ProPetro Reports Financial Results for the Second Quarter of 2026 MIDLAND, Texas, July 29, 2026, (Business Wire) – ProPetro Holding Corp. ("ProPetro" or "the Company") (NYSE: PUMP) today announced financial and operational results for the second quarter of 2026. Second Quarter 2026 Results and Highlights • Total revenue of $306 million, which increased 13% as compared to $271 million for the prior quarter. • Net loss was $8 million ($0.07 loss per diluted share) as compared to a net loss of $4 million in the prior quarter ($0.03 loss per diluted share). • Adjusted EBITDA(1) of $45 million was 15% of revenue and increased 23% as compared to the prior quarter. • Capital expenditures paid were $61 million and capital expenditures incurred were $71 million. • Net cash provided by operating activities and net cash used in investing activities were $66 million and $58 million, respectively. • Free Cash Flow from Completions Business(2) was $51 million. Recent PROPWR® Highlights • Added approximately 110 megawatts of power generation capacity committed under contract across two separate projects: one supporting a leading integrated upstream operator in the Permian Basin, and another supporting a separate industrial customer. This brings total capacity committed under contract to approximately 350 megawatts. • Engaged in advanced contract negotiations for over 100 megawatts to support other oil and gas operations. • Continued advancing negotiations across multiple data center commercial opportunities, including a subset of several hundred megawatts in advanced discussions. • Assets successfully deployed and operating at a Midwest hyperscaler data center site, making PROPWR one of the first behind-the-meter power providers actively servicing a data center project at scale providing prime power. (1) Adjusted EBITDA is a non-GAAP financial measure and is described and reconciled to net income (loss) in the table under “Non-GAAP Financial Measures.” (2) Free Cash Flow for Completions Business is a non-GAAP financial measure and is described and reconciled to net cash from operating activities in the table under “Non-GAAP Financial Measures." Management Comments Sam Sledge, Chief Executive Officer, commented, “ProPetro’s second quarter results once again demonstrate the strength of our business model. While our results were negatively impacted by a few items during the quarter, including upfront costs associated with standing up our twelfth fleet, a temporary out-of-basin fleet deployment that experienced significant unexpected downtime, and severe weather interrupting our operations across the Permian Basin in June, the underlying performance of the business remained strong. Even with these impacts, our completions business generated resilient free cash flow, a clear demonstration that the industrialized model we have built is working. As we look ahead, we remain encouraged by what we are seeing across our completions business. While uncertainty remains around the broader macro environment and the subsequent impacts from the Iran War, the market continues to tighten as industry attrition has meaningfully reduced available frac capacity. Combined with disciplined capital allocation across the sector, these dynamics are creating a more constructive supply and demand environment and contributing to early pricing momentum. We are also seeing this momentum reflected in increased drilling activity, with the Permian Basin rig count up nearly EXHIBIT 99.1

10% off its first-quarter low, as operators respond to improving conditions, a leading indicator that supports the recovery we are seeing in completions. Our confidence in a more favorable operating environment going forward is also reflected in our decision to activate a thirteenth fleet, which we expect to begin contributing toward the end of the third quarter. PROPWR also continues to build meaningful momentum. Since our last earnings update, we have significantly increased our power generation capacity committed under contract to approximately 350 megawatts, while continuing to advance opportunities across the data center, oil and gas, and industrial markets. Importantly, we are no longer simply building a commercial pipeline, we now have assets successfully operating in the field and meeting performance obligations, strengthening our commercial position and providing customers with tangible examples of our execution capabilities. We believe ProPetro is well positioned with two complementary growth platforms: an increasingly constructive completions business and a rapidly expanding PROPWR platform. Supported by a strong balance sheet, disciplined capital allocation and an exceptional team, we remain confident in our ability to create long-term value for our shareholders.” Caleb Weatherl, Chief Financial Officer, commented, “ProPetro's financial strength remains a key c

