Divestiture and spin-off
Examples checked
In one minute
Selling a business, or splitting it off as its own company.
The big idea: A business is worth more where it is run best. If the market values a group at less than its parts, or a unit needs a different kind of owner, selling it or spinning it off can create value, as long as the separation costs and lost shared costs are smaller than the gain.
- Works when
- When the businesses share little, need different strategies or investors, and the parts are clearly worth more apart.
- Fails when
- When the units shared real costs or customers, separation is costly, or the business is sold cheap in a hurry.
- Check this number first
- Value of each part on its own. Profit times what similar companies are valued at.
- In the worked example
- Value of the parts after the split: USD 1,790 (USD millions of value). See it add up
What it is
A divestiture is selling a business to another owner. A spin-off (or demerger) makes a business a separate listed company owned by the same shareholders. A carve-out sells part of a business's shares to the public. Companies do this to focus, to raise cash, or because the parts are worth more apart.
- Sale. Sell to a buyer for cash; often to a rival or a private equity firm.
- Spin-off or demerger. Shareholders get shares in the new company; no cash comes in.
- Carve-out. List part of the business on the stock market and keep the rest.
Why companies do it
The economic logic, most important first. A move usually rests on one or two of these.
- Focus. Each business gets management attention and a strategy that fits it.
- Capital efficiency. Each business can be funded the way it needs, with debt for steady units and equity for growth units.
- Growth. A unit starved of investment inside a group may grow faster on its own or with a new owner.
When it creates value, and when it destroys it
Creates value when
- The market values the group below the sum of its parts.
- The units have different growth, risk or capital needs, and different investors want them.
- Little is shared, so separation costs are small.
- A buyer can run the unit better, and pays for it.
Destroys value when
- Shared costs and customers were real, and each part now pays more.
- Separation costs (systems, people, contracts) are larger than planned.
- The business is sold in a hurry, at a low price.
- The remaining company is too small to compete.
The numbers to check
Ask for these, in this order, before you recommend the move.
- Value of each part on its own. Profit times what similar companies are valued at.
- Group market value today. The gap shows the conglomerate discount.
- One-off separation costs. Advisers, systems, new boards.
- Extra running costs after the split (dis-synergies). Two head offices, two sets of systems.
Worked example (illustrative)
Rounded numbers for a made-up business, shaped like real ones. Positive lines add to profit; negative lines are costs.
A group has a fast-growing unit earning USD 100 million a year and a slow unit earning USD 50 million. Similar companies trade at 15 and 8 times profit. The group is worth USD 1,600 million on the market.
| Line | USD millions of value |
|---|---|
| Fast unit on its own: USD 100 million x 15 | USD 1,500 |
| Slow unit on its own: USD 50 million x 8 | USD 400 |
| One-off costs of separating (advisers, systems) | minus USD 60 |
| Extra yearly cost of two head offices, valued at 10 times: USD 5 million x 10 | minus USD 50 |
| Value of the parts after the split | USD 1,790 |
Check: the lines above add up to the total.
The numbers that decide it
- Value gained against today's USD 1,600 million
- USD 190
- Value gained as a share of today's value
- 11.9 percent
So what: The two parts are worth about USD 1,790 million apart, after costs, against USD 1,600 million together: a gain of about 12 percent. The gain exists because the group is valued as if both units were slow. If the split costs twice as much, the gain shrinks but stays positive.
Real examples
Companies that made this move, by region, with what happened and a source checked on the date shown.
General Electric
United StatesToo early to tellGE split into three listed companies: GE HealthCare was spun off in January 2023, and GE Vernova (energy) in April 2024, leaving GE Aerospace. Shareholders received one GE Vernova share for every four GE shares.
The lesson: Businesses with different customers, cycles and investment needs can be valued and run better apart.

Unilever (The Magnum Ice Cream Company)
EuropeToo early to tellUnilever demerged its ice cream business as The Magnum Ice Cream Company; the demerger completed on 6 December 2025, with trading in the new shares due to start in Amsterdam, London and New York two days later.
The lesson: Ice cream needs freezers, cold chains and seasonal planning that the rest of the group does not, which made it a natural business to separate.

Tata Motors
IndiaToo early to tellTata Motors split its commercial vehicle business into a separately listed company, giving shareholders one new share for each share held; the scheme took effect on 1 October 2025.
The lesson: Trucks and passenger cars face different buyers and cycles, so each can now be run and valued on its own terms.

Uber (Southeast Asia sale to Grab)
Southeast AsiaMixedUber sold its Southeast Asian business to Grab in 2018 for a 27.5 percent stake. Singapore's competition regulator found that fares rose 10 to 15 percent afterwards, with Grab holding about 80 percent of the market, and fined the two firms.
The lesson: Selling to your main rival can end losses, but competition regulators may step in when the buyer ends up with most of the market.

How to recommend it in a case
Answer first, then the reasons with numbers, then the risk and the next step. Three sentences, said out loud.
I recommend spinning off the fast-growing unit, because the parts are worth about USD 1,790 million apart against USD 1,600 million today, a gain of about 12 percent.
The market values the whole group like the slow unit; on its own the fast unit can be valued at 15 times profit, and the two share little beyond a head office.
The risk is that separation costs run over the USD 60 million plan; next I would list every shared system and contract and decide which unit keeps each.
The numbers to quote: Value of each part; Group value today; Separation costs; Extra yearly costs after the split.
The figures in the answer come from the illustrative worked example above. In a case, use the client's own numbers.
Classic interview traps
- Assuming parts are always worth more apart. Only if the market undervalues the group, or a new owner runs a unit better.
- Forgetting dis-synergies: shared costs become duplicate costs.
- Mixing up a sale (cash comes in) and a spin-off (no cash, shareholders get new shares).
