Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Policies	Basis of Presentation and Significant Policies Basis of Presentation The unaudited condensed consolidated financial statements included in this Form 10-Q have been prepared in accordance with the U.S. Securities and Exchange Commission (the “SEC”) instructions for Quarterly Reports on Form 10-Q. Accordingly, the condensed consolidated financial statements are unaudited and do not contain all the information required by U.S. generally Accepted Accounting Principles (“GAAP”) to be included in a full set of financial statements. The unaudited condensed consolidated balance sheet at December 31, 2021 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for a complete set of financial statements. The audited consolidated financial statements for our fiscal year ended December 31, 2021, filed with the SEC on Form 10-K on March 31, 2022, include a summary of our significant accounting policies and should be read in conjunction with this Form 10-Q. In the opinion of management, all material adjustments necessary to present fairly the results of operations, cash flows, and balance sheets for such periods have been included in this Form 10-Q. All such adjustments are of a normal recurring nature. The results of operations for interim periods are not necessarily indicative of the results of operations for the entire year. The Company and Discontinued Operations On March 31, 2021, Star Equity Holdings, Inc. (“Star Equity,” the “Company,” “we,” or “our”), a diversified holding company with three divisions: Healthcare, Construction, and Investments, announced the completion of the sale of DMS Health Technologies, Inc., a North Dakota corporation and wholly owned indirect subsidiary of Star Equity (“DMS Health”), for $18.75 million in cash, as originally announced on November 3, 2020 (the “DMS Sale Transaction”). The assets and liabilities of DMS Health were previously classified as held for sale and the results of DMS Health’s operations were presented as a discontinued operations in our previously issued financial statements. Unless otherwise noted, discussion within these notes to the condensed consolidated financial statements relates to continuing operations. Refer to Note 2. Discontinued Operations for additional information. Mezzanine and Permanent Equity Pursuant to the Certificate of Designations, Rights and Preferences of 10% Series A Cumulative Perpetual Preferred Stock (the “Series A Preferred Stock”) of Star Equity (formerly Digirad Corporation) (the “Certificate of Designations”), upon a Change of Control Triggering Event, as defined in the Certificate of Designations, holders of the Series A Preferred Stock had the ability to require the Company to redeem the Series A Preferred Stock at a price of $10.00 per share, plus any accumulated and unpaid dividends (a “Change of Control Redemption”). As this redemption feature of the shares was not solely within the control of the Company, the Series A Preferred Stock did not qualify as permanent equity and was classified as mezzanine or temporary equity. The Series A Preferred Stock was not redeemable and it was not probable that our Series A Preferred Stock would become redeemable as of December 31, 2021. Therefore, we were not previously required to accrete the Series A Preferred Stock to its redemption value. On June 2, 2022, the Certificate of Designations was amended to include a “Special Optional Redemption Right” at the Company’s discretion and to extinguish the option of preferred stockholders to redeem preferred shares upon a Change of Control Triggering Event, as defined in the Certificate of Designations, as amended. As the redemption features of the Series A Preferred Stock are now solely within the control of the Company, the Series A Preferred Stock qualifies as permanent equity and has been reclassified to permanent equity effective June 2, 2022. In addition to the foregoing redemption features, the Certificate of Designations also provides that we may redeem (at our option, in whole or in part) the Series A Preferred Stock following the fifth anniversary of issuance of the Series A Preferred Stock, at a cash redemption price of $10.00 per share, plus any accumulated and unpaid dividends. On February 25, 2022 and May 19, 2022, our board of directors declared cash dividends to holders of our Series A Preferred Stock of $0.25 per share, for an aggregate amount of approximately $1.0 million. The record dates for these dividends were March 1, 2022 and June 1, 2022, respectively, and the payment dates were March 10, 2022 and June 10, 2022, respectively Refer to preferred stock dividends discussed in Note 13. Perpetual Preferred Stock. Going Concern The accompanying condensed consolidated financial statements have been prepared assuming we will continue as a going concern, which contemplates the realization of assets and settlement of obligations in the normal course of business. We incurred losses from continuing operations, net of income taxes, of approximately $1.6 million and $5.3 million for the three and six months ended June 30, 2022, respectively, and $1.8 million and $2.4 million for the three and six months ended June 30, 2021, respectively. We have an accumulated deficit of $133.2 million and $128.0 million as of June 30, 2022 and December 31, 2021, respectively. As of June 30, 2022, cash and cash equivalents increased to $13.7 million from $4.5 million as of December 31, 2021, primarily as a result of an underwritten public offering (the “2022 Public Offering”) which closed on January 24, 2022. Refer to Note 14. Equity Transactions for details. At June 30, 2022, we had approximately $11.6 million in debt outstanding. All of our debt is categorized as short-term on our condensed Consolidated Balance Sheets. For more detail, see Note 8. Debt . The Company’s loan pursuant to the Webster Loan Agreement (as defined below) (the “Webster Loan”) with Webster Bank, N.A., a national banking association as lender (“Webster”), as successor in interest to Sterling National Bank, with a loan balance of approximately $8.1 million, supports our Healthcare business. While the Webster Loan matures in 2024, GAAP rules require that the outstanding balance be classified as short-term debt. This is due to both the automatic sweep feature embedded in the traditional lockbox arrangement and the subjective acceleration clause in the Webster Loan Agreement. As of June 30, 2022, we were not in compliance with covenants in the Webster Loan Agreement related to our Healthcare division and we have not yet obtained a waiver from Webster for these financial covenant breaches. Upon the occurrence and during the continuation of an event of default under the Webster Loan Agreement, Webster may, among other things, declare the loans and all other obligations under the Webster Loan Agreement immediately due and payable and increase the interest rate at which loans and obligations under the Webster Loan Agreement bear interest. We are currently in negotiations to avoid a default. While we do not believe we will be required to pay down the current balance, our current cash is sufficient to repay the Webster Loan in full. Management has historically concluded that this forecasted violation raises substantial doubt about our ability to continue as a going concern within twelve months. In consideration of the cash flow results for the six months ended June 30, 2022, our current balance of cash and cash equivalents of $13.7 million and our projected use of cash for the next twelve months, management believes that the Company's existing cash and current free cash flow generation expectations will allow the Company to continue its operations for at least the next 12 months from the date these unaudited condensed financial statements are issued, even in the event that we are requested to pay some or all of the outstanding Webster Loan balance. Therefore, the conditions that led us to conclude substantial doubt in prior periods have been alleviated. As a result of recurring losses, the continued viability of the Company beyond August 2023 may be dependent on its ability to continue to raise additional capital to finance its operations. