Net Loss Per Share

3 Months Ended

Mar. 31, 2025

Earnings Per Share [Abstract]

Net Loss Per Share

Basic net loss per share of common stock is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during each period, without consideration for potential dilutive shares of common stock. Diluted net loss per share of common stock is computed by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method and if-converted method, as applicable. In periods in which the Company reports a net loss, diluted net loss per share will be the same as basic net loss per share since dilutive shares are not assumed to have been issued if their effect is antidilutive. As a result, for the periods in which the Company experienced a net loss, the weighted-average shares used to calculate both basic and diluted net loss per share are the same.

The following table sets forth the computation of basic and diluted net loss per share to common stockholders:


	Three Months Ended March 31,
(in thousands, except share and per share data)	2025			2024
Numerator:
Net loss	$	(7,001	)	$	(11,506	)

Net loss per share of common stock – basic	$	(0.11	)	$	(0.19	)
Net loss per share of common stock – diluted	$	(0.11	)	$	(0.19	)

The Company excluded the effect of the below elements from our calculation of diluted loss per share, as their inclusion would have been anti-dilutive. These amounts represent the number of instruments outstanding at the end of the period.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Nature of Operations

Tigo Energy, Inc. (f/k/a Roth CH Acquisition IV Co.) and subsidiaries (together, the “Company”) consists of Tigo Energy, Inc. (“Tigo”), its wholly-owned direct and indirect subsidiaries: Tigo Energy MergeCo, Inc. (f/k/a Tigo Energy, Inc.) (“Legacy Tigo”), Tigo Energy Brasil Ltda., Tigo Energy Philippines Inc., Tigo Energy Israel Ltd., Tigo Energy AI Ltd. (f/k/a Foresight Energy, Ltd. (“fSight”)), Tigo Energy Italy SRL, Tigo Energy Equipment Trading (Suzhou) Co., Ltd. and Tigo Energy Australia Pty Ltd. Prior to the consummation of the Business Combination (as defined below), the operations of the Company were conducted through Legacy Tigo. Legacy Tigo was incorporated in Delaware in 2007 and commenced operations in 2010.

The Company provides solar and energy storage solutions, including module level power electronics (“MLPE”) designed to maximize the energy output of individual solar modules, delivering more energy, active management, and enhanced safety for utility, commercial, and residential solar arrays. By combining its MLPE and solar optimizer technology with intelligent, cloud-based software capabilities, the Company enables advanced energy monitoring, system diagnostics, and real-time control. These smart hardware and software solutions enhance system performance, lower operating costs, and ensure compliance with safety regulations, including rapid shutdown requirements. In addition to MLPE, the Company develops and manufactures inverters and battery storage systems for the residential solar-plus storage market, further expanding its suite of solutions for efficient and reliable energy management. The Company is headquartered in Campbell, California, with offices in Europe, Asia, and the Middle East.

Entry into a Material Definitive Agreement

On December 5, 2022, Roth CH Acquisition IV Co., a Delaware corporation (“ROCG”), Roth IV Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of ROCG (“Merger Sub”), and Legacy Tigo, entered into an Agreement and Plan of Merger, as amended on April 6, 2023 (the “Merger Agreement”), pursuant to which, among other transactions, on May 23, 2023 (the “Closing Date”), Merger Sub merged with and into Legacy Tigo (the “Merger”), with Legacy Tigo surviving the Merger as a wholly-owned subsidiary of ROCG (the Merger, together with the other transactions described in the Merger Agreement, the “Business Combination”). In connection with the closing of the Business Combination, ROCG changed its name to “Tigo Energy, Inc.”

Pursuant to the Business Combination, the merger between ROCG and Legacy Tigo was accounted for as a reverse recapitalization in accordance with U.S. GAAP (the “Reverse Recapitalization”). Under this method of accounting, ROCG was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Reverse Recapitalization was treated as the equivalent of Legacy Tigo issuing stock for the net assets of ROCG, accompanied by a recapitalization. The financial statements of the Company represent a continuation of the financial statements of Legacy Tigo with the Business Combination being treated as the equivalent of Legacy Tigo issuing stock for the net assets of ROCG, accompanied by a recapitalization.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) promulgated by the Financial Accounting Standards Board (“FASB”). The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

