A Complete Guide to Migration in India's Capital Markets. Learn how small and medium enterprises transition to the primary national stock exchanges.
Imagine a company that was small in size and raised a small amount of capital from a few investors through its SME IPO on the BSE SME or the NSE Emerge. The same company now has an opportunity to move to the biggest exchanges in the country. This is the story of small companies of India migrating to the mainboard exchanges. The journey from SME to the Mainboard of stock exchanges means a lot for these smaller companies - it is a public declaration of scale, governance and permanence. It is a clear signal that the company has successfully developed to the point where it is ready to compete with leading companies being traded on national stock exchanges.
This article provides a comprehensive overview of everything you need to know about the SME-to-Mainboard migration route, covering the regulatory framework, migration requirements, procedures, documentation, challenges and the latest trends shaping this pathway as of 2026.
Migration, in the capital markets context, refers to the formal shift of a company listed on the SME platform of BSE (BSE SME) or NSE (NSE Emerge) to the mainboard of the respective exchange - BSE or NSE.
India has two distinct listing ecosystems for equity:
The SME platform was always conceived as a launchpad, not a permanent home. SEBI and the exchanges designed it with migration as the intended end-state for successful companies - a structured graduation pathway.
Migration is governed by a multi-layered regulatory framework, which includes:
Both BSE and NSE have issued their own updated eligibility circulars:
SEBI has clearly defined the migration triggers based on paid-up capital:
| Paid-Up Capital Range | Migration Status |
|---|---|
| Less than ₹10 crore | Must remain on the SME platform |
| Between ₹10 crore and ₹25 crore | Voluntary migration permitted |
| Exceeding ₹25 crore | Totally depends on the company's choice |
Important 2025 update: With the latest changes to the SEBI ICDR, SMEs with paid-up capital exceeding ₹25 crore are eligible to raise additional funding without migrating to the mainboard exchange, provided they comply with the SEBI LODR Regulations, 2015.
The most updated BSE migration norms (effective August 2025, with further SEBI revisions from March 2026) are substantially tighter than what existed even two years ago. The key eligibility conditions are:
If the company has changed its name in the last 1 year, it must demonstrate revenue of at least ₹1 crore in each of the preceding 3 financial years (restated and consolidated) from the activity suggested by the new name.
NSE issued its revised migration criteria vide Circular NSE/CML/67671, effective May 1, 2025.
| Parameter | BSE SME → BSE Mainboard | NSE Emerge → NSE Mainboard |
|---|---|---|
| Min. Paid-up Capital | ₹10 crore | ₹10 crore |
| Min. Market Cap | ₹100 crore (6-month average) | ₹100 crore (3-month average) |
| Revenue Threshold | Not explicitly specified | >₹100 crore in the last FY |
| EBITDA Requirement | Avg. ₹15 crore (3 years); min ₹10 crore/year | Positive in 2 of 3 financial years |
| Net Worth | Not separately stated | ₹75 crore |
| Public Shareholders | 1,000 | 500 |
| Listing Period | 3 years | 3 years |
| Promoter Holding | Min. 20% | Min. 20%; ≥50% of listing-day holding |
| Liquidity | 5% traded; 80% trading days | Not explicitly quantified |
| SCORES Complaints | Nil | Nil |
| IPO Proceeds Certification | Required (credit rating agency) | Required |
The typical SME-to-mainboard migration timeline is 3.5 to 6 months, depending on company readiness and exchange approval timelines.
The company does a comprehensive self-assessment in coordination with its merchant banker or compliance advisor against the relevant exchange's checklist in relation to its financials, shareholding pattern, market capitalisation, governance track record and SCORES status.
A special resolution must be passed at least two-thirds of non-promoter shareholders (public shareholders) must vote in favour of the migration. This is typically done at an Annual General Meeting (AGM) or an Extraordinary General Meeting (EGM).
The company typically appoints:
This is the most intensive phase. Required documents include:
The company applies for a migration to the mainboard exchange (BSE or NSE) with all necessary documents and fees.
The exchange conducts its due diligence by reviewing the financials, compliance report and governance documentation. It can ask for further clarification if needed. Both the NSE and BSE have the right to refuse migration applications for any reason if anything is found inappropriate.
Once satisfied, the exchange issues an in-principle approval for migration.
The company moves from the SME-specific compliance to LODR Regulations of SEBI, 2015, which includes a change in board structure (independent directors, audit committee), quarterly financials and continuous disclosure obligations.
