Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The accompanying consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these Notes to Consolidated Financial Statements. Principles of Consolidation The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, TechTarget Securities Corporation (“TSC”), TechTarget Limited, TechTarget (HK) Limited (“TTGT HK”), TechTarget (Australia) Pty Ltd., TechTarget (Singapore) Pte Ltd., E-Magine Médias SAS (“LeMagIT”), TechTarget Germany GmbH and as of December 23, 2020, BrightTALK Limited and its wholly owned subsidiary, BrightTALK, Inc. (“BrightTALK”). TSC is a Massachusetts corporation. TechTarget Limited is a subsidiary doing business principally in the United Kingdom.

BrightTALK are entities which the Company does business for the BrightTALK webinar and virtual event platform. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenues, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals, the allocation of purchase price to intangibles and goodwill, and income taxes. Estimates of the carrying value of certain assets and liabilities are based on historical experience and on various other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates. Revenue Recognition under ASC 606, Revenue from Contracts with Customers (“ASC 606”) The Company generates its revenues from the sale of targeted marketing and advertising campaigns, which it delivers via its data analytic solutions. Revenue is recognized when performance obligations are satisfied by transferring promised goods or services to customers, as determined by applying a five-step process consisting of: a) identifying the contract, or contracts, with a customer, b) identifying the performance obligations in the contract, c) determining the transaction price, d) allocating the transaction price to the performance obligations in the contract, and e) recognizing revenue when, or as, performance obligations are satisfied. The Company’s offerings consist of: • IT Deal Alert™ . A suite of data, software and services for B2B technology companies that leverages the detailed purchase intent data we collect on enterprise technology organizations and professionals researching IT purchases via our network of websites and our webinar community platform. Through our proprietary data-capture and scoring methodologies, we use this insight to help our customers identify and prioritize accounts and contacts whose content consumption and online research activities around specific enterprise technology topics indicate they are “in-market” for a particular B2B technology product or service. The suite of products and services includes Priority Engine™ and Qualified Sales Opportunities™. Priority Engine™ is a subscription service powered by our Activity Intelligence™ platform, which integrates with customer relationship management (“CRM”) and marketing automation platforms (“MAPs”) including Salesforce.com, Marketo, Hubspot, Eloqua, Pardot, and Integrate. The service delivers lead generation workflow solutions designed to enable marketers and salesforces to identify and prioritize accounts and individuals actively researching new technology purchases or upgrades, and then to engage those active prospects. We launched IntentMail AI TM in December 2023, which is Priority Engine’s AI-powered messaging feature, which enables sellers to automatically generate personalized email copy. Qualified Sales Opportunities™ is a product that profiles specific in-progress purchase projects via surveys and interviews with business technology professionals whose research activity and content consumption is indicative of a pending technology purchase. Qualified Sales Opportunities™ include information on project scope, purchase criteria and vendors considered. • Demand Solutions. Our offerings enable our customers to reach and influence prospective buyers through content marketing programs, such as white papers, webcasts, podcasts, videocasts, virtual trade shows, and content sponsorships, designed to generate demand for their solutions, and through display advertising and other brand programs that influence consideration by prospective buyers.

Revenue from demand and brand solutions is primarily recognized when the transfer of control occurs. Certain of the contracts within demand and brand solutions are duration-based campaigns which, in the event of customer cancellation, provide the Company with an enforceable right to a proportional payment for the portion of the campaign based on services provided. Accordingly, revenue from duration-based campaigns is recognized using a time-based measure of progress, which the Company believes best depicts how it satisfies its performance obligations in these arrangements as control is continuously transferred throughout the contract period. Revenue from custom content creation is recognized over the expected period of performance using a single measure of progress, typically based on hours incurred. Revenue from Priority Engine™ and the Bright TALK platform are recognized over a time-based measure of progress, which the Company believes best depicts how it satisfies its performance obligations in these arrangements as control is continuously transferred throughout the contract period. To determine standalone selling price for the individual performance obligations in the arrangement, the Company uses an estimate of the observable selling prices in separate transactions. The Company establishes best estimates considering multiple factors including, but not limited to, class of client, size of transaction, available inventory, pricing strategies and market conditions. The Company uses a range of amounts to estimate stand-alone selling price when it sells the goods and services separately and needs to determine whether a discount is to be allocated based upon the relative stand-alone selling price to the various goods and services. Judgment is required to determine the standalone selling price for each distinct performance obligation. Fair Value of Financial Instruments Financial instruments consist of cash, cash equivalents, short-term investments, accounts receivable, accounts payable, long-term debt and contingent consideration. Due to their short-term nature and liquidity, the carrying value of these instruments, with the exception of contingent consideration and long-term debt, approximates their estimated fair values. See Note 4 for further information on the fair value of the Company’s investments. The Company classifies all of its short-term investments as available-for-sale. The fair value of contingent consideration was estimated using a discounted cash flow method. Business Combinations The Company uses its best estimates and assumptions to assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. The Company’s estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions and tax-related valuation allowances are initially recorded in connection with a business combination as of the acquisition date. The Company continues to collect information and reevaluates these estimates and assumptions quarterly and records any adjustments to the Company’s preliminary estimates to goodwill provided that the Company is within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s consolidated statement of operations. Long-Lived Assets , Goodwill and Indefinite-lived Intangible Assets Long-lived assets consist primarily of property and equipment, capitalized software, goodwill and other intangible assets. The Company reviews long-lived assets, including property and equipment and finite intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Conditions that would trigger an impairment assessment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of an asset or an adverse action or a significant decrease in the market price. A specifically identified intangible asset must be recorded as a separate asset from goodwill if either of the following two criteria is met: (1) the intangible asset acquired arises from contractual or other legal rights; or (2) the intangible asset is separable. Accordingly, intangible assets consist of specifically identified intangible assets. Goodwill is the excess of any purchase price over the estimated fair value of net tangible and intangible assets acquired. Goodwill and indefinite-lived intangible assets are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Separable intangible assets that are not deemed to have an indefinite life are amortized over their estimated useful lives, which range from eighteen months to nineteen years , using methods of amortization that are expected to reflect the estimated pattern of economic use, and are reviewed for impairment when events or changes in circumstances suggest that the assets may not be recoverable. Consistent with the Company’s determination that it has a single reporting segment, it has been determined that there is a single reporting unit and goodwill is therefore tested for impairment at the entity level. The Company performs its annual test of impairment of goodwill as of December 31st of each year and whenever events or changes in circumstances suggest that the carrying amount may not be recoverable using the two-step process required by ASC 350, Intangibles – Goodwill and Other (“ASC 350”). The first step of the impairment test is to identify potential impairment by comparing the reporting unit’s fair value with its net book value (or carrying amount), including goodwill. The fair value is estimated based on a market value approach. If the fair value of the reporting unit exceeds its carrying amount, the reporting unit’s goodwill is not considered to be impaired and the second step of the impairment test is not performed. Whenever indicators of impairment become present, the Company would perform the second step and compare the implied fair value of the reporting unit’s goodwill, as defined by ASC 350, to it carrying value to determine the amount of the impairment loss, if any. As of December 31, 2023, there were no indications of impairment based on the step one analysis, and the Company’s estimated fair value exceeded its goodwill carrying value by a significant margin. Based on the aforementioned evaluation, the Company believes that, as of the balance sheet date presented, none of the Company’s goodwill or other long-lived assets were impaired. The Company did no t have any intangible assets, other than goodwill, with indefinite lives as of December 31, 2023 or 2022 . Allowance for Doubtful Accounts The Company reduces gross trade accounts receivable for an allowance for doubtful accounts. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in its existing accounts receivable. The allowance for doubtful accounts is reviewed on a regular basis, and all past due balances are reviewed individually for collectability. