Is nLIGHT, Inc. (LASR) A Good Stock To Buy Now?

Why It Matters

The company’s rapid defense‑driven growth and expanding backlog could translate into sustained margin expansion, making LASR a potentially high‑reward play despite its lofty forward P/E ratio.

Key Takeaways

• Laser Products generate 68.6% of 2025 revenue with 39.2% margin.
• Aerospace & Defense accounts for 67% of revenue, up 60% YoY.
• 2025 revenue rose 31.6% to $261.3 million; EBITDA turned positive.
• Backlog $161.6 million and $184.4 million unfunded contracts provide visibility.
• $201 million equity raise strengthens balance sheet for defense scaling.

Pulse Analysis

nLIGHT’s positioning in the directed‑energy market reflects a broader shift toward laser‑based solutions in aerospace and defense. The company’s vertically integrated semiconductor and fiber‑laser stack gives it a technological edge, enabling it to meet stringent military specifications and secure design‑win contracts with prime contractors such as Northrop Grumman and Raytheon. As the U.S. Department of Defense ramps up funding for high‑power laser programs, firms that can deliver reliable, scalable platforms are poised for rapid adoption, and nLIGHT’s focus on both industrial and defense applications diversifies its addressable market.

Financially, nLIGHT demonstrated a clear inflection point in 2025. Revenue climbed to $261.3 million, driven largely by a 60% surge in aerospace and defense sales, while gross margins expanded to 29.8% as production efficiencies improved. The shift from a loss‑making to a positive Adjusted EBITDA of $23.5 million underscores operating leverage as defense contracts scale. A robust backlog of $161.6 million and $184.4 million in unfunded government contracts provide concrete near‑term visibility, and the recent $201 million equity raise equips the company with the capital needed to expand manufacturing capacity and meet growing demand.

For investors, the key consideration is whether the high forward P/E of roughly 244 can be justified by future earnings growth. If nLIGHT successfully converts its advanced‑development projects into high‑margin laser‑product revenue, the company could sustain margin expansion and deliver outsized returns. However, concentration risk—both in a few major defense customers and reliance on government funding—remains a caveat. Analysts will watch contract award pipelines, production ramp‑up progress, and any pricing pressure in the competitive laser market to gauge the durability of the bullish thesis.
