Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures We have performed an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the Exchange Act). Based on that evaluation, our management, including our CEO and CFO, concluded that our disclosure controls and procedures were effective as of December 31, 2022 to provide reasonable assurance that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Such disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed is accumulated and communicated to our management, including our CEO and CFO, to allow timely decisions regarding required disclosures. Changes in Internal Control over Financial Reporting There was no change in our internal controls during the fiscal quarter ended December 31, 2022 that materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting. Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system was designed to provide reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of published financial statements. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2022. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (2013 framework). Based on our assessment we concluded that, as of December 31, 2022, our internal control over financial reporting is effective based on those criteria. Our independent registered public accounting firm, Ernst & Young LLP, issued an attestation report on our internal control over financial reporting. This report appears on page F-3. Item 9B.

Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Silicon Laboratories Inc. (the Company) as of December 31, 2022 and January 1, 2022, the related consolidated statements of income, comprehensive income, changes in stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and January 1, 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 1, 2023 expressed an unqualified opinion thereon. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. ​ F- 1 Table of Contents Recognition of Variable Consideration ​ Description of the matter As described in Note 2 of the consolidated financial statements, the transaction price for sales reflects the Company’s expectations about the consideration it will be entitled to receive and may include fixed or variable amounts. Variable consideration primarily includes sales made to distributors under agreements allowing certain rights of return, referred to as stock rotation, and credits issued to the distributor due to price protection. The Company uses significant estimates to determine the expected variable consideration. Variable consideration that does not meet revenue recognition criteria is deferred and a revenue returns liability is recorded. The variable consideration estimate considers both the likelihood of a return and the amount of potential price concession. ​ ​ Auditing management’s variable consideration estimates relating to the pricing concessions and returns liability was judgmental because the calculations involve subjective management assumptions about the estimates of expected future price concessions and product returns. For example, the estimated variable consideration included in the transaction price reflects management’s evaluation of contractual terms, historical experience, assumptions about future economic conditions and the quantity of products distributors are expected to sell. Changes in those assumptions can have a material effect on the amount of variable consideration recognized. How we addressed the matter in our audit ​ We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the measurement and valuation of the variable consideration recognized. For example, we tested controls over management’s review of the variable consideration methodology, the significant assumptions and the historical data utilized in the estimate for assumed expected price concessions and product returns. To test the variable consideration recognized as revenue we performed audit procedures that included, among others, an evaluation of the Company’s methodology and significant assumptions and estimates and tested the completeness and accuracy of the historical data utilized in the estimates. In our assessment of the methodology, we considered changes in the business, changes in pricing assumptions, and evaluated significant assumptions used by management by comparison to current trends and recent transactions. We also evaluated the accuracy of management’s assumed price concessions and product returns from prior periods by comparing to subsequent actual activity. ​ ​ /s/ Ernst & Young LLP ​ ​ We have served as the Company’s auditor since 1996. ​ Austin, Texas ​ February 1, 2023 ​ ​ ​ ​ ​ F- 2 Table of Contents Report of Independent Registered Public Accounting Firm The Board of Directors and Stockholders of Silicon Laboratories Inc. Opinion on Internal Control Over Financial Reporting We have audited Silicon Laboratories Inc.’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Silicon Laboratories Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of Silicon Laboratories Inc. as of December 31, 2022 and January 1, 2022, the related consolidated statements of income, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes and our report dated February 1, 2023 expressed an unqualified opinion thereon. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process 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. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s 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. ​ /s/ Ernst & Young LLP ​ ​ Austin, Texas ​ February 1, 2023 ​ ​ ​ ​ F- 3 Table of Contents Silicon Laboratories Inc.

Notes to Consolidated Financial Statements December 31, 2022 1. Description of Business Silicon Laboratories Inc. (the “Company”), a Delaware corporation, is a leader in secure, intelligent wireless technology for a more connected world. Our integrated hardware and software platform, intuitive development tools, industry-leading ecosystem, and robust support help customers build advanced industrial, commercial, home, and life applications. The Company provides analog-intensive, mixed-signal solutions for use in a variety of electronic products in a broad range of applications for the Internet of Things (IoT) including connected home and security, industrial automation and control, smart metering, smart lighting, commercial building automation, consumer electronics, asset tracking and medical instrumentation. Within the semiconductor industry, the Company is known as a “fabless” company meaning that the integrated circuits (ICs) incorporated in its products are manufactured by third-party foundry semiconductor companies. On July 26, 2021, the Company sold its infrastructure and automotive business to Skyworks Solutions, Inc for $ 2.75 billion in cash. The financial results of the infrastructure and automotive business have been presented as discontinued operations in the Consolidated Financial Statements. See Note 3, Discontinued Operations , for additional information. ​ 2. Significant Accounting Policies Basis of Presentation and Principles of Consolidation The Company prepares financial statements on a 52 - or 53 -week fiscal year that ends on the Saturday closest to December 31. Fiscal 2022 and 2021 had 52 weeks. Fiscal 2020 had 53 weeks with the extra week occurring in the first quarter of the year. Fiscal 2022, 2021 and 2020 ended on December 31, 2022, January 1, 2022 and January 2, 2021, respectively. The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Foreign Currency Transactions The Company’s foreign subsidiaries are considered to be extensions of the U.S. Company. The functional currency of the foreign subsidiaries is the U.S. dollar. Accordingly, gains and losses resulting from remeasuring transactions denominated in currencies other than U.S. dollars are included in interest income and other, net in the Consolidated Statements of Income. