Progress On Track to Meet or Exceed Targets

BXP (NYSE:BXP), the largest publicly traded developer, owner, and manager of premier workplaces in the United States, announced today strong progress on the multi-year business plan outlined at BXP's Investor Day in September 2025. The business plan is designed to optimize BXP's premier workplace positioning and portfolio with the overall goal of increasing FFO growth per share and deleveraging.

Tactics and targets of the business plan and highlights of BXP's execution include:

Lease space and increase occupancy in our premier portfolio, targeting 89% occupied (91% leased) by end of 2026, with improvement to 91% occupied (93% leased) by end of 2027.
- Completed more than 1.8 million square feet of leasing in Q4 2025 with a weighted average lease term of 10.1 years, including 425,000 square feet of leasing on currently vacant space and 620,000 square feet of leasing on expirations through year end 2027, increasing occupancy by 70 basis points to 86.7% (89.4% leased). Leasing volume for Q4 represented approximately 114% of BXP's historical Q4 leasing average.
- Quarter-to-date, executed approximately 600,000 square feet of leasing, with an additional 1.0 million square feet currently in negotiation and 1.4 million square feet in the proposal stage, providing meaningful visibility into continued occupancy growth. Of this 3.0 million square feet of leasing pipeline, approximately 1.5 million square feet is for currently vacant space and 820,000 square feet is for space expiring through 2027.
Optimize portfolio through execution of strategic sales program of land, residential, and non-strategic office assets, targeting $1.9 billion in net proceeds over three years.
- Completed dispositions with total net proceeds of more than $1.1 billion, with additional dispositions expected in 2026 that would bring estimated total net proceeds to $1.25 billion.
- Dispositions have included:
  - Eight suburban land parcels across the Boston, San Francisco, and Washington, DC regions generating aggregate net proceeds of approximately $250.0 million,
  - Three residential towers in Boston and Cambridge, Massachusetts and Reston, Virginia generating aggregate net proceeds of approximately $460.0 million, and
  - Three non-core office/lab properties in Needham, Massachusetts, South San Francisco, California, and Washington, DC generating aggregate net proceeds of approximately $397.0 million.
Pursue external growth through premier workplace developments in core markets and merchant development of residential assets with a majority capital partner.
- Launched the development of 343 Madison Avenue in Midtown Manhattan (29% pre-leased) and 725 12^th Street, Washington, DC (79% pre-leased).
- Construction of more than 1,400 units in three residential properties currently underway with entitlements for more than 5,000 additional units in various stages of design and permitting across regions.
Enhance position to secure a financial partner for a 30% to 50% leveraged interest in 343 Madison Avenue.
- Executed a lease for approximately 275,000 square feet with Starr, a global investment and insurance organization, securing approximately 29% of the 930,000 square foot premier workplace tower.
- In active discussions with multiple clients for additional space and projections remain on track for a stabilized unleveraged cash return of 7.5% to 8.0% upon delivery in 2029.

"Our clearly articulated business plan to lease space and improve occupancy, sell select assets, and reinvest in premier workplace development will allow BXP to grow FFO/share, deleverage, and improve portfolio quality over time," said Owen Thomas, Chairman and CEO, BXP. "We have made very strong progress executing all aspects of our plan over the last six months."
