Description of the Business
Description of the Business	1. Description of the Business BuzzFeed, Inc. (referred to herein, collectively with its subsidiaries, as “BuzzFeed or the “Company”) is a global media company with social, content-driven publishing technology. BuzzFeed provides breaking news, original reporting, entertainment, and video across its owned and operated and the social web to its global audience. BuzzFeed derives its revenue primarily from content, advertising and commerce sold to leading brands. The Company has one reportable segment. On December 3, 2021 (the “Closing Date”), the Company consummated the previously announced business combinations in connection with (i) that certain Agreement and Plan of Merger, dated June 24, 2021 (as amended, the “Merger Agreement”), by and among 890 5th Avenue Partners, Inc., a Delaware corporation (“890”), Bolt Merger Sub I, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of 890 (“Merger Sub I”), Bolt Merger Sub II, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of 890 (“Merger Sub II”), and BuzzFeed, Inc., a Delaware corporation (“ Legacy BuzzFeed”), pursuant to which (a) Merger Sub I merged with and into Legacy BuzzFeed (the “First Merger”), with Legacy BuzzFeed surviving the First Merger as a wholly-owned subsidiary of 890 and (b) immediately following the First Merger, Legacy BuzzFeed merged with and into Merger Sub II (the “Second Merger” and, together with the First Merger, the “Two-Step Merger”), with Merger Sub II surviving the Second Merger as a wholly-owned subsidiary of 890; and (ii) the Membership Interest Purchase Agreement, dated as of March 27, 2021 (as amended, the “C Acquisition Purchase Agreement”), by and among Legacy BuzzFeed, CM Partners, LLC, Complex Media, Inc., Verizon CMP Holdings LLC and HDS II, Inc., pursuant to which the surviving entity acquired 100% of the membership interests of CM Partners, LLC. CM Partners, LLC, together with Complex Media, Inc., is referred to herein as “Complex Networks.” The Two-Step Merger and the other transactions contemplated by the Merger Agreement, including the acquisition by the surviving entity of Complex Networks, are hereinafter referred to as the “Business Combination.” In connection with the consummation of the Business Combination, 890 was renamed “BuzzFeed, Inc.” Liquidity As of and for the year ended December 31, 2021, the Company has cash and cash equivalents of $79.7 million, generated positive income of $25.9 million, and positive operating cash inflows. However, the Company has a history of losses, and has an accumulated deficit of $322.1 million as of December 31, 2021. The Company has cash available on hand and management believes its existing capital resources will be sufficient to support the Company’s operations and meet its obligations as they come due within one year from the date these consolidated financial statements are issued. The Business Combination On the Closing Date: (i) each issued and outstanding share of Class A common stock, par value $0.0001 per share (the “890 Class A common stock”), and Class F common stock, par value $0.0001 per share (the “890 Class F common stock”), of 890 became one share of BuzzFeed Class A common stock, par value $0.0001 per share (the “BuzzFeed Class A common stock”); (ii) each issued and outstanding whole warrant to purchase shares of 890 Class A common stock became a warrant to acquire one share of BuzzFeed Class A common stock at an exercise price of $11.50 per share (each a “BuzzFeed warrant”); and (iii) each issued and outstanding unit of 890 that had not been previously separated into the underlying share of 890 Class A common stock and the underlying warrants of 890 upon the request of the holder thereof was cancelled and entitled the holder thereof to one share of BuzzFeed Class A common stock and one-third of one BuzzFeed warrant. In addition, on the Closing Date (i) each share of Legacy BuzzFeed Class A common stock and Legacy BuzzFeed preferred stock (other than Series F Preferred Stock and Series G Preferred Stock, any cancelled shares or dissenting shares) issued and outstanding were cancelled and automatically converted into the right to receive 0.306 shares of BuzzFeed Class A Common Stock; (ii) all of the shares of Series F Preferred Stock and Series G Preferred Stock issued and outstanding were cancelled and automatically converted into the right to receive 30,880,000 shares of BuzzFeed Class A Common Stock; (iii) each share of Class B Common Stock of Legacy BuzzFeed issued and outstanding (other than any cancelled shares or dissenting shares) were cancelled and automatically converted into the right to receive 0.306 shares of BuzzFeed Class B Common Stock; and (iv) each share of Class C Common Stock of Legacy BuzzFeed issued and outstanding were cancelled and automatically converted into the right to receive 0.306 shares of BuzzFeed Class C Common Stock, in each case in accordance with the applicable provisions of the Merger Agreement. As a result, shares of BuzzFeed capital stock no longer represent an ownership interest in Legacy BuzzFeed, but instead represent an ownership interest in BuzzFeed. In addition, pursuant to subscription agreements entered into in connection with the Merger Agreement, the Company issued, and certain investors purchased, $150.0 million aggregate principal amount of unsecured convertible notes due 2026 concurrently with the closing of the Business Combination (the “Notes”). Holders of 27,133,519 shares of 890 Class A common stock sold in 890’s initial public offering (the “Public Shares”) properly exercised their right to have their public shares redeemed for a full pro rata portion of the trust account holding the proceeds from 890’s initial public offering, calculated as of two The following table summarizes the proceeds raise and issuance costs incurred related to the Business Combination: ​ ​ ​ ​ ​ Cash from reverse recapitalization $ 16,167 890 reverse recapitalization costs ​ (13,795) BuzzFeed reverse recapitalization costs ​ (14,609) Accrued reverse recapitalization costs ​ 585 Net proceeds from reverse recapitalization ​ $ (11,652) ​ ​ ​ ​ Proceeds from Notes ​ $ 150,000 Issuance costs ​ (6,757) Issuance costs settled in stock ​ 563 Proceeds from issuance of Notes, net of issuance costs ​ $ 143,806 ​ After giving effect to the Business Combination (including the issuance of 10,000,000 shares of BuzzFeed Class A common stock pursuant to the C Acquisition Purchase Agreement), the redemption of Public Shares as described above and the separation of the former 890 units, as of the Closing Date, there were 110,789,875 shares of BuzzFeed Class A common stock issued and outstanding outstanding outstanding The Two-Step Merger was accounted for as a reverse recapitalization, with no goodwill or other intangible assets recorded, in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Under this method of accounting, 890 was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the reverse recapitalization was treated as the equivalent of Legacy BuzzFeed issuing stock for the net assets of 890, accompanied by a recapitalization. The net assets of 890 were stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the reverse recapitalization are those of Legacy BuzzFeed. The determination of Legacy BuzzFeed being the accounting acquirer for the Two-Step Merger was primarily based on evaluation of the following facts and circumstances: (i) Legacy BuzzFeed’s existing stockholders own the majority of the shares and have the majority of the voting interests in BuzzFeed with more than 97% of the voting interests; (ii) Legacy BuzzFeed appointed the majority of the directors on BuzzFeed’s Board; (iii) Legacy BuzzFeed’s existing management comprises the majority of the management of BuzzFeed; (iv) Legacy BuzzFeed is the larger entity based on historical revenues and business operations and comprises the majority of the ongoing operations of BuzzFeed; and (v) Legacy BuzzFeed assumed BuzzFeed’s name. In accordance with guidance applicable to these circumstances, the equity structure has been recast in all comparative periods up to the Closing Date to reflect the number of shares of the Company’s common stock, $0.0001 par value per share, issued to Legacy BuzzFeed’s stockholders in connection with the Business Combination. As such, the shares and corresponding capital amounts and earnings per share related to Legacy BuzzFeed redeemable convertible preferred stock (other than Series F Preferred Stock and Series G Preferred Stock ) and Legacy BuzzFeed common stock prior to the Business Combination have been retroactively recast as shares reflecting the Exchange Ratio of 0.306 established in the Business Combination. Legacy BuzzFeed Series F Preferred Stock and Series G Preferred stock have been retroactively restated based on the exchange into 30,880,000 shares of BuzzFeed Class A common stock established in the Business Combination. BuzzFeed common stock and warrants commenced trading on the Nasdaq Stock Market LLC under the symbols “BZFD” and “BZFDW,” respectively, on December 6, 2021. COVID-19 In March 2020, the World Health Organization declared the viral strain of COVID-19 a global pandemic and recommended containment and mitigation measures worldwide. The spread of COVID-19 and the resulting economic contraction has resulted in increased business uncertainty and significantly impacted our business and results of operations. We believe that the COVID-19 pandemic drove a shift in commerce from offline to online, including an increase in online shopping, which we believe contributed to the rapid growth we experienced in our commerce revenue for fiscal 2020. However, the growth of our commerce revenue has decelerated during 2021 as shelter-in-place orders were lifted, consumers returned to shopping in stores, and retailers struggled with supply chain disruptions and labor shortages. The continued duration and severity of the COVID-19 pandemic is uncertain, rapidly changing, and difficult to predict. The degree to which COVID-19-related disruptions impact the Company’s future results will depend on future developments, which are outside of the Company’s control, including, but not limited to, the duration of the pandemic, its severity, the success of actions taken to contain or prevent the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. Our growth rate may continue to be impacted by additional macroeconomic factors beyond our control, such as inflation, retail businesses reopening, increased consumer spending on travel and other discretionary items, and the absence of new U.S. and other government economic stimulus programs, among other things.