Internal Memo
Message from Chief Administrative Officer & General Counsel
Subject: Vote Now
Hi everyone,
You may have seen the news from Victory Capital today. While the Special Committee will need to review today’s revised proposal, this does not change the fact that the Trian and General Catalyst take-private agreement is in full force and effect as the only board-approved proposal and that we are still soliciting votes for that transaction. As mentioned in Ali’s note last week, for those of you who are also JHG stockholders and Janus Henderson fund shareholders, a great way to express your views is by voting, as you all represent a meaningful percentage of shareholder votes.
Your vote matters, and the voting process continues even as the Special Committee takes the time it needs to review today’s revised proposal from Victory Capital. Any such consents will not have any effect on any other potential transaction.
Essential to closing the Trian/General Catalyst transaction are two different solicitations or voting processes, both of which are already underway. As part of this process, you may be asked to vote either as:
1) A shareholder of Janus Henderson common stock or;
2) A shareholder of one or more of Janus Henderson’s U.S. mutual funds or ETFs.
The process is now open, and we ask you to please vote as soon as possible ahead of the Special Meetings of Shareholders.
To help make voting quick and easy, we’ve outlined below all you need to know to cast your vote(s). The sooner you vote, the faster we can advance our path to closing.
Solicitation 1: JHG Stock Shareholder Vote
Our Board of Directors strongly recommends shareholders vote FOR the take-private transaction with Trian and General Catalyst, which provides immediate and certain value through an all-cash payment of $49 per share.
If you elected to receive proxy materials electronically, you will or may have already received an email from either Fidelity, id@proxyvote, Computershare or EquatePlus with voting instructions and a link to vote your shares. Please follow those instructions to vote as soon as possible.

Solicitation 2: U.S. Mutual Fund & ETF Shareholder Vote
Your vote is needed to enable Janus Henderson to continue to serve as your investment adviser for your funds once the take-private transaction with Trian and General Catalyst closes. That is because the take-private transaction represents a change of ownership even though fund management will remain the same after closing.
The Board of Trustees recommends that fund shareholders vote FOR approval of the new investment advisory agreement between your mutual fund and/or ETF and Janus Henderson.
