Quintana Energy Services Provides Preliminary Fourth Quarter 2018 Results

HOUSTON--(BUSINESS WIRE)--February 25, 2019--Quintana Energy Services Inc. (NYSE: QES) (“QES” or the “Company”) today announced preliminary fourth quarter 2018 results.

Fourth quarter 2018 revenue is expected to range between $158.1 million to $161.3 million, fourth quarter 2018 net loss is expected to range between $(1.8) million to $(1.5) million¹ and fourth quarter 2018 Adjusted EBITDA⁽¹⁾ is expected to range between $13.2 million to $14.5 million. In the fourth quarter, QES weathered a tough macro environment and is expecting to record a 6% sequential increase in revenue, a 31% sequential decrease in net loss and an 8% sequential increase in Adjusted EBITDA⁽²⁾.

Rogers Herndon, QES President and Chief Executive Officer, stated, “I’m pleased to report that revenue increased sequentially at three of our four segments despite the market headwinds experienced in the fourth quarter. The sequential increase in revenue was largely driven by increased utilization in our Directional Drilling segment, and increased utilization and stages pumped in our Pressure Pumping segment, offset by reduced pricing driven by market dynamics. The sequential decrease in net loss and increase in Adjusted EBITDA was largely driven by improved results in our Directional Drilling segment.

“Additionally, we deployed two incremental large diameter coiled tubing units and executed on our previously announced Wireline segment reorganization late in the fourth quarter and believe the benefits of this reorganization will prove out in the first quarter of 2019. We will discuss our results and market outlook in more detail when we release earnings on March 6, 2019.”

QES will release actual fourth quarter 2018 and full year financial results on March 6, 2019, after the market closes. The Company has scheduled a conference call to discuss its financial results on Thursday, March 7, 2019, at 9:00 a.m. Central Time (10:00 a.m. Eastern Time).

The information presented herein should not be considered a substitute for full unaudited financial statements for the three months ended December 31, 2018 once they become available and should not be regarded as a representation by the Company or its management as to its actual financial results for the three months ended December 31, 2018. The ranges for the preliminary estimated financial results described above constitute forward-looking statements.

Non-GAAP Financial Measures

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies.

Adjusted EBITDA is not a measure of net income or cash flows as determined in accordance with GAAP. We define Adjusted EBITDA as net income or (loss) plus income taxes, net interest expense, depreciation and amortization, impairment charges, net (gain) or loss on disposition of assets, stock based compensation, transaction expenses, rebranding expenses, settlement expenses, severance expenses and equipment standup expense.

We believe Adjusted EBITDA is useful because it allows us to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP, or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDA. Our computations of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies.

(2) Assuming midpoint of range.
