Reading the filings
Arithmetic on what Siddhi Acquisition Corp (Cayman Islands) 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.
Trading at a discount to trust
At $10.53 the shares sit within a point of the $10.55 redemption value, so the market is pricing the cash and little else.
Trust versus the $10 unit
The trust holds $10.55 per public share, 5.5% above the $10.00 the units were sold at. That spread is accrued interest on the trust and, where the charter provides for it, sponsor contributions paid in to buy more time. It is the floor a public shareholder can redeem at, not a valuation of the business.
Time on the clock
120 days to the Jan 2, 2027 deadline. Still workable for a deal already in diligence, tight for one that has not been found. Watch for an extension proxy, which typically appears a month or two before the date.
Sponsor record
Siddhi has launched 2 vehicles, none of which has resolved yet, so there is no completion record to read.
Underwriting
Santander led the offering. It has been named on 18 SPAC IPOs, book-running 15 of them, and 0% 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.

Attention is not quality. FOMO rises on news volume and on the market paying above trust, both of which have preceded plenty of disappointments.

searching
Potential is about execution, not about the target. It says nothing about whether the eventual deal is worth owning, because the target is usually unknown when the score is computed.
These are derived measures, not ratings of investment merit. They carry no view on the target, no price target and no recommendation, and a high score is not a reason to buy anything.

Siddhi Acquisition Corp (Cayman Islands): questions answered
What is Siddhi Acquisition Corp (Cayman Islands) (SDHI)?
Siddhi Acquisition Corp (Cayman Islands) is a special purpose acquisition company incorporated in Cayman Islands and registered with the SEC under CIK 0002034037. It completed its initial public offering in Apr 2025, raising $276.0M in gross proceeds and listing on Nasdaq. Class A shares trade under the ticker SDHI, units under SDHIU, rights under SDHIR on Nasdaq. The vehicle is sponsored by Siddhi through Siddhi Sponsor LLC. The mandate targets generalist. IPO closed, trust funded, no definitive agreement announced.
How much does Siddhi Acquisition Corp (Cayman Islands) hold in trust?
Approximately $291,120,263, or about $10.55 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 Siddhi Acquisition Corp (Cayman Islands) complete a merger?
By Jan 2, 2027. If no combination closes by then the sponsor must seek a further extension or wind the vehicle up and return the trust.
What happens if Siddhi Acquisition Corp (Cayman Islands) 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 Siddhi Acquisition Corp (Cayman Islands), 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 $10.55 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 Siddhi Acquisition Corp (Cayman Islands) trade under?
Class A shares trade as SDHI on Nasdaq, the units as SDHIU, with rights as SDHIR. 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 Siddhi Acquisition Corp (Cayman Islands)?
No, and the gap between them is the whole trade. Trust per share is a disclosed, contractual figure of $10.55, being what a redeeming holder receives. The market price is whatever the shares change hands at: most recently $10.53, a discount of 0.19% to the redemption value. Quotes on this site are delayed and indicative; confirm on your own venue before trading.
Who sponsors Siddhi Acquisition Corp (Cayman Islands), and what is their track record?
Siddhi Sponsor LLC is the sponsor entity, part of the Siddhi franchise. That franchise has launched 2 vehicles in total, none of which has resolved yet. Named principals: Brian Finn, Sam Potter.
Which banks underwrote the Siddhi Acquisition Corp (Cayman Islands) IPO?
Santander. Santander was credited as book-running manager on the cover. Syndicate membership and role are read from the prospectus cover and the underwriting section.
Is Siddhi Acquisition Corp (Cayman Islands) tradeable, and where?
Yes. SDHI returned a live quote of $10.53 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 Siddhi Acquisition Corp (Cayman Islands) a good investment?
That is not a question this site answers. Siddhi Acquisition Corp (Cayman Islands) 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 Siddhi Acquisition Corp (Cayman Islands) data come from?
Filings Siddhi Acquisition Corp (Cayman Islands) submitted to the SEC under CIK 0002034037: 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.

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.
