Executive Summary
Every advanced computer chip is made inside a vacuum, in factories where a single speck of contamination can ruin an entire batch. Controlling that vacuum, opening and sealing chambers thousands of times with total reliability, is the job of a specialised valve, and one company makes most of them. VAT Group, based in the Swiss village of Haag, holds roughly a 70% share of the market for semiconductor vacuum valves, many times larger than its nearest rival. Its components sit inside the etching, deposition and lithography tools used by every leading chipmaker, from TSMC to Samsung, making VAT a classic "pick-and-shovel" supplier to the entire industry.
What makes the business compelling now is the scale of the spending wave it feeds on. The build-out of AI data centres has triggered record investment in chip factories, and the newest chip designs need far more vacuum steps than before, lifting the value of VAT's content in every tool. Alongside a fast-growing service business and one of the strongest cash-flow records in European industrials, that gives VAT a rare mix of dominance, structural growth and quality. The main question for investors is not whether the business is excellent, but whether its premium share price already reflects it.

A Near-Monopoly at the Heart of Chipmaking
VAT's position is about as close to a monopoly as exists in the equipment that builds semiconductors. It holds around 70% of the market for vacuum valves used in chip manufacturing, a lead of roughly eight to ten times over its closest competitor. Crucially, VAT wins its business at the design stage, being specified into a customer's tool years before a factory is even built, which locks in revenue for the life of that equipment. In 2025 the company recorded 150 of these design wins, a new record, roughly half of them on the most advanced chip nodes. This is engineering trust, not a commodity part, and it is very hard to displace.
Geared to the AI-Driven Semiconductor Boom
The spending needed to make AI chips is surging, and VAT is unusually exposed to the parts of it that matter most. Industry body SEMI expects 300mm fab equipment spending to keep growing at double digits into 2027, driven by AI logic chips and high-bandwidth memory. The newest chip architecture, known as gate-all-around, requires many more vacuum-based process steps per wafer than older designs, so each generation of chip lifts the amount of VAT content inside every tool. Because vacuum-intensive steps such as etching and deposition are growing faster than the overall equipment market, VAT should grow faster than the industry it serves.
A High-Quality Cash Machine With a Growing Service Engine
Beyond the growth story, VAT is a genuinely high-quality business. In 2025 it generated record free cash flow of CHF 230m, converting profit into cash at an exceptional rate, and raised its dividend 12% to CHF 7.00 per share. Its installed base of around three million valves, which management aims to double by 2030, throws off recurring demand for spare parts, consumables and upgrades as customers run their factories flat out. This Global Service arm is higher-margin and steadier than selling new valves, and it grows every time a chip factory is running near full capacity, which most now are.
Catalysts
The key events that could drive investment opportunities and shift markets.
Half-year 2026 results (due 22 July): confirmation that delayed first-quarter shipments have converted to sales would reassure the market.
Order momentum: a book-to-bill ratio comfortably above one would show the demand ramp is broadening, not stalling.
Leading-edge node ramps: as 2nm and gate-all-around chips move into volume production, VAT's content per tool steps up.
Service growth: high factory utilisation should keep driving higher-margin spare-part and upgrade demand.
A structural spending supercycle: SEMI and others see chip-equipment spending climbing for years on AI demand.
Adjacent markets: applying VAT's vacuum expertise to displays, solar and advanced energy could widen its addressable market.
Key Risks
Key pieces of information about the business risks that you need to know about.
A Premium Valuation With Little Room for Error
VAT trades on a demanding valuation, at times above 30 times forward earnings, having roughly tripled from its 2024 lows to reach record highs around CHF 686 in mid-2026. A rating like that assumes years of strong growth will arrive on schedule. The danger is that even good results can disappoint if expectations are set higher still. When VAT reported record 2025 figures, the shares fell in a "sell the news" reaction, and its valve segment briefly lagged in early 2026. At this price, any quarterly wobble in margins or product mix can trigger sharp share-price falls.
A Cyclical Industry Prone to Sharp Swings
Chip-equipment demand moves in waves, and VAT rides every one of them. When chipmakers pause or cut their factory spending, orders for new valves can drop quickly, as they did during the 2023-2024 downturn. The current upcycle is powered heavily by AI investment and leading-edge logic, so a slowdown in either would remove a key support. Older memory chip investment, in particular traditional NAND flash, has been slow to recover, leaving VAT more reliant on a narrower set of demand drivers than the strong headline numbers suggest.
Currency and China Exposure Add Uncertainty
VAT manufactures largely in Switzerland but sells worldwide, so a strong Swiss franc directly squeezes reported profits. Currency swings turned its net finance result negative in 2025 and remain a stated drag on 2026 margins. Separately, China is a major market for VAT, and any tightening of US export controls or a cooling of Chinese factory investment would feed through to orders with only a short delay. These are risks the company can manage but cannot control, and both can move results independently of underlying demand.

