AT&T Stock Drops 6.45% Despite Earnings Beat: Buy the Dip?

AT&T (T) reported third-quarter results that beat analyst estimates for both adjusted earnings per share and revenue. The company also raised its 2026 profit outlook and maintained its free-cash-flow targets. Notably, AT&T achieved record internet net additions and added more than one million advanced connectivity customers for the second consecutive quarter, showcasing the strength of its fiber offerings.

Despite these positive results, AT&T's stock closed at $21.91, down 6.45%, on unusually high volume of 82.7 million shares, well above its three-month average of 45.9 million shares. The decline came as investors focused on higher spending requirements and growing competition from SpaceX.

SpaceX, led by Elon Musk, recently struck a nationwide low-band spectrum deal with Grain Management, marking a significant step toward offering direct-to-device phone coverage across the U.S. This development threatens traditional telecom carriers like AT&T.

Additionally, AT&T agreed to sell its Mexico wireless unit for $2 billion in cash on Oct. 13, sharpening its focus on the U.S. market. The company filed the Mexico-sale 8-K earlier this month, keeping the divestiture on investors' radar.

Sector peers also felt the pressure: Verizon (VZ) fell 2.20% and T-Mobile (TMUS) dropped 2.54%, reflecting broader concerns about competitive threats and spending pressures in the telecom industry.

The market's negative reaction to AT&T's earnings beat highlights investor concerns about the company's capital spending needs. While fiber growth is strong, it requires significant investment, and investors are wary of the impact on free cash flow and profitability.

The SpaceX threat is particularly unsettling. SpaceX's low-band spectrum deal could enable direct-to-device satellite coverage, potentially disrupting traditional wireless carriers. Although the technology is still emerging, it represents a long-term risk to AT&T's core business.

AT&T's decision to sell its Mexico wireless unit for $2 billion is a double-edged sword. On one hand, it simplifies operations and allows the company to focus on its U.S. business; on the other, it raises questions about growth prospects and capital allocation.

The stock's decline also dragged down peers Verizon and T-Mobile, indicating that investors are reassessing the entire telecom sector. The high trading volume suggests that institutional investors are actively repositioning their holdings.

Looking ahead, AT&T's ability to balance growth investments with cash flow generation will be crucial. The raised 2026 profit outlook is a positive sign, but execution risks remain.
