#### PROPOSAL NO. 2

### RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Audit Committee of the Board of Directors has selected BDO as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025 and has further directed management to submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. BDO has audited the Company’s financial statements since 2013. Representatives of BDO are expected to be present at 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 the Company’s Bylaws nor other governing documents or law require stockholder ratification of the selection of BDO as the Company’s independent registered public accounting firm. However, the Audit Committee of the Board is submitting the selection of BDO to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of different independent auditors at any time during the year if they determine such a change would be in the best interests of the Company and its stockholders.

The affirmative vote of the holders of a majority of the voting power of the shares of our Class A common stock and Class B common stock (voting together as a single class) present or represented by proxy at the Annual Meeting and entitled to vote on the proposal at the Annual Meeting will be required to ratify the selection of BDO. Abstentions have the same effect as an “Against” vote. Broker non-votes are not expected to result from this proposal.
