Item 5    Full Description of Material Change

5.1 - Full Description of Material Change

On February 1, 2021, Greenbrook announced that, in conjunction with its application to list its Common Shares on NASDAQ, the Company has completed the consolidation of its issued and outstanding Common Shares on the basis of one (1) post-consolidation Common Share for every five (5) pre-consolidation Common Shares.

On February 1, 2021, Greenbrook filed articles of amendment which implemented the Share Consolidation and the Company anticipates that its Common Shares will begin trading on a post-consolidation basis on the Toronto Stock exchange (“TSX”) at the market open on February 4, 2021 under its current trading symbol “GTMS”.

The Share Consolidation resulted in the number of issued and outstanding Common Shares being reduced from approximately 67.5 million to approximately 13.5 million, on a non-diluted basis. No fractional Common Shares were issued as a result of the Share Consolidation. Any fractional interest in Common Shares that would otherwise result from the Share Consolidation was rounded up to the next whole Common Share, if the fractional interest was equal to or greater than one-half of a Common Share, and was rounded down to the next whole Common Share if the fractional interest was less than one-half of a Common Share. The exercise price and number of Common Shares issuable upon the exercise of outstanding stock options, warrants or other convertible securities were proportionately adjusted to reflect the Share Consolidation in accordance with the terms of such securities.
