2023 Lilly License
On April 26, 2023, the Company’s 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 six months ended June 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 the Company’s subsidiary, ZB17.
As additional consideration, Stone Peach receives annual payments first of $0.6 million, and increasing by 10% annually, so long as the Company maintains its 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) the closing of an issuance of equity or equity-linked securities by the Company 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) the Company’s fully diluted shares outstanding exceed 52,500,000 shares (on a split adjusted basis). As the Company’s 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 June 30, 2024.
The Company is obligated to make 4 development milestone payments to Lilly up to an aggregate of $155.0 million, and sales milestone payments up to an aggregate of $440 million based on respective thresholds of net sales of products developed from ZB-106. The Company is also obligated to pay Lilly over a multi-year period (twelve years, or upon the later expiration of regulatory exclusivity of ZB-106 in a country) an annual earned royalty at a marginal royalty rate in the mid-single digits to low-double digits, with increasing rates depending on net sales in the respective calendar year, based on a percentage of sales within varying thresholds for a certain period of years. The Company is also obligated to pay BAFFX17 a fee equal to 3% of any milestone or royalty payments due to Lilly pursuant to the terms of either the 2022 Lilly License and the 2023 Lilly License with Lilly. Upon receiving written approval from the FDA, EMA, or similar regulatory authority of the Investigational New Drug (“IND”) and commencement and the commencement of a clinical trial in the applicable jurisdiction for ZB-106, Stone Peach will also receive a one-time payment of $4.5 million. Stone Peach will also receive a one-time milestone payment of $25 million upon either (i) certain equity-related transactions, or (ii) the receipt of regulatory approval from the applicable regulatory authority for any new indication in the applicable jurisdiction. Furthermore, Stone Peach was granted a royalty of 2% of the aggregate net sales of any products developed from the Compound. As of June 30, 2024, none of the contingent payments were due.
2022 Lilly License
On December 8, 2022, the Company’s consolidated subsidiary, Z33 Bio Inc. (“Z33”), entered into a license agreement (the “2022 Lilly License”) with Lilly pursuant to which Lilly granted Z33 an exclusive (even as to Lilly), royalty-bearing global license to develop, manufacture, and commercialize certain intellectual property owned by Lilly relating to its IL-33 compound.
As a finder’s fee in connection with arranging the acquisition, Z33 issued to Stone Peach Properties, LLC (“Stone Peach”) 4,900,222 shares of Z33 Series Seed Preferred Shares, which was included in the measurement of the cost of the acquired asset. As of June 30, 2024, we have the right, but not the obligation to purchase up to 50% of the Series Seed Preferred Shares issued to Stone Peach at a price per share of $2.448869 for a period of two years from the date of the agreement (the “Call Option”). Stone Peach has the right, but not the obligation to sell up to 50% of the Series Seed Preferred Shares issued to Stone Peach to Zura for a price per share of $2.040724 (the “Put Option”). Stone Peach also has the right, but not the obligation to sell up to 50% of the Series Seed Preferred Shares issued to Stone Peach to Zura in exchange for 2,000,000 Class A Ordinary Shares (the “Put Right”). Stone Peach may exercise its Put Option and Put Right at any time between April 24, 2024 and April 24, 2028. The Z33 Series Seed Preferred Shares represent redeemable noncontrolling interest in our subsidiary, Z33.
