Regarding: Delek /Alon Merger Update
All,
We are currently making great strides toward the early summer transaction close date. Our integration teams continue to work well together and are looking forward to beginning work on the integration plans that have been developed once the transaction is closed.
We were impressed with the insightful and business oriented questions we received in the “Questions” mailboxes from the Alon and Delek teams. The primary questions were related to company compensation and benefits, employment status, and organizational structure and operations.
We know these questions are important to you and we are working diligently to provide you with a response via a Frequently Asked Questions (FAQ) document that we plan to communicate in the near future. We are committed to communicating as much information as possible when it becomes available and we are legally able to do so. Please look forward to seeing updates from me or our Communications Committee on these topics in the coming weeks.
If you have additional questions or topics you would like us to address, please continue to send your thoughts to questions@delekus.com. Thank you for your continued focus and dedication as we begin this next phase in our journey.
Uzi Yemin
Chairman, President, and CEO of Delek US Holdings, Inc.
