Significant New Business Wins and Contract Renewals

Realized Merger Synergies of $2.6 Million ⁽¹⁾

OLD GREENWICH, Conn., May 11, 2026 (GLOBE NEWSWIRE) -- Star Equity Holdings, Inc. (NASDAQ:STRR) ("Star" or the "Company"), a diversified holding company, announced today financial results for the first quarter ended March 31, 2026.

2026 First Quarter Summary

Revenue of $50.1 million increased 57.1% from the first quarter of 2025.
Gross profit $20.6 million increased 25.4% from the first quarter of 2025.
Net loss attributable to common shareholders was $4.4 million, or $1.17 per diluted share, compared to net loss attributable to common shareholders of $1.8 million, or $0.59 per diluted share, for the first quarter of 2025. Adjusted net loss per diluted share (non-GAAP measure)* was $0.99 compared to adjusted net loss per diluted share of $0.38 in the first quarter of 2025. Pro forma adjusted net loss per diluted share was $0.22 in the first quarter of 2025.
Adjusted EBITDA loss (non-GAAP measure)* increased to $1.6 million versus adjusted EBITDA loss of $0.7 million in the first quarter of 2025; pro forma adjusted EBITDA loss was $1.2 million in the first quarter of 2025.
Total cash including restricted cash was $10.3 million at March 31, 2026.

Jeff Eberwein, CEO of Star, noted, "The first quarter is almost always our weakest quarter of the year and in this year's first quarter, startup delays for new projects and broader macroeconomic conditions caused our Building Solutions and Business Services divisions to perform worse than expected. Our Energy Services division, however, maintained solid momentum. We believe our focus on operational and cost improvements and continued investments in growth and innovation are strengthening our competitive position and will drive significantly improved results as the year progresses."

Jake Zabkowicz, Global CEO of Hudson Talent Solutions ("HTS"), added, "Gross profit increased 6.4% at HTS year-over-year, reflecting steady improvement despite continued macroeconomic uncertainty and sustained pressure in the talent market. We have maintained a strong focus on innovation and operational efficiency, including the expanded deployment of agentic AI solutions to enhance recruiter productivity, improve candidate matching, and deliver greater value to clients. These efforts are helping our ability to navigate the current environment while positioning us to capitalize on improving market conditions in the future. As an example, new business activity and contract renewals with legacy clients accelerated meaningfully in the first quarter of 2026, exceeding levels seen in any quarter of 2025."

¹ $2.6 million of synergies on an annualized basis. Please reference slide 4 of Star's Q1 earnings call presentation.

Rick Coleman, COO of Star, added, "Residential and commercial construction markets remained soft in the first quarter causing our Building Solutions division to perform below internal expectations, primarily due to delays in several pending contract awards and severe winter weather in both of our key geographies. However, underlying demand remains intact, as evidenced by recently secured new business, including the $4.2 million multifamily housing project in New Hampshire for our KBS business we announced on April 30, 2026. In contrast, our Energy Services division delivered a strong quarter, continuing to gain share across core markets, with particularly strong performance in mining and geothermal end markets."

Mr. Eberwein concluded, "We remain focused on disciplined execution, rigorous cost management, and prudent capital allocation, including the active evaluation of M&A opportunities across all three of our operating divisions, as we continue to advance our strategic priorities. We believe we are well positioned to navigate near-term market volatility while driving increased profitability and long-term shareholder value."

* 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.

Adjusted net income or loss per diluted share should not be considered in isolation or as substitutes for net income or loss and net income or loss per share and other income or cash flow statement data prepared in accordance with generally accepted accounting principles or as measures of the Company's profitability or liquidity. Further, adjusted net income or loss and adjusted net income or loss per diluted share as presented above may not be comparable with similarly titled measures reported by other companies.
