**MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.**

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**(Unaudited)**

**1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

**Unaudited Interim Financial Information**—The accompanying unaudited, condensed consolidated financial statements have been prepared according to the rules and regulations of the United States (the "U.S.") Securities and Exchange Commission (the "SEC") and, in the opinion of management, reflect all adjustments, which include normal recurring adjustments, necessary for a fair statement of the condensed consolidated balance sheets, condensed consolidated statements of operations, comprehensive income (loss), stockholders' equity and cash flows of MACOM Technology Solutions Holdings, Inc. ("MACOM," the "Company," "us," "we" or "our") for the periods presented. We prepare our interim financial information using the same accounting principles we use for our annual audited consolidated financial statements. Certain information and note disclosures normally included in the annual audited consolidated financial statements have been condensed or omitted in accordance with prescribed SEC rules. We believe that the disclosures made in our condensed consolidated financial statements and the accompanying notes are adequate to make the information presented not misleading.

The condensed consolidated balance sheet as of October 3, 2025 is as reported in our audited consolidated financial statements as of that date. Our accounting policies are described in the notes to our October 3, 2025 consolidated financial statements, which were included in our Annual Report on Form 10-K for our fiscal year ended October 3, 2025 filed with the SEC on November 14, 2025 (the "2025 Annual Report on Form 10-K"). We recommend that the financial statements included in this Quarterly Report on Form 10-Q be read in conjunction with the consolidated financial statements and notes included in our 2025 Annual Report on Form 10-K.

**Principles of Consolidation and Basis of Presentation**—The accompanying condensed consolidated financial statements include our accounts and the accounts of our majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. In the condensed consolidated financial statements, certain prior year amounts within the condensed consolidated statement of cash flows have been reclassified to conform to the current year presentation.

We have a 52- or 53-week fiscal year ending on the Friday closest to the last day of September. Fiscal year 2026 includes 52 weeks and fiscal year 2025 included 53 weeks. To offset the effect of holidays, for fiscal years in which there are 53 weeks, we include the extra week arising in such fiscal years in the first fiscal quarter. Our first fiscal quarter ended January 2, 2026 included 13 weeks and the first fiscal quarter ended January 3, 2025 included 14 weeks.

**Use of Estimates**—The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities during the reporting periods, the reported amounts of revenue and expenses during the reporting periods and the disclosure of contingent assets and liabilities at the date of the financial statements. On an ongoing basis, we base estimates and assumptions on historical experience, currently available information and various other factors that management believes to be reasonable under the circumstances. Actual results may differ materially from these estimates and assumptions. The accounting policies which our management believes involve the most significant application of judgment or involve complex estimation, are inventories and associated reserves; revenue reserves; business combinations; goodwill and intangible asset valuation; share-based compensation valuations and income taxes.

**Property and Equipment**—Property and equipment is stated at cost, less accumulated depreciation and amortization. Expenditures for maintenance and repairs are charged to expense as incurred, whereas major improvements that significantly extend the useful life of the assets are capitalized as additions to property and equipment.

As of September 28, 2024, the Company changed its accounting estimate for the expected useful lives of certain fabrication-related machinery and equipment. The Company evaluated its current asset base and reassessed the estimated useful lives of certain machinery and equipment in connection with its recent usage of older equipment, including considering the technological and physical obsolescence of such machinery and equipment. Based on our ability to re-use equipment across generations of process technologies and historical usage trends, the Company determined that the expected useful lives for certain fabrication-related machinery and equipment should be increased to ten years to reflect more closely the estimated economic lives of those assets. This change in estimate was applied prospectively effective for the first quarter of fiscal year 2025 and resulted in a decrease in depreciation expense of $0.7 million for the three months ended January 3, 2025, to cost of revenue. This benefit increased income from operations by $0.7 million and earnings per share by $0.01, for the three months ended January 3, 2025.

**Recent Accounting Pronouncements**—Our Recent Accounting Pronouncements are described in our 2025 Annual Report on Form 10-K.

------

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, *Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures*, which improves disclosures about a public entity's reportable segments and addresses requests from investors and other allocators of capital for additional, more detailed information about a reportable segment's expenses. The amendments in this update improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful financial analyses. We adopted this ASU for the fiscal year ended October 3, 2025. This ASU was applied on a retrospective basis. See *Note 17 - Segment Reporting and Geographic Information* for additional information on our interim disclosures.

In November 2024, the FASB issued ASU 2024-04, *Debt - Debt with Conversion and Other Options (Subtopic 470-20) Induced Conversions of Convertible Debt Instruments*, which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. We elected to early adopt ASU 2024-04 in the first quarter of fiscal year 2025 and applied the amendment when assessing the accounting treatment for our debt extinguishment (discussed in *Note 10 - Debt*).

**Pronouncements for Adoption in Subsequent Periods**

In December 2023, the FASB issued ASU 2023-09, *Income Taxes (Topic 740) Improvements to Income Tax Disclosures*, which requires greater disaggregation of income tax disclosures. The amendments in this update improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. Other amendments in this update improve the effectiveness and comparability of disclosures by (1) adding disclosures of pretax income (or loss) and income tax expense (or benefit) and (2) removing disclosures that no longer are considered cost beneficial or relevant. This ASU should be applied on a prospective basis, with retrospective application permitted. The guidance in this update is effective for annual reporting periods beginning after December 15, 2024. We are currently evaluating the future effect the adoption of this ASU will have on our consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, *Income Statement Reporting Comprehensive Income - Expense Disaggregation Disclosures*, as amended by ASU 2025-01, *Income Statement Reporting Comprehensive Income - Expense Disaggregation Disclosures: Clarifying the Effective Date,* which requires disclosure, in the notes to financial statements, of specified information about certain costs and expenses. The amendments in this update improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. This ASU should be applied on a prospective basis, with retrospective application permitted. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the future effect the adoption of this ASU will have on our consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU 2025-06, "*Intangible - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software."* The ASU requires entities to begin capitalizing software costs when management authorizes and commits to funding the software project, and it is probable that the project will be completed and the software will be used for its intended purpose. The amendments in this ASU are effective for fiscal years beginning after December 15, 2027. Early adoption is permitted. We are currently evaluating the future effect the adoption of this ASU will have on our consolidated financial statements and related disclosures.

**2. REVENUE**

**Disaggregation of Revenue** 

We disaggregate revenue from contracts with customers by markets and geography, as we believe it best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.

