On November 27, 2024, The Macerich Company (the "Company") completed the issuance and sale of 23,000,000 shares (the "Shares") of the Company's common stock, par value $0.01 per share (the "Common Stock"), pursuant to an underwriting agreement, dated as of November 25, 2024 (the "Underwriting Agreement"), by and among the Company and Goldman Sachs & Co. LLC, as representative of the several underwriters named on Schedule I thereto (the "Underwriters"). The Company granted the Underwriters a 30-dayoption to purchase up to an additional 3,000,000 shares of Common Stock, which was exercised in full. The public offering price of the Shares is $19.75 per share.

The offer and sale of the Shares were registered with the Securities and Exchange Commission (the "Commission") pursuant to a registration statement on Form S-3(File No. 333-273707) (the "Registration Statement") under the Securities Act of 1933, as amended, which became effective upon filing with the Commission on August 4, 2023.

The Company will contribute the net proceeds from the offering, including proceeds from the exercise by the Underwriters of their option to purchase additional shares, to The Macerich Partnership, L.P. (the "Operating Partnership") in exchange for securities of the Operating Partnership that have economic interests substantially similar to those of the Common Stock. The Operating Partnership intends to use the net proceeds from the offering, together with $39.0 million in cash on hand, including net proceeds from sales under the Company's "at the market" offering program, to repay the $478.0 million mortgage loan secured by the Company's Washington Square property. Pending such use, the Operating Partnership may invest the net proceeds in short-term, interest-bearing deposit accounts.

The Underwriting Agreement contains customary representations, warranties and covenants by the Company. It also provides for customary indemnification by the Company for losses or damages arising out of or in connection with the sale of the Shares.

The foregoing description of the Underwriting Agreement does not purport to be complete and is subject to, and qualified in its entirety by, reference to the Underwriting Agreement, a copy of which is filed as Exhibit 1.1 hereto and is incorporated herein by reference.

A copy of the legal opinion of the Company's counsel, Venable LLP, relating to the legality of the Shares is attached hereto as Exhibit 5.1 and is incorporated herein by reference and into the Registration Statement.
