AT&T Q1 2026 Financial Results Driven by Fiber and Wireless Growth

Key factors driving AT&T’s strong financial results in Q1 2026

AT&T’s management attributes its solid Q1 2026 performance primarily to continued momentum in its investment-led fiber and 5G strategy, the convergence of wireless + home Internet, and progress on cost/transformation initiatives, partially offset by ongoing decline in legacy businesses and the cash flow impact of higher fiber capex. ¹²

1) Strong growth in fiber + fixed wireless customer adds (core of service revenue improvement)

AT&T reported 584,000 total fiber and fixed wireless advanced Internet customer net additions in Q1 2026, described as its “best ever” first quarter result, and it was achieved alongside over 0.5 million consumer and business net adds for the sixth consecutive quarter. ¹
Management explicitly links its revenue growth to gains in fiber and fixed wireless Internet customers and to customer account growth in converged offerings. ²

2) Faster convergence with wireless (more “bundle” customers, better retention economics)

AT&T highlighted that 42% of advanced home Internet customers also choose AT&T Wireless, and excluding the Lumin transaction the organic convergence rate approached 45% in Q1. ¹
It also noted that this organic convergence rate was more than 3 percentage points higher year-over-year, calling it its fastest-ever YoY convergence growth. ¹

This matters financially because AT&T states that converged customers express stronger brand love, have higher Net Promoter Scores, and are expected to stay longer, improving churn and account growth trends over time. ¹³

3) Integration momentum and sales lift from the Lumin fiber acquisition

AT&T said it closed the Lumin transaction ahead of schedule, adding 1.1 million fiber customers and over 4 million fiber locations, and it is integrating those assets in major metro areas for faster growth. ⁴
Management reported early indicators that AT&T now offers fiber services “throughout” its distribution channels in those areas and that this has driven sales activity well above pre-transaction trends. ⁴
It also expects scaling engineering/construction/service delivery in those geographies in the back half of 2026 to support steady improvement in fiber and wireless customer growth. ⁴

4) Product and go-to-market actions increasing digital simplicity and “reasons to choose AT&T”

AT&T pointed to multiple customer-facing initiatives in Q1:

• Expanded the AT&T guarantee to cover Internet Air. ⁴
• Launched a new flagship app for a digital-first customer experience. ⁴
• Launched AT&T OneConnect, described as enabling customers to connect eligible devices without buying Internet access twice (single subscription for fiber + wireless). ⁴
• Refreshed Unlimited Your Way plans to deliver “more value.” ⁴

Management frames these moves as consistent with “simplicity, value and choice” for converged connectivity. ⁴

5) Revenue and EBITDA strength at the consolidated level (with service revenue growth improving fundamentals)

On reported results, AT&T said:

• Total revenues up 2.9% YoY in Q1. ²
• Service revenues up 1.4% YoY in Q1. ²
• Adjusted EBITDA up 2.3% YoY, while adjusted EBITDA margin decreased 30 bps to 37.4% (suggesting mix/cost headwinds despite top-line strength). ²

AT&T also emphasizes that growth is increasingly driven by fiber/fixed wireless gains and converged account growth. ²

6) Transformation/cost actions supporting EBITDA even as the business invests in growth

AT&T reported progress toward its $4 billion annual cost savings target by end of 2028, citing initiatives including:

• force optimization and federal rationalization
• efficiency gains from further AI enablement
• accelerated digitalization
• reductions in legacy operations/support costs ²

It also expects improved adjusted EBITDA growth in Q2 as comparisons normalize and as it implements further cost actions. ²

7) Free cash flow remains strong but declined due to higher fiber investment (important nuance)

AT&T reported free cash flow (FCF) of $2.5 billion, which was at the high end of its $2.0B–$2.5B outlook range given in January. ²
However, FCF declined by roughly $600 million vs. last year, driven primarily by higher capex of $5.1 billion as AT&T accelerated its fiber deployment pace. ²

So, the “strong financial results” appear to come from operating performance (revenues/EBITDA and customer metrics), while cash flow is temporarily pressured by the deliberate scale-up of fiber investment. ²

8) Advanced Connectivity business performance supports the consolidated results

Under AT&T’s segment framing (with most revenue and nearly all adjusted EBITDA in Advanced Connectivity), management said:

• Service revenues up 3.6% YoY in the quarter. ⁵
• Wireless service revenues grew 1.7% YoY, with growth driven primarily by customer base growth, including 294,000 postpaid phone net adds in Q1 (and postpaid phone ARPU flat). ⁵
• Advanced home Internet service revenues grew 27.3% YoY, with 2 months of revenues from Lumin-acquired geographies contributing about 650 bps to the reported growth rate. ⁶
• Advanced home Internet net adds were 512,000, including 273,000 fiber net adds and 239,000 Internet Air net adds (not counting the 1.1 million acquired customers from Lumin in early February). ⁶

AT&T also reported strong business connectivity momentum:

• Business advanced connectivity service revenues grew 7.2% YoY. ⁶
• Total Advanced Connectivity business service revenues were essentially flat YoY for the first time ever, reflecting improved fiber/5G growth offsetting declines in transitional services such as VPN. ⁷⁶

Bottom line

Across the excerpts, AT&T’s Q1 2026 “strong results” are driven by a coherent set of factors:

1. Customer traction in fiber and fixed wireless (584,000 advanced Internet net adds). ¹
2. Faster convergence of home Internet and wireless (organic convergence approaching 45%, fastest-ever YoY increase). ¹
3. Acquisition-driven scale and integration progress (Lumin closing ahead of schedule; distribution-channel sales lift). ⁴
4. Product/offer enhancements designed to simplify and increase the attractiveness of converged connectivity (Internet Air guarantee, OneConnect, plan refreshes). ⁴
5. Operating financial strength (revenues +2.9%, service revenues +1.4%, adjusted EBITDA +2.3%). ²
6. Ongoing cost and transformation actions supporting profitability trends even while capex rises. ²
7. A cash flow tradeoff: FCF remains at the top of guidance ($2.5B) but declines vs. last year due to higher fiber capex ($5.1B). ²

These elements together explain why AT&T could deliver solid operating results in Q1 while continuing to invest aggressively to scale fiber and converged customer relationships. ¹⁴²
