This filing contains no new pricing, financial, or regulatory information. The stock continues to trade on the original deal thesis. The next material catalyst will be the S-4 filing with full proxy/prospectus, after which Synaptics' shareholder vote and regulatory clearances will be the key milestones. Monitor for any antitrust scrutiny announcements or dissident shareholder activity in the interim.
