Amendment Description	Hudson Global, Inc. (the “Company” or “Hudson”, “we”, “us”, and “our”) is filing this Amendment (this “Amended Form 10-Q”) to its Quarterly Report on Form 10-Q/A for the quarter ended June 30, 2022 (the “Original Form 10-Q”), originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on August 11, 2022. As disclosed in the Company’s Current Report on Form 8-K, as filed with the SEC on March 30, 2023, the Company is restating its previously issued unaudited condensed consolidated financial statements for the three- and six-month periods ended June 30, 2022. Subsequent to the filing of the Original Form 10-Q, management identified an error related to the accounting treatment of a discretionary bonus paid by the Company on behalf of a customer. The effect of this error is an understatement of revenue and direct contracting costs and reimbursed expenses in the amount of $5.762 million for the three- and six-month periods ended June 30, 2022. This Amended Form 10-Q amends revenue and direct contracting costs and reimbursed expenses accordingly. The error had no impact on the Company’s consolidated balance sheet, consolidated statement of cash flows, net income, the presentation of the non-GAAP metric EBITDA, or any other accounts for such periods. Please see Note 16 to this Amended Form 10-Q, Restatement of Previously Reported Financial Statements for additional information and a summary of the accounting impacts of these adjustments.As a result of the error, the Company has concluded there was a material weakness in the Company’s internal control over financial reporting as of June 30, 2022 and that its disclosure controls and procedures were ineffective as of June 30, 2022. See additional discussion included in Part I Item 4 and Part II Item 1A of this Amended Form 10-Q.We are filing this Amended Form 10-Q to amend and restate the Original Form 10-Q with modification as necessary to reflect the restatement.
