MARKEL GROUP INC.

Throughout the first half of 2025, the U.S. has announced new, as well as changes in, tariffs on a broad range of foreign imports. These tariffs, and any additional duties, tariffs and other trade barriers, imposed or modified by the U.S., and retaliatory or responsive countermeasures by other countries, may adversely affect the price and availability of goods for our businesses and the demand for our products. Additionally, any such measures or countermeasures may increase inflationary pressure on our insured losses and loss adjustment expenses. These impacts may be material, and our efforts to mitigate these impacts may not be successful and, even when they are successful, there may be a time lag before the impacts of these efforts are reflected in our results. See Item 1A Risk Factors in our 2024 Annual Report on Form 10-K for more discussion of these risks, including under:

•"Our results may be affected because actual insured or reinsured losses differ from our loss reserves."

•"Our investment results may be impacted by changes in interest rates, U.S. and international monetary and fiscal policies as well as broader economic conditions."

•"General economic, market or industry conditions could lead to investment losses, adverse effects on our businesses and limit our access to the capital markets."
