T-MOBILE US INC
1,783 institutions still hold T-MOBILE US INC as of Q1 2026. Tracked across SEC 13F-HR filings, with insider and 13D/G activity surfaced alongside.
T-Mobile US Inc (ticker TMUS, CUSIP 872590104) is the third-largest U.S. wireless carrier by subscribers, trailing Verizon and AT&T, but consistently winning the growth-share and customer-satisfaction dimensions through aggressive investment in 5G mid-band spectrum, unlimited-plan price leadership, and post-merger integration of legacy Sprint spectrum assets. Its 13F institutional holder set is compact: eleven institutions reported $7.81M in aggregate Q2 2026. The quarter's dominant trade was MassMutual Private Wealth & Trust adding 2,922 shares — from 12,216 to 15,138 — enlarging its TMUS position by 23.9% in a quarter, reflecting continued conviction in the carrier's share-gain trajectory and improving EBITDA margins. The valueChange of -$26.6K indicates TMUS stock declined slightly in price during Q2; MassMutual's addition was therefore executed at a modestly lower entry point. The selling was told by Eastern Bank (-341 shares, -$167K), Versant Capital (-242 shares, -$115K), Hilltop National Bank (-67 shares, -$406K from the elevated prior quarter base), and Sarver Vrooman (-6 shares, -$9K). CX Institutional cut 935 shares and -$441 from a 5,793-share base. Only Cedar Mountain added 12 shares. No new entrants this quarter.
