DCF Valuation

Purpose

Discounted cash flow valuation with WACC calculation, free cash flow projection, terminal value estimation, sensitivity analysis, and enterprise-to-equity value bridge.

Routing

Use when: Use when the user asks about discounted cash flow valuation, intrinsic value estimation, WACC calculation, terminal value, enterprise value, equity value bridge, or company valuation using projected cash flows.
Do not use when: Do not use when the request is about relative valuation only (comparable companies/transactions), portfolio optimization, or non-valuation financial analysis.
Outputs: Outcome from DCF Valuation: complete DCF model with FCF projections, WACC derivation, terminal value, sensitivity tables, and per-share equity value.
Success criteria: Returns a fully built DCF with all intermediate calculations, clearly stated assumptions, sensitivity analysis, and an enterprise-to-equity bridge with per-share value.
