Disclosure of Material Information During Trading Hours

Few obligations under the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015 are as unforgiving of delay as Regulation 30. A material development — a merger approved by the board, a large order won, a regulatory penalty imposed — is worth nothing to the market if it reaches investors hours or days late, by which time informed insiders may already have traded on it. The 2023 and 2024 amendments turned what was once a loose “as soon as possible” standard into a hard stopwatch: thirty minutes for board decisions, twelve hours for events emanating from within the entity, and twenty-four hours for everything else, with a special rule for meetings that close after trading hours. This chapter unpacks how that clock works, what “trading hours” means in practice, when the clock actually starts, and how SEBI and the Securities Appellate Tribunal have enforced it — culminating in the Reliance–Facebook–Jio penalty upheld by the Supreme Court in December 2025.

Why Timing Is the Essence of Disclosure

The disclosure regime under Regulation 30 rests on a single economic premise: a securities market is fair only when all investors have access to the same price-relevant information at the same time. Delay is not a neutral inconvenience — it is the very window during which selective trading, leakage and manipulation occur. This is why the legislature shifted, over successive amendments, from a vague obligation to disclose material events “as soon as possible” to a precisely quantified set of deadlines under Regulation 30(6).

The premise is the same one that animates the parallel insider-trading framework. As the Appellate Authority recognised in Hindustan Lever Ltd v SEBI (1998) 18 SCL 311, information about a corporate development — there, the proposed merger of HLL with Brooke Bond Lipton India Ltd — is “price sensitive” the moment it can move the security, and the law’s concern is to neutralise the information advantage of those who learn of it first. Regulation 30 attacks that advantage from the disclosure side: by compressing the time between a material event and its public dissemination to minutes or hours, it leaves little room for the asymmetry to be exploited. For the foundational vocabulary — what counts as a “listed entity”, “material” and “event or information” — see Introduction, Scope and Definitions.

The Anatomy of Regulation 30

Regulation 30 is best understood as a layered structure. Regulation 30(1) imposes the continuing duty to disclose to the stock exchange(s) all events or information that are material. Regulation 30(2) and (3), read with Schedule III, Part A, then divide material developments into two classes. Events listed in Paragraph A of Part A — such as acquisitions, schemes of arrangement, change in directors or auditors, and outcomes of board meetings — are deemed material and must be disclosed without any further materiality assessment. Events in Paragraph B — such as commencement or postponement of commercial production, awards of orders, or litigation — are disclosable only if they cross the materiality threshold the entity has fixed under its policy.

Regulation 30(4)(i) supplies the materiality test itself, and Regulation 30(6) supplies the timelines. Regulation 30(8) requires the disclosures to be hosted on the entity’s website (for a minimum period, currently five years) so the record is not lost once the stock-exchange filing scrolls off the feed. Regulation 30(9), (10) and (11) add specialised duties — disclosure of agreements binding the entity, a designated materiality policy and key managerial personnel authorised to determine materiality, and the verification of market rumours. These obligations form one limb of the broader common obligations of listed entities and are governed by the overarching principles governing disclosures in Regulation 4.

The Materiality Test under Regulation 30(4)

Before timing can matter, the entity must decide whether the event is material at all. Regulation 30(4)(i) sets out a hybrid test. Information is material if (a) its omission is likely to result in discontinuity or alteration of an event or information already publicly available; or (b) its omission is likely to result in significant market reaction if it later comes to light; or (c) in the opinion of the board it is otherwise material.

The 2023 Second Amendment, effective 14 July 2023, added a fourth, quantitative limb to bring uniformity to entities’ materiality policies. An event is also material where its value or expected impact exceeds the lower of: two per cent of turnover; two per cent of net worth (except where net worth is negative); or five per cent of the average of the absolute value of profit or loss after tax, in each case on the basis of the most recent audited consolidated financial statements. The deliberate choice of the lower figure, and of the absolute three-year average for the profit limb, was designed to prevent loss-making or low-net-worth entities from setting an artificially high bar that would suppress disclosures. The interaction of these tests with board-level governance is examined further in Audit Committee and Board of Directors Composition.

The Thirty-Minute Rule for Board Decisions

The most demanding deadline in the regime applies to decisions taken at meetings of the board of directors. Under Regulation 30(6), where a material event or information arises from a decision taken in a board meeting, the entity must disclose it to the stock exchange(s) within thirty minutes of the closure of that meeting. The rationale is obvious: board outcomes — dividends, fund-raising, mergers, results — are precisely the developments most likely to move price, and a board meeting concentrates that knowledge in a small group at a known moment in time.