------

The following tables present our revenue disaggregated by markets and geography (in thousands):

---

| | | |
|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** |
| | **January 2, 2026** | **January 3, 2025** |
| **Revenue by Market:** | | |
| &nbsp;&nbsp;&nbsp;Industrial & Defense | $117713 | $97400 |
| &nbsp;&nbsp;&nbsp;Data Center | 85754 | 65284 |
| &nbsp;&nbsp;&nbsp;Telecom | 68145 | 55438 |
| Total | $271612 | $218122 |

---

---

| | | |
|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** |
| | **January 2, 2026** | **January 3, 2025** |
| **Revenue by Geographic Region**<sup>(1)</sup>**:** | | |
| &nbsp;&nbsp;&nbsp;United States | $123836 | $97272 |
| &nbsp;&nbsp;&nbsp;China | 85223 | 62728 |
| &nbsp;&nbsp;&nbsp;Asia Pacific, excluding China | 30552 | 20538 |
| &nbsp;&nbsp;&nbsp;Other Countries <sup>(2)</sup> | 32001 | 37584 |
| Total | $271612 | $218122 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1)Revenue by geographic region is aggregated by customer billing address.

&nbsp;&nbsp;&nbsp;&nbsp;(2)No country or region represented greater than 10% of our total revenue as of the dates presented, other than the United States, China and Asia Pacific region as presented above.

**Contract Balances** 

We record contract assets or contract liabilities depending on the timing of revenue recognition, billings and cash collections on a contract-by-contract basis. Our contract liabilities primarily relate to deferred revenue, including advanced consideration received from customers for contracts prior to the transfer of control to the customer, and, therefore, revenue is subsequently recognized upon delivery of products and services.

The following table presents the changes in contract liabilities during the three months ended January 2, 2026 (in thousands, except percentage):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **January 2, 2026** | **October 3, 2025** | **$ Change** | **% Change** |
| Contract liabilities | $6534 | $7676 | $(1142) | (14.9)% |

---

During the three months ended January 2, 2026 and January 3, 2025, we recognized sales of $3.3 million and $0.9 million, respectively, that were included in the contract liabilities balance as of the beginning of the period. The decrease in contract liabilities during the three months ended January 2, 2026 was primarily related to recognition of revenue that was previously deferred for products and services invoiced prior to when certain of our customers obtained control of such products and/or services, partially offset by deferral of revenue for additional invoicing prior to when our customers obtain control of such products and/or services.

------

**3. ACQUISITIONS**

**ENGIN-IC, Inc.—**On November 5, 2024, we completed the acquisition of ENGIN-IC, Inc. ("ENGIN-IC"), a fabless semiconductor company that designs advanced gallium arsenide ("GaAs") and gallium nitride ("GaN") monolithic microwave integrated circuits ("MMICs") and integrated microwave assemblies located in Plano, Texas and San Diego, California (the "ENGIN-IC Acquisition"). We acquired ENGIN-IC to further expand and strengthen our MMIC and module design capabilities. In connection with the ENGIN-IC Acquisition, we acquired all of the outstanding shares of ENGIN-IC for a total purchase price of approximately $14.4 million with cash consideration of $12.7 million, net of cash acquired of $0.2 million, and deferred consideration payable of $1.5 million related to customary agreement provisions not associated with future performance of the acquired business. We paid $0.7 million of the deferred consideration during the three months ended January 2, 2026 and the remainder is expected to be paid during our third fiscal quarter of 2026. The ENGIN-IC Acquisition was accounted for as a business combination and the operations of ENGIN-IC have been included in our consolidated financial statements since the date of acquisition. We finalized the ENGIN-IC Acquisition purchase accounting during the fiscal quarter ended January 2, 2026 and adjustments were immaterial. We recorded the final allocation of the purchase price for ENGIN-IC, which primarily resulted in intangible assets, including acquired technology and customer relationships, of $9.7 million and goodwill of $5.1 million.

Consolidated estimated pro forma unaudited revenue and consolidated estimated pro forma net loss during the three months ended January 3, 2025 and the actual results of operations for ENGIN-IC since the acquisition date are not material to our condensed consolidated financial statements.

**4. INVESTMENTS**

All investments are short-term in nature and are invested in corporate bonds, commercial paper, U.S. Treasuries and agency bonds, and are classified as available-for-sale. The Company classifies investments with maturity dates greater than twelve months in short-term investments rather than long-term investments based on the nature of the securities and the availability for use in current operations. The Company believes this method is preferable because it is more reflective of the Company's assessment of its overall liquidity position. These investments are owned directly by the Company and are segregated in brokerage custody accounts. The amortized cost, gross unrealized holding gains or losses and fair value of our available-for-sale investments by major investment type are summarized in the tables below (in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **January 2, 2026** | **January 2, 2026** | **January 2, 2026** | **January 2, 2026** |
| | **Amortized<br>Cost** | **Gross<br>Unrealized<br>Holding Gains** | **Gross<br>Unrealized<br>Holding Losses** | **Aggregate Fair<br>Value** |
| Corporate bonds | $555434 | $3143 | $(95) | $558482 |
| Commercial paper | 29900 | 5 |  | 29905 |
| U.S. Treasuries and agency bonds | 60353 | 139 | (31) | 60461 |
| Total short-term investments | $645687 | $3287 | $(126) | $648848 |

---

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **October 3, 2025** | **October 3, 2025** | **October 3, 2025** | **October 3, 2025** |
| | **Amortized<br>Cost** | **Gross<br>Unrealized<br>Holding Gains** | **Gross<br>Unrealized<br>Holding Losses** | **Aggregate Fair<br>Value** |
| Corporate bonds | $554433 | $3222 | $(76) | $557579 |
| Commercial paper | 49510 | 6 |  | 49516 |
| U.S. Treasuries and agency bonds | 66594 | 155 | (11) | 66738 |
| Total short-term investments | $670537 | $3383 | $(87) | $673833 |

---

&nbsp;&nbsp;&nbsp;&nbsp;

The contractual maturities of available-for-sale investments were as follows (in thousands):

---

| | | |
|:---|:---|:---|
| | **January 2,<br>2026** | **October 3, 2025** |
| Less than one year | $182227 | $211245 |
| Over one year | 466621 | 462588 |
| Total available-for-sale investments | $648848 | $673833 |

---

We have determined that the gross unrealized losses on available for sale securities as of January 2, 2026 and October 3, 2025 are temporary in nature and/or do not relate to credit loss, and therefore, there is no expense for credit losses recorded in

------

our condensed consolidated statements of operations. Unrealized gains and losses on available-for-sale investments are reported as a separate component of stockholders' equity within accumulated other comprehensive income.

**5. FAIR VALUE AND FINANCIAL INSTRUMENTS**

We group our financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine fair value. These levels are:

---

| |
|:---|
| ***Level 1*** *- Quoted prices in active markets for identical assets or liabilities.*  |
| ***Level 2*** *- Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data.* |
| ***Level 3*** *- Fair value is derived from valuation techniques in which one or more significant inputs are unobservable, including assumptions and judgments made by us.* |

---

**Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis** 

We measure certain assets and liabilities at fair value on a recurring basis such as our financial instruments. There have been no transfers between Level 1, 2 or 3 assets or liabilities during the three months ended January 2, 2026.

