SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements about us and our industry that involve substantial risks and uncertainties. All statements other than statements of historical facts contained in this Quarterly Report on Form 10-Q, including statements regarding our future results of operations, financial condition, business strategy, plans and objectives of management for future operations, our market opportunity and the potential growth of that market, our liquidity and capital needs and other similar matters, are forward-looking statements. In some cases, you can identify forward-looking statements because they contain words such as “anticipate,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “will,” or “would,” or the negative of these words or other similar terms or expressions. These forward-looking statements are based on management’s current expectations and assumptions about future events, which are inherently subject to uncertainties, risks, and changes in circumstances that are difficult to predict. Forward-looking statements contained in this Quarterly Report on Form 10-Q include, but are not limited to, statements concerning the following:

•    our future financial performance, including our revenue, annual recurring revenue (“ARR”), dollar-based net revenue retention rate, costs of revenue, gross profit or gross margin and operating expenses;

•    the sufficiency of our cash and cash equivalents to meet our liquidity needs;

•    anticipated trends and growth rates in our business and in the markets in which we operate;

•    our ability to maintain the security and availability of our internal networks and platform;

•    our ability to attract new paying customers and convert free customers into paying customers;

•    our ability to retain and expand sales to our existing paying customers, including upgrades to premium subscriptions and purchases of add-on offerings;

•    our ability to access, collect, and analyze data;

•    our ability to successfully expand in our existing markets and into new markets;

•    our ability to effectively manage our growth and future expenses;

•    our ability to continue to innovate and develop new products and features, improve our data assets, and enhance our technological capabilities;

•    our ability to maintain, protect, and enhance our intellectual property;

•    our ability to build, maintain, and enhance our brand, including through informational resources, advertisements, and referrals;

•    our ability to comply with modified or new laws and regulations applying to our business, including in any new jurisdictions in which we operate;

•    the attraction and retention of qualified employees and key personnel;

•    our anticipated investments in sales and marketing, and research and development;

•    our ability to successfully defend litigation brought against us;

•    our expectations regarding identifying, evaluating, executing, and integrating strategic acquisitions; and

•    the impact of global financial, economic, and political events on our business, industry and supply chain, including health epidemics, rising inflation, fluctuating interest rates, and market uncertainty and volatility.

You should not rely upon forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this Quarterly Report on Form 10-Q primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition, results of operations and prospects. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties and other factors described in the section titled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2023 and elsewhere in this Quarterly Report on Form 10-Q. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this Quarterly Report on Form 10-Q. The results, events and circumstances reflected in the forward-looking statements may not be achieved or occur, and actual results, events, or circumstances could differ materially from those described in the forward-looking statements.

The forward-looking statements made in this Quarterly Report on Form 10-Q relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made in this Quarterly Report on Form 10-Q to reflect events or circumstances after the date of this Quarterly Report on Form 10-Q or to reflect new information or the occurrence of unanticipated events, except as required by law. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures, or investments we may make.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. Unless stated otherwise, these statements are based upon information available to us as of the date of this Quarterly Report on Form 10-Q. While we believe such information provides a reasonable basis for such statements, such information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and you are cautioned not to unduly rely upon these statements.

Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

The unaudited condensed consolidated interim financial statements have been prepared on the same basis as the audited annual consolidated financial statements as of and for the year ended December 31, 2023, and, in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of June 30, 2024, and for the three and six months ended June 30, 2024 and 2023. The consolidated balance sheet as of December 31, 2023 included herein was derived from the audited consolidated financial statements as of that date.

The results for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024, any other interim periods, or any future year or period.

The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 7, 2024.

The accompanying unaudited condensed consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to the unaudited condensed consolidated financial statements. As of June 30, 2024, there have been no material changes in the Company's significant accounting policies from those that were disclosed in the Annual Report on Form 10-K, except as discussed below.

2.Summary of Significant Accounting Policies

Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, and subsidiaries in which it holds a controlling interest. All intercompany transactions and balances have been eliminated in consolidation. Ownership interests in subsidiaries represented by other parties that do not control the entity are presented in the consolidated financial statements as activities and balances attributable to noncontrolling interests.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Significant estimates relied upon in preparing these unaudited condensed consolidated financial statements include, but are not limited to, revenue recognition, expected future cash flows used to evaluate the recoverability of long-lived assets, contingent liabilities, expensing and capitalization of research and development costs for internal-use software, the average period of benefit associated with costs capitalized to obtain revenue contracts, the determination of the fair value of stock-based awards issued, stock-based compensation expense, the determination of the estimated fair value of loan receivables and convertible notes held by the Company, the valuations of the intangible assets acquired through acquisitions, the estimation of the Company’s incremental borrowing rate, and the recoverability of the Company’s net deferred tax assets and related valuation allowance.

Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made.

Subsequent Events Considerations

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the unaudited condensed consolidated financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. See Note 18 for additional information regarding the Company’s subsequent events.

Emerging Growth Company Status

The Company is an "emerging growth company" (“EGC”), as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”). Based on the market value of our common equity held by non-affiliates as of June 28, 2024 (the last business day of our most recently completed second fiscal quarter), we will cease to qualify as an emerging growth company as of the end of the fiscal year ending December 31, 2024. As a result, beginning with our Annual Report on Form 10-K for the year ending December 31, 2024, we will be subject to certain requirements that apply to other public companies but did not previously apply to us due to our status as an emerging growth company, including the provisions of Section 404 of the Sarbanes-Oxley Act, which require that our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting.

Revenue Recognition

The Company primarily derives revenue from subscriptions to the Company’s SaaS services and related customer support. For the three and six months ended June 30, 2024 and 2023, subscription revenue accounted for nearly all of the Company’s revenue. Revenue related to other revenue was not material for the three and six months ended June 30, 2024 and 2023.

The Company offers subscriptions to its platform primarily on a monthly or annual basis. The Company sells its products and services primarily through a self-service model and also directly through its sales force. The Company’s subscription arrangements provide customers the right to access the Company’s hosted software applications. Customers do not have the right to take possession of the Company’s software during the hosting arrangement. Subscriptions are generally non-cancellable during the contractual subscription term; however, subscription contracts contain a right to a refund if requested within seven days of purchase.

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration it expects to receive in exchange for those products or services. There were no changes to the Company’s revenue recognition policies since the filing of its Annual Report on Form 10-K with the SEC on March 7, 2024.

Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. The Company primarily invoices and collects payments from customers for its services in advance on a monthly or annual basis.

Deferred revenue represents amounts billed for which revenue has not yet been recognized. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as deferred revenue, and the remaining portion is recorded as deferred revenue, net of current portion. Deferred revenue increased by $8,185 as of June 30, 2024 compared to December 31, 2023. During the three and six months ended June 30, 2024, $32,354 and $39,426 of revenue was recognized that was included in deferred revenue at the beginning of each respective period. During the three and six months ended June 30, 2023, $27,865 and $37,831 of revenue was recognized that was included in deferred revenue at the beginning of each respective period.

The Company has elected to exclude amounts charged to customers for sales tax from the transaction price. Accordingly, revenue is presented net of any sales tax collected from customers.

Transaction Price Allocated to Future Performance Obligations

ASC 606 requires that the Company disclose the aggregate amount of the transaction price that is allocated to performance obligations that have not yet been satisfied as of the balance sheet dates reported.

8

For contracts with an original expected duration greater than one year, the aggregate amount of the transaction price allocated to the performance obligations that were unsatisfied as of June 30, 2024 was $1,207, of which the Company expects to recognize $970 over the next 12 months.

For contracts with an original expected duration of one year or less, the Company has applied the practical expedient available under ASC 606 to not disclose the amount of transaction price allocated to unsatisfied performance obligations as of June 30, 2024. For performance obligations not satisfied as of June 30, 2024, and to which this expedient applies, the nature of the performance obligations is consistent with performance obligations satisfied as of December 31, 2023.

Costs to Obtain a Contract

The incremental direct costs of obtaining a contract, which primarily consist of sales commissions paid for new subscription contracts, are deferred and recorded as deferred contract costs in the unaudited condensed consolidated balance sheets and are amortized over a period of approximately 24 months on a systematic basis, consistent with the pattern of transfer of the goods or services to which the asset relates. The 24-month period represents the estimated benefit period of the customer relationship and has been determined by taking into consideration the type of product sold, the commitment term of the customer contract, the nature of the Company’s technology development life-cycle, and an estimated customer relationship period based on historical experience and future expectations. Deferred contract costs that will be recorded as expense during the succeeding 12-month period are recorded as deferred contract costs, current portion, and the remaining portion is recorded as deferred contract costs, net of current portion. Amortization of deferred contract costs is included in sales and marketing expense in the accompanying unaudited condensed consolidated statements of operations and comprehensive income (loss).

Concentrations of Credit Risk and Significant Customers

The Company has no off-balance sheet risk, such as foreign exchange contracts, option contracts, or other hedging arrangements. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. 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.

Credit risk with respect to accounts receivable is dispersed due to the large number of customers of the Company. The Company routinely assesses the creditworthiness of its customers and generally does not require its customers to provide collateral or other security to support accounts receivable. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. 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.

As of June 30, 2024 and December 31, 2023, no individual customer represented more than 10% of the Company’s accounts receivable. During the three and six months ended June 30, 2024 and 2023, no individual customer represented more than 10% of the Company’s revenue.

Disclosure of Fair Value of Financial Instruments

The Company’s financial instruments include cash, cash equivalents, investments, accounts receivable, loan receivables, accounts payable, and accrued expenses. The Company’s investments are classified as available-for-sale and reported at fair value in accordance with the market approach utilizing quoted prices that were directly or indirectly observable. The Company has elected the fair value option in respect to the accounting for its loan receivable investment, resulting in increases and decreases in the fair value of such investments being recorded to other income, net for each reporting period. The carrying

9

amount of the remainder of the Company’s financial instruments approximated their fair values as of June 30, 2024 and December 31, 2023, due to the short-term nature of these instruments.

The Company has evaluated the estimated fair value of financial instruments using available market information. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts. See below for further discussion.

Foreign Currency Translation

The Company operates in a multi-currency environment having transactions in such currencies as the U.S. dollar, zloty, Czech koruna, euro, and others. The reporting currency of the Company is the U.S. dollar.

The foreign currency exchange gain (loss) included in other income, net for the three months ended June 30, 2024 and 2023 was $128 and $0, respectively. The foreign currency exchange gain (loss) included in other income, net for the six months ended June 30, 2024 and 2023 was $573 and $(638), respectively.

Comprehensive income (loss)

Comprehensive income (loss) is comprised of two components: net income (loss) and other comprehensive income (loss), which includes other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. For the three and six months ended June 30, 2024 and 2023, comprehensive income (loss) consists of net income (loss), the change in the cumulative foreign currency translation adjustment, and unrealized loss on investments. The tax effect of the cumulative foreign currency translation adjustment and unrealized loss on investments was not significant for the three and six months ended June 30, 2024 and 2023.

Recent Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. 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 evaluating the impact of adopting ASU 2023-07 on its consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740)-Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires that an entity disclose specific categories in the effective tax rate reconciliation as well as provide additional information for reconciling items that meet a quantitative threshold. Further, ASU 2023-09 requires certain disclosures of state versus federal income tax expense and taxes paid. The amendments in ASU 2023-09 are required to be adopted for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied on a prospective basis although retrospective application is permitted. The Company is evaluating the impact of adopting ASU 2023-09 on its consolidated financial statements and disclosures.

3.    Cash, Cash Equivalents, Restricted Cash, and Investments

The Company considers all highly liquid instruments purchased with an original maturity date of 90 days or less from the date of purchase to be cash equivalents. Cash and cash equivalents consist of cash

10

on deposit with banks and amounts held in interest-bearing money market funds. Cash equivalents are carried at cost, which approximates their fair market value. Short‑term investments consist of investments with original maturities greater than 90 days, as of the date of purchase. The Company considers its investment portfolio available-for-sale. The Company adjusts the cost of investments for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion in interest income in the unaudited condensed consolidated statements of operations.

When the Company holds debt investments classified as available-for-sale pursuant to ASC 320, Investments — Debt Securities, it records available-for-sale securities at fair value, with unrealized gains and losses included in accumulated other comprehensive loss in stockholders’ equity. The Company has classified its investments with maturities beyond one year as short term, based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. The Company includes interest and dividends on securities classified as available-for-sale in interest income in the unaudited condensed consolidated statements of operations and comprehensive income (loss). Realized gains and losses are recorded in the unaudited condensed consolidated statements of operations and comprehensive income (loss) based on the specific-identification method. There was no material realized gains or losses on investments for the three and six months ended June 30, 2024 or 2023. As of June 30, 2024 and December 31, 2023, the aggregate fair value of investments held by the Company in an unrealized loss position for less than twelve months was $88,741 and $89,381, respectively. As of June 30, 2024, the aggregate fair value of investments held by the Company in a continuous unrealized loss position for greater than twelve months was $55,382. The Company did not hold any investments in an unrealized loss position for greater than twelve months as of December 31, 2023.

