PRELIMINARY—SUBJECT TO COMPLETION—DATED DECEMBER 4, 2024

JOINT PROXY STATEMENT/ PROSPECTUS

MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

The board of directors of Nabors Industries Ltd. (“Nabors”) and the board of directors of Parker Drilling Company (“Parker”) have each approved an Agreement and Plan of Merger, which is attached as Annex A to this joint proxy statement/prospectus (as it may be amended from time to time, the “merger agreement”), that provides for the combination of Nabors and Parker through the merger. Pursuant to the terms of the merger agreement, Nabors SubA Corporation, a Delaware corporation and a wholly owned subsidiary of Nabors (“Merger Sub”), will merge with and into Parker (the “merger”), with Parker surviving the merger as a wholly owned subsidiary of Nabors and the separate existence of Merger Sub ceasing.

If the merger is completed, each share of Parker common stock, par value $0.01 per share (“Parker common stock”), issued and outstanding immediately prior to acceptance of the filing of the Certificate of Merger with the Office of the Secretary of State of the State of Delaware (the “effective time”) (other than dissenting shares) will be converted into the right to receive (i) a number of Nabors common shares, par value $0.05 per share (“Nabors common shares”), and, (ii) in certain circumstances, a payment in cash (A) as set forth below if the Closing Price is less than the Lower Collar Price (each as defined below), (B) in lieu of any fractional shares and/or (C) in connection with the sale by Parker of Rig 77B (the “Barge Rig Holdback Amount”) (collectively, the “merger consideration”). Subject to certain adjustments as described in the merger agreement, the share portion of merger consideration will be calculated as follows:

Each Parker stockholder’s pro rata share of the merger consideration is referred to as the “per share merger consideration.”

The Parker common stock will thereafter cease to be outstanding and will automatically be cancelled, extinguished and retired and will cease to exist, and the holders of the shares of Parker common stock immediately prior to the effective time will cease to have any rights with respect to the shares of Parker common stock, except for (i) the right to receive (without interest) the per share merger consideration or (ii) with regard to shares held by Parker stockholders who did not vote in favor of the Parker merger proposal (as defined below) or otherwise consent thereto in writing and who properly exercised appraisal rights in respect of their shares of Parker common stock in accordance with the General Corporation Law of the State of Delaware (the “DGCL”), the rights of holders of “dissenting shares” under the DGCL.

Each share of Parker common stock held in the treasury of Parker or held by Nabors or Merger Sub immediately prior to the effective time will automatically be cancelled and retired without any conversion thereof, and no payment or distribution will be made with respect thereto.

Nabors will issue up to 4,800,000 Nabors common shares as merger consideration, or, if the Closing Price is greater than the Upper Collar Price, the number of Nabors common shares equal to the Upper Collar Value divided by the Closing Price. There are other downward adjustments in the number of Nabors common shares to be issued as described in the merger agreement. Based on the closing price of Nabors common shares on the NYSE, on October 14, 2024, the last trading day before public announcement of the merger, the aggregate value of the merger consideration payable to Parker stockholders was approximately $372.1 million, assuming the issuance of 4,800,000 Nabors common shares.

After the closing of the merger, Parker will retain the Barge Rig Holdback Amount until the final excess transaction expenses amount is finally determined pursuant to the terms of the merger agreement (the “Barge Rig Holdback Period”). After the expiration of the Barge Rig Holdback Period, Parker will, subject to certain conditions of the merger agreement, cause the then remaining amount of the Barge Rig Holdback Amount to be disbursed to the Parker stockholders in accordance with their applicable per share merger consideration. Any amounts received by Parker with respect to the sale of Rig 77B after the closing of the merger will not become part of the Barge Rig Holdback Amount.

Each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the effective time will be converted into and become one newly issued, fully paid, and non-assessable share of common stock, par value $0.01 per share, of Parker, as the surviving entity in the merger, with the same rights, powers, and privileges as the shares so converted. These shares will constitute the only outstanding shares of capital stock of Parker after the effective time.

Nabors common shares outstanding before the merger is completed will remain outstanding and will not be exchanged, converted or otherwise changed in the merger. Nabors common shares are currently traded on the NYSE, under the symbol “NBR.” We urge you to obtain current market quotations of Nabors common shares and Parker common stock.

We intend for the merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”).

Accordingly, Parker stockholders generally are not expected to recognize any gain or loss for U.S. federal income tax purposes upon the exchange of shares of Parker common stock for Nabors common shares pursuant to the merger, except with respect to cash received if the Closing Price is lower than the Lower Collar Price, cash received in connection with the disbursement of certain amounts received in connection with the Barge Rig Holdback Amount and cash received in lieu of fractional Nabors common shares. If, however, cash received by Parker stockholders in respect of their Parker common stock (e.g., from cash received if the Closing Price is lower than the Lower Collar Price, cash received in connection with the disbursement of certain amounts received in connection with the Barge Rig Holdback Amount and cash received in lieu of fractional Nabors common shares) exceeds 20% of the total consideration received in respect of Parker common stock, then the merger is not expected to qualify as a “reorganization” within the meaning of Section 368(a) of the Code and the merger would be fully taxable to Parker stockholders.

Based on the estimated number of Nabors common shares and shares of Parker common stock that will be outstanding immediately prior to the closing of the merger, we estimate that, as of the closing, former Parker stockholders will own approximately 31% of the combined company.

At a special meeting of Parker stockholders, Parker stockholders will be asked to vote on (i) a proposal to approve and adopt the merger agreement (the “Parker merger proposal”) and (ii) a proposal to approve the adjournment of the Parker special meeting, if necessary or appropriate, to permit further solicitation of proxies (the “Parker adjournment proposal”). Approval of the Parker merger proposal requires the affirmative vote of a majority of the outstanding shares of Parker common stock entitled to vote on the proposal. Approval of the Parker adjournment proposal requires the affirmative vote of a majority of the votes cast on the proposal.

Simultaneously with the execution of the merger agreement, certain stockholders of Parker (collectively, the “supporting stockholders”) entered into a voting and support agreement with Nabors (the “voting and support agreement”), pursuant to which the supporting stockholders have agreed to, among other things, (i) vote their shares of Parker common stock in favor of the merger agreement and the merger and (ii) waive any rights of appraisal or rights to dissent in connection with the merger. The supporting stockholders owned approximately 85.04% of the outstanding shares of Parker common stock as of the date of the voting and support agreement.

Also, simultaneously with the execution of the merger agreement, the supporting stockholders have entered into separate voting and lock-up agreements (the “voting and lock-up agreements”) with Nabors to become effective at the closing of the merger and pursuant to which, the supporting stockholders, subject to certain exceptions, agree to, among other things, (i) vote in favor of any proposal recommended by the Nabors board of directors and in favor of any candidate for the Nabors board of directors nominated by the Nabors board of directors, (ii) not sell, pledge or otherwise dispose of the shares acquired in the merger until the 90th day following the closing of the merger (the “lock-up period”) (iii) subject to certain exceptions, not transfer (a) any shares acquired in the merger to any person if such person, immediately following the consummation of such transfer, will beneficially own more than 5% of the outstanding Nabors common shares or (b) any shares acquired in the merger to any competitor of Nabors and (iv) comply with certain standstill provisions with regards to Nabors. The supporting stockholders may transfer up to 40% of the Nabors common shares they receive in the merger during the lock-up period.

At a special general meeting of Nabors shareholders, Nabors shareholders will be asked to vote on the proposal to approve the issuance of Nabors common shares to Parker stockholders in connection with the merger (the “Nabors share issuance proposal”). Approval of the Nabors share issuance proposal requires the affirmative vote of a majority of the Nabors common shares, present virtually or represented by proxy at the Nabors special general meeting and entitled to vote on the proposal, assuming a quorum is present. At the Nabors special general meeting, Nabors shareholders will also be asked to vote on a proposal to approve the adjournment of the Nabors special general meeting, if necessary or appropriate, to permit further solicitation of proxies (the “Nabors adjournment proposal”). The approval of the Nabors adjournment proposal requires the affirmative vote of a majority of the Nabors common shares, present virtually or represented by proxy at the Nabors special general meeting and entitled to vote thereon, regardless of whether there is a quorum.

The board of directors of Parker unanimously recommends that the Parker stockholders vote “FOR” the Parker merger proposal and “FOR” the Parker adjournment proposal.

The board of directors of Nabors unanimously recommends that the Nabors shareholders vote “FOR” the Nabors share issuance proposal and “FOR” the Nabors adjournment proposal.

The obligations of Nabors and Parker to complete the merger are subject to the satisfaction or waiver of several conditions set forth in the merger agreement. The accompanying joint proxy statement/prospectus contains detailed information about Nabors, Parker, the special meetings, the merger agreement and the merger. Nabors and Parker encourage you to read the joint proxy statement/prospectus carefully and in its entirety before voting, including the section titled “Risk Factors”.

We look forward to the successful combination of Nabors and Parker.

Sincerely,

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the securities to be issued under the joint proxy statement/prospectus or determined if the joint proxy statement/prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The joint proxy statement/prospectus is dated [    ] and is first being mailed to Nabors shareholders and Parker stockholders on or about [    ].

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This joint proxy statement/prospectus and the documents incorporated by reference into this joint proxy statement/prospectus contain forward-looking statements within the meaning of the federal securities laws that are not limited to historical facts, but reflect Nabors’ and/or Parker’s current beliefs, expectations or intentions regarding future events. Statements in this joint proxy statement/prospectus and the documents incorporated by reference herein that are not historical facts are hereby identified as “forward-looking statements” for the purpose of the safe harbor provided by Section 21E of the Exchange Act, and Section 27A of the Securities Act. Words such as “may,” “will,” “could,” “should,” “expect,” “plan,” “project,” “intend,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “pursue,” “target,” “continue,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, Nabors’ and Parker’s expectations with respect to the synergies, costs and other anticipated financial impacts of the proposed transaction; future financial and operating results of the combined company; the combined company’s plans, objectives, expectations and intentions with respect to future operations and services; approval of the proposed transaction by shareholders and stockholders; the satisfaction of the closing conditions to the proposed transaction; and the timing of the completion of the proposed transaction.

Although Nabors and Parker believe the expectations reflected in such forward-looking statements are reasonable, such expectations may not occur. These forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of the combined company to be materially different from actual future results expressed or implied by the forward-looking statements. These risks and uncertainties also include those set forth under “Risk Factors,” as well as, among others, risks and uncertainties relating to:

27

28

Nabors and Parker caution that the foregoing list of factors is not exclusive. Additional information concerning these and other risk factors is contained in Nabors’ most recently filed Annual Reports on Form 10-K, subsequent Quarterly Reports on Form 10-Q, recent Current Reports on Form 8-K and other SEC filings. The forward-looking statements speak only as of the date made and, other than as required by law, neither Nabors nor Parker undertake any obligation to update publicly or revise any of these forward-looking statements, whether as a result of new information, future events or otherwise. In the event that a party does update any forward-looking statement, no inference should be made that the parties will make additional updates with respect to that statement, related matters or any other forward-looking statements. All subsequent written and oral forward-looking statements concerning Nabors, Parker, the merger or other matters and attributable to Nabors or Parker or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above.

29

RISK FACTORS

In addition to the other information included and incorporated by reference into this joint proxy statement/prospectus, including the matters addressed in the section titled “Special Note Regarding Forward-Looking Statements,” you should carefully consider the following risks before deciding whether to vote for any of the proposals described in this joint proxy statement/prospectus. In addition, you should read and consider the risks associated with each of the businesses of Nabors and Parker because these risks will also affect the combined company following the merger. The risks related to Nabors’ business can be found in its Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as those risks may be updated or supplemented in its subsequently filed Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, to the extent incorporated by reference into this joint proxy statement/prospectus. You should also read and consider the other information in this joint proxy statement/prospectus and the other documents incorporated by reference into this joint proxy statement/prospectus. See the section titled “Where You Can Find More Information”.

Risk Factors Relating to the Merger

The market value of Nabors common shares could be negatively affected by risks and conditions that apply to Nabors, which may be different from the risks and conditions applicable to Parker, and Nabors shareholders will have different rights than Parker stockholders.

Following the merger, shareholders of Nabors and former stockholders of Parker will own interests in a combined company operating an expanded business with more assets and a different mix of liabilities. The business of Nabors and its subsidiaries and other companies it may acquire in the future are different from those of Parker. There is a risk that various factors, conditions and developments that would not affect the price of Parker common stock could negatively affect the price of Nabors common shares. Current shareholders of Nabors and current stockholders of Parker may not wish to continue to invest in the combined company, or may wish to reduce their investment in the combined company, including in order to comply with institutional investing guidelines, to increase diversification, to track any rebalancing of stock indices in which Nabors common shares are included, to respond to the risk profile of the combined company or to realize a gain. In addition, if, following the merger, large amounts of Nabors common shares are sold, the price of Nabors common shares could decline.

Holders of Nabors common shares will have rights as Nabors shareholders that differ from the rights they had as Parker stockholders before the merger. For a detailed comparison of the rights of Nabors shareholders to the rights of Parker stockholders, see “Comparison of Rights of Nabors Shareholders and Parker Stockholders”.

Current Nabors shareholders will have a reduced ownership and voting interest in the combined company after the merger.

Nabors will issue up to 4,800,000 Nabors common shares to Parker stockholders in the merger. As a result of these issuances, Parker stockholders are expected to hold up to approximately 31% of the combined company’s outstanding common shares immediately following completion of the merger.

Nabors shareholders currently have the right to vote for Nabors’ directors and on other matters affecting the company. Each Nabors shareholder will remain a shareholder of Nabors with a percentage ownership of the combined company that will be smaller than the shareholder’s percentage of Nabors prior to the merger. As a result of these reduced ownership percentages, Nabors shareholders will have less voting power in the combined company than they now have with respect to Nabors.

30

The merger is subject to conditions, including certain conditions that may not be satisfied, or completed on a timely basis, if at all.

