WAKEFIELD, Mass., May 4, 2020 — Curaleaf Holdings, Inc. (CSE: CURA) (OTCQX: CURLF) (“Curaleaf” or the “Company”), a leading vertically integrated cannabis operator in the United States, has signed HERBL, California’s largest cannabis distributor and supply chain solutions company, as the exclusive distributor of Select products in California. This partnership with HERBL will allow for an increase in deliveries, expanded customer footprint, a more cost efficient delivery method and opportunity for continued growth for the Select brand across the state.

The decision marks another step forward in Curaleaf’s business consolidation strategy as the Company continues to grow Select across the country. Through its vast network, the HERBL partnership will bring Select to more than 850 licensed dispensaries and delivery partners across the state of California, the world’s largest cannabis market. Curaleaf’s California sales, manufacturing and marketing teams will now focus primarily on new product development and brand marketing for Select, while HERBL will serve as a logistics, retail services, inventory management and distribution partner in the state.

The Select brand, which was acquired by Curaleaf in February 2020, can now be found in Oregon, California, Nevada, Arizona, Colorado, Michigan, Maryland and Oklahoma. The brand is expanding rapidly into additional states across the country, with Curaleaf now operating in 17 states total.

HERBL will serve as the exclusive distribution partner for Select products in California, including its flagship vape cartridge Select Elite, Select Elite Gummies, Select CBD, Ratio Drops and the newly launched enhanced live resin vape cartridge, Select Elite Live. Outside of California, the Select brand will continue to sell and distribute Select products via internal channels, as it always has.

“With our HERBL partnership, California customers can expect the same Select products they know and love, with the added layer of enhanced access and new distribution efficiencies to make the process more streamlined for all,” said Mark Russ, Senior Vice President of Sales at Curaleaf. “The partnership comes at an exciting time, as we’ve just launched our new enhanced live resin product, Select Elite Live, and we’re looking forward to introducing this product to even more dispensary doors, patients and consumers across the state,” Russ continued.

“Select products are a favorite with dispensaries and consumers alike, and the HERBL team is ready to scale and grow the brand’s reach in California to its fullest potential,” said Mike Beaudry, founder and CEO of HERBL.

During the COVID-19 pandemic, cannabis has been deemed an essential service in most states, including California, and the industry continues to serve patients and customers. At Curaleaf dispensaries, customers can expect to see heightened safety and hygienic measures including increased cleaning protocol, social distancing, new delivery options, curbside pickup, and dedicated hours for seniors and other at-risk populations. The company’s focus remains on the safety of customers, patients and employees at this time.
