Zeidel Darren, General Counsel at Aon plc (NYSE: AON), has demonstrated a consistent pattern of selling activity with no recorded purchases, according to SEC Form 4 filings. Over 29 reported transactions, all were dispositions, totaling approximately $10.9 million in aggregate value. The sales have been concentrated in Aon stock, with notable transactions occurring in 2025 and 2026. On February 17, 2026, Zeidel sold shares worth $1.64 million, followed by another $1.42 million disposition on February 26, 2026. Earlier, on November 5, 2025, he executed two sales totaling over $3 million, including a single transaction valued at $2.61 million. Smaller but recurring sales, such as those on July 28, 2026, for $180,500, $274,050, and $263,200, suggest a methodical reduction in holdings.
The filings also indicate derivative transactions, primarily involving stock awards ("F" codes) and option exercises ("M" codes), though these did not result in monetary gains. For example, on February 13, 2026, Zeidel reported awards and option transactions with no associated dollar values, while earlier filings in 2024 and 2025 show similar activity. The absence of any buy transactions and the repeated sales—particularly the multi-million-dollar disposals—highlight a clear divestment trend. While the reasons for these sales are not disclosed, the data reflects a sustained reduction in Zeidel’s Aon equity position over time.
