Comcast posted higher fourth-quarter revenue on Tuesday, adding new pay-TV and Internet subscribers, as the FCC's vote on net neutrality looms. After the FCC's net neutrality vote on Thursday, consideration of Comcast's $45 billion merger with Time Warner Cable is expected to intensify. Tuna Amobi, senior equity analyst at S&P Capital IQ, says it's become increasingly dicey that the deal will close on schedule. However, Amobi says he believes there's still a chance the deal will go through with added concessions Comcast will be forced to make. Amobi reveals what types of concessions he believes would satisfy antitrust laws and also gives his opinion on shares of Comcast following the company's results.