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Financial Statements and Principles of Consolidation The accompanying consolidated financial statements include the accounts of BuzzFeed, Inc., and its wholly-owned and majority-owned subsidiaries. The Company’s consolidated financial statements are prepared in accordance with GAAP. All intercompany balances and transactions have been eliminated in consolidation. Certain prior year figures have been reclassified to conform to current period presentation. The Company evaluates its relationships with other entities to identify whether they are variable interest entities (“VIE”) in accordance with Accounting Standards Codification (“ASC”) 810, Consolidation. In August 2015, the Company signed a Joint Venture Agreement (“JVA”) with Yahoo Japan to establish and develop operations in Japan. BuzzFeed Japan will carry out the core BuzzFeed business in the Japanese language for the Japanese market. BuzzFeed Japan is a joint venture owned 51% by the Company, through its wholly-owned subsidiaries, BuzzFeed UK Limited, and The Huffington Post Holdings LLC and 24.5% by Z Holdings Corporation and 24.5% by Asahi Shimbun Company. BuzzFeed Japan is included as a consolidated subsidiary in the consolidated financial statements. During 2021 and 2020 the Company established several production companies created solely for the purpose of producing a single film each, which are considered VIEs. The Company is the primary beneficiary of each production company as it has the ability to direct the activities that most significantly impact the economic performance of the entities, the obligation to absorb losses, and the right to receive benefits from the entities. As a result, the production companies are included as consolidated subsidiaries in the consolidated financial statements. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported results of operations during the reporting period. Due to the use of estimates inherent in the financial reporting process actual results could differ from those estimates. Key estimates and assumptions relate primarily to revenue recognition, fair values of intangible assets acquired in business combinations, valuation allowances for deferred income tax assets, allowance for doubtful accounts, fair value of the derivative liability, fair values used for stock-based compensation in periods prior to the Business Combination, useful lives of fixed assets, and capitalized software costs. Fair Value Measurements The fair value framework under the applicable authoritative guidance requires the categorization of assets and liabilities into three levels: ● Level 1 — inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities ● Level 2 — inputs are observable, either directly or indirectly, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. ● Level 3 — inputs are generally unobservable inputs and typically reflect management’s best estimate of assumptions that market participants would use in pricing the asset or liability. The fair value of a financial instrument is the amount for which the instrument could be exchanged in a current transaction between willing parties. The level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest-level input that is significant to the fair value measurement in its entirety. The carrying amounts of cash and cash equivalents, accounts receivable, prepaid and other current assets, accounts payable, accrued expenses, deferred rent, deferred revenue, other current liabilities, and borrowings on our Revolving Credit Facility (as defined below) approximate fair value. Money market funds are categorized as Level 1. The Company’s non-financial assets, which include property and equipment, capitalized software costs, prepaid and other assets, and intangible assets, are not required to be measured at fair value on a recurring basis. However, if certain triggering events occur, or if an annual impairment test is required and the Company is required to evaluate the non-financial asset for impairment, a resulting asset impairment would require that the non-financial asset be recorded at its fair value. Cash and Cash Equivalents and Restricted Cash Financial instruments that potentially subject the Company to concentration of credit risk consist of cash and cash equivalents. The Company considers instruments with an original maturity of three months or less at the date of purchase to be cash equivalents. The Company’s cash and cash equivalents consist of demand deposits with financial institutions and investments in money market funds. Deposits held with these financial institutions may exceed the amount of insurance provided on such deposits. The associated risk of concentration is mitigated by banking with creditworthy institutions. The Company classifies all cash whose use is limited by contractual provisions as restricted cash. In the first quarter of 2021, letters of credit totaling $15.5 million were issued under the $50.0 million revolving credit facility (the “Revolving Credit Facility”) which reduced the remaining borrowing capacity by the same amount. These letters of credit were used in favor of our landlords, relieving us of the requirement to maintain $15.5 million of cash as collateral. As a result, the $15.5 million of restricted cash as of December 31, 2020 is no longer restricted. The following table summarizes cash and cash equivalent and restricted cash in the consolidated balance sheets (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ 2021 2020 Cash and cash equivalents ​ $ 79,733 ​ $ 90,626 Restricted cash ​ — ​ 15,500 Total ​ $ 79,733 ​ $ 106,126 ​ Accounts Receivable and Allowance for Doubtful Accounts The Company’s accounts receivable are customer obligations due under normal trade terms, carried at their face value less an allowance for doubtful accounts if required. The Company determines its allowance for doubtful accounts based on the evaluation of the aging of its accounts receivable and on a customer-by-customer analysis of its high-risk customers. The Company’s reserve contemplates its historical loss rate on receivables, specific customer situations and the economic environments in which the Company operates. The change in the Company’s allowance for doubtful accounts was as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ 2021 2020 2019 Balance as of January 1, ​ $ 1,387 ​ $ 1,122 ​ $ 1,055 Additions ​ 703 ​ 1,208 ​ 449 Write-offs, net of recoveries ​ (996) ​ (943) ​ (382) Balance as of December 31, ​ $ 1,094 ​ $ 1,387 ​ $ 1,122 ​ As of December 31, 2021, the Company had one customer that represents 11% of net accounts receivable. As of December 31, 2020, the Company had four customers that represent 13%, 13%, 12% and 10% of net accounts receivable. The Company had two customers representing 13% and 12% of total revenue for the year ended December 31, 2021, two customers representing 13% and 10% of total revenue for the year ended December 31, 2020, and two customers representing 12% and 10% of total revenue for the year ended December 31, 2019. Film Costs Costs incurred to produce films (which include direct production costs, production overhead, acquisition costs and development costs) are capitalized when incurred. Capitalized film costs are amortized based upon the ratio of current period revenues to estimated total gross revenues to be earned from the film. Film costs, which were included in prepaid and other assets on the consolidated balance sheets, were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 2020 Individual Monetization: ​ ​ ​ ​ ​ ​ Feature films in production ​ $ 3,690 ​ $ 2,086 Total ​ $ 3,690 ​ $ 2,086 ​ During the year ended December 31, 2021, the Company amortized film costs of $7.1 million associated with individually monetized feature films. No amortization of film costs was recorded during the years ended December 31, 2020 or 2019. Film cost amortization is included in cost of revenue in the consolidated statements of operations. Film costs are stated at the lower of amortized cost or estimated fair value and are reviewed on a title-by-title basis when an event or change in circumstances indicates that the fair value of a film is less than its unamortized cost. During the years ended December 31, 2021, 2020 or 2019, the Company recorded no impairment charges related to film costs. Property and Equipment Property and equipment is stated at cost, less accumulated depreciation. Depreciation on property and equipment is calculated using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life. The estimated useful lives of property and equipment of each asset category are as follows: ​ ​ ​ ​ ​ Useful Life (Years) Furniture and fixtures 5 Leasehold improvements 7 – 11 Computer equipment 3 Video equipment 3 ​ Capitalized Software Costs The Company capitalizes certain costs incurred for development of websites or software for internal use. The Company capitalizes development costs when preliminary development efforts are successfully completed, management has authorized and committed project funding and it is probable that the project will be completed and the software will be used as intended. Costs include payroll and payroll-related costs of employees directly associated with the development activities. Costs incurred for enhancements that are expected to result in additional features or functionality are capitalized and amortized over the estimated useful life of the enhancements, generally 1 Investments For equity investments in entities that the Company does not exercise significant influence over, if the fair value of the investment is not readily determinable, the investment is accounted for at cost, and adjusted for subsequent observable price changes. If the fair value of the investment is readily determinable, the investment is accounted for at fair value. The Company reviews equity investments without readily determinable fair values at each period end to determine whether they have been impaired. As of December 31, 2021 and 2020, the Company had an investment in equity securities of a privately-held company without a readily determinable fair value. The total carrying value of the investment, included in prepaid and other assets on the consolidated balance sheets, was $2.3 million as of December 31, 2021 and 2020. The Company concluded that the fair value of the investment increased $0.5 million during the year ended December 31, 2020 as the result of observable price changes in orderly transactions for a similar investment in the same issuer. Evaluation of Long-Lived Assets and Impairment The Company reviews its property and equipment and capitalized software costs for impairment when events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. If circumstances require a long-lived asset to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by the asset to its carrying value. If the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques which may include discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. There was no impairment of long-lived assets for the years ended December 31, 2021, 2020, or 2019. Revenue Recognition The Company recognizes revenue in a manner that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company primarily generates its revenue from advertising services and content, which includes strategic partnerships and promotional content, with the remaining balance from other arrangements, including commerce. Advertising The Company generates its advertising revenue from managing a customer’s internet advertising campaigns to target markets both via BuzzFeed’s proprietary sites as well as premium publishers (e.g., Facebook and Google). Our performance obligations typically consist of a promised number of ads delivered or a promised number of actions related to the ads (such as impressions or