Exhibit 99.1

QUINTANA ENERGY SERVICES INC. RECEIVES NOTICE FROM NYSE REGARDING CONTINUED LISTING REQUIREMENTS

HOUSTON – May 1, 2020 – Quintana Energy Services Inc. (“QES” or the “Company”) (NYSE: QES) announced today that, on April 27, 2020, the Company was notified by the New York Stock Exchange (“NYSE”) of its noncompliance with the NYSE’s continued listing standards because the average closing price of shares of its common stock had fallen below $1.00 per share over a period of 30 consecutive trading days, which is the minimum average closing price per share required to maintain continued listing on the NYSE. The Company’s Board of Directors is reviewing all available alternatives to return to compliance with the NYSE’s continued listing standards.

Under the NYSE’s rules, the Company has a period of six months following the receipt of the notice to regain compliance with the minimum share price requirement. However, due to unprecedented market-wide declines as a result of the spread of COVID-19, on April 21, 2020, the U.S. Securities and Exchange Commission (the “SEC”) approved the NYSE proposal to toll the cure period for the minimum share price requirement through June 30, 2020. Consequently, the Company has a period of six months, beginning on July 1, 2020, to regain compliance with the minimum share price requirement. To regain compliance, on the last trading day in any calendar month during the cure period, the Company’s common stock must have (i) a closing price of at least $1.00 per share and (ii) an average closing price of at least $1.00 per share over the 30 trading day period ending on the last trading day of such month. During the cure period, subject to the Company’s compliance with other NYSE continued listing requirements, shares of our common stock will continue to be traded on the NYSE under the symbol “QES” but will have an added designation of “.BC” to indicate that the Company currently is not in compliance with the NYSE’s continued listing requirements. If the Company is unable to regain compliance, the NYSE will initiate procedures to suspend and delist the Company’s common stock.

The NYSE notification does not affect our business operations or our SEC reporting requirements and does not result in a default under any of the Company’s material debt agreements.
