American depositary receipts of Alarum Technologies fell after the company said it decided to temporarily pause certain network services, following a recent incident involving its NetNut network.
ADRs tumbled 56%, to $2.80, in premarket trading Monday. Through Friday's close, ADRs have lost roughly a quarter of their value year to date.
The web data collection company before the bell called the pause a precautionary step, enabling a thorough investigation of the incident.
Alarum added it is devoting substantial technical and operational resources to the investigation and recovery process, and that it is working to restore normal operations as soon as possible.
Services will be significantly reduced during the pause, the company said.
