Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Accounting and Presentation The accompanying consolidated financial statements were prepared on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). Reclassifications Beginning in the third quarter of 2023, the Company reclassified amounts recorded for amortization of certain acquired intangible assets in prior presentations from Total operating expenses under the caption "Depreciation and amortization" to Total cost of revenue under the caption "Amortization of developed technology" in the consolidated statements of operations. The Company believes this presentation enhances the comparability of the Company’s financial statements to industry peers. This reclassification resulted in $14.6 million recorded to Amortization of developed technology within Total cost of revenue and a $14.6 million decrease to Depreciation and amortization within Total operating expenses during the year ended December 31, 2022. This reclassification did not impact the Company’s operating income (loss), net income (loss) or earnings (loss) per share for any current or historical periods. These reclassifications also did not impact the consolidated balance sheets or consolidated statements of cash flows for the dates and annual periods presented. Revenue in 2023, excludes a Brazil value-added tax benefit, Imposto sobre Circulação de Mercadorias e Servicos (“ICMS”), that has been reclassified and included in cost of revenues in the current year. For the year ended December 31, 2023, the Brazil ICMS value-added tax benefit was $23.2 million. For the year ended December 31, 2022, an ICMS benefit of $12.3 million was included in revenues. This reclassification in the current year had no impact on the Company’s gross profit, income (loss) from operations, net income or income (loss) per common share in the current period. These reclassifications also did not impact the consolidated balance sheets or consolidated statements of cash flows. Principles of Consolidation The consolidated financial statements include the accounts of Array Technologies, Inc. and its Subsidiaries. All intercompany accounts and transactions have been eliminated upon consolidation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Although management believes its estimates are reasonable, actual results could differ from those estimates. Impact of the Ongoing Russian-Ukraine Conflict The ongoing Russian-Ukraine conflict has reduced the availability of material that can be sourced in Europe and, as a result, increased logistics costs for the procurement of certain inputs and materials used in our products. We do not know the ultimate severity or duration of the conflict, but we continue to monitor the situation and evaluate our procurement strategy and supply chain as to reduce any negative impact on our business, financial condition and results of operations. Impact of Attacks on Shipping in the Red Sea Houthi rebels in Yemen have significantly stepped-up attacks against commercial vessels in the Bab-el-Mandeb strait between the Arabian peninsula and the Horn of Africa since late November of 2023, which has led to many shipping companies pausing shipments through the Suez Canal and the Red Sea. Many of these shipments are being redirected around the Cape of Good Hope in South Africa, adding between 3,000 – 3,500 nautical miles to routes connecting Europe with Asia. As an additional result of the reroute, certain ports could see crowding and delays in unloading shipments. We do not yet know the duration of these disruptions or the severity of their impact on our operations, but we continue to monitor the situation and evaluate our procurement strategy and supply chain to reduce any negative impact on our business, financial condition and results of operations. Inflation Inflationary pressures are expected to persist, at least in the near-term, and may negatively impact our results of operations. To mitigate the inflationary pressures on our business, we have implemented selective price increases in certain markets, accelerated productivity initiatives and expanded our supplier base, while continuing to execute on overhead cost containment practices. Vendor Rebates On August 16, 2022, the Inflation Reduction Act of 2022 (“IRA”) was enacted into law, which includes numerous green energy credits. The 45X Advanced Manufacturing Production Tax Credit (“45X Credit”) was established as part of the IRA. The 45X Credit is a per-unit tax credit that is earned over time for each clean energy component domestically produced and sold by a manufacturer. The Company has, and will continue to, enter into arrangements with torque tube manufacturing vendors that produce 45X Credit eligible parts, in which the vendors agree to share a portion of the benefit received related to Array purchases, in the form of “Vendor Rebates”. The Company accounts for these Vendor Rebates as a reduction of the purchase prices of the vendors’ products and therefore a reduction of inventory until the inventory is sold, at which time the Company recognizes such rebates as a reduction of cost of revenues on the consolidated statements of operations. Rebates related to purchases that were made prior to the execution of the agreements are deferred and recognized as a reduction of the prices of future purchases. During the three months ended December 31, 2023, the Company had accumulated a total of $49.9 million in Vendor Rebates from current year activity, of which $48.4 million was outstanding and included in Prepaid expenses and other, and $40.6 million of deferred consideration was included in Other current liabilities, on the consolidated balance sheet as of December 31, 2023. Foreign Currency Translation Our foreign subsidiaries have functional currencies that are different than our reporting currency. When translating balances from the functional currency to the reporting currency, assets and liabilities are translated into U.S. dollars at period end exchange rates, retained earnings is translated at historical rates, and income, expenses, and cash flow items are translated at average exchange rates prevailing during the period. Translation adjustments for these subsidiaries are accumulated within accumulated other comprehensive income. In situations when a foreign subsidiary has a local currency that is different than the functional currency, monetary assets and liabilities are translated into the functional currency at the period end exchange rates, and non-monetary assets and the related income statement effects are translated into the functional currency using historical rates. Gains and losses that result from remeasurement from a local currency to the functional currency are included in earnings. