Avalon Advanced Materials completes common share consolidation

Toronto, Ontario--(Newsfile Corp. - July 8, 2026) - Avalon Advanced Materials Inc.  (TSX: AVL) (OTCQB: AVLNF) ("Avalon" or the "Company") announces that it has completed, effective July 8, 2026 (the "Effective Date"), a consolidation of the common shares in the capital of the Company (the "Common Shares") outstanding on the basis of one hundred eighty (180) pre-consolidation Common Shares for every one (1) post-consolidation Common Share (the "Consolidation"). The Consolidation was previously approved by the Company's shareholders at its special meeting of shareholders held on June 29, 2026 (the "Meeting"), and the one hundred eighty (180) to one (1) consolidation ratio approved by the board of directors of the Company is within the previously disclosed range of ratios authorized by the shareholders at the Meeting. The Consolidation is intended to provide the Company with a more conventional capital structure and support its ongoing evaluation of broader capital markets opportunities, including a potential future U.S. exchange listing.

Notice of the Consolidation has been provided to the Toronto Stock Exchange ("TSX"). The Common Shares will continue to be listed on the TSX under the symbol "AVL" and the OTCQB® Venture Market ("OTCQB") under the symbol "AVLNF" except that for approximately twenty (20) trading days after the implementation of the Consolidation, the Company's symbol on the OTCQB may display as AVLNFD. The Common Shares are expected to begin trading on a post-Consolidation basis on the TSX on or about July 13, 2026.

Following the Consolidation, the new CUSIP number for the Common Shares is 05337L502 and the new ISIN for the Common Shares is CA05337L5027. As a result of the Consolidation, the 835,628,796 Common Shares that were issued and outstanding prior to the Consolidation have been reduced to approximately 4,642,382 Common Shares (disregarding the treatment of any resulting fractional Common Shares). Each shareholder's percentage ownership in the Company and proportional voting power remains unchanged after the Consolidation, except for minor changes and adjustments resulting from the treatment of any resulting fractional Common Shares.

The Company will not be issuing fractional post-Consolidation Common Shares. Where the Consolidation would otherwise result in a shareholder being entitled to a fractional Common Share, the number of post-Consolidation Common Shares issued to such shareholder will be rounded down to the nearest whole number of Common Shares and such shareholder will be entitled to a cash payment in lieu of the fractional interest to which the shareholder would otherwise be entitled equal to such fractional interest (which for greater certainty will be equal to the number of pre-consolidation Common Shares that would otherwise result in the fractional post-consolidation Common Share) multiplied by the closing price of the Common Shares, as reported by the TSX, on the last trading day prior to the effective date of the Consolidation. The closing price of the Common Shares on the TSX on July 7, 2026, the last trading day prior to the Consolidation, was $0.045.

Shareholders that are entitled to a cash payment of $5.00 or more will be, after submitting any physical share certificates they hold, a letter of transmittal and any other documentation required by the Exchange Agent (as defined below) to the Exchange Agent, automatically mailed a cheque by the Exchange Agent. Shareholders that are entitled to a cash payment of less than $5.00 may contact the Exchange Agent at TSX Trust Company, Suite 301, 100 Adelaide Street West, Toronto, ON M5H 4H1, telephone number (416) 342-1091 or toll-free in North America at 1 (866) 600-5869 for more information on how to obtain their cash payment. The Company's transfer agent, TSX Trust Company (the "Exchange Agent"), will act as the exchange agent for the Consolidation.

In connection with the Consolidation, the Exchange Agent has sent a letter of transmittal to registered shareholders holding their Common Shares in certificated form to exchange their old share certificates for direct registration statement(s) or share certificate(s), in accordance with the instructions provided in the letter of transmittal. Registered shareholders will be able to obtain additional copies of the letter of transmittal through the Exchange Agent. Until surrendered, each certificate representing pre-Consolidation Common Shares will represent the number of whole post-Consolidation Common Shares to which the holder is entitled as a result of the Consolidation.

Shareholders that hold their Common Shares via physical share certificates will need to submit their share certificates, a letter of transmittal and any other documents required by the Exchange Agent to the Exchange Agent prior to the third anniversary of the Effective Date in order to receive any cash payment to which they are entitled. Registered holders holding their Common Shares by way of a Direct Registration System Advice/Statement, and non-registered beneficial holders holding their Common Shares through intermediaries (securities brokers, dealers, banks, financial institutions, etc.) will not need to complete a letter of transmittal. Non-registered beneficial holders holding their Common Shares through an intermediary should note that such intermediaries may have specific procedures for processing the Consolidation.

Shareholders holding their Common Shares through such an intermediary and who have any questions in this regard are encouraged to contact their intermediary. The exercise or conversion price and the number of Common Shares issuable under any of the Company's outstanding convertible securities will be proportionately adjusted to reflect the Consolidation in accordance with the respective terms thereof.
