CURALEAF CONFIRMS EFFECTIVE DATE OF REVERSE STOCK SPLIT

Curaleaf Holdings Inc. today confirmed that the previously announced 1-for-3 reverse stock split of its subordinate voting shares will become effective on June 5, 2026.

Upon completion of the reverse stock split, the company's subordinate voting shares will continue to trade on the Toronto Stock Exchange under the symbol CURA and under the new Cusip No. 23126M300.

The company will not be issuing fractional postreverse stock split subordinate voting shares in connection with the reverse stock split. Where the reverse stock split would otherwise result in a shareholder being entitled to a fractional subordinate voting share, the number of postreverse stock split subordinate voting shares issued to such holder of subordinate voting shares shall be rounded up or down to the nearest whole number of subordinate voting shares.

The company currently has 698,731,895 subordinate voting shares outstanding and, assuming no additional subordinate voting shares are issued prior to the reverse stock split, the reverse stock split will reduce the issued and outstanding subordinate voting shares to approximately 232,910,632 subordinate voting shares.

A letter of transmittal with respect to the reverse stock split has been mailed to registered shareholders of the company. All registered shareholders will be required to deliver their certificate(s) or direct registration advice(s) representing prereverse stock split subordinate voting shares along with a completed letter of transmittal to the company's transfer agent, Odyssey Trust Company, in accordance with the instructions provided in the letter of transmittal. Additional copies of the letter of transmittal can be obtained through Odyssey. All shareholders who submit a duly completed letter of transmittal along with their prereverse stock split subordinate voting shares certificate(s) or direct registration advice(s) to Odyssey will receive a postreverse stock split subordinate voting share certificate or direct registration advice. Shareholders who hold their subordinate voting shares through a broker or other intermediary and do not have subordinate voting shares registered in their name will not need to complete a letter of transmittal. Beneficial shareholders who have questions regarding how their subordinate voting shares will be processed in connection with the reverse stock split should contact their intermediaries.

As part of the reverse stock split, the company will also effect a concurrent consolidation of its multiple voting shares upon the same one-for-three consolidation ratio so as to maintain and preserve the relative rights of the holders of the shares of each class of shares of the company.