The merger is subject to a number of conditions beyond Nabors’ and Parker’s control that may prevent, delay or otherwise materially adversely affect its completion. We cannot predict whether and when these conditions will be satisfied. Any delay in completing the merger could cause the combined company not to realize some or all of the benefits that we expect to achieve if the merger is successfully completed within its expected time frame. See section titled “The Merger Agreement—Conditions to Completion of the Merger”.

Failure to complete the merger could negatively impact the future business and financial results of Nabors and Parker.

The merger is subject to a number of conditions beyond Nabors’ and Parker’s control that may prevent, delay or otherwise materially adversely affect its completion. Such conditions include, but are not limited to, regulatory approval from the FTC and Department of Justice as required under the HSR Act and certain clearances, consents and approvals under certain specified antitrust regulatory laws in several foreign jurisdictions in which the companies have a sufficient market presence to require filings. We cannot make any assurances that we will be able to satisfy all of the conditions to the merger or succeed in any litigation brought in connection with the merger. If the merger is not completed, our financial results may be adversely affected and we will be subject to several risks, including but not limited to:

In addition, if the merger is not completed, Nabors and/or Parker may experience negative reactions from the financial markets and from their respective customers and employees. If the merger is not completed, Parker and Nabors cannot assure their respective stockholders that these risks will not materialize and will not materially and adversely affect the business, financial results and stock price of Parker or Nabors.

The merger agreement contains provisions that restrict Parker’s ability to pursue alternatives to the merger, could discourage a potential competing acquiror of Parker from making a favorable alternative transaction proposal and, in specified circumstances, could require Parker to pay a termination fee to Nabors.

The merger agreement contains “non-solicitation” provisions that restrict Parker’s ability to, among other things, directly or indirectly discuss, encourage, negotiate, undertake, initiate, authorize, recommend, propose or enter into any business combination transaction for any amount of the assets or equity interests of Parker. In addition, Parker may not terminate the merger agreement to accept an alternative proposal. Moreover, in certain circumstances, Parker may be required to pay Nabors a termination fee of $10,000,000 under certain circumstances provided in the merger agreement.

These provisions could discourage a potential third party that might have an interest in acquiring all or a significant portion of Parker from considering or proposing that acquisition, even if it were prepared to pay consideration with a higher per share cash or market value than the market value proposed to be received or

31

realized in the merger. In addition, these provisions might result in a potential third-party acquirer proposing to pay a lower price to the stockholders than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable in certain circumstances.

See “The Merger Agreement—No Solicitation of Competing Proposals”, “The Merger Agreement—Termination of the Merger Agreement” and “The Merger Agreement—Termination Fees and Expenses”.

Parker’s directors and executive officers have interests in the merger that may be different from, or in addition to, the interests of Parker stockholders generally.

In considering the recommendation of the Parker board of directors that Parker stockholders vote in favor of the Parker merger proposal, Parker stockholders should be aware of and take into account the fact that Parker directors and executive officers have interests in the merger that may be different from, or in addition to, the interests of Parker stockholders generally. These interests include, among others, severance payments, rights to continuing indemnification and directors’ and officers’ liability insurance and accelerated vesting of outstanding equity awards held by non-employee directors. See “The Merger—Interests of Parker Directors and Executive Officers in the Merger” for a more detailed description of these interests. The Parker board of directors was aware of and carefully considered these interests, among other matters, in evaluating the terms and structure, and overseeing the negotiation, of the merger, in approving the merger agreement and the transactions contemplated thereby, including the merger, and in recommending that the Parker stockholders approve the Parker merger proposal.

Completion of the merger will trigger change in control or other provisions in certain agreements to which Parker is a party.

The completion of the merger will trigger change in control or other provisions in certain agreements to which Parker is a party. If Nabors and Parker are unable to negotiate waivers of those provisions, the counterparties may exercise their rights and remedies under the agreements, potentially terminating the agreements or seeking monetary damages. Even if Nabors and Parker are able to negotiate waivers, the counterparties may require a fee for such waivers or seek to renegotiate the agreements on terms less favorable to Parker or the combined company.

Nabors and Parker may be unable to obtain the regulatory clearances and approvals required to complete the merger or, in order to do so, Nabors and Parker may be required to comply with material restrictions or conditions.

Under the HSR Act, neither Nabors nor Parker may complete the merger until required information and materials are furnished to the Antitrust Division and the FTC, and the applicable waiting period under the HSR Act terminates or expires. On October 21, 2024, Nabors and Parker each filed Notification and Report Forms with the Antitrust Division and the FTC. On November 20, 2024, the waiting period under the HSR Act expired without a request for additional information or documentary material from the Antitrust Division or the FTC.

Consummation of the merger is also subject to the receipt of clearances, consents and approvals under certain specified antitrust regulatory laws in several foreign jurisdictions in which the companies have a sufficient market presence to require filings, namely: Colombia, Kazakhstan, Kuwait, and Saudi Arabia. As of the date hereof, the parties have either submitted filings or are in the process of finalizing filings in these jurisdictions. The merger may also be subject to the regulatory requirements of other municipal, state, federal, or foreign governmental agencies and authorities. Regulatory entities may impose certain requirements or obligations as conditions for their approval or in connection with their review.

At any time before or after consummation of the merger, notwithstanding the expiration of the applicable waiting period under the HSR Act, the FTC, the Antitrust Division or any state could take such action

32

under the antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the merger or seeking the divestiture of substantial assets of Nabors or Parker or their respective subsidiaries or requiring Nabors or Parker to license, or hold separate, assets or terminate existing relationships and contractual rights. At any time before or after the completion of the merger, and notwithstanding the expiration of the applicable waiting period under the HSR Act, any state could take such action under the antitrust laws as it deems necessary or desirable in the public interest. Such action could include seeking to enjoin the completion of the merger or seeking divestiture of substantial assets of Nabors or Parker. Private parties may also seek to take legal action under the antitrust laws under certain circumstances.

Neither Nabors nor Parker can provide any assurance that they will obtain the necessary clearances, approvals or expirations or terminations of applicable waiting periods in a timely manner or at all, or that any conditions to such clearances, approvals, expirations or terminations will not have a material adverse effect on the combined company following the merger or result in the abandonment of the merger.

Additionally, even after the above-described clearances and approvals have been obtained, and statutory waiting periods have expired or terminated, and even after completion of the merger, governmental authorities could seek to challenge the merger. Nabors or Parker may not prevail and may incur significant costs in defending or settling any action under the antitrust laws.

The pendency of the merger could adversely affect the business and operations of Nabors and Parker.

In connection with the pending merger, some customers or vendors of each of Nabors and Parker may delay or defer decisions, which could negatively affect the revenues, earnings, cash flows and expenses of Nabors and Parker regardless of whether the merger is completed. Similarly, current and prospective employees of Nabors and Parker may experience uncertainty about their future roles with Parker following the merger, which may materially adversely affect the ability of each of Nabors and Parker to attract, retain and motivate key personnel during the pendency of the merger and which may materially adversely divert attention from the daily activities of Nabors’ and Parker’s existing employees.

Due to operating covenants in the merger agreement, each of Nabors and Parker may be unable, during the pendency of the merger, to pursue strategic transactions, undertake significant capital projects, undertake certain significant financing transactions and otherwise pursue other actions that are not in the ordinary course of business, even if such actions would prove beneficial to Nabors or Parker, as applicable. Further, the process of seeking to consummate the merger could also divert the focus of management of either company from pursuing other opportunities that could be beneficial to it, without realizing any of the benefits which might have resulted had the merger been completed.

If the merger does not qualify as a reorganization within the meaning of Section 368(a) of the Code, the stockholders of Parker may be required to pay substantial U.S. federal income taxes.

The merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and Nabors and Parker shall report it as such for U.S. federal, state and local income tax purposes. While the obligation of Nabors and Parker to complete the merger is not conditioned upon the receipt by either of Nabors or Parker of a tax opinion from its counsel or any other counsel on the qualification of the merger as a “reorganization” within the meaning of Section 368(a) of the Code, Parker has obtained a tax opinion from its counsel, Akin Gump Strauss Hauer & Feld LLP, in the form included as Exhibit 8.1. Neither Nabors nor Parker intends to obtain a ruling from the IRS with respect to the tax consequences of the merger. Accordingly, there can be no assurances that the IRS will not assert, or that a court will not sustain, a position contrary to the one described here. If the IRS or a court determines that the merger should not be treated as a “reorganization” within the meaning of Section 368(a) of the Code, upon the exchange of Parker common stock for Nabors common shares pursuant to the merger, a holder of Parker common stock generally would recognize taxable gain or loss as if it sold its shares of Parker common stock. If, however, cash received by Parker stockholders in respect of their Parker common stock (e.g., from cash received if the Closing Price is lower than the Lower Collar Price, cash

33

received in connection with the disbursement of certain amounts received in connection with the Barge Rig Holdback Amount and cash received in lieu of fractional Nabors common shares) exceeds 20% of the total consideration received in respect of Parker common stock, then the merger is not expected to qualify as a “reorganization” within the meaning of Section 368(a) of the Code and the merger would be fully taxable to Parker stockholders. See “Material U.S. Federal Income Tax Consequences”.

The business relationships of Nabors and Parker may be subject to disruption due to uncertainty associated with the merger, which could have a material adverse effect on the results of operations, cash flows and financial position of Nabors or Parker pending and following the merger.

Parties with which Nabors and Parker do business may experience uncertainty associated with the merger, including with respect to current or future business relationships with the combined company following the merger. Nabors’ and Parker’s business relationships may be subject to disruption as customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners may attempt to delay or defer entering into new business relationships, negotiate changes in existing business relationships or consider entering into business relationships with parties other than Nabors or Parker prior to or following the merger. These disruptions could have a material and adverse effect on the results of operations, cash flows and financial position of Nabors or Parker, regardless of whether the merger is completed, as well as a material and adverse effect on Nabors’ ability to realize the expected cost savings and other benefits of the merger. The risk, and adverse effect, of any disruption could be exacerbated by a delay in completion of the merger or termination of the merger agreement.

The merger agreement subjects Nabors and Parker to restrictions on their respective business activities prior to the effective time.

The merger agreement subjects Nabors and Parker to restrictions on their respective business activities prior to the effective time. The merger agreement obligates each of Nabors and Parker to use its commercially reasonable efforts to carry on its business in the ordinary course in all material respects, and the merger agreement obligates each of Nabors and Parker to use its commercially reasonable efforts to conduct its business in the ordinary course of business in all material respects and preserve substantially intact its present business organization, except as otherwise expressly contemplated by the merger agreement. These restrictions could prevent Nabors and Parker from pursuing certain business opportunities that arise prior to the effective time and are outside the ordinary course of business.

Nabors and Parker are expected to incur significant transaction costs in connection with the merger, which may be in excess of those anticipated by them.

Nabors and Parker have incurred and are expected to continue to incur significant non-recurring costs associated with negotiating and completing the merger, combining the operations of the two companies and achieving desired synergies. These costs have been, and will continue to be, substantial and, in many cases, will be borne by Nabors and Parker whether or not the merger is completed. A substantial majority of non-recurring expenses will consist of transaction costs and include, among others, fees paid to financial, legal, accounting and other advisors, employee retention, severance and benefit costs and filing fees. Nabors will also incur costs related to formulating and implementing integration plans, including facilities and systems consolidation costs and other employment-related costs. Nabors and Parker will continue to assess the magnitude of these costs, and additional unanticipated costs may be incurred in connection with the merger and the integration of the two companies’ businesses. While Nabors and Parker have assumed that a certain level of expenses would be incurred, there are many factors beyond their control that could affect the total amount or the timing of the expenses. The elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, may not offset integration-related costs and achieve a net benefit in the near term, or at all. The costs described above and any unanticipated costs and expenses, many of which will be borne by Nabors and Parker even if the merger is not completed, could have an adverse effect on Nabors’ or Parker’s financial condition and operating results.

34

Litigation relating to the merger could result in an injunction preventing the completion of the merger and/or substantial costs to Nabors and Parker.

Securities class action lawsuits and derivative lawsuits are often brought against companies that have entered into acquisition, merger, or other business combination agreements. Even if such a lawsuit is without merit, defending against these claims can result in substantial costs and divert management time and resources. An adverse judgment could result in monetary damages, which could have a negative impact on Nabors’ and Parker’s respective liquidity and financial condition.

Lawsuits that have been or may be brought against Nabors, Parker or their respective directors could also seek, among other things, injunctive relief or other equitable relief, including a request to rescind parts of the merger agreement already implemented and to otherwise enjoin the parties from consummating the merger. One of the conditions to the closing of the merger is that no law or governmental order is in effect that restrains, enjoins, makes illegal or otherwise prohibits the closing of the merger. Consequently, if a plaintiff is successful in obtaining an injunction prohibiting completion of the merger, that injunction may delay or prevent the merger from being completed within the expected timeframe or at all, which may adversely affect Nabors’ and Parker’s respective business, financial position and results of operation. Either Nabors or Parker may terminate the merger agreement if any governmental order permanently restraining, enjoining or otherwise prohibiting the consummation of the transactions becomes final and nonappealable, so long as the party seeking to terminate the merger agreement has used its reasonable best efforts prevent the entry of and to remove such governmental order in accordance with the terms of the merger agreement.

There can be no assurance that any of the defendants will be successful in the outcome of any current or future lawsuits. The defense or settlement of any lawsuit or claim that remains unresolved at the time the merger is completed may adversely affect Nabors’ or Parker’s business, financial condition, results of operations and cash flows.

The merger may be completed even though material adverse changes subsequent to the announcement of the merger, such as industry-wide changes or other events, may occur.

