nLIGHT (LASR) is back on investor radar after reports of an expansion in Torino, Italy, aimed at serving European demand for directed energy solutions and supporting regional supply chain resiliency.

The recent Torino expansion headline sits alongside a period of strong momentum, with a 90 day share price return of 40.23% and a very large 1 year total shareholder return. Defense focused product launches and upbeat commentary from brokers have also kept interest elevated.

With the stock up 40.23% over 90 days, a very large 1 year total shareholder return and analysts lifting price targets close to the current US$78.55 level, you now have to ask: is there still a buying opportunity here, or is the market already pricing in future growth?

Most Popular Narrative: 7.6% Undervalued

At a last close of $78.55 versus a most followed fair value of $85.00, the current price sits below where the narrative model comes out, with that gap tied directly to detailed assumptions about future revenue, margins, and discounting at 8.78%.

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.

Successful transition of amplifier products from R&D to scalable manufacturing demonstrates operational leverage and positions nLIGHT to improve gross margins as production volumes rise and fixed costs are absorbed more efficiently.

Curious what kind of revenue path and margin rebuild would need to play out for that fair value to stack up. The narrative leans on faster top line expansion, a shift toward higher margin defense and development work, and a rich future earnings multiple that is far from what the broader US Electronic industry currently trades on. The full breakdown shows exactly how those moving parts are stitched together into that $85.00 figure.

Result: Fair Value of $85.00 (UNDERVALUED)

However, this narrative can quickly weaken if defense focused revenue faces funding delays, or if commercial industrial demand remains soft and weighs on overall growth.

Another lens on valuation

While the narrative model suggests nLIGHT is 7.6% undervalued at $78.55 versus a fair value of $85.00, the current P/S ratio of 15.3x paints a very different picture. That is much higher than both the US Electronic industry at 2.9x and an estimated fair ratio of 2.8x. This points to a lot of optimism already in the price. The question is whether you think future execution can keep supporting that kind of premium.
