Item 1.01 Entry into a Material Definitive Agreement.

Merger Agreement

On June 14, 2023, NexTier Oilfield Solutions Inc., a Delaware corporation (“NexTier”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Patterson-UTI Energy, Inc., a Delaware corporation (“Patterson-UTI”), Pecos Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of Patterson-UTI (“Merger Sub Inc.”), and Pecos Second Merger Sub LLC, a Delaware limited liability company and wholly owned subsidiary of Patterson-UTI (“Merger Sub LLC”), pursuant to which, upon the terms and subject to the conditions set forth therein, (i) Merger Sub Inc. will merge with and into NexTier, with NexTier continuing as the surviving entity (the “Surviving Corporation”) (the “First Company Merger”) and (ii) immediately following the First Company Merger, the Surviving Corporation will merge with and into Merger Sub LLC, with Merger Sub LLC continuing as the surviving entity (the “Second Company Merger” and, together with the First Company Merger, the “Mergers”). Under the terms of the Merger Agreement and as more fully described below, at the effective time of the Mergers (the “Effective Time”), subject to certain exceptions, each share of common stock, par value $0.01 per share, of NexTier (“NexTier Common Stock”) then issued and outstanding immediately prior to the Effective Time (including each NexTier restricted stock award) will be converted into the right to receive 0.7520 shares of common stock, par value $0.01 per share, of Patterson-UTI (“Patterson-UTI Common Stock”). Each share NexTier Common Stock held in treasury by NexTier or owned directly or indirectly by Patterson-UTI, Merger Sub Inc. or Merger Sub LLC will be automatically cancelled and will cease to exist, and no consideration will be issued therefor. Upon consummation of the Mergers and the other transactions contemplated by the Merger Agreement (the “Transactions”), NexTier will be a wholly owned subsidiary of Patterson-UTI.

The board of directors of NexTier (the “NexTier Board”) unanimously (a) determined that the Merger Agreement and the Transactions are fair to, and in the best interests of, NexTier and the holders of shares of NexTier Common Stock, (b) approved and declared advisable the Merger Agreement and the Transactions on the terms and subject to the conditions set forth in the Merger Agreement, (c) directed that the Merger Agreement be submitted to the holders of shares of NexTier Common Stock for their adoption and (d) resolved to recommend that the holders of shares of NexTier Common Stock vote in favor of the adoption of the Merger Agreement. The board of directors of Patterson-UTI (the “Patterson-UTI Board”) unanimously (a) determined that the Merger Agreement and the Transactions are fair to, and in the best interests of, Patterson-UTI and the holders of shares of Patterson-UTI Common Stock, (b) approved and declared advisable the Merger Agreement, an amendment to the Restated Certificate of Incorporation of Patterson-UTI, dated as of October 14, 1993, as amended from time to time, to increase the authorized number of shares of Patterson-UTI Common Stock from 400,000,000 shares to 800,000,000 shares (the “Patterson-UTI Charter Amendment”) and the Transactions, on the terms and subject to the conditions set forth in the Merger Agreement, (c) directed that the issuance of Patterson-UTI Common Stock in connection with the Merger (the “Share Issuance”) and the Patterson-UTI Charter Amendment be submitted to the holders of shares of Patterson-UTI Common Stock for their approval and (d) resolved to recommend that the holders of shares of Patterson-UTI Common Stock vote in favor of the Share Issuance and the Patterson-UTI Charter Amendment.

Treatment of Long Term Incentive Awards

Pursuant to the Merger Agreement, at the Effective Time, (a) whether vested or unvested, each outstanding NexTier stock option will convert into a stock option relating to shares of Patterson-UTI Common Stock on the terms set forth in the Merger Agreement, (b) each outstanding NexTier performance stock unit award and NexTier performance unit award will convert into a Patterson-UTI performance stock unit award (or with a settlement value as provided in the NexTier performance stock unit award agreement) relating to shares of Patterson-UTI Common Stock on the terms set forth in the Merger Agreement and (c) each outstanding NexTier restricted stock unit award will convert into a Patterson-UTI restricted stock unit award relating to shares of Patterson-UTI Common Stock on the terms set forth in the Merger Agreement. The number of shares of NexTier Common Stock subject to NexTier performance stock unit awards or performance unit awards shall be deemed to be the number of shares subject to such NexTier performance stock unit award or performance unit award with performance deemed achieved based on actual performance attained through immediately prior to the date on which the closing of the Mergers actually occurs.

