Notes to the Condensed Consolidated Financial Statements (Unaudited)

(dollars in thousands, except per-share and share amounts)

Note 1. Basis of Presentation

Organization

The ExOne Company (“ExOne”) is a corporation organized under the laws of the state of Delaware. ExOne was formed on January 1, 2013, when The Ex One Company, LLC, a Delaware limited liability company, merged with and into a Delaware corporation, which survived and changed its name to The ExOne Company (the “Reorganization”). As a result of the Reorganization, The Ex One Company, LLC became ExOne, the common and preferred interest holders of The Ex One Company, LLC became holders of common stock and preferred stock, respectively, of ExOne, and the subsidiaries of The Ex One Company, LLC became the subsidiaries of ExOne. The condensed consolidated financial statements include the accounts of ExOne, its wholly-owned subsidiaries, ExOne Americas LLC (United States); ExOne GmbH (Germany); ExOne Property GmbH (Germany); ExOne KK (Japan); and through December 2018, ExOne Italy S.r.l (Italy). Collectively, the consolidated group is referred to as the “Company”.

The Company filed a registration statement on Form S-3 (No. 333-223690) with the Securities and Exchange Commission (“SEC”) on March 15, 2018. The purpose of the Form S-3 was to register, among other securities, debt securities. Subsidiaries of the Company are co-registrants with the Company (“Subsidiary Guarantors”), and the registration statement registered guarantees of debt securities by one or more of the Subsidiary Guarantors. The Subsidiary Guarantors are 100% owned by the Company and any guarantees by the Subsidiary Guarantors will be full and unconditional. There have been no transactions undertaken subject to the Form S-3 since its initial filing.

Basis of Presentation

The condensed consolidated financial statements of the Company are unaudited. The condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, considered necessary by management to fairly state the results of operations, financial position and cash flows of the Company. All material intercompany transactions and balances have been eliminated in consolidation. The results reported in these condensed consolidated financial statements are not necessarily indicative of the results that may be expected for the entire year. The December 31, 2018 condensed consolidated balance sheet data was derived from the audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”). This Quarterly Report on Form 10-Q should be read in connection with the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, which includes all disclosures required by GAAP.

The preparation of these condensed consolidated financial statements requires the Company to make certain judgments, estimates and assumptions regarding uncertainties that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosure of contingent assets and liabilities. Areas that require significant judgments, estimates and assumptions include accounting for accounts receivable (including the allowance for doubtful accounts); inventories (including the allowance for slow-moving and obsolete inventories); product warranty reserves; contingencies; income taxes (including the valuation allowance on certain deferred tax assets and liabilities for uncertain tax positions); equity-based compensation (including the valuation of certain equity-based compensation awards issued by the Company); and testing for impairment of long-lived assets (including the identification of asset groups by management, estimates of future cash flows of identified asset groups and fair value estimates used in connection with assessing the valuation of identified asset groups). The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Certain amounts relating to contract liabilities – net of current portion ($527) in the accompanying condensed consolidated balance sheet at December 31, 2018, have been reclassified from other noncurrent liabilities to conform to current period presentation, following the adoption of Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2014-09 (further described below).

Certain amounts relating to the lessor current portion of net investment in sales-type leases ($302) and lessor net investment in sales-type leases – net of current portion ($1,351) in the accompanying condensed consolidated balance sheet at December 31, 2018, have been reclassified from accounts receivable and other noncurrent assets, respectively, to conform to current period presentation following the adoption of FASB ASU 2016-02 (further described below).

Related to the reclassifications further described above, amounts within the condensed statement of consolidated cash flows for the six months ended June 30, 2018 associated with these changes have also been reclassified to conform to current period presentation.

Recently Adopted Accounting Guidance

On January 1, 2019, the Company adopted FASB ASU 2014-09, “Revenue from Contracts with Customers.” This ASU created a comprehensive framework for all entities in all industries to apply in the determination of when to recognize revenue and, therefore, supersedes virtually all existing revenue recognition requirements and guidance. This framework is expected to provide a consistent

6

and comparable methodology for revenue recognition. The core principle of the guidanc e 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. To achieve this principle, an entity should apply the following steps: identify the contract(s) with a customer, identify the performance obligations in the contract(s), determine the transaction price, allocate the transaction price to the performance obligations in the contract(s), and recognize revenue when, or as, the entity satisfies a performance obligation. The Company adopted this guidance using the modified retrospective approach. Revenue from the Company’s sale of three-dimensional (“3D”) printing machines and 3D printed and other products, materials and services continues to generally be recognized when the related machines, products or materials are delivered or accepted by the Company’s customers or as the related services are performed by the Company. As such, the adoption of this guidance did not have a material impact on the Company’s financial position or results of operations. The Company has included the enhanced disclosures required by this guidance in its condensed consolidated financial statements (Note 5).