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. We regularly maintain cash balances that exceed insured amounts, but we have experienced no losses associated with these amounts to date. Accounts Receivable The Company’s accounts receivable are due primarily from solar contractors across the U.S. and internationally. Credit is extended in the normal course of business based on evaluation of a customer’s financial condition and, generally, collateral is not required. Trade receivables consist of uncollateralized customer obligations due under normal trade terms requiring payment within 30 to 60 days of the invoice date. Management regularly reviews outstanding accounts receivable and provides for estimated credit losses through an estimate of expected credit losses valuation account. The Company adopted Accounting Standards Updated (“ASU”) No. 2016-13, Financial Instruments - Credit Losses, on January 1, 2021, which revised the methodology for measuring credit losses on financial instruments including trade accounts receivable and the timing of when such losses are recorded. The Company adopted ASU 2016-13 using a modified retrospective approach with a cumulative effect adjustment to the opening balance of retained earnings, which had no impact on the consolidated financial statements. The allowance for credit losses is a valuation account that is deducted from a financial asset’s amortized cost to present the net amount we expect to collect from the asset. We estimate allowances for credit losses using relevant available information from both internal and external sources. We monitor the estimated credit losses associated with our trade accounts receivable and unbilled accounts receivable based primarily on our collection history and the delinquency status of amounts owed to us, which we determine based on the aging of such receivables. In evaluating the level of established reserves, management makes judgments regarding the customers’ ability to make required payments, economic events, and other factors. As the financial conditions of these customers change, circumstances develop, or additional information becomes available, adjustments to the valuation account may be required. When deemed uncollectible, the receivable is charged against the valuation account for credit losses or directly written off. Unbilled receivables represent temporary timing differences between shipments made and billing milestones achieved and are recorded in the accounts receivable balances. Such amounts have not been billed due to pending commercial criteria such as billing on a specified date of the month or upon completion of mega-watt deliveries. Unbilled receivables are invoiced once the underlying commercial criteria have been met and we expect payment within 30 to 60 days. Inventories Inventories consist of raw materials and finished goods and are stated at the lower of cost or estimated net realizable value using primarily the moving average cost method that approximates the FIFO method. Provisions are made to reduce excess or obsolete inventories to their estimated net realizable values. Property, Plant and Equipment Property, plant and equipment are recorded at cost, net of accumulated depreciation and amortization. Improvements, betterments and replacements which extend the life of an asset are capitalized. Depreciation and amortization 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 depreciation, and the sales proceeds received. A gain or loss on an asset disposal is recognized in the period that the sale occurs. Leases Operating lease arrangements are comprised primarily of real estate and equipment agreements. The Company determines if an arrangement contains a lease at inception based on whether it conveys the right to control the use of an identified asset in exchange for consideration. Lease right-of-use assets (“ROU assets”) and associated lease liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Certain lease agreements may include one or more options to extend or terminate a lease. Lease terms are inclusive of these options if it is reasonably certain that the Company will exercise such options. ROU assets also include any initial direct costs and prepayments less lease incentives. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. Lease expense is recognized on a straight-line basis over the lease term. ROU assets and the corresponding operating lease liabilities are included in other assets and other liabilities in our consolidated balance sheets. Finance leases are included in property and equipment, other current liabilities, and other long-term liabilities in our consolidated balance sheets. 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. Management determined there was no impairment for the years ended December 31, 2023, 2022 and 2021. Goodwill and Indefinite-Lived Intangible Asset Goodwill reflects the excess of the consideration transferred, including the fair value of any contingent consideration over the assigned fair values of the identifiable net assets acquired. Goodwill is not amortized and is assigned at the reporting unit level and tested for impairment on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. 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 cannot determine if it is more likely than not that the fair value of a reporting unit is greater than its carrying value, a quantitative assessment is performed. The quantitative approach compares the estimated fair value of the reporting unit to its carrying amount, including goodwill. Impairment is indicated if the estimated fair value or the reporting unit is less than the carrying amount of the reporting unit, and an impairment charge is recognized for the differential. When determining the fair value of a reporting unit using the quantitative approach, we determine the fair value of the reporting unit using both a discounted cash flow (“DCF”) analysis and guideline publicly-traded companies (“GPC”) analysis to determine the fair value of the reporting unit. The Company has one indefinite-lived intangible asset for a Trade name it acquired as part of a past acquisition. The Company performs an annual impairment test on its Trade name indefinite-lived intangible asset, utilizing a qualitative or quantitative impairment analysis during the fourth quarter of each year. Investment in Equity Securities In 2021, the Company invested $12.0 million in the preferred stock of a private company. The investment is accounted for, in accordance with ASC 321 Investments — Equity Securities. Because the securities do not have a readily determined fair value, they are valued at cost, less any impairment. If the Company identifies an observable price change in an orderly transaction, the Company will measure the investment at fair value as of the date the observable transaction occurred. The equity investment is recorded in other assets on the consolidated balance sheets. No impairment has been recognized since the date of investment. Amortizable and Other Intangible Assets The Company amortizes identifiable finite lived intangible assets consisting of developed technology, customer relationships, contractual backlog and the STI trade name on a straight-line basis over the assets’ estimated useful lives. The basis of amortization approximates the pattern in which the assets are utilized, over their estimated useful lives. The Array Technologies trade name has been determined to have an indefinite life and, therefore, is not amortized but is subject to an annual impairment test or at any other time when impairment indicators exist. The Company did not recognize any impairment charges for the years ended December 31, 2023, 2022 and 2021. 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 offerings. Deferred offering costs were offset against the proceeds. Debt Discount and Issuance Costs Debt discount and issuance costs incurred to issue debt are deferred and amortized using the effective interest method as a component of interest expense over the life of the related debt agreement. Amortization expense of debt discount and deferred issuance costs was $10.6 million, $6.9 million and $15.0 million (including $9.6 million in write-offs in connection with unscheduled principal payoffs that occurred in February and August of 2021), for the years ended December 31, 2023, 2022 and 2021, respectively. Revenue Recognition In accordance with ASC 606, the Company recognizes revenues from the sale of solar tracking systems, parts, installation services, extended warranties on solar tracker system components and software licenses along with associated maintenance and support. 