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

HOUSTON, August 4, 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 June 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, “The second quarter was another milestone in which we continued to outpace market growth and prepared for the long international upcycle. We are very proud to have published our inaugural ESG report (https://www.nesr.com/assets/NESR-2020-ESG-Report.pdf), which highlights our core values and demonstrates our strength as the true National Champion of MENA, with clear, positive impact to the communities and environments where we operate. We always strive to play a significant role in enabling our industry to continue to be the most reliable provider of energy to the world in a sustainable and responsible fashion, and I am excited for the opportunities our flagship water projects and newly formed ESG IMPACT Segment provide.”

Mr. Foda continued, “Separately, NESR successfully integrated the operations of the three oilfield service lines that we acquired from Action Energy Company W.L.L. (“Action”) in early May 2021.  The initial payment to Action was substantially funded by available cash from operations, and the transaction further solidifies our rapidly growing presence in Kuwait.”

Net Income Results

The Company had net income for the second quarter of 2021 totaling $7.8 million. Adjusted net income for the second quarter of 2021 is $12.8 million and includes adjustments totaling $5.0 million (collectively, “Total Charges and Credits”) mainly related to transaction costs related to mergers and acquisitions and restructuring activities. A complete list of the adjusting items and the associated reconciliation from GAAP has been provided in Table 1 below in the section entitled “Reconciliation of Net Income and Adjusted Net Income.”

The Company reported $0.08 of diluted earnings per share (“EPS”) for the second quarter of 2021. Adjusted for the impact of Total Charges and Credits, Adjusted Diluted EPS, a non-GAAP measure described in Table 1 below, for the second quarter of 2021 is $0.14.

Adjusted EBITDA Results

The Company produced Adjusted EBITDA of $53.6 million during the second quarter of 2021, growing 7% as compared to $50.2 million in the first quarter of 2021, and improving 3% as compared to $51.8 million in the second quarter of 2020. Second quarter 2021 Adjusted EBITDA includes adjustments for certain Total Charges and Credits (those not related to interest, taxes, and/or depreciation and amortization) of $5.0 million. The Company posted the following results for the periods presented.

Production Services Segment Results

The Production Services segment contributed $152.7 million to consolidated revenue for the second quarter of 2021, an improvement of 12% from $136.8 million in the first quarter of 2021, mainly due to increased hydraulic fracturing activities, and 10% from $139.0 million in the second quarter of 2020. Segment Adjusted EBITDA, a non-GAAP measure, increased to $40.8 million from $36.3 million in the first quarter of 2021, an improvement of 12%, and from $40.5 million in the second quarter of 2020, an increase of 1%. Segment Adjusted EBITDA margins were substantially flat on a sequential quarter basis. The Production Services segment posted the following results for the periods presented.

Drilling and Evaluation Services Segment Results

The Drilling and Evaluation (“D&E”) Services segment contributed $82.3 million to consolidated revenue for the second quarter of 2021. Segment Adjusted EBITDA, a non-GAAP measure, totaled $17.5 million in the second quarter of 2021, improving 10% from $15.8 million in the second quarter of 2020. Segment EBITDA margins declined on sequential quarter basis as a result of product mix between the drilling and evaluation businesses.

The D&E Services segment posted the following results for the periods presented.

Offsetting both the Production Services segment and D&E Services segment results were certain corporate costs, which are not allocated to segment operations.

Balance Sheet

Cash and cash equivalents are $66.1 million as of June 30, 2021, compared to $75.0 million as of December 31, 2020.

Total debt as of June 30, 2021 is $401.3 million with $113.8 million of such debt classified as short-term. Working capital for the Company totaled $131.6 million as of June 30, 2021. Free cash flow, a non-GAAP measure, for the second quarter of 2021 is $11.7 million. Net Debt (a non-GAAP measure), which is the sum of our recorded Current installments of long-term debt, Short-term borrowings, and Long-term debt less Cash and cash equivalents, totaled $335.2 million as of June 30, 2021 as compared to $323.5 million as of December 31, 2020 and $342.3 million as of June 30, 2020. Net Debt has increased since year-end primarily due to additional borrowing capacity provided by the Company’s lenders to fund growth in certain countries.

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.
