Forward Looking Statements

This communication contains “forward-looking statements” within the Private Securities Litigation Reform Act of 1995. Any statements contained in this communication that are not statements of historical fact, including statements about FTSI’s ability to consummate the proposed transaction, the expected benefits of the proposed transaction and the expected impact of the coronavirus pandemic (COVID-19) on FTSI's businesses may be deemed to be forward-looking statements. All such forward-looking statements are intended to provide management’s current expectations for the future of FTSI based on current expectations and assumptions relating to FTSI’s business, the economy and other future conditions. Forward-looking statements generally can be identified through the use of words such

as “believes,” “anticipates,” “may,” “should,” “will,” “plans,” “projects,” “expects,” “expectations,” “estimates,” “forecasts,” “predicts,” “targets,” “prospects,” “strategy,” “signs,” and other words of similar meaning in connection with the discussion of future performance, plans, actions or events. Because forward-looking statements relate to the future, they are subject to inherent risks, uncertainties and changes in circumstances that are difficult to predict. Such risks and uncertainties include, among others: the failure to obtain the required vote of FTSI’s stockholders, the timing to consummate the proposed transaction, the risk that a condition of closing of the proposed transaction may not be satisfied or that the closing of the proposed transaction might otherwise not occur, the risk that a regulatory approval that may be required for the proposed transaction is not obtained or is obtained subject to conditions that are not anticipated, the diversion of management time on transaction-related issues, risks related to disruption of management time from ongoing business operations due to the proposed transaction, the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of the common stock of FTSI, the risk that the proposed transaction and its announcement could have an adverse effect on the ability of FTSI to retain customers and retain and hire key personnel and maintain relationships with its suppliers and customers, economic or political changes that affect the markets that FTSI’s businesses serve which could have an effect on demand for FTSI’s products and impact FTSI’s profitability, disruptions in the credit and financial markets, including diminished liquidity and credit availability, disruptions in the Company's businesses from the coronavirus pandemic (COVID-19), cyber-security vulnerabilities, supply issues, retention of key employees, and outcomes of legal proceedings, claims and investigations, future changes, results of operations, domestic spending by the onshore oil and natural gas industry, continued volatility or future volatility in oil and natural gas prices, deterioration in general economic conditions or a continued weakening or future weakening of the broader energy industry, federal, state and local regulation of hydraulic fracturing and other oilfield service activities, as well as exploration and production activities, including public pressure on governmental bodies and regulatory agencies to regulate our industry, and the price and availability of alternative fuels, equipment and energy sources. Accordingly, actual results may differ materially from those contemplated by these forward-looking statements. Investors, therefore, are cautioned against relying on any of these forward-looking statements. They are neither statements of historical fact nor guarantees or assurances of future performance. Additional information regarding the factors that may cause actual results to differ materially from these forward-looking statements is available in FTSI’s filings with the Securities and Exchange Commission, including the risks and uncertainties identified in Part I, Item 1A - Risk Factors of FTSI’s Annual Report on Form 10-K for the year ended December 31, 2020.

These forward-looking statements speak only as of the date of this communication, and FTSI does not assume any obligation to update or revise any forward-looking statement made in this communication or that may from time to time be made by or on behalf of the Company.

[The following memo was shared with vendors of FTS International, Inc. on October 22, 2021.]

I am pleased to share with you that FTS International has entered into an agreement to be acquired by ProFrac Holdings, a leading oilfield services company. Our combination creates one of the leading completions focused companies in the U.S. and brings together two strong industry players to deliver greater efficiencies and expanded equipment capabilities. As one company, we will have improved through-cycle resiliency via enhanced expertise, technology and scale – all of which should mean more opportunities for you to succeed in partnership with us in a rapidly evolving industry.

We expect the transaction to close in the first quarter of 2022 and, until that time, FTSI and ProFrac will continue to operate as two separate entities. Throughout this process, an integration planning team consisting of representatives from both companies will work together to determine how we can seamlessly bring together the best from both companies.

We do not anticipate any near-term changes in the way we work with you as a result of this transaction—it remains business as usual. We will provide additional updates throughout this process as we have them. Should you have any questions about this announcement, please do not hesitate to contact your FTSI representative. For more information, the press release announcing this transaction can be found on our website.

We value our relationship with you and look forward to the exciting opportunities ahead. Thank you for your ongoing support of FTSI.

This morning we announced that we have agreed to be acquired by ProFrac Holdings. A copy of the press release we issued about the transaction is available on our website at www.ftsi.com.

I want to highlight a few points that I think are important in understanding why we are pursuing this path and what it means for you.

I will host a town hall about the transaction this morning at 10:00 a.m. Central. You will be receiving an invite to this call with dial-in numbers.

It will also be recorded and available on the CREW for those who cannot attend. Additionally, Buddy and I will be visiting districts, sales offices, and many locations in the coming days and weeks to meet with as many of you as possible in person.

I’m incredibly grateful for all you do for the company. I know that you may feel anxious and will have questions about what this deal means for you. As we move toward completion of the transaction, which is expected to take place in the first quarter of 2022, I will make sure that you receive updates as we have them through town halls, e-mail, the CREW and your managers.
