Thermax’s share price jumped 7% as the company considers selling a majority stake in its renewable energy subsidiary, First Energy, signaling potential strategic shifts in its operations.

Market Reaction to Stake Sale Buzz

Thermax’s share price movement reflects a significant response to the news of a potential stake sale in First Energy, its renewable energy arm. The stock rose to ₹3,350 during intra-day trading on Friday, rebounding from a 39% decline since July 2026. This uptick comes as investors react positively to the prospect of a strategic investor stepping in to bolster the subsidiary’s operations.

The stock’s performance has been volatile, with a 52-week high of ₹5,277 recorded on June 29, 2026, and a low of ₹2,744.20 on December 8, 2025. As of 10:36 AM, the stock was trading 4.5% higher at ₹3,280.60, outperforming the BSE Sensex, which rose by 1.13%.

Details of the Potential Stake Sale

Reports indicate that Thermax is exploring the sale of more than 51% of First Energy, which has an estimated enterprise value of ₹3,000 crore. The subsidiary operates approximately 800 MW of renewable capacity and offers various power solutions to commercial and industrial customers, including hybrid and battery storage options.

However, First Energy has faced execution challenges, including right-of-way issues and coordination with state governments. In its FY26 annual report, Thermax acknowledged that the subsidiary had underperformed expectations and was implementing corrective measures. The involvement of a strategic investor could provide the necessary capital and operational support to address these challenges and accelerate growth in the renewable energy market.

Implications for the Renewable Energy Sector

The potential stake sale comes at a time when India is experiencing a capex super cycle, particularly in sectors driven by policy initiatives, such as renewable energy and infrastructure. Analysts at InCred Equities note that this cycle is distinct from previous consumption-led cycles, focusing on new-age areas like transmission and distribution, green hydrogen, and data centers.

The ongoing geopolitical tensions in the Middle East are expected to accelerate India’s energy independence goals, with a target of achieving 900 GW of renewable energy capacity by 2036. This backdrop could favor companies like Thermax that are positioned to capitalize on the growing demand for renewable energy solutions.
