Equity Carve-Out (IPO of Subsidiary)
The parent company takes a subsidiary public by selling a small slice (say 20%) to outside investors via IPO, keeps the other 80%, pockets the cash, and retains full control. It's like selling a few slices of pie without giving up the whole thing.
Definition
An equity carve-out is a transaction where a parent company sells a minority equity stake (typically 10-20%) in a subsidiary to public investors through an IPO while retaining majority ownership and control (often 80%+). Unlike a spin-off, the parent raises cash from the sale and maintains control of the subsidiary. Carve-outs are used to raise capital, establish a public market valuation for the subsidiary, and potentially set the stage for a full spin-off or sale later.

How a Carve-Out Works
The parent creates a new legal entity for the subsidiary, files an S-1 registration statement, and conducts an IPO selling a minority stake (typically 10-20%) to public investors. The parent retains majority ownership (80%+) and consolidates the subsidiary's financials. The IPO proceeds go to the parent company (primary offering) or to the subsidiary for growth capital. After the carve-out, the subsidiary has publicly traded stock with a market-determined valuation, even though the parent still controls it.
Strategic Advantages
Carve-outs offer several benefits. Cash generation: the parent raises capital without giving up control. Valuation discovery: the public market sets a price for the subsidiary, which may reveal it's worth more than the market gave credit for within the conglomerate. Currency for acquisitions: the subsidiary can use its own publicly traded stock for M&A. Talent retention: the subsidiary can offer stock-based compensation tied to its own performance. Staged separation: a carve-out often precedes a full spin-off, giving the subsidiary time to build standalone operations.
Carve-Out vs. Spin-Off vs. Divestiture
In a carve-out, the parent sells a minority stake via IPO and retains control — it raises cash. In a spin-off, the parent distributes all subsidiary shares to existing shareholders pro-rata — no cash is raised but the businesses are fully separated. In a divestiture, the parent sells the entire subsidiary to a strategic or financial buyer — full separation with maximum cash proceeds. Companies often use a carve-out as the first step, followed by a spin-off of the remaining stake (tax-free under Section 355 if requirements are met).
Worked Example — With Real Numbers
A conglomerate owns a fast-growing cloud division that the market undervalues within the larger company. The parent conducts a carve-out: it IPOs 20% of CloudCo at a $10B implied valuation, raising $2B in cash. The parent retains 80% ownership worth $8B. Before the carve-out, the market implicitly valued the cloud division at only $5B within the conglomerate. The IPO reveals the true value, and the parent's stock rises as the market re-rates the remaining 80% stake.
Key Takeaways
A carve-out IPOs a minority stake in a subsidiary while the parent retains majority control (typically 80%+)
The parent raises cash and the market discovers the subsidiary's standalone valuation
Carve-outs often precede full spin-offs, serving as a staged separation strategy
At 80%+ ownership, the parent still consolidates the subsidiary for financial reporting and tax purposes
Common Mistakes in Interviews
Confusing carve-outs with spin-offs — carve-outs sell new shares to outside investors; spin-offs distribute existing shares to current shareholders
Not recognizing that the parent usually retains 80%+ to maintain tax consolidation benefits
Forgetting that a carve-out creates minority shareholders with rights that may constrain the parent's future actions
How Interviewers Test This
Carve-outs often come up in 'how would you advise a company to separate a division?' questions. Show you know the three options (carve-out, spin-off, divestiture), when each is appropriate, and how they can be combined. A sophisticated point: mention that a carve-out followed by a spin-off of the remaining stake is a common two-step strategy for tax-efficient full separation.
