Reports on Internal Control

Management’s Annual Report on Internal Control over Financial Reporting

The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended. The Company’s internal control system was designed to provide reasonable assurance to the Company’s management and Board of Directors regarding the preparation and fair presentation of published financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company’s management assessed the effectiveness of its internal control over financial reporting as of March 28, 2026. In making this assessment, the management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework (2013 framework). Based on the Company’s assessment, the Company’s management believes that its internal controls over financial reporting were effective as of March 28, 2026.

The Acquisition of Vivasure

On January 9, 2026, the Company completed its acquisition of Vivasure. In accordance with the SEC Staff’s interpretative guidance for newly acquired businesses, the Company is permitted to omit an assessment of an acquired business’s internal control over financial reporting from the Company’s assessment of internal control for up to one year from the acquisition date. Vivasure represented a nominal amount of both the Company’s total net revenues in fiscal 2026 and total assets as of March 28, 2026. As such, the Company has excluded Vivasure from its annual assessment of internal control over financial reporting as of March 28, 2026.

Ernst & Young, LLP, an independent registered public accounting firm, has issued an attestation report on the effectiveness of the Company’s internal control over financial reporting. This report, in which they expressed an unqualified opinion, is included below.

Changes in Internal Controls

There have been no changes in the Company’s internal control over financial reporting during the quarter ended March 28, 2026 that have materially affected, or are likely to materially affect, the Company’s internal control over financial reporting.

During the second quarter of fiscal 2024, the Company implemented the first phase of a new global enterprise resource planning (“ERP”) system, which the Company expects will continue to be implemented in phases through fiscal 2027. The ERP will replace existing financial systems the Company has historically relied on. As each phase of the implementation occurs, the Company will reassess its processes and procedures, which may result in changes to its internal control over financial reporting.

To the Stockholders and the Board of Directors of Haemonetics Corporation

Opinion on Internal Control Over Financial Reporting

We have audited Haemonetics Corporation and subsidiaries’ internal control over financial reporting as of March 28, 2026, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Haemonetics Corporation and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of March 28, 2026, based on the COSO criteria.

As indicated in the accompanying Management’s Annual Report on Internal Control over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Vivasure Medical Limited, which is included in the 2026 consolidated financial statements of the Company and constituted 1% of total assets as of March 28, 2026 and 0% of net revenues for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of Vivasure Medical Limited.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2026 consolidated financial statements of the Company and our report dated May 20, 2026 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
