NOTE 1 –BASIS OF PRESENTATION

These interim unaudited condensed consolidated financial statements have been prepared in accordance with United States of America (“U.S.”) generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”) for interim financial reporting and should be read in conjunction with the consolidated financial statements and related notes of Star Equity Holdings, Inc. ("Star" or the “Company”, formerly known as Hudson Global, Inc. ("Hudson")) and Star Operating Companies, Inc. (formerly known as Star Equity Holdings, Inc.) filed in their respective Annual Reports on Form 10-K for the year ended December 31, 2024.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of operating revenues and expenses. These estimates are based on management’s knowledge and judgments. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows at the dates and for the periods presented have been included. The results of operations for interim periods are not necessarily indicative of the results of operations for the full year. The condensed consolidated financial statements include the accounts of the Company and all of its wholly owned subsidiaries. Intra-entity balances and transactions between and among the Company and its subsidiaries have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current year presentation with no material impact on the condensed consolidated financial statements. For more information, see Note 2 to the Condensed Consolidated Financial Statements.

ADOPTION OF ACCOUNTING POLICES PURSUANT TO MERGER

The accounting policies of SOC have been conformed to those of the Company where necessary. No significant differences in accounting policies were identified. As a result of the acquisition, the Company adopted the following accounting policies that were not previously applicable to its operations:

Fair Value of Financial Instruments

The authoritative guidance for fair value measurements defines fair value for accounting purposes, establishes a framework for measuring fair value, and provides disclosure requirements regarding fair value measurements. The guidance defines fair value as an exit price, which is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date. The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level of pricing observability. Financial instruments primarily consist of cash equivalents, equity securities, accounts receivable, other current assets, restricted cash, and accounts payable. The carrying amount of short-term and long-term debt and notes payable approximates fair value because of the relative short maturity of these instruments and interest rates we could currently obtain.

The Company occasionally enters into derivative financial instruments to manage certain market risks. These derivative instruments are not designated as hedging instruments and accordingly, are recorded at fair value in the Condensed Consolidated Balance Sheets with changes in fair value recognized in cost of revenues in the Condensed Consolidated Statements of Operations.

Equity Securities

Securities consist of investments in equity securities that are publicly traded. These equity securities are measured at fair value on a trade date basis and changes in fair value are recognized in net income in other income (expense). Investments that are strategic in nature, with the intent to hold the investment over a several year period, are classified as long-term investments.

Long-Term Investments

As a part of the sale of Digirad Health, Star Operating Companies received common equity in Insignia TTG Parent LLC (“Catalyst Parent”), the parent entity of Catalyst formerly known as TTG Imaging Solutions, LLC. In accounting for this investment, we have elected the measurement alternative under ASC 321 “Accounting for Investments in Equity Securities”. The measurement alternative election allows for equity securities that do not have readily determinable fair values to be recorded at cost, with adjustments for impairment and certain observable price changes reflected in earnings. Such securities are adjusted to fair value when an observable price change occurs or impairment is identified. Each reporting period, we perform a qualitative and quantitative assessment considering impairment indicators to evaluate whether the investment is impaired. Impairment indicators include, but are not limited to, significant deterioration in earnings performance, significant adverse changes in the regulatory or economic environment and working capital deficiencies. If an investment is determined to be impaired, we include an impairment loss as a component of other income (expense) equal to the difference between the fair value of the investment and its carrying amount. During the period ended September 30, 2025 we recognizedno impairment loss on this investment.

Index

On August 9, 2024, SOC completed an investment in Enservco Corporation (“Enservco”) (“Investment in Enservco”), which consisted of Enservco Common Stock, Enservco Preferred Stock, and certain other options reflected in the Share Exchange Agreement, and the Enservco Note Receivable (See Note 18, Supplementary Balance Sheet Information). The Investment in Enservco is required to be accounted for using the equity method of accounting under ASC 323, “Equity Method Investments and Joint Ventures”, as we are deemed to have significant influence over Enservco based upon GAAP rules. Pursuant to the guidance in ASC 323, we elected the fair value option pursuant to ASC 825-10-15, wherein the financial instrument is initially measured at estimated fair value as of the transaction issue date and then subsequently remeasured at estimated fair value as of each reporting period balance sheet date, with changes in the estimated fair value recognized as other income (expense) in the statement of operations. Enservco Common Stock is publicly traded, and the fair value is determined based on Enservco’s common stock close price as of the reporting date. The fair value of the Enservco Preferred Stock was based on the consideration of a number of objective and subjective factors, including third-party valuations and a company-specific economic outlook. To determine the fair value of the call option, the Company used the Black-Scholes option pricing model. The fair value of the Enservco Note was determined using a discounted cash flow model. Fair value assumptions are further described in Note 12, Fair Value Measurements. The Enservco Note was determined to be uncollectible as of December 31, 2024 and the value was reduced to $0. As described further in Note 18, Supplementary Balance Sheet Information, the value of the Enservco Note was fully collateralized and SOC called the collateral once it was determined that the note was in default.

Inventory

Inventories are valued using first-in, first-out, or the weighted-average inventory method; stated at the lower of cost or net realizable value. Finished goods and work-in-process inventory values include the cost of raw materials, labor, and manufacturing overhead. Inventory, when written down to net realizable value, establishes a new cost basis and its value is not subsequently increased based upon changes in underlying facts and circumstances. We also make adjustments to reduce the carrying amount of inventories for estimated excess or obsolete inventories. Factors influencing these adjustments include inventory on-hand compared with historical and estimated future sales and usage for new and existing products and assumptions about the likelihood of obsolescence.

Debt Issuance Costs

We incur debt issuance costs in connection with debt financings. Debt issuance costs for line of credit are presented in other assets and are amortized over the term of the revolving debt agreements using the straight-line method. Debt issuance costs for term debt are netted against the debt and are amortized over the term of the loan using the effective interest method. Amortization of debt issuance costs are included in interest expense. As of September 30, 2025 we haveno unamortized debt issuance costs.

Shipping and Handling Fees and Costs

We record all shipping and handling costs billed to customers as revenue earned for the goods provided. Shipping and handling costs related to continuing operations are included in cost of revenues and totaled $164 for the period ended September 30, 2025.

Warranties

Within our Building Solutions division, KBS provides a limited assurance warranty on its residential homes that covers substantial defects in materials or workmanship for a period of 12 months after delivery to the owner. EBGL provides a limited warranty on the sale of its wood foundation products that covers leaks resulting from defects in workmanship for a period of 25 years. TT provides a limited warranty on glulam products for a period of 50 years. Estimated warranty costs are accrued in the period that the related revenue is recognized. See Note 18, Supplementary Balance Sheet Information, for further information.

