**Vertex Announces Fourth Quarter and Full Year 2025 Financial Results** 

KING OF PRUSSIA, PA – February 11, 2026: Vertex, Inc. (NASDAQ: VERX) ("Vertex" or the "Company"), a leading global provider of indirect tax solutions, today announced financial results for its fourth quarter and full year ended December 31, 2025.

"In 2025, Vertex delivered double-digit revenue growth and meaningful profitability improvements while making important investments in the future," said Christopher Young, President and Chief Executive Officer of Vertex. "We sustained our market position as the leading provider of indirect tax solutions to the enterprise and continued to onboard new customers at a healthy pace. In addition, our e-invoicing business enjoyed accelerating growth in its first full year, while setting the stage for upcoming mandates in key European economies."

Mr. Young continued, "Looking forward, I believe Vertex has a significant opportunity to accelerate revenue growth and improve profitability. We have near-term growth tailwinds including upcoming e-invoicing mandates in France and Germany, the two largest economies in Europe. In addition, Vertex is well-positioned to help tax departments improve their workflows with Artificial Intelligence. As an example, our new AI-driven Smart Categorization offering has delivered early traction, with several marquee wins with our enterprise customers. I am working closely with our teams as we execute on these opportunities, which I believe will extend Vertex's leadership position, deliver sustainable and accelerating growth, and increase shareholder value."

Definitions of certain key business metrics and the non-GAAP financial measures used in this press release and reconciliations of such measures to the most directly comparable GAAP financial measures are included below under the headings "Definitions of Certain Key Business Metrics" and "Use and Reconciliation of Non-GAAP Financial Measures."

**Financial Outlook** 

For the first quarter of 2026, the Company currently expects:

● Revenues of $193.5 million to $196.5 million;

● Adjusted EBITDA of $40.5 million to $43.5 million.

For the full-year 2026, the Company currently expects:

● Revenues of $823.5 million to $831.5 million;

● Cloud revenue growth of 25 percent; and

● Adjusted EBITDA of $188.0 million to $192.0 million.

John Schwab, Chief Financial Officer added, "Our guidance for 2026 reflects continued double-digit revenue growth along with improving profit margins. Reflecting our confidence in the business, in the fourth quarter of 2025, the Company repurchased approximately $10 million of shares of Class A common stock under our $150 million buyback authorization."

The Company is unable to reconcile forward-looking Adjusted EBITDA to net income (loss), the most directly comparable GAAP financial measure, without unreasonable efforts because the Company is currently unable to predict with a reasonable degree of certainty the type and extent of certain items that would be expected to impact net income (loss) for these periods but would not impact Adjusted EBITDA. Such items may include stock-based compensation expense, depreciation and amortization of capitalized software costs and acquired intangible assets, severance expense, acquisition contingent consideration, changes in the fair value of acquisition contingent earn-outs, amortization of cloud computing implementation costs in general and administrative expense, transaction costs, and other items. The unavailable information could have a significant impact on the Company's net income (loss). The foregoing forward-looking statements reflect the Company's expectations as of today's date. Given the number of risk factors, uncertainties and assumptions discussed below, actual results may differ materially. The Company does not intend to update its financial outlook until its next quarterly results announcement.

Important disclosures in this earnings release about and reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures are provided below under "Use and Reconciliation of Non-GAAP Financial Measures."

**Conference Call and Webcast Information**

**Forward Looking Statements**

All forward-looking statements reflect our beliefs and assumptions only as of the date of this press release. We undertake no obligation to update forward-looking statements to reflect future events or circumstances.

------

**Definitions of Certain Key Business Metrics** 

***Annual Recurring Revenue ("ARR")***

We derive the vast majority of our revenues from recurring software subscriptions. We believe ARR provides us with visibility to our projected software subscription revenues in order to evaluate the health of our business. Because we recognize subscription revenues 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 revenues ("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 direct customers with MRR at the end of the last month of the measurement period. AARPC represents average annual revenue per direct customer and is calculated by dividing ARR by the number of software subscription direct customers at the end of the respective period.

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

We believe that our NRR provides insight into our ability to retain and grow revenues from our direct 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 direct customers who were part of our customer base at the beginning of the reporting period. Our NRR calculation takes into account any revenues lost from departing direct 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.

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

We believe our GRR provides insight into and demonstrates to investors our ability to retain revenues from our existing direct customers. Our GRR refers to how much of our MRR we retain each month after reduction for the effects of revenues lost from departing direct 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.

***Customer Count***

The following table shows Vertex's direct customers, as well as indirect small business customers sold and serviced through the Company's one-to-many channel strategy.

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

In addition to our results determined in accordance with accounting principles generally accepted in the U.S. ("GAAP") and key business metrics described above, we have calculated 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, non-GAAP net income, non-GAAP diluted EPS, Adjusted EBITDA, Adjusted EBITDA margin, free cash flow and free cash flow margin, 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.

Management uses 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 and 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, and should be read in conjunction with the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on February 27, 2025, and our Annual Report on Form 10-K for the year ended December 31, 2025, to be filed with the SEC.

We calculate these non-GAAP financial measures as follows:

● 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 and severance expense included in general and administrative expense for the respective periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● 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 included in cost of subscription revenues, amortization of acquired intangible assets included in selling and marketing expense, amortization of cloud computing implementation costs in general and administrative expense, severan ce expense, acquisition contingent consideration, changes in the fair value of acquisition contingent earn-outs, and transaction costs , included in GAAP loss or income from operations for the respect ive periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Non-GAAP net income is determined by adding back to GAAP net income or loss the income tax benefit or expense, stock-based compensation expense, depreciation and amortization of capitalized software and acquired intangible assets included in cost of subscription revenues, amortization of acquired intangible assets included in selling and marketing expense, amortization of cloud computing implementation costs in general and administrative expense, severance expense, acquisition contingent consideration, adjustments to the settlement

value of deferred purchase commitment liabilities recorded as interest expense, changes in the fair value of acquisition contingent earn-outs, and transaction costs, included in GAAP net income or loss 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%.

● Non-GAAP net income per diluted share of Class A and Class B common stock ("Non-GAAP diluted EPS") is determined by dividing non-GAAP net income by the weighted average shares outstanding of all classes of common stock, inclusive of the impact of dilutive common stock equivalents to purchase such common stock, including stock options, restricted stock awards, restricted stock units and employee stock purchase plan shares. Additionally, the dilutive effect of shares issuable upon conversion of the senior convertible notes is included in the calculation of Non-GAAP diluted EPS by application of the if-converted method.

● Adjusted EBITDA is determined by adding back to GAAP net income or loss the net interest income or expense (including adjustments to the settlement value of deferred purchase commitment liabilities), income tax expense or benefit, depreciation and amortization of property and equipment, depreciation and amortization of capitalized software and acquired intangible assets included in cost of subscription revenues, amortization of acquired intangible assets included in selling and marketing expense, amortization of cloud computing implementation costs in general and administrative expe nse, stock-based compensation expense, severance expense, acquisition contingent consideration, changes in the fair value of acquisition contingent earn-outs, and transaction costs, included in GAAP net income or loss for the respective periods.

● Adjusted EBITDA margin is determined by dividing Adjusted EBITDA by total revenues for the respective periods.

● Free cash flow is determined by adjusting net cash provided by (used in) operating activities by purchases of property and equipment and capitalized software additions for the respective periods.

● Free cash flow margin is determined by dividing free cash flow by total revenues for the respective periods.

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.

In periods when the impact is anti-dilutive, there is no add-back of interest expense or additional dilutive shares related to the notes. |
