2026 Convertible Notes

On April 21, 2020, the Company sold $500.0 million aggregate principal amount of 1.75% convertible senior notes due May 1, 2026 to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the Securities Act) and an additional $75.0 million aggregate principal amount of such notes pursuant to the exercise in full of the over-allotment options of the underwriters (the 2026 Notes). The total net proceeds from the 2026 Notes offering was approximately $561.4 million.

The Company used approximately $144.3 million of the net proceeds from the sale of the 2026 Notes in April 2020 to repurchase approximately $150.2 million aggregate principal amount of the then outstanding 0.875% convertible senior notes due September 1, 2023, including approximately $0.2 million of accrued interest on such notes, in privately negotiated transactions.

2028 Convertible Notes

On February 3, 2022, the Company sold $650.0 million aggregate principal amount of 0.25% convertible senior notes due February 15, 2028 to qualified institutional buyers pursuant to Rule 144A under the Securities Act and an additional $100.0 million aggregate principal amount of such notes pursuant to the exercise in full of the over-allotment options of the underwriters (the 2028 Notes). The total net proceeds from the 2028 Notes offering was approximately $732.3 million.

The Company used approximately $108.2 million of the net proceeds from the 2028 Notes to fund the cost of entering into capped call transactions, as described below.

Capped Call Transactions in relation to the 2028 Notes

On January 31, 2022, in connection with the pricing of the 2028 Notes, the Company entered into privately negotiated capped call transactions with certain of the initial purchasers or affiliates thereof (the 2028 Notes Capped Call Counterparties). In connection with the exercise by the initial purchasers of their option to purchase additional notes, the Company entered into additional privately negotiated capped call transactions (such transactions, collectively, the 2028 Notes Capped Call Transactions) with each of the 2028 Notes Capped Call Counterparties. The 2028 Notes Capped Call Transactions initially cover, subject to customary anti-dilution adjustments, the aggregate number of shares of the Company’s common stock that initially underlie the 2028 Notes. The 2028 Notes Capped Call Transactions are expected generally to reduce the potential dilutive effect on the common stock upon any conversion of 2028 Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of converted 2028 Notes, as the case may be, with such reduction and/or offset subject to a cap which initially is $212.04 per share, representing a premium of 125% over the last reported sale price per share of the Company's common stock on January 31, 2022, subject to certain adjustments under the terms of the 2028 Notes Capped Call Transactions.

The 2028 Notes Capped Call Transactions are separate transactions entered into by the Company with each of the 2028 Notes Capped Call Counterparties, are not part of the terms of the 2028 Notes, and do not affect any holder’s rights under the 2028 Notes. Holders of the 2028 Notes do not have any rights with respect to the 2028 Notes Capped Call Transactions.

2029 Convertible Notes

On November 21, 2022, the Company sold $1,525.0 million aggregate principal amount of 1.875% convertible senior notes due December 1, 2029 to qualified institutional buyers pursuant to Rule 144A under the Securities Act and an additional $225.0 million aggregate principal amount of such notes pursuant to the exercise in full of the over-allotment options of the underwriters (the 2029 Notes). The total net proceeds from the 2029 Notes offering was approximately $1,718.6 million.

The Company used approximately $273.9 million of the net proceeds from the 2029 Notes to fund the cost of entering into capped call transactions, as described below.

Capped Call Transactions in relation to the 2029 Notes

On November 16, 2022, in connection with the pricing of the 2029 Notes, the Company entered into privately negotiated capped call transactions with certain of the initial purchasers or their affiliates and another financial institution (the 2029 Notes Capped Call Counterparties). In connection with the exercise by the initial purchasers of their option to purchase additional notes, the Company entered into additional privately negotiated capped call transactions (such transactions, collectively, the 2029 Notes Capped Call Transactions) with each of the 2029 Notes Capped Call Counterparties. The 2029 Notes Capped Call Transactions initially cover, subject to customary anti-dilution adjustments, the aggregate number of shares of the Company’s common stock that initially underlie the 2029 Notes. The 2029 Notes Capped Call Transactions are expected generally to reduce the potential dilutive effect on the common stock upon any conversion of 2029 Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of converted 2029 Notes, as the case may be, with such reduction and/or offset subject to a cap which initially is $202.538 per share, representing a premium of 130% over the last reported sale price per share of our common stock on November 16, 2022, subject to certain adjustments under the terms of the 2029 Notes Capped Call Transactions.

