ODYSSEY MARINE EXPLORATION INC New Standards Disclosure

Accounting Standards Recently Adopted

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740) – Improvements to Income Tax Disclosures”). The new guidance enhances the transparency and decision usefulness of income tax disclosures. Adjustments to the annual disclosure of income taxes include: (1) a tabular rate reconciliation comprised of eight specific categories, (2) incomes taxes paid, disaggregated between significant national, state, and foreign jurisdictions, (3) elimination of requirements to disclose the nature and estimate of reasonably possible changes to unrecognized tax benefits in the next 12 months or that an estimated range cannot be made, and (4) addition of a requirement to disclose income (or loss) from continuing operations before income tax expense (or benefit) by national and foreign, and income tax expense (or benefit) from continuing operations disaggregated between national, state and foreign. The ASU is effective for public business entities for fiscal years beginning on or after December 15, 2024, with early adoption permitted. The Company adopted this guidance in this Annual Report on Form 10-K on a prospective basis, which results in the requirement for some non-comparable disclosures between the periods presented. Except for the expanded disclosure, there was no material impact on the Company’s consolidated financial statements due to the adoption of this ASU. See Note 14 – Income Taxes for complete disclosures arising from this adoption.

In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) Disaggregation of Income Statement Expenses.” The guidance in ASU 2024-03 requires public business entities to disclose in the notes to the financial statements, among other things, specific information about certain costs and expenses, including purchases of inventory, employee compensation, and depreciation, amortization, and depletion expenses for each caption on the income statement where such expenses are included. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted, and the amendments may be applied prospectively to reporting periods after the effective date or retrospectively to all periods presented in the financial statements. The Company is currently evaluating the provisions of this guidance and assessing the potential impact on the Company’s consolidated financial statement disclosures.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets.

This guidance specifically scopes out litigation funding from the definition of a derivative.
