Notes to Consolidated Financial Statements
Note 1 - Basis of Presentation and New Accounting Pronouncements
Basis of Presentation
The accompanying unaudited consolidated financial statements of nLIGHT, Inc. and our wholly-owned subsidiaries 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 our Annual Report on Form 10-K for the year ended December 31, 2023.
Critical Accounting Policies
Our critical accounting policies have not materially changed during the nine months ended September 30, 2024, from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023.
New Accounting Pronouncements
ASU 2023-07
In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, Improvements to Reportable Segment Disclosures. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We will adopt ASU 2023-07 in the fourth quarter of 2024 using a retrospective transition method. We are
currently evaluating the impact of this guidance on our consolidated financial statements.
ASU 2023-09
In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. This ASU requires enhanced jurisdictional and other disaggregated disclosures for the effective tax rate reconciliation and income taxes paid and is effective for fiscal years beginning after December 15, 2024. This ASU requires additional disclosures and, accordingly, we do not expect the adoption of ASU 2023-09 to have a material effect on our financial position, results of operations or cash flows.
Note 2 - Revenue
We recognize revenue upon transferring control of products and services and the amounts recognized reflect the consideration we expect to be entitled to receive in exchange for these products and services. We consider customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. As part of our consideration of the contract, we evaluate certain factors, including the customer's ability to pay (or credit risk). For each contract, we consider the promise to transfer products, each of which is distinct, as the identified performance obligations.
We allocate the transaction price to each distinct product based on its relative standalone selling price. Master sales agreements or purchase orders from customers could include a single product or multiple products. Regardless, the contracted price with the customer is agreed to at the individual product level outlined in the customer contract or purchase order. We do not bundle prices; however, we do negotiate with customers on pricing for the same products based on a variety of factors (e.g., level of contractual volume). We have concluded that the prices negotiated with each individual customer are representative of the stand-alone selling price of the product.
We often receive orders with multiple delivery dates that may extend across several reporting periods. We allocate the transaction price of the contract to each delivery based on the product standalone selling price and invoice for each scheduled delivery upon shipment or delivery and recognize revenues for such delivery at that point, when transfer of control has occurred. As scheduled delivery dates are generally within one year, under the optional exemption provided by ASC 606-10-50-14a, revenues allocated to future shipments of partially completed contracts are not disclosed as performance obligations for point in time revenue. Further, we recognize, over time, revenue as per ASC 606-10-55-18 (invoice practical expedient) for our cost plus contracts and, accordingly, elect not to disclose

Table of Contents
information related to those performance obligations under ASC 606-10-50-14b. As of September 30, 2024, we had $10 million of performance obligations relating to firm fixed price contracts that did not qualify for the aforementioned disclosure exemptions. We expect to recognize 50% of these performance obligations by the end of 2024 and the remainder by the end of 2025.
Rights of return generally are not included in customer contracts. Accordingly, product revenue is recognized upon transfer of control at shipment or delivery, as applicable. Rights of return are evaluated as they occur.
Revenues recognized at a point in time consist of sales of semiconductor lasers, fiber lasers and other related products. Revenues recognized over time generally consist of development arrangements that are structured based on our costs incurred. For long-term contracts, we estimate the total expected costs to complete the contract and recognize revenue based on the percentage of costs incurred at period end. Typically, revenue is recognized over time using costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying our performance obligations. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Contract costs include labor, materials, subcontractors costs, other direct costs, and indirect costs applicable on government and commercial contracts.
Contract estimates are based on various assumptions to project the outcome of future events that may span several
years. These assumptions include labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials, the performance of subcontractors, and the availability and timing of funding from the customer. Billing under these arrangements generally occurs within one month of the costs being incurred or as milestones are reached.
The following tables represent a disaggregation of revenue from contracts with customers for the periods presented (in thousands):

Our contract assets and liabilities were as follows (in thousands):

| Balance Sheet Classification |  | As of
|  | September 30, 2024 |  | December 31, 2023
Contract assets | Prepaid expenses and other current assets |  | $ | 8,802 |  |  | $ | 7,298 |
Contract liabilities | Deferred revenues and other long-term liabilities |  | 5,769 |  |  | 6,368 |

