There have been no material changes to the risk factors previously described in Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. These risk factors describe some of the assumptions, risks, uncertainties and other factors that could adversely affect our business or that could otherwise result in changes that differ materially from our expectations. We may disclose changes to such risk factors or disclose additional risk factors from time to time in our future filings with the SEC.

Effective July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was signed into law. Certain provisions of OBBBA modified U.S. tax law and impact us and our shareholders. Among other changes, this legislation (i) permanently reinstated 100% bonus depreciation for certain property acquired after January 19, 2025, (ii) increases the base on which the 30% interest deduction limit under Section 163(j) of the Code applies by excluding depreciation, amortization and depletion from the definition of “adjusted taxable income” for taxable years beginning after December 31, 2024. We are currently evaluating the provisions of OBBBA, but do not expect it to have a material impact on our Financial Statements.
