VAT Group makes the ultra-clean valves that open and close the vacuum chambers where computer chips and flat screens are manufactured.
VAT Group makes the heavy-duty doors of the modern factory. In chip fabs and display plants, products are built inside sealed chambers where even a speck of dust or a whiff of air can ruin the work. VAT makes the vacuum valves that open and close those chambers billions of times, letting wafers and glass panels move in and out while keeping the inside pure. Its customers are the equipment makers who build chip and display production lines, plus solar, industrial and research users — and the valve is often a small part of a very expensive machine, which means customers care more about reliability than price.
Here is the key to the business: a valve that fails can shut down a fab worth billions. The machine makers who buy from VAT, such as Applied Materials, ASML, Lam Research and Tokyo Electron, sell tools that cost tens of millions of dollars each and run nonstop. So they pay up for valves that work every single time. That gives VAT real pricing power and sticky relationships, because switching suppliers means re-qualifying a part inside a machine that customers depend on. The company is based in eastern Switzerland and competes with other valve makers, but it has built a leading position in this niche over decades. The business runs on the chip industry's boom-and-bust cycle. When chipmakers build new fabs, demand for valves surges; when they pause, orders soften. VAT has ridden that wave hard in recent years, with revenue jumping as the world raced to build semiconductor capacity, and the company pours cash into expanding its own factories to keep up. Its valves also show up in markets beyond chips, like displays and solar, but semiconductors are the engine. That is both the strength and the risk: great when fabs are being built, painful when they are not.
There is a quiet charm in a company like this. It does not make the chips, the machines, or the software — it makes the tiny, precise piece that lets all of it happen in a vacuum. Most people have never heard of VAT Group, yet almost every advanced electronic device they own passed through one of its valves on the way to being made. It is a pick-and-shovel business in the truest sense, selling the unglamorous hardware that the glamorous industry cannot run without.
