Thermax Gains US Data Center Deal Amid 112% Surge in Q4 Order Inflows

Market snapshot: Thermax Limited is witnessing a significant structural pivot as it expands into the high-growth data center cooling and infrastructure vertical. The recent procurement of a boiler pressure parts order for a US-based data center, coupled with a record-high order backlog of ₹13,604 crore, positions the company as a key beneficiary of global industrial capex.

Data Snapshot

• Order Backlog: ₹13,604 crore (up 27% YoY)
• Q4 Order Inflow: ₹4,490 crore (up 111.89% YoY)
• Q4 Revenue: ₹3,428 crore (up 12.5% YoY)
• Special Dividend: ₹6 per share (60th Anniversary)

What's Changed

• Thermax has transitioned from traditional industrial boilers to specialized energy solutions for the data center industry.
• The order booking velocity has more than doubled in the last quarter, jumping from ₹2,119 crore to ₹4,490 crore.
• Global reach is expanding beyond standard exports to technical components for US infrastructure projects.

Key Takeaways

• Record order book provides revenue visibility for the next 2-3 years.
• Data center vertical is emerging as a significant high-margin driver.
• Domestic private capex and international demand are simultaneously peaking.
• Strong cash position with consolidated PAT rising 18.7% in the most recent quarter.

SAHI Perspective

Thermax's ability to penetrate the US data center market with specialized boiler parts signifies a major technological validation. While traditional thermal projects (like the ₹1,600 crore Central India win) remain the bedrock, the move into AI-driven infrastructure cooling and specialized components marks a shift toward higher-value engineering. Investors should note the significant delta in order booking as a lead indicator for FY27 revenue acceleration.

Market Implications

The surge in order inflows suggests a broad-based recovery in industrial capex. Within the sector, Thermax is leading the engineering-heavy equipment segment. Capital allocation remains efficient, evidenced by the special dividend and recent 51% acquisition of AI-firm ExactSpace to digitalize industrial operations.

Trading Signals

Market Bias: Bullish

Record order backlog of ₹13,604 crore and 112% growth in quarterly inflows provide a massive execution runway. Positive bias is supported by a 19% sequential PAT increase and expansion into the US data center segment.

Overweight: Industrial Engineering, Capital Goods, Green Energy

Underweight: High-debt Infrastructure, Commodity-heavy Manufacturing

Trigger Factors:

• Execution timeline of the ₹1,600 crore boiler order
• Steel and alloy input cost trends
• New orders in the data center cooling vertical

Time Horizon: Medium-term (3-12 months)

Industry Context

The Indian capital goods sector is currently riding a multi-year cycle driven by energy transition and domestic manufacturing (PLI) tailwinds. Data center capacity in India and the US is expected to grow at a CAGR of over 20%, creating a sustained demand for industrial cooling and energy systems.

Key Risks to Watch

• Input cost volatility (Steel and Carbon Steel) impacting margins.
• Execution delays in large-scale ultra-supercritical projects.
• Global supply chain disruptions affecting export orders for pressure parts.

Recent Developments

On May 8, 2026, Thermax reported a consolidated PAT of ₹244.28 crore for Q4 FY26, beating estimates. Earlier in March 2026, its subsidiary TBWES bagged a ₹1,600 crore order for an 800 MW thermal plant. In February 2026, the company acquired a 51% stake in Bengaluru-based AI startup ExactSpace to bolster its digital twin capabilities.

Closing Insight

Thermax is no longer just a boiler manufacturer; it is becoming an energy transition and digital-industrial play with a massive global order runway.
