nLIGHT, Inc. (LASR)

nLIGHT designs, makes and sells high-power lasers: semiconductor lasers, fiber lasers, fiber amplifiers and beam combination and control systems, which customers build into their own laser systems or manufacturing tools. The core part is a compound semiconductor laser chip made from a gallium arsenide wafer, and the company says its patented multiplexed single-chip architecture combines several of those chips in one package. Its fiber lasers amplify that light in a proprietary fiber doped with a rare-earth element, and they are programmable: the size and shape of the beam and the timing of its pulses are set in software, so, as the filing puts it, one programmable laser can take the place of several less flexible ones. The company reports in two segments, Laser Products and Advanced Development, and sells into three end markets, Aerospace and Defense, Microfabrication and Industrial. 161718192021

How it operates

nLIGHT designs, makes and sells high-power lasers: semiconductor lasers, fiber lasers, fiber amplifiers and beam combination and control systems, which customers build into their own laser systems or manufacturing tools. The core part is a compound semiconductor laser chip made from a gallium arsenide wafer, and the company says its patented multiplexed single-chip architecture combines several of those chips in one package. Its fiber lasers amplify that light in a proprietary fiber doped with a rare-earth element, and they are programmable: the size and shape of the beam and the timing of its pulses are set in software, so, as the filing puts it, one programmable laser can take the place of several less flexible ones. The company reports in two segments, Laser Products and Advanced Development, and sells into three end markets, Aerospace and Defense, Microfabrication and Industrial. 161718192021

Alongside the products there is paid research. The Advanced Development segment researches, designs and prototypes next-generation laser technology in directed energy and laser sensing, centered, as the filing puts it, on providing governmental agencies with next-generation laser technologies and solutions, including custom high-power fiber lasers and beam combining. Most of those development contracts have historically been cost plus fixed fee, meaning the customer covers the costs and pays an agreed fee on top, with some fixed price work where what is earned moves with what the job ends up costing. All of that development revenue is counted in the Aerospace and Defense end market. 22232425

The company says it sells to and supports over 300 customers worldwide, but a few of them carry the revenue: the top ten were approximately 75% of revenues in 2025, 72% in 2024 and 66% in 2023. It names BAE Systems, KORD Technologies, Mazak, Northrop Grumman, QinetiQ Limited, Raytheon Technologies and the U.S. Government among its top customers. The U.S. Government on its own, counted without resellers that serve only the government, was 36% of revenues in 2025, against 19% in 2024 and 18% in 2023. In Aerospace and Defense it sells direct to end customers, the government, prime contractors and defense subcontractors, through its own teams in the United States; in Industrial and Microfabrication it sells through a direct sales force in the United States, China, South Korea and European countries, and through independent representatives and distributors elsewhere. 26272829

Counted by where products and services are delivered, North America was 185.6 million dollars, 71.0% of 2025 revenue, Asia Pacific 38.4 million, 14.7%, and EMEA, meaning Europe, the Middle East and Africa, 37.3 million, 14.3%. The making is mostly done in house: the company manufactures, packages and tests the critical parts, including the semiconductor laser chips and the optical fiber, at plants in Camas and Vancouver, Washington, Hillsboro, Oregon, Longmont, Colorado, and Lohja, Finland. It says vertical integration lets it control and protect its processes, and that it has invested in highly automated semiconductor packaging lines at Camas, which it believes is critical to serve the directed energy and laser sensing defense markets. A contract manufacturer in Thailand packages some semiconductor lasers for commercial use, and certain raw materials, among them semiconductor wafer substrates, fiber laser chip packages and optics, come from single or limited-source suppliers. 30313233343536

The specifics

What nLIGHT protects, it protects without leaning on any one patent. It uses patents, trade secrets and trademarks together with contracts, and says that although its intellectual property rights have significant value, it does not believe maintaining or growing the business is materially dependent on any single patent; in a field moving this fast, it adds, patents may matter less than technical expertise, new products, trade secrets, market penetration, customer relationships and service. The edge it claims for itself is vertical integration: controlling the full production process, it says, lets design cycles run faster. 373839

