Why it matters

Ultralife's strong performance in its Battery & Energy Products segment, which accounts for the majority of its business, demonstrates the company's ability to navigate market challenges and capitalize on growth opportunities.

The details

For the quarter ended Dec. 31, 2025, Ultralife posted an operating loss of $10.6 million and a GAAP net loss of $7.4 million, or $0.45 per share. The company said results included a one-time non-cash intangible asset impairment charge tied to its transition from multiple sub-brands to the Ultralife master brand. Ultralife's Battery & Energy Products segment drove the quarter's top-line growth, with revenue up 15.1% to $45.9 million, driven by a 39.6% increase in medical sales, a 20.4% increase in industrial and other commercial sales, and a 1.2% increase in government defense sales. These gains were partially offset by a 3.6% decline in oil and gas market sales. Communications Systems segment revenue declined 35.2% to $2.6 million, which the company attributed to timing of expected orders that were delayed by the U.S. government shutdown.