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 when, or as the performance obligation has been satisfied. In assessing the recognition of revenue, the Company also evaluates whether two or more contracts should be combined and accounted for as one contract and if the combined or single contract should be accounted for as multiple performance obligations which could change the amount of revenue and profit (loss) recorded in a period. Further, the Company assesses whether control of the product or services promised under the contract is transferred to the customer at a point in time or over time. Performance Obligations The Company’s contracts for specific solar tracker system projects with customers are predominantly accounted for as a single performance obligation, because the Company is integrating the solar tracking system components and related services as part of a single project. The Company’s performance creates and enhances an asset that the customer controls as the Company performs under the contract, which is principally as tracker system components are delivered to the designated project site. The Company sources the component parts from third party manufacturers, it obtains control and receives title of such parts before transferring them to the customer because the Company is responsible for fulfillment to its customer. The Company’s engineering services and professional services are interdependent with the component parts whereby the parts form an input into a combined output for which it is the principal, and the Company could redirect the parts before they are transferred to the customer if needed. The customer owns the work-in-process over the course of the project and the Company’s performance enhances a customer-controlled asset, resulting in the recognition of the performance obligation over time. In contracts with a single performance obligation, the Company’s obligation is satisfied over-time as control is transferred to the customer by measuring the progress toward complete satisfaction of the performance obligation using an input (i.e., the “cost-to-cost”) method. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The costs of materials and hardware components are recognized as incurred, which is typically upon delivery to the customer site or upon transfer of control while in transit. For contracts with customers that result in multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using its best estimate of the standalone selling price of each distinct good or service in the contract. These contracts include contracts for the sale of components, contracts with installation services, solar tracker systems sold with an extended warranty, and contracts that include the sale of software and maintenance. For all years presented, the transaction price associated with extended warranties and the sale of software and maintenance was not material. The Company uses the expected cost-plus margin approach to estimate the standalone selling price of each performance obligation. For contracts related to the sale of components as opposed to contracts to provide an integrated solar tracker project, the Company’s obligation to the customer is to deliver components that are used by the customer to create a tracker system and does not include engineering or other professional services or the obligation to provide such services in the future. Under these arrangements, each component is a distinct performance obligation, and often the components are delivered in batches at different points in time. The Company estimates the standalone selling price (“SSP”) of each performance obligation based on a cost-plus margin approach. Revenue allocated to a component is recognized at the point in time that control of the component transfers to the customer, which is usually upon delivery to the customer’s site. Contracts are often modified through change orders to account for changes in specifications or design, manner of performance, equipment, materials, scope of work, and/or the period of completion of the project. Although the Company evaluates each change order to determine whether such modification creates a separate performance obligation, the majority of change orders are for goods or services that are not distinct within the context of the original contract and, therefore, not treated as separate performance obligations but rather as a modification of the existing contract and performance obligation. Bill and Hold Arrangements In certain situations, the Company recognizes revenue under bill-and-hold arrangements with its customers. In all bill-and-hold arrangements, because the customers lack sufficient storage capacity to accept a large amount of material prior to the start of construction, they request that the Company keep the product in our custody. The material is bundled or palletized in the Company’s warehouses, identified separately as belonging to the respective customer and is ready for immediate transport to the customer project upon customer request. Additionally, title and risk of loss has passed to the customer and the Company does not have the ability to use the product or direct it to another customer. Contract Estimates Accounting for contracts utilizing the cost-to-cost measure of progress is based on various assumptions to project the outcome of future events that can exceed a year. These assumptions include the cost and availability of materials. The Company reviews and updates its contract-related estimates on an ongoing basis and recognizes adjustments for any project specific facts and circumstances that could impact the measurement of the extent of progress, such as the total costs to complete the contracts, under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. At contract inception, any variable consideration such as liquidated damages are estimated based on probability of occurrence and then re-evaluated for probability at the end of the quarterly period. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the total loss in the period it is identified. Contract Balances The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled accounts receivable for goods or services delivered but not invoiced, and deferred revenue (contract liabilities) on the consolidated balance sheets. The majority of the Company’s contract amounts are billed as work progresses in accordance with agreed-upon contractual terms, which generally coincide with the shipment of one or more phases of the project. Billing sometimes occurs subsequent to revenue recognition, resulting in unbilled accounts receivable. The changes in unbilled accounts receivable and the corresponding amounts recorded in revenue relate to fluctuations in the timing and volume of billings for the Company’s revenue recognized over-time. Practical Expedients and Exemptions The Company has elected to adopt certain practical expedients and exemptions as allowed under ASC 606, such as (i) recording sales commissions as incurred because the amortization period is less than one year, (ii) not adjusting for the effects of significant financing components when the contract term is less than one year, (iii) excluding collected sales tax amounts from the calculation of revenue and (iv) accounting for the costs of shipping and handling activities that are incurred after the customer obtains control of the product as fulfillment costs rather than a separate service provided to the customer for which consideration would need to be allocated. Warranty Obligations The Company offers a multi-year assurance type warranty for its products against manufacturer defects and does not contain service elements. For these assurance type warranties, a provision for estimated future costs related to warranty expense is recorded when they are probable and reasonably estimable, which is typically when products are delivered. 