Vondran Steven O

AMT CEO Vondran sells 33,482 shares for $6.3M; maintains 105.4K shares; extends track record of well-timed selling.

Vondran Steven O, President and CEO of American Tower Corp, executed 3 separate sales totaling 33,482 shares for $6,309,966.96 at an average price of $188.46 on 2026-03-04, reducing his holdings by 24.1% from 138.9K to 105.4K shares. His cross-ticker track record shows 4 prior sells with a 90-day well-timed rate of 100.00%, and at AMT specifically, all 4 prior sells resulted in negative 90-day returns (ranging from -1.9% to -7.2%), indicating consistent execution ahead of declines. The current stock price of $188.59 is 18.8% below the 52-week high of $232.35, and the 30-day and 90-day price changes of +6.8% and +5.4% respectively suggest recent upward momentum in the context of this sale. The company shows solid fundamentals with $2.7B quarterly revenue, +5.1% annual growth, and a $87.9B market cap, but the insider's historical pattern of well-timed sales—particularly the 100% success rate at this ticker—deserves attention as a potential leading indicator of near-term price dynamics.

AMT CEO Vondran sells 21,537 shares at $230.00 (Aug 2024); 100% well-timed at 90 days across 3 prior AMT sales

Steven O Vondran, President and CEO of American Tower Corp, sold 21,537 shares at $230.00 on 2024-08-02, reducing his holdings from 83,380 to 61,843 shares (-25.8%). This sale occurs in a stock currently priced at $228.16, only -2.8% from its 52-week high of $234.64, and represents a CEO's material reduction in personal exposure at elevated valuation. Notably, Vondran's three prior open-market sells at AMT all demonstrated well-timed 90-day returns (each showing negative 90d returns of -3.0%, -2.7%, and -1.9%), establishing a documented pattern of selling before or near inflection points at this specific ticker. His cross-ticker track record of 100% well-timed sells (3 of 3 transactions) further reinforces disciplined execution on sell signals. The current trade's execution near the stock's 52-week high, combined with the 90-day positive return of +25.8% leading into this sale and the insider's established timing pattern, warrants monitoring of subsequent price behavior to validate or break the pattern.
