These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K Restricted Cash Restricted cash represents amounts required to be held as collateral in a money market account for treasury management service agreements. The Company held $0.1 million of restricted cash as of March 31, 2022 and December 31, 2021. The following table presents the Company’s cash, cash equivalents and restricted cash by category in the Company’s Condensed Consolidated Balance Sheets (in thousands): March 31, 2022 December 31, Cash and cash equivalents $ 188,070 $ 126,526 Restricted cash 104 103 Cash, cash equivalents, and restricted cash $ 188,174 $ 126,629 Revenue Recognition The Company derives revenue from two primary sources: Event Cloud subscription-based solutions and Hospitality Cloud marketing and subscription-based solutions. Subscription services revenue consists primarily of fees to provide the Company’s customers with access to its cloud-based platform. Subscription service contracts do not provide customers with the right to take possession of the software, are non-cancellable, Certain contracts may include multiple distinct performance obligations which may consist of some or all of subscription services, marketing packages, and professional services. When an arrangement includes multiple performance obligations relating to SaaS subscriptions, which are concurrently delivered and have the same pattern of transfer to the customer (the services transfer to the customer ratably over the contract period), the entire contract value is recognized on a straight-line basis over the contract term. When an arrangement includes multiple performance obligations that do not have the same pattern of transfer to the customer, revenue is recognized at each performance obligation’s respective standalone selling price (“SSP”), when the performance obligations are satisfied. The SSP is the price at which the Company would sell a promised good or service separately to a customer. The Company estimates SSP based on internal margin analysis, competitor data, and other industry standards for SaaS-based companies. Segment and Geographic Data Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has determined that it operates in one operating segment and one reportable segment, as the CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. Property and equipment outside North America geographic locations represented 32.2% and 33.4% of total property and equipment, net as of March 31, 2022 and December 31, 2021, respectively, and are located primarily in India. The composition of the Company’s property and equipment between North America and locations outside of North America is set forth below (in thousands):​​​​​​​ March 31, 2022 December 31, North America $ 9,986 $ 10,205 Outside North America 4,741 5,129 Total $ 14,727 $ 15,334 Net Loss per Share of Common Stock Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share adjusts basic earnings per share for the potentially dilutive impact of stock options. As the Company has reported losses for all periods presented, all potentially dilutive securities, including stock options, are antidilutive and accordingly, basic net loss per share equals diluted net loss per share. For the three months ended March 31, 2022 and 2021, 55,354,536 and 36,768,058 stock options were excluded from the computation of diluted net loss per share of common stock, respectively, because including them would have been antidilutive.

Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”). The Reverse Recapitalization Transaction between Dragoneer and Legacy Cvent was accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Dragoneer was treated as the acquired company and Legacy Cvent was treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the Reverse Recapitalization Transaction was treated as the equivalent of Legacy Cvent issuing stock for the net assets of Dragoneer, accompanied by a recapitalization. The net assets of Dragoneer are stated at historical cost, with no goodwill or other intangible assets recorded. Legacy Cvent was determined to be the accounting acquirer based on the following predominant factors: • Legacy Cvent’s existing stockholders had a majority of the voting power in the Company following the Reverse Recapitalization Transaction; • Legacy Cvent had the ability to nominate a majority of the initial members of our Board; • Legacy Cvent’s senior management is the senior management of the Company; • Legacy Cvent’s operations prior to the Reverse Recapitalization Transaction comprised the ongoing operations of the Company; • Legacy Cvent is the larger entity based on historical operating activity and had the larger employee base prior to the Reverse Recapitalization Transaction; and • The post-combination company assumed a Legacy Cvent branded name: “Cvent Holding Corp.” The consolidated assets, liabilities and results of operations prior to the Reverse Recapitalization Transaction are those of Legacy Cvent. The shares and corresponding capital amounts and losses per share, prior to the Reverse Recapitalization Transaction, have been retroactively restated based on shares reflecting the exchange ratio established in the Reverse Recapitalization Transaction of approximately 454:1, with the exception of the authorized shares and shares reserved for issuance. See Note 3. Reverse Recapitalization Transaction for more information. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions made by management include estimated useful lives of property and equipment, capitalized software development costs, capitalized sales commissions, the valuation of goodwill and intangibles, allowances for doubtful accounts, valuation of deferred tax assets, certain assumptions related to stock-based compensation, including the estimated value of the Company’s common stock and, income taxes. As of the date the financial statements were available for issuance, we are not aware of any specific events or circumstances that would require us to update our estimates, judgments, or to revise the carrying values of our assets or liabilities. Actual results could differ from those estimates and assumptions. Cash and Cash Equivalents Highly liquid financial instruments purchased with original maturities of or less at the date of purchase are reported as cash equivalents. Cash equivalents are recorded at cost, which approximates fair value due to their short-term maturities. Included in cash and cash equivalents are funds representing amounts reserved for registration fees processed on behalf of customers. While these cash accounts are not restricted as to their use, a liability for amounts due to customers under these arrangements has been recorded in Fees payable to customers in the accompanying consolidated balance sheets. Fees payable to customers were $25.0 million and $16.9 million as of December 31, 2021 and 2020, respectively. Restricted Cash Restricted cash represents amounts required to be held as collateral in a money market account for treasury management service agreements. The Company held $0.1 million and $0.2 million of restricted cash as of December 31, 2021 and 2020, respectively. The following table presents the Company’s cash, cash equivalents and restricted cash by category in the Company’s Consolidated Balance Sheets (in thousands): As of December 31, 2021 2020 Cash and cash equivalents $ 126,526 $ 65,265 Restricted cash 103 205 Cash, cash equivalents, and restricted cash $ 126,629 $ 65,470 Short-term Investments All highly liquid investments with stated maturity dates between three months and one year from the purchase date are classified as short-term investments. The Company determines the appropriate classification of its short-term investments at the time of purchase. The Company’s short-term investments consist of highly liquid financial instruments, which are comprised of certificates-of-deposit, Accounts Receivable Accounts receivable includes billed and unbilled receivables, net of allowance for credit losses. Accounts receivable are recorded at the amount invoiced to customers and do not bear interest. The Company estimates the allowance for expected credit loss based on collectability of accounts receivable and unbilled receivables by considering various factors, including the age of the accounts receivable balances, historical write-off Year Ended December 31, 2021 2020 2019 Allowance for expected credit losses, beginning of period $ 3,287 $ 1,912 $ 3,379 Credit loss expense 8,316 3,280 1,407 Write-offs and adjustments (7,056 ) (1,905 ) (2,874 ) Allowance for expected credit losses, end of period $ 4,547 $ 3,287 $ 1,912 Credit loss expense during the years ended December 31, 2021, 2020, and 2019 was $8.3 million, $3.3 million, and $1.4 million, respectively. As a result of the volatility in global markets and economies and the financial difficulties faced by many of its customers, the Company has increased the allowance for expected credit losses. The Company does not have any off-balance Revenue Recognition The Company derives revenue from two primary sources: Event Cloud subscription-based solutions and Hospitality Cloud marketing and subscription-based solutions. Subscription services revenue consists primarily of fees to provide the Company’s customers with access to its cloud-based platform. Subscription service contracts do not provide customers with the right to take possession of the software, are non-cancellable, Certain contracts may include multiple distinct performance obligations which may consist of some or all of subscription services, marketing packages, and professional services. When an arrangement includes multiple performance obligations relating to SaaS subscriptions, which are Revenue from services transferred to the customer on currently delivered and have the same pattern of transfer to the customer (the services transfer to the customer ratably over the contract period), the entire contract value is recognized on a straight-line basis over the contract term. When an arrangement includes multiple performance obligations that do not have the same pattern of transfer to the customer, revenue is recognized at each performance obligation’s respective standalone selling price (“SSP”), when