Minimum Public Shareholding (MPS)
Minimum Public Shareholding (MPS) is the SEBI-mandated requirement that all listed companies in India must maintain at least 25% of their total shareholding with public (non-promoter) shareholders, ensuring a minimum level of dispersed ownership and market liquidity.
The MPS norm was introduced by SEBI pursuant to amendments to the Securities Contracts (Regulation) Rules, 1957. The 25% minimum public float requirement applies to all companies listed on Indian stock exchanges. For certain government-owned companies (public sector undertakings or PSUs), a lower threshold of 10% was permitted under specific transitional provisions, with a roadmap to eventually achieve 25%.
The rationale for the MPS requirement is rooted in market quality. A company where promoters hold, say, 90% of the shares has only 10% in public hands. This thin float creates illiquidity, allows prices to be more easily influenced by small orders, and limits the ability of institutional investors to build or exit meaningful positions without causing large price movements. SEBI determined that 25% public float is the minimum necessary for a reasonably liquid and discoverable market.
Companies that fall below the 25% MPS threshold—typically because promoters have increased their shareholding through creeping acquisition or the company failed to dilute sufficiently at IPO—are required to achieve compliance within a specified timeframe through one or more of the following routes: an Offer for Sale (OFS) by promoters, a follow-on public offer (FPO), a Qualified Institutional Placement (QIP), or issuance of bonus shares or rights shares to public shareholders. Non-compliance attracts penalties from SEBI including freezing of promoter voting rights above the permitted threshold and trading restrictions.
SEBI publishes lists of companies not meeting MPS norms and monitors compliance closely. For investors, a company trading below the MPS threshold may be subject to dilutive equity issuances in the future—specifically OFS transactions by promoters—which can temporarily create selling pressure on the stock. Monitoring the promoter shareholding percentage relative to the 75% cap is thus a useful tool for anticipating potential supply-side events in a stock.
