Item 8.01 Other Events.

On December 1, 2025, AvalonBay Communities, Inc. (the “Company”) closed the public offering (the “Offering”) of an aggregate of $400,000,000 principal amount of its 4.350% Senior Notes due 2030 (the “Notes”).

The Offering was made pursuant to a prospectus supplement dated November 19, 2025 and a base prospectus dated February 23, 2024 relating to the Company’s registration statement on Form S-3 (File No. 333-277313) (the “Registration Statement”). In connection with the Offering of the Notes, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC, Goldman Sachs & Co. LLC, Mizuho Securities USA LLC and Morgan Stanley & Co. LLC, as representatives of the several underwriters named in the Underwriting Agreement. A copy of the Underwriting Agreement is filed as Exhibit 1.1 to this Current Report on Form 8-K.

The Notes bear interest from December 1, 2025, with interest on the Notes payable semi-annually on June 1 and December 1, beginning on June 1, 2026. The Notes will mature on December 1, 2030 unless the Company redeems them earlier.

The terms of the Notes are governed by an Indenture between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”) (the “Base Indenture”), dated as of February 23, 2024, as supplemented by the Third Supplemental Indenture between the Company and the Trustee, dated as of December 1, 2025 (the “Third Supplemental Indenture”).

The Company estimates that the net proceeds from the sale of the Notes, after deducting the underwriting discount and estimated offering expenses payable by the Company, will be approximately $396.5 million.

The Company intends to use the net proceeds from the Offering for working capital and general corporate purposes, which may include the repurchase of outstanding shares of the Company’s common stock pursuant to the Company’s stock repurchase program, repayment of outstanding indebtedness under the Company’s commercial paper program, which allows the Company to issue, from time to time, unsecured commercial paper notes with varying maturities of less than one year up to a maximum amount outstanding at any one time of $1,000,000,000, land acquisitions, the development and redevelopment of residential communities, the acquisition of communities, funding the Company’s Structured Investment Program investments and the repayment and refinancing of other indebtedness. Pending the application of such net proceeds, the Company may temporarily invest all or a portion of the net proceeds from the Offering in cash or cash equivalents and/or hold such proceeds in accordance with the Company’s internal liquidity policy.

The foregoing description does not purport to be complete and is subject to, and qualified in its entirety by, reference to the full text of the Base Indenture, the Third Supplemental Indenture and the form of the Notes, which are filed as Exhibits 4.1, 4.2 and 4.3 to this Current Report on Form 8-K and are incorporated herein by reference.

In connection with the filing of the Underwriting Agreement, the Company is also filing the opinion and consent of its counsel, Goodwin Procter LLP, regarding the legality of the securities being registered as Exhibits 5.1 and 23.1 hereto, respectively, which are incorporated by reference into the Registration Statement.
