After months of tumult in Viacom’s leadership, it came as little surprise that the company had a bad year.

The entertainment company reported on Wednesday a 25 percent plunge in profit and a 6 percent drop in revenue for its fiscal year, which ended Sept. 30.

The results put stark numbers on what was a difficult period for Viacom, which included a fierce fight for control that led to the ousting of the company’s chief executive. Now, the company’s board is considering a proposal from the Redstone family to reunite with CBS.

The ailing 93-year-old media mogul Sumner M. Redstone and his daughter, Shari Redstone, control about 80 percent of the voting shares in Viacom and CBS through National Amusements, the private theater chain company.
