Note 9 – Bristol-Myers Squibb Collaboration

On January 7, 2022, the Company entered into the Collaboration Agreement with Bristol-Myers Squibb to collaborate on the research, development and commercialization of iNK and iT cell programs for hematologic malignancies and solid tumors (“Collaboration Program”, and each product candidate a “Development Candidate”). The Collaboration Agreement was within the scope of ASC 808, Collaborative Arrangements as both parties were active participants in the arrangement and are exposed to significant risks and rewards. While this arrangement was in the scope of ASC 808, the Company analogizes to ASC 606 for the accounting for the Collaboration Agreement, including for the delivery of goods and services (i.e., units of account). Revenue recognized by analogizing to ASC 606 is recorded as collaboration revenue in the statements of operations.

Pursuant to the Collaboration Agreement, the Company and Bristol-Myers Squibb collaborated on two collaboration programs focused on acute myeloid leukemia (“AML”) and multiple myeloma (“MM”) (“Collaboration Programs”), and Bristol-Myers Squibb had the option to add up to two additional Collaboration Programs for an additional fee. The Company was responsible for generating Development Candidates for each Collaboration Program, and Bristol-Myers Squibb had the option to elect to exclusively license the Development Candidates for pre-clinical development, clinical development and commercialization on a worldwide basis (“License Option”).

Under the terms of the Collaboration Agreement, Bristol-Myers Squibb made a non-refundable, upfront cash payment of $100,000 and agreed to pay an exercise fee upon the exercise of the License Option (“Licensed Program” and product candidates developed under a Licensed Program, “Licensed Products”). For each Licensed Program, Bristol-Myers Squibb agreed to pay up to $235,000 in milestone payments upon the first achievement of certain development and regulatory milestones and agreed to pay up to $500,000 per Licensed Product in net sales-based milestone payments.

In connection with the Collaboration Agreement, Bristol-Myers Squibb purchased 2,160,760 shares of the Company’s common stock at a price per share of $23.14, for an aggregate purchase price of $50,000. In determining the fair value of the common stock issued to Bristol-Myers Squibb, the Company considered the closing price of the common stock on the date of the transaction and included a lack of marketability discount because the shares are subject to certain restrictions. The Company determined the common stock purchase represented a premium of $7.82 per share, or $23,187 in the aggregate (“Equity Premium”), and the remaining $26,813 was recorded as issuance of common stock in stockholders’ equity.

The Company identified the following commitments under the arrangement: (i) research and development services (“R&D Services”) under each of the two initial Collaboration Programs and (ii) Bristol-Myers Squibb’s License Option to elect to exclusively license the Development Candidates for each of the two initial Collaboration Programs. The Company determined that these four commitments represented distinct performance obligations for purposes of recognizing revenue and would have recognized revenue if the Company had fulfilled such performance obligations.

The Company determined that the upfront payment and equity premium constituted the transaction price at the inception of the Collaboration Agreement. The future potential development and regulatory milestone payments were fully constrained at contract inception as the risk of significant revenue reversal related to these amounts has not yet been resolved. The achievement of the future potential milestones was not within the Company’s control and was subject to certain research and development success and therefore carried significant uncertainty.

The total transaction price of $123,187 was allocated to the performance obligations based on their estimated standalone selling price on January 7, 2022. The stand-alone selling price of the research and development services was estimated using the expected cost-plus margin approach, and the stand-alone selling price of the License Options was based on a discounted cash flow approach and considered several factors including, but not limited to, discount rate, development timeline, regulatory risks, estimated market demand, and future revenue potential using an adjusted market approach. The allocated transaction price is recognized as revenue in one of two ways:

Following an internal corporate portfolio prioritization process, Bristol-Myers Squibb notified the Company on December 12, 2024 that it would be terminating the Collaboration Agreement in its entirety without cause. The termination was effective on March 12, 2025. As a result of the notice of termination, the Company concluded that the research and development services being provided to Bristol-Myers Squibb are substantially complete as of December 31, 2024, and accordingly, the remaining transaction price allocated to that performance obligation was recorded in the fourth quarter of 2024. The remaining transaction price related to the license option rights is expected to be recognized in the first quarter of 2025 when the option right expires upon the termination of the Collaboration Agreement.
