Notes to Consolidated Financial Statements

(Unaudited)

Note 1 - Basis of Presentation and New Accounting Pronouncements

Basis of Presentation

The accompanying unaudited consolidated financial statements of nLIGHT, Inc. and ~~its~~our wholly owned subsidiaries ~~(Company)~~ have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). The unaudited financial information reflects, in the opinion of management, all adjustments necessary for a fair presentation of financial position, results of operations, stockholders’ equity, and cash flows for the interim periods presented. The results reported for the interim period presented are not necessarily indicative of results that may be expected for the full year. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in ~~the Company's~~our 2020 Annual Report on Form 10-K.

Critical Accounting Policies

~~The Company's~~Our critical accounting policies have not materially changed during the ~~three~~nine months ended ~~March 31,~~September 30, 2021 from those disclosed in ~~its~~our Annual Report on Form 10-K for the year ended December 31, 2020.

New Accounting Pronouncements

ASU 2016-13, ASU 2018-19, ASU 2019-04, ASU 2019-05 and ASU 2020-03

The Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, in June 2016. ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For assets measured at amortized cost, the new standard requires that the income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. ASU 2016-13 was amended in November 2018, April 2019 and March 2020. ~~The Company~~We adopted ASU 2016-13, as amended, on January 1, 2021 on a prospective basis. The adoption did not have a material impact on ~~the Company's~~our financial position, results of operations ~~and~~or cash flows.

ASU 2019-12

The FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, in December 2019. ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ~~The Company~~We adopted ASU 2019-12 on January 1, 2021 on a prospective basis. The adoption did not have a material impact on ~~the Company's~~our financial position, results of operations ~~and~~or cash flows.

Note 2 - Acquisitions

nLIGHT Europe Srl (formerly known as OPI Photonics Srl)

On July 30, 2020, ~~the Company~~we acquired the outstanding shares of OPI Photonics S.r.l. (OPI), an Italian limited liability company, for cash consideration of approximately $1.6 million, of which $0.2 million was paid at closing with the remaining $1.4 million to be paid over the next 24 months. The acquisition price was allocated to the tangible and identified intangible assets acquired and liabilities assumed as of the closing date of the acquisition based upon their respective fair values, and the excess of purchase price over the fair value amounts representing goodwill. The fair values assigned to assets acquired and liabilities assumed were based on management’s best estimates and assumptions as of the reporting date and are considered preliminary. Changes to amounts recorded as assets or liabilities may result in corresponding adjustments to goodwill. Pro forma financial information has not been provided for the purchase as it was not material to ~~the Company’s~~our overall financial position.

During the ~~three~~nine months ended ~~March 31,~~September 30, 2021, accrued acquisition consideration of $0.6 million, including contingent consideration of $0.3 million, was paid to the sellers of OPI.

Note 5 - Fair Value of Financial Instruments

The carrying amounts of certain of ~~the Company’s~~our financial instruments, including cash equivalents, accounts receivable, ~~restricted cash,~~prepaid expenses and other current assets, accounts payable and accrued liabilities are shown at cost which approximates fair value due to the short-term nature of these instruments. The fair value of ~~the Company’s~~our term and revolving loans ~~with Pacific Western Bank, also described in Note 12,~~ approximates the carrying value due to the variable market rate used to calculate interest payments.

~~The Company does~~We do not have any other significant financial assets or liabilities that are measured at fair value.

Fair value is defined 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 market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:

•Level 1 Inputs: Observable inputs, such as quoted prices (unadjusted) in active markets for identical assets or liabilities at the measurement date.

