Additional Information and Where to Find It

In connection with proposed transactions contemplated by the Merger Agreement (the “Business Combination”), on March 19, 2018, Holdco filed a Registration Statement on Form F-4 with the Securities and Exchange Commission (the “SEC”). The Registration Statement, which is not yet effective, includes a preliminary proxy statement/prospectus that is both the preliminary proxy statement to be distributed to holders of the Naked’s common stock in connection with the solicitation by Naked of proxies for the vote by the stockholders on the Business Combination and a preliminary prospectus to be delivered by Holdco in connection with the distribution of its securities to such holders. This material is not a substitute for the final proxy statement/prospectus regarding the proposed Business Combination. The final proxy statement/prospectus will be mailed to stockholders of Naked as of a record date to be established for voting on the proposed business combination. BEFORE MAKING ANY VOTING OR INVESTMENT DECISION WITH RESPECT TO THE BUSINESS COMBINATION, INVESTORS AND SECURITY HOLDERS ARE URGED TO READ THE FINAL PROXY STATEMENT/PROSPECTUS AND OTHER RELEVANT MATERIALS THAT WILL BE FILED WITH THE SEC CAREFULLY AND IN THEIR ENTIRETY WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT NAKED, BENDON AND HOLDCO AND THE PROPOSED BUSINESS COMBINATION. Stockholders will also be able to obtain copies of the Registration Statement which includes the proxy statement/prospectus and other relevant materials containing important information about Naked, Bendon and Holdco, without charge at the SEC’s Internet site at http://www.sec.gov or by directing a request to: Naked Brand Group Inc., 180 Madison Avenue, Suite 1505, New York, New York, 10016, Attention: Investor Relations; and/or on Bendon’s website at www.bendongroup.com or by directing a written request to Bendon Limited, 8 Airpark Drive, Airport Oaks, Auckland 2022, New Zealand or by emailing lucy.martyn@bendon.com.

Participants in the Solicitation

This is not a solicitation of a proxy from any investor or security holder. Naked and its directors and executive officers, under SEC rules, may be deemed to be participants in the solicitation of proxies of Naked’s stockholders in connection with the proposed Merger. Investors and security holders may obtain more detailed information regarding the names and interests in the proposed Merger of Naked’s directors and officers in Naked’s filings with the SEC. Additional information regarding the directors and executive officers of Naked is also included in Naked’s Annual Report on Form 10-K for the year ended January 31, 2017. Information regarding the persons who may, under SEC rules, be deemed participants in the solicitation of proxies to Naked’s shareholders in connection with the proposed Merger will be set forth in the proxy statement/prospectus for the proposed Merger when available. This document will be available free of charge at the SEC’s web site (www.sec.gov) and from Naked’s Investor Relations department at the address described above.

No Offer or Solicitation

This Current Report on Form 8-K shall neither constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which the offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction.

Forward-Looking Statements

Certain statements either contained in or incorporated by reference into this Current Report on Form 8-K, other than purely historical information, including estimates, projections and statements relating to Naked’s or Bendon’s business plans, objectives and expected operating results, and the assumptions upon which those statements are based, are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical facts, included in or incorporated by reference into this communication regarding strategy, future operations, future transactions, future financial position, future revenue, projected expenses, prospects, plans and objectives of management are forward-looking statements.

Naked, Bendon and/or Holdco may not actually achieve the plans, carry out the intentions or meet the expectations disclosed in the forward-looking statements and you should not place undue reliance on these forward-looking statements. Such statements are based on management’s current expectations and involve risks and uncertainties. Actual results and performance could differ materially from those projected in the forward-looking statements as a result of many factors, including, without limitation, risks and uncertainties associated with the ability of Naked, Holdco and Bendon to consummate the transaction contemplated by the Merger Agreement, the risk that one or more of the conditions to closing contained in the Merger Agreement may not be satisfied, including, without limitation, the receipt of stockholder approval of the Naked stockholders, the effectiveness of the Registration Statement or the listing of Holdco’s ordinary shares on the Nasdaq Capital Market, the risk that the parties may otherwise be unable to consummate the proposed business combination, and the risk that competing offers or acquisition proposals will be made.
