AT&T's Q4 Beat: Was the Good News Already Priced In?

The numbers were strong, but the market's reaction told the real story. AT&T's fourth-quarter earnings delivered a clear beat, with EPS of $0.52 coming in well above the $0.46 forecast-a 13% surprise. Revenue also topped expectations at $33.5 billion versus the $32.87 billion consensus. The immediate response was a powerful 9.26% pre-market stock surge, a classic "buy the rumor" pop.

Yet that pop was short-lived. The subsequent pullback frames a classic "sell the news" dynamic. The good news was largely anticipated. The market had already priced in a solid quarter, leaving little room for a sustained rally on the actual print. The expectation gap had closed. Investors who bought the rumor of a beat found the reality was already reflected in the stock's initial jump. The real question now shifts from the beat itself to whether the company's forward guidance can reset expectations higher.

The Fiber Engine: Exceeding Expectations on the Core Driver

The standout performer in the quarter was the fiber business, where AT&T not only beat expectations but also signaled a growth trajectory that may have been underappreciated. The company added 283,000 fiber subscribers in the fourth quarter, a number that topped analyst forecasts. This brought the total fiber subscriber base to more than 10.4 million, marking a significant milestone in its convergence strategy.

More importantly, the company's aggressive 2026 expansion plan suggests the growth story is just ramping up. AT&T announced it plans to expand its fiber footprint by 8 million locations in 2026, a move that would push its total passings to 40 million. This is a clear signal that management sees a large, untapped market ahead. The plan includes the pending Lumen acquisition and its Gigapower joint venture, aiming for a pace of about 5 million locations annually after 2026 to hit its 60 million passing goal by 2030. This kind of capital commitment points to a growth engine that could be larger than the market had priced in.

The financial impact of this subscriber growth is visible in the revenue line. Broadband revenue rose 6.7% year-over-year in the quarter, a key pillar of the company's push to bundle services. This increase, driven by the fiber subscriber gains, supports the core thesis that scaling the fiber network leads to higher-margin, bundled revenue and lower churn. While fixed wireless additions were a slight disappointment, the fiber beat and the massive expansion plan provide a clear path for future growth that the market may have been slow to recognize.

The Guidance Reset: Setting the Stage for 2026

The real test for AT&T's stock now moves from the past quarter to the future. Management's long-term outlook provides a positive signal, promising improved growth in Adjusted EBITDA and Adjusted EPS through 2028. This is a clear commitment to accelerating profitability, which the market will scrutinize for execution. The immediate focus, however, is on the 2026 plan.

For next year, the guidance sets a clear growth trajectory. Wireless service revenue is expected to improve in the low single digits, a modest but stable projection. The real engine is broadband, where the company projects growth in the mid-to-high teens. This aligns perfectly with the fiber subscriber beat and expansion plan, suggesting the market's initial skepticism about broadband growth may be unwarranted. The guidance effectively resets expectations higher for the core growth driver.

A critical pillar of the forward view is the shareholder return commitment. AT&T expects to return an additional $45 billion+ to shareholders from 2026-2028. That's a massive commitment, roughly three times the $12 billion returned in 2025. This level of capital return provides a significant floor for the stock, offering a tangible return even if the growth story unfolds slower than hoped. It signals confidence in the cash flow generation from its investment-led strategy.

The bottom line is that AT&T is attempting a full reset. The long-term outlook promises better profitability, the 2026 plan targets accelerating broadband growth, and the shareholder return pledge is substantial. The market's verdict will hinge on whether this guidance is ambitious but achievable, or if it sets up another expectation gap. For now, the setup is one of high commitment, leaving little room for error.

Catalysts and Risks: The Path Beyond the Beat

The market's initial relief after the Q4 beat has given way to a sharper focus on what's next. The path forward is defined by a clear catalyst and a notable risk, with the ultimate test being whether the company's ambitious fiber expansion can translate into the promised revenue growth.

The most significant near-term catalyst is the first-quarter closure of the Lumen fiber asset acquisition. This deal is a linchpin for the 2026 plan, directly contributing to the goal of adding 8 million locations this year. Integrating these assets smoothly will be critical. Success here would validate the strategic bet on convergence, accelerating the build-out of the bundled service platform that management believes reduces churn. The market will be watching for early signs of synergy realization and subscriber migration from legacy to fiber.

A more immediate headwind is the sequential slowdown in fixed wireless adds. The company added 221,000 fixed wireless customers in the quarter, down from a record 270,000 the prior quarter and below Wall Street's roughly 260,000 forecast. While management cited seasonality, the drop is a red flag for a growth segment that was supposed to be a key driver. It suggests competitive pressures or execution challenges in a nascent market, potentially diverting resources and attention from the fiber core. This weakness contrasts with the fiber beat and raises questions about the overall momentum of AT&T's broadband strategy.

The central tension now is between the company's massive expansion plan and its financial guidance. The plan calls for adding 8 million fiber locations in 2026, a pace that would require significant capital and operational execution. Yet the guidance for broadband revenue growth is set in the mid-to-high teens. The market will scrutinize whether this target is conservative, providing a safety net, or optimistic, setting up a potential miss if the subscriber ramp doesn't materialize as expected. The key will be whether the fiber subscriber growth trajectory-already showing a slight sequential dip-can accelerate to meet the capital-intensive build-out pace. If it can, the guidance reset will look prescient. If it falters, the expectation gap could reopen on the downside.
