Chennai Petroleum Corporation Limited (CPCL) shares plunged 6.67% to Rs 710.80 in Wednesday’s session following the announcement of disappointing Q1 FY26 results. The stock dropped Rs 50.80 from its previous close of Rs 761.60, hitting an intraday low of Rs 704.45.

The company reported a revenue of Rs 18,693 crore for the quarter ended June 30, 2025, down 8.1% from Rs 20,365 crore in the same period last year. The decline was attributed to lower product realisations and weaker refinery throughput.

CPCL posted a net loss of Rs 40.10 crore in Q1 FY26, a stark contrast to the net profit of Rs 357.03 crore recorded in Q1 FY25. This reversal was driven by a sharp rise in excise duty expenses, which climbed to Rs 3,871 crore from Rs 3,266 crore YoY, and a loss of Rs 83.16 crore due to inventory valuation changes.

Total expenses for the quarter stood at Rs 18,772.80 crore, slightly exceeding total income of Rs 18,692.74 crore, leading to a pre-tax loss of Rs 80.06 crore.

As of the latest update, the company’s market capitalization stands at Rs 1.05 lakh crore.