On January 1, 2023, the Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) and ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815 Derivatives and Hedging and Topic 825, Financial Instruments. Under these standards, the Company reviews available-for-sale securities for impairment whenever the fair value of the security is less than its amortized cost. If impairment exists and the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis, the Company will write down the amortized cost basis to its fair value at the reporting date, recognizing the difference as a loss within other income, net in the unaudited condensed consolidated statements of operations. If the Company does not intend to sell the security nor is it more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis, the Company will determine if any portion of the unrealized loss on the security is due to credit loss. If the impairment is entirely or partially due to credit loss, the Company will measure the credit loss up to the amount of the difference between fair value and amortized cost, and recognize an allowance for credit losses along with the related charge against earnings as a loss within other income, net in the unaudited condensed consolidated statements of operations. The remaining impairment amount due to all other factors is recognized in accumulated other comprehensive income (loss) in the unaudited condensed consolidated balance sheets. Subsequent changes to the Company’s estimate of credit losses will be recorded as adjustments to the allowance for credit losses and other income, net. For the three and six months ended June 30, 2024, the Company determined that no impairments were required to be recognized in the unaudited condensed consolidated statements of operations.

The following is a summary of cash, cash equivalents, and investments as of June 30, 2024 and December 31, 2023:

	Amortized  Cost		Gross Unrealized Gains		Gross Unrealized Losses		Estimated Fair Value
June 30, 2024
Cash and cash equivalents	$	69,636	$	—	$	(10)	$	69,626

Cash and cash equivalents	$	58,848	$	—	$	—	$	58,848
Investments:
U.S. treasury securities due in one year or less	179,843		265		(387)		179,721
Total investments	179,843		265		(387)		179,721
Total cash, cash equivalents and investments	$	238,691	$	265	$	(387)	$	238,569

The Company considered the extent to which any unrealized losses on its marketable securities were driven by credit risk and other factors, including market risk, and if it is more-likely-than-not that the Company would have to sell the security before the recovery of the amortized cost basis. As of June 30, 2024 and December 31, 2023, the unrealized losses related to its marketable securities were due to rising market interest rates compared to when the investments were initiated. The Company does not believe the unrealized losses represent credit risk, and the Company does not intend to sell any of the securities in an unrealized loss position and it is not likely that the Company would be required to sell these securities before recovery of their amortized cost basis, which may be at maturity. Thus, no credit loss was recognized for the Company's marketable securities for the three and six months ended June 30, 2024 and 2023.

As of June 30, 2024, the Company held $40,203 in U.S. treasury securities with maturities within one year and $121,703 in U.S. treasury securities with maturities after one year and within three years.

Restricted Cash

As of June 30, 2024, restricted cash totaled $11,903 and included $11,718 related to the Company’s Brand 24 tender offer (See Note 9) and $185 related to cash held as collateral for a letter of credit related to the contractual provisions for one of the Company’s office leases.

5.    Fair Value Measurement

The following tables summarize financial assets and liabilities measured and recorded at fair value on a recurring basis in the accompanying consolidated balance sheets as of June 30, 2024 and December 31, 2023, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

	June 30, 2024
	Quoted Prices in Active Markets for Identical Assets (Level 1 Inputs)		Significant Other Observable Inputs (Level 2 Inputs)		Significant Unobservable Inputs (Level 3 Inputs)		Total
Assets:
Money market funds	$	19,272	$	—	$	—	$	19,272
U.S. treasury securities	—		161,906		—		161,906

Liabilities:
Contingent consideration	$	—	$	—	$	751	$	751
Total liabilities	$	—	$	—	$	751	$	751

	December 31, 2023
	Quoted Prices in Active Markets for Identical Assets (Level 1 Inputs)		Significant Other Observable Inputs (Level 2 Inputs)		Significant Unobservable Inputs (Level 3 Inputs)		Total
Assets:
Money market funds	$	54,269	$	—	$	—	$	54,269
U.S. treasury securities	—		179,721		—		179,721
Total assets	$	54,269	$	179,721	$	—	$	233,990
Liabilities:
Contingent consideration	$	—	$	—	$	597	$	597
Total liabilities	$	—	$	—	$	597	$	597

Cash equivalents include money market funds with original maturities of 90 days or less from the date of purchase. The fair value measurement of these assets is based on quoted market prices in active markets for identical assets and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 1 in the fair value hierarchy. The Company’s investments primarily consist of U.S. treasury securities. The fair value measurement of these assets is based on significant other observable inputs and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 2 in the fair value hierarchy.

As of June 30, 2024, the Company measured its investment loan receivables (see Note 7) and its contingent consideration associated with the acquisition of Datos Inc. on a recurring basis using significant unobservable inputs (Level 3). As of December 31, 2023, the Company measured its contingent consideration associated with the acquisition of Datos Inc. on a recurring basis using significant unobservable inputs (Level 3).

15

Contingent consideration

The Company records contingent consideration resulting from a business combination at its fair value on the acquisition date. The Company generally determines the fair value of the contingent consideration using the Monte Carlo simulation model. Each reporting period thereafter, these obligations are revalued and increases or decreases in their fair values are recorded as an adjustment to other income, net within the unaudited condensed consolidated statements of operations and comprehensive income (loss). Changes in the fair value of the contingent consideration can result from changes in assumed discount periods and rates, and from changes pertaining to the estimated or actual achievement of the defined milestones. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period. Accordingly, future business and economic conditions, as well as changes in any of the assumptions described above, can materially impact the amount of contingent consideration expense the Company records in any given period.

The total estimated fair value of the contingent consideration payable was $751 and $597 as of June 30, 2024 and December 31, 2023, respectively. The following table represents the key inputs used in the fair value calculations:

	June 30, 2024		December 31, 2023
Risk free interest rate	5.00	%	4.80	%
Projected year of payment	2025		2025
Revenue volatility	10.0	%	11.0	%
Discount rate	7.60	%	7.70	%

Changes in the estimated fair value of the Datos contingent consideration payable will be recognized in other income, net. A rollforward of the fair value measurements of the contingent consideration liability for the six months ended June 30, 2024 is as follows:

Balance as of December 31, 2023	$	597
Change in fair value and expense recognized for service period rendered	21
Balance as of March 31, 2024	618
Change in fair value and expense recognized for service period rendered	133
Balance as of June 30, 2024	751

6.    Property and Equipment, Net

Property and equipment consists of the following:

	As of
	June 30, 2024		December 31, 2023
Computer equipment	$	13,060	$	11,084
Furniture and office equipment	1,947		1,965
Leasehold improvements	2,803		2,469
Total property and equipment	17,810		15,518
Less: accumulated depreciation and amortization	(10,415)		(8,832)
Property and equipment, net	$	7,395	$	6,686

Depreciation and amortization expense related to property and equipment was $744 and $1,783 for the three and six months ended June 30, 2024, respectively. Depreciation and amortization expense related to property and equipment was $957 and $1,795 for the three and six months ended June 30, 2023, respectively.

7.    Other Assets

Investment Loan Receivable

In March 2024, the Company entered into a loan agreement in which it has loaned $7,000 to the borrower with a repayment date in March 2025. In addition to the loan facility, the Company entered into an option agreement with the borrower in which the Company has the right, but not the obligation, to acquire a majority of the outstanding common stock of the borrower during the period beginning July 1, 2024 and ending August 31, 2024. The Company accounts for the loan agreement and option agreement as a single financial instrument (together, the “Investment Loan Receivable”). The Company recorded the Investment Loan Receivable at its fair value of $7,000 on the agreement date. As of June 30, 2024, the fair value of the Investment Loan Receivable was $7,083 and was included in prepaid expenses and other current assets in the unaudited condensed consolidated balance sheet.

With respect to its investment loan receivable, the Company held a variable interest in the borrower, which is a variable interest entity. After evaluation of the relationship between the Company and this variable interest entity, the Company determined not to consolidate this variable interest entity’s results of operations for the three and six months ended June 30, 2024. Significant judgments included the determination that the Company was not the primary beneficiary of the variable interest entity given the Company’s variable interests did not constitute a controlling financial interest.

The Company elected to account for this investment by utilizing the fair value option. The Company records investment loan receivables at their fair value on the agreement date. Each reporting period thereafter, these receivables are revalued and increases or decreases in their fair values are recorded as an adjustment to other income, net within the unaudited condensed consolidated statements of operations and comprehensive income (loss). The Company generally determines the fair value using the discounted cash flow method. The significant assumptions used to estimate the fair value include the interest rate, risk-free rate, expected repayment date, equity value, equity volatility, expected timing of exercise, and the credit spread assumption specific to the investment loan. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period.

8.    Net Income (Loss) Per Share

For the three and six months ended June 30, 2024, diluted net income per share was calculated by dividing net income attributable to Semrush Holdings, Inc. by the weighted-average number of shares of common stock outstanding during the period, including the dilutive impact of stock options and shares of common stock issuable upon the vesting of Restricted Stock Units (“RSUs”). The adjustment to net income attributable to Semrush Holdings, Inc. related to the Company’s redeemable noncontrolling interest is not material and did not impact net income per share for the three and six months ended June 30, 2024.

For the three and six months ended June 30, 2023, the net loss attributable to common stockholders is divided by the weighted-average number of shares of common stock outstanding during the period to calculate both basic and diluted earnings per share. The dilutive effect of common stock equivalents has been excluded from the calculation of diluted net loss per share for these periods as its effect would have been anti-dilutive due to the net losses incurred for the periods.

The following table presents a reconciliation of weighted-average shares outstanding used in the calculation of basic and diluted net income (loss) per share:

	Three Months Ended June 30,		Six Months Ended June 30,
	2024	2023	2024	2023
Weighted-average shares outstanding:
Weighted-average number of shares of common stock used in computing net income (loss) per share attributable to common stockholders—basic	145,678,323	142,239,140	145,121,951	141,946,425
Dilutive effect of share equivalents resulting from stock options	1,940,654	—	2,066,972	—
Dilutive effect of share equivalents resulting from restricted stock units	1,206,334	—	1,072,484	—
Weighted-average number of shares of common stock used in computing net income (loss) per share attributable to common stockholders—diluted	148,825,311	142,239,140	148,261,407	141,946,425

The following potentially dilutive common stock equivalents, including stock options and restricted stock units, have been excluded from the calculation of diluted weighted-average shares outstanding for the three and six months ended June 30, 2024 and 2023 because to do so would have been anti-dilutive for the periods presented:

	Three Months Ended June 30,		Six Months Ended June 30,
	2024	2023	2024	2023
Stock options outstanding	2,321,962	8,619,112	3,445,481	8,619,112
Unvested RSUs	930,049	2,783,782	1,442,837	2,783,782
	3,252,011	11,402,894	4,888,318	11,402,894

For the three and six months ended June 30, 2024, 1,128,021 and 1,128,021 shares of Class A common stock potentially issuable under Performance Stock Unit (“PSU”) awards were excluded from the table above, respectively. For the three and six months ended June 30, 2023, 1,077,726 shares of Class A common stock potentially issuable under PSU awards were excluded from the table above, respectively. The performance-based conditions had not been met and were deemed improbable of achievement as of the reporting period end date. See Note 14 for additional information regarding the Company’s PSU awards.

9.    Acquisitions, Intangible Assets, and Goodwill

Acquisitions

Brand 24

On April 29, 2024, the Company completed a stock purchase agreement to acquire approximately 58% of the voting equity interests in Brand 24 S.A. (“Brand 24”). The Company has accounted for this transaction as a business combination under the acquisition method. The purpose of the business combination was to expand our public relations business and customer base. The acquisition date fair value of the consideration transferred consisted of the following:

	Acquisition Date
Consideration transferred	Fair Value
Cash paid at close	$	10,650
Fair value of deferred purchase payments	2,878
Consideration transferred	$	13,528
Redeemable noncontrolling interest	9,846
Total purchase consideration	$	23,374

The Company determined that the fair value of the assets acquired and liabilities assumed was $23,374, including the fair value of the redeemable noncontrolling interest in Brand 24 of $9,846, which is reflected outside of the stockholders’ equity section of the unaudited condensed consolidated balance sheet as of June 30, 2024. The fair value of the redeemable noncontrolling interest on the closing date was estimated considering the implied enterprise value and the acquired percentage of Brand 24. The fair value of deferred purchase payments represents the fair value of two payments of $1,500 each, the first of which will be paid December 31, 2024 and is included within other current liabilities within the unaudited condensed consolidated balance sheet as of June 30, 2024. The second payment is due November 12, 2025 and is included in other long term liabilities within the unaudited condensed consolidated balance sheet as of June 30, 2024. The deferred purchase payments will accrue interest of 2.5% per year.

19

The table below summarizes the Company’s preliminary purchase price allocation. The allocation of the purchase price is preliminary as of June 30, 2024 as the Company continues to gather information supporting the acquired assets and liabilities to finalize the purchase price allocation.

