Forward-Looking Statements: This presentation and the oral statements made in connection herewith include “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. DTI’s actual results may differ from its expectations, estimates and projections, and, consequently, you should not rely on these forward-looking statements as predictions of future events. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “will,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward looking. These forward-looking statements include, but are not limited to, statements regarding DTI and its management team’s expectations, hopes, beliefs, intentions or strategies regarding the future. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. Forward-looking statements in this presentation may include, for example, statements about: (1) the demand for DTI’s products and services, which is influenced by the general level activity in the oil and gas industry; (2) DTI’s ability to retain its customers, particularly those that contribute to a large portion of its revenue; (3) DTI’s ability to employ and retain a sufficient number of skilled and qualified workers, including its key personnel; (4) DTI’s ability to market its services in a competitive industry; (5) DTI’s ability to execute, integrate and realize the benefits of acquisitions, and manage the resulting growth of its business; (6) potential liability for claims arising from damage or harm caused by the operation of DTI’s tools, or otherwise arising from the dangerous activities that are inherent in the oil and gas industry; (7) DTI’s ability to obtain additional capital; (8) potential political, regulatory, economic and social disruptions in the countries in which DTI conducts business, including changes in tax laws or tax rates; (9) DTI’s dependence on its information technology systems, in particular Customer Order Management Portal and Support System, for the efficient operation of DTI’s business; (10) DTI’s ability to comply with applicable laws, regulations and rules, including those related to the environment, greenhouse gases and climate change; (11) DTI’s ability to maintain an effective system of disclosure controls and internal control over financial reporting; (12) the potential for volatility in the market price of DTI’s common stock; (13) the impact of increased legal, accounting, administrative and other costs incurred as a public company, including the impact of possible shareholder litigation; (14) the potential for issuance of additional shares of DTI’s common stock or other equity securities; (15) DTI’s ability to maintain the listing of its common stock on Nasdaq; and (16) other risks and uncertainties separately provided to you and indicated from time to time described in DTI’s most recent Forms 10-K, 10-Q and 8-K filed with or furnished to the SEC. These forward-looking statements are based on DTI management's current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. DTI cautions that the foregoing list of factors is not exclusive and not to place undue reliance upon any forward-looking statements, including projections, which speak only as of the date made. You should also carefully consider the risks and uncertainties described and the information presented in DTI’s current annual report on Form 10-K filed March 14, 2025 and in subsequent current, quarterly and annual reports filed with or furnished to the SEC. These filings or potential filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements referred hereto. DTI undertakes no obligation to and accepts no obligation to release publicly any updates or revisions to any forward-looking statements or to reflect any change in its expectations or any change in events, conditions or circumstances on which any such statement is based, except as required by law. Industry, Market Data and Partnerships: In this presentation, DTI relies on and refers to certain information and statistics regarding the markets and industries in which DTI competes. Such information and statistics are based on management’s estimates and/or obtained from third-party sources, including reports by market research firms and company filings. While DTI believes such third-party information is reliable, there can be no assurance as to the accuracy or completeness of the indicated information. DTI has not independently verified the accuracy or completeness of the information provided by the third-party sources. This presentation contains descriptions of certain key business partnerships of DTI. These descriptions are based on DTI’s management team’s discussion with such counterparties, certain non-binding written agreements and the latest available information and estimates as of the date of this presentation. Use of Projections: This presentation contains projected financial information with respect to DTI. Such projected financial information constitutes forward-looking information, is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. Further, illustrative presentations are not necessarily based on management’s projections, estimates, expectations or targets but are presented for illustrative purposes only. DTI’s independent auditors have not audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this presentation, and, accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purpose of this presentation. The assumptions and estimates underlying such financial forecast information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties. See “Forward-Looking Statements” above. Actual results may differ materially from the results contemplated by the financial forecast information contained in this presentation, and the inclusion of such information in this presentation is not intended, and should not be regarded, as a representation by any person that the results reflected in such forecasts will be achieved. Further, the metrics referenced in this presentation regarding select aspects of DTI’s operations were selected by DTI on a subjective basis. Such metrics are provided solely for illustrative purposes to demonstrate elements of DTI’s business, are incomplete and are not necessarily indicative of DTI’s performance or future performance or overall operations. Any views expressed herein reflect the judgment of DTI as of the date of this presentation and may be subject to change if DTI becomes aware of any information, whether specific to a transaction or general (including changes in prevailing capital markets conditions), which may have an impact on any such views. You should not assume that any information in this overview is accurate as of any date other than the date hereof or as otherwise specified herein. There can be no assurance that historical trends will continue. Any investment in DTI’s common stock entails a high degree of risk. No assurance can be given that investors will receive a return on their capital, and investors could lose part or all of their investment. Non-GAAP Financial Measures: This presentation includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”), including, but not limited to: Adjusted EBITDA, Adjusted Net Income (Loss), Adjusted Free Cash Flow, and certain ratios and other metrics derived therefrom. Note that other companies may calculate these non-GAAP financial measures differently, and, therefore, such financial measures may not be directly comparable to similarly titled measures of other companies. Further, these non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing DTI’s financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income (loss), net cash (used in) provided by operating activities or other measures of profitability, liquidity or performance under GAAP. You should be aware that DTI’s presentation of these measures may not be comparable to similarly titled measures used by other companies. DTI believes these non-GAAP measures provide useful information to management and investors regarding certain financial and business trends relating to DTI’s results of operations. DTI believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in DTI, and in comparing DTI’s financial measures with those of other similar companies, many of which present similar non-GAAP financial measures to investors. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgment by management about which items of expense and income are excluded or included in determining these non-GAAP financial measures. Please refer to footnotes where presented on each page of this presentation or to the tables herein for a reconciliation of these measures to what DTI believes are the most directly comparable measure evaluated in accordance with GAAP. Reconciliation of historical non-GAAP measures to comparable GAAP measures are provided in the Appendix. This presentation also includes certain projections of non-GAAP financial measures. Reconciliation of these items to net income include gains or losses on sale or consolidation transactions, accelerated depreciation, impairment charges, gains or losses on retirement of debt, variations in effective tax rate and fluctuations in net working capital, which are difficult to predict and estimate and are primarily dependent on future events. Rounding: Certain monetary amounts, percentages and other figures included in this presentation have been subject to rounding adjustments. Certain other amounts that appear in this presentation may not sum due to rounding. Trademarks: This presentation contains trademarks, service marks, trade names and copyrights of DTI and other companies, which are the property of their respective owners. Solely for convenience, some of the trademarks, service marks, trade names and copyrights referred to in this presentation may be listed without the TM, SM, © or ® symbols, but DTI will assert, to the fullest extent under applicable law, the rights of the applicable owners, if any, to these trademarks, service marks, trade names and copyrights. Further, third-party logos included in this presentation may represent past or present vendors or suppliers of materials and/or products to DTI for use in connection with its business or may be provided simply for illustrative purposes only. Inclusion of such logos does not necessarily imply affiliation with or endorsement by such firms or businesses.
