AI summary

His individual holding rose from 17,00,256 shares (8.28%) to 17,09,493 shares (8.33%). The acquisition was disclosed on 12th December 2025 under SEBI Takeover Regulations. The filing also lists Persons Acting in Concert (PAC) including Kandarp Amin, Archana Amin, Archit Amin, Shimoli Amin, and Manini Amin, though only Suchit Amin's individual transaction is reported. No encumbrance (pledge/lien) activity is involved in this deal.

Likely market impact

This is a small, incremental promoter purchase — a modest show of confidence by Suchit Amin in the company. The size (just 0.05%) is unlikely to materially move the stock price, but it signals continued promoter buying at current levels.