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and disclosures made in the accompanying notes to the condensed consolidated financial statements. Significant estimates and judgments include those related to revenue recognition, goodwill valuation, and income taxes. Actual results could materially differ from those estimates. Revenue Recognition We recognize revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606 and Topic 842. Pursuant to ASC 606, Revenue from Contracts with Customers , we recognize revenue when a customer obtains control of promised goods or services. We record the amount of revenue that reflects the consideration that it expects to receive in exchange for those goods or services. We apply the following five-step model in order to determine this amount: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company has elected to use the practical expedient under ASC 606 to exclude disclosures of unsatisfied remaining performance obligations for (i) contracts having an original expected length of one year or less or (ii) contracts for which the practical expedient has been applied to recognize revenue at the amount for which it has a right to invoice. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue. The majority of our contracts have a single performance obligation, as we provide a series of distinct goods or services that are substantially the same and are transferred with the same pattern to the customer. For contracts with multiple performance obligations, we allocate the total transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. We use an observable price to determine the stand-alone selling price for separate performance obligations or a cost plus margin approach when one is not available. 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 recognition is evaluated on a contract by contract basis. Performance obligations are satisfied over time as work progresses or at a point in time. A performance obligation is satisfied over time if we have an enforceable right to payment. Determining if there is an enforceable right to payment is assessed on a contract by contract basis. For contracts requiring over time revenue recognition, the selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We use a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress towards completion is measured based on the costs incurred to date. Our products are generally not sold with a right of return and the Company does not provide significant credits or incentives, which may be variable consideration when estimating the amount of revenue to be recognized. Healthcare Services Revenue Recognition. We generate service revenue primarily from providing diagnostic services to our customers. Service revenue within our Healthcare reportable segment is derived from providing our customers with contract diagnostic services, which includes use of our imaging systems, qualified personnel, radiopharmaceuticals, licensing, logistics and related items required to perform testing in their own offices. We bill customers either on a per-scan or fixed-payment methodology, depending upon the contract that is negotiated with the customer. Within our Healthcare segment, we also rent cameras to healthcare customers for use in their operations. Rental revenues are structured as either a weekly or monthly payment arrangement, and are recognized in the month rental assets are provided. Revenue related to provision of our services is recognized at the time services are performed. Healthcare Product and Product-Related Revenue Recognition. We generate revenue from product and product-related sales, primarily from the sale of gamma cameras, accessories, and radiopharmaceuticals doses. Healthcare product revenues are generated from the sale of internally developed solid-state gamma camera imaging systems and post-warranty camera maintenance service contracts. Revenue from sales of imaging systems is generally recognized at point in time upon delivery of systems and acceptance by customers. We also provide installation services and training on cameras sold, primarily in the United States. Installation and initial training is generally performed shortly after delivery and the revenue related to the provision of these services is recognized at the time services are performed. Neither installation nor training is essential to the functionality of the product. Finally, we offer camera maintenance service contracts that are sold beyond the term of the initial warranty, generally one year from the date of purchase. Revenue from these service contracts is deferred and recognized ratably over the period of the obligation. We offer time and material services and record revenue when service is performed. Radiopharmaceuticals doses revenue, generated by Healthcare, is generally recognized when delivered to the customer. Construction Revenue Recognition. Our Construction division is made up of three operating businesses, KBS Builders, Inc. (“KBS”), EdgeBuilder, Inc. (“EdgeBuilder”), and Glenbrook Building Supply, Inc. (“Glenbrook”)—with the latter two managed together and referred to jointly as “EBGL”. KBS, EdgeBuilder and Glenbrook are wholly owned subsidiaries of Star Equity and are referred to collectively herein, and together with ATRM Holdings, Inc. (“ATRM”), as the “Construction Subsidiaries.” Within the Construction division, we service residential and commercial construction projects by manufacturing modular housing units and other products and supply general contractors with building materials. 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. 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 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 classified in deferred revenue in the condensed Consolidated Balance Sheets. Contract liabilities are reduced when the associated revenue from the contract is recognized, which is generally within one year. Contract Assets. 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 costs to obtain a contract when the amortization period would have been one year or less. These costs mainly include the internal sales commissions; under the terms of these programs these are generally earned and the costs are recognized at the time the revenue is recognized. Deferred Revenue We record deferred revenue when cash payments are received in advance of our performance. We have determined our contracts do not include a significant financing component. The majority of our deferred revenue relates to payments received on camera support post-warranty service contracts, which are billed at the beginning of the contract period or at periodic intervals (e.g., monthly, quarterly, or annually). Leases Lessee Accounting We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities, and operating lease liabilities, net of current portion in our condensed consolidated balance sheets. Finance leases are included in property and equipment, finance lease liabilities, net of current portion, and finance lease liabilities in our condensed Consolidated Balance Sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use the implicit discount rate when readily determinable; however, as most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The ROU asset also includes any lease payments made and excludes lease incentives. Our lease valuation may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. We elected not to separate lease and non-lease components of our leases in which we are the lessee and lessor. Additionally, we elected not to recognize right-of-use assets and leases liabilities that arise from short-term leases of twelve months or less. Lessor Accounting The majority of the lease income of the Healthcare division comes from camera rentals and the lease income of the Construction division comes from the rental of the Waterford facility to a commercial tenant. We determine lease classification at the commencement date. Leases not classified as sales-type or direct financing leases are classified as operating leases. The primary accounting criteria we use for lease classification are (a) review to determine if the lease transfers ownership of the underlying asset to the lessee by the end of the lease term, (b) review to determine if the lease grants the lessee a purchase option that the lessee is reasonably certain to exercise, (c) determine, using a seventy-five percent or more threshold, if