The Company performs routine procedures such as comparing prices obtained from independent sources to ensure that appropriate fair values are recorded. The cash equivalents and Public Warrants are categorized as Level 1 instruments as the fair value was determined based on the unadjusted quoted prices are available in active markets for identical assets or liabilities as of the reporting date. The marketable securities, derivative asset and derivative liability are categorized as Level 2 instruments as the estimated fair value was determined based on the estimated or actual bids and offers of the marketable securities in an over-the-counter market on the last business day of the period. The Private Placement Warrants are classified within Level 2 because the transfer of Private Placement Warrants to anyone outside of certain permitted transferees of Artius Acquisition Partners LLC (the “Sponsor”) would result in the Private Placement Warrants having substantially the same terms as the Public Warrants, the Company determined that the fair value of each Private Placement Warrant is consistent with that of a Public Warrant. Accordingly, the Private Placement Warrants are classified as Level 2 financial instruments.
The value of the earnout liability is classified as Level 3 measurements under the fair value hierarchy, as these liabilities have been valued based on significant inputs not observable in the market (see Note 9 for additional details). A gain of zero and $2.5 million during the three and six months ended June 30, 2025, respectively, and a loss of $1.0 million and a gain of $0.5 million during the three and six months ended June 30, 2024, respectively, was recorded on the unaudited condensed consolidated statements of operations and comprehensive loss in the gain (loss) in fair value of earnout liability.
The following table summarizes the activities for the earnout liability during the three and six months ended June 30, 2025 and 2024:

As of June 30, 2025 and December 31, 2024, the carrying values of accounts receivable and unbilled receivable, other receivables, accounts payable, and accrued expenses approximate their respective fair values due to their short-term nature. We have determined the fair value of notes payable and Canadian government research and development program liability approximates the carrying value due to the standard terms of the arrangement including but not limited to the amount borrowed, the term, and the interest rate.
Marketable Securities
The Company’s marketable securities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. Amortized cost net of unrealized gain (loss) is equal to fair value. The following table summarizes the marketable securities by major security type as follows:

The realized gains and losses are included in other income (expenses), net in the unaudited condensed consolidated statements of operations and comprehensive loss.
We sold marketable securities for proceeds of $658.6 million and $805.3 million during the six months ended June 30, 2025 and 2024, respectively. As a result of those sales, we realized a gain of $0.1 million and a loss of less than $0.1 million during the three and six months ended June 30, 2025, respectively, and a gain of $0.1 million during each of the three and six months ended June 30, 2024. We regularly review our available-for-sale marketable securities in an unrealized loss position and evaluate the current expected credit loss by considering factors such as historical experience, market data, issuer-specific factors, and current economic conditions. The aggregate fair value of the marketable securities in an unrealized loss position was $18.8 million and $26.6 million as of June 30, 2025 and December 31, 2024, respectively. The unrealized losses were attributable to changes in interest rates that impacted the value of the investments, and not related to increased credit risk. Accordingly, we have not recorded an allowance for credit losses associated with these investments.
The contractual maturities of the investments classified as marketable securities are as follows:

Derivative Assets and Liabilities
The Company entered into foreign currency derivative contracts with financial institutions to reduce foreign exchange risk related to certain marketable securities denominated in foreign currency. Foreign currency derivative contracts are marked-to-market at the end of each reporting period with gains and losses recognized as other income (expenses). The Company recognized a net loss of less than $0.1 million during each of the three and six months ended June 30, 2025, and a loss of less than $0.1 million and a net gain of $0.3 million during the three and six months ended June 30, 2024, respectively, on the fair value adjustment of the foreign currency derivative contracts. The notional amount of foreign currency derivative contracts as of June 30, 2025 and December 31, 2024 was $3.1 million and $1.2 million, respectively.
