SM ENERGY PROVIDES FIRST QUARTER UPDATE AND

ANNOUNCES PARTICIPATION AT IPAA CONFERENCE

DENVER, CO March 21, 2019 - SM Energy Company (the “Company”) (NYSE: SM) today provides certain operational updates for the first quarter of 2019 and announces participation in an upcoming investor event.

The 25-well Merlin Maximus development located in the heart of the RockStar area is off to a successful start. All 25 wells were drilled and completed as planned and on budget. 24 of the 25 wells (one well intentionally shut-in to monitor sub-surface pressure) are on production as scheduled. While it is very early data, all wells are meeting or exceeding production expectations. The 25-well development includes nine Lower Spraberry, 11 Wolfcamp A and five Wolfcamp B wells located across a 1.1-by-2 mile development area. The wells have an average lateral length of 10,300 feet. Water production from the wells feeds into the Company’s recently constructed water management system, which transports produced water either to Company-operated disposal wells or to be recycled for new well completions.

“This is a tremendous project that includes co-development of three intervals while applying and testing some of the latest science and technologies for landing zones and completions. It is absolutely a testament to our ability to execute and to our exceptional operations team,” commented President and Chief Executive Officer Jay Ottoson. “Success in the co-development of multiple intervals with larger development pads sets the stage for continued improvement in capital efficiency in the Permian Basin as we seek to optimize returns.”

Additional first quarter 2019 updates include:

The third-party gas processing facility that was off-line due to a force majeure event re-started service at the end of February and is expected to be at normal capacity soon. The Company’s Permian Basin natural gas sales are continuing to be affected in March due to the slower than expected ramp up of the plant to full capacity. In addition, high winds in West Texas during the week of March 12^th caused electrical outages that disabled artificial lift installations on several wells and resulted in temporary production shut-ins. The Company reaffirms its first quarter production guidance range of 10.5-10.9 MMBoe despite these temporary, unanticipated impacts to sales volumes in March totaling (0.2) MMBoe.

Permian Basin oil differentials to Cushing WTI improved significantly since the start of the year. The Company’s pre-hedge net differential improved from approximately ($9) per Bbl in January to approximately ($6) per Bbl in February and is expected to be further improved in March. Approximately 50%+ of expected first quarter Permian oil volumes have hedges in place for the Midland differential that average $4.44 per Bbl.
