Dec. 31, 2025
Accounting Policies [Abstract]
Basis of Accounting and Presentation	Basis of Accounting and Presentation The consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Reclassifications	Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation.
Non-Controlling Interests	Non-Controlling Interests The non-controlling interests on the consolidated statements of operations represented a portion of earnings or loss attributable to the economic interests in the Company’s former subsidiary, Shoals Parent LLC, formerly held by direct or indirect holders of LLC Interests and our Class B common stock, including the founder and certain current and former executive officers, employees and their respective permitted transferees (the “Continuing Equity Owners”). Activity related to non-controlling interests on the Statements of Changes in Members’ / Stockholders’ Equity represents activity related to the portion of net assets of the Company attributable to the Continuing Equity Owners, based on the portion of the LLC Interests owned by such unit holders.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates. Significant estimates include revenue recognition, allowance for credit losses, useful lives of property, plant and equipment and other intangible assets, impairment of long-lived assets, allowance for obsolete or slow moving inventory, valuation allowance on deferred tax assets, equity-based compensation expense and warranty liability.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers cash and cash equivalents to include cash on hand, cash held in demand deposit accounts, and all highly liquid financial instruments purchased with a maturity of three months or less.
Accounts Receivable and Allowance for Credit Losses	Accounts Receivable and Allowance for Credit Losses Accounts receivable is comprised of amounts billed to customers, net of an allowance for credit losses. The allowance for credit losses is estimated by management and is based on historical experience, current conditions and reasonable forecasts. Periodically, management reviews the accounts receivable balances of its customers and adjusts the allowance based on current circumstances and charges off uncollectible receivables when all attempts to collect have failed, although collection efforts may continue.
Unbilled Receivables	Unbilled Receivables Unbilled receivables arise when the Company recognizes revenue for amounts which cannot yet be billed under terms of the contract with the customer.
Inventory	Inventory Inventories consist of raw materials, work in process, and finished goods. Inventories are stated at the lower of cost or net realizable value. Cost is calculated using the first-in first-out method. Provisions are made to reduce excess or obsolete inventories to their estimated net realizable values.
Property, Plant, and Equipment	Property, Plant, and Equipment Property, plant, and equipment acquired in acquisitions are recorded at fair value at the date of acquisition; all other property, plant and equipment are recorded at cost, net of accumulated depreciation. Improvements, betterments and replacements which significantly extend the life of an asset are capitalized. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Repair and maintenance costs are expensed as incurred. A gain or loss on the sale of property, plant and equipment is calculated as the difference between the cost of the asset disposed of, net of accumulated depreciation, and the sales proceeds received. A gain or loss on an asset disposal is recognized in the period that the sale occurs.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets When events, circumstances or operating results indicate that the carrying values of long-lived assets might not be recoverable through future operations, the Company prepares projections of the undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the projections indicate that the recorded amounts are not expected to be recoverable, such amounts are reduced to estimated fair value. Fair value is estimated based upon internal evaluation of each asset that includes quantitative analyses of net revenue and cash flows, review of recent sales of similar assets and market responses based upon discussions in connection with offers received from potential buyers.
Goodwill	Goodwill Goodwill is assessed using either a qualitative assessment or quantitative approach to determine whether it is more likely than not that the fair value of the reporting unit is less than the carrying amount. The qualitative assessment evaluates factors including macroeconomic conditions, industry-specific and company-specific considerations, legal and regulatory environments, and historical performance. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying value, a quantitative assessment is performed. Otherwise, no further assessment is required. The quantitative approach compares the estimated fair value of the reporting units to its carrying amount, including goodwill. Impairment is indicated if the estimated fair value of the reporting unit is less than the carrying amount of the reporting unit, and an impairment charge is recognized for the differential. The Company completes its annual goodwill impairment test as of October 1 each year.
Amortizable and Other Intangible Assets	Amortizable and Other Intangible Assets The Company amortizes identifiable intangible assets consisting of customer relationships, developed technology, trade names, backlog and noncompete agreements because these assets have finite lives. The Company’s intangible assets with finite lives are amortized on a straight‐line basis over the estimated useful lives. The basis of amortization approximates the pattern in which the assets are utilized over their estimated useful lives. The Company reviews for impairment indicators of finite-lived intangibles, as described in the “Impairment of Long-Lived Assets” significant accounting policy.
Deferred Offering Costs	Deferred Offering Costs Deferred offering costs consist primarily of registration fees, filing fees, listing fees, specific legal and accounting costs and transfer agent fees, which are direct and incremental fees related to the IPO and secondary offerings.
Deferred Financing Costs	Deferred Financing Costs Costs incurred to issue debt are capitalized and recorded net of the related debt and amortized using the effective interest method as a component of interest expense over the terms of the related debt agreement.
