Executive Summary
Founder and 10% stockholder David A. Duffield filed a Form 144 notice of intent to sell 107,500 shares of Workday common stock, with an estimated aggregate market value of approximately $14.0 million. The sale is marked as being made pursuant to a Rule 10b5-1 trading plan, and the filing shows a consistent pattern of monthly 107,500-share sales under the same plan since March 2026.
