nLIGHT (LASR) Q3 2026 earnings review
nLIGHT plans record sales, but parts shortages last into 2027
nLIGHT, which makes high-power lasers for weapons and factories, earned more per laser while missing parts held back shipments. Sales rose 11% from a year ago, above the top of its own range. Its laser products earned a record 47% gross margin, but operating cash turned negative as nLIGHT stockpiled parts.
| Revenue | $73.8M +10.5% from a year ago |
|---|---|
| Product gross margin | 47.4% 41.0% a year ago |
| Cash from operations | -$13.1M +$5.2M a year ago |
| Fourth-quarter sales outlook | New: $84–90M middle of the range: 7% growth |
⚖️ Verdict: 🟢 Bullish
The story got better because the fourth-quarter plan points to record sales even without the orders the parts shortage delayed. By our math, its middle sits 7% above last year. The bad news: finance chief Joe Corso expects most delayed orders only in the first half of next year. And beating its own range says the old plan was cautious, not that the shortage ended.
The question now is whether defense sales keep growing as HELSI-2, nLIGHT's megawatt laser program, winds down. Either JLWS, a new contract to build whole laser weapons, fills the gap, or defense revenue stops rising between programs. Fourth-quarter defense product sales and the year-end order book will tell.
🐂 Bull Case
Laser Products Earned a Record 47% Margin
Gross margin shows how much of each sales dollar nLIGHT keeps after paying to make its lasers. In the third quarter, making its products cost 52.6% of product sales, against 59.0% a year ago.
The margin rose even though product sales fell 19% from the second quarter. Finance chief Joe Corso credited a better mix, busier factories, lower reserves and smaller tariff bills. He also said "we had a few things that went right" that he does not plan on repeating.
- Product gross margin: 47.4%, against 41.0% a year ago
- Sales, general and administrative costs: 18.5% of revenue, down 3.6 percentage points
- Operating margin excluding restructuring: -2.4%, against -8.3% a year ago
Corso said "we expect our product gross margins to remain comfortably above 40%". That base sits above most quarters of 2025, so extra volume from the delayed orders should reach profit quickly.
What to watch: product gross margin in the fourth-quarter results, due early next year. A reading at or above the middle of the new range would show the factory gains holding as shipments recover.
Weapon Development Work Grew 34% as JLWS Started
Advanced Development is nLIGHT's paid research and prototype work for the US military. Its newest job is the Joint Laser Weapon System (JLWS), a $627 million award to build "complete containerized high-energy laser weapon systems", chief executive Scott Keeney said.
Development revenue climbed 34% from a year ago. Finance chief Joe Corso credited HELSI-2, a program to build a one-megawatt laser, and "the initial ramp of our JLWS contract". JLWS matters because HELSI-2 is entering final assembly, and Keeney said the Department of War aims to field JLWS in 2028.
What to watch: development revenue in the fourth-quarter results. The company's own plan has it slipping from the third quarter, so a figure above that plan would show JLWS growing fast enough to replace HELSI-2.
Fourth-Quarter Plan Points to Record Sales
nLIGHT has beaten the middle of its own quarterly sales range in every recent quarter. The third quarter landed 8.5% above it, close to the usual beat of about 8%.
For the fourth quarter, finance chief Joe Corso set a range whose middle is $87 million, above the record $82.6 million of the second quarter. The range leaves out orders that missing parts pushed into next year, so it rests on current demand alone.
This matters because quarterly sales have hovered near $80 million for a year. Still, a beat on an old plan shows only that the plan was cautious.
What to watch: fourth-quarter revenue against the bottom of the new range. Falling short would mean the shortage reached orders the laser maker had counted on shipping this year.
Positives this quarter didn't test
Four growth lines that nLIGHT keeps pointing to got comments on the call but no sales figures in the third-quarter results.
- Missile and munition parts: chief executive Scott Keeney said stockpile rebuilding keeps demand strong; an order or sales figure would move this.
- Laser sensing for missiles and intelligence: finance chief Joe Corso said newer programs are ramping; a sales split would move this.
- Space: Keeney named it a growth area again; a first revenue number would move this.
- Metal 3D printing lasers: Corso expects growth in the fourth quarter; a growth rate for this line would move it.
🐻 Bear Case
Missing Parts Delay $15 Million Into 2027
Many optical parts in nLIGHT's lasers come from China, where customs officials have held shipments since new export rules took effect in June. Chief executive Scott Keeney said "the optical supply chain remains heavily concentrated in China, and qualifying a new source takes time".
Three months ago, nLIGHT left about $17 million of product sales out of its third-quarter plan and expected to deliver them later. Of that sum, finance chief Joe Corso said "we were able to ship a couple million dollars of it". The fourth-quarter plan now "excludes approximately $15 million of product revenue", the company said.
Keeney said the delayed shipments will go out "in coming quarters", but the delayed sum barely shrank in three months. Corso said nLIGHT does "not expect to ship most of this pent-up demand until the first half of 2027". The shortage hits mainly Advanced Manufacturing, the factory-laser business, which grew less than 1% from a year ago.
What to watch: whether the $15 million ships in the first half of 2027, as Corso expects. If each new plan keeps carrying a similar delayed sum, the shortage caps sales rather than shifting them.
Defense Sales Fell 8% From Last Quarter
Defense & Space, nLIGHT's military and space business, made up 71% of revenue. These sales rose 15% from a year ago but fell 8% from the second quarter.
Finance chief Joe Corso blamed HELSI-2, the one-megawatt laser program, where nLIGHT is "largely finished" shipping amplifiers. By our math, defense product sales dropped 21.5% from the second quarter. He expects them to rise again in the fourth quarter.