	Purchase Price
Assets acquired	Allocation
Fair value of tangible assets:
Cash and cash equivalents	$	1,502
Accounts Receivable	139
Other assets	686
Identifiable intangible assets	9,350
Goodwill	15,846
Total assets acquired	$	27,523
Liabilities assumed
Deferred revenue, current	847
Deferred tax liabilities	1,411
Other liabilities	1,891
Total Liabilities Assumed	$	4,149
Fair value of assets acquired and liabilities assumed, net	$	23,374
Fair value of redeemable noncontrolling interest	$	9,846
Fair value of controlling interest acquired	$	13,528

The Company allocated $9,350 of the purchase price to identifiable intangible assets consisting of customer relationships, developed technology, and trade names, which it amortizes over the assets’ useful lives using a straight-line amortization method. The Company assigned useful lives to acquired customer relationships, developed technology, and trade names, of six years, five years, and five years, respectively. The Company used the multi-period excess earnings method to value the customer relationships. Customer relationships represent the underlying relationships with certain customers to provide ongoing services for products sold. To value the developed technology and trade names assets, the Company utilized the relief from royalty method. Trade names primarily relate to the Brand 24 brand. The significant assumptions used to estimate the value of the intangible assets included the discount rate, revenue growth rates, and customer attrition rates. After allocating the purchase price to identifiable assets acquired and liabilities assumed, the remaining purchase price was allocated to goodwill, which primarily relates to expected synergies from combining operations and is not deductible for tax purposes.

The Company recorded $225 and $389 in transaction costs related to the transaction during the three and six months ended June 30, 2024, respectively, which are included in the unaudited condensed consolidated statements of operations and comprehensive income (loss) in its income from continuing operations under the line item, General and administrative.

As of April 29, 2024, the results of Brand 24’s operations are included within the Company’s consolidated financial statements. This business combination did not have a material impact on the Company’s consolidated financial statements. Therefore, actual results of operations subsequent to the acquisition date and pro forma results of operations have not been presented.

In April 2024 the Company entered into award agreements with certain members of Brand 24 Management. These awards are accounted for as liability-classified awards under ASC 718, Compensation - Stock Compensation. The fair value of the awards were estimated using a Monte Carlo Simulation. The Company recorded $150 in post-acquisition compensation expense related to these awards during the three and six months ended June 30, 2024.

In May 2024, the Company announced a tender offer to purchase up to 944,616 shares of Brand 24 (the “Tender Offer”) at a price equal to PLN47.0 per share with an opening date for subscriptions of May

20

31, 2024 and a closing date for subscriptions of July 2, 2024. The Tender Offer was mandatory due to Polish Law and as a result has been accounted for as redeemable noncontrolling interest classified in temporary equity in the unaudited condensed consolidated balance sheet as of June 30, 2024. As a result of the Tender Offer, the fair value of the redeemable noncontrolling interest was adjusted to the redemption value equal to the Tender Offer price. The $978 difference between the acquisition date fair value of the redeemable noncontrolling interest and the Tender Offer price was recorded through additional paid-in capital in the unaudited condensed consolidated balance sheet as of June 30, 2024.

As of June 30, 2024, the Company received notice for the sale of 177,474 shares resulting in the reclassification of $2,021 in Tender Offer obligations from redeemable noncontrolling interest to other current liabilities.

Datos

On December 1, 2023, the Company completed a stock purchase agreement to acquire approximately 60% of the voting equity interests in Datos Inc. (“Datos”). The Company has accounted for this transaction as a business combination under the acquisition method. The primary purpose of this business combination is to acquire Datos’ valuable clickstream data software. The Company performed acquisition accounting as of December 1, 2023. The acquisition date fair value of the consideration transferred consisted of the following:

	Acquisition Date
Consideration transferred	Fair Value
Fair value of the January 2021 and February 2022 Convertible Notes	$	7,530
Cash paid at close	4,255
Other consideration	2,070
Total purchase consideration	$	13,855

The Company determined that the fair value of the assets acquired and liabilities assumed was $19,021, including the fair value of the noncontrolling interest in Datos of $5,166. The fair value of the noncontrolling interest is inclusive of the fair value of the acquired call option, which gives the Company the right, but not the obligation, to purchase the remaining shares in Datos during the period beginning January 1, 2026 and ending on January 1, 2027 (the “Call Option”). The Company estimated the fair value of the noncontrolling interest, inclusive of the Call Option, using an option pricing method (a special case of the income approach), considering the initial transaction price and based on Level 3 significant unobservable inputs such as the total equity value of Datos, forecasted revenues, volatility, and risk-adjusted discount rates. Other consideration includes the deferred purchase payments, the contingent payment, and additional consideration due to the seller. A payment of $501 was made during March 2024 related to other consideration. The remaining fair value of other consideration has been recorded to other current liabilities in the unaudited condensed consolidated balance sheet as of June 30, 2024.

21

The Company recorded $0 and $100 in transaction costs related to the transaction during the three and six months ended June 30, 2024, respectively, which are included in the unaudited condensed consolidated statements of operations and comprehensive income (loss) in its income from continuing operations under the line item, General and administrative.

As of December 1, 2023, the results of Datos’ operations are included within the Company’s consolidated financial statements. This business combination did not have a material impact on the Company’s consolidated financial statements. Therefore, actual results of operations subsequent to the acquisition date and pro forma results of operations have not been presented.

Traffic Think Tank

On February 23, 2023, the Company completed a purchase agreement with Rank, LLC (“Traffic Think Tank”), acquiring certain intangible assets of Traffic Think Tank for total cash consideration of $1,800, of which $360 was paid during February 2024 (the “12-month holdback amount”) and $360 will be paid in 18 months (the “18-month holdback amount”). The remaining consideration was paid upon closing. The 18-month holdback amount is recorded in other current liabilities in the unaudited condensed consolidated balance sheet as of June 30, 2024. The primary purpose of the acquisition was to acquire valuable brand and content related to Traffic Think Tank’s SEO community and courses.

12.    Income Taxes

The Company is subject to income taxes in U.S. federal, state, and foreign jurisdictions. For the three and six months ended June 30, 2024, the Company recorded provisions for income taxes of $4,649 and $7,753, respectively. For the three and six months ended June 30, 2023, the Company recorded provisions for income taxes of $869 and $1,666, respectively. The Company’s effective tax rate for the six months ended June 30, 2024 differs from the U.S. statutory rate due primarily to the impact of earnings in foreign jurisdictions and the impact of the requirement to capitalize and amortize certain research and development costs which results in a current U.S. tax provision but no deferred tax benefit as a result of the valuation allowance maintained against our net deferred tax assets. The Company’s income tax expense for the three and six months ended June 30, 2023, respectively, primarily relates to income earned in certain foreign jurisdictions.

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. These differences are measured using the enacted statutory tax rates that are expected to be in effect for the years in which differences are expected to reverse. On a periodic basis, the Company reassesses any valuation allowances it maintains on its deferred tax assets, weighing positive and negative evidence to assess the recoverability of the deferred tax assets. The Company maintains a valuation allowance on its net deferred tax assets.

13.    Stockholders’ Equity

Common Stock Reserved for Future Issuance

As of June 30, 2024, the Company had reserved the following shares of common stock for future issuance:

During the three and six months ended June 30, 2024, a total of 409,801 shares of Class B Common Stock were converted to Class A Common Stock.

25

14.    Stock-Based Compensation

The Company recorded stock-based compensation expense of $7,166 and $12,281 during the three and six months ended June 30, 2024, respectively, and recorded $3,765 and $6,561 during the three and six months ended June 30, 2023, respectively. The following table shows stock-based compensation expense by where the stock-based compensation expense is recorded in the Company’s unaudited condensed consolidated statement of operations:

	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Cost of revenue	$	59	$	32	$	98	$	49
Sales and marketing	1,209		840		1,979		1,368
Research and development	1,371		542		2,007		885
General and administrative	4,527		2,351		8,197		4,259
Total stock-based compensation	$	7,166	$	3,765	$	12,281	$	6,561

As of June 30, 2024, there was $14,052 of unrecognized compensation cost related to unvested common stock option arrangements, which is expected to be recognized over a weighted-average period of 2.43 years. As of June 30, 2024, there was $46,162 of unrecognized compensation cost related to unvested restricted stock unit awards, which is expected to be recognized over a weighted-average period of 2.57 years. As of June 30, 2024, there was $22,435 of unrecognized compensation cost related to unvested performance stock unit awards, which is expected to be recognized over a weighted-average period of 3.29 years.

The fair value of each option award was estimated on the date of grant using the Black-Scholes option-pricing model. As there was no public market for its common stock prior to March 25, 2021, which was the first day of trading, and as the trading history of the Company’s common stock is limited, the Company determined the expected volatility for options granted based on an analysis of reported data for a peer group of companies that issued options with substantially similar terms. The expected volatility of options granted has been determined using an average of the historical volatility measures of this peer group of companies. The expected life of options granted to employees was calculated using the simplified method, which represents the average of the contractual term of the option and the weighted-average vesting period of the option. The Company uses the simplified method because it does not have sufficient historical option exercise data to provide a reasonable basis upon which to estimate expected term. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected life of the share option. The Company has not paid, nor anticipates paying, cash dividends on its ordinary shares; therefore, the expected dividend yield is assumed to be zero.

26

The weighted-average assumptions utilized to determine the fair value of options granted to employees are presented in the following table:

	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Expected volatility	—	%	63.0	%	61.8	%	63.2	%
Weighted-average risk-free interest rate	—	%	3.48	%	4.28	%	3.70	%
Expected dividend yield	—		—		—		—
Expected life – in years	—		6		6		6

A summary of the Company’s option activity as of June 30, 2024, and changes during the six months then ended are as follows:

Pursuant to these agreements, the Company indemnifies and agrees to reimburse the indemnified party for losses suffered or incurred as a result of claims of intellectual property infringement. These indemnification agreements are provisions of the applicable customer agreement. Based on when clients first sign an agreement for the Company’s service, the maximum potential amount of future payments the Company could be required to make under certain of these indemnification agreements is unlimited. Based on historical experience and information known as of June 30, 2024, the Company has not incurred any costs for the above guarantees and indemnities.

In certain circumstances, the Company warrants that its services will perform in all material respects in accordance with its standard published specification documentation in effect at the time of delivery of the services to the customer for the term of the agreement. To date, the Company has not incurred significant expense under its warranties and, as a result, the Company believes the estimated fair value of these agreements is immaterial.

17.    Segment and Geographic Information

Disclosure requirements about segments of an enterprise and related information establishes standards for reporting information regarding operating segments in annual financial statements and requires selected information of those segments to be presented in interim financial reports issued to shareholders. Operating segments are defined as components of an enterprise about which separate discrete financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is the chief executive officer. The Company and the chief executive officer view the Company’s operations and manage its business as one operating segment.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations together with the unaudited condensed consolidated financial statements, and related notes that are included elsewhere in this Quarterly Report on Form 10-Q, along with the financial information included in our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the Securities and Exchange Commission (the “SEC”) on March 7, 2024. Some of the information contained in this discussion and analysis, including information with respect to our planned investments in our research and development, sales and marketing, and general and administrative functions, contains forward-looking statements based upon current plans, beliefs, and expectations that involve risks, uncertainties, and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under the section titled “Special Note Regarding Forward-Looking Statements” and Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2023. Our historical results are not necessarily indicative of the results that may be expected for any period in the future.

Company Overview

We are a leading online visibility management SaaS platform, enabling companies globally to identify and reach the right audience in the right context and through the right channels. Online visibility represents how effectively companies connect with consumers across a variety of digital channels, including search, social and digital media, digital public relations, and review websites. Our proprietary SaaS platform enables us to aggregate and enrich trillions of data points collected from hundreds of millions of unique domains, social media platforms, online ads, and web traffic. This allows our customers to understand trends, derive unique and actionable insights to improve their websites and social media pages, and distribute highly relevant content to their targeted customers across channels to drive high quality traffic.

We generate substantially all of our revenue from monthly and annual subscriptions to our online visibility management platform under a SaaS model. Subscription revenue is recognized ratably over the contract term beginning on the date the product is made available to customers.

We currently operate subsidiaries in the United States, Spain, the Czech Republic, the Netherlands, Cyprus, Serbia, Poland, Germany, Armenia, Canada, Vietnam, and France.

Our revenue is primarily generated through sales of our products around the globe. The largest portion of our revenue continues to be driven by customers based in the U.S. and UK, generating combined revenues of $51.3 million and $100.2 million for the three and six months ended June 30, 2024, respectively, and $42.1 million and $83.8 million for the three and six months ended June 30, 2023, respectively.

We have one reportable segment. See Note 17 to the unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for more information.

Key Factors Affecting Our Performance

We regularly review a number of factors that have impacted, and we believe will continue to impact, our results of operations and growth. These factors include:

Acquiring New Paying Customers

We expect increasing demand for third-party online visibility software to accelerate adoption of our platform. Our recurring subscription model provides significant visibility into our future results and we

31

believe Annual Recurring Revenue (“ARR”) is the best indicator of the scale of our platform, while mitigating fluctuations due to seasonality and contract term. We define ARR as of a given date as the monthly recurring revenue that we expect to contractually receive from all paid subscription agreements that are actively generating revenue as of that date multiplied by 12. We include both monthly recurring paid subscriptions, which renew automatically unless canceled, as well as annual recurring paid subscriptions so long as we do not have any indication that a customer has canceled or intends to cancel its subscription and we continue to generate revenue from them. As of June 30, 2024, we had over 116,000 paying customers, accounting for $377.7 million in ARR, an increase from more than 104,000 paying customers accounting for $302.4 million in ARR as of June 30, 2023.

