As previously reported, on July 31, 2020, Noble Corporation plc (the “Company,” “we,” “us” or “our”) and certain of its subsidiaries (the “Debtors”) commenced voluntary cases under chapter 11 of title 11 of the United States Code (the “Chapter 11 Cases”) in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”).

Also as previously reported, on July 31, 2020, the Debtors entered into a Restructuring Support Agreement (together with all exhibits and schedules thereto, the “Restructuring Support Agreement”) with the Consenting Creditors (as defined in the Restructuring Support Agreement).

On November 6, 2020, in connection with the Restructuring (as defined in the Restructuring Support Agreement) and to allow the ultimate parent company that emerges from the Chapter 11 Cases to use the “Noble Corporation plc” name, the Company changed its name to Noble Holding Corporation plc. The name change did not affect the Company’s trading symbol. A copy of the related press release is filed with this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.

Cautionary Information Regarding Trading in the Company’s Securities

The Company cautions that trading in our securities during the pendency of the Chapter 11 Cases is highly speculative and poses substantial risks. Trading prices for the Company’s securities may bear little or no relationship to the actual recovery, if any, by holders of our securities in the Chapter 11 Cases. The Company expects that, other than the possibility of the issuance of very speculative warrants as contemplated by the Restructuring Support Agreement, our equity holders will experience a complete loss on their investment, depending on the outcome of the Chapter 11 Cases.
