BIO-UV Group S.A. (ALTUV.PA) fair value

ACCE thesis

BIO-UV Group makes water and air disinfection systems, including UV-C reactors used to sterilise drinking water, wastewater and process streams in industrial and municipal settings, so its core business sits in the pollution and treatment controls niche. Its 62.6% gross margin is the most interesting number on the sheet, since it suggests the equipment and consumables carry real pricing power even though operating margin has only reached 5.6%. Revenue growth of 2.1% is slow, and the 0.5% ROE means shareholders are earning almost nothing on their capital, so any case rests on margin expansion rather than volume. The forward P/E of 4.4 against a trailing 88.8 implies earnings are expected to rebound sharply, which is either a turnaround signal or a forecast that has yet to be tested, and a deeper look should start by checking which of those it is. With a market cap of roughly 12M EUR and no index membership, liquidity and disclosure will be thin, so the work is verifying the earnings recovery in the filings before anything else.
