Commitment Letter with the U.S. Department of War

On October 7, 2026, Wolfspeed, Inc. (the "Company," "we," "us," or "our") announced that it had entered into a conditional commitment letter (the "Commitment Letter") with the U.S. Department of War (the "DoW"), acting by and through its Office of Strategic Capital (the "OSC"), contemplating a senior secured delayed draw term loan facility in an aggregate principal amount up to $1.5 billion (the "Facility"), consisting of up to four tranches in the amount of $600 million for the initial tranche and $900 million for the remaining tranches, ranging from $200 million to $400 million. As set forth below, entry into the Facility on the contemplated terms (or any terms) is subject to substantial conditions, including due diligence and the negotiation of definitive transaction documentation ("Definitive Agreements"). While subject to due diligence and the negotiation of Definitive Agreements, among other conditions, the Facility is currently expected to have a 30-year maturity and a 36-month commitment period during which the Company can draw on the various tranches (should the significant conditions, which shall be finalized in the definitive transaction documentation, for such draws be met). Proceeds of the Facility would be used (a) on the closing date with the proceeds of the initial tranche, to refinance in full the Company's outstanding New Senior Secured Notes and to pay transaction fees and expenses, subject to the Company entering into the Project Undertaking (as defined below), which shall require the Company to complete the Project (as defined below) and (b) thereafter with the proceeds of the remaining tranches, to fund other expenditures in furtherance of the Project. The transactions contemplated by the conditional Commitment Letter are referred to herein collectively as the "Expected U.S. Government Transaction".

No assurances can be made that the Company will successfully negotiate and enter into Definitive Agreements or obtain funding in the Expected U.S. Government Transaction with the DoW or the OSC, or that the Expected U.S. Government Transaction with the DoW or the OSC will be consummated on the terms currently contemplated, or at all. The execution of the Definitive Agreements and consummation of the Expected U.S. Government Transaction are subject to substantial due diligence and numerous conditions, and subject to negotiation and finalization of agreements, significant closing conditions, governmental authorizations and approvals, appropriations and required third party-consents.

The interest rate on the Facility is expected to be comparable to the U.S. Treasury rate of a similar maturity plus a risk premium that will be determined on a final basis in the Definitive Agreements. The risk premium is provisionally contemplated to be between 1.25% and 1.75% but is subject to diligence and negotiation of the Definitive Agreements (it being understood that the final risk premium will be in the Definitive Agreements). As contemplated as of October 7, 2026, the interest will be payable on a quarterly basis; provided that, for the first five years following the effective date of the Facility (the "Interest Only Period") and so long as no event of default has occurred, interest may be capitalized to principal. Following the Interest Only Period, interest and principal will be payable in cash quarterly and will amortize on a 25-year straight-line basis.

Entry into Definitive Agreements for the Expected U.S. Government Transaction and obtaining the conditional financing discussed above is subject to substantial conditions, including, without limitation: (a) the DoW obtaining receipt of authorizations or reauthorizations from relevant governmental authorities by the United States Congress and the availability of appropriations and concurrence of the Office of Management and Budget, each of which is beyond the control of the Company, (b) the Company using commercially reasonable efforts to equitize a substantial majority of the aggregate principal amount of the Company's outstanding convertible notes, (c) entrance into an undertaking by the Company and its subsidiary guarantors, secured by the assets of the Company and its subsidiary guarantors, to complete, collectively, (i) the buildout of domestic silicon carbide ("SiC") wafer and power device production, (ii) the establishment of domestic low voltage and/or high voltage gallium nitride ("GaN") production, or the onshoring of GaN production, (iii) the investment in GaN-on-SiC radio frequency epitaxial wafer technology, and (iv) the development of domestic radiation hardening capabilities on terms to be agreed (collectively, the "Project" and the Company's undertaking to complete the Project, the "Project Undertaking"), (d) entry into customary financing documentation, (e) delivery of a definitive budget covering the Company, its subsidiary guarantors and the Project, (f) completion of OSC's business, financial, legal, tax, environmental, collateral, technical, Project and other due diligence to the satisfaction of OSC in its sole discretion, (g) execution of one or more letters of intent or definitive offtake agreements, on terms acceptable to the OSC, and (h) satisfactory amendments or waivers to agreements governing certain of the Company's existing indebtedness.

