Borr Drilling Limited – Announcing Voluntary Delisting from Oslo Stock Exchange

Borr Drilling Limited (the "Company") (NYSE & OSE: BORR) today announced that Euronext Oslo Stock Exchange (“OSE”) has approved the Company’s application for delisting, following an affirmative shareholder vote at the Company’s Special General Meeting in October 2024.

The Company’s shares will be delisted from OSE as of 31 December 2024. The last day of trading will be 30 December 2024, and the Company will subsequently maintain a single listing on the New York Stock Exchange (“NYSE”).

Shareholders holding shares that are traded at the OSE, held through the Norwegian central securities depository held with Euronext Securities Oslo (commonly known as the “VPS”) may divest their shares through open market transactions, or work with their bank or broker to migrate their shares to the Depository Trust Company (DTC) in the US for trading on the NYSE.

The Company intends to maintain its share registration with the VPS for a period of at least 12 months from the effective date of the delisting, allowing shareholders who want to maintain registration of their shares in Euronext Securities Oslo (VPS) to continue trading their shares via a Norwegian broker (outside of the Oslo Stock Exchange) with other investors with shares registered with Euronext Securities Oslo, or migrate their shares to the DTC within such 12-month period.
