RECENT DEVELOPMENTS CORPORATE REORGANIZATION Effective June 24, 2002, Nabors became the successor to Nabors Delaware following a corporate reorganization, which effectively changed the jurisdiction of incorporation of Nabors from Delaware to Bermuda. The reorganization was accomplished through a merger of an indirect, newly formed Delaware subsidiary of Nabors with and into Nabors Delaware. Nabors Delaware was the surviving company in the merger. As a result of the merger, Nabors Delaware became a wholly-owned, indirect subsidiary of Nabors. Upon consummation of the merger, all outstanding shares of Nabors Delaware common stock automatically converted into the right to receive Nabors common shares, with the result that the shareholders of Nabors Delaware on the date of the merger became the shareholders of Nabors. Nabors and its subsidiaries continue to conduct the businesses previously conducted by Nabors Delaware and its subsidiaries. The reorganization has been accounted for as a reorganization of entities under common control and, accordingly, it did not result in any changes to the consolidated amounts of assets, liabilities and stockholders' equity. The Board of Nabors Delaware approved the expatriation transaction because international activities are an important part of Nabors' current business and they believe that international operations will continue to grow in the future. Expansion of Nabors' international business is an important part of its current business strategy and significant growth opportunities exist in the international marketplace. Nabors believes that reorganizing as a Bermuda company will allow Nabors to implement its business strategy more effectively. In addition, Nabors believes that the reorganization should increase its access to international capital markets and acquisition opportunities, increase its attractiveness to non-U.S. investors, improve global cash management, improve its global tax position and result in a more favorable corporate structure for expansion of its current business. 3 Several members of the United States Congress have introduced legislation that, if enacted, would have the effect of eliminating the tax benefits of the reorganization. In particular, on June 18, 2002, the Senate Finance Committee approved legislation introduced by Senator Charles Grassley, the Ranking Minority Member of the Senate Finance Committee, along with Senator Max Baucus, the Chairman of the Senate Finance Committee, (S. 2119) that, for United States federal tax purposes, would treat a foreign corporation, such as Nabors, that undertakes a corporate expatriation transaction, such as the reorganization, as a domestic corporation and, thus, such foreign corporation would be subject to United States federal income tax. S. 2119 is proposed to be effective for corporate expatriation transactions completed after March 20, 2002. In addition, on July 11, 2002, Representative Bill Thomas, Chairman of the House Committee on Ways and Means, introduced legislation (H.R. 5095) that is substantially similar to S. 2119 with respect to its treatment of corporations that undertake a corporate expatriation transaction such as the reorganization, except that (i) it is proposed to apply to transactions completed after March 20, 2002 and before March 21, 2005 and (ii) it would not permit shareholders to qualify for tax-free treatment with respect to a corporate expatriation transaction such as the reorganization. If any of the proposed legislation, including S. 2119 or H.R. 5095, were enacted with their proposed effective dates, the tax savings would not be realized from the reorganization. In addition, there has been increased negative publicity and criticism of corporate expatriation transactions from public pension funds and other investors since the time Nabors completed its reorganization. In light of such events and if and when any such legislation is enacted, Nabors will consider the effects of such legislation and will evaluate all strategic alternatives that may be necessary or prudent in response to such legislation. ACQUISITION

4

TABLE OF RYAN On August 12, 2002, Nabors entered into an arrangement agreement to acquire Ryan Energy Technologies Inc., a corporation incorporated under the laws of Alberta, Canada (which we refer to as Ryan in this prospectus). Nabors' acquisition of Ryan was completed on October 9, 2002, and became effective pursuant to a plan of arrangement approved by the securityholders of Ryan and the Court of Queen's Bench of Alberta. Under the terms of the arrangement each holder of Ryan common shares could elect to receive for each Ryan common share either cash in the amount of Cdn. $1.85 or 0.0362 of an exchangeable share of Nabors Exchangeco (Canada) Inc., a Canadian corporation and an indirect wholly-owned subsidiary of Nabors (which we refer to as Exchangeco in this prospectus). Each registered shareholder electing to receive Exchangeco shares received only a whole number of exchangeable shares, and was paid cash in lieu of any fractional shares. Each exchangeable share has economic and voting rights effectively equivalent to one Nabors common share and is exchangeable at any time for one Nabors common share. As a result of the arrangement, all options to acquire Ryan common shares not previously exercised or surrendered for termination were terminated and each holder of such options was paid in cash, in respect of each such option, the greater of: (i) the positive difference, if any, between Cdn. $1.85 and the exercise price of such option for each Ryan common share issuable on exercise of such option, and (ii) Cdn. $0.10 per common share issuable on exercise of such option, subject to required withholdings. Pursuant to the arrangement, Exchangeco acquired all of the issued and outstanding common shares of Ryan in exchange for approximately Cdn. $22.6 million (U.S. $14.2 million) in cash and 380,264 exchangeable shares of Exchangeco, of which 219,493 exchangeable shares were immediately exchanged for common shares of Nabors in accordance with the instructions of the holders of those shares.

