NEW YORK, March 17, 2026, 19:35 EDT
AT&T Inc. picked up 0.4% to close at $27.85 on Tuesday, outshining other major U.S. wireless names after it announced a fresh enterprise AI partnership with Cisco and Nvidia. Verizon shed 0.9% and T-Mobile slid 0.7%. For comparison, the S&P 500 added 0.25%.
Timing’s key here. Over the past few weeks, AT&T has dialed up its push into fiber, 5G, and enterprise infrastructure—staking out these areas as central to its next chapter. The company recently detailed a $250 billion U.S. network spend, spread over five years. First-quarter results arrive April 22, debuting a revamped structure designed to separate growth engines from declining legacy businesses, aiming to give investors a sharper read.
AT&T and Cisco announced a joint solution that bundles networking, edge computing, and IoT security, all powered by Nvidia infrastructure. The idea: push AI tasks out to the edge—closer to cameras, sensors, and devices—rather than routing all the data back to a remote cloud. According to the companies, they’ve already put this system through its paces, citing a public-safety demo in Dallas and a trial run at an industrial site in Louisiana.
AT&T Business senior VP of product Shawn Hakl calls secure AI services “pivotal” for the company’s IoT approach. Nvidia’s Chris Penrose describes telecom networks as the “heart” driving distributed AI expansion. Cisco’s Masum Mir points to potential gains for enterprise developers working at the network edge.

AT&T has tried to make its case with heftier network plays. Back in January, the company projected 2026 adjusted earnings above what Wall Street had penciled in, a target linked to its Lumen fiber acquisition and the EchoStar spectrum agreement. According to AT&T, 42% of fiber homes also subscribe to its 5G service. For the fourth quarter, it reported 421,000 new postpaid phone lines and 283,000 additional fiber subscribers.
CFO Pascal Desroches recently flagged to investors that first-quarter numbers would reflect some of the expansion costs. He projected EBITDA growth in the low single digits, with free cash flow expected between $2 billion and $2.5 billion. Lumen integration and related transaction expenses are set to hit results for the period, even as AT&T moves toward splitting out Advanced Connectivity and Legacy Communications in its financial reporting.
The short-term outlook remains muddled. AT&T flagged that leverage—net debt to adjusted EBITDA—might climb to roughly 3.2 times following the EchoStar deal, but management expects it to ease closer to 3 times by the end of 2026. Desroches has signaled that first-quarter profit and cash flow will lag the yearly run rate. On top of that, rising oil prices have led investors to pare back their bets on Fed rate cuts.
“It’s about execution,” Desroches told investors back on March 9. After wrapping up the Lumen deal, AT&T sits above 36 million fiber locations, with 40 million targeted by the end of 2026. Next up: April 22 earnings, a checkpoint for whether the company can back up its AI narrative with real traction in fiber and wireless. AT&T Investor Relations
