Accounting Policies [Abstract]  
Basis of Presentation Basis of Presentation
The Company’s fiscal year ends on March 31, and its fiscal quarters end on June 30, September 30, and December 31.
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and follow the requirements of the United States Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, these unaudited condensed consolidated financial statements do not include all of the information and disclosures required by U.S. GAAP for complete financial statements as certain footnotes or other financial information that are normally required by U.S. GAAP can be condensed or omitted. The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements.
These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K (the “Annual Report”) for the fiscal year ended March 31, 2026 filed with the SEC. The unaudited condensed consolidated balance sheet at March 31, 2026 has been derived from the audited consolidated financial statements at that date. In the opinion of management, the unaudited condensed consolidated financial statements include all adjustments, which include only normal recurring adjustments, that are considered necessary to present fairly the financial position of the Company and its results of operations and cash flows for the interim periods presented. Operating results for the three months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2027, for any other interim period, or for any other future year.
Any references in these notes to applicable accounting guidance are meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). The unaudited condensed consolidated financial statements include the accounts of RSL and the subsidiaries in which it has a controlling financial interest, most often through a majority voting interest. All intercompany balances and transactions have been eliminated in consolidation.
Principles of Consolidation Principles of Consolidation
For consolidated entities where the Company owns or is exposed to less than 100% of the economics, the Company records net loss attributable to noncontrolling interests in its unaudited condensed consolidated statements of operations equal to the noncontrolling interest’s proportionate share of the respective operations. The Company presents noncontrolling interests as a component of shareholders’ equity on its unaudited condensed consolidated balance sheets.
The Company accounts for changes in its ownership interest in its subsidiaries while control is retained as equity transactions. The carrying amount of the noncontrolling interest is adjusted to reflect the change in the ownership interest in the subsidiary. Any difference between the fair value of the consideration received or paid and the amount by which the noncontrolling interest is adjusted is recognized within shareholders’ equity attributable to RSL.
Use of Estimates 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. The Company regularly evaluates estimates and assumptions related to assets, liabilities, costs, expenses, contingent liabilities, share-based compensation and research and development costs. The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.
Concentrations Concentrations
Financial instruments that potentially subject the Company to credit risk concentration include cash, cash equivalents, and marketable securities. The Company maintains cash deposits, cash equivalents, and marketable securities in highly-rated, federally-insured financial institutions in excess of federally insured limits. The Company has established guidelines relative to diversification and maturities to maintain safety and liquidity. The Company has not experienced any credit losses related to these financial instruments and does not believe that it is exposed to any significant credit risk related to these instruments.
The Company has long-lived assets in different geographic locations. As of June 30, 2026 and March 31, 2026, a majority of the Company’s long-lived assets were located in the United States (“U.S.”).
Segment Reporting Segment ReportingOperating segments are defined as components of an entity about which separate, discrete information is available for evaluation by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker views the operations and manages the business in a single operating and reportable segment focused on the discovery, development and commercialization of medicines and technologies. The accounting policies of the segment are the same as those described in this Note 2, “Summary of Significant Accounting Policies.”
Cash, Cash Equivalents, and Restricted Cash Cash, Cash Equivalents, and Restricted Cash
Cash and cash equivalents include cash deposits in banks and all highly liquid investments that are readily convertible to cash. The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Cash equivalents consist of amounts invested in money market funds.
Cash as reported in the accompanying condensed consolidated statements of cash flows includes the aggregate amounts of cash, cash equivalents, and restricted cash as presented on the accompanying condensed consolidated balance sheets as follows (in thousands):
June 30, 2026March 31, 2026
Cash and cash equivalents$1,248,456 $1,419,232 
Restricted cash (included in “Other current assets”)4,195 3,858 
Restricted cash (included in “Other assets”)7,892 7,892 
Cash, cash equivalents and restricted cash$1,260,543 $1,430,982 
Marketable Securities Marketable Securities
The Company considers all highly liquid investments in securities with original maturities of greater than three months at the time of purchase to be marketable securities. Marketable securities, including those that have maturity dates beyond one year from the balance sheet date, are included in current assets on the condensed consolidated balance sheets due to their availability for use in current operations. As of June 30, 2026, marketable securities consist of U.S. Treasury securities and corporate bonds. All of the Company’s marketable securities are classified as available-for-sale and are carried at fair value as of June 30, 2026. Unrealized holding gains and losses, net of income taxes, on available-for-sale debt securities are reported as a separate component of accumulated other comprehensive income in stockholders’ equity until realized. The cost of available-for-sale securities sold and the amount reclassified out of accumulated other comprehensive income into earnings is determined using the specific identification method. Prior to December 31, 2025, a portion of the Company’s marketable securities were classified as held-to-maturity and carried at amortized cost. Interest income is recorded as earned within “Interest income” in the condensed consolidated statements of operations.
