Item 1.02 Termination of a Material Definitive Agreement.

On June 4, 2025, Kronos Bio, Inc. (the “Company”) entered into a Lease Termination Agreement (the “Termination Agreement”) with BMR-Rogers Street LLC, a Delaware limited liability company (the “Landlord”), pursuant to which the Company and the Landlord agreed to terminate that certain Office Lease, dated February 28, 2020, as amended (the “Original Lease”), related to the Company’s office and laboratory space located at 301 Binney Street, Cambridge, Massachusetts. Prior to the Termination Agreement, the term of the Original Lease was set to expire on February 28, 2031. Pursuant to the Termination Agreement, the Original Lease will be terminated effective as of 11:59 p.m. Eastern time on June 30, 2025 (the “Early Termination Date”). As consideration for the Termination Agreement, the Company agreed to pay Landlord approximately $22.5 million within three business days of the execution of the Termination Agreement, and the Landlord agreed to cancel and return to the Company the approximately $2.0 million held as a security deposit within 60 days following the Early Termination Date. As a result of the termination of the Original Lease, and related costs the Company no longer expects to incur in connection with the Original Lease, the Company estimates approximately $18.2 million in aggregate additional cost savings.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.