In general, either party can refuse to complete the merger if there is a material adverse change affecting the other party. However, some types of changes do not permit either party to refuse to complete the transaction, even if such changes would have a material adverse effect on either of the parties. For example, a worsening of Nabors’ or Parker’s financial condition or results of operations due to a decrease in commodity prices or general economic conditions would not give the other party the right to refuse to complete the merger. In addition, the parties have the ability, but are under no obligation, to waive any material adverse change that results in the failure of a closing condition and instead proceed with completing the merger. If adverse changes occur that affect either party, but the parties are still required or voluntarily decide to complete the transaction, Nabors’ share price, business and financial results after the merger may suffer.

Risk Factors Relating to the Combined Company Following the Merger

The combined company’s debt may limit its financial flexibility.

As of November 26, 2024, Nabors had outstanding borrowings of $51.5 million in letters of credit outstanding under its credit facility. In connection with the consummation of the merger, Nabors currently intends to repay Parker’s outstanding indebtedness and to fund all or a portion of the repayment with a mixture of cash on hand and borrowings under Nabors’ existing credit facility and other such financing instruments such as term loans. As of September 30, 2024, Parker had a total of $177.8 million in principal amount of the Term Loan (as defined below) outstanding under its Term Loan Credit Agreement (as defined below); as of such date, Parker had no outstanding borrowings under its ABL Credit Facility (as defined below) and $14.7 million in letters of credit outstanding under such facility. In addition, the combined company may incur additional debt from time to

35

time in connection with the financing of operations, acquisitions, recapitalizations and refinancings. The level of the combined company’s debt could have several important effects on future operations, including, among others:

The failure to integrate successfully the businesses of Nabors and Parker in the expected timeframe or to effectively manage the consolidated company post-merger would adversely affect the combined company’s future results following the merger.

The merger involves the integration of two companies that currently operate independently. The success of the merger will depend—in large part—on the ability of the combined company to realize the anticipated benefits, including expected synergies, cost savings, increased innovation and operational efficiencies, from combining the businesses of Nabors and Parker. To realize these anticipated benefits, the businesses of Nabors and Parker must be successfully integrated. This integration will be complex and time-consuming. The failure to integrate successfully and to manage successfully the challenges presented by the integration process may result in the combined company not achieving the anticipated benefits of the merger.

Potential difficulties that may be encountered in the integration process include the following:

36

Any of these difficulties in successfully integrating the businesses of Nabors and Parker, or any delays in the integration process, could adversely affect the combined company’s ability to achieve the anticipated benefits of the merger and could adversely affect the combined company’s business, financial results, financial condition and stock price. Even if the combined company is able to integrate the business operations of Nabors and Parker successfully, there can be no assurance that this integration will result in the realization of the full benefits of synergies, cost savings, increased innovation and operational efficiencies that Nabors and Parker currently expect from this integration or that these benefits will be achieved within the anticipated time frame or that these benefits will match Nabors’ or Parker’s current expectations. Following integration, the combined company’s future success will depend on its ability to manage its operations, which will be significantly larger than the size of either Nabors’ or Parker’s existing businesses. The failure to successfully integrate the two companies, to realize the expected benefits of the merger, or to manage the consolidated company’s operations, could have an adverse effect on the combined company.

The future results of the combined company will suffer if the combined company does not effectively manage its expanded operations following the merger.

Following the merger, the size of the business of the combined company will increase significantly beyond the current size of either Nabors’ or Parker’s business. The combined company’s future success depends, in part, upon its ability to manage this expanded business, which will pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. There can be no assurances that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings, revenue enhancements and other benefits currently anticipated from the merger.

The combined company is expected to incur substantial expenses related to the merger and the integration of Nabors and Parker.

The combined company is expected to incur substantial expenses in connection with the merger and the integration of Nabors and Parker. There are many processes, policies, procedures, operations, technologies and systems that must be integrated, including accounting and finance, asset management, benefits, billing, drilling data solutions, health, safety and environment, human resources, maintenance, marketing, payroll and purchasing. While Nabors and Parker have assumed that a certain level of expenses will be incurred, there are many factors beyond their control that could affect the total amount or the timing of the integration expenses. Moreover, many of the expenses that will be incurred are, by their nature, difficult to estimate accurately. These expenses could, particularly in the near term, exceed the savings that the combined company expects to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings. These integration expenses could result in the combined company’s taking charges against earnings following the completion of the merger, and the amount and timing of any such charges are uncertain at present.

The merger may result in a loss of customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners and may result in the modification or termination of existing contracts.

Following the merger, some of the customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners of Nabors or Parker may modify, terminate or scale back their current or prospective business relationships with the combined company. Some customers may not wish to source a larger percentage of their needs from a single company or may feel that the combined company is too closely allied with one of their competitors. In addition, Nabors and Parker have contracts with customers, distributors, suppliers, vendors,

37

landlords, joint venture partners and other business partners that may require Nabors or Parker to obtain consents from these other parties in connection with the merger, which may not be obtained on favorable terms or at all. If relationships with customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners are adversely affected by the merger, or if the combined company loses the benefits of the contracts of Nabors or Parker, the combined company’s business, financial condition, results of operations and cash flows could suffer.

The unaudited prospective financial information for Nabors and Parker included in this joint proxy statement/prospectus reflects management estimates and may not prove to be reflective of actual future results.

In connection with the merger, Nabors and Parker prepared and considered, among other things, certain internal, unaudited prospective financial information for Nabors and Parker, respectively. This unaudited prospective financial information included assumptions regarding future operating cash flows, expenditures and growth of Nabors and Parker. This internal, unaudited prospective financial information speaks only as of the date made and, except as required by applicable securities laws, will not be updated. This unaudited prospective financial information is subject to significant economic, competitive, industry and other uncertainties, including the factors described under “Risk Factors” and “Special Note Regarding Forward-Looking Statements”, which factors and uncertainties may cause the unaudited prospective financial information or the underlying assumptions to be inaccurate. As a result of these contingencies, there can be no assurance that the unaudited prospective financial information of Nabors and Parker will be achieved in full, at all or within projected timeframes. In view of these uncertainties, the inclusion of the unaudited prospective financial information of Nabors and Parker in this joint proxy statement/prospectus should not be regarded as an indication that the board of directors of Nabors or Parker, Nabors, Parker, Merger Sub, or any other recipient of this information considered, or now considers, it to be an assurance of the achievement of future results.

The unaudited prospective financial information was not prepared with a view toward public disclosure or toward compliance with published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation or presentation of prospective financial information. The unaudited prospective financial information included in this document has been prepared by, and is the responsibility of, the Nabors and Parker management teams. PricewaterhouseCoopers LLP has not audited, reviewed, examined, compiled nor applied agreed-upon procedures with respect to the accompanying unaudited prospective financial information and, accordingly, PricewaterhouseCoopers LLP does not express an opinion or any other form of assurance with respect thereto. The PricewaterhouseCoopers LLP reports incorporated by reference in this document regarding Nabors and included herein regarding Parker relate to Nabors’ and Parker’s previously issued financial statements. They do not extend to the unaudited prospective financial information and should not be read to do so. Neither PricewaterhouseCoopers LLP, the independent registered public accounting firm for Nabors and Parker, nor any other independent registered public accounting firm has examined, or performed any procedures with respect to the unaudited prospective financial information.

The unaudited pro forma financial information included in this document is presented for illustrative purposes only and may not be an indication of the combined company’s financial condition or results of operations following the merger.

The unaudited pro forma financial information contained in this document is presented for illustrative purposes only, is based on various adjustments, assumptions and preliminary estimates and may not be an indication of the combined company’s financial condition or results of operations following the merger for several reasons. The actual financial condition and results of operations of the combined company following the merger may not be consistent with—or evident from—this unaudited pro forma financial information. In addition, the assumptions used in preparing the unaudited pro forma financial information may prove to be inaccurate, and other factors may affect the combined company’s financial condition or results of operations following the merger. Any potential decline in the combined company’s financial condition or results of operations may cause significant variations in the stock price of the combined company. See “Unaudited Pro Forma Condensed Combined Financial Statements”.

38

Uncertainty about the merger and diversion of management could harm the combined company following the merger.

The combined company’s success will be dependent upon the experience and industry knowledge of its officers and other key employees. The merger could result in current and prospective employees’ experiencing uncertainty about their future with the combined company following the merger. These uncertainties may impair the ability of the combined company to retain, recruit or motivate key personnel. In addition, completion of the merger and integrating the companies’ operations will require a significant amount of time and attention from management of the two companies. The diversion of management’s attention away from ongoing operations could adversely affect business relationships of the combined company following the merger.

Uncertainties associated with the merger may cause a loss of key employees, which could adversely affect the future business and operations of the combined company.

Nabors and Parker are dependent on the experience and industry knowledge of their officers and other key employees to execute their business plans. Each company’s success until the merger and the combined company’s success after the merger will depend in part upon the ability of Nabors and Parker to retain key employees. Current and prospective employees of Nabors and Parker may experience uncertainty about their roles within the combined company following the merger, which may have an adverse effect on the ability of each of Nabors and Parker to attract or retain key personnel. Accordingly, no assurance can be given that the combined company will be able to attract or retain key employees of Nabors and Parker to the same extent that Nabors and Parker have previously been able to attract or retain their own employees.

The market price of the combined company’s common shares may be volatile, and holders of the combined company’s common shares could lose a significant portion of their investment due to drops in the market price of the combined company’s common share following completion of the merger.

The market price of the combined company’s common shares may be volatile due to factors unrelated to the combined company’s operating performance or prospects. Specific factors that may have a significant effect on the market price for the combined company’s common shares include, among others, the following:

39

If, following the merger, large amounts of the combined company’s common shares are sold, the price could decline.

Business issues currently faced by Nabors or Parker may be imputed to the operations of the other.

To the extent that either Nabors or Parker currently has or is perceived by customers to have operational challenges, such as service performance, safety issues or workforce issues, those challenges may raise concerns by existing customers of the other company following the merger, which may limit or impede the combined company’s future ability to obtain additional work from those customers.

The combined company may not be able to utilize a portion of Nabors’ or Parker’s net operating loss carry forwards (“NOLs”) to offset future taxable income for U.S. federal tax purposes, which could adversely affect the combined company’s net income and cash flows.

As of September 30, 2024, Parker had federal income tax NOLs of approximately $28.0 million, net of estimated cancellation of indebtedness income and Section 382 limitations, which will expire between 2035 and 2037, and $19.1 million have an indefinite life. As of September 30, 2024, Nabors had federal income tax NOLs of approximately $559.3 million, all of which have an indefinite life. Utilization of these NOLs depends on many factors, including the combined company’s future taxable income, which cannot be predicted with any accuracy. In addition, Section 382 of the Code generally imposes an annual limitation on the amount of an NOL that may be used to offset taxable income when a corporation has undergone an “ownership change” (as determined under Section 382). Determining the limitations under Section 382 is technical and highly complex. An ownership change generally occurs if one or more shareholders (or groups of shareholders) who are each deemed to own at least 5% of the corporation’s stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. For these reasons, the combined company may not be able to realize a material portion of Parker’s NOLs, which could result in the combined company facing increased future tax liability.

Fluctuations in oil and natural gas prices could adversely affect drilling, completion and production activities by oil and natural gas companies and the combined company’s valuation, revenues, cash flows and profitability.

Following the completion of the merger, the combined company’s operations, demand for its services, and the rates it will be able to charge for such services depend on the level of spending by oil and gas companies for exploration, development and production activities. Both short-term and long-term trends in oil and natural gas prices affect these activity levels. Oil and natural gas prices, as well as the level of drilling, exploration and production activity, have been highly volatile for several years and are expected to continue to be volatile for the

foreseeable future. Declines in oil prices are primarily caused by, among other things, an excess of supply of crude oil in relation to demand, in addition to significant shocks to regional and global economies such as the COVID-19 pandemic and regional and global conflicts, especially in significant oil-producing regions around the world. Worldwide military, political, public health, and economic events, including initiatives by the Organization of Petroleum Exporting Countries (“OPEC”) and OPEC+, uncertainty in capital and commodities markets, and the ability of oil and natural gas producers to access capital, and the extent to which they are willing or able to deploy capital, affect both the supply of and demand for oil and natural gas. In addition, weather conditions, governmental regulation (both in the United States and elsewhere) related to the development/production and use of oil and natural gas, levels of consumer demand for oil and natural gas, general and global economic conditions, oil and gas production levels by non-OPEC countries, decisions by oil and gas producers to continue producing oil and gas despite excess supply, the availability and demand for drilling equipment and pipeline capacity, availability and pricing of alternative energy sources, as well as governmental programs that incentivize the use of alternative energy, public perception of fossil fuel use and other factors beyond our control may also affect the supply of and demand for oil and natural gas, and thereby affect the price of oil and natural gas.

40

Lower oil and natural gas prices also could adversely affect our cash forecast models used to determine whether the carrying values of our long-lived assets exceed our future cash flows, which could result in future impairment to our long-lived assets. Lower oil and natural gas prices also could affect our ability to retain skilled rig personnel and affect our ability to access capital to finance and grow our business. There can be no assurances as to the future level of demand for our services or future conditions in the oil and natural gas and oilfield services industries.

Risk Factors Relating to Nabors

Nabors’ business is and will be subject to the risks described in Nabors’ Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as such risks may be updated or supplemented in its subsequently filed Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, to the extent incorporated by reference into this joint proxy statement/prospectus. See “Where You Can Find More Information”.

Risk Factors Relating to Parker

As a result of entering into the merger agreement, Parker’s business is and will be subject to the risks described above. In addition, following completion of the merger, the combined company will be subject to the following risks:

Parker’s business and financial performance depends primarily upon the general level of activity in the oil and natural gas industry, and therefore, volatility of prices for oil and natural gas has had, and may continue to have, a material adverse effect on its financial condition, results of operations, and cash flows.

