| Auditor Opinion | Opinion on the financial statements We have audited the accompanying consolidated balance sheets of A-Mark Precious Metals, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of June 30, 2025 and 2024, the related consolidated statements of income, stockholders’ equity, and cash flows for each of the three years in the period ended June 30, 2025, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of June 30, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended June 30, 2025, in conformity with accounting principles generally accepted in the United States of America. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of June 30, 2025, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our report dated September 10, 2025 expressed an unqualified opinion. |
