Coller International Partners IX - B, L.P.

The absence of prior EDGAR filings from Coller despite operating a multi-vintage series suggests this manager either operates primarily outside U.S. regulatory oversight or has historically not registered vehicles on EDGAR, making this 2026 filing an anomaly that warrants clarification on whether the manager is shifting toward more U.S. LP capital or this vintage alone targets Rule 506(b) investors.

Filing in May 2026 aligns with LP capital deployment cycles and year-end budget allocation windows for institutional investors, positioning the fund to capitalize on mid-year commitment periods when allocators finalize their PE allocations before year-end; however, mid-vintage timing also suggests this B-tranche is likely a follow-on raise after the main IX fund achieved initial close.

Verify whether the two named GPs (Jeremy Coller and Cyril Mahon) have defined key-person provisions and co-investment obligations, and confirm the total GP count of 12 includes operating partners or is weighted toward deal execution rather than fundraising — this composition determines whether concentration risk exists if either named GP departs.
