Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Accounting and Presentation The accompanying unaudited condensed consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The unaudited interim financial statements have been prepared on the same basis as the audited annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of results for the interim periods reported. The results for the three and six months ended June 30, 2022 are not necessarily indicative of results to be expected for the year ending December 31, 2022 or any other interim periods, or any future year or period. The balance sheet as of December 31, 2021 included herein was derived from the audited financial statements as of that date. Certain disclosures have been condensed or omitted from the interim financial statements. These financial statements should be read in conjunction with the Company’s audited financial statements included in the Company’s Annual Report on Form 10-K filed with the SEC on April 6, 2022, as amended by the Form 10-K/A filed with the SEC on April 6, 2022 (the “2021 Annual Report”). Principles of Consolidation The condensed 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 condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates include evaluation for any impairment of goodwill, impairment of long-lived assets, fair value of contingent consideration, Series A Redeemable Perpetual Preferred Stock and the related future tranche, allowance for credit losses, reserve for excess or obsolete inventories, valuation of deferred tax assets and warranty reserve. Actual results may differ from previously estimated amounts, and such differences may be material to the condensed consolidated financial statements; however, management believes that these estimates and assumptions provide a reasonable basis for the fair presentation of the consolidated financial statements. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the period they occur. Impact of COVID-19 Pandemic In December 2019, a novel strain of coronavirus, SARS-CoV-2, which causes coronavirus disease 2019 (“COVID-19”), surfaced in Wuhan, China. Since then, COVID-19 has spread to multiple countries, including the United States. On March 11, 2020, the World Health Organization declared COVID-19 a pandemic. Due to economic conditions, the Company’s industry has seen rapid commodity price increases and strained logistics, causing the Company to experience decreased margins and thus decreased cash from operations which has adversely impacted the Company’s business. In addition, due to global tightening of supply chain and strained logistics issues the Company has experienced an increase in unbilled revenues and in some instances incurred liquidated damages. The Company has taken, and continues to take, mitigating steps to overcome the economic challenges and, therefore, believes the impact to be temporary, but cannot be certain the timing of when it will achieve better margins. The extent to which the COVID-19 pandemic and recent supply chain constraints and price increases may further impact the Company’s business, results of operations, financial condition and cash flows will depend on future developments, which are highly uncertain and cannot be predicted with confidence. The Company believes it has sufficient liquidity and financing options available and expects to have sufficient liquidity to operate for the next 12 months. The Company expects to use cash generated from operations and if needed, can access funds from the Revolving Credit Facility (as defined below). The Company also has $100 million in delayed draw ability under the Series A Redeemable Perpetual Preferred Stock (as defined below) future draw commitment; however, such a draw would increase the Company’s dividend obligations and outstanding common stock and failure to draw the delayed commitments will result in interest expense payable by the company. See Note 13 – Redeemable Perpetual Preferred. The Revolving Credit Facility has $96.7 million of availability; however, the Company may have limited ability to draw on the funds due to existing debt covenants. 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 are continuously monitoring the situation and evaluating our procurement strategy and supply chain as to reduce any negative impact on our business, financial condition and results of operations. Inflation The Company could see an impact from inflationary pressures. Inflation has continued to accelerate in the wake of Russia’s invasion of Ukraine, driving up energy prices, freight premiums, and other operating costs. Interest rates, notably mature market government bond yields, remain low by historical standards but are rising as central banks around the world tighten monetary policy in response to inflation pressures, while government deficits and debt remain at high levels in many major markets. The eventual implications of higher government deficits and debt, tighter monetary policy, and potentially higher long-term interest rates may drive a higher cost of capital during our forecast period. Business Combinations The Company accounts for its business acquisitions under the acquisition method of accounting in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 805 Business Combinations (“ASC 805”). The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, asset lives, and market multiples, amongst other items. Foreign Currency Translation For non-U.S. subsidiaries that operate in a local currency environment, assets and liabilities are translated into the U.S. dollar 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 accumulated other comprehensive income in equity. 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. Recent Accounting Pronouncements Adopted In October 2021, the FASB issued 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 the company acquiring contract assets and contract liabilities obtained in a business combination to recognize and measure them in accordance with 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. A review of the deferred revenue of the acquiree of $20.3 million was reviewed for consistency in application with the Company’s policies and U.S. GAAP and the contract liability balance was carried over at its carrying value.
