2023 Lilly License
On April 26, 2023, our newly formed subsidiary ZB17 LLC (“ZB17”) entered into a license agreement (the “2023 Lilly License” and, together with the 2022 Lilly License, the “Lilly Licenses”) with Lilly, for an exclusive license to develop, manufacture and commercialize a certain bispecific antibody relating to IL-17 and BAFF (“ZB-106”). ZB17 made a payment of $5.0 million to Lilly during the nine months ended September 30, 2024, in connection with the receipt of certain know-how, data, information and materials that Lilly was required to provide under the license agreement.
As a finder’s fee for arranging the acquisition of the 2023 Lilly License, ZB17 granted Stone Peach the right, but not the obligation, to purchase 4.99% of the fully diluted equity of ZB17 for $1.0 million (the “Stone Peach Call Right”). The Stone Peach Call Right is not exercisable until after the last patient is dosed in any single next clinical trial with ZB-106 and expires one year from the date of first indication approval for ZB-106 by the FDA or the European Medicines Agency (“EMA”). The Stone Peach Call Right represents noncontrolling interest in our subsidiary, ZB17.
As additional consideration, Stone Peach receives annual payments first of $0.6 million, and increasing by 10% annually, so long as we maintain our license for ZB-106 on May 1st of each year. An annual payment of $0.7 million became due and was paid during the three months ended June 30, 2024.
As a finder’s fee for arranging the acquisition of the 2023 Lilly License, we agreed to make a one-time milestone payment of $5.0 million to BAFFX17, Ltd (“BAFFX17”) upon the occurrence of either: (i) a change of control transaction, (ii) our closing of an issuance of equity or equity-linked securities of at least $100.0 million (iii) the consummation of a sale of assets resulting in net proceeds in excess of $100.0 million, or (iv) our fully diluted shares outstanding exceed 52,500,000 shares (on a split adjusted basis). As our fully diluted shares outstanding exceeded 52,500,000 shares prior to December 31, 2023, the $5.0 million fee was recorded in accounts payable and accrued expenses in the condensed consolidated balance sheet as of September 30, 2024.
