BBH Select Series – Mid Cap Fund stated the following regarding Guidewire Software, Inc. (NYSE:GWRE) in its fourth quarter 2025 investor letter:
“The Fund’s largest detractors to performance in the quarter were Shift4 Payments Inc. (Shift4), and Guidewire Software, Inc. (NYSE:GWRE). Both had strong fundamental performance but declined on increased negative sentiment for payments and software sectors, respectively. Guidewire declined -12.6% during the quarter, ending with a weight of 5.5%. Guidewire is the leading provider of core systems software to the property and casualty (P&C) insurance industry. Guidewire reported another strong quarter with annual recurring revenue (ARR), revenue, and operating income all above guidance and expectations. ARR growth accelerated to +21% in constant currency, the company’s fastest growth since starting to report the metric in 2020, highlighting the sustained drivers of demand. Subscription revenue growth of +36% delivered 82% incremental margins as Guidewire continues to demonstrate excellent cost efficiency as well. Full-year guidance was raised for all metrics, while Guidewire also introduced two new modules in PricingCenter and UnderwritingCenter, which will further increase the opportunity set for customers. The company’s Investor Day and User Conference mid-fourth quarter reinforced Guidewire’s industry leadership and attractive opportunity in the years ahead. Notwithstanding these strong fundamentals, the software sector was broadly out of favor on concerns that AI will commoditize software coding and lower barriers to entry for enterprise software. This is difficult to disprove in the short term, but our view is that, as a market-leading incumbent with deep vertical domain expertise, Guide wire will be a beneficiary of AI as it drives increased adoption of its cloud-based core systems software, lowers internal development costs, and facilitates faster incremental product introductions.”