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Among the significant estimates affecting the financial statements are those related to inventories, goodwill, acquired intangible assets, other long-lived assets, revenue recognition, stock-based compensation and income taxes. Actual results could differ from those estimates, and such differences could be material to the financial statements. The Company periodically reviews the assumptions used in its financial statement estimates. Fair Value of Financial Instruments The fair values of the Company’s financial instruments are recorded using a hierarchical disclosure framework based upon the level of subjectivity of the inputs used in measuring assets and liabilities. The three levels are described below: Level 1 - Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 - Inputs other than Level 1 that are directly or indirectly observable, such as quoted prices for similar assets or liabilities and quoted prices in less active markets. Level 3 - Inputs are unobservable for the asset or liability and are developed based on the best information available in the circumstances, which might include the Company’s own data. F- 9 Table of Contents Silicon Laboratories Inc. Notes to Consolidated Financial Statements (Continued) December 31, 2022 2. Significant Accounting Policies (Continued) Cash and Cash Equivalents Cash and cash equivalents consist of cash deposits, money market funds and investments in debt securities with original maturities of ninety days or less when purchased. Investments The Company’s investments typically have original maturities greater than ninety days as of the date of purchase and are classified as available-for-sale securities. Investments in available-for-sale securities are reported at fair value, with unrealized gains and losses, net of tax, recorded as a component of accumulated other comprehensive loss in the Consolidated Balance Sheet. Investments in which the Company has the ability and intent, if necessary, to liquidate in order to support its current operations (including those with contractual maturities greater than one year from the date of purchase) are classified as short-term. The Company reviews its available-for-sale investments as of the end of each reporting period for declines in fair value based on the specific identification method. The Company records an allowance for credit loss when a decline in fair value is due to credit-related factors. The Company considers various factors in determining whether an investment is impaired, including the severity of the impairment, changes in underlying credit ratings, forecasted recovery, its intent to sell or the likelihood that it would be required to sell the investment before its anticipated recovery in market value and the probability that the scheduled cash payments will continue to be made. When the Company concludes that a credit-related impairment has occurred, the Company assesses whether it intends to sell the security or if it is more likely than not that it will be required to sell the security before recovery. If either of these two conditions is met, the Company recognizes a charge in earnings equal to the entire difference between the security’s amortized cost basis and its fair value. If the Company does not intend to sell a security and it is not more likely than not that it will be required to sell the security before recovery, the unrealized loss is separated into an amount representing the credit loss, which is recognized in earnings, and the amount related to all other factors, which is recorded in accumulated other comprehensive loss. In addition, the Company has made equity investments in non-publicly traded companies. Equity investments in which the Company does not have control, but has the ability to exercise significant influence over operating and financial policies, are accounted for using the equity method. The Company’s proportionate share of income or loss is recorded in equity-method earnings in the Consolidated Statements of Income. The Company has elected to use the measurement alternative under Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, to value non-marketable equity investments that do not have readily determinable fair values. Under the alternative, these non-marketable equity investments are recorded at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes of the same or similar securities in observable transactions. The Company periodically reviews its equity investments for declines in fair value based on the specific identification method and writes down investments to their estimated fair values when it determines that a decline has occurred. Derivative Financial Instruments The Company uses derivative financial instruments to manage certain exposures to the variability of foreign currency exchange rates. The Company’s objective is to offset increases and decreases in expenses resulting from these exposures with gains and losses on the derivative contracts, thereby reducing volatility of earnings. The Company does not use derivative contracts for speculative or trading purposes. The Company recognizes derivatives, on a gross basis, in the Consolidated Balance Sheet at fair value. Cash flows from derivatives are classified according to the nature of the cash receipt or payment in the Consolidated Statement of Cash Flows. The Company also uses foreign currency forward contracts to reduce the earnings impact that exchange rate fluctuations have on non-U.S. dollar balance sheet exposures. The Company does not apply hedge accounting to these foreign currency forward contracts. F- 10 Table of Contents Silicon Laboratories Inc. Notes to Consolidated Financial Statements (Continued) December 31, 2022 2. Significant Accounting Policies (Continued) Inventories Inventories are stated at the lower of cost, determined using the first-in, first-out method, or net realizable value. The Company writes down the carrying value of inventory to net realizable value for estimated obsolescence or unmarketable inventory based upon assumptions about the age of inventory, future demand and market conditions. Inventory impairment charges establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable. Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the useful lives of the assets ranging from three to fifteen years . Leasehold improvements are depreciated over the lease term or their useful life, whichever is shorter. The Company owns the facilities for its headquarters in Austin, Texas. The buildings are located on land which is leased through 2099 from a third party. The rents for these ground leases were prepaid for the term of the leases. The buildings and leasehold interest in ground leases are being depreciated on a straight-line basis over their estimated useful lives of 40 years and 86 years , respectively. Business Combinations The Company records business combinations using the acquisition method of accounting and, accordingly, allocates the fair value of acquisition consideration to the assets acquired and liabilities assumed based on their fair values at the acquisition date. The excess of the fair value of purchase consideration over the fair value of the assets acquired and liabilities assumed is recorded as goodwill. The results of operations of the businesses acquired are included in the Company’s consolidated results of operations beginning on the date of the acquisition. Long-Lived Assets Purchased intangible assets are stated at cost, net of accumulated amortization, and are amortized using the straight-line method over their estimated useful lives, ranging from five to twelve years . Fair values are determined primarily using the income approach, in which the Company projects future expected cash flows and applies an appropriate discount rate. Long-lived assets “held and used” by the Company are reviewed for impairment whenever events or changes in circumstances indicate that their net book value may not be recoverable. When such factors and circumstances exist, the Company