Assets and liabilities measured at fair value on a recurring basis consist of the following (in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **January 2, 2026** | **January 2, 2026** | **January 2, 2026** | **January 2, 2026** |
| | **Fair Value** | **Active Markets for Identical Assets (Level 1)** | **Observable Inputs (Level 2)** | **Unobservable Inputs (Level 3)** |
| **Assets** | | | | |
| &nbsp;&nbsp;&nbsp;Money market funds | $56398 | $56398 | $— | $— |
| &nbsp;&nbsp;&nbsp;U.S. Treasuries and agency bonds | 60461 | 35490 | 24971 |  |
| &nbsp;&nbsp;&nbsp;Corporate bonds | 558482 |  | 558482 |  |
| &nbsp;&nbsp;&nbsp;Commercial paper | 29905 |  | 29905 |  |

| &nbsp;&nbsp;&nbsp;Commercial paper | 49516 |  | 49516 |  |
| Total assets measured at fair value | $737644 | $109184 | $628460 | $— |

---

**Derivatives**

We have foreign currency exposure arising from certain of our Euro and Yen denominated intercompany debt. We have entered into foreign currency exchange hedging contracts associated with this intercompany debt to partially mitigate the impact of currency rate changes. They are not designated as cash flow or fair value hedges under Accounting Standards Codification ("ASC") 815, *Derivatives and Hedging*. Changes in fair value are reported in current period earnings. These gains and losses are intended to offset the gains and losses recorded on the associated intercompany debt. We do not use derivative financial instruments for trading or speculation purposes.

As of January 2, 2026 and October 3, 2025, we had $47.0 million and $36.0 million, respectively, in notional forward foreign currency contracts. As of January 2, 2026 and October 3, 2025, the fair value of derivative instruments not designated as hedges was immaterial.

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Property and equipment, net | $234705 | $230291 |

---

In August 2022, the U.S. government enacted the CHIPS and Science Act of 2022 ("CHIPS Act"), which provides funding for manufacturing grants and research investments and established a 25% investment tax credit ("ITC") for certain qualifying investments in U.S. semiconductor manufacturing equipment. On July 4, 2025 the U.S. Congress passed a federal statute controlling tax and spending policies (the "July 4, 2025 Bill"). As part of the July 4, 2025 Bill, this ITC was increased to 35% for assets placed into service after December 31, 2025. We account for the investment tax credit as a reduction to the carrying value of the qualifying asset and record a corresponding receivable for expected tax credits in connection with the CHIPS Act. As of January 2, 2026 and October 3, 2025, there was a $6.3 million and $5.6 million reduction, respectively, to the gross carrying amounts of the qualifying assets in the condensed consolidated balance sheet.

Depreciation and amortization expense related to property and equipment for the three months ended January 2, 2026 and January 3, 2025 was $9.2 million and $7.3 million, respectively. Accumulated amortization on finance lease assets as of January 2, 2026 and October 3, 2025 was $10.7 million and $10.3 million, respectively.

**8. INTANGIBLE ASSETS**

Amortization expense related to intangible assets is as follows (in thousands):

***2026 Convertible Notes***

On March 25, 2021, we issued 0.25% convertible senior notes due in fiscal year 2026, pursuant to an indenture dated as of such date (the "2021 Indenture"), between the Company and U.S. Bank National Association, as trustee, with an aggregate principal amount of $400.0 million (the "Initial Notes"), and on April 6, 2021, we issued an additional $50.0 million aggregate principal amount (the "Additional Notes") (together, the "2026 Convertible Notes"). The Additional Notes were issued and sold to the initial purchaser of the Initial Notes, pursuant to the option to purchase the Additional Notes granted by the Company to the initial purchaser and have the same terms as the Initial Notes.

On December 12, 2024, we entered into separate, privately negotiated exchange and subscription agreements (the "Exchange and Subscription Agreements") with a limited number of holders of the 2026 Convertible Notes. Under the terms of the Exchange and Subscription Agreements, the holders exchanged $288.8 million in aggregate principal amount of 2026 Convertible Notes held by them for $257.7 million of our 2029 Convertible Notes (defined below), 1,582,958 newly-issued shares of the Company's common stock, par value $0.001 per share, issued at a fair value of $205.9 million, and $17.6 million in cash. These exchanges resulted in aggregate pre-tax debt extinguishment charges of $193.1 million. The Company also issued approximately $86.6 million in additional aggregate principal amount of the 2029 Convertible Notes in a private placement to certain investors (the "Subscription" and, together with the Exchange, the "Transactions"). The Transactions closed on December 19, 2024.

Following the closing of the Transactions, the aggregate principal balance of the 2026 Convertible Notes is $161.2 million and the terms of the 2021 Indenture are unchanged. The 2026 Convertible Notes will mature on March 15, 2026 unless earlier converted, redeemed or repurchased.

Holders of the 2026 Convertible Notes may convert their notes at their option at any time prior to the close of business on the business day immediately preceding December 15, 2025 in multiples of $1,000 principal amount, only under the following circumstances: (i) during any fiscal quarter commencing after the fiscal quarter ending on July 2, 2021 (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price for the notes on each applicable trading day; (ii) during the five business day period after any five consecutive trading day period (the "Measurement Period") in which the "trading price" (as defined in the 2021 Indenture) per $1,000 principal amount of the notes for each trading day of the Measurement Period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the notes on each such trading day; (iii) if we call such notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the applicable redemption date; or (iv) upon the occurrence of specified corporate events described in the 2021 Indenture. On or after December 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes in multiples of $1,000 principal amount, regardless of the foregoing circumstances.

The initial conversion rate for the 2026 Convertible Notes is 12.1767 shares of common stock per $1,000 principal amount of the notes, equivalent to an initial conversion price of approximately $82.12 per share of common stock. The conversion rate will be subject to adjustment upon the occurrence of certain specified events in the 2021 Indenture.

In November 2021, we made an irrevocable election to pay cash for the aggregate principal amount of notes to be converted. Upon conversion of the 2026 Convertible Notes, we are required to pay cash up to the aggregate principal amount of the notes to be converted and pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, in respect of the remainder, if any, of our conversion obligation in excess of the

------

aggregate principal amount of the notes being converted (subject to, and in accordance with, the settlement provisions of the 2021 Indenture). Effective December 15, 2025, we elected to settle our conversion obligation in excess of principal in shares of our common stock, for all conversions occurring on or after that date.