Contract assets generally consist of revenue recognized on an over-time basis where revenue recognition has been met, but the amounts are billed and collected in a subsequent period. In our services contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals, which is generally monthly, or upon the achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets recorded in prepaid expenses and other current assets on the Consolidated Balance Sheets. However, we sometimes receive advances or deposits from our customers before revenue is recognized, resulting in contract liabilities recorded in deferred revenues on the Consolidated Balance Sheets. Contract liabilities are not a significant financing component as they are generally utilized to pay for contract costs within a one-year period or are used to ensure the customer meets contractual requirements. These assets and liabilities are reported on the Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period. For our product revenue, we generally receive cash payments subsequent to satisfying the performance obligation via delivery of the product, resulting in billed accounts receivable. For our contracts, there are no significant gaps between the receipt of payment and the transfer of the associated goods and services to the customer for material amounts of consideration.
During the three and nine months ended September 30, 2024, we recognized revenue of $43 thousand and $4.3 million that was included in the deferred revenues balance at the beginning of the period as the performance obligations under the associated agreements were satisfied.
Note 3 - Concentrations of Credit and Other Risks
The following customers accounted for 10% or more of our revenues for the periods presented:

| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2024 |  | 2023 |  | 2024 |  | 2023 |
U.S. Government* | 12% |  | 16% |  | 15% |  | 17% |
Raytheon Technologies | (1) |  | (1) |  | 10% |  | (1) |
KORD Technologies | 19% |  | (1) |  | 14% |  | (1) |

*Excludes sales to customers who sell our products and services exclusively to the U.S. Government
(1) Represents less than 10% of total revenues.
Financial instruments that potentially expose us to concentrations of credit risk consist principally of receivables from customers. As of September 30, 2024 and December 31, 2023, two customers accounted for a total of 22% and 24%, respectively, of net customer receivables. No other customers accounted for 10% or more of net customer receivables at either date.
Note 4 - Marketable Securities
Marketable securities consist primarily of highly liquid investments with original maturities of greater than 90 days when purchased. Our marketable securities are considered available-for-sale as they represent investments that are available to be sold for current operations. As such, they are included as current assets on our Consolidated Balance Sheets at fair value with unrealized gains and losses included in accumulated other comprehensive loss. Any unrealized gains and losses that are considered to be other-than-temporary are recorded in other income, net on our Consolidated Statements of Operations. Realized gains and losses on the sale of marketable securities are determined using the specific-identification method and recorded in other income, net on our Consolidated Statements of Operations.
Realized gains were $1.1 million and $2.5 million for the three and nine months ended September 30, 2024, respectively. Unrealized losses were $0.2 million and immaterial for the three and nine months ended September

Table of Contents
30, 2024, respectively. These unrealized gains are considered temporary and are reflected in the Consolidated Statements of Comprehensive Loss. Realized gains were $0.8 million and $1.7 million for the three and nine months ended September 30, 2023, respectively. Unrealized gains were immaterial for the three months ended September 30, 2023 and $0.3 million for the nine months ended September 30, 2023.
See Note 5 for additional information.
Note 5 - Fair Value of Financial Instruments
The carrying amounts of certain of our financial instruments, including cash equivalents, accounts receivable, 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 our term and revolving loans approximates the carrying value due to the variable market rate used to calculate interest payments.
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.
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 and marketable securities.
Our fair value hierarchy for our financial instruments was as follows (in thousands):

Cash Equivalents
The fair value of cash equivalents is determined based on quoted market prices for similar or identical securities.
Marketable Securities
We classify our marketable securities as available-for-sale and value them utilizing a market approach that uses observable inputs without applying significant judgment.
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.
Inventory consisted of the following (in thousands):

Legal Matters
On March 25, 2022, Lumentum Operations LLC (Lumentum) filed a complaint against nLIGHT, Inc. and certain of its employees in the U.S. District Court for the Western District of Washington. The complaint alleges that Lumentum is the partial or full owner of certain of our patents and requests corresponding relief from the court. We are vigorously defending against Lumentum’s allegations. Loss in this matter is not probable or reasonably estimable and, as such, no loss contingency has been recorded.
From time to time, we may be subject to various other legal proceedings and claims in the ordinary course of business. As of September 30, 2024 we believe these matters will not have a material adverse effect on our consolidated financial statements.
Note 13 - Leases
We lease real estate space under non-cancelable operating lease agreements for commercial and industrial space. Facilities-related operating leases have remaining terms of 0.1 to 10.7 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 0.1 to 4.1 years. These leases are primarily operating leases; financing leases are not

Overview
nLIGHT, Inc. is a leading provider of high‑power semiconductor and fiber lasers for industrial, microfabrication, and aerospace and defense applications. Headquartered in Camas, Washington, we design, develop, and manufacture the critical elements of our lasers, and believe our vertically integrated business model enables us to rapidly introduce innovative products, control our costs and protect our intellectual property.
We operate in two reportable segments—Laser Products and Advanced Development —and we serve three primary end-markets—Industrial, Microfabrication, and Aerospace and Defense. Sales of our semiconductor lasers, fiber lasers, fiber amplifiers, and other directed energy laser products are included in the Laser Products segment, while revenue earned from research and development contracts are included in the Advanced Development segment.
Revenues decreased to $151.2 million in the nine months ended September 30, 2024 compared to $158.0 million in the same period of 2023 due primarily to decreased sales in the Laser Products segment. We generated a net loss of $35.8 million for the nine months ended September 30, 2024 compared to a net loss of $28.4 million for the same period of 2023.

