GREENBROOK TMS RAISES US$3.0 MILLION IN DEBT FINANCING

TORONTO, Aug. 1, 2023 /PRNewswire/ - Greenbrook TMS Inc. (NASDAQ: GBNH) ("Greenbrook" or the "Company") today announced that it has received US$2.0 million in debt financing under its Credit Facility (as defined below) agented by Madryn Fund Administration, LLC ("Madryn"), and US$1.0 million in debt financing from Greybrook Health Inc. ("Greybrook Health"), one of the Company's existing significant shareholders (collectively, the "Debt Financing"), in order to manage the company's current liquidity requirements.

The Company announces that it has entered into an amendment (the "Credit Facility Amendment") to its previously-announced credit facility with Madryn (the "Credit Facility"), whereby certain affiliates of Madryn have extended an additional tranche of debt financing to the Company in an aggregate principal amount of US$2.0 million, which was fully-funded at closing (the "New Loan"). The terms and conditions of the New Loan are consistent with the terms and conditions of the Company's existing aggregate US$61 million loan (plus fees and accrued interest) under the Credit Facility (the "Existing Loan" and, together with the New Loan, the "Madryn Loans") in all material respects.

The New Loan also provides Madryn with the option to convert up to approximately US$182,000 of the outstanding principal amount of the New Loan into common shares of the Company ("Common Shares") at a conversion price per share equal to US$1.90 (the "Conversion Price"), subject to customary anti-dilution adjustments (the "Conversion Instrument"). This conversion feature corresponds to the conversion provisions for its Existing Loan, which provide Madryn with the option to convert a portion of the outstanding principal amount of the Existing Loan into Common Shares at the Conversion Price.

The Credit Facility Amendment also provides that the entire amount of the interest payment due on June 30, 2023, which was previously deferred under prior amendments to the Credit Facility, will be paid in-kind and be added to the outstanding principal amount of the Existing Loan. The Credit Facility Amendment also extends the period during which the Company's minimum liquidity covenant is reduced from US$3,000,000 to US$300,000 to August 15, 2023.

The Company also announces that, alongside the New Loan, it has entered into a note purchase agreement (the "Note Purchase Agreement") with Greybrook Health whereby the Company has issued and sold US$1.0 million aggregate principal amount of an unsecured note (the "Note") to Greybrook Health (the "Note Purchase"). The Note bears interest at a rate consistent with the Credit Facility and matures on September 30, 2027. The Note is subordinated to the Madryn Loans.

As additional consideration for the Note Purchase, Greenbrook has issued 250,000 common share purchase warrants to Greybrook Health (the "Warrants"). Each Warrant will be exercisable for one Common Share at an exercise price equal to (a) if the Common Shares are listed on the Nasdaq or any other trading market at the time of exercise, 85.0% of the volume-weighted average trading price of the Common Shares on the Nasdaq (or, if not listed on Nasdaq, then such other trading market on which the Common Shares are principally traded, based upon daily share volume) for the five trading days immediately preceding the exercise date, or (b) if the Common Shares are not listed on any trading market at the time of exercise, a per share price based on fair market value, as determined by the board of directors of the Company, in each case subject to customary anti-dilution adjustments. The Warrants will expire five years from the date of issuance.

The proceeds of the New Loan, the Note, the Conversion Instrument and the Warrants (collectively, together with the underlying Common Shares, the "Securities") are expected to be used by the Company for general corporate and working capital purposes. The Company is also currently considering additional near-term financing options to address its future liquidity needs.
