nLIGHT (NASDAQ: LASR) surges to Q1 2026 profit on 55% revenue growth and cash raise

Rhea-AI Filing Summary

nLIGHT, Inc. reported a strong turnaround for the quarter ended March 31, 2026. Revenue rose to $80.2 million from $51.7 million a year earlier, driven mainly by higher product and development sales to the Aerospace and Defense market, with additional growth in Microfabrication and Industrial demand.

The company generated net income of $0.6 million, compared with a net loss of $8.1 million in the prior-year period, as gross margin improved to 33.1% from 26.7% on better product mix and higher factory utilization. Operating expenses increased, largely due to higher stock‑based compensation and headcount, and included $0.3 million of restructuring costs tied to excess manufacturing space.

Liquidity strengthened significantly after a February 2026 public offering of 4.6 million shares that delivered $191.3 million in net proceeds. Cash, cash equivalents, restricted cash and marketable securities climbed to $332.9 million, while $20.0 million remained drawn on a $40.0 million revolving credit line. Management believes existing liquidity will cover working capital and capital spending needs for at least the next 12 months.

Positive

• Sharp top-line growth and profitability turnaround: Revenue increased 55% year over year to $80.2 million, led by Aerospace and Defense demand, and results swung from an $8.1 million net loss to $0.6 million of net income as gross margin expanded to 33.1%.

Negative

• Dilution and higher operating costs: A February 2026 follow-on offering added 4.6 million shares, while sales, general and administrative expense rose 25% year over year, largely from higher stock-based compensation, which can weigh on per‑share metrics.

Insights

Equity research analyst

nLIGHT posts strong revenue growth, returns to profit, and significantly boosts liquidity.

nLIGHT delivered quarterly revenue of $80.2 million, up 55% year over year, with most of the increase from Aerospace and Defense, supported by higher unit sales of directed energy laser products and progress on development contracts. Both Laser Products and Advanced Development segments contributed to growth.

Gross margin improved to 33.1% from 26.7%, as product mix and higher production volumes helped absorb fixed manufacturing costs. Development margins compressed because of greater use of cost‑plus fixed fee contracts, which typically earn lower margins than firm fixed price work.

In February 2026, the company raised net proceeds of $191.3 million from a follow‑on equity offering, pushing total cash, cash equivalents, restricted cash and marketable securities to $332.9 million at quarter‑end. While this adds dilution, it also reduces financing risk and sits alongside a $40.0 million revolving credit facility with $20.0 million drawn.

Key Terms

cost plus fixed fee, firm fixed price, performance obligations, Aerospace and Defense, +2 more

6 terms

cost plus fixed fee financial

"Most of our Development contracts have historically been structured as cost plus fixed fee due to the technical complexity"

firm fixed price financial

"we also perform work under fixed price contracts where gross margin can change from period to period"

A firm fixed price is a contract where the buyer and seller agree on a single, unchanging price for goods or services that does not shift if the seller’s costs go up or down. Investors care because it makes revenue and profit more predictable for the seller while transferring cost risk to the seller; like agreeing to buy a meal at a set price even if ingredient costs later rise, it can boost short-term stability but increase exposure to cost overruns.

performance obligations financial

"As of March 31, 2026, we had $1.4 million of performance obligations relating to firm fixed price contracts"

Performance obligations are the specific promises a company makes to deliver goods or services to a customer under a contract, treated as separate deliverables when a customer can benefit from them on their own. Investors care because these promises determine when and how much revenue a company records — like breaking a bundled purchase into separate billable parts — which affects reported earnings, growth trends and the clarity of future cash flows.

Aerospace and Defense financial

"We sell our products into three primary end markets: Aerospace and Defense, Industrial, and Microfabrication."

Aerospace and defense encompass industries involved in designing, manufacturing, and supporting aircraft, spacecraft, military equipment, and security systems. These sectors are crucial for national security, technological innovation, and transportation. For investors, they represent areas with significant government contracts and long-term growth potential driven by advancements in technology and defense needs.

