    Sum of the Parts Valuation (SOTP)

    SOTP values each business segment separately instead of applying one multiple to the whole company. It reveals whether the market is undervaluing a conglomerate's pieces.

    Definition

    Sum of the Parts (SOTP) valuation values each distinct business segment of a company independently — using the valuation methodology most appropriate for that segment — then adds them together to derive a total enterprise value. It is commonly used for conglomerates, diversified companies, and spin-off analysis.

    SOTP vs Straight Comps

    Why a single multiple can mislead for diversified companies

    Straight CompsSingle blended multiple applied to total EBITDA
    $3.8B

    $508M EBITDA x 7.5x = $3.8B

    $3.8B
    SOTP ApproachEach segment valued at its own appropriate multiple
    $4.3B

    A: 8x + B: 12x + C: 6x = $4.3B

    $4.3B

    SOTP reveals $500M of hidden value (13% more) because the high-growth tech segment deserves a higher multiple than the blended average.

    Why the Discount Exists

    Complexity penalty

    Analysts struggle to value diverse businesses — so they apply a lower multiple

    Capital misallocation

    Internal capital markets are less efficient than external ones

    Management distraction

    Running 3 different businesses means focus is diluted across segments

    Activist catalyst

    The discount creates an opportunity for activists to push for a breakup

    When to Use SOTP

    SOTP is appropriate when a company has multiple segments operating in different industries with different growth profiles, margins, and risk. Examples include conglomerates (GE, Berkshire), diversified industrials, media companies with streaming and legacy segments, and tech companies with cloud and hardware divisions. Using a single blended multiple would undervalue high-growth segments and overvalue low-growth ones.

    How to Build a SOTP Analysis

    For each segment: (1) identify the appropriate metric (EBITDA, revenue, subscribers), (2) select comparable pure-play companies, (3) apply the relevant multiple. Sum all segment values to get total enterprise value. Subtract net debt and other claims to get equity value. In a pitch book, SOTP is often presented alongside DCF and comps as a valuation cross-check.

    Conglomerate Discount

    Conglomerates often trade at a 10–20% discount to the sum of their parts — the 'conglomerate discount.' This discount arises from complexity, capital misallocation across segments, and lack of management focus. Activist investors often argue for spin-offs or divestitures to 'unlock' this value by allowing each business to trade at its standalone multiple.

    Worked Example — With Real Numbers

    A company has three segments: (1) Software — $200M EBITDA at 15x = $3B, (2) Manufacturing — $300M EBITDA at 8x = $2.4B, (3) Retail — $100M EBITDA at 6x = $600M. Total EV = $6B. A blended multiple on $600M total EBITDA = 10x would also give $6B, but SOTP reveals where the value sits and shows the software segment is the crown jewel.

    Key Takeaways

    1

    SOTP values each segment using its own appropriate methodology and peer set

    2

    It is essential for diversified companies where a single multiple would be misleading

    3

    Conglomerates often trade at a 10–20% discount to the sum of their parts

    4

    SOTP is a powerful tool for activist investors arguing for spin-offs or divestitures

    Common Mistakes in Interviews

    Using the same multiple for all segments instead of finding appropriate pure-play comps for each

    Forgetting to allocate corporate overhead costs across segments or deducting them centrally

    Double-counting or omitting intercompany transactions between segments

    How Interviewers Test This

    If asked 'how would you value a conglomerate?', say SOTP. Walk through the steps: segment the business, find pure-play comps for each, apply appropriate multiples, sum and subtract net debt. Mention the conglomerate discount as a follow-up.
