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 year. 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 loss of $0.7 million and a gain of $41.0 million for the years ended December 31, 2024 and 2023, respectively, was recorded on the consolidated statements of operations and comprehensive (loss) income in the (loss) gain in fair value of earnout liability.
The following table summarizes the activities for the earnout liability for the years ended:
(in thousands)December 31, 2024December 31, 2023
Balance at beginning of year$1,783 $42,533 
Loss (gain) in fair value of earnout liability703 (40,983)
Other— 233 
Balance at end of year$2,486 $1,783 
As of December 31, 2024 and 2023, 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:

Total marketable securities$86,146 $52 $(3,437)$82,761 
The realized gains and losses are included in other (expenses) income, net in the consolidated statements of operations and comprehensive (loss) income.
We sold marketable securities for proceeds of $1,751.5 million and $3,605.2 million for the years ended December 31, 2024 and 2023, respectively. As a result of those sales, we realized a loss of $0.9 million and a gain of $1.0 million for the years ended December 31, 2024 and 2023, respectively. 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 $26.6 million and $73.2 million as of December 31, 2024 and 2023, 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.

Derivative Asset 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). For the years ended December 31, 2024 and 2023, the Company recognized a net gain of $0.3 million and $0.1 million, respectively, on the fair value adjustment of the foreign currency derivative contracts. The notional amount of foreign currency derivative contracts as of December 31, 2024 and 2023 was $1.2 million and $14.7 million, respectively.

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