the lease term is for a major part of the remaining economic life of the underlying asset (however, we do not use this classification criterion when the lease commencement date falls within the last 25 percent of the total economic life of the underlying asset) and (d) determine, using a 90 percent or more threshold, if the present value of the sum of the lease payments and any residual value guarantees equal or exceeds substantially all of the fair value of the underlying asset. We do not lease equipment of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. Each of our leases is classified as an operating lease. We elected the operating lease practical expedient for its leases to not separate non-lease components of regular maintenance services from associated lease components. This practical expedient is available when both of the following are met: (i) the timing and pattern of transfer of the non-lease components and associated lease component are the same and (ii) the lease component, if accounted for separately, would be classified as an operating lease. Property taxes paid by the lessor that are reimbursed by the lessee are considered to be lessor costs of owning the asset, and are recorded gross with revenue included in other non-interest income and expense recorded in operating expenses. We selected a lessor accounting policy election to exclude from revenue and expenses sales taxes and other similar taxes assessed by a governmental authority on lease revenue-producing transactions and collected by the lessor from a lessee. Operating lease equipment is carried at cost less accumulated depreciation. Operating lease equipment is depreciated to its estimated residual value using the straight-line method over the lease term or estimated useful life of the asset. Rental revenue on operating leases is recognized on a straight-line basis over the lease term unless collectability is not probable. In these cases, rental revenue is recognized as payments are received. Concentration of Credit Risk Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable. We limit our exposure to credit loss by generally placing cash in high credit quality financial institutions. Cash balances are maintained primarily at major financial institutions in the United States and a portion of which exceed the regulatory limit of $250,000 insured by the Federal Deposit Insurance Corporation (FDIC). We have not experienced any credit losses associated with our cash balances. Additionally, we have established guidelines regarding diversification of our investments and their maturities, which are designed to maintain principal and maximize liquidity. Variable Interest Entities We determine at the inception of each arrangement whether an entity in which we have made an investment or in which we have other variable interests is considered a variable interest entity (“VIE”). We consolidate VIEs when we are the primary beneficiary. We are the primary beneficiary of a VIE when we have the power to direct activities that most significantly affect the economic performance of the VIE and have the obligation to absorb the significant losses or benefits. If we are not the primary beneficiary in a VIE, we account for the investment or other variable interests in a VIE in accordance with applicable GAAP. Periodically, we assess whether any changes in our interest or relationship with the entity affect our determination of whether the entity is a VIE and, if so, whether we are the primary beneficiary. Reclassification PPP Loan forgiveness reclassification has been made to the prior period financial statements to conform to the current year financial statement presentation of the condensed Consolidated Statements of Operations. This change did not impact previously reported net loss, loss per share, stockholders’ equity, total assets or the condensed Consolidated Statements of Cash Flows. Finance Lease liabilities and Investments reclassifications have been made to the prior period financial statements to conform to the current year financial statement presentation of the condensed Consolidated Balance Sheets. These changes did not impact previously reported net (loss) income, (loss) income per share, stockholders’ equity, total liabilities, total assets or the condensed Consolidated Statements of Cash Flows. Other reclassifications have been made to the current period financial statement presentation of the condensed Consolidated Balance Sheets. These changes did not impact previously reported net loss, loss per share, stockholders’ equity, total assets or the condensed Consolidated Statements of Cash Flows. New Accounting Standards To Be Adopted No new accounting standards were issued in the quarter ended June 30, 2022 that are expected to have a material impact on our financial statements. Recently Adopted Accounting Standards No accounting standards were adopted in the quarter ended June 30, 2022 that are expected to have a material impact on our financial statements.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On October 30, 2020, Star Equity entered into a Stock Purchase Agreement (the “DMS Purchase Agreement”) between the Company (“Seller”), DMS Health, and Knob Creek Acquisition Corp., a Tennessee corporation (“Buyer”), pursuant to which the Buyer purchased all of the issued and outstanding common stock of DMS Health, which operated our Mobile Healthcare business unit, from Seller. The purchase price under the DMS Purchase Agreement was $18.75 million in cash, subject to certain adjustments, including a working capital adjustment. The transactions closed effective March 31, 2021. We deemed the disposition of the Mobile Healthcare business unit to represent a strategic shift that will have a major effect on our operations and financial results. For the year ended December 31, 2021, the Mobile Healthcare business met the criteria to be classified as held for sale. We allocated a portion of interest expense to discontinued operations since the proceeds received from the sale were required to be used to pay down outstanding borrowings under our revolving credit facility under the Webster Loan Agreement. The allocation was based on the ratio of assets generated based on the borrowing capacity to total borrowings capacity for the period. In addition, certain general and administrative costs related to corporate and shared service functions previously allocated to the mobile healthcare reportable segment are included in discontinued operations. The following table presents financial results of DMS Health for the three and six months ended June 30, 2021. There have been no activities for the six months ended June 30, 2022 (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2021 2021 Total revenues $ — $ 9,490 Total cost of revenues — 6,973 Gross profit — 2,517 Operating expenses: Selling, general and administrative — 1,469 Total operating expenses — 1,469 Income from discontinued operations — 1,048 Interest expense, net — (180) (Loss) Gain on sale of discontinued operations (65) 5,159 (Loss) Income from discontinuing operations before income taxes (65) 6,027 Income tax expense — (72) (Loss) Income from discontinuing operations $ (65) $ 5,955 The following table presents the significant non-cash operating, investing and financing activities from discontinued operations for the six months ended June 30, 2021 (in thousands): Six Months Ended June 30, 2021 Operating activities Depreciation $ 7 Non-cash lease expense 256 Write-off of borrowing costs 130 Gain on sale of DMS discontinued operations (5,159) Investing activities Purchase of property and equipment (154) Proceeds from sale of discontinued operations 18,750 Proceeds from sale of property and equipment 3 Following is the reconciliation of purchase price to the gain recognized in income from discontinued operations for the six months ended June 30, 2021 (in thousands): Estimated proceeds of the disposition, net of transaction costs $ 18,750 Assets of the businesses (20,920) Liabilities of the businesses 7,712 Transaction expenses (383) Pre-tax gain on the disposition $ 5,159 In April 2021, DMS Health contracted Digirad Imaging Solutions for a term of three years to purchase radiopharmaceuticals doses, resulting in $0.7 million of revenues for the six months ended June 30, 2022.

