Concerns about Marijuana Efficacy and Safety

Adverse publicity reports or other media attention regarding the safety, efficacy and quality of marijuana in general, or associating the consumption of adult-use and medical marijuana with illness or other negative effects or events, could have such a material adverse effect. There is no assurance that such adverse publicity reports or other media attention will not arise. A negative shift in the public's perception of cannabis, including vaping or other forms of cannabis administration, in the U.S. or any other applicable jurisdiction could cause State jurisdictions to abandon initiatives or proposals to legalize medical and/or adult-use cannabis, thereby limiting the number of new State jurisdictions into which Curaleaf could expand. Recent medical alerts by the Centers for Disease Control (CDC) and future bans on the sale of vaping products in the locations Curaleaf serves, and recent state health agencies’ approaches to vaping related illness and other issues directly related to cannabis consumption could potentially create an inability to fully implement Curaleaf's expansion strategy and may have a material adverse effect on Curaleaf's business, results of operations or prospects.

This year, the U.S. media has increasingly reported an apparent new trend in the distribution to consumers of hemp-based products purporting to contain the ingredient Delta-8 tetrahydrocannabinol (“Delta-8 THC”), one of many cannabinoids that are found in the cannabis plant. Most Delta-8 THC on the market is derived from the chemical conversion of hemp-derived cannabidiol (“CBD”). Notably, the Drug Enforcement Act includes Delta-8 THC on its list of controlled substances (updated August 2020) under “tetrahydrocannabinols,” but Section 12619(b) of the 2018 Farm Bill legislation expressly carved out “tetrahydrocannabinols in hemp” of the 2018 Farm Bill thus leaving some lack of clarity regarding the legal status of this substance. Delta-8 THC products appear to offer a similar but somewhat less intoxicating psychotropic effect in users.

Anecdotal reports indicate that Delta-8 THC products are being manufactured and distributed in the U.S outside of state licensed cannabis processors and dispensaries including, for example, through convenience stores, gas stations and even via the Internet to consumers under the age of 21. Moreover, these products do not appear to be subject to the testing requirements applicable to Delta-9 THC products. These products are being sold without state mandated cannabis excise taxes applied, thus leading to significant price differentials with Delta-9 THC products.

Given the pricing differential and the absence of state cannabis excise taxes, continued proliferation of unregulated Delta-8 THC products through unlicensed distribution points could ultimately alter certain elements of the current Delta-9 THC market in the U.S. Recently, several states have begun to promulgate new regulations and interpretations of existing regulations that effectively prohibit the development of Delta-8 THC products. For example, New York issued interpretive guidance stating that “Delta-8 THC products are not permitted in the New York State Cannabinoid Hemp Program. Retailers are not permitted to sell Delta-8 THC products and processors are not permitted to manufacture them.” Massachusetts took another approach by declaring that since “delta-8 THC is not naturally occurring in hemp (except for possible trace amounts), to produce delta-8 THC in commercial quantities it must be derived from hemp synthetically. While the Farm Bill did remove hemp from the Controlled Substances Act, it did not impact the control status of synthetically derived cannabinoids, thus delta-8 THC remains a controlled substance, regardless of the source. As a result, we do not allow hemp-derived delta-8 THC products to be processed or sold in Massachusetts.” If this trend continues, the potential impact of Delta-8 THC products on the Delta-9 THC cannabis market could be blunted.

COVID-19

The novel coronavirus commonly referred to as "COVID-19" was identified in December 2019 in Wuhan, China. On January 30, 2020, the World Health Organization declared the outbreak a global health emergency, and on March 11, 2020, the spread of COVID-19 was declared a pandemic by the World Health Organization. On March 13, 2020, the spread of COVID-19 was declared a national emergency. The outbreak spread throughout Europe, the Middle East and North America, causing companies and various international jurisdictions to impose restrictions such as quarantines, business closures and travel restrictions. While these effects have been mitigated by the application of precautions such as social distancing and masking as well as the development and distribution of vaccines, the situation remains fluid. While the Company has continuously sought to assess the potential impact of the pandemic on its financial and operating results, any assessment continues to be subject to uncertainty as to probability, severity and duration of the pandemic as reflected by infection rates at local, state, and regional levels. The Company has attempted to assess the impact of the pandemic by identifying risks in the following principal areas:

• Mandatory Closures. In response to the pandemic, many states and localities implemented mandatory closures of, or limitations to, businesses to prevent the spread of COVID-19; this impacted the Company’s operations. Subsequently, the Company’s business was deemed an "essential service," permitting it to stay open despite the mandatory closure of non-essential businesses. More recently, the mandatory closures that impacted the Company’s operations were lifted and the Company resumed full operations, albeit subject to various COVID-19 related precautions and changes in local infection rates. The Company’s ability to generate revenue would be materially impacted by any future shut down of its operations.

• Customer Impact. While the Company has not experienced an overall downturn in demand for its products in connection with the pandemic, if its customers become ill with COVID-19, are forced to quarantine, decide to self-quarantine or not to visit its stores or distribution points to observe "social distancing", it may have material negative impact on demand for its products while the pandemic continues. The Company implemented measures, where permitted, such as "curb side" sales and delivery, to reduce infection risk to its customers, regulators may not permit such measures, or such measures may not prevent a reduction in demand. Notably, on May 16, 2021, the Centers for Disease Control issued the following revised guidance for individuals who have received one of the COVID-19 vaccines: “Fully vaccinated people can resume activities without wearing a mask or physically distancing, except where required by federal, state, local, tribal, or territorial laws, rules, and regulations, including local business and workplace guidance.” As a result, the Company recently revised its masking and social distancing directives for both employees and customers/patients in light of this recent CDC guidance. That said, there is no assurance that new, vaccine resistant COVID-19 variant strains will not appear which could result in an increase in infections and a corresponding impact to customer activity. In particular, the B.1.617.2 (Delta) variant was classified by the CDC as a ‘variant of concern’ because it spreads from person to person more easily than other variants and may cause more severe disease.

