4Front Ventures is built upon battle-tested operating capabilities, experienced and aligned leadership, a strategic, multi-state asset base, and a commitment to being a magnet for talent.

VANCOUVER, BC, and PHOENIX, AZ - TheNewswire - July 31, 2019 - Cannex Capital Holdings Inc. (CSE:CNNX; OTCQX:CNXXF) ("Cannex") and 4Front Holdings LLC ("4Front") announce the closing of their merger and the creation of 4Front Ventures Corp. ("4Front Ventures").

-New Ticker Symbol - FFNT. 4Front Ventures will trade on the Canadian Securities Exchange ("CSE") under the new ticker "FFNT," beginning on Tues., Aug. 6, 2019. -To allow for current Cannex's shareholders brokerage records to update with the new FFNT shares, CNNX will not trade on Aug. 1 and 2, 2019. This updating is outside of Cannex's or 4Front Ventures' control. If shareholders' records are not updated by Aug. 6, they should contact their brokerage for more information. -As a newly created issuer, 4Front Ventures will immediately pursue an OTC Markets quotation, and will advise as updates on the process are available. During this time, it is anticipated that Cannex's OTCQX quotation (OTCQX: CNXXF) will be withdrawn until 4Front Ventures' registration is complete. -A conference call for investors will be held by Josh Rosen, co-founder and CEO of 4Front, and continuing CEO of 4Front Ventures, on Fri., Aug. 2, at 11 a.m. ET (details below).

The CSE has confirmed that 4Front Ventures, which now owns and operates the assets of Cannex and 4Front, will begin trading on Aug. 6, 2019, under the ticker symbol "FFNT," and will issue a confirmatory bulletin shortly. A company conference call hosted by Josh Rosen, co-founder and CEO of 4Front, who will continue to serve as CEO of 4Front Ventures, will be held on Fri., Aug. 2, at 11 a.m. ET (details below).

The merger combines Cannex's large-scale cultivation and manufacturing capabilities, as demonstrated by its portfolio of successful product brands, with 4Front's existing strategic asset base and its long-standing retail, regulatory, and growth capabilities. The result is a cannabis company built for the long haul.

"This is a marriage of complementary teams and skill sets," Rosen said. "The 4Front team traces its retail heritage to Harborside, an industry pioneer and one of the most well-respected cannabis dispensaries in the country, while the Cannex leadership team has done a remarkable job developing production capabilities that have enabled its brands to sustain market leadership in a highly competitive Washington State market."

Rosen added: "With this merger complete, 4Front Ventures now has a tremendous base from which to rapidly expand within new and existing markets by applying what we've learned in the most competitive market in the country. While we have been diligent at growing our footprint when it made sense, we've invested as much time and effort into building a team and systems that are both necessary and able to successfully scale operations. As we have seen in the market up to today, acquiring assets is easy; it's operating them that's hard."

Additional Management Commentary

Anthony Dutton, CEO of Cannex and becoming Managing Partner, 4Front International for 4Front Ventures:

"In 4Front, Cannex has found a company that shares our belief that operations matter. Both companies have invested heavily in operations and building systems that will scale to new and expanding markets. Applying those capabilities and executing on the growth opportunities ahead of us will go far in optimizing shareholder value."

Leo Gontmakher, COO of Cannex, COO at the new 4Front Ventures, and President of Brightleaf, the company's production arm:

"We announced this merger back in November, so our respective teams have had plenty of time to work together on strategy and how best to approach current and future opportunities. We are now ready to hit the ground running, together and seamlessly," Gontmakher said. "At Cannex, our foundation is knowing how to efficiently produce quality, popular products. That foundation paid off, even as the Washington market became more competitive. Cannex's brands continued their success by increasing share, with NWCS largely offsetting pricing pressure with increased volume and efficiencies. Because of our experience, we have solved and iterated on solutions to problems our competitors in nascent markets haven't even contemplated yet.

"Despite this transaction taking substantial time to close, we have been hard at work preparing to introduce Cannex products into new markets, starting with Massachusetts, and I look forward to sharing our progress soon."
