How to understand SEBI's takeover code guidelines

What happens when one company tries to take over another listed Indian company? The first thing that triggers is not a press release or a phone call to shareholders — it is the SEBI Takeover Code. What is SEBI in plain words: the market regulator that writes the rules companies must follow when control changes hands. The Takeover Code is the rulebook for one of the most disruptive moments in any listed firm's life.

If you own shares, you should understand it. The code decides whether you get a fair exit, what price you receive, and how much warning you get.

What is the SEBI Takeover Code

Officially the Securities and Exchange Board of India Substantial Acquisition of Shares and Takeovers Regulations, 2011, it lays out:

• When an acquirer must publicly announce a takeover.
• How much they must offer to buy from public shareholders.
• The price floor and timeline for that offer.
• What disclosures must be made to the exchanges and SEBI.

The intent is simple. Public shareholders should never be left holding shares while a quiet change of control happens behind the scenes.

The two trigger thresholds

Most of the rulebook hinges on two numbers.

1. 25 percent — when an acquirer's holding crosses this, they must make an open offer to buy at least 26 percent more from public shareholders.
2. Creeping acquisition above 25 — once above 25 percent, an acquirer can buy up to 5 percent more in a financial year without triggering an offer. Cross that and the offer obligation kicks in again.

These numbers exist because once a single party owns more than a quarter of a listed company, their decisions begin to drive the company materially.

Step 1 — Spot the trigger event

The trigger can be direct purchase from the open market, an off-market block deal, a preferential allotment, or even an indirect change like a holding company takeover. The form does not matter. The substance does — did anyone breach 25 percent or buy more than 5 percent in a year above that?

Step 2 — Read the public announcement

Within four working days of the trigger, the acquirer files a public announcement. This is the first official sign for shareholders. It states:

• Identity of the acquirer.
• Number of shares held before and after the trigger.
• Reason for the acquisition.
• Indicative open offer price.

The announcement appears on stock exchange filings. Pay attention to the name behind the acquisition. Sometimes it is a strategic operator. Sometimes a financial buyer. The intent shapes what happens next.

Step 3 — Understand the open offer mechanics

The open offer is the heart of the code. Key features:

• Minimum offer size of 26 percent of the target company.
• Open to all public shareholders, not just selected ones.
• Floor price calculated using the highest of three formulas — recent acquisition price, 60-day volume-weighted average, or other regulator-defined benchmarks.

Shareholders tender their shares if they want to exit. If more shares are tendered than the offer size, the acquirer accepts on a proportionate basis.

Step 4 — Read the letter of offer

The letter of offer is sent to all eligible shareholders. It contains the formal offer price, the timeline, the procedure, and the validity window. This document is dense but worth reading. Look at:

1. The offer price compared to current market price.
2. The intent stated by the acquirer — control change, restructuring, delisting later.
3. Any conditional clauses such as minimum acceptance.
4. The window for tendering shares.

Real example: in 2022, a global packaging giant launched an open offer for an Indian listed peer at a price 12 percent above the 60-day average. Retail shareholders who tendered locked the gain. Those who did not held shares that drifted back to original levels.

Step 5 — Decide whether to tender

The decision is not automatic. Three considerations help:

• Premium — how much above current market price is the offer?
• Future story — will the new owner add value or strip the business?
• Liquidity — will minority holders find decent volumes after the offer?

If the premium is small and the new owner has a strong track record of value creation, holding may pay off. If liquidity is likely to drop and you wanted out anyway, tendering captures a controlled exit.

Step 6 — Watch for delisting hints

Sometimes an open offer is the first step toward delisting. Once the acquirer's stake crosses 90 percent, they can launch a delisting offer at a separate, often higher, price. If you see clues — small public float, related-party operations, low promoter dilution — the journey may not end with the takeover offer.

Common shareholder mistakes

• Ignoring the announcement because the company name does not change immediately.
• Tendering too late — submissions after the close are rejected with no exception.
• Confusing the open offer price with future fair value of the share.

FAQs

Is the open offer price always above market price?

It is the higher of several formulas, so usually yes. But during volatile markets, the offer price can drift below the prevailing market price.

What happens if I do not tender?

You keep your shares. Liquidity may shrink and the new owner's actions will then drive your future returns.

Can the acquirer withdraw an open offer?

Only in narrow circumstances such as failed regulatory approvals. Routine withdrawals are not allowed.
