AI summary

Seven promoter family members and PACs filed shareholding disclosures as of March 31, 2026. Sundar Iyer (promoter) holds 45,56,157 shares (43.39%), remaining the largest shareholder. Combined holding of Sundar Iyer, Vanaja Sundar Iyer (7.81%), Karthik Sundar Iyer (11.85%), Ebrahim Rangoonwala (0.95%), Krishnan Muthukumar (0.21%), and Shridhar Iyer (0.21%) totals approximately 64.42%. Siddharth Iyer disclosed he sold his entire shareholding during December 2019 - January 2020, now holding NIL shares. This is a routine regulatory filing under SEBI Takeover Regulations.

Likely market impact

No immediate impact on stock price as this is a disclosure of existing holdings. Sundar Iyer's individual holding at 43.39% is below the 50% threshold, indicating no single promoter has majority control. Siddharth Iyer's exit from the promoter group happened years ago.
