DD = Due diligence, It looks like you have done that pretty well.

You might want to throw the ticker DAVE into the comparison hopper, they are another up and coming resteraunt chain.

although if we believe in an truly efficeint market theory, the market will already have reacted to the news that there will be a second offering ;-)

IMHO if this is true buy an index fund and forget about it.

For the class recomondation I would figure out the average price dip that occurs when a new offering hits the street and fudge some sort of price window based on that.

The offering makes the decision a lot more difficult---

I would disagree unless the offering is way over the top. If the company is solid the offering will easily be absorbed over time, it may take a few weeks, months or even a year+. As long as they put this new capital to good use it won't hurt the company or the stock, in fact management is betting its good for the company. Evan a large second offering may be a good thing, it would give them amunition to expand on their own time schedual rather than scrambling to finance the next opportunity that comes along.

As for a personal investment I think you have enough info on whether or not to invest in the co. So the next question is yay or nay; if yay, then you figure what you believe is a fair price:forward P/E, PEG, DCF, historic indicators, whatever your comfortable with. If nay, never look back because it doesn't matter whether it fails or succeeds.

hope that helps
