Long Book Analysis
Aixtron SE
Coming from the compound-semiconductor sector, AIXTRON represents a long position in Kerrisdale's portfolio. The manager’s opinion is that it is an unappreciated asset that is a crucial element in the semiconductor industry. It has a capitalisation of $2.2 billion and has drawn limited attention from investors. A dominant position in the metal-organic chemical vapor deposition tool sector serves as a core strength. These tools are essential for the production of compound semiconductors that allow increased performances including power, efficiency, and thermal tolerance.
With a 70%-90% market share comes from decades of understanding of the processes, unique tool design, and close cooperation with the scientific community. Factoring these down makes Aixtron tools almost impossible to duplicate.
