At the Virtual Meeting — Shares held in your name as the stockholder of record may be voted electronically at the Annual Meeting by visiting www.proxydocs.com/HYZN and using the control number included on your proxy materials. If you have already voted previously by Internet or telephone, there is no need to vote again at the Annual Meeting unless you wish to revoke and change your vote. Shares held beneficially in street name may be voted electronically at the Annual Meeting only if you obtain a legal proxy from the broker, bank, or nominee that holds your shares giving you the right to vote the shares. Even if you plan to attend the Annual Meeting via live audio webcast, we recommend that you also submit your proxy or voting instructions or vote by Internet, telephone, or mail prior to the meeting so that your vote will be counted if you later decide not to attend or vote at the meeting. Can I change my vote or revoke my proxy? You may change your vote or revoke your proxy at any time prior to the vote at the Annual Meeting. If you submitted your proxy by Internet or telephone, you may change your vote or revoke your proxy with a later Internet or telephone proxy. If you are a stockholder of record and submitted your proxy by mail, you must file with the Secretary of the Company a written notice of revocation or deliver, prior to the vote at the Annual Meeting, a valid, later-dated proxy. Attendance at the Annual Meeting will not have the effect of revoking a proxy unless you give written notice of revocation to the Secretary before the proxy is exercised or you vote at the Annual Meeting. If you are a beneficial owner of shares held in street name and you wish to change or revoke your vote, you must obtain a legal proxy through your broker, bank or nominee and present it to Continental at least two weeks in advance of the Annual Meeting. Please consult the voting instructions or contact your broker, bank or nominee. How are votes counted? For Proposal 1, the election of directors, you may vote “FOR” the nominees, or your vote may be “WITHHELD” with respect to any or all the nominees. “WITHHELD” votes will not affect the outcome. For Proposal 2, the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the year ending December 31, 2023, you may vote “FOR,” vote “AGAINST”, or “ABSTAIN.” An abstention has the same effect as a vote “AGAINST” this proposal.

If you hold shares beneficially in street name and do not provide your broker or nominee with voting instructions, your shares may constitute “broker non-votes.” Generally, broker non-votes occur on a matter when a broker or nominee does not have discretionary authority to vote on that matter without instructions from the beneficial owner and instructions are not given. Discretionary items are proposals considered “routine” under the rules of The NASDAQ Stock Market, LLC (“Nasdaq”), such as the ratification of the appointment of our independent auditors, and therefore, broker non-votes are not expected to exist with respect to this proposal. Proposal 1, the election of the three nominee directors, is considered a “non-routine” item for which brokers and nominees do not have discretionary power to vote and, therefore, broker non-votes may exist with respect to the “non-routine” proposal.
