Eos Energy Enterprises Secures New Supply Agreement and Reports First-Quarter Results

Eos Energy Enterprises Inc. entered into a material definitive supply agreement while reporting first-quarter 2026 financial results, the company disclosed in a Form 8-K filed with the SEC on May 13, 2026.

The filing covers Item 1.01 Entry into a material definitive agreement, Item 2.02 Results of operations and financial condition, Item 3.02 Unregistered sales of equity securities, Item 7.01 Regulation FD disclosure and Item 9.01 Financial statements and exhibits.

Per the filing, the supply agreement establishes terms for component delivery to support Eos battery production at its Turtle Creek, Pennsylvania facility. The company also completed unregistered sales of equity securities under Item 3.02, generating proceeds that add to its liquidity position.

The new supply contract replaces elements of prior arrangements and takes effect immediately upon execution on or before the filing date. Operationally, the agreement secures committed volumes of key materials for the company's aqueous zinc battery systems through defined delivery milestones in 2026 and 2027.

The unregistered equity sales closed concurrently, increasing the number of outstanding shares without requiring prior registration under the Securities Act.

Downstream, the supply agreement triggers contractual delivery and payment milestones that Eos must meet to maintain favorable pricing and volume commitments. The equity sales require the company to file a Form D with the SEC within 15 days under Regulation D rules.

Financial results disclosed under Item 2.02 will be incorporated into the company's quarterly report on Form 10-Q, due in mid-June 2026, establishing the baseline for tracking progress against 2026 operating plan targets. The combined transactions extend Eos's cash runway to support continued scaling of its Gen 3 battery manufacturing line.

This marks the latest in a series of supply-chain and capital-market steps Eos has taken since completing its initial public listing in 2020 via SPAC. The company has previously reported multiple equity sales and partnership agreements to fund commercialization of its zinc batteries for stationary energy storage applications.
