Comcast beats earnings expectations, gains record internet customers for quarter
Comcast reported Thursday second-quarter results that beat analyst expectations on the top and bottom lines. The company also posted a record of new broadband subscribers for the quarter.

Shares closed up slightly.

Here's what Comcast reported compared to Wall Street's expectations:

Adjusted earnings per share: 84 cents vs. 67 cents expected in a Refinitiv survey of analysts

84 cents vs. 67 cents expected in a Refinitiv survey of analysts Revenue: $28.55 billion vs. $27.18 billion in the Refinitiv survey

$28.55 billion vs. $27.18 billion in the Refinitiv survey High-speed internet customers: 354,000 net adds vs. 270,000 net adds expected in a StreetAccount survey

Comcast said net adds for high-speed internet customers were its highest ever for a second-quarter performance. The company also had its best second quarter for total customer relationships, adding 294,000.

"It was an amazing quarter," CEO Brian Roberts said on CNBC's "TechCheck.," noting that broadband was the "star" business segment in Q2.

The company said NBCUniversal's streaming service, Peacock, has 54 million sign-ups as of this week and more than 20 million monthly active accounts. Comcast, which doesn't split out free and paid users, reported 42 million sign-ups across the U.S. in the first quarter of this year.

NBC Chief Jeff Shell said on the company's call with investors that the direct-to-consumer service is still at the beginning of content roll out. He believes Peacock can achieve sufficient scale without changing course, meaning any mergers and acquisitions likely aren't necessary.

"What we think we can do is look for ways to grow organically, which is what we did this quarter, we've been doing all year, and also if there's partnerships that can accelerate streaming, particularly internationally," Roberts told CNBC.
