nLIGHT, Inc. (LASR) | The Buildout — AI Infrastructure
The Verdict
nLIGHT makes high-power semiconductor and fiber lasers that customers integrate into laser systems or manufacturing tools. Management calls directed energy its most strategic and highest-growth opportunity: laser weapons for the U.S. and allied governments, using coherent beam combining and atmospheric correction. It also supplies laser sensing for munitions and space, and commercial lasers for microfabrication and industrial/additive manufacturing. It is not an AI infrastructure supplier; no AI revenue is named or sized.

What We Like
- JLWS is a new multiyear Department of War award with a ceiling over $600M and $44M of initial funded work; management says it will more than replace HELSI-2 in 2027.
- Directed-energy budget backdrop: nearly $400M in each of FY2027 and FY2028 for prototypes and procurement, and approximately $1B annual total for directed-energy laser weapons.
- Q2 2026 was a record: total revenue $82.6M, +34% y/y; products revenue $59M, +45%; A&D revenue $57.3M, +41%.
- Balance sheet has $330.8M in cash, equivalents, restricted cash and investments; the company repaid the $20M revolver draw in Q2 and generated record $20.7M operating cash flow.
- Missile/kinetic sensing awards doubled from $25M to $50M for roughly the same period of performance, and A&D product revenue grew 72% y/y in Q2 2026.
What We’re Watching
- China dual-use optics constraints delayed approximately $17M of product revenue out of Q3 2026; management puts resolution between “quite quickly” and “months to quarters.”
- Q3 2026 guidance is $63M–$73M, with total gross margin 24%–30%, product gross margin 34%–40%, and adjusted EBITDA $1M–$7M, all tied to lower product volumes.
- Q4 backlog execution is called “a little bit of a question mark” by management even as demand and backlog are described as strong.
- Customer concentration is high: U.S. Government was 36% of FY2025 and Q1 2026 revenue; KORD Technologies 12% and Raytheon 10% of FY2025; two customers were 32% of net receivables at 2026-03-31.
The strategic thesis is strengthening: JLWS gives a multiyear defense program, directed-energy budgets are large, and the balance sheet is strong. The near-term thesis is weaker: the optics supply delay cuts Q3 guidance, margins are volume-sensitive, and Q4 execution is uncertain. The open question is whether the approximately $17M delayed revenue is recovered in Q4 and whether JLWS ramps in 2027 enough to more than replace HELSI-2.

we expect revenue for the third quarter of 2026 to be in the range of $63 million to $73 million. The midpoint of $68 million includes approximately $43 million of product revenue and $25 million of development revenue. Please note that our revenue guidance for the third quarter excludes approximately $17 million of product revenue that we would have expected to ship in the third quarter but is now expected to be delivered in future quarters.— Joseph “Joe” Corso, CFO, 2026-08-06
Management tone: Management’s posture shifted from an unqualified “exceptional quarter” in Q1 2026 to “another strong quarter” with a caveat in Q2 2026. On the call they quantified the ~$17M revenue exclusion, named optics and China as the cause, dated the onset to the past handful of weeks, and said it is not a manufacturing problem. They were direct on JLWS and its ceiling, reframed defense supply-chain exposure as mostly commercial and indirect, and deflected details on space.
Management Guidance
For Q3 2026, management guided revenue to $63M–$73M, with midpoint $68M including approximately $43M product revenue and $25M development revenue. The guide excludes approximately $17M of product revenue now expected in future quarters. Management guided total gross margin of 24%–30%, product gross margin of 34%–40%, development gross margin of approximately 8%, adjusted EBITDA of $1M–$7M, and non-GAAP OpEx of $17M–$19M per quarter in H2 2026. The wider range is attributed exclusively to supply chain.
Trajectory
Trailing revenue moved from $61.7M in Q2 2025 to $66.7M, $81.2M, $80.2M and $82.6M in Q2 2026. The growth is driven by directed energy, munitions/kinetic sensing, A&D additive manufacturing and microfabrication, not AI. Total gross margin expanded to 33.1% GAAP in Q1 2026, narrowed to 31.1% in Q2, and Q3 is guided to 24%–30% on lower product volumes. Product gross margin followed the same volume-driven pattern, from a record 43.6% GAAP in Q1 to 41.2% in Q2 and 34%–40% guided for Q3.
The Model
The model projects FY+1 revenue of 315M and EBITDA of 10M (3.2%), and FY+2 revenue of 400.0M and EBITDA of 40M (10.0%). The near-term anchor is defense program conversion and recovery from the optics delay; FY+2 depends on whether JLWS ramps into production and offsets the HELSI-2 wind-down.

What Could Go Right — and Wrong
- JLWS converts its ceiling into funded task orders beyond the $44M initial work and ramps in 2027, more than replacing HELSI-2 as management expects.
- The China optics constraint resolves quickly and the approximately $17M delayed product revenue is recovered in Q4 2026 or early 2027.
- Product gross margin returns to 40% or above as volumes normalize, consistent with management’s “consistent at 40% or above” framing.
- FY2027–28 directed-energy appropriations land near the nearly $400M each-year prototype/procurement figures and the approximately $1B annual total.
- Missile/kinetic sensing and A&D additive demand continue, extending the record A&D product revenue growth.
- The China optics constraint persists into “months to quarters,” pushing revenue into 2027 and pressuring Q4 backlog execution.
- JLWS remains mostly unfunded beyond the $44M initial work or ramps slower than planned, leaving a 2027 gap as HELSI-2 trails off.
- Margins stay compressed: Q3 total gross margin 24%–30%, product gross margin 34%–40%, adjusted EBITDA $1M–$7M, and development gross margin low and variable.
- Customer concentration bites: U.S. Government 36% of revenue, KORD 12%, Raytheon 10%, and two customers 32% of net receivables.
- Longmont build-out timing and spend stay undisclosed, leaving capacity for a faster JLWS ramp unclear.
Looking Ahead
Over the next 12 months, the key tests are Q3 2026 execution against the $63M–$73M guide, recovery of the approximately $17M delayed optics revenue, the HELSI-2 1 MW demonstration late in 2026, and the start of the JLWS ramp into 2027. Management also points to FY2027–28 appropriations for directed energy and potential HADES announcements.
- Q3 2026Q3 results and JLWS — Tests $63M–$73M guide and first JLWS revenue contribution.
- Late 2026HELSI-2 1 MW demo — Tests CBC architecture underpinning HADES and JLWS.
- Q4 2026Q4 backlog execution — Management calls backlog execution a question mark.
- 2027JLWS ramp — Tests whether JLWS more than replaces HELSI-2.
- FY2027–28Directed-energy appropriations — President’s-budget requests flow through Congress; can be delayed.
- As early as 2028Operational system demos — Planned demonstrations of operational directed-energy systems.
