Eos Energy Enterprises Reports Preliminary Q1 Revenue, Highlights Record Output and Capacity Expansion PITTSBURGH, PA, April 9, 2026 — Eos Energy Enterprises, Inc. (NASDAQ: EOSE) ("Eos" or the “Company”), an American energy company and the leading innovator in designing, sourcing, manufacturing, and providing zinc-based battery energy storage systems (BESS), today announced that it expects to report preliminary first quarter 2026 revenue of $56 - $57 million, as record shipments and manufacturing output demonstrated continued progress in the Company’s operational scaling. Following its most recent earnings update, the Company is providing a preliminary revenue range to offer additional visibility into first quarter performance. The expected results reflect continued operational improvements and increased manufacturing consistency. Building on fourth quarter of 2025 operational improvements, Eos delivered meaningful first quarter of 2026 gains in manufacturing performance. Targeted operational initiatives focused on supplier quality control, lean process discipline, and equipment optimization are now delivering measurable throughput, repeatability, and overall execution. Shipments remain on track with customer contractual commitments, reinforcing strong alignment between manufacturing output and project delivery timelines. Key first quarter achievements include: • Record quarterly shipments, increasing 17% quarter-over-quarter • Record quarterly battery output, increasing 10.4% quarter-over-quarter • Record quarterly bipolar output, increasing 10.6% quarter-over-quarter • 22% sequential improvement in bi-polar automation yields, signaling increased process stability and manufacturing consistency Strong execution drove unit shipment growth during the quarter. Quarterly revenue reflected a higher mix of DC-system projects versus AC-coupled projects which include additional equipment sales that vary by customer configuration. Eos has also recently achieved a key milestone in the development of its second production line (“Line 2”). The Company successfully completed Factory Acceptance Testing for its second battery line. Following site acceptance testing, initial production is targeted for the end of the second quarter. Line 2 was purpose-built to expand manufacturing capacity while increasing efficiency. Enhancements incorporated into the battery line include a single-piece flow configuration, increased process redundancy, and advanced pick-and-place gantry systems to enable faster cycle times and repeatability. Combined with the optimized Thorn Hill facility layout, these enhancements are expected to drive meaningful performance gains. • ~86% reduction in raw material travel distance across end-to-end operations • ~40% reduction in battery line length driven by a single-piece flow design
2 As demand grows and customer requirements evolve, Eos is focused on converting that demand into executed projects, reliably, and at scale. Achieving this requires more than just manufacturing capacity; it requires strong project execution from inquiry to system operation. In support of this, Eos is adding industry veterans with proven experience in delivering complex projects. Erik Todd joined Eos as Executive Vice President, Sales, bringing more than 20 years of experience leading large-scale energy and infrastructure sales organizations where he managed a global $1B+ industrial infrastructure business. Cristi Thomas joined Eos as Senior Vice President, Projects & Delivery, with experience leading complex, infrastructure scale energy projects across development, construction, commissioning, and operations. These additions strengthen Eos’ ability to convert capacity into executed projects and deliver on customer commitments. Eos will report its full first quarter of 2026 financial results in May.
