5. LICENSE AGREEMENTS

Sopharma License and Supply Agreements

We are party to a license agreement, or the Sopharma License Agreement, and a supply agreement, or the Sopharma Supply Agreement, with Sopharma, AD, or Sopharma. Pursuant to the Sopharma License Agreement, we were granted access to all available manufacturing, efficacy and safety data related to cytisinicline, as well as a granted patent in several European countries related to new oral dosage forms of cytisinicline providing enhanced stability. Additional rights granted under the Sopharma License Agreement include the exclusive use of, and the right to sublicense, certain cytisinicline trademarks in all territories described in the Sopharma License Agreement. Under the Sopharma License Agreement, we agreed to pay a nonrefundable license fee. In addition, we agreed to make certain royalty payments equal to a mid-single digit percentage of all net sales of cytisinicline products in our territory during the term of the Sopharma License Agreement, including those sold by a third party pursuant to any sublicense which may be granted by us. To date, any amounts paid to Sopharma pursuant to the Sopharma License Agreement have been immaterial.

Share Purchase Agreement

On May 14, 2015, we entered into a Share Purchase Agreement with Sopharma to acquire 75% of the outstanding shares of Extab for $2.0 million in cash and $2.0 million in a deferred payment, contingent on regulatory approval of cytisinicline by the FDA or the European Medicines Agency. The fair value of the contingent consideration on the acquisition date was nil. The contingent consideration liability is measured at fair value in our financial statements.

As of June 30, 2024, the fair value of the contingent consideration was estimated to be $0.6 million. We recognized a loss of $0.1 million and $0.1 million for the three and six months ended June 30, 2024, respectively.
