1. Organization and Description of Business

​

Sunstone Hotel Investors, Inc. (the “Company”) was incorporated in Maryland on June 28, 2004 in anticipation of an initial public offering of common stock, which was consummated on October 26, 2004. The Company elected to be taxed as a real estate investment trust (“REIT”) for federal income tax purposes, commencing with its taxable year ended on December 31, 2004. The Company, through its 100% controlling interest in Sunstone Hotel Partnership, LLC (the “Operating Partnership”), of which the Company is the sole managing member, and the subsidiaries of the Operating Partnership, including Sunstone Hotel TRS Lessee, Inc. (the “TRS Lessee”) and its subsidiaries, invests in hotels where it can add value through capital investment, hotel repositioning, and asset management. In addition, the Company seeks to capitalize on its portfolio’s embedded value and balance sheet strength to actively recycle past investments into new growth and value creation opportunities in order to deliver strong stockholder returns and superior per share net asset value growth.

​

As a REIT, certain tax laws limit the amount of “non-qualifying” income the Company can earn, including income derived directly from the operation of hotels. The Company leases all of its hotels to its TRS Lessee, which in turn enters into long-term management agreements with third parties to manage the operations of the Company’s hotels, in transactions that are intended to generate qualifying income.

​

As of March 31, 2025, the Company owned 15 hotels.
