NEW YORK (TheStreet) -- Shares of Whiting Petroleum (WLL) - Get Report  are tumbling 7.48% to $6.80 this afternoon after the company reported 2016 second quarter financial results that were lower than expected after yesterday's closing bell.

The Denver-based oil company reported an adjusted loss of 70 cents per share and revenue of $339.6 million for the quarter. Analysts were looking for the company to report a loss of 30 cents per share and revenue of $403.76 million.

CEO James Volker said the company has been working to strengthen its balance sheet.

"We exchanged an additional $1.1 billion of debt into mandatory convertible debt, bringing our total to $1.6 billion year-to-date. These debt exchanges have effectively reduced Whiting's debt by $810 million as of July 27, 2016 by conversion into stock," he noted.

Additionally, oil prices are falling to three-month lows today, negatively impacting the stock.

Crude oil (WTI) is down 1.74% to $41.19 per barrel and Brent crude is falling 1.79% to $42.69 per barrel.

Oil prices have been falling lately due to mounting concern over a worldwide fuel glut. Genscape added to the concern today, reporting a build of 328,000 barrels at the Cushing, OK delivery hub for U.S. crude futures, CNBC reports.
