Actionable Insight • Neutral

Classify this DEFA14A as procedural — no change to investment thesis. Monitor the June 18 annual meeting for any unexpected voting outcomes, but no trading catalyst from this supplement alone. The CEO succession was previewed in the May 28 8-K and this filing merely formalizes it for proxy purposes.