The Company has determined the functional currency of the subsidiaries to be the U.S. dollar. The Company remeasures monetary assets and liabilities of its foreign operations at exchange rates in effect at the balance sheet date and nonmonetary assets and liabilities at their historical exchange rates. Expenses are remeasured at the weighted-average exchange rates during the relevant reporting period. These remeasurement gains and losses are recorded in other income, net in the condensed consolidated statements of operations and comprehensive loss and were not material for the three months ended March 31, 2025, and 2024.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments (which consist primarily of accruals, estimates and assumptions that impact the unaudited condensed consolidated financial statements) considered necessary to present fairly Tigo’s condensed consolidated balance sheet as of March 31, 2025 and its condensed consolidated statements of operations and comprehensive loss, cash flows, and stockholders’ equity for the three months ended March 31, 2025, and 2024. Operating results for the three months ended March 31, 2025, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2025. The unaudited condensed consolidated financial statements,

presented herein, do not contain all of the required disclosures under GAAP for annual consolidated financial statements. The condensed consolidated balance sheet as of December 31, 2024, has been derived from the audited consolidated balance sheet as of that date. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the SEC on March 20, 2025.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value Measurements

The Company measures its financial assets and liabilities at fair value on a recurring basis using a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Authoritative guidance establishes three levels of the fair value hierarchy as follows:


Level 1:	Quoted market prices in active markets for identical assets or liabilities;
Level 2:	Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and
Level 3:	Fair value measurements derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

The following fair value hierarchy table presents information about the Company’s assets and liabilities measured at fair value on a recurring basis:

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, marketable securities, accounts receivable, accounts payable, and customer deposits approximate fair value due to their short-term nature. As of March 31, 2025, the fair value and carrying value of the Company’s Convertible Promissory Note (Note 7) was $44.2 million and $42.7 million, respectively. The estimated fair value for the Company’s Convertible Promissory Note was based on discounted expected future cash flows using prevailing interest rates which are Level 3 inputs under the fair value hierarchy.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes The income tax provision is calculated for an interim period by distinguishing between elements recognized in the income tax provision through applying an estimated annual effective tax rate to a measure of year-to-date operating results referred to as “ordinary income (or loss),” and discretely recognizing specific events referred to as “discrete items” as they occur. The Company’s effective tax rates for the three months ended March 31, 2025, and 2024 differ from the federal statutory rate of 21% principally as a result of valuation allowances expected to be maintained against the Company’s deferred tax assets. Additionally, the Company recorded a discrete tax expense for the three months ended March 31, 2025, of $0.3 million related to the estimated settlement of a foreign tax examination. During three months ended March 31, 2025, the Italian tax authority initiated a tax examination of the Company’s Italian operations. As of March 31, 2025, the tax examination is close to settlement and the Company has accrued the amount that it expects to incur. The Company did not record income tax expense for the three months ended March 31, 2024.

The entire disclosure for income tax.

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Key estimates in the condensed consolidated financial statements include revenue recognition, fair value of investments, allowance for credit allowances, inventory valuation, impairment of long-lived assets, fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment, product warranty liabilities, incremental borrowing rate for right of use assets and lease liability, valuation allowance on deferred tax assets, assessment of probability of vesting of performance-based equity awards and stock-based compensation, including the underlying fair value of the common stock. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ materially from those estimates due to risks and uncertainties.
Segment Information	Segment Information Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker (“CODM”), or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s CODM is the Chief Executive Officer (the “CEO”). The Company has one business activity — the design, development and sale of solar energy optimization solutions. There are no segment managers who are held accountable for operations, operating results or plans for levels or components below the consolidated unit level. Accordingly, management has determined that the Company has a single operating and reportable segment. The CODM assesses performance for the Company, monitors budget versus actual results and determines how to allocate resources based on consolidated net loss as reported in the condensed consolidated statements of operations and comprehensive loss. There are no other significant expense categories regularly provided to the CODM that are not already included in the primary financial statements herein.
Recently issued accounting pronouncements not yet adopted	Recently issued accounting pronouncements not yet adopted In December 2023, the FASB issued ASU No. 2023-09, “Improvements to Income Tax Disclosures” (“Topic 740”). This ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024, although retrospective application is permitted. Early adoption is also permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently evaluating the impact that adopting this ASU will have on the Company’s income tax-related disclosures. In November 2024, the FASB issued ASU 2024-03, “Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (“Subtopic 220-40”): Disaggregation of Income (Loss) Statement Expenses” (“ASU 2024-03”). ASU 2024-03 requires disaggregation of certain costs and expenses included in each relevant expense caption on the Company’s condensed consolidated statements of operations and comprehensive loss in a separate note to the financial statements at each interim and annual reporting period, including amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization. ASU 2024-04 is effective fiscal years beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.