Oil and natural gas prices and market expectations regarding potential changes in these prices are volatile and are likely to continue to be volatile in the future. Increases or decreases in oil and natural gas prices and expectations of future prices could have an impact on Parker’s customers’ long-term exploration and development activities, which in turn could materially affect its business and financial performance. Furthermore, higher oil and natural gas prices do not necessarily result immediately in increased drilling activity because Parker’s customers’ expectations of future oil and natural gas prices typically drive demand for its drilling services. The oil and natural gas industry has historically experienced periodic downturns, which have been characterized by diminished demand for oilfield services and downward pressure on the prices Parker charges. A prolonged downturn in the oil and natural gas industry could result in a further reduction in demand for oilfield services and could continue to adversely affect Parker’s financial condition, results of operations, and cash flows. Oil and natural gas prices and demand for Parker’s services also depend upon numerous factors which are beyond its control, including:

41

Demand for the majority of Parker’s services is substantially dependent on the levels of expenditures by the oil and natural gas industry. A substantial or an extended decline in oil and natural gas prices could result in lower expenditures by the oil and natural gas industry, which could have a material adverse effect on Parker’s financial condition, results of operations, and cash flows.

Demand for the majority of Parker’s services depends substantially on the level of expenditures for the exploration, development, and production of oil or natural gas reserves by the major, independent, and national oil and natural gas E&P companies and large integrated service companies that comprise Parker’s customer base. These expenditures are generally dependent on the industry’s view of future oil and natural gas prices and are sensitive to the industry’s view of future economic growth and the resulting impact on demand for oil and natural gas, including a heightened emphasis by E&P companies’ investors demanding cash flow returns which can limit the number of wells being drilled. For example, prolonged low commodity prices experienced by the oil and natural gas industry during 2015, 2016 and 2020, combined with adverse changes in the capital and credit markets, caused many exploration and production companies to reduce their capital budgets and drilling activity. This led to decreased utilization and dayrates and a reduction or discontinuation of drilling levels, causing an oversupply of drilling rigs. Future declines in oil and natural gas prices may similarly result in project modifications, delays or cancellations, general business disruptions, and delays in payment of, or nonpayment of, amounts that are owed to Parker, any of which could have a material adverse effect on its financial condition, results of operations, and cash flows.

Failure to comply with anti-corruption laws, such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act 2010, could result in fines, criminal penalties, negative commercial consequences and an adverse effect on Parker’s business.

The U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act 2010, and similar anti-corruption laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments or providing improper benefits for the purpose of obtaining or retaining business, directing business to any person or corporate entity, or obtaining any unfair advantage. Parker’s policies mandate compliance with these anti-corruption laws. However, Parker operates in many parts of the world that experience corruption, and its activities create the risk of unauthorized payments or offers of payments by its employees or agents that could be in violation of anti-corruption laws, even though some of these parties are not subject to Parker’s control. If Parker is found to be liable for violations of these laws either due to its own acts or omissions or due to the acts or omissions of others (including its joint ventures partners, its agents or other third-party representatives), it could suffer from severe commercial, civil, and criminal penalties or other sanctions, which could have a material adverse effect on its business, financial condition, and results of operations. In addition, any major violations could have a significant effect on Parker’s reputation and consequently on its ability to win future business and maintain existing customer and supplier relationships.

Parker’s international operations are subject to governmental regulation and other risks.

Parker derives a significant portion of its revenues from its international operations. For the year ended December 31, 2023, Parker derived approximately 31.5 percent of its revenues from operations in countries other than the United States. For the nine months ended September 30, 2024, Parker derived approximately 39.2 percent of its revenues from operations in countries other than the United States. Parker’s international operations are subject to the following risks, among others:

43

Parker currently has operations in 14 countries. Parker’s operations are subject to interruption, suspension, and possible expropriation due to terrorism, war, civil disturbances, political and capital instability, and similar events, and it has previously suffered loss of revenues and damage to equipment due to political violence. Civil and political disturbances in international locations may affect Parker’s operations. Parker may not be able to obtain insurance policies covering risks associated with these types of events, especially political violence coverage, and such policies may only be available with premiums that are not commercially reasonable.

Parker’s international operations are subject to the laws and regulations of a number of countries with political, regulatory and judicial systems and regimes that may differ significantly from those in the U.S. Parker’s ability to compete in international contract drilling and rental tool services markets may be adversely affected by foreign governmental regulations and/or policies that favor the awarding of contracts to contractors in which nationals of those foreign countries have substantial ownership interests or by regulations requiring foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. Furthermore, Parker’s foreign subsidiaries may face governmentally imposed restrictions or fees from time to time on the transfer of funds to itself.

In addition, tax and other laws and regulations in some foreign countries are not always interpreted consistently among local, regional, and national authorities, which can result in disputes between Parker and governing authorities. The ultimate outcome of these disputes is never certain, and it is possible that the outcomes could have an adverse effect on Parker’s financial performance.

A portion of the workers Parker employs in its international operations are members of labor unions or otherwise subject to collective bargaining. Parker may not be able to hire and retain a sufficient number of skilled and experienced workers for wages and other benefits that it believes are commercially reasonable.

Parker may experience currency exchange losses where revenues are received or expenses are paid in nonconvertible currencies or where it does not take protective measures against exposure to a foreign currency. Parker may also incur losses as a result of an inability to collect revenues because of a shortage of convertible currency available to the country of operation, controls over currency exchange, or controls over the repatriation of income or capital. Given the international scope of Parker’s operations, Parker is exposed to risks of currency fluctuation and restrictions on currency repatriation. Parker attempts to limit the risks of currency fluctuation and restrictions on currency repatriation where possible by obtaining contracts payable in U.S. dollars or freely convertible foreign currency. In addition, some parties with which Parker does business could require that all or a portion of its revenues be paid in local currencies. Foreign currency fluctuations, therefore, could have a material adverse effect upon Parker’s results of operations and financial condition.

The shipment of goods, services and technology across international borders subjects Parker to extensive trade laws and regulations. Parker’s import activities are governed by the unique customs laws and

44

regulations of each of the countries where it operates. Moreover, many countries, including the U.S., control the export and re-export of certain goods, services, and technology and impose related export recordkeeping and reporting obligations. The laws and regulations concerning import activity, export recordkeeping and reporting, export control, and economic sanctions are complex and constantly changing. These laws and regulations can cause delays in shipments, unscheduled operational downtime and other operational disruptions. Moreover, any failure to comply with applicable legal and regulatory trading obligations could result in criminal and civil penalties and sanctions, such as fines, imprisonment, debarment from governmental contracts, seizure of shipments, and loss of import and export privileges. Reputational damage can also result from any failure to comply with such obligations.

Parker’s business, financial condition and results of operations may be affected by economic sanctions and export controls, including those targeting Russia.

During 2014, the United States, the European Union, the United Kingdom and certain other countries imposed sanctions on certain sectors of the Russian economy, and on certain individuals and entities, and additional sanctions have been imposed since 2014, including with respect to the energy sector. In response to Russia’s military action in Ukraine in 2022, the United States, the European Union and the United Kingdom, among others, have imposed significant economic sanctions and export control measures on Russia and others supporting Russia’s military and political actions in Ukraine, including blocking or “asset freezing” sanctions on designated entities and individuals; restrictions on the Russian energy and financial sectors; blocking economic activity in certain areas of Ukraine not controlled by the Ukrainian government; prohibitions in relation to investment in Russia; prohibitions and restrictions relating to Russian origin oil and oil products; and export controls limiting the export of a wide range of goods and technical assistance to Russia. In response, Russia has implemented counter-sanctions, including restrictions on the divestment from Russian assets by foreign investors and restrictions on the payments of dividends and transfers of funds out of Russia by foreign investors. Existing and future economic sanctions, export controls, import controls and other measures, as well as the existing and potential further responses from Russia or other countries to such economic sanctions, and further tensions and military actions, could adversely affect the global economy and financial markets and could adversely affect Parker’s business, financial condition and results of operations.

The contract drilling and the rental tools services businesses are highly competitive and cyclical, with intense price competition.

The contract drilling and rental tools services markets are highly competitive and many of Parker’s competitors in both the contract drilling and rental tools services businesses may possess greater financial resources than Parker does. Some of Parker’s competitors are incorporated in countries that may provide them with significant tax advantages that are not available to Parker as a U.S. company and which may impair its ability to compete with them for many projects.

Contract drilling companies compete primarily on a regional basis, and competition may vary significantly from region to region at any particular time. Many drilling and workover rigs and drilling-related rental tools can be moved from one region to another in response to changes in levels of activity, provided market conditions warrant, which may result in an oversupply of rigs and rental tools in an area. Many competitors construct rigs during periods of high energy prices and, consequently, the number of rigs available in some of the markets in which Parker operates can exceed the demand for rigs for extended periods of time, resulting in intense price competition. Most drilling contracts are awarded on the basis of competitive bids, which also results in price competition.

Historically, the drilling and rental tools services industry has been highly cyclical, with periods of high demand, limited equipment supply and high dayrates often followed by periods of low demand, excess equipment supply and low dayrates. Periods of low demand and excess equipment supply intensify the competition in the industry and often result in equipment being idle for long periods of time. During periods of

45

decreased demand, Parker typically experiences significant reductions in dayrates and utilization. Parker, or its competition, may move rigs or other equipment such as rental tools from one geographic location to another location, the cost of which may be substantial. If Parker experiences decreases in dayrates, inability to increase or even maintain its market share, or if it cannot keep its equipment utilized, its financial performance will be adversely impacted. Prolonged periods of low utilization, decreased market share, and lower dayrates could result in the recognition of impairment charges on certain of Parker’s rigs if future cash flow estimates, based upon information available to management at the time, indicate that the carrying value of these rigs may not be recoverable.

Parker must renew customer contracts to remain competitive.

Parker’s ability to renew existing customer contracts, or obtain new contracts, and the terms of any such contracts depends on market conditions and its customers’ future drilling plans, which are subject to change. Due to the highly competitive nature of the industry, which can be exacerbated during periods of depressed market conditions, Parker may not be able to renew or replace expiring contracts or, if it is able to, it may not be able to secure or improve existing dayrates or other material terms, which could have an adverse effect on its business, financial condition and results of operations.

Rig upgrade, refurbishment and construction projects are subject to risks and uncertainties, including delays and cost overruns, which could have an adverse impact on Parker’s results of operations and cash flows.

Parker regularly makes significant expenditures in connection with upgrading and refurbishing its rig fleet. These activities include planned upgrades to maintain quality standards, routine maintenance and repairs, changes made at the request of customers, and changes made to comply with environmental or other regulations. Rig upgrade, refurbishment, and construction projects are subject to the risks of delay or cost overruns inherent in any large construction project, including the following:

46

Any one of the above risks could adversely affect Parker’s financial condition and results of operations. Delays in the delivery of rigs being constructed or undergoing upgrade, refurbishment, or repair may, in many cases, delay commencement of a drilling contract resulting in a loss of revenues to Parker, and may also cause its customer to renegotiate the drilling contract for the rig or terminate or shorten the term of the contract under applicable late delivery clauses, if any. If one of these contracts is terminated, Parker may not be able to secure a replacement contract on as favorable terms, if at all. Additionally, actual expenditures for required upgrades or to refurbish or construct rigs could exceed Parker’s planned capital expenditures, impairing its ability to service its debt obligations.

The change of Parker’s management and other personnel may reduce Parker’s competitiveness and harm prospects for future success.

Following the completion of the merger, it is anticipated that some of Parker’s present management and other personnel will no longer be employed by Parker or will remain with Parker in substantially different roles. The loss of Parker’s personnel and transition of new personnel could reduce its competitiveness and harm prospects for future success, which may adversely affect its business, financial condition and results of operations.

Failure to attract and retain skilled and experienced personnel could affect Parker’s operations.

Parker requires skilled, trained, and experienced personnel to provide its customers with the highest quality technical services and support for its drilling operations. Parker competes with other oilfield services businesses and other employers to attract and retain qualified personnel with the technical skills and experience it requires. Competition for skilled labor and other labor required for Parker’s operations intensifies as the number of rigs activated or added to worldwide fleets or under construction increases, creating upward pressure on wages. In periods of high utilization, Parker has found it more difficult to find and retain qualified individuals. A shortage in the available labor pool of skilled workers or other general inflationary pressures or changes in applicable laws and regulations could make it more difficult for Parker to attract and retain personnel and could require Parker to enhance its wage and benefits packages. Increases in Parker’s operating costs could adversely affect its business and financial results. Moreover, the shortages of qualified personnel or the inability to obtain and retain qualified personnel could negatively affect the quality, safety, and timeliness of Parker’s operations.

Increased scrutiny and changing stakeholder expectations with respect to environmental, social and governance (“ESG”) matters may impact Parker’s business and expose Parker to additional risks.

In recent years, companies across all industries are facing increasing scrutiny from stakeholders related to their ESG and sustainability practices. Failure or a perception (whether or not valid) of failure to implement an ESG strategy or achieve sustainability goals Parker has set could damage its reputation, causing its stakeholders to lose confidence in Parker, and negatively impact its operations. There can be no assurance that Parker will be able to accomplish any announced goals, initiatives, commitments or objectives related to its ESG strategy, as statements regarding the same reflect its current plans and aspirations and are not guarantees that Parker will be able to achieve them within the timelines it announces, or at all.

47

Further, Parker’s business and growth opportunities require it to have strong relationships with various key stakeholders, including its stockholders, employees, suppliers, customers, local communities and others. Parker may face pressures from stakeholders, many of whom are increasingly focused on climate change, to prioritize sustainable energy practices, reduce its carbon footprint and promote sustainability while at the same time remaining a successfully operating public company. If Parker does not successfully manage expectations across these varied stakeholder interests, it could erode Parker’s stakeholder trust and thereby affect its brand and reputation. Such erosion of confidence could negatively impact Parker’s business through decreased demand and growth opportunities, delays in projects, increased legal action and regulatory oversight, adverse press coverage and other adverse public statements, difficulty hiring and retaining top talent, difficulty obtaining necessary approvals and permits from governments and regulatory agencies on a timely basis and on acceptable terms and difficulty securing investors and access to capital.

