Overview
Eos Energy Enterprises, Inc. is a special purpose acquisition company incorporated in Delaware and registered with the SEC under CIK 0001805077. It completed its initial public offering in May 2020, raising $175M in gross proceeds and listing on Nasdaq. Class A shares trade under the ticker EOSE, warrants under EOSEW on Nasdaq. The vehicle is sponsored by B. Riley Principal Sponsor Co through B. Riley Principal Sponsor Co. II, LLC. Business combination closed; the company trades under a new ticker.
“we intend to focus on established businesses that have an aggregate enterprise value of approximately $400 million to $1 billion and would benefit from access to public markets and the operational and strategic expertise of our management team and board of directors.”
Reading the filings
Arithmetic on what Eos Energy Enterprises, Inc. has disclosed, written the way a desk would read it. These are observations, not a rating. Nothing here scores the vehicle or implies a view on it.
Trust versus the $10 unit
The trust holds $10.00 per public share, effectively the $10.00 the units were sold at, so little or no interest has accrued to the account yet.
Warrant coverage
Each unit carried one-half warrant per unit. Warrants are dilution deferred: they cost the holder nothing until exercised, and they overhang the post-combination share count. Thinner coverage is generally a sign of a stronger book at pricing.
Sponsor record
B. Riley Principal Sponsor Co has launched 3 vehicles. Of the 3 that have resolved, 3 closed a combination and 0 liquidated, a 100% completion rate. A sponsor's record is not a forecast, but it does tell you whether the team has taken a deal across the line before.
Underwriting
B. Riley Securities led the offering. It has been named on 62 SPAC IPOs, book-running 28 of them, and 64% of its resolved vehicles closed a deal. The syndicate has no control over whether a sponsor finds a target, but the quality of the book at pricing shapes who ends up holding the units.
Filings per month since the first one. A vehicle that has gone quiet with a deadline ahead is a different proposition from one that is still working.
787 filings in all. 36 in the last three months, against a busiest month of 40.

Eos Energy Enterprises, Inc.: questions answered
What is Eos Energy Enterprises, Inc. (EOSE)?
Eos Energy Enterprises, Inc. is a special purpose acquisition company incorporated in Delaware and registered with the SEC under CIK 0001805077. It completed its initial public offering in May 2020, raising $175M in gross proceeds and listing on Nasdaq. Class A shares trade under the ticker EOSE, warrants under EOSEW on Nasdaq. The vehicle is sponsored by B. Riley Principal Sponsor Co through B. Riley Principal Sponsor Co. II, LLC. Business combination closed; the company trades under a new ticker.
How much does Eos Energy Enterprises, Inc. hold in trust?
Approximately $176,777,682, or about $10.00 per public share, as at the most recent filing on record. Trust balances move: shareholders redeem at extension votes and at the combination vote, and sponsors pay contributions in to extend. Treat the figure as a point-in-time disclosure, not a running balance.
When must Eos Energy Enterprises, Inc. complete a merger?
No combination deadline appears in the filings we have indexed. The date is stated in the charter and repeated in each quarterly report; where our parser could not establish it with confidence we leave it blank rather than infer one.
What happens if Eos Energy Enterprises, Inc. does not find a target in time?
The charter requires the vehicle to redeem 100% of the public shares and return the trust, pro rata, to public shareholders. That is the mechanism working as designed rather than a default. Founder shares and warrants are worthless in that outcome, which is why the sponsor's incentive is to get a deal done or to buy more time. Across the market, deadline lapsed without a deal; trust returned to public shareholders.
Can I redeem shares in Eos Energy Enterprises, Inc., and at what price?
Public shareholders may elect to redeem in connection with a combination vote and at each extension vote, at the pro-rata trust value on the relevant record date, most recently disclosed at about $10.00 per share. Redemption is a right attached to the public shares only; warrants and rights carry no claim on the trust. The mechanics and the deadline for electing are set out in the proxy statement for the vote in question.
What tickers does Eos Energy Enterprises, Inc. trade under?
Class A shares trade as EOSE on Nasdaq, and the warrants as EOSEW. Units trade first and separate into their component securities roughly 52 days after the IPO; only the Class A shares carry the redemption right against the trust.
Is the trust value the same as the share price for Eos Energy Enterprises, Inc.?
No, and the gap between them is the whole trade. Trust per share is a disclosed, contractual figure of $10.00, being what a redeeming holder receives. The market price is whatever the shares change hands at: most recently $1.74, a spread to the redemption value. Quotes on this site are delayed and indicative; confirm on your own venue before trading.
How much dilution do Eos Energy Enterprises, Inc.'s founder shares and warrants create?
Each unit also carried one-half warrant per unit, which is dilution deferred until exercise. Both are disclosed in the prospectus and both survive into the combined company, which is why a de-SPAC at $10 is not economically the same as an IPO at $10.
Who sponsors Eos Energy Enterprises, Inc., and what is their track record?
B. Riley Principal Sponsor Co. II, LLC is the sponsor entity, part of the B. Riley Principal Sponsor Co franchise. That franchise has launched 3 vehicles in total, of which 3 closed a combination and 0 liquidated, a 100% completion rate on resolved vehicles. Named principals: Bryant Riley, Daniel Shribman, Kenneth Young.
Which banks underwrote the Eos Energy Enterprises, Inc. IPO?
B. Riley Securities. B. Riley Securities was credited as book-running manager on the cover. Syndicate membership and role are read from the prospectus cover and the underwriting section.
Is Eos Energy Enterprises, Inc. tradeable, and where?
Yes. EOSE returned a live quote of $1.74 on Nasdaq. Quotes here are delayed and refreshed on a schedule rather than streamed, so treat the figure as indicative and confirm on your own venue. Units and warrants trade under their own symbols and are quoted separately.
Is Eos Energy Enterprises, Inc. a good investment?
That is not a question this site answers. Eos Energy Enterprises, Inc. is covered here as reference data: what the company filed, when it filed it, and what the numbers in those filings say. The Edge, FOMO and Potential scores on this page are derived measures with a published formula, not ratings of investment merit: they describe the setup, and every component is shown so you can take them apart. We publish no price targets and no recommendations, and nothing here should be read as advice. The figures are a starting point for your own work, and each one carries the accession number of the filing it came from.
Where does this Eos Energy Enterprises, Inc. data come from?
Filings Eos Energy Enterprises, Inc. submitted to the SEC under CIK 0001805077: the registration statement and final prospectus for the structure, quarterly and annual reports for the trust, current reports and proxy statements for deals, votes and extensions. Trust economics are taken from the registrant's own XBRL tags rather than parsed from prose, which is why they are exact. Every filing in the history above is listed with its accession number, which identifies the document uniquely on EDGAR; Pro accounts open it directly from the row.
Compiled by the SPACListing research desk
Last reconciled Oct 20, 2026
Every figure on this page is read from documents the registrants filed with the U.S. Securities and Exchange Commission, principally the IPO prospectus (Form 424B4), quarterly and annual reports, current reports and proxy statements, the registrant's own XBRL tags for trust economics. Nothing is sourced from press coverage, from the companies themselves, or from a third-party aggregator. Where a filing does not disclose something, the field is left blank rather than estimated.
