Summary of Claim

The class action alleges contraventions of the ASIC Act, Corporations Act and the Australian Consumer Law in seeking to establish that Sirtex engaged in misleading or deceptive conduct and/or breached its continuous disclosure obligations.

The primary disclosure issue relates to Sirtex’s dose sales growth guidance for the SIR Spheres and it’s disclosure to the market that the 1H17 dose sales were substantially less than previously forecast. After Sirtex was prompted by the ASX, it made an announcement on 9 December 2016 that the dose sales growth rate would be 4% to 6% rather than the 15.7% previously forecast. Upon the announcement, the Sirtex share price fell by 37%.

A further disclosure issue is the nature of share trades undertaken by then-CEO, Gilman Wong. Mr Wong sold 74,968 Sirtex shares on 26 October 2016 in order to, in the company’s words, ‘cover the tax incurred in relation to the recently vested tranche of rights.’ When Sirtex subsequently announced on 16 December 2016 that they had formally engaged its legal advisors, Watson Mangioni, to investigate Mr Wong’s trading activities, the Sirtex share price suffered a two day price drop of 9%. Mr Wong’s employment with Sirtex was subsequently terminated on 13 January 2017.
