The WACC of 5.94% is derived from a 4.30% risk‑free rate, a 0.61 beta applied to the 3.01% market risk premium, and a 1.51% BAA spread, producing a relatively low discount rate that inflates the present value of future cash flows.
A sensitivity check shows that a 0.5% increase in WACC reduces the intrinsic value by roughly 8%, underscoring how pivotal the cost‑of‑capital input is to the DCF outcome.
Free‑cash‑flow growth is anchored at a modest 2.3% CAGR over ten years; applying this to historical cash‑flow trends yields a share value of $575.25, implying a 144.7% upside versus the current market price.
The analyst‑driven DCF assumes a higher terminal growth rate (approximately 4% versus 2% in the historical model), pushing the per‑share estimate to $793.39 and a 237.5% upside, highlighting the sensitivity of the terminal value to growth assumptions.
Terminal value accounts for about 60% of the total DCF, meaning that any deviation in the perpetual growth rate will disproportionately affect the valuation.
The model uses FCFF discounted at WACC, which is appropriate for an integrated refiner like Valero because it captures both operating performance and capital‑structure effects.
