Janus Henderson Group plc (NYSE: JHG; "Janus Henderson," or the "Company") announced that Trian Fund Management, L.P. and its affiliated funds ("Trian"), General Catalyst Group Management, LLC and its affiliated funds ("General Catalyst") and the Company have amended their definitive agreement for the pending acquisition of Janus Henderson to increase the price to be paid to Janus Henderson shareholders to $52.00 per share in cash (the "Merger Agreement Amendment"). In addition, if the transaction has not been completed by June 30, 2026 because of a delay in regulatory approvals, Janus Henderson will be permitted to pay a $1.00 per share dividend in each quarter between July 1, 2026 and the closing. The revised agreement provides enhanced value to Janus Henderson shareholders and continues to provide the fastest path to closing and realization of certain, near-term value—in an uncertain geopolitical and macroeconomic environment—at a significant premium to Janus Henderson's unaffected share price. The transaction with Trian and General Catalyst is the only proposal that the Special Committee (the "Special Committee") of the Board of Directors of Janus Henderson (the "Board") has determined to be actionable and able to be completed.
