About STAR EQUITY HOLDINGS, INC.

Star Equity Holdings, Inc. is a diversified holding company listed on the U.S. Nasdaq market (NASDAQ: STRR and STRRP), with its corporate headquarters in Old Greenwich, Connecticut, United States. For French-speaking investors, the name sits in the category of a small-cap multi-business platform rather than a classic single-line industrial stock: the company combines operating businesses with an investments and asset-management arm, and it seeks to create value through acquisitions, operational improvement, and disciplined capital allocation. Star’s modern structure reflects a longer corporate history under its former name, Digirad Corporation. The company was incorporated in Delaware in 1997 and changed its name to Star Equity Holdings, Inc. effective January 1, 2021.

Building Solutions is the core industrial platform and includes three businesses: modular building manufacturing; structural wall panel and wood foundation manufacturing, including building supply distribution; and glue-laminated timber (glulam) column, beam, and truss manufacturing. Business Services operates through Hudson Talent Solutions and provides talent acquisition and workforce strategy services across the Americas, EMEA, and APAC. Energy Services focuses on the rental, sale, and repair of downhole tools used in oil and gas, geothermal, mining, and water-well markets. The Investments division manages and finances the company’s real estate assets and its positions in private and public companies. ([starequity.com](https://www.starequity.com/)) From a competitive standpoint, Star Equity should be viewed as a niche diversified industrial holding company. Its investment case is not driven by one dominant product franchise, but by the ability of management to integrate acquisitions, improve operating efficiency, and allocate capital between businesses with very different growth profiles and cyclicality. That makes the story potentially interesting, but also more complex than a pure-play manufacturer or service provider. The group’s geographic footprint is primarily U.S.-based at the operating level, while Business Services adds global service exposure. Star’s Energy Services platform, for example, is anchored in local operating hubs in Texas, Wyoming, and Utah through Alliance Drilling Tools, which Star acquired in March 2025. ADT was founded in 2009 and brought immediate scale to the group’s energy-oriented activities. ([starequity.com](https://www.starequity.com/news-releases/news-release-details/star-equity-holdings-acquires-alliance-drilling-tools)) Recent corporate developments matter materially. In 2025, Star completed the acquisition of Alliance Drilling Tools, expanding into Energy Services. Later in August 2025, the company completed a merger with Star Operating Companies, an event that management described as transformative in its 2025 results commentary. Following that transaction, the company highlighted stronger scale and reported full-year 2025 revenue of $172.2 million, up 23% year over year, with pro forma revenue of $224.7 million. In March 2026, management also pointed to improved quarterly momentum versus the prior year, while the corporate website continued to list a cash dividend on the Series A preferred stock. For equity investors, the key question is whether Star can turn its multi-division structure into a more coherent, higher-margin platform over time.
