Solaris Oilfield Infrastructure Announces Kingfisher Contract Amendment

Solaris Oilfield Infrastructure, Inc. (NYSE:SOI) (“Solaris” or the “Company”) announced today an amendment to the contract with its primary customer at the Company’s transloading facility in Kingfisher, Oklahoma (the “Kingfisher Facility”). The amended contract (1) reduces the minimum contracted annual revenue to approximately $3.6 million beginning in March 2019, (2) shortens the initial term to December 31, 2020, (3) triggers a partial termination payment to Solaris of approximately $26.0 million, which was paid in cash during December 2018, and (4) allows the use of a portion of the previously dedicated storage and rail track for additional third-party customers’ use.

In addition, Solaris has secured a two-year commitment from this customer to be its exclusive provider of well site proppant storage in Oklahoma, Texas and New Mexico.

Management Commentary

Solaris Chairman and Chief Executive Officer Bill Zartler commented, “We are pleased to reach a mutually-beneficial agreement to accommodate the shifting needs of both our customer and the industry.”

Zartler continued, “While the industry shift to in-basin sand has lowered potential demand for many transload facilities, including Kingfisher, it has the opposite effect on our mobile proppant systems. In-basin sand logistics removes a storage buffer from the supply chain and relies heavily on trucking, which introduces increased volatility to the total supply chain. We help our customers manage that volatility through our market leading mobile proppant management systems which provide a highly reliable and large inventory buffer at the blender in a relatively small footprint. In addition, our integrated software solutions provide complete last mile supply chain visibility which facilitates enhanced logistics management.”
