Management Comments

Stephen E. Budorick, COPT Defense's President & Chief Executive Officer, commented, "Our Defense/IT investment strategy, which concentrates our portfolio near priority U.S. defense installations, continued to generate excellent results during the third quarter. FFO per share exceeded the midpoint of our guidance range by $0.02. Based on this outperformance, and our forecast for the remainder of the year, we increased the midpoint of 2025 FFO per share guidance by $0.03 to $2.70, which implies 5.1% year-over-year growth, and is $0.04 above our initial guidance.

We are exceeding our plan in several areas and raised 2025 guidance on multiple key metrics. We increased the midpoint of 2025 guidance for same property cash NOI growth by 75 basis points to 4.0%, cash rent spread on renewals by 200 basis points to 2%, and year-end same property occupancy by 20 basis points to 94.2%. In addition, with 432,000 square feet signed in the first nine months of the year, and a strong pipeline of deals in advanced negotiations, we raised our target for vacancy leasing by 11% from 450,000 square feet to 500,000 square feet. Our revised target is 25% higher than our initial target of 400,000 square feet, and reflects the depth of tenant demand to support priority missions. Additionally, in October, we successfully closed on three financings which pre-fund our 2026 bond maturity and provide $400 million of additional liquidity to fund our external growth.

We committed $72 million of capital to two new investments in September and October, both of which expand our strategic relationships with existing Defense/IT tenants. In September, we commenced construction on a 101,000 square foot build-to-suit development for Yulista, our 14^th largest tenant, at our Redstone Gateway park in Huntsville, and in October, we acquired a 142,000 square foot office building in Chantilly, Virginia, which is 100% leased to a top 20 U.S. Defense Contractor. This acquisition exceeds our development yield threshold, is accretive to FFO per share, and reinforces our position as the dominant owner in the highly-leased and supply-constrained Westfields submarket, as we own roughly one-third of the 4 million square feet of office inventory.

We have produced excellent results for the first nine months of the year, we expect a strong fourth quarter and we continue to anticipate compound annual FFO per share growth of over 4% between 2023 to 2026."