transfer of that ownership interest will be effected only through, records maintained by the depositary or its nominee for the global notes. Ownership of beneficial interests in global notes by persons that hold the beneficial interests through participants will be shown on, and the transfer of that ownership interest within such participant will be effected only through, records maintained by the participant.
So long as the depositary for a global note in registered form, or its nominee, is the registered owner of the global note, the depositary or the nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global note for all purposes under the applicable indenture governing the debt securities. Except as described below, owners of beneficial interests in the global notes will not be entitled to have debt securities of the series represented by the global notes registered in their names, will not receive or be entitled to receive physical delivery of debt securities of the series in definitive form and will not be considered the owners or holders thereof under the applicable indenture.
Payment of principal of, premium, if any, and interest, if any, interest on debt securities registered in the name of or held by a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner or the holder of the global note representing the debt securities. The applicable Nabors issuerDelaware will not (nor will the trustee, any paying agent or the security registrar for the debt securities) have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global note for the debt securities or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.
We expect that the depositary for debt securities of a series, upon receipt of any payment of principal of, premium or interest in respect of a permanent global note, will credit immediately participants'participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global note as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in the global note held through the participants will be governed by customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in "street“street name," and will be the responsibility of the participants.
A global note may not be transferred except as a whole by the depositary for the global note to a nominee of the depositary, or by a nominee of the depositary to the depositary or to another nominee of the 11 depositary or by the depositary or any nominee to a successor of the depositary or a nominee of the successor. If a depositary for debt securities of a series is at any time unwilling or unable to continue as a depositary and a successor depositary is not appointed by us within 90 days, weNabors Delaware will issue debt securities in definitive registered form in exchange for the global note or notes representing the debt securities. In addition, the applicable Nabors issuer may at any time and in its sole discretion determine not to have any debt securities in registered form represented by one or more global notes and, in that event, such Nabors issuer will issue debt securities in definitive form in exchange for the global note or notes representing

Accordingly, the board of directors, and not the shareholders, has the authority to determine the number of directors and could delay any shareholder from obtaining majority representation on the board of directors by enlarging the board of directors and filling the new vacancies with its own nominees.
The bye-lawsBye-laws of Nabors provide that, at any annual general meeting, only such business shall be conducted as shall have been brought before the meeting by or at the direction of the board of directors, by any shareholder who complies with certain procedures set forth in the bye-lawsBye-laws or by any shareholder pursuant to the valid exercise of the power granted under the Companies Act.
For business to be properly brought before an annual general meeting by a shareholder in accordance with the terms of the bye-lawsBye-laws the shareholder must have given timely notice thereof in proper written form to the Secretary of Nabors and satisfied all requirements under applicable rules promulgated by the 21 SEC.Nabors. To be timely for consideration at the annual general meeting, a shareholder'sshareholder’s notice must be received by the Secretary at Nabors'Nabors’ principal executive offices and its registered office in Bermuda not less than 60 days nor more than 90 days prior to the anniversary date of the immediately preceding annual general meeting, or, in the event that the annual general meeting is called for a date that is not within 30 days before or after such anniversary date, not later than the 10th day following the day on which such notice of the date of the annual general meeting was mailed or public disclosure of the date of the annual general meeting was made, whichever occurs first.

