SUPERIOR ENERGY SERVICES ANNOUNCES

FOURTH QUARTER AND FULL YEAR 2015 RESULTS

Houston, February 22, 2016 – Superior Energy Services, Inc. (the “Company”) today announced an adjusted net loss from continuing operations for the fourth quarter of 2015 of $61.3 million, or $0.41 per share, excluding special items, on revenue of $545.2 million. This compares to an adjusted net loss from continuing operations of $68.8 million, or $0.46 per share, excluding special items, for the third quarter of 2015, on revenue of $601.4 million, and net income from continuing operations of $73.4 million, or $0.48 per diluted share, for the fourth quarter of 2014, on revenue of $1,178.6 million. The reported loss from continuing operations for the fourth quarter of 2015 was $214.5 million, or $1.43 per share.

The Company recorded a pre-tax expense of $211.8 million in reduction in value of assets and other charges in the fourth quarter of 2015. These charges included a $175.6 million impairment of long-lived assets, primarily in the Technical Solutions segment and $36.2 million of restructuring costs related to a previously announced, extensive product line integration and reorganization. The Company recorded revenue from a contract termination fee of $22.9 million as a result of a customer discontinuing its arctic exploration program. This fee is included in the Company’s adjusted net loss from continuing operations.

For the year ended December 31, 2015, the Company’s net loss from continuing operations was $1,807.8 million, or $12.02 per share, on revenue of $2,774.6 million as compared with net income from continuing operations of $280.8 million, or $1.79 per diluted share, on revenue of $4,556.6 million for the year ended December 31, 2014.

“We continued to reduce our cost structure, increase our cash balances and focus on cash flow generation during the fourth quarter,” said David Dunlap, President and CEO. “Operationally, most product and service lines with exposure to onshore U.S. land markets continued to be impacted negatively by lower levels of activity and pricing pressure. In the Gulf of Mexico, project oriented work improved sequentially, driven by our hydraulic workover and snubbing and completion tools businesses. Internationally, increased coiled tubing utilization was offset by lower activity levels and pricing across the businesses in our drilling products and services segment.

“Although our long-term strategy of disciplined, geographic expansion remains unchanged, expectations for prolonged industry weakness compels us to emphasize our near-term priorities of cost reduction and cash preservation. Our efforts along these lines include identifying further opportunities internally for restructuring and reducing our 2016 capital plans significantly from 2015 levels. We expect 2016 capital expenditures to be within operating cash flows and concentrated on maintenance related activities.

“Additionally, we have renegotiated and extended our credit facility, which now matures in 2019 and includes covenants that are aligned with the current state of the industry. This extension pushes our nearest debt maturity to 2019. We do not anticipate needing any external capital to fund our operations and are prepared financially for a prolonged period of low levels of oil field activity.”

Fourth Quarter 2015 Geographic Breakdown

U.S. land revenue was $243.5 million in the fourth quarter of 2015, as compared with $338.3 million in the third quarter of 2015 and $805.2 million in the fourth quarter of 2014. Gulf of Mexico revenue, which includes a $22.9 million contract termination fee recorded during the quarter, was $169.7 million, as compared with $131.9 million in the third quarter of 2015 and $193.5 million in the fourth quarter of 2014. International revenue was $132.0 million, as compared with $131.2 million in the third quarter of 2015 and $179.9 million in the fourth quarter of 2014.

Drilling Products and Services Segment

The Drilling Products and Services segment revenue in the fourth quarter of 2015 was $111.7 million, a 13% decrease from third quarter 2015 revenue of $128.5 million and a 53% decrease from fourth quarter 2014 revenue of $234.9 million.

U.S. land revenue decreased 13% sequentially to $29.0 million, Gulf of Mexico revenue decreased 10% sequentially to $50.0 million and international revenue decreased 18% sequentially to $32.7 million. Lower revenues were driven by pricing pressure and lower utilization caused by further reductions of customer activity and spending.

Onshore Completion and Workover Services Segment

The Onshore Completion and Workover Services segment revenue in the fourth quarter of 2015 was $153.8 million, a 24% decrease from third quarter 2015 revenue of $202.9 million and a 67% decrease from fourth quarter 2014 revenue of $469.3 million. In addition to seasonal activity reductions, pricing and utilization continued to trend lower in this segment during the fourth quarter. During the fourth quarter, the Company suspended horizontal well fracturing operations in North Dakota. The Company’s cash return criteria were not being met in this region and it has elected to forego revenue opportunities there until the operating environment improves.

Production Services Segment

The Production Services segment revenue in the fourth quarter of 2015 was $135.6 million, a 17% decrease from third quarter 2015 revenue of $163.9 million and a 60% decrease from fourth quarter 2014 revenue of $342.0 million.

U.S. land revenue decreased 44% sequentially to $48.4 million due to lower activity levels across all service lines. Gulf of Mexico revenue increased 14% sequentially to $14.1 million and international revenue increased 12% sequentially to $73.1 million, primarily due to anticipated increases in hydraulic workover and snubbing activity.

Technical Solutions Segment

The Technical Solutions segment revenue in the fourth quarter of 2015 was $144.1 million, a 36% increase from third quarter 2015 revenue of $106.1 million and a 9% increase from fourth quarter 2014 revenue of $132.4 million.

U.S. land revenue decreased 23% sequentially to $12.3 million primarily due lower completion tools revenue which was offset partially by an increase in well control revenues. Gulf of Mexico revenue increased 65% sequentially to $105.6 million resulting from a contract termination fee of $22.9 million, increased completion tool revenue from deep water project sales and an increase in plug and abandonment activity. International revenue of $26.2 million was unchanged sequentially.

Credit Facility Amendment and Extension

The Company has amended and extended its credit facility. The amended agreement results in a $470.3 million credit facility which matures in 2019 and no longer has a term loan component. Financial covenants associated with this agreement are Net Debt to EBITDA and EBITDA to Interest coverage ratios and a minimum cash balance requirement. The Company filed a form 8-K earlier today relating to this agreement which contains additional details.
