Conversions

Based on the applicable conversion rate, the Toggle Convertible Notes plus any accrued and unpaid interest are convertible into cash, shares of the Company’s common stock or a combination thereof, at the Company’s election.

The initial conversion rates were adjusted on June 24, 2024 to be 3.812 and 22.8938 shares per $1,000 principal amount of the June 2022 Toggle Convertible Notes and April 2023 Toggle Convertible Notes, respectively, subject to customary anti-dilution adjustments in certain circumstances, which represent adjusted conversion prices of approximately $262.33 and $43.68 per share, respectively.

With respect to the June 2023 Toggle Convertible Notes, the conversion rate was adjusted on June 24, 2024, to be an amount equal to (a) 22.4809 divided by (b) a quotient, (i) the numerator of which is the sum of (x) the initial principal amount of the June 2023 Toggle Convertible Notes outstanding immediately prior to such conversion and (y) the aggregate amount capitalized related to PIK Interest issuances in respect of interest that came due on the June 2023 Toggle Convertible Notes and (ii) the denominator of which is the initial principal amount of the June 2023 Toggle Convertible Notes.

The Toggle Convertible Notes Indentures provide that prior to February 28, 2026, the Toggle Convertible Notes are convertible at the option of the holders only upon the occurrence of specified events and during certain periods, and will be convertible on or after February 28, 2026, at any time until the close of business on the second scheduled trading day immediately preceding the maturity date of the Toggle Convertible Notes.

Holders of the Toggle Convertible Notes have the right to convert all or a portion of their Toggle Convertible Notes prior to the close of business on the business day immediately preceding February 28, 2026 only under the following circumstances: (i) during any fiscal quarter commencing after the fiscal quarter ending on September 30, 2022 for the June 2022 Toggle Convertible Notes, during any fiscal quarter commencing after the fiscal quarter ending on June 30, 2023 for the April 2023 Toggle Convertible Notes, during any fiscal quarter commencing after the fiscal quarter ending on September 30, 2023 for the June 2023 Toggle Convertible Notes (and only during such fiscal quarter), if the last reported sale price of the Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price for the Toggle Convertible Notes on each applicable trading day; (ii) during the five business day period after any ten consecutive trading day period in which the trading price per $1,000 principal amount of the Toggle Convertible Notes for each trading day of that ten consecutive trading day period was less than 98% of the product of the last reported sale price of the Common Stock and the conversion rate of the Toggle Convertible Notes on each such trading day; (iii) if the Company calls

such Toggle Convertible Notes for redemption, at any time prior to the close of business on the second business day immediately preceding the redemption date; or (iv) upon the occurrence of specified corporate events.

Pursuant to the November Supplemental Indentures to June 2022 Notes and November Supplemental Indentures to June 2023 Notes, the June 2022 Toggle Convertible Notes and June 2023 Toggle Convertible Notes are convertible at the holder's option, at a reduced conversion price of $3.116 through January 31, 2025, conditioned on the holders purchasing at least $65.0 million of the Company's common stock. The holders completed $65.0 million of purchases in December 2024.

Redemption

Except with respect to the June 2023 Toggle Convertible Notes as described in the immediately succeeding paragraph, the Company may not redeem the Toggle Convertible Notes prior to June 1, 2025. The Company may redeem the Toggle Convertible Notes in whole or in part, at its option, on or after such date and prior to the 26th scheduled trading day immediately preceding the maturity date, for a cash purchase price equal to the aggregate principal amount of any Toggle Convertible Notes to be redeemed plus accrued and unpaid interest.

The June 2023 Toggle Convertible Notes provide for an additional optional redemption period from the initial issuance of such Toggle Convertible Notes through the first interest payment date of December 31, 2023, in whole and not in part for a cash purchase price equal to the aggregate principal amount of the June 2023 Toggle Convertible Notes.

In addition, following certain corporate events that occur prior to the maturity date or following issuance by the Company of a notice of redemption, in certain circumstances, the Company will increase the conversion rate for a holder who elects to convert its Toggle Convertible Notes (other than the June 2023 Toggle Convertible Notes) in connection with such a corporate event or who elects to convert any such Toggle Convertible Notes called for redemption during the related redemption period. Additionally, in the event of a fundamental change or a change in control transaction, holders of the Toggle Convertible Notes will have the right to require the Company to repurchase all or a portion of their Toggle Convertible Notes at a price equal to 100% of the capitalized principal amount of such Toggle Convertible Notes, in the case of a fundamental change, or 130% of the capitalized principal amount of such Toggle Convertible Notes, in the case of change in control transactions, in each case plus any accrued and unpaid interest to, but excluding, the repurchase date.

