B. Riley Securities

B. Riley Securities appears on the underwriting syndicate of 62 special purpose acquisition company IPOs in our index, including OTG Acquisition Corp. I (OTGA), Quantumsphere Acquisition Corp (QUMS), Roman DBDR Acquisition Corp. II (DRDB) and Hadron Energy, Inc. (HDRN). The full list, with the role credited on each cover page, is in the mandates table on this page.

B. Riley Securities was credited as a book-running manager on 28 of its 62 SPAC mandates, 45% of them. The remainder are co-manager or syndicate positions, where the economics and the sponsor relationship sit elsewhere.

$10.9B of gross proceeds across every offering B. Riley 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: $3.2B, being the units the underwriting agreements assigned to B. Riley Securities specifically, priced at the $10 standard SPAC unit.

Skillsoft Corp. (SKIL), which raised $678M in Jun 2019. B. Riley Securities was credited as a co-manager on that offering.

32 of the SPACs B. Riley Securities underwrote closed a combination: Hadron Energy, Inc., New Horizon Aircraft Ltd., Blockchain Moon Acquisition Corp., Ocean Biomedical, Inc., Trump Media & Technology Group Corp. and Wag! Group Co.. Closing means the vehicle filed a current report reporting completion of the acquisition. That is an outcome, not a return.

10 vehicles B. Riley Securities took public are still live, either searching or working towards an announced combination: OTG Acquisition Corp. I (OTGA), Quantumsphere Acquisition Corp (QUMS), Roman DBDR Acquisition Corp. II (DRDB), Churchill Capital Corp IX/Cayman, Bayview Acquisition Corp and Aimei Health Technology Co., Ltd. (AFJK). Their combination deadlines are on each profile.

64%. Of the 50 vehicles B. Riley Securities underwrote that have already resolved, 32 closed a business combination and 18 liquidated. The market-wide figure is 59.5%, so B. Riley Securities 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.

Measured against the $10.00 the units were sold at, the only baseline every SPAC shares, the strongest of B. Riley Securities's closed deals currently is Oklo Inc. (OKLO) at $28 a share, ahead of GPGI, Inc. and Aeva Technologies, 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.

Churchill Capital (6 deals), B. Riley Principal Sponsor Co (2 deals), Roman DBDR (1 deal), Aesther Healthcare (1 deal) and Mehana (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 Chardan (16), EF Hutton (9), Citigroup (8), I-Bankers Securities (5) and EarlyBirdCapital (5). 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 Oct 14, 2015 and the most recent Sep 12, 2025. 10 of its vehicles are still live, so the franchise is active.

2021, with 24 mandates worth $4.4B 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.

The average offering it has been named on raised $176M, against a range from $729K to $678M. 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.

Technology (23), Financial Services (16), Generalist (12), Media & Entertainment (8) and Healthcare (6). 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 (12), NYSE (5) and OTC (3). Listing venue is taken from the exchange record on the registrant's SEC profile.

18. 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.

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.
