Distribution Reinvestment Plan

The Company’s amended and restated distribution reinvestment plan (“DRIP”) provides for the reinvestment of distributions in the form of common stock on behalf of its stockholders, unless a stockholder has elected to receive distributions in cash. As a result, if the Company declares a cash distribution, its stockholders who have not “opted out” of the DRIP by the opt out date will have their cash distribution (net of applicable withholding tax) automatically reinvested into additional shares of the Company’s common stock. The share requirements of the DRIP may be satisfied through the issuance of common shares or through open market purchases of common shares by the DRIP plan administrator. Newly issued shares will be valued based upon the final closing price of the Company’s common stock on the valuation date determined for each distribution by the Board.

The Company’s DRIP is administered by its transfer agent on behalf of the Company’s record holders and participating brokerage firms. Brokerage firms and other financial intermediaries may decide not to participate in the Company’s DRIP but may provide a similar distribution reinvestment plan for their clients.

During the three months ended March 31, 2026, the Company issued 46,409 shares of common stock for a total of approximately $0.7 million under the DRIP.

During the year ended December 31, 2025, the Company issued 94,569 shares of common stock for a total of approximately $1.4 million under the DRIP.