In addition, the conditional obligation of the OSC to fund each tranche will be subject to the satisfaction of certain conditions, including, without limitation: (1) the Company's contribution of Qualifying Sources (as defined below) received after June 28, 2026 in an aggregate amount of at least $750 million or such other amount determined by the OSC during its due diligence (the "Minimum Contribution"), which may be funded on a tranche-by-tranche basis in an amount no less than (a) with respect to the initial tranche, $150 million, and (b) with respect to the remaining tranches, an aggregate of $600 million, (2) with respect to the funding of the tranches following the initial tranche, the completion of due diligence to the satisfaction of OSC in its sole discretion, (3) with respect to the funding of the tranches following the initial tranche, entering into certain commercial arrangements, including offtake agreements, on terms acceptable to the OSC, (4) with respect to the funding of certain tranches following the initial tranche, the Company's use of commercially reasonable efforts to equitize at least a substantial majority of the aggregate principal amount of convertible notes outstanding as of June 28, 2026, if and to the extent such target has not already been equitized and (5) demonstration of pro forma compliance with applicable financial covenants, including a loan-to-value covenant, both immediately before and after giving effect to the applicable disbursement. As used herein, "Qualifying Sources" means (a) the proceeds from the issuance of common equity, preferred equity (acceptable to the OSC and together with common equity, "Qualifying Equity"), or qualifying equity-linked instruments issued to third parties, unaffiliated with the U.S. government, (b) Qualifying Equity issued to third parties unaffiliated with the U.S. government as all or a portion of the consideration for an acquisition or other transaction funded in whole or in part with the proceeds of the applicable tranche, valued at the fair market value of such Qualifying Equity as of the date of issuance, (c) excess cash (as determined by the OSC), (d) the face value of convertible indebtedness converted or equitized into equity, and (e) other items subject to the discretion of the OSC; provided, that the Minimum Contribution in respect of the initial tranche must consist of proceeds from the issuance of Qualifying Equity issued to third parties unaffiliated with the U.S. government (i) in an amount equal to $50 million that must be raised prior to the effective date of the Facility and (ii) in an amount equal to $100 million that may be raised after the effective date of the Facility and prior to the funding of the second tranche, and the remaining $600 million of the Minimum Contribution may be satisfied through a combination of Qualifying Equity, the Qualifying Source described in clause (b) above and, subject to the discretion of OSC (and compliance with the loan-to-value covenant on a pro forma basis), any combination of the other Qualifying Sources described in clauses (a) through (e) above. All Qualifying Sources received after June 28, 2026 are expected to count towards the satisfaction of the Minimum Contribution.

The Definitive Agreements would include certain representations, warranties, covenants (including financial covenants), mandatory prepayments and events of default usual and customary for facilities of this type, which include (a) certain requirements and restrictions applicable through the later of (x) the repayment in full of all outstanding loans and termination of all commitments under the Facility and (y) the maturity date, which requirements and restrictions include restrictions on changes of control with parties other than permitted persons, requirements that the majority of the board of directors consist of U.S. citizens and that the chief executive officer be a national of a permitted jurisdiction, requirements to maintain the Company's principal headquarters in the United States, and the grant to the DoW of certain rights on products or services related to the Project and (b) the right of the OSC to designate a non-voting board observer to attend meetings of the Company's board of directors (and committees thereof).

As an additional condition to entry into Definitive Agreements for the Expected U.S. Government Transaction, the Company would be required to issue warrants to the DoW pro rata as and when each tranche is funded to purchase (a) 5% of the outstanding equity of the Company with an exercise price based on a mutually agreed volume-weighted average price ("VWAP") of the Company's common stock and (b) 2.5% of the outstanding equity of the Company with an exercise price based on a mutually agreed VWAP of the Company's common stock (such percentages in each case calculated on a fully-diluted basis as of the effective date of the Facility, including the exercise of the warrants but excluding the issuance of common stock to satisfy the Minimum Contribution, subject to finalization in the definitive documents). The warrants are anticipated to be exercisable at any time and from time to time for a term of ten years. Any unexercised warrants will automatically self-exercise on a cashless basis immediately prior to expiration to the extent such warrants are in the money. The definitive warrant instrument will include customary terms for transactions of this type, including cashless exercise, registration rights and structural dilution protection, along with repurchase rights in the event the Facility is prepaid in full. For additional information, see "Risk Factors" in Part II, Item 1A of this Quarterly Report.

