OCC (Options Clearing Corporation) – Information Memos

#58458

Effective February 27, 2026 the Options Clearing Corporation announced that the National Securities Clearing Corporation will no longer accept settlement of RAPT Therapeutics option exercises. All RAPT option exercises and assignments will therefore settle on a broker‑to‑broker basis, with the standard deliverable of 100 shares. No exercise restrictions are imposed, but the settlement pathway has shifted away from the NSCC clearing model, potentially extending settlement timelines for pending exercises.