•Level 2 Inputs: Observable inputs, other than Level 1 prices, such as quoted prices in active markets for similar assets and liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3 Inputs: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

~~The Company’s~~Our financial instruments that are carried at fair value consist of Level 1 assets which include highly liquid investments and bank drafts classified as cash equivalents. ~~The Company's~~Our fair value hierarchy for ~~its~~our financial instruments consists of cash equivalents as follows (in thousands):

Note 6 - Inventory

Inventory is stated at the lower of average cost (principally standard cost, which approximates actual cost on a first-in, first-out basis) and net realizable value. Inventory includes raw materials and components that may be specialized in nature and subject to obsolescence. On a quarterly basis, we review inventory quantities on hand in comparison to our past consumption, recent purchases, and other factors to determine what inventory quantities, if any, may not be sellable. Based on this analysis, we write down the affected inventory value for estimated excess and obsolescence charges. At the point of loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.

Note 11 - Line of Credit Facility

We have a $40.0 million revolving line of credit (LOC) with Pacific Western Bank dated September 24, 2018, which is secured by our assets.

On September 24, 2021, we amended the LOC to extend the maturity date to September 24, 2024, remove LIBOR references and update the financial covenants.

The LOC agreement contains restrictive and financial covenants and bears an unused credit fee of 0.20% on an annualized basis. The interest rate on the LOC is based on the Prime rate minus a margin based on our liquidity levels. No amounts were outstanding under the LOC at September 30, 2021 and we were in compliance with all covenants.

Note 12 - Commitments and Contingencies

Leases

See Note 13.

~~Credit Facilities~~

The Company has a $40.0 million revolving line of credit (LOC) with Pacific Western Bank which is secured by its assets and expires in September 2021. Interest on the LOC is based primarily on the London Interbank Offered Rate (LIBOR), or an alternative rate such as the Prime rate, plus or minus, respectively, a margin based on certain liquidity levels. The loan agreement contains restrictive and financial covenants and bears an unused credit fee of 0.20% on an annualized basis. As of March 31, 2021, 0 amounts were outstanding under the LOC, and the Company was in compliance with all covenants under the loan agreement.

~~Contractual Commitments and Purchase Obligations~~

As of March 31, 2021, the Company's purchase obligations and other contractual obligations have increased by approximately $6.5 million for new and modified operating leases, primarily related to U.S. operations. There have been no other material changes to the Company's purchase obligations and other contractual obligations from those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2020.

Legal Matters

From time to time, ~~the Company~~we may be subject to legal proceedings and claims in the ordinary course of business. As of ~~March 31,~~September 30, 2021, and as of the filing of this Quarterly Report on Form 10-Q, ~~the Company was~~we were not involved in any material legal proceedings.

Note 13 - Leases

~~Adoption of ASC 842~~

~~The Company adopted ASU 2016-02,~~ ~~Leases (Topic 842)~~ and related amendments, using the modified transition approach with an effective date of January 1, 2020. The modified transition approach permits a company to use its effective date as the date of initial application to apply the standard to its leases, and, therefore, not restate comparative prior period financial information. Consequently, prior period financial information is not updated, and the disclosures required under the new standard will not be provided for dates and periods prior to January 1, 2020. The adoption of theWe lease ~~standard did not have any effect on our previously reported consolidated financial statements and did not result in a cumulative catch-up adjustment to opening equity.~~

~~Transition Practical Expedients and Elections~~

The standard provides several optional practical expedients in transition. The Company elected the ‘package of practical expedients,’ which permits it to not reassess, under the new standard, the Company's prior conclusions about lease identification, lease classification and initial direct costs. The Company did not elect the use-of-hindsight or the practical expedient pertaining to land easements; the latter not being applicable to it. The new standard also provides practical expedients for an entity’s ongoing accounting. The Company elected the short-term lease recognition exemption; for those leases that qualify, the Company will not recognize a right-of-use asset or lease liability, and this includes not recognizing right-of-use assets or lease liabilities for existing short-term leases of those assets in transition. The Company also elected the practical expedient to not separate lease and non-lease components for all its leases.

