Kirkland & Ellis advised an investor group (including General Catalyst and Trian Fund Management) on a definitive agreement to acquire Janus Henderson Group plc (NYSE: JHG) for $7.4 billion.
Under the agreement, shareholders not already owned or controlled by Trian will receive $49.00 per share in cash; the deal was announced December 22, 2025 and is expected to close in mid-2026, subject to customary conditions (including regulatory approvals, client consents, and shareholder approval).
The matter was handled by a cross-practice Kirkland team spanning corporate, capital markets, debt finance, tax, and investment funds.
