Item 8.01. Other Events.

On December 3, 2025, Essex Property Trust, Inc. (the “Company”) and Essex Portfolio, L.P. (the “Operating Partnership”) entered into an underwriting agreement (the “Underwriting Agreement”) with Wells Fargo Securities, LLC and J.P. Morgan Securities LLC, as representatives of the several underwriters named therein (the “Underwriters”), in connection with the public offering by the Operating Partnership of $350.0 million aggregate principal amount of the Operating Partnership’s 4.875% senior notes due 2036 (the “Notes”). The Notes will be fully and unconditionally guaranteed by the Company. The press release announcing the pricing of the Notes is filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The Operating Partnership intends to use the net proceeds of this offering to repay upcoming debt maturities, including to fund a portion of the repayment of the Operating Partnership’s $450.0 million aggregate principal amount outstanding of 3.375% senior notes due April 2026, and for other general corporate and working capital purposes, which may include the funding of potential acquisition opportunities. Pending application of the net proceeds from the offering for the foregoing purposes, such proceeds initially may be used to fund the repayment of outstanding indebtedness under the Operating Partnership’s commercial paper program and unsecured credit facilities and/or invested in short-term securities.

Neither the press release nor this Current Report on Form 8-K constitutes an offer to sell or the solicitation of an offer to buy any securities nor will there be any sale of these securities in any jurisdiction in which, or to any person to whom, such offer, solicitation or sale would be unlawful.

The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by the full text of the Underwriting Agreement, which is being filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference.
