Two top executives at Guidewire Software (CEO and President) sold a combined $529K in open-market sales under 10b5-1 plans within a week of the company announcing a $1.7B acquisition of Hyperexponential Ltd. The sales are small relative to the $13.1B market cap (0.004%) and were pre-planned, but the timing near a material M&A announcement warrants attention.

• President John Mullen sold 1,800 shares at $187.19 for $337K on 2026-10-26 under a 10b5-1 plan.
• Total open-market sales of $529K represent 0.004% of Guidewire's $13.1B market cap.
• The sales occurred within 6 days of Guidewire's October 27 announcement of a $1.7B cash acquisition of Hyperexponential Ltd.
