AT&T (T) Q4 2025 earnings review
Cash Flow Machine Turns on the Spigot
AT&T capped 2025 by meeting all financial targets and unveiling a massive capital return program. The headline is the 3-year outlook: $45B+ returned to shareholders through 2028, funded by surging Free Cash Flow (FCF) expected to hit $21B+ by 2028. Operationally, the 'Convergence' strategy (bundling Fiber + Wireless) is working, with Fiber revenue up 13.6%. However, cracks are appearing in Mobility churn (up 13 bps YoY), and the Legacy Business Wireline segment continues to evaporate.
🐂 Bull Case
With net debt-to-EBITDA projected to hit the 2.5x target range soon, AT&T is unleashing a $10B buyback authorization. They plan to repurchase ~$8B in stock in 2026 alone, alongside a steady $1.11 dividend.
Consumer Wireline is firing on all cylinders. Fiber revenue grew 13.6% YoY, and the company added 283k fiber subs. 42% of fiber households now bundle wireless, creating a sticky, high-value customer base.
🐻 Bear Case
Postpaid phone churn rose to 0.98% from 0.85% a year ago. While net adds (421k) remain positive, the rising churn indicates increased competitive intensity or consumer pressure that could erode margins if not checked.
The legacy business segment is in freefall. Revenues dropped 7.5% and operating income remains negative (-$163M). While AT&T is actively isolating these assets into a 'Legacy' reporting segment next quarter, they remain a drag on consolidated growth.
⚖️ Verdict: 🟢
Bullish. AT&T has successfully transitioned from a debt-laden utility to a cash-generating connectivity platform. The transparency of the new 'Advanced Connectivity' vs. 'Legacy' reporting structure, combined with a credible $18B+ FCF guide for 2026, makes the valuation compelling despite the wireless churn blip.
Key Themes
The Convergence Flywheel
This is the core of the bull thesis. 42% of AT&T Fiber households now subscribe to AT&T Wireless. These 'converged' customers are more profitable and stickier. The strategy is driving results: Consumer Wireline EBITDA margins expanded 320 basis points YoY to 38.4%.
Wireless Churn Normalizing Upward
After years of industry-leading low churn, AT&T is seeing a reversion. Postpaid phone churn hit 0.98%, up significantly from 0.85% in 24Q4. While ARPU held flat (-0.3%), the increased churn requires higher gross adds to maintain growth, potentially pressuring acquisition costs.
Radical Transparency: New Segment Reporting
Starting 26Q1, AT&T will report two main segments: 'Advanced Connectivity' (5G/Fiber, ~90% of revs) and 'Legacy' (Copper voice/DSL). This effectively ring-fences the dying copper business, allowing investors to value the growth engine (Advanced Connectivity) at a higher multiple while monitoring the managed decline of Legacy (guided to decline 20%+ in 2026).
Internet Air (Fixed Wireless) Scaling
AT&T Internet Air added 221,000 net subs in Q4, bringing the full-year total to 875,000 additions. This product is successfully capturing customers in areas where fiber hasn't reached yet or where copper is being decommissioned, preventing total customer loss to cable competitors.
Business Wireline Profitability
The Business Wireline segment continues to suffer. EBITDA margin remained compressed at 26.6% compared to Mobility's 54% service margin. With legacy services dropping 17.5% YoY, this segment is a melting ice cube that offsets gains elsewhere.
Other KPIs
Accelerating. Up 21% YoY from $0.43 in 24Q4. The growth was driven by lower operational costs and share count reduction, despite higher interest expenses.
Stable. Up 2.4% YoY. While growth has decelerated slightly from the ~3.5% range seen in previous quarters, it remains positive driven by subscriber volume rather than price (ARPU was essentially flat at -0.3%).
Improving. Down from $120.1B a year ago. The company expects net debt-to-Adjusted EBITDA to rise to ~3.2x temporarily due to Lumen/EchoStar acquisitions in early 2026, then de-lever back to 3.0x by year-end 2026.
Guidance
Accelerating. Implies ~6-11% growth over 2025's $2.12. The outlook anticipates acquisitions will be dilutive initially but accretive by 2028.
Accelerating. Up from $16.6B in 2025. This 8%+ growth underpins the capital return thesis. Note: This assumes cash tax benefits from recent legislation.
Stable. Consistent with the '3% or better' delivered in 2025. Growth in Advanced Connectivity is expected to offset the >20% decline in the new Legacy segment.
Accelerating significantly. Up from ~$4.3B in 2025. Management is aggressively returning capital now that the balance sheet is stabilized.
Key Questions
Wireless Churn Dynamics
Postpaid phone churn has risen to 0.98% from 0.85% a year ago. Is this purely a normalization of industry activity, or are you seeing specific competitive pressure in non-fiber markets? At what level does this become a concern for margins?
Advanced Connectivity Margins
As you separate 'Advanced Connectivity' from 'Legacy' in 2026, should we expect the Advanced segment to carry significantly higher EBITDA margins than the consolidated average? What is the long-term margin target for this specific segment once decoupled from copper costs?
Lumen/EchoStar Integration
You noted these acquisitions will be modestly dilutive to EPS in 2026-2027. Can you walk us through the specific integration costs or capex requirements causing this, and what is the milestone for turning accretive?
Legacy Segment Decline Pace
You guided Legacy revenue to decline 20%+ in 2026. Is there a scenario where this accelerates further, and does the negative EBITDA projected for this segment after 2027 risk dragging on consolidated FCF more than anticipated?