~~Lease Accounting~~

~~The Company leases~~ real estate space under non-cancelable operating lease agreements for commercial and industrial ~~space, as well as its corporate headquarters located in Vancouver, Washington.~~space. Facilities-related operating leases have remaining terms of 0.2 to ~~14.2~~13.7 years, and some leases include options to extend up to 15 years. Other leases for automobiles, manufacturing and office and computer equipment have remaining lease terms of ~~0.2~~0.8 to ~~5.2~~4.7 years. These leases are primarily operating leases; financing leases are not material. ~~The Company~~We did not include any renewal options in ~~its~~our lease terms for calculating the lease liabilities as ~~the Company is~~we are not reasonably certain itwe will exercise the options at this time.

~~Note 14 - Income Taxes~~

~~Income Tax Provision~~

To calculate the interim tax provision, at the end of each interim period the Company estimates the annual effective tax rate and applies that to its ordinary quarterly earnings. The effect of changes in the enacted tax laws or rates is recognized in the interim period in which the change occurs. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and judgments including, but not limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in foreign jurisdictions, permanent differences between book and tax amounts, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained, or the tax environment changes.

The Company’s effective tax rate for the three months ended March 31, 2021 and 2020 differs from the U.S. statutory rate due to the U.S. and China valuation allowance, foreign income taxed at local statutory rates, and accrued withholding taxes. For the three months ended March 31, 2021 and 2020, the Company reported U.S. and China pre-tax losses. The Company has not yet been able to establish a sustained level of profitability in the U.S. and China, or other sufficient significant positive evidence, to conclude that its U.S. and China deferred tax assets are more likely than not to be realized. Therefore, the Company continues to maintain a valuation allowance against its U.S. and China deferred tax assets.

We record income tax expense for taxes in our foreign jurisdictions including Finland, Italy and Korea. We also record tax expense for uncertain tax positions taken and associated penalties and interest. We consider all available evidence, both positive and negative, in assessing the extent to which a valuation allowance should be applied against our deferred tax assets. Due to the uncertainty with respect to their ultimate realizability in the U.S. and China, we continue to maintain a full valuation allowance in both jurisdictions as of ~~March 31,~~September 30, 2021.

Liquidity and Capital Resources

We had cash and cash equivalents of ~~$185.6~~$165.6 million and $102.3 million as of ~~March 31,~~September 30, 2021 and December 31, 2020, respectively.

Table of Contents

We believe our existing sources of liquidity will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months. However, we may need to raise additional capital to expand the commercialization of our products, fund our operations and further our research and development activities. Our future capital requirements may vary materially from period to period and will depend on many factors, including the timing and extent of spending on research and development efforts, the expansion of sales and marketing activities, the continuing market acceptance of our products and ongoing investments to support the growth of our business. We may in the future enter into arrangements to acquire or invest in complementary businesses, services, technologies and intellectual property rights. From time to time, we may explore additional financing sources which could include equity, equity‑linked and debt financing arrangements.

Net Cash Provided by ~~(Used in)~~ Operating Activities

During the ~~three~~nine months ended ~~March 31,~~September 30, 2021, net cash provided by operating activities was ~~$4.1~~$2.7 million, which was primarily driven by ~~$6.1~~non‑cash expenses totaling $43.4 million related to depreciation and amortization, stock-based compensation, and other items, a $9.7 million increase in accounts payable and a $0.9 million increase in accrued and other long-term liabilities. These items were partially offset by our net loss of $20.9 million and increases of $16.2 million in inventory and $4.6 million in accounts receivable. The increase in inventory was driven primarily by an expected increase in future period sales. The increase in accounts receivable was attributable to the increase in revenue and timing of shipments during the quarter. The increase in accounts payable was attributable to the increase in inventory and the timing of vendor payments.

