The read

Demergers create index housekeeping. Effective July 22, 2026, Triveni Power Transmission lands inside nine BSE indices at a zero price, no divisor tweak. Shareholders get 1 TPTL share for every 3 TRIVENI shares held. A Special Pre-Open Session on the same day will discover TRIVENI's adjusted price. For passive funds tracking these indices, the zero-price addition means no immediate tracking error but eventual adjustment when TPTL begins trading. Nothing regulatory, nothing dramatic — index mechanics doing their job.
