CGG Announces Second Quarter 2013 Results

Very Strong Second Quarter 2013 Excellent operational and financial performance High level of multi-client sales

PARIS, France – August 1 st 2013 – CGG (ISIN: 0000120164 – NYSE: CGG) announced today its non-audited second quarter 2013 consolidated results. All comparisons are made on a year-onyear basis with CGG 2012 results before the Fugro Geoscience acquisition.

Very strong quarter with Revenue up 24% and an EBIT at \$117 million corresponding to an EBIT at \$128 million not-including a \$11 million* negative non-recurring impact

• o Group Revenue at \$1.032 billion, up 24%
• o Group EBIT margin was 11% and 12% not-including the negative nonrecurring impact from the Fugro Geosciences transaction
• o Sustained EBIT margin at 28% for the Equipment division in line with forecasts
• o Acquisition division's EBIT margin at 5% with a sequential improvement in marine acquisition and with seasonal weak activity in land acquisition
• o Strong EBIT margin from Geology, Geophysics & Reservoir (GGR) division at 26%, notably driven by a high level of multi-client sales at \$190 million. 84% multi-client cash prefunding rate
• o Strong sequential increase in operating cash flow at \$204 million
• o Negative free cash flow at \$(43) million after payment of \$58 million in interest
• o Net income of \$36 million
• o Backlog at the end of June stood at \$1.3 billion

CGG CEO, Jean-Georges Malcor, commented:

"CGG, in its new configuration, delivered a very good operational and financial performance over the quarter. Two of our divisions, Equipment and Geology, Geophysics & Reservoir, both achieved high operating margins, confirming the strength of their businesses, positioning and operations. In the Acquisition Division, Marine results were driven by record utilization rates while Land registered a loss, mainly due to the low seasonal activity in North America and severe weather and security conditions in certain countries.

Looking forward to the end of 2013 and 2014, we remain confident about exploration & production spending levels of our clients. While the integration of Fugro's former activities is progressing well and is already bearing fruit, the reinforcement of CGG in the Geosciences is providing significant new long-term opportunities. In this context, we are confirming our annual objectives, with a second semester that we expect to be characterized by a very strong fourth quarter, especially for Sercel and multi-client."

^*This negative impact of \$(11)m linked to the Fugro Geoscience Acquisition comes in addition to the \$35m positive impact during the first quarter of 2013.

Post-closing events:

As part of the company's proactive management of its debt, CGG accelerated in July the refinancing of its credit facilities by extending the debt maturity periods:

• A five-year-\$200-million credit facility was signed with a 4.4% interest rate, notably to reimburse the 2013 tranche of our Fugro Vendor Loan
• The two existing \$289m Revolving Credit Facilities expiring in January 2014 were fully renewed with:
• o A-\$165-million US Revolving Credit Facility for a period of 3+1+1 year
• o A-\$325-million French Revolving Credit Facility for a period of three year with an option for five year
• CGG also sent an early redemption notice to repay \$125 million of the 9.5% 2016 High Yield Bond

Confirmation of our 2013 Financial Objectives

• 25% growth in revenue
• To address sustained demand in multi-client especially in Brazil, multi-client cash capex was revised up to \$400-\$450 million with a prefunding rate confirmed above 75%
• Industrial capex maintained around \$300-\$350 million
• Positive Free Cash Flow generation
• Return on Capital Employed improvement

Equipment division Total Revenue was \$254 million, down 11% compared to second the quarter of 2012 and up slightly sequentially. Marine equipment sales represented 48% of total revenue. Sales were strong in Eastern Europe, Asia and Russia. The commercial success of UNITE, Sercel's wireless land acquisition system, is confirmed with sales in North America and Latin America during the quarter. External sales were \$188 million, down 19% and internal sales represented 26% of total revenue.

Sercel successfully launched its new multi-sensor solid streamer, the Sentinel® MS streamer at the European seismic convention in June. It offers directional measurements for both cross-line and vertical wave fronts and delivers multi-sensor data sets for enhanced broadband imaging.

Equipment division EBITDAs was \$83 million, a margin of 33%.

Equipment division EBIT was \$71 million, a margin of 28%.

Acquisition

Acquisition division Total Revenue increased sharply to \$605 million, up 30% yearon-year and up 2% sequentially, due to an excellent operational performance by Marine acquisition. External revenue was \$477 million.

Marine Acquisition revenue increased sharply to \$511 million, up 53% year-onyear and 14% sequentially. Production was high this quarter for the whole fleet with record availability and production rates at 93% and 92%. 45% of the fleet was acquiring BroadSeisTM projects. A large part of the fleet was located in the North Sea where six vessels were in operation, four in the Gulf of Mexico and six in Asia. 21% of the fleet was dedicated to multi-client programs.

Land and Airborne Acquisition revenue totalled \$94 million, down 28% year-onyear and 35% sequentially. During this typically weak quarter, land crews operated in challenging safety and weather conditions. The Airborne organization should join CGG in early September.

Acquisition division EBITDAs was \$121 million, a margin of 20%.

Acquisition division EBIT was \$28 million, a margin of 5%. Marine acquisition continued to improve its operational and financial performance with a record utilization rate. The traditionally low level of land activity in the second quarter, due to the demobilization of the winter crews in North America, was impacted by difficult safety conditions in North Africa and in Egypt and by unfavorable climate conditions particularly in Oman and France.

Acquisition division Capital Employed was \$3.3 billion at the end of June 2013.

UNAUDITED ANALYSIS BY OPERATING SEGMENT

We previously reported our results on the basis of two operating segments: Geophysical Services and Geophysical Equipment. As a result of the acquisition of the Fugro's Geoscience Division, we changed our organization, as well as the way management measures our performance. Since February 1, 2013, we are organized in three Divisions with the following operating segments:

• Acquisition segment, which comprises:
• Marine acquisition: seismic data acquisition offshore undertaken by us on behalf of a specific client;
• Land and Airborne: other seismic data acquisition undertaken by us on behalf of a specific client;
• Geology, Geophysics & Reservoir ("GGR") segment which comprises:
• Multi-clients, basin data and Data Management: seismic and geological data undertaken by us and licensed to a number of clients on a non-exclusive basis and data management services;
• Imaging and Reservoir: processing and imaging of geophysical data and reservoir characterization.
• Equipment segment, which we conduct through Sercel, comprises our manufacturing and sales activities for seismic equipment used for data acquisition, both on land and marine.

Financial information by operating segment is reported in accordance with our internal reporting system and shows internal segment information that is used by the chief operating decision maker to manage and measure the performance.

We also changed our main performance indicator from operating income to earnings before interest and tax (―EBIT‖). We define EBIT as operating income plus our share of income in companies accounted for under the equity method. EBIT is used by management as performance indicator because it captures the contribution to our results of the significant businesses that we manage through our joint-ventures.

Prior period segment disclosure has been restated to reflect the new segments.
