Investar Holding Corp New Standards Disclosure

Accounting Standards Adopted in 2025

FASB ASC Topic 740 “Income Taxes - Improvements to Income Tax Disclosures” Update No. 2023-09 (“ASU 2023-09”). On January 1, 2025, the Company adopted ASU 2023-09 using the retrospective method, which enhances the transparency and decision usefulness of income tax disclosures. ASU 2023-09 requires disclosure of additional categories of information about federal, state and foreign income taxes in the rate reconciliation table and requires companies to provide more information about the reconciling items in some categories if a quantitative threshold is met. The adoption of ASU 2023-09 did not have a material impact on the Company’s consolidated financial statements. The Company provided the required disclosures in Note 16. Income Taxes.

Recent Accounting Pronouncements

This section briefly describes accounting standards that have been issued, but are not yet adopted, that could impact the Company’s financial statements.

FASB ASC Topic 220 “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures: Disaggregation of Income Statement Expenses” Update No. 2024-03 (“ASU 2024-03”). In  November 2024, the FASB issued ASU 2024-03, which requires disaggregated disclosure of income statement expenses in a tabular format in the notes of the financial statements for public business entities. ASU 2024-03 is effective on a prospective basis for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption and retrospective application permitted. The Company is currently evaluating the provisions of the amendment and the impact on its future consolidated financial statements.

FASB ASC Topic 326 “Financial Instruments - Credit Losses (Topic 326): Purchased Loans.” Update No. 2025-08 (“ASU 2025-08”). In November 2025, the FASB issued ASU 2025-08, which expands the scope of the “gross‑up” method, formerly applicable only to PCD assets, to include acquired non‑PCD loans that meet certain criteria, now referred to as PSLs. Under this model, an ACL is recognized at acquisition, offsetting the loan’s amortized cost basis, thereby eliminating the day-one provision expense previously required for non‑PCD assets. PSLs are defined as non‑PCD loans acquired either (i) through a business combination, or (ii) purchased more than 90 days after origination when the acquirer was not involved in origination. ASU 2025-08 is effective for annual reporting periods beginning after December 15, 2026, including interim reporting periods, and must be applied prospectively. Early adoption is permitted in interim or annual reporting periods in which financial statements have not yet been issued. An entity that adopts the amendments in an interim reporting period may apply them as of the beginning of that interim reporting period or the beginning of the annual reporting period that includes that interim reporting period. The Company expects to early adopt ASU 2025-08 for the annual reporting period beginning on January 1, 2026. We are currently unable to reasonably estimate the impact of adopting ASU 2025-08 and will apply the guidance to loans purchased on or after January 1, 2026.

FASB ASC Topic 815 “Derivatives and Hedging (Topic 815): Hedge Accounting Improvements.” Update No. 2025-09 (“ASU 2025-09”). In November 2025, the FASB issued ASU 2025-09, which aligns hedge accounting more closely with an entity’s economic risk management practices. Key amendments include (i) to allow designating a variable price component of a nonfinancial forecasted purchase or sale as the hedged risk, (ii) to allow grouping individual forecasted transactions with similar (not identical) risk exposures, (iii) a new model for hedging forecasted interest on variable-rate debt, enabling changes in index or tenor without dedesignation, subject to simplifying assumptions, and (iv) additional clarifications related to hedge accounting of nonfinancial components, net written options, and dual-hedge strategies. ASU 2025-09 is effective on a prospective basis for annual reporting periods beginning after December 15, 2026. Early adoption is permitted. ASU 2025-09 is not expected to have a significant impact on our financial statements.
