FOSTER CITY, Calif. -- May 13, 2013

Guidewire Software, Inc. (NYSE: GWRE), a provider of software products for
Property/Casualty (P/C) insurers, today announced it has acquired Millbrook,
Inc., a provider of data management and business intelligence (BI) solutions
for P/C insurers. The addition of Millbrook’s technology will enable Guidewire
customers to accelerate replacement of their legacy core systems and to
improve management of operational data in their policy, billing, and claims
functions.

Guidewire provides a proven software suite enabling P/C insurers to replace
legacy core system environments that constrain their business ambitions. A
modern data management infrastructure can enhance the benefits while reducing
the cost, risk, and duration of legacy system replacement initiatives. To this
end, the Millbrook team has invested 16 years developing data models and
solutions for data management and business intelligence optimized for P/C
insurance.

“We welcome the Millbrook team and look forward to their contributions to our
mission of enabling P/C insurers to transform their businesses and improve
service to their policyholders,” said Marcus Ryu, chief executive officer,
Guidewire Software. “The Millbrook team shares our sole focus on the P/C
insurance industry and our foremost commitment to customer success.”

“We are very excited about this acquisition from a solution perspective,” said
Neil Betteridge, vice president, Strategy, Guidewire Software. “Data
challenges are often viewed as significant inhibitors to legacy system
replacement and business transformation. Providing data management and
business intelligence capabilities is an ideal complement to the core systems
we already provide.”

“I am proud of our track record and would like to thank the loyal Millbrook
customers that supported our success as well as our dedicated employees who
have an intimate understanding of P/C data management. We are excited to bring
our technology and expertise to Guidewire,” said John Search, co-founder,
Millbrook and senior consulting director, Guidewire Software. “Our past work
with mutual customers has shown our ability to deliver significant benefits
using both companies’ products together.”

Guidewire does not expect the acquisition of Millbrook will have a material
impact on revenue or non-GAAP profitability in the fourth quarter or full year
fiscal 2013. The company will announce its third quarter financial results,
along with its overall guidance for the fourth quarter and full year fiscal
2013 on May 28, 2013. A separate press release with dial-in information will
be issued at a later date.
