RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Our audit committee has appointed Deloitte & Touche LLP (“Deloitte”) as our independent registered public accounting firm to audit our consolidated financial statements for the fiscal year ending April 30, 2027. Deloitte has served as our independent registered public accounting firm since 2018. Representatives of Deloitte are expected to be present during the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our amended and restated bylaws nor law require stockholder ratification of the appointment of Deloitte as our independent registered public accounting firm. However, our audit committee is asking our stockholders to ratify its appointment of Deloitte because it values the views of our stockholders. If the stockholders fail to ratify the appointment, our audit committee may review the appointment of Deloitte as our independent registered public accounting firm but is under no obligation to review the appointment. Even if the appointment is ratified, our audit committee may, in its sole discretion, appoint different independent auditors at any time during the fiscal year if they determine that such a change would be in our best interests and the best interests of our stockholders.
