DURHAM, N.C., Sept. 30, 2019 (GLOBE NEWSWIRE) -- ?Dova Pharmaceuticals, Inc. (NASDAQ:DOVA) announced today it has entered into an agreement and plan of merger with Swedish Orphan Biovitrum AB (Sobi) (OM:SOBI). Under the terms of the agreement, an indirect subsidiary of Sobi will commence a tender offer for all outstanding shares of Dova, whereby Dova stockholders will be offered an upfront payment for $27.50 per share in cash, along with one non-tradeable Contingent Value Right (CVR) that entitles them to an additional $1.50 per share in cash upon regulatory approval of DOPTELET for the treatment of chemotherapy-induced thrombocytopenia (CIT), representing a total potential consideration of $29.00 per share, or a total potential consideration of up to $915 million on a fully diluted basis.

The upfront consideration of $27.50 per share represents a premium of 36% to Dova?s closing price on September 27, 2019 and a premium of 59% to the 30-day volume weighted average price. The transaction was unanimously approved by the Boards of Directors of both companies and is expected to close in the fourth quarter of 2019.

The proposed transaction is anticipated to enhance Sobi?s position as a leader in hematology and orphan diseases and expand its presence in the United States. Additionally, Sobi intends to leverage its strong international presence to maximize the availability and commercial potential of DOPTELET globally.

?We are extremely pleased to announce this merger with Sobi, which we believe will continue the expansion of DOPTELET in the U.S., and provide the necessary resources to maximize DOPTELET?s availability to patients in both the US and internationally,? said David Zaccardelli, PharmD, President and Chief Executive Officer of Dova. ?On behalf of the Board of Directors, I?d like to thank our employees and shareholders for their continued support and dedication to our mission of providing novel and effective therapeutic options for patients with thrombocytopenia; we believe Sobi is ideally positioned to continue that mission.?

Guido Oelkers, PhD, President and Chief Executive Officer of Sobi, commented, ?The cadence of upcoming launches and approvals across indications and regions that Doptelet provides, enables us to further accelerate growth in our haematology franchise. There is a large unmet medical need within thrombocytopenia and for us this is a great opportunity to be able to give patients access to new and improved treatments. Furthermore, we are excited to welcome the 125 professionals from Dova who will greatly strengthen Sobi?s haematology infrastructure and broaden our value chain in the US.?

Transaction Details

Under the terms of the agreement, an indirect subsidiary of Sobi will commence a tender offer for all outstanding shares of Dova, whereby Dova stockholders will be offered an upfront payment for $27.50 in cash, along with one non-tradeable CVR of $1.50 per share. The non-tradeable CVR will be paid upon the regulatory approval of DOPTELET for the treatment of CIT. There can be no assurance such approval will occur or that any contingent payment will be made.

Sobi will acquire any shares of Dova not tendered into the tender offer through a merger for the same per share consideration as will be payable in the tender offer.
