Guidewire's CEO Sold $166,000 in Stock — Here's What Investors Should Know

Guidewire Software CEO Michael George Rosenbaum sold 1,200 shares worth $166,164 on July 13, 2026, under a pre-established Rule 10b5-1 trading plan adopted in October 2025. The sale reduced his direct holdings by only 0.61%, and he continues to hold approximately 195,000 shares valued at $27.36 million. The transaction represents routine liquidity management and does not signal concerns about the business, as Rosenbaum has been making similar small weekly sales. Despite a 37% stock decline over the past year, Guidewire reported strong Q3 performance with 27% revenue growth and 19% ARR growth, with management expecting a record Q4.
