Dear Stockholder:
You are cordially invited to the 2015 Annual Meeting of Stockholders of Cobalt International Energy, Inc. to be held
on Thursday, April 30, 2015 at 8:00 a.m., Central Time, at the Wisteria Ballroom in the Westin Houston Memorial
City Hotel, 945 Gessner Road, Houston, Texas 77024.
This booklet includes the notice of the meeting and the proxy statement, which contains information about the
Board of Directors and its committees and personal information about the nominees for the Board of Directors.
Other matters on which action is expected to be taken during the meeting are also described.
We use the internet as our primary means of furnishing proxy materials to our stockholders, including this proxy
statement, a proxy card and our 2014 annual report. Consequently, most stockholders will not receive paper copies
of our proxy materials. We will instead send these stockholders a notice with instructions for accessing the proxy
materials and voting via the internet. The notice also provides information on how stockholders may obtain paper
copies of our proxy materials if they so choose. Internet transmission and voting are designed to be efficient,
minimize cost and conserve natural resources.
Your vote is important and we encourage you to vote even if you are unable to attend the Annual Meeting. You may
vote by internet or by telephone using the instructions provided in the proxy materials, or, if you requested and
received a paper copy of the proxy card, by signing and returning it at your earliest convenience. You may also
attend and vote at the Annual Meeting.
It is important that your shares are represented at the Annual Meeting, as a quorum of the stockholders must be
present, either in person or by proxy, in order for the Annual Meeting to take place.
On behalf of the Board of Directors, thank you for your continued support.
Yours truly,
Joseph H. Bryant
Chairman of the Board of Directors and
Chief Executive Officer
March 20, 2015
