Revenue
Revenue for the year ended December 31, 2021, increased $345.4 million, or 72.5%, compared to the year ended December 31, 2020. The increase in revenue was primarily driven by continued growth in the states where we operated during 2020, with the exception of California, where revenue declined due to a strategic shift to discontinue certain third-party brand sales to focus on Cresco-owned brands. Most notably, revenue growth in Illinois was substantial year-over-year, as the company expanded both its retail and wholesale footprint in the growing adult-use market. In addition, contributed revenue from the Verdant, Bluma, Cultivate, Cure Penn, and Laurel Harvest acquisitions, all of which occurred during 2021 improved revenue in the current period.
COGS and Gross profit
COGS for the year ended December 31, 2021, increased $145.8 million, or 54.1%, compared to the year ended December 31, 2020. The increase was primarily a result of the Verdant, Bluma, Cultivate, Cure Penn and Laurel Harvest acquisitions, including charges of $23.4 million related to the fair value mark-up of inventory from those acquisitions. Further increase was driven by year-over-year revenue growth, increased cultivation capacity in Illinois, and other organic growth.
Gross profit increased by $199.6 million, or 96.6%, for the year ended December 31, 2021, compared to the year ended December 31, 2020 primarily due to the increase in revenue and greater scale in the Company’s established Illinois and Pennsylvania markets, operating synergies realized through acquisitions, and continued efforts to increase cultivation yields. Gross profit as a percentage of revenue for the year ended December 31, 2021, was 49.5% compared with 43.4% for the year ended December 31, 2020; excluding the fair value mark-up of acquired inventory, gross profit as a percentage of revenue for the year ended December 31, 2021, was 52.3% compared with 44.2% in the prior-year period.
Total operating expenses
Total operating expenses for the year ended December 31, 2021, increased $393.5 million, or 171.0%, compared to the year ended December 31, 2020. The increase in total operating expenses was primarily attributable to a goodwill and intangibles impairment charge of $305.9 million recorded in 2021. The charge was driven by a strategic shift in the Company’s California reporting unit, to discontinue certain third-party brand sales to focus on Cresco-owned brand sales. The remaining fluctuation is driven by significant investments in our team, marketing, information technology, and operational infrastructure to drive strategic initiatives that better position the Company for future growth.
Total other (expense), net
Total other (expense), net for the year ended December 31, 2021, decreased $1.3 million, or 3.3%, compared to the year ended December 31, 2020. The decrease in total other (expense), net was due to mark-to-market gains on derivative instruments and liability-classified warrants, primarily due to changes in the Company’s share price and the finalization of certain contingent consideration arrangements. These gains were partially offset by losses on debt extinguishment, losses on investments held at fair value, and higher interest expense that resulted from the loan agreements the Company amended in the fourth quarter of 2020 and then refinanced in the third quarter of 2021.
