Oakmark Global Select Fund stated the following regarding IQVIA Holdings Inc. (NYSE:IQV) in its Q1 2026 investor letter:

“IQVIA Holdings Inc. (NYSE:IQV) was the top detractor during the quarter. The U.S.-headquartered provider of clinical research services, analytics, and solutions saw the price of its stock decline on AI-related fears despite reporting an in-line fourth quarter and 2026 outlook. Management believes the demand environment has stabilized and leading growth indicators, such as bookings and win rates, are encouraging. They expect IQVIA to be a net beneficiary of AI due to proprietary data, domain expertise, and regulatory and compliance barriers, among other factors. We continue to view IQVIA as a stable, long-cycle business that will benefit from a recovery in client spending in the coming quarters.”
