SUPERIOR ENERGY SERVICES ANNOUNCES

FIRST QUARTER 2017 RESULTS

Houston, April 25, 2017 – Superior Energy Services, Inc. (the “Company”) today announced a net loss from continuing operations for the first quarter of 2017 of $89.7 million, or $0.59 per share, on revenue of $400.9 million. This compares to a net loss from continuing operations of $166.3 million, or $1.10 per share for the fourth quarter of 2016, on revenue of $354.4 million and a net loss from continuing operations of $84.5 million, or $0.56 per share for the first quarter of 2016, on revenue of $413.1 million.

David Dunlap, President and CEO, commented “The first quarter of 2017 marked a period of massive cyclical transition in US land markets. The land rig count growth of approximately 25% during the first quarter resulted in rapidly accelerating supply chain activation levels, particularly as it relates to completion related services. This led to our U.S. land revenue growing by 29% sequentially, driven by a 49% increase in pressure pumping revenue.

“Entering the quarter, a number of costs related to increasing activity levels continued to impede margin growth. These factors included significant increases in sand pricing, costs associated with reactivation of equipment and increased hiring and training costs. As the quarter progressed, we gained momentum in our conversations with customers which focused on balancing these higher costs with increased demand and activity levels.

“We exited the first quarter in a much more favorable position as it relates to these factors than when the quarter began. As rig count growth slows and equipment reactivation costs are fully absorbed, transitional inefficiency should be significantly diminished. These factors, in addition to reasonable service price increases, should put us on a path to acceptable margins.

“Outside of U.S. land markets, we are encouraged by the non-rig related project work we have in the Gulf of Mexico and we are favorably positioned to benefit from any increases in drilling activity. Internationally, activity levels and spending are lagging the U.S. land recovery. Our focus internationally remains on expanding into new markets and carefully monitoring investment levels in existing markets until they show signs of recovery.

“Crude oil prices are higher than they were a year ago at this time, our customers have committed to higher levels of spending and we have been proactive in preparing for market recovery. Despite the near-term noise associated with market transition, everything we are observing from a fundamental perspective is moving in the direction necessary to create a path to increased growth and profitability.”
