Ultralife

What Ultralife does

Ultralife Corporation (NASDAQ: ULBI), founded in 1990 and headquartered in Newark, New York, designs, manufactures, and supports mission-critical battery and RF power solutions for Government & Defense, Medical, Industrial, and Oil & Gas markets. The company operates two product divisions — Battery & Energy Products (non-rechargeable lithium cells including Thin Cells® and ER Generation X Cells, rechargeable lithium-ion and NiCd packs, chargers, and accessories) and Communications Systems (RF amplifiers, satellite communications equipment, power supplies, speakers, and ruggedized server enclosures such as the HPE EL8000 case). Ultralife's portfolio includes more than 350 standard products plus engineered solutions for extreme environments, with proprietary technologies such as 1.1mm Thin Cells, conformal wearable batteries, the X5 hot-swap medical cart power system, and 400+ Whr/Kg lithium thionyl chloride cells.

The business model combines direct Tier 1 OEM and government sales with a solutions engineering overlay that integrates Ultralife into customer product platforms for 10-15+ year lifecycles, including cost-down exercises, design optimization, and supply chain scaling. Hardware sales dominate revenue, supplemented by professional services revenue from custom engineering. The company sells through a direct enterprise field sales force and a public e-commerce storefront, and supports customers through 9 global locations including manufacturing facilities in Newark (NY) and Raynham (MA) and additional sites in North America, Europe, and Asia.

Ultralife is publicly traded with approximately 30.68% institutional ownership and reports under SEC filings. Recent strategic activity has been focused on inorganic expansion: the company acquired Excell Battery Group for $19 million in September 2025 and Electrochem Solutions from Integer Holdings in 2025, both consolidating North American battery capabilities. Partnerships with Hewlett Packard Enterprise (ruggedized 5G servers), Karta Healthcare (medical cart power, with the March 2026 X5-SuperLite launch), and Iris Technology (Power HIVE tactical power node) extend the addressable surface into tactical edge computing and modern medical environments. Despite these moves, Q1 2026 revenue declined 6.5% year-over-year to $47.4 million amid Communications Systems order delays and a Newark facility power outage, even as backlog reached a record $115.1 million.