Rule 10b5-1 trading arrangement regulatory

"no director and officer ... adopted a “Rule 10b5-1 trading arrangement” as defined in Regulation S-K Item 408."

revolving line of credit financial

"We have a $40.0 million revolving line of credit (LOC) with Banc of California dated September 24, 2018"

A revolving line of credit is a flexible borrowing arrangement that allows a person or business to access funds up to a set limit whenever needed, much like a prepaid card. As money is repaid, it becomes available to borrow again, making it a convenient way to manage cash flow or cover ongoing expenses. Investors pay attention to it because it reflects a company’s ability to access quick funds and manage financial flexibility.

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, 2025.

Critical Accounting Policies

Our critical accounting policies have not materially changed during the three months ended March 31, 2026, from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025.

New Accounting Pronouncements

ASU 2024-03

In November 2024, the FASB issued ASU 2024-03 related to the disaggregation of certain income statement expenses. The amendments in this update require public entities to disclose incremental information related to purchases of inventory, team member compensation and depreciation, which will provide investors the ability to better understand entity expenses and make their own judgments about entity performance. The amendments in this update are effective for fiscal years beginning after December 15, 2026. We plan to adopt this pronouncement and make the necessary updates to our disclosures for the year ending December 31, 2027, and, aside from these disclosure changes, we do not expect the amendments to have a material effect on our financial position, results of operations or cash flows.

ASU 2025-10

In December 2025, the FASB issued ASU 2025‑10 related to government grants received by business entities. The amendments in this update establish recognition, measurement, presentation, and disclosure guidance for government grants and require such grants to be recognized only when it is probable that the entity will comply with the related conditions and that the grant will be received. The amendments in this update are effective for annual periods beginning after December 15, 2028. We are evaluating the amendments and expect to adopt the guidance when it becomes effective. We do not expect the amendments to have a material effect on our financial position, results of operations, or cash flows.

ASU 2025-11

In December 2025, the FASB issued ASU 2025-11 related to interim reporting. The amendments in this update clarifies and streamlines interim reporting disclosure requirements. The amendments are effective for interim reporting periods within fiscal years beginning after December 15, 2027 for public business entities. We are evaluating the amendments and expect to adopt the guidance when it becomes effective. We do not expect the adoption of ASU 2025‑11 to have a material impact 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

6

Table of Contents

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 information related to those performance obligations under ASC 606-10-50-14b. As of March 31, 2026, we had

$1.4 million of performance obligations relating to firm fixed price contracts that did not qualify for the aforementioned disclosure exemptions. We expect to recognize 96% of these performance obligations by the end of 2026 and the remainder by the end of 2027.

We have elected, per ASC 606-10-25-18B (shipping and handling practical expedient), to recognize shipping and handling services performed after control transfer as fulfillment costs.

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 amplifiers, 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):

Sales by Timing of Revenue

			Three Months Ended March 31,

Point in time			$	57,008					$	35,680
Over time			23,173						15,988
			$	80,181					$	51,668

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

			Balance Sheet Classification						As of
									March 31, 2026						December 31, 2025
Contract assets			Prepaid expenses and other current assets						$	17,539					$	6,188
Contract liabilities			Deferred revenues and other long-term liabilities						7,502						5,566

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 months ended March 31, 2026, we recognized revenue of $1.7 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 March 31,
			2026						2025
U.S. Government*			36%						35%

*Excludes sales to customers who sell our products and services exclusively to the U.S. Government

Financial instruments that potentially expose us to concentrations of credit risk consist principally of receivables from customers. As of March 31, 2026, two customers accounted for a total of 32% of our net customer receivables. No other customers accounted for 10% or more of net customer receivables at this date. As of December 31, 2025, no customer accounted for 10% or more of our net customer receivables.

Note 4 - 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):

			March 31, 2026
			Level 1			Level 2			Level 3			Total
Cash Equivalents:
Money market securities			$	123,973		$	—		$	—		$	123,973

Total			$	59,927		$	—		$	—		$	59,927

Cash Equivalents

The fair value of cash equivalents is determined based on quoted market prices for similar or identical securities.

Marketable Securities

Marketable securities consist primarily of highly liquid investments with original maturities of greater than 90 days when purchased. We classify our marketable securities as available-for-sale, as they represent investments that are available to be sold for current operations, and value them utilizing a market approach that uses observable inputs without applying significant judgment.

