Kayne Anderson MLP Investment Company Announces Public Offering of Common Stock

Houston, TX — January 13, 2010 — Kayne Anderson MLP Investment Company (the “Company”) (NYSE: KYN) announced that it has commenced a public offering of 5,500,000 shares of its common stock. The Company also intends to grant the underwriters a 45-day option to purchase up to 825,000 additional shares of its common stock to cover over-allotments, if any. Net proceeds from the offering will be used to make additional portfolio investments that are consistent with its investment objective and for general corporate purposes.

“We believe the equity offering is well timed to take advantage of our expectation for continued strength in the MLP market. While we do not expect performance to be in line with the last three quarters, which saw the MLP market increase over 50%, we expect MLPs to continue to deliver low double-digit total returns over both the short term and long term,” stated Kevin McCarthy, Chief Executive Officer of the Company.

UBS Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., and Morgan Stanley & Co. Incorporated are acting as joint book-running managers for the equity offering.
