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.
BYD
BYD's revenue grew more than fivefold in five years, from ~$21.8 billion (CN¥156.6 billion) in 2020 to ~$112 billion (CN¥803.96 billion) in 2025, as its new energy vehicle sales rose to 4.6 million units. Profit peaked in 2024 at about $5.59 billion (CN¥40.2 billion) and fell 19% in 2025 to ~$4.53 billion (CN¥32.62 billion) attributable to shareholders, BYD's first annual decline in four years, which the company linked to product mix changes and a lower gross margin. Gross margin slipped from 19.1% in 2024 to 17.5% in 2025. The first half of 2026 brought revenue of ~$47.9 billion (CN¥344.8 billion) (down 7.1%) and net profit of ~$1.71 billion (CN¥12.3 billion) (down 20.5%), although second-quarter profit rose year on year for the first time in five quarters on record exports. Overseas revenue of ~$25.2 billion (CN¥181.3 billion) overtook revenue from China for the first time.

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.
BYD
How it makes money
BYD earns most of its revenue by designing, building and selling passenger cars under the BYD (Dynasty and Ocean series), Denza, Fangchengbao and Yangwang brands, along with buses, trucks, batteries and energy storage systems. Its automobiles and related products segment produced ~$90.2 billion (CN¥648.6 billion) in FY2025, about 81% of group revenue.
Growth strategy
BYD's growth plan has three parts. First, build locally abroad: plants in Thailand, Uzbekistan and Camaçari, Brazil are producing cars, Hungary is due to start series production in the fourth quarter of 2026, and a Turkish plant was paused in June 2026 while BYD concentrates on Europe. Second, move upmarket through Denza, Fangchengbao and Yangwang, which sell at higher prices than core BYD models.
Competitive advantage
BYD's advantage is cost control from owning its supply chain. It makes its own LFP Blade battery cells, motors, electronic controls and power chips, so it can sell a Seagull hatchback from around CN¥70,000 in China and still run a profitable car business, and it can put new technology such as the second-generation Blade Battery and FLASH charging into many models at once.
