The closing of the transactions contemplated by the asset purchase agreement is subject to certain customary conditions, including the receipt of consent of Roka Bioscience’s lender and approval by the stockholders of Roka Bioscience of the transactions contemplated by the asset purchase agreement. As part of the transaction, Roka Bioscience will be required to make a $2.5 million milestone payment pursuant to its license agreement with Hologic, Inc. The asset sale is the initial step in a contemplated liquidation of Roka Bioscience. Stockholder approval will also be required for the plan of liquidation.

“The announcement of this asset sale follows an extensive review of a range of strategic alternatives for Roka Bioscience, including obtaining further financing to continue as an independent entity and exploring the possibility of mergers and acquisitions,” said Mary Duseau, Chief Executive Officer of Roka Bioscience. “This transaction represents the conclusion of a thorough process. We believe that the asset sale and anticipated liquidation will provide the greatest value to our stockholders.”

Pursuant to the terms of the asset purchase agreement, Roka Bioscience is required to provide transition services to the buyer through no later than December 31, 2017, with the intention of ensuring a successful transition of Roka Bioscience’s business to the buyer. Assuming stockholder approval, liquidating distributions, in an amount to be determined, are expected to begin shortly after the completion of the transition services period.

Roka Bioscience cannot assure you that the conditions to the closing of the transactions contemplated by the asset purchase agreement will be satisfied, or that the transactions will be completed. In the event Roka Bioscience does not successfully complete the transactions contemplated by the asset purchase agreement or complete a transaction resulting from a superior proposal (as described in the asset purchase agreement), Roka Bioscience will have limited options for financing its ongoing operations and will likely cease its operations or file for bankruptcy protection.
