8. Convertible Senior Notes

In December 2021, the Company issued $1.1 billion aggregate principal amount of 0% convertible senior notes due 2027 (the “2027 Notes”), including the exercise in full of the initial purchasers’ option to purchase up to an additional $100.0 million principal amount of the 2027 Notes, in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The 2027 Notes are general unsecured obligations of the Company and will mature on January 15, 2027, unless earlier converted, redeemed, or repurchased. The 2027 Notes do not bear regular interest, and the principal amount of the 2027 Notes will not accrete. Special interest, if any, is payable semiannually in arrears on January 15 and July 15 of each year, beginning on July 15, 2022 (if and to the extent that special interest is then payable on the 2027 Notes). No special interest has been paid in connection with the 2027 Notes to date. The total net proceeds from the offering, after deducting initial purchasers’ discounts and debt issuance costs, were $1,080.5 million.

The initial conversion rate is 9.9936 shares of the Company’s Class A common stock per $1,000 principal amount of 2027 Notes (equivalent to an initial conversion price of approximately $100.06 per share of the Company’s Class A common stock), subject to adjustment as set forth in the indenture governing the 2027 Notes (the “Indenture”). The 2027 Notes are convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding October 15, 2026, only under the following conditions:

On or after October 15, 2026, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the 2027 Notes may convert all or any portion of their 2027 Notes at any time, at the option of the holder regardless of the foregoing conditions. Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, as the case may be, cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at the Company’s election, in the manner and subject to the terms and conditions provided in the Indenture. In addition, following certain corporate events that occur prior to the maturity date of the 2027 Notes or if the Company delivers a notice of redemption in respect of the 2027 Notes, the Company will, under certain circumstances, increase the conversion rate of the 2027 Notes for a holder who elects to convert its 2027 Notes in connection with such a corporate event or convert its 2027 Notes called (or deemed called) for redemption in connection with such notice of redemption, as the case may be.

During the three months ended March 31, 2025, the conditions allowing holders of the 2027 Notes to convert have not been met. The 2027 Notes were therefore not convertible and were classified as long-term debt on the Company’s condensed consolidated balance sheets as of March 31, 2025 and December 31, 2024.

The Company may redeem for cash all or any portion of the 2027 Notes (subject to the certain limitations described in the Indenture), at its option, on or after January 20, 2025, if the last reported sale price of the Company’s Class A common stock has been at least 130% of the conversion price for the 2027 Notes then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the 2027 Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date. If the Company redeems less than all of the outstanding 2027 Notes, at least $100.0 million aggregate principal amount of 2027 Notes must be outstanding and not subject to redemption as of, and after giving effect to, delivery of the relevant notice of redemption. No sinking fund is provided for the 2027 Notes.

The Company incurred $19.5 million of debt issuance costs related to the 2027 Notes. These costs are amortized to interest expense included within other income (expense), net on the condensed consolidated statements of operations over the contractual term of the 2027 Notes at an effective interest rate of 0.35%. Amortization of debt issuance costs was $0.9 million and $1.0 million for the three months ended March 31, 2025 and 2024, respectively.

Capped Calls

In connection with the pricing of the 2027 Notes and the exercise in full by the initial purchasers of their option to purchase additional 2027 Notes, the Company entered into capped call transactions with certain of the initial purchasers of the 2027 Notes or their respective affiliates and other financial institutions (the “Capped Calls”). The Capped Calls each have an initial strike price of approximately $100.06 per share, subject to certain adjustments, which corresponds to the initial conversion price of the 2027 Notes. The Capped Calls have initial cap prices of $138.02 per share, subject to certain adjustments. The Capped Calls associated with the 2027 Notes cover, subject to anti-dilution adjustments, approximately 11.0 million shares of the Company’s Class A common stock. The Capped Calls are expected generally to reduce the potential dilution to the Company’s Class A common stock upon any conversion of the 2027 Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted 2027 Notes, as the case may be, with such reduction and/or offset subject to a cap based on the cap price. For accounting purposes, the Capped Calls are separate transactions and not part of the terms of the 2027 Notes. As these transactions meet certain accounting criteria, the Capped Calls are recorded in stockholders’ equity and are not accounted for as derivatives. The cost of $91.0 million incurred to purchase the Capped Calls was recorded as a reduction to additional paid-in capital and will not be remeasured.