the performance obligations are satisfied. The SSP is the price at which the Company would sell a promised good or service separately to a customer. The Company estimates SSP based on internal margin analysis, competitor data, and other industry standards for SaaS-based companies. Event Cloud Revenue Event Management The Company generates the majority of its Event Cloud revenue through four primary sources: 1) Software-as-a-Service in-person, Event and Conference Management Platform SaaS subscriptions to the event and conference management platforms may include functionality that enables customers to manage the registration of people that plan to attend the customer’s event or events. At any time during the subscription term, customers may elect to purchase blocks of additional registrations (“reg blocks”) and other features or functionality (“non-reg”), transaction price of the original contract. Accordingly, a cumulative revenue catch-up Non-reg non-reg Attendee Hub and Mobile Apps Subscription-based solutions also include the sale of mobile event apps for in-person, Onsite Event Solutions Event specific onsite solutions include the rental of equipment and consultants needed to successfully manage and execute a complex event, along with the SaaS to manage appointments, exhibitors, speakers, and lead capture and to aggregate all of this information to understand attendee interests. Revenue related to rental of equipment and consultants is recognized based on the contractual stated value, which approximates its relative standalone selling price, and is generally recognized at a point in time as the services are performed and the performance obligations are satisfied. Revenue related to the Company’s SaaS subscriptions to its onsite solutions are considered a service arrangement and recognized to revenue over time, on a straight-line basis over the term of the subscription arrangement. Hospitality Cloud Revenue The Hospitality Cloud offers cloud-based SaaS solutions to drive increased demand across the hotel group sales lifecycle from advertising to lead management tools. Group Marketing Solutions Group marketing solutions revenue is generated through the delivery of various forms of advertising sold through annual or multi-year contracts to hotels and venues. Advertising is sold as a stand ready obligation to deliver advertising, and accordingly revenue is recognized over time on a straight-line basis as the performance obligation is satisfied and the advertisement is displayed. Such solutions include prominent display of a customer’s venue within the Cvent Supplier Network to find and book physical event space. Pricing for the advertisements is based on the term of the advertisement, targeted geography, market tier, number of advertisements and prominence of the ad placement. Cloud-Based SaaS Solutions The Hospitality Cloud also offers a variety of cloud-based SaaS solutions such as 1) Passkey, which allows hotels, convention and visitor bureaus and meeting management companies to streamline and automate hotel room blocks; hotels also use Passkey to create upsell opportunities with group guests, who in turn gain a simpler way to make and manage their hotel reservations. 2) Business Transient, which simplifies how hotels attract, manage and win corporate travel business, publish data to Global Distribution Systems and online travel agency websites, and 3) Event Diagramming, a collaborative SaaS tool that empowers event planners and venues to work together to design the optimal venue layout before an event occurs. This technology enables meeting spaces to be viewed in a three-dimensional rendering which facilitates designing the optimal room layout to scale that includes tables, chairs, stages, and other structures used for events. Revenue for Passkey, Business Transient and Event Diagramming is generated through the delivery of SaaS subscriptions to the respective cloud-based platform. The entire subscription fee is recognized over time on a straight-line basis over the term of the subscription arrangement as the performance obligation is satisfied. Business Combinations The Company allocates the purchase price of acquired companies to the identifiable tangible and intangible assets acquired and liabilities assumed at the acquisition date based upon their estimated fair values. This allocation and valuation requires management to make significant estimates and assumptions, specifically with respect to long-lived and intangible assets. Critical estimates in valuing intangible assets include, but are not limited to, estimates regarding: future expected cash flows from customer contracts, customer lists, discount rates, distribution agreements, developed proprietary technology including acquired software platforms and non-competition In addition, uncertain tax positions and tax-related Transaction costs related to acquisitions are expensed as incurred. Leases The Company determines whether an arrangement is or contains a lease at contract inception, and arrangements meeting the definition of a lease are classified as operating or financing leases at the lease commencement date. For leases with an original term longer than twelve months, lease liabilities are initially recognized on the lease commencement date based on the present value of the future minimum lease payments over the lease term. A corresponding right-of-use non-lease non-lease non-cancellable Deferred Revenue Deferred revenue consists of contractual billings made for which the contract start date has passed or where payments have been received in advance of revenue recognition from Event Cloud solutions or Hospitality Cloud solutions. The Company generally invoices customers in annual or quarterly installments. Customer invoices are generally due 30 days from the time of invoicing. The Company does not have significant financing components in its contracts as the Company expects to receive full payment for its services within one year from the date of transfer of services to customers. Cost of Revenue Cost of revenue primarily consists of employee-related expenses, including salaries, benefits, bonuses and stock-based compensation, related to providing support and hosting our applications, costs of cloud-based data center capacity, software license fees, costs to support our onsite solutions and virtual products, interchange fees related to merchant services and amortization expense associated with capitalized software. In addition, we allocate a portion of overhead, such as rent and depreciation and amortization to cost of revenue based on headcount. Property and Equipment Property and equipment is stated at cost less accumulated depreciation and amortization. Improvements and replacements of property and equipment are capitalized. Maintenance and repairs that do not improve or extend the lives of property and equipment are charged to expense as incurred. When assets are sold or retired, their cost and related accumulated depreciation are removed from the ledger and any gain or loss is reported in operating loss in the accompanying consolidated statements of operations and comprehensive loss. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. The estimated useful life of computer equipment and purchased software is three years while the estimated useful lives of furniture and equipment is seven years. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or estimated useful life of the asset. Capitalized Software Development Costs Costs incurred during the application development stage to develop software directly used in the delivery of revenue generating activities are capitalized and recorded as capitalized software development costs on the consolidated balance sheet in accordance with the provisions of FASB ASC Subtopic 350-40, Intangibles – Goodwill and Other Subtopic 40 Internal-Use on a project-by-project basis in the application development stage. project-by- Impairment of Long-Lived Assets Long-lived assets are reviewed for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. If such review indicates that the carrying amount of long- lived assets is not recoverable from future undiscounted cash flows, the carrying amount of such assets is reduced to the lower of the carrying value or fair value. In addition to the recoverability assessment, the Company routinely reviews the remaining estimated lives of its long-lived assets. Any reduction in the useful life assumption will result in increased depreciation and amortization expense in the period when such determinations are made, as well as in subsequent periods. There was no change to the useful lives of long-lived assets for the years-ended December 31, 2021 and 2020. Goodwill Goodwill represents the excess of: (i) the aggregate of the fair value of consideration transferred in a business combination, over (ii) the fair value of assets acquired, net of liabilities assumed. Goodwill is not amortized but is subject to annual impairment tests. The Company adopted Accounting Standards Update No 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment The Company performs an annual impairment review of goodwill, or when a triggering event occurs between annual impairment tests. The Company operates as one reporting unit. The Company’s test for goodwill impairment starts with a qualitative assessment to determine whether it is necessary to perform a quantitative goodwill impairment test. If qualitative factors indicate that the fair value of the reporting unit is more likely than not less than its carrying amount, then a quantitative goodwill impairment test is performed. Under the quantitative impairment test, if the carrying amount of the reporting unit exceeds its fair value, then an impairment loss is recognized in an amount equal to that excess, not to exceed the total amount of goodwill. During the 2021 qualitative assessment of goodwill, management concluded that it was more likely than not that the fair value of the Company’s reporting unit exceeded its carrying value, resulting in no indication of impairment as of December 31, 2021. Research and Development Research and development expenses consist primarily of personnel and related expenses for our research and development staff, including salaries, benefits, bonuses and stock-based compensation and the cost of third-party contractors. Research and development expenses, other than software development costs that qualify for capitalization, are expensed as incurred. In addition, we allocate a portion of overhead, such as rent and depreciation to research and development based on headcount. Sales Commissions Commissions earned by the Company’s sales personnel are considered incremental costs of obtaining a contract with a customer. Accordingly, sales commissions are capitalized when incurred and amortized on a straight-line basis over the Company’s average historical customer life, which is determined based on the underlying product line and ranges from one four by reviewing the average length of its customers contracts, changes in technology, expected contract renewals and customer retention, and other industry factors. The Company re-assesses The current portion of capitalized commissions, net was $25.4 million and $22.0 million as of December 31, 2021 and 2020, respectively. The noncurrent portion of capitalized commissions, net was $23.0 million and $20.4 million as of December 31, 2021 and 2020, respectively. During the years ended December 31, 2021, 2020, and 2019, $29.3 million, $29.1 million, and $25.6 million, respectively, of capitalized commissions were amortized to sales and marketing expense in the accompanying consolidated statements of operations and comprehensive loss. 