nLIGHT, Inc. Announces Second Quarter 2026 Results
Record revenues of $82.6 million increased 34% year-over-year
Record quarterly Products revenue of $59.4 million increased 45% year-over-year

CAMAS, Wash., August 6, 2026 - 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 second quarter of 2026.

“Our second quarter results represent another strong quarter of execution for nLIGHT with total revenue, gross margin and Adjusted EBITDA at or above our expectations, driven by continued strength in our key defense and advanced manufacturing markets,” commented Scott Keeney, nLIGHT’s Chairman and Chief Executive Officer. “Our pipeline of new opportunities in directed energy continues to expand, with the Department of War’s Joint Laser Weapon Systems contract as the latest example. Our laser sensing and advanced manufacturing opportunities also continue to grow, providing us with a broad base of new and existing programs that we expect will continue to provide attractive long-term growth opportunities for nLIGHT.”

Record revenues of $82.6 million for the second quarter of 2026 were up 33.8% compared to $61.7 million for the second quarter of 2025. Gross margin was 31.1% for the second quarter of 2026 compared to 29.9% for the second quarter of 2025. GAAP net loss for the second quarter of 2026 was $1.3 million, or $0.02 per diluted share, compared to net loss of $3.6 million, or $0.07 per diluted share, for the second quarter of 2025. Non-GAAP net income for the second quarter of 2026 was $9.6 million, or $0.17 per diluted share, compared to non-GAAP net loss of $2.9 million, or $0.06 per diluted share, for the second quarter of 2025. 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 third quarter of 2026, nLIGHT expects revenues to be in the range of $63 million to $73 million. The midpoint of $70 million includes Products revenue of approximately $43 million and Advanced Development revenue of approximately $25 million. Due to supply chain challenges, nLIGHT’s third quarter revenue guidance excludes approximately $17 million of product revenue that nLIGHT would have expected to ship in the third quarter but is now expected to be delivered in future quarters.

nLIGHT expects overall gross margin to be in the range of 24% to 30%, with Products gross margin in the range of 34% to 40% and Advanced Development gross margin of approximately 8%. nLIGHT expects Adjusted EBITDA to be in the range of $1 million to $7 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.

Investor Webcast at 2:00 p.m. Pacific Time, Thursday, August 6, 2026

A webcast to discuss the second quarter results will be held on Thursday, August 6, 2026, at 2:00 p.m. Pacific Time (5:00 p.m. Eastern Time).

Use of Non-GAAP Financial Results

In addition to U.S. GAAP results, this press release contains non-GAAP financial results, including non-GAAP gross margin, 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 gross margin, 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 gross margin as GAAP gross margin adjusted for stock-based compensation 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 gross margin, 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.
