03:34 PM EST, 12/09/2024 (MT Newswires) -- T-Mobile US ( TMUS ) Chief Executive Mike Sievert said Monday that while the company still feels confident about meeting its guidance, investors should watch out for risks that could weigh Q4 results.

"Investors should be cautious because there's a lot of risk in the back half," Sievert said, speaking at a UBS investor conference, according to a transcript available on FactSet.

Sievert also said that people might get worried about a "slowdown" sequentially, but T-Mobile had a good Q3 that saw a "decade-long record" in adding new mobile customers. Most of the quarter is still remaining and even though the start was not good, the company is still confident about quarterly results.

T-Mobile shares were down more than 6% in recent trading.
