BNY (BNY): Delivering on all fronts as organic growth, NII and margins move higher; reiterate Buy

Following BNY's 3Q26 beat, we reiterate our Buy rating on the stock. The firm continues to deliver on multiple fronts - broad-based organic fee growth, upside to NII, continued progress on operating leverage. Management's updated 2026 outlook (total revenue growth to 12%-13%; NII +15%, and expenses 7%-8% range, now implying ~500bps of positive operating leverage) implies ~2% upside to Street's 4Q PPNR estimate. We think the firm's beat-and-raise dynamics remain intact, with a mid-teens EPS CAGR algo proving durable. We see: 1) accelerating organic fee growth momentum, with organic fee growth accelerating to 5% over the next 12-18 months and fee growth of ~6-7% in 2027/2028, above Street's 4-5%; 2) robust NII outlook, with the raised ~15% y/y guide implying 4Q NII of ~$1.45bn, which appears conservative given QTD deposit trends and a ~150-200bps yield pickup on ~$5bn/qtr of securities roll-off; we model ~16% NII growth in 2026 and NIMs of ~150bps in 2027;
