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, 2022 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, 2022, filed with the SEC on Form 10-K on March 15, 2023, 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 related to continuing operations are of a normal recurring nature. The results of operations for interim periods are not necessarily indicative of the results of continuing operations for the entire year. The Company Star Equity Holdings, Inc. (“Star Equity,” the “Company,” “we,” or “our”) is a multi-industry diversified holding company with two divisions: Construction and Investments. We previously had a Healthcare division which was sold on May 4, 2023, as further described in Note 2. “Discontinued Operations”. Our common stock and preferred stock are listed on the NASDAQ Global Market exchange as “STRR” and “STRRP”, respectively. Liquidity and Management’s Plan At December 31, 2022, we identified certain conditions and events which in the aggregate required management to perform an assessment of the Company’s ability to continue as a going concern for one year from the financial statements issuance date. Management’s analysis indicated that there was no substantial doubt regarding the entity’s ability to continue as a going concern for one year from the financial statements issuance date. For the six months ended June 30, 2023 we achieved net income of $26.0 million and positive cash flow from operations of $1.9 million. As of June 30, 2023, cash and cash equivalents amounted to $21.4 million and the value of our investments in publicly traded companies was $4.8 million. Additionally, we received approximately $19.7 million in cash from the sale of our Healthcare business on May 4, 2023. We also gave notice to eCapital (as defined in “Debt”) that we would not be renewing our credit facilities with them upon the June 30, 2023 renewal date and paid the full outstanding balance due under all arrangements with eCapital. We believe our June 30, 2023 cash balance provides us ample liquidity to fund our operations for twelve months from the issuance date of these financial statements. Our forecasts are dependent on our ability to maintain margins at our operating companies which includes achieving levels of booked orders, minimizing expenses and achieving certain free cash flow benchmarks. We have begun to explore certain financing arrangements, including real estate sale and leaseback opportunities. There can be no assurance that we will enter into such a financing arrangement or as to the terms of any such financing arrangement. 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 inventory, revenue recognition, lease accounting, fair value measurements (including contingent considerations), litigation and contingent liabilities, variable interest entities, intangible assets and goodwill valuations, equity classification and transactions, and income taxes. Actual results could materially differ from those estimates. 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 or in major money market mutual funds offered through brokerage firms. A portion of our cash balances are maintained at major banking institutions in the United States, a portion of which may from time to time 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. As of June 30, 2023, we have $1.2 million of cash in excess of FDIC insured limits. New Accounting Standards To Be Adopted No new accounting standards were issued in the quarter ended June 30, 2023 that are expected to have a material impact on our financial statements.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On May 4, 2023, we entered into a Stock Purchase and Contribution Agreement (the “Purchase Agreement”), by and among the Company, Digirad Health Inc., a Delaware corporation and wholly owned subsidiary of the Company (“Digirad Health”), TTG Imaging Solutions, LLC, a Pennsylvania limited liability company (the “Buyer”), and the Buyer’s parent, Insignia TTG Parent LLC, a Delaware limited liability company (the “Parent”). Pursuant to the Purchase Agreement, (i) the Buyer purchased 85% of the issued and outstanding shares of Digirad Health, on the terms and subject to the conditions set forth therein and (ii) the Company contributed to Parent 15% of the issued and outstanding shares of stock of Digirad Health (the “Contributed Shares”) in exchange for New Units (as defined in the Purchase Agreement) of Parent (the “Transaction”). The total aggregate consideration payable to the Company for the Transaction was $40 million, comprised of $19.7 million ($27 million less paydowns of debt to Webster Bank (see Note 8. “Debt”) and transaction costs) in cash, a $7 million promissory note (see Note 5. “Supplemental Balance Sheet Information”), and $6 million of New Units in the Parent (see Note 7. “Fair Value Measurements”). The Company completed the sale of Digirad Health simultaneously with entering into the Purchase Agreement. We deemed the disposition of Digirad Health, which operated our Healthcare business unit, to represent a strategic shift that will have a major effect on our operations and financial results. As of the date of these financial statements, the results of operations of the Healthcare business unit represent “discontinued operations” in accordance with GAAP (ASC 205-20-45-1B). As such, the assets and liabilities, as well as the earnings, of the discontinued operation are presented separately in the unaudited condensed consolidated financial statements for all periods presented. Unless otherwise noted, discussion within the notes to the unaudited condensed consolidated financial statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations relates to continuing operations. Our variable interest entity (“VIE”), for which we are not the primary beneficiary, was disposed of as part of the sale of our Healthcare division. This VIE was in a small private company that is primarily involved in research related to new heart imaging technologies. The following table presents financial results of our Healthcare division for the three and six months ended June 30, 2023 and 2022 (in thousands). Note that we owned this division through May 4, 2023 and that both the three months ended June 30, 2023 and the six months ended June 30, 2023 results reflect that period only: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Total revenues $ 4,603 $ 13,912 $ 17,962 $ 27,330 Total cost of revenues 2,376 10,234 12,408 20,476 Gross profit 2,227 3,678 5,554 6,854 Operating expenses: Selling, general and administrative 622 3,674 3,370 6,880 Amortization of intangible assets — — — — (Gain) loss on disposal of discontinued operations (26,680) — (26,680) — Total operating expenses (26,058) 3,674 (23,310) 6,880 Income (loss) from discontinued operations 28,285 4 28,864 (26) Other (expense) income, net (1,023) (23) (1,015) 81 Interest expense, net (5) (84) (173) (148) Income (loss) from discontinued operations before income taxes 27,257 (103) 27,676 (93) Income tax benefit (provision) (300) (183) (300) 537 Income (loss) from discontinued operations $ 26,957 $ (286) $ 27,376 $ 444 The carrying amounts of the major classes of assets reported as “Assets - discontinued operations” consist of the following as of December 31, 2022 (in thousands): December 31, 2022 Cash and cash equivalents $ 288 Accounts receivable, net 9,782 Inventories, net 5,949 Other current assets 1,832 Property and equipment, net 2,683 Operating lease right-of-use assets, net 2,626 Goodwill 1,608 Other assets 521 $ 25,289 The carrying amounts of the major classes of liabilities reported as “Liabilities - discontinued operations” consist of the following as of December 31, 2022 (in thousands): December 31, 2022 Accounts payable $ 1,983 Other accrued liabilities 1,863 Accrued compensation 253 Accrued liabilities 2,675 Deferred revenue 1,703 Operating lease liabilities 1,056 Finance lease liabilities, current portion 314 Short-term debt and current portion of long-term debt 8,299 Deferred tax liabilities 176 Operating lease liabilities, net of current portion 1,631 Finance lease liabilities, net of current portion 291 Other liabilities 298 $ 20,542 The following table presents the significant non-cash operating, investing and financing activities from discontinued operations for the six months ended June 30, 2023 and 2022 (in thousands): Six Months Ended June 30, 2023 2022 Operating activities Net income (loss) from discontinued operations $ 27,376 $ 444 Depreciation 332 638 Amortization of intangible assets — 1 Non-cash lease expense — 392 Write-off of borrowing costs 16 20 (Gain) loss on disposal of discontinued operations (26,680) — Share-based compensation 1 4 (Gain )Loss on disposal of assets 135 (67) Provision for bad debt 48 (47) Deferred income taxes (176) (597) Accounts receivable 1,304 (4) Inventory (681) (1,180) Other assets 786 (3,101) Accounts payable 994 1,572 Accrued compensation (580) (208) Deferred revenue (101) 26 Operating lease liabilities (10) (386) Other liabilities (1,825) 1,615 Net cash provided by (used in) operating activities 939 (878) Net cash provided by (used in) investing activities — (404) Net cash provided by (used in) financing activities 442 815 Net increase (decrease) in cash and cash equivalents and restricted cash $ 1,381 $ (467) Following is the reconciliation of purchase price to the gain recognized in income from discontinued operations for the six months ended June 30, 2023 (in thousands), prior to any proposed working capital adjustments: Estimated proceeds of the disposition, net of transaction costs and indebtedness payoff $ 32,682 Assets of the businesses (24,071) Liabilities of the businesses 18,069 Pre-tax gain on the disposition $ 26,680

