Demergers, Restructuring and the M&A Legal Framework

Updated 11 October 2026 · Fact-checked

A demerger transfers one or more undertakings of a company to another company, with shareholders usually receiving shares of the new entity. You solve questions by identifying the restructuring type, applying the right approval route (Companies Act scheme, SEBI Takeover Code, CCI), and then computing shares or value split as asked.

Understand Demergers, Restructuring and Legal Framework

Restructuring means changing the structure of a business to unlock value. It includes mergers, acquisitions, demergers, spin-offs, divestitures, slump sales and buy-backs. Valuers are asked which route creates most value and what approvals it needs.

A demerger moves one or more undertakings of a company (the demerged company) into another company (the resulting company). Under a court/NCLT-approved scheme, the shareholders of the demerged company receive shares of the resulting company, usually in proportion to their holding. The original company continues to exist. The conditions in the Income-tax Act, 2025 give tax-neutral treatment to a demerger only if the scheme meets them, so check the conditions before claiming it.

A spin-off is a demerger in which the resulting company's shares are distributed pro rata to the existing shareholders, with no exchange of parent shares, so ownership mirrors the parent and no cash comes in. In a split-off, shareholders surrender some of their parent shares in exchange for shares of the new entity, so holdings in the new entity are not pro rata to their holdings in the parent. A divestiture (or slump sale) is a sale of a unit to a buyer for cash or other consideration; the seller receives the money, not its shareholders. A carve-out sells a minority stake of a subsidiary to the public while the parent keeps control.

Three regulators matter. The Companies Act, 2013 governs schemes of compromise, arrangement, merger and demerger through the NCLT: board approval, application to NCLT, meetings of shareholders and creditors where ordered, notice to regulators, NCLT sanction, filing the order with the Registrar. A fast-track merger under Section 233 of the Companies Act, 2013 is available for specified classes such as small companies, mergers of a holding company with its wholly owned subsidiary, and mergers of start-up companies. The scheme must first be approved by members holding at least 90% of the total number of shares and by creditors, or a class of creditors, representing nine-tenths in value. Notice of the scheme goes to the Registrar and the Official Liquidator, and the scheme is then approved by the Central Government (through the Regional Director) without an NCLT hearing. If the Central Government believes the scheme is not in the public interest or in the interest of creditors, it may instead refer the scheme to the NCLT.

The SEBI (SAST) Regulations, 2011 (Takeover Code) apply to listed targets. A mandatory open offer to public shareholders arises when an acquirer acquires shares or voting rights which, taken together with the holding of the acquirer and persons acting in concert, entitle them to exercise 25% or more of the voting rights, or when the acquirer acquires control. The minimum offer size is 26% of the target's total shares. The CCI reviews combinations above the asset or turnover thresholds under the Competition Act, 2002, and a combination cannot take effect until approved or the statutory period lapses. Listed company schemes also need SEBI/stock exchange no-objection, so cover all regulators in your answer.

Key rules to remember

Share entitlement in a demerger (pro rata): New shares to a holder = Shares held in demerged company × Entitlement ratio; Example: ratio 1:2 means 1 resulting-company share for every 2 held. Fractions are usually rounded or settled in cash as per the scheme.
Value of demerged entity: Value of remaining business = Pre-demerger equity value − Value of undertaking demerged; Total shareholder wealth should be unchanged immediately before and after if both are valued fairly.
Open offer trigger and size (SEBI SAST): Trigger: acquirer, with persons acting in concert, acquiring shares that take voting rights to 25% or more, or acquiring control. Minimum open offer = 26% of total shares of the target; State the thresholds exactly as the Regulations provide for the case, and note creeping acquisition rules separately.
Open offer price (principle): Offer price = highest of the specified benchmarks (negotiated price, volume-weighted averages and other prescribed prices); Do not use only the latest market price. Use the figures the question gives.
Post-restructuring value check: Value created = Sum of parts after restructuring − Value before restructuring; Positive only if standalone value of parts exceeds the conglomerate value, net of costs.

How to solve Demergers, Restructuring and Legal Framework questions

Use this order for both theory and numerical questions on restructuring and legal procedure.

1Identify the transaction: merger, demerger, spin-off, split-off, divestiture, carve-out or open offer.
2Note who receives consideration: shareholders (demerger, spin-off) or the company (divestiture, slump sale).
3List the approvals: board, shareholders and creditors, NCLT, SEBI and stock exchanges for listed companies, CCI if thresholds are crossed, Registrar filings.
4If listed target is bought, test the SEBI SAST triggers (25% or control) and compute the open offer size and price from the data given.
5For numbers, value the whole, value the part demerged, then split between shareholders using the stated ratio.
6Check that shareholder wealth is unchanged before and after, ignoring costs unless given.
7Write a recommendation: why the structure creates value (focus, clarity, valuation gap) and the main legal risk.

Quickest way: Type, regulator, number

When to use it: Use in 14-mark case answers or MCQs where time is short.

Underline the structure and who gets paid.
Write the regulator list in one line: NCLT, SEBI, CCI as applicable.
Do the arithmetic in a small table: before, demerged part, remaining, shares issued.
Close with one line of recommendation.

Common mistakes in Demergers, Restructuring and Legal Framework

Treating a demerger and a divestiture as the same.
Both remove a business from the company.
Fix: In a demerger, the shareholders get shares of the resulting company. In a divestiture, the company gets the sale proceeds.
Saying the original company disappears after a demerger.
Confusing it with an amalgamation.
Fix: The demerged company continues with its remaining business. Only the undertaking moves.
Applying the 25% open offer trigger to unlisted companies.
Remembering the number but not the scope.
Fix: The Takeover Code applies to listed targets. For unlisted companies the Companies Act procedure applies.
Ignoring CCI when the deal is large.
Students focus on NCLT and SEBI only.
Fix: Add a line: check whether the combination crosses the CCI thresholds and seek approval before completion.
Calculating the open offer as 26% of the shares being bought.
Misreading the base.
Fix: Take 26% of the target's total shares, as the Regulations specify, not of the acquirer's purchase.

