Forward-Looking Statements Forward-Looking Statements This communication includes “forward-looking statements” as defined by the SEC. Such statements include those concerning strategic plans, Devon’s and WPX’s expectations and objectives for future operations, as well as other future events or conditions, and are often identified by use of the words and phrases such as “expects,” “believes,” “will,” “would,” “could,” “continue,” “may,” “aims,” “likely to be,” “intends,” “forecasts,” “projections,” “estimates,” “plans,” “expectations,” “targets,” “opportunities,” “potential,” “anticipates,” “outlook” and other similar terminology. All statements, other than statements of historical facts, included in this communication that address activities, events or developments that Devon or WPX expects, believes or anticipates will or may occur in the future are forward-looking statements. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond Devon’s and WPX’s control. Consequently, actual future results could differ materially from Devon’s and WPX’s expectations due to a number of factors, including, but not limited to: the risk that Devon’s and WPX’s businesses will not be integrated successfully; the risk that the cost savings, synergies and growth from the Proposed Transaction may not be fully realized or may take longer to realize than expected; the diversion of management time on transaction-related issues; the effect of future regulatory or legislative actions on the companies or the industries in which they operate, including the risk of new restrictions with respect to hydraulic fracturing or other development activities on Devon’s or WPX’s federal acreage or their other assets; the risk that the credit ratings of the combined company or its subsidiaries may be different from what the companies expect; the risk that Devon or WPX may be unable to obtain governmental and regulatory approvals required for the Proposed Transaction, or that required governmental and regulatory approvals may delay the Proposed Transaction or result in the imposition of conditions that could reduce the anticipated benefits from the Proposed Transaction or cause the parties to abandon the Proposed Transaction; the risk that a condition to closing of the Proposed Transaction may not be satisfied; the length of time necessary to consummate the Proposed Transaction, which may be longer than anticipated for various reasons; potential liability resulting from pending or future litigation; changes in the general economic environment, or social or political conditions, that could affect the businesses; the potential impact of the announcement or consummation of the Proposed Transaction on relationships with customers, suppliers, competitors, management and other employees; the ability to hire and retain key personnel; reliance on and integration of information technology systems; the risks associated with assumptions the parties make in connection with the parties’ critical accounting estimates and legal proceedings; the volatility of oil, gas and natural gas liquids (NGL) prices; uncertainties inherent in estimating oil, gas and NGL reserves; the impact of reduced demand for our products and products made from them due to governmental and societal actions taken in response to the COVID-19 pandemic; the uncertainties, costs and risks involved in Devon’s and WPX’s operations, including as a result of employee misconduct; natural disasters, pandemics, epidemics (including COVID-19 and any escalation or worsening thereof) or other public health conditions; counterparty credit risks; risks relating to Devon’s and WPX’s indebtedness; risks related to Devon’s and WPX’s hedging activities; competition for assets, materials, people and capital; regulatory restrictions, compliance costs and other risks relating to governmental regulation, including with respect to environmental matters; cyberattack risks; Devon’s and WPX’s limited control over third parties who operate some of their respective oil and gas properties; midstream capacity constraints and potential interruptions in production; the extent to which insurance covers any losses Devon or WPX may experience; risks related to investors attempting to effect change; general domestic and international economic and political conditions, including the impact of COVID-19; and changes in tax, environmental and other laws, including court rulings, applicable to Devon’s and WPX’s business. In addition to the foregoing, the COVID-19 pandemic and its related repercussions have created significant volatility, uncertainty and turmoil in the global economy and Devon’s and WPX’s industry. This turmoil has included an unprecedented supply-and-demand imbalance for oil and other commodities, resulting in a swift and material decline in commodity prices in early 2020. Devon’s and WPX’s future actual results could differ materially from the forward-looking statements in this communication due to the COVID-19 pandemic and related impacts, including, by, among other things: contributing to a sustained or further deterioration in commodity prices; causing takeaway capacity constraints for production, resulting in further production shut-ins and additional downward pressure on impacted regional pricing differentials; limiting Devon’s and WPX’s ability to access sources of capital due to disruptions in financial markets; increasing the risk of a downgrade from credit rating agencies; exacerbating counterparty credit risks and the risk of supply chain interruptions; and increasing the risk of operational disruptions due to social distancing measures and other changes to business practices. Additional information concerning other risk factors is also contained in Devon’s and WPX’s most recently filed Annual Reports on Form 10-K, subsequent Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other SEC filings. Many of these risks, uncertainties and assumptions are beyond Devon’s or WPX’s ability to control or predict. Because of these risks, uncertainties and assumptions, you should not place undue reliance on these forward-looking statements. Nothing in this communication is intended, or is to be construed, as a profit forecast or to be interpreted to mean that earnings per share of Devon or WPX for the current or any future financial years or those of the combined company will necessarily match or exceed the historical published earnings per share of Devon or WPX, as applicable. Neither Devon nor WPX gives any assurance (1) that either Devon or WPX will achieve their expectations, or (2) concerning any result or the timing thereof, in each case, with respect to the Proposed Transaction or any regulatory action, administrative proceedings, government investigations, litigation, warning letters, consent decree, cost reductions, business strategies, earnings or revenue trends or future financial results. All subsequent written and oral forward-looking statements concerning Devon, WPX, the Proposed Transaction, the combined company or other matters and attributable to Devon or WPX or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above. Devon and WPX assume no duty to update or revise their respective forward-looking statements based on new information, future events or otherwise.