Subject to the terms of any other class of shares in issue, any action required or permitted to be taken by the holders of Nabors'Nabors’ common shares must be taken at a duly called annual or special general meeting of shareholders unless taken by written consent of all holders of common shares. Under the bye-laws,Bye-laws, special general meetings may be called at any time by the board of directors or when requisitioned by shareholders or otherwise required pursuant to the provisions of the Companies Act. The Companies Act currently permits shareholders holding 10% of the paid up capital shares of a company entitled to vote at general meeting to requisition a special general meeting.
The board of directors of Nabors is authorized, without obtaining any vote or consent of the holders of any class or series of shares unless expressly provided by the terms of issue of a class or series, to from time to time issue any authorized and unissued shares on such terms and conditions as it may determine. For example, the board of directors could authorize the issuance of common or preferred shares with terms and conditions that could discourage a takeover or other transaction that holders of some or a majority of the Nabors common shares might believe to be in their best interests or in which holders might receive a premium for their shares over the then market price of the shares.
PREFERRED SHARES

in each case, as set forth in the resolutions authorizing the class or series of preferred shares.
The only series of preferred shares issued and outstanding as of December 31, 2020 was the Series A Preferred Shares, which is described below under “— Series A Preferred Shares.”

23


SERIES A PREFERRED SHARES
Ranking
Our Series A Preferred Shares rank with respect to dividend rights and rights upon our liquidation, winding up or dissolution, senior to our common shares and any class or series of our preferred shares that rank junior to the Series A Preferred Shares and may rank junior, equal or senior to any series of preferred shares we may issue in the future.
Dividends
Holders of our Series A Preferred Shares are entitled to receive, when, as and if declared by our board of directors out of funds lawfully available for payment, cumulative dividends at the rate per annum of 6.00% per share on the initial liquidation preference of $50 per Series A Preferred Share (equivalent to $3.00 per annum per share), payable in cash, common shares or a combination thereof, at our election and subject to the share cap (as defined below). Dividends on the Series A Preferred Shares are payable quarterly on February 1, May 1, August 1 and November 1 of each year, ending on May 1, 2021, at such annual rate, and shall accumulate from the most recent date as to which dividends shall have been paid or, if no dividends have been paid, from the first date of original issuance for the Series A Preferred Shares, whether or not in any dividend period or periods there have been funds lawfully available for the payment of such dividends.
No dividend must be declared or paid upon, or any sum set apart for the payment of dividends upon, any issued and outstanding share of the Series A Preferred Shares with respect to any dividend period unless all dividends for all preceding dividend periods have been declared and paid or declared and a sufficient sum has been set apart for the payment of such dividends, upon all issued and outstanding Series A Preferred Shares.
If we pay any dividend or portion thereof in common shares, such shares shall be valued for such purpose at 97% of the average VWAP per common share for the five trading days of the relevant dividend reference period. The aggregate number of our common shares delivered in respect of dividends per Series A Preferred Share shall in no event exceed the maximum conversion rate. To the extent that we elect to pay any accumulated and unpaid dividends, in whole or in part, by delivering our common shares, and the share cap results in us delivering fewer common shares than we would have been required to deliver in the absence of the share cap, we will, if we are legally able to do so, pay cash in respect of the deficit amount resulting from application of the share cap.
Liquidation
Upon our voluntary or involuntary liquidation, dissolution or winding-up, holders of the Series A Preferred Shares and any parity shares are entitled to receive out of our assets available for distribution to shareholders, after satisfaction of liabilities to creditors, if any, and the liquidation preference of any of our share capital ranking senior to the Series A Preferred Shares with respect to distribution of assets upon our liquidation, dissolution or winding up, if any, but before any distribution of assets is made to holders of our common shares or any of our other shares ranking junior as to such a distribution to the Series A Preferred Shares, a liquidating distribution in the amount of $50 per Series A Preferred Shares plus an amount equal to any accumulated and unpaid dividends, whether or not declared. If in any such distribution, our assets or proceeds thereof are not sufficient to pay the liquidating distribution, distributions will be made pro rata as to the Series A Preferred Shares and any parity shares but only to the extent we have assets available after satisfaction of all liabilities to creditors, if any, and the full liquidation preference of any of our share capital ranking senior to the Series A Preferred Shares with respect to distribution of assets upon our liquidation, dissolution or winding-up, if any. Holders of the Series A Preferred Shares will not be entitled to any other amounts from us after they have received their full liquidation preference.
In any such distribution, if our assets are not sufficient to pay the liquidation preferences in full to all holders of the Series A Preferred Shares and all holders of any parity shares, the amounts paid to the holders of Series A Preferred Shares and to the holders of any parity shares will be paid pro rata in accordance with the respective aggregate liquidation preferences of those holders. In any such distribution, the liquidation distribution of any holder of preferred shares means the amount payable to such holder in such distribution,