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. These estimates are re-evaluated on an ongoing basis using best-available information and revisions to estimates are made as necessary. Claims estimated to be payable in the following year are classified as current liabilities and those payable beyond one year are classified as long-term liabilities. Income Taxes The Company provides for income taxes based on the provisions of ASC Topic 740 Income Taxes (“ASC 740”), which, among other things, requires that recognition of deferred income taxes be measured by the provisions of enacted tax rates in effect at the date of the consolidated financial statements. A valuation allowance is provided to reduce deferred income tax assets if it is more likely than not that all, or some portion, of such deferred tax assets will not be recognized. Provision for estimated income taxes is based upon elements of income and expense reported in the consolidated statements of operations. The Company also files certain corporate state income tax returns. Generally, the Company is subject to examination by U.S. federal, state and non-U.S. income tax authorities. The current provision for income taxes represents actual or estimated amounts payable on tax return filings each year. Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying consolidated balance sheets, and for operating loss and tax credit carryforwards. The change in deferred tax assets and liabilities for the period measures the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws on deferred tax assets and liabilities are reflected as adjustments to the tax provision or benefit in the period of enactment. The Company determines whether uncertain tax positions are more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The Company recognizes interest and penalties related to unrecognized tax benefits within interest expense and other expenses, respectively, in the consolidated statements of operations. The Company does not have any uncertain tax positions. 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 underlying share price and a number of assumptions, including volatility, performance period, risk-free interest rate and expected dividends. The Company values equity awards with a market condition using a Monte Carlo simulation model. 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. Temporary Equity Equity instruments that are redeemable for cash or other assets are classified as temporary equity if the instrument is redeemable, at the option of the holder, at a fixed or determinable price on a fixed or determinable date or upon the occurrence of an event that is not solely within the control of the issuer. Redeemable equity instruments are initially carried at the fair value of the equity instrument at the issuance date, which is subsequently adjusted at each balance sheet date if the instrument is currently redeemable, or probable of becoming redeemable. The Series A Redeemable Perpetual Preferred Stock of the Company, par value $0.001 per share (the “Series A Shares”) issued in connection with the SPA as described in Note 12 – Redeemable Perpetual Preferred Stock are classified as temporary equity in the accompanying consolidated financial statements. The Company elected the accreted redemption value method under which it accretes changes in redemption value over the period from the date of issuance of the Series A Shares to the earliest costless redemption date (the fifth anniversary) using the effective interest method. Such adjustments are included in preferred undeclared dividends and accretion on Series A Shares on the Company’s consolidated statements of changes in redeemable perpetual preferred stock and stockholders’ equity (deficit) and treated similarly to a dividend on preferred stock in accordance with U.S. GAAP. Earnings per Share Basic earnings per share (“EPS”), is computed by dividing net income available to common shareholders 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 stock options, unvested restricted stock, or convertible debt, were exercised and converted into shares. The convertible debt is not currently convertible. Diluted EPS is computed by dividing net income available to common shareholders 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. Credit Concentration Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and accounts receivable. The Company has no significant off balance sheet concentrations of credit risk. The Company maintains its cash with financial institutions that are believed to be of high credit quality and has not experienced any material losses relating to cash balances. Our customer base consists primarily of large solar developers, independent power producers, utilities and EPCs. We do not require collateral on our accounts receivable. At December 31, 2023, the Company’s largest customer and five largest customers accounted for 2.7% and 29.6%, respectively, of total accounts receivable. At December 31, 2022, the Company’s largest and five largest customers constituted 7.9% and 23.4% of trade accounts receivable, respectively. During the year ended December 31, 2023, one customer accounted for 13.4% of total revenue. During the year ended December 31, 2022, two customers accounted for 11.8% and 10.6%, respectively, of total revenue. During the year ended December 31, 2021, two customers accounted for 12.6% and 10.2%, respectively, of total revenue. Further, our accounts receivable are from companies within the solar industry and, as such, we are exposed to normal industry credit risk. We continually evaluate our reserves for potential credit losses and establish reserves for such losses. 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, accounts receivable, and accounts payable approximate their carrying values due to their short maturities. The carrying value of the Company’s notes payable approximate their fair values, as they are based on current market rates at which the Company could borrow funds with similar terms. The Company follows the provisions of ASC 820 Fair Value Measurement for nonfinancial assets and liabilities measured at fair value on a non-recurring basis. As it relates to the Company, this applies to certain nonfinancial assets and liabilities acquired in business combinations and measurement of goodwill impairment and non-amortizable intangibles and is thereby measured at fair value, which was determined by the Company with the assistance of third-party valuation specialists. Recent Accounting Pronouncements In March 2023, the Company amended an existing debt agreement to replace the London Interbank Offered Rate (“LIBOR”) interest rate provisions with interest rate provisions based on a forward-looking term rate based on the secured overnight funding rate (“SOFR”) (see Note 11 – Debt). There were no other changes to the agreement. There was no significant impact to the Company’s consolidated financial statements. In November 2023, the Financial Accounting Standards Board (the “FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments in this ASU will require public entities to disclose significant segment expenses and other segment items and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. Public entities with a single reportable segment will also be required to provide the new disclosures and all the disclosures required under ASC 280. The guidance is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments in this ASU should be applied retrospectively to all periods presented unless it is impracticable. The Company is currently assessing the impact of the guidance on its financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. The standard will become effective for the Company’s fiscal year ended December 31, 2025, with early adoption permitted. The Company is currently assessing the impact of the new guidance on the its consolidated financial statements.