Note 5 - 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):

			As of
			March 31, 2026						December 31, 2025
Raw materials			$	22,842					$	23,064
Work in process and semi-finished goods			17,952						19,408

Note 8 - Line of Credit

We have a $40.0 million revolving line of credit (LOC) with Banc of California dated September 24, 2018, which is secured by our assets and matures on September 24, 2027. The LOC agreement contains restrictive and financial covenants and bears an unused credit fee of 0.25% on an annualized basis. The interest rate of 5.75% on the LOC at March 31, 2026 is based on the Prime Rate, minus a margin based on our liquidity levels.

As of March 31, 2026, $20.0 million was outstanding on the LOC and we were in compliance with all covenants.

Interest expense on the LOC was $0.3 million for the three months ended March 31, 2026.The remaining $20.0 million unused portion of the LOC is available for borrowing

Other accrued expenses			1,256						1,060
			$	16,929					$	19,052

Note 10 - Product Warranties

We provide warranties on certain products and record a liability for the estimated future costs associated with warranty claims at the time revenue is recognized. The warranty liability is based on historical experience, any specifically identified failures, and our estimate of future costs. The current portion of our product warranty liability is included in the accrued liabilities and the long-term portion is included in Other long-term liabilities in our Consolidated Balance Sheets.

Legal Matters

From time to time, we may be subject to various legal proceedings and claims in the ordinary course of business. As of March 31, 2026 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 0.4 to 9.2 years, and some leases include options to extend up to 10 years. Other leases for automobiles, manufacturing and office and computer equipment have remaining lease terms of 0.2 to 4.8 years. These leases are primarily operating leases; financing leases are not material. We did not include any renewal options in our lease terms for calculating the lease liabilities as we are not reasonably certain we will exercise the options at this time. The weighted-average remaining lease term for the lease obligations was 6 years as of March 31, 2026, and the weighted-average discount rate was 5.1%.

Note 15 - Segment Information

We operate in two reportable segments consisting of the Laser Products segment and the Advanced Development segment. We organize our business segments based on the nature of products and services offered.

14

Table of Contents

Laser Products

This segment includes the design, development, production and integration of high-power semiconductor lasers and fiber lasers and related components, modules and subsystems that are typically integrated into laser systems or manufacturing tools built by us or our customers for use in a range of commercial and defense applications. This segment also includes fiber amplifiers and beam combination and control systems for use in high-energy laser (HEL) systems in directed energy applications, and laser sensing products used in a wide range of defense applications.

Advanced Development

This segment focuses on technology integration as well as research, design, and prototyping of next-generation laser technologies for the defense industry, including the development of custom high-power fiber lasers and advanced beam combining technologies.

Segment Financial Data

Our Chief Executive Officer serves as the chief operating decision maker (CODM) and is responsible for reviewing segment performance and making decisions regarding resource allocation. Our CODM uses revenue, gross profit, and gross margin to evaluate each segment's performance by comparing the metrics to historical results and previously forecasted financial information. Segment gross profit is the primary measure of segment profit or loss, and cost of revenue is the only significant expense category, and therefore we have no other segment items. In addition, our CODM does not evaluate operating segments using asset or liability information. The following table summarizes the operating results by reportable segment for the periods presented (dollars in thousands):

			Three Months Ended March 31,
			2026																		2025
			Laser Products						Advanced Development						Total						Laser Products						Advanced Development						Total

Interest expense															(300)																		(48)
Other income, net															155																		14
Income (loss) before income taxes															$	698																	$	(7,956)

Other cost of revenue consists of stock-based compensation expense, which is not used in evaluating the results of, or in the allocation of resources to, our reportable segments.

There have been no material changes to the geographic locations of our long-lived assets, net, based on the location of the assets, as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025.

Note 16 - Net Income (Loss) per Share

Basic income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the period.

Diluted income (loss) per share is computed by dividing net income by the weighted-average number of common shares outstanding during the period and potentially dilutive shares of common stock outstanding during the period. Potentially dilutive shares whose effect would have been anti-dilutive are excluded from the computation of diluted earnings per common share.