24


including any accumulated and unpaid dividends, whether or not declared. If the liquidation preference has been paid in full to all holders of the Series A Preferred Shares and any holders of parity shares and shares ranking senior to the Series A Preferred Shares with respect to the distribution of assets upon our liquidation, dissolution or winding-up, the holders of our other shares shall be entitled to receive all of our remaining assets according to their respective rights and preferences.
Voting Rights
Except as provided below, the holders of the Series A Preferred Shares will have no voting rights.
Preferred Shares Directors
Whenever dividends on any Series A Preferred Shares shall have not been declared and paid for the equivalent of six or more dividend periods, whether or not for consecutive dividend periods (a “nonpayment event”), the holders of the Series A Preferred Shares, voting together as a single class with holders of any and all other series of voting preferred shares (as defined below) then issued and outstanding, will be entitled to vote for the election of a total of two additional directors to our board of directors (the “preferred shares directors”); provided that the election of any such directors shall not cause us to violate the corporate governance requirement of any exchange on which our securities may be listed or quoted that listed or quoted companies must have a majority of independent directors. The number of preferred shares directors on our board of directors shall never be more than two at any one time. In that event, the new directors shall be elected initially at a special general meeting called at the request of the holders of record of at least 20% of the aggregate voting power of the Series A Preferred Shares or of any other series of voting preferred shares (unless such request is received less than 90 days before the date fixed for the next annual or special meeting of our shareholders, in which event such election shall be held at such next annual or special general meeting of shareholders), and, thereafter, at each subsequent annual general meeting of our shareholders, so long as the rights relative to a nonpayment event remain in effect. Such request to call a special general meeting for the initial election of the preferred shares directors after a nonpayment event shall be made by written notice signed by the requisite holders of the Series A Preferred Shares or any other series of voting preferred shares and delivered to our secretary in any manner as may be permitted by our Bye-laws or by any other manner as permitted by Bermuda law.
“Voting preferred shares” means any other class or series of our preferred shares ranking equally with the Series A Preferred Shares as to dividends and the distribution of assets upon our liquidation, dissolution or winding-up and upon which like voting rights have been conferred and are exercisable. Whether a plurality, majority or other portion of the Series A Preferred Shares and any other voting preferred shares have been voted in favor of any matter shall be determined by reference to the aggregate liquidation preference of the Series A Preferred Shares and voting preferred shares voted.
If and when all accumulated dividends have been paid in full (or declared and a sum sufficient for such payment shall have been set aside), the holders of the Series A Preferred Shares shall be divested of the foregoing voting rights (subject to revesting in the event of each subsequent nonpayment event) and, if such voting rights for all other holders of voting preferred shares have terminated, the term of office of each preferred shares director so elected shall terminate and the number of directors on our board of directors shall automatically decrease by two.
Any preferred shares director may be removed at any time without cause by the holders of record of a majority of the aggregate liquidation preference of Series A Preferred Shares and any other voting preferred shares then issued and outstanding (voting together as a single class) when they have the voting rights described above. So long as a nonpayment event shall continue, any vacancy in the office of a preferred shares director (other than prior to the initial election after a nonpayment event) may be filled by the written consent of the preferred shares director remaining in office, or if none remains in office, by a vote of the holders of record of a majority of the issued and outstanding series A preferred shares and any other voting preferred shares then issued and outstanding (voting together as a single class by reference to the aggregate liquidation preference of all preferred shares so entitled to vote) when they have the voting rights described above. Any vote of preferred shareholders to remove, or to fill a vacancy in the office of, a preferred shares director may be taken only at a special general meeting of such preferred shareholders, called as provided above for an initial election of preferred shares directors after a nonpayment event (unless such request is