On June 30, 2025, the "Petition Date"), Wolfspeed, Inc. (the Company "we," "us," or "our") and its wholly owned subsidiary, Wolfspeed Texas LLC, (together with the Company, the "Debtors"), voluntarily filed petitions (the "Chapter 11 Cases") for relief under Chapter 11 of the United States Bankruptcy Code (the Bankruptcy Code in the United States Bankruptcy Court for the Southern District of Texas, Houston Division (the "Bankruptcy Court") to implement a prepackaged Chapter 11 plan of reorganization (the "Plan"). The Chapter 11 Cases were administered jointly under the caption In re Wolfspeed, Inc., et al , case number 25-90163 (CML).

The Chapter 11 filings, including the Plan and the Disclosure Statement filed on June 30, 2025, were intended to facilitate a comprehensive balance sheet restructuring pursuant to the a Restructuring Support Agreement executed on June 22, 2025, with key stakeholders, including (i) holders of more than 97% of the Company's Senior Secured Notes due 2030, (ii) holders of more than 67% of the Company's outstanding 1.75% Convertible Senior Notes due 2026, 0.25% Convertible Senior Notes due 2028, and 1.875% Convertible Senior Notes due 2029, and (iii) Renesas Electronics America Inc. ("Renesas").

On September 8, 2025, the Bankruptcy Court entered the Order (I) Approving the Disclosure Statement, (II) Confirming Joint Prepackaged Chapter 11 Plan of Reorganization of Wolfspeed, Inc. and Its Debtor Affiliate, and (III) Approving Entry into the Backstop Agreement (Docket No. 285), (the "Confirmation Order"), which, among other things, confirmed the Plan.

On September 29, 2025 (the "Effective Date"), the Company emerged from the Chapter 11 Cases upon all the conditions to the effectiveness of the Plan being satisfied or waived and the Plan becoming effective. Refer to Note 2, 1, "Basis of Presentation and Summary of Significant New Accounting Policies" and Note 3, "Emergence from Voluntary Reorganization under Chapter 11," Standards" to our consolidated financial statements in Part II, I, Item 8 1 of this Annual Quarterly Report for additional information.

Upon the Company's emergence from the Chapter 11 Cases, the Company adopted fresh start accounting, which resulted in a new basis of accounting and the Company becoming a new entity for financial reporting purposes. As a result of the application of fresh start accounting and the effects of the implementation of the Plan, the Company's consolidated financial statements after the Effective Date are not comparable with the consolidated financial statements on or before that date. Refer to Note 4, "Fresh Start Accounting," to our consolidated financial statements in Part II, Item 8 of this Annual Report for additional information.

• Overall Demand for Products and Applications Using Our Wolfspeed Materials and Devices . Our potential for growth depends significantly on the continued adoption of silicon carbide and gallium nitride ("GaN") materials and device products in the power market, and our ability to adapt to evolving competitive dynamics to retain and grow market share for these applications. We have been experiencing softening demand for some of our products and continued price pressure in certain applications. We continue to expect increased mid- and long-term demand growth, however the timing and extent of these increases remains uncertain. We also continue to explore opportunities to expand adoption of our products in new and growing industries, such as AI data centers, grid modernization and renewable energy and storage, as well as aerospace and defense.

Net sales for the Successor period ended June 28, 2026 and Predecessor period ended September 29, 2025 as compared to fiscal 2025 were down 12% primarily driven by the following:

• Net sales of our Power Product offerings increased due to stronger demand for our industrial applications products, partially attributable to the end-of-life buys associated with the closure of our Durham Fab, and growth in emerging applications for silicon carbide devices such as AI and data center applications, partially offset by a reduction in automotive demand and continued pricing pressure during the year.