ProPetro Reports Financial Results for the First Quarter of 2026 MIDLAND, Texas, April 30, 2026, (Business Wire) – ProPetro Holding Corp. ("ProPetro" or "the Company") (NYSE: PUMP) today announced financial and operational results for the first quarter of 2026. First Quarter 2026 Results and Highlights • Total revenue of $271 million, which decreased 7% as compared to $290 million for the prior quarter. • Net loss was $4 million ($0.03 loss per diluted share) as compared to a net income of $1 million in the prior quarter ($0.01 income per diluted share). • Adjusted EBITDA(1) of $36 million was 13% of revenue and decreased 29% as compared to the prior quarter. • Capital expenditures paid were $43 million and capital expenditures incurred were $85 million. • Net cash provided by operating activities and net cash used in investing activities were $3 million and $41 million, respectively. Recent PROPWR℠ Highlights • Entered into a strategic framework agreement with Caterpillar Inc., securing access to up to approximately 2.1 additional gigawatts of power generation capacity over the next five years which enhances long-term supply visibility and supports PROPWR’s continued growth. The Company is now positioned to have approximately 2.6 gigawatts of power generation capacity delivered by year-end 2031. • Engaged in advanced contract negotiations for approximately 100 megawatts to support oil and gas microgrid projects, with deployments expected later this year. • Achieved major advancements representing several hundred megawatts of high-potential data center opportunities, in a select portion of PROPWR's data center commercial pipeline. (1) Adjusted EBITDA is a non-GAAP financial measure and is described and reconciled to net income (loss) in the table under “Non-GAAP Financial Measures.” Management Comments Sam Sledge, Chief Executive Officer, commented, “ProPetro’s first quarter results once again demonstrated the resiliency of our business model. Despite weather-related disruptions that impacted activity and profitability, we delivered positive financial results in our completions business, particularly when measured by Adjusted EBITDA less incurred capital expenditures. These results highlight the strength of our industrialized model, which is the result of strategic investments, disciplined asset deployment, and rigorous cost management. The actions we took throughout 2025 to protect our assets and right-size our cost structure are benefiting us today and position us to perform successfully in this market. With respect to the broader environment, we are still in the early stages of assessing the global and domestic implications of the Iran War. While uncertainty remains, we are starting to see signs of recovery across the broader North American oilfield services sector, given a strengthening commodity backdrop that is driving early pricing and activity tailwinds across our completions business. Importantly, structural tightening in the completions market continues to intensify, driven by ongoing attrition, particularly among smaller less disciplined competitors. This trend was already emerging prior to the onset of the Iran War and has since accelerated with the recent increase in demand for U.S. frac activity. Notably, there was already very little spare frac equipment capacity even before the conflict began, further amplifying current market constraints. These dynamics, combined with ongoing capital investment discipline and pricing discipline, have tempered any plans to expand capacity both within ProPetro and among our close peers in the completions space. Collectively, these factors have created a more constructive supply and demand environment for our business over time. EXHIBIT 99.1

At the same time, our PROPWR business continues to gain significant momentum, advancing our growth strategy through the recently announced Framework Agreement with Caterpillar and the ongoing expansion of our contracted portfolio. Substantial growth opportunities remain ahead, especially within the rapidly evolving data center sector. We are pleased to report major advancements representing several hundred megawatts of high-potential data center opportunities, in a select portion of our commercial pipeline, further strengthening our presence in the digital infrastructure space. We now have two powerful engines driving our business forward: an improving completions market, and a rapidly expanding PROPWR platform. As always, we will remain focused on what we can control, cost discipline, operational excellence, and strategic capital deployment. With these strengths, we are confident that ProPetro is well positioned to capitalize on the current tailwinds in the completions business and deliver sustained, long-term earnings growth through PROPWR.” Caleb Weatherl, Chief Financial Officer, commented, “During the first quarte

Item 2.02 Results of Operations and Financial Conditions

On January 26, 2026, in connection with the Offering (as defined below), ProPetro Holding Corp. (the “Company”) provided certain updates in a preliminary prospectus supplement (the “Prospectus Supplement”), including certain preliminary fourth quarter and year-end financial and operational information.

