TMUS T-Mobile US, Inc. Insider Trading

Jon Freier, then-COO, sold 4,799 TMUS shares at $190.00 via 10b5-1 plan; retains 217,167 shares.

Jon Freier, who was COO at the time, disposed of 4,799 shares (2.2% of pre-transaction holdings) under a 10b5-1 trading plan adopted on 2026-02-19, making this a scheduled transaction rather than a discretionary choice. His remaining position of 217,167 shares remains substantial. The transaction price of $190.00 compares unfavorably to the current price of $191.11, and TMUS is down 26.9% from its 52-week high of $261.56. Across his prior sales at TMUS, outcomes have been mixed: two sales showed strong 90-day returns (+22.5%, +18.9%), while another showed a negative 90-day outcome (-9.0%), indicating no consistent timing signal in this executive's TMUS trading history.

Chief Broadband Officer at T-Mobile buys ~5,100 shares in open market; stock trading well below recent highs.

Almeida Andre, T-Mobile's Chief Broadband, Enterprise & Emerging Services Officer, made a substantial open-market share purchase while the stock is trading significantly below its recent highs—a classic setup where insiders typically act on confidence that the market has overreacted. The purchase represents a meaningful commitment equal to roughly 13% of his existing holdings, suggesting conviction rather than automatic rebalancing. T-Mobile remains a profitable company with strong revenue growth, providing a solid operational foundation. This timing—buying during a pullback rather than at peaks—aligns with how experienced insiders typically deploy personal capital, and Andre's operational role means he has direct insight into the broadband and enterprise segments driving future growth. The filing warrants attention because it combines insider action from someone with genuine company knowledge with a buying pattern that historically precedes stock rebounds.

TMUS CLO Nelson Wolfe sold 2,329 shares at $222.38 on 2026-02-24; stock down 19.8% from 52-week high.

Nelson Mark Wolfe, Chief Legal Officer, sold 2,329 shares for $517,968.16, reducing his position from 68,006 to 65,676 shares. The sale occurred at $222.38, while the stock now trades at $218.66, down 19.8% from its 52-week high of $272.83 but up 16.3% over 30 days and 5.8% over 90 days. His prior three measurable sales at TMUS (February 2025) were all well-timed at the 90-day mark, with post-sale declines ranging from -8.2% to -9.5%, suggesting a pattern of selling ahead of pullbacks at this specific ticker. The most recent transaction follows two other TMUS sales within the past week (2026-02-17 and 2026-02-18), though outcomes for those are not yet measurable. Against TMUS fundamentals (revenue $22.0B, net income $2.7B, 8.5% revenue growth, P/E 20.90), this activity appears part of a recurring periodic rebalancing pattern rather than a response to material adverse news.

Director Sievert sold 15,000 TMUS shares for $3,302,988.42; holdings drop to 125.7K shares

Director G Michael Sievert executed 2 separate sales totaling 15,000 shares (15.0K shares) for $3,302,988.42 at an average price of $220.20 on February 23–24, 2026, reducing his holdings by 10.7% to 125.7K shares. At the current price of $218.66, the executed trades are underwater by approximately $21.05 per share, though this reflects post-transaction market movement rather than timing of the sale itself. The TMUS-specific track record shows 2 of 4 prior measurable sales were well-timed at the 90-day horizon, indicating a mixed historical pattern at this ticker. The company's fundamentals remain solid with $22.0B quarterly revenue, $2.7B net income, and 8.5% annual revenue growth, though the stock trades at a 19.8% discount to its 52-week high and is up 16.3% over the past 30 days—a recovery context in which a director chose to sell. Without evidence of coordinated activity or material non-public information, the transaction reflects a routine portfolio adjustment by a single director.

Director G Michael Sievert sold 80,000 TMUS shares at $214.94 for $17.2M on 2026-02-19, reducing holdings -36.2%.

G Michael Sievert, a director at T-Mobile US, executed a substantial open-market sale of 80,000 shares on 2026-02-19 at $214.94, generating $17,195,200.00 in proceeds and cutting his holdings from 220.7K to 140.7K shares. This represents a -36.2% reduction in position size. At his prior trades at TMUS across 5 historical sales, 2 of 4 measured outcomes showed negative 90-day returns after the sale—consistent with well-timed selling before subsequent declines—though 2 also showed positive 90-day returns. His cross-ticker track record shows an avg 90d return of +4.1% after 20 prior sells with a 21.05% well-timed rate. The current stock price of $219.95 is -19.4% from the 52-week high of $272.83, and has gained +18.2% over the past 30 days since the sale date, suggesting the initial sale price outperformed near-term momentum. With revenue at $22.0B, net income of $2.7B, +8.5% annual growth, and a P/E of 21.03, the company maintains solid fundamentals; the magnitude of this single director sale should be evaluated in context of the broader $242.4B market capitalization and ongoing business performance.

