Comcast said on Tuesday that it should be big enough if its $45 billion deal for Time Warner Cable goes through and will not need to make any more major acquisitions, even as merger activity intensifies across the industry.

The company, one of the largest cable and entertainment conglomerates, is awaiting regulatory and shareholder approval for the merger with Time Warner Cable. The deal would unite the two largest cable operators in the United States and give Comcast control of about 30 percent of the cable markets in the nation, and 35.5 percent of the fixed high-speed Internet markets.

In a conference call on Tuesday to discuss its second-quarter earnings, Comcast executives were asked if the company was seeking any more deals to bolster its cable footprint. The executives said they were focused on integrating the two companies and did not expect more transactions.
