WAKEFIELD, Mass., Dec. 16, 2021 – PRESS RELEASE – Curaleaf Holdings Inc., a leading international provider of consumer products in cannabis, announced that it has closed its previously announced private placement of 8% senior secured notes due 2026 (the "Notes"), with a settlement date of Dec. 15, 2021, for aggregate gross proceeds of $425 million (the "Offering"). The Notes are governed by a trust indenture that was entered into on closing of the Offering (the "Indenture").

The Indenture enables the Curaleaf to issue additional notes on an ongoing basis as needed, subject to maintaining leverage ratios and complying with the other terms and conditions of the Indenture. In addition, the Indenture permits up to $200 million of senior bank financing.

The net proceeds from the Notes will be used to refinance existing indebtedness, for working capital, and to pay transaction fees and expenses. The Notes were issued at 100% of face value, are senior secured obligations of the company, and bear interest at a rate of 8% per annum, payable semiannually in equal installments until the maturity date, unless earlier redeemed or repurchased. The Notes will mature on Dec. 15, 2026.

"We are pleased to successfully complete what we believe is the largest debt financing of any publicly traded MSO to date, underscoring our leading market position and strong financial profile,” Curaleaf CEO Joe Bayern said.

“With the closing of this offering and refinancing of our existing debt, we have meaningfully reduced the average interest rate on our outstanding debt,” he said. “In addition, by strengthening our already solid balance sheet and gaining increased flexibility to raise additional debt financing as needed, Curaleaf is extraordinarily well-positioned to execute both organic and M&A growth initiatives and continue building leading brands."

Seaport Global Securities LLC and Canaccord Genuity Corp. (the "Agents") acted as placement agents for the Notes in the U.S. and Canada, respectively.

As the cannabis industry turns the corner into a new year, many people within the space and in government and policy are advocating for more representation and ownership for Black, Indigenous, and People of Color (BIPOC) in cannabis. In many cases, they’re making that a reality, all the while acknowledging that much more work needs to be done. 

At Cannabis Conference 2021, Cannabis Business Times and Cannabis Conference awarded Ngiste Abebe, vice president of public policy at Columbia Care, with a Cannabis Leadership Award. Abebe champions for social equity in the market, and broke down what that really means in an interview for a CBT profile.

“The three pillars of equity that I always raise when I’m talking about equity and policy, which is, first, stop the harm,” she told CBT. “You know, not just stopping arrests, but expungements, resentencing, all of those things. [Second], equity in the cannabis industry means making sure that there’s licensed program support for folks who were impacted by prohibition having the opportunity within the industry. And then equity beyond that, because not everybody who was harmed by prohibition wants to own a license; how else are we restoring the hopes and dreams that were shattered by prohibition?”

These are some of the social-equity storylines that CBT has been following this year:

Internships for HBCU Students and Graduates

The U.S. Cannabis Council (USCC) recently announced that it has partnered with the Congressional Black Caucus Foundation to launch the Spring 2022 Pathways to the C-Suite internship program. Seniors and recent graduates from historically black colleges and universities (HBCUs) will work with eight of USCC’s member companies and organizations.

New Mexico’s Cannabis Control Division (CCD) has announced that it issued the state’s first adult-use cannabis licenses Dec. 15 to three producers.

“This is a big day for New Mexico’s future,” said Gov. Michelle Lujan Grisham, in a public statement. “I am proud of the work this administration has done. Securing legalization was only the first step. Creating an industry where New Mexico entrepreneurs can prosper and where communities can reap the economic benefit of a new industry is crucial. And today’s news is a key milepost in that ongoing effort.”

The first producer license went to Steve Martinez, Mitchell Martinez, and Tony Martinez, a father-and-sons team in Aztec.

The first micro producer licenses were awarded to Carver Family Farm in Albuquerque and BAUDABOOMZ2 in Edgewood.

“With the issuing of these three licenses, the adult-use cannabis industry in New Mexico is officially up and running,” said Regulation and Licensing Department (RLD) Superintendent Linda M. Trujillo, in a public statement. “In the coming days and weeks, we look forward to licensing more cannabis businesses and microbusinesses so that entrepreneurs, communities and the state can maximize the economic opportunities created by a thriving cannabis industry.”

