The information contained herein may not be used, reproduced, referenced, quoted, linked by website, or distributed to others, in whole or in part, except as agreed in writing by the Company. This Presentation does not constitute a prospectus and should under no circumstances be understood as an offer to sell or the solicitation of an offer to buy our common stock or any other securities nor will there be any sale of the common stock or any other securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of such state or jurisdiction.

An investment in securities of the type described herein presents certain risks. This Presentation may contain forward-looking statements that involve substantial risks and uncertainties. Some of the statements in this communication constitute forward-looking statements because they are not historical facts, but instead relate to future events, future performance or financial condition or the merger of CSL III with and into Carlyle Secured Lending, Inc. (“CGBD”) (collectively, the “Mergers”). The forward-looking statements may include statements as to: future operating results of CGBD and CSL III and distribution projections; business prospects of CGBD and CSL III and the prospects of their portfolio companies; and the impact of the investments that CGBD and CSL III expect to make. You can identify these statements by the use of forward-looking terminology such as “anticipates,” “believes,” “expects,” “intends,” “will,” “should,” “may,” “plans,” “continue,” “believes,” “seeks,” “estimates,” “would,” “could,” “targets,” “projects,” “outlook,” “potential,” “predicts” and variations of these words and similar expressions to identify forward-looking statements, although not all forward-looking statements include these words. The forward-looking statements contained in this Presentation involve risks and uncertainties. Certain factors could cause actual results and conditions to differ materially from those projected, including the uncertainties associated with (i) the timing or likelihood of the Mergers closing; (ii) the expected synergies and savings associated with the Mergers; (iii) the ability to realize the anticipated benefits of the Mergers, including the expected elimination of certain expenses and costs due to the Mergers; (iv) the percentage of CGBD stockholders voting in favor of the proposals submitted for their approval; (v) the possibility that competing offers or acquisition proposals will be made; (vi) the possibility that any or all of the various conditions to the consummation of the Mergers may not be satisfied or waived; (vii) risks related to diverting management’s attention from ongoing business operations; (viii) the risk that stockholder litigation in connection with the Mergers may result in significant costs of defense and liability; (ix) changes in the economy, financial markets and political environment, including the impacts of inflation and rising interest rates; (x) risks associated with possible disruption in the operations of CGBD and CSL III or the economy generally due to terrorism, war or other geopolitical conflict (including the uncertainty surrounding Russia’s military invasion of Ukraine and the impact of geopolitical tensions in other regions such as the Middle East, and developing tensions between China and the United States); (xi) future changes in laws or regulations (including the interpretation of these laws and regulations by regulatory authorities); (xii) conditions in CGBD’s and CSL Ill’s operating areas, particularly with respect to business development companies or regulated investment companies; and (xiii) other considerations that may be disclosed from time to time in CGBD’s and CSL Ill’s publicly disseminated documents and filings. CGBD and CSL III have based the forward-looking statements included in this Presentation on information available to them on the date hereof, and they assume no obligation to update any such forward-looking statements. You should read statements that contain these words carefully because they discuss our plans, strategies, prospects and expectations concerning our business, operating results, financial condition and other similar matters. We believe that it is important to communicate our future expectations to our investors. There may be events in the future, however, that we are not able to predict accurately or control. You should not place undue reliance on these forward-looking statements, which speak only as of the date on which we make it. Factors or events that could cause our actual results to differ, possibly materially from our expectations, include, but are not limited to, the risks, uncertainties and other factors we identify in the sections entitled “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements” in filings we make with the Securities and Exchange Commission, and it is not possible for us to predict or identify all of them. Although CGBD and CSL III undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, you are advised to consult any additional disclosures that they may make directly to you or through reports that CGBD and CSL III have filed or in the future may file with the Securities and Exchange Commission (“SEC”), including the Proxy Statement and the Registration Statement (each as defined below), annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K.
