Aqua Metals has signed a detailed, but non-binding, term sheet to acquire Lion Energy, a U.S. energy storage and software company, in a transaction with aggregate consideration capped at $94.9 million.
Closing consideration would include recognition of $4.1 million previously invested in Lion Energy and $25.8 million of Aqua Metals equity, with additional earn-out equity of up to $65 million tied to Lion Energy achieving more than $55 million of revenue and EBITDA margin goals over 12 consecutive months after closing. A new non-voting Series X Preferred Stock class is contemplated to cap common ownership at 45% overall and 40% for Lion’s majority owner, with automatic conversion into common stock after three years and anti-dilution features.
Conditions include a satisfactory fairness opinion, clean diligence, a new $25 million asset-based credit facility, key offtake and supply agreements, exchange listing approval, and shareholder approvals. Separately, Aqua Metals funded a subordinated, last-out $4.1 million participation in Lion’s existing senior credit facility, fully secured by Lion’s assets but junior to all senior obligations. The companies currently target closing in the second quarter of 2026, with no assurance the deal will be completed.
