There were no material fair value measurements related to impairments of long-lived assets during the year ended December 31, 2024 (Successor), and for the period from May 18 through December 31, 2023 (Successor) See Note 7 for information on the nonrecurring fair value measurement of Brandon Shores and Note 20 for information on the nonrecurring fair value measurements resulting in the application of fresh start accounting during the period from January 1 through May 17, 2023 (Predecessor).

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.
