Industry Context

StockSavvy.ai notes that insider sales, especially by founders or long-standing directors, are common for diversification or liquidity purposes, particularly when executed under a Rule 10b5-1 plan, which pre-schedules transactions to avoid accusations of trading on material non-public information. This transaction is typical for a high-net-worth individual managing their portfolio.

Comparison to Industry Standards

• StockSavvy.ai observes that the use of a Rule 10b5-1 trading plan aligns with best practices for corporate insiders to manage their equity holdings while mitigating concerns about market timing or use of non-public information.
• Many executives at comparable technology companies, such as Salesforce (CRM) or Oracle (ORCL), utilize similar plans for their stock dispositions.

Related Party Transactions

• The reported shares are held by the David A. Duffield Trust dated July 14, 1988, a revocable living trust, of which the Reporting Person is trustee and sole beneficiary.
• The sale was effected pursuant to a Rule 10b5-1 trading plan previously adopted by the David A. Duffield Trust dated December 2, 2025.

Stakeholder Impact

• Shareholders: May view the insider sale as a neutral to slightly negative signal, though the 10b5-1 plan mitigates concerns. The remaining significant holdings of Class B stock indicate continued alignment with long-term company performance.

Next Steps

• The Reporting Person undertakes to provide full information regarding the number of shares sold at each separate price within the reported ranges upon request to Workday, Inc., any security holder, or the SEC staff.

Key Dates

Recommendation

The insider sale by David A. Duffield, while substantial, was executed under a pre-arranged 10b5-1 plan, suggesting a planned liquidity event rather than a reaction to new negative information. His remaining significant holdings, particularly in Class B stock, indicate continued long-term interest in Workday's success. Therefore, this event alone does not warrant a change in investment posture; a 'hold' recommendation is appropriate, pending further fundamental analysis of the company's performance and market conditions.