On January 1, 2019, the Company adopted FASB ASU 2016-02, “Leases.” This ASU requires lessees to recognize a right-of-use asset and lease liability on the consolidated balance sheet for leases classified as operating leases. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize a right-of-use asset and lease liability. Additionally, when measuring assets and liabilities arising from a lease, optional payments should be included only if the lessee is reasonably certain to exercise an option to extend the lease, exercise a purchase option, or not exercise an option to terminate the lease. A right-of-use asset represents an entity’s right to use the underlying asset for the lease term, and a lease liability represents an entity’s obligation to make lease payments. Currently, an asset and liability only are recorded for leases classified as capital leases (financing leases). The measurement, recognition, and presentation of expenses and cash flows arising from leases by a lessee remains the same. In connection with the adoption of this guidance, the Company has completed an assessment resulting in an accumulation of all of its leasing arrangements and has validated the information for accuracy and completeness. Upon adoption of the new lease guidance, management recorded a right-of-use asset and lease liability, each in the amount of approximately $400, on the Company’s consolidated balance sheet for various types of operating leases, including certain machinery and other equipment and vehicles. This amount is equivalent to the aggregate future minimum lease payments on a discounted basis. The Company has also elected to apply the package of transitional practical expedients of the new lease guidance by allowing the Company to not: (1) reassess if expired or existing contracts are, or contain, leases; (2) reassess lease classification for any expired or existing leases; and (3) reassess initial direct costs for any existing leases. Additionally, in July 2018, the FASB issued guidance to provide for an alternative transition method to the new lease guidance, whereby an entity can choose to not reflect the impact of the new lease guidance in the prior periods included in its consolidated financial statements. The Company has utilized this alternative transition method in connection with its adoption on January 1, 2019. The Company has included the enhanced disclosures required by this guidance in its condensed consolidated financial statements (Note 11).

On January 1, 2019, the Company adopted FASB ASU 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments.” This ASU is intended to reduce diversity in practice in how certain cash receipts and payments are presented and classified in the statement of consolidated cash flows. The standard provides guidance in a number of situations including, among others, settlement of zero-coupon bonds, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, and distributions received from equity method investees. The ASU also provides guidance for classifying cash receipts and payments that have aspects of more than one class of cash flows. The adoption of this ASU did not have an effect on the consolidated financial statements of the Company .

Recently Issued Accounting Guidance

The Company considers the applicability and impact of all ASUs issued by the FASB. Recently issued ASUs not listed below either were assessed and determined to be not applicable or are currently expected to have no impact on the consolidated financial statements of the Company.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses.” This ASU added a new impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses. The CECL model applies to most debt instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not have a minimum threshold for recognition of impairment losses and entities will need to measure expected credit losses on assets that have a low risk of loss. These changes become effective for the Company on January 1, 2020. Management is currently evaluating the potential impact of these changes on the consolidated financial statements of the Company.

Note 2. Liquidity

The Company has incurred a net loss in each of its annual periods since its inception. As shown in the accompanying condensed statement of consolidated operations and comprehensive loss, the Company incurred a net loss of approximately $3,789 and $8,285 for the three months and six months ended June 30, 2019, respectively. At June 30, 2019, the Company had approximately $5,462 in unrestricted cash and cash equivalents.

7

Since its inception the Company has received cumulative unrestricted net proceeds from the sale of its common stock (through its initial public offering and subsequent secondary offerings) of approximately $ 168,361 to fund its operations. In March 2018, the Company entered i nto a three-year , $ 15,000 revolving credit facility with a related party (Note 13) to provide additional funding for working capital and general corporate purposes. In June 2018, the Company initiated a 2018 global cost realignment program focused on a red uction in the Company’s production overhead costs and operating expenses in an effort to drive efficiency in its operations and preserve capital.

Management believes that the Company’s existing capital resources will be sufficient to support the Company’s operating plan. If management anticipates that the Company’s actual results will differ from its operating plan, management believes it has sufficient capabilities to enact cost savings measures to preserve capital (in addition to the costs savings measures associated with the Company’s 2018 global cost realignment program further described above). The Company may also seek to raise additional capital to support its growth through additional debt, equity or other alternatives (including asset sales) or a combination thereof.

Foreign currency translation adjustments consist of the effect of translation of functional currency financial statements (denominated in the euro and Japanese yen) to the reporting currency of the Company (United States dollar) and certain long-term intercompany transactions between subsidiaries for which settlement is not planned or anticipated in the foreseeable future.

There were no tax impacts related to income tax rate changes and no amounts were reclassified to earnings for either of the periods presented.

Note 4. Loss Per Share

The Company presents basic and diluted loss per common share amounts. Basic loss per common share is calculated by dividing net loss available to common stockholders by the weighted average number of common shares outstanding during the applicable period. Diluted loss per common share is calculated by dividing net loss available to common stockholders by the weighted average number of common shares and common equivalent shares outstanding during the applicable period.

