Sum-of-the-Parts Valuation: How Smart Indian Value Investors Unlock Hidden Value in Conglomerates Like ITC, Reliance, and Grasim — The Underused Valuation Method That Reveals True Worth When P/E Ratios Lie and Market Caps Mislead

The ₹80,000 Crore Hidden in Plain Sight

In January 2025, something extraordinary happened on the Indian stock market. Without issuing a single new share, without raising a single rupee of capital, and without selling a single asset — ITC Limited unlocked close to ₹80,000 crore of shareholder value overnight. How? By simply separating its hotels business into a new listed entity called ITC Hotels Limited.

For decades, analysts like Motilal Oswal and Jefferies had been screaming the same number: ITC’s hotels division was worth ₹80-100 per share, but the market was valuing it at almost zero because it was buried inside a “cigarettes and FMCG” company that traded at cigarette multiples. The moment the hotels business got its own ticker, the market applied hospitality-sector multiples (20-30x EV/EBITDA) and the value was no longer “hidden.”

This wasn’t magic. It wasn’t insider information. It was the result of a single, powerful valuation technique that every serious Indian value investor must master — and that most retail investors have never even heard of. It’s called Sum-of-the-Parts (SOTP) valuation, and today, I’m going to teach you how to use it to find the next ₹80,000 crore hidden in plain sight.

Today’s Market Context: Why SOTP Matters Right Now

In a market like this, with indices near all-time highs and many large-caps looking expensive on standard P/E metrics, SOTP valuation becomes one of the most powerful tools in your arsenal. It lets you see what the market is missing.

What Is Sum-of-the-Parts Valuation?

Sum-of-the-parts (SOTP) valuation is a method of valuing a company by separating it into its individual business segments, valuing each segment independently using the multiple most appropriate to that segment, and then adding them together to arrive at a total enterprise value.

The core insight is simple but profound: a single P/E ratio, applied to a diversified company, is almost always wrong. A company that earns 50% of its profits from a stable FMCG business, 30% from a cyclical commodity business, and 20% from a high-growth digital business cannot be fairly valued using one blended multiple. Each of those businesses has a fundamentally different risk profile, growth trajectory, and capital intensity — and therefore deserves its own valuation multiple.

When the market lazily applies a blended P/E to such a company, it almost always underweights the highest-quality segment and overweights the worst. This creates a persistent mispricing — and for the patient value investor who does the SOTP work, it creates an opportunity.

The 5-Step SOTP Process Every Indian Investor Must Know

Step 1: Identify the distinct business segments. Read the annual report’s segmental reporting section (it’s legally required under Ind AS 108). Most diversified Indian companies break out revenue, EBITDA, and capital employed by segment. For ITC, this means Cigarettes, FMCG (excluding cigarettes), Hotels, Paperboards & Packaging, and Agribusiness. For Bajaj Finserv, it means Bajaj Finance (NBFC), Bajaj Allianz General Insurance, Bajaj Allianz Life Insurance, and the asset management arm.

Step 2: Assign the right valuation multiple to each segment. This is where expertise matters. Cigarettes deserve a low-teens multiple because of regulatory risk and slow volume growth. FMCG brands with scale and pricing power deserve 50-60x P/E. Hospitality deserves 20-30x EV/EBITDA. NBFCs should be valued on Price-to-Book Value (typically 2-5x for quality lenders). Life insurance uses Embedded Value multiples. Getting the multiple right for each segment requires understanding the peer set for that industry — this is where reading dozens of sector reports pays off.

Step 3: Apply the multiple to the segment’s earnings or book value. If the FMCG division earned ₹2,000 crore in EBITDA and you believe a 30x multiple is fair (based on HUL, Nestle, and Britannia comparables), that segment is worth ₹60,000 crore. Repeat for every segment.

Step 4: Add any non-operating assets. Cash on the balance sheet, investments in other listed companies (valued at their current market price, not book value), real estate, and treasury holdings all get added on top of the operating business value.

Step 5: Subtract net debt and apply the holding company discount. Subtract total debt, minority interests, and any pension liabilities. Then, if the company is structured as a pure holding company, apply a “holdco discount” — typically 20-40% in India — because the market historically penalises holding structures for tax inefficiency, opacity, and lack of direct operating exposure.

The Indian SOTP Hall of Fame: Three Case Studies

Case Study 1 — ITC Limited. Pre-demerger, Motilal Oswal’s SOTP math valued the stock at ₹520-570: cigarettes at 25x, FMCG at 60x (on growing brands like Sunfeast, Bingo, Savlon, Yippee), agribusiness at 15x, paperboards at 12x, and hotels at 30-35x EV/EBITDA. The hotels business alone was calculated to be worth ₹80-100 per ITC share — completely invisible in the traded price. On January 6, 2025, ITC Hotels got its own ticker and the ₹80,000 crore+ valuation that had been buried was finally made explicit. ITC shareholders received one ITC Hotels share for every 10 ITC shares, and the market immediately assigned hospitality multiples. That’s SOTP in action.

