Exhibit 99.1

August 2, 2023

Frequently Asked Questions About the Public Storage UPREIT Reorganization

An umbrella partnership real estate investment trust (UPREIT) structure, which is used by most publicly-traded property REITs, is a holding-company structure in which the publicly-traded REIT (typically formed as a corporation or a Maryland real estate investment trust) holds all of its assets and liabilities in, and conducts all of its business operations through, an operating subsidiary. The publicly-traded REIT generally does not hold any assets other than its direct or indirect interests in the operating subsidiary.    

REITs that have an UPREIT structure may be able to execute acquisition transactions in a manner that provides sellers of properties with tax-deferral opportunities. REITs with UPREIT structures can also offer certain equity compensation programs that are not available to REITs without an UPREIT structure. Public Storage believes aligning its corporate structure with the majority of other property REITs through reorganizing into an UPREIT may enable it to utilize these advantages in the future.

Public Storage has formed a wholly-owned subsidiary (“New PSA”) that will be the parent company following the reorganization. New PSA has formed an indirectly wholly-owned merger subsidiary that will merge with and into Public Storage, with Public Storage surviving the merger as an indirectly wholly-owned subsidiary of the New PSA.

New PSA will then change its name to “Public Storage” and is expected to qualify as a real estate investment trust for federal income tax purposes.
