Financial profitability (rentabilité financière) measures the return generated for shareholders on the equity they have invested: ROE (Return on Equity) = Net Income / Shareholders' Equity. It is influenced by both operating profitability (ROCE) and financial leverage, as described by the DuPont decomposition: ROE = ROCE + (ROCE - Cost of debt) × Net debt/Equity. In business valuation, financial profitability above the cost of equity indicates value creation for shareholders; below this threshold, it signals value destruction. Comparative analysis against sector peers identifies whether a company's profitability is structurally superior or reflects temporary leverage effects.

‍

Example: a Swiss company presents a ROE of 18% (net income CHF 1.8 million / equity CHF 10.0 million). DuPont decomposition: ROCE = 12%, financial leverage contribution = 6% (from 40% gearing at cost of debt of 4.5%). The leverage-adjusted component confirms that 6 of the 18 ROE percentage points derive from leverage — not from operational outperformance — an important distinction for assessing sustainable value creation.
