AT&T Inc. and Banco Bilbao Vizcaya Argentaria, S.A. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between AT&T Inc. and Banco Bilbao Vizcaya Argentaria, S.A..

AT&T Inc. business model: AT&T runs a capital-intensive network business. It buys licensed wireless spectrum, builds and upgrades cell sites, and trenches fiber, then charges consumers and businesses a monthly fee to use that network. Capital investment was $22.0 billion in 2025 against $125.6 billion of revenue. Most of the revenue is recurring subscription revenue, so the economics turn on churn: postpaid phone churn was 0.98% in the fourth quarter of 2025. Device sales add about $22.1 billion a year at much lower margin than service.

Banco Bilbao Vizcaya Argentaria, S.A. business model: BBVA runs a universal banking model built on local subsidiaries that fund themselves with local deposits, so a shock in one country does not drain the parent. Customer deposits reached ~$568B (EUR502.5B) at the end of 2025 against ~$534B (EUR472.7B) of gross loans, and net interest income of ~$29.7B (EUR26.280B) provided about 71 percent of gross income. Fees from payments, cards, asset management and insurance added ~$9.28B (EUR8.215B) and net trading income ~$3B (EUR2.656B). Distribution is mostly digital: 81.2 million active customers were served through 5,642 branches and 31,015 ATMs, and the efficiency ratio of 38.8 percent is one of the lowest among large European banks.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of AT&T Inc. stack up against those of Banco Bilbao Vizcaya Argentaria, S.A..

AT&T Inc. competitive advantage: AT&T's advantage is the cost of replicating what it already owns. Its fiber network passed 32.0 million consumer and business locations at the end of 2025, and its mid-band 5G service covers more than 310 million people. Keeping that going took $22.0 billion of capital investment in 2025 alone, which is why the national market has three carriers rather than thirty. AT&T also builds and operates FirstNet for the FirstNet Authority under a 25-year contract awarded in 2017, a public safety network with more than 7 million connections and no direct equivalent. Because connectivity is sold on monthly subscriptions, revenue moves slowly in both directions.

Banco Bilbao Vizcaya Argentaria, S.A. competitive advantage: BBVA's first advantage is scale in Mexico, where BBVA Mexico is the largest bank in the country and produced ~$5.95B (EUR5.264B) of net attributable profit in 2025, close to half the group total. The second is cost: operating expenses grew 1.0 percent in euros in 2025 while gross income grew 4.1 percent, holding the efficiency ratio at 38.8 percent with a branch network trimmed to 5,642 offices. Group ROTE of 19.3 percent is a level BBVA describes as leading among large European banks.

Future prospects matter as much as current results. The growth strategies below explain how AT&T Inc. and Banco Bilbao Vizcaya Argentaria, S.A. each plan to expand from here.

AT&T Inc. growth strategy: With the US smartphone market saturated, AT&T's growth depends on home internet and on keeping the wireless customers it has. It is building fiber, which passed 32.0 million consumer and business locations at the end of 2025 and carried 10.4 million subscribers, and it sells AT&T Internet Air fixed wireless where fiber is not available. In wireless the emphasis is retention: AT&T offers existing customers the same trade-in promotions as switchers and spreads the credits over 36-month device installment plans, which held postpaid phone churn at 0.98% in the fourth quarter of 2025. The Lumen mass markets fiber purchase, completed in February 2026, added more than 1 million subscribers and more than 4 million fiber locations in metros including Denver, Seattle and Salt Lake City.

Banco Bilbao Vizcaya Argentaria, S.A. growth strategy: After the Banco Sabadell offer lapsed in October 2025, BBVA's growth plan rests on organic lending, digital expansion in Europe and capital returns. Loans and advances to customers grew 11.5 percent in 2025 and customer funds 13.5 percent. The group opened a branch-free digital bank in Italy in October 2021, which passed 800,000 customers by its fourth anniversary and targets one million during 2026, and launched a second digital bank in Germany in June 2025. Capital released by the 2021 transfer of BBVA USA to PNC still underpins buybacks and dividends, with half of 2025 profit earmarked for shareholders.
