This paper reframes Economic Value Added (EVA) from a supplementary performance metric into the primary engine of corporate valuation. Contrary to conventional discounted cash-flow (DCF) methodologies-which treat cash flows as the origin of value-this study demonstrates that cash flows are derivative representations of underlying operating economics. By grounding valuation in operating returns on invested capital and explicitly modeling the cost of capital as an economic burden, the paper establishes EVA as the causal mechanism through which value is created or destroyed. Discounted cash flows emerge as algebraic transformations of economic profit rather than independent sources of value. The framework resolves apparent valuation discrepancies as timing artifacts and provides structural closure through convergence across independent valuation paths.
