SOTP Valuation for TMT Conglomerates

Introduction

Sum-of-the-parts valuation is the appropriate framework whenever a TMT company operates business segments with materially different growth profiles, margin structures, and appropriate valuation multiples. This describes virtually every large-cap TMT company: Alphabet combines advertising, cloud computing, and autonomous vehicles; Amazon combines e-commerce, cloud infrastructure, advertising, and logistics; Disney combines streaming, linear TV, theme parks, and film studios; Microsoft combines productivity software, cloud infrastructure, gaming, and LinkedIn. Applying a single EV/EBITDA or P/E multiple to these companies obscures the value contribution of high-growth segments and overstates the value of mature or declining segments. SOTP analysis disaggregates the company into its component businesses, applies segment-appropriate multiples to each, and sums the implied values to derive a total enterprise value that more accurately reflects the company's composition.

The mechanics of SOTP are straightforward: identify the distinct business segments, project revenue and profitability for each, assign an appropriate multiple to each segment based on comparable pure-play companies, and sum the results. The analytical challenge lies in three areas: segment definition, multiple selection, and handling of shared costs and intercompany revenue.

The SOTP Process for TMT Companies

Step 1: Segment identification. Use the company's financial reporting segments as a starting point, but refine based on economic reality. Amazon reports three segments (North America, International, AWS), but an SOTP analysis should further disaggregate North America into e-commerce, advertising, and subscription (Prime). Step 2: Segment financials. Project revenue, operating income, and EBITDA for each segment. Use segment-level disclosures from 10-K filings and earnings supplements. For segments that share costs (corporate overhead, shared technology platforms), allocate costs proportionally based on revenue or headcount. Step 3: Comparable selection. Identify pure-play companies or precedent transactions for each segment. AWS compares to Microsoft Azure (via Microsoft's Intelligent Cloud segment) and Google Cloud; Amazon Advertising compares to Meta's Family of Apps and Alphabet's advertising revenue. Step 4: Multiple application. Apply the selected multiple to each segment's metric (EV/Revenue for high-growth segments, EV/EBITDA for mature segments). Step 5: Summation and adjustments. Sum the segment values, add the value of non-operating assets (cash, investments, venture stakes), and subtract net debt to arrive at implied equity value.

TMT conglomerates typically trade at a 13-15% discount to the sum of their segment values, a phenomenon documented across decades of academic research and observed consistently in TMT.

Microsoft presents another instructive SOTP case. Microsoft Cloud surpassed $40 billion in quarterly revenue in Q2 2025, growing 21% year-over-year. The Intelligent Cloud segment alone ($32.9 billion quarterly revenue) would be among the most valuable standalone technology companies in the world if separated. Yet Microsoft's cloud value is partially obscured by its bundling with Office 365, Windows, LinkedIn, and Xbox gaming. A proper SOTP would value Azure/Intelligent Cloud on revenue multiples comparable to AWS (using Amazon's segment disclosures), Office 365 and productivity on EV/EBITDA comparable to mature software businesses, LinkedIn on digital advertising and subscription multiples, and gaming (including the $75.4 billion Activision acquisition) on gaming industry precedent multiples.

Meta's Family of Apps generated $58.9 billion in Q4 2025 revenue, while Reality Labs (metaverse hardware and software) continues to lose billions annually. An SOTP analysis reveals that Family of Apps alone could justify Meta's entire market capitalization, implying that the market assigns near-zero or negative value to Reality Labs, which represents a bet on whether Meta's metaverse investment will eventually generate returns. Meta's AI-powered advertising reached a $20 billion annual run rate by March 2025, creating a new valuation dimension: how to assign incremental value to AI capabilities embedded within the core advertising business.

Disney's SOTP is particularly complex because its segments span streaming (Disney+, Hulu, ESPN+, valued on EV/Subscriber), linear TV and cable networks (valued on declining EV/EBITDA), theme parks (valued on EV/EBITDA with scarcity premium), and film studios (valued on content library approaches). The interaction between segments (theatrical releases driving theme park attendance and merchandise sales) creates genuine synergies that a pure SOTP analysis may undervalue.
