NEW YORK (TheStreet) -- Shares of Marathon Oil (MRO - Get Report) are falling by 5.04% to $12.15 in midday trading on Wednesday, as the company is expected to post a wider net loss for the 2016 first quarter, compared to the same period last year.

Marathon Oil will announce the financial results from its latest quarter after the market close this afternoon.

The company's net loss is expected to increase while revenue is forecast to drop by 41% year over year.

Analysts surveyed by Thomson Reuters are calling for a loss of 46 cents per share on revenue of $903.27 million.

The company posted a loss of 37 cents per share on revenue of $1.53 billion for the 2015 first quarter.

Also weighing on Marathon Oil's shares this afternoon is the drop in oil prices. The commodity is trading in the red, giving back today's earlier gains as U.S. crude supplies grew to fresh highs last week.

U.S. crude stockpiles increased to 2.8 million barrels last week, according to government data, Reuters reports.

Marathon Oil is a Houston based oil and gas exploration and production company with operations in North America, Europe, and Africa.

Separately, TheStreet Ratings has set a "sell" rating and a score of D on Marathon Oil stock. This is driven by a number of negative factors, which TheStreet Ratings believes should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks it covers.

The company's weaknesses can be seen in multiple areas, such as its deteriorating net income, disappointing return on equity, weak operating cash flow, generally disappointing historical performance in the stock itself and feeble growth in its earnings per share.

TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author.
