Excluded from the lease obligation table above is a commercial lease agreement (the “Lease”) entered into by and between the Company and Sunnyvale Office Acquisition, LLC, as of September 11, 2025, pursuant to which the Company agreed to lease an aggregate of approximately 75,556 rentable square feet for a new corporate headquarters in Sunnyvale, California, which will be recognized as an operating lease upon the lease commencement date. The actual timing of lease commencement for accounting purposes, as well as the Company’s obligation to begin making payments and recognizing rental and other expenses, is dependent upon when the space is made available to the Company and the Company obtains control of the underlying asset. The Company’s current estimate of the total estimated aggregate base rent payments, excluding the renewal option and option to expand into additional space, for this leased office space are approximately $62.1 million.
