[1] (1) Certain non-controlling interests are redeemable at the option of the holders. When the estimated redemption value exceeds the recorded amount, the excess is charged directly to Shareholders' equity on the Consolidated Balance Sheets. This adjustment does not affect the Company's reported net loss; however, under ASC 480-10, Distinguishing Liabilities from Equity, the excess redemption value must be included in the calculation of earnings per share - basic and diluted. See Note 2 — Basis of presentation and consolidation and Note 24 — Earnings per share for further details.

[2] (2) As a result of the Company’s net losses from its continuing and discontinued operations for the years ended December 31, 2025 and 2024, the calculation of diluted net loss per share for each period presented gives no consideration to potentially anti-dilutive securities; and as such, is the same as basic net loss per share for each period presented.
