Price around the results
Revenue growth did not translate into operating profit
Aether Industries reported consolidated revenue growth of 27.03% YoY in Q4FY26, but operating profit increased only 3.80% because expenses rose 38.55%. Net profit grew 7.38% to Rs 54.01 cr, as the lower tax rate partly offset higher interest and depreciation. The result was filed after market close on 15 May.
Q4 reversed the Q3 margin peak
Operating margin fell 7.78 percentage points QoQ to 27.10%: revenue declined 3.78% while expenses increased 7.70%. This reversed the rise to 34.88% in Q3FY26 and left margin below the 31.50% recorded in Q1FY26 and 31.99% in Q2FY26. Interest expense rose 56.63% QoQ, while the tax rate fell 5.43 percentage points; other income contributed 14.54% of pre-tax profit, so net profit was not entirely operating-led.
Margin remained above the reported commodities peer median
Aether's 27.10% operating margin was 8.33 percentage points above the 18.77% median for the 51 commodities-sector peers that had reported the same quarter. The sector comparison provides some context for the sequential deterioration: Aether's margin fell sharply, but remained above the peer midpoint.
