Our cloud-first architecture and customer-centric approach empower companies to deliver unforgettable experiences for their B2B (business-to-business), B2C (business-to-consumer), and B2B2X (business-to-business-to-consumer) customers, making it easier for people and businesses to buy, use, and pay for the services they value most. CSG manages billions of critical customer interactions annually, and we do it with a singular focus – an obsession on our customers’ success. As a global technology leader, we aspire to envision, invent, and shape a better, more future-ready world. Specifically, our mission is focused on helping some of the world's most recognizable brands compete and win in the digital age by making it easier for their customers to do business. Every company in every industry vertical with recurring customer relationships needs to make it easier for their consumer and enterprise customers to do business with them in their customers’ preferred channel of choice. They need to make it easier for customers to identify which product or service is right for them; easier to buy, procure, provision, and pay for their goods and services; easier to communicate with or get updates from them; and easier to modify the goods/services they buy. This is exactly where CSG’s SaaS platforms come in. Industry leaders in telecom, broadband cable, media, retail, healthcare, financial services, insurance, government, and other industries leverage the power of our integrated, domain specific technology to compete and win in the digital age. Our 5,500-plus employees around the globe have made CSG a trusted technology leader and SaaS platform company to some of the biggest and most innovative brands around the world. Our corporate headquarters is located at 169 Inverness Dr W, Suite 300, Englewood, Colorado 80112, and the telephone number at that address is (303) 200-2000. Our common stock is listed on the Nasdaq Stock Market LLC (“Nasdaq”) under the symbol “CSGS”. We are a member of the S&P Small Cap 600 and Russell 2000 indices. Plan of Merger On October 29, 2025, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with NEC Corporation, a company incorporated under the laws of Japan (“NEC”) and Canvas Transaction Company, Inc., a Delaware corporation and a direct or indirect wholly owned subsidiary of NEC (“Merger Sub”). Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into CSG (the “Merger”), with CSG continuing as the surviving corporation as a wholly owned subsidiary of NEC. Per the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of CSG common stock that is issued and outstanding immediately prior to the Effective Time (other than the Cancelled Shares and Dissenting Shares, as they are defined in the Merger Agreement), will be converted into the right to receive $80.70 per share in cash (the “Merger Consideration”). Our Board of Directors (the “Board”) unanimously approved the Merger Agreement and the transactions contemplated thereby, including the Merger, and, subject to the terms of the Merger Agreement, recommended that our stockholders adopt the Merger Agreement. On January 30, 2026, at a special meeting, our stockholders adopted the Merger Agreement and approved the Merger. The closing of the Merger is expected to occur in 2026, subject to the satisfaction of customary closing conditions and required regulatory approvals. There can be no guarantee that the Merger will be completed or that, if completed, it will be exactly on the same terms as set forth in the Merger Agreement. If the Merger is consummated, CSG will become a privately held company and our common stock will be delisted from the Nasdaq and deregistered under the Exchange Act. Information about the Merger Agreement and the Merger is set forth in our Definitive Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission ("SEC") on December 16, 2025, as supplemented.