Factors Affecting Our Performance
Demand for our Semiconductor and Fiber Laser Solutions
Our revenue growth depends on market demand and achievement of design wins for our semiconductor and fiber lasers. We consider a design win to occur when a customer notifies us that it has selected one of our products to be incorporated into a product or system under development by such customer. For the foreseeable future, our operations will continue to depend upon capital expenditures by customers in the Industrial and Microfabrication markets, which, in turn, depend upon the demand for these customers’ products or services. In addition, in the Aerospace and Defense market, our business depends in large part on continued investment in laser technology by the U.S. government and its allies, and our ability to continue to successfully develop leading technology in this area and commercialize that technology in the future.
Demand for our products also fluctuates based on market cycles, continuously evolving industry supply chains, trade and tariff terms, as well as evolving competitive dynamics in each of our end-markets. Erosion of average selling prices, or ASPs, of established products is typical in our industry, and the ASPs of our products generally decrease as our products mature. We may also negotiate discounted selling prices from time to time with certain customers that purchase higher volumes, or to penetrate new markets or applications. Historically, we have been able to offset decreasing ASPs by introducing new and higher value products, increasing the sales of our existing products, expanding into new applications and reducing our product and manufacturing costs. Although we anticipate further increases in product volumes and the continued introduction of new and higher value products, ASP reduction may cause our revenues to decline or grow at a slower rate.
Technology and New Product Development
We invest heavily in the development of our semiconductor, fiber laser, directed energy, and laser-sensing technologies to provide solutions to our current and future customers. We anticipate that we will continue to invest in research and development to achieve our technology and product roadmap. Our product development is targeted to specific sectors of the market where we believe the performance of our products provides a significant benefit to our customers. We believe our close coordination with our customers regarding their future product requirements enhances the efficiency of our research and development expenditures.
Manufacturing Costs and Gross Margins
Our product gross profit, in absolute dollars and as a percentage of revenues, is impacted by our product sales mix, sales volumes, changes in ASPs, production volumes, the corresponding absorption of manufacturing overhead expenses, the cost of purchased materials, production costs and manufacturing yields. Our product sales mix can affect gross profits due to variations in profitability related to product configurations and cost profiles, customer volume pricing, availability of competitive products in various markets, and new product introductions, among other factors. We have invested heavily in U.S.-based manufacturing capabilities in the last several years. Capacity utilization affects our gross margin because we have a high fixed cost base due to our vertically integrated business model. Increases in sales and production volumes drive favorable absorption of fixed costs, improved manufacturing efficiencies and lower production costs. Gross margins may fluctuate from period to period depending on product mix and the level of capacity utilization.
Our Advanced Development gross profit varies with the type and terms of contracts, contract volume, project mix, changes in the estimated cost of projects at completion, and successful execution on projects during the period. Most of our Advanced Development contracts have historically been structured as cost plus fixed fee due to the technical complexity of the research and development services, but we also perform work under fixed price contracts where gross margin can change from period to period based on the estimated cost of the project at completion.
Seasonality
Our quarterly revenues can fluctuate with general economic trends, the timing of capital expenditures by our customers, holidays, and general economic trends. In addition, as is typical in our industry, we tend to recognize a larger percentage of our quarterly revenues in the last month of the quarter, which may impact our working capital trends.

The increase in Laser Products gross margin for the three months ended September 30, 2024 compared to the same period of 2023 was driven primarily by positive changes in sales mix and increases in ASPs in the Aerospace and Defense market. Our average gross margins on sales for the Industrial market have been lower than those for the Microfabrication and Aerospace and Defense markets. The decrease in Laser Products gross margin for the nine months ended September 30, 2024 compared to same period of 2023, was driven by the impact of lower production volumes on fixed manufacturing costs due to the decrease in overall customer demand, partially offset by positive changes in sales mix.
The decrease in Advanced Development gross margin for the three months ended September 30, 2024 compared to the same period in 2023 was driven by changes in the composition of research and development contracts and a increase in the estimated cost at completion on a significant fixed priced contract in the third quarter of 2024. The increase in Advanced Development gross margin for the nine months ended September 30, 2024 compared to the same periods in 2023 was primarily the result of changes in the composition of research and development contracts. The nine month period ended September 30, 2024 included more revenue from fixed priced contracts that carried higher average gross margins than cost-plus fixed fee contracts during the period.

