STMicroelectronics ($STM): Two Hidden Monopolies and a Path to $20 Billion

Introduction

Look at where the next decade is being built, and you keep bumping into the same company without realizing it.

The satellites stitching the internet across the planet run on its chips. The AI data centers ripping out copper and replacing it with light to feed their GPUs are buying its optical silicon. The devices around you are filled with on-board intelligence running on their processors. The electric car replacing the gas one is packed with its power chips and its sensors. Four of the largest build-outs of the decade, and one chipmaker is threaded through every one of them.

Almost nobody thinks of it this way. The market still files STMicroelectronics under “European auto and industrial chips,” a commodity name to trade around the cycle and forget. That filing is the opportunity because the gap between how it is priced and what it is becoming is enormous.

Underneath the dull label sit two businesses that behave like monopolies. One controls more than 90% of a market growing over 30% a year, which you have never once heard ST mentioned in. The other is a fortress nobody can dislodge, quietly throwing off strong margins while drawing almost no attention. The stock pays for neither of them today.

Then there are the partners. Amazon tied its own equity to a multi-year deal. Nvidia is co-designing with it. SpaceX has built alongside it for a decade. Those are not logos that a commodity chipmaker collects.

And the prize is large. Management has drawn a path from roughly $12 billion in revenue at a 2% operating margin today, to $20 billion at a 30% margin by the end of the decade. Reach even the middle of that, and the earnings are several times what the current price reflects.

This is the full breakdown: the four engines and which two truly matter, the markets underneath them, the one number that unlocks everything, and where we think the stock can go from here.
