Actionable Insight • Neutral

Monitor the outcome of the November 18 annual meeting, particularly the director election results, given the activist context from the recent SC 13D/A filing. The Gebbia family's 40.4% control block makes a dissident victory unlikely unless significant institutional support materializes.
