(1) The original principal of the 2027 Notes at issuance was recorded at fair value of $196.2 million, which is equal to the exchanged principal of $176.3 million of the 2026 Notes and cash consideration received of $19.9 million. After the exchange on July 2, 2025, the remaining fair value of the principal recorded at issuance of the 2027 Notes was $46.2 million. Convertible Senior Notes due 2030 On July 2, 2025, the Company issued its senior, unsecured 2030 Notes, consisting of (i) $20.0 million aggregate principal amount of 2030 Notes issued in exchange for $20.0 million aggregate principal amount of the Company’s outstanding 2026 Notes, and (ii) $224.1 million aggregate principal amount of 2030 Notes issued in exchange for $150.0 million aggregate principal amount of the Company’s outstanding 2027 Notes. The interest on the 2030 Notes is payable semi-annually in arrears on each June 30 and December 30 of each year. The 2030 Notes are convertible into Common Stock or a combination of cash and Common Stock, at the Company’s election. Subject to certain conditions, holders of the 2030 Notes may convert all or any portion of their 2030 Notes at their option at any time on or after March 31, 2030, until the close of business on the second scheduled trading day immediately preceding the maturity date. In addition, if specified events occur in a calendar quarter prior to March 31, 2030, the holders may elect to convert on an effective date of such event. Based on the closing price of the Common Stock of $24.06 as of June 30, 2026, the if-converted value of the 2030 Notes was less than the principal amount. The initial conversion rate of the 2030 Notes is 18.503 shares of Company Common Stock per $1,000 principal amount of 2030 Notes, which is equivalent to an initial conversion price of approximately $54.04 per share, subject to customary adjustments. In addition, upon the occurrence of a make-whole fundamental change, as defined in the 2030 Notes Indenture, or if we exercise the optional redemption, we will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert its 2030 Notes in connection with such a make-whole fundamental change or redemption. In no event will the conversion rate be increased to exceed 27.7546 shares of the Company’s Common Stock per $1,000 principal amount of the 2030 Notes, subject to adjustments. The Company is entitled to not effect any conversion that will result in any holder thereof, together with any Attribution Parties, beneficially owning more than 4.9% of the Company's Common Stock, after giving effect to such conversion. The Company’s obligation to deliver any shares of Common Stock that will result in any holder thereof to exceed the 2030 Notes Exchange Cap is not extinguished and is suspended until such holder advises the Company in writing that it may receive the 2030 Notes Excess Shares without exceeding the 2030 Notes Exchange Cap. The Company has the conditional right to redeem the notes for cash on or after July 2, 2028. The redemption price will be 100.0% of the principal amount, plus accrued and unpaid interest. No sinking fund is provided for the 2030 Notes. The Company has the right to repurchase notes in the open market or through other means, without the consent of holders and without prior notice. The 2030 Notes Indenture contains customary provisions relating to events of default. If an event of default occurs and is continuing, the principal amount of the 2030 Notes and any accrue d and unpaid interest may be declared immediately due and payable. In the case of bankruptcy or insolvency, the principal amount of the 2030 Notes and any accrued and unpaid interest would automatically become immediately due and payable. The 2030 Notes will be considered in default if there is a default by the Company or any of its significant subsidiaries with respect to indebtedness for borrowed money of at least $75.0 million. The carrying value of the 2030 Notes was determined by deducting third party transaction costs incurred in connection with the issuance of the 2030 Notes of $2.3 million from the 2030 Notes fair value of $267.7 million at issuance. The fair value of the principal of the 2030 Notes at issuance was determined using a lattice model. The transaction costs are amortized as interest expense. The fair value of the 2030 Notes at issuance exceeded the principal amount by $23.6 million. This premium is being amortized over the term of the 2030 Notes as a reduction of interest expense. Together with the cash interest, the amortization of debt issuance costs and debt premium result in the annual effective interest rate of 2.99% over the term of the 2030 Notes. We classified the fair value of the 2030 Notes as a Level 3 measurement due to the lack of observable market data over fair value inputs such as our stock price volatility over the term of the 2030 Notes and our cost of debt. The estimated fair value of the 2030 Notes as of June 30, 2026 and December 31, 2025 was $234.7 million and $223.4 million, respectively, and was determined using a lattice model. During the three and six months ended June 30, 2026, we recognized interest costs on the 2030 Notes as follows (in thousands):
|  | Three Months Ended June 30, |  | Six Months Ended June 30,
| 2026
Contractual interest |  | $ | 2,974 |  |  | $ | 5,949 |
Amortization of debt premium and debt issuance costs, net |  | (1,015) |  |  | (2,023) |
Total |  | $ | 1,959 |  |  | $ | 3,926 |
Convertible Senior Secured Notes due 2027 In November 2024, the Company issued $197.3 million aggregate principal amount of the 2027 Notes to the 2027 Notes Offering Participants in a private offering. The interest on the 2027 Notes is payable semi-annually in arrears on March 15 and September 15 of each year. The initial conversion rate of the 2027 Notes is 33.333 shares of Common Stock per $1,000 principal amount of 2027 Notes, which is equivalent to an initial conversion price of approximately $30.00 per share, subject to customary adjustments. The 2027 Notes are convertible into Common Stock or a combination of cash and Common Stock, at the Company's election. Upon the occurrence of a make-whole fundamental change, we will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert its 2027 Notes in connection with such make-whole fundamental change. The Company is entitled to not effect any conversion that will result in any holder thereof, together with any Attribution Parties, beneficially owning more than 9.9% of the Company's Common Stock, after giving effect to such conversion. The Company’s obligation to deliver any shares of Common Stock that will result in any holder thereof to exceed the 2027 Notes Exchange Cap is not extinguished and is suspended until such holder advises the Company in writing that it may receive the 2027 Notes Excess Shares without exceeding the 2027 Notes Exchange Cap. The 2027 Notes will be considered in default if there is a default by the Company or any of its significant subsidiaries with respect to indebtedness for borrowed money of at least $35.0 million. Concurrent with the issuance of the 2030 Notes in exchange for a large portion of the 2027 Notes, all of the negative covenants and related provisions from the 2027 Notes Indenture were eliminated, and all of the liens on the collateral securing the obligations under the 2027 Notes were released. In addition, the Company was relieved of its obligation to pay additional interest of 2.5% per annum of the 2027 Notes in the event that it failed to sell or pledge certain of its assets as part of the collateral for the 2027 Notes. Following the issuance of the 2030 Notes and partial exchange of the 2027 Notes in July 2025, the remaining outstanding principal of the 2027 Notes was $47.3 million and the annual effective interest rate is 7.27%. We classified the fair value of the 2027 Notes as a Level 3 measurement due to the lack of observable market data over fair value inputs such as our stock price volatility over the term of the 2027 Notes and our cost of debt. The estimated fair value of the 2027 Notes as of June 30, 2026 and December 31, 2025 was $50.4 million and $48.8 million, respectively, and was determined using a lattice model. For the three and six months ended June 30, 2026 and 2025, we recognized interest costs on the 2027 Notes as follows (in thousands):
| Three Months Ended June 30, |  | Six Months Ended June 30,

