Bounded FY2025-09-30 consolidated financing-statement extraction. Proceeds from exercise of stock options: 166000000 USD [us-gaap:ProceedsFromStockOptionsExercised]. All 11 financing lines reconcile exactly to reported financing cash flow -4900000000 USD. Cash inflows from common shares, employee plans and option exercises are summed once as displayed on the statement; noncash compensation, withholding payments, preferred and noncontrolling interests are excluded. This review applies only to this issuer and fiscal period. Source limitation: the statement also aggregates other financing cash flows (net -10000000 USD). Their common-equity portion is not separately disclosed here. Issuance is the sum of separately reported common cash-issuance lines, not an independently verified gross total; additional equity flows may be inside those aggregates.