The Toggle Convertible Notes Indentures include restrictive covenants that, subject to specified exceptions, limit the ability of the Company and its subsidiaries to incur secured debt in excess of $500.0 million, incur other subsidiary guarantees, and sell equity interests of any subsidiary that guarantees the Toggle Convertible Notes. In addition, the Toggle Convertible Notes Indentures include customary terms and covenants, including certain events of default after which the holders may accelerate the maturity of the Toggle Convertible Notes issued thereunder and cause them to become due and payable immediately upon such acceleration.

Put Premium

In conjunction with the issuance of the June 2022 Toggle Convertible Notes, the Company executed the Put Premium which was determined to be an embedded derivative that met the criteria for bifurcation from the host. The total proceeds received were first allocated to the fair value of the bifurcated derivative asset, and the remaining proceeds allocated to the host resulting in an adjustment to the initial purchasers' debt discount.

The net proceeds from the sale of the June 2022 Toggle Convertible Notes were $183.2 million, net of initial purchasers' discounts and debt issuance costs. Unamortized debt discount and issuance costs were reported as a direct deduction from the face amount of the June 2022 Toggle Convertible Notes.

During the second quarter of 2023, the exchange of $100.0 million of June 2022 Toggle Convertible Notes for the issuance of $100.0 million of April 2023 Toggle Convertible Notes was determined to represent a substantial change in terms and extinguishment accounting was applied. The Company recognized a loss on debt extinguishment of $20.4 million for the year ended December 31, 2023. As part of the assessment of the exchange, the Company bifurcated the conversion features on the April 2023 Toggle Convertible Notes and recognized a derivative liability of $21.2 million as of the exchange date, resulting in an adjustment to the debt discount.

Additionally, during the second quarter of 2023, the execution of the Third Supplemental Indenture to June 2022 Notes and First Supplemental Indenture to April 2023 Notes were deemed modifications to the Toggle Convertible Notes outstanding

under the June 2022 Toggle Convertible Notes Indenture and April 2023 Toggle Convertible Notes Indenture, respectively, as the amended terms did not substantially change the terms of the respective notes. The consideration paid to the holders in the form of the issuance of the June 2023 Toggle Convertible Notes was recognized as an issuance cost upon modification and is amortized as an adjustment of interest expense over the remaining terms of the June 2022 Toggle Convertible Notes and April 2023 Toggle Convertible Notes.

During the year ended December 31, 2023, the holders of the April 2023 Toggle Convertible Notes exercised their conversion right for all the outstanding principal amount. The Company elected to settle the conversion with the issuance of 2,415,293 shares of common stock. The remaining unamortized discount was recognized in interest expense, net on the consolidated statements of operations due to the reclassification of the conversion feature to equity.

During the year ended December 31, 2024, holders of the June 2022 Toggle Convertible Notes converted $94.2 million aggregate principal amount of June 2022 Toggle Convertible Notes for the issuance of 30,215,497 shares, at the reduced conversion price of $3.116. The conversion was accounted for as an induced conversion in accordance with ASC 470-20, Debt with Conversion and Other Options.

On December 30, 2022, the Company entered into a securities purchase agreement (the “First Purchase Agreement”) with the investors named therein for the sale of up to $125.0 million in initial principal amount of unsecured senior convertible notes (the “First Purchase Agreement Notes”), in a registered direct offering. The First Purchase Agreement Notes are convertible into shares of the Company’s common stock, subject to certain conditions and limitations. The Company consummated an initial closing for the sale of $50.0 million in aggregate principal amount of First Purchase Agreement Notes on December 30, 2022 (the "Series A Notes").

The purchase price for the First Purchase Agreement Notes is $1,000 per $1,000 principal amount.

Each First Purchase Agreement Note accrued interest at a rate of 5% per annum, payable in arrears on the first calendar day of each calendar quarter, beginning April 1, 2023 for the Series A Notes, June 1, 2023 for the Series B-1 Notes and July 1, 2023 for the Series B-2 and Series B-3 Notes.

Each First Purchase Agreement Note issued pursuant to the First Purchase Agreement and Amended Purchase Agreements will have a maturity date of one year from issuance, which may be extended at the option of the noteholders in certain instances. Upon any conversion, redemption or other repayment of a First Purchase Agreement Note, a “make-whole” amount equal to the amount of additional interest that would accrue under such First Purchase Agreement Note at the interest rate then in effect assuming that the outstanding principal of such First Purchase Agreement Notes remained outstanding through and including the maturity date of such First Purchase Agreement Note.

