Three Discounted Cash Flow Models That Show ESG’s Impact on Valuation

While ESG is often discussed in theoretical or policy terms, its impact on valuation can be modeled with surprising clarity. Using the discounted cash flow (DCF) method, analysts can simulate how different ESG outcomes—positive, neutral, or negative—affect the value of a privately-held business.

To demonstrate this, we applied DCF modeling to a hypothetical company using industry benchmark data. The business profile: a full-service restaurant with annual revenues between $5 million and $25 million. By adjusting cash flows and risk profiles, we quantified the valuation impact of three ESG scenarios.

Scenario 1: No ESG Impact (Baseline)

In this model, the business neither benefits nor suffers from ESG practices. Financial performance and risk factors remain unchanged. Using standard industry data, a weighted average cost of capital (WACC) of 15.07%, and a 3.5% perpetual growth rate, the baseline value of the company was calculated at $2.88 million (controlling, nonmarketable equity interest).

This scenario serves as the control for comparing ESG-driven deviations.

Scenario 2: Positive ESG Impact

Here, ESG practices were successfully implemented. The assumptions included:

• Revenue growth exceeding the long-term sustainable rate (up 10.5%)

• Expense increases across multiple categories (e.g., 10% higher salaries, 15% increase in cost of goods sold)

• Lower risk profile, resulting in a reduced WACC of 14.53%

Despite the expense hikes, the increase in cash flow and the drop in perceived risk led to a fair market value of equity at $3.12 million—an 8.59% increase over the baseline.

This scenario reflects the ideal ESG outcome: enhanced reputation, revenue growth, risk mitigation, and investor preference all translating into higher value.

Scenario 3: Negative ESG Impact

In this model, ESG adoption failed to deliver expected returns. Key assumptions included:

• Revenue growth held to the long-term average of 3.5%

• The same ESG-driven expense increases as Scenario 2

• An increase in risk, pushing the WACC up to 15.61%

The result? A sharp drop in equity value to $1.27 million—a 55.93% decrease from the baseline.

This scenario illustrates the potential downside of poorly planned ESG integration. If costs rise without a corresponding gain in revenue or risk reduction, value suffers significantly.

Key Takeaways for Business Owners and Valuation Analysts

1. ESG outcomes are not binary. They exist on a spectrum—and so does their valuation impact.

2. Expense increases are expected. The question is whether they’re offset by increased revenue or reduced risk.

3. Risk modeling is critical. Even small adjustments to the company-specific risk premium or WACC can produce large changes in value.

4. Implementation quality matters. The most important factor isn’t whether ESG is adopted, but how effectively it’s integrated into operations.

These findings highlight a core truth: ESG is no longer just a reputational concern—it’s a valuation lever. Business owners seeking funding, preparing for an exit, or managing investor relationships should understand how ESG influences both financial performance and risk—and how that, in turn, affects value.
