News on RIDGEFIELD ACQUISITION CORP

Last 90 days

Nothing in the last 90 days that names this vehicle. We attribute a story only when the release carries the ticker or the registered name, so an empty section means no press release or wire story matched — not that nothing was published. The filings below are the primary record either way.

RIDGEFIELD ACQUISITION CORP: questions answered

What is RIDGEFIELD ACQUISITION CORP (RDGA)?

RIDGEFIELD ACQUISITION CORP is a special purpose acquisition company incorporated in Colorado and registered with the SEC under CIK 0000812152. Class A shares trade under the ticker RDGA. The vehicle is sponsored by RIDGEFIELD. Business combination closed; the company trades under a new ticker.

How much does RIDGEFIELD ACQUISITION CORP hold in trust?

No trust balance has been disclosed in a filing we have indexed for RIDGEFIELD ACQUISITION CORP. For a newly priced IPO this is normal: the figure first appears in the quarterly report after closing.

When must RIDGEFIELD ACQUISITION CORP 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 RIDGEFIELD ACQUISITION CORP 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 RIDGEFIELD ACQUISITION CORP, 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. 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 RIDGEFIELD ACQUISITION CORP trade under?

Class A shares trade as RDGA. 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 RIDGEFIELD ACQUISITION CORP?

No. Trust per share is a disclosed, contractual figure: what a redeeming holder receives. The market price is whatever the shares change hands at, which can sit above the trust when a deal is well received or below it when the market doubts one will close. We do not have a current quote for this vehicle, so no spread is shown.

Who sponsors RIDGEFIELD ACQUISITION CORP, and what is their track record?

RIDGEFIELD is the sponsor entity, part of the RIDGEFIELD franchise. This is the only vehicle we have attributed to that sponsor.

Is RIDGEFIELD ACQUISITION CORP tradeable, and where?

Our market-data provider returns no quote for RDGA. That is normal for a vehicle that has not begun trading, has been delisted after a wind-up, or is too thinly traded to carry a two-sided market. The absence of a quote is shown as "not quoted" rather than as a zero.

Is RIDGEFIELD ACQUISITION CORP a good investment?

That is not a question this site answers. RIDGEFIELD ACQUISITION CORP 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 RIDGEFIELD ACQUISITION CORP data come from?

Filings RIDGEFIELD ACQUISITION CORP submitted to the SEC under CIK 0000812152: 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 19, 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.