We may redeem for cash all or any portion of the notes, at our option, on or after March 20, 2024 and prior to December 15, 2025, if the last reported sale price per share of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which we provide notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, to, but not including, the redemption date.

The 2021 Indenture does not contain any financial or operating covenants or restrictions on the payments of dividends, the making of investments, the incurrence of indebtedness or the purchase or prepayment of securities by us or any of our subsidiaries.

For the three months ended January 2, 2026, total interest expense for the 2026 Convertible Notes was $0.2 million of which $0.1 million was for coupon interest. For the three months ended January 3, 2025, total interest expense was $0.6 million of which $0.3 million was for coupon interest.

The fair value of our 2026 Convertible Notes was $334.2 million and $251.6 million as of January 2, 2026 and October 3, 2025, respectively, and was determined based on quoted prices in markets that are not active, which is considered a Level 2 valuation input.

In September 2025, certain holders exercised their right to convert $0.5 million of the notes. The transaction settled during the three months ended January 2, 2026 and we paid $0.5 million principal in cash and issued 2,610 shares of our common stock for the conversion premium.

The full principal amount of the 2026 Convertible Notes of $160.7 million is due on March 15, 2026. The 2026 Convertible Notes balance of $160.6 million, net of deferred financing costs, is classified as short-term debt in our condensed consolidated balance sheet.

***2029 Convertible Notes***

On December 19, 2024, we issued 0.00% convertible senior notes due in fiscal year 2030, pursuant to an indenture dated as of such date (the "2024 Indenture"), between the Company and U.S. Bank National Association, as trustee with an aggregate principal amount of $344.3 million (the "2029 Convertible Notes").

Holders of the 2029 Convertible Notes may convert their notes at their option at any time prior to the close of business on the business day immediately preceding September 15, 2029 in multiples of $1,000 principal amount, only under the following circumstances: (i) during any fiscal quarter commencing after the fiscal quarter ending on April 4, 2025 (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the notes on each applicable trading day; (ii) during the five business day period after any five consecutive trading day period (the "Measurement Period") in which the "trading price" (as defined in the 2024 Indenture) per $1,000 principal amount of the notes for each trading day of the Measurement Period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the notes on each such trading day; (iii) if we call such notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (iv) upon the occurrence of specified corporate events described in the 2024 Indenture. On or after September 15, 2029 until the close of business on the second scheduled trading day immediately preceding the maturity date, the holders may convert their notes, in multiples of $1,000 principal amount, regardless of the foregoing circumstances.

The initial conversion rate for the Notes is 5.7463 shares of common stock (subject to adjustment as provided for in the 2024 Indenture) per $1,000 principal amount of the notes, which is equal to an initial conversion price of approximately $174.03 per share of common stock.

------

The 2029 Convertible Notes do not bear regular interest, and the principal amount of the notes does not accrete. The notes are senior unsecured obligations of the Company and will mature on December 15, 2029, unless earlier redeemed, repurchased or converted. Upon conversion of the 2029 Convertible Notes, we are required to pay cash up to the aggregate principal amount of the notes to be converted and pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, in respect of the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of the notes being converted (subject to, and in accordance with, the settlement provisions of the 2024 Indenture). We must notify the holders of the 2029 Convertible Notes of our settlement method for our conversion obligation in excess of the aggregate principal amount no later than September 15, 2029, for conversions occurring on or after that date. We may redeem for cash all or any portion of the notes, at our option, on or after December 20, 2027 and prior to September 15, 2029 if the last reported sale price per share of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which we provide notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, to, but not including, the redemption date.

The 2024 Indenture does not contain any financial or operating covenants or restrictions on the payments of dividends, the making of investments, the incurrence of indebtedness or the purchase or prepayment of securities by us or any of our subsidiaries.

For the three months ended January 2, 2026 and January 3, 2025, total interest expense for the 2029 convertible notes was $0.3 million and less than $0.1 million, respectively, which represents amortization of issuance costs.

The fair value of our 2029 Convertible Notes was $424.5 million and $353.3 million as of January 2, 2026 and October 3, 2025, respectively. The fair value was determined based on quoted prices in markets that are not active, which is considered a Level 2 valuation input.

The full principal amount of the 2029 Convertible Notes of $344.3 million is due on December 15, 2029.

**11. FINANCING OBLIGATIONS**

We are party to a power purchase agreement for the use of electric power and thermal energy producing systems at our fabrication facility in Lowell, Massachusetts. We do not own these systems; however, we control the use of the assets during operation. As of January 2, 2026 and October 3, 2025, the net book value of the systems in Property and equipment, net was $7.4 million and $7.5 million, respectively, and the corresponding liability was $8.9 million and $9.0 million, respectively, primarily classified in Financing obligation on our condensed consolidated balance sheet.

*Sale-Leaseback*

Our lease for the wafer fabrication facility in Research Triangle Park ("RTP"), North Carolina (the "RTP Fab") is considered a failed sale-leaseback for accounting purposes. Accordingly, we recognize this transaction as a financing arrangement. As of January 2, 2026 and October 3, 2025, the net book value of the land and building in Property and equipment, net was $28.5 million and $28.6 million, respectively, and the corresponding liability was $28.5 million and $28.5 million, respectively, primarily classified in Financing obligation on our condensed consolidated balance sheet.

**13. COMMITMENTS AND CONTINGENCIES**

From time to time, we may be subject to commercial disputes, employment issues, claims by other companies in the industry that we have infringed their intellectual property rights and other similar claims and litigation. Any such claims may lead to future litigation and material damages and defense costs. We were not involved in any material pending legal proceedings during the three months ended January 2, 2026.

------

**14. STOCKHOLDERS' EQUITY AND SHARE-BASED COMPENSATION**

We have authorized 10 million shares of $0.001 par value preferred stock and 300 million shares of $0.001 par value common stock as of January 2, 2026.

**Stock Plans**

As of January 2, 2026, we had approximately 2.5 million shares available for issuance under our 2021 Omnibus Incentive Plan (the "2021 Plan") and approximately 1.0 million shares available for issuance under our 2021 Employee Stock Purchase Plan (the "Employee Stock Purchase Plan"). Under the 2021 Plan, we have the ability to issue incentive stock options ("ISOs"), non-statutory stock options ("NSOs"), stock appreciation rights ("SARs"), restricted stock awards ("RSAs"), unrestricted stock awards, stock units (including restricted stock units ("RSUs") and performance-based restricted stock units ("PRSUs"), performance awards, cash awards, and other share-based awards to employees, directors, consultants and advisors. The ISOs and NSOs must be granted at an exercise price, and the SARs must be granted at a base value, per share of not less than 100% of the closing price of a share of our common stock on the date of grant (or, if no closing price is reported on that date, the closing price on the immediately preceding date on which a closing price was reported) (110% in the case of certain ISOs). Certain of the share-based awards granted and outstanding as of January 2, 2026 are subject to accelerated vesting upon a change in control of the Company.

