Investor Presentation Cactus, Inc. (NYSE: WHD) May 2020

2 Non-GAAP Measures This presentation includes references to EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, and EBIT, which are not measures calculated in accordance with accounting principles generally accepted in the United States of America (“GAAP”). A reconciliation of EBITDA, Adjusted EBITDA and EBIT to net income, the most directly comparable measure calculated in accordance with GAAP, is provided in the Appendix included in this presentation. While management believes such measures are useful for investors, these measures should not be used as a replacement for financial measures that are calculated in accordance with GAAP. Forward-Looking Statements The information in this presentation includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical fact included in this presentation, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this presentation, the words “may,” “hope,” “potential,” “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on Cactus’ current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. We caution you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond our control, incident to the operation of our business. When considering forward-looking statements, you should keep in mind the risk factors and other cautionary statements described under the heading ‘‘Risk Factors’’ included in our SEC filings. These forward-looking statements are based on management’s current belief, based on currently available information, as to the outcome and timing of future events. Important factors that could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to: demand for our products and services, which is affected by, among other things, changes in the price of, and demand for, crude oil and natural gas in domestic and international markets; the level of growth in the number of rigs, pad sizes, well spacings and associated well count and availability of takeaway capacity; capital spending discipline practiced by customers; the level of fracturing activity; the size and timing of orders; availability of raw materials; transportation differentials associated with reduced capacity in and out of the storage hub in Cushing, Oklahoma; expectations regarding raw materials, overhead and operating costs and margins; availability of skilled and qualified workers; potential liabilities such as warranty and product liability claims arising out of the installation, use or misuse of our products; the possibility of cancellation of orders; our business strategy; our financial strategy, operating cash flows, liquidity and capital required for our business; our future revenue, income and operating performance; our ability to pay dividends; the termination of relationships with major customers or suppliers; laws and regulations, including environmental regulations, that may increase our costs, limit the demand for our products and services or restrict our operations; disruptions in the political, regulatory, economic and social conditions domestically or internationally; the ultimate severity and duration of the ongoing outbreak of coronavirus (COVID-19) and the extent of its impact on our business; outbreaks of other pandemic or contagious diseases that may disrupt our operations, suppliers or customers or impact demand for oil and gas; the impact of actions taken by the Organization of Petroleum Exporting Countries (OPEC) and other oil and gas producing countries affecting the supply of oil and natural gas; increases in import tariffs assessed on products from China and imported raw materials used in the manufacture of our goods in the United States which could negatively impact margins and our working capital; the significance of future liabilities under the tax receivable agreement we entered into with certain direct and indirect owners of Cactus LLC in connection with our IPO; a failure of our information technology infrastructure or any significant breach of security; potential uninsured claims and litigation against us; competition within the oilfield services industry; our dependence on the continuing services of certain of our key managers and employees; currency exchange rate fluctuations associated with our international operations; and plans, objectives, expectations and intentions contained in this presentation that are not historical. You are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date of this presentation. We disclaim any duty to update and do not intend to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this presentation.

The number of active U.S. onshore rigs Cactus followed represents the approximate number of active U.S. onshore drilling rigs to which Cactus was the primary provider of wellhead products and corresponding services during drilling, as of mid-month. Cactus believes that comparing the total number of active U.S. onshore rigs to which it is providing its products and services at a given time to the total number of active U.S. onshore rigs on or about such time provides Cactus with a reasonable approximation of its market share with respect to its wellhead products sold and the corresponding services it provides.

27 Important Disclosure Regarding Non-GAAP Measures EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP. EBITDA and Adjusted EBITDA are supplemental non-GAAP financial measures that are used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. We define EBITDA as net income excluding net interest, income tax and depreciation and amortization. We define Adjusted EBITDA as EBITDA excluding (gain) loss on debt extinguishment, stock-based compensation, and equity offering expenses. We define Adjusted EBITDA Margin as Adjusted EBITDA as a percentage of Revenue. Our management believes EBITDA and Adjusted EBITDA are useful, because they allow management to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to financing methods or capital structure, or other items that impact comparability of financial results from period to period. EBITDA and Adjusted EBITDA should not be considered as alternatives to, or more meaningful than, net income or any other measure as determined in accordance with GAAP. Our computations of EBITDA and Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. We present EBITDA and Adjusted EBITDA because we believe they provide useful information regarding the factors and trends affecting our business.
