GP Petroleums Limited reported an 8% year-on-year rise in fourth-quarter profit, aided by improved operating margins and steady demand across industrial and automotive lubricant segments, even as revenue declined amid volatile market conditions.The company posted a profit after tax (PAT) of Rs 9.3 crore for the quarter ended March 31, 2026, compared with Rs 8.6 crore in the corresponding period last year. Revenue from operations fell to Rs 163 crore from Rs 183 crore a year earlier.Ebitda rose to Rs 14.7 crore in the March quarter from Rs 13.2 crore a year ago, while Ebitda margin improved to 9% from 7%.For the full financial year 2025-26, GP Petroleums reported revenue from operations of Rs 643 crore, up 5% from Rs 610 crore in FY25. Annual EBITDA increased to Rs 44.7 crore from Rs 42 crore in the previous year.PAT for FY26 stood at Rs 26.5 crore compared with Rs 26.3 crore in FY25. The company said annual profit was impacted by a wage provision of Rs 3.25 crore, equivalent to about 12% of FY26 PAT.Commenting on the performance, the company said it continued to strengthen its market position across lubricant and process oil categories through operational efficiencies, customer relationships, and an expanding product portfolio.The company said opportunities in demand remain encouraging in industrial lubricants, process oils, and premium automotive lubricants. However, it cautioned that geopolitical tensions and crude-linked raw material volatility toward the end of the March quarter could pose short- to medium-term challenges.“Geopolitical developments have created uncertainty and price volatility, resulting in a sharp increase in crude-linked raw material costs and currency weakness,” the company said.Founded in 1973, GP Petroleums markets lubricants and specialty oils under the IPOL brand and exports to more than 12 countries. The company also has an exclusive partnership with Repsol to manufacture and distribute Repsol-branded lubricants in India.
