Systemwide Pro Forma Revenue and Adjusted EBITDA are Non-GAAP measures. See "Note Regarding Non-GAAP Measures, Reconciliation, and Discussion".

"Our business inflected during the first quarter of 2022 as a result of the investments and efficiencies we made over the last 18 months to meet our long-term strategic goals," said Leo Gontmakher, Chief Executive Officer of 4Front. "We now have a fully-capitalized infrastructure in place to drive robust growth through this year and well into the future. Our thesis of providing consistent, low-cost production at scale continues to play out as designed, with the operational achievements from 2021 continuing to provide a solid foundation for the expected growth of our production and sales."

"In California, we were proud to announce the acquisition of Island at the end of March and its subsequent closing in April. The Island brand and their seasoned management team are perfect complements to the 4Front model, and since closing the transaction we have fully integrated Island into our production and distribution channels. The scale of our Commerce operations enables us to buy similarly successful, attractive brands and manufacture them at considerably lower cost, producing strong margins which fall right to our bottom line. We look forward to announcing more exciting developments in California over the coming months."

"Our retail operations are showing solid performance, with increasing customer counts despite some expected pricing headwinds. Additionally, our cultivation and manufacturing processes and facilities are now fully optimized for the large-scale production of high-quality, low-cost products. The acquisition of NECC and its state-of-the-art facility, the best we have ever seen, has contributed to improvements not only in Massachusetts, but across our platform as we further implement their practices into our own process. The resulting high-quality flower has enabled increased sales of our house brands and further penetration into wholesale markets."

"We're excited to set up our next stage of growth in Illinois, with the first phase of our latest facility in Matteson expected to be completed in six months and ahead of schedule. I am confident that with the completion of the Matteson facility on the near horizon, and a fully operational Commerce facility showing strong sales momentum, we are fully prepared for our next stage of growth as a business."

"Our corporate, operational, and commercial decisions are driven by our commitment to supplying our customers with low-cost, high-quality cannabis and consumer packaged goods at scale, all while maximizing shareholder value. I am more confident than ever that we have one of the most knowledgeable and experienced teams to successfully outperform in this industry as it continues to mature. We look forward to reporting our continued success as we progress through a very active Q2."

In January 2022, the Company completed its acquisition of NECC, following approval by the Massachusetts Cannabis Control Commission. NECC's state-of-the art 55,000 square foot cultivation and production facility significantly bolsters 4Front's strategic position in the Massachusetts market and expands the Company's institutional knowledge of lighting, airflow, and fertigation techniques. The acquisition firmly establishes the Company's presence as a leading operator in the region and allows for the expanded distribution of our products in the wholesale market, supporting our goal of being the premier low-cost finished goods wholesaler in Massachusetts.

In March 2022, 4Front signed a definitive agreement to acquire Island Cannabis Co., a leading California producer of pre-roll, flower, and concentrate products, and the first California brand to join 4Front's platform. Following its subsequent completion in April 2022, the acquisition adds premium flower to the 4Front product suite, and significant talent to the Company's bench. Importantly to the Company's long-term California strategy, Island's management team brings deep operational experience in the local market to 4Front. Following the completion of the acquisition, 4Front has appointed former Island executives to its management team, including Ray Landgraf as President of California Operations, and Brandon Mills as Executive Vice President.

Production at the Company's 170,000 square foot state-of-the-art production facility in Commerce, California continues to ramp, and after six months of operations, 4Front is more confident than ever that it is uniquely positioned to be truly disruptive in a California market that is ripe for consolidation and subsequent streamlining of cost efficiencies. The Commerce facility allows the Company to acquire brands and manufacture them significantly cheaper and more profitably, seamlessly integrating into 4Front's production lines in a matter of weeks - a key differentiator in its California growth strategy.

Construction of 4Front's cultivation and production facility in Matteson, Illinois remains ahead of schedule and on track to be completed in Q4 2022. The 250,000 square foot initial phase is expected to begin operations in Q1 2023 and will be a key growth factor moving forward as the Company expands its wholesale business and retail footprint in Illinois. Consumer and wholesale demand continues to increase in the state, and with only two of its allowable ten dispensaries open so far, the Company anticipates substantial room for growth as it expands both its retail footprint and its wholesale presence in the medium-term.

Systemwide Pro Forma Revenue for Q1 2022 was $32.4 million, up 7% from Q1 2021. GAAP revenue for Q1 2022 was $26.1 million, up 13% from Q1 2021. The Company reiterates its belief that wholesale growth in both Massachusetts and Illinois is poised to strengthen over the year as additional retail comes on-line in those underserved states.

Adjusted EBITDA for Q1 2022 was $9.0 million, up 53% from Q1 2021, representing an Adjusted EBITDA margin of 28%. Stepwise growth of Adjusted EBITDA and margin is expected to continue through 2023 as the Company's operations drive increased production, higher sales volumes, and additional retail opportunities.

As of March 31, 2022, the Company had $8.6 million of cash and $48.7 million of related-party long-term debt not due until May 2024. As of today the Company has 636,636,686 subordinate voting shares outstanding.
