Amendment Description This amendment to Form 10-Q (the “Amendment”) amends, but does not restate, the Quarterly Report on Form 10-Q of U.S. Global Investors, Inc. (the “Company”) for the quarter ended September 30, 2021 (the “Original Filing”), which was filed with the Securities and Exchange Commission (the “SEC”) on January 11, 2022. On the Original Filing, the Advisory fees amount of $6,470,000 did not appear on the face of the Consolidated Statements of Operations for the three months ended September 30, 2021. The subtotals correctly included the advisory fees amount and the amount was properly disclosed in the Notes to Consolidated Financial Statements. The amendment includes the Advisory fees amount that was inadvertently excluded from the Consolidated Statements of Operations in the original filing. Total operating revenues, net income, and basic and diluted net income per share are not impacted by the Amendment. Except as required to reflect the effects of the amendments described above, this Amendment does not affect any other items or sections in the Original Filing, and the Company has not updated the information contained herein to reflect events and transactions occurring subsequent to the date of the Original Filing on January 11, 2022.
