NEW YORK (TheStreet) -- SunEdison  (SUNE) stock is down 15.87% to $1.75 in pre-market trading on Wednesday, as the renewable energy company will again delay the filing of its annual report. 

The most recent delay comes after SunEdison identified "material weaknesses" in its financial reporting controls, primarily due to "deficient information technology controls in connection with newly implemented systems," according to a statement.

The report's deadline had already been extended to March 15, as the company conducted an internal investigation into the accuracy of the its expected financial position.

The "material weaknesses" have caused additional work to be needed to complete the audit, and SunEdison has consequently missed the filing deadline.

SunEdison added that, so far, its accounting problems have not led to "any material misstatements or restatements" of its previously announced financial statements. 

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

SunEdison'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.
