Sum-of-Parts Valuation: Valuing Diversified Companies
Master sum-of-parts (SOTP) valuation for conglomerates and diversified businesses. Learn segment-by-segment valuation, conglomerate discounts, and spin-off analysis.
Introduction: When Whole ≠ Sum of Parts
“This company has a banking arm, an IT services business, and real estate holdings. How do I value it?”
Sum-of-Parts (SOTP) valuation addresses exactly this challenge. When a company operates in multiple distinct businesses, valuing it as one entity using a single multiple often doesn’t capture its true value. SOTP values each business segment separately and adds them together.
The SOTP Concept
Why SOTP Is Needed
Problem with Traditional Valuation:
A diversified company with IT services and manufacturing can’t be valued at one IT multiple or one manufacturing multiple. Each business deserves its own valuation.
Basic Formula
$$Total\ Value = \sum Value\ of\ Individual\ Segments$$
Or more specifically: $$EV_{Total} = EV_1 + EV_2 + … + EV_n + Net\ Cash - Corporate\ Costs$$
When to Use SOTP
- Conglomerates with diverse businesses
- Companies with valuable subsidiaries
- Spin-off analysis
- Breakup/restructuring scenarios
- Hidden value identification
SOTP Methodology
Step 1: Identify Distinct Segments
Segment Characteristics:
- Different business models
- Different markets
- Different growth profiles
- Different risk characteristics
- Separate management teams (often)
Indian Conglomerate Example:
| Segment | Business | Revenue (₹ Cr) | EBITDA (₹ Cr) |
|---|---|---|---|
| 1 | IT Services | 45,000 | 10,800 |
| 2 | Steel | 28,000 | 3,360 |
| 3 | Power | 12,000 | 3,600 |
| 4 | Retail | 8,000 | 640 |
| 5 | Financial Services | 5,000 | 1,500 |
Step 2: Value Each Segment
Valuation Methods by Segment:
| Segment | Preferred Method | Alternative |
|---|---|---|
| IT Services | EV/EBITDA, P/E | DCF |
| Steel | EV/EBITDA, EV/Ton | DCF |
| Power | DCF, EV/MW | EV/EBITDA |
| Retail | EV/Sales, EV/EBITDA | DCF |
| Financial Services | P/B, P/E | DDM |
Step 3: Select Appropriate Multiples
Use Segment-Specific Comparables:
IT Services:
- Comparable companies: TCS, Infosys, Wipro
- Multiple range: 12-18x EV/EBITDA
Steel:
- Comparable companies: JSW Steel, Tata Steel
- Multiple range: 5-8x EV/EBITDA
Power:
- Comparable companies: NTPC, Tata Power
- Multiple range: 6-10x EV/EBITDA
Step 4: Calculate Segment Values
Example Calculation:
| Segment | EBITDA | Multiple | Segment EV |
|---|---|---|---|
| IT Services | 10,800 | 15x | 162,000 |
| Steel | 3,360 | 6x | 20,160 |
| Power | 3,600 | 8x | 28,800 |
| Retail | 640 | 12x | 7,680 |
| Financial Services | 1,500 | 10x | 15,000 |
| Gross SOTP | 233,640 |
Step 5: Adjust for Corporate Items
Add:
- Cash and equivalents
- Marketable securities
- Real estate (not in segments)
- Listed investments (mark-to-market)
Subtract:
- Debt (at holding company level)
- Corporate overhead (capitalize)
- Minority interests
Example:
| Item | Value (₹ Cr) |
|---|---|
| Gross SOTP | 233,640 |
| + Cash | 8,000 |
| + Listed investments | 12,000 |
| - Corporate debt | (25,000) |
| - Corporate costs (5x) | (3,000) |
| - Minority interests | (15,000) |
| Net SOTP Value | 210,640 |
Conglomerate Discount
What Is Conglomerate Discount?
The market often values diversified companies at less than their SOTP value.
$$Conglomerate\ Discount = \frac{SOTP\ Value - Market\ Cap}{SOTP\ Value} \times 100$$
Reasons for Discount
1. Complexity:
- Harder for investors to understand
- Less analyst coverage per segment
2. Capital Allocation:
- Cross-subsidization concerns
- Suboptimal investment decisions
- Empire building by management
3. Operational Inefficiency:
- Bureaucracy
- Lack of focus
- Higher corporate overhead
4. Governance Issues:
- Complex ownership structures
- Related party transactions
- Minority shareholder concerns
Typical Discounts
| Market | Typical Discount |
|---|---|
| US | 10-15% |
| Europe | 10-20% |
| India | 20-40% |
| Emerging Markets | 15-30% |
Indian conglomerates often trade at higher discounts due to:
- Complex group structures
- Related party concerns
- Promoter holdings
- Historical governance issues
Calculating Implied Discount
Example:
- SOTP Value: ₹210,640 crore
- Current Market Cap: ₹150,000 crore
$$Discount = \frac{210,640 - 150,000}{210,640} = 28.8%$$
Valuing Listed Subsidiaries
Mark-to-Market Approach
When a company owns stakes in listed companies:
$$Stake\ Value = Shares\ Owned \times Current\ Share\ Price$$
Example: Holding Company
Parent Company owns:
| Investment | Stake % | Subsidiary Market Cap | Stake Value |
|---|---|---|---|
| Listed Sub A | 75% | ₹40,000 Cr | ₹30,000 Cr |
| Listed Sub B | 55% | ₹25,000 Cr | ₹13,750 Cr |
| Listed Sub C | 40% | ₹10,000 Cr | ₹4,000 Cr |
| Total Investment Value | ₹47,750 Cr |
Holding Company Discount
Additional discount applied because:
- Tax leakage on dividends
- Inability to realize full value immediately
- Governance/complexity
- Liquidity of holding company shares
Typical holding company discount: 20-50%
Special Considerations
Intercompany Transactions
Eliminate double-counting:
- Transfer pricing
- Management fees
- Brand royalties
- Intercompany loans
Shared Services
Allocate corporate costs:
- Finance function
- HR
- IT infrastructure
- Legal and compliance
Methods:
- Revenue-based allocation
- Asset-based allocation
- Headcount-based allocation
Synergies Between Segments
May exist value from:
- Cross-selling
- Shared infrastructure
- Brand leverage
- Tax optimization
Consider: If segments were separate, some synergies would be lost.
Minority Interests
Treatment:
- Value 100% of segment
- Subtract minority share as adjustment
- Or value only proportional ownership
SOTP for Different Company Types
Industrial Conglomerates
Indian Examples: Tata Group companies, Reliance Industries, Adani Group
Approach:

