nLIGHT (LASR) drew investor attention after first quarter 2026 results topped analyst expectations, with revenue of US$80.18 million, a shift to positive net income, and management issuing upbeat guidance for the next quarter.

nLIGHT’s share price has been on a strong run, with a 7 day share price return of 25.18%, a 90 day share price return of 52.83% and a year to date share price return of 118.43%. The 1 year total shareholder return is also very large, pointing to momentum that has built rapidly around its recent earnings beat, Torino expansion and growing focus on directed energy programs.

If nLIGHT’s move has you rethinking where high powered laser and defense related technologies could go next, it may be worth scanning the market for other mission critical hardware and automation plays through 30 robotics and automation stocks

With the stock up sharply and trading only a little below the latest analyst price targets, the key question now is whether nLIGHT is still mispriced or if the market is already accounting for much of its future growth.

Most Popular Narrative: 1% Undervalued

nLIGHT’s most followed narrative pegs fair value at $85, almost in line with the last close at $83.81, and leans heavily on directed energy growth and vertical integration to justify that level.

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.

Curious what sits behind that fair value call at almost the same price as today. Revenue stepping up, margins turning, and a future profit multiple that stands out. Want to see which growth, profitability and discount rate assumptions have been stitched together to reach $85 while the stock hovers just below it.

Result: Fair Value of $85 (ABOUT RIGHT)

However, this hinges on defense remaining 66% of sales. Any shift in government programs or further weakness in commercial lasers could quickly challenge that fair value story.

Another View: Rich Sales Multiple Raises a Red Flag

While the fair value narrative lands almost exactly at the current share price, the market is paying a steep premium on sales. nLIGHT trades on a P/S of 16.3x versus 2.7x for the US Electronic industry and 2.9x as the fair ratio, which suggests expectations are packed into today’s price. How comfortable are you paying that kind of mark up for growth that still needs to be delivered?
