Star Equity Holdings, Inc.: what insiders have been doing
Star Equity Holdings, Inc. is a Industry company. Its directors and officers file their transactions with SEC (Form 4). From 18 October 2025 to 18 October 2026, the disclosure feed for Star Equity Holdings, Inc. logged 47 filings by 9 insiders.
The record shows 4 purchases on the open market worth €2.7M, made by 3 insiders, against 15 sales worth €326k by 1 insider. The net balance comes to €2.3M on the buying side. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Among those who bought: 2 chief executives and 1 senior executive. At €2.6M, the purchase published on 10 December 2025 by Eberwein Jeffrey E. is the largest of the period.
Across the 5,816 companies tracked on its exchange, the median is 19 filings; at 47 filings, this issuer sits above that mark. Since 2025, the database holds 9 purchases and 15 sales by insiders of the company.
In the case of 1 purchase, another manager of the company was buying within the same 30 days. Purchases made close together by different insiders form what is called a cluster. The latest purchase dates back some time: it was published 79 days ago, on 31 July 2026. The median gap between a trade and its publication by SEC (Form 4) is 2 days. Section 16 rules allow two business days to file each Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.
Elsewhere in the same sector, our signals recently picked up insider purchases at Tennant Co and Butler National Corp. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.

About Star Equity Holdings, Inc.
Star Equity Holdings, Inc. is a United States-listed company trading on the NASDAQ under the symbols STRR and STRRP. For European investors, it should be viewed as a small-cap diversified holding company with an industrial tilt and a capital-allocation-driven strategy. The company is headquartered in Old Greenwich, Connecticut, United States. It was incorporated in Delaware in 1997 and operated for many years under the name Digirad Corporation before adopting its current name, reflecting a broader evolution in business mix and corporate strategy.
Star Equity has historically been built as a multi-division platform, but in recent years it has moved toward a more explicit holding-company model. The group’s management emphasizes capital allocation, strategic transactions, mergers and acquisitions, and portfolio optimization as core levers of value creation. That makes the stock relevant for investors who want exposure to a small-cap special situation rather than a pure-play operating company. The structure also gives management flexibility to pursue add-on acquisitions, divestitures, financings, or share repurchases depending on market conditions.

On the operating side, the company’s recent footprint is centered on building-related solutions and specialized industrial services. In 2025, Star Equity announced the acquisition of Alliance Drilling Tools, LLC, a Wyoming- and Texas-based supplier and repairer of drilling equipment serving the oil and gas, geothermal, mining, and water-well industries. That transaction broadened the company’s industrial exposure and added a niche business with end-market diversification. The company’s 2026 results also referenced a Building Solutions segment, which generated revenue and gross profit in the latest quarter, underlining the importance of construction-adjacent activities in the current mix.
From a competitive standpoint, Star Equity does not compete as a large-scale integrated industrial group. Instead, it occupies a niche position, using smaller acquisitions and active portfolio management to improve scale and profitability over time. This can be attractive if management executes well, particularly because the group has also signaled willingness to repurchase shares when it believes valuation is compelling. At the same time, the model carries the usual risks of a small holding company: acquisition integration risk, cyclicality in construction and industrial end markets, and potential earnings volatility.
Recent milestones have been important. In 2025, the company completed a transformative merger that reshaped its platform, then announced the ADT acquisition and a new share repurchase authorization. By early 2026, Star Equity continued to present itself as a diversified NASDAQ-listed holding company focused on growth through acquisitions, portfolio actions, and long-term shareholder value creation.
