Shares in LeapFrog Enterprises Inc. have jumped by around 70% today after Hong Kong-based VTech Holdings Ltd said it would buy the US toymaker for about $72 million or $1 per share, a 78.50% premium to LeapFrog's Thursday's close of $0.56. At time of writing, the shares are trading just under the bid price at $0.96.
Today's bid will be tough to swallow for LeapFrog's long-term shareholders. Indeed, over the past 12 months, the company's shares have lost more than two-thirds of their value. This time last year, LeapFrog's shares were trading at $2, today's offer is 50% below that level. Since July 2013, LeapFrog's shares have lost 95% of their value.
