AI summary

Indian Oil Corporation has informed the stock exchanges that its Board of Directors will meet around 6th-7th March 2026 to consider declaring the 2nd Interim Dividend for the financial year 2025-26. This follows the first interim dividend already declared earlier in the fiscal year. As per insider trading rules, the trading window for dealing in IOCL shares will remain closed for designated insiders from 27th February 2026 until 48 hours after the board meeting concludes and the dividend announcement is filed with the exchanges. No specific dividend amount has been disclosed yet — it will be decided at the board meeting.

Likely market impact

The announcement signals continued shareholder returns from IOCL through a second interim dividend in FY26, which is generally positive for income-focused investors. The actual impact on stock price will depend on the dividend amount declared at the board meeting. The trading window closure is a standard regulatory formality and does not affect retail investors' ability to trade.
