On March 23, 2023, Kevin Yankton, Chief Accounting Officer of Twist Bioscience Corporation, provided notice of his resignation from the Company effective May 19, 2023, to pursue other interests. Mr. Yankton's resignation is not a result of any disagreement with the Company on any matter relating to the Company's financial reporting, operations, policies or practices. The Company has initiated a search for Mr. Yankton's successor and, in the interim, has engaged an expert financial consultant who will report to James Thorburn.

Mr. Thorburn will serve as the Company's principal accounting officer until a successor to Mr. Yankton is appointed, in addition to his current role as the Company's Chief Financial Officer.
