URGENT REQUEST REGARDING OUR SPECIAL MEETING PROXY YOUR VOTE IS NEEDED! Our Board of Directors recommends that you respond to this solicitation by voting FOR the proposal described in the previously provided proxy statement. Dear Stockholder, We are pleased to invite you to participate at the Special Meeting of Stockholders of Oaktree Specialty Lending Corporation (“OCSL”), to be held virtually on March 4, 2024 at 10:30 a.m. Pacific Time (1:30 p.m. Eastern Time) at the following website: Your participation is urgently needed to approve OCSL’s proposal outlined in the proxy materials previously sent to you. We kindly request that you review these materials and cast your vote by proxy in advance of the meeting date to ensure that a quorum is achieved. At the meeting, you will be asked to consider and vote on a proposal to authorize OCSL, with the approval of the Board of Directors, to sell or otherwise issue shares of its common stock at a price below its then current net asset value (“NAV”) per share, provided that the number of shares issued does not exceed 25% of its then outstanding common stock. While OCSL has no immediate plans to issue any shares of its common stock below NAV, OCSL is seeking stockholder approval now in order to provide flexibility if it desires in the future to issue shares of its common stock below NAV per share, which typically must be undertaken quickly. Your vote and participation are very important to us, no matter how many or few shares in OCSL you own. If you do not vote, the effect is the same as voting against this proposal. We encourage you to review the enclosed proxy materials carefully and vote your shares using any one of the methods described below. Your prompt response will help us meet stockholder approval requirements before the meeting, thereby reducing the risk of postponement and additional solicitation costs. If you have any questions about voting, please call our proxy solicitor, Broadridge, at 1-844-557-9030. Thank you for your continued support of OCSL.
