The estimated intrinsic value of Companhia de Saneamento Básico do Estado de São Paulo - SABESP (SBS) using a Dividend Discount Model (DDM) is $19.31 (based on the recommended DDM method), compared to the current stock price of $33.80. This suggests the stock may be overvalued by 42.9% relative to its intrinsic value.

For utility companies, which are valued primarily for their stable and predictable dividend streams, SharesGrow uses a Dividend Discount Model (DDM): Intrinsic Value = Annual Dividend ÷ (Cost of Equity − Dividend Growth Rate). This model assumes a long-term dividend growth rate of 4% — consistent with the historical average for regulated utilities — and uses a minimum 7% cost of equity. The DDM is the preferred valuation method for income-oriented stocks with stable payout histories.

The valuation uses a CAPM-derived discount rate of 4.09% (CAPM-derived from beta of 0.20). For comparison, the standard 20-year DCF model produces: Operating Cash Flow (OCF): $54.10 | Free Cash Flow (FCF): $52.28 | Net Income (NI): $54.62.