It names its competitors plainly: IPG Photonics, Coherent, BWT Ltd., Raycus Fiber Laser Technologies and Trumpf GmbH + Co. KG in lasers; prime defense contractors and subcontractors in Aerospace and Defense; and, in Industrial, widely used non-laser methods such as plasma cutting, water-jet cutting and resistance welding. It adds that some of its competitors are larger, with substantially greater financial, research, sales and marketing resources, and that certain of its own customers have internal laser technologies, which may add competitive pressure. 404142

Selling lasers into defense puts the company inside export control. It says it must export in compliance with U.S. export controls and may not always obtain the licenses it needs, and that denials or limits could harm its international and domestic revenues. Trade policy shows up too: the filing notes the new series of tariffs the U.S. government imposed on imported goods during 2025 and the retaliation that followed, and says those developments did not have a material impact on its 2025 results. Government work also sits outside the usual backlog arithmetic, because these contracts are typically only partially funded at any point in their term: the unfunded value of the company's government contracts, 184.4 million dollars at the end of 2025, is excluded from the backlog it reports. 4344454647

The company was incorporated as nLight Corporation in Washington in June 2000, reincorporated in Delaware as nLight Photonics Corporation in August 2000, and took the name nLIGHT, Inc. in January 2016. Its accounts consolidate wholly owned subsidiaries, among them nLIGHT Oy in Finland, nLIGHT Korea Inc., nLIGHT Laser Technology (Shanghai) Co. Ltd, nLIGHT Cayman Ltd. and nLIGHT DEFENSE Systems Inc., the one Camille Nichols ran for part of a year. The recent record is one of pulling back where the work is not: restructuring in the fourth quarters of 2023 and 2024 cut headcount mainly in China and ended all manufacturing there in the fourth quarter of 2024, and plans in the third and fourth quarters of 2025 cut headcount in China, Austria, Germany and Finland and wrote down in-process capital equipment for production capacity that had not been placed into service. After the year closed, in February 2026, the company issued and sold 4.6 million shares in an underwritten public offering; net proceeds after the underwriting discount were 192.2 million dollars. 484912505152

What drives growth, line by line

Aerospace and Defense. The big line, and the one that moved: 175.3 million dollars, 67.1% of 2025 revenue, up 60.0% from 109.5 million the year before. The filing credits increased unit sales of directed energy laser products and progress on existing development contracts, and all of the Advanced Development segment's contract research is counted here. The U.S. Government's own share of revenues rose to 36% from 19%. Why this market exists, in the company's words: against conventional weapons, directed energy weapons built on high-power fiber lasers offer ultra-precise targeting, low cost per shot and a nearly unlimited magazine, and the company says it has announced several Department of War sponsored programs. 305325275455

Microfabrication. 47.2 million dollars, 18.1% of revenue, up 8.8%. The filing puts the increase down to more semiconductor lasers sold in EMEA and Asia Pacific, partly offset by fewer sold in North America. Microfabrication is the making of three-dimensional microscale structures by ablating, annealing, etching, drilling or precision marking, the work behind small features in electronics, medical and semiconductor products. 305657

Industrial. The line that fell: 38.8 million dollars, 14.9% of revenue, down 14.8%. The filing blames fewer industrial fiber lasers sold for cutting and welding, on lower customer demand and deteriorating market conditions across all regions. In this market, the company says, programmable fiber lasers keep displacing CO2 lasers and other non-laser techniques in sheet metal cutting on speed, quality and cost; the strain showed in the accounts as inventory charges on Industrial products in the fourth quarter of 2024. 30585960

The two reportable segments cut the same revenue a different way. Laser Products, the product business, was 68.6% of revenue against 68.8% the year before, and Advanced Development, the contract research, was 31.4% against 31.2%, growing 32.6%. The filing says Laser Products rose on the Aerospace and Defense and Microfabrication markets, partly offset by Industrial, and that Advanced Development rose on progress on existing research and development contracts. 616263

Where it went: North America 185.6 million dollars, 71.0% of revenue, up 39.8%; EMEA 37.3 million, 14.3%, up 35.1%; Asia Pacific all but flat at 38.4 million, 14.7%, up 0.7%. The filing says North America rose on Aerospace and Defense, partly offset by Microfabrication and Industrial, and that Asia Pacific and EMEA rose on Aerospace and Defense and Microfabrication, partly offset by Industrial. The split counts the location products and services are delivered to. 306431