At any time on or after January 9, 2023, all or any portion of the principal amount of each First Purchase Agreement Note, plus accrued and unpaid interest, any make-whole amount and any late charges thereon (the “Conversion Amount”), is convertible at any time, in whole or in part, at the noteholder’s option, into shares of the Company's common stock at a conversion price per share (the “Conversion Price”) equal to the lower of (i) the applicable “reference price”, subject to certain adjustments (the “Reference Price”), (ii) the greater of (x) the applicable “floor price” (the “Floor Price”) and (y) the volume weighted average price (“VWAP”) of the Common Stock as of the conversion date, and (iii) the greater of (x) the Floor Price, and as elected by the converting noteholder, (y) either (X) depending on the delivery time of the applicable conversion notice,

(1) the VWAP as of the applicable conversion date or (2) the VWAP immediately prior to the applicable conversion date and (Y) 95% of the average VWAP for the three trading days commencing on, and including, the applicable conversion date, subject to adjustment in accordance with the terms of the Notes.

At any time during an Event of Default Redemption Right Period (as defined below), a noteholder may alternatively elect to convert all or any portion of the First Purchase Agreement Notes at an alternate conversion rate (the “Alternate Conversion Rate”) equal to the quotient of (i) 115% of the Conversion Amount divided by (ii) the Conversion Price.

Upon a change of control, a noteholder may, subject to certain exceptions, require the Company to redeem all, or any portion, of the First Purchase Agreement Notes in cash at a price equal to 115% of the greatest of: (i) the Conversion Amount, (ii) the product of (x) the Conversion Amount and (y) the quotient of (I) the greatest closing sale price of the common stock during the period beginning on the date immediately preceding the earlier to occur of (1) the consummation of a change of control and (2) the public announcement of such change of control, and ending on the date the noteholder notifies the Company of its exercise of its right to redeem pursuant to the change of control divided by (II) the Conversion Price, and (iii) the product of (x) the Conversion Amount and (y) the quotient of (I) the aggregate consideration per share of common stock to be paid to the holders of the Common Stock upon consummation of such change of control divided by (II) the Conversion Price.

At any time an “Equity Conditions Failure” (as defined in the First Purchase Agreement Notes) exists at the time of consummation of certain “Subsequent Placements” (as defined in the First Purchase Agreement), the noteholders have the right, subject to certain exceptions, to require that the Company redeem all, or any portion, of the Conversion Amount of the Notes not in excess of the gross proceeds of such Subsequent Placement at a redemption price of 100% of the Conversion Amount to be redeemed. If the noteholder is participating in such Subsequent Placement, the noteholder may require the Company to apply all, or any part, of any amounts that would otherwise be payable to the noteholder in such redemption, on a dollar-for-dollar basis, against the purchase price of the securities to be purchased by the noteholder in such Subsequent Placement.

A noteholder will not have the right to convert any portion of the First Purchase Agreement Notes, to the extent that, after giving effect to such conversion, the noteholder (together with certain of its affiliates and other related parties) would beneficially own in excess of 4.99% of the shares of common stock outstanding immediately after giving effect to such conversion (the “Maximum Percentage”). The noteholder may from time to time increase the Maximum Percentage to 9.99%, provided that any such increase will not be effective until the 61st day after delivery of a notice to the Company of such increase.

The First Purchase Agreement Notes provide for certain Events of Default, including certain types of bankruptcy or insolvency events of default involving the Company after which the First Purchase Agreement Notes become automatically due and payable. At any time after the earlier of (x) a noteholder’s receipt of a required notice of an event of default, and (y) the noteholder becoming aware of an event of default, and ending on the twentieth trading day after the later of (I) the date such event of default is cured, and (II) the investor’s receipt of an event of default notice from the Company (such period, the “Event of Default Redemption Rights Period”), the noteholder may require the Company to redeem, subject to certain exceptions, all or any portion of its Notes at a price equal to 115% of the greater of (i) the Conversion Amount and (ii) the product of the Alternate Conversion Rate and the greatest closing sale price of the common stock on any trading day during the period commencing on the date immediately preceding such Event of Default and ending on the trading day immediately prior to the date the Company makes the entire redemption payment.

