| Lock-in ends for the first 50% (30 days) | 16 Dec 2025 |
| Lock-in ends for the remaining 50% (90 days) | 14 Feb 2026 |
Anchor investors are large funds that buy the day before the IPO opens. SEBI locks in half their shares for 30 days from the allotment and the rest for 90 days; they can sell from the next trading day. Traders watch these dates because extra selling can come in.
