrent income tax liabilities, as the amounts are not expected to be paid within one year. If recognized, substantially all of the gross unrecognized tax benefits at September 30, 2016 would impact the effective tax rate. The Company recognizes interest and penalties related to uncertain tax positions in the income tax provision on the Condensed Consolidated Statements of Earnings. The amount of accrued interest and penalties included in the gross unrecognized income tax benefit was $0.9 million and $0.1 million at September 30, 2016 and June 30, 2016, respectively. Fiscal years 2013 to 2017 remain open to examination by the United States Internal Revenue Service, fiscal years 2011 to 2017 remain open to examination by certain state jurisdictions, and fiscal years 2006 to 2017 remain open to examination by certain foreign taxing jurisdictions. The Company’s fiscal years 2012 through 2015 New Jersey state income tax returns and fiscal years 2006 through 2014 Vietnam income tax returns are currently under examination. The Company believes its income tax reserves for these tax matters are adequate.

The following table sets forth the computation of earnings per share for the periods indicated. Weighted average shares issuable upon the exercises of stock options and the release of performance and restricted shares not included in the calculation were approximately 368,000 and 232,000 for the three months ended September 30, 2016 and 2015, respectively, because they were anti-dilutive. ($000 except per share data):

The Company reports its business segments using the “management approach” model for segment reporting. This means that the Company determines its reportable business segments based on the way the chief operating decision maker organizes business segments within the Company for making operating decisions and assessing performance.

The Company reports its financial results in the following three segments: (i) II-VI Laser Solutions, (ii) II-VI Photonics, and (iii) II-VI Performance Products, and the Company’s chief operating decision maker receives and reviews financial information based on these segments.  The Company evaluates business segment performance based upon segment operating income, which is defined as earnings before income taxes, interest and other income or expense. The segments are managed separately due to the market, production requirements and facilities unique to each segment.

The II-VI Laser Solutions segment is located in the U.S., Singapore, China, Germany, Switzerland, Japan, Belgium, the U.K., Italy, South Korea and the Philippines. II-VI Laser Solutions is directed by the President of II-VI Laser Solutions, while each geographic location is directed by a general manager, and is further divided into production and administrative units that are directed by managers. II-VI Laser Solutions designs, manufactures and markets optical and electro-optical components and materials sold under the II-VI Infrared brand name and used primarily in high-power CO ₂ lasers, fiber-delivered beam delivery systems and processing tools and direct diode lasers for industrial lasers sold under the II-VI HIGHYAG and II-VI Laser Enterprise brand names. II-VI Laser Solutions also manufactures compound semiconductor epitaxial wafers for applications in optical components, wireless devices, and high-speed communication systems and manufactures 6-inch gallium arsenide wafers allowing for the production of high performance lasers, vertical cavity surface emitting lasers (“VCSELs”) and integrated circuits in high volume sold under the II-VI EpiWorks and II-VI OptoElectronic Devices Division brand names.  

The II-VI Photonics segment is located in the U.S., China, Vietnam, Germany, Japan, the U.K., Italy, Hong Kong and the Philippines. II-VI Photonics is directed by the President of II-VI Photonics and is further divided into production and administrative units that are directed by managers. II-VI Photonics manufactures crystal materials, optics, microchip lasers and opto-electronic modules for use in optical communication networks and other diverse consumer and commercial applications.  In addition, the segment also manufactures pump lasers, optical amplifiers and micro-optics for optical amplifiers for both terrestrial and submarine applications within the optical communications market.

The II-VI Performance Products segment is located in the U.S., Vietnam, Japan, China, Germany and the Philippines. II-VI Performance Products is directed by the President of II-VI Performance Products, while each geographic location is directed by a general manager. II-VI Performance Products is further divided into production and administrative units that are directed by managers. II-VI Performance Products designs, manufactures and markets infrared optical components and high-precision optical assemblies for

15

military, medical and commercial laser imaging applications.  In addition, the segment designs, manufactures and markets unique engineered materials for thermo-electric and silicon carbide (“SiC”) applications servicing the semiconductor, military and medical markets.

The accounting policies of the segments are the same as those of the Company. The Company’s corporate expenses are allocated to the segments. The Company evaluates segment performance based upon reported segment operating income, which is defined as earnings from continuing operations before income taxes, interest and other income or expense. Inter-segment sales and transfers are eliminated.

The following tables summarize selected financial information of the Company’s operations by segment ($000):

The Board of Directors adopted the II-VI Incorporated Amended and Restated 2012 Omnibus Incentive Plan (the “Plan”), which was approved by the shareholders. The Plan provides for the grant of performance-based cash incentive awards, non-qualified stock options, stock appreciation rights, restricted share awards, restricted share units, deferred share awards, performance share awards and performance share units to employees, officers and directors of the Company. The maximum number of shares of the Company’s common stock authorized for issuance under the Plan is limited to 4,900,000 shares of common stock, not including any remaining shares forfeited under the predecessor plans that may be rolled into the Plan. The Company records share-based compensation expense for these awards in accordance with U.S. GAAP, which requires the recognition of grant-date fair value of share-based compensation in net earnings and over the requisite service period of the individual grantees, which generally equals the vesting period.  The Company accounts for cash-based stock appreciation rights, cash-based restricted share unit awards and cash-based performance share unit awards as liability awards, in accordance with applicable accounting standards.

16

Share-based compensation expense is allocated approximately 20% to cost of goods sold and 80% to selling, general and administrative expense, based on the empl oyee classification of the grantees. Share-based compensation expense for the periods indicated was as follows ($000):

The FASB defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous markets for the asset and liability in an orderly transaction between market participants at the measurement date. The Company estimates fair value of its financial instruments utilizing an established three-level hierarchy in accordance with U.S. GAAP. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date as follows:

The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement. At September 30, 2016, the Company had foreign currency forward contracts recorded at fair value. The fair values of these instruments were measured using valuations based upon quoted prices for similar assets and liabilities in active markets (Level 2) and are valued by reference to similar financial instruments, adjusted for credit risk, restrictions and other terms specific to the contracts. Foreign currency gain related to these contracts was immaterial for the three months ended September 30, 2016. The Company also had a contingent earnout arrangement related to the acquisition of EpiWorks recorded at fair value. The EpiWorks earnout arrangement provides up to a maximum of $6.0 million of additional cash payments based upon EpiWorks achieving certain agreed upon financial and operational targets for capacity, wafer output and gross margin, which if earned would be payable for the achievement of each specific annual target over the next three years. The fair value of the contingent earnout arrangement was measured using valuations based upon other unobservable inputs that are significant to the fair value measurement (Level 3).  

The following table provides a summary by level of the fair value of financial instruments that are measured on a recurring basis for the periods presented ($000):

17

The Company’s policy is to report transfers into and out of Levels 1 and 2 of the fair value hierarchy at fair values as of the beginning of the period in which the transfers occur. There were no transfers in and out of Levels 1 and 2 of the fair value hierarchy during the three months ended September 30, 2016.

The following table presents a reconciliation of the beginning and ending fair value measurements of the Company’s level 3 contingent earnout arrangement related to the acquisition of EpiWorks ($000):