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Provisions for doubtful accounts are recorded in general and administrative expense. Below is a summary of the changes in the Company’s allowance for doubtful accounts for the years ended December 31, 2023, 2022, and 2021. Balance at Provision Write-offs, Balance at Year ended December 31, 2023 $ 4,494 $ 2,021 $ ( 1,487 ) $ 5,028 Year ended December 31, 2022 $ 2,514 $ 2,239 $ ( 259 ) $ 4,494 Year ended December 31, 2021 $ 1,754 $ 904 $ ( 144 ) $ 2,514 Property and Equipment and Other Capitalized Assets Property and equipment and other capitalized assets are stated at cost. Property and equipment acquired through acquisitions of businesses are initially recorded at fair value. Depreciation is calculated on the straight-line method based on the month the asset is placed in service over the following estimated useful lives: Estimated Useful Lives Furniture and fixtures 3 - 10 years Computer equipment and software 3 years Internal-use software and website development costs 3 - 5 years Leasehold improvements Shorter of useful life or remaining duration of lease Property and equipment and other capitalized assets consist of the following: As of December 31, 2023 2022 Furniture and fixtures $ 1,300 $ 1,361 Computer equipment and software 4,678 5,393 Leasehold improvements 3,786 3,867 Internal-use software and website development costs 70,233 56,340 79,997 66,961 Less: accumulated depreciation and amortization ( 55,080 ) ( 44,454 ) $ 24,917 $ 22,507 Depreciation expense was $ 12.4 million, $ 10.0 million, and $ 7.5 million for the years ended December 31, 2023, 2022, and 2021, respectively. Repairs and maintenance charges that do not increase the useful life of the assets are charged to operations as incurred. The Company wrote off approximately $ 1.9 million , $ 2.4 million , and $ 1.0 million of assets that were no longer in service during 2023, 2022, and 2021 , respectively. Depreciation expense is classified as a component of operating expense in the Company’s results of operations with the exception of certain depreciation expense which is classified as a component of cost of goods sold. Internal-Use Software and Website Development Costs The Company capitalizes costs incurred during the development of its website applications and infrastructure as well as certain costs relating to internal-use software. The Company begins to capitalize costs to develop software and website applications when planning stage 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. Judgment is required in determining the point at which various projects enter the state at which costs may be capitalized, in assessing the ongoing value of the capitalized costs and in determining the estimated useful lives over which the costs are amortized, which is generally three years. To the extent that the Company changes the manner in which it develops and tests new features and functionalities related to its websites, assesses the ongoing value of capitalized assets, or determines the estimated useful lives over which the costs are amortized, the amount of website development costs it capitalizes and amortizes in future periods would be impacted. The estimated useful lives of costs capitalized is evaluated for each specific project. Capitalized internal-use software and website development costs are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An impairment loss would be recognized only if the carrying amount of the asset is not recoverable and exceeds its fair value. The Company capitalized internal-use software and website development costs of $ 14.2 million , $ 12.9 million , and $ 11.5 million for the years ended December 31, 2023, 2022, and 2021 , respectively. Debt Issuance Costs Costs incurred with the issuance of the Company’s convertible debt are deferred and amortized as interest expense over the term of the related convertible instrument using the effective interest method. To the extent the convertible debt is outstanding, these amounts are reflected in the consolidated balance sheets as a deduction of the convertible debt. Concentrations of Credit Risk and Off-Balance Sheet Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist mainly of cash and cash equivalents, investments and accounts receivable. The Company maintains its cash and cash equivalents and investments principally in accredited financial institutions of high credit standing. The Company routinely assesses the credit worthiness of its customers. The Company generally has not experienced any significant losses related to individual customers or groups of customers in any particular industry or area. The Company does not require collateral. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company’s accounts receivable. At December 31, 2023, 2022 and 2021 , no customer represented 10% of total accounts receivable. No single customer accounted for 10% or more of total revenues in the years ended December 31, 2023, 2022, or 2021 . Income Taxes The Company’s deferred tax assets and liabilities are recognized based on temporary differences between the financial reporting and income tax bases of assets and liabilities using statutory rates. A valuation allowance is established against net deferred tax assets if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company records a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return using a “more likely than not” threshold as required by the provisions of ASC 740-10, Accounting for Uncertainty in Income Taxes (“ASC 740”). The Company recognizes interest and penalties related to unrecognized tax benefits, if any, in income tax expense. Stock-Based Compensation The Company has stock-based employee compensation plans which are more fully described in Note 11. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized in the Consolidated Statement of Income and Comprehensive Income using the straight-line method over the vesting period of the award. The Company uses the Black-Scholes option-pricing model to determine the fair value of stock option awards. Comprehensive Income Comprehensive income includes all changes in equity during a period, except those resulting from investments by stockholders and distributions to stockholders. The Company's comprehensive income includes changes in the fair value of the Company’s unrealized gains on available for sale securities and foreign currency translation adjustments. There were no reclassifications out of accumulated other comprehensive income in the periods ended December 31, 2023, 2022, or 2021 . Foreign Currency The functional currency for each of the Company’s subsidiaries is the local currency of the country in which it is incorporated. All assets and liabilities are translated into U.S. dollar equivalents at the exchange rate in effect on the balance sheet date or at a historical rate. Revenues and expenses are translated at average exchange rates. Translation gains or losses are recorded in stockholders’ equity as an element of accumulated other comprehensive income (loss). Net Income Per Share Basic earnings per share is computed based on the weighted average number of common shares and vested restricted stock units outstanding during the period. Because the holders of unvested restricted stock units do not have non-forfeitable rights to dividends or dividend equivalents, the Company does not consider these restricted stock units to be participating securities that should be included in its computation of earnings per share under the two-class method. Diluted earnings per share is computed using the weighted average number of common shares and vested, undelivered restricted stock units outstanding during the period, plus the dilutive effect of potential future issuances of common stock relating to stock option and restricted stock unit programs using the treasury stock method. In calculating diluted earnings per share, the dilutive effect of stock options and restricted stock units is computed using the average market price for the respective period. In addition, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense of stock options and restricted stock units that are in-the-money. This results in the “assumed” buyback of additional shares, thereby reducing the dilutive impact of stock options and restricted stock units. A reconciliation of the numerator and denominator used in the calculation of basic and diluted net income per share is as follows: For the Years Ended December 31, 2023 2022 2021 Numerator: Net income $ 4,461 $ 41,609 $ 949 Denominator: Basic: Weighted average shares of common stock and vested, undelivered restricted stock units outstanding 28,327,591 29,589,000 28,434,213 Diluted: Weighted average shares of common stock and vested, undelivered restricted stock units outstanding 28,327,591 29,589,000 28,434,213 Effect of potentially dilutive shares 166,953 4,483,131 1,039,678 Total weighted average shares of common stock and vested, undelivered restricted stock units outstanding and potentially dilutive shares 28,494,544 34,072,131 29,473,891 Calculation of Net Income Per Common Share: Basic: Net income applicable to common stockholders $ 4,461 $ 41,609 $ 949 Weighted average shares of stock outstanding 28,327,591 29,589,000 28,434,213 Net income per common share $ 0.16 $ 1.41 $ 0.03 Diluted: Net income applicable to common stockholders(1) $ 4,461 $ 44,173 $ 949 Weighted average shares of stock outstanding 28,494,544 34,072,131 29,473,891 Net income per common share(2) $ 0.16 $ 1.30 $ 0.03 (1) For the year ended December 31, 2022, we excluded $ 2.6 million of amortization and interest expense relating to our convertible notes when calculating net income for diluted earnings per share. There was no such adjustment in 2023 or 2021, due to anti-dilutive nature of the add-back. (2) In calculating diluted net income per share, 1.3 million shares, 107 thousand shares, and 14 thousand shares related to outstanding stock options and unvested, undelivered restricted stock units which were excluded for the years ended December 31, 2023, 2022, and 2021 , respectively, because they were anti-dilutive. Additionally, in calculating diluted net income per share, weighted average shares includes 3.9 million shares related to the if converted basis of our convertible notes for the year ended December 31, 2022. There was no such adjustment for 2023 or 2021 due to the anti-dilutive nature of the add-back. Recent Accounting Pronouncements Recently Adopted Accounting Guidance In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2023-09. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities to disclose information about their reportable segments’ significant expenses and other segment items on an interim and annual basis. Public entities with a single reportable segment are required to apply the disclosure requirements in ASU 2023-07, as well as all existing segment disclosures and reconciliation requirements in ASC 280 on an interim and annual basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2023-07. In December 2022, the FASB issued No. ASU 2022-06, Reference Rate Reform (Topic 818): Deferral of the Sunset Date of Topic 848, which extends the period of time companies can utilize the reference rate reform relief guidance in Topic 848 to December 31, 2024. The guidance was effective upon issuance and had no material effect on the Company’s consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers,” which requires entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination as if it had originated the contracts. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption is permitted. We adopted this accounting standard update on January 1, 2023 and it had no material effect on the Company's consolidated financial statements.

