In February 2019, the Company acquired 100% of the outstanding equity in Cobalt Biomedicine, Inc. (Cobalt), a privately-held early-stage biotechnology company that was developing a platform technology using its fusogen technology to specifically and consistently deliver various biological payloads to cells.

As part of the Cobalt acquisition, the Company recorded an intangible asset of $59.2 million, which consists of in-process research and development that is classified as indefinite-lived until the successful development of the associated research and development technology, at which point it becomes a finite-lived asset and will be amortized over its estimated useful life. If the research and development technology is abandoned, an impairment charge will be recorded. The Company is actively developing the fusogen technology and, accordingly, development of the intangible asset is not complete. Amortization will begin when regulatory approval is obtained in a major market, typically either the United States or the European Union.

The Company recognized $140.6 million of goodwill as a result of the Cobalt acquisition, which is primarily attributable to the value the acquisition provides the Company by complementing the Company’s ex vivo portfolio with in vivo cell engineering technology and furthering the Company’s research in using engineered cells as medicines. The goodwill is not deductible for income tax purposes. There were no impairments of the intangible asset or goodwill since the acquisition.

Pursuant to the terms and conditions in the Cobalt acquisition agreement, the Company has an obligation to pay certain former Cobalt stockholders up to an aggregate of $500.0 million in contingent consideration (Cobalt Contingent Consideration) upon the achievement of certain pre-specified development milestones, and a success payment (Cobalt Success Payment) of up to $500.0 million, payable in cash or stock. The Cobalt Success Payment is payable if, at pre-determined valuation measurement dates which include the closing of the Company’s IPO and periodically thereafter, the Company’s market capitalization equals or exceeds $8.1 billion, and the Company is advancing a program based on the fusogen technology in a clinical trial pursuant to an investigational new drug application, or has filed for, or received approval for, a biologics license application or new drug application. The Cobalt Success Payment can be achieved over a maximum of 20 years from the date of the acquisition, but this period could be shorter upon the occurrence of certain events. As of June 30, 2022, a Cobalt Success Payment had not been triggered.

A valuation measurement date would also be triggered upon a change of control of the Company if at least one Company product based on the fusogen technology is the subject of an active research program at the time of such change of control. If there is a change of control and the Company’s market capitalization is below $8.1 billion as of the date of the change of control, the amount of the potential Cobalt Success Payment will decrease, and the amount of potential Cobalt Contingent Consideration will increase.

The following table sets forth various thresholds for the Company’s market capitalizations as of the date of a change of control and the resulting potential Cobalt Success Payment and additional potential Cobalt Contingent Consideration:

Sana market capitalization upon a change of control and resulting impact to Cobalt Success Payment and additional potential Cobalt Contingent Consideration	Cobalt Success Payment		Additional potential Cobalt Contingent Consideration
	(in millions)
Equal to or exceeds $8.1 billion	$	500	$	-
Equal to or exceeds $7.4 billion, but less than $8.1 billion		150		350
Equal to or exceeds $6.8 billion, but less than $7.4 billion		100		400
Less than $6.8 billion		-		500

The Cobalt Success Payment and Cobalt Contingent Consideration liabilities are carried at fair value, with changes in fair value recognized in the statements of operations in research and development related success payments and contingent consideration. As of June 30, 2022 and December 31, 2021, the estimated fair value of the Cobalt Success Payment liability was $29.5 million and $88.3 million, respectively, and was recorded in long-term liabilities in the balance sheets. In connection with the change in the estimated fair value of the Cobalt Success Payment, the Company recognized gains of $12.1 million and $66.6 million for the three months ended June 30, 2022 and 2021, respectively, and a gain of $58.9 million and expense of $25.1 million, for the six months ended June 30, 2022 and 2021, respectively.

As of June 30, 2022, the estimated fair value of the Cobalt Contingent Consideration was $149.4 million, of which $51.4 million was recorded in short-term liabilities and $98.0 million was recorded in long-term liabilities in the balance sheet. As of December 31, 2021, the estimated fair value of the Cobalt Contingent Consideration was $153.7 million, of which $51.4 million was recorded in short-term liabilities and $102.3 million was recorded in long-term liabilities in the balance sheet. In connection with the change in the estimated fair value of the Cobalt Contingent Consideration, the Company recognized a gain of $3.8 million and an expense of $7.2 million for the three months ended June 30, 2022 and 2021, respectively, and a gain of $4.4 million and an expense of $18.6 million for the six months ended June 30, 2022 and 2021, respectively.
