NEW YORK (TheStreet) -- Shares of AT&T (T) - Get Report were slumping in pre-market trading on Wednesday after UBS lowered its rating on the stock to "neutral" from "buy."

The firm reduced its price target to $43 from $46 on shares of the Dallas-based wireless carrier. UBS also cut earnings estimates by 3%.

UBS cited expectations for diminished earnings growth and heightened competition in the wireless market, according to CNBC.

Separately, TheStreet Ratings team rates the stock as a "buy" with a ratings score of A+.

AT&T's strengths such as its robust revenue growth, increase in net income, good cash flow from operations, solid stock price performance and expanding profit margins outweigh the fact that the company has had generally high debt management risk by most measures that we evaluated.