Retaining and Expanding Sales to Our Existing Customers

We serve a diverse customer base across a variety of sizes and industries that is focused on maximizing their online visibility. We believe there is significant opportunity to expand within our existing customer base as customers often initially purchase our entry-level subscription, which offers lower usage limits and limited user licenses, as well as fewer features. We have demonstrated the ability to expand contract values with our existing customers as they use our products and recognize the critical nature of our platform and often seek premium offerings through incremental usage, features, add-ons, and additional user licenses.

Our dollar-based net revenue retention rate enables us to evaluate our ability to retain and expand subscription revenue generated from our existing customers. Our dollar-based net revenue retention rate as of June 30, 2024 and December 31, 2023 was approximately 107%.

We calculate our dollar-based net revenue retention rate as of the end of a period by using (a) the revenue from our customers during the twelve month period ending one year prior to such period as the denominator and (b) the revenue from those same customers during the twelve months ending as of the end of such period as the numerator. This calculation excludes revenue from new customers and any non-recurring revenue.

We have successfully increased ARR per paying customer over time and believe this metric is an indicator of our ability to grow the long-term value of our platform. We expect ARR per paying customer to continue to increase as customers adopt our premium offerings and we continue to introduce new products and functionality. Our ARR per paying customer as of June 30, 2024 and June 30, 2023 was $3,253 and $2,904, respectively, in absolute unrounded amounts. We define ARR per paying customer as of a given date as ARR from our paying customers as of that date divided by the number of paying customers as of that date. We define the number of paying customers as the number of unique business and individual customers as of a given date. We define a business customer as all accounts that contain a common non-individual business email domain (e.g., all subscriptions with an email domain of @XYZ.com will be considered to be one customer), and an individual customer as an account that uses an individual non-business email domain.

Sustaining Product and Technology Innovation

We have a strong track record of developing new products that have high adoption rates among our paying customers. Our product development organization plays a critical role in continuing to enhance the effectiveness and differentiation of our technology in an evolving landscape and maximizing retention of our existing customers. We intend to continue investing in product development to improve our data assets, expand our products and enhance our technological capabilities.

32

Non-GAAP Financial Measures

In addition to our financial results determined in accordance with U.S. generally accepted accounting principles (“GAAP”), we believe that non-GAAP income (loss) from operations, non-GAAP income (loss) from operations margin, free cash flow and free cash flow margin, each a non-GAAP financial measure, are useful in evaluating the performance of our business.

Non-GAAP income (loss) from operations, non-GAAP income (loss) from operations margin, free cash flow and free cash flow margin

We define non-GAAP income (loss) from operations as GAAP income (loss) from operations, excluding stock-based compensation, amortization of acquired intangible assets, acquisition related costs, restructuring costs and other one-time expenses outside the ordinary course of business (for example, our Exit Costs incurred primarily in 2022). We define non-GAAP operating margin as non-GAAP income (loss) from operations divided by GAAP revenue. We believe investors may want to consider our results with and without the effects of these items in order to compare our financial performance with that of other companies that exclude such items and to compare our results to prior periods. We monitor non-GAAP income (loss) from operations and non-GAAP income (loss) from operations margin as two measures of our overall business performance, which enables us to analyze our future performance and allows us to better understand the operating results of our business. We define free cash flow, a non-GAAP financial measure, as net cash provided by (used in) operating activities less purchases of property and equipment and capitalized software development costs. We define free cash flow margin as free cash flow divided by GAAP revenue. We monitor free cash flow and free cash flow margin as two measures of our overall business performance, which enables us to analyze our future performance without the effects of non-cash items and allows us to better understand the cash needs of our business. While we believe that non-GAAP income (loss) from operations, non-GAAP income (loss) from operations margin, free cash flow and free cash flow margin are useful in evaluating our business, non-GAAP income (loss) from operations and non-GAAP income (loss) from operations margin, free cash flow and free cash flow margin are each non-GAAP financial measures that have limitations as an analytical tool, and non-GAAP income (loss) from operations and non-GAAP income (loss) from operations margin should not be considered as an alternative to, or substitute for, income (loss) from operations in accordance with GAAP and free cash flow and free cash flow margin should not be considered as an alternative to, or substitute for, net cash provided by (used in) operating activities in accordance with GAAP. The utility of free cash flow and free cash flow margin as a measure of our liquidity is further limited as each measure does not represent the total increase or decrease in our cash balance for any given period. In addition, other companies, including companies in our industry, may calculate free cash flow and free cash flow margin differently or not at all, which reduces the usefulness of free cash flow and free cash flow margin as a tool for comparison. A summary of our cash flows from operating, investing, and financing activities is provided below. We recommend that you review the reconciliation of GAAP income (loss) from operations to non-GAAP income (loss) from operations, the reconciliation of GAAP income (loss) from operations margin to non-GAAP income (loss) from operations margin, the most directly comparable GAAP financial measure, provided below, the reconciliation of free cash flow to net cash provided by (used in) operating activities, the most directly comparable GAAP financial measure, and the reconciliation of free cash flow margin to net cash provided by (used in) operating activities (as a percentage of revenue), the most directly comparable GAAP financial measure, and that you not rely on non-GAAP income (loss) from

33

operations, non-GAAP income (loss) from operations margin, free cash flow, free cash flow margin or any single financial measure to evaluate our business.

Components of our Results of Operations

Revenue

We generate nearly all of our revenue from subscriptions to our online visibility management platform under a SaaS model. Subscription revenue is recognized ratably over the contract term beginning on the date on which we provide the customer access to our platform. Our customers do not have the right to take possession of our software. Our subscriptions are generally non-cancellable during the contractual subscription term, however our subscription contracts contain a right to a refund if requested within seven days of purchase.

We offer our paid products to customers via monthly or annual subscription plans, as well as one-time and ongoing add-ons. Our subscription-based model enables customers to select a plan based on their needs and license our platform on a per user per month basis.

As of June 30, 2024, we served over 116,000 paying customers in various industries, and our revenue is not concentrated with any single customer or industry. For the three and six months ended June 30, 2024, no single customer accounted for more than 10% of our revenue.

Cost of Revenue

Cost of revenue primarily consists of expenses related to hosting our platform, acquiring data, merchant account fees, and providing support to our customers. These expenses are comprised of personnel and related costs, including salaries, benefits, incentive compensation, and stock-based compensation expenses related to the management of our data centers, our customer support team, and our customer success team. In addition to these expenses, we incur third-party service provider costs, such as data center and networking expenses, data acquisition costs, allocated overhead costs, depreciation and amortization expense associated with our property and equipment, and amortization of capitalized software development costs and intangible assets acquired through business combinations and asset acquisitions. We allocate overhead costs, such as rent and facility costs, certain information technology and data analytics costs, and employee benefit costs to all departments based primarily on headcount. As such, general overhead expenses are reflected in cost of revenue and each operating expense category.

We expect our cost of revenue to increase in absolute dollars due to expenditures related to the purchase of hardware, data, expansion, and support of our data center operations and customer support/success teams. We have seen improvement in our cost of revenue as a percentage of revenue, and expect it to remain near current levels. It may fluctuate from period to period depending on the timing of significant expenditures. To the extent that our customer base grows, we intend to continue to invest additional resources in expanding the delivery capability of our products and other services. The timing of these additional expenses could affect our cost of revenue, both in terms of absolute dollars and as a percentage of revenue in any particular quarterly or annual period.

Operating Expenses

Sales and Marketing

Sales and marketing expenses primarily consist of personnel and related costs directly associated with our sales and marketing department, including salaries, benefits, incentive compensation, and stock-based compensation, online advertising expenses, and marketing and promotional expenses, as well as allocated overhead costs. We expense all costs as they are incurred, excluding sales commissions identified as incremental costs to obtain a contract, which are capitalized and amortized on a straight-line basis over the average period of benefit, which we estimate to be two years. We expect that our sales and marketing expenses will fluctuate as a percentage of revenue based on the timing of related costs.

35

New sales personnel require training and may take several months or more to achieve productivity; as such, the costs we incur in connection with the hiring of new sales personnel in a given period are not typically offset by increased revenue in that period and may not result in new revenue if these sales personnel fail to become productive.

Research and Development

Research and development expenses primarily consist of personnel and related costs, including salaries, benefits, incentive compensation, stock-based compensation, and allocated overhead costs. Research and development expenses also include depreciation expense and other expenses associated with product development. Other than internal-use software costs that qualify for capitalization, research and development costs are expensed as incurred. We plan to increase the dollar amount of our investment in research and development for the foreseeable future as we focus on developing new products, features, and enhancements to our platform. We believe that investing in the development of new products, features, and enhancements improves customer experience, makes our platform more attractive to new paying customers, and provides us with opportunities to expand sales to existing paying customers and convert free customers to paying customers.

General and Administrative

General and administrative expenses primarily consist of personnel and related expenses, including salaries, benefits, incentive compensation, and stock-based compensation, associated with our finance, legal, human resources, IT, and other administrative employees. Our general and administrative expenses also include professional fees for external legal, accounting, and other consulting services, insurance, depreciation and amortization expense, as well as allocated overhead. We expect to increase the size of our general and administrative functions to support the growth of our business. We expect to continue to incur additional expenses as a result of operating as a public company, including costs to comply with rules and regulations applicable to companies listed on a U.S. securities exchange, costs related to compliance and reporting obligations pursuant to the rules and regulations of the SEC, increases in insurance premiums, investor relations and professional services. We expect our general and administrative expenses to decrease as a percentage of revenue over time.

Exit Costs

All costs associated with our relocation efforts are included in the unaudited condensed consolidated statement of operations in our income from continuing operations under the line item, Exit Costs. Exit costs in connection with our relocation efforts include employee severance and fringe benefit costs and other associated relocation costs. We do not expect to incur exit costs associated with relocation efforts in future periods.

Other Income, Net

Included in other income, net are foreign currency transaction gains and losses. In accordance with ASC 830, Foreign Currency Matters, we redetermined our functional currencies of our international locations as of January 1, 2022, when it was determined the local currencies for these regions were most appropriate. For the three and six months ended June 30, 2024, the functional currencies of our international locations were the local currencies for these regions. Any differences resulting from the re-measurement of assets and liabilities denominated in a currency other than the functional currency are recorded within other income, net. We expect our foreign currency exchange gains and losses to continue to fluctuate in the future as foreign currency exchange rates change.

Other income, net also includes amounts for interest income and expense, other miscellaneous income and expense, and gains and losses unrelated to our core operations. We have elected the fair value option in respect to the accounting for our convertible note investments, allowing for increases and

36

decreases in the fair value of such investments to be recorded to other income, net for each reporting period. Interest expense is related to our finance leases.

Income Tax Provision

We operate in several tax jurisdictions and are subject to taxes in each country or jurisdiction in which we conduct business. We account for income taxes in accordance with the asset and liability method. Under this method, 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. In addition, this method requires a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. To date, we have incurred cumulative net losses and maintain a full valuation allowance on our net deferred tax assets. Our tax expense for the three and six months ended June 30, 2024 primarily relates to the tax provision recorded on the earnings of our profitable foreign subsidiaries and the requirement to capitalize and amortize certain research and development costs which results in a current U.S. tax provision but no deferred tax benefit as a result of the valuation allowance maintained against our net deferred tax assets. Our tax expense for the three and six months ended June 30, 2023 primarily relates to income earned in certain foreign jurisdictions.

Comparison of the Three and Six Months Ended June 30, 2024 and 2023

Revenue

Our revenue during the three and six months ended June 30, 2024 and 2023 was as follows:

	Three Months Ended June 30,				Change				Six Months Ended June 30,				Change
	2024		2023		Amount		%		2024		2023		Amount		%
	(dollars in thousands)								(dollars in thousands)
Revenue	$	90,951	$	74,693	$	16,258	22	%	$	176,763	$	145,563	$	31,200	21	%

Revenue increased in all regions. The majority of this increase was driven by an increase in the number of paying customers from over 104,000 as of June 30, 2023 to over 116,000 as of June 30, 2024. The increases in revenue for the three and six months ended June 30, 2024 were also driven by growth in user licenses per customer, attach rates, and increased revenue per customer related to larger customers. We define attach rates as the ratio of the number of paying customers who purchase specific add-ons to the number of total paying customers.

For the three months ended June 30, 2024, cost of revenue increased by $2.0 million compared to the corresponding period of the prior year. This increase is primarily driven by a $0.7 million increase in depreciation and amortization costs related to increased capitalized software and intangible asset amortization, a $0.5 million increase related to increased allocation of IT costs to cost of revenue, $0.4 million increase in integration and data costs, and a $0.4 million increase in merchant fees.

For the six months ended June 30, 2024, cost of revenue increased by $4.0 million compared to the corresponding period of the prior year. This increase is primarily driven by a $1.2 million increase in depreciation and amortization costs related to increased capitalized software and intangible asset amortization, a $1.2 million increase in integration and data costs, a $0.9 million increase related to increased allocation of IT costs to cost of revenue, and a $0.7 million increase in merchant fees.

For the three months ended June 30, 2024, sales and marketing expense increased by $4.8 million compared to the corresponding period of the prior year. This increase was primarily driven by a $2.7 million increase in personnel costs as a result of higher contractor and commission costs as well as a $1.1 million increase related to increased allocation of IT costs to sales and marketing.

