The following discussion supplements the discussion contained under the heading “Certain U.S. Federal Income Tax Considerations” in the accompanying prospectus and supersedes such discussion to the extent inconsistent with such discussion.

#### The One Big Beautiful Bill Act
On July 4, 2025, President Trump signed into law the legislation known as the One Big Beautiful Bill Act, or the OBBBA. The OBBBA made significant changes to the U.S. federal income tax laws in various areas. Among the notable changes, the OBBBA permanently extended certain provisions that were enacted in the Tax Cuts and Jobs Act of 2017, most of which were set to expire after December 31, 2025. Such extensions included the permanent extension of the 20% deduction for “qualified REIT dividends” for individuals and other non-corporate taxpayers as well as the permanent extension of the limitation on non-corporate taxpayers using “excess business losses” to offset other income. The OBBBA also increased the percentage limit under the REIT asset test applicable to taxable REIT subsidiaries, or TRSs, from 20% to 25% for taxable years beginning after December 31, 2025. As a result, for taxable years beginning after December 31, 2025, the aggregate value of all securities of TRSs held by a REIT may not exceed 25% of the value of its gross assets. You are urged to consult with your tax advisor with respect to the OBBBA and its potential effect on investment in our common stock.