views). Advertising revenue is recognized in the period that the related views, impressions, or actions by users on advertisements are delivered. When ads are placed on the Company’s owned and operated or third parties’ properties, the Company generally recognizes revenue on a gross basis because the Company is primarily responsible for the delivery of the promised services, has pricing discretion, and controls the advertising inventory prior to transfer to the customer. In some cases, the Company utilizes third party intermediaries to facilitate the sale of advertising to the end customer. In these situations, while the Company is primarily responsible for the delivery of the promised services and controls the advertising inventory prior to transfer to the end customer, the Company typically does not have insight, and does not expect to have insight, into the gross amount paid by the end customer and therefore records as revenue the net amount received from the intermediary. Content The Company generates revenue from creating content, including promotional content, customer advertising, and feature films. The Company’s performance obligations consist of Company-created content for use by its customers or the delivery of a promised number of actions related to the content (impressions or views). The revenue is recognized when the content, or the related action, is delivered. Commerce The Company participates in multiple marketplace arrangements with third parties such as Amazon whereby the Company provides affiliate links which redirect the audience to purchase products and/or services from the third parties. When the participant purchases a product and/or service, the Company receives a commission fee for that sale from the third parties. The revenue is recognized when a successful sale is made and the commission is earned. Cost of Revenue Cost of revenue consists primarily of compensation-related expenses and costs incurred for the publishing of editorial, promotional, and news content across all platforms, as well as amounts due to third party websites and platforms to fulfil customers’ advertising campaigns. Web hosting and advertising serving platform costs are also included in cost of revenue. Sales and Marketing Sales and marketing expenses consist primarily of compensation-related expenses for sales employees. In addition, marketing and sales-related expenses include advertising costs, market research, and branding. General and Administrative General and administrative expense consists primarily of compensation-related expenses for corporate employees. Also, it consists of expense for facilities, professional services fees, insurance costs, and other general overhead costs. Research and Development Research and development (“R&D”) expenses consist primarily of compensation-related expenses incurred for the development of, enhancements to, and maintenance of the Company’s website, technology platforms and infrastructure. R&D expenses that do not meet the criteria for capitalization are expensed as incurred. Certain development expenses are capitalized under the provisions of the applicable authoritative guidance, whereby the Company capitalizes costs associated with website and internal-use software systems that have reached the application development stage. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded for deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company recognizes tax benefits from uncertain tax positions if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The Company made a policy election to treat the income tax with respect to GILTI as a period expense when incurred. Stock-Based Compensation Stock-based compensation is recognized as an expense in the consolidated financial statements and is measured at the fair value of the award. The Company recognizes compensation expense for stock awards based on grant date fair value using the Black-Scholes option-pricing model. The Company accounts for forfeitures as they occur. The Company adopted Accounting Standards Update (“ASU”) 2018-07, Improvements to Non-employee Share-Based Payment Accounting The following table summarizes stock-based compensation cost included in the consolidated statements of operations: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ 2021 2020 2019 Cost of revenue, excluding depreciation and amortization ​ $ 2,788 ​ $ 109 ​ $ 353 Sales and marketing ​ 4,829 ​ 60 ​ 658 General and administrative ​ 15,052 ​ 977 ​ 1,446 Research and development ​ 896 ​ 43 ​ 356 ​ ​ $ 23,565 ​ $ 1,189 ​ $ 2,813 ​ The Company recognized no income tax benefit in the consolidated statements of operations for stock-based compensation arrangements in 2021, 2020 or 2019. Comprehensive Income (Loss) Comprehensive income (loss) includes certain changes in stockholders’ equity that are excluded from net income (loss) such as cumulative foreign currency translation adjustments, unrealized gains or losses on marketable securities, and comprehensive income (loss) attributed to the redeemable noncontrolling interest. Foreign Currency The functional currency of our foreign subsidiaries are generally the local currency. The financial statements of these subsidiaries are translated into U.S. dollars using month-end rates of exchange for assets and liabilities, and average rates of exchange for revenue, costs and expenses. Translation gains and losses are recorded in accumulated other comprehensive loss in stockholders’ equity. Transaction gains and losses including intercompany transactions denominated in a currency other than the functional currency of the entity involved are included in foreign exchange gain (loss) within other income, net in the consolidated statements of operations. The Company does not enter into foreign currency forward exchange contracts or other derivative financial instruments to hedge the effects of adverse fluctuations in foreign currency exchange rates. Recently Adopted Accounting Pronouncements The Company, an emerging growth company, or EGC, has elected to take advantage of the benefits of the extended transition period provided for in Section 7(a)(2)(B) of the Securities Act, for complying with new or revised accounting standards which allows the Company to defer adoption of certain accounting standards until those standards would otherwise apply to private companies. In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40), Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity retrospective transition method. The Company elected to early adopt ASU 2020-06 effective January 1, 2021. The adoption of ASU 2020-06 did not have a significant impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other (Topic 350): Internal-Use Software On January 1, 2020, the Company adopted ASU 2018-13, Fair Value Measurement (Topic 820) — Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement On January 1, 2021, the Company adopted the amended guidance in ASU 2019-02, Improvements to Accounting for Costs of Films and License Agreements for Program Materials On January 1, 2019, the Company adopted Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) Accounting Pronouncements Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes

Acquisitions and Dispositions C Acquisition On December 3, 2021, the Company completed the acquisition of 100% of the members’ interests of Complex Networks, a publisher of online media content targeting Millennial and Gen Z consumers (the “C Acquisition”). The following table summarizes the fair value of consideration exchanged as a result of the C Acquisition: ​ ​ ​ ​ ​ Cash consideration (1) $ 197,966 Share consideration (2) ​ 96,200 Total consideration ​ $ 294,166 (1) Includes the cash purchase price of $200.0 million adjusted for certain closing specified liabilities as specified in the C Acquisition Purchase Agreement. (2) Represents 10,000,000 shares of BuzzFeed Class A common stock at a price of $9.62 per share, which is based on the Company’s closing stock price for Class A common stock on the Closing Date. The following table summarizes the preliminary determination of the fair value of identifiable assets acquired and liabilities assumed from the C Acquisition. The purchase price allocation for the assets acquired and liabilities assumed may be subject to change as additional information is obtained during the acquisition measurement period. ​ ​ ​ ​ Cash 2,881 Accounts receivable 22,581 Prepaid and other current assets 17,827 Property and equipment 332 Intangible assets 119,100 Goodwill 189,391 Accounts payable (2,661) Accrued expenses (12,319) Accrued compensation (12,867) Deferred revenue (5,855) Deferred tax liabilities (22,776) Other liabilities (1,468) Total consideration for Complex Networks 294,166 ​ The table below indicates the estimated fair value of each of the identifiable intangible assets: ​ ​ ​ ​ ​ ​ ​ ​ Weighted Average ​ ​ Asset Fair Value ​ Useful Life (Years) Trademarks & tradenames 97,000 15 Customer relationships 17,000 4 Developed technology 5,100 3 ​ The fair values of the intangible assets were estimated using Level 3 inputs. The fair value of trademarks and trade names was determined using the relief from royalty method, the fair value of customer relationships was determined using the multi-period excess earnings approach, and the fair value of acquired technology was determined using the replacement cost approach. The excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired resulted in $189.4 million of goodwill, which is primarily attributed to workforce and synergies, and is not deductible for tax purposes. The C Acquisition contributed $18.5 million of revenue and $1.2 million of net income for the year ended December 31, 2021. Pro Forma Financial Information The following unaudited pro forma information has been presented as if the C Acquisition occurred on January 1, 2020. The information is based on the historical results of operations of Complex Networks, adjusted for: 1. 2. 3. 4. 5. The pro forma results do not necessarily represent what would have occurred if the C Acquisition had taken place on January 1, 2020, nor do they represent the results that may occur in the future. The pro forma adjustments were based on available information and upon assumptions that the Company believes are reasonable to reflect the impact of these acquisitions on the Company’s historical financial information on a supplemental pro forma basis. The following table presents the Company’s pro forma combined revenues and net income. ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ ​ 2021 2020 Revenue ​ $ 521,224 ​ $ 446,368 Net loss ​ (19,747) ​ (12,972) ​ Acquisition of HuffPost and Verizon Investment On February 16, 2021, the Company completed the acquisition of 100% of TheHuffingtonPost.com, Inc. (“HuffPost”) (“HuffPost Acquisition”), a publisher of online news and media content, from entities controlled by Verizon Communications Inc. (“Verizon”). The Company issued 6,478,032 shares of non-voting BuzzFeed Class C common stock to an entity controlled by Verizon, of which 2,639,322 were in exchange for the acquisition of HuffPost and 3,838,710 were in exchange for a concurrent $35.0 million cash investment in the Company by Verizon, which was accounted for as a separate transaction.

