Percentage Recalculation Driven by Green Brick's Updated Share Count

The DME reporting group, which includes DME Advisors GP, L.L.C., DME Advisors, LP, DME Capital Management, LP, and David Einhorn individually, filed this amendment solely to update reported beneficial ownership percentages. The filing states the amendment was triggered by a change in the total number of Green Brick Partners common shares outstanding, not by any purchase or sale of shares by the reporting persons.

The updated share count of 42,432,826, drawn from Green Brick's quarterly report for the quarter ended September 30, 2026, served as the denominator for all percentage calculations disclosed in this amendment.
