FM Mattsson AB (publ) (FMM-B.ST) fair value

ACCE thesis

FM Mattsson makes pipes and fittings in Sweden, with a manufacturing base that serves the water, heating and infrastructure networks where the product lives for decades. The moat is less a brand than the installed base and the approval and specification lock-in that comes with building codes and municipal utility standards, which makes a replacement sale hard to win on price alone. Revenue grew 10.2% and the gross margin sits at 39.5%, so the pricing power appears to be real, though the company is small and its shares are thinly traded, so catalysts are harder to identify from outside the register. The 30.9x trailing multiple and 16.3% return on equity are a rich price for a business of this scale, so the question for a deeper look is whether the 14.7% operating margin can keep widening through a construction cycle that has been soft across Europe.
