STO3.DE (hold): Cyclical bet on German construction, currently in a deep downturn: revenue fell from €1.72bn to €1.59bn and operating margin from ~8% to 4.02%, taking ROIC to 6.37%, below cost of capital and probably destroying value per the author; facade insulation/render is commodity-adjacent and sold into a subsidy-sensitive market where German energy-efficiency retrofit policy can switch demand on or off by regulation. Capital allocation called prudent and balance sheet rock solid, though author notes quality may deteriorate fast in a cyclical industry; over five years the company generated €563m CFO, reinvested 38% (€216m capex), spent €86m on acquisitions and securities (~€66m securities), paid 26% as dividends, and cut debt by €132m (23% of CFO). At ~€600m market cap the author values it at 0.79x book, 3.5x EV/EBITDA, with €159m net cash (27% of market cap), implying ~€441m for a business that produced €94.5m even in a bad year; on 7% normalized operating margin the author estimates €111m EBIT, €78m net profit at 30% tax, and 7.7x normalized P/E. Author frames current trough as cyclical, not a broken business (margins ran near 7% pre-downturn), and views demand as regulatory/structural — Europe's building stock must be insulated to meet energy-efficiency targets — deferred by weak construction rather than destroyed.
