Insights

Insider Transactions Analyst

CEO reported an open-market purchase of TMUS shares, increasing direct ownership; a straightforward positive insider signal.

Form 4 discloses that the President and CEO of T‑Mobile US, Inc. purchased 9,800 shares of common stock on 11/06/2025 at a weighted average price of $201.82 (individual trades ranged from $201.65 to $201.94). Following this transaction, direct beneficial ownership stands at 90,258 shares. Based on the reported average price, the outlay is approximately $1,977,836.

Form 4 is the SEC’s two‑day disclosure for insiders’ trades. An open‑market purchase by a director and officer increases personal economic exposure and is generally viewed as supportive, though it does not change operations or guidance. The filing also notes that detailed trade breakdowns within the price range are available upon request, which is standard for weighted‑average reporting.

Key items to watch include any subsequent Form 4 filings that show additional purchases or changes in direct/indirect holdings, and the consistency of ownership levels through year‑end reporting. The next few weeks to Q1 2026 are a reasonable window to observe whether similar transactions recur or if this was a one‑off increase.