Gross Profit and Gross Margin

The primary drivers of the decrease in gross profit and gross margin for the Successor period ended June 28, 2026 and Predecessor period ended September 29, 2025 compared to fiscal 2025 included :

• Higher underutilization costs during the Successor period ended June 28, 2026 and the Predecessor period ended September 29, 2025 , related to the achievement of production readiness at our Siler City facility, which expanded our materials capacity, and at our Durham materials facility related to lower factory loadings as we rebalance supply to match weaker end market demand. Prior to the substantial completion of the Siler City facility in late fiscal 2025, these costs were included in start-up costs. We expect to continue to incur significant underutilization costs until market demand for our products meets or exceeds our production capacity.

• $23 million of additional product costs in the Successor period ended June 28, 2026 related to fair value step-ups on work-in-progress and finished goods recorded upon adoption of fresh start accounting, which was fully recognized as the products were sold in the Successor period.

• $42 million of additional amortization expenses related to the recognition of developed technology and changes in the fair value of other intangibles upon the adoption of fresh start accounting, recognized in the Successor period ended June 28, 2026.

• Specific reserves and inventory write-offs related to obsolete products as well as the planned shutdown of our 150mm Durham Fab completed in the Successor period ended June 28, 2026.

• The items above were partially offset by lower restructuring and closure-related charges related to our headcount reduction and facility closure and consolidation plan initiated during the first quarter of fiscal 2025 (the "2025 Restructuring Plan"), a decrease in stock based compensation expense, and lower depreciation expense in the Successor period attributable to the fair value adjustments to property, plant, and equipment as part of our adoption of fresh start accounting. Refer to Note 4, "Fresh Start Accounting" and Note 18, "Restructuring," to our consolidated financial statements in Part II, Item 8 of this Annual Report for additional information.

The $42 million decrease in net revenue for the three months ended September 27, 2026, compared to the three months ended September 28, 2025 was primarily due to:

• Net sales revenue of our Materials Product offerings decreased primarily due to lower volumes and pricing pressures as our substrate customers continue to adjust the timing and size of their orders to rebalance supply to match weaker end market demand. Additionally, we have continued to experience pricing pressure attributable to increased substrate supply, particularly from suppliers in China.

The proportion of Materials Products revenue attributable to long-term supply agreements with customers has decreased compared to the same period in fiscal 2026, resulting in more volatility in the timing and product mix of our materials orders.

Changes to Internal Control Over Financial Reporting

In the course of our ongoing preparations for making management's report on internal control over financial reporting as required by Section 404 of the Sarbanes-Oxley Act of 2002, from time to time we have identified areas in need of improvement and have taken remedial actions to strengthen the affected controls as appropriate. We make these and other changes to enhance the effectiveness of our internal controls over financial reporting, which do not have a material effect on our overall internal control.

Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Our internal control over financial reporting includes those policies and procedures that:

(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

(ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In making the assessment of internal control over financial reporting, our management used the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013 framework). Based on that assessment and those criteria, management has concluded that our internal control over financial reporting was effective as of June 28, 2026.

The effectiveness of our internal control over financial reporting as of June 28, 2026 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report in Part II, Item 8 of this Annual Report.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of for the period covered by this Annual Report. quarter ended September 27, 2026. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this Annual Report, Form 10-Q, our disclosure controls and procedures are effective in that they provide reasonable assurances that the information we are required to disclose in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods required by the SEC's rules and forms and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

We routinely review our internal control over financial reporting and from time to time make changes intended to enhance the effectiveness of our internal control over financial reporting. We will continue to evaluate the effectiveness of our disclosure controls and procedures and internal control over financial reporting on an ongoing basis and will take action as appropriate.

There have been No changes to our internal control over financial reporting as such term is defined were identified in management's evaluation pursuant to Rules 13a-15(f) 13a-15(d) and 15d-15(f) 15d-15(d) under the Exchange Act during the fourth first quarter of fiscal 2026 2027 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Risk factors 193 changes

Described below are various risks and uncertainties that may affect our business. If any of the risks described below actually occurs, our business, financial condition or results of operations could be materially and adversely affected.

