The arrangement combines three critical elements: Eos’ fully integrated technology infrastructure, Cerberus’ institutional financing capabilities and operational expertise, and a performance guarantee from Ariel Green that ensures Z3 system performance and facilitates access to investment-grade project financing at favorable rates. Cerberus is backing the venture with substantial capital. The investment firm pledged $100M in equity funding to establish Frontier Power USA and agreed to maintain its existing EOSE share lock-up arrangement through December 2026. As compensation, Cerberus will receive Eos warrants and majority ownership in Frontier Power USA.

Net income attributable to common shareholders totaled $508.88M during the quarter, up significantly from $15.14M in Q1 2025.