Set against the record, 2025 was a turn. Revenue had fallen three years running, from 270.1 million dollars in 2021 to 198.5 million in 2024, before 261.3 million in 2025. Gross margin was 29.8% against 16.6%, which the proxy statement puts down to higher volumes, a more favorable customer and product mix and better cost absorption; the annual report adds duty reclaim and manufacturing yields, and notes that 2024 had carried inventory charges on Industrial products. The net loss narrowed to 23.5 million dollars from 60.8 million. 6566676860

What the company itself says about what comes next: backlog of 161.6 million dollars at the end of 2025, against 167.0 million a year earlier, all of it expected to be filled within the next 24 months, and, apart from that, 184.4 million dollars of unfunded government contract value the backlog does not count. It says it intends to continue its commitment to research and development and to introduce new products, and that its existing sources of liquidity will be sufficient to meet its working capital and capital expenditure needs for at least the next 12 months. 69477071

What the desk infers Inferred

1. Inferred

   nLIGHT now earns most of its money from a small number of United States government directed energy and laser sensing programs, so what it takes in follows government program funding more than the industrial laser cycle the company grew up on.

   Because

   • Aerospace and Defense was 175.3 million dollars, 67.1% of revenue, and grew 60.0%, while Industrial fell 14.8%. 30
   • The U.S. Government on its own, counted without resellers that serve only the government, was 36% of revenues in 2025 against 19% in 2024 and 18% in 2023, and the top ten customers together were approximately 75%. 2726
   • All of the Advanced Development segment, the paid research business, is counted inside the Aerospace and Defense market. 25
   • 184.4 million dollars of government contract value sat unfunded at the end of 2025 and is excluded from backlog, because such contracts are typically only partially funded at any point in their term. 4746
   Confidence 85 of 100Wrong if A year in which the Aerospace and Defense market falls below half of revenue, or in which the U.S. Government's share of revenues returns to its 2023 level while total revenue keeps rising.
2. Inferred

   The growth of the last year came mostly from work contracted directly with the government rather than from the prime contractors that headed the customer list a year earlier.

   Because

   • The U.S. Government's share of revenues rose to 36% in 2025 from 19% in 2024, while KORD Technologies, at 12% of revenues in 2024, and Raytheon Technologies, at 10%, both fell under the 10% line that requires naming. 27
   • Total revenue grew 31.6% over the same year, so the government's share nearly doubling came on a bigger base, while a prime contractor whose own dollars merely held their place would slip under the naming line. 72
   • In Aerospace and Defense the company sells directly to end customers, the U.S. Government, prime contractors and defense subcontractors alike, so both routes are open to it. 28
   • The segment that grew fastest, Advanced Development at 32.6%, is contract research whose revenue is counted in the Aerospace and Defense market. 6225
   Confidence 60 of 100Wrong if A disclosure showing that sales to KORD Technologies and Raytheon Technologies grew in 2025 by more than the company's total revenue, which would mean prime contractors carried the growth.
3. Inferred

   The Industrial business is being shrunk rather than defended, while the money and the floor space go to defense work in the United States.

   Because

   • Industrial revenue fell 14.8% to 38.8 million dollars and is down to 14.9% of the total. 30
   • The restructuring of the fourth quarter of 2024 ended all manufacturing in China, and the plans of the third and fourth quarters of 2025 cut headcount in China, Austria, Germany and Finland and wrote down in-process capital equipment for production capacity that had not been placed into service, or redundant equipment the company intends to sell. 50
   • Gross margin in 2024 was held down by inventory charges on products for the Industrial market. 60
   • At the same time the company says it has invested in highly automated semiconductor packaging lines at its Camas, Washington plant, which it believes is critical to serve the directed energy and laser sensing defense markets. 34
   Confidence 70 of 100Wrong if A filing that shows industrial revenue growing again alongside new spending on industrial laser capacity, or a statement that the company is adding capacity for cutting and welding lasers.
