Letter from the CEO of Janus Henderson Group plc to its employees, dated December 22, 2025.

Hi everyone,

I hope you're getting ready for a restful holiday period very soon. Today, I am pleased to share that Janus Henderson is going private again. We have reached an agreement to be acquired by Trian and General Catalyst, two growth-oriented investment firms that are energized by what the firm has accomplished so far, recognize the significant potential of our business, and are committed to supporting us going forward. This agreement was negotiated and approved by an independent special committee of our Board of Directors.

This announcement marks an important milestone for Janus Henderson. As longtime shareholders and Board members with expertise in the asset management industry, Trian is one of our biggest supporters and has seen firsthand the value we bring to our clients. General Catalyst is a growth-oriented investment firm with experience leveraging technology and AI to help businesses remove constraints to reach their full potential. In partnership with them both, we will be able to further invest in our product offering, client services, technology, and talent to accelerate our growth and build for the future.

![](tm2534023d3_defa14aimg02.jpg)

I want to emphasize that this transaction is a testament to every one of you who have executed on our strategy to Protect & Grow our core, Amplify our strengths, and Diversify where we have the right, putting our clients first—always. Trian's and General Catalyst's interest in partnering with us is a strong affirmation of our long-term strategy and the talent behind it. Thanks to you—individually and collectively—we are seeing tangible momentum in the business, and going forward we should be even better positioned to deliver on our mission of differentiated insights, disciplined investments, and world-class service to our clients.

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. As we move through the approval process, it's important that we stay focused on what we do best—delivering for our clients, together. We know you will have questions as we move forward, and we are committed to ensuring that employees are kept informed. I want you to know that management and our new owners have discussed and are committed to employee topics like our work-from-home policy, compensation, and benefits, etc. We will have a Town Hall after the holidays, where we will provide additional thoughts about our exciting future. I am also happy for you to reach out to me with any suggestions, topics, or questions in advance at <u>CEOideas</u>.

Once the transaction closes, we will no longer be a publicly traded company. An advantage of going private is that we no longer will have to operate within the framework of public market expectations and volatility which we believe will better position us to build on our momentum and invest even more in our business for the long term. We'll be able to enhance the client experience and pursue innovation across our product offering and technology without the short-term pressures of public capital market volatility or expectations. In summary, 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 and growth for the firm.

As I've said before, during our 91-year history, Janus Henderson has been public and private at different times, and we have never lost focus on investing in a brighter future together for our clients and employees.

In the note I sent last week, I said how proud I am of the work we have accomplished together in 2025, and I am confident we will carry this success into 2026 as well. Again, I hope you take some time over the holidays to recharge and spend time with your families and friends.

All my best,

Ali

Certain statements in this communication not based on historical facts are "forward-looking statements" within the meaning of the federal securities laws. Such forward-looking statements involve known and unknown risks and uncertainties that are difficult to predict and could cause our actual results, performance or achievements to differ materially from those discussed. These include statements as to our future expectations, beliefs, plans, strategies, objectives, events, conditions, financial performance, prospects or future events, including with respect to the timing and anticipated benefits of pending and recently completed transactions and strategic partnerships, and expectations regarding opportunities that align with our strategy. In some cases, forward-looking statements can be identified by the use of words such as "may," "could," "expect," "intend," "plan," "seek," "anticipate," "believe," "estimate," "predict," "potential," "continue," "likely," "will," "would," and similar words and phrases. Forward-looking statements are necessarily based on estimates and assumptions that, while considered reasonable by us and our management, are inherently uncertain. Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of the date they are made and are not guarantees of future performance. We do not undertake any obligation to publicly update or revise these forward-looking statements.