Overview

nLIGHT, Inc. is a leading provider of high‑power lasers for mission-critical directed energy, optical sensing, and advanced manufacturing applications. We design, develop, manufacture, integrate and sell a range of high-power semiconductor lasers and fiber lasers and related components, modules and subsystems that are typically integrated into laser systems or manufacturing tools built by us or our customers. We also make high energy pulsed fiber lasers, fiber amplifiers, and beam combination and control systems for use in high-energy laser systems for directed energy and laser sensing systems for use in a wide range of commercial and defense applications. Our long history of commercial technology development and vertical integration enables us to develop products that leverage the same underlying technology across a variety of applications and markets, thereby enabling us to leverage the development of shared technologies in unique combinations to offer innovative and reliable products to customers in each of our end markets. We sell our products into three primary end markets: Aerospace and Defense, Industrial, and Microfabrication.

We operate in two reportable segments consisting of the Laser Products segment and the Advanced Development segment.

Revenues increased to $80.2 million in the three months ended March 31, 2026 compared to $51.7 million in the same period in 2025 due primarily to an increase in both product and development revenue from the Aerospace and

Factors Affecting Our Performance

Demand for our Products and Solutions

Our revenue depends largely on market conditions, competitive pressure, and achievement of design wins. 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. In the Aerospace and Defense market, our business also 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 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.

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

Product gross profit, in absolute dollars and gross margin, may fluctuate from period to period based on 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. 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. Even though certain of our products are built offshore by contract manufacturers, capacity utilization affects gross margin because of the fixed cost associated with our U.S.-based manufacturing capabilities. Change in sales and production volumes impact absorption of fixed costs, manufacturing efficiencies and production costs.

Our 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 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.

Global Economic Conditions

A portion of our sales are generated from products manufactured outside the United States and we sell our products globally. Changing trade dynamics, including changes in tariffs and export regulations, could disrupt our supply chain, disrupt customer sales, and increase input costs. We continue to monitor macroeconomic trends, global inflationary pressures, and uncertainties related to international trade policy, including tariff actions and regulatory shifts. For instance, in February 2026, the U.S. Supreme Court issued a ruling invalidating certain tariffs previously imposed under the International Emergency Economic Powers Act (IEEPA). In March 2026, the U.S. Court of International Trade Court issued an additional ruling stating that importers that have paid tariffs under IEEPA are

due refunds. We are currently evaluating the impact of this decision on our business, as the ultimate timing and amount of any potential refunds is uncertain and subject to further legal and regulatory developments.

Changes in global economic conditions and tariffs on goods to and from the U.S. did not have a material impact on our financial results in the three months ended March 31, 2026. However, changes in global economic conditions and uncertainty related to tariffs could increase our operational complexity, and have a negative impact on revenue and profitability in the future.

Table of Contents

Our gross profit and gross margin were as follows for the periods presented (dollars in thousands):

			Three Months Ended March 31,
			2026																		2025
			Products						Development						Total						Products						Development						Total
Gross profit			$	25,392					$	1,121					$	26,513					$	11,954					$	1,845					$	13,799
Gross margin			43.6		%				5.1		%				33.1		%				33.5		%				11.5		%				26.7		%

The increase in products gross margin for the three months ended March 31, 2026 compared to the same period in 2025 was driven primarily by sales mix and the impact of increased production volumes on fixed manufacturing costs due to the overall increase in sales. The decrease in development gross margin for the three months ended March 31, 2026 compared to the same period in 2025 was primarily the result of an increase in revenue from cost-plus fixed fee (CPFF) contracts relative to firm fixed price (FFP) contracts. CPFF contracts generally have a lower average gross margin than FFP contracts.

Operating Expenses

Our operating expenses were as follows for the periods presented (dollars in thousands):

Research and Development

			Three Months Ended March 31,												Change
			2026						2025						$						%
Research and development			$	11,846					$	11,374					$	472					4.1		%

The increase in research and development expense for the three months ended March 31, 2026 compared to the same period in 2025 was driven by an increase in stock-based compensation of $0.5 million, an increase in employee compensation due to an increase in headcount, partially offset by a decrease in project-related expenses.

