Price around the results
Revenue growth accelerated, but profit conversion lagged
Consolidated revenue rose 69.21% year on year and 33.10% sequentially, lifting operating profit by 49.46% year on year and 21.69% sequentially. Net profit grew more slowly at 36.16% year on year because the tax rate increased by 2.23 percentage points to 26.86%. Other income contributed 8.19% of pre-tax profit, so it supported earnings but was not the main profit driver.
Costs caused the quarterly margin squeeze
Expenses grew 73.78% year on year against 69.21% revenue growth, reducing operating margin by 2.19 percentage points. Sequentially, expenses also grew faster than revenue, at 35.63% versus 33.10%, taking margin down 1.56 percentage points. Lower interest costs helped, falling 44.00% year on year and 46.15% sequentially, but did not offset the operating-cost pressure.
Margin fell for a fourth straight quarter
Operating margin has declined in every quarter from 18.80% in Q4FY25 to 16.61% in Q4FY26, including the 18.51%, 18.26% and 18.17% readings in the intervening quarters. Even after the decline, TD Power's margin was 0.95 percentage points above the 15.66% median among 71 Industrials peers that had reported the quarter. The year-on-year comparison is more informative here because the revenue increase was substantially larger than the sequential increase.
Order momentum raises execution and capacity requirements
Management said demand remained very strong across the generator business and that the order pipeline was extremely buoyant. It said order inflow had exceeded Rs 600 cr per quarter for the past two quarters and was approaching an average of about Rs 650 cr, while Q4FY26 inflow rose 61.00% year on year to Rs 6,665 million, with 79% from exports. The company told analysts that this pace was putting pressure on execution and that investments would be needed for FY28 demand, including significant capacity additions for machining very large components.
The market reaction was unusually large for TD Power
The stock rose 10.75% on the results day and was up 9.38% after five sessions, with trading volume at 6.74 times the reference level. This was notably larger than the stock's 3.72% median absolute move after its past eight results, when it rose seven times and fell once. The day-one move was therefore an unusually strong positive reaction relative to its own results history.
