DEVON ENERGY REPORTS 2009 FINANCIAL RESULTS, RECORD PRODUCTION AND RECORD PROVED RESERVES

OKLAHOMA CITY — February 17, 2010 — Devon Energy Corporation (NYSE:DVN) today reported 2009 full-year and fourth-quarter financial results. The company also reported that its 2009 full-year oil and gas production from continuing operations reached an all-time high. In addition, Devon reported record-high proved oil and natural gas reserves at December 31, 2009. Production and changes to proved reserves are discussed in more detail later in this report.

For the year ended December 31, 2009, Devon reported a net loss of $2.5 billion, or $5.58 per common share ($5.58 per diluted common share). Devon’s 2009 financial results were impacted by certain items securities analysts typically exclude from their published estimates. The most significant of these items was a $4.2 billion after-tax reduction of the carrying value of oil and gas properties recorded in the first quarter of 2009. This was the result of a non-cash, full-cost ceiling adjustment. The charge resulted from application of the ceiling test as prescribed by the Securities and Exchange Commission for companies that follow the full-cost method of accounting.

Excluding the reduction of carrying value of oil and gas properties and other adjusting items, Devon earned $1.8 billion or $4.03 per diluted common share in 2009. The adjusting items are discussed in more detail later in this news release.

For the year ended December 31, 2008, Devon reported a net loss of $2.1 billion, or $4.85 per common share ($4.85 per diluted common share). The company’s 2008 financial results included a $7.1 billion non-cash, after-tax reduction in the carrying value of oil and gas properties.

Devon reported net earnings of $667 million, or $1.50 per common share ($1.49 per diluted common share), for the quarter ended December 31, 2009. Excluding adjusting items, the company earned $713 million, or $1.60 per diluted common share in the fourth quarter of 2009.

For the quarter ended December 31, 2008, Devon reported a net loss of $6.8 billion or, $15.42 per common share ($15.42 per diluted common share).

North American Onshore Proved Reserves at Record 2.6 Billion Boe;

Drill-Bit Reserve Additions More than Double Record Production

“2009 was a pivotal year for Devon as we began repositioning the company to focus entirely on our high-return, North American onshore natural gas and oil portfolio,” commented J. Larry Nichols, chairman and chief executive officer. “We grew North American onshore production by more than six percent in 2009 and replaced more than twice our production with the drill bit at very attractive costs. We expect to receive after-tax proceeds of $4.5 billion to $7.5 billion as we divest our offshore and international properties this year. This will further strengthen our rock-solid balance sheet and enable us to accelerate growth across our U.S. and Canadian asset base.”

In accordance with accounting standards, Devon’s year-end reserve reporting pertains to the company’s continuing operations, which include its Gulf of Mexico properties. Following is a discussion of proved reserves pertaining only to Devon’s North American onshore assets.

Devon increased North American onshore estimated proved reserves by 20 percent to a record 2,641 million oil-equivalent barrels (Boe) at December 31, 2009. The company added 669 million Boe to its North American onshore proved reserves from all sources. Costs incurred applicable to North American onshore properties were $3.3 billion.

Successful drilling (extensions, discoveries and performance revisions) accounted for 492 million Boe of North American onshore proved reserve additions. The company invested $3.2 billion of associated drill-bit capital during the year. Revisions related to changes in oil, natural gas and natural gas liquids prices increased 2009 North American onshore proved reserves by 176 million Boe.

North American onshore oil and gas production increased more than six percent to 220 million Boe in 2009. The reserve life index (proved reserves divided by annual production) for the North American onshore properties is approximately 12 years.

Proved developed reserves of 1,869 million Boe at December 31, 2009, represented 71 percent of total North American onshore proved reserves. Proved undeveloped reserves were 29 percent of the total. Year-end North American onshore proved reserves included 653 million barrels of crude oil, 9.4 trillion cubic feet of natural gas and 419 million barrels of natural gas liquids.

Divestitures Make Way for North American Onshore Growth

The company plans to direct the proceeds of the divestitures of its Gulf of Mexico and international properties to its U.S. and Canadian onshore operations and to retire debt. In accordance with accounting standards, Devon has reclassified the assets, liabilities and results of its international operations as discontinued operations for all accounting periods presented in this release. Although revenues and expenses for prior periods were reclassified, there was no impact upon previously reported net earnings. Included with the financial information that follows are tables of revenues, expenses, production, proved reserves and costs incurred and the amounts reclassified as discontinued operations for each period presented.

In spite of Devon’s plans to divest its Gulf of Mexico assets, these properties do not qualify as discontinued operations under accounting standards. However, information is provided in this release

that will enable the reader to isolate certain results of the company’s North American onshore operations.