For the six months ended June 30, 2021, the amount of $1.9 million was revised from over time to point in time related to revenue recognition in the table above. Healthcare for goods transferred over time decreased by $1.9 million, with a corresponding increase to revenue recognized for goods and services transferred at a point in time. The adjustments did not impact the total amount of revenue or the period in which it was recognized, therefore, they had no effect on the condensed Consolidated Balance Sheets, Statements of Operations and Cash Flows for the periods presented. Nature of Goods and Services Mobile Imaging Within our Healthcare segment, our sales are derived from providing services and materials to our customers, primarily physician practices and hospitals that allow them to perform diagnostic services at their site. We typically bundle our services in providing staffing, our imaging systems, licensing, radiopharmaceuticals, and supplies depending on our customers’ needs. Our contracts with customers are typically entered into annually and are billed on a fixed rate per-day or per-scan basis, depending on terms of the contract. For the majority of these contracts, we have the right to invoice the customer in an amount that directly corresponds with the value to the customer as we perform the services. We use the practical expedient to recognize revenue corresponding with amounts we have the right to invoice for services performed. Camera Within our Healthcare segment, camera revenues are generated from the sale of internally developed solid-state gamma camera imaging systems and accessories. We recognize revenue upon transfer of control to the customer at a point-in-time, which is generally upon delivery and acceptance. We also provide installation services and training on cameras we sell, primarily in the United States. Installation and initial training is generally performed shortly after delivery. We recognize revenues for installation and training over time as the customer receives and consumes benefits provided as we perform the installation services. Our sale of imaging systems includes a one-year assurance-type warranty. The estimated costs associated with our standard warranties and field service actions continue to be recognized as expense when cameras are sold. Maintenance service contracts sold beyond the term of our standard warranties are accounted for as a service-type warranty and revenue is deferred and recognized ratably over the period of the warranty obligation. Camera Support Within our Healthcare segment, camera support revenue is derived from the sale of separately-priced extended maintenance contracts to camera owners, training, and the sale of parts to customers that do not have an extended warranty. Our separately priced service contracts range from 12 to 48 months. Service contracts are usually billed at the beginning of the contract period or at periodic intervals (e.g., monthly, quarterly, or annually) and revenue is recognized ratably over the term of the agreement. Services and training revenues are recognized in the period the services and training are performed. Revenue for sales of parts are recognized when the parts are delivered to the customer and control is transferred. Lease Income Within our Healthcare segment, we also generate income from rentals of state-of-the-art equipment including cameras and ultrasound machines to customers. Rental contracts are structured as either a weekly or monthly payment arrangement and are accounted for as operating leases. Revenues are recognized on a straight-line basis over the term of the rental. Construction Within the Construction segment, we service residential and commercial construction projects by manufacturing modular housing units and other products and supply general contractors with building materials. 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. Revenues are evaluated on a contract by contract basis. In general, construction revenues are recognized upon transfer of control to the customer at a point-in-time, which is generally upon delivery and acceptance. However, construction revenues are recognized over time for arrangements with customers for which: (i) performance does not create an asset with an alternative use, and (ii) we have an enforceable right to payment for performance completed to date. Deferred Revenue Changes in the deferred revenue for six months ended June 30, 2022, is as follows (in thousands): Balance at December 31, 2021 $ 2,869 Revenue recognized that was included in balance at beginning of the year (1,664) Deferred revenue, net, related to contracts entered into during the year 2,995 Balance at June 30, 2022 $ 4,200 As of June 30, 2022 and December 31, 2021, non-current deferred revenue was $360 thousand and $412 thousand, respectively, in other liabilities within our condensed Consolidated Balance Sheets, which is expected to be recognized over a period of 2-4 years. Billings in Excess of Costs and Estimated Profit Changes in the billings in excess of costs and estimated profit for six months ended June 30, 2022 is as follows (in thousands): Balance at December 31, 2021 $ 312 Revenue recognized that was included in balance at beginning of the year (312) Billings in excess of costs, related to contracts entered into during the year 2,181 Balance at June 30, 2022 $ 2,181 Contract Assets There were no contract assets as of June 30, 2022 and December 31, 2021.

Basic and Diluted Net Income (L

Basic and Diluted Net Income (Loss) Per Share	6 Months Ended
	Jun. 30, 2022
Earnings Per Share [Abstract]
Basic and Diluted Net Income (Loss) Per Share	Basic and Diluted Net Income (Loss) Per Share We present net income (loss) per share attributable to common stockholders in conformity with the two-class method required for participating securities, as the warrants are considered participating securities. We have not allocated net loss attributable to common stockholders to warrants because the holders of our warrants are not contractually obligated to share in our losses. Basic net loss per share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per share attributable to common stockholders is calculated to give effect to all potential shares of common stock, including common stock issuable upon exercise of warrants, stock options, and restricted stock units (“RSUs”). In periods for which there is a net income, diluted income per common share is equal to basic income per common share, since the effect of including any common stock equivalents would be antidilutive. The following table sets forth the reconciliation of shares used to compute basic and diluted net (loss) or income per share for the periods indicated (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Numerator: Loss from continuing operations, net of tax $ (1,576) $ (1,791) $ (5,277) $ (2,379) (Loss) income from discontinued operations, net of tax — (65) — 5,955 Net (loss) income (1,576) (1,856) (5,277) 3,576 Deemed dividend on Series A perpetual preferred stock (479) (479) (958) (958) Net (loss) income attributable to common shareholders $ (2,055) $ (2,335) $ (6,235) $ 2,618 Denominator: Weighted average common shares outstanding 15,054 5,039 13,751 4,978 Weighted average prefunded warrants outstanding 325 — 280 — Weighted average shares outstanding - basic and diluted 15,379 5,039 14,031 4,978 Net (loss) income per share—basic and diluted Net loss per share, continuing operations $ (0.10) $ (0.36) $ (0.38) $ (0.48) Net (loss) income per share, discontinued operations $ — $ (0.01) $ — $ 1.20 Net (loss) income per share—basic and diluted* $ (0.10) $ (0.37) $ (0.38) $ 0.72 Deemed dividend on Series A cumulative perpetual preferred stock per share $ (0.03) $ (0.10) $ (0.07) $ (0.19) Net (loss) income per share, attributable to common shareholders—basic and diluted* $ (0.13) $ (0.46) $ (0.44) $ 0.53 *Earnings per share may not add due to rounding Antidilutive common stock equivalents are excluded from the computation of diluted loss per share.

