Analyst questions

US Tiger Securities and SPACs, answered

The questions a desk actually asks about a bank's blank-check franchise, answered from US Tiger Securities's own mandates rather than from generic explainer copy.

Which SPACs has US Tiger Securities underwritten?

US Tiger Securities appears on the underwriting syndicate of 14 special purpose acquisition company IPOs in our index, including Embrace Change Acquisition Corp. (EMCGF), Mobiv Acquisition Corp, Acri Capital Acquisition Corp and Prime Number Acquisition I Corp.. The full list, with the role credited on each cover page, is in the mandates table on this page.

How many SPAC IPOs has US Tiger Securities book-run?

US Tiger Securities was credited as a book-running manager on 2 of its 14 SPAC mandates, 14% of them. The remainder are co-manager or syndicate positions, where the economics and the sponsor relationship sit elsewhere.

How much SPAC capital has US Tiger Securities underwritten?

$1.1B of gross proceeds across every offering US Tiger Securities was named on. That is the conventional league-table measure, which credits the full deal to each syndicate member. The narrower figure is its own allocation: $430.5M, being the units the underwriting agreements assigned to US Tiger Securities specifically, priced at the $10 standard SPAC unit.

What is the largest SPAC IPO US Tiger Securities has worked on?

Evergreen Corp, which raised $116.7M in Feb 2022. US Tiger Securities was credited as a syndicate member on that offering.

Which US Tiger Securities SPACs completed a business combination?

1 of the SPACs US Tiger Securities underwrote closed a combination: Maxpro Capital Acquisition Corp.. Closing means the vehicle filed a current report reporting completion of the acquisition. That is an outcome, not a return.

Which US Tiger Securities SPACs are still looking for a target?

1 vehicles US Tiger Securities took public are still live, either searching or working towards an announced combination: DUET Acquisition Corp.. Their combination deadlines are on each profile.

What is US Tiger Securities's SPAC completion rate?

7.7%. Of the 13 vehicles US Tiger Securities underwrote that have already resolved, 1 closed a business combination and 12 liquidated. The market-wide figure is 13.2%, so US Tiger Securities sits below it. SPACs still searching are excluded, because an unfinished clock is not a result. The rate measures the vehicles, not the bank: a syndicate has no control over whether a sponsor finds a target.

Which US Tiger Securities SPAC performed best after its merger?

We hold a current quote for none of US Tiger Securities's closed deals, so no comparison is possible here. Post-merger price history is not part of our dataset, and we would rather say so than imply a ranking the data does not support. What this page does show is the outcome of every vehicle and the trust economics disclosed at the time.

Which sponsors does US Tiger Securities work with most?

Aetherium (1 deal), DUET (1 deal), Evergreen (1 deal), Genesis Unicorn (1 deal) and HHG (1 deal). Sponsor franchises are resolved from the sponsor entity named in each prospectus, so repeat issuers group together even though every vehicle is a separate legal entity.

Which banks does US Tiger Securities share SPAC syndicates with?

Most often EF Hutton (12), Joseph Gunnar & (11), Tiger Brokers (NZ) (8), Ingalls & Snyder (3) and Brookline (2). Syndicate composition is read from the prospectus cover and the underwriting section, so these are co-appearances on the same offering, not a commercial relationship we have any other visibility into.

When did US Tiger Securities start underwriting SPACs, and is it still active?

Its first SPAC IPO in our index priced Sep 21, 2021 and the most recent Aug 11, 2022. 1 of its vehicles are still live, so the franchise is active.

What was US Tiger Securities's busiest year in SPACs?

2022, with 8 mandates worth $545.1M of gross proceeds. The chart on this page shows the full year-by-year run, which for most houses traces the 2020-21 boom and the retreat that followed.

What size of SPAC does US Tiger Securities typically underwrite?

The average offering it has been named on raised $81.4M, against a range from $19.6M to $116.7M. Deal size is a reasonable proxy for where a house sits in the market: the bulge bracket concentrates on larger trusts, the SPAC specialists on smaller ones.

Which sectors do US Tiger Securities's SPACs target?

Technology (9), Generalist (3), Consumer (2), Healthcare (2) and Energy Transition (1). Mandates are read from charter language in the prospectus and are often deliberately broad. Many SPACs reserve the right to pursue any industry, in which case no sector is tagged at all.

How many of US Tiger Securities's SPACs liquidated?

12. A liquidation means the vehicle reached its combination deadline without closing a deal and returned the trust to public shareholders. That is the mechanism working as designed, not a default. Holders who did not redeem got their pro-rata share of the trust back.

Where does this US Tiger Securities data come from?

Every figure is read from filings the registrants made with the SEC. Syndicate membership and role come from the prospectus cover and the underwriting section of each IPO prospectus (Form 424B4); outcomes come from the filing record: a current report announcing completion, or a delisting notice ending a liquidation. Nothing here is sourced from press coverage or from US Tiger Securities itself.

Compiled by the SPACListing research desk

Last reconciled Aug 12, 2026

Every figure on this page is read from documents the registrants filed with the U.S. Securities and Exchange Commission, principally IPO prospectuses (Form 424B4), current reports (Form 8-K), delisting notices (Form 25-NSE). 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.