Risk categories and certain principal risks under each category include (each described more fully below):

– Risks related to the Chapter 11 Cases

• Historical financial information will not be indicative of our future performance.

• Impact of outstanding debt obligations.

• Influence of certain former holders of the Convertible Notes and Renesas.

• Supply chain disruptions adversely impacting our global supply dependencies.

• Reliance on local utilities and infrastructure at our manufacturing facilities

Risks Related to the Chapter 11 Cases

As a result of the Chapter 11 Cases, our historical financial information will not be indicative of our future performance, and we may not realize all of the intended benefits of the Chapter 11 Cases.

Following our emergence from the Chapter 11 Cases, our capital structure was significantly altered. As a result of the Chapter 11 Cases, our historical financial performance will not be indicative of our future financial performance. In addition, the amounts reported in subsequent consolidated financial statements may materially change relative to our historical consolidated financial statements. We adopted fresh start accounting, and accordingly, our assets and liabilities will be recorded at fair value as of the emergence date, which differs materially from the recorded values of assets and liabilities on our historical consolidated balance sheets. Our financial results after the adoption of fresh start accounting may be different from historical trends.

Furthermore, we may not realize any or all of the intended benefits of the Chapter 11 Cases, the benefits may not be on the terms or in the manner we expect, and the costs incurred may exceed the intended benefits. The occurrence of one or more of these events could have a material and adverse effect on our operations, financial condition and reputation and we cannot assure you that having been subject to bankruptcy proceedings will not adversely affect our operations in the future. Additionally, other risks we face, as described in this Annual Report, may be exacerbated by the impacts of our emergence from bankruptcy.

We have outstanding debt which could materially restrict our business and adversely affect our financial condition, liquidity and results of operations.

The level of our outstanding debt may adversely affect our operating results and financial condition by, among other things:

• increasing our vulnerability to downturns in our business, to competitive pressures and to adverse general economic and industry conditions;

• requiring the dedication of an increased portion of our expected cash flows from operations to service our indebtedness, thereby reducing the amount of expected cash flow available for other purposes, including capital expenditures, or research and development;

• limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and

• placing us at a competitive disadvantage compared to our peers that may have less indebtedness than we have by limiting our ability to borrow additional funds needed to operate and grow our business and limiting our ability to pursue strategic acquisitions or other inorganic growth opportunities.

Our ability to pay interest and repay the principal for or to refinance any outstanding indebtedness under the New 2L Renesas Convertible Notes, New 2L Non-Renesas Convertible Notes, the New 2L Non-Convertible Notes, the New Senior Secured Notes and the 1.5L Convertible Notes (in each case, as defined below) is dependent upon our ability to manage our business operations, generate sufficient cash flows to service such debt and/or raise additional capital, which is subject to economic, financial, competitive and other factors beyond our control. There can be no assurance that we will be able to manage any of these risks successfully.

