Management’s report on internal control over financial reporting

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)of the Exchange Act. The Company’s internal control over financial reporting is a process designed by management, with the participation of the Company’s President and Chief Executive Officer and Executive Vice President, Chief Financial Officer, and under the oversight of the Audit Committee of the Board of Directors, to provide reasonable assurance regarding the reliability of its financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) 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 (iii) 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.

Management, with the participation of the Company’s President and Chief Executive Officer and Executive Vice President, Chief Financial Officer, and under the oversight of the Audit Committee of the Board of Directors, assessed the effectiveness of the Company’s internal control over financial reporting as of March 31, 2025, based on the criteria set forth in “Internal Control—Integrated Framework (2013)”issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based upon this assessment, management concluded that, as of March 31, 2025, the Company’s internal control over financial reporting was effective.

The effectiveness of the Company’s internal control over financial reporting as of March 31, 2025 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Remediation of previously-identified material weakness

As previously reported, management identified a material weakness as of March 31, 2024 in the Company’s internal control over financial reporting related to IT general controls in Europe for systems supporting the Company’s accounting and financial reporting processes. Specifically, the Company did not appropriately restrict access to certain systems. As a result, automated process-level controls and manual controls that are dependent upon the accuracy and completeness of information derived from those IT systems were also ineffective since they could have been adversely impacted. The material weakness resulted from an insufficient number of trained resources with the IT expertise necessary to appropriately assess and be accountable for IT-related risks or effectively design, implement, and operate controls to monitor and restrict access to systems that support the Company’s accounting and financial reporting processes.

Management has completed the following remediation steps during fiscal 2025 and has concluded that the material weakness has been remediated as of March 31, 2025.

Changes in internal control over financial reporting

During the fourth quarter of fiscal 2025, management completed the remediation steps for the previously-identified material weakness, as described above. There have been no other changes in internal control over financial reporting during the fourth quarter of fiscal 2025 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
