What Is a Spin-Off? The 2026 Guide to Corporate Spin-Offs

“A spin-off doesn’t sell a business , it sets it free. The parent separates a unit into its own independent company and hands it to existing shareholders, betting that two focused companies are worth more than one combined.”

Key Takeaways

• A spin-off separates a business unit from its parent into a new, independent company.
• In a classic spin-off, shares of the new company are distributed to the parent’s existing shareholders.
• A spin-off is a distribution, not a sale , it doesn’t bring cash to the parent from a buyer.
• Companies pursue spin-offs to unlock value, sharpen focus, and let distinct businesses stand alone.
• A spin-off differs from a carve-out, which is a sale of a unit to a buyer for cash.
• Both spin-offs and carve-outs are types of divestiture , ways a company separates a business unit.
• After a spin-off, the parent and the new company operate as two separate, independent businesses.

Spin-Off Defined

A spin-off is a corporate action in which a parent company separates one of its business units, divisions, or subsidiaries into a brand-new, independent company. The unit that was part of the parent becomes its own standalone company.

The defining feature of a classic spin-off is how the ownership of the new company is handled: the parent company distributes the shares of the new, separated company to its own existing shareholders. The shareholders don’t pay for those shares , they receive them. After the spin-off, the parent’s shareholders own shares in two separate companies: the parent (now without the spun-off unit) and the newly independent company.

The word ‘spin-off’ captures the idea , a business is ‘spun off’ from the parent, sent off to operate on its own. The parent isn’t selling the unit to anyone; it’s separating it into an independent company and handing that company to its existing shareholders.

How a Spin-Off Works

The mechanics of a classic spin-off, at a high level:

1. A parent company decides one of its business units would be better as a separate, independent company
2. The unit is separated from the parent and established as a new, standalone company
3. The new company is set up to operate independently , its own structure, its own leadership
4. The parent distributes the shares of the new company to its own existing shareholders
5. Those shareholders now own two separate companies: the parent and the new spun-off company
6. The two companies operate independently from that point forward, each on its own

Why Companies Pursue Spin-Offs

Separating a perfectly functioning unit into its own company might seem counterintuitive. But companies pursue spin-offs for sound strategic reasons:

Unlocking Value

Sometimes a business unit’s value is obscured inside a larger, diversified parent , the market doesn’t fully recognize it. Separating it into its own independent company can let that value be seen and valued on its own. The idea is that two focused companies, separately, may be worth more than the one combined company.

Sharpening Focus

When a company contains two quite different businesses, neither may get full focus. A spin-off lets each business , the parent and the spun-off company , become a focused, standalone operation, with its own management fully dedicated to it.

Letting Distinct Businesses Stand on Their Own

Two businesses that don’t naturally belong together , different industries, different growth profiles, different needs , can each be better off independent. A spin-off lets each stand on its own rather than being constrained by being part of a mismatched whole.

Strategic Repositioning

A spin-off lets a parent reshape itself , separating out a business so the parent can focus on its core, while the spun-off company pursues its own path.

Spin-Off vs Carve-Out

A spin-off is often confused with a carve-out. Both separate a business unit from its parent , but they’re fundamentally different in one crucial way.

The Crucial Difference: Distribution vs Sale

The core distinction is this. A carve-out is a sale , the parent sells the business unit to a third-party buyer and receives cash. A spin-off is a distribution , the parent doesn’t sell the unit to anyone; it separates the unit into a new company and distributes that company’s shares to its own existing shareholders. A carve-out brings the parent cash from a buyer; a spin-off does not. One is a transaction with a buyer; the other sets the unit free as an independent company owned by the existing shareholders.

Spin-Offs, Carve-Outs, and Divestitures

Spin-offs and carve-outs are both part of a broader category: the divestiture. Understanding how the terms relate clears up common confusion.

A divestiture is the umbrella term for any way a company separates, disposes of, or sheds a business unit. It’s the general concept of a company getting a unit out of its portfolio.

Within that umbrella, there are different methods. A carve-out is one method , divesting a unit by selling it to a buyer. A spin-off is another method , divesting a unit by separating it into an independent company distributed to shareholders.

So a spin-off and a carve-out are two specific types of divestiture. Both achieve the same broad goal , separating a business unit from the parent , but by different means: a spin-off creates a new independent company; a carve-out sells the unit. When a company decides to divest a business, choosing between a spin-off and a carve-out (and other methods) is part of deciding how to do it.

What Happens After a Spin-Off

After a spin-off is complete, the picture is two separate companies where there was one.

The parent company. The parent continues , but now without the unit that was spun off. It’s a more focused company, concentrated on its remaining business, free of the unit that’s now independent.

