Guidewire Acquires hyperexponential for $1.7 Billion

The headline terms are simple. Guidewire will acquire all of hyperexponential for a base purchase price of $1.7 billion in cash. According to the current report on Form 8-K (opens in a new tab) that Guidewire filed with the U.S. Securities and Exchange Commission, the base price is subject to customary adjustments for working capital, cash, indebtedness and retention amounts. Guidewire’s investor presentation adds that the approximately $1.7 billion is inclusive of an employee retention pool, so part of the headline figure is set aside to keep the hx team in place after closing.

On top of the base price, the sellers can earn up to $400 million of contingent consideration. Guidewire’s filing ties that amount to the achievement of recurring revenue targets, which aligns a meaningful slice of the price with hx continuing to win and expand customers inside the combined company. Taken together, the two components set the full potential value of the deal, shown as a calculated figure in the key numbers above.

The agreement is not subject to a financing condition. Guidewire has lined up committed debt and will fund the rest from its balance sheet, as set out in the financing section below. The 8-K also states that the transaction is expected to close in the second quarter of Guidewire’s fiscal 2027, which ends on 31 January 2027, and that a copy of the purchase agreement will be filed with Guidewire’s quarterly report for the period ending 31 October 2026.

Centerview and J.P. Morgan lead the advisory teams

Centerview Partners LLC is serving as exclusive financial advisor to Guidewire, and Latham & Watkins LLP as its legal counsel. On the other side, J.P. Morgan is exclusive financial advisor to hyperexponential, and Wilson Sonsini Goodrich & Rosati (UK) LLP is its legal counsel. BofA Securities is acting as a lead arranger on the debt package that funds the deal.

For Guidewire shareholders, the structure is all cash, so no new shares are issued and existing holders keep their full ownership of the enlarged business. For hx’s investors and staff, the mix of an upfront cash price, a retention pool and a revenue-linked earn-out rewards both the value already built and the growth the team expects to deliver as part of Guidewire.

hyperexponential (opens in a new tab) builds software for the moment an underwriter decides whether to take on a commercial risk and what to charge for it. In its own words, hx helps carriers write more business at a better loss ratio. The company says leading global insurers rely on it for underwriting decisions across more than $75 billion in annual commercial property and casualty premium. Its named customers are Aviva, Allianz, Sompo, Beazley, Markel, HDI, Cincinnati Financial, Convex and Bowhead, a list that spans European composites, Lloyd’s and London Market specialists and U.S. commercial carriers.

The product is built for actuaries and pricing teams. Instead of keeping pricing logic in spreadsheets and static rating tables, hx lets those teams write, test and deploy pricing models in code, then put them in front of underwriters inside a structured workflow. Guidewire’s investor presentation breaks the platform into four layers: underwriting workflows, a pricing and rating engine, underwriting decisioning, and hyperoperator, the agentic automation layer that handles routine steps such as gathering submission data so underwriters can concentrate on judgement.

That focus matters because commercial insurance is a high-touch market. Large and specialty risks are often priced one at a time, from submissions that arrive as emails, spreadsheets and broker documents. Every hour saved between submission and quote helps an insurer respond first, and every improvement in model quality helps it choose better risks. hx positions its platform precisely there, which is why its customers include so many carriers that compete on underwriting skill.

A London Market base with reach into U.S. commercial lines

hx is headquartered in London and has a strong presence in the United Kingdom and Europe. Guidewire’s presentation highlights the reach this gives the combined company, from the Lloyd’s and London Market specialty segment to U.S. commercial lines. Guidewire’s investor materials put the hx team at roughly 300 people, all of whom are expected to join Guidewire, supported by the retention pool included in the purchase price.

The two companies are not starting from zero. As a PartnerConnect Technology Alliance Partner, hx has already built integrations that let its pricing engine work alongside Guidewire’s PolicyCenter and other core applications. Bringing the product in-house turns that partnership into a single offering, which Guidewire says will let insurers deploy pricing and underwriting decisions directly inside the platform that already runs their policies and claims.

Guidewire is one of the most established software companies in property and casualty insurance. According to its announcement, more than 570 insurers in 44 countries, from new ventures to the largest and most complex carriers, rely on its platform, and it has completed more than 1,700 implementation projects. Its products cover the full insurance lifecycle: policy administration in PolicyCenter, billing in BillingCenter, claims in ClaimCenter, along with data, analytics and digital engagement tools delivered through Guidewire Cloud.

