CEO Jeffrey Eberwein buys 5,000 shares at $11.01–$11.21 on STRR; part of cluster with 4 other insiders buying in past 14 days.

Jeffrey E. Eberwein, CEO of Star Equity Holdings (STRR), executed 2 purchases totaling 5,000 shares for $56,048.80 at an average price of $11.21 on June 15–16, 2026. This transaction occurs in the context of a cluster buy pattern: 4 other insiders also purchased within the past 14 days. The stock is currently at $11.08, trading -7.6% from its 52-week high of $11.99, but up +14.2% over the past 30 days and +11.7% over 90 days. The company reported $50.1M in latest quarterly revenue with annual growth of +22.9%, yet it posted a net loss of $-3.8M and remains unprofitable on a full-year basis. Eberwein's cross-ticker track record shows 19 prior buys with an average 90-day return of -7.7% and a 0% win rate, raising questions about the quality of his buy signals in open-market transactions outside this ticker.

Significance 6

Director Mimi K Drake bought 1,000 shares of STRR at $11.65; 4 other insiders bought within 14 days amid $-3.8M net loss.

Mimi K Drake, a Director, purchased 1,000 shares at $11.65 on 2026-06-05, bringing her holdings to 44,834 shares post-transaction. This purchase is part of a cluster pattern: 4 other insiders also bought within the past 14 days, suggesting coordinated or independently-motivated insider accumulation. STRR is currently unprofitable with a full-year net income of $-3.8M despite strong revenue growth of +22.9% year-over-year and $50.1M in latest-quarter revenue. The stock has rallied +13.6% over 90 days and +13.3% over 30 days, trading near its 52-week high of $11.99. The confluence of multi-insider buying activity during a period of operational losses and elevated valuation warrants attention to whether insiders are acting on turnaround expectations or other non-public information.

Significance 4

CEO Jeffrey E. Eberwein bought 1,884 shares at $10.89, but his 5 recent STRR purchases all underperformed—0 of 5 had positive 90d returns.

Jeffrey E. Eberwein, CEO of Star Equity Holdings, Inc., purchased 1,884 shares at $10.89 on 2026-06-10, raising his holdings to 1.11M shares. This buy follows four other insider purchases within 14 days, forming a cluster pattern. However, Eberwein's timing at this ticker is concerning: his prior 5 buys at STRR all generated negative 90-day returns (ranging from -7.0% to -7.8%), with 0 of 5 well-timed at the 90-day mark. His cross-ticker track record shows 16 prior buys with an average 90d return of -5.7% and a 12.50% win rate, indicating a pattern of poorly timed purchases across multiple stocks. Against this backdrop, the company remains unprofitable (net income of $-3.8M in the latest quarter), despite 22.9% annual revenue growth, which adds fundamental risk to the apparent accumulation signal.

Jeffrey E. Eberwein, Chief Executive Officer, executed 3 separate purchases totaling 16,292 shares for $186,123.20 between June 5 and June 9, 2026, at a blended average price of $11.42.

However, Eberwein's prior trades at this ticker show a pattern of negative returns: all 5 prior buys at STRR resulted in 90-day losses ranging from -7.0% to -7.8%, with zero of those trades being well-timed. Additionally, the company remains unprofitable with net income of $-3,793,000.00 against revenue of $50,061,000.00 in the latest quarter. A cluster buy pattern is present with 4 other insiders also purchasing within the past 14 days.

Jeffrey E. Eberwein, Chief Executive Officer of Star Equity Holdings, Inc., executed 3 separate open-market purchases totaling 6,412 shares for $74,290.22 at a blended average price of $11.59 between June 2–4, 2026. His post-transaction holdings stand at 1,087,538 shares, a +0.6% increase. The stock currently trades at $11.65, near the top of its 52-week range ($1.93–$11.99), and has climbed +24.6% over the past 30 days and +15.7% over 90 days. Notably, a CLUSTER pattern shows 2 other insiders also purchased shares within the past 14 days, suggesting coordinated interest among the leadership team. At the company level, fundamentals remain challenged: the most recent quarter showed revenue of $50,061,000.00 and a net loss of $-3,793,000.00, with the company unprofitable over its full fiscal year, although annual revenue growth reached +22.9%. The CEO's prior trades at this ticker have a strong timing pattern: 4 of 5 prior buys were well-timed at the 90-day mark, with particularly strong execution on May 20 (+14.2% 90d return) and May 21 (+6.6% 90d return).

Louis A. Parks, Director, purchased 1,000 shares at $11.60 on 2026-05-29, bringing his holdings to 15,813 shares and representing a +6.8% increase in his position. His prior two purchases at STRR (2026-03-27 and 2025-09-15) both showed positive 90-day returns of +16.9% and +7.0% respectively, indicating a pattern of well-timed entries at this ticker.

However, the company posted a net loss of $-3,793,000.00 in its latest quarter despite revenue of $50,061,000.00 and was unprofitable over its most recent full fiscal year, warranting investor attention to the disconnect between insider accumulation and negative earnings.

Jeffrey E. Eberwein, Chief Executive Officer, executed 4 separate purchases totaling 16,656 shares for $195,611.52 between May 28 and June 1, 2026, at a blended average price of $11.74. The current stock price is $11.70, within 2.4% of the 52-week high of $11.99, and the stock has risen 30-day change: +23.2%. His prior 5 trades at STRR show a strong timing pattern: 4 of 5 prior buys generated positive 90-day returns. However, the company's most recent quarter shows net income of $-3,793,000.00 despite revenue of $50,061,000.00, indicating unprofitability during the latest full fiscal year. This accumulation by the CEO at a price near the 52-week high of $11.99 occurs against the backdrop of ongoing losses, creating a tension between the insider's recent purchase activity and deteriorating profitability.
