| Amendment Description | Restatement BackgroundIn connection with the preparation and review of the Richtech Robotics Inc. (the “Company”) financial statements for the quarter ended March 31, 2026, management identified errors in the Company’s previously issued financial statements for the fiscal years ended September 30, 2025 and 2024 and unaudited interim financial statements for the periods ended December 31, 2024, March 31, 2025, June 30, 2025 and December 31, 2025 (collectively, the “Affected Financial Statements”). As a result of these findings, on June 9, 2026, the audit committee, in consultation with the Company’s management, determined that the Affected Financial Statements should no longer be relied upon.Additionally, the Company determined that any previously issued or filed reports, including financial statements, and other communications describing the Affected Financial Statements and related financial information should no longer be relied upon.The identified errors primarily relate to the Company’s accounting for warrants issued in connection with equity financing transactions, employee and nonemployee stock-based compensation arrangements, transactions executed under a Standby Equity Purchase Agreement dated as of February 15, 2024, with YA II PN, Ltd. (“SEPA”) and related notes payable, inventory and property and equipment classifications, and the classification of certain operating expenses. Specifically, the Company did not appropriately evaluate and record certain warrants, including placement agent warrants that should have been recognized as nonemployee share-based compensation and classified within mezzanine equity, as well as pre-funded warrants, common warrants, and common inducement warrants that should have been recognized as liabilities and subsequently remeasured at fair value each reporting period. As a result, certain balances were improperly classified among liabilities, mezzanine equity, and additional paid-in capital, and changes in fair value were not appropriately recognized in earnings. In addition, certain stock-based compensation awards, including awards requiring mezzanine equity classification, were improperly accounted for, resulting in misstatements of additional paid-in capital and compensation expense. The Company also identified errors in its accounting for the SEPA and related notes payable, including the failure to appropriately recognize the SEPA as a derivative instrument and to properly account for settlements of liabilities through the issuance of common stock. Further, certain costs of revenue and research and development expenses were incorrectly classified within general and administrative expenses. The Company also identified errors related to inventory and property and equipment, including the incorrect classification of certain inventory purchases as property and equipment and the miscategorization of certain fixed assets, which resulted in misstatements of inventory, property and equipment, depreciation expense, and cost of revenue. Additionally, certain intangible assets were not appropriately accounted for due to revisions to their estimated useful lives, resulting in shorter amortization periods (collectively, the “Errors”).Restatement of Previously Issued Financial StatementsThis Amendment to the Annual Report on Form 10-K/A (“Form 10-K/A”) is being filed to include audited consolidated financial statements as of and for the fiscal years ended September 30, 2025 and 2024. The Company has restated certain information within this Form 10-K/A, including the consolidated financial statements for the fiscal years ended September 30, 2025 and 2024 and certain related disclosures, as well as applicable comparative interim financial information for the quarterly periods ended December 31, 2024, March 31, 2025 and June 30, 2025 within fiscal year 2025.In addition to the restatement adjustments described above, the Company also evaluated other identified errors that were determined to be immaterial, individually and in the aggregate, to the previously issued financial statements for the impacted periods. Such items have been corrected in the period presented in this Form 10-K/A. The Company evaluated the identified misstatements in accordance with Accounting Standards Codification (“ASC”) 250, Accounting Changes and Error Corrections, and SEC Staff Accounting Bulletin No. 99 (“SAB 99”), considering both quantitative and qualitative factors. Based on this evaluation, the Company concluded that the errors were material to the previously issued financial statements for the impacted periods. Accordingly, the Company has restated the affected financial statements to reflect correction of these errors.See Note 2 and Note 3, Restatement of Previously Issued Financial Statements, to the consolidated financial statements included in Part II, Item 8 of this Form 10-K/A for additional information regarding the restatement, including a description of the Errors and the impact on the Company’s consolidated financial statements and related disclosures.Except as described above, no other information included in the original Form 10-K is being amended or updated by this Form 10-K/A and, other than as described herein, this Form 10-K/A does not purport to reflect any information or events subsequent to the original Form 10-K, including the deregistration of our joint venture company, Boyu Artificial Intelligence (Beijing) Co., Ltd. (“Boyu”), on April 3, 2026. This Form 10-K/A continues to describe the conditions as of the date of the original Form 10-K and, except as expressly contained herein, we have not updated, modified or supplemented the disclosures contained in the original Form 10-K. For updates on Boyu and other subsequent events, please see our periodic reports and current reports filed with the Securities and Exchange Commission (the “SEC”) on or after the date hereof. | |