The Ohio Senate has passed legislation that would make sweeping changes to the state’s medical cannabis program, according to a WBNS report.

Senate Bill 261, which was introduced by State Sen. Steve Huffman last month, would allow physicians to recommend cannabis for any condition, increase the number of dispensary licenses in the state, and allow cultivators to expand their operations.

The measure would also create a new Division of Marijuana Control within the Ohio Department of Commerce to oversee the state’s medical cannabis dispensaries, which are currently regulated by the Ohio Board of Pharmacy.

The bill stipulates that there should be one dispensary for every 1,000 of the first 300,000 registered medical cannabis patients, and proposes adding more retailers as needed, WBNS reported.

The Colorado Department of Revenue (DOR) and Colorado Department of Public Health and Environment (CDPHE) have issued a health and safety advisory after identifying a potentially unsafe cannabis concentrate produced by Innovative Fusion LLC, which does business as DRIP.

The DOR identified batches of medical and adult-use cannabis that had not been tested, were not tested properly, or were confirmed to contain levels of contaminants, potency, and/or homogeneity that were above the state’s acceptable limits.

The DOR and CDPHE have deemed all batches of medical and adult-use cannabis produced by DRIP to be a potential threat to public health and safety.

The contaminated or untested batches were sold to consumers in Colorado before Dec. 10, and the health and safety advisory states that consumers who experience adverse health effects after consuming the product should seek medical attention and report it to the dispensary where they purchased the product.

In addition, those who have cannabis products produced by the following licensees should return them to the dispensary where they were purchased:

The U.S. Cannabis Council (USCC) is on a mission to create a diverse and inclusive cannabis industry with equal opportunities for all entrepreneurs, which means shattering what USCC Director of Social Equity & Inclusion Tahir Johnson views as the biggest barrier of entry for Black business owners: lack of access.

“U.S. Cannabis Council’s goal or mission is to make sure it’s a diverse and inclusive industry that’s prosperous for everyone, not only in equity and license ownership, but also in making sure that the cannabis industry itself is diverse,” Johnson told Cannabis Business Times and Cannabis Dispensary.

To improve access to the industry for Black entrepreneurs, the USCC is launching a new internship program in partnership with the Congressional Black Caucus Foundation (CBCF), as well as maintaining its diversity, equity and inclusion (DEI) task force, which is about to launch a tool to assess member companies’ success in these areas.

‘A Strong Pathway to Future Leadership’

The Spring 2022 Pathways to the C-Suite internship program will partner Black college seniors and recent college graduates with eight of USCC’s member cannabis companies and organizations, including ACHEM, Canopy, Columbia Care, Curaleaf, Holistic, Marijuana Policy Project, USCC, and Weedmaps.

The deadline for applications was Dec. 3, and the internship program officially kicks off in January.

Driving up yields is key to greater profit margins in the cannabis space, especially for indoor operators who have to balance the costs of running and maintaining their facility.

While several factors contribute to the end result of any grow cycle, the inputs that lead to good yields are primarily three-fold: environmental control, lighting and watering or fertigation, according to Geoff Brown, the vice president of product and business development at AGronomic IQ, formerly Quest IQ.

“We sort of call it the triangle of good yields,” Brown said. “And investing in a purpose-built, unitary solution removes the HVAC challenge for growers.”

Choosing an all-in-one system to deliver the most precise temperature and humidity control allows indoor operators to take a hands-off approach to HVAC and a hands-on approach to what they entered the business for—growing cannabis.

While some indoor operators walk into a retrofitted facility where they utilize numerous pieces of HVAC equipment in a Frankenstein approach to controlling their environments, the cost and time associated with maintenance to as many as 15 different units results in distracted growers who are the mercy of 15 sources of failure or breakdowns. In addition, those units sometimes work against one another, driving up energy costs that may exceed a facility’s power limit.

Investing in unitary HVAC equipment that is engineered from the ground up and purpose-built for the indoor cannabis space may be an unbudgeted cost for new operators entering the industry, but choosing the right system can help growers maximize their yields and provide a return on investment (ROI) that supports energy efficiency, consistent grow cycles and scalability.

