nLIGHT, Inc. (LASR) Stock Price & How to Invest

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.

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.

7 analysts publish price targets on LASR, averaging $90.71 against a $68.80 price as of August 2026, or +31.8%.

Over the last six months there have been 7 raises and 0 cuts among the published actions. A price target is what an analyst published on a date, not a prediction, and sell-side ratings skew positive across the whole market.

We give no verdict on nLIGHT, Inc.. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. 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. The most optimistic published target, $100.00, assumes this works close to its best case.

The case against. 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. The most pessimistic target, $81.00, is roughly what LASR is worth if this bites instead.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see nLIGHT, Inc.'s investor relations page or your broker.

• 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.

Other names that sit close to LASR: same theme, named as a direct competitor, or held beside it in the same funds. Each entry says which. Worth a look if you are thinking about diversification within a thesis rather than concentration on one ticker.

There are three common ways to get LASR exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic portfolio, so LASR sits alongside other stocks that express the same thesis.

Walnut takes the portfolio route. Describe a thesis where LASR fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

LASR is a real, growing defense-laser business trading at a steep sales multiple, so how you view it depends almost entirely on your read of the directed-energy demand ramp.

Whether LASR is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is LASR a buy or a sell?, and where the stock could go from here in the LASR stock forecast.
