Accounting Policies [Abstract]
Basis of Accounting and Presentation	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	Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation.
Recently Accounting Pronouncements	Recent Accounting PronouncementsIn October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). ASU 2021-08 requires contract assets and contract liabilities obtained in a business combination to be recognized and measured in accordance with Accounting Standards Codification (“ASC”) Topic 606 Revenue from Contracts with Customers (“ASC 606”). At the acquisition date, the company acquiring the business should record related revenue, as if it had originated the contract. Before the recent update, such amounts were recognized by the acquiring company at fair value. The amendments in this update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including in interim periods, for any financial statements that have not yet been issued. The Company early adopted ASU 2021-08 as of January 1, 2022. See Note 3 – Acquisition of STI for further information and disclosures related to the STI Acquisition. The standard was applied to the acquisition accounting for STI.
Principles of Consolidation	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	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 COVID-19 Pandemic, Impact of the Ongoing Conflict in Ukraine and Inflation	Impact of COVID-19 Pandemic We continue to closely monitor the ongoing impact of the COVID-19 pandemic in all the locations where we operate. At this time, the extent to which the pandemic may affect our business, operations and plans, including the resulting impact on our expenditures and capital needs, remains uncertain and is subject to change, but overall the pandemic appears to be having a lessening impact on our business and the markets in which we operate. On January 31, 2023, the Biden administration announced its plan to let the coronavirus public health emergency expire in May 2023. Impact of the Ongoing Conflict in Ukraine The ongoing conflict in Ukraine 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 ultimate severity or duration of the conflict in Ukraine, 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. Inflation Inflationary pressures, while somewhat moderating recently, are expected to persist, at least in the near-term, and may continue to negatively impact our results of operation. 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.
Foreign Currency Translation	Foreign Currency Translation For non-U.S. subsidiaries that operate in a local currency environment, assets and liabilities are translated into U.S. dollars at period end exchange rates. Income, expense and cash flow items are translated at average exchange rates prevailing during the period. Translation adjustments for these subsidiaries are accumulated as a separate component of net parent investment. For non-U.S. subsidiaries that use a U.S. dollar functional currency, local currency inventories and property, plant and equipment are translated into U.S. dollars at rates prevailing when acquired, and all other assets and liabilities are translated at period end exchange rates. Inventories charged to cost of sales and depreciation are remeasured at historical rates, and all other income and expense items are translated at average exchange rates prevailing during the period. Gains and losses which result from remeasurement are included in earnings.
Cash and Cash Equivalents	Cash and Cash EquivalentsThe 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. At December 31, 2022 all cash balances were deposited with banks, and we had no cash equivalents.
Accounts Receivable	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 30-60 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 ASU No. 2016-13, Financial Instruments - Credit Losses, (“ASU 2016-13”) 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 Inventories consist of raw materials and finished goods and are stated at the lower of cost or estimated net realizable value using primarily the weighted average method and some valued using 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 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	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	Impairment of Long-Lived AssetsWhen 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.
Goodwill	GoodwillGoodwill 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 determines that 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 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.
Investment in Equity Securities	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, at its cost less any impairment. 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	Amortizable and Other Intangible AssetsThe 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.
Indefinite-Lived Intangible Assets	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.
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 offerings. Deferred offering costs were offset against the proceeds.
Debt Discount and Financing Costs	Debt Discount and Issuance CostsDebt 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.
Revenue Recognition	Revenue Recognition In accordance with ASC 606, the Company recognizes revenues from the sale of solar tracking systems and parts and 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. Performance Obligations The majority of the Company’s contracts with customers are accounted for as one performance obligation, because the Company is integrating the solar tracking system components and related services as part of a single project. Certain contracts associated with customers using the federal investment tax credit (“ITC”) for solar energy projects and other standalone tracker component sales are accounted for as multiple performance obligations because the delivery of the components and other services specified in the contract do not represent a single integrated project. 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. For contracts with 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. The Company uses the expected cost-plus margin approach to estimate the standalone selling price of each performance obligation. Revenue recognized for the Company’s federal investment tax credit (“ITC”) related contracts and standalone system component is recorded at a point in time and recognized when obligations under the terms of the contract with our customer are satisfied. Generally, this occurs with the transfer of control of the asset, which is typically upon delivery to the customer in line with shipping terms. Any losses incurred on point-in-time projects are recognized as the goods are delivered. In certain situations, the Company recognizes revenue under a bill-and-hold arrangement with its customers. In arrangements related to the Federal Solar ITC, the customers purchase material prior to the start of construction of a solar project in order to meet the Five Percent Safe Harbor test to qualify for the Federal Solar ITC. 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. 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. 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. We account for shipping and handling activities related to contracts with customers as costs to fulfill our promise to transfer the associated products. Accordingly, we record amounts billed for shipping and handling costs as a component of revenue and classify such costs as a component of cost of revenue. 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. Contract Balances The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled accounts receivable for goods 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.
Warranty Obligations	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	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. Adjustments for penalties and interest, if any, are also reflected in the current year tax provision or benefit. 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. No material interest or penalties were incurred in 2022.
Equity-Based Compensation	Equity-Based CompensationThe 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	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 Securities Purchase Agreement as described in Note 11 – 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	Earnings per ShareBasic 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	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.
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, accounts receivable, and accounts payable approximate their carrying values due to their short maturities. The carrying value of the Company’s notes payable, capped call, and related party loans approximates 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 valuations.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2022

