The company states that these results are presented in a press release dated November 18, 2025, which is attached as Exhibit 99.1. The filing is signed by the Chief Financial Officer and Treasurer, highlighting that this is the formal disclosure of the latest quarterly performance details through the accompanying press release.
Ultralife Corporation reported higher sales but lower profitability for the quarter ended September 30, 2025. Revenue rose to $43,371 from $35,694, driven mainly by Battery & Energy Products and the contribution from the October 2024 Electrochem acquisition. Gross margin slipped to 22.2% from 24.3%, reflecting less favorable product mix, component quality issues and lower factory throughput, leading to an operating loss of $951 and a net loss attributable to Ultralife of $1,220 versus net income of $258 a year earlier.
For the first nine months of 2025, revenue increased to $142,678 from $120,604, while net income attributable to Ultralife declined to $1,524 from $6,118, as higher interest expense and integration and restructuring costs weighed on results. Electrochem, acquired for $48,022 in cash, contributed nine‑month revenue of $23,718. To fund the deal, Ultralife entered a new credit agreement including a five‑year $55,000 term loan, with $50,937 outstanding at a 6.62% borrowing rate and all debt covenants met. Operating cash flow remained solid at $9,501, lifting cash to $9,260.
Ultralife Corporation filed a Form 12b-25 (NT 10-Q) notifying a late filing for its quarterly report for the period ended September 30, 2025. The company cites its integration of Electrochem Solutions, Inc.—acquired from Integer Holdings on October 31, 2024—as the cause, noting that Electrochem’s books and records transitioned from Integer’s systems to Ultralife’s during the third quarter of 2025.
Ultralife states it needs additional time to finalize third quarter results and allow its independent accountants to complete their review without unreasonable effort or expense. The company expects to file the Form 10-Q within the five-day extension under Rule 12b-25, no later than November 17, 2025.
Ultralife Corporation replaced its independent auditor on August 22, 2025, when the Audit and Finance Committee approved ending the engagement with Freed Maxick P.C. and engaged Withum Smith+Brown, PC effective immediately due to Withum's acquisition of certain assets of Freed Maxick. Freed Maxick's audit reports for the years ended December 31, 2023 and December 31, 2024 contained no qualifications on the company’s financial statements, but its report on internal control over financial reporting for 2024 stated the company did not maintain effective internal control because of a material weakness. The company reported no disagreements or reportable events with Freed Maxick for the reviewed periods and furnished Freed Maxick a copy of this disclosure; Freed Maxick provided a letter dated August 25, 2025 responding to the disclosure.