CFO Osvaldik Peter sold 27,000 TMUS shares at $214.86 for $5.8M, reducing holdings by 34.4%

Osvaldik Peter, CFO of T-Mobile US, executed a substantial open-market sale of 27,000 shares on 2026-02-18 at $214.86, reducing his holdings from 78,572 to 51,572 shares. At his cross-ticker track record, the insider's 4 prior sells averaged -0.8% returns at 90 days with a 50.00% well-timed rate, indicating mixed timing precision historically. At TMUS specifically, his prior 4 sales show a 50% well-timed rate at the 90-day mark (2 of 4 sales followed by declining prices). The stock currently trades at $215.30, only 2.2% above the sale price but 21.1% below its 52-week high of $272.83, having gained 17.2% over 30 days. The company maintains solid fundamentals with $22.0B quarterly revenue, $2.7B net income, 8.5% annual revenue growth, and a P/E of 20.58, suggesting the sale reflects portfolio adjustment rather than distress at the underlying business. Investors should monitor whether this significant 34.4% reduction signals a material change in the CFO's conviction or simply reflects personal liquidity needs alongside the stock's recent sharp rebound from lows.

Nelson Mark Wolfe sold 16,514 shares (19.5% of holdings) for $3,639,327.06 at $220.80 and $219.69

Nelson Mark Wolfe, Chief Legal Officer & GC of T-Mobile US, Inc., executed 2 separate sales totaling 16,514 shares for $3,639,327.06, reducing his holdings by 19.5% from 84,520 to 68,006 shares. The blended average price was $220.38, which is $7.13 above the current price of $213.25 and notably above the 52-week low of $183.60. Examining Wolfe's prior trade history at TMUS, 4 of his 5 previous sales were well-timed at the 90-day mark, indicating a pattern of selling before subsequent declines; however, the timing characterization applies only to his prior disclosed trades, not this filing itself. This sale occurs in February 2026 while the stock is up 14.4% over the prior 30 days but still 21.8% below the 52-week high, within the context of solid fundamentals (net income of $2,714,000,000.00 on revenue of $21,957,000,000.00 with 8.5% annual growth).

TMUS Director Raul Marcelo sold 550.0K shares for $119.7M at $217.57; holdings reduced 38.2% to 891.2K shares

Raul Marcelo, a Director, sold 550,000 shares of T-Mobile US at $217.57 on 2026-02-12 for $119,663,500.00, reducing his holdings by 38.2% from 1,441,204 to 891,204 shares. Notably, his prior 5 sells at TMUS have posted a 0.00% well-timed rate at the 90-day mark, with all five prior transactions followed by positive returns (ranging from +3.9% to +24.4%), indicating his historical TMUS sales have not preceded declines. The current stock price of $219.61 is -19.5% from the 52-week high of $272.83 but +17.9% over the past 30 days, suggesting a partial recovery from recent weakness. This sale's signal value is contextually limited by the absence of a timing advantage evident in his same-ticker history.

Director SIEVERT G MICHAEL sold 45,000 shares of TMUS for $9,702,450.00 under pre-arranged 10b5-1 plan

Director SIEVERT G MICHAEL executed 2 separate sales totaling 45,000 shares for $9,702,450.00 at prices of $216.97 and $214.25 on November 17-18, 2025. This transaction was conducted under a pre-arranged 10b5-1 trading plan adopted on 2024-11-14, meaning the sales were scheduled rather than discretionary. The reduction represents -13.6% of his pre-transaction holdings, leaving him with 286,195 shares post-transaction. As a scheduled disposition under a 10b5-1 framework, this sale reflects a pre-planned execution rather than a discretionary timing decision by the director.

TMUS CEO Gopalan Srini purchases 9,800 shares ($1,977,836) amid -24.5% drawdown from 52-week high, boosting holdings 12.2%

Gopalan Srini, President and CEO, purchased 9,800 shares of T-Mobile at $201.82 on 2025-11-06, totaling $1,977,836.00, increasing his holdings by 12.2% from 80,458 to 90,258 shares. The purchase occurs while the stock is down 24.5% from its 52-week high of $272.83 and has declined 10.0% over the past 30 days and 18.4% over 90 days. The absolute dollar magnitude ($2.0M) and the percentage increase in his personal holdings (12.2%) represent a material accumulation during a period of significant price weakness. Given the company's solid fundamentals—$22.0B quarterly revenue, $2.7B net income, and P/E of 19.40—this transaction merits investor attention as a signal from the company's top executive during a downturn, though the restricted context prevents attribution of forward-looking intent.