Editor’s Note: This article is an extract taken from the Getting Grow Rooms Rightbook, published by AGronomic IQ. The book can be downloaded in its entirety at AGronomicIQ.com.

Ensuring that HVAC equipment is properly sized for its grow room application is critical for growers, as it will help define the success and profitability of your operation.

Units that are too big cost more to buy and use far more energy than necessary and could possibly result in an overcooled or overdried space. Similarly, equipment that is too small will be unable to keep up with demand and result in space conditions such as overheating or excess humidity, and these issues could potentially reduce crop quality or put plants in danger.

Given the many variables at play in grow rooms, significantly more than in standard environments, and considering most engineers are unfamiliar with this specific application, sizing calculations for grow room HVAC has been a very challenging task. This is largely due to misinformation and a lack of knowledge among those involved in the facility design industry. Even the most technically qualified engineering firms have had to guess at a considerable amount of the science and mechanics behind creating optimal grow environments due to a lack of HVAC design standards for engineers, and because the cannabis industry is so secretive about what works and what does not. In this industry, engineering jobs are extremely complex and involve dozens more variables than designing traditional HVAC systems for commercial buildings.

Getting grow room specifications right requires careful modeling of grow cycles, transpiration rates, temperature and humidity specifications, lighting loads, and irrigation loads, just to name a few. It also requires careful modeling of external factors, including annual temperature and humidity ranges, type of building structure, solar impacts of mixed-light sources, etc. Some of these factors may vary by type of plant and strain, which only further complicates the matter.

The Unitary Advantage

St. Louis Mayor Tishaura O. Jones signed a cannabis decriminalization bill into law Dec. 13 that repeals city ordinances that previously made it illegal to possess 35 grams or less of cannabis, according to the St. Louis Post-Dispatch.

The new law stipulates that the odor or presence of cannabis can no longer be sole probable cause for search and arrest, the news outlet reported. The measure also prohibits police from enforcing state and federal laws prohibiting the possession of small amounts of cannabis, with certain exceptions.

In a news conference before the bill signing, Jones said enforcing strict cannabis laws takes police resources away from violent crime, according to the St. Louis Post-Dispatch, and that the new policy will reduce racial disparities in policing.

Malta became the first European country to legalize adult-use cannabis Dec. 14 when its parliament approved legislation that would legalize the cultivation and possession of cannabis for adults 18 and older.

RELATED: Malta to Legalize Cannabis Cultivation, Possession for Personal Use

The bill, which is expected to be signed into law by the president, allows adults to possess up to 7 grams of cannabis and to cultivate up to four plants, but consuming cannabis in public or in the presence of minors will remain illegal, according to an AP News report.

Those cultivating plants for personal use can store up to 50 grams of dried cannabis, AP News reported, and the law allows non-profit clubs to distribute cannabis and cannabis seeds to their members.

The legislation also establishes an authority that will work with Malta’s government to develop national policy regulating cannabis use, according to the news outlet.

New Mexico’s Cannabis Control Division (CCD) is now accepting applications for all cannabis license types as it works to get the state’s adult-use program up and running.

The department, which had received more than 1,500 adult-use cultivation license applications as of mid-November, has expanded its application process to include manufacturing and retail businesses “to further streamline the licensing process,” according to a press release.

“The Cannabis Control Division’s licensing system is open for business,” Regulation and Licensing Department (RLD) Superintendent Linda M. Trujillo said in a public statement. “As part of the CCD’s mission to stand up a thriving adult-use cannabis industry in New Mexico, we are expanding user-friendly online platform to allow applicants to start the licensing process now for more business types so that they can be prepared as more rules are being quickly finalized.”

Prospective entrepreneurs can access the New Mexico’s licensing application system online, but the CCD will not issue cannabis licenses until the state’s adult-use rules have been finalized, according to the press release.

Final regulations for New Mexico’s adult-use cannabis industry must be adopted by a Jan. 1, 2022 deadline and sales are set to launch by April 1.

As a cannabis company, secured debt may be your only option for a line of credit or for funding the evolution of your business.

Secured debt is where the lender takes a lien against either all assets or a particular set assets of a borrower as collateral for a loan. As can be imagined, trudging blindly into this type of debt can sink your business. Moreover, there are particular concerns when cannabis companies incur secured debt.

