SUPERIOR ENERGY SERVICES ANNOUNCES

SECOND QUARTER 2015 RESULTS

Houston, July 30, 2015 – Superior Energy Services, Inc. (NYSE: SPN) (the “Company”) today announced an adjusted net loss from continuing operations for the second quarter of 2015 of $47.4 million, or a $0.31 loss per share, excluding special items, on revenue of $710.8 million. This compares to a net loss from continuing operations of $1.5 million, or $0.01 loss per share for the first quarter of 2015, on revenue of $917.2 million. Reported loss from continuing operations for the second quarter of 2015 was $775.1 million, or a $5.15 loss per share.

In light of the continuing downturn in the oil and gas industry, including the deteriorating demand for oilfield services, the Company reported a pre-tax charge of $807.6 million related to the reduction in value of assets during the second quarter of 2015. Of this charge, a pre-tax amount of $232.2 million related to the reduction in value of long-lived assets in the U.S. land and Mexico markets, primarily related to coiled tubing operations. The remaining amount, a pre-tax charge of $575.4 million, is an impairment of goodwill in the Company’s Production Services segment.

“During the second quarter we continued to emphasize cost reduction efforts as customer activity remained weak and equipment overcapacity weighed on service pricing,” said David Dunlap, President and CEO of the Company.

“Our efforts have resulted in general and administrative costs better than expectations and we expect to maintain these costs 10-15% below 2014 levels. Companywide headcount has been reduced by approximately 3,400 positions since the end of the 2014, representing 24% of our workforce. We have also reduced our cost per employee in our U.S. land related businesses by approximately 20% during the first half of 2015. We will continue to find ways, through compression or restructuring of our businesses, to reduce and eliminate costs with a goal of returning to profitability despite a challenging business environment.

“We also remain focused on operational excellence and customer service during this downturn. Although the average U.S. land rig count declined approximately 35% during the second quarter, our total revenue was down 22%, demonstrating the importance of product line and geographic diversity. We benefited from increased project related activity in the Gulf of Mexico and internationally and also performed well in Latin America across our service offerings there. Despite U.S. land markets showing extreme weakness, we are focused on maintaining our presence with existing customers and optimizing our operational and financial performance.

“Superior Energy is committed to improving performance and positioning itself for strong results when a recovery begins. We made prudent investments and built cash ahead of this downturn and as a result we will have flexibility ahead of a recovery when that occurs. For the time being, we will continue to pursue cost reductions, generate free cash flow and be prepared to capitalize on any opportunities a prolonged downturn can present.”

Second Quarter 2015 Geographic Breakdown

U.S. land revenue was $378.8 million in the second quarter of 2015, as compared with $721.3 million in the second quarter of 2014 and $576.3 million in the first quarter of 2015. Gulf of Mexico revenue was $162.5 million, as compared with $211.7 million in the second quarter of 2014 and $184.1 million in the first quarter of 2015.

Revenues for all major product lines of this segment were lower due to the continued low levels of activity in the oil and gas industry and continued pricing pressure.

All product lines in this segment were impacted negatively by a steep decline in the U.S. rig count and pricing pressure resulting from significant industry overcapacity.

Production Services Segment

The Production Services segment revenue in the second quarter of 2015 was $208.7 million, a 39% decrease from second quarter 2014 revenue of $343.9 million and a 17% decrease from first quarter 2015 revenue of $251.5 million.

U.S. land revenue decreased 31% sequentially during the quarter to $100.3 million, and Gulf of Mexico revenue decreased 13% sequentially to $22.3 million as customers continued to decrease spending and activity. International revenue increased 6% sequentially to $86.1 million due to increased levels of hydraulic workover, snubbing and electric line operations.

U.S. land revenue decreased 23% sequentially to $13.9 million as a result of lower levels of activity in the U.S. oil and gas industry. Gulf of Mexico revenue increased 7% sequentially to $76.8 million due primarily to increased project activity levels associated with favorable seasonal conditions. International revenue increased 43% sequentially to $36.3 million due primarily to higher completion tools revenue.

Non-GAAP Financial Measures

From time to time, management may publicly disclose certain “non-GAAP financial measures” in our earnings releases, financial presentations or earnings conference calls. These non-GAAP measures may include adjusted income (loss) from continuing operations, adjusted income (loss) from operations, EBITDA and free cash flow. The Company provides reconciliations to the nearest GAAP measure for these and other non-GAAP measures on a quarterly basis.

These non-GAAP measures are not in accordance with, or a substitute for, measures prepared in accordance with GAAP, and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. Non-GAAP measures have limitations in that they do not reflect all of the amounts associated with the Company’s results of operations that would be reflected in measures determined in accordance with GAAP.

These financial measures are provided to enhance investors’ overall understanding of the Company’s current financial performance. In addition, because the Company has reported certain non-GAAP measures in the past, the Company believes the inclusion of non-GAAP measures provides consistency in the Company’s financial reporting.
