**SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS** 

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements made in this Quarterly Report on Form 10-Q that are not statements of historical fact, including statements about our beliefs and expectations and regarding future events or our future results of operations, financial condition, business, strategies, financial needs, the plans and objectives of management, and our stock repurchase program are forward-looking statements and should be evaluated as such. These statements often include words such as "anticipate," "believe," "expect," "suggests," "plans," "intend," "estimates," "targets," "projects," "should," "could," "would," "may," "will," "forecast," and other similar expressions or the negatives of those terms. We base these forward-looking statements on our current expectations, plans, and assumptions that we have made in light of our experience in the industry, as well as our perceptions of historical trends, current conditions, expected future developments and other factors we believe are appropriate under the circumstances at such time. As you read and consider this Quarterly Report on Form 10-Q, you should understand that these statements are not guarantees of future performance or results. The forward-looking statements are subject to and involve risks, uncertainties and assumptions, and you should not place undue reliance on these forward-looking statements. Although we believe that these forward-looking statements are based on reasonable assumptions at the time they are made, you should be aware that many factors could affect our actual results or results of operations and could cause actual results to differ materially from those expressed in the forward-looking statements. Important factors that may materially affect such forward-looking statements include, but are not limited to:

● our ability to maintain and grow revenue from existing customers and new customers, and expand their usage of our solutions;

● our ability to maintain and expand our strategic relationships with third parties;

● our ability to adapt to technological change and successfully introduce new solutions or provide updates to existing solutions;

● risks related to failures in information technology or infrastructure;

● risks related to our reliance on government infrastructure to support our e-invoicing services;

● challenges in using and managing use of Artificial Intelligence ("AI") in our business;

● incorrect or improper implementation, integration or use of our solutions;

● failure to attract and retain qualified technical and tax-content personnel;

● competitive pressures from other tax software and service providers and challenges of convincing businesses using native enterprise resource planning functions to switch to our software;

● our ability to accurately forecast our revenue and other future results of operations based on recent success;

● our ability to offer specific software deployment methods based on changes to customers' and partners' software systems;

● our ability to continue making significant investments in software development and equipment;

● our ability to sustain and expand revenues, maintain profitability, and to effectively manage our anticipated growth;

● our ability to successfully diversify our solutions by developing or introducing new solutions or acquiring and integrating additional businesses, products, services, or content;

● our ability to successfully integrate acquired businesses and to realize the anticipated benefits of such acquisitions;

● risks related to the fluctuations in our results of operations;

● risks related to our expanding international operations;

● our exposure to liability from errors, delays, fraud or system failures, which may not be covered by insurance;

[**Table of Contents**](#TOC)

● our ability to adapt to organizational changes and effectively implement strategic initiatives;

● risks related to our determinations of customers' transaction tax and tax payments;

● risks related to changes in tax laws and regulations or their interpretation or enforcement;

● our ability to manage cybersecurity and data privacy risks;

● our involvement in material legal proceedings and audits;

● risks related to undetected errors, bugs or defects in our software;

● risks related to utilization of open-source software, business processes and information systems;

● our ability to effectively protect, maintain, and enhance our brand;

● changes in application, scope, interpretation or enforcement of laws and regulations;

● business disruptions related to natural disasters, epidemic outbreaks, including a global endemic or pandemic, terrorist acts, political events, or other events outside of our control;

● our ability to comply with anti-corruption, anti-bribery, and similar laws;

● our ability to protect our intellectual property;

● changes in interest rates, security ratings and market perceptions of the industry in which we operate, or our ability to obtain capital on commercially reasonable terms or at all;

● our ability to maintain an effective system of disclosure controls and internal control over financial reporting, or ability to remediate any material weakness in our internal controls;

● risks related to our Class A common stock and controlled company status;

● risks related to our Repurchase Program (as defined in the notes to the financial statements);

● risks related to our indebtedness and adherence to the covenants under our debt instruments;

● the effects of the Capped Call Transactions (as defined in the notes to the financial statements) and the actions of the Option Counterparties (as defined in the notes to the financial statements) and/or their respective affiliates;

● risks related to our Value Creation Plan;

● any statements of belief and any statements of assumptions underlying any of the foregoing; and

● other factors beyond our control.

[**Table of Contents**](#TOC)

The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance, including factors and risks included in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the Securities and Exchange Commission (the "SEC") on February 24, 2026 (the "2025 Annual Report"). Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time, and it is not possible for us to identify all such risk factors, nor can we assess the impact of all such risk factors on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, you should not place undue reliance on our forward-looking statements, and you should not rely on forward-looking statements as predictions of future events. 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 speak only as of the date of this report. We undertake no obligation to update any forward-looking statements made in this report to reflect events or circumstances after the date of this report or to reflect new information or the occurrence of unanticipated events, except as required by law. If we update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES** 

#### Nature of Business
Vertex, Inc. ("Vertex") and its consolidated subsidiaries (collectively, the "Company") operate as solutions providers of state, local, and value added tax calculation, compliance, and analytics, offering software products that are sold through software license and software as a service ("cloud") subscriptions. The Company also provides implementation and training services in connection with its software license and cloud subscriptions, transaction tax returns outsourcing, and other tax-related services. The Company sells to customers located throughout the United States ("U.S.") and internationally.

**Basis of Consolidation**

The condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP") and include the accounts of the Company. All intercompany transactions have been eliminated in consolidation.

On March 2, 2026, the Company completed its acquisition of Brinta (defined in Note 3). The acquisition was accounted for as a business combination. Upon its acquisition, Brinta became a wholly owned subsidiary of the Company, and its operations have been included in the Company's condensed consolidated financial statements commencing on the Acquisition Date (as defined below).

**Unaudited Interim Financial Information**

The accompanying unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") for interim financial information and include the accounts of the Company. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes for the year ended December 31, 2025 included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 (the "2025 Annual Report") filed with the SEC on February 24, 2026. The condensed consolidated balance sheet as of December 31, 2025 has been derived from audited financial statements included in the 2025 Annual Report. The accompanying interim condensed consolidated balance sheet as of March 31, 2026, the interim condensed consolidated statements of comprehensive income and changes in stockholders' equity for the three months ended March 31, 2026 and 2025, and the interim condensed consolidated statements of cash flows for the three months ended March 31, 2026 and 2025 are unaudited. The unaudited interim condensed consolidated financial statements have been prepared on a basis consistent with that used to prepare the annual audited consolidated financial statements and include, in the opinion of management, all adjustments, consisting of normal and recurring items necessary for the fair presentation of the condensed consolidated financial statements. The operating results for the three months ended March 31, 2026 are not necessarily indicative of the results expected for the full year ending December 31, 2026.

**Use of Estimates**

The preparation of condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenues, and expenses during the reporting period. Significant estimates used in preparing these condensed consolidated financial statements include: (i) the estimated allowance for subscription cancellations; (ii) expected credit losses associated with the allowance for doubtful accounts; (iii) allowance for credit losses on available-for-sale debt securities; (iv) the reserve for self-insurance; (v) assumptions related to achievement of technological feasibility for software developed for sale; (vi) product life cycles; (vii) estimated

useful lives and potential impairment of long-lived assets, intangible assets, and capitalized cloud computing arrangement software implementation costs; (viii) potential impairment of goodwill; (ix) determination of the fair value of tangible and intangible assets acquired, liabilities assumed, and consideration transferred in acquisitions; (x) amortization period of deferred commissions; (xi) Black-Scholes-Merton option pricing model ("Black-Scholes model") input assumptions used to determine the fair value of certain stock-based compensation awards and Employee Stock Purchase Plan ("ESPP") purchase rights; (xii) measurement of future purchase commitment, fair value of contingent consideration liabilities related to cash and stock earn-out payments, contingent consideration and deferred purchase consideration liabilities associated with acquisitions; (xiii) measurements of long-term investment and warrant rights; and (xiv) the potential outcome of future tax consequences of events that have been recognized in the condensed consolidated financial statements or tax returns. Actual results may differ from these estimates.

Cloud computing software implementation costs incurred in hosting arrangements are capitalized and included as a component of prepaid expenses and other current assets, or other assets, once available for their intended use. These costs are amortized using the straight-line method over their respective contract service periods, including periods covered by an option to extend, ranging from two to five years. Amortization expense for capitalized cloud computing implementation costs for the three months ended March 31, 2026 and 2025 were $1,037 and $1,006, respectively, and are included in general and administrative expense in the condensed consolidated statements of comprehensive income.

**Recently Issued Accounting Pronouncements**

 *Interim Reporting (Topic 270): Narrow-Scope Improvements*

In December 2025, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. The standard provides clarifications intended to improve the consistency and usability of interim disclosure requirements, including a comprehensive listing of required interim disclosures and a new disclosure principle for reporting material events occurring after the most recent annual period. The standard does not change the fundamental nature of interim reporting. The standard is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years. The Company is currently evaluating the impact of the standard on its interim reporting processes, including updates to disclosure controls, and interim footnote structure. However, the Company does not expect the adoption of the standard to have a material impact on its consolidated financial statements.

