Proposal 1:

At meetings held on May 29-31, 2025 (the "Board Meetings"), the Board approved certain changes to the investment objectives, strategies, guidelines and policies of the Fund, pursuant to which the Fund will primarily focus on asset-based finance investments with a multi-sector investment

approach that seeks the most attractive relative value and risk-adjusted returns from investments across a range of sectors (such changes, collectively, the "Conversion"). As part of the Conversion, the Fund's name is also expected to be changed to "KKR Asset-Based Finance Fund". The Adviser has served as the Fund's investment adviser since its inception pursuant to the terms of an investment advisory agreement with the Fund dated January 17, 2020 (the "Existing Advisory Agreement"). In connection with the Conversion, the Adviser has proposed that the Existing Advisory Agreement be replaced by a new investment advisory agreement, subject to shareholder approval, which would reflect changes to certain material terms reflecting the services to be provided by the Adviser following the Conversion, the level and structure of the fees generally charged for such services, and the alignment of the Adviser's compensation to the Fund's ability to generate income (such new investment advisory agreement being referred to herein as the "New Advisory Agreement"). At the Board Meetings, the Board, including a majority of the Independent Trustees, considered and unanimously approved of the New Advisory Agreement, subject to shareholder approval.

The New Advisory Agreement would reflect the following material changes, arising from and consistent with the purposes of the Conversion:

The foregoing changes and other information regarding the New Advisory Agreement and the Conversion, including any expected tax consequences for Shareholder sin connection with the Conversion, are discussed in detail under "Proposal 1: Approval of New Advisory Agreement" in the Proxy Statement. See "Proposed New Advisory Agreement" and "Comparison of the Advisory Agreements" in the Proxy Statement for additional information and detail regarding the fees and expenses payable under the New Advisory Agreement and the Existing Advisory Agreement.

Shareholder approval of the proposed New Advisory Agreement is a critical component of the Fund's Conversion, and the Board recommends a vote "FOR" Proposal 1.

Proposal 2:

The Fund is an "interval fund," a type of fund that, in order to provide liquidity to shareholders, conducts quarterly repurchase offers of its outstanding shares at net asset value. The Fund currently maintains a fundamental policy pursuant to Rule 23c-3(b) under the Investment Company Act of 1940, as amended (the "1940 Act"), to conduct periodic repurchase offers of 10% to 25% of its outstanding Shares at net asset value, subject to approval of the Board.

In connection with the Conversion, the Adviser proposed, and the Board considered and unanimously approved, changing the Fund's fundamental policy to require the Fund to conduct quarterly repurchase offers of 5% to 25%. The Conversion would result in the Fund having different investment objectives, strategies, guidelines and policies, which, in the Adviser's view, makes changing the Fund's fundamental policy advisable and in the best interests of the Fund and shareholders, as it would permit the Fund to, among other things, more fully deploy investable capital in accordance with its investment strategies. A majority of the Fund's interval fund peers (both prior to and following the Conversion) also have fundamental policies that require them to make periodic repurchase offers of 5% to 25%, consistent with the requirements of Rule 23c-3.

The foregoing changes and other information regarding the Fund's fundamental policy to conduct repurchase offers are discussed under "Proposal 2: Approval of Change to Fundamental Policy" in the Proxy Statement.

Shareholder approval of the proposed change to the Fund's fundamental policy to conduct repurchase offers is a critical component of the Fund's Conversion, and the Board recommends a vote "FOR" Proposal 2.

Proposal 3

Mr. Pimentel currently serves as a Trustee and is deemed to be an "interested person" of the Fund as defined in the 1940 Act. Ms. Perez-Berkeley currently serves as a Trustee and is not deemed to be an "interested person" of the Fund as defined in the 1940 Act. Each of Mr. Pimentel and Ms. Perez-Berkeley (each, a "Nominee" and, together, the "Nominees") were appointed by the Trustees to fill vacancies on the Board. The Board believes that it is in shareholders' best interest to have a Board that is, to the extent possible, composed of Trustees who have been elected by the Fund's shareholders. Because a shareholder vote is required to approve Proposals 1 and 2, the Board has proposed that shareholders elect Mr. Pimentel and Ms. Perez-Berkeley during the same shareholder meeting, which would avoid the expense of preparing and mailing another proxy statement solely for the election of a Trustee.

The Fund's Nominating Committee, which is responsible for considering and presenting to the Board candidates it proposes for nomination as a Trustee of the Fund, recommended that the Nominees stand for election. The Nominating Committee also considered the Nominees' skills and background and noted that their past and current experience makes them well suited to continue serving on the Board. At the Board Meetings, the Board approved the Nominating Committee's recommendation that the Nominees stand for election.

The Board recommends a vote "FOR" approval of Proposal 3.

On September 17, 2025, the Board considered whether to reconvene the Meeting and continue to solicit shareholders participation on the Proposals or to take other action. For the reasons set out above, the Board determined that it remains in the best interest of the Fund to approve the Proposals, recognizing that the Meeting must be reconvened and that the continuation of the solicitation of the Fund's shareholders would be required. In connection with this solicitation, the Board approved a new record date of September 17, 2025 and determined that the Meeting be reconvened on November 12, 2025. The reconvened Meeting will be held at 10:00 a.m. Eastern time.

