Regulation 30 of SEBI's LODR Regulations is India's material-events disclosure rule — the reason listed companies announce acquisitions, board changes, fraud, and regulatory actions to the exchanges. Schedule III lists events that are always material; the 2023 amendment added hard timelines, requiring disclosure within 30 minutes to 24 hours depending on the trigger.
| Rule | Regulation 30, SEBI (LODR) Regulations, 2015 |
|---|---|
| Deemed material | Schedule III Part A — M&A, fraud, defaults, regulatory action, key departures |
| Timelines (2023 amendment) | 30 min (board outcomes) · 12 h (events from within) · 24 h (others) |
| Materiality thresholds | Quantitative tests added in 2023 (e.g. 2% of turnover or net worth) |
| Where filings appear | NSE and BSE corporate announcements, then the company website |
What counts as a material event?
Regulation 30 is the rule that turns a corporate event into a public announcement. It requires a listed company to disclose any event or information that is material, and it answers the obvious next question, “material according to whom,” by splitting events into two schedules that leave very different amounts of room for judgment.
Some events are material by definition, listed in Schedule III Part A. Acquisitions and disposals, fraud or default, regulatory or enforcement action, the resignation of a managing director or auditor, winning or losing a major order: these must be disclosed whether or not the company thinks they matter. There is no judgment to exercise.
Everything else falls into Part B, the residual category where the company applies its own board-approved materiality policy. Here the 2023 amendment hardened the discretion with quantitative thresholds — an event whose value or impact exceeds 2% of turnover or net worth is treated as material, for instance — so that a plainly significant event can no longer be argued away. Designated officers are personally accountable for the call.
How fast must companies disclose?
Speed is the heart of the rule, and the 2023 amendment replaced the old “as soon as reasonably possible” with three hard deadlines. An outcome of a board meeting must be disclosed within 30 minutes of the meeting closing. An event that originates from within the company gets 12 hours. An event from outside — a court order, a regulator’s action — gets 24 hours.
The tiering tracks how much control the company has over timing. It knows the instant its own board decides something, so it gets 30 minutes. It learns of an external development with some lag, so it gets a day. The same 30-minute board-outcome deadline is what governs results and dividends, covered in board-meeting intimation vs outcome.
Regulation 30 vs the US 8-K
Anyone familiar with US filings will recognise the shape of Regulation 30 immediately: it is India’s answer to the 8-K. Both rest on the same philosophy: a defined list of material events, disclosed promptly to a public venue, so that no investor trades against a hidden development.
The difference is pace. The US 8-K generally allows four business days. Regulation 30 allows 12 to 24 hours for most events and 30 minutes for board outcomes. India runs a materially tighter clock, which is part of why disclosure latency on Indian exchanges is so low and why filings can move a stock within the same trading session.
What a Regulation 30 filing looks like
A Regulation 30 filing arrives as a dated, timestamped corporate announcement on the NSE and BSE, and then on the company’s own website. It names the event, gives the prescribed details, and where Schedule III requires it, explains the impact. The filings range from a one-line auditor resignation to a multi-page acquisition disclosure.
The practical problem is volume, not access. A large company files constantly, with routine, semi-routine, and genuinely market-moving items landing in the same stream, undifferentiated. Reading every filing is not feasible; the skill is filtering for materiality, which is exactly what a scoring layer is for. Our methodology documents how each filing is ranked.
Rumour verification
The 2023 round added a duty that did not exist before: rumour verification. The largest listed companies — phased in by market capitalisation, starting with the top 100 and extending to the top 250 — must confirm, deny, or clarify a market rumour reported in the mainstream media when it triggers a material price movement, within 24 hours.
The rule closes a long-standing gap. Before it, a company could let a price-moving rumour run, neither confirming nor denying, while insiders held an information edge. Now silence is not an option for the biggest names; they must speak to the rumour itself. Unscheduled Regulation 30 disclosures, rumour verifications included, run through our regulatory and compliance digests; the same disclosure discipline underlies the IPO documents explained in what a DRHP is.
Frequently asked questions
How is Regulation 30 different from the US 8-K?
Same philosophy — disclose material events promptly, against a defined list — but India's timelines are tighter: 12 to 24 hours for most events versus the 8-K's four business days, and 30 minutes for board-meeting outcomes.
Who decides whether an event is material?
Part A of Schedule III is deemed material — no judgment involved. For everything else the company applies its board-approved materiality policy, now anchored by quantitative thresholds, with designated officers personally responsible for the determination.
What changed in the 2023 amendment?
Three things: hard disclosure deadlines replaced 'as soon as reasonably possible', quantitative materiality thresholds replaced pure judgment, and large companies must verify or deny market rumours that move their stock.
Where can I read a company's Regulation 30 filings?
On the NSE and BSE corporate-announcement pages, free, timestamped on arrival. The volume is the problem — large companies file constantly, which is why analysts filter for materiality rather than reading everything.
Regulation 30 filings are unscheduled by definition. Gunpowder scores each one for materiality within minutes and alerts you to the ones that matter.
