Latest financial snapshot
Financial summary
Amphenol
Amphenol compounds through acquisition in a fragmented industry. Net sales rose from $12.55 billion in 2023 to $15.22 billion in 2024 and $23.09 billion in 2025, and net income rose from $1.93 billion to $2.42 billion and then $4.27 billion across the same three years. Fiscal 2025 produced a 25.4% GAAP operating margin, $5.4 billion of operating cash flow and $4.4 billion of free cash flow, and the company returned nearly $1.5 billion to shareholders while completing five acquisitions. The pattern is consistent: buy niche connector, cable and sensor makers, leave their management and brands in place, add purchasing scale, and fund the next deal from cash flow and investment grade debt.
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.

Business model and strategy
Amphenol
How it makes money
The business model is high volume, highly specialized B2B component manufacturing. Amphenol sells hundreds of thousands of connector, cable, antenna and sensor variants to thousands of customers, and no single end market dominates: in 2025, data centers and information technology accounted for 36% of sales, industrial 19%, automotive 15%, communications networks 10%, defense 9%, mobile devices 6% and commercial aeros…
Growth strategy
Amphenol's growth strategy has two parts: sell into secular demand and buy specialized suppliers. On the first, it builds high speed copper and optical interconnects for AI clusters, including the Celerity mezzanine connector family rated to 224 Gb/s PAM4 and XtremePass co-packaged copper interconnects aimed at 448G class links, plus high voltage connectors and sensors for electric vehicles, which carry more wiring a…
Competitive advantage
Amphenol's competitive advantage rests on switching costs and the cost of failure. A connector may cost a few cents, but if it fails the aircraft, satellite or server rack around it stops working, so buyers qualify suppliers rather than shop on price.
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.
