Promoter Lock-In Before an IPO: The Cap Table Problems to Fix Early

In short: promoters must hold at least 20 per cent of the post-issue paid-up capital, and that block is locked in for 18 months from allotment — three years where more than half the fresh issue proceeds fund capital expenditure. Only eligible shares count towards the 20 per cent, and pledged shares, bonus shares from revaluation reserves and non-cash acquisitions in the preceding three years generally do not.

Most promoters approaching an IPO treat promoter lock-in as a post-listing inconvenience: shares frozen for a while, then free. The problem usually surfaces earlier and costs more. Six weeks before a DRHP is filed, the merchant banker runs the cap table and finds that a meaningful slice of the promoter's holding is not eligible to count towards the minimum promoters' contribution. At that stage, the fixes are slow and expensive.

The 20 per cent that has to be genuinely yours

Under the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018, promoters must hold at least 20 per cent of the post-issue paid-up capital. This applies to mainboard issues and to SME issues on BSE SME and NSE Emerge. The requirement is not about total promoter shareholding; it is about eligible shareholding. Those are two different numbers, and the gap between them is where transactions come unstuck.

Shares that do not count towards the contribution

The ICDR Regulations exclude several categories from the computation. In broad terms:

• Shares pledged with any creditor

• Shares acquired in the three years before filing for consideration other than cash, or arising from a revaluation of assets or capitalisation of intangibles

• Bonus shares issued out of revaluation reserves or unrealised profits

• Shares acquired in the preceding year below the issue price, subject to specified exceptions

Two of these bite most often in owner-managed companies. Promoters routinely pledge shares as collateral for working capital limits, and family businesses routinely issue bonus shares or swap holdings during group restructurings without documenting a commercial rationale. Both are ordinary decisions in an unlisted company. Both create an eligibility hole at the IPO.

Promoter lock-in periods: how long the shares stay frozen

• Minimum promoters' contribution: 18 months from the date of allotment, extended to three years where more than half the fresh issue proceeds are applied towards capital expenditure

• Promoter holding in excess of the minimum contribution: 50 per cent released after one year, the balance after two years

• Pre-issue capital held by persons other than promoters: six months from allotment

The capital expenditure extension deserves attention at the planning stage rather than the drafting stage. A company raising primarily to fund a new plant is choosing a three-year freeze on its core promoter block. Where a promoter has a foreseeable personal liquidity requirement, such as an estate settlement or the buyout of a dissenting family shareholder, the objects of the issue and the promoter's own plans should be reconciled long before the DRHP is drafted. The staggered release of above-minimum holdings was among the changes covered in SEBI's 2025 SME IPO rule changes.

The pledge question

Locked-in shares can, in defined circumstances, be pledged as collateral to scheduled commercial banks or public financial institutions, but generally only where the pledge is a term of the sanction and the borrowing funds the objects of the issue. Pledges created for ordinary working capital limits will not qualify. Releasing and re-documenting a pledge takes months once a lender is involved, which is why the cap table clean-up should begin before the merchant banker's due diligence, not during it.

SEBI also amended the framework in March 2026 to deal with pledged pre-issue shares held by non-promoters, broadly requiring depositories to mark such shares non-transferable for the lock-in period rather than relaxing the restriction. Companies with pledged pre-IPO investor shares should confirm the current operational mechanics with their depository participant and counsel.

A practical sequence, twelve to eighteen months out

• Map every promoter and promoter-group holding by date, mode and consideration of acquisition

• Identify shares acquired otherwise than for cash and document the commercial rationale contemporaneously

• Plan the release of pledges over the block intended to serve as the minimum contribution

• Model post-issue capital at the intended dilution and confirm the eligible promoter block still clears 20 per cent

None of this is difficult work. It is simply work that cannot be compressed into the weeks before a filing, which is why it belongs in the earliest phase of an IPO readiness timeline. Companies still weighing the routes should start with SME IPO versus mainboard IPO, and check the underlying mainboard eligibility criteria or SME eligibility criteria, since the chosen route affects the lock-in profile.

Common questions

What is minimum promoters' contribution? At least 20 per cent of the post-issue paid-up capital, held by the promoters, under the SEBI ICDR Regulations, 2018. It applies to mainboard issues and to SME issues on BSE SME and NSE Emerge.

How long is the promoter lock-in period? Eighteen months from allotment for the minimum contribution, or three years where more than half the fresh issue proceeds fund capital expenditure. Holding above the minimum releases 50 per cent after one year and the balance after two. Non-promoter pre-issue capital is locked in for six months.

Which shares are ineligible? Broadly, shares pledged with any creditor; shares acquired in the preceding three years for consideration other than cash or from revaluation of assets or capitalisation of intangibles; bonus shares from revaluation reserves or unrealised profits; and shares acquired in the preceding year below the issue price, subject to specified exceptions.

Can locked-in shares be pledged? Only narrowly — to scheduled commercial banks or public financial institutions, generally where the pledge is a term of the sanction and the borrowing funds the objects of the issue. Working capital pledges do not qualify.

A note on getting this right

Cap table eligibility is one of the few IPO workstreams that cannot be accelerated late in the process, and it sits at the intersection of accounting records, security documentation and securities regulation. Companies in the Rs 100 crore to Rs 1,000 crore band, whether they are considering the mainboard or an SME platform, generally benefit from mapping this position with their auditors and advisers a full financial year before a filing is contemplated.
