The following is an excerpt from an earnings call held by Alon USA Partners, LP on November 9, 2017

Frederec Green — CEO & Executive VP of Alon USA Partners GP, LLC

“On November 8, 2017, Delek US and Alon Partners announced the execution of a definitive merger agreement, under which, Delek US will acquire all of the outstanding Alon Partners common units, representing limited partner interests, which Delek US or its affiliates do not already own in all stock for common units merger transaction. Delek US and its affiliates, currently own approximately 51 million common units of Alon Partners or approximately 81.6% of the outstanding units.

Under the terms of the merger agreement, the owners of the outstanding common units of Alon Partners that Delek US and its affiliates do not currently own, will receive a fixed exchange ratio of 0.49 Delek US shares for each common unit of Alon Partners. This implies a 5% premium to the 30-trading-day volume weighted average ratio through and including November 7, 2017, at 0.4666, and it represents a 2.9% premium to the ratio on November 7, 2017, which was the day before the parties announced this transaction. The transaction was approved by all voting members of the Board of Directors of the general partner of Alon Partners, upon the recommendation from its conflicts committee and by the Board of Directors of Delek US. This transaction is expected to close in the first quarter of 2018.

The approval and adoption of the merger agreement and the merger by Alon Partners, requires the approval by a majority of the outstanding Alon Partners common units. A subsidiary of Delek US, which owns a sufficient number of Alon Partners common units to approve the merger on behalf of all Alon Partners unitholders has executed a support agreement, in which it has irrevocably agreed to consent to the merger. The closing of merger is subject to customary closing conditions, including the effectiveness or registration statement on form S4, related to the issuance of new Delek US shares to Alon Partners public unitholders. No vote of the Delek US stockholders is required.

The combination with Delek US in an all equity transaction will provide our public unitholders with the opportunity to be part of a larger, more diverse and growing company. The variable distribution in LP model has not been rewarded by the equity markets and most have already been combined into or merged with C corps. For the simplified corporate structure and a diverse geographic base, the new Delek US will be well positioned to unlock additional value for shareholders.

Before I open the call for questions, I’d like to remind everyone that we are not able to comment on the pending transaction with Delek US. As a result, we will only be taking questions about ALDW operations.”
