They had a big backlog this time last year and lost half their money. If the weather is bad again, they could lose the other half. It's a huge risk to loan money to someone who will go bankrupt if it rains. If they run out of money they won't able to complete projects, obviously. This is the exact same issue that RGSE had right before they diluted the stock into oblivion. Go check out what people were saying about their backlog and what it meant in the first half of 2015.
I will say that the new management appears to be much credible on the surface, but so far it's just words.
Sandy, there are lots of bankers with lots of experience in seasonal issues in the Central Valley and lines of credit are common in construction and agriculture. The rainy season ends around end of April in California. SUNW is not debt laden. If they are unable to renew their line of credit I might be worried at that time...
