Capital Drilling Limited("Capital Drilling", the "Group" or "the Company")

PROPOSED SECONDARY PLACING

Capital Drilling (LSE: CAPD), a leading drilling solutions company focused on emerging and developing markets, announces that certain Directors and founding shareholders (the "Vendors") of the Company intend today to sell approximately 25,000,000 ordinary shares of US$0.0001 each in the Company (the "Placing Shares") at a price of 48p per Placing Share (the "Placing"). The Placing Shares represent approximately £12 million in value and 18.5 per cent. of the issued share capital of the Company.

The Vendors are undertaking the Placing in response to institutional demand for the Placing Shares and in order to increase the Company's free float and facilitate more liquidity in the trading of the Company's shares. The Vendors each propose to sell such number of Placing Shares as is pro rata to their existing shareholding in the Company.

Following completion of the Placing, the Vendors and, in particular the Directors, will continue to be substantial shareholders in the Company and will remain fully aligned with its success. None of the Vendors have any present intention to sell any further shares in the Company following completion of the Placing.

The completion of the Placing and number of Placing Shares to be sold is at the sole discretion of the Vendors. Completion of the Placing and the resulting Directors' shareholdings will be announced as soon as practicable.