Advertising and Marketing Costs

Advertising and marketing costs are expensed as incurred. Total advertising and marketing costs for the three and nine months ended September 30, 2025 were $913 and $2,814, respectively

NOTE 3 –ACCOUNTING PRONOUNCEMENTS

Recent Accounting Standards Not Yet Adopted

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): "Improvements to Income Tax Disclosures", which modifies FASB Accounting Standards Codification 740 to enhance the transparency and decision usefulness of income tax disclosures. ASU No. 2023-09 is effective on a prospective basis for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of this new guidance and expects to adopt it in the annual report for the fiscal year ending December 31, 2025.

In November 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” This update requires public entities to disclose additional information about specific expense categories in the notes to the financial statements on both an interim and annual basis. Subsequently, in January 2025, the FASB issued ASU 2025-01, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. The new guidance is effective for the Company for fiscal years beginning after December 15, 2026, and for interim periods within annual reporting periods beginning after December 15, 2027. It may be applied on a retrospective or prospective basis, with early adoption permitted. The Company is currently evaluating the update to determine the impact on the Company’s disclosures.

In July 2025, the FASB issued Accounting Standards Update 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The ASU provides a practical expedient for estimating expected credit losses on current accounts receivable and contract assets arising from revenue transactions under ASC 606. Under the expedient, entities may assume that conditions existing as of the balance-sheet date will remain unchanged over the remaining life of those assets, thereby simplifying the estimation process for short-term receivables. The amendments are effective for fiscal years beginning after December 15, 2025, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU 2025-06, "Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software", ASU 2025-06 updates the accounting for internal-use software by removing the previous “project stage” model and requiring capitalization only when management authorizes and commits to funding a project that is probable of completion. The ASU also adds guidance on assessing development uncertainty, incorporates website development into Subtopic 350-40, and aligns presentation and disclosure requirements with ASC 360. The amendments are effective for annual periods beginning after December 15, 2027, and interim periods within those years, with early adoption permitted. Entities may apply the standard prospectively, modified-prospectively, or retrospectively. The Company is currently evaluating the impact of this guidance and does not expect the adoption to have a material effect on its consolidated financial statements.

Adoption of New Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The amendments in this ASU improve segment reporting requirements, primarily through enhanced disclosures on significant segment expenses. Other disclosures that the ASU requires public entities to provide include the title and position of the Chief Operating Decision Maker (“CODM”) and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. A public entity should apply the amendments in this ASU retrospectively to all prior periods presented in the financial statements. The Company adopted this ASU for the year ended December 31, 2024, and has disclosed significant expenses reviewed by the CODM for each reportable segment, with no additional significant expenses identified beyond those presented. See Note 17, “Segment and Geographic Data” to the Condensed Consolidated Financial Statements.

NOTE 4 –REVENUE RECOGNITION

Building Solutions Revenue Recognition. Within the Building Solutions division, we service residential and commercial construction projects by manufacturing modular housing units and other products, supplying general contractors with building materials and providing glue-laminated timber products (“glulam”) to distributors and end users. KBS manufactures modular buildings for both single-family residential homes and larger, commercial building projects. EdgeBuilder manufactures structural wall panels, permanent wood foundation systems, and other engineered wood products, and Glenbrook is a retail supplier of lumber and other building supplies. Retail sales at Glenbrook are recognized at the point of sale. TT manufactures glulam for various end markets and applications, including agriculture, industrial, infrastructure, and building construction (commercial and residential). For bill and hold sales, we determine when the customer obtains control of the product on a case-by-case basis to determine the amount of revenue to recognize each period. Revenue is generally recognized at point in time upon delivery of product or over time by measuring progress towards completion. There are no contracts as of September 30, 2025 that are subject to over time recognition.

Business Services Revenue Recognition. We account for a contract when both parties to the contract have approved the contract, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. Revenues are recognized over time or as services are delivered to customers, using an input or output method, as the control of the promised services is transferred to the client in an amount that reflects the consideration we expect to be entitled to in exchange for those services. The majority of our contracts are short-term in nature as they include termination clauses that allow either party to cancel within a short termination period, without cause. Revenue includes billable travel and other reimbursable costs and is reported net of sales or use taxes collected from clients and remitted to taxing authorities.

We generally determine standalone selling prices based on the prices included in our client contracts, using expected cost plus profit, or other observable prices. The price as specified in our client contracts is generally considered the standalone selling price as it is an observable input that depicts the price as if sold to a similar client in similar circumstances. Certain client contracts have variable consideration, including usage-based fees that increase the transaction price and volume rebates or other similar items that generally reduce the transaction price. We estimate variable consideration using the expected value method based on the terms of the client contract and historical evidence. These amounts may be constrained and are only included in revenue to the extent we do not expect a significant reversal when the uncertainty associated with the variable consideration is resolved. Other than bonuses to be paid to contractors, on behalf of our clients, our estimated amounts of variable consideration subject to constraints are not material, and we do not believe that there will be significant changes to our estimates. Certain contract employees are entitled to performance bonuses at the sole discretion of the client and are constrained until approved. $0.1 million and $1.1 million in bonuses were approved and paid to our contract employees in the three and nine months ended September 30, 2025, respectively. No bonuses were approved and paid to our contract employees on behalf of our clients for the three and nine months ended September 30, 2024.

We record accounts receivable when our right to consideration becomes unconditional. Contract assets primarily relate to our rights to consideration for services provided that such rights to consideration are conditional on satisfaction of future performance obligations. A contract liability for deferred revenue is recorded when consideration is received, or is unconditionally due, from a client prior to transferring control of services to the client under the terms of a contract. Deferred revenue balances typically result from advance payments received from clients prior to transferring control of services. Other than deferred revenue, we do not have any material contract assets or liabilities as of and for the nine months ended September 30, 2025 and 2024.

Payment terms vary by client and the services being provided to the client. We consider payment terms that exceed one year to be extended payment terms. Substantially all of the Company’s contracts include payment terms of 90 days or less, and we do not extend payment terms beyond one year.

We primarily record revenue on a gross basis in the Condensed Consolidated Statements of Operations and Comprehensive Income based upon the following key factors:

•We maintain the direct contractual relationship with the client and are responsible for fulfilling the service promised to the client.

• 12 -

Index

•We maintain control over our contractors while the services to the client are being performed, including our contractors’ billing rates, and are ultimately responsible for paying them.