25


received less than 90 days before the date fixed for the next annual or special general meeting of our shareholders, in which event such election shall be held at such next annual or special general meeting of shareholders). The preferred shares directors shall each be entitled to one vote per director on any matter that shall come before the board of directors for a vote. Each preferred shares director elected at any special general meeting of shareholders or by written consent of the other preferred shares director shall hold office until the next annual meeting of our shareholders if such office shall not have previously terminated as above provided.
General
The Companies Act provides that in certain circumstances, non-voting shares such as the Series A Preferred Shares have the right to vote (for example without limitation, converting a limited liability company to unlimited liability company, discontinuance of a company from Bermuda, an amalgamation or merger of a Bermuda company, or conversion of preferred shares into redeemable preferred shares).
Conversion Rights
Mandatory Conversion
Each of our Series A Preferred Shares, unless previously converted, will automatically convert on the second business day immediately following the last trading day of the twenty consecutive trading day period beginning on, and including the 21st scheduled trading day immediately preceding May 1, 2021 (the “mandatory conversion date”) into a number of common shares equal to the conversion rate described below. In addition to the common shares issuable upon conversion of each of our Series A Preferred Shares on the mandatory conversion date, holders will have the right to receive an amount equal to all accumulated and unpaid dividends on the Series A Preferred Shares, whether or not declared prior to that date, for the then-current dividend period ending on May 1, 2021 and all prior dividend periods, so long as we are lawfully permitted to pay such dividends at such time. To the extent that we elect to pay such accumulated and unpaid dividends, in whole or in part, by delivering our common shares, and the share cap results in us delivering fewer common shares than we would have been required to deliver in the absence of the share cap, we will, if we are legally able to do so, pay cash in respect of the deficit amount resulting from application of the share cap.
The conversion rate, which is the number of common shares issuable upon conversion of each Series A Preferred Share on the applicable conversion date (excluding common shares, if any, issued in respect of accumulated and unpaid dividends), will, subject to customary conversion rate adjustments, be as follows:

if the applicable market value (as defined below) of our common shares is greater than $9.30 (the “threshold appreciation price”) then the conversion rate will be 5.3763 of our common shares per Series A Preferred Share (the “minimum conversion rate”), which is approximately equal to $50, divided by the threshold appreciation price;

if the applicable market value of our common shares is less than or equal to the threshold appreciation price but greater than or equal to $7.75 (the “initial price”) then the conversion rate will be equal to $50, divided by the applicable market value of our common shares; or

if the applicable market value of our common shares is less than the initial price, then the conversion rate will be 6.4516 of our common shares per series A preferred share (the “maximum conversion rate”), which is approximately equal to $50, divided by the initial price.
We refer to the minimum conversion rate and the maximum conversion rate collectively as the “fixed conversion rates.”
“Volume-weighted average price” or “VWAP” per common share (or any other security for which a VWAP must be determined) on any trading day means such price as displayed under the heading “Bloomberg VWAP” on Bloomberg (or any successor service) page NBR <Equity> AQR (or its equivalent successor if such page is not available) or, in the case of such other security, the per share volume-weighted average price as displayed on the Bloomberg page with respect to such security, in each case in respect of the period from the scheduled open to 4:00 p.m., New York City time, on such trading day; or, if such price is not

26


available, the volume-weighted average price means the market value per common share (or such other security) on such trading day as determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained by us for this purpose. The “average VWAP” means, for any period, the average of the VWAPs for each trading day in such period.
The “applicable market value” of our common shares is the average VWAP per common share over the final averaging period.
Conversion at the Option of the Holder
Other than during the fundamental change conversion period (as defined below), holders of the Series A Preferred Shares have the right to convert the Series A Preferred Shares, in whole or in part, at any time prior to May 1, 2021, into our common shares at the minimum conversion rate of 5.3763 of our common shares per Series A Preferred Share, subject to ordinary conversion rate adjustments. In addition to the number of common shares issuable at the minimum conversion rate upon conversion of each Series A Preferred Share at the option of the holder on any date on which a holder converts Series A Preferred Shares at such holder’s option (the “early conversion date”), we will pay an amount equal to all accumulated and unpaid dividends on such converted Series A Preferred Shares, whether or not declared prior to that date, for all dividend periods ending on or prior to the dividend payment date immediately preceding the early conversion date, subject to the immediately succeeding paragraph and the share cap and so long as we are then lawfully permitted to pay such dividends. To the extent that we elect to pay such accumulated and unpaid dividends, in whole or in part, by delivering our common shares, and the share cap results in us delivering fewer common shares than we would have been required to deliver in the absence of the share cap, we will have no obligation to pay any cash or deliver any additional common shares in respect of the deficit amount resulting from application of the share cap. Holders who exercise the optional conversion right will not be entitled to receive dividends for the then-current dividend period.
Notwithstanding the foregoing, if the early conversion date for any optional conversion occurs during the period from 5:00 p.m., New York City time, on a regular record date for any declared dividend to 9:00 a.m., New York City time, on the immediately following dividend payment date, then:

