How should analysts quantify the valuation discount for dual-class share structures?

Question

AcadiFi · Accepted Answer

Quantifying the dual-class discount is more art than science, but there are several frameworks the CFA curriculum and practitioners use.

**Why a Discount Exists:**
Dual-class structures create agency costs because controlling shareholders can make decisions that benefit themselves at the expense of minority shareholders. This includes:
- Excessive executive compensation
- Related-party transactions
- Resistance to value-maximizing takeovers
- Pet projects and empire building

**Methods to Estimate the Discount:**

**Method 1: Voting Premium Approach**
When both share classes trade publicly, the price difference directly reveals the voting premium:

Voting Premium = (Price_high-vote - Price_low-vote) / Price_low-vote

Historical data shows voting premiums of 5-50%, depending on the country and probability of a control event.

**Method 2: Comparable Company Discount**
Compare the P/E or EV/EBITDA of dual-class companies to single-class peers:

Dual-Class Discount = 1 - (Multiple_dual / Multiple_single)

Academic studies find dual-class firms trade at an average 10-15% discount to matched single-class firms.

**Method 3: Governance Score Adjustment**
Use governance ratings (e.g., ISS, MSCI ESG) as a proxy. Firms with weaker governance receive higher discount rates in DCF models:

Adjusted COE = Base COE + Governance Risk Premium (50-200 bps)

**Worked Example:**
PhoenixTech has Class A shares (1 vote) trading at $85 and Class B shares (10 votes) held by founder Dmitri Volkov — not publicly traded. Comparable single-class tech firms trade at 22x forward earnings. PhoenixTech trades at 18.5x.

Discount = 1 - (18.5 / 22.0) = 1 - 0.841 = **15.9%**

Alternatively, in a DCF:
- Base cost of equity: 10.0%
- Governance premium for dual-class: +1.5%
- Adjusted cost of equity: 11.5%

With a $4.00 forward EPS growing at 6%:
- Value at 10.0%: $4.00 / (0.10 - 0.06) = $100
- Value at 11.5%: $4.00 / (0.115 - 0.06) = $72.73
- Implied discount: 27.3%

**Factors Affecting Discount Magnitude:**

| Factor | Lower Discount | Higher Discount |
|--------|---------------|----------------|
| Sunset provision | Yes (converts to single-class) | No sunset |
| Independent board majority | Strong independence | Founder-controlled board |
| Founder track record | Exceptional operator | Mixed/poor decisions |
| Country governance standards | Strong legal protections | Weak minority rights |
| Probability of control change | Higher | Lower |

**Exam Application:** The CFA exam might give you two comparable companies — one single-class and one dual-class — and ask you to estimate the appropriate discount or adjust the cost of equity. Be prepared to qualitatively assess governance factors that amplify or mitigate the discount.