The indenture governing the New Senior Secured Notes (the "New Senior Secured Notes Indenture") includes a liquidity maintenance financial covenant requiring us to have an aggregate amount of unrestricted cash and cash equivalents maintained in accounts over which the collateral agent for the New Senior Secured Notes has been granted a perfected first lien security interest of at least $350 million as of the last day of any calendar month. In addition, the New Senior Secured Notes Indenture, the indenture governing the New 2L Non-Convertible Notes (the "New 2L Non-Convertible Notes Indenture"), the indenture governing the New 2L Renesas Convertible Notes (the "New 2L Renesas Convertible Notes Indenture"), the indenture governing the New 2L Non-Renesas Convertible Notes (the "New 2L Non-Renesas Convertible Notes Indenture") and the indenture governing the 1.5L Convertible Notes (the "1.5L Convertible Notes Indenture"), in each case, contain certain restrictions that limit our ability to, among other things: incur additional indebtedness, dispose of assets, pay dividends on or redeem or repurchase shares of our common stock, $0.00125 par value per share ("New Common Stock") or other securities, create liens on assets, make investments and acquisitions or engage in mergers or consolidations, and engage in certain transactions with non-subsidiary guarantors and affiliates. The New Senior Secured Notes Indenture, the New 2L Non-Convertible Notes Indenture, the New 2L Renesas Convertible Notes Indenture, the New 2L Non-Renesas Convertible Notes Indenture and the 1.5L Convertible Notes Indenture (collectively, the "Indentures") also require us to make an offer to repurchase (i) the New Senior Secured Notes, or if the New Senior Secured Notes are redeemed in full, the New 2L Non-Convertible Notes or the 2L Convertible Notes, with 100% of the net cash proceeds of certain non-ordinary course asset sales and casualty events, subject to the ability to reinvest the proceeds of certain casualty events (subject to certain limitations), (ii) in the case of the New Senior Secured Notes, with 100% of the proceeds of certain Department of Energy sponsored financings and in specified amounts upon the receipt of certain extraordinary proceeds and (iii) in the case of the New Senior Secured Notes, the New 2L Non-Convertible Notes, the New 2L Renesas Convertible Notes, the New 2L Non-Renesas Convertible Notes, and the 1.5L Convertible Notes, in full upon a change of control. The restrictions imposed by the Indentures could limit our ability to plan for or react to changing business conditions or could otherwise restrict our business activities and plans (including impairing our ability to obtain other financing). Our ability to comply with the covenants and restrictions imposed by the Indentures is subject to various risks and uncertainties beyond our control. Failure to comply with any of the restrictions and covenants in the Indentures or future financing arrangements could result in a default under those arrangements and under other arrangements containing cross-default provisions. A default would permit holders of the New Senior Secured Notes, the New 2L Non-Convertible Notes, the New 2L Renesas Convertible Notes or the New 2L Non-Renesas Convertible Notes or the 1.5L Convertible Notes, as applicable, to accelerate the maturity of the debt under these arrangements and to foreclose upon any collateral securing the debt. Under these circumstances, we might not have sufficient funds or other resources to satisfy all of our obligations, including our obligations under our Indentures.

Additionally, we are exposed to market value fluctuations and inherent interest rate risk related to our investment portfolio. We have historically invested portions of our available cash in fixed interest rate securities such as high-grade corporate debt, commercial paper, municipal bonds, certificates of deposit, government securities and other fixed interest rate investments. The primary objective of our cash investment policy is preservation of principal. However, these investments are generally not Federal Deposit Insurance Corporation insured and may lose value and/or become illiquid regardless of their credit rating. From time to time, we have also made investments in public and private companies that engage in complementary businesses, which investments are subject to fluctuations in market value. Any fluctuations in the value of our investment portfolio could further impact our ability to address outstanding debt obligations and continue operations.

Certain former convertible noteholders and Renesas may significantly influence matters submitted to stockholders.

Certain former holders of our convertible notes and Renesas have acquired significant ownership interests in our common stock pursuant to the Plan. These stockholders may control outcomes of actions requiring stockholder approval, including director elections, without other stockholders' approval. This concentration could: facilitate or hinder negotiated changes of control; allow for the appointment of board majorities, influencing management and strategy; affect corporate governance, business strategies, and capital allocation; impact stock liquidity, trading price, and volatility; create conflicts if major holders' interests diverge from other stockholders; and either attract or deter potential acquirers.

We may issue additional shares of common stock in connection with the exercise of the warrant issued to Renesas, or the conversion of the outstanding New 2L Renesas Convertible Notes, New 2L Non-Renesas Convertible Notes or 1.5L Convertible Notes, which would result in significant dilution to stockholders.

We may issue additional shares of common stock in connection with outstanding securities that are exercisable or convertible into common stock. Any future exercise of the outstanding warrant issued to Renesas to purchase an aggregate of 4,943,555 shares of the Company's common stock or the conversion of the New 2L Renesas Convertible Notes, New 2L Non-Renesas Convertible Notes or 1.5L Convertible Notes may result in significant dilution to existing stockholders.

We are required to reduce tax attributes due to cancellation of indebtedness income.

