AIXTRON SE

Germany · Xetra: AIXA.DE · Market cap: $4.27B · P/E: 47.3 · P/S: 7.1

AIXTRON builds the machines that lay down ultra-thin layers of material used to make chips, LEDs, and other electronic devices.

AIXTRON builds the ovens of the chip world. Not the ovens that bake bread — the ones that grow microscopic layers of crystal, one atomic layer at a time, onto a flat wafer. Those layers become the light-emitting part of an LED, the power-handling part of an electric car's chip, or the tiny lasers that beam data through fiber-optic cables. Chipmakers buy these machines, called deposition tools, because you cannot make a modern electronic device without them.

AIXTRON's MOCVD tools grow crystal layers that make LED and laser chips.

The business is simple in concept and brutal in practice. AIXTRON sells a fairly small number of very expensive machines each year, so revenue swings hard with the mood of the chip industry. When chipmakers are confident, they order tools; when they are nervous, they stop. That whiplash is the core risk. The company, based in Herzogenrath, Germany, competes mainly with Veeco Instruments and a handful of others in this niche, and it has spent years fighting to stay ahead on the technology that chipmakers need next. Its biggest growth bet is silicon carbide, a material that makes power chips far more efficient than traditional silicon. Those chips matter for electric vehicles, solar inverters, and fast chargers — anything that has to handle serious current without wasting it as heat. AIXTRON sells the tools that coat silicon carbide wafers, and demand for those tools has become a major driver of its results. It also serves the LED and laser markets, which are more mature and cyclical.


The company's fortunes rise and fall with its customers' capital spending plans, which is why its order book matters more than almost anything else. AIXTRON has kept a strong balance sheet and returned cash to shareholders through dividends and buybacks, but the honest summary is this: it makes excellent, hard-to-build machines for a market that can turn cold fast. Great technology, lumpy revenue, and a customer base that decides its fate one big purchase order at a time.
