The following table lists the Shares issued and total consideration for the Private Offering as of the date of this filing. The table below does not include Shares issued through the Company’s distribution reinvestment plan. The Company intends to continue selling Shares in the Private Offering on a monthly basis.

Private Notes Offering

On February 25, 2026, the Company entered into a Master Note Purchase Agreement (the “Note Purchase Agreement”) with the Purchasers listed therein (the “Purchasers”), which Note Purchase Agreement relates to the Company’s issuance and sale of (a) $85,000,000 aggregate principal amount of its 6.47% Series 2026A Senior Notes, Tranche A, due March 15, 2029 (the “March 2029 Notes”) and (b) $140,000,000 aggregate principal amount of its 6.89% Series 2026A Senior Notes, Tranche B, due March 17, 2031 (the “March 2031 Notes” together with the March 2029 Notes, the “Notes”) in a private placement in reliance on Section 4(a)(2) of the Securities Act. The Company is relying upon this exemption from registration based in part on representations made by the Purchasers. The Note Purchase Agreement also includes customary representations, warranties and covenants by the Company. The Notes have not been registered under the Securities Act and may not be offered or sold in the United States absent registration or an applicable exemption from registration.

The Notes may be redeemed in whole or in part at the Company’s option at any time prior to (i) December 15, 2028, in the case of the March 2029 Notes, and (ii) September 17, 2030, in the case of the March 2031 Notes, at par plus a “make-whole” premium, and thereafter at par. The March 2029 Notes bear interest at a rate of 6.47% per year and the March 2031 Notes bear interest at a rate of 6.89% per year, each payable semi-annually on March 15 and September 15 of each year, commencing on September 15, 2026. The Notes are the Company’s direct unsecured obligations and rank: pari passu with the Company’s other outstanding and future unsecured, unsubordinated indebtedness; senior to any of the Company’s future indebtedness that expressly provides it is subordinated to the Notes; effectively subordinated to all of the Company’s existing and future secured indebtedness (including indebtedness that is initially unsecured in respect of which the Company has granted or subsequently grants security), to the extent of the value of the assets securing such indebtedness; and structurally subordinated to all existing and future indebtedness and other obligations of any of the Company’s subsidiaries.

The closing of the private placement occurred on February 25, 2026. The net proceeds from the sale of the Notes were approximately $222 million, based on an offering price of 100% per Note, after deducting the placement agent fee and estimated offering expenses of approximately $3 million, each payable by the Company. The Company intends to use the net proceeds to repay outstanding indebtedness and for other general corporate purposes.
