Migrating from BSE SME or NSE Emerge to the Main Board: A Promoter's Guide

A few years after an SME listing, the question almost always comes up in a board meeting: should we move to the main board? The stock has a track record, revenue has grown, and someone has heard that main board companies get better valuations and institutional interest. Sometimes that is true. Sometimes the company would be better off staying exactly where it is for another two or three years. Migration is not a reward for good behaviour on the SME platform. It is a change of regulatory regime, with a real compliance bill attached, and it should be decided on that basis.

This piece walks through how migration from BSE SME or NSE Emerge to the main board actually works: who is eligible, the steps, how long it takes, what it costs, what changes the day after, and how I think about whether a company should go at all. If you are still at the stage of choosing a platform for the IPO itself, start with my founder’s guide to the SME IPO and my comparison of BSE SME and NSE Emerge.

What migration is, and what it is not

Migration moves your existing, already-listed shares from the SME platform of an exchange to its main board. No new shares are issued as part of the migration itself, no money is raised, and no one is diluted. There is no DRHP, no price band and no book build. What changes is the market your shares trade in and the set of rules the company has to live by afterwards.

That distinction matters because promoters sometimes treat migration as a second IPO. It is not. If the real objective is to raise capital, migration may be a sensible first step, but the fundraise is a separate exercise with its own approvals, disclosures and costs. Plan them as two projects.

Voluntary migration versus the point where you have to move

The migration framework sits in Chapter IX of the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018, the same chapter that governs SME issues. Broadly, there are two situations.

Voluntary migration. A company listed on an SME exchange may choose to migrate to the main board if its shareholders approve it by special resolution through postal ballot, and if it meets the main board’s eligibility criteria. This is the route most companies take.

Migration triggered by capital size. The SME route is built for smaller issuers, and ICDR ties this to post-issue paid-up (face value) capital, not market capitalisation. At the time of writing, where a further issue of capital, such as a rights issue, preferential allotment or bonus issue, would take the paid-up capital of an SME-listed company above Rs 25 crore, the company has to migrate to the main board and list the new shares there, subject to meeting the main board’s eligibility criteria.

The practical trap here is the bonus issue. A generous bonus issue increases face value capital without a rupee of new money coming in, and it can push a company over the line by itself. If a bonus or a large preferential round is on your agenda, check where it leaves paid-up capital before the board approves it, not after.

Eligibility: the exchange sets the bar, and the bar moves

SEBI sets the framework; the detailed eligibility tests for migration are prescribed by each exchange through its own circulars. BSE and NSE have revised these criteria several times over the last few years, and they do not always match each other. I am deliberately not quoting the thresholds here, because any number I print today may be out of date by the time you read it. Pull the current migration circular from the exchange you are listed on before you do anything else.

What I can tell you is the shape of the test, because it has been consistent. Expect the exchange to look at some combination of:

Time on the SME platform. A minimum period of listing on the SME exchange before a migration application is entertained. Size. A minimum paid-up capital and a minimum market capitalisation, often measured as an average over a defined period rather than on a single day. Financial track record. Tests on revenue, operating profit or EBITDA, net profit and net worth across recent financial years. Shareholding. A minimum promoter holding and a minimum number of public shareholders, so that the main board is not inheriting a closely held stock. Clean record. No material regulatory action, no suspension of trading, no pending defaults to lenders or investors, and a clean compliance history with the exchange, often confirmed through certificates from the statutory auditor and a practising company secretary.

The last item is where applications most often stall. A late financial results filing, an unpaid listing fee or an unresolved investor complaint from two years ago will surface during the exchange’s review. Clean these up before you apply, not in response to the exchange’s query letter.

The process, step by step

The sequence below is the standard path. The exchange’s circular will list the exact documents and formats it wants, and those change from time to time.

1. Eligibility check against the current circular. Map every criterion to your audited numbers and shareholding data. If you are close to a threshold, especially a market capitalisation average, do not assume you will clear it; the exchange computes it its own way.

2. Board approval. The board approves the proposal to migrate, appoints a scrutiniser for the postal ballot, and approves the notice to shareholders.

3. Shareholder approval by postal ballot. This is the step that catches promoters off guard. ICDR requires a special resolution through postal ballot, and at the time of writing it adds a second test: the resolution can be acted upon only if the votes cast in favour by shareholders other than the promoters are at least two times the votes cast against by non-promoter shareholders. The promoters’ own block cannot carry the vote on its own. If your public shareholders are unhappy with the stock’s performance, this is where they will say so.

4. Application to the exchange. The company files the migration application with the supporting certificates, shareholding data, financial statements and the postal ballot results, along with the processing fee.

5. Exchange review and in-principle approval. The exchange scrutinises the application, raises queries and, once satisfied, grants approval. Expect at least one round of questions.

6. Final approval and the switch. The exchange notifies the date from which the shares will trade on the main board. From that date the stock moves off the SME segment, trading lot rules change, and the company’s obligations shift to the main board regime.

Timelines: plan in months, not weeks

There is no fixed statutory timeline for the whole exercise. The postal ballot alone involves a notice period and a voting window under the Companies Act rules, and exchange review time depends on the quality of the application and the exchange’s queue. In practice, from the first eligibility check to the first trade on the main board, you should plan in months. The biggest controllable delay is a messy compliance history that has to be explained or regularised during review.