**Incentive Stock Units**

Aside from the equity plans described above, we also grant incentive stock units ("ISUs") to certain of our international employees which typically vest over three or four years and for which the fair value is determined by our underlying stock price, which are classified as liabilities and settled in cash upon vesting.

As of January 2, 2026 and October 3, 2025, the fair value of outstanding ISUs was $5.7 million and $5.1 million, respectively, and the associated accrued compensation liability was $2.3 million and $3.7 million, respectively. During the three months ended January 2, 2026 and January 3, 2025, we recorded an expense for ISU awards of $1.6 million and $1.5 million, respectively. These expenses are not included in the share-based compensation expense totals below.

**Share-Based Compensation**

The following table shows a summary of share-based compensation expense included in the condensed consolidated statements of operations (in thousands):

---

| | | |
|:---|:---|:---|
|  | **Three Months Ended** | **Three Months Ended** |
|  | **January 2,<br>2026** | **January 3,<br>2025** |
| Cost of revenue | $2244 | $2945 |
| Research and development | 8774 | 11251 |
| Selling, general and administrative | 11120 | 11324 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total share-based compensation expense | $22138 | $25520 |

---

As of January 2, 2026, the total unrecognized compensation costs related to RSUs and PRSUs was $153.5 million, which we expect to recognize over a weighted-average period of 2.2 years. As of January 2, 2026, total unrecognized compensation cost related to our Employee Stock Purchase Plan was $1.6 million.

**Restricted Stock Units and Performance-Based Restricted Stock Units**

A summary of RSU and PRSU activity for the three months ended January 2, 2026 is as follows:

---

| | | |
|:---|:---|:---|
| | **Number of shares<br>(in thousands)** | **Weighted-<br>Average<br>Grant Date Fair Value** |
| Balance as of October 3, 2025 | 1419 | $97.19 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Granted | 499 | $160.86 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Performance-based adjustment <sup>(1)</sup>  | 201 | $85.93 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Vested and released | (787) | $83.06 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Forfeited, canceled or expired | (25) | $91.33 |
| Balance as of January 2, 2026 | 1307 | $128.37 |

---

------

&nbsp;&nbsp;&nbsp;&nbsp;(1) The amount shown represents performance adjustments for performance-based awards. These were granted in prior fiscal years and vested during the three months ended January 2, 2026 based on the Company's achievement of adjusted earnings per share and total shareholder return performance conditions.

Stock awards that vested during the three months ended January 2, 2026 and January 3, 2025 had combined fair values of $126.8 million and $106.7 million, respectively, as of the vesting date. RSUs granted generally vest over a period of three or four years.

*Market-based PRSUs*

We granted 103,247 market-based PRSUs during the three months ended January 2, 2026, at a weighted average grant date fair value of $208.84 per share. Recipients may earn between 0% and 200% of the target number of shares based on the Company's achievement of total stockholder return in comparison to a peer group of companies in the PHLX Semiconductor Sector Index (^SOX) over a period of approximately three years. The fair value of the awards was estimated using a Monte Carlo simulation and compensation expense is recognized ratably over the service period based on the grant date fair value of the awards subject to the market condition. The expected volatility of the Company's common stock was estimated based on the historical average volatility rate over the three-year period. The dividend yield assumption was based on historical and anticipated dividend payouts. The risk-free rate assumption was based on observed interest rates consistent with the three-year measurement period.

The weighted-average assumptions used to value the market-based PRSU awards are as follows:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** |
| | **January 2,<br>2026** | **January 2,<br>2026** |
| Weighted-average grant date stock price | $| 148.31 |
| Weighted-average stock price at the start of the performance period | $| 128.76 |
| Weighted-average risk free interest rate | 3.5% | 3.5% |
| Weighted-average years to maturity | 2.9 | 2.9 |
| Weighted-average expected volatility rate | 41.6% | 41.6% |
| Weighted-average expected dividend yield |  |  |

**15. INCOME TAXES**

We are subject to income tax in the U.S. as well as other tax jurisdictions in which we conduct business. Earnings from non-U.S. activities are subject to local country income tax and may also be subject to U.S. income tax. For interim periods, we record a tax provision or benefit based upon the estimated effective tax rate expected for the full fiscal year, adjusted for material discrete taxation matters arising during the interim periods. Our quarterly tax provision or benefit, and our quarterly estimate of the annual effective tax rate, are subject to significant variation due to several factors. These factors include items such as variability in accurately predicting pre-tax income/loss, the mix of income in jurisdictions in which we operate, intercompany transactions, changes in how we do business, tax law developments, including, but not limited to, impacts associated with the July 4, 2025 Bill, the realizability of our deferred tax assets, any related valuation allowance and relative changes in permanent tax benefits or expenses.

The provision for income taxes and effective income tax rate are as follows (in thousands, except percentages):

---

| | | |
|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** |
| | **January 2,<br>2026** | **January 3,<br>2025** |
| Income tax expense (benefit) | $822 | $(2407) |
| Effective income tax rate | 1.7% | 1.4% |

---

The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for the three months ended January 2, 2026 was primarily driven by favorable share-based compensation and our research and development ("R&D") tax credits. The difference between the U.S. federal statutory income tax rate of 21% and our effective income tax rate for the three months ended January 3, 2025 was primarily driven by the non-deductibility of the loss on extinguishment of debt and favorable share-based compensation and R&D tax credits, partially offset by global intangible low taxed income ("GILTI").

We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making this determination, we consider available positive and negative evidence. We look at factors that may impact the

------

valuation of our deferred tax assets including results of recent operations, future reversals of existing taxable temporary differences, projected future taxable income and tax-planning strategies.

The July 4, 2025 Bill permits deduction of applicable domestic research and development costs in the year they are incurred and no longer requires the deferral and amortization of these costs over five years, among other changes. This change is effective beginning in our fiscal year ending October 2, 2026. The July 4, 2025 Bill permits the acceleration of our unamortized balance of domestic research and development expenses which were previously deferred.

There were no unrecognized tax benefits as of January 2, 2026 and October 3, 2025. It is our policy to recognize any interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the fiscal quarters ended January 2, 2026 and January 3, 2025, we did not make any accrual or payment of interest or penalties.

