Is AT&T (T) Undervalued As Fiber And 5G Optimism Lifts Its Outlook?

Board refresh puts governance in focus for AT&T

AT&T (T) just expanded its board from 10 to 11 directors, bringing in Fazal F. Merchant, a veteran finance executive with extensive transaction and technology experience.

Merchant joins both the Audit and the Corporate Development and Finance Committees. This places him close to oversight of AT&T’s balance sheet, capital allocation and potential deal activity at a time when investors are watching those areas closely.

AT&T shares have picked up some momentum, with a 30-day share price return of 7.46% and a 90-day gain of 10.52%, while the 1-year total shareholder return is still down 7.72%. As a result, recent optimism is building off a weaker starting point.

Recent commentary around fiber and 5G investment, confidence in the earnings outlook and management’s messaging on satellite competition has helped shift the tone. This board refresh also fits neatly into that broader reset story for AT&T.

Spot 89 AI infrastructure stocks that, like AT&T, are leaning into fiber, 5G and AI-driven network investment.

AT&T’s rebound could signal investors are finally giving more credit to the fiber and 5G build than to past missteps. Is this latest move mostly about better business traction or a mood shift in the market, and how does that show up in valuation?

Most Popular Narrative: 10.2% Undervalued

AT&T's most followed narrative pegs fair value at $29.03, compared with the latest close at $26.06, which frames this board refresh against a story of modest undervaluation built on fiber and 5G execution.

Accelerated investments in 5G and fiber infrastructure, supported by recent pro-investment legislation and tax savings, are expanding AT&T's addressable market and improving its ability to capture growing mobile data, video streaming, IoT, and enterprise connectivity demand. This dynamic is directly fueling recurring revenue and future topline growth.

Want to understand why this fair value sits above the current price without assuming rapid expansion? The narrative leans on steady revenue growth, slimmer margins, and a higher future earnings multiple than today. Curious how those ingredients combine into that $29 handle rather than something far higher or lower.

Result: Fair Value of $29.03 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

Still, elevated postpaid churn or weaker returns from fiber expansion into harder to serve areas could quickly challenge the current AT&T optimism narrative.
