Migration From SME to Mainboard
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.
What Is SME-to-Mainboard Migration?
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:
- SME Platform (BSE SME / NSE Emerge): Designed for small and medium enterprises with lower eligibility thresholds, lighter compliance requirements, and a mandatory market-making mechanism to ensure liquidity.
- Mainboard (BSE / NSE): The primary exchange for larger, established companies with significantly higher financial, governance, and disclosure standards.
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.
Regulatory Framework Governing Migration
Migration is governed by a multi-layered regulatory framework, which includes:
SEBI Regulations
- SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018 (ICDR Regulations): Chapter XB governs the framework for SME platforms and migration to the mainboard.
- SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015 (LODR Regulations): Once the migration process is complete, the company must comply with the full LODR requirements applicable to mainboard-listed companies, including quarterly reporting, board composition, and continuous disclosure obligations.
- SEBI Circular dated May 18, 2010: The foundational circular that established the initial migration policy; subsequent exchange-specific updates build upon this framework.
Exchange-Specific Circulars
Both BSE and NSE have issued their own updated eligibility circulars:
- NSE Circular NSE/CML/67671 dated April 24, 2025 (effective May 1, 2025) - comprehensively revised NSE SME migration eligibility criteria.
- BSE August 2025 Circular - significantly raised BSE SME migration thresholds, particularly on EBITDA and shareholder count.
- SEBI-revised BSE norms effective March 1, 2026 - the latest round of tightening for BSE SME migration.
Voluntary vs. Mandatory Migration
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 | Must migrate or comply with full LODR |
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.
Migration Criteria From BSE SME to BSE Mainboard
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:
Financial Criteria
- Paid-up capital: Minimum ₹10 crore
- Market capitalisation: Minimum average market capitalisation of ₹100 crore for the last 6 months (total of all trading days' market capitalisation ÷ number of trading days) - higher from the previous ₹25 crore requirement
- Operating profit (EBITDA): Average EBITDA of ₹15 crore over the last 3 financial years, with a minimum of ₹10 crore in each individual year - significantly tightened from the earlier requirement of simply positive EBITDA in 2 of 3 years
- Net tangible assets: Minimum ₹3 crore in each of the last 3 financial years
- PAT: Positive profit after tax in the most recent financial year
Listing Track Record
- Minimum 3 years of listing on the BSE SME platform (effective January 2024, raised from 2 years)

The Migration Process: Step by Step
The typical SME-to-mainboard migration timeline is 3.5 to 6 months, depending on company readiness and exchange approval timelines.
Step 1: Internal Eligibility Assessment
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.
Step 2: Shareholder Approval via Special Resolution
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).
Step 3: Appointment of Intermediaries
The company typically appoints:
- A SEBI-registered Merchant Banker to manage the process and due diligence
- A Compliance Officer / Company Secretary to coordinate regulatory filings
- A SEBI-registered Credit Rating Agency (for IPO proceeds certification)
- A Registrar and Transfer Agent (RTA)
Step 4: Document Preparation
This is the most intensive phase. Required documents include:
- Audited financial statements for the last 3 years
- Shareholding pattern (latest quarter)
- Board resolution and special resolution passed by shareholders
- Certificate from a credit rating agency on IPO proceeds utilisation
- Compliance certificate from a practising company secretary
- No-objection certificate (if applicable) from the existing stock exchange
- Disclosure of all pending litigation, regulatory actions, and SCORES status
- PAN and DIN of all directors
- Details of any change in control or name change in the last year
Step 5: Application to the Exchange
The company applies for a migration to the mainboard exchange (BSE or NSE) with all necessary documents and fees.
Step 6: Exchange Review and Due Diligence
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.
Step 7: In-Principle Approval
Once satisfied, the exchange issues an in-principle approval for migration.
Step 8: Compliance Transition
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.
Step 9: Delisting from SME + Listing on Mainboard
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.
Important Post-Migration Compliance Obligations
Once the company is listed on the mainboard, it shifts to the LODR framework from the relatively lighter SME framework. The major changes include:
- Board composition: Must include independent directors for meeting LODR requirements
- Audit committee, Nomination & Remuneration Committee (NRC): Mandatory under LODR
- Quarterly financial results: Must be published as per LODR timelines
- Related-party transactions: Full LODR disclosure and shareholder approval requirements apply
- Corporate governance report: Must be submitted with the annual report
- SCORES compliance: Must maintain an active grievance redressal mechanism
- Market making is no longer required: But the stock must have natural liquidity
- Minimum public shareholding (MPS) of 25%: Must be maintained under SEBI norms
- Minimum investment lot restriction: The restriction that existed on the SME platform (minimum ₹1 lakh application) is lifted - retail investors can buy even a single share
Why Companies Migrate from SME to Mainboard: The Benefits
Graduating to the Mainboard opens up a new paradigm of growth, capital access, and brand reputation for a company:
Access to a Larger and More Diverse Investor Base
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.
Enhanced Market Capitalisation and Liquidity
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.
Brand Credibility and Visibility
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.
Easier Capital Raising
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.
Talent Attraction
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.
Migration Statistics: A Market in Transition
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).
What Are The Challenges in Migration for SMEs
Stricter Financial Bars
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.
Market Cap Volatility
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.
Promoter Lock-In and Exit Restrictions
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.
SCORES Compliance
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.
Surveillance Category Overhang
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.
Operational and Governance Transition
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.
The 2025–2026 Regulatory Reset: What Changed
SEBI and the exchanges have fundamentally redefined what SME-to-mainboard migration means:
- January 2024: Minimum listing tenure raised from 2 to 3 years.
- March 2024: NSE reduced the minimum public shareholders from 1,000 to 500.
- May 2025: NSE overhauled its entire migration criteria with Circular NSE/CML/67671 - adding revenue threshold (>₹100 crore), higher net worth (₹75 crore), and tighter promoter conditions.
- August 2025: BSE raised the market cap bar to ₹100 crore, EBITDA to ₹15 crore average, and public shareholder count to 1,000.
- March 2026: SEBI further revised BSE SME migration norms.
Mainboard Migration Benefit For Investors: What Migration Means for Your Holdings
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:
- Lot size restriction removed: Shares can now be bought or sold in any quantity, which often increases trading volumes.
- Wider institutional participation: FPIs and mutual funds can now invest, which typically supports price discovery.
- Valuation re-rating: Companies often see a re-rating in valuation multiples post-migration as liquidity and investor base improve.
- Higher compliance scrutiny: Increased reporting requirements mean greater transparency, which benefits long-term investors.
- No market maker: The market-making mechanism that guaranteed liquidity on the SME platform ends; the stock now relies entirely on natural demand and supply.
Conclusion
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.
