As of December 31, 2025 and 2024, the Company’s cash equivalents consisted of money market funds, which were valued based upon Level 1 inputs. The Company’s marketable securities as of December 31, 2025 consisted of corporate debt securities and U.S. government debt securities, which were all valued based upon Level 2 inputs. The Company’s marketable securities as of December 31, 2024 consisted of commercial paper, corporate debt securities, foreign government agency debt securities, and U.S. government and government agency debt securities, which were all valued based upon Level 2 inputs.

In determining the fair value of its Level 2 investments, the Company relied on quoted prices for identical securities in markets that are not active. These quoted prices were obtained by the Company with the assistance of a third-party pricing service based on available trade, bid and other observable market data for identical securities. During the years ended December 31, 2025 and 2024, there were no transfers into or out of Level 3.

The overall $2.3 million increase in the fair value of the contingent consideration liability during the year ended December 31, 2025 was primarily due to changes to the probability of success for certain product candidates and the passage of time.

As of December 31, 2025 and 2024 the fair value of the Company’s available-for-sale marketable securities by type of security was as follows:

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.
