On February 2, 2022, the Company entered into the Rewrite Merger Agreement. Under the Rewrite Merger Agreement, the Company paid the Rewrite Holders upfront consideration in an aggregate amount of $45.0 million, excluding customary purchase price adjustments and closing costs, payable in cash. Pursuant to the Rewrite Merger Agreement, the Company acquired all of the issued and outstanding shares of Rewrite. The Rewrite transaction resulted in the acquisition of certain know-how and IP assets related to Rewrite’s proprietary DNA writing technology. The Company's management determined that the acquired assets do not meet the definition of a business pursuant to ASC 805, Business Combinations, as substantially all of the fair value of the acquired assets is concentrated into one identifiable asset, the DNA writing technology. As of the date of closing of the

transactions contemplated by the Rewrite Merger Agreement (the “Rewrite Merger Agreement Date”), the asset acquired had no alternative future use and had not reached a stage of technological feasibility. As a result, all payment obligations have been recorded as research and development expense in the condensed consolidated statements of operations and other comprehensive loss in the amount of $56.0 million. The total transaction price was allocated to the assets acquired and liabilities assumed on a relative fair value basis.

In addition, the Rewrite Holders are eligible to receive up to an additional $155.0 million in milestone payments upon the achievement of certain pre-specified research and regulatory approval milestones, payable through a mixture of $130.0 million in cash and $25.0 million in a combination of cash and the Company’s common stock which will be valued using the volume-weighted average price of the Company’s Common Stock over the ten consecutive trading day period ending on and including the trading day that is two trading days immediately prior to the issuance of the consideration issued in connection with the applicable milestone.

The Company determined that the research milestone settled in the Company’s common stock is classified as a contingent consideration liability under ASC 480 and, therefore, the Company recorded a liability for this milestone payment as of the Rewrite Merger Agreement Date at its fair value of $10.5 million. The contingent consideration liability is remeasured at fair value each financial reporting period, with the resulting impact reflected in the Company’s condensed consolidated statements of operations and other comprehensive loss, presented within other (expense) income. The milestones that will be settled in cash will be recorded when the contingency is resolved and the consideration is paid or becomes payable. As of September 30, 2022, none of the milestones that will be settled in cash were resolved.
