The buyer's investment banker is using a discounted future earnings model but has applied an inflated discount rate based on a generic mid-market risk premium. How do we challenge their cost of capital assumptions to defend our present-value calculation?

Question

Tyler Smith · Accepted Answer

When a buyer's investment banker uses a discounted future earnings model, they often inflate the weighted average cost of capital, or WACC, to discount your future cash flows and drive down your current valuation. You must challenge their cost of capital assumptions by showing that your operational maturity significantly reduces the risk profile of your business.

The WACC calculation includes a company-specific risk premium to account for operational volatility, customer concentration, and key-person dependency. If the banker is using a generic mid-market risk premium of five to eight percent, you must systematically dismantle their risk assumptions.

First, present your historical financial stability. Prove that your cash-to-EBITDA conversion rate is high and predictable.

Second, use your Accountability Chart to prove that the business runs independently of the owner, which eliminates the key-person risk premium.

Third, show that your recurring revenue stream is backed by long-term contract structures, reducing cash flow volatility.

In your deal negotiations, push the buyer to use a capitalization of earnings model or a lower, customized discount rate that reflects your actual risk profile. By proving your business is institutionalized through Step by Step Exit frameworks, you can force the banker to lower their WACC assumptions, which instantly increases the present value of your future cash flows and protects your transaction multiple.
