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, our 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 (“GAAP”). 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, 2022, has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP 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, 2022. 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, 2022, 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. 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. On March 28, 2022, the Chinese government issued a mandatory shutdown in Shanghai, the location of one of our manufacturing facilities. The factory was allowed to partially reopen in May 2022 and was fully reopened on June 1, 2022. Upon reopening on June 1, 2022, the factory was able to operate at near full capacity for the entire month of June. We were able to make up the shipments missed in the fourth quarter of fiscal 2022 and are now operating at normal capacity levels. Additionally, given the uncertainty surrounding the COVID-19 pandemic and the emergence of variations thereof, there can be no assurance that this facility will be allowed to remain open on a consistent basis in the future.
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 GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ 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 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, 2022 and September 30, 2022. Of the $7.2 million contract liabilities recorded at September 30, 2022, $0.6 million was recorded as revenue for the three months ended December 31, 2022. Warranty – A limited warranty is provided free of charge, generally for periods of 12 to 36 months to all purchasers of our new products and systems. Accruals are recorded for estimated warranty costs at the time revenue is recognized, generally upon shipment or acceptance, as determined under the revenue recognition policy above. On occasion, we have been required and may be required in the future to provide additional warranty coverage to ensure that the systems are ultimately accepted or to maintain customer goodwill. While our warranty costs have historically been within our expectations and we believe that the amounts accrued for warranty expenditures are sufficient for all systems sold through December 31, 2022, we cannot guarantee that we will continue to experience a similar level of predictability with regard to warranty costs. In addition, technological changes or previously unknown defects in raw materials or components may result in more extensive and frequent warranty service than anticipated, which could result in an increase in our warranty expense. Our accrued warranty expense is less than $1.0 million in all periods presented and is included in other accrued liabilities on the Condensed Consolidated Balance Sheets.

Our accrued warranty expense is less than $1.0 million in all periods presented and is included in other accrued liabilities on the Condensed Consolidated Balance Sheets.
Shipping Expense | Shipping Expense – Shipping and handling fees associated with outbound freight are expensed as incurred and included in selling, general and administrative expenses. Shipping expense was $0.6 million and $1.2 million for the three months ended December 31, 2022 and 2021, respectively.
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, 2022, one Semiconductor segment customer individually represented 14% of accounts receivable. As of September 30, 2022, one Semiconductor segment customer individually represented 12% of accounts receivable. We maintain our cash and cash equivalents in multiple financial institutions. Balances in the United States, which account for approximately 83% and 84% of total cash balances as of December 31, 2022 and September 30, 2022, respectively, are primarily invested in AAA-rated U.S Treasury and U.S. Government Agency repo money market mutual funds, which have a constant net asset value and consist of direct U.S. Treasuries and/or U.S. Government Agencies with repurchase agreements backed by U.S. Treasury or U.S. Government Agency collateral only, or are in financial institutions insured by the FDIC. 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 9 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, 2022 that had or are expected to have a material impact on our consolidated financial statements.
Correction of Immaterial Misstatements | Correction of Immaterial Misstatements During the preparation of the condensed consolidated financial statements for the period ended June 30, 2022, the Company identified certain immaterial misstatements related to the classification of sales discounts to distributors within our semiconductor reportable segment.  The Company previously presented these sales discounts as part of selling, general and administrative expenses instead of as a reduction of revenues in its unaudited condensed consolidated statements of operations for the three-month period ended December 31, 2021, and the three and six-month periods ended March 31, 2022, which resulted in overstatements of revenue and selling, general and administrative expenses for those periods. In accordance with Staff Accounting Bulletin No. 99, “Materiality,” the Company evaluated the misstatements and determined that the related impact was not material to the Company’s financial statements for any interim period. Accordingly, the Company revised the unaudited condensed consolidated statements of operations for the periods ended December 31, 2021 and March 31, 2022, including the related notes presented herein, as applicable. The misstatements did not impact operating income or net income in the condensed consolidated statements of operations, or the condensed consolidated balance sheets or the condensed consolidated statements of cash flows for any of those periods. A summary of the corrections to previously reported condensed consolidated statements of operations is as follows:
