Item 2.02. Results of Operations and Financial Condition.

On November 3, 2025, Vertex, Inc. (the “Company”) issued a press release announcing its financial results for the third quarter ended September 30, 2025 and the adoption of its first-ever stock repurchase program. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The information contained in this Item 2.02, including Exhibit 99.1 hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing made by the Company under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filings, unless expressly incorporated by specific reference in such filing.

Item 8.01. Other Events.

On October 30, 2025, the Company’s Board of Directors authorized a stock repurchase program for up to $150 million 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 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.
