Net income of $2.71 billion and EPS of $2.42 (diluted $2.41) underscore a durable profitability profile, even as the company absorbs elevated fixed costs associated with 5G network expansion and device ecosystems. EBITDA reached $7.80 billion, with an EBITDA margin of about 35.5%, signaling strong cash generation despite competitive and capex pressures.
