Joe Mastrangelo, CEO of Eos Energy Enterprises, discussed the company's third-quarter 2025 results on its November 2025 earnings call, noting a commercial pipeline of $22.6 billion, a 21% quarter-over-quarter increase, with data centers comprising 22% of the pipeline volume and 64% of projects at six hours or longer duration. He highlighted growing activity in PJM and New York ISO markets, citing the NYERTA bulk storage RFP's requirements for 8-hour systems and in-zone Manhattan deployment as aligning with Eos's technology. Mastrangelo also described a partnership with Frontier, financed by Cerberus, which he said the company views as a platform for European expansion, and emphasized ongoing efforts to simplify operations and improve customer experience. In earlier appearances, Mastrangelo has consistently advocated for U.S.-based manufacturing and domestic supply chains for Eos's zinc-based batteries, stating that bringing production back to the U.S. helped the company during COVID-19. He has described the company's technology as non-flammable, recyclable, and suited for longer-duration storage, while acknowledging lithium-ion's role in electric vehicles. He has also discussed the challenges of scaling a startup, noting that customers "bet their career" on delivery, and has emphasized that all employees are shareholders. In 2021, he projected $5 million in total revenue for that year with shipments shifting to 2022, and in 2020, he cited a $500 million pro forma market capitalization when the company went public via SPAC.