Revenue	3. Revenue Disaggregation of Revenue The following table depicts the disaggregation of revenue according to categories consistent with how the Company evaluates its financial performance and economic risk. International revenue consists of international geo-targeted campaigns, which are campaigns targeted at an audience of members outside of North America. Years Ended December 31, 2023 2022 2021 North America $ 153,952 $ 189,897 $ 162,360 International 76,011 107,591 101,067 Total Revenue $ 229,963 $ 297,488 $ 263,427 Years Ended December 31, 2023 2022 2021 Revenue under short-term contracts $ 144,217 $ 174,040 $ 158,561 Revenue under longer-term contracts 85,746 123,448 104,866 Total $ 229,963 $ 297,488 $ 263,427 Contract liabilities Timing may differ between the satisfaction of performance obligations and the invoicing and collection of amounts related to the Company’s contracts with customers. Liabilities are recorded for amounts that are collected in advance of the satisfaction of performance obligations. Contract liabilities on the accompanying Consolidated Balance Sheets were $ 14.7 million and $ 27.1 million at December 31, 2023 and December 31, 2022, respectively. Additionally, certain customers may receive credits, which are accounted for as a material right. The Company estimates these amounts based on the expected amount of future services to be provided to customers and allocates a portion of the transaction price to these material rights. The Company recognizes these material rights as the material rights are exercised. The resulting amounts included in contract liabilities on the accompanying Consolidated Balance Sheets were $ 1.9 million and $ 1.9 million at December 31, 2023 and December 31, 2022, respectively. Contract Liabilities Year-to-Date Activity (in thousands) Balance at January 1, 2021 $ 15,689 Billings 278,230 Revenue Recognized ( 263,427 ) Balance at December 31, 2021 30,492 Billings 294,082 Revenue Recognized ( 297,488 ) Balance at December 31, 2022 27,086 Billings 217,598 Revenue Recognized ( 229,963 ) Balance at December 31, 2023 $ 14,721 The Company elected to apply the following practical expedients: • Existence of a Significant Financing Component in a Contract . As a practical expedient, the Company has not assessed whether a contract has a significant financing component because the Company expects at contract inception that the period between payment by the customer and the transfer of promised goods or services by the Company to the customer will be one year or less. Payment terms and conditions vary by contract type, although terms generally include requirement of payment within 30 to 90 days. In addition, the Company has determined that the payment terms that the Company provides to its customers are structured primarily for reasons other than the provision of financing to the customer. • Costs to Obtain a Contract . The Company’s revenues are primarily generated from customer contracts that are for one year or less. Costs primarily consist of incentive compensation paid based on the achievements of sales targets in a given period for related revenue streams and are recognized in the month when the revenue is earned. As a practical expedient, for amortization periods which are determined to be one year or less, the Company expenses any incremental costs of obtaining the contract with a customer when incurred. For those customer contracts greater than one year, the Company capitalizes and amortizes the expenses over the period of benefit. • Revenues Invoiced . The Company has applied the practical expedient for certain revenue streams to exclude the value of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which the Company recognizes revenue in proportion to the amount it has the right to invoice for services performed.

Fair Value Measurements	4. Fair Value Measurements The Company measures certain financial assets and liabilities at fair value on a recurring basis, including short-term investments and contingent consideration. The fair value of these financial assets and liabilities was determined based on three levels of input as follows: • Level 1. Quoted prices in active markets for identical assets and liabilities; • Level 2. Observable inputs other than quoted prices in active markets; and • Level 3. Unobservable inputs. The fair value hierarchy of the Company’s financial assets and liabilities carried at fair value and measured on a recurring basis is as follows: Fair Value Measurements at December 31, 2023 Quoted Prices Significant Significant Assets: Time deposits (1) $ 25,877 $ — $ 25,877 $ — Pooled bond funds 73,724 — 73,724 — Total Short Term Investments $ 99,601 $ — $ 99,601 $ — Fair Value Measurements at December 31, 2022 Quoted Prices Significant Significant Assets: Pooled bond funds $ 20,210 $ — $ 20,210 $ — Total short-term investments $ 20,210 $ — $ 20,210 $ — Liabilities: Contingent consideration - current (2) $ 2,259 $ — $ — $ 2,259 Total liabilities $ 2,259 $ — $ — $ 2,259 (1) The Company's time deposits consist of domestic deposits which mature within nine months (Level 2). All level 2 investments are priced using observable inputs, such as quoted prices in markets that are not active and yield curves. (2) Contingent consideration liabilities are measured using the income approach and discounted to present value based on an assessment of the probability that the Company would be required to make such future payments. The contingent consideration liabilities are measured at fair value using significant Level 3 (unobservable) inputs, such as discount rates and probability measures. Remeasurement of the contingent consideration to fair value is expensed through the income statement in the period remeasured. In 2022, we recorded a decrease in amortization expense of $ 0.5 million related to the revaluation of contingent consideration. In 2021, we recorded amortization expense of $ 3.7 million related to the revaluation of contingent consideration. Contingent consideration–current is included in accrued expenses and other current liabilities on the balance sheet. The following table provides a roll-forward of the fair value of the contingent consideration categorized as Level 3 for the year ended December 31, 2023: Fair Value Balance as of December 31, 2022 $ 2,259 Payments on contingent liabilities ( 2,267 ) Amortization of discount on contingent liabilities 8 Balance as of December 31, 2023 $ —

Acquisitions	5. Acquisitions 2021 Acquisition During July 2021, the Company acquired substantially all the assets of Xtelligent Healthcare Media, LLC, a leading healthcare B2B media company focusing on healthcare-related technology for consideration of $ 24.3 million in cash after deducting $ 0.7 million for negative working capital and contingent consideration valued at $ 2.5 million. The earnouts are subject to certain revenue growth targets and the payment is adjusted based on actual results with a maximum payment of $ 5 million. The transaction was not material to the Company and the costs associated with the acquisition were not material. The Company accounted for the transaction as a business combination. In allocating the purchase consideration based on estimated fair values, the Company recorded $ 11.4 million of intangible assets and $ 16.1 million of goodwill. The majority of the goodwill balance associated with this business combination is deductible for U.S. income tax purposes .