Increasingly, experienced secured debt lenders are entering this space, but a significant portion of those potential partners remain prohibited by federal law from participating in cannabis company debt. In the meantime, it falls disproportionately on cannabis companies to educate and steward and carefully consider potential debt partners. Unless you have been active in the space before, it is going to be hard for you to judge what is right, wrong or weird without trusted advisors.

The responsibilities between a borrower and the lender are commonly misunderstood. It is not an equal (or close to equal) partnership, which is the universal issue of this article. If you incur secured debt, it is your responsibility to understand that your lender has a right to your collateral—a right that is superior to rights of all others.

The consequence of misunderstanding this relationship can be the lender calling default on your loan.

Grasping this responsibility involves two important concepts under Article 9 of the Uniform Commercial Code (UCC):

Malta is poised to become the first European country to legalize cannabis cultivation and possession for personal use.

The Maltese parliament is expected to vote in favor of the legislation on Dec. 14, according to The Guardian. The law will then be signed by the president and is expected to be implemented by this weekend.

The legislation would legalize the possession of up to 7 grams of cannabis for adults 18 and older, The Guardian reported, as well as allow adults to grow up to four cannabis plants at home for personal use.

The new law would also allow non-profit cannabis clubs to cultivate plants to distribute to their members, according to the news outlet. Club membership would be limited to 500 people and clubs can only distribute up to 7 grams of cannabis to each member per day, with a maximum of 50 grams per month.

Cannabis policy reform has been on the rise in Europe this year. Germany is also on the cusp of legalizing adult-use cannabis; its new governing coalition is expected to introduce legislation that would allow specialized shops to sell cannabis products.

More than 400 New York municipalities have opted out of adult-use cannabis sales ahead of a Dec. 31 deadline to do so, with many officials deciding to hold off on hosting dispensaries until regulators provide more clarity on the program, according to an NBC New York report.

The state’s adult-use cannabis law allows local municipalities to opt out of hosting cannabis retailers and consumption lounges when sales start next year, although local governments cannot ban cannabis possession within their jurisdictions, NBC reported.

As of Dec. 10, 252 towns and 164 villages have opted out of hosting adult-use dispensaries, according to the news outlet, while 279 towns and 179 villages have opted out of hosting consumption sites.

These municipalities represent more than a quarter of New York’s towns and 31% of the state’s villages, NBC reported.

Only a few of New York’s cities have opted out, and none of the state’s largest cities have officially said no to cannabis sales, according to NBC.

OAKLAND, Calif., Nov. 29, 2021 /CNW/ - PRESS RELEASE - Harborside Inc., a California-focused, vertically integrated cannabis enterprise, has announced that it has entered into definitive agreements to acquire UL Holdings Inc. (Urbn Leaf), a California cannabis retailer with a dominant position in Southern California, and  LPF JV Corporation (Loudpack), a manufacturer, cultivator and distributor of award-winning cannabis brands in California. Following completion of the transactions, Harborside is expected to be renamed StateHouse Holdings, subject to shareholder and regulatory approval.

Management believes that StateHouse, which is expected to trade under a new symbol, will be the largest and most developed cannabis platform in the state of California with retail, brands, processing, manufacturing, distribution and cultivation. Management believes that StateHouse will have the highest estimated annual revenue and brand market share among its current publicly-listed California peers, providing the company with a strong platform for growth as a consolidator of California's cannabis industry. Through the first nine months of 2021, Harborside, on a pro-forma basis including revenue of Sublimation Inc. (Sublime) for the entire period, had gross revenue of US$57.8 million, while Urbn Leaf and Loudpack had revenue of US$45.9 million and US$61.4 million, respectively. Therefore, on a pro forma basis, management estimates that StateHouse would have generated gross revenue of approximately US$165 million for the same period.

Ed Schmults, the current CEO of Urbn Leaf, is expected to be appointed as CEO of StateHouse upon completion of the Urbn Leaf transaction and will be joining the Board of Directors of StateHouse. Marc Ravner, the current CEO of Loudpack, is expected to be appointed as president of StateHouse upon completion of the Loudpack transaction and will be joining the Board of Directors of StateHouse. Matthew Hawkins, current chairman and interim CEO of Harborside, will remain as Chairman of the Board of StateHouse. 

