Collaboration Agreement with AbbVie |
Collaboration Agreement with AbbVie | 3. Collaboration Agreement with AbbVie In January 2023, the Company entered into the Collaboration Agreement with AbbVie, pursuant to which the Company will use its proprietary discovery engine to discover and validate targets derived from patients with three specified tumor types, and antibodies that bind to such targets, which may be the subject of further development and commercialization by AbbVie. Pursuant to the terms of the Collaboration Agreement, the Company granted to AbbVie an exclusive option to purchase all rights to each novel target-antibody pair, or a Validated Target Pair or VTP, that the Company generates that meets certain mutually agreed criteria, up to a maximum of 10 in total, for all human and non-human diagnostic, prophylactic and therapeutic uses throughout the world, including the development and commercialization of certain products, or Products, derived from the assigned VTP. AbbVie paid the Company a nonrefundable upfront payment of $30.0 million in January 2023 and will pay certain additional platform access payments in the aggregate amount of up to $70.0 million based on the Company’s use of its discovery engine in connection with activities under each stage of the research plan, and delivery of VTPs to AbbVie. AbbVie will also pay an option exercise fee in the low single digit millions for each of up to 10 VTPs for which it exercises an option. If AbbVie progresses development and commercialization of a Product, AbbVie will pay the Company development and commercial sale milestones of up to $120.0 million per target, and sales milestones based on achievement of specified levels of net sales of Products of up to $150.0 million in the aggregate per Product, subject to specified deductions in certain circumstances. On a Product-by-Product basis, AbbVie will pay the Company tiered royalties on net sales of Products at a percentage in the low single digits, subject to specified reductions and offsets in certain circumstances. AbbVie’s royalty payment obligation will commence, on a Product-by-Product and country-by-country basis, on the first commercial sale of such Product in such country and will expire on the earlier of (a) the later of (i) the ten-year anniversary of the first commercial sale for such Product in such country, or (ii) solely with respect to a Product that incorporates an antibody comprising a VTP (or certain other antibodies derived from such delivered antibody), the expiration of all valid claims of patent rights covering the composition of matter of any such antibody and (b) the expiration of regulatory exclusivity for such Product in such country. The Collaboration Agreement will expire upon the expiration of the last to expire royalty payment obligation with respect to all Products in all countries, subject to earlier expiration if all option exercise periods for all VTPs expire without AbbVie exercising any option, if AbbVie does not elect to make certain platform access payments at specified points during the research term, or upon the uncured material breach or any insolvency event of either party. AbbVie may also terminate the Collaboration Agreement for convenience upon a specified period prior written notice, or upon the Company’s breach of representations and warranties with respect to debarment or compliance with anti-bribery and anti-corruption laws. The Company assessed the Collaboration Agreement under ASC 808 and ASC 606 and concluded that it represents a contract with a customer. The Company applied the relevant guidance of ASC 606 to evaluate the accounting under the Collaboration Agreement and identified one performance obligation under the arrangement: a promise to provide research and development services to AbbVie, or R&D Services. The Company evaluated the options to continue the R&D services and options to purchase licenses to each VTP and concluded that these options did not represent material rights. The Company determined the initial transaction price of the single performance obligation to be $30.0 million, as the variable consideration for additional R&D services, option exercise payments, and development milestone payments are all subject to constraint at contract inception. At each reporting period, the Company will reevaluate the variable consideration subject to constraint and, if necessary, will adjust its estimate of the overall transaction price. For the sales-based royalties, the Company will recognize revenue when the related sales occur. Collaboration revenue from the single performance obligation will be recognized over the estimated performance of the R&D services using the cost-to-cost input method which the Company believes best depicts the transfer of control to the customer. Under the cost-to-cost input method, the extent of progress towards completion is measured based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying the performance obligation. The Company recognized $4.3 million and $6.6 million of collaboration revenue for the three and six months ended June 30, 2023, respectively. The following table summarizes the change in deferred revenue (in thousands):
​ | ​ | ​ | ​ | ​ | ​
​ | Three Months Ended June 30, 2023 |  | Six Months Ended June 30, 2023
Balance at the beginning of the period | $ | 27,636 | ​ | $ | —

Recognition of unearned revenue |  | (4,263) | ​ |  | (6,627)
Balance at the end of the period | $ | 23,373 | ​ | $ | 23,373
​ As of June 30, 2023, the Company expects to recognize the deferred revenue associated with the non-refundable upfront fee over the estimated research and development period of approximately 1.5 years.