This matters because HELSI-2 nears its end before JLWS, the new weapon contract, reaches full size. Some programs also run on a temporary budget, "funded under a continuing resolution that expires on December 11, 2026", the company wrote.
What to watch: defense product sales in the fourth-quarter results. Another drop from the third quarter would mean the gap between HELSI-2 and JLWS has reached revenue.
Stockpiling Parts Turned Operating Cash Negative
nLIGHT bought parts ahead of need so the shortage would not idle its factories. Finance chief Joe Corso said "we've leaned in and we've secured some supply" to meet growth plans, and that choice used cash.
- Operating cash flow: -$13.1 million, against +$5.2 million a year ago
- Inventory: $59.8 million, up 24% from last quarter
- Days to turn stock and customer bills into cash: 112, against 91 last quarter
The company's slides point to "Positive cash from operations on a year-to-date basis". That holds, but the third quarter alone undid more than a third of the first half's inflow. Its $314.5 million of cash and investments covers the outflow, so the issue is conversion, not survival.
What to watch: operating cash flow in the fourth quarter. A return to inflow would show the stockpile turning into shipped lasers.
Risks this quarter didn't answer
Five standing risks got little or no new evidence in the third-quarter results, so they carry over into next quarter unchanged.
- Funded order book: no figure since the end of 2025; the year-end number with fourth-quarter results will show whether JLWS refilled it.
- Development margin: 6.5%, still under the 8% plan; the JLWS contract type, cost-plus or fixed-price, would settle it.
- Stock pay: $9.9 million, 13% of revenue, which keeps the reported result a loss; a falling share of revenue would ease it.
- Customer concentration: the US government bought 39% of quarterly sales, against 35% a year ago; a broader customer list would ease it.
- One-megawatt HELSI-2 laser: no delivery date in the results; a completed delivery would ease the execution risk.
👓 Other Themes
nLIGHT Closed Its China Operations
nLIGHT spent $7.5 million on restructuring to shut its business in China, mostly on severance and write-downs. Chief executive Scott Keeney said "we completed our efforts to cease all operations in the country", while the quarterly filing says "nearly all". After quitting cutting and welding lasers, the group also merged two factory markets into one called Advanced Manufacturing.
💲 Other KPIs
Customer prepayments held close to last quarter's level after a steep climb in the first half. Deferred revenue, cash customers pay before nLIGHT delivers, stood at about four times its level a year ago, by our math. The sum is small next to quarterly sales, so it barely offsets the cash tied up in parts.
The share count kept rising, but more slowly. Diluted shares, which include stock awards, rose 14% from a year ago, against about 22% in the first half. The February stock sale and employee awards drove the increase, so each share claims a smaller slice of any profit.
Spending on equipment and buildings climbed to 6% of revenue from about 4% a year ago, by our math. Finance chief Joe Corso tied it to adding factory capacity for expected demand. The outlay stays small next to the laser maker's cash and investments, so it does not strain the balance sheet.
🔮 Guidance
New. The plan puts fourth-quarter sales about 7% above a year ago, by our math. That is also an 18% jump from the third quarter. At the middle, nLIGHT would set a quarterly record. The range leaves out the orders delayed into 2027, so faster parts deliveries would add to it.
New. By our math, product sales would climb about 31% from the third quarter. They would sit 14% above a year ago. Corso expects both defense and factory lasers to grow. The figure assumes the company ships to current demand but does not catch up on delayed orders.
New. Research and prototype revenue would slip about 7% from the third quarter. By our math it would also sit 8% below a strong year-ago quarter. So JLWS work has not yet grown enough to replace HELSI-2 as that program moves into final assembly.
New. The middle of the range, 33%, matches the third quarter. A larger share of product sales helps the blend, but the outlook assumes product margins give back part of their record.
New. The middle, 43%, sits below the third-quarter record because Corso did not count on its one-time gains repeating. By our math, nLIGHT beat the middle of this range by about 3 points on average in the three quarters before the latest one.
New. The research business keeps the 8% target it has used all year. On reported figures it fell short in each quarter of 2026, reaching 6.5% in the third quarter. Excluding stock pay, it did hit the target this time.
New. Profit before interest, tax, depreciation, stock pay and one-offs would rise about 36% from the third quarter, by our math. That puts the margin near 17%, matching the first-quarter high. Corso expects extra volume to pass through with little added cost.
Unchanged. Operating costs excluding stock pay and one-offs stay in the band Corso set for the second half. The third quarter came in at $17.4 million, near the bottom, and he expects a modest rise.
❓ Key Questions
How large is the funded order book after JLWS?
nLIGHT has given no funded order figure since the end of 2025, when it stood at $162 million. The JLWS award came after that date, so the year-end number will show how much future work customers have already paid for.
Is JLWS cost-plus or fixed-price work?
Development margin stayed under the 8% plan on reported figures all year. The contract type decides whether JLWS lifts or dilutes that margin as it grows into nLIGHT's largest program.
How much defense output depends on Chinese optical parts?
Corso said the shortage hits mostly factory lasers today. Readers need the share of defense products that use Chinese optics, and when second suppliers finish qualification, to judge whether the problem can spread.
When will nLIGHT deliver the one-megawatt HELSI-2 laser?
HELSI-2 has moved to final assembly, and its amplifier shipments are largely over. A delivery date, and the revenue left on the program, would show how deep the gap before JLWS ramps could be.
How much cash will the parts stockpile absorb next quarter?
Operating cash flow swung to an outflow as inventory jumped. A target for inventory and for unbilled contract work would show when the cash comes back.
