↑ 4%Rocket Software to acquire Vertica analytics database platform. Rocket Software has agreed to acquire Vertica, an enterprise-grade analytics database platform, from OpenText. Vertica's technology is designed to help enterprises drive better business outcomes while balancing cloud innovation with regulatory compliance, data sovereignty, performance and cost requirements. Adding Vertica to its portfolio will allow Rocket to extend its capabilities to support the modernization of high-performance analytics, data and AI, particularly for customers with demanding IT environments, officials said. Rocket Software has experience running mission-critical data platforms, including Rocket MultiValue databases that power daily retail and healthcare operations, Rocket Model 204 for high-volume mainframe transaction processing, and Rocket ContentEdge for governance-first, AI-enabled large-scale content modernization. The Vertica acquisition will accelerate Rocket Software's ability to help customers not only modernize core systems and data but also run next-generation analytics and GenAI directly on that trusted data. Vertica supports cloud, on-premises and hybrid deployments, combined with AI/ML capabilities, officials said. "The surge in AI investment has heightened both the importance and the difficulty of turning data into real business value," said Milan Shetti, president and CEO of Rocket Software. "With Vertica, we're addressing the next wave of modernization challenges: transforming data warehouses, repatriating analytics workloads and enabling AI-driven decision-making so customers can handle their most data-intensive workloads and accelerate modernization." Rocket intends to fund the acquisition with cash from its balance sheet. The transaction is expected to close by mid-year and is subject to applicable regulatory approvals and other customary closing conditions.

Thomas Jenkins, OpenText Executive Chairman of the Board and Chief Strategy Officer. "By rationalizing non-core assets, we are strengthening the portfolio, reinforcing our capital allocation framework, and positioning OpenText to accelerate long-term growth and shareholder value."
