Pantheon Partners Participation, L.P.

The absence of any prior EDGAR filings from this manager indicates either a newly-formed entity entering the SEC filing regime at this capital level, a previously-exempt vehicle now crossing the 3C.7 threshold, or a rebranding/restructuring of an existing private equity operation; allocators should treat this as a first-institutional-visibility raise where LP due diligence cannot rely on SEC filing history.

A May 2026 amendment filing on a $602M PE fund reflects a mid-year capital deployment window when LPs are managing fiscal-year allocation schedules and Q2 fund closes; this timing also positions the vehicle to capitalize on post-election portfolio repositioning and potential exits that typically accelerate in H2.

Before committing, verify whether Kathryn Leaf's individual naming (rather than appearing only through a holding entity) creates a key-man dependency in the fund documents, and confirm whether this $602M target represents a final close number or a placeholder that may be amended upward or downward in a subsequent filing.
