NEWS RELEASE

Contango Announces Exploration Discovery

AUGUST 22, 2013—HOUSTON, TX – Contango Oil & Gas Company (NYSE MKT:MCF) today announced an exploration discovery at its South Timbalier 17 prospect, located in State of Louisiana waters and operated by Contango Operators, Inc. (“COI”), a wholly-owned subsidiary of the Company.

The well was drilled to a total measured depth of approximately 11,400 feet and the wireline logs of the well indicate the presence of hydrocarbons. Estimated reserves and production rates will be dependent upon the liquids content of the formation, which will be better defined once we complete and test the well. We are proceeding with development, including securing production facilities. Estimated costs net to Contango to drill, complete and bring this well to full production status are $12.5 million.

Contango has a 75% working interest (53.25% net revenue interest) before payout of all costs, and a 59.3% working interest (42.1% net revenue interest) after payout.

Joseph J. Romano, Contango’s Chairman and Chief Executive Officer, said, “We are pleased to have our first offshore discovery this year and are eager to drill additional offshore wells in our inventory. Our exploration permits have been approved on three of our prospects, and we hope to spud our next well, Ship Shoal 255, before the end of the year.

“Our merger with Crimson Exploration, Inc. is on schedule, and we expect to complete and begin mailing our proxy material for the merger next week.”

Contango is a Houston-based, independent natural gas and oil company. The Company’s business is to explore, develop, produce and acquire natural gas and oil properties onshore and offshore in the shallow waters of the Gulf of Mexico.

Statements concerning oil and gas reserves also may be deemed to be forward looking statements in that they reflect estimates based on certain assumptions that the resources involved can be economically exploited. Forward-looking statements are based on current expectations, estimates and projections that involve a number of risks and uncertainties, which could cause actual results to differ materially from those, reflected in the statements. These risks include, but are not limited to: the risks of the oil and gas industry (for example, operational risks in exploring for, developing and producing crude oil and natural gas; risks and uncertainties involving geology of oil and gas deposits; the uncertainty of reserve estimates; the uncertainty of estimates and projections relating to

future production, costs and expenses; potential delays or changes in plans with respect to exploration or development projects or capital expenditures; health, safety and environmental risks and risks related to weather such as hurricanes and other natural disasters); uncertainties as to the availability and cost of financing; fluctuations in oil and gas prices; risks associated with derivative positions; inability to realize expected value from acquisitions, inability of our management team to execute its plans to meet its goals, shortages of drilling equipment, oil field personnel and services, unavailability of gathering systems, pipelines and processing facilities and the possibility that government policies may change or governmental approvals may be delayed or withheld. Additional information on these and other factors which could affect Contango’s operations or financial results are included in Contango’s other reports on file with the SEC. Investors are cautioned that any forward-looking statements are not guarantees of future performance and actual results or developments may differ materially from the projections in the forward-looking statements. Forward-looking statements are based on the estimates and opinions of management at the time the statements are made. Contango does not assume any obligation to update forward-looking statements should circumstances or management’s estimates or opinions change.

In addition, forward-looking statements are subject to risks, uncertainties, assumptions and other factors that are difficult to predict and that could cause actual results to vary materially from those expressed in or indicated by them. Factors that could cause actual results to differ materially include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of the Company’s merger agreement with Crimson Exploration, Inc., dated as of April 29, 2013 (the “Merger Agreement”); (2) the outcome of any legal proceedings that may be instituted against the Company and others following announcement of the Merger Agreement; (3) the inability to complete the merger due to the failure to satisfy the conditions to the merger, including obtaining the affirmative vote of at least a majority of the votes cast by the holders of the Company’s outstanding shares of common stock entitled to vote on the approval of issuance of shares of Company common stock; (4) risks that the proposed transaction disrupts current plans and operations and potential difficulties in employee and customer retention as a result of the merger; (5) the ability to recognize the benefits of the merger; (6) legislative, regulatory and economic developments; and (7) other factors described in the Company’s filings with the SEC. Many of the factors that will determine the outcome of the subject matter of this filing are beyond the Company’s ability to control or predict. The Company can give no assurance that the conditions to the merger will be satisfied. Except as required by law, the Company undertakes no obligation to revise or update any forward-looking statement, or to make any other forward-looking statements, whether as a result of new information, future events or otherwise.
