In April 2025 the NSE quietly rewrote the rules for every company sitting on its Emerge platform. Overnight, a founder who listed an SME two years earlier at a ₹40 crore market cap discovered that the door to the main board now demanded ₹100 crore in revenue, ₹100 crore in average market capitalisation and a ₹75 crore net worth. An SME to mainboard migration that once looked like a formality became a two-year governance project. Miss one number and your shares stay parked on a platform where institutions rarely buy and liquidity thins out. This is the single biggest reason SME founders now call a Company Secretary a full year before they intend to move.
Governing provision: Regulation 277, SEBI (ICDR) Regulations, 2018 — migration needs a shareholder special resolution plus the exchange’s eligibility test.
Who must comply: Any company listed on NSE Emerge or BSE SME wanting to move to the main board.
The new bar: ≥ 3 years listed, revenue > ₹100 crore, average market cap ≥ ₹100 crore, positive EBITDA in 2 of 3 years, 500+ (NSE) or 1,000+ (BSE) public shareholders.
Key action: Run a migration eligibility gap analysis 12–18 months out and fix LODR and board gaps before you apply.
Time to act: Now — SEBI-revised BSE norms took effect 1 March 2026; NSE norms have applied since 1 May 2025.
The problem: the platform that was meant to be a stepping stone
India’s SME exchanges were built as a nursery. A company lists small, builds a public track record, and graduates to the main board where deeper pools of capital and index inclusion live. For years the graduation test was light. That era is over. Between the SME IPO boom of 2024 and a run of governance failures, SEBI and the exchanges tightened both the entry gate and the exit gate. The SME to mainboard migration route is now the exit gate that most founders underestimate.
The cost of getting it wrong is not a fine on day one — it is a company trapped. An SME script that cannot migrate keeps a lot size that most retail investors avoid, sits outside mainboard indices, and struggles to attract mutual funds and foreign portfolio investors who are barred or reluctant to hold SME paper. Valuation suffers. Follow-on fundraising suffers. And the promoter who assumed migration was automatic finds that the audit committee never met on time, the woman director was appointed late, or one quarter of LODR filings slipped — any of which can hold up an application. Regulation 277 of the SEBI (ICDR) Regulations, 2018 is the door; the exchange circulars are the lock.

What changed, and why the bar moved
The tightening came in two waves. First, the entry gate. Through the SEBI (ICDR) Second Amendment introduced in December 2024, a company can only file an SME IPO if it has posted operating profit (EBITDA) of at least ₹1 crore in two of the three preceding financial years. The same amendment capped the offer for sale at 20% of the issue size, stopped promoters selling more than 50% of their holding, doubled the minimum application size to ₹2 lakh, and limited “general corporate purposes” use of proceeds to 15% of the amount raised or ₹10 crore, whichever is lower.
Then the exit gate. In April 2025 the NSE issued Circular NSE/CML/67671, lifting the direct-migration bar to the numbers in the table above with effect from 1 May 2025. The BSE followed, and SEBI-approved revisions to the BSE framework took effect on 1 March 2026, adding the ₹15 crore average EBITDA test and the 1,000-shareholder floor. SEBI’s own ICDR amendment of 4 March 2025 raised the disclosure and governance standard for SME-listed entities across the board, deliberately narrowing the gap between an SME company and a mainboard one so that migration is a step, not a leap.
The market backdrop explains the mood. SME issuance came roaring back after a lull — 68 SMEs raised ₹3,131 crore from June 2025 — and the regulator wants only genuinely scaled, well-governed companies crossing to the main board. Regulation 277 of the ICDR Regulations sets the legal frame: an SME issuer whose post-issue paid-up capital exceeds the SME threshold may migrate, subject to a special resolution passed by shareholders and to the receiving exchange’s eligibility criteria. Two ingredients, both non-negotiable: the numbers and the shareholder mandate.
What you must do now: a migration readiness plan
Migration is won or lost in the two years before you file, because the criteria look backwards at your revenue, profit and compliance record. Here is the sequence a Company Secretary works through with an SME-listed board.
Step 1 — Confirm the three-year clock and the LODR record
Check the date of your SME listing. You need at least three completed years on the platform, and, just as important, three years of clean compliance with the SEBI (LODR) Regulations, 2015. Pull every quarterly filing, financial result, corporate governance report and shareholding pattern. A single missed or delayed submission — Regulation 33 results, Regulation 27(2) governance reports, Regulation 31 shareholding — is a pending non-compliance that stalls the application.
Step 2 — Run the financial eligibility test against audited numbers
Map your last three audited financial statements to the exchange test: revenue above ₹100 crore in the latest year, positive EBITDA in the required years, and net worth at or above ₹75 crore for NSE. If a number falls short, you have a planning problem, not a paperwork problem — decide whether to wait a year for the figures to catch up.
Step 3 — Fix the shareholder count and promoter holding
Verify you have 500 public shareholders (NSE) or 1,000 (BSE) on the intended application date, and that promoter holding has not dropped below 50% of what promoters held at SME listing. Both are shareholding-structure questions your registrar and transfer agent can confirm from the benpos data.
Step 4 — Close the mainboard governance gaps
The main board applies the full LODR to you from day one. Confirm your board composition meets Regulation 17, that the audit committee (Regulation 18) and the nomination and remuneration committee (Regulation 19) are correctly constituted and have met on schedule, and that a whole-time Company Secretary, CFO and MD/CEO are appointed under Section 203 of the Companies Act, 2013. These are the items with the longest cure time.
