Why Does AT&T Stock Still Trade Like It Is Shrinking?
AT&T (T) trades at 8.2 times earnings against an S&P 500 median of 23.0, and it got there the hard way: the stock returned -9.4% over the past year while the index returned +19.3%. A profitable telecom throwing off cash at that discount is what value buyers hunt for.
Does AT&T Still Turn Its Network Into Cash?
AT&T sells wireless service, AT&T Fiber and fixed wireless home internet to households and businesses, and it turns $127.2 billion of annual revenue into cash reliably. The free cash flow yield is 9.9%.
The earnings behind that single-digit multiple are not thinning either. Operating margin over the past twelve months was 20.6%, ahead of the S&P 500 median of 18.6%, and the margin did not shrink versus the year before. Revenue over the past twelve months grew 2.6%. On those tests this looks like a bargain.
Why Does AT&T Barely Grow?
Widen the window, and that growth thins. The three-year average annual revenue growth is 1.6%, against an S&P 500 median of 8.4%. On a record like that, cheap starts to look earned.
Fiber ARPU declined 1.3% year over year in the second quarter of 2026, but that mostly reflects the lower-ARPU subscribers in the footprint acquired from Lumen, and excluding those customers, Fiber ARPU was approximately flat. Management expects convergence to put some near-term pressure on it. Net debt was 2.68 times adjusted EBITDA at the end of the second quarter and moved to the 3.2 times range now that the EchoStar spectrum purchase has closed.
Is AT&T Shrinking Or Switching Off Its Copper?
Look inside the second quarter of 2026, and that flat record splits in two. Advanced Connectivity, over 90% of service revenue and nearly all of adjusted EBITDA, grew service revenues 5.1% year over year. The legacy segment’s service revenues fell 26% in the same quarter as the company powers its copper network down.
That retirement is already partly approved: AT&T can discontinue legacy services in over 30% of its wire centers, effective by late 2026. Meanwhile, it added more than 1 million Advanced Connectivity subscribers from fiber, fixed wireless, and postpaid phones in the second quarter of 2026, and its consolidated adjusted EBITDA margin reached 39.1%, its highest since the business refocused on Advanced Connectivity.
The test is management’s own guide: free cash flow above $18 billion in 2026, with planned buybacks lifted from about $8 billion to roughly $10 billion, pulled forward from later years. Clearing that hurdle, with leverage returning to management’s 2.5-times target about three years after the EchoStar close, would suggest that the market has been pricing in the shrinking sliver of the business that is being switched off.
On what has already landed, the discount looks like sentiment rather than decay. The margin held, the cash converted, and management raised a buyback instead of cutting an outlook.
That does not make AT&T a growth stock. You would be betting that the cash keeps arriving and keeps funding the dividend and the buyback, while the copper cost base comes out and leverage comes back down. Our Buy the Dip screen lines up the marked-down names, so you can see which discounts still have a working business behind them.
