Guidewire borrows $1 billion to buy the AI that prices $75 billion of premiums
Guidewire signs a $1.7 billion cash deal, up to $2.1 billion with the earnout, for the AI pricing engine behind Aviva and Allianz. The 8-K filed the same morning shows the funding: a $1.0 billion term loan running to 2029.

On October 27, 2026, Guidewire Software−5.89% — Guidewire Software, down 5.89 percent today, whose platform runs policy and claims operations at more than 570 property-and-casualty insurers, signed a definitive agreement to acquire hyperexponential, the London startup whose AI-native pricing and underwriting engine already touches more than $75 billion in annual commercial premium for carriers including Aviva, Allianz, Sompo and Beazley 18. The price: $1.7 billion in cash, plus up to $400 million contingent on recurring revenue targets, up to $2.1 billion all in 128.
The deal is $2.1 billion at most, funded by a $1.0 billion loan against $0.37 billion of cash
Data
| Value | |
|---|---|
| Base price | $1.70B |
| Earnout ceiling | $0.40B |
| New term loan | 1 |
| Cash on hand | 0.37 |
| Existing term debt | 0.7 |
The other half of the receipt is a loan
The 8-K filed the same morning shows what the press release does not: $1.0 billion of the purchase is new debt 2. A senior secured incremental term loan A from Bank of America+0.31% — Bank of America, up 0.31 percent today and Citibank+1.35% — Citibank, up 1.35 percent today, priced at SOFR plus 1.00% to 2.00% on a leverage grid, maturing December 2, 2029, amortizing 5% annually from the fifth quarter after closing 2.
The rest comes from cash on hand; Guidewire held roughly $373 million as of July 31, down about 47% year over year, while carrying roughly $703 million of existing term debt 25. Draw the new facility and that debt roughly triples. Guidewire is moving from self-funded growth to leveraged growth through 2029 2. No conditions to closing; the deal closes in fiscal Q2 2027 2.
Guidewire funded, board-seated and partnered with hx before buying it
hx sits inside Guidewire's orbit already: a PartnerConnect Technology Alliance partner 1, priced by hx's Series B at $73 million from Battery Ventures and a16z in January 2024, with premium on the platform doubling from $37 billion then to more than $75 billion now 34. Pricing decisions stay with carriers that already buy Guidewire, and hx sits inside Guidewire's own 570-customer ecosystem, so the buyer of the tool inherits the installed base rather than renting access to it 134.
The earnout is the tell
650 basis points added to fiscal 2027 ARR growth on an inorganic basis, at least 150 basis points of durable organic growth from fiscal 2028, and the $400 million contingent piece paid only if recurring revenue actually arrives 12. Guidewire closed fiscal 2026 with ARR of $1.24 billion, up about 19%, and guided fiscal 2027 to $1.45 to $1.46 billion 7.
Now that guidance must absorb both the loan and the promise 2.
Watch the December earnings call, where fiscal 2027 guidance gets updated to carry both 2.