For the six months ended June 30, 2024, sales and marketing expense increased by $3.2 million compared to the corresponding period of the prior year. This increase was primarily driven by a $6.2 million increase in personnel costs primarily driven by increased contractor, stock-based compensation, and commission costs as well as a $1.7 million increase related to increased allocation of IT costs to sales and marketing, partially offset by a $5.6 million decrease in marketing and advertising expense due to lower paid search costs.

Research and Development

	2024			2023			Amount		%		2024			2023			Amount		%

Percentage of total revenue	21		%	19		%					21		%	19		%

For the three months ended June 30, 2024, research and development costs increased by $5.2 million compared to the corresponding period of the prior year, primarily as a result of a $2.2 million increase in personnel costs driven by a 9% increase in headcount compared to the corresponding period of the prior year and increased stock-based compensation costs, a $1.2 million increase to other costs, primarily driven by increases to outsourcing, and a $0.7 million increase related to IT and other allocations.

For the six months ended June 30, 2024, research and development costs increased by $8.6 million compared to the corresponding period of the prior year, primarily as a result of a $3.6 million increase in personnel costs driven by a 9% increase in headcount compared to the corresponding period of the prior year, a $1.6 million increase related to IT and other allocations, and a $1.4 million increase to other costs, primarily driven by increases to outsourcing.

For the three months ended June 30, 2024, general and administrative expense decreased by $1.1 million compared to the corresponding period of the prior year. This decrease was primarily driven by a $2.3 million increase in costs allocated from general and administrative expense to other departments, and a $1.7 million decrease to other costs. This decrease was partially offset by a $2.5 million increase in personnel costs, which includes a $2.2 million increase in stock-based compensation, and a $0.4 million

41

increase to professional services, primarily driven by an increase in consulting fees and acquisition-related costs.

For the six months ended June 30, 2024, general and administrative expense decreased by $1.2 million compared to the corresponding period of the prior year. This decrease was primarily driven by a $4.3 million increase in costs allocated from general and administrative expense to other departments, a $1.7 million decrease to other costs, and a $0.8 million decrease to professional services, primarily driven by a decrease in consulting fees. This decrease was partially offset by a $5.5 million increase in personnel costs, which includes a $3.9 million increase in stock-based compensation.

Exit Costs

All costs associated with our relocation efforts are included in the unaudited condensed consolidated statement of operations in our income from continuing operations under the line item, Exit Costs. Exit costs in connection with our relocation efforts include employee severance and fringe benefit costs, and other associated relocation costs.

During the three and six months ended June 30, 2024, respectively, exit costs were not incurred. During the three and six months ended June 30, 2023 exit costs totaled $0.3 million and $1.3 million, respectively, related to our relocation efforts.

Other Income, Net

Percentage of total revenue	3		%	4		%				4		%	3		%

The decrease in other income for the three months ended June 30, 2024 compared to the corresponding period of the prior year was primarily due to a convertible note fair value adjustment in the prior period, with no corresponding increase in the current period. The increase in other income for the six months ended June 30, 2024 compared to the corresponding period of the prior year was primarily due to increases in foreign currency exchange gain (loss) and interest income, net.

Provision for Income Taxes

	Three Months Ended June 30,						Change				Six Months Ended June 30,						Change
	2024			2023			Amount		%		2024			2023			Amount		%

Percentage of total revenue	5		%	1		%					4		%	1		%

The increase in the provision for income taxes for the three and six months ended June 30, 2024 compared to the corresponding periods of the prior year was primarily due to the effects of changes in the tax provision recorded on the earnings of our profitable foreign subsidiaries and the impact of the requirement to capitalize and amortize certain research and development costs which results in a current provision for U.S. taxes but no deferred tax benefit as a result of the valuation allowance maintained against our net deferred tax assets.

42

Liquidity and Capital Resources

Our principal sources of liquidity have been the net proceeds of our initial public offering in March 2021 and our follow-on offering in November 2021, which totaled $213.8 million, after deducting underwriting discounts and offering expenses paid or payable by us, and the net proceeds we received through private sales of equity securities, as well as sales of premium subscriptions to our platform.

As of June 30, 2024, we had cash and cash equivalents of $69.6 million, short-term investments of $161.9 million, and accounts receivable of $9.1 million.

Our principal uses of cash in recent periods have been to fund operations, invest in capital expenditures and short-term investments, and strategically acquire new businesses. This cash is held in deposits and money market funds.

We believe our existing cash, cash equivalents, and short-term investments will be sufficient to meet our operating and capital needs for at least the next 12 months. Our future capital requirements will depend on many factors, including those set forth under Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2023.

In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us, or at all. If we are unable to raise additional capital or generate cash flows necessary to expand our operations, our business, results of operations, and financial condition could be adversely affected.

Operating Activities

Our largest source of operating cash is cash collections from our customers for subscription services. Our primary uses of cash from operating activities are for online advertising, personnel costs across the sales and marketing, product and development, and general and administrative departments, and hosting costs.

Net cash provided by operating activities during the six months ended June 30, 2024 was $26.9 million. The activity resulted from a net income of $3.4 million adjusted for non-cash add backs of $24.0 million and a net cash outflow of $0.4 million from changes in operating assets and liabilities during the six months ended June 30, 2024. Non-cash charges primarily consisted of $12.3 million of stock-based compensation expense and $6.1 million for amortization of deferred contract acquisition costs related to capitalized commissions. The changes in operating assets and liabilities were primarily the result of a $6.1 million increase in deferred contract costs, a $4.0 million increase in prepaid expenses and other current assets, a $2.1 million decrease in operating lease liability, and a $0.8 increase in accounts receivable. These outflows were partially offset by a $7.4 million increase in deferred revenue, a $2.9 million increase in accrued expenses, and a $1.9 million increase in accounts payable.

Net cash used in operating activities during the six months ended June 30, 2023 was $9.9 million as compared to the $0.6 million provided by operating activities during the six months ended June 30, 2022. The activity resulted from a net loss of $10.1 million adjusted for non-cash add backs of $13.7 million and a net cash outflow of $13.5 million from changes in operating assets and liabilities during the six months ended June 30, 2023. Non-cash charges primarily consisted of $4.9 million for amortization of deferred contract acquisition costs related to capitalized commissions, $3.1 million of depreciation and amortization expense, and $6.6 million of stock-based compensation expense. The changes in operating assets and liabilities were primarily the result of a $5.2 million decrease in accounts payable and a $5.8 million increase in deferred contract costs. These outflows were partially offset by a $7.0 million increase in deferred revenue due to the addition of new customers and expansion of the business.

43

Investing Activities

Net cash used in investing activities for the six months ended June 30, 2024 was $6.2 million and primarily consisted of $83.6 million in purchases of short-term investments, $10.0 million in cash paid for businesses, net of cash acquired, $7.0 million in funding of the investment loan receivable, $4.4 million in capitalization of internal-use software costs, and $2.9 million in purchases of property and equipment. This activity was partially offset by $102.5 million in proceeds from sales and maturities of short-term investments.

Net cash used in investing activities for the six months ended June 30, 2023 was $45.1 million and primarily consisted of $172.7 million in purchases of short-term investments. This activity was partially offset by $132.7 million in proceeds from sales and maturities of short-term investments.

Financing Activities

Net cash provided by financing activities for the six months ended June 30, 2024 was $2.6 million and consisted of $3.1 million relating to the exercise of stock options partially offset by $0.5 million of cash outflows related to the payment of finance leases.

Net cash used in financing activities for the six months ended June 30, 2023 was $0.6 million and consisted of $1.2 million of cash outflows related to the payment of finance leases partially offset by inflows of $0.3 million related to proceeds from shares issued in connection with the Employee Stock Purchase Plan as well as $0.3 million relating to the exercise of stock options.

Contractual Obligations and Commitments

Our principal commitments consist of obligations under leases for office space and leases for data center facilities. For more information regarding our lease obligations, see Note 4 to the unaudited condensed consolidated financial statements of this Quarterly Report on Form 10-Q. In addition to our leases, we also have multi-year commitments with certain data providers expiring at various dates through 2026. For more information regarding our commitments with data providers, see Note 15 to the unaudited condensed consolidated financial statements of this Quarterly Report on Form 10-Q. We expect to fund these obligations with cash flows from operations and cash on our balance sheet.

Recent Accounting Pronouncements

See the section titled “Recent Accounting Pronouncements Not Yet Adopted” in Note 2 to the unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for more information.

Critical Accounting Policies and Estimates

Our unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States. The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and assumptions. Our actual results may differ from these estimates.

Our critical accounting policies and estimates are described under the heading Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies

44

and Estimates in our Annual Report on Form 10-K for the year ended December 31, 2023 and in Note 2 to the unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in foreign currency exchange rates, interest rates, and inflation. We do not hold or issue financial instruments for trading purposes.

Interest Rate Risk

We are exposed to market risk related to changes in interest rates. Our investments primarily consist of short-term investments and money market funds. As of June 30, 2024 we had cash, cash equivalents, and short-term investments of $231.5 million. The carrying amount of our cash and cash equivalents reasonably approximates fair value, due to the short maturities of these investments. The primary objectives of our investment activities are the preservation of capital, the fulfillment of liquidity needs and the fiduciary control of cash and investments. We are obligated by our investment policy to invest the majority of our portfolio into U.S. government securities. We do not enter into investments for trading or speculative purposes. Our short-term investments are exposed to market risk due to a fluctuation in interest rates, which may affect our interest income and the fair market value of our investments. Due to the short-term nature of our investment portfolio, we believe only dramatic fluctuations in interest rates would have a material effect on our investments. We do not believe that an immediate 10% increase in interest rates would have a material effect on the fair market value of our portfolio. As such we do not expect our operating results or cash flows to be materially affected by a sudden change in market interest rates.

Foreign Currency Exchange Risk

We are not currently subject to significant foreign currency exchange risk with respect to revenue as our U.S. and international sales are predominantly denominated in U.S. dollars. However, we have some foreign currency risk related to a small amount of sales denominated in euros, and expenses denominated in euros and other currencies. Sales denominated in euros reflect the prevailing U.S. dollar exchange rate on the date of invoice for such sales. Increases in the relative value of the U.S. dollar to the euro may negatively affect revenue and other operating results as expressed in U.S. dollars. We incur significant expenses outside the United States denominated in foreign currencies, primarily the euro. In connection with our operations in Europe with expenses in euros and other currencies, we are exposed to some increased foreign currency exchange risk related to additional expenses denominated in euros. If the average exchange rates of any of these foreign currencies strengthen against the dollar, the dollar value of our expenses outside the United States will increase. For example, an immediate 10% decrease or increase in the relative value of the U.S. dollar to the euro would result in a $4.8 million gain or loss on our unaudited condensed consolidated statements of operations and cash flows.

We have not engaged in the hedging of foreign currency transactions to date. However, as our international operations expand, our foreign currency exchange risk may increase. If our foreign currency exchange risk increases in the future, we may evaluate the costs and benefits of initiating a foreign currency hedge program in connection with non-U.S. dollar denominated transactions.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, including our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on management’s evaluation as of the quarter ended June 30, 2024, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of June 30, 2024.

Our management believes the unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial condition, results of operations and cash flows as of and for the periods presented in accordance with U.S. GAAP.

Changes in Internal Control Over Financial Reporting

There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter ended June 30, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitation in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Due to inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

46

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the ultimate costs to resolve any pending matter will not have a material adverse effect on our business, operating results, financial condition, or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Item 1A. Risk Factors

We have included in Part I, Item 1A, “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2023, a description of certain risks and uncertainties associated with our business (the “Risk Factors”). You should carefully consider the Risk Factors before making a decision to invest in our securities.

These risks include, but are not limited to, rapid technological change, competitive pressure from substitute products or larger companies, protection of proprietary technology, management of international activities, and dependence on third parties and key individuals.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

The unaudited condensed consolidated interim financial statements have been prepared on the same basis as the audited annual consolidated financial statements as of and for the year ended December 31, 2023, and, in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of June 30, 2024, and for the three and six months ended June 30, 2024 and 2023. The consolidated balance sheet as of December 31, 2023 included herein was derived from the audited consolidated financial statements as of that date.

The results for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024, any other interim periods, or any future year or period.

The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 7, 2024.

The accompanying unaudited condensed consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to the unaudited condensed consolidated financial statements. As of June 30, 2024, there have been no material changes in the Company's significant accounting policies from those that were disclosed in the Annual Report on Form 10-K, except as discussed below.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, and subsidiaries in which it holds a controlling interest. All intercompany transactions and balances have been eliminated in consolidation. Ownership interests in subsidiaries represented by other parties that do not control the entity are presented in the consolidated financial statements as activities and balances attributable to noncontrolling interests.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Significant estimates relied upon in preparing these unaudited condensed consolidated financial statements include, but are not limited to, revenue recognition, expected future cash flows used to evaluate the recoverability of long-lived assets, contingent liabilities, expensing and capitalization of research and development costs for internal-use software, the average period of benefit associated with costs capitalized to obtain revenue contracts, the determination of the fair value of stock-based awards issued, stock-based compensation expense, the determination of the estimated fair value of loan receivables and convertible notes held by the Company, the valuations of the intangible assets acquired through acquisitions, the estimation of the Company’s incremental borrowing rate, and the recoverability of the Company’s net deferred tax assets and related valuation allowance.

Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made.

Subsequent Events Considerations

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the unaudited condensed consolidated financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. See Note 18 for additional information regarding the Company’s subsequent events.

Emerging Growth Company Status

The Company is an "emerging growth company" (“EGC”), as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”). Based on the market value of our common equity held by non-affiliates as of June 28, 2024 (the last business day of our most recently completed second fiscal quarter), we will cease to qualify as an emerging growth company as of the end of the fiscal year ending December 31, 2024. As a result, beginning with our Annual Report on Form 10-K for the year ending December 31, 2024, we will be subject to certain requirements that apply to other public companies but did not previously apply to us due to our status as an emerging growth company, including the provisions of Section 404 of the Sarbanes-Oxley Act, which require that our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting.

Revenue Recognition

The Company primarily derives revenue from subscriptions to the Company’s SaaS services and related customer support. For the three and six months ended June 30, 2024 and 2023, subscription revenue accounted for nearly all of the Company’s revenue. Revenue related to other revenue was not material for the three and six months ended June 30, 2024 and 2023.

The Company offers subscriptions to its platform primarily on a monthly or annual basis. The Company sells its products and services primarily through a self-service model and also directly through its sales force. The Company’s subscription arrangements provide customers the right to access the Company’s hosted software applications. Customers do not have the right to take possession of the Company’s software during the hosting arrangement. Subscriptions are generally non-cancellable during the contractual subscription term; however, subscription contracts contain a right to a refund if requested within seven days of purchase.

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration it expects to receive in exchange for those products or services. There were no changes to the Company’s revenue recognition policies since the filing of its Annual Report on Form 10-K with the SEC on March 7, 2024.

Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. The Company primarily invoices and collects payments from customers for its services in advance on a monthly or annual basis.

Deferred revenue represents amounts billed for which revenue has not yet been recognized. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as deferred revenue, and the remaining portion is recorded as deferred revenue, net of current portion. Deferred revenue increased by $8,185 as of June 30, 2024 compared to December 31, 2023. During the three and six months ended June 30, 2024, $32,354 and $39,426 of revenue was recognized that was included in deferred revenue at the beginning of each respective period. During the three and six months ended June 30, 2023, $27,865 and $37,831 of revenue was recognized that was included in deferred revenue at the beginning of each respective period.

The Company has elected to exclude amounts charged to customers for sales tax from the transaction price. Accordingly, revenue is presented net of any sales tax collected from customers.

Transaction Price Allocated to Future Performance Obligations

ASC 606 requires that the Company disclose the aggregate amount of the transaction price that is allocated to performance obligations that have not yet been satisfied as of the balance sheet dates reported.

For contracts with an original expected duration greater than one year, the aggregate amount of the transaction price allocated to the performance obligations that were unsatisfied as of June 30, 2024 was $1,207, of which the Company expects to recognize $970 over the next 12 months.

For contracts with an original expected duration of one year or less, the Company has applied the practical expedient available under ASC 606 to not disclose the amount of transaction price allocated to unsatisfied performance obligations as of June 30, 2024. For performance obligations not satisfied as of June 30, 2024, and to which this expedient applies, the nature of the performance obligations is consistent with performance obligations satisfied as of December 31, 2023.

Costs to Obtain a Contract

The incremental direct costs of obtaining a contract, which primarily consist of sales commissions paid for new subscription contracts, are deferred and recorded as deferred contract costs in the unaudited condensed consolidated balance sheets and are amortized over a period of approximately 24 months on a systematic basis, consistent with the pattern of transfer of the goods or services to which the asset relates. The 24-month period represents the estimated benefit period of the customer relationship and has been determined by taking into consideration the type of product sold, the commitment term of the customer contract, the nature of the Company’s technology development life-cycle, and an estimated customer relationship period based on historical experience and future expectations. Deferred contract costs that will be recorded as expense during the succeeding 12-month period are recorded as deferred contract costs, current portion, and the remaining portion is recorded as deferred contract costs, net of current portion. Amortization of deferred contract costs is included in sales and marketing expense in the accompanying unaudited condensed consolidated statements of operations and comprehensive income (loss).

Concentrations of Credit Risk and Significant Customers

The Company has no off-balance sheet risk, such as foreign exchange contracts, option contracts, or other hedging arrangements. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. 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.

Credit risk with respect to accounts receivable is dispersed due to the large number of customers of the Company. The Company routinely assesses the creditworthiness of its customers and generally does not require its customers to provide collateral or other security to support accounts receivable. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. 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.

As of June 30, 2024 and December 31, 2023, no individual customer represented more than 10% of the Company’s accounts receivable. During the three and six months ended June 30, 2024 and 2023, no individual customer represented more than 10% of the Company’s revenue.

Disclosure of Fair Value of Financial Instruments

The Company’s financial instruments include cash, cash equivalents, investments, accounts receivable, loan receivables, accounts payable, and accrued expenses. The Company’s investments are classified as available-for-sale and reported at fair value in accordance with the market approach utilizing quoted prices that were directly or indirectly observable. The Company has elected the fair value option in respect to the accounting for its loan receivable investment, resulting in increases and decreases in the fair value of such investments being recorded to other income, net for each reporting period. The carrying

amount of the remainder of the Company’s financial instruments approximated their fair values as of June 30, 2024 and December 31, 2023, due to the short-term nature of these instruments.

The Company has evaluated the estimated fair value of financial instruments using available market information. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts. See below for further discussion.

Foreign Currency Translation

The Company operates in a multi-currency environment having transactions in such currencies as the U.S. dollar, zloty, Czech koruna, euro, and others. The reporting currency of the Company is the U.S. dollar.

The foreign currency exchange gain (loss) included in other income, net for the three months ended June 30, 2024 and 2023 was $128 and $0, respectively. The foreign currency exchange gain (loss) included in other income, net for the six months ended June 30, 2024 and 2023 was $573 and $(638), respectively.

Comprehensive income (loss)

Comprehensive income (loss) is comprised of two components: net income (loss) and other comprehensive income (loss), which includes other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. For the three and six months ended June 30, 2024 and 2023, comprehensive income (loss) consists of net income (loss), the change in the cumulative foreign currency translation adjustment, and unrealized loss on investments. The tax effect of the cumulative foreign currency translation adjustment and unrealized loss on investments was not significant for the three and six months ended June 30, 2024 and 2023.

Recent Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. 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 evaluating the impact of adopting ASU 2023-07 on its consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740)-Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires that an entity disclose specific categories in the effective tax rate reconciliation as well as provide additional information for reconciling items that meet a quantitative threshold. Further, ASU 2023-09 requires certain disclosures of state versus federal income tax expense and taxes paid. The amendments in ASU 2023-09 are required to be adopted for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied on a prospective basis although retrospective application is permitted. The Company is evaluating the impact of adopting ASU 2023-09 on its consolidated financial statements and disclosures.

Cash, Cash Equivalents, Restricted Cash, and Investments

Cash and Cash Equivalents [Abstract]

Cash, Cash Equivalents, Restricted Cash, and Investments

Cash, Cash Equivalents, Restricted Cash, and Investments

The Company considers all highly liquid instruments purchased with an original maturity date of 90 days or less from the date of purchase to be cash equivalents. Cash and cash equivalents consist of cash

on deposit with banks and amounts held in interest-bearing money market funds. Cash equivalents are carried at cost, which approximates their fair market value. Short‑term investments consist of investments with original maturities greater than 90 days, as of the date of purchase. The Company considers its investment portfolio available-for-sale. The Company adjusts the cost of investments for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion in interest income in the unaudited condensed consolidated statements of operations.

When the Company holds debt investments classified as available-for-sale pursuant to ASC 320, Investments — Debt Securities, it records available-for-sale securities at fair value, with unrealized gains and losses included in accumulated other comprehensive loss in stockholders’ equity. The Company has classified its investments with maturities beyond one year as short term, based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. The Company includes interest and dividends on securities classified as available-for-sale in interest income in the unaudited condensed consolidated statements of operations and comprehensive income (loss). Realized gains and losses are recorded in the unaudited condensed consolidated statements of operations and comprehensive income (loss) based on the specific-identification method. There was no material realized gains or losses on investments for the three and six months ended June 30, 2024 or 2023. As of June 30, 2024 and December 31, 2023, the aggregate fair value of investments held by the Company in an unrealized loss position for less than twelve months was $88,741 and $89,381, respectively. As of June 30, 2024, the aggregate fair value of investments held by the Company in a continuous unrealized loss position for greater than twelve months was $55,382. The Company did not hold any investments in an unrealized loss position for greater than twelve months as of December 31, 2023.

On January 1, 2023, the Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) and ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815 Derivatives and Hedging and Topic 825, Financial Instruments. Under these standards, the Company reviews available-for-sale securities for impairment whenever the fair value of the security is less than its amortized cost. If impairment exists and the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis, the Company will write down the amortized cost basis to its fair value at the reporting date, recognizing the difference as a loss within other income, net in the unaudited condensed consolidated statements of operations. If the Company does not intend to sell the security nor is it more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis, the Company will determine if any portion of the unrealized loss on the security is due to credit loss. If the impairment is entirely or partially due to credit loss, the Company will measure the credit loss up to the amount of the difference between fair value and amortized cost, and recognize an allowance for credit losses along with the related charge against earnings as a loss within other income, net in the unaudited condensed consolidated statements of operations. The remaining impairment amount due to all other factors is recognized in accumulated other comprehensive income (loss) in the unaudited condensed consolidated balance sheets. Subsequent changes to the Company’s estimate of credit losses will be recorded as adjustments to the allowance for credit losses and other income, net. For the three and six months ended June 30, 2024, the Company determined that no impairments were required to be recognized in the unaudited condensed consolidated statements of operations.

The following is a summary of cash, cash equivalents, and investments as of June 30, 2024 and December 31, 2023:

	Amortized  Cost		Gross Unrealized Gains		Gross Unrealized Losses		Estimated Fair Value
June 30, 2024
Cash and cash equivalents	$	69,636	$	—	$	(10)	$	69,626

U.S. treasury securities	162,946		12		(1,052)		161,906
Total investments	162,946		12		(1,052)		161,906
Total cash, cash equivalents, and investments	$	232,582	$	12	$	(1,062)	$	231,532

	Amortized  Cost		Gross Unrealized Gains		Gross Unrealized Losses		Estimated Fair Value
December 31, 2023
Cash and cash equivalents	$	58,848	$	—	$	—	$	58,848
Investments:
U.S. treasury securities due in one year or less	179,843		265		(387)		179,721
Total investments	179,843		265		(387)		179,721
Total cash, cash equivalents and investments	$	238,691	$	265	$	(387)	$	238,569

The Company considered the extent to which any unrealized losses on its marketable securities were driven by credit risk and other factors, including market risk, and if it is more-likely-than-not that the Company would have to sell the security before the recovery of the amortized cost basis. As of June 30, 2024 and December 31, 2023, the unrealized losses related to its marketable securities were due to rising market interest rates compared to when the investments were initiated. The Company does not believe the unrealized losses represent credit risk, and the Company does not intend to sell any of the securities in an unrealized loss position and it is not likely that the Company would be required to sell these securities before recovery of their amortized cost basis, which may be at maturity. Thus, no credit loss was recognized for the Company's marketable securities for the three and six months ended June 30, 2024 and 2023.

As of June 30, 2024, the Company held $40,203 in U.S. treasury securities with maturities within one year and $121,703 in U.S. treasury securities with maturities after one year and within three years.

Restricted Cash

As of June 30, 2024, restricted cash totaled $11,903 and included $11,718 related to the Company’s Brand 24 tender offer (See Note 9) and $185 related to cash held as collateral for a letter of credit related to the contractual provisions for one of the Company’s office leases.

The following table is a reconciliation of cash, cash equivalents, and restricted cash included in the accompanying unaudited condensed consolidated balance sheets that sum to the total cash, cash equivalents, and restricted cash included in the accompanying unaudited condensed consolidated

Fair Value Measurement

Fair Value Measurement

The following tables summarize financial assets and liabilities measured and recorded at fair value on a recurring basis in the accompanying consolidated balance sheets as of June 30, 2024 and December 31, 2023, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

Liabilities:
Contingent consideration	$	—	$	—	$	597	$	597
Total liabilities	$	—	$	—	$	597	$	597

Cash equivalents include money market funds with original maturities of 90 days or less from the date of purchase. The fair value measurement of these assets is based on quoted market prices in active markets for identical assets and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 1 in the fair value hierarchy. The Company’s investments primarily consist of U.S. treasury securities. The fair value measurement of these assets is based on significant other observable inputs and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 2 in the fair value hierarchy.

As of June 30, 2024, the Company measured its investment loan receivables (see Note 7) and its contingent consideration associated with the acquisition of Datos Inc. on a recurring basis using significant unobservable inputs (Level 3). As of December 31, 2023, the Company measured its contingent consideration associated with the acquisition of Datos Inc. on a recurring basis using significant unobservable inputs (Level 3).

