Western Refining acquires ownership interests in Northern Tier Energy

Western Refining, Inc today announced that it has entered into a definitive agreement to acquire ACON Investments' and TPG's ownership interests in Northern Tier Energy LP for a total consideration of $775 million. ACON and TPG will receive the distribution on the common units that Western has acquired with respect to the quarter ended September 30, 2013. As a result of this transaction, Western owns Northern Tier Energy's general partner and 35,622,500 limited partner units, or approximately 38.7% of Northern Tier Energy. The balance of the limited partner units will remain publicly traded. The transaction was signed and closed on November 12, 2013.

Jeff Stevens, Chief Executive Officer and President of Western, said, "This investment further enhances our strategic goal of expanding our refining presence in areas with direct pipeline access to cost-advantaged crude oil resources. By adding these strategically aligned assets to our business portfolio, this transaction adds scale to our business and diversifies our operations by adding a new geographic region to our refining platform. Northern Tier Energy's St. Paul Park refinery is a very successful refinery with pipeline access to cost-advantaged crude oil and refined product regions that historically have generated strong product margins. The combined strength and scale of the two organizations will provide future growth opportunities for both companies over the long-term."

Hank Kuchta, Chief Executive Officer and President of Northern Tier Energy, said, "We are excited to welcome Western as a new strategic partner and investor that is committed, as much as we are, to Northern Tier Energy's long-term success. We thank ACON and TPG for their support over the past three years and we now look forward to working together with the Western Refining team to maximize value for all of our stakeholders."
