Empire Bank bought out Citizens National Bank of Springfield in 2010 and almost doubled its presence in Springfield.
Though a part of Central Bancompany (CBCY), its financial is available on FDIC website. Being a formidable competition and having almost identical footprints, it maybe a good gauge for Guaranty's operation and progress.
Q2 results will be my next indicator. There's an ~80% up-side just to trade up to book value. I know you're not Pollyanna, but you might be well served to buy a little stock here. By the time all their preferred stock is paid back and EPS is at $2 I don't think the price will be this good anymore.
There are far, far, fewer x-factors with GFED as compared to a year ago, and the outlook is extremely positive. The risk-reward ratio here makes this look like a steal to any sane investor. There is a small likelihood of any significant dilution. On the other hand, you could reasonably expect to triple your money here in the next couple years.
I've got a hunch Q2 numbers will be, at least, fairly good or they probably wouldn't have bought back $5M in stock.
