What changed: Heliogen, Inc., the successor to Athena Technology Acquisition Corp., filed a merger proxy dated July 11, 2025 for a special meeting held virtually on August 8, 2025 at 6 a.m. Pacific Time, record date June 30, 2025, to adopt an Agreement and Plan of Merger and Reorganization dated May 28, 2025 under which Zeo Energy Corp. acquires Heliogen through Hyperion Merger Corp. and Hyperion Acquisition LLC. Heliogen's redeemable warrants are exercisable to purchase one share at $402.50 per share and trade over the counter under HLGNW, having moved off the NYSE on November 8, 2023. Why it matters: A warrant exercise price of $402.50 a share is the arithmetic scar of successive reverse splits - the original $11.50 SPAC warrants adjusted upward by a factor of thirty-five, leaving them permanently worthless. Heliogen was delisted from the NYSE to the over-the-counter market in November 2023 and is now being absorbed by Zeo Energy, itself a de-SPAC successor. The Athena trust was released years before, so holders exit on merger terms rather than at any floor.

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.
