Pursuant to the Purchase Agreement, following the satisfaction or waiver of all closing conditions, the Purchaser will pay the Company $122.5 million in cash at closing for the CDMO Operations, subject to customary adjustments, including for working capital and indebtedness. Additionally, the Purchase Agreement provides for up to $5 million of potential additional post-closing cash payments to the Company upon achievement of certain manufacturing milestones by the CDMO Operations and professional development program services to be performed by the CDMO Operations in 2027 and 2028.

In addition, at the closing of the Transaction it is contemplated that the Company will enter into certain customary ancillary agreements, including (i) a manufacturing and supply agreement, pursuant to which the Purchaser will be required to provide certain clinical manufacturing and supply services to the Company, (ii) a transition services agreement, pursuant to which the Purchaser and the Company will provide certain customary transition services to each other for a stated period following the closing, and (iii) a sublease agreement, pursuant to which a portion of the Company's facility located at 9704 Medical Center Drive, Rockville, Maryland will be subleased by Bora to the Company for a period of time. The closing of the Transaction is subject to customary closing conditions.

The Purchase Agreement has been approved by the Boards of Directors of the Company and Bora. The Transaction is expected to close in the third quarter.
