SPAC-arb rosterCIK 0001257391

7 SPACs with a current declared position, filed between Feb 14, 2022 and Apr 22, 2026. 2 of them were re-affirmed in the last 12 months. The rest are the filer’s last word on a position, not proof it is still held: an amendment is only required on a material change, so a fund that sells below 5% may never file again.

12 superseded statements (newest 10 shown)

An amendment replaces a stake as current; it never erases the record of it. These are the earlier statements, each with the accession that replaced it — kept because “what did this filer say in 2022” is a different question from “what does it say now”, and only the second one has an answer above.

Reporting persons on this filer's schedules

one filer, several names — collapsed once, shown in full

A joint Schedule 13 names every person who beneficially owns the shares — the management company, the funds it advises, the general partner and often the individual who controls all three. They report the same shares. Counting them separately would publish this filer’s footprint two or three times over, so they are counted once, under CIK 0001257391. This filer has named 2 of them across the schedules in the table above:

  • WBox 2015-5
  • Whitebox Advisors

Appears alongside

other filers with a current declared position in the same SPACs

Co-occurrence in the disclosure record, and nothing more. It is not evidence of a group, an agreement or acting in concert — filers who act as a group say so on the cover page and file a 13D. Two arbitrage funds above 5% in the same shell is the ordinary shape of this market. The second number restricts both sides to statements filed in the last 12 months, because a 2021 stake beside a 2026 one is two facts about two different years.

Every percentage above is the one printed on the cover page of the filing cited beside it — a percentage of the shares outstanding on that date. A SPAC’s float collapses at each redemption, so two of these percentages are percentages of two different companies and they do not add. Rows are one per SPAC: where a joint schedule names several reporting persons, the largest single figure is shown rather than their sum, because a manager and the funds it advises beneficially own the same shares. Nothing on this page is derived from a 13F, a vendor holdings file or a press release. See how this is built.
