Recently Closed Two Accretive Bolt-On Acquisitions

OLD GREENWICH, CT - November 11, 2026 - Star Equity Holdings, Inc. (Nasdaq: STRR and STRRP) ("Star" or the "Company"), a diversified holding company, announced today financial results for the third quarter ended September 30, 2026.

2026 Third Quarter Summary

•Revenue of $53.9 million increased 12.4% from the third quarter of 2025.

•Gross profit of $23.2 million increased 12.6% from the third quarter of 2025.

•Net loss attributable to common shareholders was $2.2 million, or $0.60 per diluted share, compared to net loss attributable to common shareholders of $1.8 million, or $0.56 per diluted share, for the third quarter of 2025. Adjusted net loss per diluted share (non-GAAP measure)* was $0.26 compared to adjusted net income per diluted share of $0.08 in the third quarter of 2025. Pro forma adjusted net income per diluted share was $0.18 in the third quarter of 2025.

•Adjusted EBITDA (non-GAAP measure)* increased to $1.5 million versus adjusted EBITDA of $1.3 million in the third quarter of 2025; pro forma adjusted EBITDA was $3.1 million in the third quarter of 2025.

•Total cash including restricted cash was $7.8 million at September 30, 2026.

Jeff Eberwein, CEO of Star, noted, “In the third quarter, Energy Services gross profit and adjusted EBITDA increased on a pro forma basis, and in October we expanded the division by acquiring a machine shop in Vernal, Utah adding in-house machining, repair, and rebuild capabilities to our existing operation there. In Building Solutions, results were below the prior year quarter on a pro forma basis, reflecting continued softness in the residential and multifamily new construction markets. In addition, a large KBS Builders project, for which we received a non-refundable deposit, has shifted from 2026 to 2027. Despite these headwinds, the division’s backlog, which excludes this project, grew to $11.4 million from $10.6 million at the end of the second quarter and new orders were above $17.0 million for the second quarter in a row.”

Jake Zabkowicz, Global CEO of Hudson Talent Solutions (“HTS”), added, “Despite continued macroeconomic uncertainty and pressure in the professional talent market, HTS limited its year-over-year gross profit decline to 2%, supported by 4% gross profit growth in the Americas. In the third quarter, we invested $1.4 million in digital offerings, expansion into new geographies, and other growth initiatives, while increasing our use of agentic AI and automation to enhance recruiter productivity and candidate matching. In November, we acquired Cornerstone RPO, which bolsters our presence in the U.S., the world’s largest RPO market, and adds established enterprise client relationships and experienced U.S. sales leadership. Additionally, we moved up to No. 3 globally, a significant improvement versus history,

in HRO Today’s 2026 Global RPO Baker’s Dozen Customer Satisfaction Ratings. We believe this recognition and our investments in growth initiatives position us well to win new business going forward.”

Mr. Eberwein concluded, “In the third quarter, we generated $0.9 million of cash flow from operations and repurchased approximately $0.3 million of our common stock. We remain focused on disciplined execution, rigorous cost management, and returns‑driven capital allocation. We continue to evaluate M&A opportunities across all three operating divisions while also working to make progress on monetizing our non-cash-generating assets including two real estate holdings where we expect to receive gross proceeds of over $9.0 million from two sale-leaseback transactions. We believe we are well positioned to improve profitability in 2027 and create significant value for our stockholders over the long term.”

* The Company provides non-GAAP measures as a supplement to financial results based on accounting principles generally accepted in the United States ("GAAP"). Adjusted EBITDA, EBITDA, adjusted net income or loss, and adjusted net income or loss per diluted share are defined in the division / segment tables at the end of this release and a reconciliation of such non-GAAP measures to the most directly comparable GAAP measures is included within such division / segment tables.

In the third quarter of 2026, the Company's corporate costs were $1.8 million, up from $1.2 million in the prior year quarter, but down $0.8 million on a PF basis.

The Company ended the third quarter of 2026 with $7.8 million in cash, including $1.6 million in restricted cash.

NOL Carryforward

As of December 31, 2025, Star had $215 million of usable net operating losses (“NOL”) in the U.S., which the Company considers to be a very valuable asset for its stockholders. In order to protect the value of the NOL for all stockholders, the Company has a rights agreement and charter amendment in place that limit beneficial ownership of Star common stock to 4.99%. Stockholders who wish to own more than 4.99% of Star common stock, or who already own more than 4.99% of Star common stock and wish to buy more, may only acquire additional shares with the Board’s prior written approval.
