nLIGHT (LASR) Faces Premium Valuation Scrutiny, Is The Stock Still Overvalued?

Simply Wall St · 19h ago

nLIGHT (LASR) is drawing fresh attention after a multi-year share price climb that has left the stock trading on a rich sales-based valuation compared with many laser industry peers.

Recent trading in nLIGHT has cooled. The 30-day share price return is down 15.58% and the 90-day move is down 38.45%, even though the year-to-date share price return is 3.83% and the 3-year total shareholder return is about 3x. This points to long term momentum but fading short term enthusiasm around a valuation that already prices in a lot of optimism.

That mix of a three year share price surge and a sharp recent pullback leaves a simple dilemma. Does nLIGHT’s current premium valuation still offer enough upside to compensate for the hit if sentiment turns?

Most Popular Narrative: 56% Undervalued

On the most followed view, nLIGHT’s narrative fair value of $90.71 sits well above the last close at $39.84. This puts the recent pullback against a much higher long term earnings story built on defense lasers and advanced manufacturing exposure.

The rapid growth and expanding pipeline in aerospace and defense, particularly around high-power laser solutions (e.g., HELSI-2 program, DE M-SHORAD, Golden Dome initiative, and increased directed energy orders internationally), positions nLIGHT to benefit from rising global defense spending and modernization, supporting strong multi-year revenue growth.

Increasing adoption of advanced laser technologies for automation, smart manufacturing, and additive manufacturing (especially in high-growth EV, clean energy, and microfabrication segments) underpins long-term demand for nLIGHT's differentiated products, providing a runway for sustained top-line expansion.

See why 15 investors see nLIGHT as 56% undervalued.

Result: Fair Value of $90.71 (UNDERVALUED)

Still, nLIGHT’s heavy reliance on aerospace and defense programs, along with the execution risk in scaling amplifier manufacturing, leaves the upbeat narrative vulnerable if contracts slip or ramp-up stumbles.

Another View: nLIGHT Looks Expensive On Cash Flows

High-conviction narratives and analyst targets point to nLIGHT as 56% undervalued based on future earnings potential. The SWS DCF model paints a very different picture. On projected cash flows, nLIGHT’s estimated value is $9.44 per share, which makes the current $39.84 price look materially overvalued. Which story do you trust more: the long term growth path, or the cash in and out?
