Forward-Looking Statements

This communication contains forward-looking information and statements about MUFG, MUS and their businesses after completion of the transaction. Forward-looking statements are statements that are not historical facts. These statements include financial projections and estimates and their underlying assumptions, statements regarding plans, objectives and expectations with respect to future operations, products and services, and statements regarding future performance. Forward-looking statements are generally identified by the words “expect,” “anticipates,” “believes,” “intends,” “estimates” and similar expressions. Although MUFG’s and MUS’s management believe that the expectations reflected in such forward-looking statements are reasonable, investors and holders of MUS securities are cautioned that forward-looking information and statements are subject to various risks and uncertainties, many of which are difficult to predict and generally beyond the control of MUFG and MUS, that could cause actual results and developments to differ materially from those expressed in, or implied or projected by, the forward-looking information and statements. These risks and uncertainties include those discussed or identified in the public filings with the SEC and the local filings made by MUFG and MUS, including those listed under “Cautionary Statement Concerning Forward-Looking Statements” and “Risk Factors” in the prospectus included in the registration statement on Form F-4 that MUFG may file with the U.S. SEC. Other than as required by applicable law, MUFG and MUS do not undertake any obligation to update or revise any forward-looking information or statements.
