Kailera Therapeutics KLRA Geographic — Area Of Office Space

In March 2025, the Company executed a new, seven-year, non-cancellable operating lease agreement for approximately 39,500 square feet of office space in Waltham, Massachusetts for its corporate headquarters. The lease commenced in October 2025, following completion of construction to prepare the premises for the Company’s intended use. The lease provided for base rent of $2.2 million for the first year, which will increase by approximately 2% each year. The Company’s lease payments also include real estate taxes and other operating expenses allocable to the leased premises, which exceed base year amounts. The Company has the option to extend the lease for one additional five-year term with base rent calculated on the then-market rate. In accordance with the lease agreement, the Company maintained a letter of credit of $0.8 million, which is refundable at the end of the lease term. As of March 31, 2026, the underlying cash balance collateralizing this letter of credit was classified as restricted cash (non-current) on the condensed consolidated balance sheets based on the release date of the restrictions of this cash. In connection with the new lease agreement, the Company amended its previous lease in Waltham, Massachusetts to extend the lease term to end shortly after the lease commencement date of its new lease agreement, which occurred in the fourth quarter of 2025.