**17. SEGMENT REPORTING, GEOGRAPHIC AND SIGNIFICANT CUSTOMER INFORMATION**

We have one reportable operating segment that designs, develops, manufactures and markets semiconductors and modules. The determination of the number of reportable operating segments is based on the chief operating decision maker's ("CODM") use of financial information provided for the purposes of assessing performance and making operating decisions. The Company's CODM is its President and Chief Executive Officer and Chair of the Board. In evaluating financial performance and making operating decisions, the CODM primarily uses consolidated metrics. The Company assesses its determination of operating segments at least annually. We continue to evaluate our internal reporting structure, changes to our business and the potential impact of these changes on our segment reporting. The accounting policies of the single operating segment are the same as those described in the summary of significant account policies.

The CODM uses consolidated gross profit and net income (loss) to assess financial performance against prior periods and our competitors, to decide how to allocate resources and to evaluate income generated from segment assets in deciding whether to reinvest profits into our operations or into other parts of the entity, such as for acquisitions or other investments. The measure of segment assets is reported on the balance sheet as total assets. Financial forecasts and budget to actual results used by the CODM to assess performance and allocate resources, as well as those used for strategic decisions related to headcount and capital expenditures are also reviewed on a consolidated basis.

The following table presents a summary of consolidated net (loss) income inclusive of significant segment expenses and other expense information provided to the CODM (in thousands):

**Description of Our Revenue**

*Revenue.* Our revenue is derived from sales of high-performance RF, microwave, millimeter wave, optical and photonic semiconductor products. We design, integrate, manufacture and package differentiated, semiconductor-based products that we sell to customers through our direct sales organization, our network of independent sales representatives and our distributors.

We believe the primary drivers of our future revenue growth will include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• continued growth in the demand for high-performance analog, digital and optical semiconductors in our three primary markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• introducing new products using advanced technologies, added features, higher levels of integration and improved performance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increasing content of our semiconductor solutions in customers' systems through cross-selling our product lines;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• leveraging our core strength and leadership position in standard, catalog products that service all of our end applications; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• engaging early with our lead customers to develop custom and standard products.

Our core strategy is to develop and innovate high-performance products that address our customers' most difficult technical challenges in our primary markets: I&D, Data Center and Telecom.

We expect our revenue in the I&D market to be driven by the expanding product portfolio that we offer which services applications such as test and measurement, space-related electronics, civil and military radar, industrial, automotive, scientific and medical applications, further supported by growth in applications for our multi-market catalog products.

We expect our revenue in the Data Center market to be driven by the adoption of higher speed processing technologies and the upgrade of data center architectures to 100G, 200G, 400G, 800G, 1.6T and 3.2T interconnects, which we expect will drive adoption of higher speed optical and photonic components.

We expect our revenue in the Telecom market to be driven by 5G deployments, with continued upgrades and expansion of communications equipment, SATCOM networks and increasing adoption of our high-performance RF, millimeter wave, optical and photonic components.

**Critical Accounting Policies and Estimate**s

Our discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements. The preparation of financial statements, in conformity with GAAP, requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the reported amounts of revenue and expenses during the reporting period and disclosure of contingent assets and liabilities at the date of the financial statements. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty and could be material if our actual or expected experience were to change unexpectedly. On an ongoing basis, we re-evaluate our estimates and judgments.

We base our estimates and judgments on our historical experience and on other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making the judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates and material effects on our operating results and financial position may result. The accounting policies which our management believes involve the most significant application of judgment or involve complex estimation, are inventories and associated reserves; revenue reserves; business combinations; goodwill and intangible asset valuation; share-based compensation valuations and income taxes.

*Business combinations*

We apply significant estimates and judgments in order to determine the fair value of the identified tangible and intangible assets acquired, liabilities assumed and goodwill recognized in business combinations. The value of all assets and liabilities are recognized at fair value as of the acquisition date using a market participant approach. In measuring the fair value, we utilize a number of valuation techniques. When determining the fair value of property and equipment acquired, generally we must estimate the cost to replace the asset with a new asset taking into consideration such factors as age, condition and the economic useful life of the asset. When determining the fair value of intangible assets acquired, typically determined using a discounted cash flow valuation method, we use assumptions such as the timing and amount of future cash flows, discount rates, weighted average cost of capital and estimated useful lives. These assessments can be significantly affected by our judgments.

*Goodwill and intangible asset valuation*

Significant management judgment is required in our valuation of goodwill and intangible assets, many of which are based on the creation of forecasts of future operating results that are used in the valuation, including (i) estimation of future cash

------

flows, (ii) estimation of the long-term rate of growth for our business, (iii) estimation of the useful life over which cash flows will occur, (iv) terminal values, if applicable, and (v) the determination of our weighted average cost of capital, which helps determine the discount rate. It is possible that these forecasts may change, and our performance projections included in our forecasts of future results may prove to be inaccurate. The value of our goodwill and purchased intangible assets could also be impacted by future adverse changes, such as a decline in the valuation of technology company stocks, including the valuation of our common stock, or a significant slowdown in the worldwide economy or in the semiconductor industry.

For additional information related to these and other accounting policies refer to *Note 2 - Summary of Significant Accounting Policies* to our Consolidated Financial Statements included in Item 8 of Part II, "Financial Statements and Supplementary Data," of the 2025 Annual Report on Form 10-K and *Note 1 - Basis of Presentation and Summary of Significant Accounting Policies* to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

*Income taxes*

We are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our current tax exposure and assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our Consolidated Balance Sheets. We then assess the likelihood that our deferred tax assets will be recovered from future taxable income within the relevant jurisdiction. To the extent we believe that recovery is not likely, we must establish a valuation allowance. We provide valuation allowances for certain deferred tax assets where it is more likely than not that any portion will not be realized.

The application of tax laws and regulations to calculate our tax liabilities is subject to legal and factual interpretation, judgment and uncertainty in a multitude of jurisdictions. Tax laws and regulations themselves are subject to change as a result of changes in fiscal policy, changes in legislation, the evolution of regulations, including the July 4, 2025 Bill, as well as court rulings. We recognize potential liabilities for anticipated tax audit matters in the United States and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes and interest will be due. We record an amount as an estimate of probable additional income tax liability at the largest amount that we feel is more likely than not, based upon the technical merits of the position, to be sustained upon audit by the relevant tax authority.

---

In the three months ended January 2, 2026, our I&D market revenue increased by $20.3 million, or 20.9%, compared to the three months ended January 3, 2025. The increase in the three months ended January 2, 2026 was primarily driven by revenue growth from defense programs.

In the three months ended January 2, 2026, our Data Center market revenue increased by $20.5 million, or 31.4%, compared to the three months ended January 3, 2025. The increase in the three months ended January 2, 2026 was primarily driven by higher sales of high-performance analog, coherent and lightwave Data Center products primarily supporting high speed data rates from 100G to 1.6T.