Warranty Reserves In our Healthcare division, we generally provide a 12-month assurance warranty on our gamma cameras. We accrue the estimated cost of this warranty at the time revenue is recorded and charge warranty expense to product and product-related cost of revenues. Warranty reserves are established based on historical experience with failure rates and repair costs and the number of systems covered by warranty. Warranty reserves are depleted as gamma cameras are repaired. The costs consist principally of materials, personnel, overhead, and transportation. We review warranty reserves quarterly and make adjustments, as necessary. Within our Construction 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 twenty-five years.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Assets and Liabilities Measured at Fair Value on a Recurring Basis 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. Level 1 inputs are quoted prices in active markets for identical assets; Level 2 inputs are inputs other than quoted prices that are significant and observable; and Level 3 inputs are significant unobservable inputs to be used in situations where markets do not exist or illiquid. The following table presents information about our financial assets that are measured at fair value on a recurring basis, and indicates the fair value hierarchy of the valuation techniques we utilize to determine such fair value at June 30, 2022 and December 31, 2021 (in thousands): Fair Value as of June 30, 2022 Level 1 Level 2 Level 3 Total Assets (Liabilities): Equity securities $ 2,550 $ — $ — $ 2,550 Lumber derivative contracts (482) — — (482) VIE Investments — — 337 337 Total $ 2,068 $ — $ 337 $ 2,405 Fair Value as of December 31, 2021 Level 1 Level 2 Level 3 Total Assets (Liabilities): Equity securities $ 47 $ — $ — $ 47 Lumber derivative contracts 666 — — 666 VIE Investments — — 337 337 Total $ 713 $ — $ 337 $ 1,050 The investment in equity securities consists of common stock of publicly traded companies. The fair value of these securities is based on the closing prices observed on June 30, 2022 and December 31, 2021, respectively, and recorded in Investments in the Consolidated Balance Sheets. During the six months ended June 30, 2022 and 2021, we recorded an unrealized gain of $235 thousand and unrealized loss of $33 thousand, respectively, recorded in other (expense) income, net in the condensed Consolidated Statements of Operations. We may enter into lumber derivative contracts in order to protect our gross profit margins from fluctuations caused by volatility in lumber price, recorded within current assets or liabilities in the Consolidated Balance Sheets. For the six months ended June 30, 2022 and 2021, we recorded a net loss of $1.1 million and $0.3 million, respectively, in the cost of goods sold in the condensed Consolidated Statements of Operations. As of June 30, 2022, we had a net long (buying) position of 3,630,000 board feet under 33 lumber derivatives contracts. As of December 31, 2021, we had a net long (buying) position of 2,420,000 board feet under 22 lumber derivatives contracts. Gains and losses from lumber derivative contracts, are recorded in cost of goods sold of the condensed Consolidated Statements of Operations and included the following: June 30, 2022 June 30, 2021 Amount Amount Unrealized loss on lumber derivatives $ 1,145 $ 241 Realized (gain) loss on lumber derivatives (17) 62 Total loss on lumber derivatives $ 1,128 $ 303 The fair value of VIE investments of $0.3 million recorded in Other Assets in the Consolidated Balance Sheets is based on unobservable inputs evaluated on June 30, 2022 and December 31, 2021, respectively.

On February 1, 2022, Sterling became part of Webster, and Webster became the successor in interest to the Webster Loan Agreement. The Webster Loan Agreement is also subject to a limited guarantee by Mr. Eberwein, the Executive Chairman of our board of directors. The Webster Loan Agreement is a five-year credit facility maturing in March 2024, with a maximum credit amount of $20.0 million for revolving loans (the “Webster Credit Facility”). Under the Webster Credit Facility, the Webster Borrowers can request the issuance of letters of credit in an aggregate amount not to exceed $0.5 million at any one time outstanding. The borrowings under the Webster Loan Agreement were classified as short-term obligations under GAAP as the agreement contained a subjective acceleration clause and required a lockbox arrangement whereby all receipts within the lockbox are swept daily to reduce borrowings outstanding. As of June 30, 2022, the Company had $0.1 million of letters of credit outstanding and had additional borrowing capacity of $0.1 million under the Webster Credit Facility. At the Webster Borrowers’ option, the Webster Credit Facility will bear interest at either (i) a Floating LIBOR Rate, as defined in the Webster Loan Agreement, plus a margin of 2.50% per annum; or (ii) a Fixed LIBOR Rate, as defined in the Webster Loan Agreement, plus a margin of 2.25% per annum. Our floating rate on this facility at June 30, 2022 was 4.29%. The Webster Loan Agreement also provides for unused line fees and restricts the usage of borrowings under the line solely to support the Healthcare businesses, subject to certain limitations. The Webster Credit Facility is secured by the assets of the Digirad Health businesses. Financial covenants require that the Webster Borrowers maintain (a) a Fixed Charge Coverage Ratio as of the last day of a fiscal quarter of not less than 1.25 to 1.0 and (b) a Leverage Ratio as of the last day of such fiscal quarter of no greater than 3.50 to 1.0. As of June 30, 2022, the Company was not in compliance with the covenants under the Webster Loan Agreement and had not yet obtained a waiver from Webster for these financial covenant breaches. eCapital Credit Facilities EdgeBuilder and Glenbrook (the “EBGL Borrowers”) are a party to a revolving credit facility with eCapital Asset Based Lending Corp., formerly known as Gerber Finance Inc. (“eCapital”) (the “EBGL Loan Agreement”). The facility, as amended, provides for borrowings up to $4.0 million, subject to certain borrowing base limitations. As of June 30, 2022, EBGL was fully drawn in terms of available borrowing capacity available under the facility. Amounts outstanding bear interest, payable monthly, at the prime rate plus 2.75% and payments of outstanding principal are due in full upon maturity. The facility is subject to annual renewal and is currently set to mature on the earlier of January 31, 2023 or upon repayment of the Star Loan (see below). The facility is secured by substantially all of the assets of EBGL and borrowings under the line are restricted for use to finance the operations of EBGL. As of June 30, 2022, $2.5 million was outstanding under the EBGL Loan Agreement. As of June 30, 2022, EBGL was not in compliance with the bi-annual financial covenants under the EBGL Loan Agreement measured as of June 30, 2022. As of June 30, 2022, we obtained a waiver from eCapital for financial covenant breaches. However, there can be no assurance that we will be able to obtain such waivers in the event of future financial covenant violations. On March 8, 2022, the EBGL Borrowers entered into the Seventh Amendment to the EBGL Loan Agreement with eCapital to amend and lower the financial covenants to require that EBGL maintain (a) a lower net cash income (as defined in the EBGL Loan Agreement) at least equal to no less than $0 for the trailing 6-month period ending June 30, 2022 and no less than $1,000,000 for the trailing fiscal year ending December 31, 2022 and (b) a reduced minimum EBITDA (as defined in the EBGL Loan Agreement) to be no less than $0 as of June 30, 2022 and no less than $1,000,000 as of the fiscal year ending December 31, 2022. KBS is a party to a revolving credit facility with eCapital (“KBS Loan Agreement”). The facility, as amended, provides for borrowings up to $4.0 million, subject to certain borrowing base limitations. As of June 30, 2022, KBS was fully drawn in terms of available borrowing capacity under the facility. Amounts outstanding bear interest, payable monthly, at the prime rate plus 2.75% and payments of outstanding principal are due in full upon maturity. The facility is subject to annual renewal and is currently set to mature on February 22, 2023. The facility is secured by the assets of KBS and borrowings under the line are restricted for use to finance the operations of KBS. As of June 30, 2022, no amount was outstanding under the KBS Loan Agreement. As of June 30, 2022, KBS was in compliance with the bi-annual financial covenants under the KBS Loan Agreement. The eCapital credit facilities contain cross-default provisions and subjective acceleration clauses which may, in the event of a material adverse event, as determined by eCapital, allow eCapital to declare the loans immediately due and payable or increase the interest rate. The facilities are also subject to a guaranty by the Company and the Company is responsible for certain facility and other fees. Borrowings under the eCapital credit facilities are classified as short-term obligations as the agreements contain a subjective acceleration clauses and require a lockbox arrangement whereby all receipts within the lockbox are swept daily to reduce borrowings outstanding. On