New technologies may cause Parker’s drilling methods and equipment to become less competitive and it may become necessary to incur higher levels of operating and capital expenditures in order to keep pace with the disruptive trends in the drilling industry. Growth through the building of new drilling rigs and improvement of existing rigs is not assured.

The market for Parker’s services is characterized by continual technological developments that have resulted in, and will likely continue to result in, substantial improvements in the functionality and performance of rigs and equipment. Parker’s customers increasingly demand the services of newer, higher specification drilling rigs and related equipment. Accordingly, Parker may have to allocate a higher proportion of its capital expenditures to improve the technological aspects of its existing rigs and other equipment, purchase and construct newer, higher specification drilling rigs and other equipment to meet the increasingly sophisticated needs of its customers and develop new and improved technology and data analytics.

Although a component of Parker’s strategy is to develop and use advanced oil and natural gas drilling technology, changes in technology or improvements on existing technology by competitors could make its equipment less competitive. There can be no assurance that Parker will:

If Parker is successful in developing new technologies for use in its business, there is no guarantee of future demand for those technologies. Customers may be financially incapable or otherwise reluctant or unwilling to adopt Parker’s new technologies or may choose competing technologies. Parker may also have difficulty negotiating satisfactory terms for its technology services or may be unable to secure prices sufficient to obtain expected returns on its investment in the research and development of new technologies.

48

Furthermore, Parker expects its competitors to continue to improve their own technology systems. Such improvements could potentially allow Parker’s competitors to improve their drilling efficiency and service quality. Parker’s ability to continue to innovate its own technology infrastructure and appropriately anticipate and address its customers’ needs will affect its ability to compete.

Development of new technology is critical to maintaining Parker’s competitiveness. There can be no assurance that Parker will be able to successfully develop technology that its customers demand. If Parker is not successful in keeping pace with technological advances and trends (including trends in favor of emissions-reducing technologies) or if Parker fails to deliver such technologies to its customers in a timely and cost-effective manner suitable to their needs, demand for its services could decline and Parker could lose market share. Furthermore, if Parker’s equipment or proprietary technologies become obsolete, the value of its intellectual property may be reduced, or one or more technologies that Parker may implement in the future may not work as it expects and its business, financial condition, results of operations and reputation could be adversely affected as a result. If competing technologies are viewed as superior to Parker’s, it could affect Parker’s competitiveness. Additionally, new technologies, services or standards could render some of Parker’s services, drilling rigs or equipment obsolete, which could reduce its competitiveness and have a material adverse effect on its business, financial condition and results of operations.

Limitations on Parker’s ability to obtain, maintain, protect or enforce its intellectual property rights, including its trade secrets, could cause a loss in revenues and any competitive advantage Parker holds.

There can be no assurance that the steps Parker takes to obtain, maintain, protect and enforce its intellectual property rights will be adequate. Some of Parker’s products or services, and the processes it uses to produce or provide them, have been granted patent protection, have patent applications pending, or are trade secrets. Parker’s business may be adversely affected when its patents are unenforceable, the claims allowed under its patents are not sufficient to protect its technology, its patent applications are denied, or its trade secrets are not adequately protected. Patent protection on some types of technology, such as software or machine learning processes, may not be available in certain countries in which Parker operates. Parker’s competitors may also be able to develop technology independently like Parker’s without infringing on its patents or gaining access to its trade secrets, which could adversely affect its financial condition, results of operations and cash flows.

Technology disputes could negatively affect Parker’s operations or increase its costs.

Parker’s services and products use proprietary technology and equipment, which can involve potential infringement of a third party’s rights, or a third party’s infringement of its rights, including patent rights. The majority of the intellectual property rights relating to Parker’s drilling rigs and related services are owned by Parker or certain of its supplying vendors. However, in the event that Parker or one of its customers or supplying vendors becomes involved in a dispute over infringement of intellectual property rights relating to equipment or technology owned or used by Parker, services performed by Parker or products provided by Parker, Parker may lose access to important equipment or technology or its ability to provide services or products, or Parker could be required to cease use of some equipment or technology or be forced to invest or develop replacement technologies to enhance its equipment, technology, services or products. Parker could also be required to pay license fees or royalties for the use of equipment or technology or provision of services or products. In addition, Parker may lose a competitive advantage in the event it is unsuccessful in enforcing its rights against third parties. Regardless of the merits, any such claims generally result in significant legal and other costs, including reputational harm, and may distract management from running Parker’s business. Technology disputes involving Parker or its customers or supplying vendors could have a material adverse effect on its business, financial condition, cash flows and results of operations.

49

Improvements in or new discoveries of alternative energy technologies could have a material adverse effect on Parker’s financial condition and results of operations.

Since Parker’s business depends on the level of activity in the oil and natural gas industry, any improvement in or new discoveries of alternative energy technologies that increase the effectiveness (economic or otherwise), use or availability of alternative forms of energy and reduce the demand for oil and natural gas could have a material adverse effect on its business, financial condition and results of operations.

Parker’s current operations and future growth may require significant additional capital, and the amount and terms of its indebtedness could impair its ability to fund its capital requirements.

Parker’s business requires substantial capital. Parker may require additional capital in the event of growth opportunities, unanticipated maintenance requirements, or significant departures from its current business plan.

Additional financing may not be available on a timely basis or on terms acceptable to Parker and within the limitations contained in the ABL Credit Agreement and the Term Loan Credit Agreement or any other future debt agreements. Failure to obtain additional financing, should the need for it develop, could impair Parker’s ability to fund capital expenditure requirements and meet debt service requirements and could have an adverse effect on its business.

Parker has a significant amount of debt. Parker’s debt levels and debt agreement restrictions may have significant consequences for its future prospects, including limiting its liquidity and flexibility in obtaining additional financing or refinancing its existing high interest debt and in pursuing other business opportunities.

As of September 30, 2024, Parker had:

Parker’s ability to meet its debt service obligations depends on its ability to generate positive cash flows from operations. Parker has in the past, and may in the future, incur negative cash flows from one or more segments of its operating activities. Parker’s future cash flows from operating activities will be influenced by the demand for its drilling services, the utilization of its rigs, the dayrates that it receives for its rigs, demand for its rental tools, oil and natural gas prices, general economic conditions, and other factors affecting its operations, many of which are beyond its control.

If Parker is unable to service its debt obligations, it may have to take one or more of the following actions:

50

Despite Parker’s current level of indebtedness, it may still incur more debt. This could further exacerbate the risks associated with its indebtedness, including limiting its liquidity and its ability to pursue other business opportunities.

Parker may be able to incur additional indebtedness in the future, subject to certain limitations, including under the ABL Credit Facility and the Term Loan. If Parker incurs new debt on top of its existing debt, the related risks that it now faces could increase. Parker’s level of indebtedness could, for instance, prevent it from engaging in transactions that might otherwise be beneficial to it or from making desirable capital expenditures. This could put Parker at a competitive disadvantage relative to other less leveraged competitors that have more cash flow to devote to their operations. Additionally, Parker’s ABL Credit Facility provides, and any future credit facilities may provide, for variable interest rates, which may increase or decrease its interest expense. Furthermore, the incurrence of additional indebtedness could make it more difficult to satisfy Parker’s existing financial obligations.

Parker is subject to various covenants and events of default under the ABL Credit Facility and the Term Loan Credit Agreement. In general, certain of these covenants limit Parker’s ability, subject to certain exceptions, to take certain actions, including:

If Parker fails to comply with these covenants or an event of default occurs under the ABL Credit Agreement or the Term Loan Credit Agreement, its liquidity, financial condition or operations may be materially impacted.

Parker is subject to hazards customary for drilling operations, which could adversely affect its financial performance if it is not adequately indemnified or insured.

Substantially all of Parker’s operations are subject to hazards that are customary for oil and natural gas drilling operations, including blowouts, reservoir damage, loss of production, loss of well control, lost or stuck drill strings, equipment defects, cratering, oil and natural gas well fires and explosions, natural disasters, pollution, mechanical failure, and damage or loss during transportation. Some of Parker’s fleet is also subject to hazards inherent in marine operations, either while on-site or during mobilization, such as capsizing, sinking, grounding, collision, damage from severe weather, and marine life infestations. These hazards could result in damage to or destruction of drilling equipment, personal injury and property damage, suspension of operations, or environmental damage, which could lead to claims by third parties or customers, suspension of operations, and contract terminations. Parker has had accidents in the past due to some of these hazards. Typically, Parker is indemnified by its customers for injuries and property damage resulting from these types of events (except for injury to its employees and subcontractors and property damage to its and its subcontractors’ equipment). However, Parker could be exposed to significant loss if adequate indemnity provisions or insurance are not in place, if indemnity provisions are unenforceable or otherwise invalid, or if its customers are unable or unwilling to satisfy any indemnity obligations. Parker may not be able to insure against these risks or to obtain indemnification to adequately protect itself against liability from all of the consequences of the hazards and risks described above. The occurrence of an event not fully insured against or for which Parker is not indemnified, or the failure of a customer or insurer to meet its indemnification or insurance obligations, could result in substantial losses. In addition, insurance may not continue to be available to cover any or all of these risks. For

51

example, pollution, reservoir damage and environmental risks generally are not fully insurable. Even if such insurance is available, insurance premiums or other costs may rise significantly in the future, making the cost of such insurance prohibitive.

Certain areas in and near the Gulf of Mexico (“GOM”) are subject to hurricanes and other extreme weather conditions. When operating in and near the GOM, Parker’s drilling rigs and rental tools may be located in areas that could cause them to be susceptible to damage or total loss by these storms. In addition, damage caused by high winds and turbulent seas to Parker’s rigs, shore bases, and corporate infrastructure could potentially cause Parker to curtail operations for significant periods of time until the effects of the damage can be repaired. In addition, Parker’s rigs in arctic regions can be affected by seasonal weather so severe that conditions are deemed too unsafe for operations.

Parker is not fully insured against all risks associated with its business.

Parker ordinarily maintains insurance against certain losses and liabilities arising from its operations. However, Parker does not insure against all operational risks in the course of its business. Due to the high cost, high self-insured retention, and limited coverage for windstorms in the GOM Parker has elected not to purchase windstorm insurance for its inland barges in the GOM. Although Parker has retained the risk for physical loss or damage for these rigs arising from a named windstorm, it has procured insurance coverage for removal of a wreck caused by a windstorm. The occurrence of an event that is not fully covered by insurance could have a material adverse impact on Parker’s business activities, financial position, and results of operations.

Parker’s backlog of contracted revenues may not be fully realized and may reduce significantly in the future, which may have a material adverse effect on its financial position, results of operations, or cash flows.

Parker’s expected revenues under existing contracts (“contracted revenues”) may not be fully realized due to a number of factors, including rig or equipment downtime or suspension of operations. Several factors could cause downtime or a suspension of operations, many of which are beyond Parker’s control, including:

Liquidity issues could lead Parker’s customers to go into bankruptcy or could encourage its customers to seek to repudiate, cancel, or renegotiate its contracts for various reasons. Some of Parker’s contracts permit early termination of the contract by the customer for convenience (without cause), generally exercisable upon advance notice to Parker and in some cases without making an early termination payment to Parker. There can be no assurance that Parker’s customers will be able or willing to fulfill their contractual commitments to Parker.

Significant declines in oil prices, the perceived risk of low oil prices for an extended period, and the resulting downward pressure on utilization may cause some customers to consider early termination of select

52

contracts despite having to pay early termination fees in some cases. In addition, customers may request to re-negotiate the terms of existing contracts. Furthermore, as Parker’s existing contracts roll off, it may be unable to secure replacement contracts for its rigs, equipment or services. Therefore, revenues recorded in future periods could differ materially from Parker’s current contracted revenues, which could have a material adverse effect on its financial position, results of operations or cash flows.

Parker relies on third-party suppliers, manufacturers and service providers to secure equipment, components and parts used in rig operations, conversions, upgrades and construction.

Parker’s reliance on third-party suppliers, manufacturers and service providers to provide equipment and services exposes it to volatility in the quality, price and availability of such items. Certain components, parts and equipment that Parker uses in its operations may be available only from a small number of suppliers, manufacturers or service providers. The failure of one or more third-party suppliers, manufacturers or service providers to provide equipment, components, parts or services, whether due to capacity constraints, labor shortages or other labor-related difficulties, production or delivery disruptions, price increases, quality control issues, recalls or other decreased availability of parts and equipment, is beyond Parker’s control and could materially disrupt its operations or result in the delay, renegotiation or cancellation of drilling contracts, thereby causing a loss of contract drilling backlog and/or revenues, as well as an increase in operating costs.

Additionally, Parker’s suppliers, manufacturers, and service providers could be negatively affected by changes in industry conditions or global economic conditions. If certain of Parker’s suppliers, manufacturers or service providers were to curtail or discontinue their business as a result of such conditions, it could result in a reduction or interruption in supplies or equipment available to Parker and/or a significant increase in the price of such supplies and equipment, which could adversely affect its business, financial condition and results of operations. In addition, issues with the global supply chain, whether caused by the Ukraine/Russia conflict or other reasons, could make it more difficult for Parker’s suppliers to meet its requirements in a timely manner, if at all, which could ultimately result in an adverse effect on its operations.

Parker’s operating expense includes fixed costs that may not decline in proportion to decreases in rig utilization and dayrates.

Parker’s operating expense includes all direct and indirect costs associated with the operation, maintenance and support of its drilling and related equipment, many of which are not affected by changes in dayrates and some of which are not affected by utilization. During periods of reduced revenues and/or activity, certain of Parker’s fixed costs (such as depreciation) may not decline and often Parker may incur additional costs. During times of reduced utilization, reductions in costs may not be immediate as Parker may not be able to fully reduce the cost of its support operations in a particular geographic region due to the need to support the remaining drilling rigs in that region. Accordingly, a decline in revenues due to lower dayrates and/or utilization may not be offset by a corresponding decrease in drilling services and solutions expense, which could have a material adverse effect on Parker’s business, financial condition and results of operations.