Convertible Notes and Loan Agreement	9. Convertible Notes and Loan Agreement Convertible Notes In December 2020, the Company issued $ 201.3 million in aggregate principal amount of convertible senior notes due December 15, 2025 (“2025 Notes”) and in December 2021, the Company issued $ 414 million of aggregate principal amount of convertible senior notes due December 15, 2026 (“2026 Notes”). Further details are included below: Issuance Maturity Date Interest Rate First Interest Payment Date Effective Interest Rate Semi-Annual Interest Payment Dates Initial Conversion Rate per $1,000 Principal Initial Conversion Price Number of Shares (in millions) 2025 Notes December 15, 2025 0.125 % June 15, 2021 0.8 % June 15, and December 15 14.1977 $ 70.43 0.1 2026 Notes December 15, 2026 0.0 % –– 0.0 % –– 7.6043 $ 131.50 4.3 The 2025 Notes and the 2026 Notes (collectively, the “Notes”) are governed by indentures between the Company, as issuer, and U.S. Bank, National Association, as trustee (together, the “Indentures”). The Notes are unsecured and rank senior in right of payment to the Company’s future indebtedness that is expressly subordinated in right of payment to the Notes and equal in right of payment to the Company’s unsecured indebtedness that is not so subordinated. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election. Terms of the Notes Prior to the close of business on September 15, 2025 and September 14, 2026, the 2025 Notes and 2026 Notes, respectively, will be convertible at the option of holders during certain periods, only upon satisfaction of certain conditions set forth below. On or after September 15, 2025 (for the 2025 Notes) and September 14, 2026 (for the 2026 Notes), until the close of business on the second scheduled trading day immediately preceding the applicable maturity date, holders may convert all or any portion of their Notes at the conversion price at any time regardless of whether the conditions set forth below have been met. Holders may convert all or a portion of their Notes prior to the close of business on the day immediately preceding their respective free convertibility date described above, in multiples of the $ 1,000 principal amount, only under the following circumstances: • during any calendar quarter commencing after the calendar quarter ending on March 31, 2021 for the 2025 Notes and March 31, 2022 for the 2026 Notes (and only during such calendar quarter), if the last reported sales price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130 % of the applicable conversion price on each applicable trading day; • during the five business day period after any five consecutive trading day period, or the Notes measurement period, in which the “trading price” (as defined in each Indenture) per $ 1,000 principal amount of Notes for each trading day of the Notes measurement period was less than 98 % of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; • if the Company calls any or all of the Notes for redemption, at any time prior to the close of business on September 14, 2025 for the 2025 Notes or September 14, 2026 for the 2026 Notes; or • upon the occurrence of specified corporate events. As of December 31, 2023, the 2026 Notes and 2025 Notes are not convertible. Whether the 2026 Notes or the 2025 Notes will be convertible in the future prior to the applicable free convertibility date will depend on the satisfaction of conversion conditions contained within each series of Notes. Since the Company may elect to repay the 2026 Notes and the 2025 Notes in cash, shares of our common stock, or a combination of both, the Company has continued to classify the 2026 and the 2025 Notes as long-term debt on its consolidated balance sheet as of December 31, 2023. The Notes consist of the following as of December 31: 2023 2022 Liability Component: 2026 Notes 2025 Notes 2026 Notes 2025 Notes Principal $ 414,000 $ 3,040 $ 414,000 $ 51,381 Less: unamortized debt issuance costs 6,500 40 8,673 1,014 Net carrying amount $ 407,500 $ 3,000 $ 405,327 $ 50,367 The following table sets forth total interest expense recognized related to the Notes: Year Ended December 31, 2023 2022 2021 0.125% Coupon $ 43 $ 64 $ 240 Amortization of debt discount and transaction costs 2,400 2,500 5,364 Induced conversion expense — — 21,229 $ 2,443 $ 2,564 $ 26,833 The fair value of the Notes, which was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, quoted price of the Notes in an over-the-counter market (Level 2), and carrying value of debt instruments (carrying value excludes the equity component of the Company’s convertible notes classified in equity) were as follows: December 31, 2023 December 31, 2022 Fair Value Carrying Value Fair Value Carrying Value Convertible senior notes $ 347,087 $ 410,500 $ 361,658 $ 455,694 Based on the closing price of our common stock of $ 34.86 on December 31, 2023, the if-converted value of the 2026 Notes and 2025 Notes was less than their aggregate principal value. Partial Repurchase and Conversion of the 2025 Notes During December 2021, the Company used a portion of the proceeds from the issuance of the 2026 Notes, together with 0.8 million shares of its common stock, to repurchase and retire $ 149.9 million aggregate principal amount of the 2025 Notes, and paid accrued and unpaid interest thereon (the "2025 Notes Repurchase Transaction"). The 2025 Notes Repurchase Transaction was accounted for as an induced conversion in accordance with Accounting Standards Codification 470-20, Debt with Conversion and Other Options (ASC 470-20). The total fair value of the additional consideration to induce the conversion of $ 21.2 million was recognized as an inducement expense and classified as a component of interest expense in its consolidated statement of income. The remaining cash and common stock consideration issued under the original terms of the 2025 Notes was accounted for under the general conversion accounting guidance where the difference between the carrying amount of the 2025 Notes retired, including unamortized debt issuance cost of $ 4 million, and the cash consideration paid and the par value of the common stock issued, was recorded in additional paid-in capital. During August 2023, the Company repurchased $ 48.3 million aggregate principal amount of the 2025 Notes for $ 42.6 million including $ 0.3 million in transaction fees.

Lessee Disclosure [Abstract]
Leases and Contingencies	10. Leases and Contingencies The Company conducts its operations in leased office facilities under various noncancelable operating lease agreements that expire through December 2029. On October 26, 2017, the Company entered into a Third Amendment (the “Third Amendment”) to the lease agreement for office space in Newton, Massachusetts, dated as of August 4, 2009 (the “Newton Lease”). The Third Amendment extended the lease term to December 31, 2029 and preserves the Company’s option to extend the term for an additional five-year period subject to certain terms and conditions set forth in the Newton Lease. The Third Amendment reduced the rentable space from approximately 110,000 square feet to approximately 74,000 square feet effective January 1, 2018 . As of January 1, 2018, base monthly rent under the Third Amendment is $ 0.3 million. The base rent increases biennially at a rate averaging approximately 1 % per year, as of January 1, 2023. The Company remains responsible for certain other costs under the Third Amendment, including operating expense and taxes. In April 2021, the Company entered into a Fourth Amendment (the “Fourth Amendment”). The Fourth Amendment became effective during May 2021 . The Fourth Amendment reduced the rentable space from approximately 74,000 square feet to approximately 68,000 square feet and provided the Company with a one-time payment of approximately $ 0.6 million. As of May 1, 2021, base monthly rent is approximately $ 0.3 million per month. All other terms and conditions are substantially similar to those terms in the Third Amendment . Certain of the Company’s operating leases, including the Newton Lease, include lease incentives and escalating payment amounts and are renewable for varying periods. The Company recognizes the related rent expense on a straight-line basis over the term of each lease, taking into account the lease incentives and escalating lease payments. The Company has various non-cancelable lease agreements for certain of its offices with original lease periods expiring between 2021 and 2029. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain it will exercise that option. Leases with renewal options allow the Company to extend the lease term typically between 1 and 5 years. When determining the lease term, renewal options reasonably certain of being exercised are included in the lease term. When determining if a renewal option is reasonably certain of being exercised, the Company considers several economic factors, including but not limited to, the significance of leasehold improvements incurred on the property, whether the asset is difficult to replace, underlying contractual obligations, or specific characteristics unique to that particular lease that would make it reasonably certain that the Company would exercise such option. Renewal and termination options were generally not included in the lease term for the Company's existing operating leases. Certain of the arrangements have discounted rent periods or escalating rent payment provisions. Leases with an initial term of twelve months or less are not recorded on the consolidated balance sheets. The Company recognizes rent expense on a straight-line basis over the lease term. As of December 31, 2023 and 2022, operating lease assets were $ 17.2 million and $ 20.0 million and operating lease liabilities were $ 20.7 million and $ 24.5 million, respectively. The maturities of the Company’s operating lease liabilities as of December 31, 2023 were as follows (in thousands): Minimum Lease Years Ending December 31: Payments 2024 $ 4,963 2025 4,046 2026 3,954 2027 3,557 2028 3,401 Thereafter 3,333 Total future minimum lease payments 23,254 Less imputed interest 2,590 Total operating lease liabilities $ 20,664 Included in the condensed consolidated balance sheet: Current operating lease liabilities $ 4,049 Non-current operating lease liabilities 16,615 Total operating lease liabilities $ 20,664 For the years ended December 31, 2023, 2022 and 2021, the total lease cost is comprised of the following amounts (in thousands): December 31, 2023 December 31, 2022 December 31, 2021 Operating lease expense $ 4,204 $ 4,251 $ 4,540 Short-term lease expense 17 22 215 Total lease expense $ 4,221 $ 4,273 $ 4,755 The following summarizes additional information related to operating leases: As of December 31, 2023 Weighted-average years remaining lease term — operating leases 3.3 Weighted-average discount rate — operating leases 3.7 % If the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate as the discount rate. The Company uses its best judgment when determining the incremental borrowing rate, which is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term to the lease payments in a similar currency. Litigation From time to time and in the ordinary course of business, the Company may be subject to various claims, charges, and litigation. At December 31, 2023 and 2022 , the Company did no t have any pending claims, charges, or litigation that it expects would have a material adverse effect on its consolidated financial position, results of operations, or cash flows.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	11. Stock-Based Compensation Stock Option and Incentive Plans In April 2007, the Company’s board of directors approved the 2007 Stock Option and Incentive Plan (the “2007 Plan”), which was approved by the stockholders of the Company and became effective upon the consummation of the Company’s IPO in May 2007. The 2007 Plan allowed the Company to grant incentive stock options (“ISOs”), non-qualified stock options (“NSOs”), stock appreciation rights, deferred stock awards, restricted stock units and other awards. Under the 2007 Plan, stock options could not be granted at less than fair market value on the date of grant and grants generally vested over a three - to four-year period. Stock options granted under the 2007 Plan expire no later than ten years after the grant date. Additionally, beginning with awards made in August 2015, the Company had the option to direct a net issuance of shares for satisfaction of tax liability with respect to vesting of awards and delivery of shares. Prior to August 2015, this choice of settlement method was solely at the discretion of the award recipient. The 2007 Plan expired in May 2017 . No new awards may be granted under the 2007 Plan; however, the shares of common stock remaining in the 2007 Plan are available for issuance in connection with previously awarded grants under the 2007 Plan. There are 20,000 shares of common stock that remain subject to outstanding stock grants under the 2007 Plan as of December 31, 2023. In March 2017, the Company’s board of directors approved the 2017 Stock Option and Incentive Plan (the “2017 Plan”), which was approved by the stockholders of the Company at the 2017 Annual Meeting and became effective June 16, 2017 . The 2017 Plan replaces the Company’s 2007 Plan. On June 16, 2017, 3,000,000 shares of the Company’s common stock were reserved for issuance under the 2017 Plan and, generally, shares that are forfeited or canceled from awards under the 2017 Plan also will be available for future awards. In April 2021, the stockholders of the Company authorized the issuance of up to an additional 3,800,000 shares of the Company’s common stock under the 2017 Plan. Under the 2017 Plan, the Company may grant restricted stock and restricted stock units, non-qualified stock options, stock appreciation rights, performance awards, and other stock-based and cash-based awards. Grants generally vest in equal tranches over a three-year period. Stock options granted under the 2017 Plan expire no later than ten years after the grant date. Shares of stock issued pursuant to restricted stock awards are restricted in that they are not transferable until they vest. Shares of stock underlying awards of restricted stock units are not issued until the units vest. Non-qualified stock options cannot be exercised until they vest. Under the 2017 Plan, all stock options and stock appreciation rights must be granted with an exercise price that is at least equal to the fair market value of the common stock on the date of grant. The 2017 Plan broadly prohibits the repricing of options and stock appreciation rights without stockholder approval and requires that no dividends or dividend equivalents be paid with respect to options or stock appreciation rights. The 2017 Plan further provides that, in the event any dividends or dividend equivalents are declared with respect to restricted stock, restricted stock units, other stock-based awards and performance awards (referred to as “full-value awards”), such dividends or dividend equivalents would be subject to the same vesting and forfeiture provisions as the underlying award. There are a total of 1,745,998 shares of common stock that remain subject to outstanding stock-based grants under the 2017 Plan as of December 31, 2023. There are a total of 1,646,666 shares of common stock remain available for issuance under the 2017 Plan as of December 31, 2023. Accounting for Stock-Based Compensation The Company uses the Black-Scholes option pricing model to calculate the grant-date fair value of an award. The Company calculated the fair values of the options granted using the following estimated weighted-average assumptions: Years Ended December 31, 2023 2022 2021 Expected volatility 47 % 44 % 44 % Expected term 6 years 6 years 6 years Risk-free interest rate 3.59 % 2.69 % 0.82 % Expected dividend yield — % — % — % Weighted-average grant date fair value per share $ 17.92 $ 33.99 $ 27.98 The expected volatility of options granted in 2023, 2022, and 2021 was determined using a weighted average of the historical volatility of our stock for a period equal to the expected life of the option. The expected life of options has been determined utilizing the “simplified” method. The risk-free interest rate is based on a zero-coupon U.S. treasury instrument whose term is consistent with the expected life of the stock options. The Company has not paid and do not anticipate paying cash dividends on our shares of common stock; therefore, the expected dividend yield is assumed to be zero . The Company applied an estimated annual forfeiture rate based on historical averages in determining the expense recorded in each period. A summary of the stock option activity under the Company’s stock option plans for the year ended December 31, 2023 is presented below: Options Weighted- Weighted- Aggregate Options outstanding at December 31, 2022 120,000 $ 37.29 Granted 25,000 36.46 Exercised ( 2,500 ) 7.03 $ 81 Forfeited — — Canceled ( 2,500 ) 7.03 Options outstanding at December 31, 2023 140,000 $ 38.22 6.34 $ 1,107 Options exercisable at December 31, 2023 115,000 $ 38.61 5.67 $ 1,107 Options vested or expected to vest at December 31, 2023 139,128 $ 38.24 6.32 $ 1,107 During the years ended December 31, 2023, 2022, and 2021, the total intrinsic value of options exercised (i.e. the difference between the market price of the underlying stock at exercise and the price paid by the employee to exercise the options) was $ 0.1 million , $ 1.1 million , and $ 0.2 million , respectively, and the total amount of cash received by the Company from exercise of these options was $ 17 thousand , $ 391 thousand , and $ 16 thousand , respectively. Restricted Stock Unit Awards Restricted stock unit awards are valued at the market price of a share of the Company’s common stock on the date of the grant. A summary of the restricted stock unit award activity under the Company’s plans for the year ended December 31, 2023 is presented below: Shares Weighted- Aggregate Nonvested outstanding at December 31, 2022 1,642,799 $ 62.40 Granted 799,263 33.63 Vested ( 841,714 ) 57.88 Forfeited ( 26,800 ) 61.36 Nonvested outstanding at December 31, 2023 1,573,548 $ 50.22 $ 54,853,883 The total grant-date fair value of restricted stock unit awards that vested during the years ended December 31, 2023, 2022, and 2021 was $ 48.7 million , $ 45.2 million , and $ 23.6 million , respectively. As of December 31, 2023, there was $ 60.7 million of total unrecognized compensation expense related to stock options and restricted stock units, which is expected to be recognized over a weighted average period of 1.90 years.

On June 7, 2022, 600,000 shares of the Company’s common stock were reserved for issuance under the ESPP. After the initial offering period of three months, commencing September 1, 2022, eligible employees will be offered shares of common stock over a twelve-month offering period, which consists of two consecutive six-month purchase periods. Employees may purchase a limited amount (up to $ 25,000 ) of shares of the Company’s common stock under the ESPP at a discount of up to 15 % of the lesser of the market value of the common stock at either (a) the beginning of the six-month purchase period during which the shares of common stock are purchased or (b) the end of such six-month purchase period. As of December 31, 2023, 545,556 shares of common stock remain available for issuance under the ESPP.