The Company will be subject to certain customary affirmative and negative covenants regarding the rank of the First Purchase Agreement Notes, the incurrence of certain indebtedness, the repayment of certain indebtedness, transactions with affiliates, and restrictions on certain issuance of securities, among other customary matters.

Interest was not paid in cash but was capitalized on each interest payment date by adding the accrued interest to the then outstanding principal of the Notes. Each Third Purchase Agreement Note issued pursuant to the Third Purchase Agreement had a maturity date of one year from issuance, which may be extended at the option of the noteholders in certain instances. Upon any conversion, redemption or other repayment of a Third Purchase Agreement Note, a “make-whole” amount equal to the amount of additional interest that would accrue under such Third Purchase Agreement Note at the interest rate then in effect assuming that the outstanding principal of such Third Purchase Agreement Notes remained outstanding through and including the maturity date of such Third Purchase Agreement Note.

8.25% Convertible Notes

On December 12, 2023, the Company consummated the sale and issuance of $175.0 million aggregate principal amount of the 8.25% Green Convertible Senior Notes due 2026. The 8.25% Convertible Notes are senior, unsecured obligations of the Company.

The 8.25% Convertible Notes accrue interest at a rate of 8.25% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2024. The 8.25% Convertible Notes will mature on December 15, 2026, unless earlier repurchased, redeemed or converted. At any time before the close of business on the second scheduled trading day immediately before the maturity date, noteholders may convert their 8.25% Convertible Notes at their option. The Company will settle conversions by delivering (i) shares of the Company’s common stock (together, if applicable, with cash in lieu of any fractional share), at the then-applicable conversion rate; and (ii) a cash amount representing the present value of remaining scheduled coupon payments on the converted notes discounted at United States treasuries plus 50 basis points (the “Coupon Make-Whole Premium”). The conversion rate was adjusted on June 24, 2024, to be 37.0370 shares of common stock per $1,000 principal amount of 8.25% Convertible Notes, which represents an adjusted conversion price of approximately $27.00 per share of common stock. The conversion rate and conversion price are subject to customary adjustments upon the occurrence of certain events. In addition, if certain corporate events that constitute a make-whole fundamental change occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time.

The 8.25% Convertible Notes will be redeemable, in whole or in part (subject to certain limitations described below), at the Company’s option at any time, and from time to time, on or after December 15, 2025 and before the maturity date, but only if the last reported sale price per share of the Company’s common stock exceeds 175% of the conversion price on each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice. However, the Company may not redeem less than all of the outstanding 8.25% Convertible Notes unless at least $100.0 million aggregate principal amount of 8.25% Convertible Notes are outstanding and not called for redemption as of the time the Company sends the related redemption notice. The redemption price will be a cash amount equal to the principal amount of the 8.25% Convertible Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

If certain corporate events that constitute a fundamental change occur prior to the maturity date, then, subject to a limited exception for certain cash mergers, noteholders may require the Company to repurchase their 8.25% Convertible Notes at a cash repurchase price equal to the principal amount of the 8.25% Convertible Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. The definition of fundamental change includes

certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s common stock.

The 8.25% Convertible Notes have customary provisions relating to the occurrence of events of default, which include the following: (i) certain payment defaults on the 8.25% Convertible Notes (which, in the case of a default in the payment of interest on the 8.25% Convertible Notes, will be subject to a 30-day cure period); (ii) the Company’s failure to send certain notices under the Indenture within specified periods of time; (iii) the Company’s failure to comply with certain covenants in the Indenture relating to the Company’s ability to consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, to another person; (iv) a default by the Company in its other obligations or agreements under the Indenture or the Notes if such default is not cured or waived within 60 days after notice is given in accordance with the Indenture; (v) certain payment defaults or other defaults that result in the acceleration prior to stated maturity of indebtedness for borrowed money of the Company or any of its significant subsidiaries of at least $30,000,000 are not cured, waived, rescinded or discharged, as applicable, within 30 days after notice is given in accordance with the Indenture; (vi) the rendering of certain judgments against the Company or any of its significant subsidiaries for the payment of at least $30,000,000 (excluding any amounts covered by insurance), where such judgments are not discharged or stayed within 60 days after date on which the right to appeal has expired or on which all rights to appeal have been extinguished; and (vii) certain events of bankruptcy, insolvency and reorganization involving the Company or any of its significant subsidiaries.

