Indian Oil Corporation Ltd. reported revenue of ₹2.66 lakh cr for April to June 2026, +38.5% on the year and +27.9% on the quarter. That is faster than this quarter has grown in recent years (−1.6% on average), so the year-on-year number is not just the season. It is the highest quarterly revenue in the last 12 quarters on record. Over the last four quarters revenue comes to ₹8.58 lakh cr, +13.5% on the four before.
Operating profit (EBITDA) was ₹4,062 cr, a margin of 1.5%, −537 bps on the year and −1,038 bps on the quarter. It is the narrowest margin of the last 8 quarters (range 1.5% to 11.9%). Operating costs grew +46.5%, faster than revenue at +38.5%, so operating profit grew less than sales.
The company swung to a net loss of ₹1,141 cr from a profit of ₹6,808 cr a year earlier, with earnings per share of −₹1.15. Profit before other income, one-offs and tax fell 129.6%, so 13 points of the headline growth came from outside the core business. Profit over the last four quarters totals ₹35,728 cr, +111.7% on the four before.
Refining and marketing profits swing with crude and product margins, and inventory gains or losses can move a single quarter sharply. The quarterly statements do not carry refining margins, throughput and inventory gains or losses; those come with the filing read.
On earnings per share of ₹23.84 over the last four quarters, the stock at ₹129.68 trades at 5.4 times trailing earnings.
Written from the quarterly statements. The filing read adds the balance sheet and cash flow, the auditor's review, segment results, one-off items line by line and what management said on the call.
