Highest Annual Vacancy Leasing Level in 12 Years

Illustrates the Durability of Portfolio

Corporate Office Properties Trust (NYSE:OFC) ("COPT" or the "Company") completed 801,000 square feet of vacancy leasing during 2022 with a weighted-average lease term of over 7 years, the Company's highest annual vacancy leasing level in 12 years.

This record leasing volume is 30% higher than the 616,000 square feet achieved in 2021, exceeds the recent high watermark of 784,000 square feet achieved in 2019 and is 40% higher than the prior 5-year average for vacancy leasing, further demonstrating the strength of our Defense demand drivers.

The Company completed 173,000 square feet of vacancy leasing in 4Q22, which follows 351,000 square feet in 3Q22, which was the highest quarterly total in 12 years.

COPT's management attributes this leasing success to the continued growth in Defense spending in the priority missions we support, and tenants continued need for office space to conduct work for those priority defense missions, which has materialized into elevated demand for our properties.
