New Accounting Standards
NW Holdings and NW Natural consider the applicability and impact of all accounting standards updates (ASUs) issued by the Financial Accounting Standards Board (FASB). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on consolidated financial position or results of operations.

Recently Issued Accounting Pronouncements
JOINT VENTURE FORMATIONS. In August 2023, the FASB issued ASU 2023-05, which requires a joint venture to initially measure all contributions received upon its formation at fair value. We adopted the standard in January 2025. The adoption of this standard did not have an impact on our results of operations, liquidity or capital resources.

SEGMENT REPORTING. In November 2023, the FASB issued ASU 2023-07, which requires additional disclosures about significant segment expenses. The disclosures were required beginning with the annual report for the year ending December 31, 2024. The adoption of this standard did not have an impact on our results of operations, liquidity or capital resources. See Note 4.

IMPROVEMENTS TO INCOME TAX DISCLOSURES. In December 2023, the FASB issued ASU 2023-09, which requires additional disclosures about income taxes. The disclosures are required beginning with this annual report for the year ending December 31, 2025. The adoption of this standard did not have an impact on our results of operations, liquidity or capital resources.

DISAGGREGATION OF EXPENSE DISCLOSURES. In November 2024, the FASB issued ASU 2024-03, which requires additional disclosures of disaggregated income statement expenses. The disclosures are required beginning with our annual report for the year ending December 31, 2027. The FASB issued ASU 2025-01 on January 6, 2025, to amend the effective date language of ASU 2024-03 clarifying that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. ASU 2025-01 did not impact the effective date of ASU 2024-03 for NW Holdings and NW Natural. The adoption of this standard is not anticipated to have an impact on our results of operations, liquidity, or capital resources.

FINANCIAL INSTRUMENTS-CREDIT LOSSES. In July 2025, the FASB issued ASU 2025-05, which simplifies how entities estimate credit losses on current accounts receivable and current contract assets arising from revenue transactions under ASC 606. It introduces a practical expedient that allows all entities to assume that economic conditions at the balance sheet date remain unchanged for the life of the asset, eliminating the need for forward-looking forecasts. This ASU is applicable only to current receivables and contract assets (typically due within one year) and is effective for fiscal years beginning after December 15, 2025. The adoption of this standard is not anticipated to have a material impact on our results of operations, liquidity or capital resources.

IMPROVEMENTS TO INTANGIBLE ASSET ACCOUNTING AND DISCLOSURES. 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 (“ASU 2025-06”). This ASU modernizes the accounting for software costs to adapt to an incremental and iterative software development method. ASU 2025-06 is effective for annual periods beginning after December 15, 2027, and may be applied using a prospective, modified prospective or retrospective transition approach. The adoption of this standard is not anticipated to have a material impact on our results of operations, liquidity or capital resources.

INTERIM REPORTING. In December 2025, the FASB issued ASU 2025-11, which improves the guidance in Topic 270, Interim Reporting, by clarifying the current disclosure requirements for interim periods. The ASU adds to Topic 270 a principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. The adoption of this standard is not anticipated to have an impact on our results of operations, liquidity, or capital resources.
CODIFICATION IMPROVEMENTS. In December 2025, the FASB issued ASU 2025-12, which makes changes to the Codification that clarify, correct errors, or make minor improvements. The amendments make the Codification easier to understand and apply. The amendments in this Update are varied in nature and may affect the application of guidance in cases in which the original guidance may have been unclear. ASU 2025-12 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. The adoption of this standard is not anticipated to have an impact on our results of operations, liquidity, or capital resources.

About New Standards Disclosures

New accounting standards disclosures describe recently adopted pronouncements and those not yet effective, along with management's assessment of their expected impact. This section provides an early warning system for upcoming changes to how a company reports its financial results, often years before the new rules take effect.

Key signals: when management describes a not-yet-adopted standard's impact as "material" or "still being evaluated," it signals potential significant changes to reported metrics upon adoption. Watch for standards that affect a company's core operations — for example, revenue recognition changes for software companies or lease accounting changes for retailers with large store footprints. The transition method chosen (full retrospective versus modified retrospective) affects comparability with prior periods. Companies that delay adoption to the latest permitted date may be struggling with implementation complexity. Compare the disclosed impact assessments against peers in the same industry to gauge whether management's expectations are reasonable.