One timing point worth thinking about: many of the financial tests are measured on audited annual numbers. If your latest audited year is the one that gets you over a threshold, the clock effectively starts when those accounts are adopted. Build the plan backwards from that.

What migration costs

The direct costs of migration are modest compared with an IPO, because there is no issue to manage. They typically include the exchange’s processing fee for the application, the main board annual listing fee (which is generally higher than on the SME platform and is linked to the company’s capital), depository and registrar charges, postal ballot and e-voting costs, and professional fees for the certificates, the application and any advisory support. Exchange fee schedules are published and revised periodically, so take the current figures from the exchange rather than from anyone’s memory, including mine.

The larger cost is the recurring one, and it is the one most boards underestimate: the cost of running a main board company every year after migration. That is the next section.

What changes after migration

Corporate governance under LODR. An entity whose shares are listed on an SME exchange enjoys a carve-out under Regulation 15 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015: several of the core corporate governance provisions do not apply to it. Once you migrate, that carve-out is gone. In practical terms that means the full LODR requirements on board composition and independent directors, the audit, nomination and remuneration and stakeholders’ relationship committees, the detailed related party transaction framework, and a corporate governance report in the annual report. Some of these, such as a minimum proportion of independent directors and an audit committee, already apply to a listed company under the Companies Act, 2013, so the jump is not from zero, but the LODR layer is materially heavier. SEBI has also been narrowing the gap between SME and main board obligations in recent amendments, so check where the line sits today.

Quarterly results. SME-listed companies file financial results half-yearly. On the main board, results are quarterly, with limited review by the statutory auditor. That is four closings a year instead of two, and it needs a finance function that can close books reliably and on time. If your month-end close is still a scramble, fix that first; my note on designing MIS for a growing company covers the reporting backbone you will need.

The market maker exits. Market-making is an SME-platform requirement: on an SME listing, the merchant banker has to arrange market-making in the scrip for three years from listing. The main board has no such mechanism. Once your shares move, liquidity comes only from genuine buyers and sellers. For a company with a thin, retail-heavy shareholder base, that can mean lower volumes and wider spreads, at least at first. If migration happens while the market-making period is still running, discuss the wind-down of the arrangement with your merchant banker in advance. For background on how that obligation works, see my piece on choosing an SME IPO merchant banker.

Trading lots. SME shares trade in large minimum lots. On the main board, shares trade in single units. That widens the pool of potential buyers, particularly small retail investors who could never write a cheque for an SME lot.

Visibility and investor base. Main board listing puts the stock in front of a wider set of investors and research desks. Some institutional investors are reluctant to hold SME counters because of lot sizes, liquidity and mandate restrictions; a main board listing removes some of those objections. It does not guarantee that anyone will actually buy.

When migration makes sense

In my view, migration is worth doing when most of these are true:

The company is clearly clearing the eligibility tests, not scraping past them. Revenue and profits are on a stable trajectory, so quarterly reporting will not expose volatility the market will punish. The finance and secretarial team can handle quarterly closes and a full governance calendar without heroics. The board already has, or can recruit, credible independent directors. And there is a concrete reason to be on the main board: a fundraise in the next year or two, an institutional investor who cannot hold an SME stock, or a paid-up capital increase that would force migration anyway.

When staying on the SME platform is the better call

Stay put, at least for now, if the main argument for migrating is "valuation will go up". Re-rating on migration is not a rule; it depends on the business, the float and the market at the time. Stay put if the compliance team is already stretched, if earnings are lumpy enough that quarterly results will create noise, or if the company only just meets the thresholds and a weak year could leave it struggling on the main board with no market maker behind the stock. There is no penalty for spending more time on the SME platform and arriving at the main board as a stronger company.

The same discipline that gets a company ready for its IPO applies here. Much of what I describe in pre-IPO structuring over 18 months (cleaning up related-party dealings, building the board, tightening the close) is exactly the groundwork a migration needs.

The concrete checklist

Before the board approves a migration proposal, I want every one of these answered in writing:

1. Current exchange circular pulled and every eligibility criterion mapped to audited numbers and shareholding data. 2. Paid-up capital headroom checked against any planned bonus, rights or preferential issue. 3. Compliance history reviewed: results filings, listing fees, investor complaints, any exchange or SEBI action. 4. Non-promoter shareholder sentiment assessed ahead of the postal ballot. 5. Board composition and committees gap-assessed against full LODR requirements. 6. Finance function tested on a quarterly close with limited review. 7. Market-maker arrangement and its wind-down discussed with the merchant banker. 8. One-time and recurring costs budgeted using current exchange fee schedules. 9. A clear, written reason why the company is better off on the main board than on the SME platform.

Bottom line

Migration from BSE SME or NSE Emerge to the main board is a regulatory step, not a fundraise and not a guaranteed re-rating. The exchange sets the eligibility bar through circulars that change, the non-promoter shareholders have a real say through the postal ballot, and the day after the switch the company carries full LODR governance, quarterly reporting and no market maker. For a company that has grown into the main board, that is a fair trade for wider access to investors and capital. For one that is only just eligible, a little more time on the SME platform is often the smarter move. The migration application is filed by the company and its company secretary, and the certificates are signed by its auditor and practising professionals; my job is to make sure the decision behind it is the right one.
