        On April 18, 2014, The Macerich Company (the "Company") made available to its stockholders its 2013 Annual Report, which included a letter to stockholders from Arthur M. Coppola, Chairman of the Board and Chief Executive Officer (the "Letter to Stockholders"). The Letter to Stockholders is attached hereto as Exhibit 99.1.

        The information in this report (including Exhibit 99.1 hereto) is being "furnished" pursuant to Item 7.01 of Form 8-K and shall not be deemed to be "filed" with the Securities and Exchange Commission ("SEC") or incorporated by reference into any other filing with the SEC.

        Forward-Looking Statements.    The Letter to Stockholders contains statements that constitute forward-looking statements which can be identified by the use of words, such as "expects," "anticipates," "assumes," "projects," "estimated" and "scheduled" and similar expressions that do not relate to historical matters. Stockholders are cautioned that any such forward-looking statements are not guarantees of future performance and involve risks, uncertainties and other factors that may cause actual results, performance or achievements of the Company to vary materially from those anticipated, expected or projected. Such factors include, among others, general industry, as well as national, regional and local economic and business conditions, which will, among other things, affect demand for retail space or retail goods, availability and creditworthiness of current and prospective tenants, anchor or tenant bankruptcies, closures, mergers or consolidations, lease rates, terms and payments, interest rate fluctuations, availability, terms and cost of financing and operating expenses; adverse changes in the real estate markets including, among other things, competition from other companies, retail formats and technology, risks of real estate development and redevelopment, acquisitions and dispositions; the liquidity of real estate investments, governmental actions and initiatives (including legislative and regulatory changes); environmental and safety requirements; and terrorist activities or other acts of violence which could adversely affect all of the above factors. The reader is directed to the Company's various filings with the Securities and Exchange Commission, including the Annual Report on Form 10-K for the year ended December 31, 2013, for a discussion of such risks and uncertainties, which discussion is incorporated herein by reference. The Company does not intend, and undertakes no obligation, to update any forward-looking information to reflect events or circumstances after the date of this release or to reflect the occurrence of unanticipated events unless required by law to do so.