As the Company incurred a net loss during each of the three months and six months ended June 30, 2019 and 2018, basic average common shares outstanding and diluted average common shares outstanding were the same because the effect of potential shares of common stock, including stock options (608,787 – 2019 and 536,635 – 2018) and unvested restricted stock issued (96,264 – 2019 and 52,502 – 2018), was anti-dilutive.

The information used to compute basic and diluted net loss per common share was as follows for the periods indicated:

Note 5. Revenue

The Company derives revenue from the sale of 3D printing machines and 3D printed and other products, materials and services. Revenue is recognized when the Company satisfies its performance obligation(s) under a contract (either implicit or explicit) by transferring the promised product or service to a customer either when (or as) the customer obtains control of the product or service. A

8

performance obligation is a promise in a contract to transfer a distinct product or service to a customer. A contract’s t ransaction price is allocated to each distinct performance obligation.

Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or providing services. As such, revenue is recorded net of returns, allowances, customer discounts, and incentives. Sales, value add, and other taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from revenue) basis. Shipping and handling costs are included in cost of sales.

Certain of the Company’s contracts with customers provide for multiple performance obligations. Sales of 3D printing machines may also include optional equipment, materials, replacement components and services (installation, training and other services, including maintenance services and/or an extended warranty). Certain other contracts have a single performance obligation, as the promise to transfer products or services is not separately identifiable from other promises in the contract and, therefore, not distinct. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using the Company’s best estimate of stand-alone selling price for each distinct product or service in the contract, which is generally based on an observable price.

The Company’s revenue from products is transferred to customers at a point in time. The Company’s contracts for 3D printing machines generally include substantive customer acceptance provisions. Revenue under these contracts is recognized when customer acceptance provisions have been satisfied. For all other product sales, the Company recognizes revenue at the point in time in which the customer obtains control of the product, which is generally when product title passes to the customer upon delivery. In limited cases, title does not transfer and revenue is not recognized until the customer has received the products at its physical location.

The Company’s revenue from service arrangements includes deferred maintenance contracts and extended warranties that can be purchased at the customer’s option. The Company generally provides a standard one-year warranty on the Company’s 3D printing machines, which is considered an assurance type warranty, and not considered a separate performance obligation (Note 10). Revenue associated with deferred maintenance contracts is generally recognized at a point in time when the related services are performed where sufficient historical evidence indicates that the costs of performing the related services under the contract are not incurred on a straight-line basis, with such revenue recognized in proportion to the costs expected to be incurred. Revenue associated with extended warranties is generally recognized over time on a straight-line basis over the related contract period.

The Company’s revenue from service arrangements includes contracts with the Federal government under fixed-fee, cost reimbursable and time and materials arrangements (certain of which may have periods of performance greater than one year). Revenue under these contracts is generally recognized over time using an input measure based upon labor hours incurred and provisional rates provided under the contracts. As such, the nature of these contracts may give rise to variable consideration, primarily based upon completion of the Company’s annual Incurred Cost Submission filing as required by the Federal government. Historically, amounts associated with variable consideration have not been significant.

The Company’s revenue from service arrangements includes certain research and development services. Revenue under research and development service contracts is generally recognized over time using an output measure, specifically units or parts delivered, based upon certain customer acceptance and delivery requirements. Revenue recognized over time using an output measure is not significant.

The following table summarizes the Company’s revenue by product group for the periods indicated:

Revenue from 3D printing machines includes leasing revenue whereby the Company is the lessor of 3D printing machines to its customers. Leasing revenue is accounted for under ASU 2016-02 (Note 11).

The timing of revenue recognition, billings and cash collections results in billed receivables, unbilled receivables (contract assets) and deferred revenue and customer prepayments (contract liabilities) in the accompanying condensed consolidated balance sheet. The Company considers a number of factors in its evaluation of the creditworthiness of its customers, including past due amounts, past payment history, and current economic conditions. For 3D printing machines, the Company’s terms of sale vary by transaction. To reduce credit risk in connection with 3D printing machine sales, the Company may, depending upon the circumstances, require customers to furnish letters of credit or bank guarantees or to provide advanced payment (either partial or in full). For 3D printed and other products and materials, the Company’s terms of sale generally require payment within 30 to 60 days after delivery, although the Company also recognizes that longer payment periods are customary in certain countries where it transacts business. Service arrangements are generally billed in accordance with specific contract terms and are typically billed in advance or in proportion to

9

performance of the related services. There were no other significant changes in contract liabilities du ring the three months or six months ended June 30 , 2019. Contract assets are not significant.

For the six months ended June 30, 2019, the Company recognized revenue of approximately $1,573 related to contract liabilities at January 1, 2019.

At June 30, 2019, the Company had approximately $23,100 of remaining performance obligations (including contract liabilities), which is also referred to as backlog, of which approximately $19,700 was expected to be fulfilled during the twelve months following such date.

The Company has elected to apply the practical expedient associated with incremental costs of obtaining a contract, and as such, sales commission expense is generally expensed when incurred because the amortization period would be one year or less. These costs are recorded within selling, general and administrative expenses.

