The following letter was first sent to MarkWest Energy Partners, L.P.’s employees on July 13, 2015.
Today is a very exciting and transformative day for MarkWest. I am very pleased to announce that our board of directors has agreed to a combination with MPLX LP, a publicly traded Master Limited Partnership. MPLX is owned by Marathon Petroleum Corporation, a Fortune 25 company and is the 4th largest refiner in the nation and the largest in the Midwest and Northeast. This transaction is incredibly strategic and will allow us to move into our next phase of growth. This is an unparalleled opportunity as it combines the best of both the organic growth and the asset drop-down structure, as we continue to grow our core business and expand into downstream projects. Below are some of the key points of the transaction:
· Creates the 4th largest Master Limited Partnership with over $20 billion in market capitalization
· Merges our leading position in the Northeast with the largest refiner in the Northeast and Midwest
· Marathon Petroleum is an extremely strong sponsor with a substantial dropdown portfolio to support best-in-class distribution growth of the combined MLP
· Significant opportunity for synergistic projects
· Combined entity will have an investment grade profile and will lower our cost of capital
· MarkWest will:
· Operate as a stand-alone business within MPLX
· Continue with our entire team in place, which is critical to culture, integration and future success
· Maintain our existing Denver and regional offices
· Maintain our relationships with producers
· Remain the operator of our assets
· Play a leadership role in the development of new downstream projects with Marathon
Additionally, our executive team will continue in their same roles.
We appreciate that you have many questions. Additionally, we will have an employee conference call today (Monday, July 13th) at 8:30 MDT/10:30 EDT to provide you with further insight from me and Gary Heminger, President & CEO Marathon Petroleum Corporation. Instructions to access this conference call are included below. This is an exciting time for all of us in the MarkWest family. Our management team and I look forward to working with you as we embark on this next phase of our incredible journey.
