Redeemable noncontrolling interest conditions | The minority Esja shareholders had the right to sell (or “put”) their Esja shares to us based on a multiple of 5.0x EBITDA as calculated on the trailing 12 months from the most recently completed quarter before the put option exercise. The put option was only exercisable after August 2022 (the “Reference Date”), and in the event the Flyover Iceland attraction had earned a minimum of €3.25 million in unadjusted EBITDA during the most recent fiscal year and during the trailing 12-month period prior to exercise (the “Put Option Condition”). The put option was exercisable during a period of 12 months following the Reference Date (the “Option Period”) if the Put Option Condition had been met. If the Put Option Condition had not been met during the first Option Period, the Reference Date was extended for an additional 12 months up to three times. If the Flyover Iceland attraction had not achieved the Put Option Condition by December 31, 2024, the put option would expire. As of December 31, 2024, the Flyover Iceland attraction did not achieve the Put Option Condition and such option expired. The redeemable noncontrolling interest owned by Esja was reclassified to non-redeemable noncontrolling interest and is presented within stockholders’ equity in the Condensed Consolidated Balance Sheets. |