Beginning in the third quarter of 2023, the Company reclassified amounts recorded for amortization of certain acquired intangible assets in prior presentations from Total operating expenses under the caption "Depreciation and amortization" to Total cost of revenue under the caption "Amortization of developed technology" in the consolidated statements of operations. The Company believes this presentation enhances the comparability of the Company’s financial statements to industry peers. This reclassification resulted in $14.6 million recorded to Amortization of developed technology within Total cost of revenue and a $14.6 million decrease to Depreciation and amortization within Total operating expenses during the year ended December 31, 2022. This reclassification did not impact the Company’s operating income (loss), net income (loss) or earnings (loss) per share for any current or historical periods. These reclassifications also did not impact the consolidated balance sheets or consolidated statements of cash flows for the dates and annual periods presented.

Revenue in 2023, excludes a Brazil value-added tax benefit, Imposto sobre Circulação de Mercadorias e Servicos (“ICMS”), that has been reclassified and included in cost of revenues in the current year. For the year ended December 31, 2023, the Brazil ICMS value-added tax benefit was $23.2 million. For the year ended December 31, 2022, an ICMS benefit of $12.3 million was included in revenues.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Although management believes its estimates are reasonable, actual results could differ from those estimates.

The ongoing Russian-Ukraine conflict has reduced the availability of material that can be sourced in Europe and, as a result, increased logistics costs for the procurement of certain inputs and materials used in our products. We do not know the ultimate severity or duration of the conflict, but we continue to monitor the situation and evaluate our procurement strategy and supply chain as to reduce any negative impact on our business, financial condition and results of operations.

