NEW YORK, December 9, 2015, Tesoro Corporation (NYSE:TSO) (“Tesoro”) will host its annual Analyst and Investor Day today to outline its strategic initiatives, growth plans and detailed financial objectives.

"Tesoro has a proven track record of delivering on our commitments. We are on track to report record results for 2015. Further, we expect $400 million to $500 million of business improvements in 2016,” said Greg Goff, Tesoro Chairman, President and CEO. “By focusing on our strategic priorities, business improvements and growth in our logistics and marketing businesses, we expect to deliver $3.5 billion to $4.0 billion of EBITDA in 2018.”

Driving Refining Excellence and New Business Investments

Keith Casey, Executive Vice President of Operations, will outline Tesoro’s competitive refining system which has a track record of capturing gross margins through strong operational excellence and strategic business improvements. “Our refining portfolio has a 97 percent availability rate, which is world-class performance,” said Casey. “Through our operational excellence, disciplined capital investments and improved yield flexibility, we expect to deliver approximately $200 million of business improvements annually through 2018.”

In addition, Casey will review Tesoro’s progress on the execution of four strategic business investments. These projects include the Los Angeles Refinery Integration and Compliance Project, Vancouver Energy, West Coast Mixed Xylenes and the Anacortes Isomerization Project. These projects are expected to contribute approximately $50 million to $100 million of EBITDA in 2016-2018 and $350 million of annualized EBITDA by the end of 2018.

Driving Growth in Logistics

Phil Anderson, President of Tesoro Logistics, will provide an overview of Tesoro's distinctive strategy to continue to grow the logistics business. “Tesoro Logistics has become a leading provider of logistics services to oil and gas producers and refining and marketing companies in our strategic footprint,” said Anderson. “We have a clear path to deliver $1 billion in EBITDA in 2017.”

Anderson will outline Tesoro’s growth plans for 2016-2018 to drive value creation through organic investments, drop downs and strategic acquisitions.

Creating Value through Marketing

CJ Warner, Tesoro’s Executive Vice President of Strategy and Business Development, will review the progress made in growing Tesoro’s marketing business and outline the forward strategy for growth. “We expect to grow marketing into a $1 billion EBITDA business by 2018,” said Warner. “We will achieve this by delivering $150 million to $200 million of organic growth and business improvements, and through acquisitions which should contribute an additional $200 million to $300 million of EBITDA.”

We remain committed to deploying this cash in a balanced and disciplined manner that creates substantial shareholder value,” said Sterin.