compares the projected undiscounted future cash flows associated with the related asset or group of assets over their estimated useful lives against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets and is recorded in the period in which the determination was made. The Company tests goodwill for impairment annually as of the first day of its fourth fiscal quarter and in interim periods if events occur that would indicate that the carrying value of goodwill may be impaired. The Company assesses goodwill for impairment by comparing the fair value of the reporting unit to its carrying amount. In determining fair value, several valuation methodologies are allowed, although quoted market prices are the best evidence of fair value. If the fair value of the reporting unit is less than its carrying amount, an impairment loss is recognized equal to that excess amount. ​ F- 11 Table of Contents Silicon Laboratories Inc. Notes to Consolidated Financial Statements (Continued) December 31, 2022 2. Significant Accounting Policies (Continued) Leases At the commencement date of a lease, the Company recognizes a liability to make lease payments and an asset representing the right to use the underlying asset during the lease term. The lease liability is measured at the present value of lease payments over the lease term. As its leases typically do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date taking into consideration necessary adjustments for collateral, depending on the facts and circumstances of the lessee and the leased asset, and term to match the lease term. The right-of-use (“ROU”) asset is measured at cost, which includes the initial measurement of the lease liability and initial direct costs incurred by the Company and excludes lease incentives. Lease liabilities are recorded in other current liabilities and other non-current liabilities. ROU assets are recorded in other assets, net. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease costs are recognized on a straight-line basis over the lease term. Lease agreements that contain both lease and non-lease components are generally accounted for separately. Revenue Recognition Revenue is recognized when control of the promised goods or services is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Substantially all of the Company’s contracts with customers contain a single performance obligation, the sale of mixed-signal integrated circuit (IC) products. This performance obligation is satisfied when control of the product is transferred to the customer, which typically occurs upon delivery. Unsatisfied performance obligations primarily represent contracts for products with future delivery dates. The Company has opted to not disclose the amount of unsatisfied performance obligations as these contracts have original expected durations of less than one year . The transaction price reflects the Company’s expectations about the consideration it will be entitled to receive from the customer and may include fixed or variable amounts. Variable consideration primarily includes sales made to distributors under agreements allowing certain rights of return, referred to as stock rotation, and credits issued to the distributor due to price protection. The Company estimates variable consideration at the most likely amount to which it expects to be entitled. The estimate is based on information available to the Company, including recent sales activity and pricing data. The Company applies a constraint to its variable consideration estimate which considers both the likelihood of a return and the amount of a potential price concession. Variable consideration that does not meet revenue recognition criteria is deferred. The Company records a right of return asset in prepaid expenses and other current assets for the costs of distributor inventory not meeting revenue recognition criteria. A corresponding deferred revenue and returns liability amount is recorded for unrecognized revenue associated with such costs. The Company’s products carry a one-year replacement warranty. Payments are typically due within 30 days of invoicing and do not include a significant financing component. Shipping and Handling Shipping and handling costs are classified as a component of cost of revenues in the Consolidated Statements of Income. Stock-Based Compensation The Company has stock-based compensation plans, which are more fully described in Note 16, Stock-Based Compensation . The Company accounts for those plans using a fair-value method and recognizes the expense in its Consolidated Statement of Income. F- 12 Table of Contents Silicon Laboratories Inc. Notes to Consolidated Financial Statements (Continued) December 31, 2022 2. Significant Accounting Policies (Continued) Research and Development Research and development costs are expensed as incurred. Research and development expense consists primarily of personnel-related expenses, including stock-based compensation, as well as new product masks, external consulting and services costs, equipment tooling, equipment depreciation, amortization of intangible assets, and an allocated portion of our occupancy costs. Assets purchased to support the Company’s ongoing research and development activities are capitalized when related to products which have achieved technological feasibility or have an alternative future use, and are amortized over their estimated useful lives. Advertising Advertising costs are expensed as incurred. Advertising expenses were not material for any of the periods presented. Income Taxes The Company accounts for income taxes using the liability method whereby deferred tax asset and liability account balances are determined based on differences between the financial reporting and the tax bases of assets and liabilities and are measured using the enacted tax laws and related rates that will be in effect when the differences are expected to reverse. These differences result in deferred tax assets and liabilities, which are included in the Company’s Consolidated Balance Sheets. The Company then assesses the likelihood that the deferred tax assets will be realized. A valuation allowance is established against deferred tax assets to the extent the Company believes that it is more likely than not that the deferred tax assets will not be realized, taking into consideration the level of historical taxable income and projections for future taxable income over the periods in which the temporary differences are deductible. Uncertain tax positions must meet a more-likely-than-not threshold to be recognized in the financial statements and the tax benefits recognized are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon final settlement. See Note 18, Income Taxes , for additional information. Adoption of New Accounting Standard Convertible Instruments The Company adopted FASB ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40) , on January 2, 2022, the first day of its fiscal year ended December 31, 2022. The Company elected the modified retrospective transition method of adoption at the beginning of the period of adoption through a cumulative-effect adjustment. Prior periods have not been adjusted. The following reflects the material changes recorded in connection with the cumulative-effect adjustment (in thousands): ​ ​ ​ ​ ​ ​ ​ Increase Financial Statement Line Item (Decrease) Current portion of convertible debt, net ​ $ 76,991 Other non-current liabilities ​ $ ( 17,028 ) Retained earnings ​ $ ( 59,963 ) ​ The primary impact of the Company’s adoption of ASU 2020-06 was to increase the carrying value of its convertible debt, representing the unamortized debt discount, and reduce deferred tax liabilities related to convertible debt. The adoption reduced reported interest expense recorded in connection with convertible debt, which increased basic earnings per share and diluted earnings per share by $ 0.47 and $ 0.46 , respectively, for the year ended December 31, 2022.

