RadNet, Inc. (RDNT)

In November 2025, Harbor Capital sold a significant amount of RadNet shares. In March 2026, RadNet reported record revenue for Q4 and full-year 2025, but the stock price fell due to concerns about the Gleamer acquisition and a short-seller report. In April 2026, RadNet launched a joint venture in Boise, Idaho, and Barclays cut its price target on RadNet. RadNet is scheduled to report its Q1 2026 earnings on May 11, 2026.

Demand for radiology services can exhibit seasonality, with increased demand in the final quarter of the year and during the flu season. The holiday season may also contribute to an increase in trauma-related imaging cases. The demand for medical imaging is projected to continue growing due to an aging population and advancements in imaging technologies.

RadNet, Inc. is a national provider of outpatient diagnostic imaging services and advanced digital health solutions, operating through its Imaging Center and Digital Health segments. The Imaging Center segment offers a range of diagnostic imaging services, while the Digital Health segment develops and deploys AI-powered clinical applications to enhance medical image interpretation and patient outcomes.

RadNet has a significant geographic presence across multiple U.S. states, including Arizona, California, Delaware, Florida, Maryland, New Jersey, New York, and Texas. The company has expanded into the Midwest with acquisitions in Indianapolis and established a joint venture in Boise, Idaho. RadNet's DeepHealth division extends its AI and informatics offerings to markets across the United Kingdom and Europe.

RadNet generally maintains a strong reputation as a national leader in outpatient diagnostic imaging, benefiting from secular tailwinds and strategic AI investments. However, a short-seller report raised questions about RadNet's "same-center growth methodology," leading to the removal of "same-center revenue" language from its 2025 10-K filing, which created an "optics issue."

Institutional investors hold a dominant stake in RadNet, Inc., owning approximately 77.90% to 92% of outstanding shares. Major institutional owners include BlackRock Inc., The Vanguard Group, Neuberger Berman Group LLC, and State Street Corporation. Howard G. Berger, the company's Chairman and CEO, is the largest individual shareholder.
