• Perseus offers to acquire all PDI shares not owned at 0.136 Perseus shares per PDI share
• Proposed acquisition values PDI at A$2.1 billion, representing a 24.5% premium to last closing price
• PDI Board deems proposal superior to existing Robex Arrangement Agreement

Predictive Discovery Limited (PDI) has received an unsolicited acquisition proposal from Perseus Mining Limited (Perseus) to acquire all outstanding PDI shares not already owned by Perseus. The proposed consideration is 0.136 new ordinary shares of Perseus for each PDI share, valuing each PDI share at A$0.778 based on Perseus' last closing price. This implies a fully-diluted valuation for PDI of approximately A$2.1 billion or US$1.4 billion. The Acquisition Proposal represents premiums of 24.5% to the last closing price of PDI shares and 34.8% to the 10-day volume weighted average price. The proposal is not subject to financing or due diligence conditions. The PDI Board has unanimously determined that the Acquisition Proposal constitutes a 'Superior Proposal' compared to the existing Robex Arrangement Agreement. PDI has notified Robex of the Superior Proposal, triggering a 5-business day matching period during which Robex has the right, but not the obligation, to offer a matching or superior proposal. There is no assurance at this time that the Acquisition Proposal will lead to the termination of the Robex Arrangement Agreement and the execution of a scheme implementation deed with Perseus.
