"At 30-day unlock" and "At 90-day unlock" compare NSE's official close on the first trading day on or after allotment + 30 and + 90 days (the first day the shares can be sold) with the issue price. "–" means there is no figure: the date has not come yet, the IPO opened before 1 April 2022 (no 90-day lock-in then), or its allotment date is not on record.