During the year ended December 31, 2021, the Company finalized the fair value of assets acquired and liabilities assumed. Measurement period adjustments were reflected in the fourth quarter of 2021, which is the period in which the adjustments occurred. The adjustments resulted from deferred income tax adjustments. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Measurement ​ ​ ​ ​ ​ ​ ​ Period ​ ​ ​ ​ ​ Preliminary ​ Adjustments ​ Final Cash and cash equivalents ​ 5,513 ​ — ​ 5,513 Accounts receivable ​ 3,383 ​ — ​ 3,383 Prepaid and other current assets ​ 611 ​ — ​ 611 Deferred tax assets ​ 116 ​ 15 ​ 131 Property and equipment ​ 620 ​ — ​ 620 Intangible assets ​ 19,500 ​ — ​ 19,500 Goodwill ​ 5,927 ​ (437) ​ 5,490 Accounts payable ​ (1,410) ​ — ​ (1,410) Accrued expenses ​ (4,249) ​ — ​ (4,249) Deferred tax liabilities ​ (4,251) ​ 422 ​ (3,829) Other liabilities ​ (63) ​ — ​ (63) Noncontrolling interests ​ (2,123) ​ — ​ (2,123) Total consideration for HuffPost ​ $ 23,574 ​ $ — ​ $ 23,574 ​ The fair values of the intangible assets were estimated using Level 3 inputs. The fair value of trademarks and trade names was determined using the relief from royalty method and the fair value of acquired technology was determined using the replacement cost approach. The useful lives of the acquired trademarks and trade names and acquired technology are 15 years and 3 years, respectively. The excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired resulted in $5.5 million of goodwill, which is primarily attributed to workforce and synergies, and is not deductible for tax purposes. The HuffPost Acquisition contributed $30.3 million of revenue for the year ended December 31, 2021. The HuffPost Acquisition did not have a material impact on the Company’s net loss for the year ended December 31, 2021. Dispositions of HuffPost Italy, HuffPost Korea and HuffPost France During 2021 the Company disposed of its 51% ownership interests in HuffingtonPost Italia S.R.L (“HuffPost Italy”), HuffingtonPost Korea, Ltd. (“HuffPost Korea”), and Le HuffingtonPost SAS (“HuffPost France”) for nominal consideration and recognized losses on disposition of $1.2 million. HuffPost Italy, HuffPost Korea, and HuffPost France did not have a material impact on the Company’s net loss for the year ended December 31, 2021. Disposition of BuzzFeed Brazil In October 2020 the Company completed the sale of 100% ownership of BuzzFeed do Brasil Internet Ltda.

The payment terms and conditions within the Company’s contracts vary by the type, the substantial majority of which require that customers pay for their services on a monthly or quarterly basis, as the services are being provided. When the timing of revenue recognition differs from the timing of payments made by customers, the Company recognizes either unbilled revenue (its performance precedes the billing date) or deferred revenue (customer payment is received in advance of performance).

The Company’s warrant liability as of December 31, 2021 includes public and private warrants that were originally issued by 890, but which were assumed by the Company as part of the Closing of the Business Combination (the “Public Warrants” and “Private Warrants”, respectively, or together, the “Public and Private Warrants”). The Public and Private Warrants are recorded on the balance sheet at fair value. The carrying amount is subject to remeasurement at each balance sheet date. With each remeasurement, the carrying amount is adjusted to fair value, with the change in fair value recognized in the Company’s consolidated statements of operations and comprehensive loss. The Public Warrants are publicly traded under the symbol “BZFDW”, and the fair value of the Public Warrants at a specific date is determined by the closing price of the Public Warrants as of that date. As such, the Public Warrants are classified within Level 1 of the fair value hierarchy. The closing price of the Public Warrants was $0.98 and $0.50 as of December 3, 2021 and December 31, 2021, respectively. As of December 31, 2021, Level 3 instruments consisted of the Company’s derivative liability related to the Notes. Fair value measurements categorized within Level 3 are sensitive to changes in the assumptions or methodologies used to determine fair value, and such changes could result in a significant increase or decrease in the fair value. To measure the fair value of the derivative liability, the Company compared the calculated value of the Notes with the indicated value of the host instrument, defined as the straight-debt component of the Notes. The difference between the value of the straight-debt host instrument and the fair value of the Notes resulted in the value of the derivative liability. The value of the straight-debt host instrument was estimated based on a binomial lattice model, excluding the conversion option and the make-whole payment upon conversion. The following table provides quantitative information regarding the significant unobservable inputs used by the Company related to the derivative liability: ​ ​ ​ ​ ​ ​ ​ ​ December 31, December 3, ​ 2021 2021 Term (in years) 4.9 5.0 ​ Risk-free rate 1.25 % 1.13 % Volatility 31.5 % 28.0 % ​ The following table represents the activity of the Level 3 instruments: ​ ​ ​ ​ ​ ​ Derivative ​ ​ Liability Balance as of December 31, 2020 ​ ​ — Issuance of Notes ​ $ 31,620 Change in fair value of derivative liability ​ (26,745) Balance as of December 31, 2021 ​ $ 4,875 ​ There were no transfers between fair value measurement levels during the year ended December 31, 2021.

Debt
Debt	9. Debt Secured Facility On May 20, 2020, the Company entered into a two-year, $20.0 million, secured borrowing facility agreement (“Secured Facility”). Borrowings under the Secured Facility were limited to 80% of qualifying accounts receivable and bore interest at a rate of LIBOR plus 7.25% per annum, subject to a LIBOR floor rate of 1.5%. Repayment of borrowings under the Secured Facility was required upon the earlier of: (i) the collection of the qualified account receivable, (ii) the maturity date of May 21, 2022, or (iii) on demand with respect to any qualified account receivable that is disputed by the payor, for which the payor has become insolvent or has indicated an inability or unwillingness to pay, or that remains uncollected more than 120 days from the original invoice date. The Secured Facility was subject to a minimum monthly average utilization of $10.0 million. Borrowings under the Secured Facility were collateralized by the Company’s personal property (including accounts receivable but excluding intellectual property). The Secured Facility included covenants that, among other things, limited the ability of the Company to incur additional indebtedness. The Company terminated the Secured Facility on December 30, 2020. Revolving Credit Facility On December 30, 2020, the Company entered into a new three-year, $50.0 million, revolving loan and standby letter of credit facility agreement (“Revolving Credit Facility”). The Revolving Credit Facility provides for the issuance of up to $15.5 million of standby letters of credit and aggregate borrowings under the Revolving Credit Facility are generally limited to 95% of qualifying investment grade accounts receivable and 90% of qualifying non-investment grade accounts receivable, subject to adjustment at the discretion of the lenders. The Revolving Credit Facility includes covenants that, among other things, require the Company to maintain at least $25.0 million of unrestricted cash at all times, limits the ability of the Company to incur additional indebtedness, pay dividends, hold unpermitted investments, or make material changes to the business. The Company was in compliance with the financial covenant as of December 31, 2021. The $15.5 million of standby letters of credit were issued during the three months ended March 31, 2021 in favor of certain of the Company’s landlords. The Revolving Credit Facility was amended and restated in connection with the closing of the Business Combination, namely to, among other things, add the Company and certain other entities as guarantors. Borrowings under the Revolving Credit Facility bear interest at LIBOR, subject to a floor rate of 0.75%, plus a margin of 3.75% to 4.25%, depending on the level of the Company’s utilization of the facility (4.50% at December 31, 2021), and subject to a monthly minimum utilization of $15.0 million. The facility also includes an unused commitment fee of 0.375%. As of December 31, 2021, the Company had outstanding borrowings of $28.5 million under the Revolving Credit Facility and $15.5 million of outstanding letters of credit issued under the facility. As of December 31, 2020, the Company had outstanding borrowings of $20.4 million and no letters of credit outstanding. The total unused borrowing capacity was $5.4 million and $29.6 million as of December 31, 2021 and 2020, respectively. As of December 31, 2021 and 2020, the Company had $0.3 million and $0.5 million of costs in connection with the issuance of debt included in prepaid and other assets in the consolidated balance sheet, respectively. ​ Convertible Notes In June 2021, the Company entered into subscription agreements with certain purchasers to sell $150.0 million