NEW YORK (TheStreet) -- SunEdison  (SUNE) stock is surging by 11.11% to $2.60 in mid-morning trading on Thursday, after COO Perez Gundin left the renewable energy company.

Gundin departed the company effective immediately on January 14, SunEdison disclosed in a regulatory filing today, Bloomberg reports.

He had served on the board on SunEdison's TerraForm Power (TERP) yieldco until a November shakeup replaced the yieldco's CEO and caused the resignation of two of its board members, Bloomberg adds.

SunEdison has faced investor scrutiny about its influence over the yieldco. David Tepper's Appaloosa Management is suing SunEdison to prevent TerraForm Power from purchasing Vivint Solar (VSLR) assets following SunEdison's acquisition of the company.

Shares of the SunEdison have tanked roughly 85% this past year as the company has accrued nearly $11.7 billion in debt to become the world's largest clean-energy developer, according to Bloomberg.

Separately, TheStreet Ratings team rates SunEdison as a "sell" with a ratings score of D.

The company's weaknesses include its generally high debt management risk, generally disappointing historical performance in the stock itself and feeble growth in its earnings per share.

Specifically, SunEdison's debt-to-equity ratio is above the industry average, at 8.33, and the company's quick ratio is poor at 0.76, underscoring its inability to avoid short-term cash problems.
