orum is achieved, a plurality of votes cast is necessary for the election of directors (Proposal 1). As to all other matters, the affirmative vote of a majority of votes cast is necessary for the approval of such matters.

Some of our shareholders hold their shares through a stockbroker, bank, or other nominee rather than directly in their own name. Those shareholders are considered the beneficial owner of shares held in street name, and these materials are being forwarded to you by your broker, bank or nominee, which is considered the shareholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or nominee how to vote and are also invited to attend the Annual Meeting. However, because you are not the shareholder of record, you may not vote these shares in person at the Annual Meeting unless you obtain a signed proxy from the shareholder of record giving you the right to vote the shares.

A broker non-vote occurs when a broker holding shares for a beneficial owner does not vote on a particular proposal because the broker does not have discretionary voting power with respect to that item and has not received voting instructions from the beneficial owner. Your broker has discretionary authority to vote your shares with respect to ratification of the appointment of Plante & Moran, PLLC (“Plante”) as our independent registered public accounting firm (Proposal 2). However, in the absence of specific instructions from you, your broker does not have discretionary authority to vote your shares with respect to the election of directors to the Board of Directors (Proposal 1). A broker non-vote does not count as a vote in favor of or against a particular proposal for which the broker has no discretionary voting authority.

In addition, if a shareholder abstains from voting on a particular proposal presented for approval at the Annual Meeting, the abstention does not count as a vote in favor of or against the proposal.

At this year’s Annual Meeting, you will elect four (4) directors to serve for a term of three years commencing on the date of the Annual Meeting and continuing until the 2028 annual meeting of shareholders of the Company or until their respective