Contingent consideration

The Company records contingent consideration resulting from a business combination at its fair value on the acquisition date. The Company generally determines the fair value of the contingent consideration using the Monte Carlo simulation model. Each reporting period thereafter, these obligations are revalued and increases or decreases in their fair values are recorded as an adjustment to other income, net within the unaudited condensed consolidated statements of operations and comprehensive income (loss). Changes in the fair value of the contingent consideration can result from changes in assumed discount periods and rates, and from changes pertaining to the estimated or actual achievement of the defined milestones. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period. Accordingly, future business and economic conditions, as well as changes in any of the assumptions described above, can materially impact the amount of contingent consideration expense the Company records in any given period.

The total estimated fair value of the contingent consideration payable was $751 and $597 as of June 30, 2024 and December 31, 2023, respectively. The following table represents the key inputs used in the fair value calculations:

	June 30, 2024		December 31, 2023
Risk free interest rate	5.00	%	4.80	%
Projected year of payment	2025		2025
Revenue volatility	10.0	%	11.0	%
Discount rate	7.60	%	7.70	%

Changes in the estimated fair value of the Datos contingent consideration payable will be recognized in other income, net. A rollforward of the fair value measurements of the contingent consideration liability for the six months ended June 30, 2024 is as follows:

Balance as of December 31, 2023	$	597

Investment Loan Receivable

In March 2024, the Company entered into a loan agreement in which it has loaned $7,000 to the borrower with a repayment date in March 2025. In addition to the loan facility, the Company entered into an option agreement with the borrower in which the Company has the right, but not the obligation, to acquire a majority of the outstanding common stock of the borrower during the period beginning July 1, 2024 and ending August 31, 2024. The Company accounts for the loan agreement and option agreement as a single financial instrument (together, the “Investment Loan Receivable”). The Company recorded the Investment Loan Receivable at its fair value of $7,000 on the agreement date. As of June 30, 2024, the fair value of the Investment Loan Receivable was $7,083 and was included in prepaid expenses and other current assets in the unaudited condensed consolidated balance sheet.

With respect to its investment loan receivable, the Company held a variable interest in the borrower, which is a variable interest entity. After evaluation of the relationship between the Company and this variable interest entity, the Company determined not to consolidate this variable interest entity’s results of operations for the three and six months ended June 30, 2024. Significant judgments included the determination that the Company was not the primary beneficiary of the variable interest entity given the Company’s variable interests did not constitute a controlling financial interest.

The Company elected to account for this investment by utilizing the fair value option. The Company records investment loan receivables at their fair value on the agreement date. Each reporting period thereafter, these receivables are revalued and increases or decreases in their fair values are recorded as an adjustment to other income, net within the unaudited condensed consolidated statements of operations and comprehensive income (loss). The Company generally determines the fair value using the discounted cash flow method. The significant assumptions used to estimate the fair value include the interest rate, risk-free rate, expected repayment date, equity value, equity volatility, expected timing of exercise, and the credit spread assumption specific to the investment loan. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period.

Earnings Per Share [Abstract]

Net Income (Loss) Per Share

Net Income (Loss) Per Share

For the three and six months ended June 30, 2024, diluted net income per share was calculated by dividing net income attributable to Semrush Holdings, Inc. by the weighted-average number of shares of common stock outstanding during the period, including the dilutive impact of stock options and shares of common stock issuable upon the vesting of Restricted Stock Units (“RSUs”). The adjustment to net income attributable to Semrush Holdings, Inc. related to the Company’s redeemable noncontrolling interest is not material and did not impact net income per share for the three and six months ended June 30, 2024.

For the three and six months ended June 30, 2023, the net loss attributable to common stockholders is divided by the weighted-average number of shares of common stock outstanding during the period to calculate both basic and diluted earnings per share. The dilutive effect of common stock equivalents has been excluded from the calculation of diluted net loss per share for these periods as its effect would have been anti-dilutive due to the net losses incurred for the periods.

The following table presents a reconciliation of weighted-average shares outstanding used in the calculation of basic and diluted net income (loss) per share:

	Three Months Ended June 30,		Six Months Ended June 30,
	2024	2023	2024	2023
Weighted-average shares outstanding:
Weighted-average number of shares of common stock used in computing net income (loss) per share attributable to common stockholders—basic	145,678,323	142,239,140	145,121,951	141,946,425
Dilutive effect of share equivalents resulting from stock options	1,940,654	—	2,066,972	—
Dilutive effect of share equivalents resulting from restricted stock units	1,206,334	—	1,072,484	—
Weighted-average number of shares of common stock used in computing net income (loss) per share attributable to common stockholders—diluted	148,825,311	142,239,140	148,261,407	141,946,425

The following potentially dilutive common stock equivalents, including stock options and restricted stock units, have been excluded from the calculation of diluted weighted-average shares outstanding for the three and six months ended June 30, 2024 and 2023 because to do so would have been anti-dilutive for the periods presented:

	Three Months Ended June 30,		Six Months Ended June 30,
	2024	2023	2024	2023
Stock options outstanding	2,321,962	8,619,112	3,445,481	8,619,112

	3,252,011	11,402,894	4,888,318	11,402,894

For the three and six months ended June 30, 2024, 1,128,021 and 1,128,021 shares of Class A common stock potentially issuable under Performance Stock Unit (“PSU”) awards were excluded from the table above, respectively. For the three and six months ended June 30, 2023, 1,077,726 shares of Class A common stock potentially issuable under PSU awards were excluded from the table above, respectively. The performance-based conditions had not been met and were deemed improbable of achievement as of the reporting period end date.

Acquisitions

Brand 24

On April 29, 2024, the Company completed a stock purchase agreement to acquire approximately 58% of the voting equity interests in Brand 24 S.A. (“Brand 24”). The Company has accounted for this transaction as a business combination under the acquisition method. The purpose of the business combination was to expand our public relations business and customer base. The acquisition date fair value of the consideration transferred consisted of the following:

	Acquisition Date
Consideration transferred	Fair Value
Cash paid at close	$	10,650
Fair value of deferred purchase payments	2,878
Consideration transferred	$	13,528
Redeemable noncontrolling interest	9,846
Total purchase consideration	$	23,374

The Company determined that the fair value of the assets acquired and liabilities assumed was $23,374, including the fair value of the redeemable noncontrolling interest in Brand 24 of $9,846, which is reflected outside of the stockholders’ equity section of the unaudited condensed consolidated balance sheet as of June 30, 2024. The fair value of the redeemable noncontrolling interest on the closing date was estimated considering the implied enterprise value and the acquired percentage of Brand 24. The fair value of deferred purchase payments represents the fair value of two payments of $1,500 each, the first of which will be paid December 31, 2024 and is included within other current liabilities within the unaudited condensed consolidated balance sheet as of June 30, 2024. The second payment is due November 12, 2025 and is included in other long term liabilities within the unaudited condensed consolidated balance sheet as of June 30, 2024. The deferred purchase payments will accrue interest of 2.5% per year.

The table below summarizes the Company’s preliminary purchase price allocation. The allocation of the purchase price is preliminary as of June 30, 2024 as the Company continues to gather information supporting the acquired assets and liabilities to finalize the purchase price allocation.

	Purchase Price
Assets acquired	Allocation
Fair value of tangible assets:
Cash and cash equivalents	$	1,502
Accounts Receivable	139
Other assets	686
Identifiable intangible assets	9,350
Goodwill	15,846
Total assets acquired	$	27,523
Liabilities assumed
Deferred revenue, current	847
Deferred tax liabilities	1,411
Other liabilities	1,891
Total Liabilities Assumed	$	4,149
Fair value of assets acquired and liabilities assumed, net	$	23,374
Fair value of redeemable noncontrolling interest	$	9,846
Fair value of controlling interest acquired	$	13,528

The Company allocated $9,350 of the purchase price to identifiable intangible assets consisting of customer relationships, developed technology, and trade names, which it amortizes over the assets’ useful lives using a straight-line amortization method. The Company assigned useful lives to acquired customer relationships, developed technology, and trade names, of six years, five years, and five years, respectively. The Company used the multi-period excess earnings method to value the customer relationships. Customer relationships represent the underlying relationships with certain customers to provide ongoing services for products sold. To value the developed technology and trade names assets, the Company utilized the relief from royalty method. Trade names primarily relate to the Brand 24 brand. The significant assumptions used to estimate the value of the intangible assets included the discount rate, revenue growth rates, and customer attrition rates. After allocating the purchase price to identifiable assets acquired and liabilities assumed, the remaining purchase price was allocated to goodwill, which primarily relates to expected synergies from combining operations and is not deductible for tax purposes.

The Company recorded $225 and $389 in transaction costs related to the transaction during the three and six months ended June 30, 2024, respectively, which are included in the unaudited condensed consolidated statements of operations and comprehensive income (loss) in its income from continuing operations under the line item, General and administrative.

As of April 29, 2024, the results of Brand 24’s operations are included within the Company’s consolidated financial statements. This business combination did not have a material impact on the Company’s consolidated financial statements. Therefore, actual results of operations subsequent to the acquisition date and pro forma results of operations have not been presented.

In April 2024 the Company entered into award agreements with certain members of Brand 24 Management. These awards are accounted for as liability-classified awards under ASC 718, Compensation - Stock Compensation. The fair value of the awards were estimated using a Monte Carlo Simulation. The Company recorded $150 in post-acquisition compensation expense related to these awards during the three and six months ended June 30, 2024.

In May 2024, the Company announced a tender offer to purchase up to 944,616 shares of Brand 24 (the “Tender Offer”) at a price equal to PLN47.0 per share with an opening date for subscriptions of May

31, 2024 and a closing date for subscriptions of July 2, 2024. The Tender Offer was mandatory due to Polish Law and as a result has been accounted for as redeemable noncontrolling interest classified in temporary equity in the unaudited condensed consolidated balance sheet as of June 30, 2024. As a result of the Tender Offer, the fair value of the redeemable noncontrolling interest was adjusted to the redemption value equal to the Tender Offer price. The $978 difference between the acquisition date fair value of the redeemable noncontrolling interest and the Tender Offer price was recorded through additional paid-in capital in the unaudited condensed consolidated balance sheet as of June 30, 2024.

As of June 30, 2024, the Company received notice for the sale of 177,474 shares resulting in the reclassification of $2,021 in Tender Offer obligations from redeemable noncontrolling interest to other current liabilities.

Datos

On December 1, 2023, the Company completed a stock purchase agreement to acquire approximately 60% of the voting equity interests in Datos Inc. (“Datos”). The Company has accounted for this transaction as a business combination under the acquisition method. The primary purpose of this business combination is to acquire Datos’ valuable clickstream data software. The Company performed acquisition accounting as of December 1, 2023. The acquisition date fair value of the consideration transferred consisted of the following:

	Acquisition Date
Consideration transferred	Fair Value
Fair value of the January 2021 and February 2022 Convertible Notes	$	7,530
Cash paid at close	4,255
Other consideration	2,070
Total purchase consideration	$	13,855

The Company determined that the fair value of the assets acquired and liabilities assumed was $19,021, including the fair value of the noncontrolling interest in Datos of $5,166. The fair value of the noncontrolling interest is inclusive of the fair value of the acquired call option, which gives the Company the right, but not the obligation, to purchase the remaining shares in Datos during the period beginning January 1, 2026 and ending on January 1, 2027 (the “Call Option”). The Company estimated the fair value of the noncontrolling interest, inclusive of the Call Option, using an option pricing method (a special case of the income approach), considering the initial transaction price and based on Level 3 significant unobservable inputs such as the total equity value of Datos, forecasted revenues, volatility, and risk-adjusted discount rates. Other consideration includes the deferred purchase payments, the contingent payment, and additional consideration due to the seller. A payment of $501 was made during March 2024 related to other consideration. The remaining fair value of other consideration has been recorded to other current liabilities in the unaudited condensed consolidated balance sheet as of June 30, 2024.

The table below summarizes the Company’s purchase price allocation. The allocation of the purchase price is final as of June 30, 2024.

	Purchase Price

Fair value of tangible assets:
Cash and cash equivalents	$	549

Fair value of assets acquired and liabilities assumed, net	$	19,021
Fair value of noncontrolling interest, including call option	$	5,166
Fair value of controlling interest acquired	$	13,855

The Company recorded $0 and $100 in transaction costs related to the transaction during the three and six months ended June 30, 2024, respectively, which are included in the unaudited condensed consolidated statements of operations and comprehensive income (loss) in its income from continuing operations under the line item, General and administrative.

As of December 1, 2023, the results of Datos’ operations are included within the Company’s consolidated financial statements. This business combination did not have a material impact on the Company’s consolidated financial statements. Therefore, actual results of operations subsequent to the acquisition date and pro forma results of operations have not been presented.

Traffic Think Tank

On February 23, 2023, the Company completed a purchase agreement with Rank, LLC (“Traffic Think Tank”), acquiring certain intangible assets of Traffic Think Tank for total cash consideration of $1,800, of which $360 was paid during February 2024 (the “12-month holdback amount”) and $360 will be paid in 18 months (the “18-month holdback amount”). The remaining consideration was paid upon closing. The 18-month holdback amount is recorded in other current liabilities in the unaudited condensed consolidated balance sheet as of June 30, 2024. The primary purpose of the acquisition was to acquire valuable brand and content related to Traffic Think Tank’s SEO community and courses.

