Shares of online game developer Zynga rose 12 percent on Tuesday following a Bloomberg report that the company has received takeover interest from rivals.
Zynga's stock climbed 48 cents to $4.36 at the close of trading, and is now up 9 percent for the year. It's the biggest move for Zynga's stock since early 2014.
A company spokesperson declined to comment.
In May, Zynga founder Mark Pincus stepped back from the company for a second time, three years after returning. Pincus relinquished the CEO role in 2016, and said in a blog post five months ago that he was "transitioning to non-executive chairman" and will likely focus his time on investing.
