MANAGEMENT COMMENTARY

THIRD QUARTER 2010 RESULTS

SM Energy posted net income for the third quarter of 2010 of $15.5 million, or $0.24 per diluted share. This compares to a net loss of ($4.4 million), or ($0.07) per diluted share, for the same period in 2009. Adjusted net income for the quarter was $20.0 million, or $0.31 per diluted share, versus adjusted net income of $14.7 million, or $0.23 per diluted share, for the third quarter of 2009. Adjusted net income excludes certain items that the Company believes affect the comparability of operating results. Items excluded are generally one-time items or are items whose timing and/or amount cannot be reasonably estimated. A summary of the adjustments made to arrive at adjusted net income is presented in the table below.

Operating cash flow increased to $130.1 million for the third quarter of 2010 from $99.9 million in the same period last year. Net cash provided by operating activities also increased to $148.2 million for the third quarter of 2010 from $111.3 million in the same period in 2009.

Adjusted net income and operating cash flow are non-GAAP financial measures - please refer to the respective reconciliation in the accompanying Financial Highlights section at the end of this release for additional information about these measures.

SM Energy reported quarterly production of 298.4 MMCFE/d, which was at the high end of the guidance range of 277 to 299 MMCFE/d. Production came in at the high end of guidance primarily due to strong results in the Company's Eagle Ford shale program. Sequentially equivalent production grew 8% from 276.4 MMCFE/d in the second quarter of 2010 driven by a 12% increase in oil production.

Revenues and other income for the current quarter were $226.9 million compared to $185.8 million for the same period in 2009. For the third quarter of 2010, the average equivalent price per MCFE, net of hedging, was $7.51 per MCFE, which is an increase of 9% from the $6.86 per MCFE realized in the comparable period in 2009. Average realized prices, inclusive of hedging activities, were $5.81 per Mcf and $64.28 per barrel in the third quarter of 2010, which is an increase of 17% and 3%, respectively, from the same period a year ago. SM Energy reports its gas volumes on a "wet gas" basis, meaning that revenue dollars associated with natural gas liquids ("NGLs") are reported within the Company's natural gas revenues.

Lease operating expense ("LOE") of $1.06 per MCFE in the third quarter of 2010 was below the Company's guidance of $1.20 to $1.25 per MCFE. Lease operating expense for the quarter represents an 18% decrease from the $1.30 per MCFE in the comparable period last year. Sequentially, LOE declined 8% or $0.09 per MCFE in the third quarter of 2010 from the preceding quarter. A decline in workover activity in the Rocky Mountain region resulting from the divestiture of non-core assets early in the year was a driver for the decline in LOE. LOE on a per MCFE basis is also being driven lower by higher production.

Transportation expense of $0.18 per MCFE in the third quarter of 2010 was below guidance of $0.21 to $0.23 per MCFE. The reported per unit expense decreased from $0.20 per MCFE for the comparable period in 2009. Sequentially, transportation expense was also down 10% from $0.20 per MCFE in the second quarter of 2010.

Production taxes on a per MCFE basis increased 15% from $0.34 to $0.39 between the third quarters of 2009 and 2010. The increase is a function of commodity price realizations, which on a pre-hedge basis were higher in the third quarter of 2010 compared to the same period last year. The Company's realized production tax rate for the third quarter was 5.4%, which was below the provided guidance of 7% of pre-hedge oil and natural gas revenue. The difference from guidance is related to severance tax holidays benefitting the Mid-Continent region in the third quarter of 2010.

Total general and administrative ("G&A") expense for the third quarter of 2010 was $0.96 per MCFE, which was below the guidance range of $1.04 to $1.10 per MCFE provided by the Company. Cash G&A expense was $0.61 per MCFE for the quarter, compared to a guidance range of $0.65 to $0.67 per MCFE. Non-cash G&A for the third quarter was $0.21 per MCFE versus a guidance range of $0.20 to $0.22 per MCFE. G&A related to cash payments from the Company's legacy Net Profits Plan ("NPP") program was $0.14 per MCFE in the quarter compared to a guidance range of $0.19 to $0.21 per MCFE.

