Summary
Westlake secured dismissals of two ethylene antitrust lawsuits in Amsterdam District Court on July 29, 2026. The larger case, filed by Shell Chemical Europe in March 2023, had sought an undisclosed amount €1,025 million in damages plus statutory interest. The second case, filed by Stichting Ethylene Claims in November 2023, sought a declaratory judgment establishing liability for unspecified damages.
Both plaintiffs may appeal the dismissals. The favorable rulings reduce Westlake's immediate litigation exposure but do not resolve the broader antitrust matter. Twelve related lawsuits remain pending at first instance courts in the Netherlands and Germany.
The dismissals suggest the plaintiffs' claims may face evidentiary or procedural hurdles, but the outcome of the remaining cases and any appeals will determine Westlake's ultimate liability. Investors should monitor whether the dismissed plaintiffs appeal and how the trial courts handling the twelve pending cases respond to similar claims.