Income Taxes Income before provision for income taxes was as follows: Years Ended December 31, 2023 2022 2021 United States $ 14,380 $ 52,122 $ 5,804 Foreign 39 5,432 5,275 Income before income taxes $ 14,419 $ 57,554 $ 11,079 The income tax provision consisted of the following: Years Ended December 31, 2023 2022 2021 Current: Federal $ 6,733 $ 14,862 $ 5,587 State 2,525 3,830 1,407 Foreign 1,411 1,290 263 Total current 10,669 19,982 7,257 Deferred: Federal 1,126 ( 2,752 ) ( 867 ) State ( 442 ) ( 1,017 ) 313 Foreign ( 1,395 ) ( 268 ) 3,427 Total deferred ( 711 ) ( 4,037 ) 2,873 $ 9,958 $ 15,945 $ 10,130 The income tax provision for the years ended December 31, 2023, 2022 and 2021 differs from the amounts computed by applying the statutory federal income tax rate to consolidated income before provision for income taxes as follows: Years Ended December 31, 2023 2022 2021 Provision computed at statutory rate $ 3,028 $ 12,086 $ 2,327 Increase resulting from: Difference in rates for foreign jurisdictions 14 ( 42 ) ( 42 ) Stock-based compensation 5,050 ( 1,984 ) ( 3,903 ) Nondeductible inducement expense — — 4,458 Transaction-related fees 867 — — Other non-deductible expenses 167 131 97 Non-deductible officers compensation 1,639 4,098 1,665 State income tax provision 1,619 2,237 1,344 Subsidiary earnings taxed in the US ( 732 ) 333 1,176 Research and development credit ( 1,259 ) ( 726 ) ( 468 ) Valuation allowance ( 405 ) ( 343 ) 474 Change in tax rate ( 31 ) ( 24 ) 3,006 Other 1 179 ( 4 ) Provision for income taxes $ 9,958 $ 15,945 $ 10,130 Significant components of the Company’s net deferred tax assets and liabilities are as follows: As of December 31, 2023 2022 Deferred tax assets: Net operating loss carryforwards $ 3,146 $ 4,446 Right of use operating lease liability 5,251 6,178 Accruals and allowances 1,890 3,140 Stock-based compensation 4,879 4,553 Property and equipment 178 — Contract liabilities — 467 Other 130 4 Gross deferred tax assets 15,474 18,788 Less valuation allowance ( 836 ) ( 1,397 ) Total deferred tax assets 14,638 17,391 Deferred tax liabilities: Intangible asset ( 20,687 ) ( 21,642 ) Right of use operating lease asset ( 4,362 ) ( 5,179 ) Property and equipment — ( 915 ) Total deferred tax liabilities ( 25,049 ) ( 27,736 ) Net deferred tax liabilities $ ( 10,411 ) $ ( 10,345 ) As reported: Non-current deferred tax assets $ 2,445 $ 2,945 Non-current deferred tax liabilities $ ( 12,856 ) $ ( 13,290 ) In evaluating the ability to realize the net deferred tax asset, the Company considers all available evidence, both positive and negative, including past operating results, the existence of cumulative losses in the most recent fiscal years, tax planning strategies that are prudent and feasible, and forecasts of future taxable income. In considering sources of future taxable income, the Company makes certain assumptions and judgments which are based on the plans and estimates used to manage the underlying business of the Company. Changes in the Company’s assumptions and estimates, as well as changes in tax rates, may materially impact income tax expense for the period. The valuation allowances were $ 0.8 million and $ 1.4 million at December 31, 2023 and 2022 respectively. The valuation allowance is mainly against state NOL due to dilution of state apportionment. The Company had no unrecognized tax benefits at December 31, 2023. It is not expected that the amount of unrecognized tax benefits will change significantly within the next twelve months. The Company files income tax returns in the U.S. and in foreign jurisdictions. Generally, the Company is no longer subject to U.S., state, local and foreign income tax examinations by tax authorities in its major jurisdictions for years before 2017, except to the extent of NOL and tax credit carryforwards from those years. Major taxing jurisdictions include the U.S., both federal and state, and the United Kingdom. As of December 31, 2023 , the Company also had U.S. federal and state NOL carryforwards of $ 10.1 million, of which $ 3.7 million will begin to expire in 2036 and the remaining amount may be carried forward indefinitely. The Company also has foreign NOL carryforwards of $ 0.2 million, which may be carried forward indefinitely. The deferred tax assets related to the domestic NOL carryforwards have been partially offset by valuation allowance related to BrightTALK, Inc. and the deferred tax assets related to the foreign NOL carryforwards have been partially offset by a $ 0.1 million valuation allowance related to Hong Kong. The Company considers the excess of its financial reporting over its tax basis in investments in foreign subsidiaries essentially permanent in duration and as such has not recognized deferred tax liability related to this difference. Undistributed earnings of the Company’s foreign subsidiaries amounted to approximately $ 16.1 million as of December 31, 2023 . The Company has not provided any additional federal or state income taxes or foreign withholding taxes on the undistributed earnings as such earnings have been indefinitely reinvested in the business. Due to the various methods by which such earnings could be repatriated in the future, the amount of taxes attributable to the undistributed earnings is not practicably determinable.

Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenues, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals, the allocation of purchase price to intangibles and goodwill, and income taxes. Estimates of the carrying value of certain assets and liabilities are based on historical experience and on various other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates.
Revenue Recognition under ASC 606, Revenue from Contracts with Customers ("ASC 606")	Revenue Recognition under ASC 606, Revenue from Contracts with Customers (“ASC 606”) The Company generates its revenues from the sale of targeted marketing and advertising campaigns, which it delivers via its data analytic solutions. Revenue is recognized when performance obligations are satisfied by transferring promised goods or services to customers, as determined by applying a five-step process consisting of: a) identifying the contract, or contracts, with a customer, b) identifying the performance obligations in the contract, c) determining the transaction price, d) allocating the transaction price to the performance obligations in the contract, and e) recognizing revenue when, or as, performance obligations are satisfied. The Company’s offerings consist of: • IT Deal Alert™ . A suite of data, software and services for B2B technology companies that leverages the detailed purchase intent data we collect on enterprise technology organizations and professionals researching IT purchases via our network of websites and our webinar community platform. Through our proprietary data-capture and scoring methodologies, we use this insight to help our customers identify and prioritize accounts and contacts whose content consumption and online research activities around specific enterprise technology topics indicate they are “in-market” for a particular B2B technology product or service. The suite of products and services includes Priority Engine™ and Qualified Sales Opportunities™. Priority Engine™ is a subscription service powered by our Activity Intelligence™ platform, which integrates with customer relationship management (“CRM”) and marketing automation platforms (“MAPs”) including Salesforce.com, Marketo, Hubspot, Eloqua, Pardot, and Integrate. The service delivers lead generation workflow solutions designed to enable marketers and salesforces to identify and prioritize accounts and individuals actively researching new technology purchases or upgrades, and then to engage those active prospects. We launched IntentMail AI TM in December 2023, which is Priority Engine’s AI-powered messaging feature, which enables sellers to automatically generate personalized email copy. Qualified Sales Opportunities™ is a product that profiles specific in-progress purchase projects via surveys and interviews with business technology professionals whose research activity and content consumption is indicative of a pending technology purchase. Qualified Sales Opportunities™ include information on project scope, purchase criteria and vendors considered. • Demand Solutions. Our offerings enable our customers to reach and influence prospective buyers through content marketing programs, such as white papers, webcasts, podcasts, videocasts, virtual trade shows, and content sponsorships, designed to generate demand for their solutions, and through display advertising and other brand programs that influence consideration by prospective buyers. We believe this allows B2B technology companies to maximize ROI on marketing and sales expenditures by capturing sales leads from the distribution and promotion of content to our audience of enterprise technology and business professionals. • Brand Solutions . Our suite of brand solutions provide B2B technology companies with direct exposure to targeted audiences of enterprise technology and business professionals actively researching information related to their products and services. We leverage our Activity Intelligence™ platform to enable significant segmentation and behavioral targeting of audiences to improve the relevancy of digital ads to researcher needs. Branding solutions include on-network banner advertising and digital sponsorships, off-network banner targeting, and microsites and related formats. • Custom Content Creation. We deliver market insights and guidance to B2B technology companies through our Enterprise Strategy Group annual research and advisory subscription programs, custom market research services, and consulting engagements. In addition, Enterprise Strategy Group experts author custom content products including technical and economic validations, white papers, infographics, videos and webinars. This content is leveraged by B2B technology marketers to support product launches, enable demand-generation campaigns, and to establish overall thought leadership. We also create white papers, case studies, webcasts or videos to our customers’ specifications. These customized content assets are then promoted to our audience within both demand solutions and brand solutions programs. Additionally, we offer off-the-shelf editorial sponsorship products on topics aligned to customer markets, enabling them to engage and generate demand via packaged content created by our editorial staff to educate technology researchers on new technology trends and feature options. • BrightTALK platform. Allows our customers to create, host and promote webinars, virtual events and video content. Customers create their own hosted Channels on the platform where they schedule both live and on-demand webinars for promotion to BrightTALK’s community of in-market accounts and individuals. The BrightTALK Channel also enables customers to self-administer lead generation campaigns, set up workflow integrations between the Channel