Price around the results
Revenue grew, but profit conversion weakened
In the consolidated Q4FY26 results, revenue increased 13.34% year on year, but expenses grew 47.68%, limiting operating-profit growth to 6.65%. Higher interest expense, up 8.43%, and a 2.32% decline in pre-tax profit left net profit almost unchanged despite the lower tax rate.
Margin remains above peers but has not recovered to last year's level
Operating margin narrowed 4.94 percentage points year on year because costs grew faster than revenue, and fell a further 1.00 percentage point sequentially as expenses rose 6.91% against 1.85% revenue growth. At 78.76%, the margin was 19.35 percentage points above the 59.41% median for 52 Financial Services peers that had reported the quarter. Other income was negative and contributed -0.83% of pre-tax profit, so reported earnings were not supported by a positive non-operating contribution.
Sequential profit improved, but margin momentum turned lower
Net profit rose 2.37% sequentially as pre-tax profit increased 6.39%, while interest expense fell 1.03%. The tax rate rose 2.92 percentage points from Q3FY26, partly offsetting the pre-tax improvement. Operating margin had recovered from 76.21% in Q1FY26 to 79.76% in Q3FY26, making the Q4 decline the first break in that three-quarter recovery.
Five-session decline was out of line with the stock's usual reaction
The stock fell 2.41% on the results date and 5.41% after five sessions, underperforming its typical post-results move of 1.97% in absolute terms. Its previous eight result reactions were positive six times and negative twice, so this response was weaker than the stock's recent pattern. The results-date volume was 2.07 times the reference level, with a corporate-action overlap.
