Lego faces three main threats to its business: losing licensing rights from Disney, losing its brick trademark, and increased competition from Hasbro. To address these threats, Lego should negotiate with Disney to retain licensing rights, pursue new licensing deals with properties like DC comics, expand into emerging markets like China and India, broaden its customer base, and invest in new product innovations like high-tech bricks. In the long term, Lego needs to implement strategies to maintain its leading position in the brick toy market and continue growing its profits.