Accounts receivable are reported at their net realizable value. The Company’s estimate of the allowance for doubtful accounts related to trade receivables is based on the Company’s evaluation of customer accounts with past-due outstanding balances or specific accounts for which it has information that the customer may be unable to meet its financial obligations. Based upon review of these accounts, and management’s analysis and judgment, the Company records a specific allowance for that customer’s accounts receivable balance to reduce the outstanding receivable balance to the amount expected to be collected. The allowance is re-evaluated and adjusted periodically as additional information is received that impacts the allowance amount reserved. At June 30, 2019 and December 31, 2018, the allowance for doubtful accounts was approximately $73   and $225, respectively. During the three months ended June 30, 2019 and 2018, the Company recorded net recoveries for bad debts of approximately $77 and $46, respectively. During the six months ended June 30, 2019 and 2018, the Company recorded net recoveries for bad debts of approximately $150 and $37, respectively.

Note 6. Restructuring

In December 2017 the Company committed to a plan to consolidate certain of its 3D printing operations from its Desenzano del Garda, Italy facility into its Gersthofen, Germany facility. These actions were taken as part of the Company’s efforts to optimize its business model and maximize its facility utilization. During the three months ended December 31, 2017, the Company recorded a charge of approximately $72 split between cost of sales ($19) and selling, general and administrative expense ($53) associated with involuntary employee terminations related to this plan. During the three months ended March 31, 2018, the Company recorded an additional charge of approximately $245 associated with other exit costs ($17) and asset impairments ($228) related to this plan. During the three months ended June 30, 2018, the Company recorded an additional charge of approximately $13 associated with asset impairments related to this plan. In addition, during the three months ended June 30, 2018, the Company recorded a gain from disposal of certain property and equipment of approximately $51 (recorded to cost of sales in the accompanying condensed statement of consolidated operations and comprehensive loss). Charges associated with other exit costs recorded during the six months ended June 30, 2018 were recorded to cost of sales in the accompanying condensed statement of consolidated operations and comprehensive loss. Charges associated with asset impairments recorded during the three and six months ended June 30, 2018 were recorded to cost of sales as a component of depreciation expense in the accompanying condensed statement of consolidated operations and comprehensive loss. Other exit costs relate to the remaining facility rent due under a non-cancellable operating lease following the cessation of operations at the facility in January 2018. Asset impairment charges relate to certain leasehold improvements associated with the exited facility and other equipment which was abandoned by the Company. There are no additional charges expected to be incurred associated with this plan in future periods. The Company settled all amounts associated with involuntary employee terminations and other exit costs (remaining facility rent payments) during 2018.

Note 7. Impairment

During the three months ended June 30, 2019, as a result of continued operating losses and cash flow deficiencies, the Company identified a triggering event requiring a test for the recoverability of long-lived assets held and used at the asset group level. Assessing the recoverability of long-lived assets held and used requires significant judgments and estimates by management.

For purposes of testing long-lived assets for recoverability, the Company operates as three separate asset groups: United States, Europe and Japan. In assessing the recoverability of long-lived assets held and used, the Company determined the carrying amount of long-lived assets held and used to be in excess of the estimated future undiscounted net cash flows of the related assets. The Company proceeded to determine the fair value of its long-lived assets held and used, principally through use of the market approach. The Company’s use of the market approach included consideration of market transactions for comparable assets. Management concluded that the fair value of long-lived assets held and used exceeded their carrying value, and as such, no impairment loss was recorded .    

A significant decrease in the market price of a long-lived asset, adverse change in the use or condition of a long-lived asset, adverse change in the business climate or legal or regulatory factors impacting a long-lived asset and continued operating losses and cash flow deficiencies associated with a long-lived asset, among other indicators, could cause a future assessment to be performed which may

10

result in an impairment of long-lived assets held and used, resulting in a material adverse effect on the fin ancial position and results of operations of the Company.

Restricted cash at June 30, 2019 and December 31, 2018 includes approximately $1,284 and $1,044, respectively, associated with cash collateral required by a German bank for short-term financial guarantees issued by ExOne GmbH in connection with certain commercial transactions requiring security (Note 12). Restricted cash at June 30, 2019 and December 31, 2018 includes approximately $506 and $504, respectively, associated with cash collateral required by a United States bank to offset certain short-term, unsecured lending commitments associated with the Company’s corporate credit card program. Each of the balances described are considered legally restricted by the Company.

Raw materials and components consist of consumable materials and component parts and subassemblies associated with 3D printing machine manufacturing and support activities. Work in process consists of 3D printing machines and other products in varying stages of completion. Finished goods consist of 3D printing machines and other products prepared for sale in accordance with customer specifications.

At June 30, 2019 and December 31, 2018, the allowance for slow-moving and obsolete inventories was approximately $4,149 and $4,143, respectively, and has been reflected as a reduction to inventories (principally raw materials and components).

