Capital returns are aggressive (and continuing), with buybacks supported by strong earnings - Q3 buybacks: repurchased 14.8m shares for ~$1.4b. - Through 9 months: repurchased ~109% of net income in company shares (i.e., payout >100% on that metric). - More in October: management indicated ~$100m additional buybacks through last night. - Balance of buybacks vs investing: priority remains investing in the business, but they see excess capital in a transitioning/growth-constrained environment; inorganic opportunities described as strategic M&A, not mainly a capital management lever.