*Targeted Improvements to the Accounting for Internal-Use Software* 

In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. ASU 2025-06 replaces the existing stage based capitalization model with a principles-based approach. Under the new guidance, software development costs are capitalized only when (i) management has authorized and committed to funding the software project, and (ii) it is probable that the project will be completed and the software will be used to perform its intended function. The standard also consolidates guidance for website development costs from Subtopic 350-50 into Subtopic 350-40 and introduces enhanced disclosure requirements related to capitalized software costs. The standard is effective for annual reporting periods beginning after December 15, 2027, including interim reporting periods within those fiscal years. The standard can be adopted retrospectively, prospectively or on a modified prospective basis, and early adoption is permitted as of the beginning of an annual reporting period, provided that the financial statements for that period have not yet been issued or made available for issuance. The Company is currently evaluating the impact of the standard on its consolidated financial statements and related disclosures and will determine the appropriate transition method prior to adoption.

*Disaggregation of Income Statement Expenses* 

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. Entities will be required to provide disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements for both interim and annual reporting periods. The standard does not change the expense captions that an entity presents on the face of the income statement. The standard will be effective for annual reporting periods beginning after December 15, 2026, and for interim reporting periods for annual reporting periods beginning after December 15, 2027, with early adoption permitted. Entities are required to adopt the standard prospectively; however, entities are permitted to apply the amendments retrospectively to any or all prior periods presented in the financial statements. The Company is continuing to assess the potential impacts of the standard but does not expect this standard to have a material effect on its financial statements, other than the required changes to the disclosures.

2.&nbsp;&nbsp;&nbsp;&nbsp; REVENUE RECOGNITION

#### Disaggregation of revenue
The table reflects revenue by major source for the following periods:

---

| | | |
|:---|:---|:---|
|  | **Three months ended March 31,**  | **Three months ended March 31,**  |
|  | **2026** | **2025** |
|  | **(unaudited)** | **(unaudited)** |
| Software subscriptions: |  |  |
| &nbsp;&nbsp;Software licenses | $70376 | $70611 |
| &nbsp;&nbsp;Cloud subscriptions | 96770 | 80150 |
| Software subscriptions | 167146 | 150761 |
| Services | 29500 | 26301 |
| &nbsp;&nbsp;Total revenues | $196646 | $177062 |

---

*Contract balances*

Timing of revenue recognition may differ from the timing of invoicing customers. A receivable is recorded in the condensed consolidated balance sheets when customers are billed related to revenue to be collected and recognized for subscription agreements as there is an unconditional right to invoice and receive payment in the future related to these subscriptions. A receivable and related revenue may also be recorded in advance of billings to the extent services have been performed and the Company has a right under the contract to bill and collect for such performance. Subscription-based customers are generally invoiced annually at the beginning of each annual subscription period. Accounts receivable is presented net of an allowance for potentially uncollectible accounts and estimated cancellations of software license and cloud-based subscriptions (the "allowance") of $13,225 and $11,466 at March 31, 2026 and December 31, 2025, respectively. The allowance for potentially uncollectible accounts represents future expected credit losses over the life of the receivables based on past experience, current information and forward-looking economic considerations.

The beginning and ending balances of accounts receivable, net of allowance, are as follows:

---

| | | |
|:---|:---|:---|
|  | **For the three months ended March 31, 2026** | **For the year ended December 31, 2025** |
|  | **(unaudited)** |  |
| Balance, beginning of period | $183446 | $164432 |
| Balance, end of period | 158998 | 183446 |
| &nbsp;&nbsp;Increase (decrease) | $(24448) | $19014 |

---

A contract liability is recorded as deferred revenue on the condensed consolidated balance sheets when customers are billed in advance of performance obligations being satisfied, and revenue is recognized after invoicing ratably over the subscription period. Deferred revenue is included net of a related deferred allowance for subscription cancellations (the "deferred allowance") of $4,943 and $4,120 at March 31, 2026 and December 31, 2025, respectively. The deferred allowance represents the portion of the allowance for subscription cancellations associated with deferred revenue.

The beginning and ending balances of and changes to the allowance and the deferred allowance are as follows:

#### Contract costs
Deferred sales commissions earned by the Company's sales force and certain sales incentive programs and vendor referral agreements are considered incremental and recoverable costs of obtaining a contract with a customer. An asset is recognized for these incremental contract costs and included as deferred commissions in the condensed consolidated balance sheets. These contract costs are amortized on a straight-line basis over a period consistent with the transfer of the associated product and services to the customer, which is generally one to three years. Amortization of these costs are included in selling and marketing expense in the condensed consolidated statements of comprehensive income. The Company periodically reviews these contract assets to determine whether events or changes in circumstances have occurred that could impact the period of benefit of these assets. There were no impairment losses recorded for the periods presented.

The changes to contract cost balances as of and for the following periods are:

3. ACQUISITIONS

On March 2, 2026 (the "Acquisition Date"), the Company completed its acquisition of 100% of the equity interests of Finta Inc. and its subsidiaries (collectively, "Brinta" or the "Acquisition"). Headquartered in Uruguay, Brinta is a Latin American provider of business-to-business integration services, specializing in indirect tax calculation, tax filing, and e-invoicing. The Company plans to fully integrate Brinta, leveraging its e-invoicing capabilities to immediately expand the Company's coverage across the Latin American region.

**Purchase Consideration**

Total purchase consideration for the Acquisition was $21,968 net of $40 cash acquired, which included $10,089 for the settlement of pre-existing debt/borrowings.

**Additional Consideration** 

*Stock Consideration*

In connection with the Acquisition, the Company granted the sellers 497 shares of its Class A common stock (the "Stock Consideration") in the form of restricted stock awards ("RSAs") with an aggregate fair value of $8,000 based on the average closing share price of the Company's Class A common stock for the 30 consecutive trading days ending one business day prior to the Acquisition Date. The RSAs vest ratably over a four-year period (25% vesting annually), conditioned on the continued employment of the sellers during that period. The Stock Consideration is accounted for as post-combination compensation cost and will be recognized as stock-based compensation expense over the applicable service period. For further information on these RSAs, see Note 11, "Stock-Based Award Plans."

*Additional Cash Consideration* 

In connection with the Acquisition, the Company entered into arrangements providing for aggregate additional cash consideration payments of $10,000 to the sellers (the "Additional Cash Consideration"), consisting of two installment payments of $5,000, payable on each of the first and second anniversaries of the Acquisition Date. Continued service to the Company is a requirement for the sellers to receive the additional cash consideration payments; however, in the event a seller is terminated without cause, the remaining payments remain payable on the original scheduled payment dates. These payments are accounted for as post-combination compensation liabilities and will be recognized as compensation expense over the applicable service period.

**Fair Value of Assets Acquired and Liabilities Assumed** 

The purchase price was allocated to the net assets acquired based on the Company's determination of their estimated fair values using available information as of the Acquisition Date. The excess of purchase consideration over the net assets acquired is recorded as goodwill, which primarily reflects the existence of intangible assets not recognized under U.S. GAAP such as the value of expected future synergies, the value of the assembled workforce and other market factors. The preliminary values recorded, which are reflected in the table below, will be adjusted during the measurement period as more detailed analyses are performed and further information becomes available regarding the fair values of these amounts on the Acquisition Date.

---

Any subsequent adjustments to the preliminary values not associated with determination of their fair values on the Acquisition Date will be recorded in the consolidated statements of comprehensive income (loss) in the period in which the adjustment is identified.

Total transaction costs associated with the Acquisition were $690 for the three months ended March 31, 2026 and are recorded in other operating expense (income), net in the condensed consolidated statements of comprehensive income (loss).

In connection with the August 2024 acquisition of ecosio GmbH ("ecosio"), the sellers are entitled to three annual earn-outs in the form of cash, with an aggregate of up to $94,355 (the "Cash Earn-outs"), and stock, with an aggregate value of up to $35,000 (the "Stock Earn-outs," and together with the Cash Earn-outs, the "Earn-outs"), assuming maximum payouts. The Earn-outs are based on ecosio's achievement of certain monthly software revenue targets over a three-year period, measured over an aggregate of 12 months and paid within 90 days after the relevant measurement period. At the acquisition date, the fair value of the Cash Earn-outs and Stock Earn-outs were $71,000 and $34,000, respectively. The fair value of the Cash Earn-out and the Stock Earn-out were measured on the acquisition date using a Monte Carlo simulation in a risk-neutral framework, calibrated to management's revenue forecasts. Additional information on the Cash Earn-outs and the Stock Earn-outs is presented in the following table:

Actual payouts are further adjusted depending on ecosio's software revenue attainment for each of the measurement periods. In the event that actual software revenues exceed 100% of the target, additional payments may be made up to a maximum of 122.5% of the annual target. If actual software revenues are below 85% of the target, no payouts are made for that measurement period. The Stock Earn-outs are paid in shares of the Company's Class A common stock.

The Cash Earn-outs and Stock Earn-outs are recorded at fair value in the condensed consolidated balance sheets as follows:

These Earn-outs represent recurring fair value measurements with significant unobservable inputs, which management considers to be Level 3 measurements under the fair value hierarchy. The final payments may be adjusted depending on the actual amount, above or below the target. The Earn-outs will be revalued and adjusted quarterly until the end of the Earn-out period, and any fair value adjustments will be recorded in the other operating expense (income), net line of the condensed consolidated statement of income (loss).

**Long-Term Investment** 

In April 2025, the Company entered into a Preferred Stock Purchase Agreement (the "Purchase Agreement") with Kintsugi AI, Inc. ("Kintsugi"), a San Francisco-based, AI startup focused on automating sales tax compliance for small and mid-size businesses (the "Kintsugi Investment").