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 the existing assets and liabilities, and their respective income 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. The Company establishes a valuation allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. The Company only recognizes the tax benefit from an uncertain tax position if it is more likely than not that the tax position will be sustained on examination. The Company is subject to tax on global intangible low-taxed Stock-Based Compensation Employee stock-based compensation is recognized as a cost in the consolidated statements of operations and comprehensive loss. For both equity-classified and liability-classified awards, such cost is measured at the grant date fair value of the award. We estimate the grant date fair value for stock options using the Black-Scholes option-pricing model. The Black-Scholes pricing model requires the use of subjective assumptions including the expected term of the options, the price volatility of the underlying stock, dividend yield, and a discount for the lack of marketability. The expected dividend yield is zero, as we have not previously declared cash dividends and do not currently intend to declare cash dividends in the foreseeable future. Prior to the Company becoming publicly traded, because we were privately-held, the Black-Scholes pricing inputs, including the grant date fair value of the underlying common stock, volatility of the underlying stock, and a discount for the lack of marketability, were estimated based on our peer group companies, which are publicly-traded. Our peer group was established through consultation with our external valuation firm; our ultimate parent entity, an affiliate of Vista Equity Partners Management, LLC (“Vista”); and confirmed through the review of the performance and valuation attributes of our peer group to determine that our public-company peer group is a reasonable and fair proxy for our share performance, if our shares were publicly-traded. The risk-free rate for the expected term of the option was based on the U.S. Treasury yield curve at the date of grant. The initial determination of compensation cost is based on the number of stock options or other awards granted, which is then amortized over the vesting period. Liability classified awards are remeasured to fair value at each reporting date with the corresponding change in value recorded in the consolidated statements of operations and comprehensive loss. The Company recognizes expense over the requisite service period on a straight-line basis. The Company records the impact of forfeitures on stock compensation expense in the period the forfeitures occur. Comprehensive Loss Comprehensive loss comprises net loss and foreign currency translation gains/(losses) for the years ended December 31, 2021, 2020, and 2019, respectively. Foreign Currency The Company’s foreign subsidiary in India designates the U.S. dollar as its functional currency. For this subsidiary, assets and liabilities denominated in currencies other than the U.S. dollar are remeasured into U.S. dollars at current exchange rates for monetary assets and liabilities and historical exchange rates for non-monetary The functional currency for certain of the Company’s other foreign subsidiaries is the local currency. For those subsidiaries, the assets and liabilities are translated into U.S. dollars at exchange rates in effect as of the balance sheet date. Revenue and expense items are translated based on average exchange rates for the period. Foreign currency (gains)/losses associated with realized transactions and remeasurement, recorded in other income/(expense), net, were $(0.8) million, $0.8 million, and $1.5 million for the years ended December 31, 2021, 2020, and 2019 respectively. Non-Monetary The Company occasionally participates in non-monetary Non-monetary Non-monetary Non-monetary Fair Value Measurements Fair value represents the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on the following three levels of inputs, of which the first two are considered observable and the last one is considered unobservable: Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 Inputs: Unobservable inputs that require the Company to use present value and other valuation techniques in the determination of fair value. The Company’s financial instruments include cash and cash equivalents, restricted cash, short-term investments, accounts receivable, accounts payable and accrued liabilities. The carrying value of these financial instruments on the consolidated balance sheets approximate their fair value based on their short-term maturities. Debt Issuance Costs Costs incurred with lenders and other third parties that are specific and incremental costs required to obtain debt are amortized as interest expense over the life of the debt using the effective interest method. Unamortized debt issuance costs are presented as a direct reduction of the carrying value of the related debt. Segment and Geographic Data Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has determined that it operates in one operating segment and one reportable segment, as the CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. Property and equipment outside America geographic locations represented 33.4% and 21.8% of total property and equipment, net as of December 31, 2021 and 2020, respectively, and are located primarily in India. The composition of the Company’s property and equipment between North America and locations outside of North America is set forth below (in thousands): Year Ended 2021 2020 North America $ 10,205 $ 16,976 Outside North America 5,129 4,739 Total $ 15,334 $ 21,715 Net Loss per Share of Common Stock Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share adjusts basic earnings per share for the potentially dilutive impact of stock options. As the Company has reported losses for all periods presented, all potentially dilutive securities including stock options, are antidilutive and accordingly, basic net loss per share equals diluted net loss per share.

Revenue Disaggregation of Revenue The Company derives revenue from two primary sources: Event Cloud subscription-based solutions and Hospitality Cloud marketing and subscription-based solutions. They are principally generated from North America, which comprises the United States and Canada, with Canada representing 2.4% of total revenue for each of the three months ended March 31, 2022 and 2021. Revenue from sources outside North America represented 12.0% and 13.6% of total revenue for three months ended March 31, 2022 and 2021, respectively. The Company’s disaggregation of revenue primary geographic region is as follows (in thousands):​​​​​​​ Three Months Ended March 31, 2022 2021 North America $ 120,823 $ 101,282 Outside North America 16,533 16,005 Revenue $ 137,356 $ 117,287 The Company’s disaggregation of revenue by major business activity is as follows (in thousands): Three Months Ended March 31, 2022 2021 Event Cloud $ 94,988 $ 81,133 Hospitality Cloud 42,368 36,154 Revenue $ 137,356 $ 117,287 Deferred Revenue Deferred revenue represents billings under signed contracts before the related products or services are transferred to customers. The portion of deferred revenue that is expected to be recognized as revenue during the subsequent 12-month non-current, Remaining Performance Obligations For multiple-year agreements for either Event Cloud or Hospitality Cloud, we typically invoice the amount for the first year of the contract at signing followed by subsequent annual invoices at the anniversary of each year. Since we bill most of our customers in advance, there can be amounts that we have not yet been contractually able to invoice. Until such time as these amounts are invoiced or recognized in revenue, they are considered by us to be unbilled contract value, and together with deferred revenue, remaining performance obligations. As of March 31, 2022 and December 31, 2021, our total current deferred revenue was $287.5 million and $239.8 million, respectively, which amount does not include unbilled contract value for contracts of approximately $518.8 million and $573.4 million, respectively. We expect that the amount of unbilled contract value relative to the total value of our contracts will change from year to year for several reasons, including the amount of cash collected early in the contract term, the specific timing and duration of customer agreements, varying invoicing cycles of agreements, the specific timing of customer renewal, changes in customer financial circumstances and foreign currency fluctuations. We expect to recognize 69.2% of our remaining performance obligations as revenue over the subsequent 24 months, and the remainder thereafter.

