NEW YORK (TheStreet) -- Shares of oil company Chesapeake Energy (CHK) - Get Report were falling 2.3% to $16.30 Monday as Brent crude oil prices were falling.

Brent crude oil for April delivery was falling 3.5% to $60.37 a barrel early Monday afternoon. West Texas crude oil for April delivery was gaining 1.4% to $50.44, after falling earlier in the day.

Brent crude oil was falling due to speculation of a nuclear deal that can potentially increase Iran's oil exports, according to Reuters. In a recent statement Iran's Foreign Minister Mohammad Javad Zarif said that a deal regarding Iran's nuclear program could be concluded this week if the U.S. and other Western countries "have sufficient political will and agree to remove sanctions from Tehran," according to the news service.

If the sanctions are lifted Iran could increase its oil exports by up to 1 million barrels a day, analysts told Reuters.

Increasing oil output from Libya and a stronger U.S. dollar were also contributing to lower Brent oil prices earlier in the day.

TheStreet Ratings team rates CHESAPEAKE ENERGY CORP as a Hold with a ratings score of C+. TheStreet Ratings Team has this to say about their recommendation:

"We rate CHESAPEAKE ENERGY CORP (CHK) a HOLD. The primary factors that have impacted our rating are mixed -- some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures and compelling growth in net income. However, as a counter to these strengths, we also find weaknesses including weak operating cash flow and a generally disappointing performance in the stock itself."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

• The revenue growth came in higher than the industry average of 18.7%. Since the same quarter one year prior, revenues rose by 11.2%. Growth in the company's revenue appears to have helped boost the earnings per share.
• The debt-to-equity ratio is somewhat low, currently at 0.66, and is less than that of the industry average, implying that there has been a relatively successful effort in the management of debt levels.
• CHESAPEAKE ENERGY CORP reported significant earnings per share improvement in the most recent quarter compared to the same quarter a year ago. The company has demonstrated a pattern of positive earnings per share growth over the past two years. However, we anticipate underperformance relative to this pattern in the coming year. During the past fiscal year, CHESAPEAKE ENERGY CORP increased its bottom line by earning $1.83 versus $0.68 in the prior year. For the next year, the market is expecting a contraction of 80.0% in earnings ($0.37 versus $1.83).
• CHK's stock share price has done very poorly compared to where it was a year ago: Despite any rallies, the net result is that it is down by 28.99%, which is also worse that the performance of the S&P 500 Index. Investors have so far failed to pay much attention to the earnings improvements the company has managed to achieve over the last quarter. Turning toward the future, the fact that the stock has come down in price over the past year should not necessarily be interpreted as a negative; it could be one of the factors that may help make the stock attractive down the road. Right now, however, we believe that it is too soon to buy.
• Net operating cash flow has decreased to $829.00 million or 21.27% when compared to the same quarter last year. In conjunction, when comparing current results to the industry average, CHESAPEAKE ENERGY CORP has marginally lower results.
