Net income is profit attributable to owners of the parent. The shaded row is the company's own forecast, not a JII estimate.
Standalone quarters — the last 12
Standalone quarters derived from each period's own year-to-date disclosure (JP GAAP, consolidated, ¥M; net profit is profit attributable to owners of parent). The four quarters reconcile to each fiscal year within ¥1M of rounding. FY3/25 Q4 net profit of ¥2,601M includes non-operating and extraordinary items (equity-method income and securities gains) that lifted full-year net profit 35% on 12% operating-profit growth.

Where the profit comes from
Segment figures from the segment notes of the annual securities reports and the FY3/26 tanshin (JP GAAP, ¥M; revenue is external-customer sales). Segments are sales regions, not product lines. Segment profits do not sum exactly to group operating profit because inter-segment eliminations sit in an adjustment line (FY3/26: +¥61M). Per-quarter segment series are sparse after Japan's 2024 disclosure reform; the FY3/26 tanshin discloses segments on a full-year basis only.