aggregate principal amount of unsecured convertible notes due 2026. In connection with the Business Combination, the Company completed the Convertible Note Financing of $150.0 million of unsecured convertible notes. The Notes bear interest at a rate of 8.50% per annum, payable semi-annually. The Notes are convertible into shares of Class A common stock, or a combination of cash and Class A common stock, at the Company’s election, at an initial conversion price of $12.50 and mature on December 3, 2026. The Company may, at its election, force conversion of the Notes after the third anniversary of the issuance of the Notes, subject to a holder’s prior right to convert and certain other conditions, if the volume-weighted average trading price of the BuzzFeed Class A common stock is greater than or equal to 130% of the conversion price for more than 20 trading days during a period of 30 consecutive trading days. In the event that a holder of the Notes elects to convert its Notes after the one year anniversary, and prior to the three-year anniversary, of the issuance of the Notes, the Company will be obligated to pay an amount equal to: (i) from the one year anniversary of the issuance of the Notes to the two year anniversary of the issuance of the Notes, an amount equal to 18 month’s interest declining ratably on a monthly basis to 12 month’s interest on the aggregate principal amount of the Notes so converted and (ii) from the two year anniversary of the issuance of the Notes to the three year anniversary of the issuance of the Notes, an amount equal to 12 month’s interest declining ratably on a monthly basis to zero month’s interest, in each case, on the aggregate principal amount of the note so converted (the “Interest Make-Whole Payment”). The Interest Make-Whole Payment will be payable in cash. Without limiting a holder’s right to convert the Notes at its option, interest will cease to accrue on the Notes during any period in which the Company would otherwise be entitled to force conversion of the Notes, but is not permitted to do so solely due to the failure of a trading volume condition specified in the indenture governing the Notes. Each holder of a Note will have the right to cause the Company to repurchase for cash all or a portion of the Notes held by such holder (i) at any time after the third anniversary of the closing date, at a price equal to par plus accrued and unpaid interest; or (ii) at any time upon the occurrence of a fundamental change (as defined in the indenture governing the Notes), at a price equal to 101% of par plus accrued and unpaid interest. The indenture governing the Notes includes restrictive covenants that, among other things, limit the Company’s ability to incur additional debt or liens, make restricted payments or investments, dispose of significant assets, transfer intellectual property, or enter into transactions with affiliates. In accounting for the Notes, the Company bifurcated a derivative liability representing the conversion option, with a fair value at issuance of $31.6 million. To measure the fair value of the derivative liability, the Company compared the calculated value of the Notes with the indicated value of the host instrument, defined as the straight-debt component of the Notes. The difference between the value of the straight-debt host instrument and the fair value of the Notes resulted in the value of the derivative liability. The value of the straight-debt host instrument was estimated based on a binomial lattice model, excluding the conversion option and the make-whole payment upon conversion. The derivative liability is remeasured at each reporting date with the resulting gain or loss recorded in Change in fair value of derivative liability within the consolidated statements of operations. Debt issuance costs related to the Notes totaled $6.7 million and were allocated between the debt component and derivative liability based on their relative values. Issuance costs attributable to the debt component were $5.3 million and will be amortized to interest expense using the effective interest method over the contractual term. Issuance costs attributable to the derivative liability were $1.4 million and were expensed immediately. Interest expense on the Notes is recognized at an effective interest rate of 15% and totaled $1.3 million for the year ended December 31, 2021, of which amortization of the debt discount and issuance costs comprised $0.3 million. The net carrying amount of the Notes as of December 31, 2021 was: ​ ​ ​ ​ ​ Principal outstanding $ 150,000 Unamortized debt discount and issuance costs ​ (36,627) Balance as of December 31, 2021 ​ $ 113,373 ​ The fair value of the Notes as of December 31, 2021 was approximately $126.0 million. The fair value of the Notes was estimated using Level 3 inputs.

Warrants
Warrants	10. Warrants In connection with the closing of the Business Combination, the Company assumed 9,583,287 Public Warrants and 292,500 Private Warrants. The Company accounts for the warrants assumed as in accordance with the guidance contained in Derivatives and Hedging  —  Contracts in Entity’s Own Equity (ASC 815-40). Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a liability. Accordingly, the Company classifies each warrant as a liability at its fair value. This liability is subject to re-measurement at each balance sheet date. With each such remeasurement, the warrant liability is adjusted to fair value, with the change in fair value recognized in our consolidated statements of operations. The Public Warrants are exercisable commencing 30 days after the completion of the Business Combination, provided that the Company has an effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the Public Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their Public Warrants on a cashless basis and such cashless exercise is exempt from registration under the Securities Act). The warrants have an exercise price of $11.50 per whole share, subject to adjustments, and will expire five years after the completion of the Business Combination or earlier upon redemption or liquidation. The Private Warrants are identical to the Public Warrants, except that the Private Placement Warrants and the shares of Class A common stock issuable upon exercise of the Private Warrants will not be transferable, assignable or saleable until 30 days after the completion of the Business Combination, subject to certain limited exceptions. Additionally, the Private Warrants are non-redeemable so long as they are held by 890’s sponsor or its permitted transferees. If the Private Warrants are held by someone other than 890’s sponsor or its permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

There were no issued Stock-Based Compensation Stock Incentive Plans The Company’s 2008 Stock Plan (the “2008 Plan”) was adopted on June 25, 2008. The Company’s 2015 Equity Incentive Plan (“2015 Plan”) was adopted on October 30, 2015 and superseded the 2008 plan. The 2015 Plan increased the number of Legacy BuzzFeed shares available for grant and issuance to 16,895,765. The 2015 Plan allowed for the grant of incentive and nonqualified stock options, restricted stock units (“RSUs”), and stock appreciation rights to eligible participants. On October 16, 2018, the 2015 Plan was amended to increase the maximum number of shares of Legacy BuzzFeed common stock available for issuance by 15,700,000. At the time the Equity Incentive Plan (defined below) became effective, 32,595,765 shares of Legacy BuzzFeed common stock had been authorized for issuance under the 2015 Plan. From and after the effectiveness of the Equity Incentive Plan, no additional awards will be granted under the 2015 Plan. Upon the closing of the Business Combination, all outstanding Legacy BuzzFeed stock options under the 2015 Plan and 2008 Plan, whether vested or unvested, were substituted and converted into options to purchase shares of Class A common stock granted in accordance with the Equity Inventive Plan based on the exchange ratio of 0.306. All outstanding Legacy BuzzFeed RSUs under the 2015 Plan and 2008 Plan were substituted and converted into RSUs representing the opportunity to be issued shares of Class A common stock granted in accordance with the Equity Incentive Plan based on the exchange ratio of 0.306. In December 2021, the Equity Incentive Plan was adopted by the 890 board and approved by the 890 stockholders prior to closing of the Business Combination and it became effective on the closing of the Business Combination. The Equity Incentive Plan allows the Company to grant awards of stock options, restricted stock awards, stock appreciation rights (“SARs”), RSUs, cash awards, performance awards, and stock bonus awards to officers, employees, directors and consultants. A total of 31,206,550 shares of Class A common stock were reserved for issuance under the Equity Incentive Plan. The number of shares reserved for issuance under the Equity Incentive Plan will increase automatically on January 1 of each year from 2022 through 2031 by the number of shares equal to the lesser of 5% of the total number of outstanding shares of all classes of common stock as of the immediately preceding December 31, or a number as may be determined by the board of directors.

