Laredo Petroleum Hosts Investor Meeting and Provides Update

Increases Second-Quarter 2016 Production Guidance

TULSA, OK - June 13, 2016 - Laredo Petroleum, Inc. (NYSE: LPI) (“Laredo” or the “Company”), will host an investor meeting today in Midland, TX to update current activities, including the successful application of the Earth Model to the Company’s drilling program and the positive impact of infrastructure investments on operating expenses.

Update Highlights

·Increased production guidance for second-quarter 2016 from a range of 3.8 - 4.1 million barrels of oil equivalent (“MMBOE”) to 4.1 - 4.3 MMBOE, an increase of 6% at the midpoint of the range

·Reduced unit lease operating expense guidance for the second quarter of 2016 from $4.75 - $5.75 per BOE to $4.50 - $5.25 per BOE, a decrease of 7% at the midpoint of the range

·Reduced well cost estimates for 10,000’ Upper and Middle Wolfcamp horizontal wells drilled on multi-well pads by more than 20% from year-end 2015 estimates, to $5.4 million for a standard completion and $6.3 million for optimized completions with 1,800 pounds of sand per foot

“Laredo continues to derive substantial benefits from the strategic data and infrastructure investments the Company views as fundamental to efficient resource development,” commented Randy A. Foutch, Chairman and Chief Executive Officer. “Laredo’s contiguous acreage base and vast, multi-zone resource potential facilitate technology, data and infrastructure investments that drive efficient development. The Earth Model is instrumental in designing completions that are producing well results more than 30% above their type curves. Production corridor investments are driving Laredo’s peer-leading unit operating expenses even lower and contribute to drilling and completions cost reductions that place the Company’s cost to drill wells among the lowest, if not the lowest, in the Midland Basin. The sustainable benefits Laredo is recognizing from the Earth Model and production corridors are expected to continue to positively impact the Company’s capital efficiency.”
