PROSPECTUS 13,513,514 Common Shares North Atlantic Drilling Ltd. Common Shares North Atlantic Drilling Ltd. is offering 13,513,514 of its common shares. This is our initial public offering in the United States and currently our common shares are not listed on any United States securities exchange. The initial public offering price is $9.25 per share. References in this prospectus to common shares are adjusted to reflect the consolidation of our common shares through a one-for-five reverse stock split, which our board of directors made effective as of November 19, 2012. Our common shares are traded on the Norwegian OTC List, an over-the-counter market that is administered and operated by a subsidiary of the Norwegian Securities Dealers Association, under the symbol “NADL.” On December 30, 2013, the closing price of our common shares was 57.50 Norwegian Kroner (“NOK”) per share, which was equivalent to approximately $9.47 per share based on the Bloomberg Composite Rate of NOK6.07 per $1.00 in effect on that date. We completed private offerings in accordance with Regulation S under the Securities Act of 1933, as amended (the “Securities Act”), in February 2011 for 50,000,000 common shares (the “2011 Private Placement”) and in March 2012 for 30,000,000 common shares (the “March 2012 Private Placement”), of which 15,000,000 common shares were acquired by Seadrill Limited (NYSE:SDRL), or Seadrill. Concurrently with this offering, we will offer to exchange the unregistered common shares previously issued in the 2011 Private Placement and the March 2012 Private Placement, other than the common shares owned by Seadrill or other affiliates of ours, for common shares that have been registered under the Securities Act. The sales of substantial amounts of these common shares in the near term, or the perception that these sales may occur, could cause the market price of our common shares to decline. Our common shares have been approved for listing on the New York Stock Exchange under the symbol “NADL,” upon notice of issuance. We were an “emerging growth company”, as defined under the Jumpstart Our Business Startups Act, or JOBS Act, at the time we publicly filed our initial registration statement with the Securities and Exchange Commission. We are eligible for reduced disclosure requirements applicable to emerging growth companies through the effectiveness of this registration statement. See “Summary—Reduced Disclosure Requirements.” Investing in our common shares involves risks. See “Risk Factors” beginning on page 20.