The ultimate realization is dependent on the generation of taxable income within the periods that those temporary differences become deductible. Management believes certain net operating loss carry forwards and other credit carry forwards may not be realizable before they expire. Accordingly, the Company has recorded a valuation allowance on such deferred tax assets in the amount of $108.1 million and $81.5 million as of December 31, 2021 and 2020, respectively. The change in the Company’s valuation allowance is as follows (in thousands): As of December 31, 2021 2020 2019 Valuation allowance, beginning of year $ 81,461 $ 72,783 $ 44,752 Increase 26,661 8,678 28,031 Valuation allowance, end of year $ 108,122 $ 81,461 $ 72,783 The Company had approximately $454.3 million and $449.4 million of federal net operating loss carryforwards for federal income tax return purposes as of December 31, 2021 and 2020, respectively. The tax effected amounts of these carryforwards are $95.4 million and $94.4 million as of December 31, 2021 and 2020, respectively. The tax effected state net operating carryforwards are $22.9 million and $26.6 million as of December 31, 2021 and 2020, respectively. Additionally, the tax effected foreign net operating loss carryforwards are $2.2 million and $2.7 million as of December 31, 2021 and 2020, respectively. $142.9 million of the federal net operating loss carryforward was generated after December 31, 2017 and does not expire; the remaining portion of these net operating loss carryforwards will expire, if unused, in varying amounts beginning in . The Company’s state and foreign net operating losses will expire between and if unused. The realization of the benefits of the net operating loss carryforwards is dependent on sufficient taxable income in future years. Among other things, the lack of future earnings, or a change in ownership of the Company, could adversely affect the Company’s timing and ability to utilize the net operating loss carryforward to reduce future current tax expense. The Company believes that it is more likely than not that the benefit from certain federal and state net operating loss carryforwards will not be realized. In recognition of this assessment, the Company provided a valuation allowance of $96.0 million as of December 31, 2021 on the deferred tax assets relating to the federal and state net operating loss carryforwards. The total valuation allowance relating to these net operating loss carryforwards and other deferred tax assets was $108.1 million as of December 31, 2021. The Company records tax liabilities for uncertainties relate to federal, state, and international tax positions. The estimated values of the Company’s gross uncertain tax positions are as follows (in thousands): As of December 31, 2021 2020 2019 Unrecognized tax benefits, beginning of year $ 865 $ 853 $ 833 Reductions for tax positions for prior years 116 56 100 Lapse of statute of limitations (39 ) (44 ) (80 ) Unrecognized tax benefits, end of year $ 942 $ 865 $ 853 The Company does not believe it is reasonably possible that the composition of its unrecognized tax benefits would materially change in the next 12 months. The Company’s practice is to recognize interest and penalties related to uncertain tax positions in income tax expense. The amount of interest and penalties included in income tax expense was $0.1 million, $0.1 million, and $0.1 million for the years ended December 31, 2021, 2020, and 2019 respectively. The Company had approximately $1.2 million and $1.1 million for the payment of interest and penalties accrued for the years ended December 31, 2021 and 2020, respectively. The Company operates under a tax holiday in India, which is effective through March 31, 2029. The tax holidays are conditional upon our meeting certain employment and investment thresholds. The impact of these tax holidays decreased foreign taxes by $2.0 million, $0.2 million, $1.3 million for the years ended December 31, 2021, 2020, and 2019 respectively. The Company is subject to U.S. federal income tax, foreign income tax, and state and local income tax in multiple jurisdictions. With few exceptions, the Company is no longer subject to income tax examinations by the U.S. federal, foreign, state, or local tax authorities for years before 2011. While the federal statute of limitations generally is three years, the IRS can re-determine operating

The weighted-average grant date fair value of options granted during the three months ended March 31, 2022 was $3.72 per share. The total intrinsic value of options that were exercised during the three months ended March 31, 2022 was $0.5 million. During the three months ended March 31, 2022, 140,970 options were exercised. As of March 31, 2022, the $47.6 million in unrecognized compensation cost related to stock options will be recognized over a weighted-average period of 1.64 years. Restricted Stock Units During the three months ended March 31, 2022, the Company granted 12,043,248 service-based restricted stock units (“RSUs”), 3,731 of which had vested as of March 31, 2022. The outstanding RSUs vest on dates ranging from March 2022 to March 2026 as measured from the grant date. Stock-based Compensation Expense Stock-based compensation expense for equity and liability classified awards is recognized using the straight-line attribution method. In addition, the Company ensures that it has fully recognized expense for at least the option and RSU tranches that have fully vested in the period in which they vest. Stock-based compensation expense is summarized as follows (in thousands): Three Months Ended March 31, 2022 2021 Cost of revenue $ 590 $ 59 Sales and marketing 2,980 335 Research and development 2,588 141 General and administrative 3,610 73 Total stock-based compensation $ 9,768 $ 608 2021 Employee Stock Purchase Plan At the Special Meeting of the shareholders of Dragoneer on December 7, 2021, the shareholders of Dragoneer considered and approved the Cvent Holding Corp. 2021 Employee Stock Purchase Plan (the “ESPP”), which was adopted by the Board and became effective for the Company immediately upon the closing of the Reverse Recapitalization Transaction. The ESPP permits employees to purchase common stock through payroll deductions during biannual offering periods, or during such other offering periods as the Board of Directors may determine. Participants may authorize payroll deductions of a specific percentage of compensation not to exceed 15%, with such deductions being accumulated for biannual purchase periods beginning on the first business day of each offering period and ending on the last business day of each offering period. Under the terms of the ESPP, the purchase price per share will equal 85% of the fair market value of a share of common stock on the first day of an offering period or the last date of an offering period, whichever is lower, although the Board of Directors has discretion to change the purchase price with respect to future offering periods. At March 31, 2022, there were 11,500,000 shares available for issuance under the ESPP. No contributions were made by employees during the three months ended March 31, 2022. The first ESPP offering period will begin on June 1, 2022. 2017 Long-Term Incentive Plan The Company recorded no expense for the 2017 Long-Term Incentive Plan (the “2017 LTI Plan”) during the three months ended March 31, 2022 and 2021 because the incentive remains unvested and the Company is only liable to make the 2017 LTI Plan cash bonus payments upon a sale of the Company, or other Qualified Event, as defined in the 2017 LTI Plan, which is not currently determined to be probable. On February 28, 2022, the Compensation and Nominating Committee of the Board approved a plan that allows employees to convert their awards (the “Legacy Cvent LTIP Awards”) granted under the 2017 LTI Plan to an aggregate of approximately 3.7 million RSUs in exchange for cancellation of such employees’ outstanding Legacy Cvent LTIP Awards. The RSUs are subject to	11. Stockholders’ Equity The Company’s Certificate 2021 Omnibus Incentive Plan At the Special Meeting of the shareholders of Dragoneer on December 7, 2021, the shareholders of Dragoneer considered and approved the Cvent Holding Corp. 2021 Omnibus Incentive Plan (the “2021 Plan”), which was adopted by the Board, effective as of December 8, 2021 (the “Effective Date”). The 2021 Plan authorizes the issuance of 110,500,000 shares of Common Stock (the “Share Reserve”). The Share Reserve may consist of authorized and unissued shares and shares held in or acquired for the treasury of the Company. The Share Reserve will automatically increase on each January 1 that occurs after the Effective Date, for 10 years, by an amount equal to 5% of the total number of shares outstanding on December 31 of the preceding calendar year, or a lesser number as may be determined by the Board of Directors. The Board of Directors has the full authority to grant, under the terms and conditions of the 2021 Plan, to Eligible Individuals (as defined in the 2021 Plan): stock options, stock appreciation rights, restricted shares, performance awards, other share-based awards, and other cash-based awards. The maximum number of shares with respect to which incentive stock options may be granted is 58,735,076 shares. With respect to Stock Appreciation Rights settled in shares, upon settlement, only the number of shares delivered to a Participant will count against the Share Reserve. If any stock option, stock appreciation right, or other share-based award expires, terminates, or is cancelled for any reason without having been exercised in full, the number of shares underlying such Award will be added back to the Share Reserve. Furthermore, no