The new company. The spun-off unit is now its own standalone, independent company. It operates on its own, with its own leadership, its own structure, and its own path forward , no longer part of a larger parent.

The shareholders. The parent’s original shareholders now hold shares in both companies , the parent and the new spun-off company. They own two separate businesses where they previously owned one combined company. The total they own is the same set of businesses, now held as two separate companies rather than one.

The bet behind a spin-off is that this separated structure , two focused, independent companies , creates more value, and serves each business better, than the single combined company did. Whether that proves true depends on how each company performs on its own.

What a Spin-Off Means for a Business Owner

For an owner of a private business, the spin-off is mostly relevant as context , it completes the picture of how companies separate businesses , but it also has a practical dimension.

A spin-off, in its classic public-company form, is a specific structure: separating a unit into an independent company and distributing its shares to existing shareholders. That precise mechanism is most associated with public companies with dispersed shareholders.

But the underlying idea , that a company might be better off separating a business unit so each part can stand on its own , applies to private companies too. A private-business owner whose company contains two quite different businesses might face a version of the same question: would these be better as separate companies? The owner could separate them, and the separated business could then be run independently, sold, or handled in various ways.

The most useful takeaway for a private-business owner is the broader concept. If you’re thinking about separating part of your business, understand the full menu: a spin-off (separating a unit into an independent company), a carve-out (selling a unit to a buyer for cash), and other forms of divestiture. If your goal is to get cash for a unit, a carve-out , a sale , is the path; a spin-off doesn’t bring proceeds. If your goal is to let two businesses stand on their own, separation is the path. Knowing how spin-offs, carve-outs, and divestitures relate helps an owner choose the right way to separate a business , and a competitive sale process is the way to maximize value if the goal is to sell a unit.

Conclusion

Notable Spin-Offs of 2023 to 2026: The Named Deals

The 2023 to 2026 window produced one of the densest spin-off cycles in two decades. GE finished dismantling itself with two separations. GE HealthCare separated on January 4, 2023, listing on Nasdaq under GEHC and taking the imaging, ultrasound, and patient care monitoring lines with it. Fifteen months later, on April 2, 2024, GE Vernova spun off as the standalone power and renewable energy business, leaving GE Aerospace as the rump engines company. The three-way break ended a corporate experiment that began in 1892.

3M ran the same play in 2024. On April 1 of that year, 3M completed the spin-off of Solventum, an $8 billion revenue healthcare business covering medical, dental, health information systems, and purification products. Solventum listed on the NYSE under SOLV and started life with about $8.4 billion of debt loaded onto its balance sheet by parent 3M, a common feature in tax-free separations.

Consumer staples saw Kellogg split into two on October 2, 2023. Kellanova kept the global snacks portfolio including Pringles, Cheez-It, Pop-Tarts, and the international cereal business. WK Kellogg Co inherited the North American cereal brands. Mars then announced a $35.9 billion acquisition of Kellanova in August 2024, validating the separation thesis within ten months.

Pharma joined in. Novartis spun off Sandoz, its generics and biosimilars unit, on October 4, 2023, listing the new company on the SIX Swiss Exchange. Sandoz arrived with about $7 billion in revenue and immediately ranked as the second largest generics maker in the world.

Other named separations in the window include Danaher’s October 2023 spin of Veralto, Johnson and Johnson’s August 2023 split-off of Kenvue, and Crane Holdings separating into Crane Company and Crane NXT in April 2023. The pattern is consistent: large conglomerates trading at sum-of-the-parts discounts elected to separate rather than wait for activists to force the move. For background on how separations differ from business combinations versus asset acquisitions, the structure choice drives every downstream tax and accounting decision.

Tax-Free Spin-Off Mechanics: Section 355 Requirements

Almost every meaningful spin-off in the United States is structured to qualify under Internal Revenue Code Section 355. A qualifying transaction delivers shares of the SpinCo to the parent’s shareholders without triggering corporate-level tax on the distribution and without triggering shareholder-level tax on receipt. The savings can run into the billions on a single deal.

Section 355 imposes five core requirements. First, the control test: the parent must distribute stock representing at least 80 percent of the voting power and 80 percent of each non-voting class of SpinCo. Second, the active trade or business test, often called the five-year ATB test: both the parent (RemainCo) and SpinCo must conduct an active trade or business that has been operated continuously for the five years preceding the distribution, and neither business can have been acquired in a taxable transaction within that window.

Third, the device test: the separation cannot be principally a device for distributing earnings and profits to shareholders, a rule meant to block disguised dividends. Fourth, the business purpose test: the transaction needs a real corporate business purpose beyond shareholder tax avoidance, with the IRS accepting reasons like fit and focus, resolving regulatory conflicts, facilitating an acquisition, or enabling separate equity compensation. Fifth, the continuity of interest test: the historic owners of the parent must retain meaningful continuity in both RemainCo and SpinCo after the separation.

