NEWS RELEASE
Cobalt International Energy, Inc. Announces Fourth Quarter and
Year-End 2012 Results and Provides Operational Update on its
Gulf of Mexico and West Africa Drilling Operations
HOUSTON, TX— February 26, 2013 (BUSINESS WIRE) — Cobalt International Energy, Inc. (“Cobalt”) (NYSE:CIE) today announced a net loss of $67 million, or $0.16 per basic and diluted share for the fourth quarter of 2012, compared to a net loss of $51 million, or $0.13 per basic and diluted share, for the fourth quarter of 2011. Cobalt reported a net loss of $283 million, or $0.70 per basic and diluted share, for the year ended December 31, 2012, compared to a net loss of $134 million, or $0.35 per basic and diluted share, for the same period in 2011.
Cash expenditures (excluding changes in working capital) for the year 2012 were approximately $620 million. Cobalt estimates cash expenditures will be between $750 and $900 million for the year 2013. The range is primarily dependent on the appraisal and development activity associated with the existing discoveries.
Cash, cash equivalents and investments at year-end 2012 were approximately $2.7 billion. This includes about $500 million designated for future operations held in escrow and collateralizing letters of credit, but excludes approximately $95 million in the TOTAL drilling fund for the U.S. Gulf of Mexico.
Operational Update
Cobalt today provided an update regarding its Shenandoah #2R appraisal well, located in Walker Ridge Block 51 in the deepwater Gulf of Mexico. While evaluation operations are still ongoing in this well, wireline evaluation results received thus far are very encouraging.
The Shenandoah #2R appraisal well was drilled as a straight hole to a total depth of 31,400 feet in approximately 5,800 feet of water, about 1.3 miles southwest of the Shenandoah #1 discovery well. The Shenandoah #1 discovery well was drilled in early 2009 on Walker Ridge Block 52 and encountered nearly 300 net feet of Inboard Lower Tertiary oil pay.
“We are extremely pleased with the results of the Shenandoah appraisal well to date, as they provide further evidence that Shenandoah has the potential to hold significant Inboard Lower Tertiary oil resources”, said James H. Painter, Executive Vice President, Gulf of Mexico. “We look forward to providing additional information regarding Shenandoah’s resource potential and reservoir quality once the operator has completed well evaluation operations.”
“It is particularly gratifying to share the encouraging results of the Shenandoah appraisal well so soon after announcing our North Platte Inboard Lower Tertiary discovery”, said James W. Farnsworth, Chief Exploration Officer. “As a result of Cobalt being an early mover in the Inboard Lower Tertiary, we have developed a substantial acreage position in this play. This deep inventory offers Cobalt the opportunity to build on our recent success at North Platte and now Shenandoah by testing other large prospects in our portfolio.”

Cobalt holds a 20 percent working interest in Shenandoah. Co-owners in Shenandoah include Anadarko Petroleum Corporation, as operator (30 percent working interest), ConocoPhillips (30 percent working interest), Venari Resources LLC (10 percent working interest) and Marathon Oil Company (10 percent working interest). Cobalt has an average working interest of over 45% in ten prospects in the Inboard Lower Tertiary trend in the deepwater Gulf of Mexico and is currently drilling the Ardennes #1 exploratory well. Immediately following Ardennes #1, Cobalt will commence drilling the Aegean #1 exploratory well.
Cobalt also continues to ramp-up its Pre-salt program in West Africa in 2013, including a 2 rig, 4 well program in Angola and the drilling of the first deepwater Pre-salt well in Gabon. “While a great deal of attention is being paid to our planned initial test well on the massive Lontra prospect, every well we drill this year in Angola and Gabon will be significant. Each has the potential to be as large as, or larger than our 2012 Cameia discovery”, said James W. Farnsworth.
