Guidewire Software has agreed to acquire hyperexponential for $1.7 billion in cash, with up to $400 million more payable if specified post-closing recurring revenue targets are met. The agreement was announced on October 27, 2026. Subject to customary regulatory and antitrust conditions, the transaction is expected to close in the second quarter of Guidewire’s fiscal 2027. The deal would bring hyperexponential’s pricing and underwriting software, including hx Renew and its hyperoperator agentic workbench, into Guidewire’s business. The platform supports decisions across more than $75 billion in annual commercial property and casualty gross written premium. At Guidewire’s Investor Day, CFO Jeff Cooper projected the acquisition would add at least 650 basis points to fiscal 2027 annual recurring revenue growth inorganically, followed by at least 150 basis points of organic ARR expansion annually from fiscal 2028. Guidewire plans to update its fiscal 2027 guidance in December 2026.