Contractual interest | $ | 739 |  |  | $ | 3,082 |  |  | $ | 1,477 |  |  | $ | 6,164 |

Convertible Senior Notes due 2026 On March 15, 2026, the Company paid off the remaining $33.7 million aggregate principal amount of the 2026 Notes upon their scheduled maturity. The total payment included the outstanding principal balance and all accrued and unpaid interest up to the maturity date. The repayment of principal is reflected in cash flows used in financing activities, and the payment of accrued interest is reflected in cash flows used in operating activities, each within the Condensed Consolidated Statement of Cash Flows as of June 30, 2026. Prior to the repayment of the 2026 Notes upon maturity, the interest on the 2026 Notes was payable semi-annually in arrears on March 15 and September 15 of each year. The annual effective interest rate of the 2026 Notes was 1.83%, which included the amortization of debt discounts over the term of the notes. We classified the fair value of the 2026 Notes as a Level 3 measurement due to the lack of observable market data over fair value inputs such as our stock price volatility over the term of the 2026 Notes and our cost of debt. The estimated fair value of the 2026 Notes as of December 31, 2025 w as $33.4 million, determined using a lattice model. During the three and six months ended June 30, 2026 and 2025, we recognized interest costs on the 2026 Notes as follows (in thousands):

Capped Call Transactions In connection with the repayment of the 2026 Notes at maturity, the Company's associated capped call transactions (the "2026 Capped Calls") expired in March 2026. Because the 2026 Capped Calls were classified as stockholders' equity and were not subject to remeasurement, there was no impact to the Company's Condensed Consolidated Statements of Operations upon expiration. Cash Collateral Agreement We maintain access to letters of credit under our Cash Collateral Agreement. Under this arrangement, cash collateral is required for all letters of credit, which is classified as restricted cash and presented within Prepaid expenses and other current assets on our Condensed Consolidated Balance Sheets. The amounts committed to letters of credit under the Cash Collateral Agreement as of June 30, 2026 and December 31, 2025 were $31.4 million and $32.8 million, respectively. There were no changes to the terms of the Cash Collateral Agreement during the periods presented. See Note 5, Supplemental Condensed Consolidated Balance Sheets and Statements of Operations Information, for additional information.