In the three months ended January 2, 2026, our Telecom market revenue increased by $12.7 million, or 22.9%, compared to the three months ended January 3, 2025. The increase in the three months ended January 2, 2026 was primarily driven by higher sales of products for 5G, broadband access and SATCOM applications.

Certain areas of our end markets continue to be negatively impacted by macroeconomic and geopolitical conditions, which we expect may result in weaker near-term demand for our products across all three of our primary markets. In addition, we could be negatively affected by any weakening of global economic conditions, including as a result of the evolving impacts from tariffs, sanctions, obtaining required licenses or other trade tensions (including implementation of new tariffs or retaliatory trade measures).

*Gross profit.* Gross margin was 55.9% and 53.7% for the three months ended January 2, 2026 and January 3, 2025, respectively. Gross profit increased by $34.7 million, or 29.6%, to $151.8 million, or 55.9% of our revenue, for the three months ended January 2, 2026, compared to $117.1 million, or 53.7% of our revenue, for the three months ended January 3, 2025. Gross profit increased primarily as a result of higher sales, lower intangible asset amortization and share-based compensation expense, partially offset by increases in employee-related costs, due to additional headcount from the RTP Fab, and higher maintenance expense.

*Research and development.* Research and development expense increased by $6.1 million, or 10.1%, to $66.5 million, or 24.5% of our revenue, for the three months ended January 2, 2026, compared to $60.4 million, or 27.7% of our revenue, for the three months ended January 3, 2025. Research and development expense increased in the three months ended January 2, 2026 primarily due to employee-related costs, including increases in headcount, and depreciation expense.

*Selling, general and administrative.* Selling, general and administrative expense increased by $2.8 million or 7.2%, to $42.0 million or 15.5% of our revenue in the three months ended January 2, 2026, compared to $39.2 million, or 18.0% of our revenue, for the three months ended January 3, 2025. Selling, general, and administrative expense increased in the three months ended January 2, 2026 primarily due to an increase in employee-related costs, partially offset by lower intangible asset amortization.

*Interest income.* In the three months ended January 2, 2026, interest income was $8.0 million, compared to $7.0 million for the three months ended January 3, 2025. The increase for the three months ended January 2, 2026 is primarily due to an increase in short-term investments.

*Loss on extinguishment of debt.* In the three months ended January 3, 2025, we recognized a $193.1 million loss on exchange of our 2026 Convertible Notes. See *Note 10 - Debt* to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q for additional information.

| Income tax expense (benefit) | $822 | $(2407) |
| Effective income tax rate | 1.7% | 1.4% |

---

Our estimated annual effective tax rate for the fiscal year ending October 2, 2026 is expected to be approximately 16.2%, which reflects the statutory rate adjusted for expected tax credits, primarily for R&D. This effective tax rate does not reflect the adjustment for any discrete tax matters arising during the year, such as the excess deduction related to share-based compensation. The actual effective income tax rate for the quarter ended January 2, 2026 was reduced by excess tax benefits related to share-based compensation.

The effective income tax rate for the quarter ended January 3, 2025 was impacted by the non-deductibility of the charge for extinguishment of debt as well as excess tax benefits related to share-based compensation.

For additional information refer to *Note 15 - Income Taxes* to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

***Cash Flow from Operating Activities***

Our cash flow from operating activities for the three months ended January 2, 2026 of $42.9 million consisted of a net income of $48.8 million, which included non-cash charges of $36.9 million, primarily related to share-based compensation expense of $22.1 million and depreciation and intangible asset amortization expense of $15.4 million and a net increase in working capital of $42.7 million. The net increase in working capital of $42.7 million was primarily driven by a decrease in accrued and other liabilities of $19.0 million, a decrease in accounts payable of $5.1 million and by an increase in accounts receivables of $11.4 million.

Our cash flow from operating activities for the three months ended January 3, 2025 of $66.7 million consisted of a net loss of $167.5 million, which included non-cash charges of $225.3 million, primarily related to loss on extinguishment of debt of $193.1 million, share-based compensation expense of $25.5 million and depreciation and intangible asset amortization expense of $16.0 million, and a net decrease to working capital of $8.9 million. The net decrease in working capital of $8.9 million was primarily driven by a decrease in accounts receivables of $14.9 million, partially offset by an increase in inventories of $4.6 million. The decrease in accounts receivable is primarily due to improved revenue linearity during the three months ended January 3, 2025.

***Cash Flow from Investing Activities***

Our cash flow provided by investing activities for the three months ended January 2, 2026 of $8.8 million consisted primarily of proceeds of $71.4 million for the sale and maturity of short term investments, offset by purchases of $45.7 million of short-term investments, capital expenditures of $12.9 million and purchases of software licenses of $4.3 million.

For additional information on the consideration paid for our acquisitions, see *Note 3 - Acquisitions* to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

***Cash Flow from Financing Activities***

During the three months ended January 2, 2026, our cash used in financing activities of $44.2 million was primarily related to $47.9 million of common stock withheld associated with employee taxes on vested equity awards, partially offset by $5.2 million of proceeds from stock option exercises and employee stock purchases.

During the three months ended January 3, 2025, our cash provided by financing activities of $30.1 million was primarily related to $86.6 million of proceeds from convertible notes and $4.5 million of proceeds from stock option exercises and employee stock purchases, partially offset by $37.9 million of common stock withheld associated with employee taxes on vested equity awards and $22.9 million of fees for the convertible note exchange and payments for debt issuance costs.

As of January 2, 2026, we held $119.6 million of cash and cash equivalents, primarily deposited with financial institutions, as well as $648.8 million of liquid short-term investments. The undistributed earnings of certain foreign subsidiaries are considered indefinitely reinvested for the periods presented and we do not intend to repatriate such earnings. We believe the decision to reinvest these earnings will not have a significant impact on our liquidity. As of January 2, 2026, cash held by our indefinitely reinvested foreign subsidiaries was $5.7 million, which, along with cash generated from foreign operations, is expected to be used in the support of international growth and working capital requirements as well as the repayment of certain intercompany loans.

Holders of the 2026 Convertible Notes were able to convert their notes prior to maturity, under certain conditions. In September 2025, holders exercised their right to convert $0.5 million of the notes. The transaction settled during the three months ended January 2, 2026 and we paid $0.5 million principal in cash and issued 2,610 shares of our common stock for the conversion premium. On or after December 15, 2025, holders of our 2026 Convertible Notes may convert their notes at their option at any time in multiples of $1,000 principal amount. As of December 15, 2025, we elected combination settlement, paying the principal in cash and settling the conversion premium in shares, for all future conversions. Conversion notices received on or after December 15, 2025 will be settled upon maturity of the 2026 Convertible Notes. We expect to pay down the principal of the 2026 Convertible Notes at maturity using cash and short-term investments on hand. For additional information on the 2026 Convertible Notes, see *Note 10 - Debt* to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

On January 14, 2025, we announced the execution of a preliminary, non-binding agreement with the CHIPS Program Office, which could provide for proposed direct funding from the U.S. Department of Commerce under the CHIPS Act of up to $70 million.

