Despite the impact of rising crude oil prices, strong contributions from trading and other activities led to a substantial increase in operating income. Estimates and reclassifications related to the transition to IFRS are reflected, and profit before tax and net income attributable to owners of the parent also increased significantly.\n\n### Outlook and Financial Position\nThe effects of the transition to IFRS are expected to continue, prompting revisions to full-year earnings guidance. Capital structure changes include increases in current liabilities and interest-bearing debt, with total assets approximately 6,251,277 million yen. Cash and cash equivalents declined to 303,600 million yen at the interim period end.","jir_financial_highlights":"Revenue: 5,055,927 million yen (Year-over-Year (YoY) increase of 33.6%)\nOperating Income: 425,675 million yen (YoY +644.6%)\nProfit before Tax (Interim): 449,862 million yen (YoY +510.9%)\nNet Income Attributable to Owners of Parent (Interim): 322,439 million yen (YoY +422.5%)\nNumber of Outstanding Shares (At Period End): 1,223,217,590 shares (Decreased from 1,288,747,390 shares at the end of the prior fiscal year)","jir_category":"","jir_hashtags":"#IdemitsuKosan, #Earnings, #IFRSTransition","jir_key_figures":"Revenue: 5,055,927 million yen (YoY increase of 33.6%)\nOperating Income: 425,675 million yen (YoY +644.6%)\nNet Income Attributable to Owners of Parent (Interim): 322,439 million yen (YoY +422.5%)","jir_meta_title":"Idemitsu Kosan Co.,Ltd. \u2014 FY2027 Q2 Financial Summary | Revenue Exceeds \u00a55 Trillion, Significant Profit Growth","jir_meta_description":"Summary of Idemitsu Kosan Co.,Ltd.'s Q2 results under IFRS: revenue exceeded 5,055,927 million yen, operating income approximately 425,675 million yen, and net income attributable to owners of the parent about 322,439 million yen, significantly surpassing the prior year.
