Upwork Inc. UPWK Palo Alto, California — Area of real estate property

In February 2026, the Company commenced two new operating leases for expansion space at its corporate headquarters in Palo Alto, California, pursuant to an amendment to its existing office lease executed in January 2026. The amendment added Suite 125 (approximately 7,540 square feet) and Suite 302 (approximately 1,390 square feet), bringing total leased space at the location to approximately 21,615 square feet across three suites. The term for both suites runs through the existing lease expiration of September 2032. The Company concluded that the expansion represents two separate leases rather than a modification of the existing lease, and both suites are classified as operating leases. The Company evaluated the two existing renewal options, each for an additional three years, and determined they are not reasonably certain to be exercised; accordingly, they have not been included in the measurement of the right-of-use assets or lease liabilities. As a result of entering into these leases, the Company recognized right-of-use assets and lease liabilities of approximately $3.7 million for Suite 125 and approximately $0.7 million for Suite 302. Monthly rent payments, in aggregate under the leases, are approximately $0.1 million and are recorded within general and administrative expenses in the Company’s condensed consolidated statements of operations and comprehensive income.
