Portfolio Overview

Groupe Bruxelles Lambert’s 13F for the quarter ended 2025-12-31 reports a total reported U.S. long-equity portfolio of $364.81 million across 1 holding. The reported portfolio declined by 9.9% from $404.90 million at 2025-09-30. The filing shows no trading activity during the quarter (no new positions, no disposals, no increases or reductions) — the decline in portfolio value is therefore entirely market-driven, not the result of disposition of holdings reported on the 13F. ...

This filing may not reflect (a) non-U.S. listed securities, (b) derivatives, (c) cash, or (d) other asset classes that the filer may hold off‑report. Conclusions below refer only to the securities disclosed in this 13F.