Two additional traps sit on top of Section 355. The anti-Morris Trust rules under Section 355(e) impose corporate tax if 50 percent or more of either company’s stock is acquired as part of a plan within two years of the spin. The hot stock rule under Section 355(g) disqualifies the transaction if SpinCo holds investment assets that are 66 percent or more of its total assets.

Companies routinely obtain private letter rulings or tax opinions before pulling the trigger. The GE Vernova, GE HealthCare, Solventum, Kellanova, and Sandoz separations all relied on Section 355 qualification. A failed ruling would have added tens of billions in combined tax liability across those five deals alone. Spin-offs and recapitalizations both restructure capital, but Section 355 is what makes the spin path so attractive when it works.

Reverse Morris Trust: When a Spin Becomes a Sale

The Reverse Morris Trust, or RMT, is the structure companies use when they want to divest a business to a specific buyer without paying corporate tax on the gain. The mechanics layer Section 355 onto a merger. The parent spins off the unwanted business to its own shareholders, and immediately after the spin, SpinCo merges with a third-party acquirer. The catch is that the original parent’s shareholders must end up owning more than 50 percent of the combined post-merger entity, otherwise Section 355(e) triggers and the entire transaction becomes taxable.

The 50 percent threshold drives the deal math. The third-party acquirer is typically smaller than the spun-off business, because the spin shareholders need to swallow the combined company. This is the opposite of a normal acquisition where the buyer is larger. The buyer accepts dilution in exchange for picking up a sizable asset without the seller paying tax on the transfer, and the seller’s shareholders get tax-free liquidity into a more focused vehicle.

Named RMTs from the 2023 to 2026 window include Lockheed Martin’s prior pattern with its IT services business going to Leidos, and the structure has been used repeatedly by AT&T, Verizon, and Procter and Gamble for unit divestitures. AT&T’s WarnerMedia separation that combined with Discovery in April 2022 to form Warner Bros. Discovery is the largest recent RMT, with AT&T shareholders ending up with 71 percent of the combined entity.

The structure has clear limits. Two-year holding requirements bind both companies. The acquirer cannot quietly arrange to buy out the spin shareholders within 24 months. Activist investors sometimes attack RMT-eligible parents to force them to use the structure, because it releases value that a straight sale cannot match. The tax savings are real: a $10 billion divestiture at a 21 percent corporate rate plus state tax can save $2.5 billion or more compared with a taxable asset sale.

RMTs sit alongside straight spin-offs, horizontal mergers, and conventional divestitures as the four main paths to corporate separation, and the choice depends on whether a willing buyer exists at the right size. Sophisticated sellers run a dual-track process, soliciting RMT bids in parallel with taxable cash bids, and accept the RMT only when the after-tax proceeds clearly beat the cash alternative net of execution risk.

Spin-Off Performance Data: Do They Beat the Market?

The academic and practitioner data on spin-off returns is unusually consistent. The McKinsey study titled “Spin-offs as Catalysts of Renewal,” published in 2019, reviewed separations from 1992 through 2017 and found that the SpinCo outperformed the broader market by roughly 22 percent on a cumulative basis over the first 24 months after listing, while the RemainCo outperformed by about 13 percent over the same window. Combined, the parent and spin together delivered meaningfully higher returns than the pre-separation entity would have produced.

The Bloomberg US Spin-Off Index, which tracks US-listed companies for 24 months after they separate, has historically beaten the S&P 500 by 5 to 10 percentage points annualized across long stretches. The outperformance is not uniform. Spin-offs that are very small relative to the parent, that are heavily indebted at separation, or that face structural industry decline tend to underperform. The Solventum spin from 3M, for instance, traded down meaningfully in its first year because of the legal liabilities transferred and the debt load.

Several explanations show up repeatedly in the research. Management focus improves once a business is no longer subsidizing or being subsidized by an unrelated unit. Equity compensation works better when stock price reflects the actual business performance. Capital allocation discipline tightens because each company competes for capital on its own merits rather than at a parent-level allocation meeting. Activist pressure on the parent often forced the separation in the first place, meaning the easy cost cuts were already identified before the spin.

Forced sellers create a structural tailwind in the first few months. Index funds tracking the parent must sell the SpinCo shares because the new company does not yet meet index inclusion criteria. Active managers who held the parent often dump the spin without analyzing it. This creates a window of mispricing that quantitative strategies and dedicated spin-off funds try to capture. The advantages discussed in M&A advantages with examples have a mirror image in separations, where breaking up surfaces value the conglomerate structure suppressed.

