(together with its consolidated subsidiaries, “we,” “us,” “our,” “CSL” or the “Company”) (NASDAQ: CGBD) and may only be used for informational purposes only. This Presentation should be viewed in conjunction with the earnings conference call of the Company held on August 10, 2022 and the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. 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. This Presentation provides limited information regarding the Company and is not intended to be taken by, and should not be taken by, any individual recipient as investment advice, a recommendation to buy, hold or sell, or an offer to sell or a solicitation of offers to purchase, our common stock or any other securities that may be issued by the Company, or as legal, accounting or tax advice. 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. 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. 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 them. 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 (the “SEC”), and it is not possible for us to predict or identify all of them. We undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. Information throughout the Presentation provided by sources other than the Company (including information relating to portfolio companies) has not been independently verified and, accordingly, the Company makes no representation or warranty in respect of this information. The following slides contain summaries of certain financial and statistical information about the Company. The information contained in this Presentation is summary information that is intended to be considered in the context of our SEC filings and other public announcements that we may make, by press release or otherwise, from time to time. We undertake no duty or obligation to publicly update or revise the information contained in this Presentation. CSL is managed by Carlyle Global Credit Investment Management L.L.C. (the “Investment Adviser”), an SEC-registered investment adviser and a wholly owned subsidiary of The Carlyle Group Inc. (together with its affiliates, “Carlyle”). This Presentation contains information about the Company and certain of its affiliates and includes the Company’s historical performance. You should not view information related to the past performance of the Company as indicative of the Company’s future results, the achievement of which is dependent on many factors, many of which are beyond the control of the Company and the Investment Adviser and cannot be assured. There can be no assurances that future dividends will match or exceed historical rates or will be paid at all. Further, an investment in the Company is discrete from, and does not represent an interest in, any other Carlyle entity. Nothing contained herein shall be relied upon as a promise or representation whether as to the past or future performance of the Company or any other Carlyle entity. 2
