Final Rating:

• Economic Moat Strength: Wide
• Moat Trend: Widening

AT&T is positioned to sustain >4% EBITDA growth and 7–10% FCF CAGR through 2030, driven by its convergence leadership and infrastructure moat.

What are the key risks to AT&T's economic moat?

AT&T faces several risks that could erode its competitive advantages:

1. Cable MVNO Competition:

   • Companies like Comcast (Xfinity Mobile) and Charter (Spectrum Mobile) are gaining traction in wireless through low-cost mobile-virtual-network-operator (MVNO) models. They added 500K+ subs/quarter in 2024, leveraging existing broadband relationships.
   • While AT&T’s postpaid phone ARPU ($54.76) remains 15% higher than cable MVNOs, price-sensitive customers may migrate to cheaper alternatives.

2. Regulatory and Subsidy Uncertainty:

   • The fragmented execution of the $42.5B BEAD program could delay rural fiber ROI and increase administrative costs.
   • Sunsetting of the Affordable Connectivity Program (ACP) might impact retention of 3.5M+ subsidized subscribers.

3. Labor and CapEx Inflation:

   • Fiber deployment costs rose 10–15% in 2024 due to labor shortages and equipment inflation. AT&T’s $24B annual CapEx faces margin pressure despite long-term vendor contracts.

4. Technological Disruption:

   • Fixed Wireless Access (FWA) adoption (e.g., T-Mobile’s 5G Home Internet) threatens broadband market share in non-fiber areas. AT&T’s FWA subs (1.2M) lag behind T-Mobile’s 4.8M.

5. Debt Management:

   • While net debt/EBITDA improved to 2.7x (2024), rising interest rates could increase refinancing costs for $128B gross debt.

How does AT&T's fiber strategy compare to competitors?

AT&T’s fiber strategy is differentiated by scale, convergence, and asset-light partnerships:

Strategic Advantages:

1. Owned Infrastructure: Unlike T-Mobile (wholesale) or Comcast (HFC), AT&T controls end-to-end fiber and 5G networks, enabling seamless convergence.
2. Asset-Light Growth: Partnerships with GigaPower and regional ISPs allow expansion into 1.5M+ new locations without full CapEx burden.
3. Monetization: Fiber ARPU is 20% higher than legacy DSL, and bundling drives wireless postpaid phone net adds (419K in Q2 2024).

Weaknesses vs. Peers:

• Slower rural deployment than Frontier Communications’ 10Gbps fiber push.
• Limited FWA scale compared to T-Mobile’s 5G Home Internet.

What factors contribute to AT&T's customer retention rates?

AT&T’s industry-leading postpaid phone churn (0.72% in Q2 2024) stems from:

1. Network Quality and Reliability:

   • #1 Ranked Fiber Network: Ookla’s 2024 award for fastest U.S. internet (216 Mbps median speed).
   • FirstNet Authority: Exclusive 20-year contract with U.S. first responders, ensuring network priority and reliability.

2. Converged Discounts:

   • Bundled wireless + fiber saves customers $20/month, driving 40% cross-penetration in fiber markets.
   • Converged households exhibit 25% lower churn than single-service users.

3. Proactive Customer Assurance:

   • AT&T Guarantee: Dependable connectivity, price locks, and service credits for outages (introduced in 2025).
   • 24/7 customer care with AI-driven issue resolution (30% faster response times).

4. Exclusive Perks:

   • Free HBO Max (for eligible plans) and premium international roaming features.
   • Business-tier security tools (e.g., AT&T Dynamic Defense) for SMB customers.

5. Loyalty Programs:

   • AT&T Thanks: Reward points for bill credits, device discounts, and VIP experiences.
   • Targeted retention offers for high-value subscribers (e.g., $200 loyalty credit).

Impact on Financials:

• Converged customers generate $1,200+ higher lifetime value than single-service users.
• Retention efficiency saves $400M annually in avoided acquisition costs.

This multi-pronged approach positions AT&T to sustain churn leadership despite market saturation.