and their CRM and MAP systems, and access reporting detailing the size and growth of their community of subscribers over time. Customers may also create an off-network embedded Channel page on their own corporate website featuring content in their BrightTALK Channel, as well as an embedded BrightTALK registration form that captures and converts interested individuals to marketing leads. Revenue from demand and brand solutions is primarily recognized when the transfer of control occurs. Certain of the contracts within demand and brand solutions are duration-based campaigns which, in the event of customer cancellation, provide the Company with an enforceable right to a proportional payment for the portion of the campaign based on services provided. Accordingly, revenue from duration-based campaigns is recognized using a time-based measure of progress, which the Company believes best depicts how it satisfies its performance obligations in these arrangements as control is continuously transferred throughout the contract period. Revenue from custom content creation is recognized over the expected period of performance using a single measure of progress, typically based on hours incurred. Revenue from Priority Engine™ and the Bright TALK platform are recognized over a time-based measure of progress, which the Company believes best depicts how it satisfies its performance obligations in these arrangements as control is continuously transferred throughout the contract period. To determine standalone selling price for the individual performance obligations in the arrangement, the Company uses an estimate of the observable selling prices in separate transactions. The Company establishes best estimates considering multiple factors including, but not limited to, class of client, size of transaction, available inventory, pricing strategies and market conditions. The Company uses a range of amounts to estimate stand-alone selling price when it sells the goods and services separately and needs to determine whether a discount is to be allocated based upon the relative stand-alone selling price to the various goods and services. Judgment is required to determine the standalone selling price for each distinct performance obligation.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Financial instruments consist of cash, cash equivalents, short-term investments, accounts receivable, accounts payable, long-term debt and contingent consideration. Due to their short-term nature and liquidity, the carrying value of these instruments, with the exception of contingent consideration and long-term debt, approximates their estimated fair values. See Note 4 for further information on the fair value of the Company’s investments. The Company classifies all of its short-term investments as available-for-sale. The fair value of contingent consideration was estimated using a discounted cash flow method.
Business Combinations	Business Combinations The Company uses its best estimates and assumptions to assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. The Company’s estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions and tax-related valuation allowances are initially recorded in connection with a business combination as of the acquisition date. The Company continues to collect information and reevaluates these estimates and assumptions quarterly and records any adjustments to the Company’s preliminary estimates to goodwill provided that the Company is within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s consolidated statement of operations.
Long-Lived Assets, Goodwill and Indefinite-lived Intangible Assets	Long-Lived Assets , Goodwill and Indefinite-lived Intangible Assets Long-lived assets consist primarily of property and equipment, capitalized software, goodwill and other intangible assets. The Company reviews long-lived assets, including property and equipment and finite intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Conditions that would trigger an impairment assessment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of an asset or an adverse action or a significant decrease in the market price. A specifically identified intangible asset must be recorded as a separate asset from goodwill if either of the following two criteria is met: (1) the intangible asset acquired arises from contractual or other legal rights; or (2) the intangible asset is separable. Accordingly, intangible assets consist of specifically identified intangible assets. Goodwill is the excess of any purchase price over the estimated fair value of net tangible and intangible assets acquired. Goodwill and indefinite-lived intangible assets are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Separable intangible assets that are not deemed to have an indefinite life are amortized over their estimated useful lives, which range from eighteen months to nineteen years , using methods of amortization that are expected to reflect the estimated pattern of economic use, and are reviewed for impairment when events or changes in circumstances suggest that the assets may not be recoverable. Consistent with the Company’s determination that it has a single reporting segment, it has been determined that there is a single reporting unit and goodwill is therefore tested for impairment at the entity level. The Company performs its annual test of impairment of goodwill as of December 31st of each year and whenever events or changes in circumstances suggest that the carrying amount may not be recoverable using the two-step process required by ASC 350, Intangibles – Goodwill and Other (“ASC 350”). The first step of the impairment test is to identify potential impairment by comparing the reporting unit’s fair value with its net book value (or carrying amount), including goodwill. The fair value is estimated based on a market value approach. If the fair value of the reporting unit exceeds its carrying amount, the reporting unit’s goodwill is not considered to be impaired and the second step of the impairment test is not performed. Whenever indicators of impairment become present, the Company would perform the second step and compare the implied fair value of the reporting unit’s goodwill, as defined by ASC 350, to it carrying value to determine the amount of the impairment loss, if any. As of December 31, 2023, there were no indications of impairment based on the step one analysis, and the Company’s estimated fair value exceeded its goodwill carrying value by a significant margin. Based on the aforementioned evaluation, the Company believes that, as of the balance sheet date presented, none of the Company’s goodwill or other long-lived assets were impaired. The Company did no t have any intangible assets, other than goodwill, with indefinite lives as of December 31, 2023 or 2022 .
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The Company reduces gross trade accounts receivable for an allowance for doubtful accounts. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in its existing accounts receivable. The allowance for doubtful accounts is reviewed on a regular basis, and all past due balances are reviewed individually for collectability. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Provisions for doubtful accounts are recorded in general and administrative expense. Below is a summary of the changes in the Company’s allowance for doubtful accounts for the years ended December 31, 2023, 2022, and 2021. Balance at Provision Write-offs, Balance at Year ended December 31, 2023 $ 4,494 $ 2,021 $ ( 1,487 ) $ 5,028 Year ended December 31, 2022 $ 2,514 $ 2,239 $ ( 259 ) $ 4,494 Year ended December 31, 2021 $ 1,754 $ 904 $ ( 144 ) $ 2,514
Property and Equipment and Other Capitalized Assets	Property and Equipment and Other Capitalized Assets Property and equipment and other capitalized assets are stated at cost. Property and equipment acquired through acquisitions of businesses are initially recorded at fair value. Depreciation is calculated on the straight-line method based on the month the asset is placed in service over the following estimated useful lives: Estimated Useful Lives Furniture and fixtures 3 - 10 years Computer equipment and software 3 years Internal-use software and website development costs 3 - 5 years Leasehold improvements Shorter of useful life or remaining duration of lease Property and equipment and other capitalized assets consist of the following: As of December 31, 2023 2022 Furniture and fixtures $ 1,300 $ 1,361 Computer equipment and software 4,678 5,393 Leasehold improvements 3,786 3,867 Internal-use software and website development costs 70,233 56,340 79,997 66,961 Less: accumulated depreciation and amortization ( 55,080 ) ( 44,454 ) $ 24,917 $ 22,507 Depreciation expense was $ 12.4 million, $ 10.0 million, and $ 7.5 million for the years ended December 31, 2023, 2022, and 2021, respectively. Repairs and maintenance charges that do not increase the useful life of the assets are charged to operations as incurred. The Company wrote off approximately $ 1.9 million , $ 2.4 million , and $ 1.0 million of assets that were no longer in service during 2023, 2022, and 2021 , respectively. Depreciation expense is classified as a component of operating expense in the Company’s results of operations with the exception of certain depreciation expense which is classified as a component of cost of goods sold.
Internal-Use Software and Website Development Costs	Internal-Use Software and Website Development Costs The Company capitalizes costs incurred during the development of its website applications and infrastructure as well as certain costs relating to internal-use software. The Company begins to capitalize costs to develop software and website applications when planning stage 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. Judgment is required in determining the point at which various projects enter the state at which costs may be capitalized, in assessing the ongoing value of the capitalized costs and in determining the estimated useful lives over which the costs are amortized, which is generally three years. To the extent that the Company changes the manner in which it develops and tests new features and functionalities related to its websites, assesses the ongoing value of capitalized assets, or determines the estimated useful lives over which the costs are amortized, the amount of website development costs it capitalizes and amortizes in future periods would be impacted. The estimated useful lives of costs capitalized is evaluated for each specific project. Capitalized internal-use software and website development costs are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An impairment loss would be recognized only if the carrying amount of the asset is not recoverable and exceeds its fair value. The Company capitalized internal-use software and website development costs of $ 14.2 million , $ 12.9 million , and $ 11.5 million for the years ended December 31, 2023, 2022, and 2021 , respectively.