Worked examples

Example 1

Alpha Industries Ltd has equity value ₹900 crore and 10 crore shares. It demerges its chemicals division, valued at ₹300 crore, into Beta Chemicals Ltd. Beta issues 1 share for every 2 Alpha shares. Mr. Rao holds 1,000 Alpha shares. Find value of the remaining Alpha, shares Mr. Rao gets, and value of his holding in each company (assuming value per share changes only through the split of value).

Show the solution

Value per Alpha share before demerger = ₹900 crore ÷ 10 crore = ₹90.
Value of remaining Alpha = ₹900 crore − ₹300 crore = ₹600 crore.
Alpha value per share after demerger = ₹600 crore ÷ 10 crore = ₹60.
Beta shares issued = 10 crore ÷ 2 = 5 crore shares.
Beta value per share = ₹300 crore ÷ 5 crore = ₹60.
Mr. Rao gets 1,000 ÷ 2 = 500 Beta shares.
Value of Alpha holding = 1,000 × ₹60 = ₹60,000. Value of Beta holding = 500 × ₹60 = ₹30,000.
Total = ₹90,000. Before demerger, 1,000 × ₹90 = ₹90,000, so wealth is unchanged.

Answer: Remaining Alpha is worth ₹600 crore. Mr. Rao gets 500 Beta shares. His holdings are ₹60,000 in Alpha and ₹30,000 in Beta, total ₹90,000, same as before.

Example 2

Sunrise Ltd, a listed company with 5,00,00,000 shares, is being acquired by Meridian Ltd, which holds 20% and agrees to buy a further 10% from the promoters at ₹200 per share. Advise on the SEBI Takeover Code, the minimum open offer size, and the other approvals needed.

Show the solution

Meridian's holding after purchase = 20% + 10% = 30%, which takes it past 25% of the voting rights.
The agreement to buy the 10% is itself the trigger. An open offer to public shareholders is therefore mandatory, and the public announcement must be made when the agreement is entered into, not after the purchase is completed.
Minimum open offer = 26% of total shares of the target = 26% × 5,00,00,000 = 1,30,00,000 shares. This is 26% of Sunrise's total shares, not of the 10% being bought.
Offer price must be the highest of the prescribed benchmarks. The ₹200 negotiated price is one of them, not the floor by itself, so the offer price is at least ₹200 and higher if any other benchmark (for example the volume-weighted average market price) is above ₹200.
The ₹260 crore outlay holds only if ₹200 is the highest benchmark. In that case, minimum offer cost = 1,30,00,000 × ₹200 = ₹2,60,00,00,000 = ₹260 crore. If another benchmark is higher, the outlay is 1,30,00,000 × that higher price.
Check CCI: if the combination crosses the asset or turnover thresholds, approval is needed before completion.
Complete the disclosures to SEBI and stock exchanges as per the Regulations.

Answer: Meridian triggers a mandatory open offer, with the public announcement made on the agreement to acquire. The minimum offer size is 1,30,00,000 shares (26% of total shares). The offer price is the highest of the prescribed benchmarks; only if ₹200 is the highest is the minimum outlay ₹260 crore (₹2,60,00,00,000). CCI approval is also needed if thresholds are met.

Exam tips

Draw a one-line table for demerger numbers: before, demerged, remaining, shares issued. It earns method marks even if you slip on arithmetic.
In theory answers, list the regulators separately: NCLT, SEBI, CCI. Examiners look for all three.
For MCQs, check who receives the consideration to separate demerger from divestiture quickly.
State percentages in the Takeover Code exactly (25% trigger, 26% minimum offer) and apply them to total shares of the target.
End case answers with a clear recommendation on value creation and legal feasibility.

Demergers, Restructuring and Legal Framework: frequently asked questions

What is the difference between a demerger and a spin-off?

A demerger is the broad term for transferring an undertaking to another company under a scheme. A spin-off is one form of it: the resulting company's shares are distributed pro rata to the existing shareholders with no exchange, so the parent's shareholders own both companies in the same proportion. In a split-off, shareholders instead surrender some parent shares in exchange for shares of the new entity, so their holdings are not pro rata.

When is an open offer required under the SEBI Takeover Code?

When an acquirer, with persons acting in concert, acquires shares which, with existing holding, entitle them to exercise 25% or more of the voting rights in a listed company, or when the acquirer acquires control. The minimum offer is for 26% of the target's total shares. Check the Regulations for exemptions and for creeping acquisition.

What is the NCLT procedure for a merger?

The board approves the scheme, then the companies apply to the NCLT. The NCLT may order meetings of shareholders and creditors, notice goes to regulators, and the Tribunal sanctions the scheme. The order is then filed with the Registrar. Fast-track merger under Section 233 applies to specified classes such as small companies, holding and wholly owned subsidiary mergers, and start-up mergers. It needs approval by members holding at least 90% of the total number of shares and by creditors representing nine-tenths in value, and is then approved by the Central Government (Regional Director) without an NCLT hearing, but the Central Government may refer the scheme to the NCLT if it is not in the public interest or the interest of creditors.

Does a demerger change shareholder wealth?

Not on its own. Value is split between the two companies, so total wealth stays the same at the point of demerger. Value gains come later from focus, better capital allocation or removing a conglomerate discount.
