CITIGROUP INC 8-K

What Happened

• Citigroup Inc. filed a Current Report on Form 8-K on January 12, 2026 disclosing that it attached multiple supplemental indentures dated January 9, 2026 between Citigroup (and, in one case, Citigroup Global Markets Holdings Inc.) and The Bank of New York Mellon, as trustee.
• The supplemental indentures relate to several underlying indentures dated March 15, 1987; October 7, 1996; July 23, 2004; June 1, 2005; and March 8, 2016. The filing also includes a list of Citigroup securities registered under Section 12(b) as of the filing date and the Inline XBRL cover page.

Key Details

• Effective date of the supplemental indentures: January 9, 2026.
• Trustee for all listed supplemental indentures: The Bank of New York Mellon.
• Parties: Citigroup Inc. is party to all; Citigroup Global Markets Holdings Inc. is party to the supplemental indenture tied to the March 8, 2016 indenture.
• Exhibits filed include five supplemental indentures (Exhibits 4.1–4.5), a securities registration list (Exhibit 99.1), and the Inline XBRL cover page (Exhibit 104).

Why It Matters

• Supplemental indentures modify or supplement the terms of existing debt agreements; investors in Citigroup bonds or other debt instruments should review the filed exhibits to understand any changes to covenants, payment terms, or other rights.
• The 8-K itself contains the exhibits but does not summarize amendments in narrative form; retail investors needing details should read the specific supplemental indentures and the securities registration list attached to the filing.
