What the evidence supports
Eos Energy Enterprises told the SEC (Form 8-K, Item 2.03) that it entered into a financing arrangement or sold its securities. The filing gives Sep 10, 2026 as the date of the earliest event reported. The company also furnished a press release, which is its own account rather than a regulatory statement.
What remains unknown
How much money will actually be raised or drawn, at what final price, and how it will be used beyond what the company stated. Stated amounts can be maximums or targets rather than money already received.
