Disclaimer Important Information and Disclaimers This disclaimer applies to this document and the verbal or written comments of any person presenting it. This document, taken together with any such verbal or written comments, is referred to herein as the “Presentation.” Historical financial results presented in this Presentation as averages or in last twelve months or annualized forms are not necessarily indicative of results that may be expected for any future period. Cautionary Statement Regarding Forward-Looking Statements This Presentation contains forward-looking statements about Dril-Quip, Inc. (“Dril-Quip” or “DRQ”) and Innovex Downhole Solutions, Inc. (“Innovex,” “INVX,” “we” or “us”) and their industry that involve substantial risks and uncertainties. Forward-looking statements are not statements of historical fact but instead are based on Dril-Quip’s and Innovex’s present beliefs and assumptions and on information currently available to them. You can identify these forward-looking statements by the use of forward-looking words such as “outlook,” “believes,” “expects,” “potential,” “continues,” “may,” “will,” “should,” “could,” “seeks,” “approximately,” “predicts,” “intends,” “plans,” “estimates,” “anticipates,” “target,” “projects,” “contemplates” or the negative version of those words or other comparable words. Any forward-looking statements contained in this Presentation are based upon Dril-Quip’s and Innovex’s historical performance and on Dril-Quip’s and Innovex’s current plans, estimates and expectations in light of information currently available to them. The inclusion of this forward-looking information should not be regarded as a representation by Dril-Quip or Innovex that the future plans, estimates or expectations contemplated by them will be achieved. Such forward-looking statements are subject to various risks and uncertainties and assumptions about future events that may or may not be correct or necessarily take place and that are by their nature subject to significant uncertainties and other factors, many of which are beyond Dril-Quip’s and Innovex’s control. These factors and risks include, but are not limited to: the impact of actions taken by the Organization of Petroleum Exporting Countries (“OPEC”) and non-OPEC nations to adjust their production levels, risks related to the proposed transaction, including, the prompt and effective integration of Dril-Quip’s and Innovex’s businesses and the ability to achieve the anticipated synergies and value-creation contemplated by the proposed transaction; the risk associated with Dril-Quip’s ability to obtain the approval of the proposed transaction by its stockholders required to consummate the proposed transaction and the timing of the closing of the proposed transaction, including the risk that the conditions to the transaction are not satisfied on a timely basis or at all and the failure of the transaction to close for any other reason; the risk that a consent or authorization that may be a required approval for the proposed transaction is not obtained or is obtained subject to conditions that are not anticipated; unanticipated difficulties or expenditures relating to the transaction, the response of business partners and retention as a result of the announcement and pendency of the transaction; and the diversion of management time on transaction related issues, the impact of general economic conditions, including inflation, on economic activity and on Dril-Quip’s and Innovex’s operations, the general volatility of oil and natural gas prices and cyclicality of the oil and gas industry, declines in investor and lender sentiment with respect to, and new capital investments in, the oil and gas industry, project terminations, suspensions or scope adjustments to contracts, uncertainties regarding the effects of new governmental regulations, Dril-Quip’s and Innovex’s international operations, operating risks, the impact of our customers and the global energy sector shifting some of their asset allocation from fossil-fuel production to renewable energy resources, and other factors detailed in Dril-Quip’s public filings with the Securities and Exchange Commission (the “SEC”). Investors are cautioned that any such statements are not guarantees of future performance and actual outcomes may vary materially from those indicated. The occurrence of any such factors, events or circumstances would significantly alter the results set forth in these statements. The forward-looking statements made in this Presentation relate only to events as of the date of this Presentation. Neither Dril-Quip nor Innovex undertake any obligation to publicly or otherwise update or review any forward-looking statement except as required by law, whether as a result of new information, future developments or otherwise. If one or more of these or other risks or uncertainties materialize, or if Dril-Quip’s and Innovex’s underlying assumptions prove to be incorrect, actual results may vary materially from what we may have expressed or implied by these forward-looking statements. Dril-Quip and Innovex caution that you should not place undue reliance on any of our forward-looking statements. Furthermore, new risks and uncertainties arise from time to time, and it is impossible for Dril-Quip and Innovex to predict those events or how they may affect them. Past performance is not a reliable indicator of future results. Important Information for Stockholders In connection with the proposed merger of Dril-Quip