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

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

Recently Accounting Pronouncements

Recent Accounting PronouncementsIn October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). ASU 2021-08 requires contract assets and contract liabilities obtained in a business combination to be recognized and measured in accordance with Accounting Standards Codification (“ASC”) Topic 606 Revenue from Contracts with Customers (“ASC 606”). At the acquisition date, the company acquiring the business should record related revenue, as if it had originated the contract. Before the recent update, such amounts were recognized by the acquiring company at fair value. The amendments in this update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including in interim periods, for any financial statements that have not yet been issued. The Company early adopted ASU 2021-08 as of January 1, 2022. See Note 3 – Acquisition of STI for further information and disclosures related to the STI Acquisition. The standard was applied to the acquisition accounting for STI.

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 COVID-19 Pandemic, Impact of the Ongoing Conflict in Ukraine and Inflation

Impact of COVID-19 Pandemic

We continue to closely monitor the ongoing impact of the COVID-19 pandemic in all the locations where we operate. At this time, the extent to which the pandemic may affect our business, operations and plans, including the resulting impact on our expenditures and capital needs, remains uncertain and is subject to change, but overall the pandemic appears to be having a lessening impact on our business and the markets in which we operate. On January 31, 2023, the Biden administration announced its plan to let the coronavirus public health emergency expire in May 2023.

Impact of the Ongoing Conflict in Ukraine

The ongoing conflict in Ukraine 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 ultimate severity or duration of the conflict in Ukraine, 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.

Inflation

Inflationary pressures, while somewhat moderating recently, are expected to persist, at least in the near-term, and may continue to negatively impact our results of operation. 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.

Foreign Currency Translation

For non-U.S. subsidiaries that operate in a local currency environment, assets and liabilities are translated into U.S. dollars at period end exchange rates. Income, expense and cash flow items are translated at average exchange rates prevailing during the period. Translation adjustments for these subsidiaries are accumulated as a separate component of net parent investment. For non-U.S. subsidiaries that use a U.S. dollar functional currency, local currency inventories and property, plant and equipment are translated into U.S. dollars at rates prevailing when acquired, and all other assets and liabilities are translated at period end exchange rates. Inventories charged to cost of sales and depreciation are remeasured at historical rates, and all other income and expense items are translated at average exchange rates prevailing during the period. Gains and losses which result from remeasurement are included in earnings.

Cash and Cash Equivalents

Cash and Cash EquivalentsThe 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. At December 31, 2022 all cash balances were deposited with banks, and we had no cash equivalents.

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 30-60 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 ASU No. 2016-13, Financial Instruments - Credit Losses, (“ASU 2016-13”) 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 weighted average method and some valued using 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

Impairment of Long-Lived AssetsWhen 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.

Goodwill

GoodwillGoodwill 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 determines that 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 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.

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, at its cost less any impairment. 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

Amortizable and Other Intangible AssetsThe 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.

Indefinite-Lived Intangible Assets

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.

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 Financing Costs

Debt Discount and Issuance CostsDebt 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.

Revenue Recognition

In accordance with ASC 606, the Company recognizes revenues from the sale of solar tracking systems and parts and 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.

Performance Obligations

The majority of the Company’s contracts with customers are accounted for as one performance obligation, because the Company is integrating the solar tracking system components and related services as part of a single project. Certain contracts associated with customers using the federal investment tax credit (“ITC”) for solar energy projects and other standalone tracker component sales are accounted for as multiple performance obligations because the delivery of the components and other services specified in the contract do not represent a single integrated project.

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.

For contracts with 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. The Company uses the expected cost-plus margin approach to estimate the standalone selling price of each performance obligation.

Revenue recognized for the Company’s federal investment tax credit (“ITC”) related contracts and standalone system component is recorded at a point in time and recognized when obligations under the terms of the contract with our customer are satisfied. Generally, this occurs with the transfer of control of the asset, which is typically upon delivery to the customer in line with shipping terms. Any losses incurred on point-in-time projects are recognized as the goods are delivered.

In certain situations, the Company recognizes revenue under a bill-and-hold arrangement with its customers. In arrangements related to the Federal Solar ITC, the customers purchase material prior to the start of construction of a solar project in order to meet the Five Percent Safe Harbor test to qualify for the Federal Solar ITC. 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.

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.

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.

We account for shipping and handling activities related to contracts with customers as costs to fulfill our promise to transfer the associated products. Accordingly, we record amounts billed for shipping and handling costs as a component of revenue and classify such costs as a component of cost of revenue.

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.

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled accounts receivable for goods 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.

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. Adjustments for penalties and interest, if any, are also reflected in the current year tax provision or benefit.

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. No material interest or penalties were incurred in 2022.

Equity-Based Compensation

Equity-Based CompensationThe 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 Securities Purchase Agreement as described in Note 11 – 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

Earnings per ShareBasic 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.

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, capped call, and related party loans approximates 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 valuations.
