NEWS RELEASE

Greenbriar executes Memorandum of Understanding with Cavco Industries

September 17th, 2024 Trading Symbol: TSX Venture Exchange: GRB

US OTC Market: GEBRF

Scottsdale, Arizona, September 17th, 2024 - Greenbriar Sustainable Living Inc. (TSXV: GRB) (OTC: GEBRF) ("Greenbriar" or the "Company") is pleased to announce that the Company has executed a 12- month Memorandum of Understanding with Cavco Industries Inc. ("Cavco")

Cavco is a builder of manufactured homes in North America with annual audited 2023 revenues of USD $1.8 Billion, USD $158 million in net profit, USD $579 million in working capital and a closing price per share on September 16, 2024 of USD $417.17 on the NASDAQ Global Select Market. With four manufacturing facilities in Texas, North Carolina, California, and Arizona, and more than 230 retail partners, Cavco serves customers across Arizona, California, Colorado, Louisiana, Nevada, New Mexico, North Carolina, Oklahoma, Texas, and Utah. Each of Cavco's factory-built homes are constructed in a controlled indoor environment at a fraction of the time and cost of a site-built home and are partially or fully customizable to a buyer's wish list. Cavco has built and sold more than 500,000 manufactured homes.

The Problem

The U.S. faces a national shortage of affordable homes at current prices and mortgage rates, few Americans can afford to buy a house today. Many are priced out of the American Dream due to high housing prices (national average: USD $412,300), high interest rates (current 30-year mortgage rates are near 6.5%), and supply challenges. Nearly 70% of existing home owners took advantage of low financing rates in 2018-2021, and are thus rate-locked into their current residence. Much of the marginal supply from retiring baby boomers is too big (>3,500 sq ft), in the wrong location (Northeast and Midwest U.S. regions), or too expensive for the current buyers. Within this priced-out buying group are college graduates, down-sizing seniors, and military veterans, and these large cohorts have driven up rents nationally. Americans are currently faced with choosing between mortgage payments they can't afford, high rents which build no equity, or neighborhoods they don't want to live in. California is a compelling example with 39 million official residents and a median family home price of USD $773,363. The Golden State has an estimated shortage of 3.5 million affordable homes.

Toronto Venture Exchange Symbol: GRB | US OTC Symbol: GEBRF Greenbriar received full entitlement for a 995 home, entry-level priced, green subdivision in Southern California in 2021 and a final Precise Development Plan approval in November 2023. Greenbriar has access for 3,500 more homes in Cedar City, Utah. Cavco is a designer and builder of manufactured homes in North America.

On Wednesday, September 11, 2024, the U.S. Department of Housing and Urban Development (HUD) announced it has implemented the most extensive changes to its Manufactured Home Construction and Safety Standards (HUD Code) in more than 30 years. While the HUD Code changes include almost 90 new and updated standards to foster innovation, improve safety and accelerate the production of homes, the HUD's official approval for the building of duplex, triplex and quadplex homes nationwide includes a waiver allowing for immediate construction. This move, to address the nation's affordable housing crisis enables homebuilders to push for more creative housing solutions using manufactured homes. Cavco was the first manufactured homebuilder to work with HUD to build the first single and double-section HUD- approved true duplexes as part of its innovative Anthem series. Cavco launched the first HUD-approved multi-section duplex in Rocky Mount, VA in December 2023 and unveiled the first HUD-approved single- section manufactured duplex in Washington DC in June 2024. This innovative single-section Anthem duplex model, the Blue Ridge, has two separate living units built on one frame or section. One of the living units is a 2 bedroom, 1 bath, and the other a 1 bedroom, 1 bath. Both units offer a spacious, open plan living area and designer kitchen and bathroom and are separated by a firewall.