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 income (loss) attributable to common stockholders to warrants because the holders of our warrants are not contractually obligated to share in our income (loss). Basic net income (loss) per share attributable to common stockholders is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (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 loss, diluted loss per common share is equal to basic loss 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 income (loss) per share for the periods indicated (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Numerator: Income (loss) from continuing operations, net of tax $ (1,366) $ (1,290) $ (1,350) $ (5,721) Income (loss) from discontinued operations, net of tax (Note 10) 26,957 (286) 27,376 444 Net income (loss) 25,591 (1,576) 26,026 (5,277) Deemed dividend on Series A perpetual preferred stock (479) (479) (958) (958) Net income (loss) attributable to common shareholders $ 25,112 $ (2,055) $ 25,068 $ (6,235) Denominator: Weighted average common shares outstanding 15,195 15,054 15,193 13,751 Weighted average prefunded warrants outstanding 325 325 325 280 Weighted average shares outstanding - basic 15,520 15,379 15,518 14,031 Dilutive potential common shares: Restricted stock units 226 57 188 69 Weighted average shares outstanding - diluted 15,746 15,436 15,706 14,100 Net income (loss) per share Continuing operations Basic $ (0.09) $ (0.08) $ (0.09) $ (0.41) Diluted $ (0.09) $ (0.08) $ (0.09) $ (0.41) Discontinued operations Basic $ 1.74 $ (0.02) $ 1.76 $ 0.03 Diluted $ 1.71 $ (0.02) $ 1.74 $ 0.03 Net income (loss) per share Basic $ 1.65 $ (0.10) $ 1.68 $ (0.38) Diluted $ 1.63 $ (0.10) $ 1.66 $ (0.37) Net income (loss) per share, attributable to common shareholders Basic $ 1.62 $ (0.13) $ 1.62 $ (0.44) Diluted $ 1.59 $ (0.13) $ 1.60 $ (0.44) *Earnings per share may not add due to rounding Antidilutive common stock equivalents are excluded from the computation of diluted income (loss) per share.