Generally, any discharge of our debt obligations for an amount less than the debt's adjusted issue price will give rise to cancellation of debt ("COD") income. Under Section 108 of the Internal Revenue Code of 1986, as amended (the "Code"), a taxpayer is required to exclude COD from gross income if the debtor is under the jurisdiction of a court in a case under Chapter 11 of the Bankruptcy Code and the discharge of debt occurs pursuant to that proceeding. As a consequence of such an exclusion, a taxpayer generally must reduce certain of its tax attributes by the amount of COD income that it excluded from gross income. U.S. federal income tax attributes subject to reduction generally include (i) net operating losses ("NOLs") and NOL carryforwards; (ii) general business credit carryovers; (iii) capital loss carryovers; (iv) tax basis in assets; and (v) foreign tax credit carryovers.

As a result of the implementation of the Plan, we realized a substantial amount of COD income for U.S. federal income tax purposes and our tax attributes will be subject to the foregoing attribute reduction rules. The attribute reduction resulted in a reduction to our net operating losses generated during fiscal 2026 and prior years, which may have an adverse effect on our future cash flow.

Impaired stakeholder confidence and weakened relationships following Chapter 11 emergence may adversely affect our business.

Our emergence from the Chapter 11 Cases on the Effective Date may continue to adversely affect our business, operations, and stakeholder relationships. Customer and vendor confidence may remain impaired, potentially causing: reduced orders or order cancellations; unfavorable contract terms or reluctance by third parties to enter new agreements on acceptable terms or at all; competitive disadvantages as customers shift business to competitors perceived as more stable; and ongoing reputational harm in our markets.

Additionally, investors and capital markets may require demonstrated operational and financial recovery before fully restoring confidence, potentially limiting our access to capital on favorable terms or affecting the trading price of our common stock until sustained performance improvements are evidenced.

Risks Related to Our Markets and Product Demand

Our dependence on a concentrated customer base creates revenue vulnerability.

We receive significant revenue from a limited number of customers and distributors, with two individually representing more than 10% of consolidated revenue for each of the periods from June 30, 2025 to September 29, 2025 and September 30, 2025 to June 28, 2026. Many customer orders are made on a purchase order basis without long-term commitments. Therefore, these customers may alter their purchasing behavior with little or no notice to us for various reasons, including developing, or, in the case of our distributors, their customers developing, their own product solutions; choosing to purchase or distribute product from our competitors; incorrectly forecasting end market demand for their products; altering their purchasing practices as a result of our emergence from the Chapter 11 Cases and the implementation of the Plan; or experiencing a reduction in their market share in the markets for which they purchase our products. If our customers alter their purchasing behavior, if our customers' purchasing behavior does not match our expectations, or if we encounter any problems collecting amounts due from them, our business, financial condition, and results of operations could be negatively impacted.

Furthermore, we continue to expand into new markets and new market segments. Many of our existing customers who purchase our silicon carbide substrate materials develop and manufacture devices, die and components using those wafers that are offered in the same power market. As a result, some of our current customers perceive us as a competitor in these market segments. In response, our customers may reduce or discontinue their orders for our substrate materials. This reduction in or discontinuation of orders could occur faster than our sales growth in these new markets, which could adversely affect our business, financial condition, and results of operations.

Competition from established semiconductor companies and state-supported international players threatens our market position .

The markets for our products are highly competitive. In the semiconductor market, we compete with companies that have greater market share, name recognition, distribution, government subsidies and sales channels, and/or technical resources than we do, as well as state-supported international players who may have access to significant resources. Competitors continue to offer new products with aggressive pricing, additional features and improved performance. Aggressive pricing actions by our competitors in our businesses could reduce margins if we are not able to reduce costs at an equal or greater rate than the sales price decline. Competitors may form strategic alliances with key customers, leading to further pricing pressure and reduced market share. Our inability to recover substantial development, engineering, and manufacturing costs—particularly significant given our current underutilization costs at the Mohawk Valley and Siler City facilities, softening demand and continued price pressure in certain applications could compound these challenges.

As competition increases, we need to continue to develop new products that meet or exceed the needs of our customers. Therefore, our ability to continually produce more efficient and lower cost power and materials products that meet the evolving needs of our customers will be critical to our success. Competitors may also try to align with some of our strategic customers. This could lead to lower prices for our products, reduced demand for our products and a corresponding reduction in our ability to recover development, engineering and manufacturing costs. Any of these developments could adversely affect our business, financial condition, and results of operations.