What the platform has not owned until now is the pricing and underwriting decision itself. Insurers running Guidewire typically plug in a separate rating engine or keep pricing models in actuarial tools outside the core system. The investor presentation frames the deal as uniting the system of record with decision infrastructure, so that the models that choose and price risks sit directly alongside the systems that issue policies and pay claims. Guidewire says this will let carriers move from model to market faster and with less integration work.

Artificial intelligence is the second pillar of the case. Guidewire’s announcement cites a Celent report, AI Trends Across the Insurance Value Chain: P&C Edition - North America, which finds that AI-driven reductions in time-to-quote are among the factors having a significant effect on P&C insurer revenue. hx’s hyperoperator layer applies agentic automation to underwriting, and Guidewire plans to combine it with its own work on agentic claims, giving insurers AI assistance on both sides of the policy lifecycle.

Three markets sized at about $30 billion each

Guidewire’s presentation sets out three addressable opportunities for the combined company: core systems, agentic claims and agentic underwriting, each sized at roughly $30 billion. Guidewire frames the underwriting opportunity as approximately 1% of direct written premium, which links the size of the opportunity to the volume of insurance written around the world. Adding hx gives Guidewire a leading product in the third of those markets and a team that already sells into it.

Geography rounds out the case. Guidewire’s customer base is weighted toward North America, while hx brings deep relationships in the United Kingdom, Europe and the London Market. The presentation highlights growth in both directions: hx’s pricing engine offered to Guidewire’s large base of carriers, and Guidewire’s core platform offered to hx’s specialty and commercial customers.

Guidewire has given investors two numbers to track. In fiscal 2027, the year that runs to 31 July 2027, it expects the acquisition to add approximately 650 basis points of inorganic growth to annual recurring revenue. From fiscal 2028 onward, it expects hx to contribute at least 150 basis points of additional organic ARR growth each year, as the pricing engine is sold across Guidewire’s customer base.

To put those figures in context, Guidewire’s fiscal 2026 results (opens in a new tab), published on 3 September 2026, showed ARR of $1,242 million on a constant-currency basis, up 19% from $1,041 million a year earlier, and $1,237 million at current exchange rates. A 650 basis point contribution on a base of that size means hx joins Guidewire as a substantial recurring revenue business with established customers.

The broader picture at Guidewire is strong. Fiscal 2026 total revenue rose 23%, fully ramped ARR reached $1,578 million, up 22%, and cash flow from operations was about 26% of revenue. In its results, Guidewire’s chief financial officer, Jeff Cooper, pointed to record sales activity and the lowest ARR gross attrition in the company’s history. During the year Guidewire also repurchased 4,085,350 shares at an average price of $148.41, about $606.3 million in total, which shows how much cash the business generates.

Guidewire said the transaction does not change the first-quarter fiscal 2027 guidance it issued on 3 September 2026. It plans to give a full update to its fiscal 2027 outlook, including the effect of hx, in December 2026, when it reports first-quarter results.

Bank of America and Citi commit $1.0 billion of new debt

Guidewire will pay for the acquisition with a mix of new debt and existing cash. According to the 8-K, it has obtained commitments from Bank of America and Citi for a $1.0 billion incremental senior secured Term Loan A under its existing credit agreement dated 2 December 2024, with BofA Securities among the arrangers. The rest of the price will come from cash on Guidewire’s balance sheet. The term loan covers the majority of the base price, and Guidewire’s strong cash generation funds the remainder.

Because the financing is committed, the agreement carries no financing condition. Guidewire expects to complete the transaction in the second quarter of its fiscal 2027, which ends on 31 January 2027. Once the deal closes, hx’s pricing and underwriting platform and its team become part of Guidewire, and the earn-out period for the contingent consideration begins.

Guidewire has signalled how it plans to take hx to market. The investor presentation describes deploying hx’s decision infrastructure alongside Guidewire’s core applications, so that existing Guidewire customers can add pricing and underwriting capabilities without a separate integration project. hx customers that run other core systems will continue to be served, and the presentation highlights the opportunity to bring Guidewire’s platform to those carriers over time.

For customers, the immediate message is continuity. hx’s platform keeps running for the insurers that already price business on it, and the retention pool built into the purchase price is designed to keep the people who built it. For Guidewire’s customers at Connections, the announcement points to a roadmap in which underwriting, pricing, policy, billing and claims sit on one connected insurance platform.