Discontinued Operations On July 26, 2021, the Company sold its infrastructure and automotive business to Skyworks Solutions, Inc. for $ 2.75 billion in cash. The financial results of the infrastructure and automotive business, which are readily distinguishable from other components of the Company, have been presented as discontinued operations in the Consolidated Financial Statements because the sale represented a strategic shift for the Company. The following table presents the financial results of the infrastructure and automotive business (the “discontinued operations”) in the Company’s Consolidated Statements of Income (in thousands, except per share data): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ January 1, ​ January 2, ​ 2022 2021 Revenues ​ $ 233,918 ​ $ 375,749 Costs of revenues ​ 95,457 ​ ​ 143,068 Operating expenses ​ ​ 46,643 ​ ​ 87,293 Operating income from discontinued operations ​ 91,818 ​ ​ 145,388 Gain on sale of discontinued operations ​ ​ 2,423,161 ​ ​ — Income from discontinued operations before income taxes ​ ​ 2,514,979 ​ ​ 145,388 Provision for income taxes ​ 339,706 ​ ​ 17,372 Income from discontinued operations ​ $ 2,175,273 ​ $ 128,016 ​ ​ ​ ​ ​ ​ ​ Income from discontinued operations per share: ​ ​ ​ ​ Basic ​ $ 50.79 ​ $ 2.92 Diluted ​ $ 49.09 ​ $ 2.89 ​ Continuing Involvement In connection with the closing of the sale, the Company entered into certain ancillary agreements with Skyworks, including a Transition Services Agreement (“TSA”). Through the TSA, the Company has subleased certain premises to Skyworks and will provide or provides various temporary support services for three to eighteen months after the close of the transaction, depending on the service provided. Although the services provided under the TSA will generate continuing cash flows between the Company and Skyworks for the duration of the TSA, the amounts have not been nor are expected to be material to the ongoing operations of either entity. Fees received by the Company under the TSA were $ 5.2 million for fiscal 2022. ​ F- 14 Table of Contents Silicon Laboratories Inc.

Investments classified as Level 3 are valued using a discounted cash flow model. The assumptions used in preparing the discounted cash flow model include estimates for interest rates, amount of cash flows, expected holding periods of the securities and a discount to reflect the Company’s inability to liquidate the securities. The Company’s foreign currency derivative instruments are valued using discounted cash flow models. The assumptions used in preparing the valuation models include foreign exchange rates, forward and spot prices for currencies and market observable data of similar instruments. Contractual maturities of investments The Company’s available-for-sale investments are reported at fair value, with unrealized gains and losses, net of tax, recorded as a component of accumulated other comprehensive loss in the Consolidated Balance Sheet. The following summarizes the contractual underlying maturities of the Company’s available-for-sale investments at December 31, 2022 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair ​ ​ Cost ​ Value Due in one year or less ​ $ 462,096 ​ $ 454,957 Due after one year through ten years ​ ​ 243,957 ​ ​ 237,561 Due after ten years ​ ​ 2,755 ​ ​ 2,755 ​ ​ $ 708,808 ​ $ 695,273 ​ F- 16 Table of Contents Silicon Laboratories Inc.

The gross unrealized losses as of January 1, 2022 were due primarily to changes in market interest rates and the illiquidity of the Company’s auction-rate securities. ​ The Company records an allowance for credit loss when a decline in investment market value is due to credit-related factors. When evaluating an investment for impairment, the Company reviews factors such as the severity of the impairment, changes in underlying credit ratings, forecasted recovery, the Company’s intent to sell or the likelihood that it would be required to sell the investment before its anticipated recovery in market value and the probability that the scheduled cash payments will continue to be made. As of December 31, 2022, there were no material declines in the market value of available-for-sale investments due to credit-related factors. At December 31, 2022 and January 1, 2022, there were no material unrealized gains associated with the Company’s available-for-sale investments. F- 17 Table of Contents Silicon Laboratories Inc.