Warranty Reserves Within our Construction division, KBS Builders, Inc. (“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. EdgeBuilder, Inc. (“EdgeBuilder”) 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. Estimated warranty costs are accrued in the period that the related revenue is recognized. Note Receivable As a part of the Transaction described further in Note 2. “Discontinued Operations”, a $7 million promissory note was entered into which represents an unsecured note receivable on our balance sheet. The note has a maturity date of May 3, 2029 with payment-in-kind (non-cash) interest on the outstanding principal balance hereof to accrue at the Interest Rate. The Interest Rate is defined as (i) during the period from the date of issuance of the note through the third anniversary of the date of issuance of the note, a per annum rate equal to the sum of (x) 5.0% per annum plus (y) the greater of 5.0% per annum and the weighted average term SOFR-based interest rate of outstanding loans under the Senior Loan Agreement (as defined in the Purchase Agreement) during such period, and (ii) during the period following the third anniversary of the date of issuance of the note, a per annum rate equal to the sum of (x) 5.0% per annum plus (y) the greater of 7.0% per annum and the weighted average term SOFR-based interest rate of outstanding loans under the Senior Loan Agreement during such period. Investment in Private Company As a part of the sale of Digirad Health, the Company received $6.0 million in the common equity of the Parent. The company has elected the measurement alternative under ASC 321. 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. In other words, such securities are adjusted to fair value when an observable price change occurs or impairment is identified.

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 are 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, 2023 and December 31, 2022 (in thousands): Fair Value as of June 30, 2023 Level 1 Level 2 Level 3 Total Assets (Liabilities): Equity securities $ 4,783 $ — $ — $ 4,783 Lumber derivative contracts 43 — — 43 Total $ 4,826 $ — $ — $ 4,826 Fair Value as of December 31, 2022 Level 1 Level 2 Level 3 Total Assets (Liabilities): Equity securities $ 3,490 $ — $ — $ 3,490 Lumber derivative contracts (104) — — (104) Total $ 3,386 $ — $ — $ 3,386 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, 2023 and December 31, 2022, respectively, and recorded in Investments in the condensed Consolidated Balance Sheets. During the six months ended June 30, 2023 and 2022, we recorded an unrealized gain of $947 thousand and $235 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 lumber price volatility, recorded within current assets or liabilities in the condensed Consolidated Balance Sheets. For the six months ended June 30, 2023 and 2022, we recorded a net gain of $4 thousand and net loss of $1.1 million, respectively, in the cost of goods sold in the condensed Consolidated Statements of Operations. As of June 30, 2023, we had a net long (buying) position of 11,110,000 board feet under 101 lumber derivatives contracts. As of December 31, 2022, we had a net long (buying) position of 550,000 board feet under 5 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 for the six months ended June 30, 2023 and 2022, respectively: June 30, 2023 June 30, 2022 Unrealized gain (loss) on lumber derivatives $ 147 $ (1,145) Realized gain (loss) on lumber derivatives (143) 17 Total gain (loss) on lumber derivatives $ 4 $ (1,128)