The fair value of stock option awards is estimated on the date of grant using the Black-Scholes option-pricing model based upon the following range of assumptions: ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 2020 (1) 2019 (1) Exercise price ​ $8.99 – $9.25 ​ $7.48 – $8.33 ​ $8.30 – $8.33 Expected dividend yield ​ 0% ​ 0% ​ 0% Expected volatility ​ 45% – 48% ​ 41% – 46% ​ 38% – 39% Expected term (years) ​ 5.00   6.07 ​ 5.55   6.07 ​ 5.80   6.09 Risk free interest rate ​ 0.80% – 1.04% ​ 0.26% – 1.17% ​ 1.58% – 2.35% (1) Exercise prices have been retroactively adjusted to give effect to the exchange ratio of 0.306. The Company uses the simplified method in accordance with the applicable authoritative guidance to estimate the expected term of the option, due to the limited historical experience to date. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Since the Company’s common stock is not publicly traded for a sufficient time period, the expected volatility is based on expected volatilities of similar companies that have a history of being publicly traded. No dividends have been assumed. The Company records stock-based compensation expense on a straight-line basis over the vesting period. As of December 31, 2021, the total share-based compensation costs not yet recognized related to unvested stock options was $2.2 million, which is expected to be recognized over the weighted-average remaining requisite service period of 1.3 years. The weighted average fair value of stock options granted during December 31, 2021, 2020 and 2019 was $1.23, $1.03, and $1.01 respectively. The intrinsic value of stock options exercised was $13.8 million, $0.4 million, and $1.6 million for the years ended December 31, 2021, 2020 and 2019, respectively. Restricted Stock Units A summary of RSU activity is presented below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted Average ​ ​ ​ ​ Grant-Date Fair ​ Shares (1) Value (1) Outstanding as of December 31, 2020 2,530 ​ $ 8.53 Granted 3,011 ​ 9.11 Vested (4) ​ 9.25 Forfeited (302) ​ 8.33 Outstanding as of December 31, 2021 5,235 ​ $ 8.88 (1) Shares and weighted average grant-date fair value have been retroactively adjusted to give effect to the exchange ratio of 0.306. As of December 31, 2021, there was approximately $29.1 million of unrecognized compensation costs related to RSUs. Included in the above are 2.5 million RSUs that vest based on service and upon the occurrence of a sale transaction (“Acquisition”) or the completion of an initial public offering. The Two-Step Merger did not result in the satisfaction of this liquidity condition as it does not meet the definition of an Acquisition per the award agreements. Unrecognized compensation costs related to these RSUs totaled $21.2 million at December 31, 2021. The closing of the Two-Step Merger satisfied the liquidity condition in 2.7 million RSUs. As a result, $16.0 million of compensation cost associated with service rendered prior to the Two-Step Merger was recognized at Closing. $2.2 million, $4.4 million, $8.7 million, and $0.8 million of this was reflected in cost of revenue, excluding depreciation and amortization, sales and marketing, general and administrative, and research and development within the consolidated statement of operations, respectively. Escrowed Shares In connection with the Business Combination, our Chief Executive Officer and Founder, Jonah Peretti, Jonah Peretti, LLC, NBCUniversal Media, LLC (“NBCU”) and PNC Bank National Association, entered into an escrow agreement (the “Escrow Agreement”). The Escrow Agreement provides for, among other things, the escrow of 1,200,000 shares of New BuzzFeed Class A common stock or New BuzzFeed Class B common stock (the “Escrowed Shares”) exchangeable by Jonah Peretti, LLC in connection with the Two-Step Merger. Pursuant to the Escrow Agreement, in the event the Transfer Date SPAC Share Price (as defined in the Escrow Agreement) is less than $12.50 per share on the Transfer Date (as defined in the Escrow Agreement), Jonah Peretti, LLC and NBCU shall instruct the escrow agent to transfer (1) to NBCU a number of Escrowed Shares equal to the Make Whole Shares (as defined in the Escrow Agreement) and (2) to Mr. Peretti, the remainder of the Escrowed Shares, if any. If the Transfer Date SPAC Share Price is equal to or greater than $12.50 on the Transfer Date, Jonah Peretti, LLC and NBCU shall instruct the escrow agent to transfer all of the Escrowed Shares to Mr. Peretti. The Escrow Agreement was accounted for as a compensatory stock-based compensation award with a market condition. As there are no future service conditions, the $5.4 million fair value of the award was recognized within general and administrative expense at the time of closing of the Business Combination. The fair value was estimated using a model based on multiple stock price paths developed through the use of a Monte Carlo simulation that incorporates into the valuation the likelihood that the market condition will be satisfied.

Earnings (Loss) Per Share
Earnings (Loss) Per Share	14. Net Income (Loss) Per Share Net income (loss) per share is computed using the two-class method. Basic net income (loss) per share is computed using the weighted average number of shares of common stock outstanding for the period. Diluted net income (loss) per share reflects the effect of the assumed exercise of stock options, the vesting of restricted stock units, the exercise of warrants, the conversion of the Notes, and the conversion of convertible preferred stock only in the periods in which such effect would have been dilutive. Undistributed earnings were allocated to convertible preferred stock and shares of Class A common stock, Class B common stock, and Class C common stock based on the contractual participation rights of each as if earnings for the year had been distributed. Holders of convertible preferred stock were entitled to noncumulative annual dividends at a rate of 8% of the applicable original issue price when, as and if declared by the Company’s board of directors and prior to and in preference of payment of dividends on the Company’s common stock. Thereafter, dividends were distributed among holders of Class A common stock, Class B common stock and convertible preferred stock on a proportionate basis, based on the number of shares of common stock that would be held by each holder if all shares of convertible preferred stock were converted to Class B common stock at the then effective conversion rate. Holders of convertible preferred stock did not participate in losses and, accordingly, losses for the year ended December 31, 2019 were allocated entirely to holders of Class A, Class B, and Class C common stock. For the years ended December 31, 2021, 2020, and 2019, net loss per share amounts were the same for Class A, Class B, and Class C common stock because the holders of each class are entitled to equal per share dividends.

The Company recorded excess deferred tax liabilities related to the business combinations which provided a source of future taxable income to support partial realization of the Company’s pre-existing deferred tax assets. The income tax benefit related to the change in valuation allowance was offset by an income tax provision for foreign taxes. For the years ended December 31, 2020 and 2019, the Company’s effective tax rate differed from the U.S. federal statutory income tax rate of 21% primarily due to a valuation allowance against net deferred tax assets that were not realizable on a more-likely-than-not basis. On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act. The CARES Act included several measures to assist companies including temporary changes to income and non-income based tax laws. Several significant tax-related provisions of the CARES Act included (1) allowing net operating loss (NOL) carryforwards originating in 2018, 2019 or 2020 to be carried back to the prior five tax years, (2) eliminating the 80% taxable income limitation by allowing corporate entities to fully utilize NOL carryforwards to offset taxable income in 2018, 2019 or 2020, (3) increasing the net interest expense deduction limitation to 50% of adjusted taxable income from 30% for the 2019 and 2020 tax years, (4) allowing taxpayers with alternative minimum tax credits to claim a refund in 2020 for the entire amount of the credit instead of recovering the credit through refunds over a period of years and (5) allowing companies to deduct more of their cash charitable contributions paid during calendar year 2020 by increasing the taxable income limitation to 25% from 10%. The income tax provisions of the CARES Act had limited applicability to the Company and did not have a material impact on the Company’s consolidated financial statements. Significant components of deferred tax assets and liabilities as of were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ 2021 2020 Deferred tax assets ​ ​ ​ ​ ​ ​ Net operating loss carryforwards ​ $ 93,592 ​ $ 79,475 Accruals ​ 3,503 ​ 2,879 Stock-based compensation ​ 6,380 ​ 2,841 Bad debt ​ 241 ​ 262 Deferred rent ​ 4,167 ​ 5,043 Interest expense ​ ​ 735 ​ ​ ​ Other ​ 691 ​ 1,185 Total deferred tax asset ​ $ 109,309 ​ $ 91,685 Valuation allowance ​ (66,848) ​ (83,978) Net deferred tax asset ​ $ 42,461 ​ $ 7,707 ​ ​ ​ ​ ​ ​ ​ Deferred tax liabilities ​ ​ ​ ​ ​ ​ Deferred state income tax ​ (1,596) ​ (2,087) Depreciation and amortization ​ (1,905) ​ (1,720) Intangible assets ​ (37,352) ​ (3,905) Total deferred tax liability ​ $ (40,853) ​ $ (7,712) Net deferred tax asset (liability) ​ $ 1,608 ​ $ (5) ​ Net deferred tax assets are included within prepaid and other assets and net deferred tax liabilities are included within other liabilities on the Company’s consolidated balance sheets. In assessing the realizability of its deferred tax assets, the Company considered whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Based upon the weight of available evidence, the Company concluded it is more likely than not that it will not be able to realize its U.S. deferred tax assets and therefore has maintained a full valuation allowance on its U.S. deferred tax assets. In addition, the Company maintains a valuation allowance against certain deferred tax assets in the UK, Spain, Japan and Canada. The Company’s valuation allowance decreased by approximately As of December 31, 2021, the Company has U.S. federal and state net operating losses of approximately $314.5 million and $11.3 million, respectively. Of the $314.5 million of U.S. federal net operating losses, $201.5 million expire in tax year beginning 2030 through 2039 if not utilized and $113.0 that has an indefinite lived carryforward period. The million of state net operating losses will expire in tax years beginning in 2025 to 2041 if not utilized. As of December 31, 2021, the Company has foreign net operating loss carryforwards of As of December 31, 2021, the Company has deferred interest expense carryforwards under IRC Section 163(j) of $3.2 million which may be carried forward indefinitely but only available to offset 30% of tax adjusted EBIT. In addition, the Company had federal research and development tax credits of approximately $8.1 million, which expire in the tax years beginning in 2032 through 2041, if not utilized. Notwithstanding the current taxation of certain foreign subsidiaries under GILTI and one-time transition taxation enacted as part of the Tax Cut and Jobs Act, the Company intends to continue to reinvest its foreign earnings indefinitely outside the U.S. If these future earnings are repatriated to the U.S., or if the Company determines that such earnings will be remitted in the foreseeable future, the Company may be required to accrue U.S. deferred taxes (if any) and applicable withholding taxes. It is not practicable to estimate the tax impact of the reversal of the outside basis difference, or the repatriation of cash due to the complexity of its hypothetical calculation. The Company applies the applicable authoritative guidance which prescribes a comprehensive model in which a company should recognize, measure, present and disclose in its financial statements all material uncertain tax positions that the Company has taken or expects to take on a tax return. The Company recognizes interest and penalties related to income tax positions taken on the Company’s tax returns in income tax expense in the consolidated statements of operations. As of December 31, 2021, the Company recorded an uncertain tax position of $nil including interest and penalties related to state taxes. As of December 31, 2020 and 2019, the Company had no uncertain tax positions. The Company, or one of its subsidiaries, files its tax returns in the U.S. and certain state and foreign income tax jurisdictions with varying statute of limitations.