Case Study 2 — Bajaj Finserv. For years, Bajaj Finserv traded at what looked like a modest P/E on a consolidated basis. But SOTP analysis revealed a completely different picture: Bajaj Finance (then held at ~52%) alone, valued at its market cap, contributed most of Bajaj Finserv’s market value. Bajaj Allianz Life and Bajaj Allianz General — valued on embedded value and 2x book respectively — added another massive layer. The insurance businesses were essentially being given away for free to patient SOTP investors who understood the structure.

Case Study 3 — Grasim Industries. Grasim holds major stakes in UltraTech Cement, Aditya Birla Capital, and Vodafone Idea (legacy), plus its own Viscose Staple Fibre, Chemicals, and Paints businesses. A naive P/E on Grasim’s consolidated numbers tells you nothing. A proper SOTP — valuing UltraTech at its market price, ABCL at Price-to-Book, the core VSF business at 15x earnings, and deducting the Vodafone Idea drag — has consistently revealed Grasim to be trading at a 25-40% holding company discount. For the value investor willing to accept that discount, the math has historically compounded beautifully.

The Holding Company Discount: India’s Most Persistent Mispricing

Indian markets apply a brutal discount to pure holding companies — Tata Investment Corporation, Bajaj Holdings, Maharashtra Scooters, Bombay Burmah, Kalyani Investment, and others often trade at 40-60% discounts to their mark-to-market NAV. Why? Three reasons: (1) investors can’t directly access the underlying businesses and fear they never will, (2) dividend leakage through multiple layers creates tax inefficiency, (3) historical distrust of Indian holding structures from pre-liberalisation era family-owned conglomerates.

For the patient value investor, this discount can be an opportunity if and only if there’s a credible catalyst that will narrow it — a buyback, a merger, a demerger, a dividend policy change, or a management that has publicly committed to unlocking value. Without a catalyst, the discount can persist for a decade. Bajaj Holdings traded at a 50% discount for years before finally compounding meaningfully.

Three Common SOTP Mistakes That Destroy Returns

Mistake 1 — Using peak multiples across all segments. If cement is at a cyclical peak with 25x P/E and chemicals is at peak with 40x P/E, do not use those peak multiples in your SOTP. Use mid-cycle multiples. SOTP is only as good as the multiples you feed it.

Mistake 2 — Ignoring corporate overheads and unallocated costs. Diversified companies carry group-level corporate costs — legal, treasury, head office, the Chairman’s secretariat — that are not allocated to any single segment. These costs are real and must be capitalised (typically at 10-12x) and subtracted from the SOTP total.

Mistake 3 — Forgetting catalysts. An SOTP that screams “undervalued by 40%” is worthless if there’s no catalyst to close the gap. Ask yourself: what will force the market to recognise this value? A demerger? A restructuring? Activist pressure? Without a catalyst, “fair value” can remain a forever-dream.

SOTP and the Philosophy of Concentrated Conviction Investing

Here’s the deeper lesson. SOTP valuation demands that you truly understand every piece of a business before you invest. You can’t mechanically run an SOTP on 50 stocks in a weekend — it takes dozens of hours of reading annual reports, sector studies, and management commentary for each name. This naturally forces you into concentrated investing — the same philosophy that Warren Buffett, Charlie Munger, Mohnish Pabrai, and Rakesh Jhunjhunwala built their fortunes on.

As Buffett famously said: “Wide diversification is only required when investors do not understand what they are doing.” When you do the SOTP work — segment by segment, multiple by multiple, catalyst by catalyst — you end up with a handful of deeply understood names that you are willing to size meaningfully. That’s how real wealth gets built. Not by spreading your capital across 50 mediocre ideas “for safety,” but by concentrating it in the 5-10 businesses you understand better than 99% of the market.

The F&O Contrast: Why SOTP Investors Laugh at Option Gamblers

Key Takeaways

Sum-of-the-parts valuation is not just another valuation technique — it is a fundamentally different way of thinking about businesses. It forces you to separate signal from noise, to see the mispriced gem inside the conglomerate, and to understand what you own piece by piece. ITC’s hotels demerger was not a stroke of genius — it was the market finally catching up to what SOTP investors had known for years. Your job, as a serious value investor, is to find the next ITC Hotels before the market catches up. And then to concentrate your capital with conviction when you do.