Treasury Stock	Treasury Stock The Company records treasury stock activities under the cost method whereby the cost of the acquired stock is recorded as treasury stock. The Company’s accounting policy upon the formal retirement of treasury stock is to deduct the par value from common stock and to reflect any excess of cost over par value as a reduction to additional paid-in capital (to the extent created by previous issuances of the shares) and then retained earnings.
Revenue Recognition	Revenue Recognition The Company recognizes revenue primarily from the sale of EBOS systems and components. The Company determines its revenue recognition through the following steps: (i) identification of the contract or contracts with a customer, (ii) identification of the performance obligations within the contract, (iii) determination of the transaction price, (iv) allocation of the transaction price to the performance obligations within the contract, and (v) recognition of revenue as the performance obligation has been satisfied. The Company’s contracts with customers predominately are accounted for as one performance obligation, as the majority of the obligations under the contracts relate to a single project. For each contract entered into, the Company determines the transaction price based on the consideration expected to be received, net of any variable consideration or options. The transaction price identified is allocated to each distinct performance obligation to deliver a good or service based on the relative standalone selling prices. Management has concluded that the prices negotiated with each individual customer are representative of the standalone selling price of the product. Some of the Company’s sales agreements have rebates and volume-based discounts with tiered pricing which are prospective in nature. We concluded that in these situations, the incentives can represent variable consideration or options, depending upon the specifics of the agreement. In the event the agreement contains an option, the option is considered a material right and, therefore, included in the accounting for the initial arrangement. We estimate the average anticipated discount over the lifetime of the contract, and apply that discount to each contract. On a quarterly basis, we review our estimates and, if needed, updates are made and changes are applied prospectively. The Company primarily recognizes revenue over time as a result of the continuous transfer of control of its product to the customer using the output method based on units manufactured. This continuous transfer of control to the customer is supported by clauses in the contracts that provide rights to payment of the transaction price associated with work performed to date on products that do not have an alternative use to the Company. Management believes that recognizing revenue using the output method based on units manufactured best depicts the extent of transfer of control to the customer. In certain instances the promised goods do have an alternative use. In these instances, revenue is recognized when the customer obtains control of the product. Contracts of this nature typically include customer acceptance clauses, which results in revenue recognition occurring upon customer acceptance. Depending on the size of project, the manufacturing process generally takes from less than one week to four months to complete production. The accounting for each contract involves a judgmental process of estimating total sales, costs, and profit for each performance obligation. Cost of revenue is recognized based on the unit of production. The amount reported as revenue is determined by adding a proportionate amount of the estimated profit to the amount reported as cost of revenue. The Company has elected to adopt certain practical expedients and exemptions as allowed under the new revenue recognition guidance such as (i) recording sales commissions as incurred because the amortization period is less than one year, (ii) excluding any collected sales tax amounts from the calculation of revenue, and (iii) accounting for shipping and handling activities that are incurred after the customer has obtained control of the product as fulfillment costs rather than a separate service provided to the customer for which consideration would need to be allocated (see Shipping and Handling).
Shipping and Handling	Shipping and Handling The Company accounts for shipping and handling related to contracts with customers as costs to fulfill its promise to transfer the associated products. Accordingly, payment by the Company’s customers for shipping and handling costs for delivery of the Company’s products are recorded as a component of revenue in the accompanying consolidated statements of operations.
Concentrations	Concentrations The Company has cash deposited at certain financial institutions which, at times, may exceed the limits provided by the Federal Deposit Insurance Corporation (“FDIC”). The Company has not experienced any losses on such amount and believes it is not subject to significant credit risk related to cash balances.
Fair Value	Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company follows a fair value hierarchy which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Three levels of inputs may be used to measure fair value, as follows: •Level 1 – Quoted prices in active markets for identical assets or liabilities. •Level 2 – Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. •Level 3 – Unobservable inputs that are supported by little or no market activity that are significant to the fair value of the assets or liabilities. The fair values of the Company’s cash and cash equivalents, accounts receivable, and accounts payable approximate their carrying values due to their short maturities. The carrying value of the Company’s long-term debt approximates fair value and is considered level 2, as it is based on current market rates at which the Company could borrow funds with similar terms.
