Carlyle Credit Income Fund

Vertical Capital Income Fund Announces Appointment of Carlyle as Investment Manager and Rebrand to Carlyle Credit Income Fund

NEW YORK, July 17, 2023 /PRNewswire/ — Vertical Capital Income Fund (NYSE: VCIF) (‘‘VCIF” or the “Company”) today announced that it has changed its corporate name from VCIF to Carlyle Credit Income Fund (“CCIF”) in connection with the closing of the previously announced transaction with global investment firm, Carlyle (NYSE: CG), and will begin trading under its new corporate name effective tomorrow. The Company will trade under the New York Stock Exchange ticker symbol CCIF, effective before the market opens on July 27, 2023. As part of the transaction closing, the Company will now focus on investing in equity and debt tranches of collateralized loan obligations (“CLOs”) in order to drive potential shareholder value.

In addition, Carlyle Global Credit Investment Management L.L.C., an affiliate of Carlyle (together with their affiliates, “Carlyle”), was appointed as CCIF’s external investment adviser, replacing Oakline Advisors, LLC, after shareholders voted to approve, among other things, a new investment advisory agreement between the Company and Carlyle at a special shareholder meeting held on June 15, 2023. The special shareholder meeting voting results were reported in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on June 15, 2023.

Carlyle has been investing in the credit markets for more than 20 years and is currently one of the world’s largest CLO managers. Carlyle’s seasoned team of investment professionals have extensive experience investing in, managing, and structuring CLOs. In addition, CCIF is able to leverage the broad resources of Carlyle, including the 20+ research analysts who support the firm. Carlyle currently has more than $150 billion in credit assets under management across a broad range of strategies, including liquid credit, private credit, and real assets credit.

“CLOs have a multi-decade track record of performing throughout various credit cycles and generating attractive total returns,” said Lauren Basmadjian, newly appointed Chief Executive Officer of CCIF. “This is an exciting time in the credit markets, and we are ready to capitalize on the opportunities CLOs offer on behalf of CCIF’s investors.”

As previously announced, Carlyle has made a special one-time payment to CCIF shareholders of $10,000,000, or approximately $0.96 per share. The one-time payment was made to Company shareholders of record as of the close of business on July 14, 2023.

In addition, Carlyle has made a $40 million equity commitment to CCIF, creating increased alignment between Carlyle and Company shareholders. Carlyle will launch a tender offer on July 18, 2023 for the purchase of up to $25,000,000 of CCIF shares. This is intended to provide CCIF shareholders with increased liquidity after the transaction closed. Carlyle will also make an

More information can be found in the Company’s January 12, 2023 press release announcing its definitive transaction agreement with Carlyle, and the Company’s definitive proxy statement dated May 22, 2023.

On July 17, 2023, the Company Board of Trustees declared a monthly common dividend of $0.0551, which is payable on July 31, 2023 to Company shareholders of record as of July 25, 2023. The monthly dividend represents an annualized yield of 8.0% based on $8.27 net asset value as of the closing of the transaction.

CCIF has launched a new website at www.carlylecreditincomefund.com, where more information about the Company and new management team can be found.
