Filing Explained

The filing adds two holder-relevant mechanics: 15,833 Q2 repurchased shares and a 4.99% ownership ceiling requiring board approval for additional shares.

Form 8-K reports specified material events; this August 14 filing furnishes Star Equity Holdings’ results for the quarter ended June 30, 2026 and an earnings presentation under Item 2.02. The exhibits are furnished rather than filed under Section 18.

The company reports that it repurchased $0.2 million of common stock, representing 15,833 shares, during the quarter. The repurchases are completed transactions; the $1.6 million remaining under the $3 million program is authorization capacity, not a committed additional purchase.

The company also states that its rights agreement and charter amendment limit beneficial ownership of common stock to 4.99%. A holder above that level, or already above it and seeking to buy more, requires the board’s prior written approval.

Key Terms

6 terms

Adjusted EBITDA financial

"Adjusted EBITDA (non-GAAP measure)* increased to $2.2 million versus adjusted EBITDA of $1.3 million"

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

net operating losses financial

"Our $215 million U.S. NOL position as of December 31, 2025 represents a meaningful tax asset"

Net operating losses are the amount by which a company’s allowable tax deductions exceed its taxable income in a given year, creating a tax loss that can be carried forward or backward to reduce taxes in other years. For investors this matters because NOLs can lower future tax payments and boost cash flow—think of them as unused tax credits a business can apply later to improve profitability and valuation or make the company more attractive in a sale or investment.

book-to-bill ratio financial

"Building Solutions quarter-end backlog was $10.6 million... and the trailing 12-month book-to-bill ratio was 0.77"

The book-to-bill ratio compares the value of new orders a company receives to the value of products it ships out or bills for over a certain period. If the ratio is above 1, it means the company is getting more orders than it is completing, which can indicate growth. If it's below 1, it suggests demand is slowing down.

rights agreement regulatory

"the Company has a rights agreement and charter amendment in place that limit beneficial ownership"

A rights agreement is a contract that grants existing shareholders special rights—commonly the option to buy additional shares at a set price or to trigger protections if a takeover is attempted. Think of it like a neighborhood watch rule that lets current homeowners buy extra lots or lock the gate when an outsider tries to take over the block; it matters to investors because it can dilute or protect share value and influence takeover outcomes.

stockholder rights plan regulatory

"the impact of our stockholder rights plan, or “poison pill,” on stockholder decision making"

A stockholder rights plan is a strategy used by a company to protect itself from unwanted takeovers by making it more difficult or expensive for an outside party to acquire a large ownership stake without approval. It often involves granting existing shareholders special rights that activate if someone attempts to buy a significant portion of the company, helping to safeguard the company's interests and giving investors confidence that decisions are made with stability in mind.

pro forma adjusted net income financial

"Pro forma adjusted net income per diluted share was $1.46 in the second quarter of 2025"

Star Equity Holdings Reports 2026 Second Quarter Results

Realized merger synergies of $3.0 million on annualized basis

OLD GREENWICH, CT - August 14, 2026 - Star Equity Holdings, Inc. (Nasdaq: STRR and STRRP) ("Star" or the "Company"), a diversified holding company, announced today financial results for the second quarter ended June 30, 2026.

2026 Second Quarter Summary

•Revenue of $54.9 million increased 54.6% from the second quarter of 2025.

•Gross profit of $22.8 million increased 22.3% from the second quarter of 2025.

•Net loss attributable to common shareholders was $2.5 million, or $0.66 per diluted share, compared to net loss attributable to common shareholders of $0.7 million, or $0.23 per diluted share, for the second quarter of 2025. Adjusted net loss per diluted share (non-GAAP measure)* was $0.15 compared to adjusted net income per diluted share of $0.20 in the second quarter of 2025. Pro forma adjusted net income per diluted share was $1.46 in the second quarter of 2025.

•Adjusted EBITDA (non-GAAP measure)* increased to $2.2 million versus adjusted EBITDA of $1.3 million in the second quarter of 2025; pro forma adjusted EBITDA was $8.5 million in the second quarter of 2025, including a $5.5 million realized gain in the Investments division.

•Total cash including restricted cash was $8.9 million at June 30, 2026.

Jeff Eberwein, CEO of Star, noted, "In the second quarter, Business Services delivered modest revenue growth, with gross profit down slightly year-over-year, while Energy Services posted strong year-over-year gains in revenue, gross profit, and adjusted EBITDA, reflecting activity increases and new client wins in the geothermal and mining industries. Building Solutions remained below our expectations due to market softness and contract timing including revenue from one large project largely constructed in Q2 that will now be recognized mainly in Q3. While residential and commercial construction markets remained challenging in the second quarter, we have gained traction in the areas of workforce, affordable, and assisted living/senior housing. We continued to add attractive work to the backlog, including the previously announced $4.2 million multifamily project in New Hampshire to serve the senior community."

Jake Zabkowicz, Global CEO of Hudson Talent Solutions ("HTS"), added, “HTS's revenues were up modestly year-over-year, despite continued macroeconomic uncertainty and sustained pressure in the professional talent market. We have maintained a strong focus on innovation and operational efficiency, including the expanded deployment of agentic AI and automation tools to enhance recruiter productivity, improve candidate matching, and deliver greater value to clients. These initiatives helped limit the year-over-year gross profit decline to 4% despite a mixed regional backdrop, with growth in the Americas offsetting softer conditions in Asia Pacific and EMEA. We believe our deep client relationships and continued focus on technology‑enabled delivery positions Hudson Talent Solutions to capitalize on improving market conditions over time.”

Mr. Eberwein concluded, "We remain focused on disciplined execution, rigorous cost management, and returns‑driven capital allocation, including the active evaluation of M&A opportunities across all three operating divisions. Our $215 million U.S. NOL position as of December 31, 2025 represents a meaningful tax asset that we expect to enhance after‑tax returns on future growth initiatives and strategic transactions. With the realization of synergies from the Star merger completed in August 2025, a strengthening Energy Services platform, and a resilient Business Services franchise, we believe we are well positioned to navigate near‑term market volatility, improve profitability, and create long‑term value for our stockholders.”

* 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.