On February 1, 2022, Sterling became part of Webster Bank, N.A. (“Webster”), and Webster became the successor in interest to the Webster Loan Agreement. In connection with the sale of our Healthcare business on May 4, 2023, the credit facility pursuant to the Webster Loan Agreement was paid in full and terminated. eCapital Credit Facilities EBGL EdgeBuilder and Glenbrook Building Supply, Inc. (“Glenbrook” and, together with EdgeBuilder, collectively the “EBGL Borrowers”) were parties to a Loan and Security Agreement (the “EBGL Loan Agreement”) providing the EBGL Borrowers with a credit facility with eCapital Asset Based Lending Corp. formerly known as Gerber Finance, Inc. (“eCapital”) for borrowings up to $4.0 million, subject to certain borrowing base limitations (the “EBGL Loan”). KBS KBS was a party to a revolving credit facility with eCapital (“KBS Loan Agreement”). The facility, as amended, provided for borrowings up to $4.0 million, subject to certain borrowing base limitations (the “KBS Loan”). The EBGL Loan Agreement and the KBS Loan Agreement contained cross-default provisions and subjective acceleration clauses which could, 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 were also subject to a guaranty by the Company and the Company was responsible for certain facility and other fees. Borrowings under the EBGL Loan Agreement and the KBS Loan Agreement were classified as short-term obligations as the agreements contained subjective acceleration clauses and required a lockbox arrangement whereby all receipts within the lockbox were swept daily to reduce borrowings outstanding. eCapital Term Loan We and certain of our Investments subsidiaries (collectively, the “Star Borrowers”) were party to a Loan and Security Agreement with eCapital, as successor in interest to Gerber Finance, Inc. (as amended, the “Star Loan Agreement”), which provided 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 31, 2025, unless terminated in accordance with the terms therein (the “Star Loan”). During the second quarter of 2023, we notified eCapital that we would not be renewing any of our outstanding eCapital credit facilities upon expiry at June 30, 2023. Subsequently, we paid in full all amounts then outstanding under the Star Loan on May 9, 2023 and closed all credit facilities with eCapital, including the EBGL Loan and the KBS Loan.

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 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.

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, 2023, we recorded an income tax expense of $61 thousand within continuing operations and an expense of $300 thousand within discontinued operations. For the three months ended June 30, 2022, we recorded a $510 thousand income tax expense within continuing operations and an income tax expense of $183 thousand within discontinued operations. For the six months ended June 30, 2023 , we recorded an income tax expense of $61 thousand within continuing operations and a expense of $300 thousand income tax expense within discontinued operations. For the six months ended June 30, 2022, we recorded an income tax expense of $1.2 million within continuing operations and an income tax benefit of $537 thousand within discontinued operations. The tax expense for the six months ended June 30, 2023 primarily relates to a January 2022 ownership change under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), 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, 2023, we had unrecognized tax benefits of approximately $2.0 million related to uncertain tax positions. Included in the unrecognized tax benefits were $2.0 million of tax benefits that, if recognized, would reduce our annual effective tax rate, subject to the valuation allowance.

Segment Reporting [Abstract]
Segments	Segments 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 (our Chief Operating Decision Maker / “CODM”) to evaluate segment performance, the availability of separate financial information, and overall materiality considerations. Effective as of the consummation of the sale of our Healthcare business on May 4, 2023, our business divisions are organized into the following two reportable segments, reflecting the manner in which our CODM assesses performance and allocates resources: 1. Construction 2. Investments Prior to the sale of Digirad Health on May 4 2023, we also had a Healthcare segment.

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, 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 six 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 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. 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 each of February 17, 2023 and May 19, 2023, our board of directors declared a cash dividend to holders of our Series A Preferred Stock of $0.25 per share, for an aggregate amount of approximately $0.5 million. The record dates for these dividend payments were March 1, 2023 and June 1, 2023, respectively, and the payment dates were March 10, 2023 and June 12, 2023, respectively. As of June 30, 2023, we are current on our preferred dividends. 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 to stockholders of record as of the close of business on June 14, 2021. Each right entitles the registered holder to purchase from the Company 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, 2023. There is no impact to financial results as a result of the adoption of the 382 Agreement for the six months ended June 30, 2023.

Through the 2022 Public Offering, we 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. As of June 30, 2023, 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, 2023, 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.

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, 2022 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, 2022, filed with the SEC on Form 10-K on March 15, 2023, 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 related to continuing operations are of a normal recurring nature. The results of operations for interim periods are not necessarily indicative of the results of continuing 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 inventory, revenue recognition, lease accounting, fair value measurements (including contingent considerations), litigation and contingent liabilities, variable interest entities, intangible assets and goodwill valuations, equity classification and transactions, and income taxes. Actual results could materially differ from those estimates.
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 or in major money market mutual funds offered through brokerage firms. A portion of our cash balances are maintained at major banking institutions in the United States, a portion of which may from time to time 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. As of June 30, 2023, we have $1.2 million of cash in excess of FDIC insured limits.
New Accounting Standards To Be Adopted	New Accounting Standards To Be Adopted No new accounting standards were issued in the quarter ended June 30, 2023 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 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 upon currently available information and is subject to significant judgment and a variety of assumptions, as well as known and unknown uncertainties.
