This order has no immediate material impact on Danaher's business or stock. The preliminary injunction remains in effect, but the underlying noncompete dispute proceeds to trial in November 2026. Watch for any subsequent rulings on the merits or settlement developments; neither the competitive risk of Stumpe joining Siemens nor the legal costs of litigation are material to a $140B enterprise.

Executive Summary
The Delaware Court of Chancery denied Martin Stumpe's motion to certify an interlocutory appeal of the May 29, 2026 ruling that (a) denied his motion to dismiss for lack of personal jurisdiction and improper venue, and (b) granted Danaher a preliminary injunction barring Stumpe from starting work as Siemens' Chief Technology Officer on June 1, 2026. This procedural ruling keeps the preliminary injunction in place, preserves the status quo through the November 2026 expedited trial, and confirms the court's jurisdiction over the noncompete dispute. For a $140B company, this is a modest litigation-procedural win — the core legal question (enforceability of the noncompete under Washington law) remains for trial.
Court Ruling Details
Key Facts
- Danaher sued former Chief Data and AI Officer Martin Stumpe to enforce a 12-month noncompete after he accepted CTO role at Siemens Medical Solutions.
- Court denied Stumpe's motion to dismiss for lack of personal jurisdiction and improper venue on May 29, 2026.
- Court granted Danaher's motion for a preliminary injunction barring Stumpe from starting at Siemens on June 1, 2026.
- Stumpe sought certification of interlocutory appeal under Supreme Court Rule 42; this order DENIES that application.
- Expedited trial is scheduled for November 2026.
- The ruling is a procedural denial of interlocutory appeal — the merits of the noncompete's enforceability under Washington law have not been finally resolved.
Financial Impact
No financial damages awarded. The ruling is procedural and does not quantify any monetary exposure.
Risk Factors
- If the November 2026 trial or a later appeal eventually invalidates the noncompete, Stumpe could join Siemens — a direct competitor — which may have intangible competitive implications.
- Washington law (RCW § 49.62.050) issues remain unresolved and could limit the enforceability of noncompetes for Washington-based employees, setting a precedent for Danaher's future workforce restrictions.