non-employee The Board of Directors may amend, alter or discontinue the 2021 Plan, but no amendment alteration or discontinuance may materially impair the rights of an equity award previously granted under the 2021 Plan without the award holder’s consent, except such amendments made to comply with applicable law. As indicated above, several types of awards are available for grant under the 2021 Plan. In connection with the closing of the Reverse Recapitalization Transaction, 51,649,748 nonqualified stock options from the 2017 Plan (as defined below) were exchanged for an equal number of nonqualified stock options under the 2021 Plan, subject to the same vesting terms as the corresponding Legacy Cvent options. Stock Options As of December 31, 2021, there were 51,646,456 non-qualified On February 28, 2022 the Compensation and Nominating Committee of the Board approved a pool of stock awards to officers and other key employees, to an aggregate of approximately 4.1 million stock options and approximately 12.6 million restricted stock units (“RSUs”). These awards were granted under the 2021 Plan and vest on dates ranging from March 2022 to March 2026 as measured from the grant date. 2021 Employee Stock Purchase Plan At the Special Meeting of the shareholders of Dragoneer on December 7, 2021, the shareholders of Dragoneer considered and approved the Cvent Holding Corp. 2021 Employee Stock Purchase Plan (the “ESPP”), which was adopted by the Board and became effective for the Company immediately upon the Closing. The ESPP permits employees to purchase common stock through payroll deductions during biannual offering periods, or during such other offering periods as the Board of Directors may determine. Participants may authorize payroll deductions of a specific percentage of compensation not to exceed 15%, with such deductions being accumulated for biannual purchase periods beginning on the first business day of each offering period and ending on the last business day of each offering period. Under the terms of the ESPP, the purchase price per share will equal 85% of the fair market value of a share of common stock on the first day of an offering period or the last date of an offering period, whichever is lower, although the Board of Directors has discretion to change the purchase price with respect to future offering periods. At December 31, 2021, there were 11,500,000 shares available for issuance under the ESPP. No contributions were made by employees during the year ended December 31, 2021. F-31 2017 Stock Option Plan On May 26, 2017, the Board of Directors of the Papay Topco, Inc. approved a stock option plan (the “2017 Plan”) to provide incentives to its employees, directors, officers, consultants and/or advisors of Papay Topco, Inc. The 2017 Stock Option Plan provides for the grant of stock options to employees and officers of the Company. Following the adoption of the 2021 Plan, the 2017 Plan was terminated and all outstanding options were rolled over using a rate of approximately 454:1. Stock-based Compensation The weighted average assumptions used in the valuation of stock option awards granted under the Black- Scholes model are summarized as follows: Year Ended December 31, 2021 2020 2019 Dividend yield — — — Volatility 45.44 % 44.65 % 37.60 % Expected term (years) 5.88 5.89 5.89 Risk-free interest rate 1.32 % 0.65 % 1.80 % Stock-based Compensation Activity Rollforward Stock options Number of Weighted Weighted Aggregate Unrecognized Balance at January 1, 2020 37,912,097 $ 3.74 Granted 294,065 3.69 Exercised (500,543 ) 5.34 Forfeited (396,626 ) 3.67 Expired (280,905 ) 4.35 Balance at December 31, 2020 37,028,088 $ 3.74 6.08 $ 49,446 $ 2,708 Granted 15,401,179 5.08 Exercised (375,747 ) 3.76 Forfeited (316,303 ) 5.06 Expired (90,761 ) 3.87 Balance at December 31, 2021 51,646,456 $ 4.13 6.29 $ 208,614 $ 40,337 Vested and exercisable as of December 31, 2020 35,314,526 $ 3.68 6.43 $ 49,262 $ — Vested and exercisable as of December 31, 2021 43,842,127 $ 3.71 5.47 $ 195,710 $ — The weighted-average grant date fair value of options granted during the years ended December 31, 2021, 2020, and 2019 (after accounting for the 454:1 Reverse Recapitalization Transaction exchange ratio described above) was $4.10, $2.11 and $2.07 per share, respectively. The total intrinsic value of options that were exercised during the years ended December 31, 2021, 2020, and 2019 was $1.7 million, $0.7 million, and $16.2 million, respectively. As of December 31, 2021, the $40.3 million in unrecognized compensation cost related to stock options will be recognized over a weighted average period of 1.19 years. F-32 Stock-based Compensation Expense Stock-based compensation expense for equity and liability classified awards is recognized using the straight-line attribution method. In addition, the Company ensures that it has fully recognized expense for at least the options tranches that have fully vested in the period in which they vest. Stock-based compensation expense is summarized as follows (in thousands), including expense in connection with liability classified awards: Year ended December 31, 2021 2020 2019 Cost of revenue $ 1,410 $ 430 $ 519 Sales and marketing 7,843 5,199 5,382 Research and development 6,447 4,140 4,325 General and administrative 9,356 7,926 8,607 Total stock-based compensation expense $ 25,056 $ 17,695 $ 18,833 Common Stock Valuations As we are now a public company, we have a readily determinable market price for our common stock, which we will utilize in determining the fair value of any future awards. Prior to the Reverse Recapitalization Transaction, the fair value of the common stock underlying the stock options was determined by the board of directors, which intended all options granted to be exercisable at a price per share not less than the per share fair value of the common stock underlying those options on the date of grant. Because there was no public market for our common stock, the valuations of the common stock were determined in accordance with the guidelines outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation and Internal Revenue Service Revenue Ruling 59-60. • contemporaneous independent valuations performed at periodic intervals by an unrelated third-party valuation specialist; • the nature of the business and its history since inception; • the economic outlook in general and the condition and outlook of the specific industry; • the book value of the stock and the financial condition of the business; • the operating and financial performance and forecast; • whether or not the Company has goodwill or other intangible values; • marketability of the common stock; • the hiring of key personnel; • any corporate or asset acquisitions, or divestitures; • present value of estimated future cash flows; • the likelihood of achieving a liquidity event for the shares of common stock underlying these stock options, such as an initial public offering or sale of the company, given prevailing market condition and the nature and history of the business; • illiquidity of stock-based awards involving securities in a private company; • the market performance of comparable publicly traded technology companies; and • the U.S. and global capital market conditions. As noted above, as of December 31, 2021, no nonqualified stock options had been granted pursuant to the 2021 Equity Incentive Plan. 2017 Long-Term Incentive Plan On May 26, 2017, the Board of Directors of the Company’s ultimate parent, Papay Topco, Inc., approved a Long-Term Incentive Plan (the “2017 LTI Plan”) to provide incentives to its employees of Cvent, Inc. The 2017 LTI Plan provides for the payment of a cash bonus if the Company is sold, or another similar Qualifying Event occurs. The incentive approved through the 2017 LTI Plan remains unvested until a sale of the Company, or other Qualifying Event occurs. A Qualifying event is defined as any sale or transfer to any third party of at least 50% of the investor’s equity interest. If the Company is sold, or another Qualifying Event occurs, the amount of the cash bonus will vary based on the total purchase price. Specifically, the LTI cash bonus payment will only occur if each and every of the following events occur: a) the Company is sold, or another Qualifying Event occurs; b) the Company is sold for an Equity Return Multiple of at least 2 times Equity initially invested by Vista Equity Partners Fund VI, L.P., (“Fund VI”); and c) the respective employee remains employed at the time of the sale. The Company recorded no expense for the 2017 LTI Plan for the years ended December 31, 2021, 2020, and 2019 because the incentive remains unvested and the Company is only liable to make the LTI cash bonus payments upon a sale of the Company, or other Qualified Event, which is not currently determined to be probable. The liability and related expense will be recorded at the point in time that a Qualified Event becomes probable. As of December 31, 2021, these awards were not considered probable of meeting the vesting requirements and accordingly, no expense was recorded during the year ended December 31, 2021 and the timing of when this expense will be recognized was unknown. On February 28, 2022, the Compensation and Nominating Committee of the Board approved a plan that allows employees to convert their awards (the “Legacy Cvent LTIP Awards”) granted under the 2017 LTI Plan to an aggregate of approximately 3.7 million RSUs in exchange for cancellation of such employees outstanding Legacy Cvent LTIP Awards. The RSUs are subject to varying vesting periods ranging from April 2022 to October 2024. The RSUs will be granted effective as of April 15, 2022 to employees who elect to participate in such exchange.