we will pay such dividend on the dividend payment date to the holder of record of the converted Series A Preferred Shares on such regular record date;

Series A Preferred Shares surrendered for conversion during such period must be accompanied by cash in an amount equal to the amount of such dividend for the then-current dividend period with respect to the share(s) so converted; and

the consideration that we deliver to the converting holder on the early conversion date will not include any consideration in respect of such dividend.
Conversion Upon Fundamental Change
If a fundamental change (as defined below) occurs prior to the mandatory conversion date, we will provide for the conversion of Series A Preferred Shares by paying or delivering, as the case may be, to holders who convert their Series A Preferred Shares at any time during the period (the “fundamental change conversion period”) beginning on, and including, the effective date of such fundamental change (the “effective date”) and ending on, but excluding, the earlier of (i) the mandatory conversion date and (ii) the date that is 20 calendar days after the effective date:

a number of our common shares or units of exchange property, as described under “—Recapitalizations, Reclassifications and Changes of Our Common Shares” ​(if the fundamental change also constitutes a reorganization event), per Series A Preferred Share equal to the conversion rate (the “fundamental change conversion rate”) determined using the table below; and

at our election and subject to the share cap, our common shares (or, if applicable, units of exchange property), cash or a combination thereof in an amount equal to any accumulated and unpaid dividends to the applicable conversion date, whether or not declared, on their Series A Preferred Shares, to the extent that we have lawfully available funds to pay such dividends; provided, however, that if the conversion date for such conversion occurs during the period from 5:00 p.m., New York City time, on

27


a regular record date for any declared dividend to 9:00 a.m., New York City time, on the immediately following dividend payment date, then we will pay such dividend on the dividend payment date to the holder of record of the converted Series A Preferred Shares on such regular record date and the consideration that we deliver to the converting holder will not include any consideration in respect of such dividend.
To the extent that we elect to pay the accumulated and unpaid dividends described in the immediately preceding bullet, in whole or in part, by delivering our common shares, and the share cap results in us delivering fewer common shares than we would have been required to deliver in the absence of the share cap, we will, if we are legally able to do so, pay cash in respect of the deficit amount resulting from application of the share cap.
We will notify holders of the anticipated effective date of a fundamental change at least 20 calendar days prior to such anticipated effective date or, if such prior notice is not practicable, notify holders of the effective date of a fundamental change no later than such effective date (the “fundamental change company notice”). If we notify holders of a fundamental change later than the 20th calendar day prior to the effective date of a fundamental change, the fundamental change conversion period will be extended by a number of days equal to the number of days from, and including, the 20th calendar day prior to the effective date of the fundamental change to, but excluding, the date of the notice; provided that the fundamental change conversion period will not be extended beyond the mandatory conversion date. The fundamental change company notice will state, among other things, whether we have elected to pay all or any portion of accumulated and unpaid dividends in common shares or units of reference property, as the case may be, and, if so, the portion thereof (as a percentage) that will be paid in common shares or units of exchange property.
Notwithstanding the foregoing, if we deliver the fundamental change company notice after the date that is six scheduled trading days prior to the effective date of the fundamental change, we will be required to pay all accumulated and unpaid dividends in cash.
A “fundamental change” will be deemed to have occurred (1) upon the occurrence of a change in control (as defined below) or (2) when the common shares (or other common shares underlying the series A preferred shares) cease to be listed or quoted on the New York Stock Exchange, NYSE MKT LLC, The NASDAQ Global Select Market, The NASDAQ Global Market or The NASDAQ Capital Market (or any of their respective successors).
A “change in control” shall be deemed to have occurred at such time as any of the following events shall occur:
1.   any person or group, other than Nabors, Nabors’ subsidiaries or any employee benefits plan of Nabors or its subsidiaries, files a Schedule 13D or Schedule TO (or any successor schedule, form or report) pursuant to the Exchange Act, disclosing that such person or group has become the beneficial owner of shares with a majority of total voting power of the common shares; unless such beneficial ownership (a) arises solely as a result of a revocable proxy delivered in response to a proxy or consent solicitation made pursuant to the applicable rules and regulations under the Exchange Act, and (b) is not also then reportable on Schedule 13D (or any successor schedule) under the Exchange Act;
2.   Nabors consolidates with, amalgamates or merges with or into another person (other than one of its subsidiaries), or sells, conveys, transfers or leases all or substantially all of its properties and assets to any person (other than one of its subsidiaries) or any person (other than one of its subsidiaries) consolidates with or merges with or into Nabors, and (except in the case of any such sale, conveyance, transfer or lease) the issued and outstanding common shares are reclassified into, converted for or converted into the right to receive any other property or security; or
3.   the first day on which the majority of the members of the board of directors of Nabors cease to be Continuing Directors.

