SPAC Advisory Partners

SPAC Advisory Partners appears on the underwriting syndicate of 2 special purpose acquisition company IPOs in our index, including Quantumsphere Acquisition Corp (QUMS) and Quartzsea Acquisition Corp (QSEA). The full list, with the role credited on each cover page, is in the mandates table on this page.

We have not indexed a book-running credit for SPAC Advisory Partners; every mandate on record is a co-manager or syndicate position. Bookrunner status is read from the prospectus cover, so a blank can also mean the cover did not separate the roles.

$165.6M of gross proceeds across every offering SPAC Advisory Partners 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: $143.5M, being the units the underwriting agreements assigned to SPAC Advisory Partners specifically, priced at the $10 standard SPAC unit.

Quantumsphere Acquisition Corp (QUMS), which raised $82.8M in Aug 2025. SPAC Advisory Partners was credited as a syndicate member on that offering.

None of the SPACs SPAC Advisory Partners underwrote has yet reported a completed business combination in the filings we index. 2 remain live and 0 returned their trust.

2 vehicles SPAC Advisory Partners took public are still live, either searching or working towards an announced combination: Quantumsphere Acquisition Corp (QUMS) and Quartzsea Acquisition Corp (QSEA). Their combination deadlines are on each profile.

None of SPAC Advisory Partners's SPAC mandates has resolved yet, so a completion rate would be meaningless. It is left blank rather than shown as zero.

We hold a current quote for none of SPAC Advisory Partners'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.

Blue Jay (1 deal) and Whiteowl (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.

Most often EF Hutton (2) and B. Riley Securities (1). 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.

Its first SPAC IPO in our index priced Mar 19, 2025 and the most recent Aug 7, 2025. 2 of its vehicles are still live, so the franchise is active.

The average offering it has been named on raised $82.8M, against a range from $82.8M to $82.8M. 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.

Generalist (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.

Nasdaq (2). Listing venue is taken from the exchange record on the registrant's SEC profile.

None in our index. Either its vehicles closed a deal or they are still inside their combination window.

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 SPAC Advisory Partners itself.