Retirement Plans	12. Retirement Plans a) 401(k) Retirement Savings Plan In 2021, 2020 and 2019, Cvent provided a 401(k) Retirement Savings Plan (the “Plan”) to eligible employees in the United States, which were subject to certain minimum age and period of service restrictions. The Plan provides for discretionary contributions from Cvent related to a calendar year ending December 31, on or before February 28 of the next calendar year. The Company matches 50% of employee contributions up to 6% of their earnings, subject to a $3,500 U.S. dollar limit per employee. Company contributions were $4.5 million, $2.1 million, and $3.6 million, respectively, during the years ended December 31, 2021, 2020, and 2019, respectively. Cvent contributions to its Plan in the United States are accrued during the calendar year and paid out following the end of the year. At the beginning of 2020, Cvent started funding the employer match on a monthly basis based on the same contribution scheme described above and maintained this approach through April 2020. However, starting in June 2020, because of the global COVID-19 The Company maintains other defined contribution plans where activity is immaterial. b) India Gratuity Plan Under the India Payment of Gratuity Act of 1972, the Company maintains a gratuity defined-benefit plan for eligible employees of the Company’s India subsidiary. Upon termination of an employee for any reason, the Company must pay the equivalent of 15 days of the current salary to the employee for each year of service if the employee has vested in the plan. Benefits accrue based on all eligible employees regardless of their respective vesting schedule upon their date of hire. The accrual calculation includes an estimate for the number of employees who will not meet their vesting requirements. Eligible employees vest upon reaching five years of service with the Company. The funding liability under the plan was determined by licensed actuarial professionals, based on a rate of interest of 5.8% and 4.9% and a retirement age of 58 years, and was $2.9 million and $2.4 million as of December 31, 2021 and 2020, respectively. The liability is included in accrued and other current liabilities in the accompanying consolidated balance sheets. Expense under the plan was $0.8 million, $0.6 million, and $0.6 million for the years ended December 31, 2021, 2020 and 2019, respectively. The plan is currently unfunded.

Debt The outstanding principal amount and related unamortized debt issuance costs, net, are summarized as follows (in thousands): As of December 31, 2021 2020 First Lien Principal amount $ 265,696 $ 771,648 Revolving Credit Facility Principal Amount — 13,400 Less: original issue discount (438 ) (1,702 ) Less: unamortized deferred financing costs (2,956 ) (11,473 ) Total principal amount and related unamortized debt issuance costs, net $ 262,302 $ 771,873 a) First Lien As of January 1, 2019, the Company had a $787.5 million variable rate first lien loan, or Term Loan Facility, with a consortium of lenders (including Vista Credit Partners) and Goldman Sachs acting as the administrative agent with a maturity date of November 30, 2024. The Company can elect Eurodollar Borrowings six-month The Company can elect the interest rate at the time the previous election matures, and the accrued interest is due. If an election is not made, then the prior interest election remains in effect. The Financial Conduct Authority in the United Kingdom (“U.K.”) has stated it plans to phase out LIBOR by the end of calendar year 2021. The Company does not anticipate a significant impact to our financial position or results of operations as we expect our agreements to be modified utilizing a similar rate before phase out occurs. The principal amount of the Term Loan Facility amortizes in quarterly installments equal to $ million, due on the last business day of the quarter with a balloon payment at the end of the term ending on November 30, 2024. The quarterly principal payment due may be adjusted from time to time to reflect voluntary and mandatory prepayments with the balance payable at maturity. In addition, the Company remits an administrative agent fee to Goldman Sachs in the amount and at the time agreed upon between the Company and the lenders. The interest rate on outstanding borrowings under the first lien was % as of December 31, 2021. The carrying value of variable rate debt approximates fair value due to the short-term nature of the interest rates. With respect to the Term Loan Facility, mandatory prepayments are required upon certain events including: 1) net cash proceeds from certain asset sales that meet the requirements contained in the debt agreement, 2) net cash proceeds from debt issuances that are not permitted under the credit agreements or 3) a prepayment related to the Company’s Excess Cash Flow. Excess Cash Flow is defined in the Company’s first lien credit agreement with Goldman Sachs. Excess Cash Flow is defined as Consolidated EBITDA(as defined in the agreement governing the Term Loan Facility) minus certain items, including, but not limited to, a) debt service, b) capital expenditures, c) consolidated tax expense paid in cash, d) cash paid for permitted acquisitions, e) negative changes in working capital, and f) various other items. The Excess Cash Flow prepayment calls for a payment based on the percentage of Excess Cash Flow recognized for the period that exceeds $7.5 million. The percentage of excess cash that must be used to prepay the loan varies based on the first lien leverage ratio, as defined in the credit agreement, at that time. The prepayment is reduced dollar for dollar for any voluntary prepayments, buybacks or forced retirements made during the year. There was no Excess Cash Flow payment due for the years ended December 31, 2021 and 2020. The first lien is prepayable at any time subject to the call provisions in the loan agreement. As previously discussed in Note 1, during the fourth quarter the Company completed our Reverse Recapitalization Transaction with Dragoneer. Net proceeds from this transaction after deducting fees and expenses were approximately $523.0 million, $500.0 million of which was used to repay the outstanding principal indebtedness under our Term Loan Facility. As a result of the voluntary prepayment of the outstanding principal indebtedness under our Term Loan Facility, the company recognized $7.2 million in loss on extinguishment of debt reflected in the Company’s consolidated statement of operations associated with the write-off Future minimum principal payments under the debt agreement as of December 31, 2021 are as follows (in thousands): 2022 $ — 2023 — 2024 265,696 Total minimum principal payments on debt $ 265,696 b) Revolving Credit Facility The Company has an agreement for a variable rate revolving credit facility in the amount of $40.0 million, which has a maturity date of November 29, 2021. In April 2021, the Company amended and extended this COVID-19 one-month c) Letters of Credit The Company has letters of credit with Bank of America and Goldman Sachs, for the purposes of securing leased space to support our global operations. The letter of credit with Bank of America is secured by cash in the amount of $0.1 million that we classify as restricted cash on the consolidated balance sheets. The Goldman Sachs letter of credit is backstopped against the Company’s revolving credit facility.

The Company has no direct outstanding debt obligations. However, Cvent, Legacy Cvent and Papay Holdco, LLC (“Holdco”), each a wholly-owned subsidiary of the Company, are limited in their ability to declare dividends or make any payment on account of its capital stock to, directly or indirectly, fund a dividend or other distribution to the Company as a borrower and a parent guarantor, respectively, under the Company’s Credit Facilities, subject to limited exceptions, including, as of December 31, 2021, (1) certain stock repurchases subject to customary limitations and exceptions, (2) up to the greater of $55,000,000 and 35.0% of consolidated EBITDA (as defined in the agreement governing the Term Loan Facility) tested based on the four consecutive fiscal quarters of Holdco then last ended, subject to customary limitations and exceptions, (3) unlimited amounts subject to compliance with a 4.50 to 1.00 first lien net leverage ratio giving pro forma effect to any distribution, (4) unlimited amount up to 7% per annum of the market capitalization following the consummation of an IPO, and (5) payment of the Company’s overhead expenses.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited interim condensed consolidated financial statements as of March 31, 2022 and for the three months ended March 31, 2022 and 2021 include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting primarily of normal recurring accruals, necessary for a fair statement of the financial position as of March 31, 2022, the results of operations for the three months ended March 31, 2022 and 2021, and cash flows for the three months ended March 31, 2022 and 2021. The condensed balance sheet at December 31, 2021 was derived from audited annual financial statements and does not contain all of the footnote disclosures from the annual financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K	Basis of Presentation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”). The Reverse Recapitalization Transaction between Dragoneer and Legacy Cvent was accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Dragoneer was treated as the acquired company and Legacy Cvent was treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the Reverse Recapitalization Transaction was treated as the equivalent of Legacy Cvent issuing stock for the net assets of Dragoneer, accompanied by a recapitalization. The net assets of Dragoneer are stated at historical cost, with no goodwill or other intangible assets recorded. Legacy Cvent was determined to be the accounting acquirer based on the following predominant factors: • Legacy Cvent’s existing stockholders had a majority of the voting power in the Company following the Reverse Recapitalization Transaction; • Legacy Cvent had the ability to nominate a majority of the initial members of our Board; • Legacy Cvent’s senior management is the senior management of the Company; • Legacy Cvent’s operations prior to the Reverse Recapitalization Transaction comprised the ongoing operations of the Company; • Legacy Cvent is the larger entity based on historical operating activity and had the larger employee base prior to the Reverse Recapitalization Transaction; and • The post-combination company assumed a Legacy Cvent branded name: “Cvent Holding Corp.” The consolidated assets, liabilities and results of operations prior to the Reverse Recapitalization Transaction are those of Legacy Cvent. The shares and corresponding capital amounts and losses per share, prior to the Reverse Recapitalization Transaction, have been retroactively restated based on shares reflecting the exchange ratio established in the Reverse Recapitalization Transaction of approximately 454:1, with the exception of the authorized shares and shares reserved for issuance. See Note 3. Reverse Recapitalization Transaction for more information.