RPO. We provide complete recruitment outsourcing, project-based outsourcing, and recruitment consulting services for clients’ permanent staff hires. We recognize revenue for our RPO over time in an amount that reflects the consideration we expect to be entitled to and have an enforceable right to payment in exchange for our services. The client simultaneously receives and consumes the benefits of the services as they are provided. The transaction prices contain both fixed fees and variable consideration. Variable consideration is constrained by candidates accepting offers of permanent employment. We recognize revenue on fixed fees as the performance obligations are satisfied and variable fees as the constraint is lifted. We do not incur incremental costs to obtain our RPO contracts. The costs to fulfill these contracts are expensed as incurred.

We recognize permanent placement revenue when employment candidates accept offers of permanent employment. We have a substantial history of estimating the financial impact of permanent placement candidates who do not remain with our clients through a guarantee period. Fees to clients are generally calculated as a percentage of the new employee’s annual compensation. No fees for permanent placement services are charged to employment candidates.

Contracting. We provide clients with a range of outsourced professional contract staffing services and managed service provider services, sometimes offered on a standalone basis and sometimes offered as part of a blended total talent solution. We recognize revenue for our contracting services over time as services are performed in an amount that reflects the consideration we expect to be entitled to and have an enforceable right to payment in exchange for our services, which is generally calculated as hours worked multiplied by the agreed-upon hourly bill rate. The client simultaneously receives and consumes the benefits of the services as they are provided. We do not incur incremental costs to obtain our contracts for outsourced professional contract staffing services and managed service provider services. The costs incurred to fulfill these contracts are expensed as incurred.

Unsatisfied performance obligations. As a practical expedient, we do not disclose the value of unsatisfied performance obligations for (i) contracts with an expected original duration of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

Energy Services Revenue Recognition. ADT is principally engaged in the business of renting drilling tools. We also sell new drilling tools, drilling parts, supplies, and used rental tools. In addition, ADT offers repair services to support its customers. Tools purchased for sale are recorded as inventory. Tools intended for rental are recorded as part of fixed assets. Equipment rental revenue is recognized on a straight-line basis over the length of the rental contract. New tools, parts, and supplies sales are recognized as revenue upon transfer of control, which generally occurs when products are picked up by or delivered to the customer. Repair services revenues are recognized in the period the services are provided. Upon the sale of other rental tools from fixed assets, we recognize a gain or loss on the sale in other income / expense, net.

ADT’s equipment rental agreements generally contain provisions whereby should the rented tools or components provided to a customer be deemed to be irretrievably lost during drilling operations, commonly referred to as “lost-in-hole,” the Company has the right to receive reimbursement for such losses. Amounts billed to customers are at an agreed upon price relative to the specific piece of equipment, the revenue of which is recognized at the time the loss of the equipment is confirmed. The gross profit recognized from lost-in-hold transactions is normally calculated as the difference between the amounts billed to the customer and the net book value of the lost equipment. This gross profit is presented as a separate line item in the statement of cash flows under operating activities, and the cash received in connection with these activities is presented as an offset to cash purchases of property and equipment in the investing section of the statement of cash flows, to the extent it does not exceed the cash used for the purchases of the replacement equipment. Revenue recognized for the period ended September 30, 2025, totaled $147. No significant lost-in-hole reimbursements were outstanding or contingent as of the end of the third quarter.

Billings in excess of costs and estimated profit. We recognize billings in excess of costs and estimated profit on uncompleted contracts within current liabilities. Such amounts relate to fixed-price contracts recognized over time, and represents payments in advance of performing the related contract work. Billings in excess of costs and estimated profit on uncompleted contracts are not considered to be a significant financing component because they are generally used to meet working capital demands that can be higher in the early stages of a contract. Contract liabilities are reduced when the associated revenue from the contract is recognized, which is generally within one year. There areno liabilities associated with billings in excess of costs at September 30, 2025.

• 13 -

Index

Contract Costs. We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. The Company applies a practical expedient to expense costs as incurred for these costs when the amortization period is one year or less. These costs primarily consist of internal sales commissions; under the terms of these programs these are generally earned and the costs are recognized at the time the associated revenue is recognized. As of September 30, 2025, there were no contract costs recognized.

Deferred Revenue. Deferred revenue represents customer deposits and advanced payments for contracts that are subject to point-in-time recognition, or payments received prior to transferring control of services to customers. We have determined our contracts do not include a significant financing component.

Changes in deferred revenue for the nine months ended September 30, 2025 are as follows:

NOTE 5 –ACQUISITIONS

Star Operating Companies

On August 22, 2025, the Company completed its previously announced acquisition of SOC pursuant to the Agreement and Plan of Merger, dated as of May 21, 2025 (the “Merger Agreement”). This resulted in a business combination pursuant to ASC 805, Business Combinations.

The terms of the Merger Agreement determined consideration for the purchase as follows: at the Effective Time, (i) each share of common stock of SOC issued and outstanding immediately prior to the Effective Time (other than certain shares as set forth in the Merger Agreement) were automatically converted into the right to receive 0.23 shares of Company common stock and (ii) each share of preferred stock of SOC issued and outstanding immediately prior to the Effective Time (other than certain shares set forth in the Merger Agreement) were automatically converted into the right to receive one (1) share of Star 10% Series A Cumulative Perpetual preferred stock (“Preferred Stock”). As a result of the Merger, former SOC common stockholders received approximately 744,291 shares of Star common stock for their SOC common shares and former SOC stockholders received approximately 2,690,637 shares of Preferred Stock. No fractional shares of Star common stock were issued in the Merger, and SOC stockholders became entitled to receive cash in lieu of fractional shares in accordance with the Merger Agreement. The total consideration paid for SOC, which represents the fair value of the common and preferred stock, totaled approximately $32,174. Prior to the completion of the Merger Agreement, the Company determined that the Merger Agreement was in the best interests of the Company and for each of the Star and the SOC stockholders.

In accordance with ASC 805, Business Combinations, we accounted for this transaction as a business combination and recorded the acquired assets of SOC at their estimated fair value. The valuation of assets acquired and liabilities assumed has not yet been finalized as of September 30, 2025. The purchase price allocation is preliminary and subject to change, including the valuation of property and equipment, intangible assets, inventory, income taxes, and goodwill, among other items. The amounts recognized will be finalized as the information necessary to complete the analysis is obtained, but no later than one year after the acquisition date. Finalization of the valuation during the measurement period could result in a change in the amounts recorded for the acquisition date fair value. The fair values of assets acquired and liabilities assumed were determined using valuation techniques consistent with ASC 820, Fair Value Measurement. These fair value measurements are considered nonrecurring and were determined as of the acquisition date. As noted in Note 2, Description of Business, SOC is reported as part of our Building Solutions, Energy Services, and Investments segments. The Company incurred transaction costs related to the SOC Acquisition of $1,600 that were expensed as part of “Office and general”.