Our growth depends on the adoption of our products, which is impacted by trends in the global silicon carbide market and customer behavior in response to those trends.

Our growth depends significantly on adoption of our products within served markets and our ability to influence adoption rates. The semiconductor industry is characterized by rapid technological change, high capital expenditures, short product life cycles, and continuous process technology advancements. Markets we serve are in different adoption stages and characterized by constant change, rapid obsolescence, price erosion, evolving standards, and supply-demand fluctuations. As markets mature, additional fluctuations may result from customer base variability and consolidations, characterized by lower product demand, production overcapacity, higher inventory levels, aggressive competitor pricing, longer lead times for key components, supply delays, and production disruptions. We have experienced and may continue experiencing these conditions, which could adversely affect our business, financial condition, and results of operations.

Our ability to develop and introduce new products that are adopted by customers, in new and established markets, will impact our ability to successfully grow our business.

Our future success depends on our ability to deliver new, higher-performing and/or lower-cost solutions for existing and new markets and customer acceptance of those solutions. We have experienced delays in completing development, introduction, and qualification of new products. Our research and development efforts address increasingly complex problems, and not all projects will succeed. The semiconductor industry is characterized by rapid technological change, and our ability to compete effectively depends on our continued innovation in silicon carbide technology and our capacity to anticipate and respond to evolving customer requirements across automotive, industrial, energy, and AI data center applications. AI-related demand for our products is an emerging and rapidly evolving market opportunity, and the expected timing and magnitude of such demand may change significantly.

Successful development, introduction, and acceptance of our products depend on multiple critical factors. These include qualification and acceptance of new product and system designs, especially for automotive applications requiring stringent reliability and safety standards. We must also rely on our customers' ability to develop competitive products incorporating our solutions, as well as market acceptance of both our products and our customers' end products. The effective transfer of complex products from development to manufacturing presents significant challenges, which requires substantial capital investment and process refinement. Additional factors necessary for successful development include timely and cost-effective product introduction, achieving technology breakthroughs necessary for commercially viable products, and converting design-ins (customer commitments to purchase our products) to significant volume sales over multi-year qualification cycles.

Our ability to succeed also requires accurate prediction of market requirements, the capability to predict, influence, and react to evolving industry standards, and acceptance of new technology in certain markets where silicon carbide solutions compete with established silicon-based alternatives. We must maintain robust intellectual property protection, ensure availability of qualified research and development personnel in a competitive labor market, complete designs and development activities on schedule, and develop repeatable processes for manufacturing new products in sufficient quantities with desired specifications at competitive costs. If any of these factors become problematic, we may not deliver and introduce new products in a timely or cost-effective manner. Our continued focus on accelerating the transition to 200mm substrate production is critical to achieving manufacturing scale and cost competitiveness. Any inability to balance production capacity with customer demands or continue this transition in a timely and cost-effective manner would negatively impact our competitive position, business, financial condition, and results of operations.

Cyclical market patterns and potential downturns in our end markets could impact demand, which could cause volatility in our revenue and profitability.

Industries we serve experience significant supply-demand and pricing fluctuations affecting our revenue and profitability. The semiconductor industry's rapid technological change, high capital expenditures, short product life cycles, and continuous advancements create volatility. Market maturity brings variability from customer base changes and consolidations, characterized by low demand, overcapacity, higher inventories, and aggressive pricing. We have experienced and may continue experiencing these conditions, which could adversely impact our business, financial condition, and results of operations.

Distributors may not expand their customer base or effectively anticipate demand.

We sell a portion of our products through distributors, including one that represented over 10% of revenue during each of the periods from June 30, 2025 to September 29, 2025 and September 30, 2025 to June 28, 2026. We depend on distributors to expand their customer base and anticipate demand. Their success directly impacts our growth and profitability. Distributors must balance adequate inventory against obsolescence risk—particularly relevant for technology products—based on market cycles and internal factors largely outside our control. Both we and our distributors may be required to shift business relationships based on product availability, performance, and strategic priorities.
