Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Other than policies noted below, there have been no significant changes to the significant accounting policies disclosed in Note 2, Summary of Significant Accounting Policies, of the annual audited financial statements included in the Annual Report. Accounting Estimates The preparation of condensed financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed financial statements and accompanying notes to the condensed financial statements. The accounting estimates that require management’s most significant, difficult and subjective judgments include, but are not limited to, revenue recognition and allowance for expected credit losses, the valuation of notes receivable and inventory, the assessment of recoverability of intangible assets and their estimated useful lives, the valuation and recognition of stock-based compensation, operating lease right-of-use assets and liabilities, the recognition and measurement of current and deferred income tax assets and liabilities, and the valuation of warrant liabilities. Management evaluates its estimates on an ongoing basis as there are changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from these estimates. As of the date of issuance of these unaudited condensed interim financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update estimates, judgments or revise the carrying value of any assets or liabilities. Derivative Financial Instruments The Company evaluates financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, Derivatives and Hedging (“ASC 815”). For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the condensed statements of operations. Warrants issued by the Company that do not meet the criteria for equity treatment are recorded as liabilities. We do not use financial instruments or derivatives for any trading purposes. Fair Value Measurement The fair value of the Company’s financial instruments are estimates of the amounts that would be received if the Company were to sell an asset or the Company paid to transfer a liability in an orderly transaction between market participants at the measurement date or exit price. The assets and liabilities are categorized and disclosed in one of the following three categories: • Level 1—based on quoted market prices in active markets for identical assets and liabilities. • Level 2—based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3—based on unobservable inputs using management’s best estimate and assumptions when inputs are unavailable. Fair value measurements are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. Related Parties The Company follows ASC 850, Related Party Disclosures, for the identification of related parties and disclosure of related party transactions. In May 2023, the Company completed the Private Placement (as defined in Note 11, Redeemable Convertible Preferred Stock) with NR-GRI Partners, LP (“NR-GRI”), an affiliate of North Run Capital, LP (“North Run”). Pursuant to the terms of the Private Placement, Thomas B. Ellis and Todd B. Hammer, co-managing partners of North Run, joined the Company’s Board of Directors following the Company’s 2023 Annual Meeting of Stockholders. Refer to Note 9, Warrant Liabilities, and Note 11, Redeemable Convertible Preferred Stock, for more details related to the Private Placement. In June 2023, the Company entered into an international distribution agreement in India with a company owned by an employee at that time. As of April 1, 2024, the owner is no longer an employee of the Company. The Company established the distributor relationship to gain regulatory and operational efficiencies, as well as to establish consistent operations with all other international markets where it conducts business. During the year ended December 31, 2023, the Company began transitioning transactions with customers in India to the distributor. The Company recognized $290 in product revenue, $301 in cost of product sales, and $119 in selling, general and administrative expenses for the three months ended March 31, 2024 associated with its Indian operations. There were no amounts due from, or due to, the distributor at March 31, 2024. Income Taxes Income tax expense/(benefit) from continuing operations for the three months ended March 31, 2024 and 2023 was $0 in each period, which resulted primarily from maintaining a full valuation allowance against the Company’s net deferred tax assets. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), certain substantial changes in the Company’s ownership may result in a limitation on the amount of net operating loss and tax credit carryforwards that may be used in future years. During the second quarter of 2023, the Company experienced a change in control event resulting from the Private Placement of Series A Redeemable Convertible Preferred Stock, triggering the application of Section 382 of the Code. Refer to Note 11, Redeemable Convertible Preferred Stock, for more details related to the Private Placement. The Company has not completed an analysis to determine whether any additional limitations have been triggered under Sections 382 and 383 of the Code as of March 31, 2024. The Company computed and applied limitations of tax deductions in the income tax provision computation for the year ended December 31, 2023; however, these limitations do not have a material impact on the financial statements. Due to the existence of the valuation allowance, future changes in the Company’s deferred taxes will not impact its effective tax rate or balance sheet. Recently Issued Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires enhanced disclosures about segment expenses on an annual and interim basis. This standard is effective for the Company’s annual financial statements for the year ending December 31, 2024 and for interim periods beginning in 2025. The Company is currently evaluating the impact of this standard on the financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures, which requires (1) disclosure of specific categories in the rate reconciliation and (2) additional information for reconciling items that meet a quantitative threshold. Additionally, the amendment requires disclosure of certain disaggregated information about income taxes paid, income from continuing operations before income tax expense (benefit) and income tax expense (benefit). The standard is effective for the Company’s annual financial statements for the year ending December 31, 2025. The Company is currently evaluating the impact of this standard on the financial statements.

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Other than policies noted below, there have been no significant changes to the significant accounting policies disclosed in Note 2, Summary of Significant Accounting Policies, of the annual audited financial statements included in the Annual Report.

Accounting Estimates

The preparation of condensed financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed financial statements and accompanying notes to the condensed financial statements. The accounting estimates that require management’s most significant, difficult and subjective judgments include, but are not limited to, revenue recognition and allowance for expected credit losses, the valuation of notes receivable and inventory, the assessment of recoverability of intangible assets and their estimated useful lives, the valuation and recognition of stock-based compensation, operating lease right-of-use assets and liabilities, the recognition and measurement of current and deferred income tax assets and liabilities, and the valuation of warrant liabilities. Management evaluates its estimates on an ongoing basis as there are changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from these estimates.

As of the date of issuance of these unaudited condensed interim financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update estimates, judgments or revise the carrying value of any assets or liabilities.

Derivative Financial Instruments

The Company evaluates financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, Derivatives and Hedging (“ASC 815”). For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the condensed statements of operations. Warrants issued by the Company that do not meet the criteria for equity treatment are recorded as liabilities. We do not use financial instruments or derivatives for any trading purposes.

Fair Value Measurement

The fair value of the Company’s financial instruments are estimates of the amounts that would be received if the Company were to sell an asset or the Company paid to transfer a liability in an orderly transaction between market participants at the measurement date or exit price. The assets and liabilities are categorized and disclosed in one of the following three categories:

•

Level 1—based on quoted market prices in active markets for identical assets and liabilities.

•

Level 2—based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•

Level 3—based on unobservable inputs using management’s best estimate and assumptions when inputs are unavailable.

Fair value measurements are classified in their entirety based on the lowest level of input that is significant to their fair value measurement.

Related Parties

The Company follows ASC 850, Related Party Disclosures, for the identification of related parties and disclosure of related party transactions.

In May 2023, the Company completed the Private Placement (as defined in Note 11, Redeemable Convertible Preferred Stock) with NR-GRI Partners, LP (“NR-GRI”), an affiliate of North Run Capital, LP (“North Run”).

Income Taxes

Income tax expense/(benefit) from continuing operations for the three months ended March 31, 2024 and 2023 was $0 in each period, which resulted primarily from maintaining a full valuation allowance against the Company’s net deferred tax assets.

Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), certain substantial changes in the Company’s ownership may result in a limitation on the amount of net operating loss and tax credit carryforwards that may be used in future years.