Step 5 — Pass the special resolution and prepare the application
Under Regulation 277, migration requires shareholder approval by special resolution. Convene the general meeting, pass the resolution, and file the postal ballot or e-voting results. Then assemble the migration application: the exchange’s prescribed form, board and shareholder resolutions, three years of audited accounts, the compliance track record, a certificate from a practising Company Secretary or Chartered Accountant confirming eligibility, and the “no disqualification” declarations.
Step 6 — Clear the disqualification checklist
The exchange will confirm the company and its promoters are not debarred by SEBI, not classified as wilful defaulters or fraudulent borrowers, not fugitive economic offenders, not under IBC insolvency or winding-up proceedings, and that the scrip has not been suspended for non-compliance in the last 12 months. Any one of these blocks the move.
The deeper implication
According to CS Sapna Malpani, the raised bar is doing exactly what SEBI intended: it is turning the SME platform back into a proving ground rather than a shortcut. The companies that migrate cleanly in 2026 and 2027 are the ones that treated LODR compliance as a discipline from their first day of SME listing, not a chore to fix at the finish line. The ones that stumble are those that saw the SME board as a lighter regime and let governance drift.
The forward view: expect the entry and exit gates to keep converging. SEBI’s March 2025 ICDR amendment already pushed mainboard-style disclosure onto SME issuers. The realistic planning assumption for any founder listing on Emerge or BSE SME today is that by the time they qualify to migrate, the SME regime will look almost identical to the main board. Build to mainboard governance from the start, and migration becomes an administrative event instead of a scramble. That is the cheapest insurance a growing company can buy.
Comparison with related routes founders confuse
Three separate paths get muddled in board conversations, and picking the wrong one wastes months.
Direct migration under Regulation 277 is for a company already listed on the SME platform for three years that meets the exchange’s mainboard eligibility numbers. It needs a special resolution and an exchange application — no fresh public issue.
A fresh mainboard IPO is the alternative when you do not want to wait three years or cannot meet the direct-migration numbers yet; you run a full SEBI (ICDR) mainboard public issue with a merchant banker and a DRHP. An SME IPO is the entry event itself, governed by the SME chapter of the ICDR Regulations and now carrying the ₹1 crore EBITDA and ₹2 lakh application-size conditions. Migration is not a re-IPO; it is a change of listing segment. Confusing it with a fresh issue is the most common and most expensive planning error.

Frequently asked questions
What is SME to mainboard migration in India?
SME to mainboard migration is the process by which a company already listed on an SME exchange platform — NSE Emerge or BSE SME — moves its listing to the main board of the same exchange. It is governed by Regulation 277 of the SEBI (ICDR) Regulations, 2018, and requires both a shareholder special resolution and satisfaction of the receiving exchange’s eligibility criteria. It is not a fresh public issue; the company changes listing segment without issuing new shares to the public, provided it has completed at least three years on the SME platform with a clean compliance record.
What are the eligibility criteria for SME to mainboard migration in 2026?
Under the current NSE and BSE frameworks, a company needs at least three years on the SME platform, paid-up equity capital of ₹10 crore or more, average market capitalisation of at least ₹100 crore, revenue from operations above ₹100 crore in the latest financial year, and positive profitability (NSE looks for positive EBITDA in two of three years; BSE for average EBITDA of ₹15 crore over three years). NSE also requires net worth of ₹75 crore and 500 public shareholders, while BSE requires 1,000 public shareholders. The company and its promoters must carry no SEBI debarment, wilful-defaulter tag or insolvency proceedings.
When did the new SME migration rules take effect?
The NSE tightened its direct-migration criteria through Circular NSE/CML/67671 dated 24 April 2025, effective 1 May 2025. The BSE framework was revised in line with SEBI-approved norms that took effect on 1 March 2026, adding the average EBITDA and 1,000-shareholder tests. Separately, SME IPO entry conditions changed under the SEBI (ICDR) Second Amendment of December 2024, which is why both the entry gate and the exit gate now look far stricter than they did two years ago.
Does SME to mainboard migration need shareholder approval?
Yes. Regulation 277 of the SEBI (ICDR) Regulations, 2018 requires the company to pass a special resolution — a 75% majority of votes cast — approving the migration before it applies to the exchange. Practically, the board first approves the proposal, then the company convenes a general meeting or runs a postal ballot or e-voting, files the results, and only then submits the migration application together with audited accounts, the compliance record and an eligibility certificate from a practising professional.
What happens to LODR compliance after migration?
On migration, the full SEBI (LODR) Regulations, 2015 applicable to mainboard companies apply from day one — quarterly financial results under Regulation 33, the board composition and independent director requirements of Regulation 17, audit committee obligations under Regulation 18, and continuous disclosure of material events. A company that treated SME-stage LODR lightly will feel the jump. This is why a Company Secretary builds mainboard governance well before the migration application, so the transition is administrative rather than a scramble to constitute committees and appoint key managerial personnel at the last minute.
Why should an SME company migrate to the main board at all?
The main board opens access to capital the SME platform restricts. Mutual funds and foreign portfolio investors participate more freely, lot sizes shrink to retail-friendly levels, index inclusion becomes possible, and follow-on fundraising and valuations generally improve. Staying on the SME platform after a company has scaled can cap liquidity and depress the share price relative to peers on the main board. For a company that meets the ₹100 crore thresholds, migration is usually the logical next step in its capital-markets journey — provided the governance and compliance record supports it.