The following represents certain information from the unaudited pro forma condensed Consolidated Statement of Operations as if SOC had been included in the consolidated results of the Company for the three and nine months ending September 30, 2025 and 2024:

Alpha Consulting Group Acquisition

On July 23, 2025, the Company announced that it had acquired Alpha Consulting Group (“ACG”) (“Seller”), a Japan-based provider of recruitment services. The acquisition of ACG represents the Company’s entry into the Japanese market as part of its localization strategy for its Business Services segment. In connection with the ACG acquisition, the Seller received total $146 in cash, subject to certain adjustments, at closing. There were no earn-out payment arrangements associated with the transaction. The ACG acquisition was accounted for as a business combination under the acquisition method of accounting.

NOTE 6 –STOCK-BASED COMPENSATION

Incentive Compensation Plan

The Company maintains the Hudson Global, Inc. 2009 Incentive Stock and Awards Plan, as amended and restated on May 24, 2016 and further amended on September 14, 2020, May 17, 2022, and August 22, 2025 (the “ISAP”), pursuant to

which it can issue equity-based compensation incentives to eligible participants. The ISAP permits the granting of stock options, restricted stock, restricted stock units, and other types of equity-based awards. The Compensation Committee (the “Compensation Committee”) of the Board of Directors (the “Board”) will establish such conditions as it deems appropriate for the granting or vesting of stock options, restricted stock, restricted stock units and other types of equity-based awards. As determined by the Compensation Committee, equity awards may also be subject to immediate vesting upon the occurrence of certain events including death, disability, retirement or a change in control of the Company. When we make grants of restricted stock or restricted stock units to our executive officers, including the named executive officers, we enter into Restricted Stock Agreements and Restricted Stock Unit Agreements with such executive officers that contain provisions that are triggered upon a termination of an executive officer or a change in control of our Company. For awards of restricted stock granted beginning on November 6, 2015, effective upon a change in control of our Company, if the executive is employed by us or an affiliate of ours immediately prior to the date of such change in control and is subsequently terminated within 12 months following the date of such change in control, the shares of restricted stock will fully vest and the restrictions imposed upon the restricted stock will be immediately deemed to have lapsed. For awards of restricted stock units granted beginning on March 10, 2016, effective upon a change in control of our Company, if the executive is employed by us or an affiliate of ours immediately prior to the date of such change in control and is subsequently terminated within 12 months following the date of such change in control, the restricted stock units will fully vest and the restrictions imposed upon the restricted stock units will be immediately deemed to have lapsed. The Company primarily grants restricted stock and restricted stock units to its employees. A restricted stock unit is equivalent toone share of the Company’s common stock and is payable only in common stock of the Company issued under the ISAP.

The Compensation Committee administers the ISAP and may designate any of the following as a participant under the ISAP: any officer or other employee of the Company or its affiliates or individuals engaged to become an officer or employee, consultants or other independent contractors who provide services to the Company or its affiliates, and non-employee directors of the Company. On August 21, 2025, the Company’s stockholders at the 2025 Annual Meeting of Stockholders approved amendments to the ISAP to, among other things, increase the number of shares of the Company’s common stock that are reserved for issuance by 400,000 shares and to permit the issuance of 175,000 shares of the Company’s preferred stock. As of September 30, 2025, there were 388,722 shares of the Company’s common stock available for future issuance under the ISAP.

All share issuances related to stock compensation plans are issued from the aforementioned stock available for future issuance under stockholder approved compensation plan.

For the nine months ended September 30, 2025, the Company granted 48,688 restricted stock units subject to performance vesting conditions for the year ended December 31, 2025. In addition, the Company granted 8,918 time-vested restricted stock units to a certain employee that were not subject to performance conditions. For the nine months ended September 30, 2024, the Company granted 47,647 restricted stock units subject to performance vesting conditions for the year ended December 31, 2024, and granted 12,540 of discretionary time-vested restricted stock units to certain employees that were not subject to performance conditions. In connection with the merger on August 22, 2025, the Company converted the unvested restricted stock unit awards previously granted under SOC’s equity incentive plans at the exchange ratio of 0.23 shares to 1. As of the merger date, these assumed awards consisted of 22,717 performance-based restricted stock units and 6,046 time-based restricted stock units. The assumed awards continue to be subject to their original vesting terms and conditions, and are recognized as part of the Company’s ongoing stock-based compensation expense.

A summary of the quantity and vesting conditions for stock-based units granted to the Company’s employees for the nine months ended September 30, 2025 was as follows:

(1)The performance conditions with respect to restricted stock units may be satisfied as follows:

(a)For grants to Corporate office employees subject to 2025 performance conditions,100% of the restricted stock units may be earned on the basis of performance as measured by a “group adjusted EBITDA”.

Index

(2)To the extent restricted stock units are earned, such restricted stock units will vest on the basis of service as follows:

(a)33% and 66.6% for Type 1 and Type 2, respectively, of the restricted stock units will vest on the first anniversary of the grant date;

(b)33% and 16.7% for Type 1 and Type 2, respectively, of the restricted stock units will vest on the second anniversary of the grant date; and

(c)34% and 16.7% for Type 1 and Type 2, respectively, of the restricted stock units will vest on the third anniversary of the grant date; provided that, in each case, the employee remains employed by the Company from the grant date through the applicable service vesting date.

The Company also maintains the Director Deferred Share Plan (the “Director Plan”) as part of the ISAP pursuant to which it can issue restricted stock units to its non-employee directors. A restricted stock unit is equivalent toone share of the Company’s common stock, and prior to the acquisition of SOC were payable in common stock issued under the ISAP upon a director ceasing service as a member of the Company’s Board. Restricted stock units granted to directors vest over one year. Restricted stock units issued under the Director Plan contain the right to a dividend equivalent award in the form of additional restricted stock units. The dividend equivalent award is calculated using the same rate as the cash dividend paid on a share of the Company’s common stock, and then divided by the closing price of the Company’s common stock on the date the dividend is paid to determine the number of additional restricted stock units to grant. Dividend equivalent awards have the same vesting terms as the underlying awards. During the nine months ended September 30, 2025, the Company granted a total of 54,241 RSUs to its non-employee directors.

As of September 30, 2025,14,913 restricted stock units are deferred under the Company’s ISAP.