Pursuant to the Purchase Agreement, the Company purchased 1,568 preferred shares (the "Preferred Stock") for aggregate consideration of approximately $15,000 (the "Purchase Price"), representing approximately 10% of the fully diluted shares outstanding of Kintsugi on an "as converted" basis, and received a warrant to purchase 320 shares of Kintsugi's Class A common stock at a price of $0.01 per share (the "Warrant"). The fair value of the Warrant was determined to be nil and therefore the Company allocated the full Purchase Price to the value of the Preferred Stock.

The Company classified the Preferred Stock as an equity security under ASC 321, Investments – Equity Securities. As Kintsugi is a privately held company without a readily determinable fair value, the Preferred Stock qualifies for the measurement alternative under ASC 321 and is measured at cost, less impairment, subject to upward and downward adjustments resulting from observable price changes for identical or similar investments of the same issuer. These adjustments require quantitative assessments of the fair value, which may require the use of unobservable inputs, which management considers to be Level 3 measurements under the fair value hierarchy. The Company performs a qualitative assessment each reporting period to identify indicators of impairment. No observable price change or impairment adjustments have been recorded for either the three months ended March 31, 2026 or 2025. The $15,000 carrying value of the Kintsugi Investment is presented in the long-term investment line in the condensed consolidated balance sheets.

**Assets and Liabilities for Which Fair Value is Only Disclosed**

The carrying amounts of cash and cash equivalents and the carrying amount of funds held for customers were the same as their respective fair values and are considered Level 1 measurements.

The carrying amount of the Company's bank debt approximates fair value as the variable rates on the debt approximate those commercially available in the market and is considered a Level 3 measurement.

**Non-recurring Fair Value Measurements** 

The Brinta acquisition on March 2, 2026, and the ecosio acquisition on August 30, 2024, were accounted for as business combinations and the total purchase price for each acquisition was allocated to the net assets acquired and liabilities assumed based on their estimated fair values.

**Derivative Instruments** 

The Company may periodically enter into derivative contracts to reduce its exposure to foreign currency exchange rates. Historically, the Company has not designated derivative contracts as hedges. Such derivative contracts are typically designed to manage specific risks according to the Company's strategies, which may change from time to time.

**Convertible Senior Notes**

As of March 31, 2026 and December 31, 2025, the fair value of the Notes (as defined in Note 8) was $299,595 and $327,043, respectively. The fair value was determined based on the quoted price of the Notes in an over-the-counter market on the last trading day of the reporting period and has been classified as Level 2 in the fair value hierarchy. For further information on the Notes, refer to Note 8, "Debt".

*The Repurchase Program*

On October 30, 2025, the board of directors (the "Board") authorized a stock repurchase program for up to $150,000 of the Company's outstanding shares of Class A common stock (the "Repurchase Program"). Under the Repurchase Program, share repurchases may be made from time to time in one or more open market or privately negotiated transactions, and/or through other legally permissible means in accordance with applicable rules and regulations promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The timing and amount of any shares repurchased will be determined by the Company's management based on its evaluation of market conditions and other factors. Repurchases may also be made under a Rule 10b5-1 plan, which would permit shares to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. Any repurchased shares will be available for use in connection with the Company's stock plans and for other corporate purposes. The Repurchase Program has no termination date and may be modified, suspended or discontinued at any time.

The Board intends all options granted to be exercisable at a price per share not less than the per share fair market value of the Company's Class A common stock underlying the options on the date of grant. Compensation expense for option awards are measured based on the grant date fair value of the awards and recognized in the condensed consolidated statements of comprehensive income (loss) over the period during which the participant is required to perform the requisite services. The vesting period is generally one to four years. The grant date fair value of options is estimated using the Black-Scholes model.

There were no options issued under the 2020 Plan during the three months ended March 31, 2026 or 2025. At March 31, 2026, all compensation expense associated with the options was fully recognized.

*Restricted Stock Units*

The following table summarizes RSU activity for the three months ended March 31, 2026:

---

| | | |
|:---|:---|:---|
|  | <br>**Units** | **Weighted**<br>**Average**<br>**Grant Date Fair**<br>**Value Per Share** |
|  | **(unaudited)** | **(unaudited)** |

| &nbsp;&nbsp;Forfeited | (118) | 22.15 |
| Outstanding at March 31, 2026 | 7532 | $19.51 |

---

Stock-based compensation cost for RSUs is measured based on the fair value of the Company's underlying common stock on the date of grant and is recognized on a straight-line basis in the condensed consolidated statements of comprehensive income (loss) over the period during which the participant is required to perform services in exchange for the award, which is generally one to four years. Vested RSUs are settled by issuing Class A common stock or the equivalent value in cash at the Board's discretion. At March 31, 2026, $116,101 of unrecognized compensation expense for RSUs is expected to be recognized over a weighted average period of approximately 3.0 years.

*Restricted Stock Awards*

The following table summarizes Restricted Stock Awards ("RSAs") activity for the three months ended March 31, 2026:

---

| | | |
|:---|:---|:---|
|  | <br>**Units** | **Weighted**<br>**Average**<br>**Grant Date Fair**<br>**Value Per Share** |

| &nbsp;&nbsp;Granted  | 497 | 14.40 |
| Outstanding at March 31, 2026 | 534 | $16.02 |

---

Stock-based compensation cost for RSAs is measured based on the fair value of the Company's underlying common stock on the date of grant and is recognized on a straight-line basis in the condensed consolidated statements of comprehensive income (loss) over the period during which the participant is required to perform services in exchange for the award, which is generally one to four years.

In connection with the Brinta acquisition, the Company granted the sellers 497 RSAs with an aggregate fair value of $7,151, based on the value of the Company's Class A common stock on the Acquisition Date. The RSAs vest ratably over a four-year service period, with 25% vesting annually and are recognized on a straight-line basis in the condensed consolidated statements of comprehensive income (loss).

At March 31, 2026, $7,279 of unrecognized compensation expense for RSAs is expected to be recognized over a weighted average period of approximately 3.9 years.

*Performance Stock Units*

In connection with the 2024 ecosio acquisition, current and newly hired employees of ecosio have or may receive RSUs that vest upon continuing service and performance conditions ("Performance Stock Units" or "PSUs"). These performance conditions are based upon ecosio's monthly software revenues meeting specified annual targets over a three-year period. The annual targets are based on a range of performance targets in which grantees may earn a prorated portion of the base number of awards granted up to 100%.

The stock-compensation expense associated with the awards will be accounted for as compensation expense over the vesting periods based on the Company's assessment of the probability of achieving the targets. If the required conditions are not met, no compensation expense is recognized and any previously recognized compensation expense is reversed. During the three months ended March 31, 2026, the Company determined that it was probable that the performance targets for the remaining second and third annual measurement periods would be fully achieved.

The following table summarizes PSU activity for the three months ended March 31, 2026:

---

| | | |
|:---|:---|:---|
|  | <br>**Units** | **Average**<br>**Grant Date Fair**<br>**Value Per Share** |
|  | **(unaudited)** | **(unaudited)** |
| Outstanding at January 1, 2026 | 141 | $50.86 |
| &nbsp;&nbsp;Granted  | 4 | 14.40 |
| &nbsp;&nbsp;Forfeited | (1) | 53.34 |
| Outstanding at March 31, 2026 | 144 | $49.83 |

---

At March 31, 2026, a maximum of $3,276 of unrecognized compensation expense for PSUs, pending achievement of targets, may be recognized over a weighted average period of approximately 1.7 years.

*Employee Stock Purchase Plan*

The ESPP provides eligible employees with rights during each six-month ESPP offering period to purchase shares of the Company's Class A common stock through payroll deductions of up to a specified percentage of their eligible compensation. The purchase price of the shares, in the absence of a contrary designation, is 85% of the lower of the fair value of the Class A common stock on the first or last day of the ESPP offering period. Amounts withheld from participants are included in accrued salaries and benefits in the condensed consolidated balance sheets until such shares are purchased. Amounts withheld from participants for the offering period ending May 31, 2026 aggregated $1,953 as of March 31, 2026. As of March 31, 2026, 6,132 shares of Class A common stock were available for issuance under the ESPP.

As of March 31, 2026, there was approximately $235 of unrecognized ESPP stock-based compensation expense expected to be recognized on a straight-line basis over the remaining term of the six-month offering period ending May 31, 2026.

At March 31, 2026 and 2025, there were two ESPP offering periods open that end May 31, 2026 and 2025, respectively. The fair value of ESPP purchase rights for the offering periods is comprised of the value of the 15% ESPP discount and the value associated with the call or put over the respective ESPP offering period. ESPP offering periods reported in the March 31, 2026 and 2025 financial statements include the periods noted below in the table. The value of the call or put was estimated using the Black-Scholes model with the following assumptions:

---

| | | |
|:---|:---|:---|
|  | **Offering Period Ending** | **Offering Period Ending** |
|  | **5/31/2026** | **5/31/2025** |
| Fair market value of common stock | $19.22 | $54.64 |
| Volatility | 34.5% | 26.4% |
| Expected term (years) | 0.5 | 0.5 |
| Expected dividend yield | -% | -% |
| Risk-free interest rate | 3.8% | 4.4% |

---

Volatility is representative of expected stock price volatility over the offering period based on the Company's historic stock price volatility. The expected term represents the term of the ESPP offering period, which is six months. The Company does not expect to pay dividends. The risk-free interest rate was based on the rate for a U.S. Treasury zero-coupon issue with a term that closely approximates the expected term of the award at the date nearest to the offering term.

