Eos Energy Enterprises Receives $87 Million Advance Under U.S. Department of Energy Loan to Fund Second Production Line at Thorn Hill First advance under second tranche brings total drawn under the DOE facility to $178 million and supports 4 GWh of annual battery manufacturing capacity in Western Pennsylvania PITTSBURGH, PA September 14, 2026 Eos Energy Enterprises, Inc. (NASDAQ: EOSE) ( Eos or the Company ), America s leading innovator in designing, manufacturing, and providing zinc-based long-duration energy storage (LDES) systems sourced and manufactured in the United States, today announced it has received an $87 million first advance under the second tranche of its loan agreement with the U.S. Department of Energy s (DOE) Office of Energy Dominance Financing (EDF). The advance reimburses 80% of eligible costs associated with the Company s Thorn Hill manufacturing facility in Warrendale, Pennsylvania. Eos has now drawn a total of approximately $178 million of its DOE facility since 2024. Line 2 entered commercial production in June 2026 and is being ramped toward its designed annual manufacturing capacity of approximately 2 GWh. Upon completion of the planned relocation of line 1 to Thorn Hill, subject to lender approvals, Eos expects Thorn Hill to support approximately 4 GWh of annual manufacturing capacity across two lines. Loan funding from the Office of Energy Dominance Financing has been critical in scaling Eos, said Alessandro Lagi, Chief Financial Officer of Eos. This advance reimburses a significant portion of the investment we have already made in Line 2 and returns that capital to the balance sheet, giving us more room to invest in the business while maintaining a disciplined approach to growth. Running two lines under one roof drives more efficient use of our engineering, support resources, and labor, said John Mahaz, Chief Operating Officer of Eos. This enables the operation to increase productivity and optimize manufacturing cost. Eos expects to create jobs across 4 shifts to staff Line 2 in the Western Pennsylvania facility. The line continues to ramp toward full production as additional shifts come online, consistent with the Company s phased manufacturing scale-up strategy.