Income Taxes	Income Taxes The Company is taxed as a corporation for U.S. federal and state income tax purposes. Prior to July 1, 2023, the Company’s sole material asset was Shoals Parent LLC, which was a limited liability company that was taxed as a partnership for US federal and certain state and local income tax purposes. Shoals Parent LLC’s net taxable income and related tax credits, if any, were passed through to its members and included in the member’s tax returns. The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are calculated by applying existing tax laws and the rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the year of the enacted rate change. In assessing the realizability of deferred tax assets, management considers whether it is more-likely-than-not that the deferred tax assets will be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, carryback potential if permitted under the tax law, and results of recent operations. The Company accounts for uncertainty in income taxes using a recognition and measurement threshold for tax positions taken or expected to be taken in a tax return, which are subject to examination by federal and state taxing authorities. The tax benefit from an uncertain tax position is recognized when it is more likely than not that the position will be sustained upon examination by taxing authorities based on the technical merits of the position. The amount of the tax benefit recognized is the largest amount of the benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The effective tax rate and the tax basis of assets and liabilities reflect management’s estimates of the ultimate outcome of various tax uncertainties. The Company recognizes penalties and interest related to uncertain tax positions within the income tax expense financial statement caption in the accompanying consolidated statements of operations. The Company did not have any material interest and penalties during the years ended December 31, 2025, 2024 and 2023. The Company files U.S. federal and certain state income tax returns. The income tax returns of the Company are subject to examination by U.S. federal and state taxing authorities for various time periods, depending on each jurisdictions’ rules, beginning generally after the income tax returns are filed.
Product Warranty	Product Warranty The Company offers an assurance type warranty for its products against manufacturer defects and does not contain a service element. For these assurance type warranties, a provision for estimated future costs related to warranty expense is recorded when they are probable and reasonably estimable. This provision is based on historical information on the nature, frequency and average cost of claims for each product line. When little or no experience exists for an immature product line, the estimate is based on comparable product lines. Specific liabilities are established once an issue is identified with the amounts for such liabilities based on the estimated cost of correction. These estimates are re-evaluated on an ongoing basis using best-available information and revisions to estimates are made as necessary.
Equity-Based Compensation	Equity-Based Compensation The Company recognizes equity-based compensation expense based on the equity award’s grant date fair value. The determination of the fair value of equity awards issued to employees of the Company is based upon the closing market price of the Company’s common stock on the day prior to the grant date. Equity-based compensation expense related to performance stock units is recognized if it is probable that the performance condition will be satisfied. The Company accounts for forfeitures as they occur. The grant date fair value of each unit is amortized on a straight-line basis over the requisite service period, including those units with graded vesting. However, the amount of equity-based compensation at any date is at least equal to the portion of the grant date fair value of the award that is vested.
Earnings per Share (“EPS”)	Earnings per Share (“EPS”) Basic EPS is computed by dividing net income available to common stockholders by the weighted average shares outstanding during the period. Diluted EPS takes into account the potential dilution that could occur if securities or other contracts to issue shares, such as unvested restricted stock units, were exercised and converted into shares. Diluted EPS is computed by dividing net income available to common stockholders by the weighted average shares outstanding during the period, increased by the number of additional shares that would have been outstanding if the potential shares had been issued and were dilutive.
Segment Reporting	Segment Reporting ASC 280 (“Segment Reporting”) establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company manages its business on the basis of one operating and reportable segment and derives revenues from selling its product.
Foreign Currency Remeasurement	Foreign Currency Remeasurement The reporting currency of the Company and its subsidiaries is the United States dollar. Remeasurement gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included the consolidated statements of operations.
Advertising Expenses	Advertising Expenses Advertising expenses are expensed as incurred.
Research and Development Expenses	Research and Development Expenses Research and development expenses are expensed as incurred.
New Accounting Standards	New Accounting Standards Adopted In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-09 for the year ended December 31, 2025, and applied the new disclosure requirements prospectively to the current annual period. Prior period disclosures have not been adjusted to reflect the new disclosure requirements. See Note 16 Income Taxes in the accompanying notes to the consolidated financial statements for further detail. Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03. In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which modernizes the accounting for internal-use software to current development practices, clarifies when to begin capitalizing costs, and enhances disclosure requirements. This update is effective for interim and annual periods beginning after December 15, 2027, with early adoption permitted. ASU 2025-06 is not expected to significantly change our current accounting for internal-use software. In December 2025, the FASB issued ASU 2025-10, Accounting for Government Grants Received by Business Entities, to establish guidance on the recognition, measurement, and presentation of government grants received by business entities. The new guidance leverages the principles in the accounting framework for government assistance in International Accounting Standard 20 "Accounting for Government Grants and Disclosure of Government Assistance". The new guidance is effective for public business entities in annual periods beginning after December 15, 2028, with early adoption permitted. ASU 2025-10 is not expected to significantly change our current accounting for incentives from federal, state, and local governments. Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s consolidated financial statements.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2025

The consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation.

Non-Controlling Interests

The non-controlling interests on the consolidated statements of operations represented a portion of earnings or loss attributable to the economic interests in the Company’s former subsidiary, Shoals Parent LLC, formerly held by direct or indirect holders of LLC Interests and our Class B common stock, including the founder and certain current and former executive officers, employees and their respective permitted

transferees (the “Continuing Equity Owners”). Activity related to non-controlling interests on the Statements of Changes in Members’ / Stockholders’ Equity represents activity related to the portion of net assets of the Company attributable to the Continuing Equity Owners, based on the portion of the LLC Interests owned by such unit holders.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates. Significant estimates include revenue recognition, allowance for credit losses, useful lives of property, plant and equipment and other intangible assets, impairment of long-lived assets, allowance for obsolete or slow moving inventory, valuation allowance on deferred tax assets, equity-based compensation expense and warranty liability.

Cash and Cash Equivalents

The Company considers cash and cash equivalents to include cash on hand, cash held in demand deposit accounts, and all highly liquid financial instruments purchased with a maturity of three months or less.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable is comprised of amounts billed to customers, net of an allowance for credit losses. The allowance for credit losses is estimated by management and is based on historical experience, current conditions and reasonable forecasts. Periodically, management reviews the accounts receivable balances of its customers and adjusts the allowance based on current circumstances and charges off uncollectible receivables when all attempts to collect have failed, although collection efforts may continue.

Unbilled Receivables

Unbilled receivables arise when the Company recognizes revenue for amounts which cannot yet be billed under terms of the contract with the customer.

Inventory

Inventories consist of raw materials, work in process, and finished goods. Inventories are stated at the lower of cost or net realizable value. Cost is calculated using the first-in first-out method. Provisions are made to reduce excess or obsolete inventories to their estimated net realizable values.

Property, Plant, and Equipment

Property, plant, and equipment acquired in acquisitions are recorded at fair value at the date of acquisition; all other property, plant and equipment are recorded at cost, net of accumulated depreciation. Improvements, betterments and replacements which significantly extend the life of an asset are capitalized. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Repair and maintenance costs are expensed as incurred.

A gain or loss on the sale of property, plant and equipment is calculated as the difference between the cost of the asset disposed of, net of accumulated depreciation, and the sales proceeds received. A gain or loss on an asset disposal is recognized in the period that the sale occurs.

Impairment of Long-Lived Assets

When events, circumstances or operating results indicate that the carrying values of long-lived assets might not be recoverable through future operations, the Company prepares projections of the undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the projections indicate that the recorded amounts are not expected to be recoverable, such amounts are reduced to estimated fair value. Fair value is estimated based upon internal evaluation of each asset that includes quantitative analyses of net revenue and cash flows, review of recent sales of similar assets and market responses based upon discussions in connection with offers received from potential buyers.

