Mesoblast Shareholder Class Action

Mesoblast Shareholder Class Action

Omni Bridgeway is co-funding a shareholder class action against Mesoblast Limited (ASX:MSB) (Mesoblast) on behalf of persons (Group Members) who acquired Mesoblast shares or related securities between 22 February 2018 and 17 December 2020 inclusive. The Full Group Member definition is set out below.  

On 19 October 2022, the Federal Court ordered that two class actions against Mesoblast be consolidated into one set of consolidated proceedings known as Paul Tibor Horsky and Oil Surveillance Australia Pty Ltd ATF D.A Lynch Superfund v Mesoblast Limited (ACN 109 431 870) (VID268/2022) (Consolidated Class Action).

Omni Bridgeway is co-funding Phi Finney McDonald and William Roberts (the Lawyers) as joint solicitors on the record for the Consolidated Class Action alongside ICP Funding Pty Ltd and Investor Claim Partners Pty Ltd (together, ICP).


The Consolidated Class Action concerns Mesoblast’s public statements regarding potential applications of it's product known as Remestemcel-L (R-L), which has been developed to treat inflammatory diseases.

The Consolidated Class Action concerns the following applications of R-L:

  1. first, in respect of the treatment of paediatric patients suffering from steroid refractory acute Graft versus Host Disease (SR-aGVHD application); and
  2. secondly, in respect of patients suffering from acute respiratory distress syndrome (ARDS) caused by COVID-19 (COVID-19 application).

Causes of Action

Broadly, the Consolidated Class Action alleges that Mesoblast contravened its continuous disclosure obligations and engaged in misleading or deceptive conduct throughout the Claim Period in relation to both the SR-aGVHD application and COVID-19 application of R-L.

Participants in the class action may be entitled to compensation for losses arising out of Mesoblast’s alleged breaches of its continuous disclosure obligations and/or by Mesoblast engaging in misleading and deceptive conduct.


Pursuant to the Consolidation Order, Omni Bridgeway and ICP are now co-funding the Consolidated Proceedings on a 50:50 basis, on Joint Funding Terms agreed between Omni Bridgeway and ICP, which are set out in Schedule 4 of the Funding Agreement and take priority over the Funding Agreement to the extent of any inconsistency while they remain in effect.  

Will it cost anything to participate in the class action?

The Lawyers will conduct the Litigation on a No Win-No Fee basis in accordance with the Joint Funding Terms, the Funders will provide funding on behalf of the Claimant, in respect of Legal Costs incurred by the Lawyers.

In return, the Funders will be entitled to a share of any amount awarded or settled in relation to the Consolidated Class Action. The amounts payable to the Funders and the lawyers cannot exceed the amount recovered as part of the Consolidated Class Action.

There are no ‘out of pocket’ costs for class members to pay. Group members do not have to pay anything in the event that the consolidated class action is unsuccessful, as Omni Bridgeway and ICP agree to pay any legal costs that might be awarded to Mesoblast or any other respondents.
