Shares ComcastThe stock dropped Tuesday morning following the announcement by Comcast Cable CEO Dave Watson that the company expected to increase its high-speed Internet customers by 1.3 million this year. This is below the 1.4 million subscriber figure that analysts expected, according to Factset.

On a green day for tech stocks, the stock of this company was more than 5% lower.

This means that Comcast could add 185,000 high-speed Internet customers in its fourth quarter. Its total number is far lower than the 538,000 added last quarter.

Comcast provided guidance early this year on broadband subscribers for the second consecutive time, causing the stock’s dip. Michael Cavanagh (Comcast CEO) had earlier warned in September about the slow pace of broadband additions during the third-quarter.

After the Covid-19 pandemic, investors have been concerned about a slowdown of the broadband sector. This was despite the fact that internet services growth has been fueled by the Covid-19 pandemic. Comcast shares are down 19% from a 52-week peak on September 3, 2021.

Disclosure: Comcast owns NBCUniversal which is CNBC’s parent company.