For the three and nine months ended September 30, 2025 and 2024, the Company’s stock-based compensation expense related to restricted stock units and restricted shares of common stock were as follows:

Restricted Stock Units

As of September 30, 2025, the Company had $751 of unrecognized stock-based compensation expense related to outstanding unvested restricted stock units. The Company expects to recognize that cost over a weighted average service period of 0.8 years. Restricted stock units have no voting or dividend rights until the awards are vested.

NOTE 7 –INCOME TAXES

Income Tax Provision

Under ASC 270, “Interim Reporting”, and ASC 740-270, “Income Taxes – Interim Reporting”, the Company is required to adjust its effective tax rate for each quarter to be consistent with the estimated annual effective tax rate. Jurisdictions with a projected loss for the full year where no tax benefit can be recognized are excluded from the calculation of the estimated annual effective tax rate. Applying the provisions of ASC 270 and ASC 740-270 could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections.

Effective Tax Rate

The provision for income taxes for the nine months ended September 30, 2025 was $626 on a pre-tax loss of $3,582, compared to a provision for income taxes of $463 on pre-tax loss of $3,722 for the same period in 2024. The Company’s effective income tax rate ("ETR") was negative 17% and negative 12% for the nine months ended September 30, 2025 and 2024, respectively. For the nine months ended September 30, 2025, the effective tax rates differed from the U.S. Federal statutory rate of 21% primarily due to pretax losses for which no tax benefit can be recognized, foreign tax rate differences, and non-deductible expenses. For the nine months ended September 30, 2024, the effective tax rates differed from the U.S. Federal statutory rate of 21% primarily due to changes in valuation allowances in the U.S. and certain foreign jurisdictions, which reduces or eliminates the effective tax rate on current year profits or losses, foreign tax rate differences, and non-deductible expenses. The current year-to-date effective tax rate differs significantly from the prior period effective tax rate primarily due to the interaction of rate reconciliation items, including changes in valuation allowance.

Uncertain Tax Positions

As of both September 30, 2025 and December 31, 2024, the Company had $60, respectively, of unrecognized tax benefits, excluding interest and penalties, which, if recognized in the future, would lower the Company’s effective income tax rate.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits as part of the provision for income taxes. As of September 30, 2025 and December 31, 2024, the Company had $37 and $33, respectively, of accrued interest and penalties associated with unrecognized tax benefits.

Based on information available as of September 30, 2025, it is reasonably possible that the total amount of unrecognized tax benefits could decrease by $0 over the next 12 months as a result of projected resolutions of global tax examinations and controversies and potential expirations of the applicable statutes of limitations.

In many cases, the Company’s unrecognized tax benefits are related to tax years that remain subject to examination by the relevant tax authorities. Tax years with net operating losses (“NOLs”) remain open until such losses expire or until the statutes of limitations for those years when the NOLs are used expire. As of September 30, 2025, the Company’s open tax years, which remain subject to examination by the relevant tax authorities, are between 2019 and 2025 depending on the jurisdiction.

The Company believes that its unrecognized tax benefits as of September 30, 2025 are appropriately reflected for all years subject to examination above.

Net Operating Losses (“NOLs”), Capital Losses, and Valuation Allowance

The Company recorded a valuation allowance against all of our consolidated US deferred tax assets for NOLs and Capital Losses as of September 30, 2025 and December 31, 2024. We intend to continue maintaining a full valuation allowance on our deferred tax assets for NOLs until there is sufficient evidence to support the reversal of all or some portion of these allowances in the future.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was signed into law. The OBBBA includes a broad range of tax reform provisions that may affect the Company’s financial results. The OBBBA has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company is currently evaluating the impact of these provisions which could affect the Company’s income tax expense and deferred tax assets; however, it is not expected to have a material impact to our Consolidated Financial Statements.

NOTE 8 –ACCOUNTS RECEIVABLE, NET

Within our Building Solutions and Energy Services segments, accounts receivable consist principally of trade receivables from customers. These are recorded at the invoiced amount and are generally unsecured and due within 30 days. Trade receivables do not bear interest. We use an expected loss methodology. This methodology includes information about past events, current economic conditions and reasonable and supportable forecasts that impact the collectibility of the reported amounts of the receivables over their lifetime. Within the Current Expected Credit Losses (“CECL”) guidelines, we utilize a “probability of default” methodology to determine expected credit losses under the CECL model. Account balances are charged off against the allowance when we believe it is probable the receivable will not be recovered. Our “probability of default” methodology principally entails evaluating the collectability of our trade receivables and providing reserves for doubtful accounts based on our historical experience rate, known collectability issues and disputes, and our bad debt write-off history. Within our Business Services segment, accounts receivable balances are composed of trade and unbilled receivables. Unbilled accounts receivable represent revenue recorded in advance of processing formal invoices pursuant to the completion of contract provisions and, generally, become billable at contractually specified dates.

Our estimates of collectability could be impacted by material amounts due to changed circumstances, such as a higher number of defaults or material adverse changes in a payor’s ability to meet its obligations. Expected credit losses related to trade accounts receivable are recorded as an allowance for doubtful accounts within accounts receivable, net in the

Consolidated Balance Sheets, and the related provision for doubtful accounts is charged to office and general expenses. We do not have any off-balance sheet credit exposure related to our customers.

Unbilled receivables of $9,380 and $5,925 as of September 30, 2025 and December 31, 2024, respectively, are expected to be invoiced and collected within one year. The Company records accounts receivable when its right to consideration becomes unconditional. Contract assets primarily relate to our rights to consideration for services provided that are conditioned on satisfaction of future performance obligations. Accounts receivable, net, are stated at the amount the Company expects to collect, which is net of estimated losses resulting from the inability of its customers to make required payments.

NOTE 12 –FAIR VALUE MEASUREMENTS

The Financial Accounting Standards Board’s authoritative guidance for fair value measurements establishes a three-level hierarchy based upon the inputs to the valuation model of an asset or liability. Assets and liabilities presented at fair value in our Consolidated Balance Sheets are generally categorized as follows:

Level 1: Quoted prices in active markets for identical assets or liabilities.

Level 2: Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Such assets and liabilities may have values determined using pricing models, discounted cash flow methodologies, or similar techniques, and include instruments for which the determination of fair value requires significant management judgment or estimation.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of assets and liabilities and their placement within the fair value hierarchy levels. The following table sets forth by level within the fair value hierarchy our assets and liabilities that were recorded at fair value as of September 30, 2025:

The Level 3 liabilities consist of an earnout liability associated with SOC's acquisition of Big Lake Lumber (“BLL”) in 2023. The change in the Level 3 liability during the period was primarily due to additional accruals recognized. These changes are included in "Purchases, issuances, and settlements (net)" in the Level 3 rollforward below.

