BIODESIX INC New Standards Disclosure

Recently adopted accounting standards

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid by jurisdiction. This guidance became effective for the Company for the annual period beginning on January 1, 2025, and will be effective for interim periods beginning on January 1, 2026. The Company has adopted ASU 2023-09 for the year ended December 31, 2025, and applied the new disclosure requirements retrospectively to the prior period.

See Note 14 — Income Taxes for additional information.

Standards being evaluated

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. This ASU improves the transparency of a public business entity's expense disclosures by requiring more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation, amortization, and depletion) in commonly presented expense captions (such as cost of sales, SG&A, and research and development). This guidance will become effective for the Company for the annual period beginning on January 1, 2027, and interim periods beginning on January 1, 2028, with early adoption permitted. The Company is currently evaluating this guidance and assessing the overall impact on its 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. This ASU provides a practical expedient for entities estimating expected credit losses on current trade receivables and contract assets arising from revenue transactions accounted for under Topic 606. The practical expedient allows entities to assume that current economic conditions as of the balance sheet date do not change for the remaining life of the current accounts receivable and current contract assets. Therefore, an entity will not need to develop reasonable and supportable forecasts of future economic conditions. The practical expedient applies only to current accounts receivable and current contract assets. Entities electing to apply the practical expedient must do so consistently across all current accounts receivable and current contract assets arising from transactions accounted for under Topic 606. If adopted, this guidance will become effective for the Company for annual periods beginning after December 15, 2025, including interim periods within those annual periods with early adoption permitted and is required to be applied prospectively. The Company is currently evaluating the available elections under the new standard, including whether to adopt the practical expedient. However, based on our preliminary assessment, we do not expect the adoption of ASU 2025‑05 to have a material impact on our financial statements.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. This ASU clarifies the interim reporting requirements by improving navigability of Topic 270 and more clearly specifying what disclosures are required in an interim reporting period. It is not intended to significantly change interim reporting or expand or reduce interim disclosure

requirements. This guidance will become effective for the Company for the interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating this guidance and assessing the overall impact on its financial statements. However, based on our preliminary assessment, we do not expect the adoption of ASU 2025‑11 to have a material impact on our interim financial statements.
