Michael Boyd is the founder of medical diagnostics company Sonic Healthcare. The Perth-born entrepreneur’s private investment house, Jardvan, owns investments in Sonic as well as solar panel producer Silex Systems. Boyd founded Sonic in the early 1990s. Jardvan sold stakes in Sonic and Silex this year; 1 million shares in Sonic and 1.87 million shares in Silex. The share price of both companies has declined over the past 12 months, resulting in Boyd’s lower valuation this year. He remains the biggest shareholder of Silex at 17.5 per cent. In 2008, Fulcrum, a company in which Boyd had a big stake, went into liquidation following the collapse of one of its main investments, Advanced Healthcare Group.
