In addition to the regular quarterly dividend for the second quarter of 2025, the Board of

Directors declared a supplemental quarterly cash dividend of $0.01 per share payable in May

Supplemental Quarterly Cash Dividend Payable in May 2025

Declared	Record Date	Payment Date	Amount Per Share
3/6/2025	3/31/2025	5/1/2025	$0.01

The second quarter regular quarterly cash dividend and the supplemental quarterly cash dividend

represent the Company’s first dividends declared subsequent to the Company’s listing on the

New York Stock Exchange on January 29, 2025.

The final determination of the tax attributes for dividends each year are made after the close of

the tax year. The final tax attributes for 2025 dividends are currently expected to include a

combination of ordinary taxable income and qualified dividends and may include capital gains

and return of capital.

The Company maintains a dividend reinvestment plan (the “DRIP”) which provides for the

reinvestment of dividends on behalf of its registered stockholders that have elected to participate

in the DRIP. Under the DRIP, if the Company declares a cash distribution to its stockholders,

the amount of such distribution will be automatically reinvested in additional shares of the

Company’s common stock unless a stockholder specifically “opts out” of the DRIP. If a

stockholder opts out, that stockholder will receive cash distributions.