Post-Closing Governance

NexTier and Patterson-UTI have agreed to certain governance-related matters. At the Effective Time, the Patterson-UTI Board will have 11 members composed of (a) six directors designated by Patterson-UTI, which will include the Chief Executive Officer of Patterson-UTI as of immediately prior to the Effective Time and (b) five directors designated by NexTier, which will include the President and Chief Executive Officer of NexTier as of immediately prior to the Effective Time. The Chairman of the Patterson-UTI Board as of immediately prior to the Effective Time will serve as Chairman of the Board. The President and Chief Executive Officer of NextTier as of immediately prior to the Effective Time will serve as Vice Chairman of the Board. At the first two annual meetings following the Effective Time, the Patterson-UTI Board will re-nominate each Patterson-UTI and NexTier designee then serving on the Patterson-UTI Board for re-election by stockholders, subject to certain exceptions. In addition, at the Effective Time and for two years thereafter, (i) the Nominating and Corporate Governance Committee will have an equal number of Patterson-UTI and NexTier designees, (ii) all other committees will have at least one NexTier designee, such that the membership of all the committees (excluding the Executive Committee) of the Patterson-UTI Board, taken as a whole, will have an equal number of Patterson-UTI and NexTier designees and (iii) the Executive Committee will consist of the Chairman, Vice Chairman and Chief Executive Officer.

At the Effective Time, William A. Hendricks, Jr. will be appointed to serve as the chief executive officer of Patterson-UTI, C.

Representations, Warranties and Covenants

The Merger Agreement contains customary representations and warranties of NexTier and Patterson-UTI relating to their respective businesses, financial statements and public filings, as applicable, in each case generally subject to customary materiality and knowledge qualifiers. Additionally, the Merger Agreement provides for customary pre-closing covenants of NexTier and Patterson-UTI, including covenants relating to conducting their respective businesses in the ordinary course and to refrain from taking certain actions without the consent of the other party. NexTier and Patterson-UTI also agreed to use their reasonable best efforts to cause the Mergers to be consummated and to obtain regulatory approvals or expiration or termination of waiting periods.

The Merger Agreement provides that, during the period from the date of the Merger Agreement until the Effective Time, each of NexTier and Patterson-UTI will be subject to certain restrictions on its ability to solicit alternative Acquisition Proposals (as defined in the Merger Agreement) from third parties, to provide non-public information to third parties and to engage in discussions with third parties regarding alternative Acquisition Proposals, subject to customary exceptions. Patterson-UTI is required to call a meeting of its stockholders to approve the Share Issuance and Patterson-UTI Charter Amendment and, subject to certain exceptions, to recommend that its stockholders vote to approve the Share Issuance and Patterson-UTI Charter Amendment. NexTier is required to call a meeting of its stockholders to vote upon the adoption of the Merger Agreement and, subject to certain exceptions, to recommend that its stockholders vote to adopt the Merger Agreement.

Termination

The Merger Agreement contains termination rights for each of NexTier and Patterson-UTI, including, among others, if the consummation of the Transactions does not occur on or before March 14, 2024, subject to a 90-day extension in certain circumstances for the sole purpose of obtaining regulatory clearances. Upon termination of the Merger Agreement under specified circumstances, including the termination by NexTier in the event of a Change of Recommendation (as defined in the Merger Agreement) by the Patterson-UTI Board, Patterson-UTI would be required to pay NexTier a termination fee of $60.875 million. In addition, upon termination of the Merger Agreement under reciprocal specified circumstances, including the termination by Patterson-UTI in the event of a Change of Recommendation by the NexTier Board, NexTier would be required to pay Patterson-UTI a termination fee of $72.980 million. In addition, if the Merger Agreement is terminated in specified circumstances, including because of a failure of Patterson-UTI’s stockholders approve the Share Issuance and the Patterson-UTI Charter Amendment or of NexTier’s stockholders to approve the adoption of the Merger Agreement, Patterson-UTI or NexTier, as applicable, may be required to reimburse the other party for its actual transaction expenses in an amount not to exceed $10.15 million. In no event will either party be entitled to receive more than one termination fee, net of any expense reimbursement.

The foregoing description is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached as Exhibit 2.1 to this Current Report on Form 8-K.

