HYZN 2023 Proxy Statement

Board Committees The Board established an audit committee, a compensation committee, an ESG committee, and a nominating and corporate governance committee. The Board adopted charters for the audit, compensation, and nominating and corporate governance committees, which charters comply with the applicable requirements of Nasdaq rules. We intend to comply with future requirements to the extent they will be applicable to us. Copies of the charters for the audit committee, the compensation committee and the nominating and corporate governance committee are available on the investor relations portion of our website at www.hyzonmotors.com. Each committee has the composition and responsibilities described below. Audit Committee Our Audit Committee consists of Ivy Brown, Dennis Edwards, Elaine Wong, and Matthew Foulston, who just joined the Board in July 2023. Ki Deok (“KD”) Park was previously on the Audit Committee as a financial expert prior to his resignation effective January 31, 2023. The Board determined that each member of the Audit Committee satisfies the independence requirements of the Nasdaq listing rules and Rule 10A-3 under the Exchange Act. Each member of the Audit Committee can read and understand fundamental financial statements in accordance with Nasdaq audit committee requirements. In arriving at this determination, the Board examined each Audit Committee member’s scope of experience and the nature of their prior and/or current employment. During the 2022 fiscal year, our Audit Committee held eleven meetings. Matthew Foulston serves as the chair of the Audit Committee, having replaced Ivy Brown in July 2023. The Board determined that Elaine Wong qualifies as an audit committee financial expert within the meaning of SEC regulations and meets the financial sophistication requirements of the Nasdaq listing rules. In making this determination, the Board considered Ms. Wong’s formal education and previous experience in financial roles. Both our independent registered public accounting firm and management periodically meet privately with our Audit Committee. The functions of the Audit Committee include, among other things: • evaluating the performance, independence and qualifications of our independent auditors and determining their compensation and whether to retain our existing independent auditors or engage new independent auditors; • reviewing our financial reporting processes and disclosure controls; • reviewing and approving the engagement of our independent auditors to perform audit services and any permissible non-audit services; • reviewing the adequacy and effectiveness of our internal control policies and procedures, including the agenda, responsibilities, priorities, plan and staffing of our internal audit function; • reviewing with the independent auditors the annual audit plan, including the scope of audit activities and all critical accounting policies and estimates to be used by us; • obtaining and reviewing at least annually a report by our independent auditors describing the independent auditors’ internal quality control procedures and any material issues raised by the most recent internal quality-control review; • monitoring the rotation of partners of our independent auditors on our engagement team as required by law; • prior to engagement of any independent auditor, and at least annually thereafter, reviewing relationships that may reasonably be thought to bear on their independence, and assessing and otherwise taking the appropriate action to oversee the independence of our independent auditor; • preparing any report of the Audit Committee required by the rules and regulations of the SEC for inclusion in our annual proxy statement and reviewing our annual and quarterly financial statements and reports, including the disclosures contained in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and discussing the statements and reports with our independent auditors and management; • reviewing with our independent auditors and management significant issues that arise regarding accounting principles and financial statement presentation and matters concerning the scope, adequacy, and effectiveness of our financial controls and critical accounting policies and estimates; • reviewing with management and our auditors any earnings announcements and other public announcements regarding material developments; • establishing procedures for the receipt, retention and treatment of complaints received by us regarding accounting, internal accounting controls or auditing matters, and for the confidential, anonymous submission by our employees or any provider of accounting-related services of concerns regarding questionable accounting and auditing matters and review of submissions and the treatment of any such complaints; 20 | Hyzon Motors 2023 Proxy Statement
