Item 1.01. Entry into Material Definitive Agreement.
On May 27, 2021, Nabors Industries Ltd., a Bermuda exempted company
(the “Company”) announced that the Board of Directors declared a distribution (the “Warrant Distribution”) to
the holders of record of the Company’s common shares, par value $0.05 per share (the “Common Shares”), from contributed
surplus, in the form of warrants to purchase Common Shares (the “Warrants”). The Warrants were issued on the terms and conditions
described in the Warrant Agreement (as defined below and attached as an exhibit hereto) and will be distributed on June 11, 2021,
to the holders of record of Common Shares as of the close of business on June 4, 2021 (the “Distribution Record Date”).
Pursuant to the terms of the Warrant Agreement, dated as of June 10,
2021, between the Company and Computershare Trust Company, N.A., as Warrant Agent (the “Warrant Agreement”), each holder of
record of Common Shares as of the Distribution Record Date will receive two-fifths of a Warrant (rounded down for any fractional Warrant)
per Common Share as of the Distribution Record Date, expected to be approximately 3,742,310 million Warrants in the aggregate.
Each Warrant will represent the right to purchase one Common Share
at an initial exercise price of $166.66667 per Warrant, subject to certain adjustments (the “Exercise Price”). In addition,
Warrants submitted for exercise may be eligible to receive an additional one-third Common Share pursuant to the terms and conditions set
forth in the Warrant Agreement. Payment for Common Shares on exercise of Warrants may be in (i) cash or (ii) Designated Notes,
as defined in the Warrant Agreement, subject to compliance with applicable procedures with respect to the delivery of the Warrants and
Designated Notes. The Exercise Price and the number of Common Shares issuable upon exercise are subject to certain anti-dilution adjustments,
including for share dividends, splits, subdivisions, spin-offs, consolidations, reclassifications, combinations, noncash distributions,
cash dividends, pro rata repurchases, and similar transactions, including certain issuances of Common Shares (or securities exercisable
or convertible into or exchangeable for Common Shares) at a price (or having a conversion price) that is less than 95 % of the market
price of the Common Shares. The Warrants may be exercised up to 5:00 p.m. New York City time on the Expiration Date, as defined in
the Warrant Agreement, which is currently June 11, 2026, but which may be accelerated at any time by the Company upon 20-days’
prior notice. The Company has applied to list the Warrants on the over-the-counter market.
Holders may exercise the Warrants by delivering a completed form of
election to purchase Common Shares and payment of the then-current exercise price in U.S. dollars by certified or official bank check
payable to the order of the Company, or with certain of the Company’s and its subsidiaries’ issued and outstanding notes –
as designated by the Company from time to time – at face value. Upon such delivery, the Company will issue such whole number of
Common Shares as the exercising Warrant holder is entitled to receive. An ownership limitation is in place such that a holder of Warrants
is not permitted to exercise Warrants for any Common Shares if following such exercise the holder will have beneficial ownership of Common
Shares in excess of 4.9% of the then issued and outstanding Common Shares (excluding shares held by subsidiaries); provided, that a holder
of Common Shares in excess of 4.9% of the issued and outstanding Common Shares as of May 27, 2021 will be entitled to exercise Warrants
received in the Warrant Distribution.
The foregoing description of the Warrants and the Warrant Agreement
is only a summary and is qualified in its entirety by reference to the complete description of the terms of the Warrants set forth in
the Warrant Agreement (including the Form of Warrant attached thereto), which is filed as an exhibit to this Form 8-K.
