nLIGHT Provides Update on Preliminary Fourth Quarter 2025 Financial Results

Key Terms

directed energy technical

Directed energy describes weapons or tools that send concentrated beams of energy—such as lasers, microwaves, or particle streams—toward a target to heat, disable, or disrupt it rather than using conventional projectiles. Like using a magnifying glass to focus sunlight on a single spot, these systems can deliver effects at speed and with precision. Investors watch directed energy because it drives defense and high-tech spending, influences regulatory and export rules, and carries long development timelines and maintenance costs that affect company value.

optical sensing technical

Optical sensing uses light—visible, infrared, or other wavelengths—to detect or measure physical conditions such as distance, color, motion, composition, or health of a material or environment. For investors, it matters because these light-based sensors are key components in products and services (think of them as the eyes of a device) that can drive revenue, cost, competitive advantage, and supply-chain exposure across industries from healthcare and manufacturing to consumer electronics and autonomous vehicles.

generally accepted accounting principles financial

Generally accepted accounting principles (GAAP) are a standardized set of rules and practices companies use to record and report their financial results, like a common recipe so dishes from different cooks can be fairly compared. Investors rely on GAAP because it makes company earnings, assets and liabilities consistent and transparent across businesses, helping them compare performance, spot risks, and make informed decisions about buying or selling stock.

CAMAS, Wash.--(BUSINESS WIRE)-- 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. Any investor presentation materials utilized during the conference will be made available on the investor page of the Company’s website at https://investors.nlight.net.
