Portillos – currently around 70 stores and wants to expand near 1000 in next 20 years…buy?

Portillos is currently at its lowest point since it IPO. News just broke that they are looking to open 920 stores over the next 20 years. There was a small bump in the stock after hours, maybe people that read the article. Portillos is basically a Chicagoland stock, but with news coming that it's expanding nationwide, perhaps this stock could have some action. 20 years is a long time to hold, but maybe it won't take that long to see some gains. Several websites have it listed as a buy and a few sell. What do you all think? Perhaps it has some more to still go down from where it's at and maybe a buy when plans are more solid of expansion? Or stay away and just put the money in a large ETF where we know it has growth potential?