**Stock-Based Compensation**

The Company recognized total stock-based compensation expense related to incentive awards, net of forfeitures, as follows:

12. COMMITMENTS AND CONTINGENCIES

In January 2022, the Company filed a complaint against a competitor alleging claims of unfair competition, intentional interference with contractual relations, and trade secret misappropriation. The outcome of the case is subject to a number of uncertainties; therefore, the Company has not recognized any potential impact to the condensed consolidated financial statements related to the outcome of the case.

During the three months ended March 31, 2026 and 2025, the Company recognized $2,727 and $2,425, respectively, for legal expenses associated with the case within the other operating expense, net line of the condensed consolidated statements of comprehensive income (loss).

The Company may become involved in various lawsuits and legal proceedings, which arise in the ordinary course of business. However, litigation is subject to inherent uncertainties, and an adverse result in these or other matters may arise from time to time that may harm the Company's business. The Company is not aware of any such legal proceedings or claims that management believes will have a material adverse effect on its business, financial condition, or operating results.

13. SEGMENT DISCLOSURES

The Company operates its business as one operating segment. Operating segments are defined as components of an enterprise in which separate financial information is evaluated regularly by the chief operating decision maker ("CODM") in deciding how to allocate resources and assess performance. The Company's CODM, the Chief Executive Officer, reviews financial information regularly at the consolidated level. Net income (loss) and adjusted earnings before interest, taxes, depreciation, and amortization ("Adjusted EBITDA"), a non-GAAP measure, are both used as metrics to evaluate performance of the business in deciding whether to reinvest profits into software development, acquisitions or into other areas of the Company. The Company believes that Adjusted EBITDA is a useful supplemental measure to evaluate overall operating performance as it measures business performance by focusing on cash related results and it is an important metric to lenders under the Company's Credit Agreement. The most directly comparable GAAP measure to Adjusted EBITDA is net income (loss).

The CODM monitors consolidated forecasted versus actual net income (loss) and Adjusted EBITDA results for the purpose of determining the general health of the Company and assessing the performance of the Company as compared to management's expectations.

In determining interim provisions for income taxes, the Company uses the annual estimated effective tax rate applied to the actual year-to-date income (loss) adjusted for discrete items arising year-to-date. The Company's effective tax rate differs from the U.S. federal statutory rate of 21% primarily due to state taxes, foreign taxes, tax benefits on the exercises and vesting of stock awards, tax credits, limitations on deductions of certain employees' compensation under Internal Revenue Code Section 162(m), fluctuations in valuation allowances on net deferred tax assets established for U.S. and certain foreign jurisdictions, and fluctuations in nondeductible contingent consideration liabilities.

The income tax benefit for the three months ended March 31, 2026 was primarily attributable to fluctuations in valuation allowances on net deferred tax assets established for U.S. and certain foreign jurisdictions as well as the impact from the estimated annual effective tax rate applied to pre-tax loss for the three months ended March 31, 2026. This income tax benefit was partially offset by tax expense from stock-based awards exercised or vested, net of limitations on deductions of certain employees' compensation. The income tax benefit for the three months ended March 31, 2025 was primarily attributable to tax benefits from stock-based awards exercised or vested, net of limitations on deductions of certain employees' compensation, as well as tax credits. This income tax benefit was partially offset by fluctuations in valuation allowances on net deferred tax assets established for U.S. and certain foreign jurisdictions as well as income tax expense from profitable jurisdictions and on income allocated to state jurisdictions.

15. RESTRUCTURING

On April 28, 2026, the Company announced its Board approved a global Value Creation Plan (the "Plan") with the intention to become a more AI-enabled company, focusing investments on key growth opportunities and driving operational efficiency to better align the Company's workforce and resources with its long-term strategic priorities. The Plan includes a reduction in force of approximately 170 employees along with a significant reduction of third party spend across the Company. In connection with the Plan, the Company recognized a pre-tax charge of $6,170 during the three months ended March 31, 2026, which is included in the general and administrative expense line of the condensed consolidated statements of comprehensive income (loss). This charge consists primarily of cash expenditures related to employee severance, notice pay, statutory termination indemnities, and other employee separation benefits. All related cash payments are expected to be made during 2026. Any changes to the estimates or timing of the Plan will be reflected in the Company's results of operations in future periods. Total liabilities of $6,170 related to the Plan are recorded in the accrued salaries and benefits line of the condensed consolidated balance sheet at March 31, 2026.

---

*You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the condensed consolidated financial statements and the notes thereto included elsewhere in this Quarterly Report on Form 10-Q, as well as our audited consolidated financial statements and related notes as disclosed in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (the "SEC") on February 24, 2026 (the "2025 Annual Report"). In addition to historical financial information, the following discussion contains forward-looking statements that reflect our plans, estimates, beliefs, and expectations that involve risks and uncertainties. Our actual results and the timing of events could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Quarterly Report on Form 10-Q, particularly in the section titled "Special Note Regarding Forward-Looking Statements" above, and in Part I, Item 1A of the 2025 Annual Report and as may be subsequently updated by our other SEC filings.*

**Overview** 

Vertex is a leading provider of enterprise compliance technology for global commerce. Our software, data, and services help businesses operate with confidence by automating and governing transaction-based compliance obligations that arise wherever they buy, sell, and move goods and services around the world. Our mission is to deliver the most trusted tax technology enabling global businesses to transact, comply, and grow with confidence. Vertex provides cloud-based and on-premise solutions that can be tailored to specific industries for every major line of indirect tax, including sales and consumer use, value added (including e-invoicing), and payroll. Headquartered in North America, and with offices in South America and Europe, Vertex employs over 2,100 professionals and serves companies across the globe.

We derive the majority of our revenue from software subscriptions. These subscriptions include use of our software and ongoing monthly content updates. Our software is offered on a subscription basis to our customers, regardless of their deployment preferences. On-premise subscriptions and cloud-based subscriptions are typically sold through one- to three-year contracts. We bill the majority of our customers annually in advance of the subscription period.

Our customers include the majority of the Fortune 500, as well as a majority of the top 10 companies by revenue in multiple industries such as retail, technology, and manufacturing, in addition to leading marketplaces. Our customer base also includes many of Europe's largest companies in the industrial and chemical manufacturing, pharmaceutical, medical device and metals and mining industries. As our customers expand geographically and pursue omnichannel business models, their tax determination and compliance requirements increase and become more complex, providing sustainable organic growth opportunities for our business. Our flexible, tiered transaction-based pricing model also results in our customers growing their spend with us as they grow and continue to use our solutions. We principally price our solutions based on a customer's revenue base, in addition to a number of other factors.

We employ a hybrid deployment model to align to our customers' technology preferences for their core financial management software across on-premise, cloud deployments or any combination of these models. Over time, we expect both existing and newly acquired customers to continue to shift towards cloud deployment models. Cloud-based subscription sales to new customers have grown at a faster rate than on-premise software subscription sales, which is a trend that we expect to continue over time. We generated 58% and 53% of software subscription revenue from cloud-based subscriptions during the three months ended March 31, 2026 and 2025, respectively. While our on-premise software subscription revenue comprised 42% and 47% of our software subscription revenue during the three months ended March 31, 2026 and 2025, respectively, it continues to decrease as a percentage of total software subscriptions revenues as cloud-based subscriptions grow.

We license our solutions primarily through our direct sales force, which focuses on selling to qualified leads provided by our marketing efforts, and through our network of referral partners. We also utilize indirect sales to a lesser extent to efficiently grow and scale our enterprise and mid-market revenues.

[**Table of Contents**](#TOC)

Our partner ecosystem is a differentiating, competitive strength in both our software development and our sales and marketing activities. We integrate with key technology partners that span Enterprise Resource Planning ("ERP"), Customer Relationship Management, procurement, billing, Point of Sale and e-commerce. These partners include Adobe/Magento, Coupa, Kintsugi AI, Inc., Microsoft Dynamics, NetSuite, Oracle, Salesforce, SAP, SAP Ariba, Shopify, Workday and Zuora. We also collaborate with numerous accounting firms who have built implementation practices around our software to serve their customer base.

We believe that global commerce and the compliance environment provides durable and accelerating growth opportunities for our business. We generated revenue of $196.6 million and $177.1 million for the three months ended March 31, 2026 and 2025, respectively. We had net income (loss) of $(2.5) million and $11.1 million for the three months ended March 31, 2026 and 2025, respectively. These amounts are presented in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP").

We define Adjusted EBITDA as net loss or income before interest, taxes, depreciation, and amortization, as adjusted to exclude charges for stock-based compensation expense, amortization of cloud computing arrangement implementation costs, severance expense, acquisition contingent consideration, changes in the fair value of acquisition contingent earn-outs, acquisition-related retained employee compensation, and transaction costs. Adjusted EBITDA was $44.1 million and $37.2 million for the three months ended March 31, 2026 and 2025, respectively. Adjusted EBITDA is a non-GAAP financial measure. Refer to "Management's Discussion and Analysis of Financial Condition and Results of Operations—Key Business Metrics" and "Management's Discussion and Analysis of Financial Condition and Results of Operations—Use and Reconciliation of Non-GAAP Financial Measures" for further discussion of key business metrics and non-GAAP financial measures and their comparison to GAAP financial measures.

