Overview by Business Division
Resources, Energy and Environment
Operating profit declined due to deteriorating revenue of overseas subsidiary companies in the carbon solution business. In FY2025, operating profit is projected to increase due to improved profitability of lifecycle businesses, stable earnings in the nuclear energy business, and improved profitability of the power systems business.
