Breakthrough Properties Secures $465 Million CMBS Loan to Refinance San Diego Life Sciences Campus

Breakthrough Properties has shared an update. The company has secured a $465 million, five-year fixed-rate commercial mortgage-backed securities (CMBS) loan to refinance Torrey Heights, its 520,000-square-foot life sciences campus in San Diego. The financing was provided by a syndicate of major lenders including JP Morgan Chase, Deutsche Bank, and Goldman Sachs. Torrey Heights is slated to become the new headquarters of Pfizer’s oncology division this year, with additional tenants including Becton, Dickinson & Company, Charles River Laboratories, Actio Biosciences, and Architect Therapeutics.

For investors, the refinancing materially strengthens Breakthrough Properties’ capital structure for this flagship asset by locking in fixed-rate funding over a five-year horizon and potentially reducing refinancing and interest-rate risk amid an uncertain rate environment. Securing a sizeable CMBS facility from top-tier banks also suggests strong lender confidence in both the property’s cash-flow profile and the underlying San Diego life sciences market. The presence of high-quality tenants, led by Pfizer’s oncology headquarters, supports long-term occupancy stability and could underpin resilient rental income and asset valuation. Strategically, this transaction reinforces Breakthrough Properties’ positioning as a key owner-operator in core life sciences clusters and may enhance its ability to raise future capital, pursue additional development or acquisition opportunities, and weather sector or macroeconomic volatility driven by capital markets conditions.
