AVALON HOLDINGS CORP

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15 under the Securities Exchange Act of 1934 (the “Exchange Act”), Avalon’s management conducted an evaluation, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by the 2024 Annual Report. For purposes of the foregoing, the term disclosure controls and procedures means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s (“SEC”) rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Avalon’s disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives as outlined above. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that they believe that, as of December 31, 2024, our disclosure controls and procedures were effective at a reasonable assurance level.
