Sonos (SONO) Director Karen Boone Exercises Options, Sells Shares

What Happened

• Karen Boone, a Sonos director, exercised 31,766 stock options on Sept 25, 2026 (exercise price $13.56/share; total exercise cost $430,747) and sold shares the same day. She sold 31,766 shares at a weighted average price of $18.12 ($575,724) and an additional 15,000 shares at a weighted average price of $18.13 ($271,913), for total gross proceeds of $847,637.

• The filing shows an option exercise immediately followed by sales of the resulting shares on the same date, which is common when insiders use exercised shares to cover costs or diversify; this is a disposition, not a new purchase signal.
• Transactions were reported under a prearranged 10b5-1 plan, which often governs timing of insider sales to avoid questions about trading on material nonpublic information.
• The filing appears timely under Form 4 rules (filed within the required business-day window).