Spin-Off Index Funds: The Investment Thesis

A small set of investment products exists specifically to capture spin-off outperformance. The Invesco S&P Spin-Off ETF, ticker CSD, is the most widely held. It tracks the S&P US Spin-Off Index, which holds US-listed companies that completed a spin within the past four years, weighted by float-adjusted market cap with a 4.5 percent single-stock cap. As of mid-2026, the fund holds roughly 35 names with assets around $100 million, an expense ratio near 0.65 percent, and rebalances quarterly.

The investment thesis rests on three observations. First, the forced selling at separation creates near-term price pressure that fades within months as natural holders accumulate the new shares. Second, management incentives reset at the spin, with fresh equity grants tied to the standalone company’s performance. Third, the SpinCo is often a business the parent under-invested in, meaning operational improvements are available without heroic assumptions.

The strategy has limits. The investible universe shrinks in years when separations slow, and the fund can run concentrated in two or three large recent spins. The four-year holding window means CSD currently owns GE Vernova, GE HealthCare, Solventum, Kellanova, WK Kellogg, Veralto, Kenvue, and Sandoz among its larger positions from the 2023 to 2026 cycle. Performance versus the S&P 500 has been positive over multi-year windows but with higher volatility, because spins skew toward mid-cap industrial and healthcare names rather than large-cap tech.

Dedicated spin-off hedge funds and separately managed accounts use the same playbook with more flexibility. They can short the parent if they believe RemainCo is overvalued post-spin, hold the SpinCo longer than four years, or concentrate into the most asymmetric situations. Joel Greenblatt’s 1997 book “You Can Be a Stock Market Genius” popularized the strategy among value investors and remains the standard reference. For investors, spin-offs are one of the few corporate event categories with a documented and persistent return premium, and the CSD ETF provides the cheapest passive access to the trade. Position sizing matters because a single failed spin like a debt-heavy SpinCo in a declining industry can offset gains from three or four successful separations, so the index approach tends to outperform concentrated bets over full cycles.

Frequently Asked Questions

What is a spin-off?

A spin-off is a corporate action in which a parent company separates one of its business units into a brand-new, independent company. In a classic spin-off, shares of the new company are distributed to the parent’s existing shareholders.

How does a spin-off work?

A parent company separates a business unit into a new standalone company, sets it up to operate independently, and distributes the shares of the new company to its own existing shareholders. Those shareholders then own two separate companies , the parent and the spun-off company.

Does a spin-off bring cash to the parent company?

No. A spin-off is a distribution, not a sale. The parent doesn’t sell the unit to a buyer , it separates the unit into an independent company and distributes its shares to existing shareholders. No buyer, no proceeds. (A carve-out, by contrast, is a sale that does bring cash.)

Why do companies pursue spin-offs?

To unlock value (a unit’s value can be obscured inside a larger parent), sharpen focus (each business becomes a focused standalone operation), let distinct businesses stand on their own, and strategically reposition the parent around its core.

What’s the difference between a spin-off and a carve-out?

A spin-off separates a unit into a new independent company and distributes its shares to the parent’s existing shareholders , a distribution, no buyer, no cash. A carve-out sells the unit to a third-party buyer for cash , a sale. The crucial difference is distribution versus sale.

Is a spin-off a type of divestiture?

Yes. Divestiture is the umbrella term for any way a company separates or sheds a business unit. A spin-off is one method of divestiture (creating an independent company); a carve-out is another (selling the unit to a buyer).

What happens to shareholders in a spin-off?

In a classic spin-off, the parent’s existing shareholders receive shares of the new spun-off company , they don’t pay for them. After the spin-off, they own shares in two separate companies: the parent and the new independent company.

What happens to the parent company after a spin-off?

The parent continues, but without the unit that was spun off. It becomes a more focused company, concentrated on its remaining business, free of the unit that is now an independent company.

What’s the difference between a spin-off and a sale?

A sale transfers a business to a buyer in exchange for payment. A spin-off doesn’t involve a buyer or a payment at all , it separates a unit into an independent company and distributes that company to the parent’s existing shareholders. A spin-off is a distribution, not a sale.

Why would a company give away a business unit in a spin-off?

It’s not giving it away to outsiders , the spun-off company goes to the parent’s own existing shareholders. The strategic bet is that two focused, independent companies create more value, and serve each business better, than the single combined company did.

Can a private company do a spin-off?

The classic spin-off mechanism , distributing shares to dispersed public shareholders , is most associated with public companies. But the underlying idea of separating a business unit so each part can stand on its own applies to private companies too, through various separation structures.

Spin-off or carve-out , which should I choose for separating a unit?

It depends on the goal. If you want cash for the unit, a carve-out , a sale to a buyer , is the path; a spin-off brings no proceeds. If the goal is to let two businesses stand on their own independently, separation via a spin-off-style structure fits. The goal determines the method.
