Overview

Ultralife Corporation (NASDAQ: ULBI) has released its annual 10-K report for the fiscal year ended December 31, 2025. The report provides comprehensive information about the company’s financial performance, operational highlights, risk factors, and strategic direction. Here is a detailed breakdown of the most important information for shareholders and potential investors.

Key Points and Highlights

• Market Value and Share Count:
  As of June 30, 2025, Ultralife’s aggregate market value of common stock held by non-affiliates was approximately \$90.47 million. As of March 20, 2026, the company had 16,656,503 shares of common stock outstanding.
• Filer Status:
  Ultralife is classified as an accelerated filer and a smaller reporting company, but not an emerging growth company. The company has complied with all SEC reporting requirements and interactive data filings.
• Segment Reporting:
  Ultralife operates two primary segments:
  • Battery & Energy Products: Includes Lithium 9-volt, cylindrical, thin cell, and other non-rechargeable batteries; rechargeable batteries; uninterruptable power supplies; charging systems and accessories.
  • Communications Systems: RF amplifiers, power supplies, connector assemblies, amplified speakers, equipment mounts, man-portable and integrated communications systems for fixed or vehicle applications.

  Segment contribution, defined as gross profit less direct SG&A and R&D expenses, is the main performance indicator.

• Employees:
  As of December 31, 2025, Ultralife employed 678 people (525 in production, 92 in sales/admin, 61 in R&D). None are union-represented.
• Corporate Operating Expenses:
  Corporate operating expenses, including business acquisitions and non-recurring actions, were \$24.84 million in 2025 (up from \$10.22 million in 2024). This includes a one-time \$12.18 million intangible asset impairment charge from global rebranding.
• Trademarks:
  The company owns and markets products under numerous trademarks, but its rebranding initiative will eliminate or de-emphasize certain trademarks going forward.
• Regulatory Compliance:
  Ultralife complies with EU Battery Directive, China’s hazardous substances laws, and the US Dodd-Frank Act for “conflict minerals.” The company filed its Form SD on time and continues to monitor supply chain compliance.
• Credit Facilities:
  Ultralife operates under a senior secured term loan facility of \$55 million and a revolving credit facility of \$30 million. Rising interest rates are noted as a risk for increased borrowing costs.

Risks and Price-Sensitive Information

• Economic Conditions:
  Ultralife faces continued risks from inflation, tariffs, supply chain disruptions, and changing government trade policies. Although conditions improved slightly in 2025, these factors still pose a threat to margins and profitability.
• Customer Concentration:
  The company is reliant on certain key customers, including large defense contractors. Reductions or delays in US and foreign military spending could materially affect revenues.
• Product Development & Competition:
  Ultralife invests in new product development, but there is no guarantee of success, market adoption, or profitability. Competition is intense, especially from foreign (notably Asian) manufacturers competing on price.
• Supply Chain & Pricing:
  Continued supplier price increases, tariffs, and requirements for US-sourced components may pressure margins if the company cannot pass costs to customers or offset with manufacturing efficiencies.
• Cybersecurity:
  The company has a Security Steering Committee and processes in place for IT and cybersecurity risk management. No material cybersecurity incidents were reported, but this remains an ongoing risk.
• Intangible Asset Impairment:
  The \$12.18 million write-down on tradenames/trademarks in Q4 2025 is a significant, non-cash event that impacts reported earnings and could be considered price-sensitive.
• China Operations:
  The company operates a facility in China, which exposes it to unique risks: regulatory changes, labor laws, currency fluctuations, trade restrictions, and geopolitical uncertainties.
• Oil & Gas Sector Exposure:
  The company’s results are affected by volatility in oil prices and downhole drilling activity.
• Safety Risks:
  Lithium batteries pose safety risks (fire/explosion) and potential liability claims. Ultralife maintains insurance, but accidents could significantly impact cash flow and reputation.
• Pandemic Risk:
  The report notes the ongoing risk of future pandemics causing supply chain disruption, affecting employee and customer health, and delaying product delivery.
• Intellectual Property:
  Risks exist from potential challenges to proprietary IP and patents, which could allow competitors to produce similar products or force costly alterations.
• Conflict Minerals:
  Compliance with Dodd-Frank increases operational costs and risks; supply chain complexity makes verification difficult.
• Share Price Volatility:
  The company warns that quarterly/annual results and share price may fluctuate substantially due to order timing, product introductions, government demand, supply chain disruptions, and one-time costs.

Strategic Initiatives

• Rebranding:
  Ultralife undertook a global rebranding initiative, resulting in the \$12.18 million impairment charge. This will streamline its trademark portfolio and may affect brand recognition in certain markets.
• Growth Strategy:
  The company has a rolling three-year strategic plan to expand sales of battery and energy products, increase international distributor networks, and invest in design and assembly capabilities.
• Focus on OEMs:
  Targeting OEM customers and responding to Requests for Proposals is central to growth, with a view to integrate Ultralife batteries in OEM products for longer-term revenue opportunities.

Other Notable Information

• SEC Compliance:
  Ultralife filed all required reports and proxy statements. No unresolved staff comments were noted for the period.
• Corporate Governance:
  The company maintains a succession plan for key management, updated annually and presented to the Board.
• Insurance:
  Ultralife operates a comprehensive global insurance program to mitigate litigation and operational risks.

Conclusion

Ultralife Corporation’s 2025 10-K contains significant information relevant to shareholders, including a notable intangible asset impairment from rebranding, robust compliance with regulatory requirements, ongoing risks from supply chain, competition, and economic conditions, and a clear strategic focus on expanding OEM partnerships and international markets. The impairment, continued exposure to defense spending and oil/gas sectors, and competitive landscape are all factors that could materially impact share value.
