Saptak Chem and Business has announced the closure of its trading window for designated persons, including promoters, directors, key management, and their immediate relatives. This closure starts from October 1, 2025, and will remain in effect until 48 hours after the company declares its financial results for the quarter ended September 30, 2025. This measure is implemented to prevent insider trading ahead of financial disclosures. The company also stated that the date for the board meeting to approve these results will be announced subsequently. This ensures fair play and protects shareholder interests by regulating trading activity.