Convertible promissory note conversion, description		the Convertible Promissory Note may be converted at the option of the note holder into the Company’s common stock or an equivalent equity instrument resulting from a public company event. The conversion price is based on a pre-money valuation divided by the aggregate number of the Company’s outstanding shares at the issuance date and adjusted for any cash dividends paid on the Company’s capital stock. The conversion price and number of conversion shares are subject to standard anti-dilution adjustments. Upon a change of control event the note holder may (i) convert the Convertible Promissory Note immediately prior to the event into the Company’s common stock at a conversion price equal to the lesser of the Convertible Promissory Note’s original conversion price or the price per share of the Company’s common stock implied by the change of control event transaction agreement or (ii) require the redemption of the Convertible Promissory Note in cash, including the payment of a make-whole amount of all unpaid interest that would have otherwise been payable had the Convertible Promissory Note remained outstanding through the maturity date.
Note purchase agreement default description		The Note Purchase Agreement defines events of default as the occurrence of any one of the following; 1) a default in payment of any part of principal or unpaid accrued interest on the Convertible Promissory Note when due and payable; 2) the Company issues a written statement that it is unable to pay its debts as they become due, or the Company files a voluntary petition for bankruptcy or insolvency proceeding, the Company, or its directors or majority shareholders take action looking to the dissolution or liquidation of the Company; 3) the involuntary bankruptcy of the Company defined as the commencement of any proceeding against the Company seeking any bankruptcy reorganization; 4) the Company defaults on any of its performance obligations under the Note Purchase Agreement; 5) any material portion of the assets of the Company or any subsidiary of the Company is seized or a levy is filed against such assets; 6) a default that remains uncured on any other agreement evidencing the indebtedness of the Company or its subsidiaries for an amount of $10 million or more whose terms allow for the acceleration of the repayment of such indebtedness due to the consummation of the transactions contemplated in this Note Purchase Agreement.

Summary of Significant Accounting Policies	Mar. 31, 2025
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The Company’s significant accounting policies are described in Note 2 to its audited consolidated financial statements for the year ended December 31, 2024, which are included in the Company’s Annual Report on Form 10-K filed with the SEC on March 20, 2025. Liquidity and Going Concern In accordance with ASU No. 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“Subtopic 205-40”), the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. As of March 31, 2025, the Company had cash and cash equivalents of $8.5 million and negative net working capital, which we define as current assets less current liabilities, of $6.5 million. The Convertible Promissory Note (as defined in Note 7, “Debt,” below), has an aggregate principal amount outstanding of $50.0 million as of March 31, 2025, and a maturity date of January 9, 2026. As of the date of this filing, the Company does not have sufficient cash, cash equivalents and marketable securities to repay this obligation. Management determined as a result of this evaluation, the Company’s current cash, net working capital position, and the upcoming maturity date of its Convertible Promissory Note, raises substantial doubt about the Company’s ability to continue as a going concern. The Company’s plan is to continue exploring options for raising additional capital through a combination of equity financing to supplement the Company’s liquidity and/or refinancing of the Convertible Promissory Note. The Company's ability to raise capital may be constrained by the price of and demand for the Company’s common stock. Additional capital may not be available on favorable terms or at all, and could further dilute our current stockholders. Management cannot conclude as of the date of this filing that its plans are probable of being successfully implemented. There can be no assurance that the Company will be able to raise sufficient additional capital or obtain financing that will provide it with sufficient liquidity to satisfy its Convertible Promissory Note obligation in January 2026. The condensed consolidated financial statements have been prepared on a basis that assumes the Company will continue as a going concern which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business. Accordingly, the accompanying condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Emerging Growth Company Status The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (JOBS Act). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. Use of Estimates The preparation of the condensed consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Key estimates in the condensed consolidated financial statements include revenue recognition, fair value of investments, allowance for credit allowances, inventory valuation, impairment of long-lived assets, fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment, product warranty liabilities, incremental borrowing rate for right of use assets and lease liability, valuation allowance on deferred tax assets, assessment of probability of vesting of performance-based equity awards and stock-based compensation, including the underlying fair value of the common stock. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ materially from those estimates due to risks and uncertainties. Segment Information Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker (“CODM”), or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s CODM is the Chief Executive Officer (the “CEO”). The Company has one business activity — the design, development and sale of solar energy optimization solutions. There are no segment managers who are held accountable for operations, operating results or plans for levels or components below the consolidated unit level. Accordingly, management has determined that the Company has a single operating and reportable segment. The CODM assesses performance for the Company, monitors budget versus actual results and determines how to allocate resources based on consolidated net loss as reported in the condensed consolidated statements of operations and comprehensive loss. There are no other significant expense categories regularly provided to the CODM that are not already included in the primary financial statements herein. Recently issued accounting pronouncements not yet adopted In December 2023, the FASB issued ASU No. 2023-09, “Improvements to Income Tax Disclosures” (“Topic 740”). This ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024, although retrospective application is permitted. Early adoption is also permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently evaluating the impact that adopting this ASU will have on the Company’s income tax-related disclosures. In November 2024, the FASB issued ASU 2024-03, “Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (“Subtopic 220-40”): Disaggregation of Income (Loss) Statement Expenses” (“ASU 2024-03”). ASU 2024-03 requires disaggregation of certain costs and expenses included in each relevant expense caption on the Company’s condensed consolidated statements of operations and comprehensive loss in a separate note to the financial statements at each interim and annual reporting period, including amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization. ASU 2024-04 is effective fiscal years beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.

