Glass House Brands Inc. ("Glass House" or the "Company") (NEO: GLAS.A.U) and (NEO: GLAS.WT.U) (OTCQX: GLASF) and (OTCQX: GHBWF), one of the fastest- growing, vertically-integrated cannabis companies in the U.S., today announced that it has successfully completed its first harvest at the SoCal facility. Upon receipt of all licenses needed to commence cultivation activity on March 11^th, Glass House immediately transferred approximately 30,000 clones from the Company's nearby cultivation facility in Santa Barbara, California to the nursery at the SoCal facility and continued to expand the scale of the grow in following weeks. Management initially projected the first harvest could occur in the third quarter of 2022.

"I would like to congratulate the Glass House Farms team for again exceeding expectations in the startup of our SoCal facility. We now expect that we will achieve revenue from our first harvest at the SoCal facility before the end of Q2 2022, more than four weeks earlier than expected." said Kyle Kazan, Glass House Chairman and CEO. "We remain on track to become the leader in sun grown cannabis cultivation capacity. We believe that our high quality and low-cost production capabilities will provide us with a competitive advantage in California, the world's largest cannabis market. Additionally, the recent closing of the PLUS Products acquisition, signing of definitive documents to acquire three Natural Healing center dispensaries, signing of a binding LOI to purchase the remaining equity and property interest in The Pottery, as well as the planned opening of three new Farmacy locations by the end of Q3 2022 sets the table for Glass House to surpass a $200m revenue run rate in 2023.¹ During this time of industry consolidation, we feel that the execution of our vertical integration strategy will establish Glass House as the dominant player in the California market, and as the most attractive partner in Calfornia for brands, MSOs and retail operators. They say seeing is believing, and we warmly invite all investors to join us at our SoCal facility for our 1^st Annual Glass House Investor Sesh on June 24^th. We'll be providing guided tours of the greenhouses and Q&A with the senior management team." (For more information, and to register click here)

"The cultivation team has pushed the envelope of what is possible in cannabis cultivation." said Graham Farrar, President and Chief Cannabis Officer, "At our Padaro farm, the time from property acquisition to harvest was almost 34 months; at SoCal it took 9 months. Our SoCal facility canopy has reached in 10 weeks what it took us 10 months to achieve at Padaro. While we are still in the process of optimizing the cultivation process here, all indications are that we'll be able to achieve our quality and cost targets. We are excited to have completed our first harvest and are looking forward to completing our first sale of cannabis grown at the SoCal facility before the end of Q2 2022."

Graham continued, "This is a true Unicorn facility that will enable us to produce high quality sun-grown cannabis at close-to-outdoor cost, providing a durable competitive advantage that allows us to be successful in any market condition. In addition, the facility's location in an ideal climate; as well as its solar and cogeneration capabilities make it significantly more energy-efficient, with remarkably lower carbon emissions compared to other greenhouse operations."

The SoCal Facility consists of six, high-tech, environmentally controlled agricultural greenhouses totaling approximately 5.5 million square feet, located on a 165-acre property in Ventura County, California. The Phase I retrofit involves the optimization of approximately 1.7 million square feet of the SoCal facility for cannabis cultivation. Included in the first phase retrofit is the conversion of two greenhouses. One will consist of a nursery, growing clones to support the entire facility; and the other will be used for flowering and have a capacity of approximately 180,000 dry pounds of cannabis per year. Also included, and under construction, is a packhouse for processing and a separate distribution center which will support the cultivation operations.
