WILLIAM BLAIR INVESTMENT MANAGEMENT, LLC
CIK 00016449563 SPACs with a current declared position, filed between May 7, 2021 and Feb 10, 2022. 0 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.
This filer has not filed a Schedule 13 on any SPAC since Feb 10, 2022. Read the page below as a record of what was declared, not as a register of what is held.

3 superseded statements
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.

Appears alongside
other filers with a current declared position in the same SPACsCo-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.
