The deal, a 21 percent premium over Wednesday's closing price of Hyperion's shares of $42.84, will thrust Oracle deeper into competition with long-time BI market leaders Business Objects (Quote) and Cognos (Quote).
The acquisition, which Oracle expects to close in April, will also give the software giant more leverage against applications giant SAP (Quote).
Oracle President Chuck Phillips said in a statement that thousands of SAP customers rely on Hyperion's software for financial consolidation, analysis and reporting.
Should the deal be consummated, Phillips said Hyperion software will be the "lens through which SAP's most important customers view and analyze their underlying SAP ERP data."
"The acquisition of Hyperion makes Oracle the category leader in the high growth enterprise performance management market," Oracle CEO Larry Ellison said in a statement.
"Hyperion's EPM software coupled with Oracle's Business Intelligence (BI) tools and analytic applications form an end-to-end performance management system that includes planning, budgeting, consolidation, operational analytics and compliance reporting."
