How do you treat hybrid capital—such as subordinated debt, preference shares, or convertibles—when calculating Enterprise Value?
As it turns out, overlooking just one adjustment can completely flip how a deal looks on paper. Today, let’s discuss a common pitfall in WACC (Weighted Average Cost of Capital) that is often ignored in practice.
1. Hybrids are Not 100% Debt
As the name suggests, hybrid capital blends the features of both Debt and Equity.
In many valuation models, analysts treat these instruments as "100% Debt" to simplify the math (Naive WACC). This is where the trouble begins.
The Debt Face: Fixed interest payments and repayment obligations.
The Equity Face: Subordinated ranking, ability to defer dividends, and potential conversion into shares.
Just as accounting standards like IAS 32 require splitting these into debt and equity components, your valuation should also "unbundle" these layers to reflect their true economic cost.
2. The Numerical Impact of Refinement
What happens when you correctly split the hybrid components and recalculate WACC? Let’s look at a simulation for an Emerging Markets (EM) deal:
Valuation Approach | WACC Result | Impact on Enterprise Value (EV) |
Naive Calculation | 7.0% | Base Value |
Refined Calculation | 8.8% | ~26% Decrease |
A mere 1.8% jump in WACC can slash the Enterprise Value by more than a quarter.
Why is the gap so large?
The "equity-like" portion of hybrid capital carries significantly higher risks—such as illiquidity and payment deferral. To be precise, this portion should be priced at a much higher cost (e.g., 18–20%) compared to simple after-tax debt.
3. Why This Matters Now
This adjustment is a "deal-swinger," especially in capital-heavy industries requiring massive infrastructure investment, or in ASEAN markets where hybrid financing is prevalent.
Even if the projected cash flows remain the same, your "WACC lens" determines whether a deal is a "Go" or a "No-go."
Summary: Don't Be Misled by Surface Numbers
The assumption that "treating hybrids as debt is the conservative/safe route" can lead to massive investment errors.
Break down the unique characteristics of the hybrid instrument.
Reflect the true cost of the "equity leg" based on its actual risk profile.
This small step leads to more accurate, and ultimately more persuasive, investment decisions. For your next deal, why not take a peek "under the hood" of your WACC?
