Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies During the three months ended March 31, 2026, there have been no significant changes to the Company’s summary of significant accounting policies contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the SEC on March 6, 2026. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to, the valuation of share-based awards, income taxes, prepaids, and accruals for research and development activities. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable. However, actual results could differ from those estimates. Impairment or Disposal of Long-lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying value of such assets may not be recoverable in accordance with the guidance in Financial Accounting Standards Board (“FASB”) Accounting Standard Codification Topic 360, Property, Plant and Equipment (“ASC 360”). The Company’s long-lived assets include properties and equipment and right of use (“ROU”) assets. For long-lived assets, impairment is recognized when the undiscounted cash flows used in the test for recoverability is less than their carrying value, and the fair value of the long-lived asset is below the carrying value. In the event impairment exists, the long-lived asset will be written down to its fair value, and an impairment loss is recorded as the difference between the carrying value and fair value. During the three months ended March 31, 2026, the Company recognized an impairment charge of $0.7 million related to its office and laboratory lease ROU asset and underlying leasehold improvements and equipment. The Company determined the fair value of each asset group using a discounted cash flow model based on the expected sublease income utilizing its current borrowing rate. The inputs utilized for fair value measurement are unobservable and considered level 3 in the fair value hierarchy. The impairment charge was recorded in “Research and development expense” in the Consolidated Statement of Operations and Comprehensive Loss, and reduced the carrying amount of the underlying long-lived assets to fair value.
