Analyst questions

R. Seelaus & and SPACs, answered

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

Which SPACs has R. Seelaus & underwritten?

R. Seelaus & appears on the underwriting syndicate of 8 special purpose acquisition company IPOs in our index, including Belong Acquisition Corp., Sandbridge X2 Corp, Fast Radius, Inc. and Climate Real Impact Solutions II Acquisition 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 R. Seelaus & book-run?

We have not indexed a book-running credit for R. Seelaus &; 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.

How much SPAC capital has R. Seelaus & underwritten?

$2.1B of gross proceeds across every offering R. Seelaus & 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: $32.3M, being the units the underwriting agreements assigned to R. Seelaus & specifically, priced at the $10 standard SPAC unit.

What is the largest SPAC IPO R. Seelaus & has worked on?

AEA-Bridges Impact Corp., which raised $401M in Oct 2020. R. Seelaus & was credited as a syndicate member on that offering.

Which R. Seelaus & SPACs completed a business combination?

5 of the SPACs R. Seelaus & underwrote closed a combination: Fast Radius, Inc., Queen's Gambit Growth Capital, AEA-Bridges Impact Corp., EVgo Inc. and Owlet, Inc.. Closing means the vehicle filed a current report reporting completion of the acquisition. That is an outcome, not a return.

Which R. Seelaus & SPACs are still looking for a target?

R. Seelaus & has no live SPAC mandates in our index; every vehicle it underwrote has either closed a deal or wound up.

What is R. Seelaus &'s SPAC completion rate?

62.5%. Of the 8 vehicles R. Seelaus & underwrote that have already resolved, 5 closed a business combination and 3 liquidated. The market-wide figure is 59.5%, so R. Seelaus & sits above 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 R. Seelaus & SPAC performed best after its merger?

Measured against the $10.00 the units were sold at, the only baseline every SPAC shares, the strongest of R. Seelaus &'s closed deals currently is Owlet, Inc. (OWLT) at $4 a share, ahead of EVgo Inc.. Treat that as a snapshot, not a return: it ignores dividends, splits, warrant exercise and anything that happened in between, because historical price series are not part of our data. For a proper total-return comparison use your market-data provider with the post-merger tickers.

Which sponsors does R. Seelaus & work with most?

AEA-Bridges Impact (1 deal), Belong (1 deal), Climate Change Crisis Real Impact (1 deal), Climate Real Impact Solutions (1 deal) and ENNV (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 R. Seelaus & share SPAC syndicates with?

Most often Siebert Williams Shank (7), Academy Securities (5), Drexel Hamilton (5), Roberts & Ryan (4) and Citigroup (4). 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 R. Seelaus & start underwriting SPACs, and is it still active?

Its first SPAC IPO in our index priced Sep 16, 2020 and the most recent Jul 26, 2021. It has no live vehicles at present.

What was R. Seelaus &'s busiest year in SPACs?

2021, with 5 mandates worth $1.2B 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 R. Seelaus & typically underwrite?

The average offering it has been named on raised $257M, against a range from $41.2M to $401M. 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 R. Seelaus &'s SPACs target?

Consumer (2), Energy (2), Technology (1), Energy Transition (1) and 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.

Where do R. Seelaus &'s SPACs list?

Nasdaq (1) and NYSE (1). Listing venue is taken from the exchange record on the registrant's SEC profile.

How many of R. Seelaus &'s SPACs liquidated?

3. 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 R. Seelaus & 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 R. Seelaus & itself.

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.
