Glass House Brands Announces the Filing of Prospectus Supplement for Previously Announced At-The-Market Distribution Program

Glass House Brands Inc.

 ("

Glass House

" or the "

Company

") (CBOE CA: GLAS.A.U) (CBOE CA: GLAS.WT.U) (OTCQX: GLASF) (OTCQX:GHBWF) announced today that, further to its news release dated November 13, 2024, it has filed a prospectus supplement (the "

Prospectus Supplement

") to its short form base shelf prospectus dated May 16, 2024 (the "

Shelf Prospectus

") with the securities regulatory authorities in all provinces and territories of Canada.

Glass House Brands Co-Founder, Chairman and CEO stated, “During the third quarter, we delivered record setting results, highlighted by a 128% year-over-year increase in cannabis production, a record low quarterly cultivation cost of $103 per pound and robust growth in retail and consumer packaged goods. All three business lines, wholesale biomass, retail and wholesale CPG, achieved positive year-on-year and sequential revenue growth. As I mentioned on our earnings call, we’ve had many conversations with bankers about raising debt and equity capital over the past six months, and we aim to raise approximately $25 million to fund our Phase 3 expansion. The ATM program is a part of our fund-raising plans. Because we can pay existing obligations from our current operating cash flow and have no upcoming debt maturities for more than two years, we will take our time in choosing the most advantageous pricing and timing to execute the ATM program and other potential financings.”

“We are focused on taking advantage of the current market conditions in California to expand market share, and as such, we are moving ahead aggressively with our expansion plans. We expect to spend $5 million in Capex related to Phase 3 expansion in the fourth quarter of 2024. This retrofit will include the addition of blackout curtains, shade screens, new gutters, a misting system, CO2 systems, and grow pipes. We are particularly excited because unlike our other greenhouses, Greenhouse 2 has nearly 11,000 lights already installed. We expect to start generating revenue by the fourth quarter of 2025, with production estimated at 275,000 pounds of cannabis in its first full year. Besides the additional production volume, we also believe Greenhouse 2 will grow our highest quality flower and be the most consistent year round thanks to the lights and other additional cultivation tools that will be part of the retrofit. The lights will also mean that its production should be less affected by the seasons and would allow us to take advantage of the cyclically higher prices in the front half of the year.”

The Prospectus Supplement has been filed in connection with the Company's previously announced at-the-market distribution program (the "ATM Program"), pursuant to which the Company may from time to time sell up to US$25 million of its subordinate voting shares, restricted voting shares and limited voting shares (collectively, the “Equity Shares”).

Since the Equity Shares will be distributed at trading prices prevailing at the time of the sale, prices may vary between purchasers and during the period of distribution. The volume and timing of sales, if any, will be determined at the sole discretion of the Company's management and in accordance with the terms of the equity distribution agreement dated November 13, 2024 among the Company, ATB Securities Inc. and Canaccord Genuity Corp. (the "Equity Distribution Agreement"). The Company currently intends to use the net proceeds of the ATM Program, if any, primarily for Phase III expansion and/or general corporate purposes.

Sales of Equity Shares, if any, under the ATM Program are anticipated to be made in transactions that are deemed to be "at-the-market distributions" as defined in National Instrument 44-102 – Shelf Distributions, as sales made directly on Cboe Canada or any other recognized Canadian "marketplace" within the meaning of National Instrument 21-101 – Marketplace Operation.

A copy of the Shelf Prospectus, the Prospectus Supplement and the Equity Distribution Agreement may be found on SEDAR+ (www.sedarplus.ca) under the Company's issuer profile.

An electronic or paper copy of the Shelf Prospectus, the Prospectus Supplement and the Equity Distribution Agreement, and any amendment to the documents, may also be obtained without charge, upon request only, by contacting ATB Securities Inc. by email at [e-mail] or from Canaccord Genuity Corp. by email at [e-mail]. The Shelf Prospectus and Prospectus Supplement contain important, detailed information about Glass House and the ATM Program. Prospective investors should read the Shelf Prospectus and Prospectus Supplement before making an investment decision.

This news release shall not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any sale of the Equity Shares in any jurisdiction in which an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. The Equity Shares will not be offered, sold or delivered, directly or indirectly within the United States (as such term is defined in Regulation S under the United States Securities Act of 1933, as amended (the "U.S. Securities Act")) except pursuant to transactions exempt from registration under the U.S. Securities Act and under the securities laws of any applicable state.
