Brian L. Roberts, Comcast’s chief executive, said in the call that the company was disappointed about the collapse of the deal but had moved on. He said that Comcast’s top priorities now were to advance its existing business and improve its poorly rated customer service.

Some analysts expect the company to start pursuing deals to enlarge its international footprint or expand into the wireless business, but Comcast executives did not reveal any new proposals. Mr. Roberts said that it did not have plans to swap subscribers with other cable operators or increase its footprint in the United States.

“In terms of other things that could come along, I believe we have a very special company and so many different businesses,” Mr. Roberts said. “We’re always open-minded. We’ve always been, however, I think extremely disciplined and focused on building shareholder value. And right now, we’re back to work and there’s nothing that I could think of that we don’t have on our plate that I’m excited about.”

Comcast reported a 10 percent increase in earnings in the first quarter, largely because of growth in its high-speed Internet business.

Total revenue inched up 2.6 percent to $17.9 billion during the quarter compared with the period last year, the company said. Without counting sales tied to the 2015 Super Bowl and the 2014 Olympics — both of which were broadcast on NBC, which Comcast owns — revenue increased 7.2 percent during the period.
