Solaris Oilfield Infrastructure Issues Operational Update and Schedules Third Quarter 2020 Results Conference Call

Solaris Oilfield Infrastructure, Inc. (NYSE:SOI) ("Solaris" or the "Company") announced today it believes US frac and Solaris' activity, as measured by fully utilized frac crews and proppant silo systems, respectively, will be up 60-70% in the third quarter of 2020 on average from second quarter 2020. This compares to the Company's previous expectation for a 35-45% increase.

"While we are encouraged by the strength of the rebound in completion activity and our system deployments in the third quarter, we also acknowledge that there is currently limited visibility into fourth quarter and 2021 as the US horizontal rig count has remained flat for some time." Solaris' Chairman and Chief Executive Officer Bill Zartler commented. "In the meantime, the Solaris team is focusing on what we can control ? ensuring our customers receive exceptional service and improving our offerings while continuing to run a lean and cash generative business."
