Eos Energy Enterprises, Inc. announced it successfully launched commercial production on its first state-of-the-art (SotA) manufacturing line after being installed and commissioned in Turtle Creek, Pennsylvania, propelling the Company?s ability to produce Eos Z3TM batteries at scale. Launching commercial production marks a significant milestone in the Company?s operational capabilities and ability to serve the growing long duration energy storage demand. The process of bringing the line into production involved thorough evaluation and validation of critical mechanical processes, software integration and overall line performance.

The Company continues to see future projects becoming larger in size and scale as energy demand increases. With the newly installed SotA manufacturing line, Eos will begin ramping manufacturing capacity over the next six months to 1.25 GWh of annualized manufacturing capacity, with expansion plans for 2 GWh on line 1 with further investment. Successful line 1 implementation is a critical cost out component for the Company?s path to profitability.

When producing at scale, Eos forecasts Z3 production costs to drop by nearly half with improved overhead costs and variable labor utilization. The new line was designed and developed in partnership with ACRO Automation Systems. Over the last several months, Eos and ACRO teams worked in partnership to ensure successful FAT in Milwaukee and now bring the line into full commercial production at Eos? facility in Turtle Creek.

As the demand for safe, long duration energy storage continues to increase, the Company plans to build three additional lines to reach 8 GWh of annualized capacity.