28


For purposes of defining a change in control:
(w)   “Continuing Director” means, as of any date of determination, any member of the board of directors of Nabors who: (1) was a member of such board of directors (a) on the date of the original issuance of the series A preferred shares or (b) for at least two consecutive years; or (2) was nominated for election, elected or appointed to such board of directors with the approval of a majority of the Continuing Directors who were members of such board of directors at the time of such nomination, election or appointment (either by a specific vote or by approval of the Nabors’ proxy statement in which such member was named as a nominee for election as a director, without objection to such nomination);
(x)   the term “person” and the term “group” have the meanings given by Section 13(d) and 14(d) of the Exchange Act or any successor provisions;
(y)   the term “group” includes any group acting for the purpose of acquiring, holding or disposing of securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act or any successor provision; and
(z)   the term “beneficial owner” is determined in accordance with Rules 13d-3 and 13d-5 under the Exchange Act or any successor provisions, except that a person will be deemed to have beneficial ownership of all shares that person has the right to acquire irrespective of whether that right is exercisable immediately or only after the passage of time.
Notwithstanding the foregoing, it will not constitute a change in control if at least 90% of the consideration for the common shares (excluding cash payments for fractional shares and cash payments made in respect of dissenters’ appraisal rights) in the transaction or transactions constituting the change in control consists of common stock or common shares traded on a United States national securities exchange or approved for quotation on the New York Stock Exchange, NYSE MKT LLC, The NASDAQ Global Select Market, The NASDAQ Global Market or The NASDAQ Capital Market (or any of their respective successors), or which will be so traded or quoted when exchanged in connection with the change in control transaction, and as a result of such transaction or transactions the series A preferred shares become convertible or exchangeable solely into such common stock or common shares.
If any transaction in which our common shares are replaced by the securities of another entity occurs, following completion of the related fundamental change conversion period, references to us in the definition of “change in control” above shall instead be references to such other entity.
The “fundamental change conversion rate” will be determined by reference to the table above, based on the effective date and the “share price” in the fundamental change, which will be:

in the case of a fundamental change described in clause (ii) of the definition of “change of control” above in which all holders of our common shares receive only cash in the change of control, the cash amount paid per common share; and

otherwise, the average VWAP per common share over the 10 trading day period ending on, and including, the trading day immediately preceding the effective date of the fundamental change.
Conversion at Our Option Upon Tax Event
If, as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of any taxing jurisdiction, or any change in official position regarding the application or interpretation of such laws, regulations or rulings (including a holding by a court of competent jurisdiction), which change, amendment, application or interpretation is announced and becomes effective on or after the date of this prospectus supplement (any such change, a “tax event”).

