Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES The Company is a party to various legal proceedings and claims arising out of the ordinary course of its business. The Company believes that, except for those matters described below, there are no other proceedings or claims pending against it the ultimate resolution of which could have a material adverse effect on its financial condition or results of operations. At each reporting period, management evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under ASC 450, Contingencies, for all matters. Legal costs are expensed as incurred. In the fourth quarter of fiscal 2021, a putative class action complaint was filed against the Company in the Circuit Court of Cook County, Illinois by Mary Crumpton, on behalf of herself and similarly situated individuals. The Company removed the case to the United States District Court for the Northern District Illinois. See Mary Crumpton v. Haemonetics Corporation, Case No. 1:21-cv-1402. In her complaint, the plaintiff asserted that between June 2017 and August 2018 she donated plasma at a center operated by one of the Company’s customers, that the center required her to scan her fingerprint on a finger scanner that stored her fingerprint to identify her prior to plasma donation, and that the Company’s eQue donor management software sent her biometric information to a Company-owned server to be collected and stored in a manner that violated her rights under the Illinois Biometric Information Privacy Act (“BIPA”). The plaintiff sought statutory damages, attorneys’ fees and injunctive and equitable relief. During the second quarter of fiscal 2024, the Company entered into a Memorandum of Understanding providing terms that would resolve the litigation and recorded an additional loss contingency related to this matter. In the third quarter of fiscal 2024, the parties requested preliminary court approval of a final settlement agreement, which was granted in February 2024, and the Company recorded an immaterial additional loss contingency related to settlement administration, resulting in an accrual of $8.7 million within other current liabilities in its consolidated balance sheets. In March 2024, administration of the settlement through the third-party administrator commenced and, in April 2025, the administrator notified the parties that distribution of the final settlement funds was underway and that administration would formally close 90 days thereafter. In the first quarter of fiscal 2025, the Company issued payment of the $8.7 million settlement amount following the court’s final approval of the settlement agreement and dismissal of the matter with prejudice. During the fourth quarter of fiscal 2024, a complaint was filed in the U.S. District Court for the District of Delaware by Knoninklijke Philips N.V. and IP2IPO Innovations, Ltd. (together, the “Plaintiffs”) against OpSens, OpSens Medical, Inc., a wholly-owned subsidiary of OpSens, and Haemonetics (1:24-cv-00206-CFC). The complaint alleges, inter alia, that OpSens’ interventional cardiology systems, including its OptoWire and OptoMonitor technology, infringe a single patent held by the Plaintiffs and seeks both injunctive relief and damages. A claim construction hearing in the matter is scheduled to take place in the first quarter of fiscal 2026. The Company believes it has valid and meritorious defenses to the complaint and plans to vigorously defend against the complaint. The Company recorded loss contingencies related to this matter in the first quarter and fourth quarter of fiscal 2025, which did not have a material impact on its Condensed Consolidated Financial Statements. During the first quarter of fiscal 2026, the Company filed a complaint against Terumo BCT in U.S. District Court for the District of Colorado. The complaint alleges that Terumo BCT infringes the Company’s intellectual property rights with respect to its donor-centric blood plasma collection patents, as embodied in our NexSys PCS® with YES® technology and NexSys PCS with Persona® technology. While we will incur costs in the course of pursuing this claim, and the outcome of litigation is inherently uncertain, we believe this is a necessary and appropriate action to safeguard our innovations, protect our intellectual property, and further the growth and development of our business. Product Recall In August 2023, the Company issued a voluntary recall of certain products within the Whole Blood portion of our Blood Center business unit sold to customers in the U.S. and certain foreign jurisdictions. As of March 29, 2025, the Company has recorded cumulative charges of $6.8 million related to inventory, returns and customer claims associated with this recall. Substantially all outstanding claims have been paid as of March 29, 2025.