Table of Contents

Interest income is primarily earned from our marketable securities (U.S. treasuries), recognized using the effective yield method, and cash equivalents (money market securities).

Interest (expense)

			Three Months Ended March 31,												Change
			2026						2025						$						%
Interest expense			$	(300)					$	(48)					$	(252)					525.0%

The increase in interest (expense), for the three months ended March 31, 2026 compared to the same period in 2025 was driven primarily by an increase in interest expense on line of credit (LOC). Interest expense on the LOC for the three months ended March 31, 2025 was immaterial due to the timing of the draw.

Other Income, net

			Three Months Ended March 31,												Change
			2026						2025						$						%
Other income, net			$	155					$	14					$	141					1,007.1%

Other income, net is primarily attributable to changes in net realized and unrealized foreign exchange transactions resulting from currency rate fluctuations.

Income Tax Expense

			Three Months Ended March 31,												Change
			2026						2025						$						%
Income tax expense			$	53					$	137					$	(84)					(61.3)		%

We record income tax expense for taxes in our foreign jurisdictions including Finland, Italy, Austria, China 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, we continue to maintain a full valuation allowance on deferred tax assets in the United States, and a partial valuation allowance in China as of March 31, 2026. Our effective tax rate may vary from period to period based on changes in estimated taxable income or loss by jurisdiction, changes to the valuation allowance, changes to U.S. federal, state or foreign tax laws, future expansion into areas with varying country, state, and local income tax rates and deductibility of certain costs and expenses by jurisdiction.

The decrease in income tax expense for the three months ended March 31, 2026, compared to the same period in 2025 was driven by a decrease in income from our foreign operations. Our tax expense is dependent on the geographic mix of earnings and primarily related to our foreign operations.

Liquidity and Capital Resources

We had cash and cash equivalents and restricted cash of $298.5 million and $99.0 million as of March 31, 2026 and December 31, 2025, respectively. In addition, we had marketable securities of $34.4 million and $34.9 million at March 31, 2026 and December 31, 2025, respectively. Our total balance of cash, cash equivalents, restricted cash and marketable securities increased by $199.0 million from December 31, 2025 to March 31, 2026.

For the three months ended March 31, 2026, our principal sources of liquidity was from our public offering and 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

Net Cash Used in Investing Activities

During the three months ended March 31, 2026, net cash used in investing activities was $1.4 million, which was driven by net capital expenditures of $2.1 million, offset by the net proceeds from maturities and sales of marketable securities of $0.7 million.

Credit Facilities

We have a $40.0 million revolving LOC with Banc of California dated September 24, 2018, which is secured by our assets and matures on September 24, 2027. The LOC agreement contains restrictive and financial covenants, including a minimum total cash covenant, and bears an unused credit fee of 0.25% on an annualized basis. The interest rate of 5.75% on the LOC at March 31, 2026 is based on the Prime Rate, minus a margin based on our liquidity levels.

As of March 31, 2026, $20.0 million was outstanding on the LOC and we were in compliance with all covenants. The remaining $20.0 million unused portion of the LOC is available for borrowing.

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, 2025.

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

Table of Contents

Report on Form 10-K for the year ended December 31, 2025. Other than with respect to the variable interest rate on our LOC due to our draw of $20.0 million on our LOC with Banc of California, our exposure to market risk has not changed materially since December 31, 2025.

We are subject to interest rate risk in connection with the borrowings under our LOC. We have a $40.0 million revolving credit facility. As of March 31, 2026, we had $20.0 million outstanding under the LOC. Borrowings under the LOC bear interest at a per annum rate, depending on certain liquidity thresholds, ranging from the Prime Rate minus 1.0% to the Prime Rate. A 10% increase or decrease in interest rates would result in approximately a $0.1 million change in our obligations under the loan facility.

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 March 31, 2026 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.

What drove nLIGHT (LASR) revenue growth in Q1 2026?

How did nLIGHT’s gross margin change year over year in Q1 2026?

How much did nLIGHT (LASR) spend on research and development in Q1 2026?