March 8, 2022, the borrowers under the KBS Loan Agreement entered into the Nineteenth Amendment to the KBS Loan Agreement to amend the financial covenants to require that KBS maintain (a) net cash income (as defined in the KBS Loan Agreement) of at least equal to no less than $0 for the trailing 6-month period ending June 30, 2022 and be no less than $500,000 for the trailing fiscal year end and (b) a minimum EBITDA (as defined in the KBS Loan Agreement) no less than $0 as of June 30, 2022 and no less than $850,000 as of the fiscal year end, as well as a waiver of certain covenants as of December 31, 2021. Term Loan We and certain of our Investments subsidiaries (collectively, the “Star Borrowers”) are party to a Loan and Security Agreement with eCapital, as successor in interest to Gerber Finance, Inc. (as amended, the “Star Loan Agreement”), which provides for a credit facility with borrowing availability of up to $2.5 million, bearing interest at the prime rate plus 3.5% per annum, and matures on January 1, 2025, unless terminated in accordance with the terms therein (the “Star Loan”). The following table presents the Star Loan balance, net of unamortized debt issuance costs as of June 30, 2022 (in thousands): June 30, 2022 December 31, 2021 Amount Amount eCapital - Star Loan Principal $ 1,060 $ 1,246 Unamortized debt issuance costs (123) (176) eCapital - Star Loan Principal, net $ 937 $ 1,070 The Star Loan, as amended, requires monthly payments of principal of $33 thousand plus interest at the prime rate plus 3% per annum through the earlier of maturity in January 2025 or the termination, maturity or repayment of the EBGL credit facility. The Star Loan is secured by the assets of SRE, 947 Waterford Road, LLC, 300 Park Street, LLC and 56 Mechanic Falls Road, LLC and guaranteed by the Company. The Star loan is subject to certain financial covenants. The financial covenants under the Star Loan Agreement include maintenance of a Debt Service Coverage Ratio of not less than 1:00 to 1:00, as defined in the Star Loan Agreement. The occurrence of any event of default under the Star Loan Agreement may result in the obligations of the Star Borrowers becoming immediately due and payable. As of June 30, 2022, no event of default was deemed to have occurred and the Star Borrowers were in compliance with the bi-annual financial covenants under the Star Loan Agreement measured as of June 30, 2022. The outstanding balance is classified as a short-term obligation as a result of the acceleration clauses within the EBGL and KBS credit facility and the cross-default provisions. As of June 30, 2022, the short-term loan includes $0.9 million of the Star Loan, net of issuance costs. Paycheck Protection Program From April 2020 through May 2020, the Company and its subsidiaries received $6.7 million of loans under the Paycheck Protection Program (“PPP”). Total PPP loans received by the Healthcare division and Construction division were $5.5 million and $1.2 million, respectively. During the fiscal years ended 2020 and 2021, the Company applied for forgiveness on all PPP loans. As of December 31, 2021, all PPP loans were forgiven, resulting in a gain of $4.2 million in 2021 and $2.5 million in 2020.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the normal course of business, we have been and will likely continue to be subject to other 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 and 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 different 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 upon currently available information and is subject to significant judgment and a variety of assumptions, as well as known and unknown uncertainties.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We provide for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of differences between the tax basis of assets or liabilities and their carrying amounts in the financial statements. We provide a valuation allowance for deferred tax assets if it is more likely than not that these items will expire before we are able to realize their benefit. We calculate the valuation allowance in accordance with the authoritative guidance relating to income taxes, which requires an assessment of both positive and negative evidence regarding the realizability of these deferred tax assets, when measuring the need for a valuation allowance. Significant judgment is required in determining any valuation allowance against deferred tax assets. We continue to record a full valuation allowance against our deferred tax assets and intend to maintain a valuation allowance until sufficient positive evidence exists to support its reversal. Intraperiod tax allocation rules require us to allocate our provision for income taxes between continuing operations and other categories of comprehensive income, such as discontinued operations. For the three months ended June 30, 2022, we recorded an income tax benefit of $327 thousand within continuing operations and zero income tax expense within discontinued operations. For the three months ended June 30, 2021, we recorded an income tax expense of $32 thousand within continuing operations and zero income tax expense within discontinued operations. For the six months ended June 30, 2022, we recorded an income tax expense of $623 thousand within continuing operations and zero income tax expense within discontinued operations. For the six months ended June 30, 2021, we recorded an income tax expense of $34 thousand within continuing operations and an income tax expense of $72 thousand within discontinued operations. The tax expense for the six months ended June 30, 2022 primarily relates to an ownership change under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”) that occurred in January 2022 which required us to establish an additional valuation allowance on net operating losses that the Company cannot utilize in the future. As of June 30, 2022, we had unrecognized tax benefits of approximately $2.6 million related to uncertain tax positions. Included in the unrecognized tax benefits were $2.1 million of tax benefits that, if recognized, would reduce our annual effective tax rate, subject to the valuation allowance.

Equity [Abstract]
Perpetual Preferred Stock	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 10.0% per annum of the liquidation preference of $10.00 per share. Dividends are payable quarterly, in arrears, on 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 six or more consecutive quarters, then the holders of those shares together with holders of all other series of preferred stock equal in rank will be entitled to vote separately as a class for the election of two 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. Under change of control or other conditions, the Series A Preferred Stock may be subject to redemption. The Company may redeem the Series A Preferred Stock upon the occurrence of a change of control, subject to certain conditions. The Company may also voluntarily redeem some or all of the Series A Preferred Stock on or after September 10, 2024. On February 25, 2022 and May 19, 2022, our board of directors declared cash dividends to holders of our Series A Preferred Stock of $0.25 per share, for an aggregate amount of approximately $1.0 million. The record dates for these dividends were March 1, 2022 and June 1, 2022, respectively, and the payment dates were March 10, 2022 and June 10, 2022, respectively. On June 2, 2021, the board of directors adopted a tax benefit preservation plan in the form of a Section 382 Rights Agreement (the “382 Agreement”). The 382 Agreement is intended to diminish the risk that our ability to use our net operating loss carryforwards to reduce future federal income tax obligations may become substantially limited due to an “ownership change,” as defined in Section 382 of the Code. The board of directors authorized and declared a dividend distribution of one right for each outstanding share of common stock, par value $0.0001 per share, to stockholders of record as of the close of business on June 14, 2021. Each right entitles the registered holder to purchase from the one one-thousandth of a share of Series C Participating Preferred Stock, par value $0.0001 per share (the “Series C Preferred Stock”), at an exercise price of $12.00 per one one-thousandth of a share of Series C Preferred Stock, subject to adjustment. The rights will become exercisable following (i) 10 days after a public announcement that a person or group has become an Acquiring Person (as defined in the 382 Agreement); and (ii) 10 business days (or a later date determined by the board of directors) 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. In addition, upon the occurrence of certain events, the exercise price of the rights would be adjusted and holders of the rights (other than rights owned by an acquiring person or group) would be entitled to purchase common stock at approximately half of market value. Given the potential adjustment of the exercise price of the rights, the rights could cause substantial dilution to a person or group that acquires 4.99% or more of common stock on terms not approved by the board of directors. No rights were exercisable at June 30, 2022. There is no impact to financial results as a result of the adoption of the rights plan for the six months ended June 30, 2022.