and Innovex, Dril-Quip filed with the SEC a registration statement on Form S-4 (as amended, the “Registration Statement”) on May 1, 2024 that included a proxy statement/prospectus (the “Proxy Statement/Prospectus”). The Registration Statement was declared effective by the SEC on August 6, 2024. Dril-Quip filed the definitive proxy statement/prospectus with the SEC on August 6, 2024, and it was first mailed to Dril-Quip’s stockholders on August 6, 2024. Dril-Quip has filed other relevant documents with the SEC regarding the proposed merger. This document is not a substitute for the Proxy Statement/Prospectus or Registration Statement or any other document that Dril-Quip has filed with the SEC. STOCKHOLDERS ARE URGED TO CAREFULLY READ THE REGISTRATION STATEMENT, PROXY STATEMENT/PROSPECTUS (INCLUDING ALL AMENDMENTS AND SUPPLEMENTS THERETO) AND OTHER RELEVANT DOCUMENTS THAT HAVE BEEN FILED BY DRIL-QUIP WITH THE SEC IN THEIR ENTIRETY BECAUSE THEY CONTAIN IMPORTANT INFORMATION ABOUT THE PROPOSED MERGER. Such stockholders can obtain free copies of the Registration Statement and Proxy Statement/Prospectus and other documents containing important information about Dril-Quip, Innovex and the proposed merger through the website maintained by the SEC at http://www.sec.gov. Additional information is available on Dril-Quip’s website, www.dril-quip.com. Industry Information We obtained the industry, market and competitive position data used throughout this Presentation from our own internal estimates and research, as well as from independent industry publications, government publications and other published independent sources. Internal estimates are derived from publicly available information released by industry analysts and third-party sources, our internal research and our industry experience and are based on assumptions made by us based on such data and our knowledge of the industry and market, which we believe to be reasonable. In addition, while we believe the industry, market and competitive position data included in this Presentation is reliable and based on reasonable assumptions, we have not independently verified the accuracy or completeness of any third-party information. Some data is also based on our good faith estimates. The industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of factors. These and other factors could cause results to differ materially from those expressed in these publications. Forecasts and other forward-looking statements obtained from these sources are subject to the same qualifications and uncertainties as the other forward-looking statements in this Presentation. No representation or warranty, express or implied, is made as to the fairness, accuracy, completeness or correctness of the information contained herein and no reliance should be placed on it. None of Innovex, the underwriters or any of their respective affiliates, advisers, connected persons or any other person accept any liability for any loss howsoever arising (in negligence or otherwise), directly or indirectly, from this Presentation or its contents or otherwise arising in connection with this Presentation. This shall not, however, restrict or exclude or limit any duty or liability to a person under any applicable law or regulation of any jurisdiction that may not lawfully be disclaimed. The information contained in this Presentation is provided as at the date of this Presentation and is subject to change without notice. Financial Information: Non-GAAP Financial Measures This Presentation contains both financial measures prepared and presented in accordance with GAAP and non-GAAP financial measures, which are measurements of financial performance that are not prepared and presented in accordance with GAAP. Accordingly, these measures should not be considered as a substitute for data prepared and presented in accordance with GAAP. These non-GAAP financial measures, including Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow and Return on Capital Employed ( ROCE ), are or have been used by Innovex’s management when evaluating results of operations and as otherwise described below. Non-GAAP financial measures should not be construed as being more important than comparable GAAP measures. Innovex’s management believes these non-GAAP financial measures provide users of our financial statements with additional and useful comparisons of current results of operations with past and future periods. Although we use or have used these non-GAAP financial measures to assess the performance of our business and for the other purposes, the use of these non-GAAP financial measures as an analytical tool has limitations, and you should not consider them in isolation, or as a substitute for analysis of our results of operations as reported in accordance with GAAP. In addition, because not all companies use identical calculations, the non-GAAP financial measures included in this Presentation may not be comparable to similarly titled measures disclosed by other companies, including our peers or other companies in our industry. Please see “Appendix: Supplemental Materials” within the Presentation for reconciliations of the non-GAAP financial measures included in the Presentation to our most directly comparable financial measures calculated and presented in accordance with GAAP. Trademarks This Presentation contains trademarks, service marks, trade names and copyrights of Innovex, Dril-Quip and other companies, which are the property of their respective owners. 2