This business combination did not have a material impact on the Company’s unaudited condensed consolidated financial statements. Therefore, actual results of operations subsequent to the acquisition date and pro forma results of operations have not been presented.

Income Taxes

Income Taxes

The Company is subject to income taxes in U.S. federal, state, and foreign jurisdictions. For the three and six months ended June 30, 2024, the Company recorded provisions for income taxes of $4,649 and $7,753, respectively. For the three and six months ended June 30, 2023, the Company recorded provisions for income taxes of $869 and $1,666, respectively. The Company’s effective tax rate for the six months ended June 30, 2024 differs from the U.S. statutory rate due primarily to the impact of earnings in foreign jurisdictions and the impact of the requirement to capitalize and amortize certain research and development costs which results in a current U.S. tax provision but no deferred tax benefit as a result of the valuation allowance maintained against our net deferred tax assets. The Company’s income tax expense for the three and six months ended June 30, 2023, respectively, primarily relates to income earned in certain foreign jurisdictions.

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. These differences are measured using the enacted statutory tax rates that are expected to be in effect for the years in which differences are expected to reverse. On a periodic basis, the Company reassesses any valuation allowances it maintains on its deferred tax assets, weighing positive and negative evidence to assess the recoverability of the deferred tax assets. The Company maintains a valuation allowance on its net deferred tax assets.

The Company recorded stock-based compensation expense of $7,166 and $12,281 during the three and six months ended June 30, 2024, respectively, and recorded $3,765 and $6,561 during the three and six months ended June 30, 2023, respectively. The following table shows stock-based compensation expense by where the stock-based compensation expense is recorded in the Company’s unaudited condensed consolidated statement of operations:

	Three Months Ended June 30,				Six Months Ended June 30,

Cost of revenue	$	59	$	32	$	98	$	49

Total stock-based compensation	$	7,166	$	3,765	$	12,281	$	6,561

As of June 30, 2024, there was $14,052 of unrecognized compensation cost related to unvested common stock option arrangements, which is expected to be recognized over a weighted-average period of 2.43 years. As of June 30, 2024, there was $46,162 of unrecognized compensation cost related to unvested restricted stock unit awards, which is expected to be recognized over a weighted-average period of 2.57 years. As of June 30, 2024, there was $22,435 of unrecognized compensation cost related to unvested performance stock unit awards, which is expected to be recognized over a weighted-average period of 3.29 years.

The fair value of each option award was estimated on the date of grant using the Black-Scholes option-pricing model. As there was no public market for its common stock prior to March 25, 2021, which was the first day of trading, and as the trading history of the Company’s common stock is limited, the Company determined the expected volatility for options granted based on an analysis of reported data for a peer group of companies that issued options with substantially similar terms. The expected volatility of options granted has been determined using an average of the historical volatility measures of this peer group of companies. The expected life of options granted to employees was calculated using the simplified method, which represents the average of the contractual term of the option and the weighted-average vesting period of the option. The Company uses the simplified method because it does not have sufficient historical option exercise data to provide a reasonable basis upon which to estimate expected term. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected life of the share option. The Company has not paid, nor anticipates paying, cash dividends on its ordinary shares; therefore, the expected dividend yield is assumed to be zero.

The weighted-average assumptions utilized to determine the fair value of options granted to employees are presented in the following table:

	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Expected volatility	—	%	63.0	%	61.8	%	63.2	%
Weighted-average risk-free interest rate	—	%	3.48	%	4.28	%	3.70	%
Expected dividend yield	—		—		—		—
Expected life – in years	—		6		6		6

A summary of the Company’s option activity as of June 30, 2024, and changes during the six months then ended are as follows:

	Number of Options	Weighted-Average Exercise Price (per share)		Weighted-Average Remaining Contractual Term (in years)
Outstanding at January 1, 2024	7,175,494	$	7.02	7.78
Granted	15,888	12.62
Exercised	(1,190,759)	2.56

Options exercisable at June 30, 2024	3,217,588	6.10		6.74

The Company did not grant option awards during the three months ended June 30, 2024. The weighted-average grant-date fair value of options granted during the six months ended June 30, 2024 was $7.71 per share. The weighted-average grant-date fair value of options granted during the three and six months ended June 30, 2023 was $5.84 and $5.56 per share, respectively. Tax benefits of $554 and $699 were realized from options during the three and six months ended June 30, 2024, respectively. Tax benefits of $(10) and $43 were realized from options during the three and six months ended June 30, 2023, respectively.

Litigation

From time to time the Company may become involved in legal proceedings or be subject to claims arising in the ordinary course of its business. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on its business, operating results, financial condition or

cash flows. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

Indemnification

The Company typically enters into indemnification agreements with customers in the ordinary course of business. Pursuant to these agreements, the Company indemnifies and agrees to reimburse the indemnified party for losses suffered or incurred as a result of claims of intellectual property infringement. These indemnification agreements are provisions of the applicable customer agreement. Based on when clients first sign an agreement for the Company’s service, the maximum potential amount of future payments the Company could be required to make under certain of these indemnification agreements is unlimited. Based on historical experience and information known as of June 30, 2024, the Company has not incurred any costs for the above guarantees and indemnities.

In certain circumstances, the Company warrants that its services will perform in all material respects in accordance with its standard published specification documentation in effect at the time of delivery of the services to the customer for the term of the agreement. To date, the Company has not incurred significant expense under its warranties and, as a result, the Company believes the estimated fair value of these agreements is immaterial.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2024

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

The unaudited condensed consolidated interim financial statements have been prepared on the same basis as the audited annual consolidated financial statements as of and for the year ended December 31, 2023, and, in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of June 30, 2024, and for the three and six months ended June 30, 2024 and 2023. The consolidated balance sheet as of December 31, 2023 included herein was derived from the audited consolidated financial statements as of that date.

The results for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024, any other interim periods, or any future year or period.

The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 7, 2024.

The accompanying unaudited condensed consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to the unaudited condensed consolidated financial statements. As of June 30, 2024, there have been no material changes in the Company's significant accounting policies from those that were disclosed in the Annual Report on Form 10-K, except as discussed below.

Principles of Consolidation

Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, and subsidiaries in which it holds a controlling interest. All intercompany transactions and balances have been eliminated in consolidation. Ownership interests in subsidiaries represented by other parties that do not control the entity are presented in the consolidated financial statements as activities and balances attributable to noncontrolling interests.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Significant estimates relied upon in preparing these unaudited condensed consolidated financial statements include, but are not limited to, revenue recognition, expected future cash flows used to evaluate the recoverability of long-lived assets, contingent liabilities, expensing and capitalization of research and development costs for internal-use software, the average period of benefit associated with costs capitalized to obtain revenue contracts, the determination of the fair value of stock-based awards issued, stock-based compensation expense, the determination of the estimated fair value of loan receivables and convertible notes held by the Company, the valuations of the intangible assets acquired through acquisitions, the estimation of the Company’s incremental borrowing rate, and the recoverability of the Company’s net deferred tax assets and related valuation allowance.

Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made.

Subsequent Events Considerations

Subsequent Events Considerations

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the unaudited condensed consolidated financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. See Note 18 for additional information regarding the Company’s subsequent events.

Revenue Recognition

Revenue Recognition

The Company primarily derives revenue from subscriptions to the Company’s SaaS services and related customer support. For the three and six months ended June 30, 2024 and 2023, subscription revenue accounted for nearly all of the Company’s revenue. Revenue related to other revenue was not material for the three and six months ended June 30, 2024 and 2023.

The Company offers subscriptions to its platform primarily on a monthly or annual basis. The Company sells its products and services primarily through a self-service model and also directly through its sales force. The Company’s subscription arrangements provide customers the right to access the Company’s hosted software applications. Customers do not have the right to take possession of the Company’s software during the hosting arrangement. Subscriptions are generally non-cancellable during the contractual subscription term; however, subscription contracts contain a right to a refund if requested within seven days of purchase.

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration it expects to receive in exchange for those products or services. There were no changes to the Company’s revenue recognition policies since the filing of its Annual Report on Form 10-K with the SEC on March 7, 2024.

Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. The Company primarily invoices and collects payments from customers for its services in advance on a monthly or annual basis.

Deferred revenue represents amounts billed for which revenue has not yet been recognized. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as deferred revenue, and the remaining portion is recorded as deferred revenue, net of current portion. Deferred revenue increased by $8,185 as of June 30, 2024 compared to December 31, 2023. During the three and six months ended June 30, 2024, $32,354 and $39,426 of revenue was recognized that was included in deferred revenue at the beginning of each respective period. During the three and six months ended June 30, 2023, $27,865 and $37,831 of revenue was recognized that was included in deferred revenue at the beginning of each respective period.

The Company has elected to exclude amounts charged to customers for sales tax from the transaction price. Accordingly, revenue is presented net of any sales tax collected from customers.

Transaction Price Allocated to Future Performance Obligations

ASC 606 requires that the Company disclose the aggregate amount of the transaction price that is allocated to performance obligations that have not yet been satisfied as of the balance sheet dates reported.

For contracts with an original expected duration greater than one year, the aggregate amount of the transaction price allocated to the performance obligations that were unsatisfied as of June 30, 2024 was $1,207, of which the Company expects to recognize $970 over the next 12 months.

For contracts with an original expected duration of one year or less, the Company has applied the practical expedient available under ASC 606 to not disclose the amount of transaction price allocated to unsatisfied performance obligations as of June 30, 2024. For performance obligations not satisfied as of June 30, 2024, and to which this expedient applies, the nature of the performance obligations is consistent with performance obligations satisfied as of December 31, 2023.

Costs to Obtain a Contract

The incremental direct costs of obtaining a contract, which primarily consist of sales commissions paid for new subscription contracts, are deferred and recorded as deferred contract costs in the unaudited condensed consolidated balance sheets and are amortized over a period of approximately 24 months on a systematic basis, consistent with the pattern of transfer of the goods or services to which the asset relates. The 24-month period represents the estimated benefit period of the customer relationship and has been determined by taking into consideration the type of product sold, the commitment term of the customer contract, the nature of the Company’s technology development life-cycle, and an estimated customer relationship period based on historical experience and future expectations. Deferred contract costs that will be recorded as expense during the succeeding 12-month period are recorded as deferred contract costs, current portion, and the remaining portion is recorded as deferred contract costs, net of current portion. Amortization of deferred contract costs is included in sales and marketing expense in the accompanying unaudited condensed consolidated statements of operations and comprehensive income (loss).

Concentrations of Credit Risk and Significant Customers

Concentrations of Credit Risk and Significant Customers

The Company has no off-balance sheet risk, such as foreign exchange contracts, option contracts, or other hedging arrangements. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. 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.

Credit risk with respect to accounts receivable is dispersed due to the large number of customers of the Company. The Company routinely assesses the creditworthiness of its customers and generally does not require its customers to provide collateral or other security to support accounts receivable. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. 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.

Disclosure of Fair Value of Financial Instruments

Disclosure of Fair Value of Financial Instruments

The Company’s financial instruments include cash, cash equivalents, investments, accounts receivable, loan receivables, accounts payable, and accrued expenses. The Company’s investments are classified as available-for-sale and reported at fair value in accordance with the market approach utilizing quoted prices that were directly or indirectly observable. The Company has elected the fair value option in respect to the accounting for its loan receivable investment, resulting in increases and decreases in the fair value of such investments being recorded to other income, net for each reporting period. The carrying

amount of the remainder of the Company’s financial instruments approximated their fair values as of June 30, 2024 and December 31, 2023, due to the short-term nature of these instruments.

The Company has evaluated the estimated fair value of financial instruments using available market information. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts.

Cash equivalents include money market funds with original maturities of 90 days or less from the date of purchase. The fair value measurement of these assets is based on quoted market prices in active markets for identical assets and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 1 in the fair value hierarchy. The Company’s investments primarily consist of U.S. treasury securities. The fair value measurement of these assets is based on significant other observable inputs and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 2 in the fair value hierarchy.

As of June 30, 2024, the Company measured its investment loan receivables (see Note 7) and its contingent consideration associated with the acquisition of Datos Inc. on a recurring basis using significant unobservable inputs (Level 3). As of December 31, 2023, the Company measured its contingent consideration associated with the acquisition of Datos Inc. on a recurring basis using significant unobservable inputs (Level 3).

Foreign Currency Translation

Foreign Currency Translation

The Company operates in a multi-currency environment having transactions in such currencies as the U.S. dollar, zloty, Czech koruna, euro, and others. The reporting currency of the Company is the U.S. dollar.

Comprehensive Income (Loss)

Comprehensive income (loss)

Comprehensive income (loss) is comprised of two components: net income (loss) and other comprehensive income (loss), which includes other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. For the three and six months ended June 30, 2024 and 2023, comprehensive income (loss) consists of net income (loss), the change in the cumulative foreign currency translation adjustment, and unrealized loss on investments. The tax effect of the cumulative foreign currency translation adjustment and unrealized loss on investments was not significant for the three and six months ended June 30, 2024 and 2023.

Recent Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. 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 evaluating the impact of adopting ASU 2023-07 on its consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740)-Improvements to Income Tax Disclosures (“ASU 2023-09”).