The Company’s lease agreements generally do not contain any material residual value guarantees or material restrictive covenants. Certain of the Company’s lease agreements include escalating lease payments. Additionally, certain lease agreements contain renewal provisions and other provisions which require the Company to pay taxes, insurance, or maintenance costs. Rent expense for the years ended December 31, 2021, 2020 and 2019 were $18.5 million, $25.7 million and $24.8 million respectively. Future minimum lease payments under leases having initial or remaining non-cancelable lease terms in excess of one year as of December 31, 2021 are as follows: ​ ​ ​ ​ Year Amount 2022 ​ $ 33,817 2023 ​ 31,910 2024 ​ 23,885 2025 ​ 21,148 2026 ​ 8,441 Thereafter ​ 2,642 ​ ​ $ 121,843 ​ The Company subleases certain leased office space to third parties when it determines there is excess leased capacity. Sublease rent income is recognized as an offset to rent expense on a straight-line basis over the lease term. In addition to sublease rent, other costs such as common-area maintenance, utilities, and real estate taxes are charged to subtenants over the duration of the lease for their proportionate share of these costs. Sublease income for the years ended December 31, 2021, 2020 and 2019 were $6.8 million, $6.1 million and $2.7 million respectively. Sublease receipts to be received in the future under noncancelable sublease as of December 31, 2021 are as follows: ​ ​ ​ ​ ​ Year Amount 2022 ​ $ 6,769 2023 ​ 6,940 2024 ​ 7,280 2025 ​ 7,360 2026 ​ 2,929 Thereafter ​ 215 ​ ​ $ 31,493 ​ Guarantees In September 2018, at the time of its equity investment in a private company, the Company agreed to guarantee the lease of the investee’s premises in New York. In October 2020, the investee renewed its lease agreement, and the Company’s prior guarantee was replaced with a new guarantee of up to $5.4 million. The amount of the guarantee is reduced as the investee makes payments under the lease. As of December 31, 2021, the maximum amount of the guarantee was $2.7 million, and no liability was recognized with respect to the guarantee. In the course of business, the Company both provides and receives indemnities which are intended to allocate certain risks associated with business transactions. Similarly, the Company may remain contingently liable for various obligations of a business that has been divested in the event that a third party does not fulfill its obligations under an indemnification obligation. The Company records a liability for indemnification obligations and other contingent liabilities when probable and reasonably estimable. Legal Matters The Company is party to various lawsuits and claims in the ordinary course of business. Although the outcome of such matters cannot be predicted with certainty and the impact that the final resolution of such matters will ultimately have on the Company’s consolidated financial statements is not known, we do not believe that the resolution of these matters will have a material adverse effect on the Company’s future results of operations or cash flows. The Company settled or resolved certain legal matters during the fiscal years ended December 31, 2021, 2020 and 2019 that did not individually or in the aggregate have a material impact on the Company’s business or its consolidated financial position, results of operations or cash flows.

The Company’s consolidated financial statements are prepared in accordance with GAAP. All intercompany balances and transactions have been eliminated in consolidation. Certain prior year figures have been reclassified to conform to current period presentation. The Company evaluates its relationships with other entities to identify whether they are variable interest entities (“VIE”) in accordance with Accounting Standards Codification (“ASC”) 810, Consolidation. In August 2015, the Company signed a Joint Venture Agreement (“JVA”) with Yahoo Japan to establish and develop operations in Japan. BuzzFeed Japan will carry out the core BuzzFeed business in the Japanese language for the Japanese market. BuzzFeed Japan is a joint venture owned 51% by the Company, through its wholly-owned subsidiaries, BuzzFeed UK Limited, and The Huffington Post Holdings LLC and 24.5% by Z Holdings Corporation and 24.5% by Asahi Shimbun Company. BuzzFeed Japan is included as a consolidated subsidiary in the consolidated financial statements. During 2021 and 2020 the Company established several production companies created solely for the purpose of producing a single film each, which are considered VIEs. The Company is the primary beneficiary of each production company as it has the ability to direct the activities that most significantly impact the economic performance of the entities, the obligation to absorb losses, and the right to receive benefits from the entities. As a result, the production companies are included as consolidated subsidiaries in the consolidated financial statements.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported results of operations during the reporting period. Due to the use of estimates inherent in the financial reporting process actual results could differ from those estimates. Key estimates and assumptions relate primarily to revenue recognition, fair values of intangible assets acquired in business combinations, valuation allowances for deferred income tax assets, allowance for doubtful accounts, fair value of the derivative liability, fair values used for stock-based compensation in periods prior to the Business Combination, useful lives of fixed assets, and capitalized software costs.
Fair Value Measurements	Fair Value Measurements The fair value framework under the applicable authoritative guidance requires the categorization of assets and liabilities into three levels: ● Level 1 — inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities ● Level 2 — inputs are observable, either directly or indirectly, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. ● Level 3 — inputs are generally unobservable inputs and typically reflect management’s best estimate of assumptions that market participants would use in pricing the asset or liability. The fair value of a financial instrument is the amount for which the instrument could be exchanged in a current transaction between willing parties. The level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest-level input that is significant to the fair value measurement in its entirety. The carrying amounts of cash and cash equivalents, accounts receivable, prepaid and other current assets, accounts payable, accrued expenses, deferred rent, deferred revenue, other current liabilities, and borrowings on our Revolving Credit Facility (as defined below) approximate fair value. Money market funds are categorized as Level 1. The Company’s non-financial assets, which include property and equipment, capitalized software costs, prepaid and other assets, and intangible assets, are not required to be measured at fair value on a recurring basis. However, if certain triggering events occur, or if an annual impairment test is required and the Company is required to evaluate the non-financial asset for impairment, a resulting asset impairment would require that the non-financial asset be recorded at its fair value.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash Financial instruments that potentially subject the Company to concentration of credit risk consist of cash and cash equivalents. The Company considers instruments with an original maturity of three months or less at the date of purchase to be cash equivalents. The Company’s cash and cash equivalents consist of demand deposits with financial institutions and investments in money market funds. Deposits held with these financial institutions may exceed the amount of insurance provided on such deposits. The associated risk of concentration is mitigated by banking with creditworthy institutions. The Company classifies all cash whose use is limited by contractual provisions as restricted cash. In the first quarter of 2021, letters of credit totaling $15.5 million were issued under the $50.0 million revolving credit facility (the “Revolving Credit Facility”) which reduced the remaining borrowing capacity by the same amount. These letters of credit were used in favor of our landlords, relieving us of the requirement to maintain $15.5 million of cash as collateral. As a result, the $15.5 million of restricted cash as of December 31, 2020 is no longer restricted. The following table summarizes cash and cash equivalent and restricted cash in the consolidated balance sheets (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ 2021 2020 Cash and cash equivalents ​ $ 79,733 ​ $ 90,626 Restricted cash ​ — ​ 15,500 Total ​ $ 79,733 ​ $ 106,126
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts The Company’s accounts receivable are customer obligations due under normal trade terms, carried at their face value less an allowance for doubtful accounts if required. The Company determines its allowance for doubtful accounts based on the evaluation of the aging of its accounts receivable and on a customer-by-customer analysis of its high-risk customers. The Company’s reserve contemplates its historical loss rate on receivables, specific customer situations and the economic environments in which the Company operates. The change in the Company’s allowance for doubtful accounts was as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ 2021 2020 2019 Balance as of January 1, ​ $ 1,387 ​ $ 1,122 ​ $ 1,055 Additions ​ 703 ​ 1,208 ​ 449 Write-offs, net of recoveries ​ (996) ​ (943) ​ (382) Balance as of December 31, ​ $ 1,094 ​ $ 1,387 ​ $ 1,122 ​ As of December 31, 2021, the Company had one customer that represents 11% of net accounts receivable. As of December 31, 2020, the Company had four customers that represent 13%, 13%, 12% and 10% of net accounts receivable. The Company had two customers representing 13% and 12% of total revenue for the year ended December 31, 2021, two customers representing 13% and 10% of total revenue for the year ended December 31, 2020, and two customers representing 12% and 10% of total revenue for the year ended December 31, 2019.
