AMT AMERICAN TOWER CORP /MA/ Insider Trading

Director Kalathur Rajesh buys 2,671 shares of AMT at $185.30; doubles pre-transaction position to 4,936 shares

Kalathur Rajesh, a Director, acquired 2,671 shares of American Tower Corp at $185.30 on 2026-03-10, increasing his total holdings from 2,265 shares to 4,936 shares—a net increase of 117.9%. The purchase totaled $494,936.30. The transaction occurs while the stock trades at $179.86, down 22.6% from its 52-week high of $232.35, suggesting the purchase was made at an elevated price relative to current levels. His cross-ticker track record shows 2 prior sells with a 90-day well-timed rate of 0.00%, indicating minimal predictive success in prior open-market timing; however, this buy represents a discrete discretionary decision independent of that historical pattern. The company's fundamentals remain solid with $2.7B quarterly revenue and a P/E of 24.88, consistent with a large-cap tower operator. The significance derives from the director's substantial dollar commitment ($494.9K) and meaningful percentage increase in personal exposure to the firm.

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 EVP Noel sells 41,209 shares for $7.9M in 4 transactions; 58.2% position reduction to 29,592 shares remaining

Noel Eugene M, EVP & Chief Operating Officer, executed 4 separate sales totaling 41,209 shares for $7,872,919.89 on 2026-03-02, reducing his holdings by 58.2% from 70,801 to 29,592 shares. The blended average price of $191.05 is approximately in line with the current price of $190.80, and the stock is trading 17.9% below its 52-week high of $232.35. His prior sell at AMT on 2024-09-10 saw a -9.2% 30-day return and -12.9% 90-day return, marking a well-timed exit before subsequent decline. This substantial position reduction by a senior operating executive warrants investor attention given the magnitude and the company's stable fundamentals (revenue $2.7B, P/E of 26.39).

CFO Smith sold 34,341 shares for $6,596,527.57 on 2026-02-17; stock now $184.79, down 20.5% from 52-week high

Rodney M Smith, EVP, CFO & Treasurer of American Tower, executed 4 separate sales totaling 34,341 shares (34.3K shares) for $6,596,527.57 ($6.6M) on 2026-02-17, reducing his holdings by 31.6% from 108,655 shares to 74,314 shares. The sales occurred at an average price of $192.09 per share, which was 3.9% above the current price of $184.79 and within the 52-week range. Historically, Smith's prior sales at AMT have been poorly timed: 4 of his 5 previous sales at this ticker saw positive 90-day returns, meaning the stock appreciated after he sold, and his same-ticker timing pattern shows only 1 of 5 prior sales were well-timed at the 90-day mark. The volume and concentration of this sale, combined with weak recent fundamentals (annual revenue down 9.1% year-over-year) and elevated valuation (P/E of 28.61), suggest a material reduction in the CFO's direct exposure to the company.

Director Eugene F Reilly bought 5,554 shares of American Tower (AMT) for $994,110.46, raising holdings by 4114.1% to 5,689 shares.

REILLY EUGENE F purchased 5,554 shares at $178.99 on 2025-10-31, increasing his position from 135 to 5,689 shares—a dramatic 4114.1% expansion in holdings. The purchase occurred when the stock trades at $180.35, only 22.4% below its 52-week high of $232.35, and after a 13.7% decline over the prior 90 days. The company operates with a strong absolute revenue base ($2.7B quarterly) and earnings ($912.6M net income), though growth has contracted -9.1% year-over-year. This substantial accumulation by a director at near-peak valuations (P/E 27.92, market cap $84.4B) at a time when the stock is down significantly from recent highs warrants investor attention to both the insider's conviction and the underlying business trajectory.

Sanjay Goel (EVP, Asia-Pacific) sold 4,000 AMT shares at $215.92; stock now $213.76. His prior AMT sales (3) were 2 of 3 well-timed 90-day lookbacks.

Goel sold 4,000 shares on 2025-03-17 at $215.92, reducing his AMT position by 13.6% to 25,408 shares. His prior trades at AMT show mixed outcomes: 2 of 3 prior sells delivered negative 90-day returns (well-timed), while one returned +11.8% over 90 days. The stock is currently $213.76, down from the transaction price and down 12.0% from its 52-week high of $242.83, though it has risen 12.9% over the past 30 days and 19.2% over 90 days. AMT trades at a notably elevated P/E of 50.53 on negative net income of $-780.4M against quarterly revenue of $2,522,300,000.00, with annual revenue declining 9.1% year-over-year. The combination of Goel's prior pattern of well-timed sells at this ticker and the current valuation backdrop warrants observation of his future trading activity.

Director REEVE PAMELA D A sold 4,971 shares of AMT at $202.97 on 2025-02-26 for $1,008,963.87

Pamela D A Reeve, a director, sold 4,971 shares at $202.97, reducing her stake from 24,605 shares to 19,634 shares—a 20.2% reduction in holdings. AMT is currently trading at $205.62, up 12.0% over the past 30 days, though the stock remains 15.3% below its 52-week high of $242.83. The company's fundamentals show material headwinds: net income is negative at -$780,400,000.00, annual revenue declined 9.1% year-over-year, and the stock trades at a 48.61 P/E despite the loss. The director's sale occurred during a period of recovery in stock price, with the security having rebounded from lower levels in recent weeks. Without accompanying context on trading plan status or compensation-related drivers, the sale primarily reflects a modest reduction in director exposure to this challenged enterprise.

SVP & CAO Robert Joseph Meyer Jr sells 5,663 shares ($1.1M) at $201.67 blended avg; retains 26.2K shares post-sale

Meyer Robert Joseph JR, SVP & Chief Accounting Officer, executed 2 separate sales totaling 5,663 shares for $1,142,057.90, reducing his holdings from 31,873 shares to 26,210 shares (-17.8% vs pre-transaction holdings). The transactions occurred at $201.12 on 2025-02-26 and $202.18 on 2025-02-27, blending to $201.67, slightly below the current price of $205.62. The company is trading 15.3% below its 52-week high of $242.83 and reports a net loss of $-780,400,000.00 in the latest quarter against revenue of $2,522,300,000.00, with annual revenue declining 9.1% year-over-year. The sale occurs in a context of deteriorating profitability and elevated valuation (P/E 48.61), though Meyer retains substantial post-transaction holdings, limiting the signal to a partial portfolio reduction rather than a complete exit.

AMT CFO Rodney Smith sold 16.6K shares for $3.1M (blended avg $189.70) on 2025-02-13; reduced holdings by -20.9%

Smith Rodney M, EVP, CFO & Treasurer, completed two separate sales totaling 16,568 shares for $3,143,017.42 on 2025-02-13, reducing his AMT holdings from 79,360 to 62,792 shares. His cross-ticker track record shows a 90-day well-timed rate of 81.82%, indicating his prior open-market sells have generally preceded stock declines. At American Tower specifically, his three prior measurable sells all posted negative 90-day returns (-7.5%, -7.9%, -0.3%), consistent with well-timed exits. The current price of $189.55 is -21.9% from the 52-week high of $242.83, and the company is trading at a P/E of 83.50 with negative net income of -$780,400,000.00 in the latest quarter, suggesting elevated valuation relative to profitability. The combination of a substantial reduction in stake (20.9% of prior holdings) by an officer with a demonstrated pattern of well-timed sells at this ticker warrants investor attention to the company's near-term trajectory.
