Insights

Equity ownership and disclosure analyst

Ownership updated; capped by 19.99% blocker.

Encompass Capital Advisors LLC and Todd J. Kantor each report 44,720,694 shares beneficially owned, equal to 19.99% of T1 Energy’s common stock. Encompass Capital Partners LLC reports 35,890,919 shares, or 16.50%. The positions include common shares, warrants, and shares issuable upon conversion of Convertible Series A Preferred.

The filing specifies a 19.99% beneficial ownership limitation, which constrains conversions that would push ownership above that threshold. This mechanism affects how much preferred can be converted at any time and keeps reported ownership under 20%.

The percentage calculations reference 190,855,046 shares outstanding as of October 24, 2025. Actual impact depends on conversion and exercise decisions within the limitation framework.
