EnerSys, the industrial battery maker, has agreed to buy Ultralife Corporation, under an Agreement and Plan of Merger dated October 27, 2026 and filed as an exhibit to EnerSys’s Form 8-K on Tuesday. A newly formed EnerSys subsidiary will launch a tender offer for all outstanding Ultralife shares at $16.00 a share in cash, followed by a merger under Section 251(h) of Delaware law that cashes out any shares not tendered at the same price.

Ultralife, based in Newark, New York, makes batteries and power systems for defence, medical and industrial customers. The agreement sets a minimum tender condition and the usual offer conditions, and gives Ultralife a window to comply with its disclosure obligations before the offer launches; no financing condition is stated in the agreement.
