Latest financial snapshot
Financial summary
AT&T
AT&T's financial story is large revenue, large debt and a slow correction. The company funded the $48.5 billion DirecTV purchase in 2015 and the $85.4 billion Time Warner purchase in 2018 largely with borrowing, and net debt passed $180 billion after Time Warner closed. It then reversed course: WarnerMedia was separated in 2022, the dividend was cut, and the remaining 70% DIRECTV stake went to TPG in July 2025 for a $5.6 billion gain. FY2025 revenue was $125.6 billion, with $23.4 billion of total net income, $46.4 billion of adjusted EBITDA and $16.6 billion of free cash flow against $117.4 billion of net debt. Roughly $22 billion a year of capital investment goes mostly into fiber and 5G.
IBM
IBM's reported revenue fell from about $80 billion in 2016-2018 to $57.4 billion in 2021, mostly because the Kyndryl spin-off and earlier divestitures removed low-margin services. Since then the slimmer company has grown each year: $60.5 billion in 2022, $61.9 billion in 2023, $62.8 billion in 2024, and $67.5 billion in 2025 (up 7.6%). FY2025 net income from continuing operations was $10.6 billion and free cash flow was $14.7 billion. In Q2 2026, revenue rose 1% to $17.16 billion: software grew 5% to $7.76 billion, consulting was flat at $5.33 billion, and infrastructure fell 7% to $3.84 billion as IBM Z sales lapped the z17 launch. Some large software deals slipped out of the quarter, so IBM cut its 2026 constant-currency revenue growth forecast to 4-5% while keeping its target of about $1 billion more free cash flow than in 2025.

Business model and strategy
AT&T
How it makes money
AT&T runs a capital-intensive network business. It buys licensed wireless spectrum, builds and upgrades cell sites, and trenches fiber, then charges consumers and businesses a monthly fee to use that network. Capital investment was $22.0 billion in 2025 against $125.6 billion of revenue.
Growth strategy
With the US smartphone market saturated, AT&T's growth depends on home internet and on keeping the wireless customers it has. It is building fiber, which passed 32.0 million consumer and business locations at the end of 2025 and carried 10.4 million subscribers, and it sells AT&T Internet Air fixed wireless where fiber is not available.
Competitive advantage
AT&T's advantage is the cost of replicating what it already owns. Its fiber network passed 32.0 million consumer and business locations at the end of 2025, and its mid-band 5G service covers more than 310 million people. Keeping that going took $22.0 billion of capital investment in 2025 alone, which is why the national market has three carriers rather than thirty.
IBM
How it makes money
IBM makes money from four segments. Software ($29.96 billion in FY2025, about 44% of revenue) includes Red Hat Enterprise Linux and OpenShift, HashiCorp Terraform and Vault, Confluent data streaming (from March 2026), watsonx AI, automation, security, and mainframe transaction-processing software, sold mostly as subscriptions and recurring licenses.
Growth strategy
IBM does not try to beat AWS, Microsoft Azure, or Google Cloud at selling public cloud capacity. It sells the software layer that runs across all of them and across on-premises data centers.
Competitive advantage
IBM's main advantage is how deeply it is built into the core systems of large regulated organizations. Banks, card networks, insurers, and governments run high-volume transaction processing on IBM Z, and moving those workloads is slow, risky, and expensive.