The thirty-minute clock runs from the formal closure of the meeting, not from when minutes are signed or a press release is polished. In practice this requires the compliance function to have draft intimations prepared in advance for each likely outcome, so that the disclosure can be filed the instant the chair declares the meeting closed. A board that approves a fund-raising at 2:40 p.m. cannot wait until the market closes to inform the exchange; the disclosure must reach the exchange by 3:10 p.m., during the very trading session in which the price would otherwise react to leaked or guessed information.

What “Trading Hours” Means and the Three-Hour Carve-Out

The thirty-minute rule assumes a meeting that closes while it can still be acted upon the same session. But boards routinely meet into the evening. Regulation 30(6) therefore carries a proviso for meetings that conclude after trading hours: where the board meeting closes after the close of trading but more than three hours before the beginning of the next trading session, disclosure must be made within three hours of the closure of the meeting. The object is to ensure that material outcomes are in the public domain well before the market reopens, so that no trader can act on the result before the broader market has digested it.

“Trading hours” for this purpose are the normal market hours of the recognised stock exchange (on the NSE and BSE equity segment, 9:15 a.m. to 3:30 p.m.). A board that finishes at 6:00 p.m. — well over three hours before the 9:15 a.m. open — must disclose by 9:00 p.m. that night. A board that finishes at, say, 8:00 a.m. on a trading day, within thirty minutes of the open, falls back on the ordinary thirty-minute window. The architecture is designed so that, in every permutation, the market is informed before it can trade on the development, never after.

The Twelve-Hour and Twenty-Four-Hour Windows

Not every material development emerges from a board meeting. Regulation 30(6) accordingly fixes two further windows. Where the event or information emanates from within the listed entity — for example, a decision of management below board level, the winning of a large contract, or a default — disclosure must be made within twelve hours of the occurrence of the event. Where the event or information does not emanate from within the entity — typically an order, notice or decision of a court, tribunal or regulator received from outside — the window is twenty-four hours.

The distinction reflects a simple practical judgment about how quickly the entity can reasonably be expected to know and verify the development. Information generated inside the company is, in principle, immediately available to it; information arriving from outside may require time to authenticate and to assess against the materiality thresholds. The longer external window is not a licence to sit on bad news — it is a recognition that, for instance, a complex regulatory order may need a prima facie reading before the entity can responsibly characterise it to the market.

When Does the Clock Actually Start?

The hardest question in practice is identifying the precise moment the timeline begins. The Industry Standards Note on Regulation 30 — framed by the Industry Standards Forum and made mandatory by SEBI’s circular of 21 May 2024 (operative from 1 December 2024) — clarifies that the clock under Regulation 30(6) begins only when an officer of the entity, within the meaning of the Companies Act, 2013, first becomes aware of the event through a credible source. A rumour in a chat group is not a credible source; a signed order, a counterparty communication or an internal management decision is.

The Note also identifies circumstances that may justify a reasonable delay without attracting penalty: force majeure events, the time genuinely required to complete a prima facie assessment of materiality (for example, of an order, fraud, claim or action), and situations where the information concerns another person and the entity is not itself involved. These are calibrated defences, not open-ended excuses; the burden remains on the entity to show that its delay was reasonable and bona fide. The Note must be read alongside the entity-level disclosure duties surveyed in Specific Listing Obligations (Equity).

Rumour Verification: Regulation 30(11) and the Trading-Hours Problem

The disclosure clock is not the only time-sensitive obligation that bites during trading hours. Regulation 30(11) requires the largest listed entities to verify market rumours. As originally framed, the duty was triggered by rumours “reported in the mainstream media.” The 2024 amendment shifted the trigger to the happening of a material price movement in the entity’s securities, applicable to the top 100 listed entities by market capitalisation from 1 June 2024 and the top 250 from 1 December 2024.

The entity must confirm, deny or clarify the rumour as soon as reasonably possible and not later than twenty-four hours from the trigger of the material price movement. Crucially, where the rumour concerns a transaction with SEBI-specified pricing norms, the amendment allows the unaffected price to be used — stripping out the rumour-driven spike — provided the rumour is confirmed within twenty-four hours of the price movement. This gives entities a strong incentive to respond within the trading-hours window rather than let a rumour inflate the reference price.

