TSLX Encourages TICC Stockholders to Vote the GOLD Proxy Card to Terminate TICC’s External Adviser’s Advisory Contract and to Elect T. Kelley Millet to the TICC Board of Directors at the 2016 Annual Meeting on September 2, 2016

NEW YORK—(BUSINESS WIRE)—TPG Specialty Lending, Inc. (“TSLX”; NYSE:TSLX), a specialty finance company focused on lending to middle-market companies, today published a public letter to TICC Capital Corp. (“TICC”; NASDAQ:TICC) stockholders, encouraging them to vote the GOLD proxy card ahead of TICC’s 2016 annual meeting scheduled for this Friday, September 2, 2016.

TSLX strongly encourages stockholders to sign and return the GOLD proxy card today. Even if a WHITE card has been submitted, stockholders can still change their vote, simply by signing and returning the GOLD proxy card now.

Voting instructions and TSLX’s proxy materials are also available through the SEC’s website and at www.changeTICCnow.com.

A copy of the letter follows:

Dear Fellow TICC Stockholders,

TIME IS RUNNING OUT. You must act now to seize on the opportunity to finally end the failed performance of the external adviser of TICC Capital Corp. (“TICC” or the “Company”).

Listen to the outside proxy advisors. Do not listen to management’s self-interested arguments. All three leading proxy advisory firms have called for TICC stockholders to support TSLX’s campaign for change at TICC.

A vote on the GOLD proxy card is a vote to end…

Since its IPO in 2003, TICC has underperformed the BDC Composite by 183% ¹ while NAV per share has declined 52%. ²

Despite the Company’s history of continued underperformance, the external adviser has collected more than $141.4 million in management and incentive fees from stockholders’ investment since inception under a fee structure that is approximately 265% ³ higher than its most comparable peer. ⁴

The Board has consistently demonstrated an interest in helping itself instead of delivering true value for stockholders. This includes:

IT IS NOT TOO LATE TO CAST YOUR VOTE! SIGN AND RETURN THE GOLD CARD TODAY TO SUBMIT YOUR SUPPORT FOR TSLX’S PROPOSAL TO TERMINATE THE EXISTING ADVISORY AGREEMENT AND TO ELECT TSLX’S NOMINEE, T. KELLEY MILLET. Even if you have already submitted a WHITE card, you can still change your vote by simply signing and returning the GOLD proxy card now.

Stockholders, YOU have the power to effect change at TICC and protect your investment. YOU are the true owners of the Company and YOU should exercise your right to VOTE the GOLD card in favor of TSLX’s proposals.

If you have not yet voted, or would like to change your vote, IT IS NOT TOO LATE. Vote today to end a decade of failure at TICC and set TICC on a better path forward.

Sincerely,

TPG Specialty Lending, Inc.