Parker is exposed to counterparty credit risk. Nonpayment and nonperformance by Parker’s customers, suppliers or vendors could adversely impact its operations, cash flows and financial condition.

Weak economic conditions, volatility in the banking sector and/or widespread financial distress could reduce the liquidity of Parker’s customers, suppliers or vendors, making it more difficult for them to meet their obligations to Parker. Severe financial problems encountered by Parker’s customers, suppliers and vendors could limit its ability to collect amounts owed to Parker or to enforce the performance of obligations owed to Parker under contractual arrangements and/or limit its ability to enter into future contractual arrangements with such customers, suppliers or vendors. In the event that any of Parker’s customers were to enter into bankruptcy, Parker could lose all or a portion of the amounts owed to it by such customer, and it may be forced to cancel all or a portion of its contracts with such customer at a significant expense.

53

In addition, nonperformance by suppliers or vendors who have committed to provide Parker with critical products or services could raise its costs or interfere with its ability to successfully conduct its business. These factors, combined with volatile prices of oil and natural gas, may precipitate a continued economic slowdown and/or a recession.

Certain of Parker’s contracts are subject to cancellation by its customers without penalty and with little or no notice.

In periods of extended market weakness, Parker’s customers may not be able to honor the terms of existing contracts, may terminate contracts even where there may be onerous termination fees, or may seek to renegotiate contract dayrates and terms in light of depressed market conditions. Certain of Parker’s contracts are subject to cancellation by its customers without penalty and with relatively little or no notice. Significant declines in oil prices, the perceived risk of low oil prices for an extended period, and the resulting downward pressure on utilization may cause some customers to consider early termination of select contracts despite having to pay early termination fees in some cases. When drilling market conditions are depressed, a customer may no longer need a rig or rental tools currently under contract or may be able to obtain comparable equipment at lower dayrates. Further, due to government actions, a customer may no longer be able to operate in, or it may not be economical to operate in, certain regions. As a result, customers may leverage their termination rights in an effort to renegotiate contract terms.

Parker’s customers may also seek to terminate contracts for cause, such as the loss of or major damage to the drilling unit or other events that cause the suspension of drilling operations beyond a specified period of time. If Parker experiences operational problems or if its equipment fails to function properly and cannot be repaired promptly, its customers will not be able to engage in drilling operations and may have the right to terminate the contracts. If equipment is not timely delivered to a customer or does not pass acceptance testing, a customer may in certain circumstances have the right to terminate the contract. The payment of a termination fee may not fully compensate Parker for the loss of the contract. Early termination of a contract may result in a rig or other equipment being idle for an extended period of time. The likelihood that a customer may seek to terminate a contract is increased during periods of market weakness. The cancellation or renegotiation of a number of Parker’s contracts could materially reduce its revenues and profitability.

Service contracts with national oil companies may expose Parker to greater risks than it normally assumes in service contracts with non-governmental customers.

Parker currently provides services and owns rigs and other equipment that may be used in connection with projects involving national oil companies. In the future, Parker may expand its international operations and enter into additional, significant contracts or subcontracts relating to projects with national oil companies. The terms of these contracts may require Parker to resolve disputes in jurisdictions with less robust legal systems and may contain non-negotiable provisions and may expose Parker to greater commercial, political, environmental, operational, and other risks than it assumes in other contracts. These contracts may also expose Parker to materially greater environmental liability and other claims for damages (including consequential damages) and personal injury related to its operations, or the risk that the contract may be terminated by its customer without cause on short-term notice, contractually or by governmental action, or under certain conditions that may not provide Parker with an early termination payment. Parker can provide no assurance that increased risk exposure will not have an adverse impact on its future operations or that it will not increase the number of rigs or amount of equipment and services contracted to national oil companies with commensurate additional contractual risks. Risks that accompany contracts relating to projects with national oil companies could ultimately have a material adverse impact on Parker’s business, financial condition, and results of operation.

54

Parker derives a significant amount of its revenues from a few major customers. The loss of a significant customer could adversely affect Parker’s business, financial condition and results of operations.

A substantial percentage of Parker’s revenues are generated from a relatively small number of customers and the loss of a significant customer could adversely affect Parker. Parker’s largest customer accounted for approximately 13.6 percent of its consolidated revenues from continuing operations for the year ended December 31, 2023. Parker’s largest customer constituted approximately 15.6 percent of its consolidated revenue for the nine months ended September 30, 2024. Parker’s consolidated results of operations could be adversely affected if any of its significant customers terminate their contracts with Parker, fail to renew its existing contracts, or do not award new contracts to Parker. Replacing significant customers is difficult, and it is unlikely Parker would be able to replace such a loss in revenue from a single or a few larger customers. The loss of one or more of its larger customers could have a material adverse effect on Parker’s business, financial condition, results of operations and ability to meet its obligations. In addition, if a significant customer experiences liquidity constraints or other financial difficulties it may be unable to make required payments to Parker or seek to renegotiate contracts, which could adversely affect its liquidity and profitability. Financial difficulties experienced by customers could also adversely affect Parker’s utilization rates in the affected market and may cause its counterparties to seek modifications to its contracts with them. Furthermore, potential consolidation among oil and natural gas exploration and production companies may reduce the number of available customers.

Inflation could adversely impact Parker’s ability to control costs, including operating expenses and capital costs.

Although inflation had been relatively low in recent years, it rose significantly in the second half of 2021 and continued through 2023. In addition, global and industry-wide supply chain disruptions have resulted in shortages in labor, materials and services. Such shortages have resulted in inflationary cost increases for labor, materials and services and could continue to cause costs to increase, as well as a scarcity of certain products and raw materials. To the extent inflation remains elevated, Parker may experience further cost increases for its operations, as well as increased labor costs. Parker cannot predict any future trends in the rate of inflation, and a significant increase in inflation could negatively impact its business, financial condition and results of operations.

Parker’s acquisitions, dispositions, and investments may not result in the realization of savings, the creation of efficiencies, the generation of cash or income, or the reduction of risk, which may have a material adverse effect on its liquidity, consolidated results of operations, and consolidated financial condition.

Parker continually seeks opportunities to maximize efficiency and value through various transactions, including purchases or sales of assets, businesses, investments, or joint ventures. These transactions are intended to result in the realization of savings, the creation of efficiencies, the offering of new products or services, the generation of cash or income, or the reduction of risk. These transactions may also affect Parker’s consolidated results of operations.

These transactions also involve risks, and Parker cannot ensure that:

Parker’s operations are subject to various governmental laws and regulations which require compliance that can be burdensome and expensive.

Parker’s oil and natural gas operations are subject to various federal, state and local governmental regulations that may be changed from time to time in response to economic and political conditions. Matters subject to regulation include discharge permits for drilling operations, drilling bonds, reports concerning operations, the spacing of wells, unitization and pooling of properties and taxation. Failure to comply with these laws and regulations may result in the assessment of sanctions, including administrative, civil or criminal penalties, permit revocations, requirements for additional pollution controls and injunctions limiting or prohibiting some or all of Parker’s operations. Further, these laws and regulations impose strict requirements for water and air pollution control and solid waste management. Significant expenditures may be required to comply with governmental laws and regulations applicable to Parker. Even if federal regulatory burdens temporarily ease, the historic trend of more expansive and stricter environmental legislation and regulations may continue in the long-term, and at the state and local levels.

Regulation of greenhouse gases and climate change could have a negative impact on Parker’s business.

Some scientific studies have suggested that emissions of GHGs may be contributing to warming of the earth’s atmosphere and other climatic changes. Such studies have resulted in increased local, state, regional, national, and international attention and actions relating to issues of climate change and the effect of GHG emissions, particularly emissions from fossil fuels. For example, the Infrastructure Investment and Jobs Act and the IRA include billions of dollars in incentives for the development of renewable energy, clean hydrogen, clean fuels, electric vehicles, investments in advanced biofuels and supporting infrastructure and carbon capture and sequestration. Also, in March 2024, the EPA finalized ambitious rules to reduce harmful air pollutant emissions, including GHGs, from light-, medium-, and heavy-duty vehicles beginning in model year 2027. These incentives and regulations could accelerate the transition of the economy away from the use of fossil fuels towards lower- or zero-carbon emissions alternatives, which could decrease demand for, and in turn the prices of, oil and natural gas and adversely impact Parker’s business. In addition, the IRA imposes the first ever federal fee on the emission of GHGs through a methane emissions charge, which could increase Parker’s operating costs and thereby adversely impact Parker’s business, financial condition and cash flows. In addition, a number of states have either proposed or implemented restrictions on GHG emissions. International accords such as the Paris Agreement may result in additional regulations to control GHG emissions. Other developments focused on restricting GHG emissions include but are not limited to the Kyoto Protocol; the European Union Emission Trading System; the United Kingdom’s Carbon Reduction Commitment; and, in the U.S., the Regional Greenhouse Gas Initiative, the Western Regional Climate Action Initiative, and various state programs. These regulations could also adversely affect market demand or pricing for Parker’s services, by affecting the price of, or reducing the demand for, fossil fuels or providing competitive advantages to competing fuels and energy sources.

Because Parker’s business depends on the level of activity in the oil and natural gas industry, existing or future laws, regulations, treaties, or international agreements related to GHGs and climate change, including incentives to conserve energy or use alternative energy sources, could have a negative impact on Parker’s business if such laws, regulations, treaties, or international agreements reduce the worldwide demand for oil and

56

natural gas or otherwise result in reduced economic activity generally. In addition, such laws, regulations, treaties, or international agreements could result in increased compliance costs or additional operating restrictions, which may have a negative impact on Parker’s business. In addition to potential impacts on Parker’s business directly or indirectly resulting from climate-change legislation or regulations, Parker’s business also could be negatively affected by climate-change related physical changes or changes in weather patterns. An increase in severe weather patterns could result in damages to or loss of Parker’s rigs, impact Parker’s ability to conduct Parker’s operations and/or result in a disruption of Parker’s customers’ operations.

The ultimate impact of GHG emissions and climate change-related agreements, legislation, regulation, and government actions on Parker’s financial performance is highly uncertain because Parker is unable to predict with certainty, for a multitude of individual jurisdictions, the outcome of political decision-making processes, including the actual laws and regulations enacted, the variables and trade-offs that inevitably occur in connection with such processes, and market conditions, including the responses of consumers to such changes.

Restrictions on drilling activities intended to protect certain species of wildlife may adversely affect Parker’s ability to conduct drilling activities in some of the areas where Parker operates.

Oil and natural gas operations in Parker’s operating areas can be adversely affected by seasonal or permanent restrictions on drilling activities designed to protect various wildlife. Seasonal restrictions may limit Parker’s ability to operate in protected areas and can intensify competition for drilling rigs, oilfield equipment, services, supplies and qualified personnel, which may lead to periodic shortages when drilling is allowed. These constraints and the resulting shortages or high costs could delay Parker’s operations and materially increase Parker’s operating and capital costs. Permanent restrictions imposed to protect threatened or endangered species could prohibit drilling in certain areas or require the implementation of expensive mitigation measures. The designation of previously unprotected species in areas where Parker operates as threatened or endangered could cause Parker to incur increased costs arising from species protection measures or could result in limitations on Parker’s drilling activities.

Parker is regularly involved in litigation, some of which may be material.

Parker is regularly involved in litigation, claims, and disputes incidental to its business, which at times may involve claims for significant monetary amounts, some of which would not be covered by insurance. Parker undertakes all reasonable steps to defend itself in such lawsuits. Nevertheless, Parker cannot predict the ultimate outcome of such lawsuits and any resolution which is adverse to it could have a material adverse effect on its financial condition.

Increased regulation of hydraulic fracturing could result in reductions or delays in drilling and completing new oil and natural gas wells, which could adversely impact the demand for rental tools.

Hydraulic fracturing is a process sometimes used in the completion of oil and natural gas wells whereby water, other liquids, sand, and chemicals are injected under pressure into subsurface formations to stimulate natural gas and, oil production. Various governmental entities (within and outside the United States) are in the process of studying, restricting, regulating, or preparing to regulate hydraulic fracturing, directly and indirectly. Many state governments require the disclosure of chemicals used in the fracturing process and, due to concerns raised relating to potential impacts of hydraulic fracturing, including on groundwater quality and seismic activity, legislative and regulatory efforts at the federal level and in some state and local jurisdictions have been initiated to render permitting and compliance requirements more stringent for hydraulic fracturing or prohibit the activity altogether. Parker does not directly engage in hydraulic fracturing activities. However, these and other developments could cause operational delays or increased costs in exploration and production, which could adversely affect the demand for Parker’s rental tools.

57

Parker’s operations are subject to cyber-attacks or other cyber incidents that could have a material adverse effect on its business, consolidated results of operations, and consolidated financial condition.

Parker’s operations are increasingly dependent on information technologies and services, whether such systems are its own or those of its vendors, service providers or customers. Threats to information technology systems associated with cybersecurity risks and cyber incidents or attacks continue to grow, and include, among other things, storms and natural disasters, terrorist attacks, utility outages, theft, viruses, phishing, malware, design defects, human error, and complications encountered as existing systems are maintained, repaired, replaced, or upgraded. The techniques and sophistication used to conduct cyberattacks and compromise information technology infrastructure, as well as the sources and targets of these attacks, change and are often not recognized until such attacks are launched or have been in place for some time. In addition, there has been an increase in state-sponsored cyberattacks, which are often conducted by capable, well-funded groups. The rapid evolution and increased adoption of artificial intelligence technologies amplifies these concerns.

Risks associated with these threats include, among other things:

Any perceived or actual electronic or physical security breach involving the misappropriation, loss, or other unauthorized disclosure of confidential or personally identifiable information, including penetration of Parker’s systems security, whether by it or by a third party, could disrupt its business, damage its reputation and its relationships with its customers or employees, expose Parker to risks of litigation, significant fines and penalties and liability, result in the deterioration of its customers’ and employees’ confidence in Parker, and adversely affect its business, results of operations and financial condition. Although Parker utilizes various procedures and controls to mitigate its exposure to such risk, cybersecurity attacks and other cyber events are evolving and unpredictable. Moreover, Parker has no control over the information technology systems of its customers, suppliers, and others with which its systems may connect and communicate. As a result, the occurrence of a cyber incident could go unnoticed for a period time.

