Salomon Smith Barney Inc. analyst Niraj Gupta reiterated his "buy" rating on Mediacom Communications Corp., citing the company's strong balance sheet and its position as one of the few remaining buyers of midmarket systems. In his report, Gupta said Mediacom expects 2001 revenue and cash flow to be $837 million and $333 million, respectively. The MSO also stands to benefit from potential systems sales emerging from the merger of AT&T Broadband and Comcast Corp., because of Mediacom's focus on non-metropolitan systems. Gupta's 12-month price target on the stock is $21, which represents a 15 percent premium from current levels. Mediacom closed at $17.33 on Jan. 9, down 88 cents.
