AT&T

Website

AT&T sells mobile phone plans and home internet to households and businesses across the US, and runs a wireless business in Mexico. Its business rests on two networks: a nationwide 5G wireless network and a fiber internet network that is replacing its old copper phone lines. Companies and government agencies also buy private networks, security and connectivity services from its business unit. Most revenue comes from monthly service plans plus device installment payments, and the company pushes customers to combine phone and home internet. AT&T Inc. began in 1983 as Southwestern Bell, took the AT&T name after buying its former parent in 2005, and is based in Dallas, Texas.

Simplify's Take

What believers are saying

  • Fiber is AT&T's main growth bet: it targets over 40 million fiber locations by December 2026.
  • Fiber growth includes acquisitions: AT&T's February 2026 purchase of Lumen's consumer fiber unit added over 1 million customers.
  • AT&T is investing in offices: a $1.35 billion Plano campus, announced January 2026, will house nearly 6,000 staff.

What critics are saying

  • Debt stays high for years: AT&T expects about three years after its EchoStar purchase to restore its 2.5x debt target.
  • The workforce is shrinking: AT&T's headcount fell from about 141,000 to 133,000 in the year to December 2025.
  • FirstNet depends on Washington: a federal authority oversees AT&T's first-responder contract and needs renewal from Congress.

What makes AT&T unique

  • AT&T runs the national first-responder network: its FirstNet federal contract lasts until 2042.
  • AT&T bought more airwaves in July 2026: its $23 billion EchoStar deal added spectrum across about 400 markets.
  • AT&T sells phone and home internet together: 42.5% of its advanced internet homes also used AT&T wireless.

AT&T, Pfizer and Zoetis offer yields up to 5.8% with shares under $100

Rising interest rates and bond yields have made dividend stocks less appealing, pushing many lower and their yields higher. Three that trade below $100 are AT&T, Pfizer, and Zoetis, according to The Motley Fool. AT&T trades around $21, down about 16% this year, with a price-to-earnings (P/E) multiple of 11 against 23 for the S&P 500. It yields 5.3% after revenue grew more than 5% in the September quarter. Pfizer trades near $30 and yields 5.8%. Its forward P/E is 10, though its shares are down more than 30% over five years. Zoetis, down 37% this year, trades below $80 with a P/E of 13 and a yield of about 2.6%. Its payout ratio is around 34% of earnings, and it has 12 potential blockbusters in its pipeline.

Collin County office space runs short as AT&T and Samsung relocate; 13M SF pipeline is years away

Space is getting scarce in Collin County, Texas. A company seeking 250,000 SF has roughly four Class A office buildings to choose from, KDC Senior Vice President Aarica Mims told Bisnow. Relocations by AT&T and Samsung Electronics America are lifting demand in Frisco, Plano, and McKinney. Talent, quality of life, and quick-moving local officials are the draws. Most new supply is years away. Karahan Cos. and KDC plan about 11M SF of custom office space at Fields in Frisco, and the Dallas Stars' $3B district in Plano could add up to 2M SF. KDC is seeking about $3.5B in financing for AT&T's 2.3M SF Plano campus. State filings point to a December 1 construction start. Tenants must choose between existing space and build-to-suit.

AT&T's 12.5% cash yield hides $167B net debt, cutting it to 5.7%

AT&T generated free cash flow equal to 12.5% of its market value over the last twelve months, against 4.3% for the median S&P 500 company. Much of that yield reflects heavy debt: net debt stood at $167 billion at the end of September, above its $143 billion market value. Revenue grew 3.5% and operating margin widened to 21.4% from 19.5%. Free cash flow fell to $17.8 billion from $20.0 billion a year earlier. Debt rose after AT&T bought spectrum licences from EchoStar for $23 billion at the end of July. Net debt reached 3.13 times adjusted EBITDA, up from 2.68 times at the end of the second quarter. Management targets free cash flow of $18 billion for 2026, $19 billion for 2027, and $21 billion for 2028. It expects to bring the debt ratio back to about 2.5 times during 2029.

AT&T down 16% on Starlink fears, but 5.3% yield and eight times earnings look cheap

AT&T shares are down 16% this year and trade near their 52-week low, as investors worry that Starlink, owned by Space Exploration Technologies Corp (SpaceX), could become a major mobile carrier and lure away customers. The stock trades at a forward price-to-earnings multiple of eight and yields 5.3%, against an S&P 500 average of 1.1%. Verizon chief executive officer Dan Schulman says a Starlink push could cost hundreds of billions of dollars and take at least four years. He added that it "will basically look and feel like every other network." AT&T's third-quarter revenue rose 5.3% year over year to $32.3 billion. The company called it its best consolidated service revenue growth in more than four years.

AT&T and T-Mobile step up AI security spending as AT&T eyes $18B free cash flow

AT&T and T-Mobile are spending more to protect customer data and networks from AI-related security threats, executives from both companies told Reuters. They said fully self-running networks are still years away. T-Mobile chief technology officer John Saw said the company is improving threat monitoring and working with vendors to close security holes quickly. T-Mobile's breaches in 2021 and 2023 affected over 100 million customer accounts. AT&T chief technology officer Jeremy Legg said some risks lie outside the company's control. AT&T uses encryption, multi-factor authentication, and human oversight of data access. In the third quarter, AT&T's free cash flow was about $5 billion, and capital spending was $5.6 billion.