- Add investments in listed companies
- Significant corporate adjustments
Financial Holding Companies
Indian Examples: HDFC Ltd (pre-merger), Bajaj Holdings
Approach:
- Value banking subsidiary

Interpretation
Is the discount justified?
Arguments for higher discount:
- Complex structure
- Corporate governance concerns
- Capital allocation track record
Arguments for lower discount:
- Strong individual businesses
- Improving governance
- Potential for value unlocking
Value Unlocking Strategies
Spin-offs
Separate business units into standalone companies:
- Each gets dedicated management
- Focused investor base
- Appropriate valuation multiple
Indian Example: Jio-Reliance Retail separation from core business
IPO of Subsidiaries
List subsidiary separately:
- Establishes market value
- Provides liquidity
- Reduces holding discount
Asset Sales
Sell non-core businesses:
- Focus remaining business
- Reduce complexity
- Return cash to shareholders
Restructuring
Simplify corporate structure:
- Merge overlapping entities
- Eliminate circular holdings
- Improve governance
Key Takeaways
- SOTP values parts separately – Then aggregates
- Use segment-specific multiples – Not one-size-fits-all
- Conglomerate discount exists – 20-40% in India common
- Mark listed investments to market – Add as investment value
- Adjust for corporate items – Debt, cash, overhead, minorities
- Compare to trading price – Identify discount/premium
- Consider value unlocking – Spin-offs, sales, restructuring

Frequently Asked Questions
Q: Why do conglomerates trade at a discount? A: Complexity, capital allocation concerns, governance issues, and lack of focus make investors discount these companies. They prefer “pure play” investments.
Q: How do I value private subsidiaries? A: Use comparable company analysis or DCF based on available segment information. Less precision is expected for non-listed entities.
Q: Should I apply holding company discount separately? A: Yes, for pure holding companies. For operating conglomerates with some listed stakes, a combined conglomerate discount is more common.
Q: What if segment information isn’t disclosed? A: Use segment revenue if EBITDA isn’t available, estimate margins based on comparables, or value at consolidated level with adjustments.
Q: Can SOTP be higher than market value? A: Yes, this indicates a conglomerate discount. It may signal undervaluation or reflect legitimate concerns about the company structure.
SOTP is like valuing a property portfolio—you value each property individually based on its type, location, and condition, then add them up. The total might be more than what someone would pay for the entire portfolio at once, because managing many properties is more complex than owning one.