• Supply Chain Disruption. The Company relies on third party suppliers for equipment and services to produce its products and keep its operations going. If its suppliers are unable to continue operating due to mandatory closures or other effects of the pandemic, it may negatively impact its own ability to continue operating. At this time, the Company has not experienced any failure to secure critical supplies or services. However, disruptions in the Company’s supply chain may affect its ability to continue certain aspects of the Company’s operations or may significantly increase the cost of operating its business and significantly reduce its margins.

• Staffing Disruption. Earlier in the pandemic, the Company implemented among its staff where feasible "social distancing" measures recommended by such bodies as the Centers for Disease Control (CDC), the Presidential Administration, as well as state and local governments. The Company cancelled non-essential travel by employees, implemented remote meetings where possible, and permitted all staff who can work remotely to do so. For those whose duties require them to work on-site, measures were implemented to reduce infection risk, such as reducing contact with customers, mandating additional cleaning of workspaces and hand disinfection, providing masks and gloves to certain personnel, and contact tracing following reports of employee infection. More recently, following the increase in vaccination rates in the states in which the Company has operations, the Company has seen a decrease in the incidence of employees reporting COVID-19 infections or exposures. Moreover, the Company is encouraging its employees to become vaccinated and is requiring employees to verify their vaccination status; those employees who are not vaccinated are required to continue to follow masking guidelines while those who are vaccinated are given the option to forego masking at the workplace. Nevertheless, there is no assurance that new, vaccine resistant COVID-19 strains will not appear which could result in an increase in infections and a corresponding increase in employee absenteeism. If such absenteeism increases, the Company may not be able, including through replacement and temporary staff, to continue to operate at desired levels in some or all locations.

• Regulatory Backlog. Regulatory authorities, including those that oversee the cannabis industry on the state level, have been heavily occupied with their response to the pandemic. These regulators as well as other executive and legislative bodies in the states in which the Company operates may not be able to provide the level of support and attention to day-to-day regulatory functions as well as to needed regulatory development and reform that they would otherwise have provided. Such regulatory backlog may materially hinder the development of the Company’s business by delaying such activities as product launches, facility openings and approval of business acquisitions, thus materially impeding development of its business. The Company is actively addressing the risk to business continuity represented by each of the above factors through the implementation of a broad range of measures throughout its structure and is reassessing its response to the COVID-19 pandemic on an ongoing basis.

• Vaccination rates. On December 11, 2020, the federal Food and Drug Administration (FDA) issued an emergency use authorization (EUA) for the Pfizer BioN-Tech COVID-19 vaccine, the first such approval. Additional EUAs were issued on December 18, 2020 for a vaccine created by Moderna, and on February 27, 2021 for a vaccine created by Janssen Biotech (a Johnson & Johnson affiliate). As of June 24, 2021,the CDC reports that 320.7 million vaccine doses have been administered. Overall, about 178.3 million people, or 53.7% of the total U.S. population, have received at least one dose of vaccine. About 151.3 million people, or 45.6% of the total U.S. population, have been fully vaccinated. As of now, the supply of vaccines in the states in which the Company does business appears to be sufficient to meet the demand of all those who seek to be vaccinated. That said, there can be no assurance of when the Company’s employees in any particular jurisdiction will access the vaccine. Moreover, there can be no assurance that all employees will choose to avail themselves of the vaccine or, if so, when they will choose to do so. The same applies to the Company’s patients, customers, regulators, and suppliers. Consequently, the COVID-19 risk factors described above continue to be applicable.

● Continuing restrictions in Europe. Countries in Europe continue to be severely impacted by COVID-19. Each country in Europe has adopted its own public health response, but the larger economies (being Germany, the UK, Italy, Spain and France) are relaxing previously strict “lock-down” measures and non-essential businesses, closed for extended periods are beginning to open subject to social distancing and other operating restrictions. Cannabis consumption in Europe is however exclusively medical, and like other medicines, supply of medical cannabis has continued during the pandemic, with doctors and pharmacies adopting tele-medicine to hold consultations and supply prescriptions to patients. Import and export licenses have been granted to allow cannabis and medical products to move between countries (albeit sometimes with regulatory delays as public health authorities have faced a number of pandemic-related priorities during the period). Whilst the Company has faced delays and difficulties (similar to the impact detailed above in relation to operations in North America) the Company’s manufacturing sites in Spain and the UK, and its cultivation site in Portugal, have continued operations without significant disruption. Whilst countries are beginning to lift restrictions the Company expects operations to continue to be impacted by COVID-19 related public health restrictions until such time as infection rates in relevant countries, mortality rates, and vaccine numbers, reach levels that allow Governments to lift current restrictions fully.

The above risks individually or collectively may have a material impact on the Company’s ability to generate revenue. Implementing measures to remediate the risks identified above may materially increase the Company’s costs of doing business, reduce its margins and potentially result in losses. While the Company has not to date experienced any overall material negative impact on its operations or financial results related to the impact of the pandemic, so long as the pandemic and measures taken in response to the pandemic are not abated, substantial risk of such impact remains, which could negatively impact the Company’s ability to generate revenue and/or profits, raise capital and complete its development plans.
