The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, the scaling back of, repeal of, and/or addition of stricter eligibility requirements for, several renewable-energy tax incentives, and the restoration of immediate deductibility of certain capital expenditures for tangible, depreciable personal property, and research and development expenditures. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. As of September 30, 2025, the Company’s tax provision includes the estimated effects of mandatory aspects of the OBBBA, the impact of which were not significant. We continue to assess the potential impacts of further tax planning elections allowed under the OBBBA.