(2)

Our net revenues generated from the United States represented 22.2% of our total net revenue for the three months ended March 31, 2025.

Deferred Revenue

Deferred revenue or contract liabilities consists of payments received from customers in advance of revenue recognition for the Company’s products and service. The current portion of deferred revenue represents the unearned revenue that will be earned within 12 months of the balance sheet date. Correspondingly, noncurrent deferred revenue represents the unearned revenue that will be earned after 12 months from the balance sheet date.

The following table summarizes the changes in deferred revenue:


	Three Months Ended March 31,
(in thousands)	2025			2024
Balance at the beginning of the period	$	1,169		$	801
Deferral of revenue		3,801			1,666
Recognition of unearned revenue		(3,592	)		(1,416	)
Balance at the end of the period	$	1,378		$	1,051

As of March 31, 2025, the Company expects to recognize $1.4 million from remaining performance obligations over a weighted average term of 3.2 years. The Company recognized approximately $0.3 million and $0.2 million in revenue that was included in the beginning contract liabilities balance during the three months ended March 31, 2025, and 2024, respectively.

Product Warranty

The Company estimates the cost of its warranty obligations based on several key estimates: the warranty period (which vary from 5 to 25 years depending on the product), its historical experience of known product failure rates, use of materials to repair or replace defective products and parts, and service delivery costs incurred in correcting product failures. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise. Should the actual experience relative to these factors differ from the estimates, the Company may be required to record additional warranty reserves. Product warranty costs are recorded as expense to cost of revenue based on customer history, historical information and current trends.

The following table summarizes the changes in product warranty liability:


	Three Months Ended March 31,
(in thousands)	2025			2024
Balance at the beginning of the period	$	5,798		$	5,632
Provision for warranty issued during period		363			138
Changes in estimate		1,280			(197	)
Settlements		(117	)		(94	)
Balance at the end of the period	$	7,324		$	5,479

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

At-The-Market Offering Program

In November 2024, we entered into an At-The-Market Offering Agreement (the “ATM Agreement”) with Craig-Hallum Capital Group LLC (the “Sales Agent”), allowing for the sale of common stock with an aggregate gross offering price of up to $14.2 million (the “2024 ATM Program”). Under the ATM Agreement, the Sales Agent may sell shares in an “at-the-market” offering under Rule 415(a)(4) of the Securities Act, including sales on Nasdaq or other trading markets, to or through market makers, directly to the Sales Agent as principal, or in negotiated transactions at prevailing market prices. The offering of Shares pursuant to the ATM Agreement will terminate upon (a) five business days’ advance notice from the Company to the Sales Agent or five business days’ advance notice from the Sales Agent to the Company or (b) otherwise by mutual agreement of the parties pursuant to the terms of the ATM Agreement. Sales under the 2024 ATM Program are subject to a maximum commission of up to 3.0% of the gross proceeds per share sold through the Sales Agent.

The following is a summary of the shares issued under our 2024 ATM Program during the three months ended March 31, 2025 (in thousands except average price per share):


Period Ended	Shares Issued		Average Net Price Per Share(1)		Gross Proceeds		Net Proceeds

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Employment Agreements

The Company entered into employment agreements with key personnel providing compensation and severance in certain circumstances, as defined in the respective employment agreements.

