Why Televisa's $2 Billion AT&T Mexico Buy Is a Direct Threat to Carlos Slim's Dominance

Grupo Televisa and Fintech Holdings have struck a $2 billion agreement to acquire AT&T's entire wireless business in Mexico — a transaction Bloomberg described as one of the country's most consequential corporate deals in recent memory. The move hands Mexico's preeminent broadcaster its first viable entry into the mobile sector while placing a well-capitalized, nationally rooted rival directly in the path of Carlos Slim's Telcel, which commands roughly 59% of the Mexican wireless market.

Under the terms disclosed Tuesday, Televisa and Fintech Holdings will each hold a 50% stake in the acquiring consortium. The partners plan to finance the purchase through a combination of cash and secured debt. The $2 billion price remains subject to final closing adjustments, and AT&T retains the right to additional contractual and contingent benefits under the agreement.

What the Numbers Reveal

AT&T Mexico closed 2025 with consolidated revenues of 85.4 billion pesos — approximately $4.65 billion at current exchange rates — and operating income of 1.4 billion pesos, figures Televisa cited in its public disclosures. The unit carried roughly 24.7 million wireless subscribers at year-end 2025, though that figure had declined to about 23.4 million by June 30, 2026, after shedding more than 1.2 million users across the first two quarters of the year.

Scotiabank analysts labeled the $2 billion price a "bargain," projecting the deal will push Televisa's combined share of total fixed and wireless subscribers in Mexico from 8% to an estimated 19%. Markets responded immediately: Televisa shares surged 5% in after-hours trading on the New York Stock Exchange the day the agreement was made public.

A Broadcaster's Second Chance at Wireless

Televisa is not entering mobile for the first time. An earlier push to establish a wireless presence between 2012 and 2014 failed to gain traction, leaving the broadcaster sidelined as rivals consolidated. The difference this time is a co-equal financial partner and a concrete integration roadmap: merging AT&T Mexico's mobile network with Televisa's existing izzi fixed broadband and Sky satellite pay-TV operations under a single converged platform.

The infrastructure Televisa is acquiring also carries substantial embedded value. Since 2018, AT&T had channeled more than $6 billion into expanding and modernizing its Mexican wireless network — a capital base the new owners inherit at a steep discount to its cumulative cost.

The Man Behind Fintech Holdings

Fintech Holdings is far from a passive financier. The firm belongs to Mexican billionaire David Martínez, who launched Fintech Advisory in 1987 and has since built a decades-long record of strategic investment in Latin American telecom and infrastructure assets. AT&T said Fintech brings "fresh capital, local knowledge, and operational expertise in the Mexican wireless sector" — language that signals an active management role rather than a silent stake.

AT&T's Twelve-Year Mexican Experiment

AT&T's push into Mexico unfolded in two moves: the November 2014 acquisition of Iusacell for approximately $2.5 billion, followed by the January 2015 purchase of Nextel Mexico for roughly $1.875 billion — a combined outlay exceeding $4.3 billion before a single peso of subsequent network or operational spending. Twelve years on, the bet on disruption never materialized at scale. AT&T Mexico remained the country's third-largest carrier, well behind Telcel and unable to close the subscriber gap through sustained investment.

AT&T Chairman and CEO John Stankey framed the divestiture as strategic reallocation, not retreat. Stankey said the company believes "the AI future will run on converged networks with dense fiber assets," signaling that Mexico's sale proceeds will accelerate a domestic fiber expansion targeting more than 60 million U.S. locations by 2030. Prior to close, AT&T will reclassify AT&T Mexico as a held-for-sale asset, a designation that will appear in its third-quarter 2026 10-Q filing with the SEC.

18,000 Employees, One Transition

AT&T Mexico CEO Mónica Aspe Bernal notified employees directly following the announcement, assuring the company's roughly 18,000 workers — based across approximately 6,000 retail locations nationwide — that operations would continue under the current structure until the deal closes. Aspe Bernal confirmed the Q1 2027 target timeline and emphasized that customer service and day-to-day priorities remain unchanged in the interim.

The Regulatory Hurdle

The transaction cannot proceed without clearance from Mexico's telecommunications regulators — a review process that could run into early 2027. Once approved, the Televisa-Fintech consortium will assume operational control of a mobile business providing wireless, mobile internet, and related services to tens of millions of subscribers across the country.

The competitive backdrop gives the deal added weight. Earlier in 2026, Telefónica agreed to sell Movistar Mexico for just $450 million — less than a quarter of the Televisa-Fintech price — underscoring the structural difficulty foreign operators have faced in sustaining returns against Telcel's market weight. Televisa, embedded in Mexican media and content for decades and already operating a national broadband footprint, steps into mobile with competitive assets its predecessors simply did not possess.

If regulators greenlight the transaction on schedule, Mexico's wireless market will carry a fundamentally different competitive profile into 2027 — one where Carlos Slim's Telcel, for the first time in years, confronts a convergent rival built on local roots, national content reach, and combined broadband and mobile scale.
