You are receiving this communication because you hold shares of DuPont de Nemours, Inc. (“DuPont”). DuPont previously announced that it intends to separate its electronics business into an independent public company, Qnity Electronics, Inc. (“Qnity”). To effect the separation, DuPont will distribute all of the then-issued and outstanding shares of Qnity common stock on a pro rata basis to DuPont stockholders as of the close of business on October 22, 2025, the record date for the distribution.
