What changed: The filing reports a leadership transition at Eos Energy Enterprises, Inc. effective August 24, 2026: Michelle Buczkowski was appointed Chief Commercial Officer (previously Chief Administration Officer), and Nathan Kroeker will remain through October 20, 2026 to support the transition before departing. Ms. Buczkowski’s annual base salary increased from $385,000 to $440,000, and her target annual short-term incentive opportunity was increased to 100% of her annual base salary. Mr. Kroeker’s separation agreement terms have not been finalized. Why it matters: Investors should note that material terms of Mr. Kroeker’s separation agreement are pending disclosure in an amendment if entered into. The document does not contain information regarding redemption deadlines, trust value, extensions, or deal progress for B. Riley Principal Merger Corp. II, as the SPAC status is listed as LIQUIDATED.
What changed: Eos Energy Enterprises, Inc. filed as Exhibit 10.4 a Third Amendment to Loan Guarantee Agreement dated August 4, 2026 with the U.S. Department of Energy, amending the Loan Guarantee Agreement of November 26, 2024 as previously amended on March 25, 2025 and February 13, 2026 and modified by five limited consents. Why it matters: The federally guaranteed project's physical footprint is being moved — two or three of the four financed production lines relocate to a different site — and the DOE has had to consent to the borrower taking a 49% stake in a Cerberus-backed joint venture. The specific amended covenant language is in an annex not present here, so the changed terms cannot be stated from this document.
What changed: 8-K of Eos Energy Enterprises, Inc. Item 2.02 (results of operations and financial condition): on August 5, 2026 the Company issued a press release announcing its financial results for the quarter ended June 30, 2026, furnished as Exhibit 99.1. The report states the Item 2.02 information and Exhibit 99.1 are furnished and shall not be deemed filed for Section 18 purposes or incorporated by reference. Item 9.01 lists Exhibit 99.1 (press release dated August 5, 2026) and Exhibit 104 (cover page in Inline XBRL). Signed by CFO Alessandro Lagi. Why it matters: A quarterly earnings furnishing by a post-combination operating company. No figure appears in the report itself; the results are wholly in Exhibit 99.1, so this document records that Q2 2026 results were released and nothing about what they were.
What changed: Q2 2026 10-Q of Eos Energy Enterprises, Inc. (Nasdaq: EOSE), with 364,167,744 shares of common stock outstanding as of August 3, 2026; the registered warrants carry a $5.481 exercise price. The report covers the quarterly period ended June 30, 2026 and presents statements of shareholders' deficit for the three and six months then ended. Why it matters: This summary is drawn from the cover page of the report; the balance sheet and statements of operations are not covered here.
What changed: 8-K of Eos Energy Enterprises, Inc. Item 8.01 (other events): on July 23, 2026 the Company issued a press release announcing the expiration and preliminary results of its previously announced rights offering. The offering expired at 5:00 p.m. Eastern Time on July 21, 2026, and rights not exercised by that time have expired and are no longer exercisable. The press release is Exhibit 99.1 and Exhibit 104 is the Inline XBRL cover page. Signed by CFO Alessandro Lagi. Why it matters: The rights are gone and the report says so plainly, which settles the question for any holder who still held them. What it does not state is the outcome: no subscription level, no proceeds, no share count. Those are described as preliminary and sit only in Exhibit 99.1.
What changed: Eos Energy Enterprises, the B. Riley Principal Merger Corp. II successor, issued a press release on July 15, 2026 with preliminary results for the quarter ended June 30, 2026 and a business update. It expects revenue of $68 million to $69 million for the quarter, driven by a more than three-fold increase in shipments over the prior-year period, and a gross margin loss of between 69% and 73%. The second quarter marked the transition to operating two commercial production lines across two manufacturing facilities, with Battery Line 2 commencing commercial production. Why it matters: Revenue tripling on shipments is the growth case, but the margin figure is the one that decides whether it matters: a gross margin loss of 69% to 73% means the company still sells each unit for well under what it costs to build, so more volume increases the cash burn rather than reducing it. Bringing a second line into commercial production is the stated route to fixing that through scale. Until gross margin crosses zero, revenue growth at this de-SPAC translates directly into a larger financing requirement.
In plain English
Redemption deadlinethe last day to hand shares back for cash
Set by the filing that calls the meeting. Tender after it and the company is under no obligation to pay you the trust value.
Cash in trust / trust per sharethe cash the company is holding for each public share
Filed quarterly in the 10-Q's XBRL. It earns interest between filings, so the figure on a given day is slightly higher than the last filed one — where we show that we label it an estimate.