During the three months ended June 30, 2018, the Company recorded a charge of approximately $561 to cost of sales in the accompanying condensed statement of consolidated operations and comprehensive loss attributable to certain industrial microwave inventories based on a sustained absence of demand for such curing solutions and a decision by the Company to discontinue future manufacturing of such industrial microwaves.

Note 10. Product Warranty Reserves

Substantially all of the Company’s 3D printing machines are covered by a standard twelve- month warranty. Generally, at the time of sale, a liability is recorded (with an offset to cost of sales) based upon the expected cost of replacement parts and labor to be incurred over the life of the standard warranty. Expected cost is estimated using historical experience for similar products. The Company periodically assesses the adequacy of the product warranty reserves based on changes in these factors and records any necessary adjustments if actual experience indicates that adjustments are necessary. Future claims experience could be materially different from prior results because of the introduction of new, more complex products, a change in the Company’s warranty policy in response to industry trends, competition or other external forces, or manufacturing changes that could impact product quality. In the event that the Company determines that its current or future product repair and replacement costs exceed estimates, an adjustment to these reserves would be charged to cost of sales in the period such a determination is made.

The following table summarizes changes in product warranty reserves, which amounts were reflected in accrued expenses and other current liabilities in the accompanying condensed consolidated balance sheet for the periods indicated:

11

Note 11. Leases

Lessee

The Company leases machinery and other equipment and vehicles under operating lease arrangements (with initial terms greater than twelve months), expiring in various years through 2026. In addition, the Company leases certain equipment and vehicles under finance (previously capital) lease arrangements, which are not significant.

For all operating lease arrangements (with the exception of short-term lease arrangements), the Company presents at the commencement date: a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term.

The Company has elected, as a practical expedient, not to separate non-lease components from lease components, and instead account for each separate component as a single lease component for all lease arrangements, as lessee. In addition, the Company has elected, as a practical expedient, not to apply lease recognition requirements to short-term lease arrangements, generally those with a lease term of less than twelve months, for all classes of underlying assets. In determination of the lease term, the Company considers the likelihood of lease renewal options and lease termination provisions. As a result, lease payments under these short-term lease arrangements are recognized in the accompanying condensed statement of consolidated operations and comprehensive loss on a straight-line basis over the lease term.  

The Company uses its incremental borrowing rate in determining the present value of lease payments, as the implicit rate of the lease arrangements is generally not readily determinable.

Certain of the Company’s operating lease arrangements are with related parties under common control (Note 18). Lease cost under operating lease agreements with related parties, included within short-term lease cost below, was approximately $12 and $24 for the three months and six months ended June 30, 2019.

Future minimum lease payments of operating lease arrangements (with initial terms greater than twelve months) at June 30, 2019, were approximately as follows:

For the three months and six months ended June 30, 2019, lease cost under operating lease arrangements was approximately $98 (including $47 relating to short-term lease arrangements) and $211 (including $112 relating to short-term lease arrangements), respectively.

Supplemental information related to operating lease arrangements (with initial terms greater than twelve months) was as follows at and for the six months ended June 30, 2019:

12

Lessor

The Company leases machinery and equipment to customers (principally 3D printing machines and related equipment) under lease arrangements classified as either operating leases or sales-type leases. The Company’s operating lease arrangements have initial terms generally ranging from one to five years, certain of which may contain extension or termination clauses, or both. Such operating lease arrangements also generally include a purchase option to acquire the related machinery and equipment at the end of the lease term for either a fixed amount as determined at inception, or a subsequently negotiated fair market value. At June 30, 2019, the Company estimated that the total fair market value significantly exceeded the related net book value of the machinery and equipment held under the Company’s operating lease arrangements. The Company’s sales-type lease arrangements generally include transfer of ownership at the end of the lease term, and as such, the Company’s net investment in sale-type lease arrangements presented in the Company’s accompanying condensed consolidated balance sheet generally does not include an amount of unguaranteed residual value.

The Company has elected, as a practical expedient, not to separate non-lease components from lease components, and instead account for each separate component as a single lease component for all lease arrangements, as lessor. Sales, value add, and other taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from lease income) basis. In determination of the lease term, the Company considers the likelihood of lease renewal options and lease termination provisions. Additionally, certain of the Company’s lease arrangements do not qualify as sale-type leases as collectability is not reasonably assured.

The Company recognized the following components under operating and sales-type lease arrangements in the accompanying condensed statement of consolidated operations and comprehensive loss for the periods indicated:

The Company’s net investment in sales-type leases consisted of the following as of the dates indicated:

13

Future minimum lease payments of non-cancellable operating and sales-type lease arrangements at June 30, 2019, were approximately as follows:

As previously disclosed under the prior lease accounting standard, minimum future rentals under non-cancellable operating and sales-type lease arrangements at December 31, 2018, were approximately as follows:

Note 12. Contingencies and Commitments

Contingencies

On March 1, 2018, the Company’s ExOne GmbH subsidiary notified Voxeljet AG that it had materially breached a 2003 Patent and Know-How Transfer Agreement and asserted its rights to set-off damages as a result of the breaches against the annual license fee due from the Company under the agreement. At this time, the Company cannot reasonably estimate a contingency, if any, related to this matter.

