Reportable Segment Information Derived from Internal Management Reporting Systems, on Basis of Japanese GAAP

The reportable segment information, set forth below, is derived from the internal management reporting systems used by the CODM to assess the performance of the Group’s operating segments. The CODM assesses the performance of each of the operating segments in accordance with internal managerial accounting rules and practices. The CODM’s review of the reported measures of reportable segments includes evaluation of segment profitability and assessment of actual results compared to the budget. These measures are regularly provided to the CODM and are a component of a multifaceted decision-making process regarding segment performance as well as resource and capital allocation. In addition, the format and information are presented primarily on the basis of Japanese GAAP. Therefore, they are not consistent with the consolidated financial statements prepared in accordance with U.S. GAAP. A reconciliation is provided for the total amount of all business segments’ “Net business profits (losses) + Net gains (losses) related to ETFs and others” with income before income tax expense under U.S. GAAP, and the total amount of all business segments’ “Fixed assets” with the total amount of Premises and equipment—net, Goodwill, Intangible assets, and

right-of-use

assets related to operating leases

included

in Other assets reported under U.S. GAAP. “Fixed assets” pertaining to MHBK, MHTB, and MHSC have been allocated to each segment.

Notes:

(1)

Income and expenses of foreign branches of MHBK and foreign subsidiaries with functional currencies other than Japanese Yen have been translated for purposes of segment reporting using the budgeted foreign currency rates. Prior period comparative amounts for such foreign currency income and expenses have been translated using current period budgeted foreign currency rates.

(2)

“Gross profits + Net gains (losses) related to ETFs and others” is reported instead of sales reported by general corporations. Gross profits is defined as the sum of net interest income, fiduciary income, net fee and commission income, net trading income and net other operating income. Net gains (losses) related to ETFs and others consist of net gains (losses) on ETFs held by MHBK and MHTB on their

non-consolidated

basis and net gains (losses) on operating investment securities of MHSC on its consolidated basis. For the fiscal years ended March 31, 2024, 2025 and 2026, net gains (losses) related to ETFs and others amounted to ¥(31.0) billion, ¥45.2 billion and ¥38.3 billion, respectively, of which ¥(37.0) billion, ¥37.0 billion and ¥30.8 billion are included in GMC, respectively.

(3)

“General and administrative expenses” excludes

non-allocated

gains (losses), net, which primarily includes personnel expenses, depreciation expenses, and occupancy expenses. When the CODM assesses segment performance and decides how to allocate resources, these expenses are regularly provided to the CODM in an aggregated form as “General and administrative expenses” and may be used, for example, to evaluate the expense ratio against segment profits and to compare them with the budgeted expense information.

(4)

Net business profits (losses) is used in Japan as a measure of the profitability of core banking operations, and is defined as gross profits (as defined above) less general and administrative expenses (excluding

non-allocated

gains (losses), net) plus equity in earnings (losses) of equity method investees—net less amortization of goodwill and others. Measurement of net business profits (losses) is required for regulatory reporting to the Financial Services Agency of Japan.

(5)

“Fixed assets” is presented based on Japanese GAAP and corresponds to the total amount of the following U.S. GAAP accounts: Premises and equipment—net; Goodwill; Intangible assets; and

right-of-use

assets related to operating leases included in Other assets. The above table does not include other asset amounts because “Fixed assets” is the only balance sheet measure that the CODM uses when evaluating and making decisions pertaining to the operating segments. “Others” in “Fixed assets” includes assets of headquarters that have not been allocated to each segment, “Fixed assets” pertaining to consolidated subsidiaries that are not subject to allocation, consolidating adjustments and others. Certain “Fixed assets” expenses have been allocated to each segment using reasonable allocation criteria.

(6)	“Others” includes the following items:

•

profits and expenses pertaining to consolidated subsidiaries that are not subject to allocation;

•

consolidating adjustments, including elimination of internal transaction between each segment;

•

equity in earnings (losses) of equity method investees—net that are not subject to allocation; and

•

profits and losses pertaining to derivative transactions that reflect the counterparty risk of the individual parties and other factors in determining fair market value.
