This record draws on an unusually large number of source documents: a form of unknown type published July 11, 2025; an 8-K published May 29, 2025; a document of unknown form published May 29, 2025; two separate 8-K filings with Exhibit 99.1, both published May 29, 2025; an 8-K/A with Exhibit 99.2, published August 12, 2025; an 8-K with Exhibit 2.1, published May 29, 2025; an 8-K published August 11, 2025; and another document of unknown form published May 29, 2025, all filed with the SEC via EDGAR. This volume of filings, spanning the signing in May 2025 through amendments in July and August 2025, reflects the multiple disclosure steps typical of a signed-to-closed merger process. The deal's current status is closed.

Financial advisory roles are clearly delineated by side, with both advisors serving in a lead capacity (reflected across duplicate entries in the facts block). Pickering Energy Partners is acting as financial advisor to Heliogen, the target, per the statement "Pickering Energy Partners is acting as financial advisor and Cooley LLP is acting as legal counsel to Heliogen." On the acquirer side, Piper Sandler & Co. is acting as financial advisor to Zeo, consistent with the language "Piper Sandler & Co. is acting as financial advisor and Ellenoff Grossman & Schole LLP is acting as legal counsel to Zeo."

Legal advisors are disclosed for both sides: Cooley LLP is acting as legal counsel to Heliogen, the target, while Ellenoff Grossman & Schole LLP is acting as legal counsel to Zeo, the acquirer.

Beyond the classification of this transaction as a stock-for-stock, reverse triangular merger with a disclosed value of $10,000,000, no further detail on the specific exchange ratio or other consideration terms is included in the facts provided.

The one notable gap in this record is the specific stock exchange ratio used in the merger, which is not given in the facts provided; otherwise, this record is comparatively well-documented, with the deal's closed status and a substantial set of source filings tracking the transaction from signing through closing.
