Insights

Equity & Credit Analyst

Lease exit adds near‑term cost but clarifies cash runway.

Passage Bio is exiting a long‑term laboratory lease by paying a $4.8 million termination fee plus accrued rent. The lease covered roughly 62,000 square feet and originally ran 15 years from March 2021, so the termination removes a sizable long-duration commitment.

The company had already stopped using the space after a restructuring in January 2025, so this step aligns contractual obligations with its reduced footprint. Management now states that cash and cash equivalents are expected to fund operations through the first quarter of 2027, while noting this depends on assumptions that may change.

For investors, the key elements are the one-time cash outlay and the updated funding horizon. Subsequent financial reports may show how this termination fee and the elimination of future lease costs affect operating expenses and overall liquidity over time.

Item 1.02 Termination of a Material Definitive Agreement.

On March 4, 2026, Passage Bio, Inc. (the “Company”) and Hopewell Campus Owner LLC (the “Landlord”) entered into a lease termination agreement (the “Termination Agreement”) with respect to that certain lease agreement dated December 15, 2020 between the Company and Landlord (the “Hopewell Lease”). Pursuant to the Termination Agreement, the Company agreed to pay the Landlord a termination fee of approximately $4.8 million as well as accrued rent through February 14, 2026.

Pursuant to the Hopewell Lease, the Company had leased approximately 62,000 square feet of laboratory space. This lease had a 15-year term from the lease commencement date of March 2021. Following the Company’s restructuring in January 2025, the Company ceased all operations at the facilities subject to the Hopewell Lease. Following the execution of the Termination Agreement, the Company maintains the expectation that cash and cash equivalents will fund operations through the first quarter of 2027. We have based this estimate on assumptions that may prove to be wrong, and our operating plan may change as a result of factors currently unknown to us. As a result, we could deplete our capital resources sooner than we currently expect.
