Neuronetics, Inc. (NASDAQ:STIM) ("Neuronetics") and Greenbrook TMS Inc. (OTC:GBNHF) ("Greenbrook") today announced that the Ontario Superior Court of Justice (Commercial List) (the "Court") has granted an interim order (the "Interim Order") in connection with the previously announced statutory plan of arrangement under section 182 of the Business Corporations Act (Ontario) (the "Plan of Arrangement"), pursuant to which, subject to the satisfaction or waiver of all applicable conditions precedent, Neuronetics will acquire all of the issued and outstanding common shares of Greenbrook ("Greenbrook Shares") in an all-stock transaction (the "Arrangement"). The Interim Order authorizes the calling and holding of a special meeting (the "Greenbrook Special Meeting") of holders of Greenbrook Shares ("Greenbrook Shareholders"), the granting of dissent rights to registered Greenbrook Shareholders and other matters relating to the conduct of the Greenbrook Special Meeting.

Subject to the terms of the Plan of Arrangement, each Greenbrook Share outstanding immediately prior to the effective time of the Arrangement (other than all Greenbrook Shares held by Greenbrook Shareholders who have validly exercised rights of dissent in respect of the Arrangement) is expected to be exchanged for 0.01149 of a share of Neuronetics common stock ("Neuronetics Shares") at the closing of the Arrangement, subject to adjustment for any interim funding by Madryn Asset Management, LP or its affiliates ("Madryn") and other customary adjustments prior to the closing of the Arrangement. Upon completion of the Arrangement, the pre-Arrangement holders of Neuronetics Shares ("Neuronetics Stockholders") and Greenbrook Shareholders are expected to own approximately 57% and 43% of the combined company, respectively, on a fully diluted basis.

On the unanimous recommendation of a special committee of the board of directors of Greenbrook (the "Greenbrook Board") consisting entirely of independent directors, the Greenbrook Board unanimously determined that the Arrangement is fair to Greenbrook Shareholders (other than Madryn) and in the best interests of Greenbrook. The Greenbrook Board unanimously recommends that the Greenbrook Shareholders vote in favour of the resolution relating to the Arrangement at the Greenbrook Special Meeting.

The board of directors of Neuronetics (the "Neuronetics Board") unanimously determined that the Arrangement is in the best interests of Neuronetics. The Neuronetics Board unanimously recommends that Neuronetics Stockholders vote in favor of the resolutions relating to the Arrangement at the special meeting of Neuronetics Stockholders (the "Neuronetics Special Meeting").
