Guidewire Buys AI Underwriting Platform Hyperexponential in $1.7 Billion Cash Deal

Insurance News Desk: Guidewire Software has agreed to acquire London based hyperexponential for a base price of 1.7 billion dollars in cash along with as much as 400 million dollars more if specified recurring revenue targets are reached bringing the total potential value to 2.1 billion dollars.

The company confirmed the definitive agreement in its announcement on October 27 2026 noting that the deal remains subject to customary adjustments and is expected to close during the second quarter of Guidewire’s fiscal 2027.

Hyperexponential develops AI native underwriting and pricing software aimed at commercial property and casualty insurers. Its platform already supports risk assessment and pricing decisions across more than 75 billion dollars in annual commercial P and C premium for leading carriers reinsurers and managing general agents.

Guidewire which already counted hyperexponential among its PartnerConnect Technology Alliance partners said the combination will accelerate its move into agentic underwriting an approach in which AI agents work directly alongside human underwriters and actuaries to evaluate risks set prices and reach decisions on both complex specialty accounts and higher volume commercial business.

Guidewire plans to fund the transaction with 1 billion dollars in new term loan financing together with cash on hand having secured a binding commitment from Bank of America and Citibank.

The company expects the acquisition to add at least 650 basis points to its fiscal 2027 annual recurring revenue growth on an inorganic basis and then contribute at least 150 basis points to durable organic ARR growth beginning in fiscal 2028 while remaining consistent with long term margin targets.

Chief Executive Officer Mike Rosenbaum described insurance as a distinctly complex industry where the quality of risk decisions carries an immense impact on business outcomes. Hyperexponential Chief Executive Officer Amri Santhirasenan added that the combination should allow insurers to respond to submissions more quickly improve loss ratios and allocate capital more effectively.

Customers of the London firm already include major names such as Aviva, Allianz, Beazley, Markel and Cincinnati Financial underscoring the established market presence Guidewire is bringing into its broader platform.

The transaction continues Guidewire’s pattern of selective technology additions aimed at strengthening its position as a core system provider for property and casualty insurers operating in more than 40 countries.
