Darren Zeidel

General Counsel Darren Zeidel sold 1,950 shares totaling $725,500.00 at blended average $372.05 via 10b5-1 plan (2026-07-17).

Darren Zeidel executed 3 separate sales totaling 1,950 shares for $725,500.00, reducing his holdings by 12.7% from 15,354 shares to 13,404 shares. This transaction was part of a pre-arranged 10b5-1 trading plan, meaning the sales were scheduled and not discretionary. At AON, his prior 5 trades have shown mixed outcomes: two 30-day periods negative (−4.9% and −2.7%), two neutral-to-flat, and one strong positive (+8.6%), indicating no consistent pattern of timing accuracy at this ticker. The stock is currently at $359.33, trading 5.7% below its 52-week high of $381.00, and has posted a 13.1% gain over the past 30 days. Given that the sales were contractually scheduled rather than discretionary, this filing carries routine insider-activity significance rather than signaling any change in executive conviction about the company.

General Counsel Zeidel Darren sold 4,300 AON shares at $329.72 (2026-02-26); stock now at $337.80 amid prior weak timing pattern

Zeidel Darren, General Counsel of Aon plc, sold 4,300 shares (21.2% of pre-transaction holdings) at $329.72 on 2026-02-26, reducing his position from 20,254 to 15,954 shares. The transaction value was $1,417,783.53. The stock has since risen to $337.80, placing the sale about 8 points below current price, but still within the 52-week range and -17.5% from the 52-week high of $409.32. His prior four sells at Aon show mixed outcomes: three measurable 90-day periods had positive returns (+0.7%, +0.5%, +15.1%), meaning the stock rose after each sale — a 0% well-timed rate at this ticker. His cross-ticker track record across all prior sales shows an average 90-day return of +5.4% with a 0.00% well-timed rate, indicating a consistent pattern of selling before rallies rather than before declines. The sale follows another AON sale just nine days earlier on 2026-02-17. Aon fundamentals remain solid: FY revenue growth of +9.4%, P/E of 19.26, and a $72.4B market cap, with latest quarterly revenue of $4.0B and net income of $458.0M.

Aon GC Darren Zeidel sold 5,040 shares at $325.79 for $1.6M; stock now -20.8% from 52-week high.

Zeidel sold 5,040 shares (19.9% of his prior holdings) on 2026-02-17 at $325.79 while AON traded well below its 52-week high of $409.32 and was already down 30-day (-4.5%) and 90-day (-6.4%). His same-ticker history at AON shows 3 prior sells, none of which were well-timed at the 90-day mark—the most recent two (2025-11-05) achieved only +0.2% and +0.0% respective 30-day returns, suggesting his prior exit decisions at this ticker did not precede material declines. His cross-ticker track record across all holdings records a 0.00% well-timed rate on 3 prior sells (all poorly timed in hindsight), with a positive average 90-day return of +5.4%, meaning his sells have historically occurred before the stock rose. This ongoing pattern of missed timing, now repeated at AON itself, provides no evidence that the current sale is positioned ahead of further weakness.

AON General Counsel Darren Zeidel sells 8,800 shares (8.8K) for $3.0M, reducing stake by -30.3% to 20,253 shares

Darren Zeidel, AON's General Counsel, executed two separate sales on 2025-11-05 totaling 8,800 shares for $3,031,818.50, reducing his post-transaction holdings to 20,253 shares from 29,053 shares. The blended average sale price was $344.52, slightly below the current price of $346.32 but also -15.4% from the 52-week high of $409.32. His prior sell at this ticker on 2024-07-26 showed a 90-day return of +15.1%, indicating that sale was followed by stock appreciation rather than decline—a pattern inconsistent with well-timed selling. The company reports strong fundamentals with annual revenue growth of +17.4% and a market cap of $74.4B, though the stock is down -5.2% over the past 30 days and -5.5% over 90 days. The transaction itself represents a substantial portfolio reduction (30.3%), warranting examination of context such as estate planning, liquidity needs, or diversification rather than interpretation based solely on price timing or market confidence.

Aon General Counsel Zeidel sold 6,597 shares at $310.00 for $2.0M; retains 24.4K shares post-sale

Darren Zeidel, General Counsel at Aon plc, sold 6,597 shares ($2,045,070 in aggregate value) on July 26, 2024, reducing his holdings from 31,031 to 24,434 shares, a net reduction of 21.3% of his pre-transaction position. The sale occurred at $310.00 per share; the current price of $328.74 is 3.9% below the 52-week high of $342.02, while the stock has appreciated 12.0% over the past 30 days and 15.8% over the past 90 days. The company's fundamentals show $3.8B quarterly revenue, $524.0M net income, 7.2% annual revenue growth, and a P/E of 28.03 on a $71.4B market cap. The sale represents a discrete reduction in Zeidel's AON exposure but does not eliminate his ownership stake; the transaction occurs within the context of a stock that has moved measurably upward in recent months.