Along those lines (and likely never cheap either), consider industrial champion VAT Group. Likely one of widest moats globally. Supplier to semiconductor industry. 80% market share of vacuum valves. Moat case similar to WD-40 (read Bruce Greenwald’s “Value Investing” for best explanation). Basically clients won’t switch to lower product to save $2000-5000 on a $50m semi fab. It won’t happen. They have endless pricing power.

Demand for vacuum valves (such as produced by VAT Group and MKS Incorporated) from the semiconductor supply chain will a) increase a lot (very likely), b) more than expectations (perhaps). Does (b) needs to happen for stocks to do well? I'm not so sure

So VAT Group had a cool demo subcomponent. A chamber that brings the wafer to vaccum is milled out of 1 piece of metal Asked them about a competitor, and they basically called it crap cuz casted metal The flow of gas/creation of vaccum impeded by micro pores in cast metal

What the Pros are asking
Here are the questions that professional investors are asking before making an investment decision.
Is the valuation justified, or has the good news been priced in?
This is the core debate. Supporters argue that a business with 70% market share, record cash generation and a multi-year demand tailwind deserves a premium, and note the shares still sit below their five-year average multiple on some forecasts. Sceptics counter that at more than 30 times earnings, VAT is priced for near-perfect execution, leaving little cushion if any quarter disappoints. The honest position is that both can be true: the quality is not in doubt, but the entry price determines how much of the upside remains, and the shares can be volatile around results.
How durable is the current demand wave?
VAT frames the market as entering a structural growth phase rather than a normal cyclical bounce, pointing to AI infrastructure spending and more than 110 chip factories under construction worldwide. Bulls see years of rising equipment budgets ahead. More cautious observers remember how quickly the last cycle turned in 2023 and note that much of today's strength rests on AI and leading-edge logic. The evidence that matters is order intake and book-to-bill: VAT's near-record first-quarter 2026 orders suggest the ramp is real, but investors will watch closely for any sign it is a one-off spike.
Can VAT keep its dominant market share?
VAT's roughly 70% share is the foundation of the whole investment case, so any erosion would matter enormously. The bull view is that switching valve suppliers mid-programme is costly and risky for a chipmaker, and that VAT's habit of designing itself into tools years ahead creates a durable moat. The bear view is that market shares this high can only fall, and that well-funded rivals or in-house alternatives could nibble at the edges over time. So far the record of design wins suggests the moat is holding, but it is a metric worth tracking every year.
How exposed is the business to geopolitics and China?
China is one of VAT's largest markets, which cuts both ways. Continued Chinese investment in domestic chip capacity has supported orders, but a tightening of US export restrictions or a policy-driven slowdown could hit revenue with only a short lag. Management points to a globally diversified manufacturing footprint and a flexible operating model as buffers. The realistic view is that VAT is more insulated than a pure China play, yet still enough exposed that a sharp escalation in trade tensions would be felt in its order book.
What separates upside from disappointment over the next two years?
Two things. First, delivery: VAT is hiring hundreds of staff and ramping capacity to meet demand, and margins depend on turning a full order book into shipped product without stumbles. Currency and elevated research spending are near-term drags that need volume growth to offset. Second, the shape of the cycle: sustained order growth would validate the premium rating, while a stall would expose it. In short, the debate is less about whether VAT is a great company and more about whether execution and the cycle match the high expectations already in the price.
