Paramount Global shareholder Mario Gabelli has filed a formal complaint in the Delaware Court of Chancery to compel the media giant to comply with his books and records request related to its pending $8 billion merger with Skydance Media.

Money manager Mario Gabelli is asking a judge to make the film and TV company Paramount Global hand over files about its merger with Skydance Media so investors can tell what controlling stockholder Shari Redstone is getting in the deal and whether it’s fair.

Gabelli, whose funds hold approximately 12% of Paramount's voting shares, has claimed that the company has declined to provide records that would reveal if the profits Redstone is making from the sale of her National Amusements Inc. (NAI), are unfairly disadvantaging Paramount's minority shareholders, based on Delaware corporate law, it added.

For the people running Skydance Media, a “quick and clean” regulatory approval to buy Paramount Global has been replaced by “long and slow” — and that’s if they’re lucky, On The Money has learned. The long-awaited merger’s final consummation is likely to remain in regulatory purgatory for the foreseeable future,