The 2029 Notes Capped Call Transactions are separate transactions entered into by the Company with each of the 2029 Notes Capped Call Counterparties, are not part of the terms of the 2029 Notes, and do not affect any holder’s rights under the 2029 Notes. Holders of the 2029 Notes do not have any rights with respect to the 2029 Notes Capped Call Transactions.

Accounting for the 2026 Notes, 2028 Notes and 2029 Notes

Debt issuance costs for the 2026 Notes, 2028 Notes and 2029 Notes are amortized to interest expense over their respective terms at an effective annual interest rate of 2.2%, 0.6% and 2.1%, respectively.

The 2026 Notes, 2028 Notes and 2029 Notes (the Outstanding Convertible Notes) are equal in right of payment to any of the Company’s unsecured indebtedness; senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated in right of payment to the Outstanding Convertible Notes; effectively subordinated in right of payment of any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally subordinated to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries.

The net carrying amount of the liability component of the Outstanding Convertible Notes is as follows:

(in millions of U.S. Dollars)	March 31, 2024	June 25, 2023
Principal	$3,075.0	$3,075.0
Unamortized discount and issuance costs	(42.4)	(49.4)
Net carrying amount	$3,032.6	$3,025.6

The last reported sale price of the Company's common stock was not greater than or equal to 130% of the applicable conversion price for any of the Outstanding Convertible Notes for at least 20 trading days in the 30 consecutive trading days ended on March 31, 2024. As a result, none of the Outstanding Convertible Notes are convertible at the option of the holders through March 31, 2024.

2030 Senior Notes

On June 23, 2023 (the Issue Date), the Company sold $1,250 million aggregate principal amount of senior secured notes due 2030 (the 2030 Senior Notes). The total net proceeds from the 2030 Senior Notes was approximately $1,149.3 million. The total net proceeds are net of debt issuance costs and an original issue discount of $50.0 million.

The 2030 Senior Notes bear interest (i) during the first three years after the Issue Date at a rate of 9.875% per annum, (ii) during the fourth year after the Issue Date at a rate of 10.875% per annum, and (iii) at all times thereafter, 11.875% per annum, and

will mature on the earlier of (x) June 23, 2030 and (y) September 1, 2029, if more than $175.0 million in aggregate principal amount of the 2029 Notes remain outstanding on such date. Subject to the fulfillment of certain conditions precedent, the Company may, at its discretion, issue and sell additional 2030 Senior Notes in an amount not to exceed $750.0 million.

The Indenture related to the 2030 Senior Notes (the 2030 Senior Notes Indenture) requires the Company to make an offer to repurchase the 2030 Senior Notes with 100% of the net cash proceeds of (x) certain core asset sales and casualty events and (y) certain non-core asset sales and casualty events, in either case in excess of $25.0 million since the Issue Date, subject to the ability to (so long as no default or event of default exists under the 2030 Senior Notes Indenture) reinvest the proceeds of such casualty events and asset sales (other than the proceeds of sales of certain core assets of the Company), at a price equal to the lesser of (i) 109.875% of the principal amount of the 2030 Senior Notes being repurchased and (ii) if such disposition or casualty event occurred (x) during the fourth year after the Issue Date, 109.40625% of the principal amount of such 2030 Senior Notes being repurchased, (y) during the fifth year after the Issue Date, 104.9375% of the principal amount of such 2030 Senior Notes being repurchased and (z) during and after the sixth year after the Issue Date, 100% of the principal amount of such 2030 Senior Notes being repurchased (this clause (ii), the Applicable Redemption Price). The Company is also required to offer to repurchase the 2030 Senior Notes upon a change in control, at a price equal to, (i) if the change of control occurs during the first three years after the Issue Date, a customary make-whole redemption price minus 3.00% of the principal amount of Senior Notes being purchased and (ii) if such change of control occurs after the third anniversary of the Issue Date, the Applicable Redemption Price. The Company may prepay the 2030 Senior Notes at any time, subject to: (i) if the prepayment occurs prior to the third anniversary of the Issue Date, by paying a customary make-whole premium and (ii) if the prepayment occurs on or after the third anniversary of the Issue Date, by paying the Applicable Redemption Price. Further, the Company has the right, prior to the third anniversary of the Issue Date, to make an optional redemption of up to 35% of the aggregate principal amount of the 2030 Senior Notes with the proceeds of qualified equity issuances, at a redemption price equal to 109.875%.

