Board Committees

Audit Committee

On February 14, 2024, the board of directors (the “Board”) of Vast Renewables Limited (the “Company”) appointed Peter Botten and William Restrepo as members of the audit committee of the Board (the “Audit Committee”) and John Yearwood as chairperson of the Audit Committee. Concurrently with the appointments of Mr. Botten and Mr. Restrepo to the Audit Committee, Colleen Calhoun and Colin Richardson stepped down from the Audit Committee. The changes in the composition of the Audit Committee were the result of the Board’s decision to revisit each committee’s membership following the appointment of Mr. Botten and Thomas Quinn to the Board in January and were not related to any disagreement by Ms. Calhoun or Mr. Richardson with the Company on any matter relating to the Company’s operations, policies or practices.

The Board has determined that Mr. Botten and Mr. Yearwood each meet the independent director standard under Nasdaq Listing Rules and under Rule 10A-3(b)(1) of the Security Exchange Act of 1934, as amended, but Mr. Restrepo does not. The Company has one year from the date of its listing on Nasdaq to have its Audit Committee be comprised solely of independent members. The Company intends to identify one additional independent director to serve on the Audit Committee by such deadline, at which time Mr. Restrepo will resign from the Audit Committee. Each member of the Audit Committee meets the requirements for financial literacy under the applicable rules and regulations of the SEC and the Nasdaq Listing Rules. The Board has determined that Mr. Yearwood is an audit committee financial expert as defined by the SEC rules and is financially sophisticated as defined by the Nasdaq Listing Rules.

Compensation Committee

On February 14, 2024, the Board appointed Mr. Botten, Mr. Quinn and Mr. Yearwood to the compensation committee of the Board (the “Compensation Committee”). Mr. Restrepo remains the chairperson of the Compensation Committee. Concurrently with the appointments of Mr. Botten, Mr. Quinn and Mr. Yearwood, Mr. Richardson stepped down from the Compensation Committee. The changes in the composition of the Compensation Committee were the result of the Board’s decision to revisit each committee’s membership following the appointment of Mr. Botten and Mr. Quinn to the Board in January and were not related to any disagreement by Mr. Richardson with the Company on any matter relating to the Company’s operations, policies or practices.

As a foreign private issuer, the Company is permitted, and has elected, to follow Australian practice, which does not require a compensation committee composed solely of independent directors.

Nominating and Corporate Governance Committee

On February 14, 2024, the Board appointed Mr. Botten and Mr. Yearwood to the nominating and corporate governance committee of the Board (the “Nominating and Corporate Governance Committee”). Ms. Calhoun remains the chairperson of the Nominating and Corporate Governance Committee and Mr. Richardson remains a member of the Nominating and Corporate Governance Committee. Concurrently with the appointments of Mr. Botten and Mr. Yearwood to the Nominating and Corporate Governance Committee, Mr. Restrepo stepped down from the Nominating and Corporate Governance Committee. The changes in the composition of the Nominating and Corporate Governance Committee were the result of the Board’s decision to revisit each committee’s membership following the appointment of Mr. Botten and Mr. Quinn to the Board in January and were not related to any disagreement by Mr. Restrepo with the Company on any matter relating to the Company’s operations, policies or practices.

Projects Committee

Furthermore, on February 14, 2024, the Board (i) established the projects committee of the Board (the “Projects Committee”), which is responsible for the oversight of Vast Solar 1, the Company’s 30 MW reference concentrated solar power plant located in Port Augusta, and Solar Methanol 1, the Company’s 20 ton per day solar methanol demonstration facility, and (ii) appointed Mr. Botten, Ms. Calhoun and Mr. Richardson as members of the Projects Committee and Mr. Quinn as chairperson of the Projects Committee.