During the nine months ended September 30, 2020, net cash provided by operating activities was $14.7 million, which was primarily driven by $16.4 million of net loss reported for the period, and ~~non‑cash~~non-cash adjustments of ~~$12.5~~$28.7 million related to depreciation and amortization, stock-based compensation, and other items. These items were partially offset by increases of ~~$4.4~~$6.4 million in inventory and $1.4 million in accounts payable, and a decrease in prepaid expenses and other current assets of $2.2 million. The increase in inventory was driven by an expected increase in future period sales, and the increase in accounts payable was driven by an increase in inventory purchases and timing of vendor payments. The decrease in prepaid expenses and other current assets was primarily due to reduction in our contract assets and collection of import duty reclaims.

During the three months ended March 31, 2020, net cash used in operating activities was $1.1 million, which was primarily driven by $7.5 million of net loss reported in the period, and non-cash adjustments of $7.7 million related to depreciation and amortization, stock-based compensation, and other items. These items were partially offset by increases of $3.6 million in inventory and $4.6$10.6 million in accounts payable. The increase in inventory supported new product introductions, decreased customer lead times and increased safety stock. The increase in accounts payable was primarily driven by timing of vendor payments.

Net Cash Used in Investing Activities

During the ~~three~~nine months ended ~~March 31,~~September 30, 2021, net cash used in investing activities was ~~$3.5~~$14.2 million, primarily resulting from ~~$3.1~~$13.6 million of capital expenditures related to investments in manufacturing equipment and improvements to our corporate facility.

During the ~~three~~nine months ended ~~March 31,~~September 30, 2020, net cash used in investing activities was ~~$15.5~~$20.3 million, primarily resulting from ~~$15.2~~$19.4 million of capital expenditures related to the acquisition of commercial property and other investments in manufacturing equipment for our worldwide operations.

Net Cash Provided by Financing Activities

During the ~~three~~nine months ended ~~March 31,~~September 30, 2021, net cash provided by financing activities was ~~$82.9~~$75.1 million, which was primarily driven by our follow-on public offering of ~~$82.8~~$82.4 million, net of offering ~~costs.~~costs, and $1.7 million of proceeds from stock options exercises and employee stock program purchases, partially offset by $8.3 million of withholding tax payments related to the vesting of stock awards.

Off-Balance Sheet Arrangements

Since inception, we have not had any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or for another contractually narrow or limited purpose.

Our inability or failure to do so could materially adversely affect our business, financial condition and results of operations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

For financial market risks related to changes in interest rates and foreign currency exchange rates, reference is made to Item 7A, “Quantitative and Qualitative Disclosures about Market Risk,” contained in Part II of our Annual Report on Form 10-K for the year ended December 31, 2020. Our exposure to market risk has not changed materially since December 31, 2020.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and our chief financial officer, have evaluated our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, our chief executive officer and our chief financial officer have concluded that, as of such date, our disclosure controls and procedures were, in design and operation, effective.

Changes in Internal Control over Financial Reporting

Our chief executive officer and our chief financial officer did not identify any changes in our internal control over financial reporting in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act during the three months ended ~~March 31,~~September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We acquired OPI Photonics S.r.l. (OPI) on July 30, 2020 and have not yet completed the process of integrating the acquired business's internal controls over financial reporting into our overall internal controls over financial reporting processes.

Limitations on the Effectiveness of Internal Control

Control systems, including ours, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control systems’ objectives are being met. Further, the design of any control systems must reflect the fact that there are resource constraints, and the benefits of all controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple error or mistake. Control systems can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based, in part, on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business, but cannot assure you that such improvements will be sufficient to provide us with effective internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We may, from time to time, be party to litigation and subject to claims incident to the ordinary course of business. As our company matures, we may become party to an increasing number of litigation matters and claims. The outcome of litigation and claims cannot be predicted with certainty, and the resolution of these matters could materially adversely affect our business, financial condition, results of operations and growth prospects.

There have been no material changes to the legal proceedings disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.

ITEM 1A. RISK FACTORS

For risk factors related to our business, reference is made to Item 1A, "Risk Factors," contained in Part I of our Annual Report on Form 10-K for the year ended December 31, 2020. There have been no material changes to the risk factors disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.
