nLIGHT, Inc. (NASDAQ:LASR), a leading provider of high-power lasers for mission critical directed energy, optical sensing, and advanced manufacturing applications, today provided limited preliminary results for the fourth quarter of 2025.

The Company expects to report fourth quarter 2025 revenue in the range of $78 million to $80 million, above the high-end of the Company's previously announced fourth quarter guidance range of $72 million to $78 million. The Company expects to report Laser Products revenue of $54 million to $55 million and Advanced Development revenue of approximately $24 million to $25 million. The anticipated upside in revenue is primarily due to the continued strength in the Company's revenue from the Aerospace & Defense market.

"We ended 2025 on a strong note, particularly with respect to the performance of our Aerospace & Defense market," commented Scott Keeney, nLIGHT's President and Chief Executive Officer. "We enter 2026 with good visibility across multiple programs in both directed energy and laser sensing, and we remain well-positioned for near- and long-term growth in Aerospace & Defense."

Scott Keeney, nLIGHT's President and Chief Executive Officer, and Joe Corso, nLIGHT's Chief Financial Officer are scheduled to host meetings with investors at the 28^th Annual Needham Growth Conference in New York, NY on Tuesday January 13^th, 2026.