IF YOU WISH TO CHANGE YOUR VOTE or have changed brokerage accounts, you will need to vote again. Please promptly vote by Internet or telephone, or complete, sign, date and return the enclosed proxy card following the directions thereon.

Please vote now. Your vote is important.

To avoid the wasteful and unnecessary expense of further solicitation and no matter how large or small your holdings may be, we urge you to indicate your voting instructions on the enclosed proxy card, if received by mail, date and sign it and return it promptly in the postage-paid envelope provided, or record your voting instructions by Internet or telephone. If your shares are held through a broker, you must provide voting instructions to your broker about how to vote your shares in order for your broker to vote your shares as you instruct at the Meeting.

NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

TO BE RECONVENED ON NOVEMBER 12, 2025

NOTICE IS HEREBY GIVEN that the special meeting of the shareholders (the "Meeting") of KKR Credit Opportunities Portfolio (the "Fund") that was convened on August 25, 2025 and was adjourned to September 12, 2025, will be reconvened on November 12, 2025 and held at 10:00 a.m., Eastern time at the offices of Dechert LLP, 1095 Avenue of the Americas, 28th Floor, New York, New York 10036.

The Meeting is being held for the following purposes:

Each of the Proposals referenced above is discussed in the definitive proxy statement related to the Meeting (the "Proxy Statement") that was either previously mailed to you or is included with these supplemental proxy materials. Appendix A to the Proxy Statement includes the proposed new Investment Advisory Agreement between the Fund and the Adviser on which shareholders are being asked to vote in connection with Proposal 1.

The Board of Trustees (the "Board") of the Fund has fixed the close of business on September 17, 2025 as the record date for the determination of shareholders entitled to notice of, and to vote at, the reconvened Meeting or any adjournments or postponements thereof.

As of the record date of September 17, 2025, the Fund had 26,352,507 shares of beneficial interest (the "Shares") outstanding. As of September 17, 2025, no Shareholder, to the knowledge of the Fund, other than KKR, owned beneficially or of record more than 5% of the Shares.

A quorum of shareholders is constituted by the presence at the Meeting, in person or by proxy, of one-third (33-1/3%) of the Shares entitled to vote. If a quorum is not present at the Meeting, or if a quorum is present at the Meeting, but sufficient votes to approve any of the proposed items are not received, the Chair of the Meeting may propose one or more adjournments of the Meeting to permit further solicitation of proxies.

Proposals 1 and 2 require approval by a "vote of a majority of the outstanding voting securities" of the Fund. The "vote of a majority of the outstanding voting securities" is defined in the Investment Company Act of 1940, as amended, as the lesser of the vote of (i) 67% or more of the voting securities of the Fund entitled to vote thereon present at the Meeting or represented by proxy, if more than 50% of the Fund's outstanding voting securities are present or represented by proxy; or (ii) more than 50% of the outstanding voting securities of the Fund entitled to vote thereon. Proposal 3 requires the affirmative vote of a majority of the Fund's Shares, regardless of class, present in person or by proxy and entitled to vote. Abstentions will be considered as votes cast and, accordingly, will have the same effect as votes "AGAINST" the proposals. Abstentions will be included when determining the presence of a quorum. Shares for which brokers or other custodians have not received voting instructions from the beneficial owner of the Shares (which are considered "broker non-votes" with respect to such proposals) will be treated as Shares present for quorum purposes. All voting instruction forms timely received by the broker or other custodian that holds your Shares, and not duly revoked, will be voted in accordance with the instructions marked thereon.

Broker non-votes occur when a meeting has (1) a "routine" proposal, such as the election of Trustees, where brokers are permitted to vote their clients' shares in their discretion, and (2) a "non-routine" proposal, where brokers are not permitted to vote their clients' shares in their discretion. The shares that are considered to be present as a result of the broker discretionary vote on a routine proposal but that are not voted on a non-routine proposal are called "broker non-votes." Proposals 1 and 2 at the Meeting are considered a "non-routine" matters for which uninstructed shares may not be voted by brokers or other custodians. Proposal 3 with respect to the election of Trustees is considered a "routine" matter, and beneficial owners who do not provide proxy instructions or who do not return a proxy card may have their shares voted by brokers on Proposal 3 at the Meeting in the discretion of such brokers.

If the enclosed proxy card is properly executed and returned in time to be voted at the Meeting and has not been revoked, the Shares represented thereby will be voted "FOR" the proposals listed above, unless instructions to the contrary are marked thereon, and in the discretion of the proxy holders as to the transaction of any other business that may properly come before the Meeting or any postponements or adjournments thereof.

IF YOU DO NOT WISH TO CHANGE YOUR VOTE -NO ACTION IS NECESSARY. Unless we receive instructions from you to the contrary, the vote instructions you previously submitted will remain in effect for shares you held on the new record date.

IF YOU WISH TO CHANGE YOUR VOTE or have changed brokerage accounts, you will need to vote again. Please promptly vote by Internet or telephone, or complete, sign, date and return the enclosed proxy card or voter instruction form following the directions thereon.

The voting methods provided will reduce the time and costs associated with the proxy solicitation and will eliminate your receipt of follow-up telephone calls and additional mailings urging you to vote your shares. Whichever method you choose, please read the full text of the Proxy Statement before you vote.

We greatly appreciate your time and your investment in the Fund.

By order of the Board of Trustees,

Lori Hoffman

Secretary of the Fund
