DK Employee Letter

Dear Delek Colleagues,

I hope you and your families are well. As we head into the second quarter, I wanted to provide an update on a few matters.

First, regarding CVR Energy, Inc.’s (“CVR”) investment in Delek. CVR is majority owned by Icahn Enterprises L.P., led by Carl Icahn who is known for taking stakes in companies to seek representation on Boards of Directors. While CVR is a competitor, it also owns an approximate 15% stake in our company and recently nominated three directors to stand for election to our Board of Directors at the 2021 Annual Meeting of Shareholders. In addition to nominating directors, CVR has publicly pushed Delek to make some strategic changes, most of which are actions that would not maximize value at this time such as closing refineries or selling retail.

As it relates to this matter with CVR, I want to be clear that the CVR director nominations have no impact on our employees, customers, or business. We are continuing to execute on our objectives to support our vision of creating long-term value through sustainable energy solutions. As a reminder, Delek's five strategic objectives set clear expectations for the path we set and the standards we expect:

Safety & Wellness Leadership

Achieving safety & wellness leadership means that we become nationally recognized as leaders in our industry for our commitment to sustaining safe work environments that help every employee feel and do their best. It means that you come to work every day knowing that you are valued and protected.

Reliability & Integrity

By focusing on reliability and integrity, we maximize the return on our investments. Our employees, customers and shareholders can count on us to operate every aspect of our business responsibly, which means the work you do every day is recognized across our industry as reputable and essential.

Systems & Processes

We are committed to becoming even more efficient by focusing on our systems and processes. We know there’s always room for improvement, and those improvements can make everyone’s job more clearly defined and valued.

Risk

As we continue to grow we want to cultivate a healthy appetite for risk. That means, when we make decisions, we’re going to identify what risks come with the potential for more success, and pursue them with care.

Increasing EBITDA

Increasing our profitability means that we become a more sustainable business that’s equipped for constant steady growth. It means that we can achieve both our short term and long term goals.

We have a small team of management navigating this matter. For all other Delek colleagues, your continued focus on our business and objectives will ensure that we remain successful, meet our goals, and deliver value to our customers and shareholders alike.

I also recognize that many of you own shares in Delek. As a result, you are likely to receive materials from both Delek and CVR related to the election of directors. If you are currently a Delek shareholder, we recommend you support Delek and vote “FOR” all of Delek’s director nominees on the WHITE proxy card and that you discard any gold proxy card received from CVR. Every vote is important – regardless of how many shares you own.

We expect both Delek and CVR to make further public statements leading up to our Annual Meeting in May, which could result in more attention on our business from the media or investors. Should you be contacted by members of the media or investors for comment, please refer these inquiries to Blake Fernandez, Senior Vice President of Investor Relations and Market Intelligence, at Blake.Fernandez@delekus.com or 615-224-1312.

We have great confidence in each of you and where we are headed, as well as in our Board of Directors. With your help and dedication, we will continue to execute on our strategic priorities and drive innovation to continue to position Delek for growth and value creation into the future.

Again, I appreciate your continued focus on your responsibilities. Thank you for your contributions to Delek and keep up the great work.

Uzi Yemin

Chairman, President, and CEO