Shale Gas Development and Jackfish Ramp-up Led 2009 Operating Highlights

Devon drilled 1,135 wells in 2009 applicable to its continuing operations with a 99 percent success rate. Following are operational highlights and updates for selected exploration and development projects:

•		The company drilled 336 wells in the Barnett Shale field in north Texas in 2009, bringing its total producing wells in the field to almost 4,200 at year end. Devon exited 2009 with net Barnett Shale production at just over 1 billion cubic feet of natural gas equivalent per day. The company drilled its 2,000th horizontal well in the field in early 2010 and is currently running 16 operated drilling rigs. Devon expects to drill 370 total Barnett Shale wells during the year.
•		Devon drilled 47 successful wells in the Cana-Woodford Shale in western Oklahoma in 2009. During 2009 the company increased its net production from this important new shale-gas resource to an average of 39 million cubic feet of gas equivalent per day. Devon has increased its lease position in the Cana-Woodford Shale to 118,000 net acres and expects to drill approximately 85 wells in the field in 2010.
•		The company drilled eight Haynesville Shale wells in the greater Carthage area of east Texas in 2009. These wells have significantly de-risked Devon’s 110,000 net Haynesville Shale acres in the Carthage area. The company expects to recover up to four trillion cubic feet equivalent of natural gas from its Carthage area Haynesville acreage.
•		In Canada, Devon’s 100-percent owned Jackfish oil sands project in Alberta was operational throughout 2009. As measured by production per well and steam-oil ratio, Jackfish is one of Canada’s most commercially successful steam-assisted gravity drainage (SAGD) projects. In late 2009, Jackfish production reached 33,700 barrels of oil per day. The addition of four more producing wells is expected to push production to the facility’s capacity of 35,000 barrels per day in early 2010.
•		Construction continued throughout 2009 on a second phase of the Jackfish SAGD project. Jackfish 2 is also sized to produce 35,000 barrels of oil per day and will commence operations in 2011. Devon expects to file a regulatory application for a third phase of the project in the third quarter of 2010.
•		Offshore Brazil, Devon participated in two significant deepwater discoveries in 2009. The Devon-operated Itaipu exploratory discovery followed a successful appraisal of the 2008 Wahoo discovery. Both Itaipu and Wahoo are pre-salt prospects located in the Campos Basin. Devon plans to divest its Brazilian assets along with all of its other international properties in 2010. The Itaipu and Wahoo discoveries significantly enhance the value of the company’s international assets to prospective buyers.

Continuing Operations Show Strong Production Growth

Combined oil, gas and natural gas liquids production from continuing operations averaged 639 thousand Boe per day in 2009. This compares with 2008 average daily production of 610 thousand Boe per day.

Sharp declines in the average prices of oil, gas and natural gas liquids led to a 48 percent reduction in combined sales from continuing operations. Comparable sales for the years 2009 and 2008 were $6.1 billion and $11.7 billion, respectively. Furthermore, marketing and midstream operating profit decreased 25 percent to $512 million in 2009, reflecting lower prices for natural gas and natural gas liquids.

Cash Flow Totals $4.7 Billion

Cash flow before balance sheet changes decreased 50 percent to $4.7 billion in 2009. During the year Devon funded $5.1 billion of capital expenditures and paid $284 million in dividends utilizing cash flow and short-term borrowing. In spite of the increase in short-term borrowing, Devon’s balance sheet remains strong with a ratio of net debt to adjusted capitalization of 29 percent. Reconciliations of cash flow before balance sheet changes, net debt and adjusted capitalization, which are non-GAAP measures, are provided in this release.

Items Excluded from Published Earnings Estimates

Devon’s reported net earnings include items of income and expense that are typically excluded by securities analysts in their published estimates of the company’s financial results. These items and their effects upon reported earnings for the full year and fourth quarter of 2009 were as follows:

Items affecting continuing operations:

•		A change in the fair value of oil and natural gas derivative instruments decreased full-year earnings by $121 million pre-tax ($77 million after tax) and an unrealized gain increased fourth-quarter earnings by $48 million pre-tax ($31 million after tax).
•		A change in fair value of other financial instruments increased full-year earnings by $66 million pre-tax ($42 million after tax) and increased fourth-quarter earnings by $81 million pre-tax ($52 million after tax).
•		Severance and restructuring costs decreased full-year earnings by $128 million pre-tax ($82 million after tax) and decreased fourth-quarter earnings by $105 million pre-tax ($67 million after tax).
•		A reduction of the carrying value of oil and gas properties decreased full-year earnings by $6.4 billion pre-tax ($4.1 billion after tax).
•		U.S. income taxes on foreign earnings now expected to be repatriated to the U.S. decreased full-year and fourth-quarter earnings by $55 million.
•		Income tax accrual adjustments increased full-year earnings by $59 million.

Items affecting discontinued operations:

•		A post-closing adjustment from the divestiture of West African assets in 2008 resulted in a full-year gain of $16 million pre-tax ($16 million after tax).
•		Severance and restructuring costs decreased full-year earnings by $57 million pre-tax ($37 million after tax) and decreased fourth-quarter earnings by $48 million pre-tax ($31 million after tax).
•		A reduction of the carrying value of oil and gas properties decreased full-year earnings by $108 million pre-tax ($105 million after tax).
•		Income tax benefits related to unsuccessful international drilling increased full-year earnings by $22 million.
•		The decision to divest all international assets generated financial benefits that increased full-year and fourth-quarter earnings by $37 million pre-tax ($24 million after tax).

The following tables summarize the full-year and fourth-quarter effects of these items on 2009 earnings, income taxes and cash flow.
