Alexandria Real Estate Equities, Inc. closed an amended and restated $5.0 billion unsecured senior line of credit, extending its maturity to Jan. 22, 2032, subject to conditions and two six-month extension options. The agreement became effective Sept. 24, 2026, and lowers the borrowing margin to SOFR plus 0.725% from SOFR plus 0.835%, an 11-basis-point reduction. Citibank serves as administrative agent, while a group of banks acts as arrangers and bookrunners. The company said the amendment supports liquidity, debt-maturity management and access to capital through market cycles.