Houthi rebels in Yemen have significantly stepped-up attacks against commercial vessels in the Bab-el-Mandeb strait between the Arabian peninsula and the Horn of Africa since late November of 2023, which has led to many shipping companies pausing shipments through the Suez Canal and the Red Sea. Many of these shipments are being redirected around the Cape of Good Hope in South Africa, adding between 3,000 – 3,500 nautical miles to routes connecting Europe with Asia. As an additional result of the reroute, certain ports could see crowding and delays in unloading shipments. We do not yet know the duration of these disruptions or the severity of their impact on our operations, but we continue to monitor the situation and evaluate our procurement strategy and supply chain to reduce any negative impact on our business, financial condition and results of operations.

On August 16, 2022, the Inflation Reduction Act of 2022 (“IRA”) was enacted into law, which includes numerous green energy credits. The 45X Advanced Manufacturing Production Tax Credit (“45X Credit”) was established as part of the IRA. The 45X Credit is a per-unit tax credit that is earned over time for each clean energy component domestically produced and sold by a manufacturer. The Company has, and will continue to, enter into arrangements with torque tube manufacturing vendors that produce 45X Credit eligible parts, in which the vendors agree to share a portion of the benefit received related to Array purchases, in the form of “Vendor Rebates”.

The Company accounts for these Vendor Rebates as a reduction of the purchase prices of the vendors’ products and therefore a reduction of inventory until the inventory is sold, at which time the Company recognizes such rebates as a reduction of cost of revenues on the consolidated statements of operations. Rebates related to purchases that were made prior to the execution of the agreements are deferred and recognized as a reduction of the prices of future purchases. During the three months ended December 31, 2023, the Company had accumulated a total of $49.9 million in Vendor Rebates from current year activity, of which $48.4 million was outstanding and included in Prepaid expenses and other, and $40.6 million of deferred consideration was included in Other current liabilities, on the consolidated balance sheet as of December 31, 2023.

Our foreign subsidiaries have functional currencies that are different than our reporting currency. When translating balances from the functional currency to the reporting currency, assets and liabilities are translated into U.S. dollars at period end exchange rates, retained earnings is translated at historical rates, and income, expenses, and cash flow items are translated at average exchange rates prevailing during the period. Translation adjustments for these subsidiaries are accumulated within accumulated other comprehensive income. In situations when a foreign subsidiary has a local currency that is different than the functional currency, monetary assets and liabilities are translated into the functional currency at the period end exchange rates, and non-monetary assets and the related income statement effects are translated into the functional currency using historical rates. Gains and losses that result from remeasurement from a local currency to the functional currency are included in earnings.

The Company’s accounts receivable are due primarily from solar contractors across the U.S. and internationally. Credit is extended in the normal course of business based on evaluation of a customer’s financial condition and, generally, collateral is not required. Trade receivables consist of uncollateralized customer obligations due under normal trade terms requiring payment within 30 to 60 days of the invoice date. Management regularly reviews outstanding accounts receivable and provides for estimated credit losses through an estimate of expected credit losses valuation account. The Company adopted Accounting Standards Updated (“ASU”) No. 2016-13, Financial Instruments - Credit Losses, on January 1, 2021, which revised the methodology for measuring credit losses on financial instruments including trade accounts receivable and the timing of when such losses are recorded. The Company adopted ASU 2016-13 using a modified retrospective approach with a cumulative effect adjustment to the opening balance of retained earnings, which had no impact on the consolidated financial statements. The allowance for credit losses is a valuation account that is deducted from a financial asset’s amortized cost to present the net amount we expect to collect from the asset. We estimate allowances for credit losses using relevant available information from both internal and external sources. We monitor the estimated credit losses associated with our trade accounts receivable and unbilled accounts receivable based primarily on our collection history and the delinquency status of amounts owed to us, which we determine based on the aging of such receivables. In evaluating the level of established reserves, management makes judgments regarding the customers’ ability to make required payments, economic events, and other factors. As the financial conditions of these customers change, circumstances develop, or additional

Unbilled receivables represent temporary timing differences between shipments made and billing milestones achieved and are recorded in the accounts receivable balances. Such amounts have not been billed due to pending commercial criteria such as billing on a specified date of the month or upon completion of mega-watt deliveries. Unbilled receivables are invoiced once the underlying commercial criteria have been met and we expect payment within 30 to 60 days.

Operating lease arrangements are comprised primarily of real estate and equipment agreements. The Company determines if an arrangement contains a lease at inception based on whether it conveys the right to control the use of an identified asset in exchange for consideration. Lease right-of-use assets (“ROU assets”) and associated lease liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Certain lease agreements may include one or more options to extend or terminate a lease. Lease terms are inclusive of these options if it is reasonably certain that the Company will exercise such options.

ROU assets also include any initial direct costs and prepayments less lease incentives. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. Lease expense is recognized on a straight-line basis over the lease term.

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. Management determined there was no impairment for the years ended December 31, 2023, 2022 and 2021.

Goodwill reflects the excess of the consideration transferred, including the fair value of any contingent consideration over the assigned fair values of the identifiable net assets acquired. Goodwill is not amortized and is assigned at the reporting unit level and tested for impairment on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. 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 cannot determine if it is more likely than not that the fair value of a reporting unit is greater than its carrying value, a quantitative assessment is performed. The quantitative approach compares the estimated fair value of the reporting unit to its carrying amount, including goodwill. Impairment is indicated if the estimated fair value or the reporting unit is less than the carrying amount of the reporting unit, and an impairment charge is recognized for the differential.

