Impact Assessment

This is a high-impact corporate action affecting all shareholders and trading members dealing in DEV LABTECH VENTURE LTD. The combined sub-division and bonus issue quadruples the number of shares outstanding, reducing the face value from Rs.10/- to Rs.5/- per share and theoretically adjusting the market price proportionately. The market lot increase from 1,000 to 4,000 reflects this 4x multiplication. Traders and clearing members must update their systems before 15 May 2026 to avoid settlement failures. The invalidation of the existing ISIN requires immediate action from depositories and members to transition to the new ISIN once announced.
