Cautionary Statement Regarding Forward-Looking Statements
Certain statements in this Current Report on Form 8-K and in the joint press release attached hereto as
Exhibit 99.1 may be considered forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In some cases, the reader can identify forward-looking
statements by words such as may, should, expect, intend, will, estimate, anticipate, believe, predict, or similar words. Forward-looking
statements relate to future events or ProFracs future financial or operating performance. These forward-looking statements include, among other things, statements regarding: the expected benefits of the Merger, including any resulting
synergies and positive impact on earnings, competitive advantages, expanded active fleet and electric fleet portfolio, increased value, improved efficiency, cost savings including fuel cost savings, access to and rights in acquired intellectual
property, emissions minimization and other expected advantages of the Merger; the anticipated timing of the Merger; the likelihood and ability of the parties to successfully consummate the Merger; the services offered by ProFrac and USWS; the
markets in which ProFrac and USWS operate; business strategies, debt levels, industry environment and growth opportunities; the projected value of operational synergies, including value expected to result from license fee savings; and expectations
regarding ProFracs ability to finance USWS debt. Such forward-looking statements are based upon assumptions made by ProFrac as of the date hereof and are subject to risks, uncertainties, and other factors that could cause actual results
to differ materially from those expressed or implied by such forward-looking statements. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: the risk that the Merger may not be
completed in a timely manner or at all, which may adversely affect the price of ProFrac securities; the failure to satisfy the conditions to the consummation of the Merger, including the approval of the Merger by the stockholders of each of ProFrac
and USWS, and the receipt of certain governmental and regulatory approvals; the failure to obtain financing to complete the Merger on favorable terms or at all; the effect of the announcement or pendency of the Merger on ProFracs and
USWS business relationships, performance, and business generally; risks that the Merger disrupts current plans of USWS and potential difficulties in USWS employee retention as a result of the Merger; the outcome of any legal
proceedings that may be instituted against ProFrac or USWS related to the Merger Agreement and the Merger; changes to the proposed structure of the business combination that may be required or appropriate as a result of applicable laws or
regulations or as a condition to obtaining regulatory approval of the Merger; the impact on the price of ProFracs securities, including volatility resulting from changes in the competitive and highly regulated industries in which ProFrac
operates, variations in performance across competitors, changes in laws and regulations affecting ProFracs business and changes in the combined capital structure; the ability to implement business plans, forecasts, and other expectations
after the completion of the Merger, and identify and realize additional opportunities; the ability to integrate acquired assets and personnel into our existing business model and realize the expected value of resulting operational synergies; the
ability to successfully and sustainably execute on current business strategies and plans for growth; and other risks and uncertainties set forth in the section entitled Risk Factors and Cautionary Note Regarding Forward-Looking
Statement in ProFracs final prospectus relating to its initial public offering (File No. 333-261255) declared effective by the SEC on May 12, 2022 (the ProFrac Final
Prospectus). The foregoing list of factors is not exhaustive. There may be additional risks that neither ProFrac nor USWS presently know or that ProFrac or USWS currently believe are immaterial that could also cause actual results to differ
from those contained in the forward-looking statements. You should carefully consider the foregoing factors and the other risks and uncertainties that will be described in the Proxy Materials (as defined below), including those under Risk
Factors therein, and other documents filed by ProFrac and USWS from time to time with the SEC, which are available on the SECs website at www.sec.gov. These filings identify and address other important risks and uncertainties that could
cause actual events and results to differ materially from those contained in the forward-looking statements.
Nothing in this Current
Report on Form 8-K or in the joint press release attached hereto as Exhibit 99.1 should be regarded as a representation by any person that the forward-looking statements set forth herein or therein will be
achieved or that any of the contemplated results of such forward looking statements will be achieved, including without limitation any expectations about ProFracs operational and financial performance or achievements. There may be additional
risks about which ProFrac is presently unaware or that ProFrac currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. Forward-looking statements speak only as of the
date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and ProFrac and USWS assume no obligation and, except as required by law, do not intend to update or revise these forward-looking statements, whether
as a result of new information, future events, or otherwise. Neither ProFrac nor USWS gives any assurance that either ProFrac or USWS will achieve its expectations, including that the Merger will be consummated.