Use of Estimates		Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions made by management include estimated useful lives of property and equipment, capitalized software development costs, capitalized sales commissions, the valuation of goodwill and intangibles, allowances for doubtful accounts, valuation of deferred tax assets, certain assumptions related to stock-based compensation, including the estimated value of the Company’s common stock and, income taxes. As of the date the financial statements were available for issuance, we are not aware of any specific events or circumstances that would require us to update our estimates, judgments, or to revise the carrying values of our assets or liabilities. Actual results could differ from those estimates and assumptions.
Cash and Cash Equivalents		Cash and Cash Equivalents Highly liquid financial instruments purchased with original maturities of or less at the date of purchase are reported as cash equivalents. Cash equivalents are recorded at cost, which approximates fair value due to their short-term maturities. Included in cash and cash equivalents are funds representing amounts reserved for registration fees processed on behalf of customers. While these cash accounts are not restricted as to their use, a liability for amounts due to customers under these arrangements has been recorded in Fees payable to customers in the accompanying consolidated balance sheets. Fees payable to customers were $25.0 million and $16.9 million as of December 31, 2021 and 2020, respectively.
Restricted Cash	Restricted Cash Restricted cash represents amounts required to be held as collateral in a money market account for treasury management service agreements. The Company held $0.1 million of restricted cash as of March 31, 2022 and December 31, 2021.

Short-term Investments		Short-term Investments All highly liquid investments with stated maturity dates between three months and one year from the purchase date are classified as short-term investments. The Company determines the appropriate classification of its short-term investments at the time of purchase. The Company’s short-term investments consist of highly liquid financial instruments, which are comprised of certificates-of-deposit,
Accounts Receivable		Accounts Receivable Accounts receivable includes billed and unbilled receivables, net of allowance for credit losses. Accounts receivable are recorded at the amount invoiced to customers and do not bear interest. The Company estimates the allowance for expected credit loss based on collectability of accounts receivable and unbilled receivables by considering various factors, including the age of the accounts receivable balances, historical write-off Year Ended December 31, 2021 2020 2019 Allowance for expected credit losses, beginning of period $ 3,287 $ 1,912 $ 3,379 Credit loss expense 8,316 3,280 1,407 Write-offs and adjustments (7,056 ) (1,905 ) (2,874 ) Allowance for expected credit losses, end of period $ 4,547 $ 3,287 $ 1,912 off-balance
Revenue Recognition	Revenue Recognition The Company derives revenue from two primary sources: Event Cloud subscription-based solutions and Hospitality Cloud marketing and subscription-based solutions. Subscription services revenue consists primarily of fees to provide the Company’s customers with access to its cloud-based platform. Subscription service contracts do not provide customers with the right to take possession of the software, are non-cancellable,	Revenue Recognition The Company derives revenue from two primary sources: Event Cloud subscription-based solutions and Hospitality Cloud marketing and subscription-based solutions. Subscription services revenue consists primarily of fees to provide the Company’s customers with access to its cloud-based platform. Subscription service contracts do not provide customers with the right to take possession of the software, are non-cancellable, Certain contracts may include multiple distinct performance obligations which may consist of some or all of subscription services, marketing packages, and professional services. When an arrangement includes multiple performance obligations relating to SaaS subscriptions, which are Revenue from services transferred to the customer on currently delivered and have the same pattern of transfer to the customer (the services transfer to the customer ratably over the contract period), the entire contract value is recognized on a straight-line basis over the contract term. When an arrangement includes multiple performance obligations that do not have the same pattern of transfer to the customer, revenue is recognized at each performance obligation’s respective standalone selling price (“SSP”), when the performance obligations are satisfied. The SSP is the price at which the Company would sell a promised good or service separately to a customer. The Company estimates SSP based on internal margin analysis, competitor data, and other industry standards for SaaS-based companies. Event Cloud Revenue Event Management The Company generates the majority of its Event Cloud revenue through four primary sources: 1) Software-as-a-Service in-person, Event and Conference Management Platform SaaS subscriptions to the event and conference management platforms may include functionality that enables customers to manage the registration of people that plan to attend the customer’s event or events. At any time during the subscription term, customers may elect to purchase blocks of additional registrations (“reg blocks”) and other features or functionality (“non-reg”), transaction price of the original contract. Accordingly, a cumulative revenue catch-up Non-reg non-reg Attendee Hub and Mobile Apps Subscription-based solutions also include the sale of mobile event apps for in-person, Onsite Event Solutions Event specific onsite solutions include the rental of equipment and consultants needed to successfully manage and execute a complex event, along with the SaaS to manage appointments, exhibitors, speakers, and lead capture and to aggregate all of this information to understand attendee interests. Revenue related to rental of equipment and consultants is recognized based on the contractual stated value, which approximates its relative standalone selling price, and is generally recognized at a point in time as the services are performed and the performance obligations are satisfied. Revenue related to the Company’s SaaS subscriptions to its onsite solutions are considered a service arrangement and recognized to revenue over time, on a straight-line basis over the term of the subscription arrangement. Hospitality Cloud Revenue The Hospitality Cloud offers cloud-based SaaS solutions to drive increased demand across the hotel group sales lifecycle from advertising to lead management tools. Group Marketing Solutions Group marketing solutions revenue is generated through the delivery of various forms of advertising sold through annual or multi-year contracts to hotels and venues. Advertising is sold as a stand ready obligation to deliver advertising, and accordingly revenue is recognized over time on a straight-line basis as the performance obligation is satisfied and the advertisement is displayed. Such solutions include prominent display of a customer’s venue within the Cvent Supplier Network to find and book physical event space. Pricing for the advertisements is based on the term of the advertisement, targeted geography, market tier, number of advertisements and prominence of the ad placement. Cloud-Based SaaS Solutions The Hospitality Cloud also offers a variety of cloud-based SaaS solutions such as 1) Passkey, which allows hotels, convention and visitor bureaus and meeting management companies to streamline and automate hotel room blocks; hotels also use Passkey to create upsell opportunities with group guests, who in turn gain a simpler way to make and manage their hotel reservations. 2) Business Transient, which simplifies how hotels attract, manage and win corporate travel business, publish data to Global Distribution Systems and online travel agency websites, and 3) Event Diagramming, a collaborative SaaS tool that empowers event planners and venues to work together to design the
Leases		Leases The Company determines whether an arrangement is or contains a lease at contract inception, and arrangements meeting the definition of a lease are classified as operating or financing leases at the lease commencement date. For leases with an original term longer than twelve months, lease liabilities are initially recognized on the lease commencement date based on the present value of the future minimum lease payments over the lease term. A corresponding right-of-use non-lease non-lease non-cancellable
Deferred Revenue		Deferred Revenue Deferred revenue consists of contractual billings made for which the contract start date has passed or where payments have been received in advance of revenue recognition from Event Cloud solutions or Hospitality Cloud solutions. The Company generally invoices customers in annual or quarterly installments. Customer invoices are generally due 30 days from the time of invoicing. The Company does not have significant financing components in its contracts as the Company expects to receive full payment for its services within one year from the date of transfer of services to customers.
Cost of Revenue		Cost of Revenue Cost of revenue primarily consists of employee-related expenses, including salaries, benefits, bonuses and stock-based compensation, related to providing support and hosting our applications, costs of cloud-based data center capacity, software license fees, costs to support our onsite solutions and virtual products, interchange fees related to merchant services and amortization expense associated with capitalized software. In addition, we allocate a portion of overhead, such as rent and depreciation and amortization to cost of revenue based on headcount.
