Sum-of-Parts, Asset-Based Valuation & Other Methods

Sum-of-Parts (SOTP) Valuation — When a Company is Worth More Than Its Parts

Sometimes, a company operates in multiple businesses, and the market values it based on its overall earnings. But if you break the company into its individual business segments, the total value of each segment separately might be HIGHER than the company's current market value. This is called the "conglomerate discount" — the market undervalues diversified companies because they're harder to analyze.

Sum-of-Parts valuation values each business segment separately and adds them up to get the total company value.

When to Use SOTP:

• The company operates in multiple unrelated businesses (like Tata Group companies, Reliance Industries, ITC)
• One segment might be dragging down the valuation of other segments
• The company has significant investments in other companies (holdings, subsidiaries)
• The market is not recognizing the full value of certain business segments

How SOTP Works:

1. Identify all business segments and investments
2. Choose the appropriate valuation metric for each segment (P/E for profitable businesses, EV/EBITDA for capital-intensive businesses, P/B for financial businesses)
3. Apply industry-appropriate multiples to each segment
4. Sum up all segment values
5. Subtract net debt
6. Divide by number of shares to get per-share value

Example — SOTP Valuation of ITC Limited:

ITC operates in five distinct businesses:

1. FMCG (Non-Tobacco): Brands like Aashirvaad, Sunfeast, Bingo, etc.

   • Revenue: ₹18,000 crore
   • EBITDA: ₹2,500 crore
   • Appropriate Multiple: 35x EV/EBITDA (FMCG peers)
   • Segment Value: ₹87,500 crore

2. Cigarettes/Tobacco: India's largest cigarette manufacturer

   • Revenue: ₹28,000 crore
   • EBIT: ₹15,000 crore
   • Appropriate Multiple: 12x P/E (tobacco companies trade at lower multiples)
   • Segment Value: ₹1,80,000 crore

3. Hotels: ITC Hotels chain

   • Revenue: ₹3,500 crore
   • EBITDA: ₹800 crore
   • Appropriate Multiple: 20x EV/EBITDA
   • Segment Value: ₹16,000 crore

4. Agri-Business: Farm-to-plate supply chain

   • Revenue: ₹5,000 crore
   • EBITDA: ₹500 crore
   • Appropriate Multiple: 15x EV/EBITDA
   • Segment Value: ₹7,500 crore

5. Paper & Packaging:

   • Revenue: ₹3,000 crore
   • EBITDA: ₹400 crore
   • Appropriate Multiple: 12x EV/EBITDA
   • Segment Value: ₹4,800 crore

6. Investments and Other Assets: ₹10,000 crore

Total Enterprise Value: ₹87,500 + ₹1,80,000 + ₹16,000 + ₹7,500 + ₹4,800 + ₹10,000 = ₹3,05,800 crore

Less Net Debt: ₹2,000 crore

Equity Value: ₹3,03,800 crore

Per Share (with 124 crore shares): ₹2,450

If the current market price is ₹450, the SOTP analysis suggests ITC might be significantly undervalued — but this analysis also shows that the FMCG business (which gets the highest multiple) is a significant contributor to value.

SOTP Limitations:

1. Choosing the right multiple for each segment is subjective
2. Some segments may not have clear comparable companies
3. Conglomerate discounts can persist for years
4. The analysis can be complex for companies with many business segments

Asset-Based Valuation — What is the Company's Assets Worth?

Asset-based valuation values a company based on the net value of its assets. This is most useful for:

• Asset-heavy companies: Manufacturing, real estate, infrastructure
• Companies being liquidated: When a company is shutting down, its assets are sold
• Banks and financial institutions: Book value is a meaningful measure
• Investment companies: The value of their investment portfolio

Two Main Approaches:

1. Book Value Method:

Book Value = Total Assets - Total Liabilities

This is the simplest form of asset-based valuation. It uses the values reported in the company's balance sheet.

Example: If a company has total assets of ₹10,000 crore and total liabilities of ₹4,000 crore, the book value is ₹6,000 crore. If there are 10 crore shares, the book value per share is ₹600.

When Book Value Works:

• Banks (book value reflects the loan portfolio)
• Insurance companies
• Real estate companies (if assets are marked to market)
• Companies with minimal intangible assets

When Book Value Doesn't Work:

• IT services companies (value is in people, not assets)
• FMCG companies (brand value not in book value)
• Technology companies (intellectual property not reflected)
• Companies with outdated asset values

2. Net Asset Value (NAV) Method:

NAV adjusts the book value to reflect the current market value of assets. This is particularly useful for:

• Real estate companies: Properties may have appreciated significantly since they were purchased, but the balance sheet still shows historical cost.
• Investment companies: The market value of their investments may be very different from the book value.

