AIG On September 24, 2026, American International Group, Inc. (“AIG”) closed the sale of €625,000,000 aggregate principal amount of its 4.250% Notes Due 2031 (the “2031 Notes”), alongside €500,000,000 aggregate principal amount of its 4.750% Notes Due 2036 (the “2036 Notes” and, together with the 2031 Notes, the “Notes”). AIG disclosed the closing in a FORM 8-K CURRENT REPORT Pursuant to Section 13 or 15(d) of The Securities Exchange Act of 1934 filed with the U.S. Securities and Exchange Commission. Together, the two tranches combine the principal amounts AIG disclosed separately for each series in the filing.
Two tranches, two maturities
The offering was structured as two separate series recorded in a single filing. The filing states: “On September 24, 2026, American International Group, Inc. (‘AIG’) closed the sale of €625,000,000 aggregate principal amount of its 4.250% Notes Due 2031 (the ‘2031 Notes’)”. The same document separately records that €500,000,000 aggregate principal amount of its 4.750% Notes Due 2036 (the “2036 Notes” and, together with the 2031 Notes, the “Notes”).
Each series carries its own euro-denominated principal amount, fixed coupon and stated maturity year. The two coupons on record are 4.250% for the 2031 Notes and 4.750% for the 2036 Notes. The filing treats the 2031 Notes and the 2036 Notes as distinct instruments even as it groups both under the collective term used throughout the document. No other tranche, currency or maturity is referenced in the filing beyond the two series covered here.
Underwriters named in the agreement
The filing identifies the underwriting arrangement behind the offering, covering both series under a single agreement rather than two separate arrangements. Underwriting Agreement, dated September 15, 2026, between AIG and Deutsche Bank AG, London Branch, J.P. Morgan Securities plc, BNP PARIBAS and Citigroup Global Markets Limited, as representatives of the several underwriters named in Schedule I thereto, relating to the Notes.
The agreement names four banks as representatives of a wider group of underwriters listed separately in a schedule to the agreement. It carries the date dated September 15, 2026, nine days before the notes closed on September 24, 2026. The filing does not itself enumerate the remaining names in that schedule. In a separate development, InsuraBeat has covered AIG’s completed Corebridge separation.
Trustee and indenture filings
Each series is also tied to its own supplemental indenture with the trustee named in the filing. Forty-Eighth Supplemental Indenture, dated September 24, 2026, between AIG and The Bank of New York Mellon, as Trustee, relating to the 2031 Notes covers the first series. Forty-Ninth Supplemental Indenture, dated September 24, 2026, between AIG and The Bank of New York Mellon, as Trustee, relating to the 2036 Notes covers the second series.
The trustee is named in both instruments as The Bank of New York Mellon, as Trustee, appearing separately in the Forty-Eighth Supplemental Indenture and again in the Forty-Ninth Supplemental Indenture rather than under a single combined indenture covering both series. In unrelated recent coverage, InsuraBeat has reported on Aon’s notes pricing tied to its USI acquisition financing.
Legal opinion and filing mechanics
A legal opinion accompanies the filing alongside the underwriting and trustee documents already described. Opinion of Sullivan & Cromwell LLP, dated September 24, 2026, as to the validity of the Notes. The opinion addresses the validity of the Notes as the term is defined collectively in the filing, covering both series together under that single definition.
The filing also records a related consent tied to that opinion. 23.1 Consent of Sullivan & Cromwell LLP (included in Exhibit 5.1). The consent is incorporated by reference into the exhibit that carries the opinion itself, rather than standing as a separate freestanding document. Its own numbering, 23.1, places it later in the exhibit list than the 5.1 numbering carried by the opinion it supports. The filing as a whole was submitted as a CURRENT REPORT Pursuant to Section 13 or 15(d) of The Securities Exchange Act of 1934.
Filing details on record
The Form 8-K also carries the standard identifying details found on an SEC cover page. The filing’s cover page lists the entry “Common Stock, Par Value $2.50 Per Share AIG New York Stock Exchange,” naming the exchange as New York Stock Exchange. The same cover page lists Delaware 1-8787 13-2592361, with the commission file number appearing as 1-8787 and the employer identification number as 13-2592361. The address on file is given as 1271 Avenue of the Americas New York, New York 10020.
The filing’s signature block reads: By: /s/ Christopher Arana Name: Christopher Arana Title: Deputy Corporate Secretary. None of these identifying details concern the pricing terms of the Notes; they appear on the filing’s cover and signature pages alongside the underwriting agreement, the two indentures, the opinion and the consent, all part of the same Form 8-K submission.
Taken together, the filing’s exhibits set out the offering’s underwriting terms, its two supplemental indentures, the legal opinion and its consent, alongside the cover-page identifiers now on record with the SEC for this transaction. In a separate development, AIG’s board of directors carried out a leadership transition that InsuraBeat covered in a dedicated report. AIG’s underwriting income figures for the most recent quarter were reported separately by InsuraBeat. Neither item is addressed in the Form 8-K covering the notes offering.
