Recurring Fair Value Measurements    
Fair value represents the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Observable inputs are based on market data obtained from independent sources. The fair value hierarchy is based on the following three levels of inputs, of which the first two are considered observable and the last one is considered unobservable:
•Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
•Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
•Level 3 – Unobservable inputs.

At September 30, 2025 and December 31, 2024, cash equivalents of $306.8 million and $436.7 million, respectively, consisted of money market funds with original maturities of three months or less.

The estimated fair value of Convertible Senior Notes is based on market rates and the closing trading price of the Convertible Senior Notes as of September 30, 2025 and December 31, 2024 and is classified as Level 2 in the fair value hierarchy. At September 30, 2025 and December 31, 2024, the estimated fair value of the Company's 2024 Term Loan B Facility was $362.5 million and $368.2 million, respectively.