If an event of default involving bankruptcy, insolvency or reorganization events with respect to the Company (and not solely with respect to a significant subsidiary of the Company) occurs, then the principal amount of, and all accrued and unpaid interest and Coupon Make-Whole Premium, if any, on, all of the 8.25% Convertible Notes then outstanding will immediately become due and payable without any further action or notice by any person. If any other event of default occurs and is continuing, then, the Trustee, by notice to the Company, or noteholders of at least 25% of the aggregate principal amount of 8.25% Convertible Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid interest and Coupon Make-Whole Premium, if any, on, all of the 8.25% Convertible Notes then outstanding to become due and payable immediately. However, notwithstanding the foregoing, the Company may elect, at its option, that the sole remedy for an event of default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture consists exclusively of the right of the noteholders to receive during the continuance of such event of default special interest on the 8.25% Convertible Notes for up to 180 days at a specified rate per annum of 0.25% for the first 90 days and 0.50% from the 91st day until the 180th day, in each case, on the principal amount of the 8.25% Convertible Notes.

The conversion features embedded to the 8.25% Convertible Notes met the criteria to be separated from the host contract and recognized separately at fair value, see Note 2, Summary of Significant Accounting Policies. The total proceeds received were first allocated to the fair value of the bifurcated derivative liability, and the remaining proceeds allocated to the host resulting in an adjustment to the initial purchasers' debt discount.

The Company recognized $122.1 million upon issuance of the 8.25% Convertible Notes, net of initial purchasers' discounts of $47.3 million and debt issuance costs of $5.6 million. Unamortized debt discount and issuance costs were reported as a direct deduction from the face amount of the 8.25% Convertible Notes.

Financing Obligations

On May 10, 2022 (the "Sale Date"), the Company entered into a sale agreement (the "Sale Agreement"), pursuant to which the Company sold the land and property related to the Company's headquarters in Phoenix, Arizona for a purchase price of $52.5 million. As of the Sale Date, $13.1 million was withheld from the proceeds received related to portions of the headquarters undergoing construction. The Company received the remaining proceeds throughout the completion of construction pursuant to the terms of the Sale Agreement. Concurrent with the sale, the Company entered into a lease agreement (the "Lease Agreement"), whereby the Company leased back the land and property related to the headquarters for an initial term of 20 years with four extension options for 7 years each. As of the Sale Date, the Company considered one extension option reasonably certain of being exercised.

The buyer is not considered to have obtained control of the headquarters because the lease is classified as a finance lease. Accordingly, the sale of the headquarters is not recognized and the property and land continue to be recognized on the Company's consolidated balance sheets. Rent payments under the terms of the Lease Agreement are allocated between interest expense and principal repayments using the effective interest method. Additionally, debt issuance costs are amortized to interest expense over the lease term.

As of December 31, 2024 and 2023 the financing obligation for the headquarters was $51.5 million and $51.5 million, respectively, on the Company's consolidated balance sheets. For the years ended December 31, 2024 and 2023, the Company recognized $3.6 million of interest expense related to interest on the financing obligation and amortization of debt issuance costs.

Concurrent with the sale, the Company entered into a lease agreement (the "Land Lease Agreement"), whereby the Company leased back the land for an initial term of 99 years. The Land Lease Agreement grants the Company an option to repurchase the land upon the fiftieth (50th) anniversary of the Land Sale Date for a price equal to the greater of the fair market value, or 300% of the purchase price. As of the Land Sale Date, the Company considered the purchase option reasonably certain of being exercised.

The buyer is not considered to have obtained control of the land because the lease is classified as a finance lease. Accordingly, the sale of the land in Coolidge, Arizona is not recognized and the land continues to be recognized on the Company's consolidated balance sheets. As of the Land Sale Date, the Company recorded $49.4 million as a financing obligation on the Company's consolidated balance sheets representing proceeds received net of debt issuance costs of $1.0 million. Rent payments under the terms of the Land Lease Agreement will be allocated between interest expense and principal repayments using the effective interest method. Additionally, debt issuance costs will be amortized to interest expense over the lease term.

As of December 31, 2024 and 2023 the financing obligation for the land was $50.9 million and $49.9 million, respectively, on the Company's consolidated balance sheets. For the years ended December 31, 2024 and 2023, the Company recognized $5.2 million and $2.6 million, respectively, of interest expense related to interest on the financing obligation and amortization of debt issuance costs.

The Second Collateralized Note carries a 60 month term and is payable in 60 equal monthly installments due in arrears.

For the years ended December 31, 2024 and 2023, the Company recognized immaterial amounts of interest expense on the Second Collateralized Note.
