SUPERIOR ENERGY SERVICES ANNOUNCES

FOURTH QUARTER AND FULL YEAR 2016 RESULTS

Houston, February 21, 2017 – Superior Energy Services, Inc. (the “Company”) today announced a net loss from continuing operations for the fourth quarter of 2016 of $166.3 million, or $1.10 per share, on revenue of $354.4 million. This compares to a net loss from continuing operations of $113.9 million, or $0.75 per share for the third quarter of 2016, on revenue of $326.2 million and a net loss from continuing operations of $214.5 million, or $1.43 per share for the fourth quarter of 2015, on revenue of $545.2 million.

The Company recorded a pre-tax expense of $73.2 million in reduction in value of assets and other charges in the fourth quarter of 2016. These charges included a $36.0 million impairment of long-lived assets, a $20.8 million write-down of inventory and $16.4 million of restructuring costs. The resulting adjusted net loss from continuing operations for the fourth quarter of 2016 was $111.6 million, or $0.74 per share. This compares to an adjusted net loss from continuing operations of $110.9 million, or $0.73 per share for the third quarter of 2016, and an adjusted net loss from continuing operations of $61.3 million, or $0.41 per share for the fourth quarter of 2015.

For the year ended December 31, 2016, the Company’s net loss from continuing operations was $833.3 million, or $5.50 per share, on revenue of $1,450.0 million as compared with a net loss from continuing operations of $1,807.8 million, or $12.02 per share, on revenue of $2,774.6 million for the year ended December 31, 2015.

“Our industry continued to transition toward recovery in U.S. land markets during the fourth quarter,” said David Dunlap, President and CEO. “During the quarter, our customers gradually increased their activity levels and began to project a bias towards spending growth in 2017. Our activation of idle equipment began in the third quarter of 2016 and accelerated in the fourth quarter.

“Throughout the downturn, we conserved cash, retired debt, reduced our cost structure and positioned certain businesses to be responsive early in a recovery. In addition to the competitive advantages of responding early, the ongoing expense associated with reactivating stacked equipment that can return to service is expected to decrease over time and be concluded during the second quarter of 2017. The extended downturn our industry just experienced won’t reverse in one or two quarters, but it definitely seems that we have entered the early days of the next upcycle in U.S. land markets.

“Elsewhere, our businesses operating in the Gulf of Mexico and internationally held up relatively well sequentially despite continued low levels of customer activity. The forward outlook for recovery in these areas remains subdued with limited recovery expected to occur during 2017. Accordingly, we intend to deploy capital selectively and maintain our focus on service quality in these markets.

“Each phase of a cycle presents unique challenges and we believe we are entering a period in which our emphasis on field level reliability and execution will be increasingly valued and recognized by our customers to the benefit of our stakeholders.”

Fourth Quarter 2016 Geographic Breakdown

U.S. land revenue was $200.3 million in the fourth quarter of 2016, an 18% increase as compared with revenue of $170.2 million in the third quarter of 2016 and an 18% decrease compared to revenue of $243.5 million in the fourth quarter of 2015.

U.S. land revenue increased 17% sequentially to $17.7 million as land drilling activity increased throughout the quarter. Gulf of Mexico revenue increased 14% sequentially to $25.8 million and international revenue increased 18% sequentially to $25.8 million, primarily as a result of an increase in premium drill pipe rentals.

Onshore Completion and Workover Services Segment

Sequentially, greater than 75% of the revenue increase was due to higher pressure pumping utilization resulting from increased completion activity in the Permian basin.

During the quarter, the Company spent approximately $14.7 million related to capacity enhancement of its pressure pumping fleet, fleet start-up costs, and demobilization and relocation of equipment to the Permian basin following the shutdown of a facility in Pennsylvania. In total during the second half of 2016, the Company spent approximately $23.1 million on activities associated with expanding and reactivating pressure pumping capacity due to current and anticipated increases in current customer demand.

U.S. land revenue increased 4% sequentially to $20.0 million due to increased activity for coiled tubing and well testing.

U.S. land revenue increased 13% sequentially to $12.0 million as well control activity and completion tools and products orders increased.

International revenue decreased 14% to $17.9 million primarily due to lower well control activity.