Fair Value of Financial Instruments (Continued) Level 3 fair value measurements The following summarizes the activity in Level 3 financial instruments for the years ended December 31, 2022 and January 1, 2022 (in thousands): Assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ December 31, ​ January 1, Auction Rate Securities 2022 2022 Beginning balance ​ $ 4,980 ​ $ 5,340 Sales (1) ​ ​ ( 6,000 ) ​ ​ — Loss recognized in earnings ​ ​ 300 ​ ​ — Gain (loss) included in other comprehensive income (loss) ​ 720 ​ ( 360 ) Ending balance ​ $ — ​ $ 4,980 (1) On May 31, 2022, the Company sold its prior remaining holding of auction-rate securities for $ 5.7 million. Fair values of other financial instruments The Company’s debt is recorded at cost, but is measured at fair value for disclosure purposes. The fair value of the Company’s convertible senior notes is determined using observable market prices. The notes are traded in less active markets and are therefore classified as a Level 2 fair value measurement. As of December 31, 2022 and January 1, 2022, the fair value of the notes was $ 671.9 million and $ 944.3 million, respectively. The Company’s other financial instruments, including cash, accounts receivable and accounts payable, are recorded at amounts that approximate their fair values due to their short maturities. 6. Derivative Financial Instruments The Company uses derivative financial instruments to manage certain exposures to the variability of foreign currency exchange rates. The Company’s objective is to offset increases and decreases in expenses resulting from these exposures with gains and losses on the derivative contracts, thereby reducing volatility of earnings. Cash Flow Hedges Foreign Currency Forward Contracts The Company may use foreign currency forward contracts to reduce the earnings impact that exchange rate fluctuations have on operating expenses denominated in currencies other than the U.S. dollar. Changes in the fair value of the contracts are recorded in accumulated other comprehensive loss in the Consolidated Balance Sheet and subsequently reclassified into earnings in the period during which the hedged transaction is recognized. The reclassified amount is reported in the same financial statement line item as the hedged item. If the foreign currency forward contracts are terminated or can no longer qualify as hedging instruments prior to maturity, the fair value of the contracts recorded in accumulated other comprehensive loss may be recognized in the Consolidated Statement of Income based on an assessment of the contracts at the time of termination. As of December 31, 2022, the Company held no such foreign currency forward contracts. The fair value of the contracts, contract gains or losses recognized in other comprehensive loss and amounts reclassified from accumulated other comprehensive loss into earnings were not material for any of the periods presented. ​ F- 18 Table of Contents Silicon Laboratories Inc. Notes to Consolidated Financial Statements (Continued) December 31, 2022 6. Derivative Financial Instruments (Continued) Non-designated Hedges Foreign Currency Forward Contracts The Company may use foreign currency forward contracts to reduce the earnings impact that exchange rate fluctuations have on non-U.S. dollar balance sheet exposures. The Company recognizes gains and losses on the foreign currency forward contracts in interest income and other, net in the Consolidated Statement of Income in the same period as the remeasurement loss and gain of the related foreign currency denominated asset or liability. The Company does not apply hedge accounting to these foreign currency forward contracts. As of December 31, 2022, the Company held no such foreign currency forward contracts. The fair value of the foreign contracts and contract gains and losses recognized in income were not material for any of the periods presented. 7.

Risks and Uncertainties Financial Instruments Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash equivalents, investments, accounts receivable and derivatives. The Company places its cash equivalents and investments primarily in municipal bonds, money market funds, corporate bonds, U.S. government securities, agency bonds, asset-back securities, variable rate demand notes, Yankee bonds and commercial paper. Concentrations of credit risk with respect to accounts receivable are primarily due to customers with large outstanding balances. The Company’s customers that accounted for greater than 10% of accounts receivable consisted of the following distributors: ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ January 1, ​ 2022 2022 Arrow Electronics 29 % 28 % Edom Technology ​ * ​ 18 % ​ * Less than 10% of accounts receivable The Company performs periodic credit evaluations of its customers’ financial condition and generally requires no collateral from its customers. The Company provides an allowance for expected credit losses based upon the net amount expected to be collected on such receivables. Losses have not been significant for any of the periods presented. As a result of its use of derivative instruments, the Company is exposed to the risk that its counterparties will fail to meet their contractual obligations. To mitigate this counterparty credit risk, the Company has a policy to enter into contracts with only selected major financial institutions. The Company periodically reviews and re-assesses the creditworthiness of such counterparties based on a variety of factors. Distributor Advances On sales to distributors, the Company’s payment terms often require the distributor to initially pay amounts owed to the Company for an amount in excess of their ultimate cost. The Company’s sales price to its distributors may be higher than the amount that the distributors will ultimately owe the Company because distributors often negotiate price reductions after purchasing the product from the Company and such reductions are often significant. These negotiated price discounts are not granted until the distributor sells the product to the end customer, which may occur after the distributor has paid the original invoice amount to the Company. Payment of invoices prior to receiving an associated discount can have an adverse impact on the working capital of the Company’s distributors. Accordingly, the Company has entered into agreements with certain distributors whereby it advances cash to the distributors to reduce the distributor’s working capital requirements. The advance amounts are based on the distributor’s inventory balance, and are adjusted quarterly. Such amounts are recorded in prepaid expenses and other current assets in the Consolidated Balance Sheet. The terms of these advances are set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand. The agreements governing these advances can be cancelled by the Company at any time. F- 20 Table of Contents Silicon Laboratories Inc. Notes to Consolidated Financial Statements (Continued) December 31, 2022 8. Risks and Uncertainties (Continued) Suppliers A significant portion of the Company’s products are fabricated by Taiwan Semiconductor Manufacturing Co. (TSMC) or Semiconductor Manufacturing International Corporation (SMIC). The inability of TSMC or SMIC to deliver wafers to the Company on a timely basis could impact the production of the Company’s products for a substantial period of time, which could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows. Customers The Company sells directly to end customers, distributors and contract manufacturers. Although the Company actually sells the products to, and is paid by, distributors and contract manufacturers, the Company refers to the end customer as its customer. None of the Company’s end customers accounted for greater than 10% of revenue during fiscal 2022, 2021 or 2020. The Company’s distributors that accounted for greater than 10% of revenue consisted of the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ December 31, ​ January 1, ​ January 2, ​ 2022 2022 2021 Arrow Electronics 33 % 28 % 28 % Edom Technology 17 % 18 % 19 % Sekorm ​ * ​ 12 % 14 % * Less than 10% of revenue ​ ​ 9. Acquisition Redpine Signals On April 28, 2020, the Company acquired the Wi-Fi and Bluetooth business of Redpine Signals for $ 316.8 million.

