GoPro Inc (GPRO.O) forecast current-quarter revenue well below analysts’ estimates on weak demand for its wearable cameras and the company named Brian McGee as its new chief financial officer.

GoPro said McGee, who joined the company from Qualcomm Inc (QCOM.O) in 2015, would succeed Jack Lazar as CFO on March 11.

The camera maker’s shares fell 10 percent in extended trading on Wednesday.

Demand for GoPro’s helmet- and body-mounted cameras has been declining as rivals such as China’s Xiaomi XTC.UL offer cheaper products and smartphone cameras turn increasingly advanced.

“…We recognize the need to develop software solutions that make it easier for our customers to offload, access and edit their GoPro content,” Chief Executive Nicholas Woodman said in a statement.

GoPro forecast revenue of $160 million to $180 million for the first quarter ending March. Analysts on average were expecting $298 million, according to Thomson Reuters I/B/E/S.

The company’s revenue fell 31 percent to $436.6 million in the fourth quarter ended Dec. 31, missing the average analyst estimate of $496.1 million.

GoPro, which had already released its quarterly numbers last month, reported an adjusted loss of 8 cents per share. Analysts had expected the company to break even on a per-share basis.
