Judges Alex Lee, Esther Toh, and Susana D’Almada Remedios delivered the guilty verdict on Monday at the West Kowloon Law Courts Building.
Lai, who turned 78 behind bars last week, was found guilty of two counts of conspiring to collude with foreign forces under the Beijing-imposed national security law, and a third count of sedition under colonial-era legislation.
The judges also convicted Lai’s companies – Apple Daily Ltd, Apple Daily Printing Ltd, and AD Internet Ltd – of conspiring to publish seditious publications and to commit foreign collusion.
A four-day mitigation hearing will be held on January 12, the court said.
