Biota and Nabi Announce Proposed Merger

Marketwired

MELBOURNE, AUSTRALIA--(Marketwire -04/23/12)- Biota Holdings Limited (ASX: BTA.AX - News) and Nabi Biopharmaceuticals (NASDAQ: NABI - News) today announced the signing of a Merger Implementation Agreement to form a combined company Biota Pharmaceuticals, listed on NASDAQ and headquartered in the USA.

The Biota move to the US is designed to achieve better value recognition through a stronger US shareholder base.

Following the merger, Biota Pharmaceuticals will have three royalty generating products, Relenza, Inavir and potentially PhosLyra; a US$231 million contract with BARDA for the advanced development of laninamivir; a portfolio of clinical and pre-clinical programs comprising vapendavir (HRV), and programs for respiratory syncytial virus (RSV), hepatitis C (HCV-NN), broad spectrum antibiotic targeting gyrase (GYR); an interest in NicVAX and over US$100 million in cash.

The merger will require approval from both Biota and Nabi shareholders and Independent Reports confirming that the merger will be in the best interest of the shareholders and is subject to a number of other conditions set out in the Merger Implementation Agreement (a copy of which is attached to this announcement).

Key elements of the Agreement are:

  • Nabi will acquire all of the shares in BTA for new shares in the name of Biota Pharmaceuticals, a NASDAQ listed company. BTA will be de-listed from the ASX;

  • Nabi's assets at merger will include US$54 million in cash, a right to receive royalties from a marketed product (PhosLyra) and an interest in NicVAX;

  • After the completion of the merger, current Biota shareholders will own approximately 74% of Biota Pharmaceuticals and Nabi shareholders will own approximately 26% of Biota Pharmaceuticals;

  • Nabi plans to return to its existing shareholders cash in excess of the US$54 million required to be held by Nabi at closing, after satisfying certain obligations;

  • Nabi intends to distribute contingent value rights providing payout rights from future sale, transfer, license or similar transactions involving NicVAX; and

  • The Board will consist of six ex Biota Directors including the Chairman and two ex-Nabi Directors. Biota's current CEO and CFO will continue in their roles.

Biota Chairman, Jim Fox, commented, "A NASDAQ listing provides Biota with access to the largest healthcare capital market in the world and will enable us to transform our business model to one which can deliver significantly higher value than the royalty-only model we have historically pursued. We believe this is a necessary step to increase our options for the development and commercialisation of our product portfolio and will ultimately improve the recognition of the underlying value of our product portfolio for our shareholders."

Both Boards consider the merger proposal as being in the best interests of their respective shareholders in the absence of a superior proposal.

The move underpins the established and successful scientific operations in Melbourne (Australia) and Oxford (United Kingdom) with secure funding and the benefits of a broader shareholder base.

Other points of note:

  • The Companies would expect the transaction to close by 30 September after satisfaction of customary closing conditions and regulatory approvals;

  • The Australian aspects of the transaction will be completed through a Scheme of Arrangement; and

  • It is intended that after an effective transition, the Board will adopt a greater US focus and that the CEO and CFO positions will relocate to the US.

Biota Holdings and Nabi shareholders are not required to take any action now. Further information will be provided to all shareholders in documentation to be provided within the course of the next few weeks.