Debt 0.625 % Convertible Senior Notes On June 1, 2020, the Company completed a private placement of $ 535 million principal amount convertible senior notes (the “2025 Notes”). The 2025 Notes bear interest semi-annually at a rate of 0.625 % per year and mature on June 15, 2025. The 2025 Notes are convertible at a conversion rate of 8.1980 shares of common stock per $1,000 principal amount of the 2025 Notes, or approximately 4.4 million shares of common stock, which is equivalent to a conversion price of $ 121.98 per share. The conversion rate is subject to adjustment under certain circumstances. Holders may convert the 2025 Notes under the following circumstances: during any calendar quarter after the calendar quarter ended on September 30, 2020 if the closing price of the Company’s common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is greater than or equal to $ 159.51 per share, representing 130 % of the conversion price of the 2025 Notes (“the Sales Price Trigger”); during the five business day period after any ten consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98 % of the product of the closing sale price of our common stock and the conversion rate on each such trading day; if specified distributions or corporate events occur; if the 2025 Notes are called for redemption; or at any time after March 15, 2025. The Company may redeem all or any portion of the 2025 Notes, at its option, on or after June 20, 2023, if the last reported sale price of the Company’s common stock has been at least 130 % of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period. As of January 1, 2022, upon conversion, the 2025 Notes could be settled in cash, shares of the Company’s common stock or a combination of cash and shares, at the Company’s election. On January 2, 2022, the Company irrevocably elected cash settlement for the principal amount of the 2025 Notes. The Company intends to settle any excess value in shares in the event of a conversion. The 2025 Notes were classified as current liabilities at January 1, 2022 due to the Sales Price Trigger condition being met on January 1, 2022. The Sales Price Trigger condition was not met during fiscal 2022, therefore the net carrying amount of the 2025 Notes is now classified as a non-current liability. The principal balance of the 2025 Notes was initially separated into liability and equity components, and recorded at fair value. The excess of the principal amount of the liability component over its carrying amount represented the debt discount, which was amortized to interest expense over the term of the 2025 Notes using the effective interest method. With the Company’s adoption of ASU 2020-06 in fiscal 2022, the principal balance of the 2025 Notes is no longer separated between liability and equity components. This resulted in an increase to the carrying value of its convertible debt, representing the unamortized debt discount as of January 2, 2022, with an offsetting reduction in stockholders’ equity. The Company incurred debt issuance costs of $ 10.4 million, which were allocated to the liability and equity components in proportion to the allocation of the proceeds. Upon the adoption of ASU 2020-06, the equity component was reclassified to liabilities and remeasured to reflect cumulative amortization since the issuance of the 2025 Notes. The carrying amount of the 2025 Notes consisted of the following (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, January 1, ​ ​ 2022 ​ 2022 Liability component ​ ​ ​ Principal ​ $ 534,980 ​ $ 535,000 Unamortized debt discount ​ — ​ ( 78,519 ) Unamortized debt issuance costs ​ ( 5,407 ) ​ ( 5,882 ) Net carrying amount ​ $ 529,573 ​ $ 450,599 ​ ​ ​ ​ ​ ​ ​ Equity component ​ ​ ​ ​ Net carrying amount ​ $ — ​ $ 107,928 ​ The liability component of the 2025 Notes is recorded in convertible debt on the Consolidated Balance Sheet. Prior to the Company’s adoption of ASU 2020-06, the equity component of the 2025 Notes was recorded in stockholders’ equity. The effective interest rate for the liability component was 5.336 %.

