The group said it had experienced unauthorised access to IT systems in two of its divisions — feeds and fuels — at group level.
There was no unauthorised access at the group’s food division.
NWF has engaged external specialists and taken precautions with its IT infrastructure, including taking systems offline while it investigates the incident.
It is also looking into if it can recover any compromised data and whether there were any effects on how its systems operate.
It said it is using alternative systems to fulfil and deliver orders in the feeds and fuels divisions, and that the businesses remain operational.
The company said: “In light of the complex and evolving nature of this situation, the board has requested that trading in the Company's ordinary shares be suspended until it is in a position to provide more definitive information.”
Once trading in a security is suspended, shares cannot trade until the suspension is lifted or lapses.
According to FT data, its shareholders include Birta Pension Fund, Festa Pension Fund and Canaccord Genuity Wealth Ltd.
