We have audited the accompanying consolidated balance sheet of Silicon Laboratories Inc. and subsidiaries (the “Company”) as of January 3, 2026 and the related consolidated statements of operations, comprehensive loss, changes in stockholders’ equity, and cash flows, for the year ended January 3, 2026, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of January 3, 2026 and the results of its operations and its cash flows for the year ended January 3, 2026, in conformity with accounting principles generally accepted in the United States of America.

We have also 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 January 3, 2026, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 10, 2026, expressed an unqualified opinion on the Company’s internal control over financial reporting.

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 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 auditin 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 audit 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 audit 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 our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the 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.

Inventories – Inventory Valuation — Refer to Note 2 to the financial statements

Critical Audit Matter Description

Inventory is 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 if it is obsolete or unmarketable based upon the age of inventory or if quantities are in excess of customer demand. Inventory not identified to be written down due to aging is compared to an eighteen-month forecasted demand to identify potential excess inventory quantities on hand. Management estimates of forecasted demand is based on various assumptions, including but not limited to assumptions regarding product life cycles and market conditions. As of January 3, 2026, the Company’s inventory balance was $95.6 million.

We identified inventory valuation as a critical audit matter because of the significant assumptions management makes with regards to estimating the forecasted demand. Performing audit procedures to evaluate the reasonableness of management’s estimates of forecasted demand required a high degree of auditor judgment and increased audit effort.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to management’s estimates of forecasted demand used in the valuation of inventory included the following, among others:

•We tested the effectiveness of internal controls over management’s provisions for slow moving and obsolete inventories, including internal controls designed to review and approve forecasted demand and the underlying assumptions regarding product life cycles and market conditions.

•We evaluated management’s ability to accurately estimate forecasted demand by comparing estimates made in prior periods to the historical actual results for those same periods.

•We made inquiries of Company personnel including executive, sales and marketing, and operations personnel about product life cycles and market conditions and compared expectations to those included in the forecasted demand.

•We selected a sample of inventory products and tested the forecasted demand by comparing internal and external information (e.g., historical sales, customer backlog, communications with customers, product life cycles and market conditions, as applicable) with the Company’s forecast.

•We considered, when relevant, the existence of contradictory evidence based on reading of internal financial and operational information used by management and the board of directors, Company press releases, and analysts’ reports, as well as our observations and inquiries as to changes within the business and evidence obtained through other areas of the audit.