The Company and its subsidiaries are subject to various litigation, claims, and proceedings which have been or may be instituted or asserted from time to time in the ordinary course of business. Management does not believe that the outcome of any pending or threatened matters will have a material adverse effect, individually or in the aggregate, on the financial position, results of operations or cash flows of the Company.

Commitments

In the normal course of its operations, ExOne GmbH issues short-term financial guarantees and letters of credit to third parties in connection with certain commercial transactions requiring security. ExOne GmbH maintains a credit facility with a German bank which provides for various short-term financings in the form of overdraft credit, financial guarantees, letters of credit and collateral security for commercial transactions for an aggregate of approximately $1,400 (€1,300). In addition, ExOne GmbH may use the credit facility for short-term, fixed-rate loans in minimum increments of approximately $100 (€100) with minimum terms of at least 30 days. The overdraft credit interest rate is fixed at 10.2% while the interest rate associated with commercial transactions requiring security (financial guarantees, letters of credit or collateral security) is fixed at 1.75%. The credit facility has an indefinite term and is subject to cancellation by either party at any time upon repayment of amounts outstanding or expiration of commercial transactions requiring security. There is no commitment fee associated with the credit facility. There are no negative covenants associated with the credit facility. The credit facility has been guaranteed by the Company. At June 30, 2019 and December 31, 2018, there were no outstanding borrowings in the form of overdraft credit or short-term loans under the credit facility. At June 30, 2019, total outstanding financial

14

guarantees and letters of credit issued by ExOne GmbH under the credit facility were approximately $ 1,284 (€ 1,129 ) with expiration dates ranging from July 201 9 through November 2019. At December 31, 2018, total outstanding financial guarantees and letters of credit issued by ExOne GmbH un der the credit facility were approximately $1, 044 (€9 12 ).

In addition to amounts issued by ExOne GmbH under the credit facility, from time to time, ExOne GmbH enters into separate agreements with the same German bank for additional capacity for financial guarantees and letters of credit associated with certain commercial transactions requiring security. Terms of the separate agreements are substantially similar to those of the existing credit facility. At June 30, 2019, ExOne GmbH had a singular financial guarantee outstanding under a separate agreement for approximately $91 (€80) with an expiration date of February 2023. Related to this separate agreement, the requirement for cash collateral was waived by the German bank as it also represents the counterparty in the related transaction.

Note 13. Related Party Revolving Credit Facility

On March 12, 2018, ExOne and its ExOne Americas LLC and ExOne GmbH subsidiaries, as guarantors (collectively, the “Loan Parties”), entered into a Credit Agreement and related ancillary agreements with LBM Holdings, LLC (“LBM”), a company controlled by S. Kent Rockwell, who was the Executive Chairman of the Company (a related party) at such date and is currently Chairman of the Board of Directors (the “Board”) of the Company, relating to a $15,000 revolving credit facility (the “LBM Credit Agreement”) to provide additional funding for working capital and general corporate purposes. The LBM Credit Agreement provides for a term of three years (through March 12, 2021) and bears interest at a rate of one month LIBOR plus an applicable margin of 500 basis points (approximately 7.4% and 7.5%   at June 30, 2019 and December 31, 2018, respectively). The LBM Credit Agreement requires a commitment fee of 75 basis points, or 0.75%, on the unused portion of the facility, payable monthly in arrears. In addition, an up-front commitment fee of 125 basis points, or 1.25% (approximately $188), was required at closing. Borrowings under the LBM Credit Agreement are required to be in minimum increments of $1,000. ExOne may terminate or reduce the credit commitment at any time during the term of the LBM Credit Agreement without penalty. ExOne may also make prepayments against outstanding borrowings under the LBM Credit Agreement at any time without penalty. Borrowings under the LBM Credit Agreement have been collateralized by the accounts receivable, inventories and machinery and equipment of the Loan Parties. At June 30, 2019 and December 31, 2018, the total estimated value of collateral was in significant excess of the maximum borrowing capacity under the LBM Credit Agreement.

The LBM Credit Agreement contains several affirmative covenants including prompt payment of liabilities and taxes; maintenance of insurance, properties, and licenses; and compliance with laws. The LBM Credit Agreement also contains several negative covenants including restricting the incurrence of certain additional debt; prohibiting future liens (other than permitted liens); prohibiting investment in third parties; limiting the ability to pay dividends; limiting mergers, acquisitions, and dispositions; and limiting the sale of certain property and equipment of the Loan Parties. The LBM Credit Agreement does not contain any financial covenants. The LBM Credit Agreement also contains events of default, including, but not limited to, cross-default to certain other debt, breaches of representations and warranties, change of control events and breaches of covenants.