The increase in research and development expense for the three months ended September 30, 2024 compared to the same period in 2023 was primarily attributable to an increase in employee compensation costs and project-related spending, offset partially by a decrease in stock-based compensation of $0.6 million. The decrease in research and development expense for the nine months ended September 30, 2024 compared to the same period in 2023 was driven by a decrease in stock-based compensation of $1.7 million, offset partially by increases in employee compensation costs and project-related spending.

The increases in sales, general and administrative expense for the three and nine months ended September 30, 2024, compared to the same periods in 2023, were primarily due to increases in bad debt expense and stock-based compensation of $0.3 million and $1.1 million for the three and nine months ended September 30, 2024, respectively.

We record income tax expense for taxes in our foreign jurisdictions including Austria, Finland, Italy, and South Korea. While our tax expense is largely dependent on the geographic mix of earnings related to our foreign operations, 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 United States and China, we continue to maintain a full valuation allowance in these jurisdictions as of September 30, 2024.
The increase in income tax expense for the nine months ended September 30, 2024 compared to the same period in 2023 is primarily due to a benefit for expiring statutes of limitations on unrecognized tax positions in the second quarter of 2023 and accrued interest on unrecognized tax positions. The increase in income tax expense for the three months ended September 30, 2024 compared to the same period in 2023 was mainly driven by an increase in income in foreign jurisdictions.
Liquidity and Capital Resources
We had cash and cash equivalents and restricted cash of $41.7 million and $53.5 million as of September 30, 2024 and December 31, 2023, respectively. In addition, we had marketable securities of $65.2 million and $59.7 million at September 30, 2024 and December 31, 2023, respectively. Our total balance of cash, cash equivalents, restricted cash and marketable securities decreased by $6.2 million from December 31, 2023 to September 30, 2024.
For the nine months ended September 30, 2024, our principal source of liquidity was cash collected from customers. 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. 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.
The following table summarizes our cash flows for the periods presented (in thousands):

| Nine Months Ended September 30,

Net cash provided by operating activities | $ | 1,528 |  |  | $ | 9,687 |  |  |

Net decrease in cash, cash equivalents and restricted cash | $ | (11,752) |  |  | $ | (5,736) |  |  |

Net Cash Provided by Operating Activities
During the nine months ended September 30, 2024, net cash provided by operating activities was $1.5 million, which was the result of a $35.8 million net loss, offset by a decrease in net working capital of $2.7 million and non-cash expenses totaling $34.7 million related primarily to depreciation, amortization, and stock-based compensation. The decrease in net working capital in the nine months ended September 30, 2024 was driven by a $3.3 million decrease in inventory, a $1.0 million decrease in prepaid expenses and other current assets, a $4.6 million increase in accounts payable and a $2.5 million increase in accrued and other long-term liabilities. These increases were offset by a $2.1 million increase in accounts receivable, a $3.4 million increase in other assets, net, a $1.9 million decrease in deferred revenues and a $1.5 million decrease in lease liabilities.
Net Cash Used in Investing Activities
During the nine months ended September 30, 2024, net cash used in investing activities was $10.9 million, which was driven by the net purchase of marketable securities of $5.6 million and capital expenditures of $5.3 million.
Net Cash Used in Financing Activities
During the nine months ended September 30, 2024, net cash used in financing activities was $2.4 million, which consisted of taxes paid on the net settlement of stock awards of $3.9 million, partially offset by proceeds from stock option exercises and employee stock plan purchases of $1.6 million.
Credit Facilities
24

Table of Contents
We have a $40.0 million revolving line of credit, or LOC, with Banc of California dated September 24, 2018, which is secured by our assets.
On September 27, 2024, we amended the LOC to extend the maturity date to September 24, 2027, updated financial covenants, and amend the unused line fee and interest rate applicable to revolving loans.
The LOC agreement contains restrictive and financial covenants and bears an unused credit fee of 0.25% 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, 2024 and we were in compliance with all covenants.
Contractual Obligations
There have been no material changes to our contractual obligations as previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023.
Inflation
We do not believe that inflation had a material effect on our business, financial condition or results of operations during the three and nine months ended September 30, 2024, If our costs become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. 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, 2023. Our exposure to market risk has not changed materially since December 31, 2023.
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
There were no changes in our internal control over financial reporting that occurred during the three months ended September 30, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
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.
