The sell-off was immediate and punishing. Shares of Thermax Ltd. crashed 17% on Friday, November 6, tumbling toward 52-week lows after the energy and environment engineering firm missed earnings projections by 26%. Institutional desks offloaded holdings in early morning trade, punishing a quarterly report where top-line expansion failed to protect profitability.
Consolidated net profit slipped 4.2% year-on-year to ₹115 crore for the July–September quarter, down from ₹120 crore during the corresponding period last year. Revenue told a contrasting story—rising 11.4% to ₹2,756 crore against ₹2,474 crore twelve months earlier. Operating profit also pushed higher, with earnings before interest, tax, depreciation, and amortisation (EBITDA) gaining 12.8% to ₹194 crore. Yet operating margin remained essentially frozen at 7%, barely budging from the 6.9% logged a year ago.
| Financial Metric | Q2 Current Year | Q2 Previous Year | YoY Change |
|---|---|---|---|
| Revenue | ₹2,756 crore | ₹2,474 crore | +11.4% |
| EBITDA | ₹194 crore | ₹172 crore | +12.8% |
| EBITDA Margin | 7.0% | 6.9% | +10 bps |
| Net Profit | ₹115 crore | ₹120 crore | -4.2% |
Management attributed the earnings contraction to surging input costs and a disadvantageous product mix inside its core Industrial Products business. That division delivered a 10.3% year-on-year rise in gross revenue. But margins told a grimmer story—earnings before interest and taxes (EBIT) margin collapsed by 370 basis points year-on-year to 6.1%, matching the previous quarter's weak print and wiping out pricing leverage. Balance sheet pressures intensified further when Thermax booked an additional impairment provision of ₹15 crore inside its Green Solutions division.
But one operational bright spot emerged from Industrial Infrastructure. The capital goods division grew revenue by 13.6% year-on-year, driving its EBIT margin up to 5.6%. That marked a sharp turnaround from a negative 8.3% margin logged in the preceding three months and flat 0% profitability recorded in the prior-year period.
The operational recovery in infrastructure could not offset the broader profit drag. Thermax stock had settled Thursday at ₹3,313, registering a modest 0.94% daily gain and leaving the scrip up roughly 8% across calendar year 2026. Friday's 17% drop erased those cumulative gains in a single session as market participants recalibrated earnings trajectories for the remaining fiscal quarters.