LBM was determined to be a related party based on common control by S. Kent Rockwell. Accordingly, the Company does not consider the LBM Credit Agreement indicative of a fair market value lending. Prior to execution, the LBM Credit Agreement was reviewed and approved by the Audit Committee of the Board and subsequently by a sub-committee of independent members of the Board. At the time of execution of the LBM Credit Agreement, the $15,000 in available loan proceeds was deposited into an escrow account with an unrelated, third party financial institution acting as escrow agent pursuant to a separate Escrow Agreement by and among the parties. Loan proceeds held in escrow are available to the Company upon its submission to the escrow agent of a loan request. Such proceeds will not be available to LBM until payment in-full of the obligations under the LBM Credit Agreement and termination of the LBM Credit Agreement. Payments of principal and other obligations will be made to the escrow agent, while interest payments will be made directly to LBM. Provided there exists no potential default or event of default, the LBM Credit Agreement and Escrow Agreement prohibit any acceleration of repayment of any amount outstanding under the LBM Credit Agreement and prohibit termination of the LBM Credit Agreement or withdrawal from escrow of any unused portion of the available loan proceeds under the credit facility, by LBM.

There have been no borrowings by the Company under the LBM Credit Agreement from March 12, 2018 (inception) through June 30, 2019.

The Company incurred approximately $265 in debt issuance costs associated with the LBM Credit Agreement (including the aforementioned up front commitment fee paid at closing to LBM).

During the three months and six months ended June 30, 2019, the Company recorded interest expense relating to the LBM Credit Agreement of approximately $50 and $100, respectively. Included in interest expense for the three months and six months ended June 30, 2019 was approximately $22 and $44, respectively, associated with amortization of debt issuance costs. At June 30, 2019 and December 31, 2018, remaining debt issuance costs were approximately $151 and $195, respectively (of which approximately $88 was included in prepaid expenses and other current assets for both periods and approximately $63 and $107, respectively, was included in other noncurrent assets in the accompanying condensed consolidated balance sheet). Also included in interest expense for the three months and six months ended June 30, 2019 was approximately $28 and $56, respectively, associated with the commitment fee on the

15

unused portion of the revolving credit facility . At June 30, 2019 and December 31, 2018, approximately $9 and $10, respectively, was included in accounts payable in the accompanying condensed consolidated balance sheet. Amounts payable to LBM at June 30, 2019 and December 2018 were settled by the Company in July 2019 and January 2019, respectively .

During the three months and six months ended June 30, 2018, the Company recorded interest expense relating to the LBM Credit Agreement of approximately $49 and $59, respectively.

Note 14. Income Taxes

The provision (benefit) for income taxes for the three months ended June 30, 2019 and 2018 was approximately $99 and $18, respectively. The provision (benefit) for income taxes for the six months ended June 30, 2019 and 2018 was approximately ($701) and $35, respectively. The Company has completed a discrete period computation of its provision (benefit) for income taxes for each of the periods presented. The discrete period computation was required as a result of jurisdictions with losses before income taxes for which no tax benefit can be recognized and an inability to generate reliable estimates for results in certain jurisdictions as a result of inconsistencies in generating net operating profits (losses) in those jurisdictions.

The effective tax rate for the three months ended June 30, 2019 and 2018 was 2.7% (provision on a loss) and 0.2% (provision on a loss), respectively. The effective tax rate for the six months ended June 30, 2019 and 2018 was 7.8% (benefit on a loss) and 0.2% (provision on a loss), respectively. For the three months ended June 30, 2019 and 2018, the effective tax rate differs from the United States federal statutory rate of 21.0% primarily due to net changes in valuation allowances for the periods. For the six months ended June 30, 2019, the effective tax rate differs from the United States federal statutory rate of 21.0% primarily due to the reversal of previously recorded liabilities for uncertain tax positions (further described below) and net changes in valuation allowances for the period. For the six months ended June 30, 2018, the effective tax rate differs from the United States federal statutory rate of 21.0% primarily due to net changes in valuation allowances for the periods.

The Company has provided a valuation allowance for its net deferred tax assets as a result of the Company not generating consistent net operating profits in jurisdictions in which it operates. As such, any benefit from deferred taxes in any of the periods presented has been fully offset by changes in the valuation allowance for net deferred tax assets. The Company continues to assess its future taxable income by jurisdiction based on recent historical operating results, the expected timing of reversal of temporary differences, various tax planning strategies that the Company may be able to enact in future periods, the impact of potential operating changes on the business and forecast results from operations in future periods based on available information at the end of each reporting period. To the extent that the Company is able to reach the conclusion that its net deferred tax assets are realizable based on any combination of the above factors in a single, or in multiple, taxing jurisdictions, a reversal of the related portion of the Company’s existing valuation allowances may occur.

The Company has a liability for uncertain tax positions related to certain intercompany transactions.

