Item 5.07. Submission of Matters to a Vote of Security Holders.

On March 25, 2026, Greenlane Holdings, Inc. (the “Company”) held a Special Meeting of Stockholders (the “Special Meeting”). At the Special Meeting, a total of 2,074,598 shares of the Company’s Class A common stock, $0.01 par value per share (the “Common Stock”), or approximately 41.2% of the 5,039,563 shares of Common Stock, issued and outstanding as of the close of business on February 25, 2026, the record date for the Special Meeting, were represented virtually or by proxy.

At the Special Meeting, the Company’s stockholders considered two proposals, each of which is described in more detail in the Company’s definitive proxy statement filed with the Securities and Exchange Commission on February 26, 2026.

Set forth below is a brief description of each proposal voted upon at the Special Meeting and the voting results with respect to each proposal.

Proposal No. 1: To approve any amendment to the Company’s Amended and Restated Certificate of Incorporation to effect a reverse stock split of the Common Stock, within a range of 1-for-5 to 1-for-15 (or any number in between), without reducing the authorized number of shares of the Common Stock, and the filing of a final amendment with the ratio within such range to be determined in the sole discretion of the Board of Directors of the Company at any time on or before April 30, 2026, without further approval or authorization of the Company’s stockholders (the “Reverse Stock Split Proposal”).

Proposal No. 2: To consider and vote upon an adjournment of the Special Meeting, if necessary, to solicit additional proxies if there are not sufficient votes in favor of the Reverse Stock Split Proposal.

An adjournment of the Special Meeting was not necessary because there were sufficient votes in favor of the Reverse Stock Split Proposal.