We believe that we currently have ample liquidity and capital resources to continue to meet our operating needs, and our ability to continue to service our debt or other financial obligations is not currently impaired. For a further description of our liquidity, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources."

**Recent Developments**

*Brinta Acquisition*

On March 2, 2026 (the "Acquisition Date"), we completed our acquisition of 100% of the equity interests of Finta Inc. and its subsidiaries (collectively, "Brinta" or the "Acquisition"). Headquartered in Uruguay, Brinta is a Latin American provider of business-to-business integration services, specializing in indirect tax calculation, tax filing, and e-invoicing. We plan to fully integrate Brinta, leveraging its e-invoicing capabilities to immediately expand the Company's coverage across the Latin American region. Total purchase consideration for the Acquisition was $22.0 million, net of $0.04 million of cash acquired. For further information refer to Note 3, "Acquisitions" to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

*Value Creation Plan*

On April 28, 2026, we announced that our Board approved a global Value Creation Plan (the "Plan") with the intention to become a more AI-enabled company, focusing investments on key growth opportunities and driving operational efficiency to better align our workforce and resources with our long-term strategic priorities. The Plan includes a reduction in force of approximately 170 employees along with a significant reduction of third party spend across the Company. In connection with the Plan, we recognized a pre-tax charge of $6.2 million in the three months ended March 31, 2026. This charge consists primarily of cash expenditures related to employee severance, notice pay, statutory termination indemnities, and other employee separation benefits. All related cash payments are expected to be made during 2026. Any changes to our estimates or timing of the Plan will be reflected in our results of operations in future periods.

We expect the savings from the Plan to yield an improvement of Adjusted EBITDA of between $14.0 million to $16.0 million during fiscal year 2026 and forecast fully annualized cash savings of approximately $60.0 million to $70.0 million

[**Table of Contents**](#TOC)

per year beginning in fiscal 2027. For further information refer to Note 15, "Restructuring" to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

**Components of Our Results of Operations**

**Revenue**

We generate revenue from software subscriptions and services.

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration expected to be received in exchange for those products or services. We enter into contracts that include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of allowance for subscription and non-renewal cancellations and any taxes collected from customers that are subsequently remitted to governmental authorities.

**Software Subscriptions**

Licenses for on-premise software subscriptions provide the customer with a right to use the software as it exists when made available to the customer. Customers purchase a subscription to these licenses, which includes the related software and tax content updates and product support. The updates and support, which are part of the subscription agreement, are essential to the continued utility of the software; therefore, we have determined the software and the related updates and support to be a single performance obligation. Accordingly, when on-premise software is licensed, the revenue associated with this combined performance obligation is recognized ratably over the license term as these subscriptions are provided for the duration of the license term. Revenue recognition begins on the later of the beginning of the subscription period or the date the software is made available to the customer to download.

Our cloud-based subscriptions allow customers to use Vertex-hosted software over the contract period without taking possession of the software. The contracts are generally for one to three years and are generally billed annually in advance of the subscription period. Our cloud-based offerings also include related updates and support. Revenue recognition begins on the later of the beginning of the subscription period or the date the customer is provided access to the cloud-based solutions. All services within the cloud-based contracts consistently provide a benefit to the customer during the subscription period; thus, the associated revenue is recognized ratably over the subscription period.

Revenue is impacted by the timing of sales and our customers' growth or contractions resulting in their need to expand or contract their subscription usage, the purchase of new solutions, or the non-renewal of existing solutions. In addition, revenue will fluctuate with the cessation of extended product support fees charged for older versions of our software subscription solutions when they are retired and these fees are no longer charged. Contracts for on-premise licenses permit cancellations at the end of the license term. Legacy cloud-based subscription contracts for multi-year periods previously provided customers the right to terminate their contract for services prior to the end of the subscription period at a significant penalty. This penalty requires the payment of a percentage of the remaining months of the then-current contract term. Current cloud-based contracts do not contain such termination rights. Terminations of cloud-based subscriptions prior to the end of the subscription term have occurred infrequently, and the impact has been immaterial. The allowance for subscription and non-renewal cancellations reflects an estimate of the amount of such cancellations and non-renewals based on past experience, current information, and forward-looking economic considerations.

**Services Revenue**

We generate services revenue primarily in support of our customers' needs associated with our software and to enable them to realize the full benefit of our solutions. These software subscription-related services include configuration, data migration and implementation, and premium support and training. In addition, we generate services revenue through our managed services offering which allows customers to outsource all or a portion of their indirect tax operations to us. These services include indirect tax return preparation, filing and tax payment, and notice management. We generally bill for

[**Table of Contents**](#TOC)

services on a per-transaction or time and materials basis, and we recognize revenue from deliverable-based professional services as services are performed.

Fluctuations in services revenue are directly correlated to fluctuations in our subscription revenues with respect to implementation and training services as we have historically experienced an attachment rate to subscription sales for these services of approximately 60%. In addition, our managed services offering has continued to experience increased revenues associated with returns processing volume increases attributable to regulatory changes, as customers expanded their tax filings into more jurisdictions.

**Cost of Revenue**

**Software Subscriptions**

Cost of software subscriptions revenue consists of costs related to providing and supporting our software subscriptions and includes personnel and related expenses, including salaries, benefits, bonuses, and stock-based compensation. In addition, cost of revenue includes direct costs associated with information technology, such as data center and software hosting costs, and tax content maintenance. Cost of software subscriptions revenue also includes amortization associated with capitalized internal-use software for cloud-based subscription solutions and software developed for sale for new products and enhancements to existing products, and costs associated with the amortization of certain acquired intangible assets. We plan to continue to significantly expand our infrastructure and personnel to support our future growth and increases in transaction volumes of our cloud-based solutions, including through acquisitions. We expect growth in our business will result in an increase in cost of software subscriptions revenue in absolute dollars.

**Services**

Cost of services revenue consists of direct costs of software subscription-related services and our managed services offering. These costs include personnel and related expenses, including salaries, benefits, bonuses, stock-based compensation, and the cost of third-party contractors and other direct expenses. We plan to continue to expand our infrastructure and personnel as necessary to support our future growth in our managed service offerings and related increases in our service revenue. We expect growth in our business will result in an increase in the cost of services revenue in absolute dollars.

**Research and Development**

Research and development expenses consist primarily of personnel and related expenses for our research and development activities, including salaries, benefits, bonuses and stock-based compensation, and the cost of third-party developers and other contractors. Research and development costs, other than software development expenses qualifying for capitalization, are expensed as incurred.

We devote substantial resources to developing new products and enhancing existing products, conducting quality assurance testing, improving our core technology, and integrating acquired technology with our products. We believe continued investments in research and development are critical to attain our strategic objectives and expect research and development costs to increase in absolute dollars. These investments include enhancing our solution offerings to address changing customer needs to support their growth, as well as implementing changes required to keep pace with our partners' technology to ensure the continued ability of our solutions to work together and deliver value to our customers. The market for our solutions is characterized by rapid technological change, frequent new product and service introductions and enhancements, changing customer demands, and evolving industry standards. As a result, although we are making significant research and development expenditures, certain of which may be capitalized, there is no guarantee these solutions will be accepted by the market. This could result in increased costs or an impairment of capitalized development costs with no resulting future revenue benefit.

[**Table of Contents**](#TOC)

**Selling and Marketing Expenses**

Selling and marketing expenses consist primarily of personnel and related expenses in support of sales and marketing efforts. These costs include salaries, benefits, bonuses and stock-based compensation. In addition, selling and marketing expenses include costs related to advertising and promotion efforts, branding costs, partner-based commissions, costs associated with our annual customer conferences and amortization of certain acquired intangible assets. We intend to continue to invest in our sales and marketing capabilities in the future to continue to increase our brand awareness and expect these costs to increase on an absolute dollar basis as we grow our business and continue to expand our market and partner ecosystem penetration. Sales and marketing expense in absolute dollars and as a percentage of total revenue may fluctuate from period-to-period based on total revenue levels and the timing of our investments in our sales and marketing functions, as these investments will occur in advance of experiencing the benefits from such investments and may vary in scope and scale over future periods.

**General and Administrative** 

General and administrative expenses consist primarily of personnel and related expenses for administrative, finance, information technology, legal, risk management, facilities, and human resources staffing, including salaries, benefits, bonuses, severance, stock-based compensation, professional fees, insurance premiums, facility costs, amortization of cloud computing arrangement implementation costs, and other internal support and infrastructure costs. Additionally, the three months ended March 31, 2026 period includes severance costs related to the Plan. For further information refer to Note 15, "Restructuring" to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

We expect our general and administrative expenses to increase in absolute dollars as we continue to expand our operations, hire additional personnel, and integrate current and future acquisitions.

**Depreciation and Amortization**

Depreciation and amortization expense consists of the allocation of purchased and developed asset costs over the future periods benefited by the use of these assets. These assets include leasehold improvements for our facilities, computers and equipment needed to support our customers and our internal infrastructure and capitalized internal-use software associated with our internal tools. Depreciation and amortization will fluctuate in correlation with our ongoing investment in internal infrastructure costs to support our growth.

**Change in Fair Value of Acquisition Contingent Earn-Outs** 

The change in fair value of acquisition contingent earn-outs consists of fair value adjustments to our Cash Earn-outs (as defined below) and Stock Earn-outs (as defined below) (collectively with the Cash Earn-outs, the "Earn-outs") related to our 2024 acquisition of ecosio GmbH ("ecosio"). The Earn-outs will be revalued and adjusted quarterly until the end of the Earn-out periods.