We plan to use our remaining available cash and cash equivalents and short-term investments for general corporate purposes, including working capital, payment on the 2026 Convertible Notes and 2029 Convertible Notes, or for the acquisition of or investment in complementary technologies, design teams, products and businesses. We believe that our cash and cash equivalents, short-term investments and cash generated from operations will be sufficient to meet our working capital requirements for at least the next twelve months. We may need to raise additional capital from time to time through the issuance and sale of equity or debt securities, and there is no assurance that we will be able to do so on favorable terms or at all.

As of January 2, 2026, we had no off-balance sheet arrangements.

For additional information related to our Liquidity and Capital Resources, see *Note 10 - Debt* to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

**Recent Accounting Pronouncements**

See *Note 1 - Basis of Presentation and Summary of Significant Accounting Policies* to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q for information about recent accounting pronouncements.

**ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

We are exposed to market risk in the ordinary course of business, which consists primarily of interest rate risk associated with our cash and cash equivalents and short-term investments, as well as foreign exchange rate risk.

------

*Interest rate risk.* The primary objectives of our investment activity are to preserve principal, provide liquidity and invest excess cash for an average rate of return. To minimize market risk, we maintain our portfolio in cash and diversified investments, which may consist of corporate bonds, bank deposits, money market funds, commercial paper and U.S. Treasury securities. The interest rates are variable and fluctuate with current market conditions. The risk associated with fluctuating interest rates is limited to this investment portfolio. We believe that a 1% change in interest rates would have a $7.7 million impact on our annual interest income, based on cash and cash equivalents and short-term investments balances as of January 2, 2026. We believe that a change in interest rates would not have a material impact on our results of operations, however, such change(s) could impact net income and earnings per share. We do not enter into financial instruments for trading or speculative purposes.

*Foreign currency risk.* To date, our international customer agreements have been denominated primarily in U.S. dollars. Accordingly, we have limited exposure to foreign currency exchange rates. The functional currency of a majority of our foreign operations continues to be in U.S. dollars with the remaining operations being local currency. Changes in the value of the U.S. dollar relative to other currencies could make our products more expensive, which could negatively impact demand in certain regions, reduce or delay customer orders, or otherwise negatively affect how customers do business with us. The effects of exchange rate fluctuations on the net assets of the majority of our operations are accounted for as transaction gains or losses. We believe that a change of 10% in such foreign currency exchange rates would not have a material impact on our financial position or results of operations.

We have entered into foreign currency exchange hedging contracts to reduce the impact of foreign currency changes on certain intercompany foreign currency denominated debt. These foreign currency forward contracts are entered into for periods consistent with currency transaction exposures, generally one month. They are not designated as cash flow or fair value hedges under ASC 815, *Derivatives and Hedging*. These forward contracts are marked-to-market with changes in fair value recorded to earnings. As of January 2, 2026, we had $47.0 million in notional forward foreign currency contracts, which were denominated in Euro and Yen. The fair value of these forward contracts is immaterial as of January 2, 2026.

**ITEM 4. CONTROLS AND PROCEDURES**

**Evaluation of Disclosure Controls and Procedures**

As of the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")). Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) were effective as of January 2, 2026.

**Changes in Internal Control over Financial Reporting**

There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**Limitations on Controls**

Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving the desired control objectives. Our management recognizes that any control system, no matter how well designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurance that its objectives will be met. Similarly, an evaluation of controls cannot provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.

**PART II—OTHER INFORMATION**

**ITEM 1. LEGAL PROCEEDINGS**

See *Note 13 - Commitments and Contingencies* to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q for information about our legal proceedings.

**ITEM 1A. RISK FACTORS**

Our business involves a high degree of risk. In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in Part I, "Item 1A. Risk Factors" in our 2025 Annual Report on Form 10-K, which could materially affect our business, financial condition or future results. As of the date of this Quarterly Report on Form 10-Q, there have been no material changes in any of the risk factors described in our 2025 Annual Report on Form 10-K, except as noted below.

***Our internal and external manufacturing, assembly and test model subjects us to various manufacturing and supply risks.***

We operate leased semiconductor wafer processing and manufacturing facilities at our headquarters in Lowell, Massachusetts, and at our Ann Arbor, Michigan, RTP, North Carolina and Limeil-Brévannes, France sites. These facilities are also important internal design, assembly and test facilities. We maintain other internal assembly and test operation facilities as well, including leased sites in Hamilton, New Jersey, Morgan Hill, California, Nashua, New Hampshire, and Hsinchu, Taiwan. We also use multiple external foundries for outsourced semiconductor wafer supply, as well as multiple domestic and Asian assembly and test suppliers to assemble and test our products. A number of factors will affect the future success of these internal manufacturing facilities and outsourced supply and service arrangements, including the level of demand for our products; our ability to expand and contract our facilities and purchase commitments in a timely and cost-effective manner; our ability to generate revenue in amounts that cover the significant fixed costs of operating our facilities; our ability to qualify our facilities for new products and process technologies in a timely manner and avoid complications; the availability of raw materials; the availability and continued operation of key equipment; our manufacturing cycle times and yields; political and economic risks; the occurrence of natural disasters, pandemics, acts of terrorism, armed conflicts or unrest impacting our facilities and those of our outsourced suppliers; our ability to hire, train, manage and retain qualified production personnel; our compliance with applicable environmental and other laws and regulations; our ability to avoid prolonged periods of downtime or high levels of scrap in our and our suppliers' facilities for any reason; and our ability to negotiate renewals to our existing lease agreements on favorable terms and without disruption to our wafer processing and manufacturing and internal assembly and test operations at our sites where such activities take place. In addition, certain of our manufacturing operations require a continuous supply of critical materials, including various precious metals, exotic gases and chemicals, wafer substrate materials such as silicon, gallium arsenide (GaAs), gallium nitride (GaN), silicon carbide (SiC), indium phosphide (InP), and high-purity source materials such as gallium, germanium, arsenic, indium, aluminum, which we obtain from a limited number of qualified suppliers. The availability of these materials could become constrained due to increased global demand and limited global production capacity, geopolitical factors, supply chain disruptions and export control restrictions imposed by domestic or foreign governments. Any shortage, export restriction or license denial, extended lead times, price increases or quality issues with these materials could delay our production, increase our costs and prevent us from fulfilling customer orders. The effectiveness of our supply chain could be adversely affected by such issues and have a material adverse effect on our business, financial condition and results of operations.

**ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS**