The credit facility includes a $ 25 million letter of credit sublimit and a $ 10 million swingline loan sublimit. The Company also has an option to increase the size of the borrowing capacity by up to the greater of an aggregate of $ 250 million and 100 % of EBITDA of the last four fiscal quarters, plus an amount that would not cause a secured leverage ratio (funded debt secured by assets/EBITDA) to exceed 3.25 to 1.00, subject to certain conditions. The credit facility, other than swingline loans, will bear interest at the Eurodollar rate plus an applicable margin or, at the option of the Company, a base rate (defined as the highest of the Wells Fargo prime rate, the Federal Funds rate plus 0.50 % and the Eurodollar Base Rate plus 1.00 %) plus an applicable margin. Swingline loans accrue interest at the base rate plus the applicable margin for base rate loans. The applicable margins for the Eurodollar rate loans range from 1.00 % to 1.75 % and for base rate loans range from 0.00 % to 0.75 %, depending in each case, on the leverage ratio as defined in the credit facility. The credit facility contains various conditions, covenants and representations with which the Company must be in compliance in order to borrow funds and to avoid an event of default, including financial covenants that the Company must maintain a net leverage ratio (funded indebtedness/EBITDA) of no more than 4.25 to 1, a secured leverage ratio of no more than 3.50 to 1, and a minimum interest coverage ratio (EBITDA/interest payments) of no less than 2.50 to 1. As of December 31, 2022, the Company was in compliance with all covenants of the credit facility. The Company’s obligations under the credit facility are guaranteed by the Guarantors and are secured by a security interest in substantially all assets of the Company and the Guarantors. As of December 31, 2022, no amounts were outstanding on the credit facility. ​ F- 24 Table of Contents Silicon Laboratories Inc.

Notes to Consolidated Financial Statements (Continued) December 31, 2022 16. Stock-Based Compensation The Company has two active stock plans, the 2009 Stock Incentive Plan (the “2009 Plan”) and the 2009 Employee Stock Purchase Plan (the “2009 ESPP”) that have been amended and approved by shareholders from time to time. ● The 2009 Plan allows for grants of stock options, stock appreciation rights, performance shares, performance stock units, restricted stock units (RSUs), restricted stock awards (RSAs), performance-based stock units (PSUs) and other awards (collectively, “awards”). All awards deduct one share from the 2009 Plan shares available for issuance for each share granted. Awards granted under the 2009 Plan contain vesting provisions mostly ranging from three to four years . To the extent awards granted under the 2009 Plan terminate, expire, or lapse for any reason, or are settled in cash, shares subject to such awards will again be available for grant. ● The 2009 ESPP allows eligible employees to purchase a limited number of shares of the Company’s common stock at no less than 85 % of the fair market value of a share of common stock at prescribed purchase intervals during an offering period. Each offering period is comprised of a series of one or more successive and/or overlapping purchase intervals and has a maximum term of 27 months . 2009 Plan The Company granted to its employees 0.5 million, 0.6 million and 0.7 million shares of full value awards from the 2009 Plan during fiscal 2022, 2021 and 2020, respectively. Full value awards include RSUs, MSUs awards and PSUs. MSUs provide the rights to acquire a number of shares of common stock for no cash consideration based upon achievement of specified levels of market conditions. The requisite measurement period for these MSUs is also the vesting period, which is generally three years . MSUs granted in 2020 measured the relative performance of the total stockholders’ return of the Company against that of a selected benchmarked group of companies. The Company granted no MSUs in fiscal 2022 and 2021 and 82,000 MSUs in fiscal 2020. PSUs provide for the rights to acquire a number of shares of common stock for no cash consideration based upon the achievement of specified revenue or profitability objectives during the year. The requisite performance period of these PSUs is approximately three years from the date of grant. The Company granted 52,078 and 116,809 PSUs in fiscal 2022 and 2021, respectively, and no PSUs in fiscal 2020. 2009 ESPP The rights to purchase common stock granted under the 2009 ESPP are intended to be treated as either (i) purchase rights granted under an “employee stock purchase plan,” as that term is defined in Section 423(b) of the Internal Revenue Code (the “423(b) Plan”), or (ii) purchase rights granted under an employee stock purchase plan that is not subject to the terms and conditions of Section 423(b) of the Internal Revenue Code (the “Non-423(b) Plan”). The Company will retain the discretion to grant purchase rights under either the 423(b) Plan or the Non-423(b) Plan. During fiscal 2022, 2021 and 2020, the Company issued 109,000 , 146,000 and 177,000 shares, respectively, under the 2009 ESPP to its employees. The weighted-average fair value for purchase rights granted in fiscal 2022 under the 2009 ESPP was $ 37.70 per share. ​ F- 27 Table of Contents Silicon Laboratories Inc. Notes to Consolidated Financial Statements (Continued) December 31, 2022 16. Stock-Based Compensation (Continued) Accounting for Stock-Based Compensation Stock-based compensation costs are based on the fair values on the date of grant for awards under the 2009 Plan, and on the date of enrollment for grants under the 2009 ESPP. The fair values of stock awards (such as RSUs, PSUs and RSAs) are estimated based on their intrinsic values. The fair values of MSUs are estimated using a Monte Carlo simulation. The fair values of stock options and grants under the 2009 ESPP are estimated using the Black-Scholes option-pricing model. The fair values of all such stock-based grants are generally amortized on a straight-line basis over the vesting period of the grants. The Company estimates potential forfeitures of stock grants and adjusts compensation cost recorded accordingly. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures are recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of stock-based compensation expense to be recognized in future periods. The following table presents details of stock-based compensation costs recognized in the Consolidated Statements of Income (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ December 31, ​ January 1, ​ January 2, ​ 2022 2022 2021 Cost of revenues ​ $ 1,152 ​ $ 964 ​ $ 970 Research and development ​ 32,860 ​ 24,986 ​ 23,359 Selling, general and administrative ​ 26,498 ​ 30,892 ​ 25,125 ​ ​ 60,510 ​ 56,842 ​ 49,454 Income tax benefit ​ ( 5,980 ) ​ ( 954 ) ​ ( 3,694 ) Share-based compensation – continuing operations ​ ​ 54,530 ​ ​ 55,888 ​ ​ 45,760 Share-based compensation – discontinued operations, net ​ ​ — ​ ​ ( 2,007 ) ​ ​ 10,715 Total ​ $ 54,530 ​ $ 53,881 ​ $ 56,475 ​ The Company recorded $ 7.8 million in selling, general and administrative expense during fiscal 2021 in connection with the modification of certain equity awards. The modifications were pursuant to employee terminations. There were no other significant modifications made to any stock grants during fiscal 2022, 2021 or 2020. The Company had approximately $ 121.5 million of total unrecognized compensation cost related to equity grants as of December 31, 2022 that is expected to be recognized over a weighted-average period of approximately 2.1 years. There were no significant stock-based compensation costs capitalized into assets in any of the periods presented. F- 28 Table of Contents Silicon Laboratories Inc.

