| Amendment Description | On March 14, 2024, RCM Technologies, Inc. (“Company,” “we,” “us,” “our” and “RCM”) filed its Annual Report on Form 10-K for the year ended December 30, 2023 (the “Original Filing”), with the Securities and Exchange Commission (the “Commission”). The Company indicated that it would incorporate Part III of Form 10-K in the Original Filing by reference to the Company’s definitive proxy statement for its 2024 annual meeting of stockholders. Because the Company does not anticipate filing its definitive proxy statement by April 29, 2024, the Company is filing this Amendment No. 1 (this “Amendment”) on Form 10-K/A, which amends and restates items identified below with respect to the Original Filing and provides the disclosure required by Part III of Form 10-K. This Form 10-K/A only amends information in Part III, Item 10 (Directors, Executive Officers and Corporate Governance), Item 11 (Executive Compensation), Item 12 (Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters), Item 13 (Certain Relationships and Related Transactions, and Director Independence), Item 14 (Principal Accounting Fees and Services) and Part IV, Item 15 (Exhibits, Financial Statement Schedules). All other items as presented in the Original Filing are unchanged. Except for the foregoing amended and restated information, this Amendment does not amend, update or change any other information presented in the Original Filing. In addition, as required by Rule 12b-15 of the Securities Exchange Act of 1934, this Form 10-K/A contains new certifications by our principal executive officer and our principal financial and accounting officer, filed as exhibits hereto. | ||
