Contribution Agreement

On May 21, 2026, Emergen Energy LLC (“Emergen”), a wholly-owned subsidiary of Bimergen Energy Corporation (the “Company”), entered into a Contribution Agreement (the “Contribution Agreement”) with FPU-BEC Development Topco, LLC (the “JV Company”), a Delaware limited liability company affiliated with Cerberus Capital Management, L.P. and its Frontier Power & Utilities (“FPU”) platform. Pursuant to the Contribution Agreement, Emergen contributed 100% of its equity interests in three battery energy storage system (“BESS”) project companies (the “Project Companies”), to the JV Company.

As consideration for the contribution of the Project Companies, the JV Company will (i) issue to Emergen 75 Class B Units in the JV Company, representing 7.5% of the total outstanding equity interests, and (ii) distribute to Emergen a reimbursement payment of $1,176,159.00 (the “Reimbursement Amount”) payable within 10 business days of the execution of the Contribution Agreement.

The closing of the Contribution Agreement occurred simultaneously with its execution on May 21, 2026 with respect to two of the Project Companies and with respect to the third Project Company, will occur immediately following its acquisition by Emergen, which must occur within 15 business days of the date of the Contribution Agreement. If Emergen fails to consummate the third acquisition, Emergen is required to make a capital contribution to the JV Company in an amount equal to the portion attributable to such project.

The Contribution Agreement contains customary representations and warranties of Emergen relating to, among other things, organization and qualification, authority and enforceability, no conflicts, legal proceedings, non-foreign status, and the absence of brokers. Emergen also made representations and warranties relating to the Project Companies, including organization, ownership, title to project properties, environmental matters, undisclosed liabilities, intellectual property, contracts, permits, compliance with laws, legal proceedings, ERISA, labor matters, affiliate contracts, and taxes.

Joint Development Agreement

Concurrently with the Contribution Agreement, on May 21, 2026, Emergen entered into a Joint Development Agreement (the “JDA”) with the JV Company. The JDA establishes the framework for collaboration between the parties to jointly develop the contributed BESS portfolio and to cooperate in the joint identification, development, and commercialization of additional utility-scale battery energy storage projects with durations of four hours or greater per project in the ERCOT market.

Pursuant to the terms of the JDA, Emergen will be entitled to receive development service payments and milestone-based payments associated with the contributed projects and future project advancement activities. The agreements provide for the potential payment to Emergen of up to approximately $5.69 million in aggregate development fees and milestone payments, including amounts payable for development work completed to date and additional payments tied to the achievement of specified project development milestones and other conditions. Certain payments are payable no later than July 15, 2026, subject to the terms and conditions of the JDA.

Contributed Equity Assignment Agreement

Also on May 21, 2026, Emergen and the JV Company entered into a Contributed Equity Assignment Agreement (the “Assignment Agreement”), pursuant to which Emergen assigned and transferred 100% of the equity interests in the Project Companies to the JV Company, and the JV Company accepted and assumed the Contributed Equity from Emergen.

Membership Interest Purchase Agreement

Additionally, on May 21, 2026, Emergen entered into a Membership Interest Purchase Agreement (the “MIPA”) pursuant to which Emergen acquired 100% of the membership interests in one of the contributed Project Companies for consideration of approximately $643,500, payable in installments tied to specified project development milestones.