The representations, warranties and covenants contained in the Merger Agreement have been made solely for the benefit of the parties thereto. In addition, such representations, warranties and covenants (i) have been made only for purposes of the Merger Agreement, (ii) have been qualified by (a) matters specifically disclosed in any reports filed by Patterson-UTI or NexTier with the SEC prior to the date of the Merger Agreement (subject to certain exceptions) and (b) confidential disclosures made in confidential disclosure letters delivered in connection with the Merger Agreement, (iii) are subject to materiality qualifications contained in the Merger Agreement which may differ from what may be viewed as material by investors, (iv) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement and (v) have been included in the Merger Agreement for the purpose of allocating risk between the contracting parties rather than establishing matters as fact. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the parties thereto or their respective businesses. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties to the Merger Agreement or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Patterson-UTI’s public disclosures. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding NexTier and Patterson-UTI that is or will be contained in, or incorporated by reference into, the Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and other documents that Patterson-UTI or NexTier files with the SEC.

Forward-Looking Statements

This Current Report on Form 8-K, including the exhibits hereto, contains “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 Current Report on Form 8-K that address activities, events or developments that NexTier or Patterson-UTI expects, believes or anticipates will or may occur in the future are forward-looking statements. Words such as “estimate,” “project,” “predict,” “believe,” “expect,” “anticipate,” “potential,” “create,” “intend,” “could,” “would,” “may,” “plan,” “will,” “guidance,” “look,” “goal,” “future,” “build,” “focus,” “continue,” “strive,” “allow” or the negative of such terms or other variations thereof and words and terms of similar substance used in connection with any discussion of future plans, actions, or events identify forward-looking statements. However, the absence of these words does not mean that the statements are not forward-looking. These forward-looking statements include, but are not limited to, statements regarding the expected closing of the proposed transaction and the timing thereof and as adjusted descriptions of the post-transaction company and its operations, strategies and plans, integration, debt levels and leverage ratio, capital expenditures, cash flows, synergies, opportunities and anticipated future performance, including the composition of the management team post-transaction, an expected accretion to earnings and free cash flow, increase in value of tax attributes, and expected impact on EBITDA. Information adjusted for the transaction should not be considered a forecast of future results. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in this Current Report on Form 8-K including, but not limited to, (i) the competitive nature of the industry in which NexTier and Patterson-UTI conduct their business, including pricing pressures; (ii) the ability to meet rapid demand shifts; (iii) the impact of pipeline capacity constraints and adverse weather conditions in oil or gas producing regions; (iv) the ability to obtain or renew customer contracts and changes in customer requirements in the markets NexTier and Patterson-UTI serve; (v) the ability to identify, effect and integrate acquisitions, joint ventures or other transactions; (vi) the ability to protect and enforce intellectual property rights; (vii) the effect of environmental and other governmental regulations on NexTier’s and Patterson-UTI’s operations; (viii) the effect of a loss of, or interruption in operations of, one or more key suppliers, including resulting from product defects, recalls or suspensions; (ix) the variability of crude oil and natural gas commodity prices; (x) the market price and availability of materials or equipment; (xi) the ability to obtain permits, approvals and authorizations from governmental and third parties; (xii) NexTier’s and Patterson-UTI’s ability to employ a sufficient number of skilled and qualified workers to combat the operating hazards inherent in NexTier’s and Patterson-UTI’s industry; (xiii) fluctuations in the market price of NexTier’s and Patterson-UTI’s stock; (xiv) the level of, and obligations associated with, NexTier’s and Patterson-UTI’s indebtedness; and (xv) other risk factors and additional information. In addition, material risks that could cause actual results to differ from forward-looking statements include: the inherent uncertainty associated with financial or other projections; the prompt and effective integration of NexTier’s businesses and the ability to achieve the anticipated synergies and value-creation contemplated by the proposed transaction; the risk associated with NexTier’s and Patterson-UTI’s ability to obtain the approval of the proposed transaction by their shareholders required to consummate the proposed transaction and the timing of the closing of the proposed transaction, including the risk that the conditions to the transaction are not satisfied on a timely basis or at all and the failure of the transaction to close for any other reason; the risk that a consent or authorization that may be required for the proposed transaction is not obtained or is obtained subject to conditions that are not anticipated; unanticipated difficulties or expenditures relating to the transaction, the response of business partners and retention as a result of the announcement and pendency of the transaction; and the diversion of management time on transaction-related issues. All such factors are difficult to predict and are beyond NexTier’s or Patterson-UTI’s control, including those

detailed in NexTier’s Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K that are available on NexTier’s website at www.nextierofs.com and on the website of the SEC at www.sec.gov, and those detailed in Patterson-UTI’s Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K that are available on the website of the SEC. All forward-looking statements are based on assumptions that NexTier and Patterson-UTI believe to be reasonable but that may not prove to be accurate. Any forward-looking statement speaks only as of the date on which such statement is made, and neither NexTier nor Patterson-UTI undertakes no obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof.
