Financial Performance and Operational Resilience

Ultralife's recent financial performance reflects both the strategic benefits of its acquisition and the impact of external headwinds. For Q2 2025, the company reported revenues of $48.6 million, a 13% increase year-over-year, largely driven by the Electrochem acquisition. However, gross profit margin compressed by 300 basis points to 23.9% from 26.9% in Q2 2024. Operating income fell to $2.3 million (4.6% of revenues) from $3.9 million (9.1% of revenues) in the prior year, reflecting lower Communications Systems sales, reduced Battery & Energy Products gross margin, and increased operating expenses, including $0.3 million in one-time acquisition-related costs. Net income attributable to Ultralife Corporation was $0.9 million, or $0.05 per share (GAAP), compared to $3.0 million, or $0.18 per share, in Q2 2024. Adjusted EPS, excluding non-cash deferred taxes, was $0.07.

For the six months ended June 30, 2025, consolidated revenues grew 17% to $99.3 million. Battery & Energy Products revenues increased 28.6% to $92.2 million, including Electrochem, while Communications Systems revenues declined 46.2% to $7.1 million due to order timing delays. Operating cash flow for the first half was $9.3 million, demonstrating solid cash generation.

Ultralife is actively addressing margin pressures through operational efficiencies. The closure of its Mississauga operation in Q2 2025 eliminated fixed costs and redundant operations. A major lean project at the Electrochem site in Q2 2025 eliminated the need to hire 30 additional employees, supporting increased cell sales and vertical integration. These efforts, alongside material cost deflation and strategic pricing, are critical for stabilizing and improving gross margins.

The company's liquidity remains strong, with cash increasing to $10.9 million at June 30, 2025, from $6.9 million at December 31, 2024.

Ultralife is ahead of schedule on debt repayment, reducing principal by $3.4 million in H1 2025, exceeding the full-year amortization requirement of $2.8 million. This was significantly aided by the receipt of $1.8 million in Employee Retention Credit (ERC) funds, which were entirely applied to debt. As of June 30, 2025, $51.6 million remained outstanding on the Term Loan, with no draws on the $30 million Revolving Credit Facility, and the company was in full compliance with all debt covenants.

Outlook & Growth Catalysts

Management expresses cautious optimism for the second half of 2025 and into 2026, anticipating improved results. The Communications Systems business is expected to rebound from a tough first half, with approximately $2.7 million in delayed Q2 orders pushed to the second half. Early purchase orders from long-term new product programs for the battery business, a rebound in demand from medical and oil & gas customers, and sustained growth in global defense spending are anticipated. The expanding opportunity pipeline across both businesses, with "chunks of additional revenue" from new products, is expected to drive growth.

Management's priorities remain converting long-term new product development efforts into revenue, advancing vertical integration in the oil & gas segment, and maintaining a strong focus on operational efficiency initiatives to deliver sustainable profitable growth. The company expects to see benefits from qualifying Electrochem cells with oil & gas customers in 2026.
