Eos Energy Enterprises and TETRA Technologies, Inc. Extend Partnership, Expanding Electrolyte Production Capacity

TURTLE CREEK, Pa., Jan. 09, 2024 (GLOBE NEWSWIRE) -- Eos Energy Enterprises, Inc. (NASDAQ: EOSE) ("Eos" or the “Company”), a leading provider of safe, scalable, efficient, and sustainable zinc-based long duration energy storage systems, today expanded its partnership with TETRA Technologies, Inc. (NYSE: TTI) a leading global energy services and solutions company, designating TETRA as the preferred strategic supplier of electrolyte products for Eos’s new, American made, Eos Z3™ long duration energy storage cube. TETRA is expected to supply a minimum of 75% of the total electrolyte product demand going forward.

“TETRA is a proven global fluid solution provider, and the Eos strategy has centered around finding raw materials being used in other industries to provide both scale and cost efficiencies,” said Joe Mastrangelo, CEO of Eos. “As we scale, we need supply chain partners that can help us achieve growth, reduce cost, and improve overall performance of our battery. This partnership achieves that while we continue to develop a U.S. supply chain.”

The expected demand growth for Long Duration Energy Storage requires increased volume at scale, and with TETRA’s investment in expanded bromine production, Eos is better positioned to achieve the scale necessary over the next several years, while reducing cost per battery and improving overall quality and performance.

Key to the operational success of the Eos Z3™ cube is high purity zinc-bromide, which is part of Eos’ patented electrolyte system. TETRA’s U.S. based patented manufacturing process produces some of the highest purity levels of zinc-bromide (PureFlow®) globally. The electrolyte solution is one of the largest cost components of the Eos Z3 cube and this agreement supports progress on the Company’s path to profitability. The two companies have been working together since 2021 to improve the quality of the electrolyte solution.

“We have been working closely and collaboratively with Eos for years as they transition to their new Z3 technology, and in that time have evolved from only supplying zinc-bromide PureFlow® to now offering the full electrolyte solution,” said Brady Murphy, President and CEO of TETRA Technologies Inc. “This relationship dovetails nicely with our bromine production plans, and we are excited to be part of Eos’s future plans and Inflation Reduction Act objectives.”

This four-year agreement is an expansion of an existing partnership between the two companies that began in 2021 and includes provisions that allow for extending the agreement beyond the initial four-year term. Eos and TETRA officials indicate that the agreement includes favorable pricing and cost savings allocation methodologies that motivate both parties to actively pursue further cost reductions.
