Devon and WPX merger update

Senior leaders from WPX and Devon have taken initial steps in the merger integration planning process. The integration team will include:

From time to time, the integration team will draw upon subject matter experts from both WPX and Devon. The team also is evaluating the services of merger integration experts that may provide additional resources, structure and support.    

A look at timing

Both companies have agreed that there will be no merger-related workforce reductions until after the first of the year.

This provides reassurance to employees and your families through the holidays, as well as some degree of certainty in an uncertain process.

That is also helpful to know even if the merger closes early in mid-December, which depends on a number of factors including regulatory and shareholder approvals.

It’s certainly possible that closing still won’t occur until early 2021. Just keep in mind that “closing” and “integrating” are very distinct things.

“Closing” is simply the date when the transaction is complete. “Integrating” is a process that stretches beyond a singular physical day on the calendar and can’t take place until after “closing.”

Until then, Devon and WPX will continue to operate as independent companies.

Initial org design

The future executive team has determined the new organizational structure and reporting relationships. The teams reporting to each leader are listed below. As integration planning continues, there may be additional changes to the structure:   

Specific leaders over each function, as well as plans for individual roles, will be communicated near or shortly after the merger closing.

It’s still going to take some time to get clarity around the future of your own role. And even if a role is eliminated after the first of the year, it’s entirely possible that you may be asked to support the integration period for a while. Thank you for your continued patience and professionalism.
