New results from electron-positron heavy-flavor factories

The electron-positron heavy-flavor factories — BaBar, Belle, Belle~II, and BESIII — continue to deliver a broad and sensitive physics program. I report selected highlights presented at ICHEP 2026, covering neutral- and charged-current $B$ processes, tests of lepton-flavor universality in $b\to c\mathrm{\ell }\nu$ transitions, precision measurement of Cabibbo–Kobayashi–Maskawa matrix elements, and hadron spectroscopy.
