1. ORGANIZATION OF THE PARENT COMPANY AND THE OPERATING PARTNERSHIP

Brandywine Realty Trust (the Parent “Company”) is a self-administered and self-managed real estate investment trust (“REIT”) engaged in the acquisition, development, redevelopment, ownership, management, and operation of a portfolio of office and mixed-use properties. The Parent Company owns its assets and conducts its operations through Brandywine Operating Partnership, L.P. (the “Operating Partnership”) and subsidiaries of the Operating Partnership. The Parent Company is the sole general partner of the Operating Partnership and, as of December 31, 2022, owned a 99.7% interest in the Operating Partnership. The Parent Company’s common shares of beneficial interest are publicly traded on the New York Stock Exchange under the ticker symbol “BDN.” The Parent Company, the Operating Partnership, and their consolidated subsidiaries are collectively referred to as the “Company.”

As of December 31, 2022, the Company owned 77 properties that contained an aggregate of approximately 13.6 million net rentable square feet (collectively, the “Properties”). The Company’s core portfolio of operating properties (the “Core Properties”) excludes development properties, redevelopment properties, and properties held for sale. The Properties were comprised of the following as of December 31, 2022:

	Number of Properties	Rentable Square Feet

In addition to the Properties, as of December 31, 2022, the Company owned 159.9 acres of land held for development. The Company also held a leasehold interest in one land parcel totaling 0.8 acres, acquired through a prepaid 99-year ground lease, and held options to purchase approximately 55.1 additional acres of undeveloped land. As of December 31, 2022, the total potential development that this inventory of land could support under current zoning and entitlements, including the parcels under option, amounted to an estimated 11.9 million square feet. 

As of December 31, 2022, the Company also owned economic interests in twelve unconsolidated real estate ventures (see Note 4 “Investment in Unconsolidated Real Estate Ventures” for further information). The Properties and the properties owned by the unconsolidated real estate ventures are primarily located in or near Philadelphia, Pennsylvania; Austin, Texas; Metropolitan Washington, D.C.; Southern New Jersey; and Wilmington, Delaware.

The Company conducts its third-party real estate management services business primarily through seven management companies (collectively, the “Management Companies”): Brandywine Realty Services Corporation (“BRSCO”), BDN Management Inc. (“BMI”), Brandywine Properties I Limited, Inc. (“BPI”), BDN Brokerage, LLC (“BBL”), Brandywine Properties Management, L.P. (“BPM”), Brandywine Brokerage Services, LLC (“BBS”), and BDN GC Services LLC (“BGCS”). Each of BRSCO, BMI and BPI is a taxable REIT subsidiary.

As of December 31, 2022, the Management Company subsidiaries were managing properties containing an aggregate of approximately 23.0 million net rentable square feet, of which approximately 13.6 million net rentable square feet related to Properties owned by the Company and approximately 9.4 million net rentable square feet related to properties owned by third parties and unconsolidated real estate ventures.