**Other Operating Expense (Income), net**

Other operating expense (income), net consists primarily of transactions costs associated with merger and acquisition activities, periodic remeasurement of contingent consideration associated with completed acquisitions, realized gains and losses on foreign currency changes, and other operating gains and losses. These amounts will fluctuate as a result of ongoing merger and acquisition activities and for changes in foreign currency rates.

**Interest Expense (Income), net**

Interest expense (income), net reflects the net amount of our interest expense and interest income within the same period.

[**Table of Contents**](#TOC)

Interest expense consists primarily of interest incurred related to the Notes (as defined below), a Credit Agreement (as defined below), and leases. Interest expense includes amortization of deferred financing fees over the term of the credit facility or write-downs of such costs upon redemption of debt. Interest expense will vary as a result of fluctuations in the level of debt outstanding as well as interest rates on such debt.

Interest income reflects earnings on investments of our cash on hand and our investment securities. Interest income will vary as a result of fluctuations in the future level of funds available for investment and the rate of return available in the market on such funds.

**Income Tax Expense (Benefit)** 

Income tax expense (benefit) consists primarily of federal, foreign, state, and local taxes on our loss or income. In determining our annualized effective income tax rates, net deferred tax assets, valuation allowances, and cash paid for income taxes, we are required to make judgments and estimates about domestic and foreign profitability, the timing and usage of net operating loss and credit carryforwards, applicable tax rates, and transfer pricing methodologies. Judgments and estimates related to our projections and assumptions are inherently uncertain; therefore, actual results could materially differ from our projections.

Revenues increased $19.6 million, or 11.1%, to $196.6 million for the three months ended March 31, 2026 compared to $177.1 million for the same period in 2025. The increase in software subscriptions revenues of $16.4 million, or 10.9%, was primarily driven by increases from our existing customers through cross-selling new products, and to a lesser extent, increases due to expanded use and price increases. Software subscriptions revenues derived from new customers averaged 6.0% and 8.1% of total software subscriptions revenues in the three months ended March 31, 2026 and 2025, respectively.

The $3.2 million increase in services revenues was primarily driven by a $1.5 million increase in recurring services revenues due to returns processing volume increases related to customer business growth and regulatory changes as customers expanded their tax filings into more jurisdictions, as well as an increase in interest received from our funds held for customers. Additionally, our managed services offering experienced a $1.7 million increase in service revenues associated with the growth in subscription revenues, which includes new customers implementing our solutions and existing customers upgrading to newer versions of our solutions.

---

Cost of software subscriptions revenues increased $6.9 million, or 15.7%, to $51.2 million for the three months ended March 31, 2026 compared to $44.2 million for the same period in 2025. The increase was primarily driven by a $4.2 million increase in depreciation and amortization of capitalized software and acquired intangible assets associated with our ongoing investments in internal-use software for cloud-based subscription solutions, software developed for sale for new products and enhancements to existing products, and costs associated with the increased amortization of acquired intangible assets. Additionally, there was a $2.7 million increase in costs of personnel supporting period-over-period growth of sales and customers, ongoing infrastructure investments and support costs to enable the continued expansion of customer transaction volumes for our cloud-based subscription customers.

Research and development expenses increased $3.7 million, or 17.5%, to $24.6 million for the three months ended March 31, 2026 compared to $20.9 million for the same period in 2025. This increase in research and development expenses was primarily due to an increase in personnel costs related to development work associated with new solutions to address end-to-end data analysis and compliance needs of our customers, and continued expansion of connectors and application program interfaces to customer ERP and other software platforms. Additionally, this increase reflects additional research and development investments related to the commercialization of our AI-based Smart Categorization product, other AI-related internal tools and new product initiatives, and other emerging technologies.

Selling and marketing expenses increased $4.5 million, or 9.3%, to $52.6 million for the three months ended March 31, 2026 compared to $48.2 million for the same period in 2025. This increase was primarily driven by a $2.9 million increase in payroll and related expenses associated with the growth in period-over-period subscription sales and services revenues and expansion of our partner and channel management programs. Additionally, there was an increase of $1.5 million in advertising and promotional spending related to expanded brand awareness efforts.

Change in fair value of acquisition contingent earn-outs was $(5.7) million for the three months ended March 31, 2026 due to adjustments to the fair values of our ecosio acquisition contingent Cash Earn-outs and Stock Earn-outs of $(0.3) million and $(5.4) million, respectively. Change in fair value of acquisition contingent earn-outs was $(14.7) million for the three months ended March 31, 2025 due to adjustments to the fair values of our ecosio acquisition contingent Cash Earn-outs and Stock Earn-outs of $1.7 million and $(16.4) million, respectively.

| Income tax benefit | $(7139) | $(5105) | $(2034) | 39.8% |

---

Income tax benefit was $7.1 million and $5.1 million for the three months ended March 31, 2026 and 2025, respectively. The period-over-period change was primarily driven by increased tax benefits from fluctuations in valuation allowances on net deferred tax assets established for U.S. and certain foreign jurisdictions, as well the impact from the estimated annual effective tax rate applied to pre-tax loss for the three months ended March 31, 2026. These income tax benefit increases were offset partially by a decreased tax benefit on exercises and vesting of stock awards recognized, net of limitations on deductions of certain employees' compensation, fluctuations in nondeductible contingent consideration liabilities as well as fluctuations in tax credits.

**Liquidity and Capital Resources** 

As of March 31, 2026, we had unrestricted cash and cash equivalents of $252.5 million. Our primary sources of capital include sales of our solutions, proceeds from bank lending facilities, and the offering of existing or future classes of stock.

As of March 31, 2026, we had a credit agreement with a banking syndicate (the "Credit Agreement") that provides a $300.0 million revolving facility (the "Line of Credit"). There were no outstanding borrowings under the Credit Agreement at March 31, 2026.

On April 26, 2024, we closed a private offering of $345.0 million aggregate principal amount of 0.750% Convertible Senior Notes due in 2029 (the "Notes"). The net proceeds from the offering of the Notes were $333.7 million, after deducting the initial purchasers' discount and commissions, and other transaction and offering expenses. For further information on the Notes, refer to our 2025 Annual Report on Form 10-K.

We believe that our existing cash resources and our Line of Credit will be sufficient to meet our capital requirements and fund our operations for the next 12 months as well as our longer-term liquidity needs. If an early conversion notice occurs on our Notes, we have the option to pay cash, shares of our Class A common stock, or a combination of both. Also, we expect to have access to additional sources of funds in the capital markets, and we may, from time to time, seek additional capital through a combination of additional debt and/or equity financings. If we were to raise additional funds by issuing equity securities, our stockholders may experience dilution. Debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. Additional financing may not be available at all, or in amounts or on terms unacceptable to us.

The following table presents a summary of our cash flows for the periods indicated:

***Operating Activities.*** Net cash provided by operating activities of $38.0 million for the three months ended March 31, 2026 consisted of net loss of $(2.5) million, adjusted for non-cash charges of $46.1 million, and cash outflows of $(5.6) million related to changes in operating assets and liabilities. The change in operating assets and liabilities was primarily driven by a decrease in accrued and deferred compensation and accrued expenses, and an increase in prepaid expenses and other current assets due to the timing of cash payments during the period. These changes were partially offset by a decrease

[**Table of Contents**](#TOC)

in accounts receivable and an increase in deferred revenue, primarily due to customer growth and the timing of cash collections during the period.

Net cash provided by operating activities of $14.8 million for the three months ended March 31, 2025 consisted of net income of $11.1 million, adjusted for non-cash charges of $30.3 million, which were partly offset by cash outflows of $(26.7) million related to changes in operating assets and liabilities. The change in operating assets and liabilities was primarily driven by a decrease in accrued and deferred compensation, and an increase in prepaid expenses and other current assets due to the timing of cash payments during the period. These changes were partially offset by an increase in deferred revenue and a decrease in accounts receivable, primarily due to customer growth and the timing of cash collections during the period.

***Investing Activities.*** Net cash used in investing activities of $52.3 million for the three months ended March 31, 2026 consisted of investments in property and equipment, and capitalized software of $24.7 million and $5.7 million, respectively, related to investments in infrastructure, new products, and enhancements to existing products. Additionally, we paid $22.0 million for our acquisition of Brinta. For further information on the Acquisition, refer to Note 3, "Acquisitions" to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

Net cash used in investing activities of $17.8 million for the three months ended March 31, 2025 consisted of investments in property and equipment, and capitalized software of $21.4 million and $5.7 million, respectively, related to investments in infrastructure, new products, and enhancements to existing products. Additionally, we invested $2.4 million in available-for-sale investment securities, which was more than offset by proceeds of $11.6 million received during the period for sales and maturities in our investment securities.

***Financing Activities.*** Net cash used in financing activities of $53.3 million for the three months ended March 31, 2026 consisted of $20.0 million in payments for the repurchases of our Class A common stock under our Repurchase Program, $19.6 million in payments related to our ecosio Cash Earn-out, $7.1 million in payments for taxes related to the net share settlement of stock-based awards, and a $6.6 million decrease in customer funds obligations, primarily due to timing differences between receipt of funds from customers and taxing jurisdiction withdrawals of these funds. For further information on the Cash Earn-outs, refer to Note 4, "Financial Instruments and Fair Value Measurements" to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

Net cash used in financing activities of $20.7 million for the three months ended March 31, 2025 consisted of $25.0 million in payments for taxes related to the net share settlement of stock-based awards, which were partially offset by a $3.2 million increase in customer funds obligations, primarily due to timing differences between receipt of funds from customers and taxing jurisdiction withdrawals of these funds, and $1.2 million in proceeds from the exercise of stock options.

