Exhibit 99.1

Leading Independent Proxy Advisory Firms ISS and Glass Lewis Recommend that Shareholders Vote “FOR” the Pending Merger between OBDC and OBDE

NEW YORK – January 3, 2025 – Blue Owl Capital Corporation (NYSE: OBDC) and Blue Owl Capital Corporation III (NYSE: OBDE) today announced that leading independent proxy advisory firms, Institutional Shareholder Services ("ISS") and Glass Lewis & Co. ("Glass Lewis"), have recommended that OBDE shareholders vote “FOR” the pending merger between OBDC and OBDE, and that OBDC shareholders vote “FOR” both proposals associated with the merger at upcoming special meetings on January 8, 2025.

In its report dated January 2, 2025, ISS stated, “The strategic rationale for the merger appears sound. Specifically, the combined company will have increased scale that may improve trading dynamics and long-term expense savings from operating synergies.” In its report dated December 24, 2024, Glass Lewis said, “Given their largely similar investment mandates, portfolio strategies, and risk-return profiles, we believe a merger of these two BDCs should be relatively straightforward to execute.”

Craig W. Packer, Chief Executive Officer of OBDC and OBDE said, “We are pleased that ISS and Glass Lewis support our Boards’ unanimous recommendation that shareholders vote “FOR” the pending merger. The merger is expected to significantly enhance OBDC’s scale and diversification, which will result in the second largest publicly traded BDC by total assets.”

With the special meetings approaching on January 8, 2025, OBDC and OBDE would like to remind shareholders that their vote is very important regardless of the number of shares they own and urge all shareholders to vote by one of the methods described in the proxy statement before 11:59 p.m. Eastern Time on January 7, 2025.

Additional information on the proposed merger, including links to the joint prospectus and proxy statement, can be found at www.proxyvote.com. Shareholders who have questions about the joint prospectus and proxy statement or about voting their shares should contact the companies’ proxy solicitor, Broadridge, at 1-866-584-0652 for OBDC shareholders and 1-877-495-1274 for OBDE shareholders.