Property and Equipment		Property and Equipment Property and equipment is stated at cost less accumulated depreciation and amortization. Improvements and replacements of property and equipment are capitalized. Maintenance and repairs that do not improve or extend the lives of property and equipment are charged to expense as incurred. When assets are sold or retired, their cost and related accumulated depreciation are removed from the ledger and any gain or loss is reported in operating loss in the accompanying consolidated statements of operations and comprehensive loss. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. The estimated useful life of computer equipment and purchased software is three years while the estimated useful lives of furniture and equipment is seven years. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or estimated useful life of the asset.
Capitalized Software Development Costs		Capitalized Software Development Costs Costs incurred during the application development stage to develop software directly used in the delivery of revenue generating activities are capitalized and recorded as capitalized software development costs on the consolidated balance sheet in accordance with the provisions of FASB ASC Subtopic 350-40, Intangibles – Goodwill and Other Subtopic 40 Internal-Use on a project-by-project basis in the application development stage. project-by-
Impairment of Long-Lived Assets		Impairment of Long-Lived Assets Long-lived assets are reviewed for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. If such review indicates that the carrying amount of long- lived assets is not recoverable from future undiscounted cash flows, the carrying amount of such assets is reduced to the lower of the carrying value or fair value. In addition to the recoverability assessment, the Company routinely reviews the remaining estimated lives of its long-lived assets. Any reduction in the useful life assumption will result in increased depreciation and amortization expense in the period when such determinations are made, as well as in subsequent periods. There was no change to the useful lives of long-lived assets for the years-ended December 31, 2021 and 2020.
Goodwill		Goodwill Goodwill represents the excess of: (i) the aggregate of the fair value of consideration transferred in a business combination, over (ii) the fair value of assets acquired, net of liabilities assumed. Goodwill is not amortized but is subject to annual impairment tests. The Company adopted Accounting Standards Update No 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment The Company performs an annual impairment review of goodwill, or when a triggering event occurs between annual impairment tests. The Company operates as one reporting unit. The Company’s test for goodwill impairment
Research and Development		Research and Development Research and development expenses consist primarily of personnel and related expenses for our research and development staff, including salaries, benefits, bonuses and stock-based compensation and the cost of third-party contractors. Research and development expenses, other than software development costs that qualify for capitalization, are expensed as incurred. In addition, we allocate a portion of overhead, such as rent and depreciation to research and development based on headcount.
Sales Commissions		Sales Commissions Commissions earned by the Company’s sales personnel are considered incremental costs of obtaining a contract with a customer. Accordingly, sales commissions are capitalized when incurred and amortized on a straight-line basis over the Company’s average historical customer life, which is determined based on the underlying product line and ranges from one four by reviewing the average length of its customers contracts, changes in technology, expected contract renewals and customer retention, and other industry factors. The Company re-assesses The current portion of capitalized commissions, net was $25.4 million and $22.0 million as of December 31, 2021 and 2020, respectively. The noncurrent portion of capitalized commissions, net was $23.0 million and $20.4 million as of December 31, 2021 and 2020, respectively. During the years ended December 31, 2021, 2020, and 2019, $29.3 million, $29.1 million, and $25.6 million, respectively, of capitalized commissions were amortized to sales and marketing expense in the accompanying consolidated statements of operations and comprehensive loss.
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 the existing assets and liabilities, and their respective income 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. The Company establishes a valuation allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. The Company only recognizes the tax benefit from an uncertain tax position if it is more likely than not that the tax position will be sustained on examination. The Company is subject to tax on global intangible low-taxed
Stock-Based Compensation		Stock-Based Compensation Employee stock-based compensation is recognized as a cost in the consolidated statements of operations and comprehensive loss. For both equity-classified and liability-classified awards, such cost is measured at the grant date fair value of the award. We estimate the grant date fair value for stock options using the Black-Scholes option-pricing model. The Black-Scholes pricing model requires the use of subjective assumptions including the expected term of the options, the price volatility of the underlying stock, dividend yield, and a discount for the lack of marketability. The expected dividend yield is zero, as we have not previously declared cash dividends and do not currently intend to declare cash dividends in the foreseeable future. Prior to the Company becoming publicly traded, because we were privately-held, the Black-Scholes pricing inputs, including the grant date fair value of the underlying common stock, volatility of the underlying stock, and a discount for the lack of marketability, were estimated based on our peer group companies, which are publicly-traded. Our peer group was established through consultation with our external valuation firm; our ultimate parent entity, an affiliate of Vista Equity Partners Management, LLC (“Vista”); and confirmed through the review of the performance and valuation attributes of our peer group to determine that our public-company peer group is a reasonable and fair proxy for our share performance, if our shares were publicly-traded. The risk-free rate for the expected term of the option was based on the U.S. Treasury yield curve at the date of grant.
Comprehensive Loss		Comprehensive Loss Comprehensive loss comprises net loss and foreign currency translation gains/(losses) for the years ended December 31, 2021, 2020, and 2019, respectively.
Foreign Currency		Foreign Currency The Company’s foreign subsidiary in India designates the U.S. dollar as its functional currency. For this subsidiary, assets and liabilities denominated in currencies other than the U.S. dollar are remeasured into U.S. dollars at current exchange rates for monetary assets and liabilities and historical exchange rates for non-monetary The functional currency for certain of the Company’s other foreign subsidiaries is the local currency. For those subsidiaries, the assets and liabilities are translated into U.S. dollars at exchange rates in effect as of the balance sheet date. Revenue and expense items are translated based on average exchange rates for the period. Foreign currency (gains)/losses associated with realized transactions and remeasurement, recorded in other income/(expense), net, were $(0.8) million, $0.8 million, and $1.5 million for the years ended December 31, 2021, 2020, and 2019 respectively.
Non-Monetary Transactions		The initial determination of compensation cost is based on the number of stock options or other awards granted, which is then amortized over the vesting period. Liability classified awards are remeasured to fair value at each reporting date with the corresponding change in value recorded in the consolidated statements of operations and comprehensive loss. The Company recognizes expense over the requisite service period on a straight-line basis. The Company records the impact of forfeitures on stock compensation expense in the period the forfeitures occur. Comprehensive Loss Comprehensive loss comprises net loss and foreign currency translation gains/(losses) for the years ended December 31, 2021, 2020, and 2019, respectively. Foreign Currency The Company’s foreign subsidiary in India designates the U.S. dollar as its functional currency.

Revenue and expense items are translated based on average exchange rates for the period. Foreign currency (gains)/losses associated with realized transactions and remeasurement, recorded in other income/(expense), net, were $(0.8) million, $0.8 million, and $1.5 million for the years ended December 31, 2021, 2020, and 2019 respectively. Non-Monetary The Company occasionally participates in non-monetary Non-monetary Non-monetary Non-monetary
Fair Value Measurements		Fair Value Measurements Fair value represents the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on the following three levels of inputs, of which the first two are considered observable and the last one is considered unobservable: Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 Inputs: Unobservable inputs that require the Company to use present value and other valuation techniques in the determination of fair value. The Company’s financial instruments include cash and cash equivalents, restricted cash, short-term investments, accounts receivable, accounts payable and accrued liabilities. The carrying value of these financial instruments on the consolidated balance sheets approximate their fair value based on their short-term maturities.
Debt Issuance Costs		Debt Issuance Costs Costs incurred with lenders and other third parties that are specific and incremental costs required to obtain debt are amortized as interest expense over the life of the debt using the effective interest method. Unamortized debt issuance costs are presented as a direct reduction of the carrying value of the related debt.

Net Loss per Share of Common Stock	Net Loss per Share of Common Stock Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share adjusts basic earnings per share for the potentially dilutive impact of stock options. As the Company has reported losses for all periods presented, all potentially dilutive securities, including stock options, are antidilutive and accordingly, basic net loss per share equals diluted net loss per share. For the three months ended March 31, 2022 and 2021, 55,354,536 and 36,768,058 stock options were excluded from the computation of diluted net loss per share of common stock, respectively, because including them would have been antidilutive.
