Price around the results
Sequential growth came with weaker operating leverage
Consolidated revenue rose 33.91% QoQ, but expenses increased faster at 36.89%, reducing operating margin by 1.82 percentage points. Operating profit still grew 20.46%, but the cost mismatch marks a weaker conversion of revenue growth into operating earnings. Year on year, the pressure was milder: expenses grew 5.81% against revenue growth of 5.44%, trimming margin by 0.29 percentage points.
Other income and tax changes shaped reported profit
Other income accounted for 46.52% of pre-tax profit, making reported earnings less dependent on operating profit than the headline growth suggests. Sequentially, other income fell 52.17%, driving a 16.39% decline in pre-tax profit despite 20.46% operating-profit growth. The tax rate fell 6.45 percentage points QoQ, which limited the decline in net profit to 8.71%; year on year, the tax rate rose 2.79 percentage points and net profit grew only 3.71%.
Margin is in its third straight quarterly decline
Operating margin has fallen from 20.14% in Q2FY26 to 19.45% in Q3FY26, 18.14% in Q4FY26 and 16.32% in Q1FY27. CESC's margin was 14.77 percentage points below the 31.09% Utilities median among 24 companies that had reported, placing it eighth from the bottom.
The market reaction was positive but smaller than usual
The stock gained 1.40% on the results day, with a 1.56% move relative to the market and volume at 3.56 times the reference level. That reaction was modest against CESC's recent results history: four of the past eight reactions were positive and four negative, with a 4.02% median absolute move.
