Tabcorp Holdings Limited (ASX:TAH) is understood to have opted to move forward with a strategic review to consider a demerger of its wagering and media unit, with an announcement on the transaction due as early as March 12, 2021. The $10 billion betting company is understood to have received at least three bids for the business from the start of the year. The market expected Tabcorp to make an announcement on its plans for the division when it delivered its half-year results last month. However, while delivering results, Tabcorp said its board would take time to consider relevant issues and strategic options that arise in respect of the proposals. Shareholders have been lobbying Tabcorp to carry out a demerger of the business since last year, after expressing frustration over the company's performance since it led an $11 billion demerger with Tatts in 2017.
