Spin-off, split-off and equity carve-out describe different movements of shares and money. The quickest way to distinguish them is to ask: who receives subsidiary shares, does anyone surrender parent shares, and who receives cash?

This confusion is visible in a finance-study discussion and a shareholder’s question about a split-off versus a demerger. Memorising three similar labels is less useful than drawing the ownership before and after.

For CISI MAMR, the comparison supports Disposals and Demergers. Split-off terminology is included as a practical contrast from issuer documents, not as a claim that it is a separate syllabus chapter.

Spin-off vs split-off vs carve-out in one table

Route	Who receives subsidiary shares?	What happens to parent shares?	Does the basic step raise investor cash?
Spin-off	Existing parent shareholders through a distribution	They normally keep them	No
Split-off	Shareholders whose exchange tenders are accepted	Accepted parent shares are surrendered	Not through the share-for-share exchange itself
Equity carve-out	Outside investors buying or subscribing	Existing parent holdings are not automatically exchanged	Yes, with the recipient depending on the shares sold or issued
Trade sale	A buyer acquires the business or subsidiary	Parent shareholders do not automatically receive subsidiary shares	The seller receives the agreed consideration

These describe the basic mechanics, not every associated financing or tax step. A transaction can use more than one route over time.

Spin-off: keeping the parent and receiving the subsidiary

Suppose you hold 200 shares in Parent P. P distributes one share in Subsidiary S for every four P shares. With no other corporate action, you now hold 200 P shares and 50 S shares.

The group has changed how you hold the businesses. You did not buy S shares in the market, and the distribution itself did not raise new investor money for P.

A real illustration is GSK’s separation of Haleon. Its official shareholder explanation described one Haleon share for each GSK share. GSK also undertook a separate share consolidation, so do not apply the simple hypothetical holding above to that actual transaction without reading both steps.

The exam implication is immediate: a plain spin-off is not the direct answer to “the parent urgently needs cash sale proceeds”. A wider separation may contain a financing transaction, but that must be identified separately.

Split-off: an exchange, not an extra gift

In a split-off, participating investors surrender accepted parent shares in return for subsidiary shares.

Take a simplified exchange: you own 100 P shares, tender 40, and all 40 are accepted for 120 S shares. You finish with 60 P shares and 120 S shares. Keeping all 100 P shares as well would double-count the shares you surrendered.

Johnson & Johnson’s Kenvue exchange-offer announcement allowed shareholders to tender some, all or none of their J&J holdings, subject to the offer terms. Its final results show why those terms matter: oversubscription led to proration, with a specified exception.

A tender is therefore not a guarantee that every submitted share will be exchanged. Check eligibility, ratio, deadlines and proration in the actual documents. The example illustrates ownership mechanics, not a recommendation to participate in an exchange.

Equity carve-out: follow the cash recipient

A carve-out introduces investors into the subsidiary, commonly through a partial flotation. The parent may retain a significant or controlling stake.

Now distinguish two funding paths:

• The parent sells existing subsidiary shares. Sale proceeds go to the parent, before costs and any subsequent transfers.
• The subsidiary issues new shares. Subscription proceeds go to the subsidiary. They do not automatically become cash available in the parent’s bank account.

Suppose the parent sells existing shares for £45 million and incurs £2 million in selling costs. On those assumptions, net proceeds are £43 million. If instead investors subscribe £30 million for newly issued subsidiary shares, that £30 million initially funds the subsidiary.

This distinction matters when a question asks whether a transaction can repay parent debt. “An IPO raises money” is incomplete: identify the issuing or selling entity first.

Kenvue also demonstrates that a separation can be staged: its IPO preceded the later shareholder exchange. Do not force a multi-step transaction into one label and ignore its sequence.

Why more share certificates do not mean free value

A spin-off can leave an investor holding shares in two quoted businesses instead of one. That is not, by itself, an increase in total economic value.

In a deliberately simplified illustration, a £1,000 parent holding contains £250 attributable to the business being separated. Ignore costs, debt changes and market repricing. After separation, the comparison is £750 of remaining-parent value plus £250 of subsidiary value, not £1,000 plus £250.

Actual prices need not follow that arithmetic exactly. Separate management, funding choices, lost shared services, transaction costs and the market’s assessment can change value. The point is to avoid counting the same business twice.

Similarly, selling a profitable division is not automatically irrational. Profitability is one fact; strategic fit, capital needs and the costs of running the businesses together or apart also matter.

Solve a disposal case by tracing three movements

For an unfamiliar transaction, write three short answers:

1. Shares received: existing owners, tendering owners, public subscribers or one buyer?
2. Shares surrendered: none, accepted parent shares, or the parent’s subsidiary stake?
3. Cash received: parent, subsidiary, selling shareholders, or nobody in that step?

Then test the stated objective. A parent seeking liquidity needs a credible cash route. A distribution aimed at separate ownership needs a workable separation. A retained majority requires attention to the relationship with outside shareholders.

Finally, isolate any borrowing, dividend, tax, liability or service-agreement step rather than attributing it automatically to “demerger”. Tax outcomes depend on the actual structure and jurisdiction; the labels alone do not establish tax-free treatment.

The 15 original questions above practise these distinctions. For assessment format and planning, use the existing MAMR exam guide. For the full five-element course, including disposals and linked transaction cases, see Exams Academy’s CISI MAMR preparation.
