Office supplies and service and other general and administrative expenses were $11,068 for the three months ended December 31, 2020 compared to $4,194 for the three months ended December 31, 2019, which represents an increase of $6,874. This increase was primarily due to increased expenditures in office supplies and monthly services at the corporate level, as well as the inclusion of Select, Grassroots, Curaleaf NJ, Arrow, and ATG after the completion of acquisitions in 2020.
Depreciation and amortization was $20,432 for the three months ended December 31, 2020, compared to $10,673 for the three months ended December 31, 2019, which represents an increase of $9,759. The increase was primarily due to the Company’s expansion of retail operations in Florida, New York, Arizona, Connecticut, and Maryland, as well as the inclusion of Select and Grassroots expenses after the completion of the acquisitions in 2020, which largely increased both the Company’s wholesale and retail operations.
Share-based compensation was $16,114 for the three months ended December 31, 2020, compared to $5,663 for the three months ended December 31, 2019 which represents an increase of $10,451. The increase was primarily due to the share-based cost associated with new options and restricted stock units granted in 2020, along with recognizing an $8,493 expense for the Select rollover share fair value adjustment during the three months ended December 31, 2020. See further details regarding the Select rollover share fair value adjustment under the Select acquisition details in the “Recent Acquisitions” section below.
Comparison of the Three Months ended December 31, 2020 and September 30, 2020
Total operating expenses for the three months ended December 31, 2020 were $104,835, an increase of $5,423 or 5%, compared to $99,412 for the three months ended September 30, 2020, which represents 46% and 54% of total revenue for the three months ended December 31, 2020 and September 30, 2020, respectively. The increase in total operating expenses was primarily attributable to an increase in salaries and benefits and sales and marketing as the Company expanded the number of retail dispensaries from 93 as of September 30, 2020 to 96 at December 31, 2020, and increased the level of support staff necessary to run the expanded operations as well as incurred $2,876 and $17,845 in one-time expenses during the three months ended December 31 and September 30, 2020, respectively, largely associated with acquisitions and business development activities.
Salaries and benefits were $33,469 for the three months ended December 31, 2020, compared to $29,130 for the three months ended September 30, 2020, which represents an increase of $4,339. This was due to an increase in headcount at the corporate level as well as headcount from operating markets from organic growth in Florida and Illinois and both organic and acquired growth in Ohio.
Sales and marketing expenses totaled $9,057 for the three months ended December 31, 2020, compared to $5,598 for the three months ended September 30, 2020, which represents an increase of $3,459. The increase was largely due to marketing campaigns throughout the Company during the holiday season, with significant costs incurred with the Select brand, to drive an increase in sales.
Rent and occupancy expenses totaled $5,165 for the three months ended December 31, 2020, compared to $5,799 for the three months ended September 30, 2020. The decrease of $634 was primarily due to the timing of Curaleaf NJ lease accounting implementation in the fourth quarter of 2020 offset by the increase of occupancy expenses related to the new dispensaries and facilities.
Travel expenses totaled $1,111 for the three months ended December 31, 2020, compared to $1,075 for the three months ended September 30, 2020, which represents an increase of $36. Travel expenses between the periods remained relatively consistent as many state COVID-19 restrictions remained in place, limiting travel.
Professional fees were $8,419 for the three months ended December 31, 2020 compared to $20,231 for the three months ended September 30, 2020, which represents a decrease of $11,812. This decrease was primarily due to decreased legal and consulting fees with reduced acquisition activity during the three months ended December 31, 2020. The Company finalized a few significant acquisitions during the three months ended September 30, 2020, including Grassroots and Curaleaf New Jersey, which ultimately resulted in significant legal and consulting fees incurred.
