Fitbit shares fell as much as 17% on Thursday after the maker of smart wearables forecast second-quarter revenues lower than analysts expected.
Earnings released Wednesday topped expectations, but guidance for the current quarter missed even the lowest forecast.
The company reported adjusted earnings per share (EPS) of $0.10, beating the forecast for $0.02, according to Bloomberg. Revenues totaled $505.4 million, also topping the estimate for $443.3 million.
But guidance for the second quarter was light, at a range of $0.08-$0.11, versus $0.26 expected.
Fitbit said it sold 4.8 million devices during the first quarter.
Some analysts had raised questions about the company's ability to compete effectively with rivals like Apple. But Fitbit stands to benefit from a projected surge in wearable-device shipments over the next few years.
According to IDC, Fitbit moved the most devices globally in 2015 and had the largest market share.
Fitbit's guidance for profits this year also beat expectations. It sees full-year adjusted EPS at $1.12-$1.24, up from an earlier projection.
"Based on the first quarter’s performance and momentum, we are confident about the remainder of the year, which is reflected in our increased guidance," said CEO James Park.
Fitbit sees full-year revenues of $2.5 billion to $2.6 billion. Its second-quarter revenue forecast was better than expected, at a range of $565 million to $585 million, versus $531.3 million expected.
The stock has lost half its value since the company's initial public offering in June 2015.
