Ultralife Corporation Reports Second Quarter Results

NEWARK, N.Y. – August 7, 2026 -- Ultralife Corporation (NASDAQ: ULBI) reported operating results for the second quarter ended June 30, 2026 with the following results:

• Sales of $47.9 million compared to $48.6 million for the 2025 second quarter

• Gross profit of $13.9 million, or 28.9% of revenue, compared to $11.6 million, or 23.9% of revenue, for the 2025 second quarter; excluding a $1.1 million net IEEPA refund received in the 2026 second quarter, gross margin was 26.6%

• Operating income of $3.4 million, including one-time costs of $0.9 million, compared to $2.3 million including one-time costs of $0.3 million for the 2025 second quarter

• GAAP EPS of $0.15 compared to $0.05 for the 2025 second quarter

• Adjusted EBITDA of $6.1 million compared to $4.1 million for the 2025 second quarter

• Backlog of $117.5 million compared to $115.1 million exiting the first quarter of 2026

“For the second quarter we delivered a 760-basis point improvement in gross profit margin compared to the first quarter, including the contribution of the net IEEPA refund. This improvement reflects measurable benefits realized to date from our initiatives to address manufacturing inefficiencies along with favorable sales mix. Our Communications Systems business is poised to produce revenue gains as new products move through the capture phase, and continues to expand its opportunity funnel while preparing to launch multiple new products later this year in support of government/defense programs. At the same time, we are advancing a diverse set of product development programs in our Battery & Energy Products business including programs to support water-based defense drone applications. Several of these programs are expected to transition into production later this year while we continue to execute our backlog. These multi-year revenue opportunities combined with our ongoing gross margin improvement initiatives, reinforce our outlook for profitable growth in 2026,” said Mike Manna, President and Chief Executive Officer.

Second Quarter 2026 Financial Results

Revenue was $47.9 million, a decrease of $0.6 million, or 1.3%, as compared to revenue of $48.6 million for the second quarter of 2025. Battery & Energy Products sales decreased 3.7% to $44.2 million compared to $45.9 million last year. The year-over-year decrease reflects a 4.7% decline in commercial sales due to an 8.7% decline in oil & gas and industrial sales offsetting a 7.2% increase in medical battery sales, and a 1.4% decline in government/defense sales due to the shipment of a very large order for an allied country last year. Communications Systems sales increased by 39.3% to $3.8 million compared to $2.7 million for the same period last year. Our total backlog exiting the second quarter was $117.5 million, the highest level in the Company’s history, compared to $115.1 million exiting the first quarter of 2026 and $84.5 million exiting the second quarter of 2025.

Gross profit was $13.9 million, or 28.9% of revenue, compared to $11.6 million, or 23.9% of revenue, for the same quarter a year ago. Battery & Energy Products gross margin was 28.3%, compared to 23.6% last year, primarily due to favorable product mix and the refund of the IEEPA tariffs in the current period. Communications Systems gross margin was 36.3% compared to 28.4% last year, primarily due to sales mix.

Operating expenses were $10.4 million, compared to $9.3 million for the second quarter of 2025, reflecting an increase in new product development costs related to continued investment in our product offering, and one-time, non-recurring costs of $0.9 million primarily related to litigation expenses incurred for our cyber-insurance claim and the completion of certain consulting costs to help expedite our gross margin improvement. Operating expenses were 21.8% of revenue compared to 19.2% of revenue for the year-earlier period.

Operating income was $3.4 million compared to $2.3 million last year.

Other expense was $0.5 million primarily comprised of interest expense from the financing of our Electrochem acquisition partially offset by the second quarter estimated portion of a refundable tax credit for certain qualifying battery cells and packs we manufacture under the 45X Advanced Manufacturing Production Tax Credit. This compares to $1.1 million for the year-earlier period primarily reflecting the Electrochem acquisition financing and net foreign currency losses.

Net income attributable to Ultralife Corporation was $2.5 million or $0.15 per basic and diluted share on a GAAP basis, compared to $0.9 million or $0.05 per basic and diluted share for the second quarter of 2025.

Adjusted EBITDA, defined as EBITDA including non-cash, stock-based compensation expense and one-time costs not reflective of our ongoing operations, was $6.1 million for the second quarter of 2026, or 12.8% of sales, compared to $4.1 million, or 8.5% of sales, for the year-earlier period. On a trailing twelve-month basis, adjusted EBITDA was $17.1 million or 9.1% of sales.

Non-GAAP Financial Measures

Adjusted EBITDA

In evaluating our business, we consider and use adjusted EBITDA, a non-GAAP financial measure, as a supplemental measure of our operating performance in addition to GAAP financial measures. We define adjusted EBITDA as net income attributable to Ultralife Corporation before net interest expense, provision for income taxes, depreciation and amortization, and stock-based compensation expense, plus/minus expense/income that we do not consider reflective of our ongoing continuing operations. We reconcile adjusted EBITDA to net income attributable to Ultralife Corporation, the most comparable financial measure under GAAP. Neither current nor potential investors in our securities should rely on adjusted EBITDA as a substitute for any GAAP measures and we encourage investors to review the following reconciliation of adjusted EBITDA to net income attributable to Ultralife Corporation.
