Tesoro Boosts Fuel Supply Position in Nevada

SAN ANTONIO, Texas, January 7, 2016 - Tesoro Corporation TSO, through its affiliate Tesoro Refining & Marketing Company LLC, has signed a strategic supply agreement with an affiliate of Anabi Oil Corporation ("Anabi") to sell fuel at 55 high volume retail stations in the greater Las Vegas, Nevada area that Anabi recently acquired. 

The agreement allows Tesoro to increase its fuel sales in the Las Vegas region and strengthen the presence of the ARCO® and Mobil® brands. Anabi's newly-acquired retail network is complimentary to Tesoro's existing network of 50 ARCO and Mobil branded locations in greater Las Vegas. This region is strategic for Tesoro as it provides supply flexibility from Tesoro's Los Angeles and Salt Lake City refineries and establishes a platform for the continued expansion of the ARCO and Mobil brands.

This supply agreement is consistent with Tesoro's integrated business model and strategy to strengthen its fuel marketing business, while further ensuring placement for finished products from its refining business.

Sam Anabi, President of Anabi Oil Corporation, said, "This will strengthen our network, and Las Vegas is a natural extension of the Southern California assets we currently hold. Tesoro is a strategic and valuable partner to Anabi Oil Corporation, and we look forward to a long relationship with Tesoro."

Claude Moreau, Senior Vice President of Marketing for Tesoro, said, "We are very pleased to  add these 55 high-quality locations to our existing branded portfolio in Las Vegas and to further grow our business."

Supply to the 55 retail stations in Las Vegas commenced mid-December, 2015.
