Corporate Announcement Alerts for NSE and BSE
Corporate announcement alerts for NSE and BSE are only as fast as the disclosure rule behind the announcement. SEBI sets three different clocks in Regulation 30(6) of the LODR Regulations, 2015, running from thirty minutes to twenty-four hours depending on where the event came from. An alert product cannot beat those clocks, and understanding which one applies is the difference between reading a feed well and misreading it.
Definition
A corporate announcement alert
notifies you when a listed company files a disclosure with NSE or BSE for a security you follow. The speed is set by SEBI's rules: thirty minutes after a board meeting, twelve hours for events from within the company, twenty-four hours for events from outside. Source: SEBI LODR Regulations, 2015, Regulation 30(6).
The three disclosure clocks
Regulation 30(6) requires a listed entity to disclose material events to the stock exchanges as soon as reasonably possible, and in any case not later than:
| Clock | Applies to |
|---|---|
| 30 minutes | From the closure of the board meeting in which the decision was taken |
| 3 hours | Where the board meeting closes after normal trading hours but more than three hours before the next trading day begins |
| 12 hours | From occurrence, where the event or information emanates from within the listed entity |
| 24 hours | From occurrence, where the event or information does not emanate from within the listed entity |
| 72 hours | From receipt of notice, for certain non-tax litigation claims held in the company's structured digital database |
Where a board meeting runs over more than one day, financial results must be disclosed within thirty minutes or three hours, as applicable, from the close of the day on which they were considered. Events with their own timelines specified in Part A of Schedule III follow those instead.
The 72-hour branch is a conditional relaxation, not a general one. It applies to claims made against the listed entity under litigation or dispute other than tax, and only where all the relevant information is maintained in the structured digital database required under the SEBI Prohibition of Insider Trading Regulations, 2015.

What this means for how an alert behaves
A results announcement is near-immediate. Board-meeting outcomes carry the thirty-minute clock, and companies routinely file inside it. If you are alerting on results, the feed is close to the event. The prior notice is separate: see how to read a board meeting intimation.
An externally sourced event can be a day old on arrival. A regulatory order, a rating action, a court direction: these do not emanate from within the company, so the clock is twenty-four hours from occurrence. A filing that lands at 4pm may describe something that happened yesterday afternoon, and the company is fully compliant. An alert that presents the filing timestamp as the event time is misleading on exactly these rows.
Late filings announce themselves. Where disclosure is made after the specified timeline, the entity must provide the explanation for the delay along with the disclosure. That explanation is a readable field, and it is worth surfacing rather than stripping.
Deemed material versus judged material
Not every announcement is the same kind of object. Regulation 30 splits Schedule III into two paragraphs, and an alert feed inherits the split.
- Para A of Part A events are deemed material. The company has no discretion: they are disclosed.
- Para B of Part A events are disclosed based on the materiality guidelines in Regulation 30(4), which include whether omission would cause discontinuity in publicly available information, whether omission would likely cause significant market reaction, and a value-based threshold.
The practical consequence for alerting is that Para B coverage varies by company, because the judgement is the company's. Two similar-sized firms can treat the same event differently and both be compliant. See what is material event disclosure and how to read material event disclosures.
What to carry in the alert
- Event time and filing time as separate fields. They are different facts, and the gap between them is regulated rather than accidental.
- The Schedule III category. It tells you whether the disclosure was mandatory or a judgement call.
- The attachment. Announcements carry PDFs, and the substance is usually in the attachment rather than the subject line. An alert that only reads the subject line will describe a filing it has not opened.
- A link back to the exchange filing. Every claim in the alert should be checkable against the original.
What announcement alerts do not replace
They are event notices, not a position record. Who owns the company and how that changed lives in the periodic filings: the shareholding pattern each quarter, bulk and block deals on specific dates, and promoter encumbrance disclosures.

Frequently asked questions
How fast must a listed company disclose a material event?
It depends on the source of the event. Thirty minutes from the closure of the board meeting where the decision was taken, twelve hours from occurrence if the event emanates from within the listed entity, and twenty-four hours if it does not. Source: SEBI LODR Regulations, 2015, Regulation 30(6).
Why do some announcements arrive hours after the event?
Because the regulation allows it. An event not emanating from within the listed entity, such as an order received from an authority, carries a twenty-four hour clock. A company disclosing at hour twenty-three is compliant, so an alert built on exchange filings inherits that delay. Source: SEBI LODR Regulations, 2015, Regulation 30(6)(iii).
What happens if a company misses the disclosure deadline?
It must explain itself in the filing. Regulation 30(6) provides that where disclosure is made after the specified timelines, the listed entity shall, along with such disclosure, provide the explanation for the delay. The explanation is part of the public record. Source: SEBI LODR Regulations, 2015.
Are all corporate announcements material events?
No. Events in Para A of Part A of Schedule III are deemed material and must always be disclosed. Events in Para B are disclosed only if they meet the materiality guidelines the company applies under Regulation 30(4). The two categories behave differently in an alert feed.
