Haemonetics Corporation

Item 7.01  Regulation FD Disclosure On August 14, 2026, Haemonetics Corporation (the “Company”) entered into a supply agreement with CSL Plasma Inc. (“CSL”) pursuant to which CSL may utilize the Company’s NexSys PCS® devices with Persona® PLUS technology and purchase related disposables in the United States. The supply agreement is non-exclusive and does not contain minimum purchase commitments. Haemonetics anticipates CSL to transition a portion of its U.S. plasma collection centers to the Company’s devices and disposables, but the scope and timing of implementation have not yet been determined. Accordingly, the Company is not updating its previously issued fiscal 2027 guidance at this time. The Company expects to provide an update regarding the anticipated impact of the agreement on its fiscal 2027 financial results in connection with its second fiscal quarter earnings call in November 2026. The foregoing information in this Item 7.01 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, regardless of any general incorporation language in such filing.
