WARNER BROS. DISCOVERY, INC.
One corporate group, resolved across 3 separately-registered clusters
in the same GLEIF corporate family (ultimate parent LEI 5493006ZCRFWKF6B1K26). Each
member's own registration independently matches the family, so clusters that merely inherited a carrier's
LEI are excluded.