The 2030 Senior Notes Indenture contains certain customary affirmative covenants, negative covenants and events of default, including a liquidity maintenance financial covenant requiring the Company to have an aggregate amount of unrestricted cash and cash equivalents maintained in accounts over which the trustee and collateral agent has been granted a perfected first lien security interest of at least $500.0 million as of the last day of any calendar month (the Liquidity Covenant). Upon the Company achieving 30% utilization at its silicon carbide device fabrication facility in Marcy, New York and generating at least $240.0 million of revenue from the Company's Power product line, that are manufactured or produced on wafers that are fabricated at the Marcy, New York facility (the MVF Products), in each case over a six-month period, the level of the Liquidity Covenant shall be permanently reduced to $325.0 million. Upon the Company achieving 50% utilization at its Marcy, New York facility and generating at least $450.0 million of revenue from MVF Products, in each case over a six-month period, the Liquidity Covenant will be permanently reduced to zero.

As of March 31, 2024, the Company was in compliance with all covenants relating to the 2030 Senior Notes.

The 2030 Senior Notes are superior in right of payment to the Company's unsecured indebtedness to the extent of the collateral securing the 2030 Senior Notes. Beyond the value of the collateral securing the 2030 Notes, the 2026 Notes, 2028 Notes, 2029 Notes and 2030 Senior Notes (the Corporate Debt Holdings) are equal in right of payment to any of the Company’s unsecured indebtedness; senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated in right of payment to the Corporate Debt Holdings; effectively subordinated in right of payment of any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally subordinated to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries.

Debt issuance costs in relation to the 2030 Senior Notes were accounted for as a reduction of the principal balance and, along with the original issue discount, will be amortized over the term of the 2030 Senior Notes at an effective interest rate of 12.4%.

CRD Agreement Deposits

In July 2023, the Company entered into an Unsecured Customer Refundable Deposit Agreement (the CRD Agreement) with a customer, pursuant to which the customer will provide the Company up to $2 billion in unsecured deposits. Under the CRD Agreement, the Company received an initial deposit of $1 billion with the option to receive additional deposits up to an additional $1 billion at the Company's request, subject to certain conditions during the 2024 calendar year. On February 27, 2024, the Company received an additional deposit of $500 million (the second draw). Unless previously terminated in accordance with its terms, the CRD Agreement will mature on July 5, 2033, and the amount of the deposits, together with accrued and unpaid interest, will be required to be repaid to the customer at such time.

The deposits under the CRD Agreement bear interest, payable on a semi-annual basis, at a base rate of 6% per annum, with the potential for an increased variable rate of either 10% or 15% in connection with any inability of the Company to satisfy supply targets under a ten-year wafer supply agreement with the same customer. The Company may voluntarily prepay the deposits, in whole or in part, at any time at a price equal to 106% of the principal amount of the deposits prepaid. Upon the occurrence of a change of control, the customer may require the Company to prepay the deposits in whole at a variable prepayment price depending on the day of prepayment.

Debt issuance costs for the CRD Agreement related to the full deposit capacity under the agreement. A portion of the debt issuance costs were accounted for on a pro rata basis as a reduction of the principal balance for the initial deposit and the second draw, and will be amortized over the term of the deposit at an effective interest rate of 6.3%. During the third quarter of fiscal 2024, the debt issuance costs allocated to the second draw were $11.4 million and these costs were reclassified from prepaid expense and recorded as a reduction of principal related to the additional deposit received. The remaining debt issuance costs of approximately $11.4 million are recorded as a prepaid expense and will be recorded as a reduction of the principal balance, on a pro rata basis, if additional deposits are drawn under the CRD Agreement.

The CRD Agreement contains certain customary affirmative covenants, negative covenants and events of default. As of March 31, 2024, the Company was in compliance with all covenants related to this agreement.

The net carrying amount of the liability component of the 2030 Senior Notes and the deposits under the CRD Agreement is as follows:

(in millions of U.S. Dollars)	March 31, 2024	June 25, 2023
