Forward-Looking Statements
Certain statements in
this communication not based on historical facts are “forward-looking statements” within the meaning of the federal
securities laws, including Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A of the Securities Act
of 1933, as amended. Such forward-looking statements involve known and unknown risks and uncertainties and are based on Janus Henderson’s
and the Trian Parties’ beliefs and assumptions, and information currently available to Janus Henderson and the Trian Parties.
These include statements as to Janus Henderson’s and/or the Trian Parties’ future expectations, beliefs, plans, strategies,
objectives, events, conditions, financial performance, prospects or future events, including with respect to the timing and anticipated
benefits of proposed transaction. 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 Janus Henderson, Trian and their respective management teams, 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. Neither Janus Henderson nor the Trian Parties undertake any obligation to
publicly update or revise these forward-looking statements.
Various risks, uncertainties,
assumptions and factors that could cause actual results, performance, achievements or future results to differ materially from
those expressed by the forward-looking statements included in this communication include, but are not limited to: (1) the impact
of any competing transaction proposal; (2) the ability to obtain the regulatory, shareholder and other approvals required to consummate
the proposed transaction and the timing of the closing of the proposed transaction, including the risks that a condition to closing
would not be satisfied within the expected timeframe or at all or that the closing of the proposed transaction would not occur;
(3) the ability of the Trian Parties to receive the financing needed to consummate the proposed transaction; (4) the outcome of
any legal proceedings that may be instituted against the parties and others related to the merger agreement; (5) that shareholder
litigation in connection with the proposed transaction may affect the timing or occurrence of the proposed transaction or result
in significant costs of defense, indemnification and liability; (6) unanticipated difficulties or expenditures relating to the
proposed transaction, including the impact of the transaction on Janus Henderson’s business; (7) that the proposed transaction
generally may involve unexpected costs, liabilities or delays; (8) that the business of Janus Henderson may suffer as a result
of uncertainty surrounding the proposed transaction or the identity of the purchaser; (9) that Janus Henderson may be adversely
affected by economic, business, and/or competitive factors; and (10) additional factors discussed in Janus Henderson’s Annual
Report on Form 10-K for the year ended December 31, 2025, and in other filings or furnishings made by Janus Henderson with the
SEC from time to time.
