National Energy Services Reunited Corp. Reports Third Quarter 2021 Financial Results

HOUSTON, November 3, 2021 – National Energy Services Reunited Corp. (“NESR” or the “Company”) (NASDAQ: NESR) (NASDAQ: NESRW), a national, industry-leading provider of integrated energy services in the Middle East and North Africa (“MENA”) and Asia Pacific regions, today reported its financial results for the quarter ended September 30, 2021. The Company posted the following results for the periods presented:

*The Company presents its financial results in accordance with generally accepted accounting principles in the United States of America (“GAAP”). However, management believes that using additional non-GAAP measures will enhance the evaluation of the profitability of the Company and its ongoing operations. Please see Tables 1, 2, 3, 4, 5 and 6 below for reconciliations of GAAP to non-GAAP financial measures.

Sherif Foda, Chairman of the Board and CEO of NESR said, “During the quarter, our team continued to prepare NESR for the emerging upcycle by generating strong free cash flow, securing multiple new contract awards, and executing a bevy of key technology partnerships. We are also extremely excited about the speed of development of our own disruptive drilling technologies, ESG Impact Segment and the progress we made this quarter. Despite the predicted temporary disruption during the quarter due mainly to the COVID-19 Delta variant and supply chain bottlenecks that delayed the startup of several projects, our thesis that MENA will be the main engine for growth and that the super cycle is materializing is more and more evident. As such, we continue to invest to ensure that we are the trusted and reliable partner to our customers. To support this growth, we finalized a milestone green debt refinancing this quarter that will provide enhanced liquidity and financial flexibility for continued growth.”

Mr. Foda continued, “I am very proud to report that during the FII, the world witnessed the leadership of Saudi Arabia with its Saudi Green Initiative, and our industry can play a vital role in lowering the total carbon footprint in the region and provide technologies for both the Blue and Green hydrogen. These technologies span not only in the carbon capture and storage space, but also in harnessing produced water, flared excess gas and waste heat in solving these challenges. We are very excited to be involved in several initiatives in this journey.”

The Company had net income for the third quarter of 2021 totaling $1.9 million.

NATIONAL ENERGY SERVICES REUNITED CORP. AND SUBSIDIARIES

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

(Unaudited)

(In US$ thousands except per share amounts)

The Company uses and presents certain key non-GAAP financial measures to evaluate its business and trends, measure performance, prepare financial projections and make strategic decisions. Included in this release are discussions of earnings before interest, income tax and depreciation and amortization adjusted for certain non-recurring and non-core expenses (“Adjusted EBITDA”), net income and diluted earnings per share (“EPS”) adjusted for certain non-recurring and non-core expenses (“Adjusted Net Income” and “Adjusted Diluted EPS,” respectively), as well as a reconciliation of these non-GAAP measures to operating income, net income, and diluted EPS, respectively, in accordance with GAAP. The Company also discusses the non-GAAP balance sheet measure of the sum of our recorded current installments of long-term debt, short-term borrowings, and long-term debt less cash and cash equivalents (“Net Debt”) in this release and provides a reconciliation to the GAAP measures of cash and cash equivalents, current installments of long-term debt, short-term borrowings, and long-term debt to Net Debt.

The Company believes that the presentation of Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted EPS provides useful information to investors in assessing its financial performance and results of operations as the Company’s board of directors, management and investors use Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted EPS to compare the Company’s operating performance on a consistent basis across periods by removing the effects of changes in capital structure (such as varying levels of interest expense), asset base (such as depreciation and amortization), items that do not impact the ongoing operations (transaction, integration, and startup costs) and items outside the control of its management team. Similarly, Net Debt is used by management as a liquidity measure used to illustrate the Company’s debt level absent variability in cash and cash equivalents, and the Company believes that the presentation of Net Debt provides useful information to investors in assessing its financial leverage. Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted EPS should not be considered as an alternative to operating income, net income, or diluted EPS, respectively, the most directly comparable GAAP financial measures. Net Debt also should not be considered as an alternative to GAAP measures of cash and cash equivalents, current installments of long-term debt, short-term borrowings, and long-term debt. Finally, Free Cash Flow is used by management as a liquidity measure to illustrate the Company’s ability to produce cash that is available to be distributed in a discretionary manner, after excluding investments in capital assets. Free Cash Flow should not be considered as an alternative to Net cash provided by (used in) operations or Net cash provided by (used in) investing activities, respectively, the most directly comparable GAAP financial measures. Non-GAAP financial measures have important limitations as analytical tools because they exclude some but not all items that affect the most directly comparable GAAP financial measure. You should not consider non-GAAP measures in isolation or as a substitute for an analysis of the Company’s results as reported under GAAP.

Information regularly reviewed by the chief operating decision maker for evaluating the financial performance of operating segments is focused on the timing of when the services are performed during a well’s lifecycle. Production Services are services performed during the production stage of a well’s lifecycle. Drilling and Evaluation Services are services performed during the pre-production stages of a well’s lifecycle. The Company believes that the presentation of Segment EBITDA provides useful information to investors in assessing its financial performance and results of operations.