***Debt*.** As of March 31, 2026, we had a $300.0 million Line of Credit with no outstanding borrowings in connection with our Credit Agreement. As of March 31, 2026, we had $345.0 million aggregate principal amount of debt outstanding related to our Notes. For further information on our debt obligations, refer to Note 8, "Debt" to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

***Repurchase Program.*** On October 30, 2025, the Board authorized a stock repurchase program for up to $150.0 million of our outstanding shares of Class A common stock (the "Repurchase Program"). During the first three months ended March 31, 2026, we repurchased 1,370,948 shares of our Class A common stock for an aggregate amount of $20.0 million and have $119.9 million remaining for purchases under our authorization.

The timing and actual number of shares repurchased under the Repurchase Program depend on a variety of factors, including price, general business and market conditions, and other investment opportunities. Shares may be repurchased through open market purchases or privately negotiated transactions, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Exchange Act. Our Repurchase Program has no termination date and may be suspended, delayed, discontinued, or accelerated at any time. Any repurchased shares will be available for use in connection with our stock plans and for other corporate purposes. For further information on our Repurchase Program,

refer to Note 9, "Stockholders' Equity" to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

**Funds Held for Customers and Customer Funds Obligations**

We maintain trust accounts with financial institutions, which allow our customers to outsource their tax remittance functions to us. We have legal ownership over the accounts utilized for this purpose. Funds held for customers represent cash and cash equivalents that, based upon our intent, are restricted solely for satisfying the obligations to remit funds relating to our tax remittance services. Funds held for customers are not commingled with our operating funds.

Customer funds obligations represent our contractual obligations to remit collected funds to satisfy customer tax payments. Customer funds obligations are included as a current liability on our condensed consolidated balance sheets as the obligations are expected to be settled within one year. Cash flows related to changes in customer funds obligations liability are presented as cash flows from financing activities.

**Contractual Obligations and Commitments**

As of March 31, 2026, we have no outstanding borrowings under our Line of Credit. Our Notes are due in May 2029. We expect to continue to fund debt maturities and interest payments with cash flows generated from operations, existing cash and cash equivalents, or proceeds from additional financing. For further information on our debt obligations, refer to Note 8, "Debt" to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

There have been no material updates or changes to our contractual obligations and commitments compared to contractual obligations and commitments described in our 2025 Annual Report.

**Key Business Metrics**

We regularly review the metrics identified below to evaluate growth trends, measure our performance, formulate financial projections and make strategic decisions.

***Annual Recurring Revenue ("ARR") and Average Annual Revenue Per Customer ("AARPC").***

We derive the vast majority of our revenue from recurring software subscriptions. We believe ARR provides us with visibility to our projected software subscription revenue in order to evaluate the health of our business. Because we recognize subscription revenue ratably, we believe investors can use ARR to measure our expansion of existing customer revenues, new customer activity, and as an indicator of future software subscription revenues. ARR is based on monthly recurring revenue ("MRR") from software subscriptions for the most recent month at period end, multiplied by twelve. MRR is calculated by dividing the software subscription price, inclusive of discounts, by the number of subscription covered months. MRR only includes customers with MRR at the end of the last month of the measurement period.

AARPC represents average annual revenue per customer and is calculated by dividing ARR by the number of software subscription customers at the end of the respective period.

| Annual Recurring Revenue | $687.6 | $618.5 | $69.1 | 11.2% |

---

ARR increased by $69.1 million, or 11.2%, at March 31, 2026, as compared to March 31, 2025. The increase was primarily driven by $32.9 million of growth in revenues from existing customers through their expanded use of our solutions as well as price increases, and $36.2 million in growth of subscriptions of our solutions to new customers.

[**Table of Contents**](#TOC)

We had 4,895 direct customers and AARPC was approximately $140,464 at March 31, 2026. At March 31, 2025, we had 4,888 direct customers and approximately $126,534 of AARPC. The increase in AARPC was primarily due to expansion of usage by existing customers and adding new scaled customers through organic growth.

***Net Revenue Retention Rate ("NRR").***

We believe that our NRR provides insight into our ability to retain and grow revenue from our customers, as well as their potential long-term value to us. We also believe it demonstrates to investors our ability to expand existing customer revenues, which is one of our key growth strategies. Our NRR refers to the ARR expansion during the 12 months of a reporting period for all customers who were part of our customer base at the beginning of the reporting period. Our NRR calculation takes into account any revenue lost from departing customers or those who have downgraded or reduced usage, as well as any revenue expansion from migrations, new licenses for additional products or contractual and usage-based price changes.

|  | **2026** | **2025** |
| Net Revenue Retention Rate  | 105% | 109% |

---

NRR decreased by 3.8%, at March 31, 2026, as compared to March 31, 2025. The decrease was largely due to lower growth of additional entitlements as our customers' annual growth has slowed, keeping them within current bands of usage, as well as delayed deal activity seen for some of our large multinational customers due to the macroeconomic environment.

***Gross Revenue Retention Rate ("GRR").***

We believe our GRR provides insight into and demonstrates to investors our ability to retain revenues from our existing customers. Our GRR refers to how much of our MRR we retain each month after reduction for the effects of revenues lost from departing customers or those who have downgraded or reduced usage. GRR does not take into account revenue expansion from migrations, new licenses for additional products or contractual and usage-based price changes. GRR does not include revenue reductions resulting from cancellations of customer subscriptions that are replaced by new subscriptions associated with customer migrations to a newer version of the related software solution.

***Adjusted EBITDA and Adjusted EBITDA Margin.***

We believe that Adjusted EBITDA is a measure widely used by securities analysts and investors to evaluate the financial performance of our company and other companies. We believe that Adjusted EBITDA and Adjusted EBITDA margin are useful as supplemental measures to evaluate our overall operating performance as they measure business performance focusing on cash related charges and because they are important metrics to lenders under our Credit Agreement. We define Adjusted EBITDA as net loss or income before interest, taxes, depreciation, and amortization, as adjusted to exclude charges for stock-based compensation expense, amortization of cloud computing arrangement implementation costs, severance expense, acquisition contingent consideration, changes in the fair value of acquisition contingent earn-outs, acquisition-related retained employee compensation, and transaction costs. Adjusted EBITDA margin represents Adjusted EBITDA divided by total revenues for the same period. For purposes of comparison, our net income (loss) was $(2.5) million and $11.1 million for the three months ended March 31, 2026 and 2025, respectively, while our net income (loss) margin was (1.3)% and 6.3% over the same periods, respectively. We are unable to reconcile forward-looking Adjusted EBITDA to net income (loss), the most directly comparable GAAP financial measure, without unreasonable efforts because we are currently unable to predict with a reasonable degree of certainty the type and extent

[**Table of Contents**](#TOC)

of certain items that would be expected to impact net income (loss) for these periods but would not impact Adjusted EBITDA.

The increase in Adjusted EBITDA for the three months ended March 31, 2026 of $6.8 million over the comparable period in 2025 was primarily driven by a $15.6 million increase in non-GAAP gross profit, which was partially offset by increases of $4.9 million in non-GAAP selling and marketing expense, $4.2 million in non-GAAP research and development expense, and $0.4 million in non-GAAP general and administrative expense. Adjusted EBITDA margin increased to 22.4% for the three months ended March 31, 2026 compared to 21.0% for the comparable period in 2025, primarily due to increased operating leverage and realized efficiencies from prior year strategic investments in our global infrastructure and core business processes.

***Free Cash Flow and Free Cash Flow Margin.***

We use free cash flow as a critical measure in the evaluation of liquidity in conjunction with related GAAP amounts. We also use this measure when considering available cash, including for decision-making purposes related to dividends and discretionary investments. We consider free cash flow to be an important measure for investors because it measures the amount of cash we generate from our operations after our capital expenditures and capitalization of software development costs. In addition, we base certain of our forward-looking estimates and budgets on free cash flow and free cash flow margin. We define free cash flow as the total of net cash provided by operating activities less purchases of

[**Table of Contents**](#TOC)

property and equipment and capitalized software. We define free cash flow margin as free cash flow divided by total revenues for the same period.

Our net cash provided by operating activities was $38.0 million and $14.8 million for the three months ended March 31, 2026 and 2025, respectively, while our operating cash flow margin was 19.3% and 8.4% over the same periods, respectively.

Free cash flow increased by $19.9 million for the three months ended March 31, 2026 as compared to the same period in 2025. This increase was primarily driven by a $23.2 million increase in cash provided by operating activities, resulting from favorable changes in working capital components and the timing of certain operational expenditures. Free cash flow margin increased to 3.9% for the three months ended March 31, 2026 compared to (6.9)% for the same period in 2025.

**Use and Reconciliation of Non-GAAP Financial Measures**

In addition to our results determined in accordance with GAAP, we have calculated Adjusted EBITDA, Adjusted EBITDA margin, free cash flow, free cash flow margin, non-GAAP cost of revenues, non-GAAP gross profit, non-GAAP gross margin, non-GAAP research and development expense, non-GAAP selling and marketing expense, non-GAAP general and administrative expense, non-GAAP operating income, and non-GAAP net income, which are each non-GAAP financial measures. We have provided tabular reconciliations of each of these non-GAAP financial measures to its most directly comparable GAAP financial measure.