Example: A real estate company owns land purchased for ₹500 crore (book value). The current market value of the land is ₹2,000 crore. The NAV method would use ₹2,000 crore instead of ₹500 crore, adding ₹1,500 crore to the company's value.

How to Calculate NAV:

1. Start with book value of equity
2. Add: Appreciation in real estate (market value - book value)
3. Add: Appreciation in investments (market value - book value)
4. Subtract: Any contingent liabilities or provisions
5. Result: Adjusted NAV

Other Valuation Methods — Quick Overview

1. Dividend Discount Model (DDM):

Values a stock based on the present value of all future dividends. Best for:

• High-dividend-paying stocks (Coal India, Power Grid, ITC)
• Utility companies with stable dividends
• Companies with long dividend histories

Formula: Value = D₁ / (r - g) Where D₁ = next year's expected dividend, r = required return, g = dividend growth rate

When to Use DDM:

• Company has a long, stable dividend history
• Dividends are expected to grow at a steady rate
• The company is mature and generates consistent cash flows

When NOT to Use DDM:

• Companies that don't pay dividends
• Companies with volatile dividends
• Growth companies that reinvest all profits

Example — DDM Valuation of Power Grid Corporation:

Current Dividend: ₹5.50 per share Expected Growth: 8% per year Required Return: 12%

Value = ₹5.50 × 1.08 / (0.12 - 0.08) = ₹5.94 / 0.04 = ₹148.50

If the current price is ₹260, the DDM suggests Power Grid is overvalued at the current price. However, the DDM assumes a constant growth rate forever, which may not be realistic.

2. EV/Revenue Valuation:

Useful for companies that are not yet profitable or have very thin margins.

EV/Revenue = Enterprise Value ÷ Revenue

When to Use:

• Early-stage companies
• Companies with negative earnings
• Comparing companies with different cost structures

Typical EV/Revenue Ranges:

• IT Services: 5-10x
• FMCG: 8-15x
• Manufacturing: 2-5x
• Startups: 1-20x (highly variable)

3. Replacement Cost Method:

Estimates the cost of recreating the company's assets from scratch. This is useful for:

• Infrastructure companies (power plants, roads, ports)
• Manufacturing companies with significant capital investment
• Companies with unique assets that are difficult to replicate

How It Works:

1. Identify all major assets (factories, equipment, land, intellectual property)
2. Estimate the cost of building or acquiring each asset today
3. Subtract liabilities
4. The result is the replacement cost value

Example: A cement company owns a plant built 10 years ago for ₹1,000 crore. The book value (after depreciation) is ₹400 crore. But building the same plant today would cost ₹2,500 crore. The replacement cost method would value the plant at ₹2,500 crore.

Choosing the Right Valuation Method — A Decision Framework

Scenario	Best Method	Why
Stable, dividend-paying company	DDM or P/E	Dividends are predictable and meaningful
High-growth company	P/E (forward) or PEG	Future earnings growth is the key driver
Multi-business conglomerate	SOTP	Each business should be valued separately
Asset-heavy company	P/B or NAV	Assets are the primary source of value
Unprofitable startup	EV/Revenue or P/S	Earnings don't exist yet
Cyclical company	EV/EBITDA or P/B	Earnings vary with the cycle
Bank or financial company	P/B	Book value reflects the asset base
Mature, stable company	DCF	Cash flows are predictable
Quick screening	P/E, P/B	Easy to calculate and compare

Building a Comprehensive Valuation — Putting It All Together

The best valuation approach uses multiple methods and takes a weighted average:

Step 1: DCF Valuation Calculate the DCF value using reasonable assumptions.

Step 2: Relative Valuation Compare P/E, EV/EBITDA, and P/B to peers and historical averages.

Step 3: SOTP (if applicable) If the company has multiple business segments, do an SOTP analysis.

Step 4: DDM (if applicable) If the company pays consistent dividends, do a DDM analysis.

Step 5: Weighted Average Assign weights based on your confidence in each method:

• DCF: 30-40% (most theoretically sound but assumption-heavy)
• Relative: 30-40% (practical and widely used)
• SOTP: 10-20% (if applicable)
• DDM: 5-10% (if applicable)

Step 6: Margin of Safety Apply a 15-25% margin of safety to account for errors in your assumptions. If the weighted average valuation is ₹500, only buy if the market price is below ₹425 (15% margin of safety).

Summary — Key Takeaways

1. SOTP valuation is powerful for diversified companies — it can reveal hidden value that the market overlooks.

2. Asset-based valuation works best for asset-heavy companies (banks, real estate, manufacturing) and is less useful for service or technology companies.

3. DDM is ideal for stable, dividend-paying companies like Power Grid and Coal India.

4. No single valuation method is perfect — use multiple methods and take a weighted average.

5. Always apply a margin of safety (15-25%) to account for errors in your assumptions.

6. The best valuation approach depends on the specific company — match the method to the company's characteristics.
