Earlier this month, brokerage firm HDFC Securities picked the Suzuki-backed stock as its fundamental pick. The brokerage sees the stock surging up to ₹513 in a bull case scenario over the next 2-3 quarters. As per the firm, the Ministry of Road Transport and Highways’ mandate that requires the installation of air conditioning systems in the cabins of motor vehicles falling under categories N2 and N3 (trucks) is a positive trigger for the stock. This mandate applies to vehicles manufactured from Oct. 1, 2025. The mandate was officially notified on Sunday and also seems to be another reason for the stock’s massive surge today.

As per the brokerage, the automotive component manufacturer is currently in the advanced stages of negotiations with original equipment manufacturers (OEMs) and is actively analyzing the specifications for AC systems to be applied in compliance with this regulation for trucks in these categories.

Price Action: Subros’ share price was up 11.17% to trade at ₹500.65 in the early hours of trading on Monday.
