Fair Value Measurement Fair Value Measurement
The carrying amounts of cash and cash equivalents, receivables, prepaid expenses, accounts payable and accrued expenses approximate their fair values due to the short-term nature of these instruments. Cash and cash equivalents consist primarily of cash and highly liquid investments with original maturities of three months or less at the time of purchase; accordingly, their carrying amounts approximate fair value. Cash and cash equivalents are valued based upon quoted market prices in active markets for identical assets and are therefore classified as Level 1 assets. Money market funds are open-end mutual funds that invest in cash, government securities, and/or repurchase agreements that are collateralized fully. To the extent that these funds are valued based upon the reported net asset value, they are categorized in Level 1 of the fair value hierarchy.
Short-term marketable securities consisted of U.S. Treasury bills that are classified within Level 2 of the fair value hierarchy are valued based on other observable inputs, including broker or dealer quotations, alternative pricing sources or U.S. Government Treasury yield of appropriate term.
The following tables provide information by level for assets and liabilities that are measured at fair value on a recurring basis:

There were no transfers in or out of Level 1, 2 and 3 measurements for the six months ended June 30, 2026 and the year ended December 31, 2025. As of June 30, 2026 and December 31, 2025, there were no securities within Level 3 of the fair value hierarchy.
As of June 30, 2026 and December 31, 2025, the fair value of the 2024 Loan (as defined in Note 10) was $85.6 million and $85.5 million, respectively. The fair value was determined on the basis of its net present value and is considered Level 2 in the fair value hierarchy.
In May 2026, the Company determined that the Tarzana facility no longer met the criteria for classification as held for sale and reclassified it as held and used. Accordingly, depreciation resumed prospectively based on the adjusted carrying value. Each asset was measured individually at the lower of its carrying amount before the Tarzana facility was classified as held for sale, with the depreciable assets adjusted for depreciation expense that would have been recognized had the Tarzana facility been continuously classified as held and used, or its fair value as of the date of the subsequent decision not to sell. The fair values of these assets are classified as Level 3 in the fair value hierarchy due to a mix of unobservable inputs utilized. As a result, the Company recognized a net remeasurement loss of $0.2 million during the second quarter of 2026, which is reflected in both the three and six months ended June 30, 2026 in the condensed consolidated statements of operations and comprehensive loss within the line item “restructuring and impairment charges, net.” See Note 3 and Note 14.