Debt Issuance Costs	Debt Issuance Costs Costs incurred with the issuance of the Company’s convertible debt are deferred and amortized as interest expense over the term of the related convertible instrument using the effective interest method. To the extent the convertible debt is outstanding, these amounts are reflected in the consolidated balance sheets as a deduction of the convertible debt.
Concentrations of Credit Risk and Off-Balance Sheet Risk	Concentrations of Credit Risk and Off-Balance Sheet Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist mainly of cash and cash equivalents, investments and accounts receivable. The Company maintains its cash and cash equivalents and investments principally in accredited financial institutions of high credit standing. The Company routinely assesses the credit worthiness of its customers. The Company generally has not experienced any significant losses related to individual customers or groups of customers in any particular industry or area. The Company does not require collateral. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company’s accounts receivable. At December 31, 2023, 2022 and 2021 , no customer represented 10% of total accounts receivable. No single customer accounted for 10% or more of total revenues in the years ended December 31, 2023, 2022, or 2021 .
Income Taxes	Income Taxes The Company’s deferred tax assets and liabilities are recognized based on temporary differences between the financial reporting and income tax bases of assets and liabilities using statutory rates. A valuation allowance is established against net deferred tax assets if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company records a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return using a “more likely than not” threshold as required by the provisions of ASC 740-10, Accounting for Uncertainty in Income Taxes (“ASC 740”). The Company recognizes interest and penalties related to unrecognized tax benefits, if any, in income tax expense.
Stock-Based Compensation	Stock-Based Compensation The Company has stock-based employee compensation plans which are more fully described in Note 11. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized in the Consolidated Statement of Income and Comprehensive Income using the straight-line method over the vesting period of the award. The Company uses the Black-Scholes option-pricing model to determine the fair value of stock option awards.
Comprehensive Income	Comprehensive Income Comprehensive income includes all changes in equity during a period, except those resulting from investments by stockholders and distributions to stockholders. The Company's comprehensive income includes changes in the fair value of the Company’s unrealized gains on available for sale securities and foreign currency translation adjustments. There were no reclassifications out of accumulated other comprehensive income in the periods ended December 31, 2023, 2022, or 2021 .
Foreign Currency	Foreign Currency The functional currency for each of the Company’s subsidiaries is the local currency of the country in which it is incorporated. All assets and liabilities are translated into U.S. dollar equivalents at the exchange rate in effect on the balance sheet date or at a historical rate. Revenues and expenses are translated at average exchange rates. Translation gains or losses are recorded in stockholders’ equity as an element of accumulated other comprehensive income (loss).
Net Income Per Share	Net Income Per Share Basic earnings per share is computed based on the weighted average number of common shares and vested restricted stock units outstanding during the period. Because the holders of unvested restricted stock units do not have non-forfeitable rights to dividends or dividend equivalents, the Company does not consider these restricted stock units to be participating securities that should be included in its computation of earnings per share under the two-class method. Diluted earnings per share is computed using the weighted average number of common shares and vested, undelivered restricted stock units outstanding during the period, plus the dilutive effect of potential future issuances of common stock relating to stock option and restricted stock unit programs using the treasury stock method. In calculating diluted earnings per share, the dilutive effect of stock options and restricted stock units is computed using the average market price for the respective period. In addition, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense of stock options and restricted stock units that are in-the-money. This results in the “assumed” buyback of additional shares, thereby reducing the dilutive impact of stock options and restricted stock units. A reconciliation of the numerator and denominator used in the calculation of basic and diluted net income per share is as follows: For the Years Ended December 31, 2023 2022 2021 Numerator: Net income $ 4,461 $ 41,609 $ 949 Denominator: Basic: Weighted average shares of common stock and vested, undelivered restricted stock units outstanding 28,327,591 29,589,000 28,434,213 Diluted: Weighted average shares of common stock and vested, undelivered restricted stock units outstanding 28,327,591 29,589,000 28,434,213 Effect of potentially dilutive shares 166,953 4,483,131 1,039,678 Total weighted average shares of common stock and vested, undelivered restricted stock units outstanding and potentially dilutive shares 28,494,544 34,072,131 29,473,891 Calculation of Net Income Per Common Share: Basic: Net income applicable to common stockholders $ 4,461 $ 41,609 $ 949 Weighted average shares of stock outstanding 28,327,591 29,589,000 28,434,213 Net income per common share $ 0.16 $ 1.41 $ 0.03 Diluted: Net income applicable to common stockholders(1) $ 4,461 $ 44,173 $ 949 Weighted average shares of stock outstanding 28,494,544 34,072,131 29,473,891 Net income per common share(2) $ 0.16 $ 1.30 $ 0.03 (1) For the year ended December 31, 2022, we excluded $ 2.6 million of amortization and interest expense relating to our convertible notes when calculating net income for diluted earnings per share. There was no such adjustment in 2023 or 2021, due to anti-dilutive nature of the add-back. (2) In calculating diluted net income per share, 1.3 million shares, 107 thousand shares, and 14 thousand shares related to outstanding stock options and unvested, undelivered restricted stock units which were excluded for the years ended December 31, 2023, 2022, and 2021 , respectively, because they were anti-dilutive. Additionally, in calculating diluted net income per share, weighted average shares includes 3.9 million shares related to the if converted basis of our convertible notes for the year ended December 31, 2022. There was no such adjustment for 2023 or 2021 due to the anti-dilutive nature of the add-back.

All level 2 investments are priced using observable inputs, such as quoted prices in markets that are not active and yield curves. (2) Contingent consideration liabilities are measured using the income approach and discounted to present value based on an assessment of the probability that the Company would be required to make such future payments. The contingent consideration liabilities are measured at fair value using significant Level 3 (unobservable) inputs, such as discount rates and probability measures. Remeasurement of the contingent consideration to fair value is expensed through the income statement in the period remeasured. In 2022, we recorded a decrease in amortization expense of $ 0.5 million related to the revaluation of contingent consideration. In 2021, we recorded amortization expense of $ 3.7 million related to the revaluation of contingent consideration. Contingent consideration–current is included in accrued expenses and other current liabilities on the balance sheet.

There was no such adjustment in 2023 or 2021, due to anti-dilutive nature of the add-back. In calculating diluted net income per share, 1.3 million shares, 107 thousand shares, and 14 thousand shares related to outstanding stock options and unvested, undelivered restricted stock units which were excluded for the years ended December 31, 2023, 2022, and 2021 , respectively, because they were anti-dilutive. Additionally, in calculating diluted net income per share, weighted average shares includes 3.9 million shares related to the if converted basis of our convertible notes for the year ended December 31, 2022. There was no such adjustment for 2023 or 2021 due to the anti-dilutive nature of the add-back.

[1] The Company's time deposits consist of domestic deposits which mature within nine months (Level 2). All level 2 investments are priced using observable inputs, such as quoted prices in markets that are not active and yield curves. Contingent consideration liabilities are measured using the income approach and discounted to present value based on an assessment of the probability that the Company would be required to make such future payments. The contingent consideration liabilities are measured at fair value using significant Level 3 (unobservable) inputs, such as discount rates and probability measures. Remeasurement of the contingent consideration to fair value is expensed through the income statement in the period remeasured. In 2022, we recorded a decrease in amortization expense of $ 0.5 million related to the revaluation of contingent consideration. In 2021, we recorded amortization expense of $ 3.7 million related to the revaluation of contingent consideration. Contingent consideration–current is included in accrued expenses and other current liabilities on the balance sheet.
