Third consecutive quarter of record Aerospace & Defense revenue

nLIGHT, Inc. (Nasdaq: LASR), a leading provider of high-power lasers for mission critical directed energy, optical sensing, and advanced manufacturing applications, today reported financial results for the third quarter of 2025.

“3Q 2025 represented another solid quarter of execution for nLIGHT with record revenue from our A&D markets driving our results,” commented Scott Keeney, nLIGHT’s President and Chief Executive Officer. “I am particularly pleased with the expansion of our products gross margin, which was 41% in the quarter, and the growth in our Adjusted EBITDA, both of which demonstrate the leverage that is inherent in our operating model. We expect continued sequential A&D revenue growth in the fourth quarter as many of the programs previously announced continue to ramp. As a result, we expect full year 2025 A&D revenue growth to exceed our prior outlook for A&D growth of at least 40% year-over-year."

Third Quarter 2025 Financial Highlights

Revenues of $66.7 million for the third quarter of 2025 were up 18.9% compared to $56.1 million for the third quarter of 2024. Gross margin was 31.1% for the third quarter of 2025 compared to 22.4% for the third quarter of 2024. GAAP net loss for the third quarter of 2025 was $6.9 million, or $0.14 per diluted share, compared to net loss of $10.3 million, or $0.21 per diluted share, for the third quarter of 2024. Non-GAAP net income for the third quarter of 2025 was $4.3 million, or $0.09 per diluted share, compared to non-GAAP net loss of $3.7 million, or $0.08 per diluted share, for the third quarter of 2024. Reconciliations of the non-GAAP metrics presented here to the most directly comparable GAAP metric have been provided in the tables included at the end of this release.

Outlook

For the fourth quarter of 2025, nLIGHT expects revenues to be in the range of $72 million to $78 million. The midpoint of $75 million includes Products revenue of approximately $55 million and Advanced Development revenue of approximately $20 million. nLIGHT expects overall gross margin to be in the range of 27% to 32%, with Products gross margin in the range of 34% to 39% and Advanced Development gross margin of approximately 8%. nLIGHT expects Adjusted EBITDA to be in the range of $6 million to $11 million.

We have not reconciled our outlook for Adjusted EBITDA because unrealized and realized foreign exchange gains and losses cannot be reasonably calculated or predicted nor can the probable significance be determined at this time. Accordingly, a reconciliation is not available without unreasonable effort.

Use of Non-GAAP Financial Results

In addition to U.S. GAAP results, this press release contains non-GAAP financial results, including Adjusted EBITDA, non-GAAP net income (loss) and non-GAAP net income (loss) per share, basic and diluted. We use Adjusted EBITDA to help us evaluate our business, measure our performance, identify trends affecting our business, formulate business plans and make strategic decisions. In addition to our results determined in accordance with GAAP, we believe Adjusted EBITDA is a meaningful measure of performance as it is commonly utilized by us and the investment community to analyze operating performance in our industry. Similarly, we believe that providing non-GAAP net income (loss) and non-GAAP net income (loss) per share, basic and diluted, is useful to our investors as they present an informative supplemental view of our results from period to period by removing the effect of stock-based compensation expense and other non-recurring items. However, the non-GAAP metrics presented herein are specific to us and may not be comparable to similar metrics disclosed by other companies because of differing methods used by other companies in calculating them.

We define Adjusted EBITDA as net income (loss) adjusted for income tax expense (benefit), other non-operating income or expense, interest income or expense, depreciation and amortization, stock-based compensation, acquisition and integration-related costs, and other non-recurring items as determined by management, as applicable. We define non-GAAP net income (loss) as GAAP net income (loss) adjusted for stock-based compensation, amortization of purchased intangibles, acquisition and integration-related costs, and other non-recurring items as determined by management, as applicable. We define non-GAAP net income (loss) per share, basic and diluted, as non-GAAP net income (loss) divided by the weighted-average number of shares outstanding during the respective period plus the dilutive effect of any common stock equivalents during the period in the case of non-GAAP net income (loss) per share, diluted.

Tables presenting the reconciliation of net loss to Adjusted EBITDA, as well as the reconciliation of GAAP to non-GAAP net income (loss) and GAAP to non-GAAP net income (loss) per share, basic and diluted, are included at the end of this press release.
