**Corporate Update**

December 22, 2025

To Our Valued Clients,

As we head into a new year, we have an exciting milestone to share. Janus Henderson has entered into a definitive agreement to be acquired by Trian and General Catalyst, two growth-oriented investment firms that believe strongly in our business, our people, and our clients. This agreement was negotiated and approved by an independent special committee of our Board of Directors.

We know both Trian and General Catalyst well, and with their partnership, we will be able to further invest in our product offering, client services, technology, and talent to accelerate our growth. We will be even better positioned to deliver differentiated insights, disciplined investments, and world-class service to our clients. Their interest in partnering with us is a strong affirmation of our long-term strategy.

An advantage of going private is that we will be better positioned to build on our momentum and invest even more in our business for the benefit of our clients. Although we are doing well as a public company today, private ownership will give us greater flexibility and patience to make significant long-term investments in our offerings and infrastructure, which will ultimately help us deliver superior returns for our clients.

Both Trian and General Catalyst firmly believe in Janus Henderson's culture and investment approach. They are committed to investing in our platform to achieve continued growth and success.

To that end, we do not expect any impact to our investment funds or our client service as a result of this transaction at this time.

The transaction is expected to close in mid-2026 and is subject to a number of closing conditions, such as shareholder approval and certain client and regulatory approvals. Upon closing, we will no longer be a publicly traded company. We have been public and private at different times in our 91-year history, but our dedication to investing in a brighter future for our clients has never wavered.

If you have questions, please contact your Janus Henderson representative. As always, we thank you for the trust you have placed in Janus Henderson Investors, and we look forward to continuing to partner with you in the new year.

Regards,

**Janus Henderson Investors**