Assets and Liabilities Measured at Fair Value on a Non-recurring Basis

Certain assets acquired and liabilities assumed in connection with the SOC acquisition were measured at fair value on a nonrecurring basis as of the acquisition date.

Additional information regarding the valuation methodologies and assumptions used in determining these fair values is included in Note 5 – Acquisitions, which presents the allocation of purchase consideration and related fair value measurements required under ASC 805, Business Combinations.

As of September 30, 2025, we had a net long (buying) position of 220,000 board feet under 8 lumber derivatives contracts with a November 30, 2025 expiration date.

Gains and losses from lumber derivative contracts are recorded in the cost of revenues in the Condensed Consolidated Statements of Operations and included the following for the period ended September 30, 2025:

NOTE 13 –LOSS PER SHARE

Basic loss per share is computed by dividing the Company’s net loss by the weighted average number of shares outstanding during the period. When the effects are not anti-dilutive, diluted loss per share is computed by dividing the Company’s net loss by the weighted average number of shares outstanding and the impact of all dilutive potential common shares, primarily stock options “in-the-money”, unvested restricted stock, and unvested restricted stock units. We have not allocated net income (loss) attributable to warrants because the holders of our warrants are not contractually obligated to share in our income (loss). The dilutive impact of stock options, unvested restricted stock, and unvested restricted stock units is determined by applying the “treasury stock” method. Performance-based restricted stock awards are included in the computation of diluted loss per share only to the extent that the underlying performance conditions: (i) are satisfied prior to the end of the reporting period; or (ii) would be satisfied if the end of the reporting period were the end of the related performance period and the result would be dilutive under the treasury stock method. Stock awards subject to vesting or exercisability based on the achievement of market conditions are included in the computation of diluted earnings per share only when the market conditions are met.

(a) The diluted weighted average number of shares of common stock outstanding did not differ from the basic weighted average number of shares of common stock outstanding because the effects of any potential common stock equivalents (see Note 6 to the Condensed Consolidated Financial Statements for further details on unvested restricted stock units) were anti-dilutive and therefore not included in the calculation of the denominator of dilutive earnings per share.

NOTE 14 –STOCKHOLDERS’ EQUITY

Common Stock

On August 8, 2023, the Company’s Board of Directors authorized a share repurchase program for up to $5,000 of the Company’s outstanding common stock. The Company continues to view share repurchases as an attractive use of capital and may repurchase shares from time to time, as market conditions warrant, through open market purchases, privately negotiated transactions, block trades, or other methods, in accordance with applicable federal securities laws, including Rule 10b-18 of the Securities Exchange Act of 1934 (the “Exchange Act”). This authorization does not expire.

During the nine months ended September 30, 2025, the Company completed its $5,000 share repurchase program authorized on August 8, 2023. On September 10, 2025, the Board of Directors authorized a new common stock repurchase program under which the Company may repurchase up to $3,000 of its outstanding common stock. During the nine months ended September 30, 2025, the Company repurchased a total of 274,922 shares of its common stock for an aggregate cost of $2.6 million under these authorizations. Of this total,261,052 shares were repurchased on September 25, 2025, in connection with a transaction with a certain shareholder totaling $2.44 million, and the remaining 13,870 shares were repurchased on the open market for a cost of $131. As of September 30, 2025, under the July 30, 2015, August 8, 2023 and September 10, 2025 authorizations combined, the Company had repurchased an aggregate of 942,418 shares for a total cost of $15,454, completing the August 8, 2023 authorization and leaving $2,547 available for purchase under the September 10, 2025 authorization. During the nine months ended September 30, 2024 the Company repurchased a total of 154,084 shares of its common stock for a cost of $2,495 under this authorization. Of these shares,44,250 shares were repurchased on January 29, 2024 in connection with a transaction with a certain shareholder totaling $655 that excludes tax withholdings. The Company also repurchased 69,567 shares during the second quarter in connection with transactions with certain shareholders totaling $1,181, as well as 40,267 shares of its common stock on the open market for a cost of $659.

The Company cannot predict when or if it will repurchase any shares of common stock as such stock repurchase program will depend on a number of factors, including constraints specified in any Rule 10b5-1 trading plans, price, general business and market conditions, and alternative investment opportunities. Information regarding share repurchases will be available in the Company’s periodic reports on Form 10-Q and 10-K filed with the Securities and Exchange Commission as required by the applicable rules of the Exchange Act.

NOTE 15 –PERPETUAL PREFERRED STOCK

Holders of shares of our Series A Preferred Stock are entitled to receive, when, as, and if, authorized by the Company’s board of directors (or a duly authorized committee of the Company’s board of directors) and declared by the Company out of funds legally available for the payment of dividends, preferential cumulative cash dividends at the rate of 10% per annum of the liquidation preference of $10 per share. Dividends are payable quarterly, in arrears, by the last calendar day of March, June, September and December to holders of record at the close of business on the first day of each payment month. The Series A Preferred Stock is not convertible and does not have any voting rights, except when dividends are in arrears for 6 or more consecutive quarters, then the holders of those shares together with holders of all other series of preferred stock equal in rank would be entitled to vote separately as a class for the election of 2 additional directors to board of directors, until all dividends accumulated on such shares of Series A Preferred Stock for the past dividend periods and the dividend for the current dividend period shall have been fully paid or declared and a sum sufficient for the payment thereof set apart for payment. The Series A Preferred Stock is not subject to redemption by the Company.

On August 22, 2025, we announced that our board of directors declared a cash dividend to holders of our Series A Preferred Stock of $0.025 per share for an aggregate amount of approximately $67. The record date for this dividend was September 1, 2025, and the payment date was September 10, 2025. As of September 30, 2025, we are current on our preferred dividend payments.