Parker cannot ensure that its cybersecurity insurance will be sufficient to cover any particular losses it may experience as a result of such cyberattacks. Any breach in the security of its information systems or those of its service providers could lead to an interruption in the operation of its systems or loss, disclosure or misappropriation of its business information or other unintended consequences. Such cyber incidents could have a material adverse effect on Parker’s business, financial condition and results of operations.

THE MERGER

Effects of the Merger

At the effective time, Merger Sub, a wholly owned subsidiary of Nabors that was formed for the sole purpose of effecting the merger, will merge with and into Parker. Parker will survive the merger and become a wholly owned subsidiary of Nabors.

In the merger, each share of Parker common stock outstanding immediately prior to the effective time, other than shares owned by Parker and its wholly owned subsidiaries, shares owned by Nabors or Merger Sub and shares for which appraisal rights held by Parker stockholders have been perfected, will be converted at the effective time into the right to receive a number of Nabors common shares based upon the per share merger consideration, and cash (without interest) paid (i) if the Closing Price is lower than the Lower Collar Price; (ii) in lieu of fractional shares and (iii) in connection with the right to receive cash consideration in connection with the disbursement of the Barge Rig Holdback Amount. After the closing, Nabors shareholders will continue to hold their existing Nabors common shares.

Background of the Merger

The management and boards of directors of both Nabors and Parker regularly review the performance, strategy, competitive position, opportunities and prospects of their respective companies, in light of the current macroeconomic environment and developments in the oil and gas sector. As part of this review, Nabors has considered strategic acquisitions on an opportunistic basis from time to time. As described below, Parker pursued a sales process, the outcome of which was the election to proceed in a merger with Nabors.

Nabors and Parker are well known to each other through industry connections. The Nabors board of directors viewed Parker as a strong merger partner because, among other things, the combined company would have a more diversified client mix, additional service offerings, increased geographical diversity, and improved financial flexibility from improved leverage metrics. In addition, the merger would result in cost savings in future years through the elimination of duplicate administrative responsibilities and the opportunity for additional revenue generation opportunities by providing customers with a wider range of services.

In February of 2023, the Finance & Strategic Planning committee of the Parker board of directors (the “F&SP Committee”) authorized the launch of the Parker sales process. Thereafter, Moelis & Company (“Moelis”), financial advisor to Parker, approached Nabors to assess Nabors’ interest in potentially acquiring an oil field services company that provides rental tools, drilling, and well construction services. In March 2023, Nabors executed a non-disclosure agreement with Parker and subsequently received a confidential information memorandum from Moelis. In late March 2023, the Parker board of directors, Parker management and Moelis discussed postponing the formal sales process in light of unfavorable market conditions. In April 2023, Nabors met with Moelis to discuss Parker and the opportunity, and the Parker board of directors and Parker management further discussed the sales process in light of market conditions. In June 2023, Moelis presented an update to the Parker board of directors and Parker management on the sales process, including updates regarding various potential counterparties (including Nabors). During its July 2023 meeting, the Nabors board of directors discussed several potential acquisition candidates, and as one option Nabors’ management provided the board of directors with an overview of Parker and the potential benefits of a transaction. Subsequently, Moelis informed Nabors that Parker’s exploratory sales process had been tabled due to overall poor market conditions, with the potential to restart at a later date.

In September 2023, Moelis and Parker management provided another update to the Parker board of directors regarding the macroeconomic environment and other considerations. In November 2023, Moelis presented an illustrative process timeline for a potential re-launch of the Parker sales process and certain potential bidders to target in such process (including Nabors). Parker also formally re-engaged Moelis as financial advisor for the Parker sales process at the end of 2023.

68

On January 10, 2024, Moelis and Parker management presented an update to the F&SP Committee on the potential re-launch of the Parker sales process and related discussions. In February 2024, Moelis contacted Nabors and conveyed that Parker’s owners were seeking to monetize their stake in Parker, but that Parker was not yet conducting a broad sales process. Nabors indicated it was interested in evaluating Parker on a negotiated basis.

On March 1, 2024, and April 15, 2024, Moelis presented updates to the F&SP Committee and Parker management regarding its discussions with certain potential bidders for Parker (including, but not limited to, Nabors).

On March 8, 2024, Moelis presented an update to the Parker board of directors and Parker management on the Parker sales process and related discussions with potential bidders.

On April 17, 2024, the parties entered into a mutual non-disclosure agreement, which contained customary provisions relating to the sharing of non-public information in connection with the preliminary due diligence and evaluation of a potential business combination, as well as customary standstill restrictions. Shortly thereafter, Moelis shared an updated confidential information memorandum, financial model and quality of earnings workbook with Nabors and discussed arrangements for a management presentation by Parker to Nabors.

On April 26, 2024, Nabors held an initial call with Moelis to discuss the potential transaction including a preliminary timeline and immediate next steps. That same day, Nabors contacted Intrepid Financial Partners (“Intrepid”), seeking to engage them to act as the financial advisor to Nabors with respect to a potential business combination with Parker. Nabors and Intrepid executed an engagement letter on May 9, 2024.

On April 29, 2024, Parker management presented an update to the Parker board of directors on the Parker sales process and related discussions.

On May 6, 2024, Intrepid held initial calls with Moelis to discuss the potential valuation of Parker and the form of consideration in a potential business combination between the two companies. That same day, Moelis populated a virtual dataroom to facilitate the exchange of diligence information related to Parker. Nabors, with assistance from Intrepid, began conducting preliminary due diligence of Parker’s business and financial information in preparation for a forthcoming management presentation to be given by Parker.

Between May 6, 2024, and May 23, 2024, Intrepid and Moelis held several calls to discuss progress on the diligence request information.

On May 23, 2024, Nabors, Intrepid and Moelis attended a management presentation held by Parker at the offices of Moelis, where Parker presented information about Parker’s business, operations, management, product and service portfolio, and financials, as well as a high-level summary regarding potential cost synergies from a business combination between Nabors and Parker.

On May 24, 2024, Moelis and Parker management presented an update to the Parker board of directors on the Parker sales process and related discussions.

On May 28, 2024, Intrepid and Moelis participated in a teleconference regarding the potential terms of a business combination between Nabors and Parker. Intrepid indicated that Nabors was in the process of preparing a letter proposing such a transaction.

On June 4, 2024, following discussions among Nabors’ management team and Intrepid, and believing a potential business combination with Parker would be a strategically beneficial transaction for Nabors and its shareholders, Anthony G. Petrello, Nabors’ Chairperson, President and Chief Executive Officer, sent a letter to Sandy Esslemont, President and Chief Executive Officer of Parker, proposing a merger transaction whereby Nabors would issue 4,600,000 Nabors common shares to shareholders of Parker in order to acquire 100% of the outstanding shares of Parker’s common stock.

69

On June 7, 2024, Moelis, Parker management, and the F&SP Committee discussed an overview of Nabors’ proposal (including the economics thereof), the illustrative benefits of such potential transaction to Parker shareholders (including equity value uplift), and an overview of Nabors and its market metrics. Moelis, Parker management, and the F&SP Committee also discussed a proposed counteroffer to Nabors’ proposal, including an increase of the pro forma equity ownership of Parker stockholders in Nabors to approximately 40%.

Between June 10, 2024, through transaction announcement on October 15, 2024, Intrepid and Moelis held several discussions regarding the transaction.

On June 14, 2024, Moelis, Parker management and the F&SP Committee discussed further a counterproposal from Parker to Nabors that would result in former Parker stockholders receiving 42% of outstanding common shares of the combined company and, on June 17, 2024, Mr. Esslemont sent Mr. Petrello a reply letter with such counterproposal. The letter also requested the addition of two Parker representatives to the board of directors of the combined company.

Nabors’ management team and Intrepid reviewed and discussed Mr. Esslemont’s counterproposal, concluding that the terms did not fairly reflect the relative values of the two companies. On June 19, 2024, Intrepid communicated this position to Moelis and informed them that Nabors was preparing a letter terminating negotiations. Moelis requested that Nabors delay sending such letter to provide Moelis time to review with Parker the status of discussions, and Moelis and Intrepid engaged in further discussion regarding the potential terms of a transaction.

On June 21, 2024, following internal discussions between Nabors management and Intrepid, Nabors authorized Intrepid to submit a verbal counterproposal to Moelis, proposing a merger transaction whereby Nabors would issue an aggregate of 4,800,000 Nabors common shares to stockholders of Parker to acquire 100% of the outstanding shares of Parker common stock.

Between June 22, 2024, and June 28, 2024, Intrepid and Moelis discussed the latest proposal from Nabors. During these discussions, Moelis discussed using the proceeds from the in-process sale of one of Parker’s barge rigs to effectively increase the consideration paid to Parker stockholders, if received prior to closing. In addition, Intrepid indicated that Nabors was considering modifying the structure of its proposal to include a collar.

On June 28, 2024, Moelis, Parker management, and the F&SP Committee discussed a counteroffer proposing a merger transaction whereby Parker stockholders would receive, in the aggregate, (i) 4,800,000 Nabors common shares, plus (ii) the proceeds of the pending barge rig sale by Parker, expected to be $30 million. The proposal also included a termination fee of $25 million payable to Parker if the transaction failed to close and a lock-up whereby 60% of Nabors common shares issued to Parker stockholders could not be traded for the first 90 days following closing of the merger transaction. Following the F&SP Committee meeting, on behalf of Parker, Moelis sent Intrepid a summary term sheet reflecting this counteroffer.

On July 9, 2024, following discussions among Nabors management and members of the Nabors board of directors, including an assessment of Parker’s June 28th proposal, Nabors sent a letter responding to Parker’s June 28th term sheet, which attached a term sheet detailing Nabors’ counterproposal. The term sheet proposed the issuance of 4,800,000 Nabors common shares as consideration in a combination of Nabors and Parker, subject to a collar providing that: (x) if the volume weighted average price for Nabors common shares over the 15 trading days ending five days prior to closing exceeded $88.35 (a share price 25 percent above the $71.16 closing share price of June 28, 2024), the number of Nabors common shares issued would be reduced so the aggregate value of the issued shares equalled $426,960,000; and (y) if the volume weighted average price for Nabors common shares over the 15 trading days ending five days prior to closing was less than $53.37 (a share price 25 percent below the $71.16 closing share price of June 28, 2024), in addition to the shares of Nabors common stock, Nabors would pay a cash amount such that the aggregate value of the merger consideration

70

equalled $256,176,000. The term sheet also provided, among other things, that: (1) any proceeds from the Parker barge rig sales received prior to closing would be paid to Parker stockholders, but all other cash generated after June 30,2024 would remain with Parker and for the ultimate benefit of the combined company; (2) to the extent net debt of Parker at closing exceeded $105 million, consideration would be adjusted downwards; (3) at Closing, Nabors would cover up to $22.5 million of Parker’s transaction expenses; (4) each party would pay the other a $10 million termination fee if it failed to close after satisfaction or waiver of all applicable closing conditions; (5) certain Parker stockholders would execute a lock-up agreement whereby 60% of Nabors common shares it received could not be traded for the first 90 days following closing of the merger transaction, and a post-closing voting agreement where it would agree to vote its Nabors common shares as directed by the Nabors board of directors; and (6) Nabors and Parker would enter into an exclusive negotiating period through September 30, 2024.

On July 10, 2024, Parker management sent a note to the F&SP Committee with its observations regarding Nabors’ July 9, 2024 counterproposal.

On July 11, 2024, Moelis, Parker management, and the F&SP Committee discussed and, on July 14, 2024, Moelis delivered to Nabors and Intrepid a revised draft of the term sheet from Parker that, among other things, eliminated the collar, increased the expense reimbursement to $25 million, provided for a $20 million termination fee payable by Nabors if its shareholders failed to approve the transaction, and added a termination right for Parker if Nabors’ stock underperformed a specified index by more than 15% following the closing.

Between July 14, 2024 and July 30, 2024, Nabors, Parker, Intrepid and Moelis engaged in multiple discussions regarding the terms of the potential business combination.

On July 18, 2024, the F&SP Committee and Parker management held further discussions regarding the terms of the potential business combination. On July 25, 2024, the Parker board of directors and Parker management held further discussions regarding the terms of the potential business combination.

On July 25, 2024, the board of directors of Nabors held an in-person meeting in Bermuda to discuss the potential transaction. In attendance at the meeting were certain senior officers of Nabors and Intrepid and Milbank LLP (“Milbank”), counsel to Nabors. At the board meeting, Intrepid provided an overview and a financial forecast for Parker and the board reviewed the proposed terms of the business combination, as well as potential alternative opportunities. The Nabors board of directors directed Mr. Petrello and Intrepid to proceed with negotiations on definitive documentation that was substantially aligned with the terms presented to the Nabors board of directors.

On July 30, 2024, the parties finalized and executed a non-binding term sheet including key terms for the proposed transaction, which expressly remained subject to the negotiation and entry into definitive documentation, the completion of due diligence, and Nabors’ receipt of representation and warranty insurance. The term sheet provided for the issuance of 4,800,000 Nabors common shares as consideration in a combination of Nabors and Parker, subject to a collar providing that: (x) if the volume weighted average price for Nabors common shares over the 15 trading days ending five days prior to closing exceeded $99.62 (a share price 40 percent above the $71.16 closing share price of June 28, 2024), the number of Nabors common shares issued would be reduced so the aggregate value of the issued shares equalled $478,176,000; and (y) if the volume weighted average price for Nabors common shares over the 15 trading days ending five days prior to closing was less than $42.70 (a share price 40 percent below the $71.16 closing share price of June 28, 2024), in addition to the issuance of Nabors common shares, Nabors would pay a cash amount such that the aggregate value of the merger consideration equalled $204,960,000. The term sheet also provided, among other things, that: (1) to the extent net debt of Parker at closing exceeds $100 million, consideration would be adjusted downwards; (2) at closing, Nabors would cover up to $34 million of Parker’s transaction expenses; and (3) certain Parker stockholders would execute a lock-up agreement whereby 60% of the total Nabors common shares issued in the transaction could not be traded for the first 90 days following closing of the merger transaction, and a

71

post-closing voting agreement where it would agree to vote its common shares of Nabors as directed by the Nabors board of directors. Nabors and Parker also agreed to enter into an exclusive negotiating period through August 30, 2024.

