Good morning,

Our records show that you may have client(s) invested in the KKR Credit Opportunities Portfolio (KCOP) who haven’t yet voted in the current proxy campaign. Every vote matters, so please encourage your clients to submit their vote—even if they don’t plan to attend the meeting.

The proxy seeks approval for changes to the Fund’s repurchase policy and investment management agreement as the Fund shifts toward Asset-Based Finance (ABF) investments. The special shareholder meeting is scheduled for November 12, 2025.

Prompt voting helps your client(s) avoid unnecessary follow-up outreach. If you need assistance identifying which of your client(s) have yet to cast their votes, please contact me directly. Broadridge representatives are on standby to assist clients with voting.

THE BOARD OF TRUSTEES RECOMMENDS SHAREHOLDERS VOTE “FOR” THE PROPOSAL.

Investors can vote one of the following ways:

1. Website: www.proxyvote.com (enter control number from proxy card included in the mailed notification)

2. Automated Phone: Call 1-800-690-6903 (enter control number)
