Thermax Q1 FY27: Revenue Up 7%, PAT Down 85%, merger okayed

What Thermax reported in Q1 FY27

Thermax Limited announced its financial results for the quarter ended June 30, 2026, alongside a corporate restructuring update. Consolidated revenue from operations increased to ₹2,303 crore, compared with about ₹2,150 crore in the corresponding quarter of the previous fiscal year. But the quarter was defined by a sharp drop in profitability, with consolidated net profit after tax (PAT) falling steeply year-on-year.

In the material shared, PAT is reported at multiple points as ₹25.2 crore, ₹22 crore, and ₹21.79 crore for the quarter. The detailed metric table listed net profit after tax at ₹21.79 crore versus ₹151.45 crore a year earlier, indicating an 85% decline. Profit before tax also fell sharply to ₹42.14 crore from ₹211.47 crore.

The company’s numbers were approved at the Board meeting held on July 30, 2026, which considered the un-audited standalone and consolidated financial results.

The main driver: a project cost overrun

Thermax attributed the sharp contraction in profitability predominantly to a large revision in project cost estimates. The company flagged a ₹91 crore increase in estimated costs to complete one specific project within its Industrial Infra segment. The cost overrun was presented as the primary factor behind the margin pressure during the quarter.

Separately, the prompt context also notes that despite a 7% increase in revenue, Thermax reported an 85% decline in net profit mainly due to a major project cost overrun in its Industrial Infra business. The narrative across the shared content consistently points to cost and execution pressure rather than a revenue slowdown.

Revenue growth and the order book picture

While profitability weakened, Thermax reported steady top-line growth. Consolidated revenue from operations for the quarter was ₹2,302.73 crore versus ₹2,157.53 crore in Q1 FY26, which the summary pegged at about a 7% year-on-year rise.

Order momentum was stronger than revenue growth. The company reported an order book balance of ₹14,045 crore, up from ₹11,376 crore, a 23% increase. A separate data point in the shared material also states that the company entered the quarter with an order backlog of ₹13,604 crore as of March 31, 2026, before the June 30 order book disclosure.

EPS snapshot mentioned in the shared material

The shared notes also include an earnings-per-share (EPS) data point. EPS for the quarter is stated as 2.24. It compares with 21.68 in the immediately preceding quarter and 13.53 in the same quarter of last year, as per the information provided.

Board approves amalgamation to streamline structure

Alongside quarterly results, Thermax’s Board approved a Scheme of Arrangement and Amalgamation. Under the scheme, two wholly-owned subsidiaries will be merged into the parent company: Thermax Bioenergy Solutions Private Limited (TBSPL) and Thermax Cooling Solutions Limited (TCSL).

The stated intent is to simplify the group structure by consolidating clean energy and cooling businesses directly into Thermax Limited. The shared content describes this as a streamlining exercise rather than a change in control, since both entities are wholly owned.

Market impact and what investors will watch

The quarter sets up a clear split between revenue resilience and profitability stress. Revenue grew, and the order book expanded year-on-year, but the profit line was hit by a single large revision in project cost estimates. That combination often shifts near-term investor focus toward execution quality, project risk controls, and how quickly margins can stabilize.

The scheduled management call on July 31, 2026 is positioned as the key forum for clarifying the cost-overrun context, any segment-level operational pressures, and the implications of merging TBSPL and TCSL into the parent. Separately, the shared material also includes a market commentary noting a trading level of ₹4,454.50 and a resistance zone of roughly ₹4,800 to ₹5,000, which reflects technical observation rather than company guidance.

Conclusion

Thermax reported Q1 FY27 revenue growth to ₹2,303 crore but a sharp year-on-year drop in PAT to about ₹22 crore, driven predominantly by a ₹91 crore increase in estimated costs on an Industrial Infra project. The Board also approved an amalgamation of TBSPL and TCSL into Thermax Limited as part of a group simplification plan. Investors and analysts are expected to seek further detail on project execution and profitability drivers during the July 31, 2026 conference call.
