Nitin Castings Limited has announced the closure of its trading window for insiders, designated persons, and their immediate relatives. This closure, effective from April 1, 2026, is to prevent insider trading ahead of the declaration of financial results for the quarter and year ended March 31, 2026. The window will reopen 48 hours after these results are made public. The company will separately announce the date of the board meeting where these financial results will be considered. This ensures fair trading practices for all stakeholders.
