SUPPLEMENT TO THE PROXY STATEMENT

FOR THE SPECIAL MEETING OF SHAREHOLDERS

TO BE HELD ON DECEMBER 16, 2025

The following information supplements the definitive proxy statement (the “Proxy Statement”) of KKR Credit Opportunities Portfolio (the “Fund”) filed on Schedule 14A with the U.S. Securities and Exchange Commission (the “SEC”) on June 20, 2025, in connection with the solicitation of proxies by the Board of Trustees (the “Board”) of the Fund for the Special Meeting of Shareholders of the Fund (the “Special Meeting”) originally called for August 25, 2025 at 10:00 a.m. Eastern Time, and previously adjourned to September 12, 2025 and further adjourned to November 12, 2025 at 10:00 a.m. Eastern Time in order to solicit additional shareholder proxies.

On November 12, 2025, the Special Meeting was further adjourned to December 16, 2025 at 10:00 a.m. Eastern Time in order to solicit additional shareholder proxies.

This supplement to the Proxy Statement (this “Supplement”) is being filed with the SEC and being made available to shareholders on or about November 20, 2025.

Except as described in this Supplement, the information disclosed in the Proxy Statement remains in full force. To the extent that information in this Supplement differs from information disclosed in the Proxy Statement, the information in this Supplement will apply.

Withdrawal of Proposal 3 From Shareholder Consideration

The purpose of this Supplement is to withdraw from shareholder consideration at the Special Meeting Proposal 3 set forth in the Proxy Statement, which asked shareholders to elect two (2) nominees to the Board.

In light of the Board’s consideration of potential changes to the Board’s composition in connection with the Fund’s proposed conversion, the Board has decided that it is in the best interest of the Fund and its shareholders to seek approval of Proposal 3 at a separate special meeting of shareholders of the Fund in the near future called solely for that purpose. Seeking approval of Proposal 3 at a separate future meeting will allow the Board to further consider the appropriate Board composition. Accordingly, Proposal 3 is hereby withdrawn from shareholder consideration at the Special Meeting, and the Proxy Statement is hereby amended to remove Proposal 3 and related references therein. Except as amended by this Supplement, the Proxy Statement remains in full force.

The Fund will hold the Special Meeting (including any adjournments or postponements) as described below. At the Special Meeting, the Fund intends to hold a vote on all matters in the Proxy Statement except Proposal 3. No vote will be taken with respect to Proposal 3 at the Special Meeting. Therefore, any votes cast regarding Proposal 3 will be neither tabulated nor reported.

Following Removal of Proposal 3, Important Matters Regarding Voting

• The record date for determining the shareholders entitled to receive notice of, and to vote at, the Special Meeting has been set and remains as the close of business on September 17, 2025 (the “Record Date”).

• The Fund will not make available or distribute, and you do not need to sign, new proxy cards or submit new voting instructions solely as a result of the withdrawal of Proposal 3.

• Proxy cards or voting instructions received with direction on Proposal 3 will not be voted on Proposal 3. Proxy cards or voting instructions received and providing direction on the remaining proposals to be considered at the Special Meeting (i.e., Proposals 1 and 2) will remain valid and will be voted on those proposals as directed.

• 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 Record Date.

• If you wish to change your vote on Proposals 1 and 2 or have changed brokerage accounts, you must vote again. Please promptly vote by Internet or telephone, or complete, sign, date and return the proxy card previously provided to you following the directions thereon, disregarding Proposal 3.

• If you have not yet returned your proxy card or submitted voting instructions, please promptly vote by Internet or telephone, or complete, sign, date and return the proxy card previously provided to you following the directions thereon, disregarding Proposal 3.
