Item 7.01

Regulation FD Disclosure.

On September 17, 2024, Neuronetics, Inc (“Neuronetics”) filed a joint proxy statement / management information circular (the “Joint Proxy Statement”) with the Securities and Exchange Commission (the “SEC”) concerning special shareholder and stockholder meetings of both Greenbrook TMS Inc. (the “Company”) and Neuronetics regarding the proposed acquisition of all of the Company’s issued and outstanding common shares by Neuronetics (the “Transaction”), among other matters. The Company continues to file certain periodic reports with the SEC pursuant to Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”); however, because the Company no longer has a class of securities registered under Section 12(b) of the Exchange Act, it is not subject to U.S. proxy rules and instead prepares its management information circular in accordance with Canadian corporate and securities law requirements.

The Joint Proxy Statement includes information about the Company and the proposed Transaction. Accordingly, a copy of the Joint Proxy Statement, which has been filed by the Company with the Canadian securities regulatory authorities, is furnished herewith as Exhibit 99.1. The information contained in Exhibit 99.1 is incorporated in this Item 7.01 by reference.

The information contained in this Current Report on Form 8-K under Item 7.01, including the attached Exhibit 99.1, is being furnished pursuant to Item 7.01 of Form 8-K and shall not be deemed to be “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section. The information contained in this Current Report on Form 8-K under Item 7.01 shall not be incorporated by reference into any filing under the Securities Act of 1933, as amended, or any filing under the Exchange Act, whether made before or after the date hereof, except as shall be expressly set forth by specific reference in such a filing.
