Cia de Saneamento Basico do Estado de Sao Paulo (SABESP)

“SABESP is a legal monopoly over water and sewage for 22 million people in Brazil's wealthiest state, trading at 0.54x book with 21% ROE and a contractually mandated R$84B capex reinvestment runway through 2030 — the FCF-negative investment phase through ~2029 is masking a fundamentally strengthening regulated asset base, and the post-privatization governance step-change under Equatorial's operational control has materially de-risked the historically dominant political tariff risk; at 12x forward earnings, the market is pricing in Brazil risk but not the compounding potential of a regulated monopoly whose investment returns are embedded in a 36-year concession framework.”