A reconciliation of the beginning and ending amount of unrecognized tax benefits (including accrued interest and penalties) was as follows for the periods indicated:

The Company includes interest and penalties related to income taxes as a component of the provision (benefit) for income taxes in the accompanying condensed statement of consolidated operations and comprehensive loss. There were no such interest or penalties included in the provision (benefit) for income taxes for any of the periods presented.

At December 31, 2018, there was approximately $820 in unrecognized tax benefits (including accrued interest and penalties) that if recognized would affect the annual effective tax rate. Such amounts were included in accrued expenses and other current liabilities in the accompanying condensed consolidated balance sheet at December 31, 2018. There were no such unrecognized tax benefits at June 30, 2019.

16

At December 31, 2018, the Company’s ExOne GmbH (2010-2013) and ExOne Property GmbH (2013) subsidiaries were under examination by local taxing authorities in Germany. In January 2019, this examination was concluded by the local taxing authorities in Germany without significant adjustment to previously established tax positions. As a result, during the three months ended March 31, 2019, the Company recorded a re versal of certain of its previously recorded liabilities for uncertain tax positions of approximately $1,075, of which approximately $257 was offset against net operating loss carryforwards .

Note 15. Equity-Based Compensation

On January 24, 2013, the Board adopted the 2013 Equity Incentive Plan (the “Plan”). In connection with the adoption of the Plan, 500,000 shares of common stock were reserved for issuance pursuant to the Plan, with automatic increases in such reserve available each year annually on January 1 from 2014 through 2023 equal to the lesser of 3.0% of the total outstanding shares of common stock as of December 31 of the immediately preceding year, or a number of shares of common stock determined by the Board, provided that the maximum number of shares authorized under the Plan could not exceed 1,992,241 shares, subject to certain adjustments. The maximum number of shares authorized under the Plan was reached on January 1, 2017. At June 30, 2019, 865,506 shares remained available for future issuance under the Plan.

Stock options and restricted stock issued by the Company under the Plan are generally subject to service conditions resulting in annual vesting on the anniversary of the date of grant over a period typically ranging between one and three years. Certain stock options and restricted stock issued by the Company under the Plan vest immediately upon issuance. Stock options issued by the Company under the Plan have contractual lives which expire over a period typically ranging between five and ten years from the date of grant subject to continued service to the Company by the participant.

On February 7, 2018, the Compensation Committee of the Board adopted the 2018 Annual Incentive Program (the “Program”) as a subplan under the Plan. The Program provided an opportunity for performance-based compensation to senior executive officers of the Company, among others. The target annual incentive for each Program participant was expressed as a percentage of base salary and was conditioned on the achievement of certain financial goals (as approved by the Compensation Committee of the Board) or a combination of financial and non-financial goals. The Compensation Committee of the Board retained negative discretion over amounts payable under the Program.

The following table summarizes the total equity-based compensation expense recognized by the Company for the periods indicated:

At June 30, 2019, total future compensation expense related to unvested awards yet to be recognized by the Company was approximately $541 for stock options and $498 for restricted stock. Total future compensation expense related to unvested awards yet to be recognized by the Company is expected to be recognized over a weighted-average remaining vesting period of approximately 1.2 years.

The fair value of stock options granted was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions for the periods indicated:

17

For certain stock option awards in which the expected term of the award is less than the period for which the Company has been publicly traded, volatility is estimated based on the historical volatility of the Company. For certain stock option awards in which the expected term of the award exceeds the period for which the Company has been publicly traded, volatility is estimated based on the historical volatilities of certain peer group companies. The average risk-free rate is based on a weighted average yield curve of risk-free interest rates consistent with the expected term of the awards. Expected dividend yield is based on historical dividend data as well as future expectations. Expected term is calculated using the simplified method as the Company does not have sufficient historical exercise experience upon which to base an estimate.

The activity for stock options was as follows for the periods indicated:

At June 30, 2019, intrinsic value associated with stock options exercisable and expected to vest was approximately $289 and $251, respectively. The weighted average remaining contractual term of both stock options exercisable and expected to vest at June 30, 2019, was approximately 4.3 years. Stock options with an aggregate intrinsic value of approximately $326 were exercised by employees during the six months ended June 30, 2019, resulting in proceeds to the Company from the exercise of stock options of approximately $263 (of which, at June 30, 2019, approximately $91 remained unsettled). The Company received no income tax benefit related to these exercises. There were no stock option exercises during the six months ended June 30, 2018.

The activity for restricted stock was as follows for the periods indicated:

Restricted stock that vested during the six months ended June 30, 2019 and 2018, had a fair value of approximately $356 and $205, respectively.

During the six months ended June 30, 2019, the Company made cash payments for taxes of approximately $68 relating to the net settlement of certain equity-based awards. There were no cash payments for taxes or net settlement of equity-based awards during the six months ended June 30, 2018.

Note 16. Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities which are required to be recorded at fair value, the Company considers the principal or most advantageous market in which the Company would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk.

18

The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categoriza tion within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
