[1] | “Maturity Date” is the stated maturity date under each applicable indenture governing such notes, unless earlier converted, redeemed, or repurchased in accordance with their terms.
[2] | Holders may receive additional or special interest under specified circumstances as outlined under each applicable indenture governing the Convertible Notes.
[3] | The 2029 Convertible Notes and the 2030B Convertible Notes do not bear regular interest. Additionally, the 2027 Convertible Notes did not bear regular interest prior to their redemption.
[4] | “Issuance Costs” reflect the customary offering expenses associated with each of the Convertible Notes. The Company accounts for these issuance costs as a reduction to the principal amount of the respective Convertible Notes and amortizes the issuance costs to interest expense from the respective debt issuance dates through the earlier of the “Maturity Date” or the “Date of Holder Put Option,” if applicable, at the “Effective Interest Rate” stated in the table.
[5] | The “Initial Conversion Rate” is stated in shares of the Company’s class A common stock per $1,000 principal amount. The conversion rates are subject to customary anti-dilution adjustments. In addition, following certain events that may occur prior to the respective maturity dates or if the Company delivers a notice of redemption, the Company will increase the conversion rate for a holder who elects to convert its respective Convertible Notes in connection with such corporate event or notice of redemption, as the case may be, in certain circumstances as provided in each indenture governing the respective Convertible Notes.

For the 2027 Convertible Notes, the date presented is the date on which the Company delivered its notice of full redemption of the 2027 Convertible Notes, which resulted in the 2027 Convertible Notes being convertible at any time thereafter until 5:00pm New York City time, on February 20, 2025. See below under “Conversions and Redemption of Convertible Notes” for further information.
[8] | Prior to the respective dates, the Convertible Notes are convertible only under the following circumstances: i. during any calendar quarter (and only during such calendar quarter) commencing after the calendar quarter ended on June 30, 2024 for the 2030A Convertible Notes and 2031 Convertible Notes, on September 30, 2024 for the 2032 Convertible Notes, on December 31, 2024 for the 2028 Convertible Notes, on Ma rch 31, 2025 for the 2029 Convertible Notes, or on June 30, 2025 for the 2030B Convertible Notes, if the last reported sale price of the Company’s class A common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price of the respective Convertible Notes on each applicable trading day; ii. during the five business day period after any five consecutive trading day period (the “measurement period”) in which the “trading price” (as defined under each applicable indenture governing the respective Convertible Notes) per $1,000 principal amount of the respective Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s class A common stock and the applicable conversion rate on each such trading day; iii. (a) in the case of the 2028 Convertible Notes, 2029 Convertible Notes, 2030A Convertible Notes, 2031 Convertible Notes and 2032 Convertible Notes, the Company calls any or all of such Convertible Notes for redemption, then a holder may surrender all or any part of such of its Convertible Notes as called for redemption for conversion at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; and (b) in the case of the 2030B Convertible Notes, the Company calls any 2030B Convertible Notes for redemption, then the holders of such 2030B Convertible Note may convert such 2030B Convertible Notes at any time before the close of business on the second business day immediately before the related redemption date; and iv. upon occurrence of specified corporate events as described in each applicable indenture governing the respective Convertible Notes.
[9] | The Company may redeem for cash all or a portion of the Outstanding Convertible Notes at its option, on or after the stated dates, if the last reported sale price of the Company’s class A common stock has been at least 130% of the conversion price of the respective Convertible Notes then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides a notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption. The redemption price will be equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. See below “Conversions and Redemption of Convertible Notes” subsection for information regarding the Company’s redemption of the 2027 Convertible Notes.
[10] | Redemption Date” for the 2027 Convertible Notes is the date on which the Company redeemed all outstanding 2027 Convertible Notes.
[11] | “Date of Holder Put Option” represents the respective dates upon which holders of the 2028 Convertible Notes, 2029 Convertible Notes, 2030A Convertible Notes, 2030B Convertible Notes, 2031 Convertible Notes, and 2032 Convertible Notes each have a noncontingent right to require the Company to repurchase for cash all or any portion of their respective notes at a repurchase price equal to 100% of the principal amount of such notes to be repurchased, plus any accrued and unpaid interest to, but excluding the repurchase date.
