...April 17, 2019 NEW YORK (S&P Global Ratings) April 17, 2019--S&P Global Ratings today assigned its '###' debt rating on Main Street Capital Corp.'s senior unsecured notes due 2024.

In the near term, the company intends to use the proceeds to repay a portion of the amount outstanding under its revolving credit facility and then re-borrow under this facility to repay notes due December 2019.
