Caesars Entertainment says it hopes to complete its $3.7 billion acquisition of the sports betting giant William Hill by next March, after shareholders of the United Kingdom-based company approved the deal Thursday. 

CDC Gaming Reports says the deal was approved with more than 86 percent of votes cast in favor of the transaction. 

The deal also needs approval by the English Court. It was first announced in October. 

Analysts have said the deal could add some $2.5 billion in equity value to Caesars, which currently operates 54 gaming properties in 16 U.S. states.