As of the date of this Current Report on Form 8-K and the Prospectus Supplement, the Company has not finalized its financial and operational results for the three months ended December 31, 2025 or the year ended December 31, 2025. However, based on preliminary information, the Company estimates that, for the three months ended December 31, 2025 and the year ended December 31, 2025, each of the Company’s capital expenditures incurred, capital expenditures paid, revenues, cost of services and general and administrative expenses (exclusive of stock-based compensation and other non-recurring items) ranged approximately as follows:

Three Months Ended

December 31, 2025 Year Ended

December 31, 2025

(unaudited)

Capital expenditures incurred $ 70 – 72 million $ 280 – 282 million

Capital expenditures paid $ 63 – 65 million $ 185 – 187 million

Revenue $ 289 - 291 million $ 1,269 – 1,271 million

Cost of services $ 214 – 216 million $ 967 – 969 million

General and administrative expenses (1) $ 23 – 25 million $ 92 – 94 million

(1) Exclusive of stock-based compensation and other non-recurring items of approximately $5 million for the three months ended December 31, 2025, and approximately $15 million for the year ended December 31, 2025.

As of December 31, 2025, the Company had approximately $91 million in cash and cash equivalents, approximately $78 million of borrowings outstanding under the Company’s Caterpillar Equipment Loan Agreement and approximately $45 million of borrowings outstanding under the Company’s amended and restated revolving credit facility, with a borrowing base of approximately $168 million. Between January 1, 2026 and January 26, 2026, the Company incurred approximately $10 million in additional borrowings under the Company’s Caterpillar Equipment Loan Agreement. Additionally, under current market conditions, the Company expects to have approximately 11 active frac fleets in the first quarter of 2026, subject to any suspensions of the Company’s operations due to winter weather conditions.

The Company has provided ranges, rather than specific amounts, because these results are preliminary and subject to change. These preliminary estimates are derived from the Company’s internal records and are based on the most current information available to management as of the date of this Current Report on Form 8-K and the Prospectus Supplement. These estimates are preliminary and inherently uncertain. The Company’s normal reporting processes with respect to the foregoing preliminary estimates have not been fully completed. The

Item 1.01 Entry into a Material Definitive Agreement.

Purchase and Sale Agreement

On November 1, 2022, ProPetro Holding Corp. (the "ProPetro" or "Company") completed the acquisition (the "Silvertip Acquisition") of all of the outstanding limited liability company interests of Silvertip Completion Services Operating, LLC, a wireline services company, pursuant to that certain purchase and sale agreement (the “Purchase Agreement”) dated November 1, 2022, between the Company and New Silvertip Holdco, LLC (the “Seller”). The total consideration for the Silvertip Acquisition consisted of the issuance of 10.1 million shares of ProPetro common stock, $30 million of cash, the payoff of approximately $7 million of assumed debt, and certain other transaction costs, subject to customary post-closing adjustments, which implies a value of $150 million based upon a 15-day volume weighted average price ("VWAP") of ProPetro’s stock price as of October 27, 2022.

The foregoing description of the Purchase Agreement is not complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated into this Item 1.01 by reference.

Registration Rights and Lock-Up Agreement

In connection with the Silvertip Acquisition, the Company entered into a Registration Rights and Lock-Up Agreement, dated as of November 1, 2022 (the “Registration Rights Agreement”), with the Seller, pursuant to which the Company must file a shelf registration statement as soon as practicable, but in any event within three business days after the closing of the Silvertip Acquisition. The Seller and certain of its affiliates will also have the right to demand that the Company undertake an underwritten offering of shares comprising the Stock Consideration so long as the minimum market price of the shares to be included in the offering is $30 million, subject to certain other limitations. In addition, the Seller and certain of its affiliates will have certain “piggyback” rights if the Company or certain other holders of the Company’s common stock undertakes an underwritten offering, subject to customary cutbacks.

Pursuant to the terms of the Registration Rights Agreement, Seller agreed, subject to certain customary exceptions, not to, directly or indirectly, sell, offer or agree to sell, or otherwise transfer, or loan or pledge, through swap or hedging transactions, or grant any option to purchase, make any short sale or otherwise dispose of 90% of the shares comprising the Stock Consideration for specified periods of time ranging from six to eighteen months following the closing of the Silvertip Acquisition, as described in the Registration Rights Agreement.
