Borr Drilling Limited (BDRILL) – Notice of Special General Meeting of Shareholders

Bermuda 23 March 2018

Borr Drilling Limited (the “Company”) announces that a Special General Meeting of the Shareholders of the Company will be held on 5 April 2018 at 10 a.m., at Thistle House, 4 Burnaby Street, Hamilton, Bermuda. A copy of the Notice of Special General Meeting will be sent out to the Company’s shareholders, and can be found on the Company’s website and enclosed to this press release.

The special general meeting is convened in order to consider a proposal by the board to increase the authorised share capital in the company by USD 1 million represented by 100 million shares.

The increase is required in order to enable the Board to issue new shares to complete the share issue announced on 23 March 2018, and to issue shares in response to future declarations of options by employees of the Company.

This will furthermore enable the Board to complete the equity financing of the Company. The authorisation of this capital is likely sufficient to equity fund the few remaining interesting investment opportunities the Board sees within the market for high specification jack-up rigs. This will complete the successful growth period of Borr Drilling Limited of acquiring a brand-new jack-up fleet consisting of 22 units built after 2011 at a significant discount to newbuilding prices.

Subsequent to this active acquisition period, focus will be on operation and marketing of our fleet and return of capital to the Company’s shareholders.
