Colorado solar company gets another Nasdaq delisting notice

Real Goods Solar Inc. said it's received another letter from the Nasdaq stock exchange, saying its shares could be delisted from the exchange. On Friday, the Louisville rooftop solar-power installation company said it received a letter saying that it doesn't meet the stock exchange's $2.5 million minimum shareholders' equity requirement. In Real Goods Solar's latest 10-K filing, it listed shareholders' equity of $1 million. The company said it has until the end of May to submit a plan of compliance to the stock exchange. It's not the first time this year that Nasdaq has threatened to delist the company: In January, Real Goods Solar was warned that its share price was trading below $1 for 30 straight days.