Film Costs	Film Costs Costs incurred to produce films (which include direct production costs, production overhead, acquisition costs and development costs) are capitalized when incurred. Capitalized film costs are amortized based upon the ratio of current period revenues to estimated total gross revenues to be earned from the film. Film costs, which were included in prepaid and other assets on the consolidated balance sheets, were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 2020 Individual Monetization: ​ ​ ​ ​ ​ ​ Feature films in production ​ $ 3,690 ​ $ 2,086 Total ​ $ 3,690 ​ $ 2,086 ​ During the year ended December 31, 2021, the Company amortized film costs of $7.1 million associated with individually monetized feature films. No amortization of film costs was recorded during the years ended December 31, 2020 or 2019. Film cost amortization is included in cost of revenue in the consolidated statements of operations. Film costs are stated at the lower of amortized cost or estimated fair value and are reviewed on a title-by-title basis when an event or change in circumstances indicates that the fair value of a film is less than its unamortized cost. During the years ended December 31, 2021, 2020 or 2019, the Company recorded no impairment charges related to film costs.
Property and Equipment	Property and Equipment Property and equipment is stated at cost, less accumulated depreciation. Depreciation on property and equipment is calculated using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life. The estimated useful lives of property and equipment of each asset category are as follows: ​ ​ ​ ​ ​ Useful Life (Years) Furniture and fixtures 5 Leasehold improvements 7 – 11 Computer equipment 3 Video equipment 3 ​
Capitalized Software Costs	Capitalized Software Costs The Company capitalizes certain costs incurred for development of websites or software for internal use. The Company capitalizes development costs when preliminary development efforts are successfully completed, management has authorized and committed project funding and it is probable that the project will be completed and the software will be used as intended. Costs include payroll and payroll-related costs of employees directly associated with the development activities. Costs incurred for enhancements that are expected to result in additional features or functionality are capitalized and amortized over the estimated useful life of the enhancements, generally 1
Investments	Investments For equity investments in entities that the Company does not exercise significant influence over, if the fair value of the investment is not readily determinable, the investment is accounted for at cost, and adjusted for subsequent observable price changes. If the fair value of the investment is readily determinable, the investment is accounted for at fair value. The Company reviews equity investments without readily determinable fair values at each period end to determine whether they have been impaired. As of December 31, 2021 and 2020, the Company had an investment in equity securities of a privately-held company without a readily determinable fair value. The total carrying value of the investment, included in prepaid and other assets on the consolidated balance sheets, was $2.3 million as of December 31, 2021 and 2020. The Company concluded that the fair value of the investment increased $0.5 million during the year ended December 31, 2020 as the result of observable price changes in orderly transactions for a similar investment in the same issuer.
Evaluation of Long-Lived Assets and Impairment	Evaluation of Long-Lived Assets and Impairment The Company reviews its property and equipment and capitalized software costs for impairment when events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. If circumstances require a long-lived asset to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by the asset to its carrying value. If the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques which may include discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. There was no impairment of long-lived assets for the years ended December 31, 2021, 2020, or 2019.
Revenue Recognition	Revenue Recognition The Company recognizes revenue in a manner that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company primarily generates its revenue from advertising services and content, which includes strategic partnerships and promotional content, with the remaining balance from other arrangements, including commerce. Advertising The Company generates its advertising revenue from managing a customer’s internet advertising campaigns to target markets both via BuzzFeed’s proprietary sites as well as premium publishers (e.g., Facebook and Google). Our performance obligations typically consist of a promised number of ads delivered or a promised number of actions related to the ads (such as impressions or views). Advertising revenue is recognized in the period that the related views, impressions, or actions by users on advertisements are delivered. When ads are placed on the Company’s owned and operated or third parties’ properties, the Company generally recognizes revenue on a gross basis because the Company is primarily responsible for the delivery of the promised services, has pricing discretion, and controls the advertising inventory prior to transfer to the customer. In some cases, the Company utilizes third party intermediaries to facilitate the sale of advertising to the end customer. In these situations, while the Company is primarily responsible for the delivery of the promised services and controls the advertising inventory prior to transfer to the end customer, the Company typically does not have insight, and does not expect to have insight, into the gross amount paid by the end customer and therefore records as revenue the net amount received from the intermediary. Content The Company generates revenue from creating content, including promotional content, customer advertising, and feature films. The Company’s performance obligations consist of Company-created content for use by its customers or the delivery of a promised number of actions related to the content (impressions or views). The revenue is recognized when the content, or the related action, is delivered. Commerce The Company participates in multiple marketplace arrangements with third parties such as Amazon whereby the Company provides affiliate links which redirect the audience to purchase products and/or services from the third parties. When the participant purchases a product and/or service, the Company receives a commission fee for that sale from the third parties. The revenue is recognized when a successful sale is made and the commission is earned.
Cost of Revenue	Cost of Revenue Cost of revenue consists primarily of compensation-related expenses and costs incurred for the publishing of editorial, promotional, and news content across all platforms, as well as amounts due to third party websites and platforms to fulfil customers’ advertising campaigns. Web hosting and advertising serving platform costs are also included in cost of revenue.
Sales and Marketing	Sales and Marketing Sales and marketing expenses consist primarily of compensation-related expenses for sales employees. In addition, marketing and sales-related expenses include advertising costs, market research, and branding.
General and Administrative	General and Administrative General and administrative expense consists primarily of compensation-related expenses for corporate employees. Also, it consists of expense for facilities, professional services fees, insurance costs, and other general overhead costs.
Research and Development	Research and Development Research and development (“R&D”) expenses consist primarily of compensation-related expenses incurred for the development of, enhancements to, and maintenance of the Company’s website, technology platforms and infrastructure. R&D expenses that do not meet the criteria for capitalization are expensed as incurred. Certain development expenses are capitalized under the provisions of the applicable authoritative guidance, whereby the Company capitalizes costs associated with website and internal-use software systems that have reached the application development stage.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded for deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company recognizes tax benefits from uncertain tax positions if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The Company made a policy election to treat the income tax with respect to GILTI as a period expense when incurred.
Stock-Based Compensation	Stock-Based Compensation Stock-based compensation is recognized as an expense in the consolidated financial statements and is measured at the fair value of the award. The Company recognizes compensation expense for stock awards based on grant date fair value using the Black-Scholes option-pricing model. The Company accounts for forfeitures as they occur. The Company adopted Accounting Standards Update (“ASU”) 2018-07, Improvements to Non-employee Share-Based Payment Accounting The following table summarizes stock-based compensation cost included in the consolidated statements of operations: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ 2021 2020 2019 Cost of revenue, excluding depreciation and amortization ​ $ 2,788 ​ $ 109 ​ $ 353 Sales and marketing ​ 4,829 ​ 60 ​ 658 General and administrative ​ 15,052 ​ 977 ​ 1,446 Research and development ​ 896 ​ 43 ​ 356 ​ ​ $ 23,565 ​ $ 1,189 ​ $ 2,813 ​ The Company recognized no income tax benefit in the consolidated statements of operations for stock-based compensation arrangements in 2021, 2020 or 2019.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) includes certain changes in stockholders’ equity that are excluded from net income (loss) such as cumulative foreign currency translation adjustments, unrealized gains or losses on marketable securities, and comprehensive income (loss) attributed to the redeemable noncontrolling interest.
Foreign Currency	Foreign Currency The functional currency of our foreign subsidiaries are generally the local currency. The financial statements of these subsidiaries are translated into U.S. dollars using month-end rates of exchange for assets and liabilities, and average rates of exchange for revenue, costs and expenses. Translation gains and losses are recorded in accumulated other comprehensive loss in stockholders’ equity. Transaction gains and losses including intercompany transactions denominated in a currency other than the functional currency of the entity involved are included in foreign exchange gain (loss) within other income, net in the consolidated statements of operations. The Company does not enter into foreign currency forward exchange contracts or other derivative financial instruments to hedge the effects of adverse fluctuations in foreign currency exchange rates.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements The Company, an emerging growth company, or EGC, has elected to take advantage of the benefits of the extended transition period provided for in Section 7(a)(2)(B) of the Securities Act, for complying with new or revised accounting standards which allows the Company to defer adoption of certain accounting standards until those standards would otherwise apply to private companies. In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40), Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity retrospective transition method. The Company elected to early adopt ASU 2020-06 effective January 1, 2021. The adoption of ASU 2020-06 did not have a significant impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other (Topic 350): Internal-Use Software On January 1, 2020, the Company adopted ASU 2018-13, Fair Value Measurement (Topic 820) — Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement On January 1, 2021, the Company adopted the amended guidance in ASU 2019-02, Improvements to Accounting for Costs of Films and License Agreements for Program Materials On January 1, 2019, the Company adopted Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606)
