National Energy Services Reunited Corp. Reports First Quarter Financial Results

HOUSTON, June 3, 2025 – 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”) region, today reported its financial results as of and for the three months ended March 31, 2025. 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, and 4 below for reconciliations of GAAP to non-GAAP financial measures. The Condensed Consolidated Balance Sheets, Condensed Consolidated Interim Statements of Operations, and Condensed Consolidated Interim Statements of Cash Flows are derived from the unaudited condensed consolidated interim financial statements present in our Period Report on Form 6-K as of and for the three months ended March 31, 2025.

Stefan Angeli, Chief Financial Officer commented “Despite seasonal slowdowns associated with the holy month of Ramadan and continued macroeconomic uncertainty, NESR delivered solid results in Q1 2025. Revenue reached $303.1 million, representing a 2.1% increase compared to Q1 2024, and as expected, declined sequentially from Q4 2024. Adjusted EBITDA for the quarter was $62.5 million, with a margin of 20.6%, while cash flow from operations totaled $20.5 million.

Owing to the strength of our recent financial results, we are pleased to report that our Net Debt to Adjusted EBITDA ratio remained below 1.0, ending the quarter at 0.93 as of March 31, 2025, a significant improvement from 1.30 at March 31, 2024. Adjusted EPS for Q1 2025 was $0.14, broadly in line with $0.15 reported in Q1 2024. Return on Capital Employed (ROCE) on a trailing twelve-month basis was 11.3%. Operational execution across the region remained strong throughout the quarter, underpinned by continued improved processes, streamlined procedures, and reinforced internal controls. These enhancements have transformed our back-office operations and played a significant role in driving our performance.

In spite of global economic headwinds, conditions in the MENA region remain supportive of growth, and NESR remains firmly focused on its core strategic priorities: delivering profitable revenue growth, enhancing execution efficiency, commercializing new technology, and improving debt reduction and working capital efficiency to support long-term financial performance. On behalf of management, I would like to express our sincere gratitude to our entire workforce for their outstanding efforts in delivering these results, and to our directors, shareholders, and banking partners for their continued trust and unwavering support. We believe the path forward holds significant opportunity, and we remain confident in our ability to deliver.”

Sherif Foda, Chairman and Chief Executive Officer, commented, “Firstly, I would like to express my sincere appreciation to our field teams for their unwavering commitment, exceptional service quality, and dedication to our valued customers during the quarter, especially in light of the holiday period and geopolitical headwinds in recent months. We take pride in operating within the strongest geographic region globally for upstream activity and despite recent declines in commodity prices, we remain confident in our continued growth trajectory. Much like our successful execution during the COVID-19 pandemic in 2020 and 2021, we are once again investing countercyclically, positioning ourselves for opportunities in the short, medium, and long term. With multiple recent contract awards across key countries, we anticipate solid performance in both 2025 and 2026. We are also accelerating the deployment of advanced technologies across our footprint and are especially encouraged by the momentum in our NEDA portfolio. This progress signals a major opportunity in unlocking value in the water and mineral sectors, an area we are truly excited about.”

Net Income and Adjusted Net Income Results

For the quarter ended March 31, 2025, the Company reported net income of $10.4 million, an increase of $0.4 million compared to the same period last year. This improvement was primarily driven by increased rig assignments in Saudi Arabia and higher contributions from the ROYA™ advanced directional drilling platform, partially offset by the seasonal slowdown in project activity during the holy month of Ramadan. Adjusted net income for the quarter ended March 31, 2025, was $13.0 million, which includes adjustments totaling $2.6 million (collectively, ‘Total Charges and Credits impacting Adjusted Net Income and Adjusted Diluted EPS’). These adjustments primarily relate to expenditures aimed at remediating the Company’s material weaknesses and impairment charges, somewhat counterbalanced by releases from litigation reserves and current expected credit loss provisions. 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 $0.11 of diluted EPS for the quarter ended March 31, 2025. Adjusted for the impact of Total Charges and Credits impacting Adjusted Net Income and Adjusted Diluted EPS, Adjusted Diluted EPS, a non-GAAP measure described in Table 1 below, for the quarter ended March 31, 2025, was $0.14.

Adjusted EBITDA Results

The Company generated Adjusted EBITDA of $62.5 million for the quarter ended March 31, 2025, representing a decrease of 2.7% year-over-year. Adjusted EBITDA includes adjustments totaling $2.6 million (referred to as ‘Total Charges and Credits impacting Adjusted EBITDA’), which represent components of the Total Charges and Credits impacting Adjusted Net Income and Adjusted Diluted EPS that are not related to interest, taxes, or depreciation and amortization. As referenced above, a detailed list of these adjusting items and the corresponding GAAP reconciliation is provided in Table 1. The Company reported the following financial results for the periods presented.

Balance Sheet

Cash and cash equivalents are $78.7 million as of March 31, 2025, compared to $108.0 million as of December 31, 2024.

Free cash flow, a non-GAAP measure, was negative $9.6 million for the three months ended March 31, 2025, compared to $31.2 million for the same period in 2024. The decline was primarily driven by seasonal increases in working capital during the holy month of Ramadan, mitigated in part by lower capital expenditures year-over-year.

As of March 31, 2025, total debt stood at $366.3 million, with $127.7 million classified as short-term, compared to $382.8 million and $128.5 million, respectively, as of December 31, 2024. Net Debt (a non-GAAP measure), defined as the sum of current installments of long-term debt, short-term borrowings, and long-term debt, less cash and cash equivalents, totaled $287.6 million at March 31, 2025, up from $274.9 million at year-end 2024. The increase in Net Debt was primarily due to a decrease in cash, despite long-term debt repayments made during the quarter. A reconciliation of the comparable GAAP measures to Net Debt is provided in Table 4 below, entitled “Reconciliation to Net Debt.”

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 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 also discusses Free Cash Flow reconciled to Operating Cash Flow.

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.
