Key Considerations

1. Plan vs. Discretionary Sale: The sales were not conducted under a pre-scheduled Rule 10b5-1 trading plan. Footnote 1 notes that transactions were executed pursuant to a limit order placed during an open trading window.
2. Remaining Equity Stake: Following the sales, Mr. Troendle directly holds 433,372 shares. Additionally, he maintains indirect beneficial ownership of 4,733,019 shares through Medpace Investors, LLC, over which he holds sole voting and investment control. His post-transaction total beneficial ownership remains over 5.16 million shares, indicating significant retained alignment with the company.
3. Market Significance: Because the transactions represent discretionary, non-10b5-1 open-market sales exceeding $44 million by the chief executive, they carry high market significance.
