Do I have to sell my stock??

Hello all!

A couple years ago, I purchased stock in CHICOS (women’s clothing store) for $2.40 per share. The company was recently acquired by a private firm for 1 Billion dollars and will no longer be a publicly traded company (I think). Overnight, the stock has shot up to over $7.50 per share. Do I need to sell this stock due to the acquisition?