We use these non-GAAP financial measures to understand and compare operating results across accounting periods, for internal budgeting and forecasting purposes, and to evaluate financial performance. We use non-GAAP financial measures of free cash flow and free cash flow margin to evaluate liquidity. Our non-GAAP financial measures are presented as supplemental disclosure as we believe they provide useful information to investors and others in understanding and evaluating our results, prospects, and liquidity period-over-period without the impact of certain items that do not directly correlate to our operating performance and that may vary significantly from period to period for reasons unrelated to our operating performance, as well as comparing our financial results to those of other companies. Our definitions of these non-GAAP financial measures may differ from similarly titled measures presented by other companies, and therefore, comparability may be limited. In addition, other companies may not publish these or similar metrics. Thus, our non-GAAP financial measures should be considered in addition to, not as a substitute for, or in isolation from, the financial information prepared in accordance with GAAP financial measures, and should be read in conjunction with the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

[**Table of Contents**](#TOC)

**Additional Non-GAAP Financial Measures** 

In addition to Adjusted EBITDA, Adjusted EBITDA margin, free cash flow, and free cash flow margin calculated and discussed in "Key Business Metrics," the following additional non-GAAP financial measures are calculated and presented further below:

● Non-GAAP cost of revenues, software subscriptions is determined by adding back to GAAP cost of revenues, software subscriptions, the stock-based compensation expense, and depreciation and amortization of capitalized software and acquired intangible assets included in cost of subscription revenues for the respective periods.

● Non-GAAP cost of revenues, services is determined by adding back to GAAP cost of revenues, services, the stock-based compensation expense included in cost of revenues, services for the respective periods.

● Non-GAAP gross profit is determined by adding back to GAAP gross profit the stock-based compensation expense, and depreciation and amortization of capitalized software and acquired intangible assets included in cost of subscription revenues for the respective periods.

● Non-GAAP gross margin is determined by dividing non-GAAP gross profit by total revenues for the respective periods.

● Non-GAAP research and development expense is determined by adding back to GAAP research and development expense the stock-based compensation expense and transaction costs related to acquired technology included in research and development expense for the respective periods.

● Non-GAAP selling and marketing expense is determined by adding back to GAAP selling and marketing expense the stock-based compensation expense and the amortization of acquired intangible assets included in selling and marketing expense for the respective periods.

● Non-GAAP general and administrative expense is determined by adding back to GAAP general and administrative expense the stock-based compensation expense, amortization of cloud computing implementation costs, severance expense, acquisition-related retained employee compensation, and transaction costs included in general and administrative expense for the respective periods.

● Non-GAAP operating income is determined by adding back to GAAP loss or income from operations the stock-based compensation expense, depreciation and amortization of capitalized software and acquired intangible assets, amortization of cloud computing implementation costs, severance expense, acquisition contingent consideration, changes in the fair value of acquisition contingent earn-outs, acquisition-related retained employee compensation, and transaction costs included in GAAP loss or income from operations for the respective periods.

● Non-GAAP net income is determined by adding back to GAAP net income or loss income tax benefit or expense, stock-based compensation expense, depreciation and amortization of capitalized software and acquired intangible assets, amortization of cloud computing implementation costs, severance expense, acquisition contingent consideration, changes in the fair value of acquisition contingent earn-outs, acquisition-related retained employee compensation, and transaction costs included in GAAP loss or income from operations for the respective periods, to determine non-GAAP income or loss before income taxes. Non-GAAP income or loss before income taxes is then adjusted for income taxes calculated using the respective statutory tax rates for applicable jurisdictions, which for purposes of this determination were assumed to be 25.5%.

We encourage investors and others to review our financial information in its entirety, not to rely on any single financial measure and to view these non-GAAP financial measures in conjunction with the related GAAP financial measures.

| **Item 3.** | **QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**  |

---

**Interest Rate Risk** 

We had unrestricted cash and cash equivalents of $252.5 million and $314.0 million as of March 31, 2026 and December 31, 2025, respectively. We maintain our cash and cash equivalents in deposit accounts and money market funds with various financial institutions. Due to the short-term nature of these instruments, we believe that we do not have any material exposure to changes in the fair value of these investments as a result of changes in interest rates. Increases or declines in interest rates would be expected to augment or reduce future interest income by an insignificant amount.

We are exposed to risk related to changes in interest rates on our outstanding borrowings. Borrowings under our Credit Agreement bear interest at rates that are variable. Increases in the bank prime or SOFR rates would increase the interest rate on any future outstanding borrowings. Any debt we incur in the future may also bear interest at variable rates.

Our Notes have a fixed annual interest rate; therefore, we have no financial or economic interest exposure associated with changes in interest rates. However, the fair value of fixed rate debt instruments fluctuates when interest rates change. Additionally, the fair value of the Notes can be affected when the market price of our common stock fluctuates. We carry the Notes at principal value less unamortized issuance costs on our condensed consolidated balance sheets, and we present fair value for required disclosure purposes only.

**Foreign Currency Exchange Risk** 

Our revenues and expenses are primarily denominated in U.S. Dollars. For our foreign operations, the majority of our revenues and expenses are denominated in other currencies, such as the Canadian Dollar, Euro, British Pound, Swedish Krona, and Brazilian Real. Decreases in the relative value of the U.S. Dollar as compared to these currencies may negatively affect our revenues and other operating results as expressed in U.S. Dollars. For both the three months ended March 31, 2026 and 2025, approximately 4% of our revenues were denominated in currencies other than U.S. Dollars.

We have experienced and will continue to experience fluctuations in our net income or loss as a result of transaction gains or losses related to revaluing certain current asset and current liability balances that are denominated in currencies other than the functional currency of the entities in which they are recorded. We have historically recognized immaterial amounts of foreign currency gains and losses in each of the periods presented. We may in the future hedge selected significant transactions denominated in currencies other than the U.S. dollar as we expand our international operations and our risk grows.

**Evaluation of Disclosure Controls and Procedures**

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

Based on the evaluation of our disclosure controls and procedures, our principal executive officer and principal financial officer concluded that, as of March 31, 2026, our disclosure controls and procedures were effective at a reasonable assurance level.

**Changes in Internal Control over Financial Reporting**

There were no changes in our internal control over financial reporting during the period covered by this Quarterly Report on Form 10-Q that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**PART II---OTHER INFORMATION**

**ITEM 1. LEGAL PROCEEDINGS** 

On January 25, 2022, we filed a complaint (subsequently amended on February 9, 2022) against Avalara, Inc. ("Avalara") in the United States District Court for the Eastern District of Pennsylvania. The complaint alleges claims of unfair competition, intentional interference with contractual relations, and trade secret misappropriation against Avalara. We are seeking a permanent injunction to prevent Avalara from further interference with our contractual relations and to prohibit the disclosure in any way of our confidential, proprietary and/or trade secret information. We are also seeking monetary damages, including punitive damages and attorney's fees. As of March 31, 2026, the matter remains before the Court and trial is scheduled to commence on October 13, 2026. We believe the allegations in the complaint, once proven, are sufficient to prevail in this matter. However, the eventual outcome of the case is subject to a number of uncertainties, and therefore we cannot offer any assurance as to the ultimate impact of this case on our business and operations.

In addition to the foregoing matter, from time to time, we may be involved in various legal proceedings arising from the normal course of business activities. We are not presently a party to any litigation the outcome of which we believe, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, cash flows or financial condition.

**ITEM 1A. RISK FACTORS**

***Our cost reduction and restructuring efforts may not achieve their intended benefits and could adversely affect our profitability, financial condition, and results of operations.***

The Company has undertaken the Value Creation Plan (the "Plan") announced in April 2026. The Plan includes a reduction in force of approximately 170 employees across multiple geographies. There can be no assurance that we will achieve the anticipated benefits on the expected timeline, or at all. Implementation costs also might exceed expectations and further cost reduction measures might become necessary, resulting in additional future charges. If these efforts are not properly implemented or are unsuccessful, the Company might experience business disruptions, or our business otherwise might be adversely affected.

Restructuring activities inherently involve significant risks and uncertainties. The Plan could result in the loss of institutional knowledge and expertise, reduce morale and productivity among our remaining employees, and make it more difficult for us to attract, retain, and motivate key personnel. The Plan may also cause significant disruption to our operations, including our ability to maintain the quality and timeliness of our software solutions and customer support. Changes in our service delivery, product development, and customer success teams could adversely affect our customer relationships, our ability to meet contractual obligations, and the pace of innovation and product enhancements. The Plan could also expose the Company to claims, litigation, or regulatory proceedings related to the workforce reduction, which could be costly and time-consuming and could divert management's attention. Any of the foregoing risks could materially adversely affect our business, financial condition, and results of operations.

This document incorporates by reference various risk factors discussed in the Company's 2025 Annual Report, under the heading "Risk Factors".

There are no additional material changes to the risk factors discussed in these filings. You should carefully consider these risks, together with management's discussion and analysis of our financial condition and results of operations in conjunction with the condensed consolidated financial statements and the notes thereto included elsewhere in this Quarterly Report on Form 10-Q. If any of the events contemplated should occur, our business, results of operations, financial condition and cash flows could suffer significantly.
