Aspen Insurance Holdings Ltd, the Bermudian-domiciled insurer, is a step closer to becoming a public company.

Aspen announced that it has filed a registration statement on Form F-1 with the US Securities and Exchange Commission relating to a proposed underwritten initial public offering of its ordinary shares.

A company statement said: “The timing of the offering, number of ordinary shares to be offered and the price range for the proposed offering have not yet been determined.

“The ordinary shares to be offered and sold in the proposed offering are expected to be offered by Aspen and certain selling shareholders. The initial public offering is subject to market and other conditions.”

Aspen added: “A registration statement relating to the ordinary shares has been filed with the SEC but has not yet become effective. The ordinary shares may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective.”

The company said Goldman Sachs & Co LLC, Citigroup, Jefferies and Apollo Global Securities are acting as joint book-running managers for the proposed offering, which will be made only by means of a prospectus.

News of the filing comes a week after Aspen confirmed that it was contemplating an IPO next year.

That confirmation followed a report by the Financial Times that Aspen was planning to hold its $4 billion IPO in New York instead of London.

The filing with the SEC appears to confirm that report.

Two Bermudian-based entities, Fidelis and Hamilton Insurance, have this year launched IPOs on the New York Stock Exchange.
