TheStreet Ratings team rates PATTERSON-UTI ENERGY INC as a Buy with a ratings score of B. The team has this to say about their recommendation:
"We rate PATTERSON-UTI ENERGY INC (PTEN) a BUY. This is driven by a few notable strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. 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, attractive valuation levels, solid stock price performance and increase in net income. We feel these strengths outweigh the fact that the company has had somewhat disappointing return on equity."
