Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Nature of Operations and Basis of Presentation | Nature of Operations and Basis of Presentation – Amtech Systems, Inc. (the “Company,” “Amtech,” “we,” “our” or “us”) is a leading, global manufacturer of capital equipment, including thermal processing and wafer polishing, and related consumables used in fabricating semiconductor devices, such as silicon carbide (“SiC”) and silicon power devices, analog and discrete devices, electronic assemblies and light-emitting diodes (“LEDs”). We sell these products to semiconductor device and module manufacturers worldwide, particularly in Asia, North America and Europe. We serve niche markets in industries that are experiencing technological advances, and which historically have been very cyclical. Therefore, future profitability and growth depend on our ability to develop or acquire and market profitable new products and on our ability to adapt to cyclical trends. The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”), and consequently do not include all disclosures normally required by accounting principles generally accepted in the United States of America. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements contain all adjustments necessary, all of which are of a normal and recurring nature, to present fairly our financial position, results of operations and cash flows. Certain information and note disclosures normally included in financial statements have been condensed or omitted pursuant to the rules and regulations of the SEC. The condensed consolidated balance sheet at September 30, 2021, has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2021. Our fiscal year is from October 1 to September 30. Unless otherwise stated, references to particular years, quarters, months or periods refer to our fiscal years ending or ended September 30, and the associated quarters, months, and periods of those fiscal years. The consolidated results of operations for the three months ended December 31, 2021, are not necessarily indicative of the results to be expected for the full fiscal year. In March 2020, the outbreak of COVID-19 was recognized as a pandemic by the World Health Organization, and the outbreak became increasingly widespread, including in all of the markets in which we operate. We continue to monitor the impact of COVID-19 on all aspects of our business. We are a company operating in a critical infrastructure industry, as defined by the U.S. Department of Homeland Security. Consistent with federal guidelines and with foreign government, state and local orders to date, we have continued to operate across our footprint throughout the COVID-19 pandemic. Following the onset of COVID-19 and its negative effects on our business, most prominently reflected in our second, third and fourth quarter fiscal 2020 results, global economic conditions improved during fiscal 2021, resulting in increased demand for our products and services, which led to our earnings for fiscal 2021 substantially exceeding our fiscal 2020 results. There remain many unknowns and we continue to monitor the expected trends and related demand for our products and services and have and will continue to adjust our operations accordingly.
Principles of Consolidation | Principles of Consolidation – The consolidated financial statements include the accounts of the Company and our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates | Use of Estimates – The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Contract Liabilities | Contract Liabilities – Contract liabilities are reflected in current liabilities on the Condensed Consolidated Balance Sheets as all performance obligations are expected to be satisfied within the next 12 months. Contract liabilities include customer deposits and deferred profit, if any. Contract liabilities relate to payments invoiced or received in advance of completion of performance obligations under a contract. Contract liabilities are recognized as revenue upon the fulfillment of performance obligations. Contract liabilities consist of customer deposits as of December 31, 2021 and September 30, 2021. Of the $1.6 million contract liabilities recorded at September 30, 2021, $1.2 million was recorded as revenue for the three months ended December 31, 2021.
Shipping Expense | Shipping Expense – Shipping and handling fees associated with inbound and outbound freight are expensed as incurred and included in selling, general and administrative expenses. Shipping expense was $1.2 million and $0.1 million for the three months ended December 31, 2021 and 2020, respectively.
Debt | Debt – The recorded amounts of these financial instruments, including long-term debt and current maturities of long-term debt, have an interest rate of 4.11% and are due in September 2023. Due to the relatively short-term nature of the debt, we believe that the carrying value approximates fair value.
Concentrations of Credit Risk | Concentrations of Credit Risk – Our customers consist of semiconductor manufacturers worldwide, as well as the lapping and polishing marketplace. Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and trade accounts receivable. Credit risk is managed by performing ongoing credit evaluations of the customers’ financial condition, by requiring significant deposits where appropriate, and by actively monitoring collections. Letters of credit are required of certain customers depending on the size of the order, type of customer or its creditworthiness, and country of domicile. As of December 31, 2021, one Semiconductor segment customer individually represented 23% of accounts receivable. As of September 30, 2021, one Semiconductor customer individually represented 14% of accounts receivable. We maintain our cash and cash equivalents in multiple financial institutions. Balances in the United States, which account for approximately 84% and 83% of total cash balances as of December 31, 2021 and September 30, 2021, respectively, are primarily invested in U.S. Treasuries or are in financial institutions insured by the Federal Deposit Insurance Corporation. The remainder of our cash is maintained with financial institutions with reputable credit in China, the United Kingdom and Malaysia. We maintain cash in bank accounts in amounts which at times may exceed federally insured limits. We have not experienced any losses on such accounts. Refer to Note 11 to Condensed Consolidated Financial Statements for information regarding major customers, foreign sales and revenue in other countries subject to fluctuation in foreign currency exchange rates.
Impact of Recently Issued Accounting Pronouncements | Impact of Recently Issued Accounting Pronouncements There were no new accounting pronouncements issued or effective as of December 31, 2021 that had or are expected to have a material impact on our consolidated financial statements.