Depletion and depreciation expense ("DD&A") was $3.05 per MCFE in the third quarter of 2010, which was within the Company's guidance range of $2.90 to $3.10 per MCFE. Sequentially, DD&A decreased 4% from $3.17 per MCFE in the second quarter of 2010. The Company's DD&A rate is impacted by a number of factors, including divestitures and the accounting treatment of assets held for sale.

In the third quarter of 2010, SM Energy recognized a pre-tax non-cash expense of $4.1 million as a result of an increase in the NPP liability. The NPP liability is a significant management estimate that is highly sensitive to a number of assumptions including future commodity prices, production rates, and operating costs. The last pool created under this legacy compensation plan was in 2007.

FINANCIAL POSITION AND LIQUIDITY

As of September 30, 2010, SM Energy had total long-term debt of $275.4 million. The balance on the Company's 3.50% Senior Convertible Notes was $273.4 million, net of debt discount, and the Company's long-term credit facility had a balance of $2.0 million. The Company's debt-to-book capitalization ratio was 19% as of the end of the quarter.

The borrowing base for the long-term credit facility was re-determined by SM Energy's bank group on September 21, 2010, and was increased from $900 million to $1.1 billion. The Company has a commitment amount of $678 million from the Company's bank group. SM Energy is in compliance with all of the covenants associated with this facility.

(1) Adjustments are shown net of tax using the effective income tax rate;
calculated by dividing the income tax benefit (expense) by income (loss) before
income

taxes as stated on the consolidated statement of operations. Effective income
tax rates for the three months ended September 30, 2010 and 2009, were 37.7% and

37.1% respectively. Effective income tax rates for the nine months ended
September 30, 2010 and 2009, were 37.7% and 38.0% respectively.

(2) The loss related to hurricanes is included within line item other expense on
the consolidated statements of operations.

(3) Adjusted net income excludes certain items that the Company believes affect
the comparability of operating results. Items excluded generally are one-time
items or are items whose timing and/or amount cannot be reasonably estimated.
These items include non-cash adjustments and impairments such as the change in
the Net Profits Plan liability, unrealized derivative (gain) loss, impairment of
proved properties, abandonment and impairment of unproved properties, impairment
of materials inventory, (gain) loss on divestiture activity, and loss related to
hurricanes. The non-GAAP measure of adjusted net income is presented because
management believes it provides useful additional information to investors for
analysis of SM Energy's fundamental business on a recurring basis. In addition,
management believes that adjusted net income is widely used by professional
research analysts and others in the valuation, comparison, and investment
recommendations of companies in the oil and gas exploration and production
industry, and many investors use the published research of industry research
analysts in making investment decisions. Adjusted net income should not be
considered in isolation or as a substitute for net income, income from
operations, cash provided by operating activities or other income,
profitability, cash flow, or liquidity measures prepared under GAAP. Since
adjusted net income excludes some, but not all, items that affect net income and
may vary among companies, the adjusted net income amounts presented may not be
comparable to similarly titled measures of other companies.

(4) Beginning in the third quarter of 2009 the Company changed its definition of
operating cash flow. Prior periods have been conformed to the current

definition and the change in the definition did not result in a material
variance to results under the prior definiton. Operating cash flow is computed
as net cash

provided by operating activities adjusted for changes in current assets and
liabilities and exploration, less exploratory dry hole expense, and

stock-based compensation expense included in exploration. The non-GAAP measure
of operating cash flow is presented because management believes that it

provides useful additional information to investors for analysis of SM Energy's
ability to internally generate funds for exploration, development, acquisitions,
and to

service debt. In addition, operating cash flow is widely used by professional
research analysts and others in the valuation, comparison, and investment

recommendations of companies in the oil and gas exploration and production
industry, and many investors use the published research of industry research
analysts

in making investment decisions. Operating cash flow should not be considered in
isolation or as a substitute for net income, income from operations, net cash
provided

by operating activities or other income, profitability, cash flow, or liquidity
measures prepared under GAAP. Since operating cash flow excludes some, but not
all

items that affect net income and net cash provided by operating activities and
may vary among companies, the operating cash flow amounts presented may not

be comparable to similarly titled measures of other companies. See the
consolidated statements of cash flows herein for more detailed cash flow
information.
