Sweetgreen shares (SG) fell Friday afternoon after the salad restaurant chain reported a larger-than-expected loss due to rising costs.

Sweetgreen reported a loss of 18 cents per share in the third quarter, while analysts surveyed by Visible Alpha expected a loss of 15 cents per share. Revenue rose 13% year over year to $173.4 million, although that figure also fell short of estimates.

The company said it was facing “higher protein costs and higher payroll expenses associated with increases in prevailing wage rates in many of our markets.”

Sweetgreen also reported that it spent more money to increase its number of locations from 5 to 31. Additionally, general and administrative expenses increased by $800,000 to $36.8 million, primarily in due to the cost of supporting restaurant growth.

Co-founder and CEO Jonathan Neman said the company believes its expanded menu, performance of restaurants opening this year and growth in emerging markets, among other things, will drive “the re-acceleration of our unit growth in 2025 “.

Sweetgreen raised the lower end of its full-year sales outlook, now anticipating a range of $675 million to $680 million, up from $670 million to $680 million previously.

Sweetgreen shares fell more than 5% Friday afternoon, although despite Friday’s loss, their value has more than tripled since the start of the year.
