Accounting Policies [Abstract]
Equity method investment	Equity method investment The Company accounts for investments over which it has significant influence but not control under the equity method. The investment is initially recorded at cost and subsequently adjusted for the Company’s proportionate share of the investee’s net income or loss and are included in other assets in the accompanying consolidated balance sheets. The Company presents income or losses from equity investments as loss on equity method investment on the consolidated statements of operations and comprehensive (loss) income. If the share of losses exceeds the carrying value of the Company’s investment, the Company will suspend recognizing additional losses and will continue to do so unless it commits to providing additional funding or commits to guarantee investee liabilities. As of June 30, 2026, the Company had an equity method investment in Bisirna Therapeutics, Inc. (“Bisirna”).
Convertible debt	Convertible debt The Company accounts for its convertible debt instrument as a single unit of accounting, classified as a liability, as the conversion features do not require bifurcation as a derivative under ASC 815-15 and the convertible debt instrument was not issued at a substantial premium. The Company records debt issuance costs as contra-liabilities in the consolidated balance sheets at issuance, and amortizes them over the contractual term of the convertible debt instrument based on the effective interest method. The balance of the convertible notes presented in the consolidated balance sheets represents the principal balance of the convertible debt instrument less the unamortized portion of the debt issuance costs.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In July 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Asset. This ASU allows companies to elect a practical expedient to assume that conditions as of the balance sheet date will remain unchanged for the remaining life of the asset when estimating the expected credit losses of the asset. The ASU will become effective for the Company beginning October 1, 2026, and the Company is currently evaluating the impact on its consolidated financial statements and related disclosures. In January 2025, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, in November 2024, and ASU 2025-01, Clarifying the Effective Date. These updates require entities to provide disaggregated disclosures of income statement expenses. The ASUs do not affect the expense captions presented on the face of the income statement but instead require the disaggregation of certain expense captions into specified categories within the footnotes to the financial statements. The ASUs will become effective for the Company beginning October 1, 2027, and the Company is currently evaluating the impact on its consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-04, Debt-Debt with Conversion and Other Options (Subtopic 470-20), which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. ASU 2024-04 will become effective for the Company beginning October 1, 2026, and the Company is currently evaluating the impact on its consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to improve its income tax disclosure requirements. Under the guidance, entities must annually (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. This guidance became effective for the Company beginning on October 1, 2025. The Company is currently evaluating the impact of this new ASU on its financial statements and plans to adopt ASU 2023-09 on a prospective basis during this fiscal year.
