PROPOSAL THREE

RATIFICATION OF THE SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

As discussed in further detail in the Company’s proxy statement, the Audit Committee of the Board has retained Ernst & Young LLP
(“Ernst & Young”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025, and the Board is requesting that Stockholders ratify such selection. You should refer to the
Company’s proxy statement for further information on this proposal.

According to the Company’s proxy statement, the Company
expects representatives of Ernst & Young are to be present at the Annual Meeting with an opportunity to make a statement if they desire to do so and to be available to respond to appropriate questions.

According to the Company’s proxy statement, if the Stockholders fail to ratify the selection of Ernst & Young, the Audit
Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the
year
