Dec 30 (Reuters) - Warner Bros Discovery is expected to reject Paramount ​Skydance's amended $108.4 billion hostile bid, ‌CNBC reported on Tuesday.

The rebuff could brush ‌aside Paramount's effort to shore up deal financing through a $40.4 billion personal guarantee from Oracle co-founder Larry Ellison.

Paramount ⁠and Warner ‌Bros Discovery did not immediately respond to Reuters' requests for ‍comment.

The decision could keep Warner Bros on track to pursue a rival cash-and-stock ​deal with Netflix, underscoring broad ‌concerns over valuation, strategic fit and deal certainty despite Paramount's attempt to sweeten its offer.

Paramount had said Ellison had agreed to personally guarantee equity ⁠financing backing the ​bid, a move aimed ​at easing doubts that had dogged its earlier proposal.

The company ‍also raised ⁠its regulatory reverse termination fee and extended its tender offer deadline, ⁠while the $30-per-share all-cash value remained unchanged.
