Prostarm Info Systems IPO Delivers Spark, 19% Premium On Listing - Check Price

Shares of Prostarm Info Systems Limited made a remarkable debut on the stock exchanges on June 3, 2025, opening at Rs 125 on the BSE — a 19.04% premium over its issue price of Rs 105. On the NSE, the stock was listed at Rs 120, registering a 14.28% gain.

The listing came as a positive surprise, especially as the company's grey market premium (GMP) had seen a steep drop from Rs 20 to Rs 12 per share ahead of the listing, as per market tracker.

This 40% decline in GMP had dampened expectations, suggesting listing gains of only 10–11%. However, the final listing exceeded those projections, offering better-than-expected returns for investors.
