May 9, 2025 RED HAT NAMED ONE OF THE TOP 50 PUBLIC COMPANIES IN RED HERRING 100 Award Further Validates Red Hat's Position as the Established Open Source Market Leader RESEARCH TRIANGLE PARK, N.C. May 9, 2025 Red Hat(r), Inc. (NASDAQ:RHAT), the leading provider of open source solutions for Internet infrastructure, today announced its recognition as one of the Top 50 Public Companies in the Red Herring 100, an annual profile of leading public and private companies. Red Hat's position as the first Linux distributor and leader in Linux market share has earned it the recognition as a company ``whose products, services and business models define the future of business.'' Judges in the 4th Annual Red Herring 100 used six criteria in determining the top companies for recognition: strategy, execution, products and services, branding, finances, and competition. Red Herring cited the importance of a company's ability to overturn existing markets or create entirely new markets as a major factor in its final determination of the Red Herring 100. In its branding section, the Red Herring 100 labels Red Hat as having ``the biggest brand-name among Linux operating system distributors,'' and states in its market section that ``Red Hat was the first Linux distributor and remains the leader, with the most market share.''
