Frontier Power USA ("FPUSA"), a long-duration energy storage development and investment company, today announced a strategic framework with Stella Energy Solutions ("Stella"), a U.S. utility-scale clean energy platform, which would provide Stella with the opportunity to work alongside FPUSA in executing on its current LDES-focused pipeline, and create a path for FPUSA to acquire and convert Stella's late-stage pipeline of more than 2 GWh of battery energy storage system ("BESS") development projects; the parties expect to memorialize the terms of the framework in definitive agreements. The strategic framework will target conversion of Stella's pipeline utilizing FPUSA's previously announced 2 GWh capacity reservation agreement with Eos Energy Enterprises, Inc. (NASDAQ:EOSE) ("Eos").

The strategic framework expands the working relationship between FPUSA and Stella, which has been tapped as the execution partner for the previously announced 480 MWh portfolio of long-duration BESS projects acquired from Bimergen Energy Corporation. Under the strategic framework, it is expected that Stella will serve as a designated execution partner for FPUSA across its development pipeline and that FPUSA will receive exclusive evaluation rights on projects in Stella's pipeline that meet FPUSA's investment criteria.