Equity Transactions	Equity Transactions On January 24, 2022, we closed the 2022 Public Offering pursuant to an underwriting agreement with Maxim Group LLC (“Maxim”), as representative of the underwriters. Company issued and sold (A)(i) 9,175,000 shares of the Company’s Common Stock, (ii) an aggregate of 325,000 pre-funded warrants to purchase up to an aggregate of 325,000 shares of Common Stock, and (iii) an aggregate of 9,500,000 common stock purchase warrants (the “Firm Purchase Warrants”) to purchase up to 9,500,000 shares of Common Stock and (B) at the election of Maxim, (i) up to an additional 1,425,000 shares of Common Stock and/or (ii) up to an additional 1,425,000 shares of common stock purchase warrants (the “Option Purchase Warrants”, and together with the Firm Purchase Warrants, the “Warrants”). Maxim partially exercised its over-allotment option for the purchase of 1,425,000 Warrants for a price of $0.01 per Warrant. Each share of common stock (or pre-funded warrant in lieu thereof) was sold together with one common warrant to purchase one share of common stock at a price of $1.50 per share and common warrant. Gross proceeds, before deducting underwriting discounts and offering expenses and excluding any proceeds we may receive upon exercise of the Warrants, were $14.3 million and net proceeds were $12.7 million. In addition, as part of the 2022 Public Offering, the Company issued to Maxim 237,500 common stock purchase warrants (the “Underwriter’s Warrants”) to purchase up to 237,500 shares of Common Stock at an exercise price of $1.65 per common warrant. The Underwriter’s Warrants have an initial exercise date beginning July 19, 2022, and therefore, no proceeds had been received as of June 30, 2022. As of June 30, 2022, of the warrants issued through the public offering we closed on May 28, 2020 (the “2020 Public Offering”), 1.0 million warrants were exercised and 1.4 million warrants remained outstanding, which represents 0.7 million shares of common stock equivalents, at an exercise price of $2.25. As of June 30, 2022, of the Warrants issued through the 2022 Public Offering, there were 10.9 million Warrants and 0.3 million prefunded warrants outstanding at an exercise price of $1.50 and $0.01, respectively. The Underwriter’s Warrants have not been exercised.

This VIE is a small private company that is primarily involved in research related to new heart imaging technologies. We have determined that the governance structures of this entity do not allow us to direct the activities that would significantly affect its economic performance. Therefore, we are not the primary beneficiary, and the results of operations and financial position of the VIE are not included in our condensed consolidated financial statements. We account for this investment as non-marketable equity securities which is valued at cost less impairment.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements included in this Form 10-Q have been prepared in accordance with the U.S. Securities and Exchange Commission (the “SEC”) instructions for Quarterly Reports on Form 10-Q. Accordingly, the condensed consolidated financial statements are unaudited and do not contain all the information required by U.S. generally Accepted Accounting Principles (“GAAP”) to be included in a full set of financial statements. The unaudited condensed consolidated balance sheet at December 31, 2021 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for a complete set of financial statements. The audited consolidated financial statements for our fiscal year ended December 31, 2021, filed with the SEC on Form 10-K on March 31, 2022, include a summary of our significant accounting policies and should be read in conjunction with this Form 10-Q. In the opinion of management, all material adjustments necessary to present fairly the results of operations, cash flows, and balance sheets for such periods have been included in this Form 10-Q. All such adjustments are of a normal recurring nature. The results of operations for interim periods are not necessarily indicative of the results of operations for the entire year.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and disclosures made in the accompanying notes to the condensed consolidated financial statements. Significant estimates and judgments include those related to revenue recognition, goodwill valuation, and income taxes. Actual results could materially differ from those estimates.
Revenue Recognition	Revenue Recognition We recognize revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606 and Topic 842. Pursuant to ASC 606, Revenue from Contracts with Customers , we recognize revenue when a customer obtains control of promised goods or services. We record the amount of revenue that reflects the consideration that it expects to receive in exchange for those goods or services. We apply the following five-step model in order to determine this amount: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company has elected to use the practical expedient under ASC 606 to exclude disclosures of unsatisfied remaining performance obligations for (i) contracts having an original expected length of one year or less or (ii) contracts for which the practical expedient has been applied to recognize revenue at the amount for which it has a right to invoice. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue. The majority of our contracts have a single performance obligation, as we provide a series of distinct goods or services that are substantially the same and are transferred with the same pattern to the customer. For contracts with multiple performance obligations, we allocate the total transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. We use an observable price to determine the stand-alone selling price for separate performance obligations or a cost plus margin approach when one is not available. 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 recognition is evaluated on a contract by contract basis. Performance obligations are satisfied over time as work progresses or at a point in time. A performance obligation is satisfied over time if we have an enforceable right to payment. Determining if there is an enforceable right to payment is assessed on a contract by contract basis. For contracts requiring over time revenue recognition, the selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We use a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress towards completion is measured based on the costs incurred to date. Our products are generally not sold with a right of return and the Company does not provide significant credits or incentives, which may be variable consideration when estimating the amount of revenue to be recognized. Healthcare Services Revenue Recognition. We generate service revenue primarily from providing diagnostic services to our customers. Service revenue within our Healthcare reportable segment is derived from providing our customers with contract diagnostic services, which includes use of our imaging systems, qualified personnel, radiopharmaceuticals, licensing, logistics and related items required to perform testing in their own offices. We bill customers either on a per-scan or fixed-payment methodology, depending upon the contract that is negotiated with the customer. Within our Healthcare segment, we also rent cameras to healthcare customers for use in their operations. Rental revenues are structured as either a weekly or monthly payment arrangement, and are recognized in the month rental assets are provided. Revenue related to provision of our services is recognized at the time services are performed. Healthcare Product and Product-Related Revenue Recognition. We generate revenue from product and product-related sales, primarily from the sale of gamma cameras, accessories, and radiopharmaceuticals doses. Healthcare product revenues are generated from the sale of internally developed solid-state gamma camera imaging systems and post-warranty camera maintenance service contracts. Revenue from sales of imaging systems is generally recognized at point in time upon delivery of systems and acceptance by customers. We also provide installation services and training on cameras sold, primarily in the United States. Installation and initial training is generally performed shortly after delivery and the revenue related to the provision of these services is recognized at the time services are performed. Neither installation nor training is essential to the functionality of the product. Finally, we offer camera maintenance service contracts that are sold beyond the term of the initial warranty, generally one year from the date of purchase. Revenue from these service contracts is deferred and recognized ratably over the period of the obligation. We offer time and material services and record revenue when service is performed. Radiopharmaceuticals doses revenue, generated by Healthcare, is generally recognized when delivered to the customer. Construction Revenue Recognition. Our Construction division is made up of three operating businesses, KBS Builders, Inc. (“KBS”), EdgeBuilder, Inc. (“EdgeBuilder”), and Glenbrook Building Supply, Inc. (“Glenbrook”)—with the latter two managed together and referred to jointly as “EBGL”. KBS, EdgeBuilder and Glenbrook are wholly owned subsidiaries of Star Equity and are referred to collectively herein, and together with ATRM Holdings, Inc. (“ATRM”), as the “Construction Subsidiaries.” Within the Construction division, we service residential and commercial construction projects by manufacturing modular housing units and other products and supply general contractors with building materials. 