FINANCIAL AND OPERATIONAL INFORMATION

NON-GAAP FINANCIAL MEASURES

This press release includes non-GAAP financial measures. These non-GAAP measures are not alternatives to GAAP measures, and you should not consider these non-GAAP measures in isolation or as a substitute for analysis of our results as reported under GAAP. Below is additional disclosure regarding each of the non-GAAP measures used in this press release, including reconciliations to their most directly comparable GAAP measure.

CORE EARNINGS

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. Accordingly, the company also uses the measures of core earnings and core earnings per share attributable to Devon. Devon believes these non-GAAP measures facilitate comparisons of its performance to earnings estimates published by securities analysts. Devon also believes these non-GAAP measures can facilitate comparisons of its performance between periods and to the performance of its peers. The following table summarizes the effects of these items on first-quarter 2019 earnings.

(in millions, except per share amounts)	Quarter Ended March 31, 2019
	Before-tax			After-tax			Per Diluted Share
Net loss (GAAP)	$	(427	)	$	(317	)	$	(0.74	)
Adjustments:
Asset dispositions		(44	)		(34	)		(0.08	)
Asset and exploration impairments		1			1			—
Deferred tax asset valuation allowance		—			(18	)		(0.04	)
Fair value changes in financial instruments and foreign currency		635			484			1.12
Restructuring and transaction costs		54			42			0.10
Core earnings (Non-GAAP)	$	219		$	158		$	0.36

EBITDAX

Devon believes EBITDAX provides information useful in assessing operating and financial performance across periods. Devon computes EBITDAX as net earnings from continuing operations before income tax expense; financing costs, net; exploration expenses; depreciation, depletion and amortization; asset impairments; asset disposition gains and losses; non-cash share-based compensation; non-cash valuation changes for derivatives and financial instruments; restructuring and transaction costs; accretion on discounted liabilities; and other items not related to normal operations. EBITDAX as defined by Devon may not be comparable to similarly titled measures used by other companies and should be considered in conjunction with net earnings from continuing operations.

(in millions)	Q1 2019			Q4 2018
Net earnings (loss) from continuing operations (GAAP)	$	(317	)	$	1,149
Financing costs, net		73			70
Income tax expense (benefit)		(110	)		335
Exploration expenses		13			44
Depreciation, depletion and amortization		459			423
Asset disposition gains		(44	)		(268	)
Share-based compensation		26			27
Derivative and financial instrument non-cash valuation changes		635			(1,209	)
Restructuring and transaction costs		54			9
Accretion on discounted liabilities and other		(10	)		40
EBITDAX (Non-GAAP)	$	779		$	620

NET DEBT

Devon defines net debt as debt less cash and cash equivalents. Devon believes that netting these sources of cash against debt provides a clearer picture of the future demands on cash from Devon to repay debt.

(in millions)	March 31, 2019
Total debt (GAAP)	$	5,786
Less cash and cash equivalents		(1,327	)
Net debt (Non-GAAP)	$	4,459