Legal

In the normal course of business, the Company may become involved in litigation or legal disputes that are not covered by insurance. While the Company intends to vigorously defend itself with respect to such disputes, any potential outcomes resulting from such claims would be inherently difficult to quantify. The Company makes a provision for a liability relating to legal matters when it is both probable that a liability has been incurred, and the amount of the loss can be reasonably estimated. During the three months ended March 31, 2025, the Company did not record a material loss with respect to any legal claims or other legal matters arising in the normal course of business.

Indemnification Agreements

From time to time, in its normal course of business, the Company may indemnify other parties with which it enters into contractual relationships, including customers, lessors and parties to other transactions with the Company. The Company may agree to hold other parties harmless against specific losses, such as those that could arise from third-party claims or a breach of representation or covenant. It may not be possible to determine the maximum potential amount of liability under such indemnification agreements due to the unique facts and circumstances that are likely to be involved in each particular claim and indemnification provision. In addition, we believe the likelihood is remote that payments under any indemnification agreements described above will have a material effect on the Company’s condensed consolidated financial statements.

The Company has also indemnified its Directors and Executive Officers, to the extent legally permissible, against all liabilities reasonably incurred in connection with any action in which such individual may be involved by reason of such individual being or having been a Director or Executive Officer.

The Company believes the current estimated fair value of any obligation from these indemnification agreements is minimal; therefore, these condensed consolidated financial statements do not include a liability for potential indemnification-related obligations at March 31, 2025.

Long-term debt, net of unamortized debt discount and issuance costs	$	—		$	40,511

On January 9, 2025, the Convertible Promissory Note was reclassified from non-current liabilities to current liabilities as the maturity date falls within the twelve months of the reporting date.

Convertible Promissory Notes

On January 9, 2023, the Company entered into the Note Purchase Agreement (“Note Purchase Agreement”) with L1 Energy Capital Management S.a.r.l. (“L1 Energy”) pursuant to which the Company issued the Convertible Promissory Note in the aggregate principal amount of $50.0 million (the “Convertible Promissory Note”). Outstanding borrowings under the Convertible Promissory Note bears interest at a rate of 5.0% per year. The principal amount of the Convertible Promissory Note is due at the maturity date of January 9, 2026, and interest is payable semiannually. As of March 31, 2025, there was $0.6 million of accrued interest in the condensed consolidated balance sheet.

Under the terms of the Note Purchase Agreement, the Convertible Promissory Note may be converted at the option of the note holder into the Company’s common stock or an equivalent equity instrument resulting from a public company event. The conversion price is based on a pre-money valuation divided by the aggregate number of the Company’s outstanding shares at the issuance date and adjusted for any cash dividends paid on the Company’s capital stock. The conversion price and number of conversion shares are subject to standard anti-dilution adjustments. Upon a change of control event the note holder may (i) convert the Convertible Promissory Note immediately prior to the event into the Company’s common stock at a conversion price equal to the lesser of the Convertible Promissory Note’s original conversion price or the price per share of the Company’s common stock implied by the change of control event transaction agreement or (ii) require the redemption of the Convertible Promissory Note in cash, including the payment of a make-whole amount of all unpaid interest that would have otherwise been payable had the Convertible Promissory Note remained outstanding through the maturity date. The Company’s obligations under the Note Purchase Agreement may be accelerated, subject to customary grace and cure periods, upon the occurrence of an event of default. The Note Purchase Agreement defines events of default as the occurrence of any one of the following; 1) a default in payment of any part of principal or unpaid accrued interest on the Convertible Promissory Note when due and payable; 2) the Company issues a written statement that it is unable to pay its debts as they become due, or the Company files a voluntary petition for bankruptcy or insolvency proceeding, the Company, or its directors or majority shareholders take action looking to the dissolution or liquidation of the Company; 3) the involuntary bankruptcy of the Company defined as the commencement of any proceeding against the Company seeking any bankruptcy reorganization; 4) the Company defaults on any of its performance obligations under the Note Purchase Agreement; 5) any material portion of the assets of the Company or any subsidiary of the Company is seized or a levy is filed against such assets; 6) a default that remains uncured on any other agreement evidencing the indebtedness of the Company or its subsidiaries for an amount of $10 million or more whose terms allow for the acceleration of the repayment of such indebtedness due to the consummation of the transactions contemplated in this Note Purchase Agreement.

Future aggregate principal maturities of debt are as follows as of March 31, 2025 (in thousands):