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. 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 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 classified in deferred revenue in the condensed Consolidated Balance Sheets. Contract liabilities are reduced when the associated revenue from the contract is recognized, which is generally within one year. Contract Assets. 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 costs to obtain a contract when the amortization period would have been one year or less. These costs mainly include the internal sales commissions; under the terms of these programs these are generally earned and the costs are recognized at the time the revenue is recognized. Deferred Revenue
Lessee Accounting	Lessee Accounting We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities, and operating lease liabilities, net of current portion in our condensed consolidated balance sheets. Finance leases are included in property and equipment, finance lease liabilities, net of current portion, and finance lease liabilities in our condensed Consolidated Balance Sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use the implicit discount rate when readily determinable; however, as most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The ROU asset also includes any lease payments made and excludes lease incentives. Our lease valuation may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. We elected not to separate lease and non-lease components of our leases in which we are the lessee and lessor. Additionally, we elected not to recognize right-of-use assets and leases liabilities that arise from short-term leases of twelve months or less.
Lessor Accounting	Lessor Accounting The majority of the lease income of the Healthcare division comes from camera rentals and the lease income of the Construction division comes from the rental of the Waterford facility to a commercial tenant. We determine lease classification at the commencement date. Leases not classified as sales-type or direct financing leases are classified as operating leases. The primary accounting criteria we use for lease classification are (a) review to determine if the lease transfers ownership of the underlying asset to the lessee by the end of the lease term, (b) review to determine if the lease grants the lessee a purchase option that the lessee is reasonably certain to exercise, (c) determine, using a seventy-five percent or more threshold, if the lease term is for a major part of the remaining economic life of the underlying asset (however, we do not use this classification criterion when the lease commencement date falls within the last 25 percent of the total economic life of the underlying asset) and (d) determine, using a 90 percent or more threshold, if the present value of the sum of the lease payments and any residual value guarantees equal or exceeds substantially all of the fair value of the underlying asset. We do not lease equipment of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. Each of our leases is classified as an operating lease. We elected the operating lease practical expedient for its leases to not separate non-lease components of regular maintenance services from associated lease components. This practical expedient is available when both of the following are met: (i) the timing and pattern of transfer of the non-lease components and associated lease component are the same and (ii) the lease component, if accounted for separately, would be classified as an operating lease. Property taxes paid by the lessor that are reimbursed by the lessee are considered to be lessor costs of owning the asset, and are recorded gross with revenue included in other non-interest income and expense recorded in operating expenses. We selected a lessor accounting policy election to exclude from revenue and expenses sales taxes and other similar taxes assessed by a governmental authority on lease revenue-producing transactions and collected by the lessor from a lessee. Operating lease equipment is carried at cost less accumulated depreciation. Operating lease equipment is depreciated to its estimated residual value using the straight-line method over the lease term or estimated useful life of the asset. Rental revenue on operating leases is recognized on a straight-line basis over the lease term unless collectability is not probable. In these cases, rental revenue is recognized as payments are received.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable. We limit our exposure to credit loss by generally placing cash in high credit quality financial institutions. Cash balances are maintained primarily at major financial institutions in the United States and a portion of which exceed the regulatory limit of $250,000 insured by the Federal Deposit Insurance Corporation (FDIC). We have not experienced any credit losses associated with our cash balances. Additionally, we have established guidelines regarding diversification of our investments and their maturities, which are designed to maintain principal and maximize liquidity.
Variable Interest Entities	Variable Interest Entities We determine at the inception of each arrangement whether an entity in which we have made an investment or in which we have other variable interests is considered a variable interest entity (“VIE”). We consolidate VIEs when we are the primary beneficiary. We are the primary beneficiary of a VIE when we have the power to direct activities that most significantly affect the economic performance of the VIE and have the obligation to absorb the significant losses or benefits. If we are not the primary beneficiary in a VIE, we account for the investment or other variable interests in a VIE in accordance with applicable GAAP. Periodically, we assess whether any changes in our interest or relationship with the entity affect our determination of whether the entity is a VIE and, if so, whether we are the primary beneficiary.
Reclassification	Reclassification PPP Loan forgiveness reclassification has been made to the prior period financial statements to conform to the current year financial statement presentation of the condensed Consolidated Statements of Operations. This change did not impact previously reported net loss, loss per share, stockholders’ equity, total assets or the condensed Consolidated Statements of Cash Flows. Finance Lease liabilities and Investments reclassifications have been made to the prior period financial statements to conform to the current year financial statement presentation of the condensed Consolidated Balance Sheets. These changes did not impact previously reported net (loss) income, (loss) income per share, stockholders’ equity, total liabilities, total assets or the condensed Consolidated Statements of Cash Flows.
New Accounting Standards To Be Adopted and Recently Adopted Accounting Standards	New Accounting Standards To Be Adopted No new accounting standards were issued in the quarter ended June 30, 2022 that are expected to have a material impact on our financial statements. Recently Adopted Accounting Standards No accounting standards were adopted in the quarter ended June 30, 2022 that are expected to have a material impact on our financial statements.
Commitments and Contingencies	In the normal course of business, we have been and will likely continue to be subject to other 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 and 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 different 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 upon currently available information and is subject to significant judgment and a variety of assumptions, as well as known and unknown uncertainties.
