On May 14, 2024, we announced our '24 Mid-Term Business Plan covering FY 2024 through FY 2026 as a phase of accelerated growth toward realizing our FY2030 Target Position. Under this plan, we have set key performance indicators (KPIs) for profitability, capital efficiency, capital investment, shareholder returns, and ESG, and are actively working toward their achievement.