NOTE 16 –STOCKHOLDER RIGHTS PLAN

On October 15, 2018, the Company’s Board of Directors declared a dividend to the Company’s stockholders of record as of the close of business on October 25, 2018 (the “Record Date”), for each outstanding share of the Company’s common stock, ofone right (a “Right”) to purchase one one-hundredth of a share of a new series of participating preferred stock of the Company. The terms of the Rights are set forth in the Rights Agreement, dated as of October 15, 2018 (as amended, the “Rights Agreement”), by and between the Company and Computershare Trust Company, N.A., as rights agent (the “Rights Agent”). The Company’s stockholders approved the Rights Agreement at the Company’s 2019 Annual Meeting of Stockholders held on May 6, 2019. On September 28, 2021, the Company and the Rights Agent entered into a First Amendment to Rights Agreement (the “Amendment”) that amended the Rights Agreement to extend its term through October 15, 2024. The amendment was approved by the Board on September 28, 2021, subject to stockholder approval, and the Company’s stockholders approved the Amendment at the Company’s 2022 Annual Meeting of Stockholders held on May 17, 2022. The Board of Directors has taken further action to amend the Original Rights Agreement, as amended by the First Amendment, to extend the expiration of the Rights Agreement to October 15, 2027, as contemplated in the Second Amendment to Rights Agreement (the “Second Amendment”). The Second Amendment was approved by the Board on June 13, 2024, subject to stockholder approval, and the Company’s stockholders approved the Amendment at the Company’s 2024 Annual Meeting of Stockholders held on July 31, 2024.

The Company also has a provision in its Amended and Restated Certificate of Incorporation which generally prohibits transfers of its common stock that could result in an ownership change.

Each Right allows its holder to purchase from the Company one one-hundredth of a share of the Company’s Series B Junior Participating Preferred Stock (“Series B Preferred Stock”) for a purchase price of $3.50. Each fractional share of Series B Preferred Stock would give the stockholder approximately the same dividend, voting and liquidation rights as doesone share of common stock. Prior to exercise, however, a Right does not give its holder any dividend, voting or liquidation rights.

The Board entered into the Rights Agreement in an effort to preserve the value of the Company’s significant U.S. NOLs and other tax benefits. The Company’s ability to utilize its NOLs may be substantially limited if the Company experiences an “ownership change” within the meaning of Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”). In general, an “ownership change” would occur if the percentage of the Company’s ownership by one or more “5-percent shareholders” (as defined in the Code) increases by more than 50 percent over the lowest percentage owned by such stockholders at any time during the prior three years. The Rights Agreement is designed to preserve the Company’s tax benefits by deterring transfers of common stock that could result in an “ownership change” under Section 382 of the Code. In general terms, the Rights Agreement imposes a significant penalty upon any person or group that acquires beneficial ownership (as defined under the Rights Agreement) of 4.99% or more of the outstanding common stock without the prior approval of the Board (an “Acquiring Person”). Any Rights held by an Acquiring Person are void and may not be exercised.

• 34 -

The Company also has a provision in its Amended and Restated Certificate of Incorporation (the “Charter Provision”) which generally prohibits transfers of its common stock that could result in an ownership change.

The Rights will not be exercisable until the earlier of (i)10 days after a public announcement by the Company that a person or group has become an Acquiring Person; and (ii)10 business days (or a later date determined by the Board) after a person or group begins a tender or an exchange offer that, if completed, would result in that person or group becoming an Acquiring Person.

Until the date that the Rights become exercisable (the “Distribution Date”), common stock certificates will also evidence the Rights and will contain a notation to that effect. Any transfer of shares of common stock prior to the Distribution Date will constitute a transfer of the associated Rights. After the Distribution Date, the Rights will separate from the common stock and be evidenced by Right certificates, which the Company will mail to all holders of Rights that have not become void. After the Distribution Date, if a person or group already is or becomes an Acquiring Person, all holders of Rights, except the Acquiring Person, may exercise their Rights upon payment of the purchase price to purchase shares of common stock (or other securities or assets as determined by the Board) with a market value oftwo times the purchase price (a “Flip-in Event”). After the Distribution Date, if a Flip-in Event has already occurred and the Company is acquired in a merger or similar transaction, all holders of Rights, except the Acquiring Person, may exercise their Rights upon payment of the purchase price, to purchase shares of the acquiring or other appropriate entity with a market value oftwo times the purchase price of the Rights. Rights may be exercised to purchase Series B Preferred Stock only after the Distribution Date occurs and prior to the occurrence of a Flip-in Event as described above. A Distribution Date resulting from the commencement of a tender offer or an exchange offer as described in the second bullet point above could precede the occurrence of a Flip-in Event, in which case the Rights could be exercised to purchase Series B Preferred Stock. A Distribution Date resulting from any occurrence described in the first bullet point above would necessarily follow the occurrence of a Flip-in Event, in which case the Rights could be exercised to purchase shares of common stock (or other securities or assets) as described above.

The Rights will expire on the earliest of (i) the close of business on October 15, 2027, or such earlier date as of which the Board determines that this Agreement is no longer necessary for the preservation of Tax Benefits, (ii) the time at which the Rights are redeemed as provided in Section 23, (iii) the time at which all exercisable Rights are exchanged as provided in Section 24, (iv) the close of business on the effective date of the repeal of Section 382 of the Code or any successor or replacement provision if the Board determines that this Agreement is no longer necessary for the preservation of Tax Benefits, and (v) the Close of Business on the first day of a taxable year of the Company to which the Board determines that no Tax Benefits may be carried forward.

The Board may redeem all (but not less than all) of the Rights for a redemption price of $0.001 per Right at any time before the later of the Distribution Date and the date of the first public announcement or disclosure by the Company that a person or group has become an Acquiring Person. Once the Rights are redeemed, the right to exercise the Rights will terminate, and the only right of the holders of such Rights will be to receive the redemption price.

The Board may adjust the purchase price of the Series B Preferred Stock, the number of shares of Series B Preferred Stock issuable and the number of outstanding Rights to prevent dilution that may occur as a result of certain events, including, among others, a stock dividend, a stock split or a reclassification of the Series B Preferred Stock or common stock.

Before the time the Rights cease to be redeemable, the Board may amend or supplement the Rights Agreement without the consent of the holders of the Rights, except that no amendment may decrease the redemption price below $0.001 per Right.

NOTE 17 –SEGMENT AND GEOGRAPHIC DATA

Segment Reporting

Corporate expenses are reported separately for thefour reportable segments and pertain to certain functions, such as executive management, corporate governance, investor relations, legal, accounting, tax, and treasury. A portion of these expenses are attributed to the reportable segments for providing the above services to them, and have been allocated to the segments as management service expenses, and are included in the segments’ non-operating other income (expense). We have disclosed for each reportable segment the significant expense that is reviewed by CODM in the tables below with no additional significant expenses beyond those presented. Segment information is presented in accordance with ASC 280, “Segment Reporting.” This standard is based on a management approach that requires segmentation based upon the Company’s internal

• 35 - organization and disclosure of revenue and certain expenses based upon internal accounting methods. The Company’s financial reporting systems present various data for management to run the business, including internal profit and loss statements prepared on a basis not consistent with U.S. GAAP. Accounts receivable and long-lived assets are the only significant assets separated by segment for internal reporting purposes.

