CITIGROUP INC 8-K

What Happened

• Citigroup Inc. filed a Current Report on Form 8‑K on April 3, 2026, furnishing Exhibit 99.1 (Historical Quarterly Financial Data Supplement) to support comparability with its Q1 2026 earnings materials (to be issued April 14, 2026). The supplement covers five years of quarterly and annual data through December 31, 2025 and incorporates reporting changes effective in the first quarter of 2026.
• The filing reflects two principal changes: (1) Citi moved its Retail Banking business from U.S. Personal Banking (USPB) into Wealth and reorganized the remaining USPB activities into a new U.S. Consumer Cards segment; and (2) Citi updated its tangible common equity (TCE) allocation methodology among Services, Markets and Banking to better align capital with shared corporate-lending economics. Prior periods were recast at the segment level; consolidated results and consolidated TCE are unchanged. The company referenced additional detail in its 2025 Form 10‑K filed February 20, 2026.

Key Details

• Exhibit furnished: Historical Quarterly Financial Data Supplement for five-year quarterly and annual periods ended Dec. 31, 2025 (Exhibit 99.1).
• Retail Banking: financial results, balance sheet and TCE moved into the Wealth segment.
• New segment: remaining USPB businesses were integrated into a new U.S. Consumer Cards segment.
• TCE methodology update: increased allocated TCE and reported revenues for Services and Markets; decreased allocated TCE and reported revenues for Banking; eliminated a prior corporate-lending revenue share reflected in “All Other.” Prior period segment results and TCE allocations were recast; consolidated totals unchanged.

Why It Matters

• For investors, the change alters segment-level comparability: segment revenues, allocated capital (TCE), and related metrics (e.g., return on allocated capital) will differ under the new presentation and should be compared using the recast historical supplement.
• Consolidated Citigroup financial results and total TCE are not affected, so company-wide performance comparisons remain consistent.
• Review the furnished Historical Quarterly Financial Data Supplement and the Q1 2026 earnings materials (April 14, 2026) — and the 2025 Form 10‑K — to understand the impact on segment trends, capital allocation and reported segment revenues.
• Note: the exhibit was “furnished” (not “filed”) under the Securities Exchange Act.
