Note 4 – Other revenue

The Company has a grant from a government-sponsored entity for research and development related activities that provides payments for reimbursed costs, which included overhead and general and administrative costs, as well as an administrative fee. The Company recognizes revenue from grants as it performed services under this arrangement. Associated expenses are recognized when incurred as research and development expense. There was no grant revenue recognized for the six months ended June 30, 2024 and 2023, respectively.

On April 7, 2022, the Company entered into a license and supply agreement (the “License Agreement”) with Immedica Pharma AB (“Immedica”), pursuant to which Immedica licensed the exclusive product rights for commercialization of Iomab-B (I-131 apamistamab) in the European Economic Area, Middle East and North Africa (EUMENA) including Algeria, Andorra, Bahrain, Cyprus, Egypt, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Libya, Monaco, Morocco, Oman, Palestine, Qatar, San Marino, Saudi Arabia, Switzerland, Syria, Tunisia, Turkey, the United Arab Emirates, the United Kingdom, the Vatican City and Yemen. Upon signing, the Company was entitled to an upfront payment of $35 million from Immedica, which was received in May 2022. Under the terms of the License Agreement, the Company is eligible to receive regulatory and commercial milestone payments and is entitled to receive royalties in the mid-20 percent range on net sales of the product in certain countries that may result from the License Agreement. The Company will continue to be responsible for certain clinical development activities and the manufacturing of Iomab-B and will retain commercialization rights in the U.S. and rest of the world.

The Company’s contract liabilities are recorded within Other revenue deferred – current liability or Long-term license revenue deferred in its condensed consolidated balance sheets, depending on the short-term or long-term nature of the payments to be recognized. The Company’s contract liabilities primarily consist of advanced payments from licensees. Long-term license revenue deferred was $35.0 million at June 30, 2024 and December 31, 2023; this deferred revenue will be recognized upon European Union regulatory approval of Iomab B.