The company gets delisted from the SME platform and listed on the mainboard simultaneously. The market-making arrangement, which is mandatory on SME platforms, is discontinued.
Once the company is listed on the mainboard, it shifts to the LODR framework from the relatively lighter SME framework. The major changes include:
Graduating to the Mainboard opens up a new paradigm of growth, capital access and brand reputation for a company:
The mainboard opens the company to institutional investors - domestic mutual funds, foreign portfolio investors (FPIs), insurance companies and pension funds that are restricted from investing in SME-listed companies due to internal mandates.
When more players participate without any restrictions on minimum lot size, it leads to improved liquidity. Improved liquidity usually leads to stable and even better valuations.
A listing on the NSE/BSE mainboard brings in a different brand perception compared to an SME listing. For B2B firms and their large enterprise clients, a mainboard listing works as an essential means to convey a message of financial stability and institutional credibility.
On the mainboard, companies can raise follow-on capital through Qualified Institutional Placements (QIPs), rights issues and Offer for Sale (OFS) mechanisms - all at significantly lower cost and with a much wider pool of potential investors.
ESOPs from a mainboard-listed company are far more attractive to senior talent than those from an SME-listed entity, both in terms of liquidity and perceived market value.
The migration pipeline tells a fascinating story of regulatory evolution:
| Year | No. of Migrations |
|---|---|
| 2020–2022 (avg.) | ~50 per year |
| 2022 | 62 |
| 2023 | 38 |
| 2024 | 12–14 |
| 2025 | 3 |
| June 2025–May 2026 | 23 |
Between 2015 and 2025, of approximately 1,420 companies listed on BSE SME and NSE Emerge, only 336, about 24%, eventually migrated to the mainboard. As of early 2026, around 199 companies from the BSE SME and 158 from the NSE Emerge have migrated, for a total of approximately 360.
The sharp decline observed between 2024 and 2025 comes directly after changes to the norms, specifically the increase in the minimum listing requirement from 2 to 3 years (January 2024), the increase in the market capitalisation requirement from ₹25 crore to ₹100 crore and the significant increase in the number of public shareholders.
However, migration numbers are recovering: 23 companies migrated in the 12 months ending May 2026, compared to just 13 the year before, suggesting the first cohort of companies that listed in 2021–2022 under the new norms is now beginning to qualify.
Sector-wise, textile companies have led all migrations at 44 companies, followed by machinery and equipment (33) and food and tobacco (29).
The combination of higher EBITDA floors, revenue thresholds and net worth requirements means that many SMEs that were once migration-eligible under older norms no longer qualify today.
The 6-month average market cap requirement (BSE) and 3-month average (NSE) means that even a financially eligible company could fail to migrate purely due to a period of stock price weakness.
NSE now requires promoters to hold at least 50% of their listing-day shareholding at the time of migration, penalising promoters who have sold down their stakes aggressively post-listing.
Even a single unresolved investor complaint on SEBI SCORES can block migration. Companies with a history of poor investor communication are often caught off guard by this condition.
If a stock has been placed under enhanced surveillance or trade-to-trade categories, a mandatory 2-month cooling period must be observed even after the surveillance is lifted, before migration can be applied for.
Migrating from SME compliance to full LODR compliance requires a meaningful upgrade in board governance, internal controls and financial reporting infrastructure and this takes time and incurs costs.
SEBI and the exchanges have fundamentally redefined what SME-to-mainboard migration means:
When an SME-listed company migrates to the mainboard, existing shareholders automatically hold mainboard shares - no action is required. However, there are several practical implications:
The SME-to-mainboard migration pathway is India's structured mechanism for recognising corporate growth and rewarding it with access to deeper capital. But as the regulatory architecture has matured significantly since 2024, migration is no longer an automatic entitlement - it is a competitive milestone.
The lessons are clear for promoters: migration requires consistent financial performance in several years, clean corporate governance, diversified public shareholding and active communication with investors. For investors, a company that is preparing itself for or undergoing migration is a strong indicator of readiness and confidence in growth on the part of management.
Given that there are already 23 migrations from June 2025 to May 2026 and with a sizeable number of 2021-2022 SME listings now coming up to their three-year periods of eligibility, migration will undoubtedly become more common, but only for those companies that have built the financial and governance foundations the new rules demand.
