New Accounting Pronouncements Not Yet Adopted

In September 2025, the FASB issued an update that clarifies the threshold entities apply to begin capitalizing costs related to software. The standard removes all references to the project stages and requires entities to begin capitalizing software costs when both of the following occur: (1) management, with the relevant authority, implicitly or explicitly authorizes and commits to funding a computer software project and (2) it is probable that the project will be completed and the software will be used to perform the function intended. This update is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years. Early adoption and a prospective, retrospective or modified transition approach are permitted. Quanta is currently assessing the effect of this update.

In November 2024, the FASB issued an update that requires incremental disclosures about specific expense categories. Entities are required to disclose in the notes to financial statements the amounts of purchases of inventory, employee compensation, depreciation, intangible asset amortization and selling expense included in each relevant expense caption of the statements of operations. The standard also requires disclosure of the amount, and a qualitative description of, other items remaining in relevant expense captions that are not separately disaggregated. This update is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption and both prospective and retrospective application are permitted. Quanta is currently assessing the effect of this update.

In December 2023, the FASB issued an update that expands disclosures for tax rate reconciliation tables, primarily by requiring disaggregation of income taxes paid by jurisdiction, as well as greater disaggregation within the rate reconciliation. This update is effective for fiscal years beginning after December 15, 2024 and interim periods within fiscal years beginning after December 15, 2025. Early adoption and retrospective application are permitted. Quanta is currently assessing the effect of this update and will adopt it in its Form 10-K for the year ended December 31, 2025.