Certain Provisions of Bermuda Law
We have been designated by the Bermuda Monetary Authority as a non-resident for Bermuda exchange control purposes. This designation allows us to engage in transactions in currencies other than the Bermuda dollar, and there are no restrictions on our ability to transfer funds (other than funds denominated in Bermuda dollars) in and out of Bermuda or to pay dividends to U.S. residents who are holders of our common shares or preferred shares.
The Bermuda Monetary Authority has given its consent for the issue and free transferability of our common shares and preferred shares to and between non-residents of Bermuda for exchange control purposes, provided our shares remain listed on an appointed stock exchange, which includes the New York Stock Exchange. Approvals or permissions given by the Bermuda Monetary Authority do not constitute a guarantee by the Bermuda Monetary Authority as to our performance or our creditworthiness.
In accordance with Bermuda law, share certificates are only issued in the names of companies, partnerships or individuals. In the case of a shareholder acting in a special capacity (for example as a trustee), certificates may, at the request of the shareholder, record the capacity in which the shareholder is acting. Notwithstanding such recording of any special capacity, we are not bound to investigate or see to the execution of any such trust. We will take no notice of any trust applicable to any of our shares, whether or not we have been notified of such trust.
STOCKHOLDER RIGHTS PLAN
We have adopted a shareholder rights plan, commonly referred to as a poison pill. The shareholder rights plan is designed to reduce the likelihood that a potential acquirer would gain control of Nabors by open market accumulation or other tactics without paying an appropriate premium for all of Nabor’s shares. Under the plan, each of our common shares issued before May 15, 2020 is accompanied by the right described in the next sentence. Each right entitles shareholders to buy, upon occurrence of certain events, one one-thousandth of a share of a new series of participating preferred shares at an exercise price of $58.08. The rights generally will be exercisable only if a person or group acquires beneficial ownership of 4.9% or more of our share capital, or commences a tender or exchange offer that, upon consummation, would result in a person or group beneficially owning 4.9% or more of our share capital, subject to certain exceptions. Under certain circumstances the rights are redeemable at a price of $0.01 per right. Unless earlier exchanged, redeemed, amended or exercised, the rights will expire on April 30, 2021.

General

The preferred shares of any series underlying the depositary shares will be deposited under a separate deposit agreement between usNabors and a bank or trust company we select. The prospectus supplement relating to a series of depositary shares will set forth the name and address of this preferred share depositary. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, proportionately, to all the rights, preferences and privileges of the preferred share represented by such depositary share (including dividend, voting, redemption, conversion, exchange and liquidation rights).
The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement, each of which will represent the applicable interest in a number of shares of a particular series of the preferred shares described in the applicable prospectus supplement.
A holder of depositary shares will be entitled to receive the preferred shares (but only in whole preferred shares) underlying those depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the whole number of preferred shares to be withdrawn, the depositary will deliver to that holder at the same time a new depositary receipt for the excess number of depositary shares. 23 DIVIDENDS AND OTHER DISTRIBUTIONS
Dividends and other distributions
The preferred share depositary will distribute all cash dividends or other cash distributions in respect of the preferred shares to the record holders of depositary receipts in proportion, insofar as possible, to the number of depositary shares owned by those holders.
If there is a distribution other than in cash in respect of the preferred shares, the preferred share depositary will distribute property received by it to the record holders of depositary receipts in proportion, insofar as possible, to the number of depositary shares owned by those holders, unless the preferred share depositary determines that it is not feasible to make such a distribution. In that case, the preferred share depositary may, with our approval, adopt any method that it deems equitable and practicable to effect the distribution, including a public or private sale of the property and distribution of the net proceeds from the sale to the holders.
The amount distributed in any of the above cases will be reduced by any amount we or the preferred share depositary are required to withhold on account of taxes. CONVERSION AND EXCHANGE

REDEMPTION OF DEPOSITARY SHARES
Redemption of depositary shares
Whenever we redeem a preferred share held by the preferred share depositary, the preferred share depositary will redeem as of the same redemption date a proportionate number of depositary shares representing the preferred shares that were redeemed. The redemption price per depositary share will be equal to the aggregate redemption price payable with respect to the number of preferred shares underlying

32


the depositary shares. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or proportionately as we may determine.
After the date fixed for redemption, the depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of the depositary shares will cease, except the right to receive the redemption price. VOTING
Voting
Upon receipt of notice of any meeting at which the holders of any preferred shares underlying the depositary shares are entitled to vote, the preferred share depositary will mail the information contained in the notice to the record holders of the depositary receipts.
