All statements other than statements of historical facts contained in this Form 10-Q are forward-looking statements. Forward-looking statements are all statements other than statements of historical fact, and given our expectations or forecasts of future events as of the effective date of this Form 10-Q. Words such as "may," "could," "plan," "project," "budget," "predict," "target," "seek," "believe," "expect," "anticipate," "intend," "estimate," "will," "should" and similar expressions are generally used to identify forward-looking statements. These statements include, but are not limited to statements about our business strategy, industry, future profitability, future capital expenditures, our fleet conversion strategy and our share repurchase program. Such statements are subject to risks and uncertainties, many of which are difficult to predict and generally beyond our control, that could cause actual results to differ materially from those implied or projected by the forward-looking statements. Factors that could cause our actual results to differ materially from those contemplated by such forward-looking statements include:

•changes in general economic and geopolitical conditions, including as a result of 2024 presidential election, higher interest rates, the rate of inflation and a potential economic recession;

•central bank policy actions, bank failures and associated liquidity risks and other factors;

•the severity and duration of any world events and armed conflict, including the Russian-Ukraine war, conflicts in the Israel-Gaza region and continued hostilities in the Middle East, including rising tensions with Iran, and associated repercussions to supply and demand for oil and gas and the economy generally;

•the actions taken by the members of the Organization of the Petroleum Exporting Countries ("OPEC") and Russia (together with OPEC and other allied producing countries, "OPEC+") with respect to oil production levels and announcements of potential changes in such levels, including the ability of the OPEC+ countries to agree on and comply with supply limitations;

•actions taken by the current government, such as executive orders or new regulations, including climate-related regulations, that may negatively impact the future production of oil and natural gas in the United States and may adversely affect our future operations;

•the level of production and resulting market prices for crude oil, natural gas and other hydrocarbons;

•the effects of existing and future laws and governmental regulations (or the interpretation thereof) on us, our suppliers and our customers;

•cost increases and supply chain constraints related to our services, including any delays and/or supply chain disruptions due to increased hostilities in the Middle East;

•competitive conditions in our industry;

•our ability to attract and retain employees;

•changes in the long-term supply of, and demand for, oil and natural gas;

•actions taken by our customers, suppliers, competitors and third-party operators and the possible loss of customers or work to our competitors;

•technological changes, including lower emissions oilfield service equipment and similar advancements;

•changes in the availability and cost of capital;

•our ability to successfully implement our business plan, including execution of potential mergers and acquisitions;

•large or multiple customer defaults, including defaults resulting from actual or potential insolvencies;

-ii-

•regulatory and related policy actions intended by federal, state and/or local governments to reduce fossil fuel use and associated carbon emissions, or to drive the substitution of renewable forms of energy for oil and gas, may over time reduce demand for oil and gas and therefore the demand for our services;

•new or expanded regulations that materially limit our customers’ access to federal and state lands for oil and gas development, thereby reducing demand for our services in the affected areas;

•growing demand for electric vehicles that result in reduced demand for gasoline and therefore the demand for our services;

•our ability to successfully implement technological developments and enhancements, including our new Tier IV Dynamic Gas Blending ("DGB") dual-fuel and FORCESM electric-powered hydraulic fracturing equipment, and other lower-emissions equipment we may acquire or that may be sought by our customers;

•the projected timing, purchase price and number of shares purchased under our share repurchase program, the sources of funds under the repurchase program and the impacts of the repurchase program;

•operating hazards, natural disasters, weather-related delays, casualty losses and other matters beyond our control, such as fires, which risks may be self-insured, or may not be fully covered under our insurance programs;

•exposure to cyber-security events which could cause operational disruptions or reputational harm;

•acts of terrorism, war or political or civil unrest in the United States or elsewhere; and

•the effects of current and future litigation.

Whether actual results and developments will conform with our expectations and predictions contained in forward-looking statements is subject to a number of risks and uncertainties which could cause actual results to differ materially from such expectations and predictions, including, without limitation, in addition to those specified in the text surrounding such statements, the risks described under Part II, Item 1A, "Risk Factors" in this Form 10-Q and elsewhere throughout this report, the risks described under Part I, Item 1A, "Risk Factors" in our Form 10-K for the year ended December 31, 2023 (the "Form 10-K"), filed with the U.S. Securities and Exchange Commission (the "SEC") and elsewhere throughout that report, and other risks, many of which are beyond our control.

We do not undertake, and expressly disclaim, any duty to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by applicable securities laws.
