SM ENERGY: A TRANSFORMED PORTFOLIO FOCUSED ON TWO BASINS IN TEXAS MIDLAND BASIN ▪ ~82,500 net acres ▪ 7 Rigs / 3 Frac Crews EAGLE FORD ▪ ~165,000 net acres ~ 35 % ▪ 2 Rigs / 1 Frac Crew 4

RAPID IMPROVEMENT PRODUCTION UP, LEVERAGE DOWN Cash flow growth, up ~60% year over year (1) • Big Midland production growth • Rapid margin expansion; highest in 15 quarters Operational execution: New wells outperforming • Record RockStar wells; 24 new RockStar wells average 1,330 Boe/d peak 30-day IP rates (87% oil) • Increasing returns through efficiencies Significant reduction/restructuring of long-term debt • Redeemed $345MM 6.5% Senior Notes • Refinancing ~$480 MM in earlier maturities to 2027 $345 million ~$42/Boe Debt Reduction Permian Operating Margin (2) (1) 2Q18 / 2Q17 (2) 2Q18 Permian Basin regional production margin of $44.55 less corporate G&A per Boe. 5

MIDLAND BASIN EXECUTING ON OUR PLAN Midland Basin ~82,500 net acres • 38 net completions in 2Q18 - 30 in RockStar area RockStar • 7 rigs currently; expected to reduce to 6 in 3Q18 • 3 frac fleets operating at high efficiency • ~37 net completions expected in 3Q18; ~11 net completions expected in 4Q18 Sweetie Peck • Focusing on co-development of intervals 6

MIDLAND BASIN PRODUCTION GROWTH TRAJECTORY FASTER PACED D&C + WELL PERFORMANCE DRIVE PRODUCTION BEATS • Expected Permian production growth up ~90% 2018/2017 • Production outperformance drives margin growth • 2019 kicks off with 25-well Merlin-Maximus development expected to start 1Q19 Outperformance v. original plan Production (MBoe) 4Q16 1Q17 2Q17 3Q17 4Q17 1Q18 2Q18 3Q18e 4Q18e Outperformance v. original plan Note: 2018 estimated Permian Basin production by quarter based on current plan. 7
