Adjustments

Notes

• Two accounting bases. The fiscal-year figures come from the audited U.S. GAAP consolidated financial statements in Mizuho's Form 20-F for the year ended March 31, 2026 (accession 0001193125-26-283791). The quarterly figures come from Mizuho's "Consolidated Financial Statements for the First Quarter of Fiscal 2026 (Under Japanese GAAP)", furnished on Form 6-K on July 30, 2026 (accession 0001193125-26-324795). Japanese GAAP and U.S. GAAP measure income and the balance sheet differently, so a quarter should be compared only with another quarter, and a fiscal year only with another fiscal year. For example, total assets at March 31, 2026 are ¥294,895,707 million under U.S. GAAP and ¥302,240,042 million under Japanese GAAP.
• Fiscal calendar. Mizuho's fiscal year ends March 31. This record labels each year by the calendar year in which it ends: FY2026 is the year ended March 31, 2026, and Q1 FY2027 is the three months ended June 30, 2026. Mizuho's own Japanese GAAP release calls the year ended March 31, 2026 "Fiscal 2025" and the June 2026 quarter the "First Quarter of Fiscal 2026"; each period's filing_label gives the filing's own name.
• Quarterly line items. Ordinary income, ordinary expenses and ordinary profits are Japanese GAAP captions with no direct U.S. GAAP equivalent. Interest income, interest expense, fee and commission income and expenses, trading income and expenses, general and administrative expenses, taxes and profits are taken from the consolidated statements of income (in millions of yen). Net interest income for each quarter is interest income less interest expense from that statement (¥364,160 million and ¥301,471 million), consistent with the ¥364.1 billion and ¥301.4 billion shown in the release's income analysis. Consolidated gross profits, net fee and commission income, net trading income, net other operating income, net gains related to stocks, equity in income from investments in affiliates, credit-related costs and consolidated net business profits come from the release's consolidated income analysis, which is printed in billions of yen to one decimal place. Credit-related costs are shown as the release prints them: a negative figure is a net cost (¥6.1 billion in the June 2026 quarter) and a positive figure a net reversal (¥11.4 billion in the June 2025 quarter).
• What the quarterly report contains. Mizuho states that it did not prepare a quarterly consolidated statement of cash flows for the three months ended June 30, 2026, so the quarters carry no cash flow figures; the depreciation and goodwill amortization the report discloses instead are shown under supplementary. The report's balance sheet compares June 30, 2026 with March 31, 2026, so the year-ago quarter has no balance sheet and the March 31, 2026 Japanese GAAP balance sheet is carried as its own balance-sheet-only entry. The release states that the quarterly statements were not reviewed by certified public accountants or an audit firm.
• Equity and deposit definitions. Under Japanese GAAP, total_equity is "Total Net Assets", which includes stock acquisition rights and non-controlling interests; total_shareholders_equity excludes accumulated other comprehensive income; and mhfg_shareholders_equity is the "Own Capital" figure the release reports (total net assets less stock acquisition rights and non-controlling interests). Japanese GAAP deposits exclude negotiable certificates of deposit, which are shown separately. Under U.S. GAAP, total_equity includes noncontrolling interests, mhfg_shareholders_equity is total MHFG shareholders' equity, and total_deposits is the sum of domestic and foreign, interest-bearing and noninterest-bearing deposits (the 20-F's selected financial data prints this total; it equals the four deposit lines on the balance sheet).
• Share counts. Fiscal-year weighted-average basic and diluted share counts are from Note 18 of the 20-F, printed in thousands. The quarterly report gives only the average number of shares outstanding used for earnings per share, not a separate diluted count; basic and diluted earnings per share were the same (¥173.53 per share in the June 2026 quarter and ¥115.90 a year earlier). Shares issued and treasury shares are period-end counts as each filing prints them: 2,489,848,594 shares issued at March 31, 2026 and 2,442,831,994 at June 30, 2026, with treasury shares of 51,325,298 and 9,294,931 respectively.
• Capital and return ratios. The fiscal-year capital adequacy and leverage ratios are Mizuho's consolidated ratios calculated under Japanese GAAP and the Financial Services Agency's guidelines, as the 20-F explains; risk-weighted assets are converted at the March 31 rate. Return on average total assets, return on average shareholders' equity and net interest income as a percentage of average interest-earning assets are the 20-F's own U.S. GAAP ratios. The quarterly own capital ratio and non-performing loan ratio are the Japanese GAAP figures the release reports. The June 30, 2026 Common Equity Tier 1, Tier 1 and total capital ratios and risk-weighted assets are Mizuho Financial Group's consolidated international-standard figures from its announcement of its capital ratio as of June 30, 2026, furnished on Form 6-K on August 14, 2026 (accession 0001193125-26-350179); like the fiscal-year ratios, they are calculated under Japanese GAAP and the Financial Services Agency's guidelines, and risk-weighted assets (¥82,213.7 billion) are converted at the June 30, 2026 rate. That announcement does not give a leverage ratio. Its March 31, 2026 column (13.16%, 15.73% and 17.61%, and risk-weighted assets of ¥80,925.3 billion) matches the 20-F.
• Dividends. The fiscal-year figure is the cash dividend per share declared with respect to each fiscal year (¥145.00 per common share for the year ended March 31, 2026, made up of ¥72.50 at the second quarter-end and ¥72.50 at the year-end), stated here per ADS. No dividend is paid for the first quarter. Mizuho's forecast for the year ending March 31, 2027 is ¥150.00 per common share (¥75.00 at the second quarter-end and ¥75.00 at the year-end).
• Earnings estimate. With the first-quarter results, Mizuho raised its Japanese GAAP estimate of profit attributable to owners of parent for the year ending March 31, 2027 from ¥1,300,000 million to ¥1,400,000 million.
• Cash flow presentation. Free cash flow is not presented: for a bank, operating cash flow is driven by trading and lending balances and is not a measure of cash available to shareholders. Purchases of premises and equipment are shown as the 20-F prints them.
• Exchange-rate effect. The yen was much weaker against the dollar in the April-June 2026 quarter (about ¥159.36 per US$1.00 on average) than a year earlier (about ¥144.49), so growth rates measured in dollars are lower than in yen. Profit attributable to owners of parent rose 45.5% in yen (¥422,909 million against ¥290,521 million, as the release reports) but about 32.0% in US dollars.
• Periods not presented. For a first fiscal quarter the year-to-date period is the quarter itself, so no separate year-to-date block is given. No trailing-twelve-month figures are given, because the fiscal-year figures here are U.S. GAAP and the quarters are Japanese GAAP, and combining them would not produce a meaningful total. The FY2024 entry has no balance sheet because the 20-F's balance sheets cover only March 31, 2025 and 2026.

Uncertainties

• The filings state no average exchange rate, so income and cash flow figures are converted at averages of the Federal Reserve's daily noon buying rates, and the June 30, 2026 balance sheet at that day's rate. Mizuho's own translation for these periods, if it published one, could differ slightly.
• These filings do not reconcile the quarter's Japanese GAAP results to U.S. GAAP, so how the quarter would read under the basis used for the fiscal years cannot be determined from them.
• Figures taken from the release's income analysis are printed in billions of yen rounded to one decimal place, and the release states that amounts of less than one million yen are rounded down, so small rounding differences against the statements in millions of yen are expected.
