During the fiscal years ended December 31, 2025 and 2024, there were no transfers amongst Level 1, Level 2 and Level 3.

We did not recognize any credit losses or non-credit-related impairments related to our available-for-sale marketable debt securities for the years ended December 31, 2025, 2024, and 2023. All unrealized losses were immaterial and recognized in other comprehensive income (loss).

On July 3, 2024, we repurchased a warrant, or the Warrant, to purchase 5 million shares of our Class B common stock for an aggregate purchase price of $61 million, or the Warrant Repurchase. The Warrant was canceled and is no longer outstanding. Immediately prior to the Warrant Repurchase, we recognized a remeasurement gain of $2 million within “Change in fair value of warrant liability” in the Consolidated Statements of Operations for the fiscal year ended December 31, 2024. Upon the Warrant Repurchase, we also recognized a gain on the extinguishment of the Warrant of $14 million within “Other income, net” in the Consolidated Statements of Operations for the fiscal year ended December 31, 2024.

As of December 31, 2025 and 2024, the maximum number of shares of our common stock that could be required to be issued upon the exercise of outstanding warrants was 1 million and 1 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.
