Results of Operations and Financial Condition.\n\nThe following information is furnished pursuant to Item 2.02 (Results of Operations and Financial Condition). This information shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.\n\n \n\nOn February 4, 2026, CSG Systems International, Inc. (“CSG”) issued a press release relating to the results of its operations for the quarter and year ended December 31, 2025. A copy of such press release is attached to this Form 8-K as Exhibit 99.1 and hereby incorporated by reference.\n\n \n\nIn the attached press release, CSG makes reference to non-GAAP financial measures. Non-GAAP financial measures are not measures of performance under GAAP, and therefore should not be considered in isolation or as a substitute for GAAP financial information. There are limitations with the use of non-GAAP financial measures since they are not based on any comprehensive set of accounting rules or principles, and the way in which CSG calculates non-GAAP financial measures may differ from the way in which other companies calculate similar non-GAAP financial measures. A more detailed discussion of CSG’s use of non-GAAP financial measures, to include reconciliations of the non-GAAP financial measures to the comparable GAAP financial measures, is contained in the attached press release and is posted to the Company’s website at www.csgi.com.\n\n9.01.