Following execution of the term sheet, Haynes and Boone LLP (“Haynes and Boone”), counsel to Nabors, conducted legal due diligence of Parker.

On August 6, 2024, Moelis began populating Parker’s virtual data room with additional diligence items to facilitate the exchange of requested information.

On August 20, 2024, Haynes and Boone, on behalf of Nabors, distributed an initial draft of the merger agreement to Akin Gump Strauss Hauer & Feld LLP (“Akin”), counsel to Parker.

Remaining open items included the terms of the interim covenant related to Nabors’ ability, between signing and closing, to pay cash upon conversion of Nabors convertible notes and to issue securities convertible into any options, warrants, calls or rights to acquire such interests.

Nabors’ Reasons for the Merger; Recommendation of the Nabors Board of Directors

In approving the merger agreement and recommending that Nabors shareholders approve the issuance of shares of Nabors common shares to Parker stockholders as part of the merger, the Nabors board of directors consulted with members of Nabors’ management, as well as with Nabors’ outside legal and financial advisors. The Nabors board of directors also considered a number of substantive factors, both positive and negative, that the Nabors board of directors viewed as bearing on its decisions, as well as potential benefits and detriments of the merger to Nabors and its shareholders.

The principal factors that the Nabors board of directors viewed as supporting its decisions were:

Strategic Considerations. The Nabors board of directors considered a number of factors pertaining to the strategic rationale for the merger, including the following:

74

Financial Considerations: The Nabors board of directors considered a number of factors pertaining to the financial flexibility and cost savings rationale for the merger, including the following:

Recommendation of Management. The Nabors board of directors took into account the recommendation of the merger by Nabors management.

Consultation with Financial Advisor. The Nabors board of directors considered the financial analysis of Intrepid Financial Partners, which evaluated an overview of the current environment of the oil drilling and energy industry, the transaction structure, the terms of the merger agreement and the potential legal and financial risks pertaining to the merger agreement and corresponding transactions.

Terms of the Merger Agreement. The Nabors board of directors reviewed and considered the terms, and resulting effects, of the merger agreement, including, but not limited to, the following which the Nabors board of directors determined is beneficial to Nabors and its shareholders:

75

See the section titled “The Merger Agreement,” for a detailed discussion of the terms and conditions of the merger agreement.

Voting Agreements. The Nabors board of directors considered that certain Parker stockholders will enter into certain agreements with Nabors, in each case related to the merger and including a voting and support agreements, and a voting and lock-up agreements, which include requirements that certain Parker stockholders vote in favor of the merger to improve certainty of closing the Transactions, refrain from selling Nabors common shares for a certain period of time to prevent rapid sales of Nabors common shares, and enter certain standstill provisions with regards to Nabors.

Post-Merger Corporate Governance. The Nabors board of directors considered that the combined company would be led by Nabors’ existing board of directors and executive management team.

Tax Considerations. The merger is expected to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. Accordingly, Parker stockholders generally are not expected to recognize any gain or loss for U.S. federal income tax purposes upon the exchange of shares of Parker common stock for Nabors common shares pursuant to the merger, except with respect to cash received if the Closing Price is lower than the Lower Collar Price, cash received in connection with the disbursement of certain amounts received in connection with the Barge Rig Holdback Amount and cash received in lieu of fractional Nabors common shares.

Regulatory Approvals. The Nabors board of directors considered the likelihood that the merger will be completed on a timely basis, including the likelihood that the merger will receive all necessary regulatory approvals (and the conditions to which such approvals might be subject) and the likelihood that all conditions to consummation of the merger will be satisfied.

The Nabors board of directors also considered certain potential risks, uncertainties, and other factors weighing negatively against the transactions contemplated by the merger agreement, including, but not limited to, those set forth below:

Business Risks. The Nabors board of directors considered certain risks associated with the merger, including:

Risk of Delay. The Nabors board of directors considered the risk that there is no assurance that all conditions to the parties’ obligations to complete the merger will be satisfied or waived, including customary

76

regulatory clearances, and as a result, it is possible that the merger could be delayed or might not be completed even if approved by each of Nabors’ shareholders and Parker’s stockholders. Additionally, the Nabors board of directors considered the risks and contingencies relating to the announcement and pendency of the merger and the risks and costs to Nabors if the merger does not close timely or does not close at all, including the impact on Nabors’ relationships with clients, employees and other third parties.

Diversion of Management. The Nabors board of directors considered the risk of diverting management focus, employee attention and resources from other strategic opportunities and from operational matters while working to complete the merger and implement merger integration efforts.

Dilution of Nabors Shareholders. The Nabors board of directors considered the fact that the merger would cause dilution to Nabors shareholders and the fact that Parker’s stockholders will own approximately 31% of the issued and outstanding Nabors common shares following the merger, subject to reduction pursuant to the terms of the merger agreement.

Terms and Conditions of the Merger Agreement. The Nabors board of directors considered certain terms and conditions of the merger agreement, including:

77

This discussion of the information and factors considered by the Nabors board of directors in reaching its conclusions and recommendation includes the principal factors considered by the Nabors board of directors but is not intended to be exhaustive and may not include all of the factors considered by the Nabors board of directors. In view of the wide variety of factors considered in connection with its evaluation of the merger and the other transactions contemplated by the merger agreement, and the complexity of these matters, the Nabors board of directors did not find it useful and did not attempt to quantify, rank or assign any relative or specific weights to the various factors that it considered in reaching its determination to approve the merger and the other transactions contemplated by the merger agreement, and to make its recommendation to Nabors shareholders. Rather, the Nabors board of directors viewed its decisions as being based on the totality of the information presented to it and the factors it considered, including its discussions with, and questioning of, members of Nabors management and outside legal and financial advisors. In addition, individual members of the Nabors board of directors may have assigned different weights to different factors.

The Nabors board of directors unanimously approved the merger agreement, the merger and the other transactions contemplated by the merger agreement, and declared the merger agreement, the merger and the other transactions contemplated by the merger agreement (including the issuance of Nabors common shares to Parker stockholders in connection with the merger) to be advisable and fair to and in the best interests of Nabors shareholders.

The Nabors board of directors unanimously recommends that Nabors shareholders vote “FOR” the Nabors share issuance proposal.

Parker’s Reasons for the Merger; Recommendation of the Parker Board of Directors

In reaching its decision to approve and declare advisable the merger agreement and the transactions, the Parker board of directors, as described in “—Background of the Merger,” held a number of meetings, consulted with Parker management and its outside legal advisor, Akin, and Moelis, as financial advisor, and considered the business, assets and liabilities, results of operations, financial performance, strategic direction and prospects of Parker and Nabors. At its meeting held on September 29, 2024 and as subsequently approved by a unanimous written consent on October 13, 2024, after due consideration and consultation with Parker management and outside legal and financial advisors, the Parker board of directors unanimously approved and declared advisable the merger agreement and the transactions and recommended that Parker stockholders vote in favor of the adoption of the merger agreement.

In making its determination, approval, and in recommending that the Parker stockholders vote in favor of the adoption of the merger agreement, the Parker board of directors considered a number of factors (not necessarily in order of relative importance) that the Parker board of directors viewed as being generally positive or favorable in coming to its determination, approval, and related recommendation, including the following:

78

79

The Parker board of directors also considered a number of uncertainties, risks and factors it deemed generally negative or unfavorable in making its determination, approval and related recommendation, including the following (not necessarily in order of relative importance):

80

The Parker board of directors considered all of these factors as a whole, as well as others, and, on balance, concluded that it supported a favorable determination to approve the merger agreement and to make its recommendation to Parker stockholders.

In addition, the Parker board of directors was aware of and considered the interests of its directors and executive officers that are different from, or in addition to, the interests of Parker stockholders generally, including the treatment of equity awards held by such directors and executive officers in the merger described in “—Interests of Parker Directors and Executive Officers in the Merger” and the obligation of the combined company to indemnify Parker directors and officers against certain claims and liabilities.

The foregoing discussion of the information and factors that the Parker board of directors considered is not intended to be exhaustive, but rather is meant to include the material factors that the Parker board of directors considered. The Parker board of directors collectively reached the conclusion to approve the merger agreement and the transactions in light of the various factors described above and other factors that the members of the Parker board of directors believed were appropriate. In view of the complexity and wide variety of factors, both positive and negative, that the Parker board of directors considered in connection with its evaluation of the merger, the Parker board of directors did not find it practical, and did not attempt, to quantify, rank or otherwise assign relative or specific weights or values to any of the factors it considered in reaching its decision and did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular

81

factor, was favorable or unfavorable to the ultimate determination of the Parker board of directors. Moreover, each member of the Parker board of directors applied his or her own personal business judgment to the process and may have given different weight to different factors. The Parker board of directors based its recommendation on the totality of the information presented, including thorough discussions with, and questioning of, Parker management and Parker’s outside legal advisor. In considering the factors discussed above, individual directors may have given different weights to different factors.

The foregoing description of Parker’s consideration of the factors supporting the merger is forward-looking in nature. This information should be read in light of the factors discussed in “Special Note Regarding Forward-Looking Statements.”

Certain Unaudited Prospective Financial Information of Nabors and Parker

Neither Nabors nor Parker as a matter of course makes public long-term projections as to its future earnings or other results because of, among other reasons, the uncertainty of the underlying assumptions and estimates. However, Nabors and Parker are including the following summary of certain internal, unaudited prospective financial information from Nabors’ management’s projections for Nabors and Parker (described below under “—Unaudited Prospective Financial Information Prepared by Nabors”) solely because that information was made available to the Nabors board of directors. Similarly, the following summary of the unaudited prospective financial information from Parker’s management’s projections for Parker (described below under “—Unaudited Prospective Financial Information Prepared by Parker”) are included in this joint proxy statement/prospectus solely because that information was made available to the Parker board of directors. The inclusion of the below information should not be regarded as an indication that Nabors, Parker or any other recipient of this information considered—or now considers—it to be necessarily predictive of actual future results, or that it should be construed as financial guidance, and such summary projections set forth below should not be relied on as such.

The unaudited prospective financial information prepared by the respective managements of Nabors and Parker was, in general, prepared solely for Nabors’ and Parker’s internal use and is subjective in many respects.

The prospective financial information for Nabors was based solely upon information available to Nabors’ management and the prospective financial information for Parker was based solely upon information available to Parker’s management, in each case at the time of preparation. As a result, there can be no assurance that the prospective results will be realized or that actual results will not be significantly higher or lower than estimated. Since the unaudited prospective financial information covers multiple years, that information by its nature becomes less predictive with each successive year.

While presented in this joint proxy statement/prospectus with numeric specificity, the information set forth in the summary of Nabors’ and Parker’s prospective financial information contained in this joint proxy statement/prospectus was based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of Nabors’ and Parker’s management. Both Nabors and Parker believe the assumptions in the prospective financial information were reasonable at the time the financial information was prepared, given the information both Nabors and Parker had at the time. However, important factors that may affect actual results and cause the results reflected in Nabors’ and Parker’s prospective financial information not to be achieved include, but are not limited to, risks and uncertainties relating to their respective businesses, industry performance, the regulatory environment, general business and economic conditions and other matters described under the section of this joint proxy statement/prospectus titled “Risk Factors.” See also “Special Note Regarding Forward-Looking Statements” and “Where You Can Find More Information.” The prospective financial information also reflects assumptions as to certain business decisions that are subject to change.

The unaudited prospective financial information for Nabors and Parker includes Adjusted Gross Margin and Adjusted EBITDA, non-GAAP financial measures. Please see the tables below for a description of how

82

Nabors and Parker define Adjusted EBITDA and Adjusted Gross Margin. Nabors and Parker believe that Adjusted EBITDA and Adjusted Gross Margin provide information useful in assessing operating and financial performance across periods. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in accordance with GAAP, and non-GAAP financial measures used by Nabors and Parker may not be comparable to similarly titled measures used by other companies.

The unaudited prospective financial information for Nabors and Parker does not take into account all the possible financial and other effects on Nabors or Parker, respectively, of the merger, the effect on Nabors or Parker, respectively of any business or strategic decision or action that has been or will be taken as a result of the merger agreement having been executed, or the effect of any business or strategic decisions or actions which would likely have been taken if the merger agreement had not been executed, but which were instead altered, accelerated, postponed or not taken in anticipation of the merger. Further, the unaudited prospective financial information for Nabors and Parker does not take into account the effect on Nabors or Parker, respectively, of any possible failure of the merger to occur. The inclusion of the unaudited prospective financial information for Nabors and Parker herein should not be deemed an admission or representation by Nabors, Parker, as applicable, or their respective affiliates, officers, directors, advisors or other representatives that it is viewed as material information of Nabors or Parker, particularly in light of the inherent risks and uncertainties associated with such forecasts.

Nabors and Parker can give no assurance that, had Nabors’ prospective financial information or Parker’s prospective financial information, as applicable, been prepared either as of the date of the merger agreement or as of the date of this joint proxy statement/prospectus, similar estimates and assumptions would be used. Except as required by applicable securities laws, Nabors and Parker do not intend to make publicly available any update or other revision to the prospective financial information to reflect circumstances existing since their preparation or to reflect the occurrence of unanticipated events, even in the event that any or all of the underlying assumptions are shown not to be appropriate, or to reflect changes in general economic or industry conditions.
