Neutral Impact 2 of 5 leadership Written later

Avantor's Board elected Simon Dingemans as a director effective January 2, 2026, filling the seat left by Jonathan Peacock's resignation effective December 31, 2025.

Written later: this filing was briefed after the fact, when past filings were added to the site, so the brief may be read with hindsight; the filing itself is the record of what was known on December 18, 2025.
