Thank you for your continued support as a stockholder of FS KKR Capital Corp. We are currently asking our stockholders to vote on two proposals for our annual stockholder meeting.

The first proposal is to elect certain members of our board.

The second proposal allows FSK to sell its shares below net asset value (NAV) per share in future offerings. While we do not have any immediate plans to do so, having the option positions the fund to bolster liquidity in a market downturn and helps protect against any negative impact to valuations or credit performance during periods of volatility or market stress.

Your vote is important, regardless of how many shares you own. Please take a moment and cast your vote in one of these three ways: You can mail back your completed voting card, vote online at proxyvote.com by entering the control number on your voting card or call 1-833-868-3374.

Thank you again for your support. Your participation is very important to the future of FS KKR Capital Corp.
