Sweetgreen drops on weak earnings

Sweetgreen declined 8% after its third-quarter results didn't meet Wall Street's estimates.

The salad chain’s adjusted loss per share came in at 18 cents, missing analysts’ expectations of a 13-cent loss. Sweetgreen posted a 22-cent loss per share for the year-earlier period.

Revenue grew to $173.4 million from $153.4 million but fell short of analysts' expectations of $175.5 million.

Sweetgreen increased the lower end of its 2024 sales outlook, now projecting revenue between $675 million and $680 million, up from the prior minimum of $670 million.

Even allowing for Friday's drop, Sweetgreen stock has more than tripled this year.

Airbnb down on mixed financial results

Airbnb stock lost 8% after its Q3 earnings came in shy of analyst estimates, while its revenue beat.

The home-stay-services provider earned $2.13 a share for the third quarter, a penny shy of the $2.14 expected by analysts surveyed by LSEG. Revenue of $3.73 billion was in line with analysts’ forecast of $3.72 billion.

The company expects fourth-quarter revenue to range between $2.39 billion and $2.44 billion, at the midpoint below analysts' expectation of $2.42 billion.

Airbnb said it was focusing on expanding into underpenetrated markets worldwide, where third-quarter booking growth was double that of core markets.

“We’ll remain focused on accelerating growth while preparing for Airbnb’s next chapter, which will take us beyond accommodations,” Airbnb said. “You’ll see more on this next year.”

Arista Networks falls despite earnings beat

Arista Networks shares fell 7% after the company reported  a thinning margin, despite profits surpassing Wall Street’s expectations.
