FIRST QUARTER 2021 OPERATIONAL AND FINANCIAL HIGHLIGHTS

Quarterly revenue increased by 15% to $13.1 million as compared to the first quarter of 2021 ("Q1 2021"). Treatment volumes increased by 13% to 59,067 as compared to Q1 2021.
The COVID-19 omicronvariant, paired with typical seasonal factors,affected quarter-over-quarter results. Revenue decreased by 7% as compared to the fourth quarter of 2021 ("Q4 2021"), while treatments decreased by 4% as compared to Q4 2021.
New patient starts increased by 15% to a record 1,817 as compared to Q1 2021, and 9% as compared to Q4 2021, showing strong forward momentum into the second quarter of 2022.
Entity-wide regional operating loss decreased by 30% to $1.0 million as compared to $1.5 million in Q1 2021.
The Company continued the roll-out of its Spravato® (esketamine nasal spray) offering at select TMS treatment centers ("TMS Centers"). As at March 31, 2022, the Company expanded its offering of Spravato® to 23 TMS Centers across the United States, building on the long-term business plan of utilizing our TMS Centers as platforms for the delivery of innovative treatments to patients suffering from Major Depressive Disorder and other mental health disorders.

Bill Leonard, President and Chief Executive Officer of Greenbrook commented:

"Despite the impact of the COVID-19 omicron variant early in the quarter, we continued to see resilient growth in both revenue and new patient starts, with the latter producing a record result during Q1 2022. We are very excited about the promising prospects of the continued roll-out of our Spravato® program to more of our active TMS Centers which we believe will enhance profit margins by optimizing the utilization of our current TMS Centers. This builds on our long-term strategy of utilizing our growing network of TMS Centers and affiliated physicians as a services platform to deliver innovative treatments to patients suffering from mental health disorders. We believe that record forward-looking indicators late in the quarter will provide strong momentum into the second quarter and we believe this will position us better than ever to serve the unmet need for mental health support across the United States."