Contingencies Contingencies
The Company may, from time to time, be a party to various disputes and claims arising from normal business activities. The Company continually assesses any litigation or other claims it may confront to determine if an unfavorable outcome would lead to a probable loss or reasonably possible loss which could be estimated. The Company accrues for all contingencies at the earliest date at which the Company deems it probable that a liability has been incurred and the amount of such liability can be reasonably estimated. If the estimate of a probable loss is a range and no amount within the range is more likely than another, the Company accrues the minimum of the range. In the cases where the Company believes that a reasonably possible loss exists, the Company discloses the facts and circumstances of the contingent loss, including an estimable range, if possible.
Investments Investments
Investments in equity securities for which the Company does not have control or significant influence may be accounted for using (i) the fair value option, if elected, (ii) fair value through earnings, if fair value is readily determinable or (iii) for equity investments without readily determinable fair values, the measurement alternative to measure at cost adjusted for any impairment and observable price changes, as applicable. The election to use the measurement alternative is made for each eligible investment.
The Company has elected the fair value option to account for certain investments over which the Company has significant influence. The Company believes the fair value option best reflects the underlying economics of these investments. See Note 4, “Equity Method Investments.”
Fair Value Measurements Fair Value Measurements
The Company utilizes fair value measurement guidance prescribed by U.S. GAAP to value its financial instruments. The guidance establishes a fair value hierarchy for financial instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. Fair value is defined as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the reporting date. As a basis for considering market participant assumptions in fair value measurements, the guidance establishes a three-tier fair value hierarchy that distinguishes among the following:
•Level 1-Valuations are based on unadjusted quoted prices in active markets for identical assets or liabilities.
•Level 2-Valuations are based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly.
•Level 3-Valuations are based on inputs that are unobservable (supported by little or no market activity) and significant to the overall fair value measurement.
To the extent the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
The Company’s financial instruments include shares of common stock of Arbutus Biopharma Corporation (“Arbutus”) and Class A units of Heracles Parent, L.L.C. (“Datavant”). The Company’s financial instruments also include cash; cash equivalents, consisting of money market funds; marketable securities, consisting of U.S. Treasury securities and corporate bonds; receivables; and accounts payable.
The shares of Arbutus common stock are classified as Level 1, and their fair value is determined based upon quoted market prices in active markets. The Class A units of Datavant and liability instruments issued are classified as Level 3 within the fair value hierarchy as the assumptions and estimates used in the valuations are unobservable in the market. Cash, receivables and accounts payable are stated at their respective historical carrying amounts, which approximate fair value due to their short-term nature. Money market funds are included in Level 1 of the fair value hierarchy and are valued at the closing price reported by an actively traded exchange. Available-for-sale marketable securities, consisting of U.S. Treasury securities and corporate bonds, are included in Level 2 of the fair value hierarchy. These securities are valued using pricing valuation models that incorporate observable market inputs.
Foreign Currency Foreign Currency
The Company’s functional and reporting currency is the U.S. dollar. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in “Other expense, net” in the accompanying condensed consolidated statements of operations. For the three months ended June 30, 2026 and 2025, the Company had a foreign currency transaction gain of $0.8 million and a foreign currency transaction loss of $6.8 million, respectively.
Significant Accounting Policies /Recently Issued Accounting Pronouncements Significant Accounting Policies
There were no significant changes to the Company’s significant accounting policies from those disclosed in the Company’s Annual Report for the year ended March 31, 2026.
Recently Issued Accounting Pronouncements
From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that the Company adopts as of their specified effective dates.
In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses,” which requires disclosure of certain costs and expenses on an interim and annual basis in the notes to the financial statements. The amendments are effective for fiscal years beginning after December 15, 2026 and for interim periods within fiscal years beginning after December 15, 2027. This ASU is applicable to the Company’s Annual Report for the fiscal year ended March 31, 2028, and subsequent interim periods, with early adoption permitted. The amendments can be adopted either (i) prospectively to financial statements issued for reporting periods after the effective date of this ASU or (ii) retrospectively to any or all prior periods presented in the financial statements. The Company expects adoption of this ASU will result in additional disclosures in line with the requirements of ASU 2024-03.
