Risks and uncertainties related to the proposed transaction include, but are not limited to: the failure of Nabors’ shareholders or Parker’s shareholders to approve the proposed transaction; the risk that the conditions to the closing of the proposed transaction are not satisfied; the risk that regulatory approvals required for the proposed transaction are not obtained or are obtained subject to conditions that are not anticipated; potential adverse reactions or changes to business relationships resulting from the announcement or completion of the proposed transaction; uncertainties as to the timing of the proposed transaction; competitive responses to the proposed transaction; costs and difficulties related to the integration of Parker’s businesses and operations with Nabors’ business and operations; the inability to obtain, or delays in obtaining, cost savings and synergies from the proposed transaction; unexpected costs, charges or expenses resulting from the proposed transaction; litigation relating to the proposed transaction; the inability to attract, retain or motivate key personnel; changes in the market value of Nabors common shares as a result of the announcement of the proposed transaction; any changes in general economic and/or industry specific conditions; and other risks and uncertainties described in the Nabors’ periodic reports on Forms 10-K and 10-Q that Nabors files with the SEC.

Important Additional Information and Where to Find It

In connection with the proposed transaction Nabors will file with the SEC a Registration Statement on Form S-4 to register the shares of Nabors capital stock to be issued in connection with the proposed transaction. The Registration Statement will include a joint proxy statement/prospectus of Nabors and Parker. The definitive joint proxy statement/prospectus will be sent to the shareholders of each of Nabors and Parker seeking their approval of the proposed transaction and other related matters.

WE URGE INVESTORS AND SECURITY HOLDERS TO READ THE REGISTRATION STATEMENT ON FORM S-4 AND THE JOINT PROXY STATEMENT/PROSPECTUS INCLUDED WITHIN THE REGISTRATION STATEMENT ON FORM S-4 AND ANY OTHER RELEVANT DOCUMENTS WHEN THEY BECOME AVAILABLE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT PARKER, NABORS AND THE PROPOSED TRANSACTION.

Participants in the Solicitation

A description of participants’ direct or indirect interests, by security holdings or otherwise, will be included in the joint proxy statement/prospectus relating to the proposed transaction when it is filed with the SEC. Information regarding Nabors’ directors and executive officers is available in its proxy statement filed with the SEC on April 25, 2024 in connection with its 2024 annual meeting of shareholders (the “Annual Meeting Proxy Statement”) under “Proposal 1-Election of Directors- Director Nominees,” “Proposal 1-Election of Directors-Other Executive Officers,” “Compensation Discussion and Analysis” and “Share Ownership of Directors and Executive Officers.” To the extent holdings of securities by potential Nabors participants (or the identity of such participants) have changed since the information printed in the Annual Meeting Proxy Statement, such information has been or will be reflected on Nabors’ Statements of Change in Ownership on Forms 3 and 4 filed with the SEC.
