Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires public business entities to disclose additional information in specified categories with respect to the reconciliation of the effective tax rate to the statutory rate for federal, state, and foreign income taxes. It also requires greater detail about individual reconciling items in the rate reconciliation to the extent the impact of those items exceeds a specified threshold. In addition to new disclosures associated with the rate reconciliation, the ASU requires information pertaining to taxes paid (net of refunds received) to be disaggregated for federal, state, and foreign taxes and further disaggregated for specific jurisdictions to the extent the related amounts exceed a quantitative threshold. The ASU also describes items that need to be disaggregated based on their nature, which is determined by reference to the item’s fundamental or essential characteristics, such as the transaction or event that triggered the establishment of the reconciling item and the activity with which the reconciling item is associated. The ASU eliminates the historic requirement that entities disclose information concerning unrecognized tax benefits having a reasonable possibility of significantly increasing or decreasing in the 12 months following the reporting date. This ASU is effective for annual periods beginning after December 15, 2024. This ASU should be applied on a prospective basis; however,

retrospective application is permitted. The Company adopted ASU 2023 - 09 effective January 1, 2025, on a prospective basis. The amendments enhance income tax disclosure requirements and are reflected in Note 7 – Income taxes.

In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosure (Subtopic 220-40): Disaggregation of Income Statement Expenses,” which requires additional disclosure about the specific expense categories in the notes to financial statements at interim and annual reporting periods. The amendments in this ASU do not change or remove current expense disclosure requirements but affect where this information appears in the notes to financial statements. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. Upon adoption, the guidance can be applied prospectively or retrospectively. The Company is currently evaluating the impact that ASU 2024-03 will have on its consolidated financial statements.

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. The ASU replaces the incurred-loss model with a forward-looking current expected credit loss model that requires recognition of lifetime expected credit losses on financial assets measured at amortized cost and certain off-balance-sheet credit exposures (including trade accounts receivable and contract assets), using historical experience, current conditions, and reasonable and supportable forecasts. This ASU is effective for interim and annual reporting periods beginning after December 15, 2025, with early adoption permitted. Upon adoption, the guidance can be applied prospectively or retrospectively. The Company adopted the practical expedient that current market conditions as of Balance Sheet date do not change the remaining life of the asset. The adoption did not have material impact on the Company’s Consolidated Financial Statements.

In September 2025, the FASB issued ASU 2025-06, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software,” which removes all references to software development project stages. The ASU requires entities to begin capitalizing software costs when management authorizes and commits to funding the software project, and it is probable that the project will be completed and the software will be used for its intended purpose. This ASU is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. Upon adoption, the guidance can be applied prospectively, retrospectively, or with a modified transition approach. The Company is currently evaluating the impact that ASU 2025-06 will have on its consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11, “Interim Reporting (Topic 270): Narrow-Scope Improvements,” which is intended to improve navigability of the guidance in Topic 270, Interim Reporting, and clarify when it applies. The ASU also addresses the form and content of such financial statements and interim disclosure requirements and establishes a principle under which an entity must disclose events from the end of the last annual reporting period that have a material impact on the entity. This ASU is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact that ASU 2025-11 will have on its consolidated financial statements and related disclosures.
