Guidewire plans up to $2.1 billion acquisition of AI underwriting platform hyperexponential
Guidewire signed a definitive agreement to acquire London-based hyperexponential for $1.7 billion in cash, plus up to $400 million in contingent consideration linked to recurring-revenue targets. Hyperexponential develops AI-native pricing and underwriting software for commercial property and casualty insurance and says its platform supports decisions covering more than $75 billion in annual premium. Guidewire expects the acquisition to accelerate revenue growth and position the combined company around agentic underwriting, where AI tools assist underwriters and actuaries with triage, risk assessment, pricing and portfolio decisions. The transaction is expected to close in Guidewire's second fiscal quarter of 2027 and will be funded with a new $1 billion term loan plus cash. The companies have not announced a workforce-reduction plan, and Guidewire describes the deal primarily as a product, talent and growth expansion.
