Thermax Finalizes Exactspace Acquisition to Enhance AI Services

Thermax Limited announced on April 9, 2026, that it has finalized the acquisition of Exactspace Technologies Private Limited, increasing its ownership to 51% on a fully diluted basis. This transaction officially makes Exactspace a subsidiary of Thermax. The definitive agreements for the acquisition were initially signed on February 27, 2026.

Enhancing Digital Capabilities

The acquisition is a strategic step in Thermax's digital transformation strategy, aimed at boosting its service offerings. By integrating Exactspace's expertise in Artificial Intelligence (AI) and Industrial Internet of Things (IoT) solutions, Thermax plans to enhance its predictive maintenance capabilities. The company aims to provide more comprehensive end-to-end asset support to its manufacturing clients through these advanced technologies.

Building on Previous Investment

Thermax had previously signaled its confidence in Exactspace's AI and IoT technologies by leading a $1.4 million seed funding round in March 2022. This increased stake allows Thermax to leverage Exactspace's advanced AI-driven predictive asset maintenance, process optimization, and analytics for failure analysis, augmenting Thermax's existing service portfolio.

Integration and Future Options

With Exactspace now a subsidiary, Thermax gains direct access to these advanced AI and IoT capabilities. The company is poised to offer integrated digital solutions for predictive asset maintenance and performance optimization, strengthening its position in the evolving industrial services market. Thermax also holds an option to acquire the remaining 49% stake in Exactspace after three years, a development investors will monitor.

Key Considerations

While the acquisition strengthens Thermax's digital push, integration will be key. Seamlessly applying new AI capabilities across Thermax's diverse industrial segments will be crucial for realizing their full potential. Separately, Thermax is addressing a recent Goods and Services Tax (GST) penalty of ₹3.14 crore for alleged incorrect HSN classification of goods, for which it plans to file an appeal.

Market Context

Thermax operates in a competitive sector alongside companies such as ABB India Ltd, Siemens Ltd, and Bharat Heavy Electricals Ltd (BHEL). These peers are also actively pursuing digitalization and sustainability in their industrial technology, automation, and energy solutions.

Financial Snapshot

Exactspace Technologies reported revenue of ₹6.21 crore in the fiscal year 2025. The total cost for Thermax's initial 51% stake acquisition was ₹30.48 crore.

What Investors Will Track

Investors will be looking at how effectively Thermax integrates Exactspace's technology into its operations and the resulting impact on revenue and profitability. Tracking the company's progress in offering enhanced, end-to-end asset support and advanced digital solutions will also be key.
