nLIGHT (LASR) stock soared 14.10% in pre-market trading on Friday, extending its impressive gains from the previous day's regular session. The surge comes on the heels of the company's stellar third-quarter earnings report, which was released after market close on Thursday.

The high-power fiber lasers provider delivered better-than-expected results for Q3, driven by record sales in its Aerospace & Defense (A&D) segment. nLIGHT reported Q3 revenue of $66.74 million, surpassing analyst estimates of $63.89 million and representing an 18.9% year-over-year growth. The company's adjusted EBITDA of $7.11 million also beat consensus expectations, while gross margin expanded significantly to 31.1% from 22.4% in the prior year, indicating enhanced operational efficiency.

Adding to investor optimism, nLIGHT provided a positive outlook for Q4, projecting revenue between $72 million and $78 million. The company anticipates continued sequential growth in A&D revenue and expects full-year 2025 A&D revenue growth to exceed 40%. This strong performance and upbeat forecast have likely fueled investor enthusiasm, contributing to the stock's substantial pre-market gain. With Wall Street maintaining a generally bullish stance on nLIGHT, the company's focus on the high-growth A&D market appears to be paying off, positioning it well for future growth.