Our reportable segments are based upon our internal organizational structure, the manner in which our operations are managed, the criteria used by our Chief Executive Officer, who is our Chief Operating Decision Maker (“CODM”), to evaluate segment performance, the availability of separate financial information, and overall materiality considerations. Effective as of the acquisition of SOC on August 21, 2025, our business divisions are organized into the following four reportable segments, reflecting the manner in which our CODM assesses performance and allocates resources:

1. Building Solutions

2. Business Services

3. Energy Services

4. Investments

Our reporting segments have been determined based on the nature of the products and services offered to customers or the nature of their function in the organization. We evaluate performance based on gross profit and operating income (loss). Our operating costs included in our shared service functions primarily consist of senior executive officers, finance, human resources, legal, and information technology. Star Equity shared service corporate costs have been separated from the reportable segments. Prior period presentation previously disclosed conforms to current year presentation.

• 36 -

Segment information for the three and nine months ended September 30, 2025 and 2024, respectively, is as follows:

• 37 -

(a)Gross profit in the Business Services segment includes the direct staffing costs of salaries, payroll taxes, employee benefits, travel expenses, and insurance costs for the Company’s contractors and reimbursed out-of-pocket expenses and other direct costs. The region where services are provided, the mix of RPO and contracting, and the functional nature of the staffing services provided can affect operating income and EBITDA. The salaries, commissions, payroll taxes, and employee benefits related to recruitment professionals are included under the caption “Salaries and related” in the Condensed Consolidated Statements of Operations.

(b)SEC Regulation S-K Item 229.10(e)1(ii)(A) defines EBITDA as earnings before interest, taxes, depreciation and amortization. EBITDA is presented to provide additional information to investors about the Company’s operations on

• 38 - a basis consistent with the measures that the Company uses to manage its operations and evaluate its performance. Management also uses this measurement to evaluate working capital requirements. EBITDA should not be considered in isolation or as a substitute for operating income and net income prepared in accordance with U.S. GAAP or as a measure of the Company’s profitability.

(c)Comprised of property and equipment, intangible assets and goodwill, net of accumulated depreciation and amortization.

Geographic Data Reporting

A summary of revenues for the three and nine months ended September 30, 2025 and 2024 and net assets by geographic area as of September 30, 2025 and 2024 and as of December 31, 2024, were as follows:

(a) Revenue by geographic region disclosed above is net of any inter-segment revenue and, therefore, represents only revenue from external customers according to the location of the operating subsidiary.

Notes Receivable

Notes receivable consists of the following principal and interest balances as of September 30, 2025:

As a part of the sale of Digirad Health in May 2023, SOC entered into a $7,000 promissory note (the “Catalyst Note”) which represents an unsecured note receivable on our balance sheet.

Long Term Investments

Below are the components of our Long Term Investments as of September 30, 2025:

Investment in Catalyst

As a part of the sale of Digirad Health, SOC received common equity of Catalyst Parent, which is held in our Investments Segment at a fair value of $953 at September 30, 2025. We have elected the measurement alternative under ASC 321, Investments-Equity Securities. The measurement alternative election allows for equity securities that do not have readily determinable fair values to be recorded at cost, with adjustments for impairment and certain observable price changes reflected in earnings. Such securities are adjusted to fair value when an observable price change occurs or impairment is identified.

Investment in Enservco

On August 9, 2024, SOC entered into an investment in Enservco pursuant to a Share Exchange Agreement in which SOC agreed to issue to Enservco 250,000 shares of 10% Series A Cumulative Perpetual Preferred Stock representing $2,600 of value in exchange for 9,023,035 Enservco Common Shares, representing 19.9% of the equity interests of Enservco, and 3.5 million Enservco Preferred Shares and certain options included in the Share Exchange Agreement. Enservco also agreed to appoint one Company representative to the Enservco board of directors. We also issued a $1,000 Note to Enservco to facilitate Enservco’s acquisition of Buckshot Trucking, LLC.

We hold the Investment in Enservco in the Investments Segment. As of September 30, 2025, we owned 9.0 million shares of Enservco Common Stock, representing approximately 15.5% of Enservco’s outstanding common stock, and 3.5 million shares of Mandatorily Convertible Preferred Stock representing approximately 22.0% of the total outstanding Enservco Common Stock assuming all preferred stock was converted.

NOTE 19 –CASH, CASH EQUIVALENTS, AND RESTRICTED CASH

Cash, cash equivalents, and restricted cash as reported within the accompanying Condensed Consolidated Balance Sheets as of September 30, 2025 and December 31, 2024 was as follows:

• 41 -

Restricted cash primarily includes lease and collateral deposits, as well as bank guarantees for licensing.

NOTE 20 –COMMITMENTS AND CONTINGENCIES

Litigation and Complaints

The Company is subject, from time to time, to various claims, lawsuits, contracts disputes, and other complaints from, for example, clients, candidates, suppliers, landlords for both leased and subleased properties, former and current employees, and regulators or tax authorities arising in the ordinary course of business. The Company routinely monitors claims such as these, and records provisions for losses when the claim becomes probable and the amount due is estimable. Although the outcome of these claims cannot be determined, the Company believes that the final resolution of these matters will not have a material adverse effect on the Company’s financial condition, results of operations or liquidity.

For matters that reach the threshold of probable and estimable, the Company establishes reserves for legal, regulatory, and other contingent liabilities. The Company did not have any legal reserves as of September 30, 2025 and December 31, 2024.

In the normal course of business, we have been and will likely continue to be subject to litigation or administrative proceedings incidental to our business, such as claims related to compliance with regulatory standards, customer disputes, employment practices, wage and hour disputes, product liability, professional liability, malpractice liability, commercial disputes, licensure restrictions or denials, and warranty or patent infringement. Responding to litigation or administrative proceedings, regardless of whether they have merit, can be expensive and disruptive to normal business operations. We are not able to predict the timing or outcome of these matters but currently do not expect that the resolution of these matters will have a material adverse effect on our financial position or results of operations.

The outcome of litigation and the amount or range of potential loss at particular points in time may be difficult to ascertain. Among other things, uncertainties can include how trial and appellate courts will apply the law and interpret facts, as well as the contractual and statutory obligations of other indemnifying and insuring parties. The estimated range of reasonably possible losses, and their effect on our financial position is based on currently available information and is subject to significant judgment and a variety of assumptions, as well as known and unknown uncertainties.
