Yingli Plummets After It Says It Has "Substantial Doubt" About Its Future

The company cited recurring losses, negative working capital, net cash outflows and doubts related to its ability to service debt as reasons for the uncertainty. Yingli hasn?t posted a quarterly profit since Q2 2011 and remains one of the most indebted firms in the solar industry. The remarks cast a shadow on the company's future at a time when the outlook for the broader solar sector remains largely positive, with global installation growth expected to come in at over 20% for 2015.
