Maxim: The Competitor It BoughtNarrow moat

Analog Devices (ADI) — moat facet

ADI named Maxim as a competitor in 2019 and 2020 and bought it in 2021 for $28 billion; its 10-K has named no competitors since 2022.

One way to handle a competitor is to own it, and ADI's filings record the moment it did. The fiscal 2019 and 2020 10-Ks listed seven competitors by name: Broadcom, Monolithic Power Systems, Infineon, NXP, Maxim Integrated, Texas Instruments and Microchip12. In August 2021 Maxim became part of ADI3.

A named list of seven, then nine, then none.

The fiscal 2021 10-K, written after the deal, named nine instead, with Maxim gone and Qorvo, STMicroelectronics and Xilinx added4. From fiscal 2022 the list disappeared. The fiscal 2025 10-K says only: "We compete with a number of semiconductor companies in markets that are highly competitive."5

What the purchase bought, in competitive terms, was a rival's sockets; ADI said the combination created "an expanded suite of top-performing mixed-signal and power management technology offerings"6. The effect is clearest in automotive. ADI's automotive revenue was $1,248.2 million in fiscal 20217 and $2,407.8 million in 20228; it was $3,277.9 million in fiscal 20259. A socket that Maxim had won was now an ADI socket, and a customer that had used both suppliers to keep prices honest had one fewer choice.

That is a real gain and an expensive one. The price was about $28.0 billion of ADI stock10, and the return on invested capital has been between 4.3% and 7.7% in every year since11. Removing a competitor is worth a great deal only if the combined company can charge more or spend less than the two did apart.

The deal's competitive value shows up in automotive. If automotive's share of revenue falls below 20% for a full year, from 29.7% in fiscal 202512, the position bought from Maxim will have been diluted by faster growth elsewhere or eroded by the rivals still competing for those sockets.

Moat trajectory: Holding steady

Automotive 29.7% of FY2025 revenue; 24.8% in Q3 FY2026.

The weight of the position bought from Maxim; below 20% for a full year would say it is fading.