Notes to Consolidated Financial Statements (Continued) December 31, 2022 18. Income Taxes (Continued) The increase in the effective tax rate for fiscal 2022 was primarily due to the recognition of certain tax benefits for fiscal 2021 in discontinued operations under FASB ASU 2019-12, Simplifying the Accounting for Income Taxes, and the required adoption of new U.S. tax rules regarding the capitalization of research and experimental costs in fiscal 2022. The effective tax rate for fiscal 2021 decreased from fiscal 2020 primarily due to the adoption of ASU 2019-12 in 2021 and an increase in the beginning of year valuation allowance on deferred tax assets for state attribute carryforwards. Under ASU 2019-12, the income tax benefit of a loss from continuing operations should be recognized in discontinued operations if the Company would be unable to benefit from the loss without considering the income from discontinued operations. As such, tax benefits associated with losses incurred for fiscal 2021 were recognized in discontinued operations. Additionally, for fiscal 2021 there was an increase in the beginning of year valuation allowance on deferred tax assets for state attribute carryforwards as a result of changes in state tax estimates, primarily due to the divestiture of the infrastructure and automotive business. In fiscal 2021, tax on the gain from the divestiture of the infrastructure and automotive business of $ 346.9 million was recorded in discontinued operations, as well as additional tax benefits associated with discontinued operations of $ 7.2 million. In fiscal 2022, the Company revised its estimate of tax on the gain from the divestiture and recorded an associated net tax benefit of $ 2.2 million, which comprises the majority of the return to provision adjustment in the effective tax rate. The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. Under the Act, research and experimental expenditures incurred for tax years beginning after December 31, 2021 must be capitalized and amortized ratably over five or fifteen years for tax purposes, depending on where the research activities are conducted. The Company has elected to treat global intangible low-taxed income (GILTI) as a period cost, so the capitalization of research and experimental costs in GILTI increases the Company’s provision for income taxes. Additionally, the Act required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously deferred from U.S. income tax under U.S. tax law. The Company elected to pay the transition tax over the eight-year period provided in the Act. As of December 31, 2022, the unpaid balance of its transition tax obligation was $ 19.0 million, which is payable between April 2023 and April 2025. This was recorded as components of other current liabilities and other non-current liabilities in the Consolidated Balance Sheet in the amounts of $ 4.8 million and $ 14.2 million, respectively.

These carryforwards expire in fiscal years 2023 through 2031. Recognition of these loss and credit carryforwards is subject to an annual limit, which may cause them to expire before they are used. The Company also had state loss, state tentative minimum tax credit, and state research and development tax credit carryforwards of approximately $ 29.3 million, $ 0.1 million, and $ 12.2 million, respectively. Certain of these carryforwards expire in fiscal years 2025 through 2036, and others do not expire. Recognition of some of these loss and credit carryforwards is subject to an annual limit, which may cause them to expire before they are used. ​ F- 33 Table of Contents Silicon Laboratories Inc.

Income Taxes (Continued) A valuation allowance is established against a deferred tax asset when it is more likely than not that the deferred tax asset will not be realized. The Company maintains a valuation allowance with respect to certain deferred tax assets relating to state research and development tax credits, state net operating loss carryforwards and state alternative minimum tax credits.

The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes. These amounts were not material for any of the periods presented. Following the completion of the Norwegian Tax Administration (“NTA”) examination of the Company’s Norwegian subsidiary for income tax matters relating to fiscal years 2013 – 2016, the Company received an assessment from the NTA in December 2017 concerning an adjustment to its 2013 taxable income related to the pricing of an intercompany transaction. The Company is currently appealing the assessment. The adjustment to the pricing of the intercompany transaction results in approximately 141.3 million Norwegian kroner, or $ 14.3 million, additional Norwegian income tax. The Company disagrees with the NTA’s assessment and believes the Company’s position on this matter is more likely than not to be sustained. The Company plans to exhaust all available administrative remedies, and if unable to resolve this matter through administrative remedies with the NTA, the Company plans to pursue judicial remedies. The Company believes that it has accrued adequate reserves related to all matters contained in tax periods open to examination. Should the Company experience an unfavorable outcome in the NTA matter, however, such an outcome could have a material impact on its financial statements.