Goodwill

Goodwill is assessed using either a qualitative assessment or quantitative approach to determine whether it is more likely than not that the fair value of the reporting unit is less than the carrying amount. The qualitative assessment evaluates factors including macroeconomic conditions, industry-specific and company-specific considerations, legal and regulatory environments, and historical performance. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying value, a quantitative assessment is performed. Otherwise, no further assessment is required. The quantitative approach compares the estimated fair value of the reporting units to its carrying amount, including goodwill. Impairment is indicated if the estimated fair value of the reporting unit is less than the carrying amount of the reporting unit, and an impairment charge is recognized for the differential.

The Company completes its annual goodwill impairment test as of October 1 each year.

Amortizable and Other Intangible Assets

The Company amortizes identifiable intangible assets consisting of customer relationships, developed technology, trade names, backlog and noncompete agreements because these assets have finite lives. The Company’s intangible assets with finite lives are amortized on a straight‐line basis over the estimated useful lives. The basis of amortization approximates the pattern in which the assets are utilized over their estimated useful lives. The Company reviews for impairment indicators of finite-lived intangibles, as described in the “Impairment of Long-Lived Assets” significant accounting policy.

Deferred Offering Costs

Deferred offering costs consist primarily of registration fees, filing fees, listing fees, specific legal and accounting costs and transfer agent fees, which are direct and incremental fees related to the IPO and secondary offerings.

Deferred Financing Costs

Costs incurred to issue debt are capitalized and recorded net of the related debt and amortized using the effective interest method as a component of interest expense over the terms of the related debt agreement.

Treasury Stock

The Company records treasury stock activities under the cost method whereby the cost of the acquired stock is recorded as treasury stock. The Company’s accounting policy upon the formal retirement of treasury stock is to deduct the par value from common stock and to reflect any excess of cost over par value as a

reduction to additional paid-in capital (to the extent created by previous issuances of the shares) and then retained earnings.

Revenue Recognition

The Company recognizes revenue primarily from the sale of EBOS systems and components. The Company determines its revenue recognition through the following steps: (i) identification of the contract or contracts with a customer, (ii) identification of the performance obligations within the contract, (iii) determination of the transaction price, (iv) allocation of the transaction price to the performance obligations within the contract, and (v) recognition of revenue as the performance obligation has been satisfied.

The Company’s contracts with customers predominately are accounted for as one performance obligation, as the majority of the obligations under the contracts relate to a single project. For each contract entered into, the Company determines the transaction price based on the consideration expected to be received, net of any variable consideration or options. The transaction price identified is allocated to each distinct performance obligation to deliver a good or service based on the relative standalone selling prices. Management has concluded that the prices negotiated with each individual customer are representative of the standalone selling price of the product.

Some of the Company’s sales agreements have rebates and volume-based discounts with tiered pricing which are prospective in nature. We concluded that in these situations, the incentives can represent variable consideration or options, depending upon the specifics of the agreement. In the event the agreement contains an option, the option is considered a material right and, therefore, included in the accounting for the initial arrangement. We estimate the average anticipated discount over the lifetime of the contract, and apply that discount to each contract. On a quarterly basis, we review our estimates and, if needed, updates are made and changes are applied prospectively.

Shipping and Handling

The Company accounts for shipping and handling related to contracts with customers as costs to fulfill its promise to transfer the associated products. Accordingly, payment by the Company’s customers for shipping and handling costs for delivery of the Company’s products are recorded as a component of revenue in the accompanying consolidated statements of operations.

Concentrations

The Company has cash deposited at certain financial institutions which, at times, may exceed the limits provided by the Federal Deposit Insurance Corporation (“FDIC”). The Company has not experienced any losses on such amount and believes it is not subject to significant credit risk related to cash balances.

Fair Value

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company follows a fair value hierarchy which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Three levels of inputs may be used to measure fair value, as follows:

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

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

•Level 3 – Unobservable inputs that are supported by little or no market activity that are significant to the fair value of the assets or liabilities.

The fair values of the Company’s cash and cash equivalents, accounts receivable, and accounts payable approximate their carrying values due to their short maturities. The carrying value of the Company’s long-term debt approximates fair value and is considered level 2, as it is based on current market rates at which the Company could borrow funds with similar terms.

