Basis of Accounting	These condensed consolidated financial statements have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments consisting only of normal recurring adjustments necessary for a fair presentation have been reflected in these condensed consolidated financial statements. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2026. The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts that are reported in the condensed consolidated financial statements and accompanying disclosures. Although these estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may differ from those estimates. These condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “2025 Form 10-K”). The Company has one operating and reportable segment. See Note 19 for more information.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements The Company adopted all applicable standards effective as of December 31, 2025, within these condensed consolidated financial statements. There was no material impact as a result. There are no newly issued standards since December 31, 2025 that are applicable to the Company.
Fair Value Measurements	Fair Value Measurements The Company values its available-for-sale securities and certain liabilities based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability in fair value measurements, a fair value hierarchy that prioritizes observable and unobservable inputs is used to measure fair value into three broad levels, which are described below: Level 1 – Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2 – Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in inactive markets or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable market data. Level 3 – Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs to the extent possible. In addition, the Company considers counterparty credit risk in its assessment of fair value. The asset or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. The following is a description of the valuation methodologies used for certain assets and liabilities measured at fair value, which are not considered Level 1 items. Corporate bonds – Valued at the closing price reported on the active market on which the individual securities, all of which have counterparts with high credit ratings, are traded. Commercial paper – Value is based on yields currently available on comparable securities of issuers with similar credit ratings. Money market funds – Valued at the net asset value (“NAV”) of units of a collective fund. The NAV is used as a practical expedient to estimate fair value. This practical expedient is not used when it is determined to be probable that the fund will sell the investment for an amount different than the reported NAV. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.
