SUPERIOR ENERGY SERVICES ANNOUNCES

THIRD QUARTER 2015 RESULTS

Houston, October 28, 2015 – Superior Energy Services, Inc. (the “Company”) today announced an adjusted net loss from continuing operations for the third quarter of 2015 of $68.8 million, or $0.46 per share, excluding special items, on revenue of $601.4 million. This compares to an adjusted net loss from continuing operations of $47.4 million, or $0.31 per share, excluding special items, for the second quarter of 2015, on revenue of $710.8 million. Reported loss from continuing operations for the third quarter of 2015 was $816.6 million, or $5.42 per share.

The prolonged decline in market activity resulted in the Company reporting a pre-tax charge of $755.6 million for the reduction in value of assets, primarily related to an impairment of goodwill in its Onshore Completion and Workover Services segment. The Company also reported a pre-tax charge of $10.5 million for restructuring costs. Restructuring costs were primarily related to an extensive product line integration and reorganization which occurred during the third quarter.

“We continue to operate in an extremely challenging market environment as our customers reduce spending in response to this prolonged period of low commodity prices,” said David Dunlap, President and CEO.

“North American customer activity trended lower and continued pricing pressure was evident across all product lines throughout the quarter. We expect these trends to continue in the fourth quarter of 2015 and in to the next year as our customers face increased financial pressure resulting from low crude oil and natural gas prices as well as significantly lower levels of liquidity than they have enjoyed in recent years.

“We have taken a measured approach to managing this downturn, progressively taking steps to lower costs across all categories. Throughout the year we have re-aligned our headcount, wages and benefits to better reflect the environment we are in. Where appropriate, we have stacked and isolated idled equipment. Most recently, we have reorganized several of our businesses with operational and commercial similarities, significantly reducing their overhead costs. This reorganization also allows us to better package these services, offering our customers an opportunity to improve efficiencies, accomplish more with less and remain competitive in this challenging environment.

“We know that cyclical downturns eventually end and when they do, the most prepared organizations benefit greatly. We are intently focused on emerging from this downturn as a stronger organization that is better positioned to provide the service reliability and operational execution our customers have come to expect from us.”
