[1] In June 2026, the Company entered into agreements to repurchase a portion of its 2029 Notes, which settled in July 2026. The derivative liability associated with the repurchased notes was derecognized upon signing of the note repurchase agreements with the noteholders. 
[2] The current payment obligation related to the 2029 Notes repurchase obligation is classified as a Level 2 liability. The fair value was determined using the contractual settlement formula in the note repurchase agreements and observable volume weighted average price data for the Company's common stock during the measurement period. Accordingly, the fair value at June 30, 2026 approximated the contractual settlement amount. (See “Note 6 — Debt” for additional information regarding the repurchase transaction.)
