Insights

Corporate finance and real estate analyst

Amprius pays $20M to exit a large, recently started lease.

Amprius Technologies terminated a 15-year lease on about 774,155 rentable square feet in Brighton, Colorado, effective January 31, 2026. The lease started in June 2024, so this exit comes relatively early in the term and ends most future rights and obligations under that agreement.

The company agreed to a $20,000,000 termination fee, while the landlord will return a security deposit currently held as a $1,200,000 letter of credit by February 5, 2026. Previously, base rent was approximately $300,000 plus about $190,000 of additional rent, with base rent scheduled to rise about 3.3% annually.

This represents a meaningful near-term cash outflow in exchange for eliminating long-term lease commitments on a large facility. The impact on Amprius’ liquidity and operating footprint will depend on its broader capacity plans and will likely be discussed further when the full lease termination agreement is filed with the Form 10-K for the period ending December 31, 2025.
