PROPOSAL 4: RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR 2025

The Audit Committee is responsible for the appointment, compensation (including final approval of audit and other fees), retention and oversight of the independent registered public accounting firm that audits our financial statements and our internal control over financial reporting. The Audit Committee annually reviews Ernst & Young’s independence and performance in deciding whether to retain Ernst & Young or engage an alternative independent auditor. As part of this review, the Audit Committee, among other factors, considers the following:

| • | Ernst & Young’s historical and annual performance including input from Audit Committee members, other independent directors and our management. |

| • | Ernst & Young’s expertise and qualifications in serving as independent auditor for our different business operations. |

| • | A review of Ernst & Young’s known legal risks and any significant legal or regulatory proceedings in which it is involved. |

| • | Other information on audit quality and performance including recent PCAOB reports on Ernst & Young and its peer firms. |

| • | Periodic rotation of the lead partner and engagement quality review partner and their industry experience and expertise most relevant to the Company’s business operations. |

| • | Ernst & Young’s conclusion that they are independent with respect to serving as our independent auditor. |

In addition to Ernst & Young’s conclusion that they are independent, the Audit Committee believes that Ernst & Young is independent and that there are controls and processes that help ensure such independence including the following: (a) Audit Committee oversight of Ernst & Young includes at

least four private meetings each year and an additional four private meetings with the Audit Committee Chair prior to each quarterly Audit Committee meeting; (b) Audit Committee interaction with and review of the industry and other qualifications of the lead partner and of the engagement quality review partner; (c) oversight of non-audit services that require preapproval by the Audit Committee precludes certain non-audit services and determines that Ernst & Young is an appropriate service provider; (d) discussions with Ernst & Young regarding their