"Since reconstituting the company's board of directors last year, our team embarked upon an ambitious mission to create a unique platform capable of consolidating California and driving significant growth through added scale. With these transactions, we are working to create a west coast cannabis powerhouse," said Hawkins. "The combination of high-quality assets, increased scale and experienced leadership will drive tremendous value for shareholders. California is one of the world's largest legal cannabis markets, with sales expected to reach US$7.4 billion by 2025. StateHouse will have a unique ability to navigate the operating challenges in the state and capitalize on the combined potential of the businesses we are acquiring. We are building what we believe is the ideal platform to consolidate the California cannabis sector, positioning us for long-term growth in both market share and profitability. Ed Schmults, an experienced leader with a proven retail and cannabis track record, is the right person to lead StateHouse into the future."

The transaction was structured based upon the relative enterprise values of Harborside, Urbn Leaf and Loudpack. The aggregate consideration for the transactions will be met through the issuance of 151,427,786 subordinate voting shares of Harborside (SVS) and the assumption and restructuring of debts and other obligations as well as the issuance of 2,000,000 warrants at a strike price of US$2.50 per SVS. Harborside, Urbn Leaf and Loudpack noted that the structure of the transaction and overall consideration contemplates both a return to normalized enterprise valuations for California-focused cannabis companies and the potential for StateHouse to become a leading participant in that market.  Based upon the relative enterprise value of each party, following closing of the transactions, existing Harborside, Loudpack and Urbn Leaf shareholders will own approximately 35%, 39% and 26% of StateHouse, respectively, on a fully diluted basis and assuming conversion of all multiple voting shares of Harborside (MVS) to SVS.

In connection with the transactions, management has entered into a letter of intent with Pelorus Equity Group to complete the Real Estate Financing (as defined below) of US$77.3 million of non-dilutive real estate debt financing, which unlocks significant value from the StateHouse real estate portfolio and provides significant growth capital for the business.

Louisville, Colorado, Dec. 09, 2021 (GLOBE NEWSWIRE) PRESS RELEASE -- CEA Industries Inc., doing business as Surna Cultivation Technologies, today announced it has become a value-added reseller of Air Sniper air sanitization products.

“Surna Cultivation Technologies has added another product line to its expanding list of proprietary and curated offerings and is proud to announce our partnership with Air Sniper as a value-added reseller of their high-quality air sanitization products,” said Troy Rippe, Surna’s Vice President of Operations and Development. “With Air Sniper’s sanitization solutions, we are able to deliver our HVACD systems alongside a proven UVC technology to help our customers’ plants thrive in a clean environment.”

Air Sniper uses powerful bulbs and reflective paneling to control the intensity, dwell time, cubic feet per minute (CFM) of air movement, and irradiation proximity within the equipment creating a pathogen destruction environment. Together, these elements form an environment within the Air Sniper unit that is rich with Ultraviolet Germicidal Irradiation (UVGI). Traditional air purifiers work by trapping harmful particles in filters, but they gradually become ineffective as they get saturated and eventually clogged. Air Sniper offers a more effective method to eliminate airborne contaminants. These units go beyond air filtration by using UVC bulbs (UVC light disrupts the DNA and RNA of pathogens, eliminating their ability to replicate) keeping the air and plants clear of damaging contaminants such as mold, allergens, and even viral pathogens.

The product line includes:

Standalone Air Sanitization Solutions - Eliminates airborne contaminants that pose a threat to plants. Kills mold, mildew, and bacteria. These plug-and-play units are easily mounted and are Wi-Fi enabled for easy installation and monitoring.

System Integrated Air Sanitization Solutions - Can be easily incorporated into new or existing HVAC systems to protect plants from harmful mold, bacteria, and other contaminants. These units are placed on the return and/or supply side of the system and use the power of the mechanical system rather than having their own internal fan. Third party test results show that over 99.9% of airborne viruses, bacteria and molds, including botrytis (grey mold) and powdery mildew, are completely eliminated before they can harm plants.
