AT&T Swapped Its Scoreboard For A Forecast

The company still reports the numbers it used to lead with, but the case out front now rests on a payoff much further away.

The Story Used To Be Counted Product By Product

If you have held AT&T (T) a couple of years, the story you bought was a build with a scoreboard attached. Roughly two years ago the ambition was stated plainly: “lead the industry in converged connectivity through 5G and fiber.” The proof came product by product, countable: 403,000 postpaid phone net adds in a third quarter, and more than 200,000 AT&T Fiber net adds. The 5G and fiber investment was described then as fueling growth already, not as a later payoff.

Now The Strategic Case Leans On A Traffic Forecast For 2035

The front of the story looks different today. The lead customer figure is a single blended one, more than 1 million Advanced Connectivity subscribers gained across fiber, fixed wireless and postpaid phones, and the strategic case rests on AI. Management’s framing is that agentic AI is reshaping network traffic, citing industry research that AI agents can generate up to 450% more total traffic per task than a human doing the same work, plus projections of roughly 9X growth in enterprise traffic and 7X growth in consumer traffic by 2035.

The asset did not change; the reason to own it did. The same Advanced Connectivity operation now pitched on future traffic already supplies more than 90% of service revenue and nearly all adjusted EBITDA. In the reported financials, trailing twelve-month revenue is about $127 billion and the Communications segment alone runs near $120.9 billion, about 95% of the total. No revenue line sits beside the AI case, only traffic multiples and a horizon no quarterly report can settle.

What The Blended Number Cannot Show You About Fiber ARPU

The business that used to be the headline is not soft, which makes this a pivot rather than a retreat. Revenue over the last twelve months is up 2.6% year over year, against a three-year average pace of 1.6%. Net margin of 16.9% sits well above its 10.8% three-year average and close to its 17.9% three-year peak. Advanced Connectivity service revenue grew 5.1% year over year in the second quarter of 2026, and the consolidated adjusted EBITDA margin rose 110 basis points to 39%, the highest the company says it has recorded since it refocused the business on Advanced Connectivity.

One metric does sit underneath the new frame. Fiber ARPU fell 1.3% from a year earlier, and excluding the footprint acquired from Lumen it was roughly flat. Management says that is a choice: the goal is to maximize total Advanced Connectivity service revenue rather than the ARPU of any single product, and it expects convergence to keep some pressure on Fiber ARPU in the near term. The CFO has also allowed that broadband revenue may come in a little below what the company guided, with wireless a little above.

Reassuring, As Long As Fiber ARPU Holds Its Ground

On the numbers this reads as a pivot made from strength, not a story being managed. What a holder gives up is resolution. A single blended subscriber headline is the place a volume-for-price trade would stay hidden longest, and the company has already said some Fiber ARPU pressure is coming. Postpaid phone net adds have not disappeared: 432,000 landed in the second quarter of 2026; they just are not what the story is built around anymore. So the check when third-quarter 2026 results arrive is narrow: Fiber ARPU excluding the Lumen footprint, read next to converged account growth.

Over the past year the market has not paid for the improvement, with the stock down about 9% against a gain of about 16% for the S&P 500, and at $23.94 against a 52-week high of $28.42. Management’s answer was to lift planned 2026 buybacks by up to 25%, to roughly $10 billion. Whether that gap closes is a question the price answers, and the stocks the market expects to move most are where those expectations show up first.

Even A Pivot This Well-Funded Is Still One Company’s Timetable

None of this is an argument against owning AT&T. It is an argument for knowing whose clock you are on. A case built on traffic that arrives years from now asks you to hold one balance sheet, one regulator and one management team, and the buyback that looks shrewd at $23.94 is only shrewd if the operating case holds. A rules-based portfolio does that job differently, spreading the timing risk across many names and re-balancing on rules, not conviction. If you would rather own a system than a single timetable, that is the comparison to make. The Trefis High Quality (HQ) Portfolio has a track record of outpacing a benchmark that combines the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000.