In 2021, the Company invested $12.0 million in the preferred stock of a private company. The investment is accounted for, in accordance with ASC 321 Investments — Equity Securities. Because the securities do not have a readily determined fair value, they are valued at cost, less any impairment. If the Company identifies an observable price change in an orderly transaction, the Company will measure the investment at fair value as of the date the observable transaction occurred. The equity investment is recorded in other assets on the consolidated balance sheets. No impairment has been recognized since the date of investment.

Debt discount and issuance costs incurred to issue debt are deferred and amortized using the effective interest method as a component of interest expense over the life of the related debt agreement. Amortization expense of debt discount and deferred issuance costs was $10.6 million, $6.9 million and $15.0 million (including $9.6 million in write-offs in connection with unscheduled principal payoffs that occurred in February and August of 2021), for the years ended December 31, 2023, 2022 and 2021, respectively.

In accordance with ASC 606, the Company recognizes revenues from the sale of solar tracking systems, parts, installation services, extended warranties on solar tracker system components and software licenses along with associated maintenance and support. 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 when, or as the performance obligation has been satisfied.

In assessing the recognition of revenue, the Company also evaluates whether two or more contracts should be combined and accounted for as one contract and if the combined or single contract should be accounted for as multiple performance obligations which could change the amount of revenue and profit (loss) recorded in a period. Further, the Company assesses whether control of the product or services promised under the contract is transferred to the customer at a point in time or over time.

The Company’s contracts for specific solar tracker system projects with customers are predominantly accounted for as a single performance obligation, because the Company is integrating the solar tracking system components and related services as part of a single project. The Company’s performance creates and enhances an asset that the customer controls as the Company performs under the contract, which is principally as tracker system components are delivered to the designated project site. The Company sources the component parts from third party manufacturers, it obtains control and receives title of such parts before transferring them to the customer because the Company is responsible for fulfillment to its customer. The Company’s engineering services and professional services are interdependent with the component parts whereby the parts form an input into a combined output for which it is the principal, and the Company could redirect the parts before they are transferred to the customer if needed. The customer owns the work-in-process over the course of the project and the Company’s performance enhances a customer-controlled asset, resulting in the recognition of the performance obligation over time.

In contracts with a single performance obligation, the Company’s obligation is satisfied over-time as control is transferred to the customer by measuring the progress toward complete satisfaction of the performance obligation using an input (i.e., the “cost-to-cost”) method. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The costs of materials and hardware components are recognized as incurred, which is typically upon delivery to the customer site or upon transfer of control while in transit.

For contracts with customers that result in multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using its best estimate of the standalone selling price of each distinct good or service in the contract. These contracts include contracts for the sale of components, contracts with installation services, solar tracker systems sold with an extended warranty, and contracts that include the sale of software and maintenance. For all years presented, the transaction price associated with extended warranties and the sale of software and maintenance was not material. The Company uses the expected cost-plus margin approach to estimate the standalone selling price of each performance obligation.

For contracts related to the sale of components as opposed to contracts to provide an integrated solar tracker project, the Company’s obligation to the customer is to deliver components that are used by the customer to create a tracker system and does not include engineering or other professional services or the obligation to provide such services in the future. Under these arrangements, each component is a distinct performance obligation, and often the components are delivered in batches at different points in time. The Company estimates the standalone selling price (“SSP”) of each performance obligation based on a cost-plus margin approach. Revenue allocated to a component is recognized at the point in time that control of the component transfers to the customer, which is usually upon delivery to the customer’s site.

Contracts are often modified through change orders to account for changes in specifications or design, manner of performance, equipment, materials, scope of work, and/or the period of completion of the project. Although the Company evaluates each change order to determine whether such modification creates a separate performance obligation, the majority of change orders are for goods or services that are not distinct within the context of the original contract and, therefore, not treated as separate performance obligations but rather as a modification of the existing contract and performance obligation.

In certain situations, the Company recognizes revenue under bill-and-hold arrangements with its customers. In all bill-and-hold arrangements, because the customers lack sufficient storage capacity to accept a large amount of material prior to the start of construction, they request that the Company keep the product in our custody. The material is bundled or palletized in the Company’s warehouses, identified separately as belonging to the respective customer and is ready for immediate transport to the customer project upon customer request. Additionally, title and risk of loss has passed to the customer and the Company does not have the ability to use the product or direct it to another customer.

availability of materials. The Company reviews and updates its contract-related estimates on an ongoing basis and recognizes adjustments for any project specific facts and circumstances that could impact the measurement of the extent of progress, such as the total costs to complete the contracts, under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. At contract inception, any variable consideration such as liquidated damages are estimated based on probability of occurrence and then re-evaluated for probability at the end of the quarterly period. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the total loss in the period it is identified.

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled accounts receivable for goods or services delivered but not invoiced, and deferred revenue (contract liabilities) on the consolidated balance sheets. The majority of the Company’s contract amounts are billed as work progresses in accordance with agreed-upon contractual terms, which generally coincide with the shipment of one or more phases of the project. Billing sometimes occurs subsequent to revenue recognition, resulting in unbilled accounts receivable. The changes in unbilled accounts receivable and the corresponding amounts recorded in revenue relate to fluctuations in the timing and volume of billings for the Company’s revenue recognized over-time.

