About this offering.

We are offering to sell up to 25,000,000 shares of our common stock from time to time through our “

Sales Agents

”, Jefferies LLC and Citizens JMP Securities LLC. Any such sales may be made in negotiated transactions or transactions that are deemed to be “at the market” (as defined in Rule 415 of the Securities Act). “At the market” transactions may be made directly on the NYSE or another securities exchange or through a market maker (other than a securities exchange). Any such sales of our common stock may be made at prices related to the prevailing market price or at negotiated prices. Our arrangement with the Sales Agents is governed by Equity Distribution Agreements, dated May 5, 2023. Under those Agreements, the Sales Agents will receive a commission from us for sales of common stock. The amount of each Sales Agent’s commission will be negotiated from time to time but will never exceed 2.0% of the gross sales price of common stock sold through the Sales Agent under the applicable Equity Distribution Agreement. The Sales Agents are not required to sell any of our common stock but will use their commercially reasonable efforts, consistent with their sales and trading practices, to effect sales. For more information, see “

Plan of Distribution

” beginning on pages

S-3

of this amendment and 79 of the prospectus supplement.

ABOUT THIS AMENDMENT TO THE PROSPECTUS SUPPLEMENT

The prospectus supplement amendment is part of a registration statement that we have filed with the Securities and Exchange Commission using the “shelf” registration process as a “well-known seasoned issuer,” as defined in Rule 405 under the Securities Act of 1933, as amended, or the Securities Act. On August 15, 2024, we obtained authorization from our stockholders to issue common stock at a price below our then-current NAV per share for a twelve-month period expiring on August 15, 2025, subject to certain conditions. This amendment is modifying certain disclosures in the prospectus supplement and accompanying prospectus relating to

Below-NAV

Sales.

The prospectus supplement, as amended by this amendment, describes the terms of this offering of common stock and also adds to and updates information contained in the documents incorporated by reference into the prospectus supplement and the accompanying prospectus. To the extent there is a conflict between the information contained in this amendment or the prospectus supplement, on the one hand, and the information contained in any document incorporated by reference into the prospectus supplement and the accompanying prospectus that was filed with the SEC before the date of this amendment or the prospectus supplement, on the other hand, you should rely on the information in this amendment or the prospectus supplement, as applicable.

The Offering

Offering price:

Any sales of our common stock in this offering may be made at prices related to the prevailing market price or at negotiated prices.

We are not generally able to sell our common stock at a price per share below NAV unless our Board determines that such sale is in the best interests of our stockholders and if stockholders (including a majority of those stockholders that are unaffiliated with us) approve the sale. Any sale or other issuance of shares of our common stock at a price below NAV per share would result in an immediate dilution to your interest in our common stock and a reduction of our NAV per share.

On August 15, 2024, we obtained authorization from our stockholders to issue common stock at a price below our then-current NAV per share for a twelve-month period expiring on August 15, 2025. We may seek to obtain this authorization again in the future. The stockholder authorization is subject to the following conditions and stockholder protections:

•

The number of shares of our common stock sold or issued in

Below-NAV

Sale may not exceed 25% of the number of then-current outstanding shares of our common stock.

•

The purchase price of each share of our common stock sold in a

Below-NAV

Sale may not be more than 25% below the then-current NAV per share of our common stock.

•

The Board will consider the potential dilutive effect of any

Below-NAV

Sale when considering whether to authorize any such

Below-NAV

Sale.

•

The prospectus or offering memorandum pursuant to which any

Below-NAV

Sale is conducted will include a chart based on the actual number of shares of our common stock to be offered, the purchase price of such shares of our common stock and the actual discount of the purchase price relative to the most recently determined NAV per share of our common stock.

•

A majority of our independent directors who have no financial interest in the proposed

Below-NAV

Sale (the “

Required Majority

S-1

of Directors

”) must determine that each

Below-NAV

Sale is in the best interests of the Company and its stockholders prior to approving any such

Below-NAV

Sale.

•

Prior to approving any

Below-NAV

Sale that will be conducted as an underwritten offering, a Required Majority of Directors, in consultation with the underwriter(s) of the offering, must determine in good faith, and as of a time immediately prior to the first solicitation by or on behalf of the Company of firm commitments to purchase shares of our common stock or immediately prior to the

Below-NAV

Sale, that the price at which such shares of our common stock are to be sold in the

Below-NAV

Sale is not less than a price that closely approximates the market value of the shares of our common stock, less any distributing commission or discount.

Even though we have obtained authorization from our stockholders to issue common stock at a price below our then-current NAV, we cannot predict whether we will make any

Below-NAV

Sales under the prospectus supplement, as supplemented by this amendment. For more information about the impact of the sale of our common stock at a price per share below NAV, please see “Sales of Common Stock Below Net Asset Value” beginning on page

S-3

of this amendment.

RISK FACTORS

The following disclosure supersedes and replaces the first paragraph of the risk factor titled “Stockholders may incur dilution if we sell shares of our common stock in one or more offerings at prices below the then-current NAV per share of our common stock or issue securities to subscribe to, convert to or purchase shares of our common stock.” on page

S-3

of the Amendment No. 1 to the prospectus supplement dated August 18, 2023:

The 1940 Act prohibits us from selling shares of our common stock at a price below the current NAV per share of such stock, with certain exceptions. One such exception is prior stockholder approval of issuances below NAV provided that our Board makes certain determinations. On August 15, 2024, we obtained authorization from our stockholders to issue common stock at a price below our then-current NAV per share for a twelve-month period expiring on August 15, 2025. We may seek to obtain this authorization again in the future. Our stockholders have previously approved a proposal to authorize us to issue securities to subscribe to, convert to, or purchase shares of our common stock in one or more offerings. Even though we have obtained authorization from our stockholders to issue common stock at a price below our then-current NAV, we cannot predict whether we will make any

Below-NAV

Sales under the prospectus supplement, as supplemented by this amendment. Any decision to sell shares of our common stock below the then-current NAV per share of our common stock or securities to subscribe to, convert to, or purchase shares of our common stock would be subject to the determination by our Board that such issuance is in our and our stockholders’ best interests.
