Eos Energy Enterprises, Inc., EOSE
The collaboration between Eos and Cerberus Capital Management creates Frontier Power USA, an autonomous entity designed to develop, finance, and manage a collection of extended-duration battery storage installations utilizing Eos’ specialized zinc bromide-based Z3 platform.
This arrangement combines three critical components: Eos’ comprehensive technology infrastructure, Cerberus’ institutional funding and operational expertise, and performance guarantees from Ariel Green, which validates Z3 system performance and enables project financing to achieve investment-grade ratings with favorable lending conditions.
Cerberus is demonstrating substantial financial commitment. The investment firm pledged $100M in equity capital to establish Frontier Power USA and consented to maintain its current EOSE share lock-up arrangement through year-end 2026.
As compensation, Cerberus will obtain Eos warrants along with majority ownership in Frontier Power USA.
First Quarter Financial Performance Exceeds Expectations