Income Taxes

The Company is taxed as a corporation for U.S. federal and state income tax purposes. Prior to July 1, 2023, the Company’s sole material asset was Shoals Parent LLC, which was a limited liability company that was taxed as a partnership for US federal and certain state and local income tax purposes. Shoals Parent

LLC’s net taxable income and related tax credits, if any, were passed through to its members and included in the member’s tax returns.

The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are calculated by applying existing tax laws and the rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the year of the enacted rate change.

In assessing the realizability of deferred tax assets, management considers whether it is more-likely-than-not that the deferred tax assets will be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, carryback potential if permitted under the tax law, and results of recent operations.

The Company accounts for uncertainty in income taxes using a recognition and measurement threshold for tax positions taken or expected to be taken in a tax return, which are subject to examination by federal and state taxing authorities. The tax benefit from an uncertain tax position is recognized when it is more likely than not that the position will be sustained upon examination by taxing authorities based on the technical merits of the position. The amount of the tax benefit recognized is the largest amount of the benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The effective tax rate and the tax basis of assets and liabilities reflect management’s estimates of the ultimate outcome of various tax uncertainties. The Company recognizes penalties and interest related to uncertain tax positions within the income tax expense financial statement caption in the accompanying consolidated statements of operations. The Company did not have any material interest and penalties during the years ended December 31, 2025, 2024 and 2023.

The Company files U.S. federal and certain state income tax returns. The income tax returns of the Company are subject to examination by U.S. federal and state taxing authorities for various time periods, depending on each jurisdictions’ rules, beginning generally after the income tax returns are filed.

Product Warranty

The Company offers an assurance type warranty for its products against manufacturer defects and does not contain a service element. For these assurance type warranties, a provision for estimated future costs related to warranty expense is recorded when they are probable and reasonably estimable. This provision is based on historical information on the nature, frequency and average cost of claims for each product line. When little or no experience exists for an immature product line, the estimate is based on comparable product lines. Specific liabilities are established once an issue is identified with the amounts for such liabilities based on the estimated cost of correction. These estimates are re-evaluated on an ongoing basis using best-available information and revisions to estimates are made as necessary.

Equity-Based Compensation

The Company recognizes equity-based compensation expense based on the equity award’s grant date fair value. The determination of the fair value of equity awards issued to employees of the Company is based upon the closing market price of the Company’s common stock on the day prior to the grant date. Equity-based compensation expense related to performance stock units is recognized if it is probable that the performance

condition will be satisfied. The Company accounts for forfeitures as they occur. The grant date fair value of each unit is amortized on a straight-line basis over the requisite service period, including those units with graded vesting. However, the amount of equity-based compensation at any date is at least equal to the portion of the grant date fair value of the award that is vested.

Earnings per Share (“EPS”)

Basic EPS is computed by dividing net income available to common stockholders by the weighted average shares outstanding during the period. Diluted EPS takes into account the potential dilution that could occur if securities or other contracts to issue shares, such as unvested restricted stock units, were exercised and converted into shares. Diluted EPS is computed by dividing net income available to common stockholders by the weighted average shares outstanding during the period, increased by the number of additional shares that would have been outstanding if the potential shares had been issued and were dilutive.

Segment Reporting

ASC 280 (“Segment Reporting”) establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance.

New Accounting Standards

Adopted

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-09 for the year ended December 31, 2025, and applied the new disclosure requirements prospectively to the current annual period. Prior period disclosures have not been adjusted to reflect the new disclosure requirements. See Note 16 Income Taxes in the accompanying notes to the consolidated financial statements for further detail.

Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which modernizes the accounting for internal-use software to current development practices, clarifies when to begin capitalizing costs, and enhances disclosure requirements. This update is effective for interim and annual periods beginning after December 15, 2027, with early adoption permitted. ASU 2025-06 is not expected to significantly change our current accounting for internal-use software.

In December 2025, the FASB issued ASU 2025-10, Accounting for Government Grants Received by Business Entities, to establish guidance on the recognition, measurement, and presentation of government grants received by business entities. The new guidance leverages the principles in the accounting framework for government assistance in International Accounting Standard 20 "Accounting for Government Grants and Disclosure of Government Assistance". The new guidance is effective for public business entities in annual periods beginning after December 15, 2028, with early adoption permitted. ASU 2025-10 is not expected to significantly change our current accounting for incentives from federal, state, and local governments.

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s consolidated financial statements.
