Is LASR a Buy? What to Consider in 2026
Short answer
The bull case for LASR (LASR) rests on Directed-energy defense demand: The clearest driver is US government spending on high-energy laser weapons, where nLIGHT supplies lasers and beam-control systems into Army and Navy programs. Revenue (TTM) is ~$290M. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: Valuation is the dominant risk: at a price-to-sales multiple many times the hardware-industry average, the stock is priced for sustained rapid growth, so any deceleration in defense orders could compress the multiple sharply. Whether LASR is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
nLIGHT, Inc. (Nasdaq: LASR) designs and manufactures high-power semiconductor and fiber lasers for three broad markets: aerospace and defense (directed-energy weapons, optical sensing), advanced manufacturing (industrial cutting, welding, additive), and microfabrication. Historically the company leaned on commercial industrial-laser sales, a competitive and cyclical business, but the growth engine has decisively shifted to defense, where nLIGHT supplies high-energy laser systems and beam-control technology to US Army and Navy programs. The company is based in Vancouver, Washington and books a large share of revenue from US government and prime-contractor programs. The investment picture is a re-rating story. Revenue reached a record ~$261 million in full-year 2025 (up ~32%), and Q1 2026 revenue jumped ~55% year over year to ~$80 million with a swing back to a small net profit and expanding gross margins, driven by record aerospace and defense product revenue. Investors have rewarded that pivot aggressively: the market capitalization sits near ~$3.6 billion against roughly ~$290 million of trailing revenue, a price-to-sales multiple far above typical laser and hardware peers. That leaves the stock priced for continued defense-driven growth, so the central question is execution on the directed-energy backlog rather than whether the underlying business is real.
What's the case for buying LASR?
1. Directed-energy defense demand
The clearest driver is US government spending on high-energy laser weapons, where nLIGHT supplies lasers and beam-control systems into Army and Navy programs. Q1 2026 aerospace and defense product revenue hit a record ~$33 million (up ~98% year over year), and management pointed to a defense backlog near ~$110 million. Rising directed-energy budgets are the core bull case.
2. Product scaling and new platforms
nLIGHT is pushing new high-energy laser platforms (branded families like Hades) intended to scale power and be produced at volume. As mix shifts toward these higher-value defense products and production volumes rise, gross margin has improved (to ~33% in Q1 2026 from ~27%), which is central to the profitability story.
3. Balance-sheet capacity to invest
A February 2026 equity offering left the company with roughly ~$333 million in cash and marketable securities as of Q1 2026. That funding gives nLIGHT room to invest in defense manufacturing capacity and development contracts without immediate financing pressure, though the raise also diluted existing holders.
4. Optical-sensing and manufacturing exposure
Beyond weapons, nLIGHT sells lasers for optical sensing (including aerospace and space applications) and for advanced manufacturing. The commercial and industrial side is more cyclical and competitive, but it provides a second demand pool and some diversification beyond direct government programs.
What are the risks to LASR?
Valuation is the dominant risk: at a price-to-sales multiple many times the hardware-industry average, the stock is priced for sustained rapid growth, so any deceleration in defense orders could compress the multiple sharply. Revenue is concentrated in US government and directed-energy programs, which are exposed to federal budget cycles, procurement timing, and program cancellations. The legacy commercial-laser segment faces intense competition and pricing pressure from larger players. Profitability is thin and recent, so a return to losses is possible if mix or volumes weaken, and the February 2026 equity raise diluted shareholders. Lumpy defense revenue recognition can also make quarterly results volatile.
How is LASR valued? (as of MAY 2026)
Snapshot for LASR as of July 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Revenue (TTM): ~$290M
- FY2025 revenue: ~$261M (up ~32%)
- Q1 2026 revenue: ~$80M (up ~55% YoY)
- Market cap: ~$3.6B
- Price-to-sales: ~15x (vs ~3x peers)
- Cash & securities: ~$333M
As of May 2026, nLIGHT is priced as a defense-growth story: a modest revenue base of roughly ~$290 million trailing supports a market cap near ~$3.6 billion, a price-to-sales multiple many times typical laser-hardware peers. The company turned a small quarterly profit in Q1 2026 after a full-year 2025 net loss, so the premium rests on expectations of continued directed-energy revenue growth rather than current earnings.
How do you decide if LASR is a buy?
Rather than asking whether LASR is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold LASR indirectly through an index or sector ETF before adding more.

The bottom line on LASR
The bottom line: LASR's story right now is Directed-energy defense demand, with revenue (ttm) at ~$290M. If you believe that narrative continues, the call is about sizing LASR sensibly and checking overlap with what you own; if you doubt it (the risk: valuation is the dominant risk: at a price-to-sales multiple many times the hardware-industry average, the stock is priced for sustained rapid growth, so any deceleration in defense orders could compress the multiple sharply.), it is not for you. Decide from the thesis, not the ticker. Walnut is not an investment adviser.