The Reliance–Facebook–Jio Disclosure Case

The most consequential recent enforcement on timing is the Reliance–Facebook–Jio matter. In late March 2020, mainstream media reported on 24 and 25 March that Facebook was negotiating a large investment in Jio Platforms. Reliance Industries Ltd did not confirm, deny or clarify; it intimated the stock exchanges only on 22 April 2020, when the USD investment (for a 9.99% stake) was formally announced — a gap of some twenty-eight days during which the market traded amid speculation. SEBI’s adjudicating officer, by order of June 2022, imposed a combined penalty of Rs 30 lakh on RIL and its compliance officers, holding that the failure to respond promptly to the selectively public information violated the fair-disclosure principle in Principle 4 of Schedule A to the SEBI (Prohibition of Insider Trading) Regulations, 2015.

On 2 May 2025 the Securities Appellate Tribunal dismissed RIL’s appeal, holding that the deal had reached a credible and concrete stage well before the formal announcement and that media reports did not absolve the entity of its duty to authenticate the information for the market. In December 2025 the Supreme Court declined to interfere, treating the question as essentially one of fact and upholding the penalty. The case is a sharp reminder that even India’s largest issuer cannot let material information sit unconfirmed while the market trades on rumour — the very mischief Regulation 30(6) and 30(11) exist to prevent.

Media Reports and “Generally Available” Information

RIL’s defence — that the deal was already in the press — raises a recurring tension. Does extensive media coverage make information “generally available”, so that the entity need not disclose it? The Securities Appellate Tribunal addressed the cognate question in the Future Retail matter, FCRPL v SEBI (SAT, 2024), where it held that detailed, specific media coverage of a proposed demerger could constitute generally available information, and that a company’s bald clarification of “no final decision” did not negate that availability.

That reasoning, however, cuts both ways. The earlier Appellate Authority view in Hindustan Lever Ltd v SEBI (1998) 18 SCL 311 had likewise accepted that widely published merger news could lose its “unpublished” character. But the RIL outcome shows that media speculation is not a safe harbour for a listed entity’s own disclosure duty: the obligation under Regulation 30(11) is precisely to verify — to confirm or deny — what the media reports, not to shelter behind it. The two strands are reconciled by recognising that the insider-trading analysis (is the information still UPSI for trading purposes?) is distinct from the LODR analysis (has the entity discharged its affirmative duty to inform the exchange?).

Consequences of Delayed or Non-Disclosure

A breach of Regulation 30 — whether non-disclosure or delayed disclosure — exposes the entity to a graduated set of consequences. Stock exchanges levy standardised fines under SEBI’s circular on standard operating procedures for non-compliance with continuous disclosure requirements. Beyond exchange-level fines, SEBI may appoint an adjudicating officer to hold an inquiry and impose monetary penalties, drawing on its powers under the Securities and Exchange Board of India Act, 1992 and the Securities Contracts (Regulation) Act, 1956.

The RIL matter illustrates the penalty route; many smaller orders illustrate the routine exchange-fine route for late intimations of board outcomes that missed the thirty-minute or three-hour window. Compliance officers and key managerial personnel can be proceeded against individually, reinforcing that the duty is not merely the abstract company’s but rests on identifiable officers. The disclosure of any such fine or penalty imposed on the entity is itself a material event under the 2024 amendment, which set thresholds — broadly, Rs 1 lakh or more imposed by a sectoral regulator and Rs 10 lakh or more by any other authority — above which the penalty must itself be disclosed within twenty-four hours.

Building a Trading-Hours Compliance Architecture

For practitioners, the lesson of the timeline regime is that compliance must be engineered in advance, not improvised after the event. A robust architecture has several features. First, a board-approved materiality policy under Regulation 30(4), with designated key managerial personnel authorised to take the materiality call in real time. Second, pre-drafted intimation templates for every foreseeable board outcome, so that the thirty-minute or three-hour window can be met mechanically. Third, an escalation protocol defining when an officer is treated as having become “aware through a credible source”, anchoring the start of the twelve-hour and twenty-four-hour clocks.

Fourth, a rumour-response playbook aligned to Regulation 30(11) and the Industry Standards Note, with monitoring of price movements during trading hours and a clear chain of authority to confirm or deny within the day. Fifth, disciplined website hosting under Regulation 30(8) so the disclosure record is preserved. Together these turn an unforgiving stopwatch into a manageable routine. The broader compliance calendar and the role of the board in supervising it are addressed in Common Obligations of Listed Entities, and the full set of chapters is collected on the SEBI LODR notes hub.
