Liberty Oilfield Services Inc. (NYSE: LBRT; "Liberty" or the "Company") will host its 2020 Annual Meeting of Stockholders (the "Annual Meeting") virtually due to the public health impact of the coronavirus (COVID-19) pandemic and to prioritize the health and well-being of meeting participants.

The Annual Meeting will be held in a virtual-only format via live audio webcast at 9:00 a.m. Mountain Standard Time on April 21, 2020. Stockholders will not be able to attend the Annual Meeting in person. Stockholders at the close of business on the record date, February 24, 2020, are entitled to participate in the Annual Meeting.