The Company has elected to adopt certain practical expedients and exemptions as allowed under ASC 606, such as (i) recording sales commissions as incurred because the amortization period is less than one year, (ii) not adjusting for the effects of significant financing components when the contract term is less than one year, (iii) excluding collected sales tax amounts from the calculation of revenue and (iv) accounting for the costs of shipping and handling activities that are incurred after the customer obtains control of the product as fulfillment costs rather than a separate service provided to the customer for which consideration would need to be allocated.

The Company offers a multi-year assurance type warranty for its products against manufacturer defects and does not contain service elements. For these assurance type warranties, a provision for estimated future costs related to warranty expense is recorded when they are probable and reasonably estimable, which is typically when products are delivered. 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. These estimates are re-evaluated on an ongoing basis using best-available information and revisions to estimates are made as necessary. Claims estimated to be payable in the following year are classified as current liabilities and those payable beyond one year are classified as long-term liabilities.

The Company provides for income taxes based on the provisions of ASC Topic 740 Income Taxes (“ASC 740”), which, among other things, requires that recognition of deferred income taxes be measured by the provisions of enacted tax rates in effect at the date of the consolidated financial statements. A valuation allowance is provided to reduce deferred income tax assets if it is more likely than not that all, or some portion,

of such deferred tax assets will not be recognized. Provision for estimated income taxes is based upon elements of income and expense reported in the consolidated statements of operations. The Company also files certain corporate state income tax returns. Generally, the Company is subject to examination by U.S. federal, state and non-U.S. income tax authorities. The current provision for income taxes represents actual or estimated amounts payable on tax return filings each year. Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying consolidated balance sheets, and for operating loss and tax credit carryforwards. The change in deferred tax assets and liabilities for the period measures the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws on deferred tax assets and liabilities are reflected as adjustments to the tax provision or benefit in the period of enactment.

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 underlying share price and a number of assumptions, including volatility, performance period, risk-free interest rate and expected dividends. The Company values equity awards with a market condition using a Monte Carlo simulation model. 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.

Equity instruments that are redeemable for cash or other assets are classified as temporary equity if the instrument is redeemable, at the option of the holder, at a fixed or determinable price on a fixed or determinable date or upon the occurrence of an event that is not solely within the control of the issuer. Redeemable equity instruments are initially carried at the fair value of the equity instrument at the issuance date, which is subsequently adjusted at each balance sheet date if the instrument is currently redeemable, or probable of becoming redeemable. The Series A Redeemable Perpetual Preferred Stock of the Company, par value $0.001 per share (the “Series A Shares”) issued in connection with the SPA as described in Note 12 – Redeemable Perpetual Preferred Stock are classified as temporary equity in the accompanying consolidated financial statements. The Company elected the accreted redemption value method under which it accretes changes in redemption value over the period from the date of issuance of the Series A Shares to the earliest costless redemption date (the fifth anniversary) using the effective interest method. Such adjustments are included in preferred undeclared dividends and accretion on Series A Shares on the Company’s consolidated statements of changes in redeemable perpetual preferred stock and stockholders’ equity (deficit) and treated similarly to a dividend on preferred stock in accordance with U.S. GAAP.

dilution that could occur if securities or other contracts to issue shares, such as stock options, unvested restricted stock, or convertible debt, were exercised and converted into shares. The convertible debt is not currently convertible. Diluted EPS is computed by dividing net income available to common shareholders 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.

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and accounts receivable. The Company has no significant off balance sheet concentrations of credit risk. The Company maintains its cash with financial institutions that are believed to be of high credit quality and has not experienced any material losses relating to cash balances.

The Company follows the provisions of ASC 820 Fair Value Measurement for nonfinancial assets and liabilities measured at fair value on a non-recurring basis. As it relates to the Company, this applies to certain nonfinancial assets and liabilities acquired in business combinations and measurement of goodwill impairment and non-amortizable intangibles and is thereby measured at fair value, which was determined by the Company with the assistance of third-party valuation specialists.

In March 2023, the Company amended an existing debt agreement to replace the London Interbank Offered Rate (“LIBOR”) interest rate provisions with interest rate provisions based on a forward-looking term rate based on the secured overnight funding rate (“SOFR”) (see Note 11 – Debt). There were no other changes to the agreement. There was no significant impact to the Company’s consolidated financial statements.

In November 2023, the Financial Accounting Standards Board (the “FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments in this ASU will require public entities to disclose significant segment expenses and other segment items and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. Public entities with a single reportable segment will also be required to provide the new disclosures and all the disclosures required under ASC 280. The guidance is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments in this ASU should be applied retrospectively to all periods presented unless it is impracticable. The Company is currently assessing the impact of the guidance on its financial statements.
