AI summary

Power Grid Corporation has informed the exchanges that its trading window will remain closed from March 17, 2026 to March 21, 2026 (both days inclusive), reopening on March 22, 2026, in line with SEBI's insider trading regulations. The closure coincides with a Board meeting scheduled for March 19, 2026, where the Board will consider and approve a revised proposal for the merger/amalgamation of 28 wholly owned subsidiaries (WOS) into 2 other WOS. This new proposal supersedes an earlier plan approved by the Board to merge 11 WOS into 2 other WOS, indicating a significantly expanded consolidation plan.

Likely market impact

This is a routine compliance announcement signalling an upcoming corporate event rather than an immediate market-moving development. The expanded scope of subsidiary consolidation (28 WOS instead of 11) could have long-term implications for the company's organisational structure and efficiency, but the actual impact will depend on the final scheme approved at the Board meeting on March 19.
