Investing.com -- T-Mobile US Inc (NASDAQ: TMUS) reported first quarter results that exceeded analyst expectations, driven by stronger-than-expected postpaid account growth and service revenue gains.

The wireless carrier posted adjusted earnings per share of $2.27, beating the analyst consensus of $2.05 by $0.22. Revenue reached $23.11 billion, surpassing estimates of $22.97 billion and marking an 11% increase from the prior year.

Net income declined 15% YoY to $2.5 billion, impacted by UScellular merger-related costs, including accelerated depreciation of $476 million net of tax. Core adjusted EBITDA increased 12% YoY to $9.2 billion, while adjusted free cash flow grew 5% YoY to $4.6 billion.

"We reported accelerating postpaid net account growth and strong postpaid ARPA growth, reflecting this team's differentiated ability to not only attract new customer relationships but also deepen the engagement with our existing base," said Srini Gopalan, CEO of T-Mobile.

The company raised its full-year 2026 guidance across multiple metrics.
