Corporate Responsibility & ESG

Silicon Labs is a leading provider of silicon, software, and solutions for a smarter, more connected world. Our integrated hardware and software platform empowers developers to create wirelessly connected devices that are transforming industries, growing economies, and improving lives. Guided by our shared values, we strive to “do the right thing” for our employees, customers, shareholders, and communities. We integrate environmental, social, and governance (ESG) principles throughout our business, driven by our stakeholders, who help us identify and prioritize ESG-related issues. Silicon Labs routinely engages with our shareholders to better understand their ESG views, carefully considering the feedback we receive and acting when appropriate. While we devote resources to a wide range of ESG-related issues, our goals are focused in five strategic areas: employee wellbeing, product and services innovation, eco-efficient operations, climate change mitigation, and responsible supply chain based on a materiality assessment by stakeholders.

We report additional details on our ESG commitments and progress in our annual Corporate Sustainability Report, available at: https://www.silabs.com/corporate-responsibility.

Ensuring Ethical & Responsible Governance

At Silicon Labs, ESG Governance is a shared responsibility of the Board of Directors and Executive Management. Together, we prioritize climate-related risks and opportunities to focus our efforts where we will have the most impact – setting clear goals, tracking progress, and ensuring accountability.

To integrate ESG oversight across all parts of the company, Silicon Labs established an ESG Steering Committee with executive sponsorship by the Chief Financial Officer, the Chief Legal Officer, and the VP Strategy & Corporate Development. This steering committee meets monthly and is comprised of senior management and cross-functional personnel from various departments, including our ESG Coordinator, Investor Relations, Legal, People, Marketing, Operations, Quality, and others. The ESG Steering Committee sets the overall ESG strategy and meets monthly to oversee the company’s ESG priorities, goals, and disclosures.

The Board has tasked the Nominating and Corporate Governance (“NCG”) Committee to review issues and developments related to corporate governance, environmental and social matters. ESG Steering Committee and senior leadership provide quarterly updates to the NCG and at least annual updates to the Board. Together, the NCG and the ESG Steering Committee recommend associated ESG frameworks and standards to the Board.

The highest level of ESG oversight is with the Silicon Labs Board of Directors. At least annually, but often more frequently, the board reviews identified risks across a wide variety of focus areas including supply chain, macroeconomic fluctuations, cybersecurity, and climate-related related risks, and advises on action plans.

We’re committed to driving long-term change and accountability by incorporating our diversity, equity, and inclusion (DEI) objectives into our executive bonus plan and conducting an annual employee inclusion assessment to inform our action plans.

Advancing Responsible & Sustainable Operations

Sustainability is an integral part of everything we do. Responsible and sustainable practices are threaded throughout our everyday business operations, product design, and technology investments, in both our own internal operations and our relationships with suppliers and customers. We minimize resource use, reduce the environmental impact of our production processes, require working conditions in our supply chain are safe, and protect the security of our technology infrastructure and data.

We strive to deliver products that meet environmental regulations and requirements and have high standards for our global supply chain partners, prioritizing qualified suppliers who are socially and environmentally progressive. As a fabless semiconductor company, we are committed to working closely with our suppliers to understand climate-related impacts throughout our supply chain as we strive to reduce our carbon footprint.

All votes will be tabulated by the inspector of elections appointed for the meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes (i.e., a Proxy submitted by a broker or nominee specifically indicating the lack of discretionary authority to vote on the matter). Abstentions and broker non-votes will be counted as present for purposes of determining a quorum for the transaction of business but will not be counted for purposes of determining whether each proposal has been approved.

Proposal One: Election of Directors

General

The Board of Directors is divided into three classes, designated Class I, Class II and Class III, with staggered three-year terms. William P. Wood, a Class I Director, notified the Company of his decision not to stand for re-election at the Annual Meeting of Stockholders on April 20, 2023. His tenure as a member of the Board of Directors will be completed at the Annual Meeting. The term of office of the other Class I Directors, Navdeep Sooch, Robert J. Conrad and Nina Richardson will expire at this Annual Meeting. Messrs. Sooch and Conrad and Ms. Richardson have been nominated to continue as Class I Directors. The directors elected as Class I Directors at the Annual Meeting will each serve for a term of three years expiring at the 2026 annual meeting of stockholders, or until such director’s successor has been duly elected and qualified or until such director’s earlier death, resignation or removal.

The nominees for election have agreed to serve if elected, and management has no reason to believe that the nominees will be unavailable to serve. In the event the nominees are unable or decline to serve as directors at the time of the Annual Meeting, the Proxies will be voted for any nominees who may be designated by our present Board of Directors to fill the vacancies. Unless otherwise instructed, the Proxy holders will vote the Proxies received by them FOR the nominees named below.

Board Leadership/Independence

The Board of Directors separates the role of Chairman of the Board from the role of Chief Executive Officer. The Board of Directors has also designated Mr. Sadana as the Lead Director. The Lead Director’s duties include presiding over executive sessions of the Company’s independent directors and serving as principal liaison between the non-employee directors, the Chief Executive Officer and the Chairman of the Board on sensitive issues. The Board believes that the appointment of the Lead Director and the separation of the Chairman and Chief Executive Officer roles currently provides the most efficient and effective leadership model for the Company as it encourages free and open dialogue regarding competing views and provides for strong checks and balances. Specifically, the balance of powers among our Chief Executive Officer, Chairman of the Board and Lead Director facilitates the active participation of our independent directors and enables our Board of Directors to provide more effective oversight of management. The Board of Directors has determined that Messrs. Bock, Conrad, Lowe, Sadana, and Sooch and Mses. Richardson, Wyatt and Luther are each independent as defined in the applicable Marketplace Rules of the NASDAQ Stock Market, Inc. Independent directors met in executive session without the Chief Executive Officer and other non-independent directors present on four occasions during fiscal 2022.

Any member of our Board of Directors may resign at any time by delivering written notice to the Company. When a director resigns, a majority of the directors remaining in office shall have the power to fill the vacancy on the Board of Directors and the director so elected shall hold office for the unexpired portion of the term of the resigned director.

Committees and Meetings

During fiscal 2022, our Board of Directors held a total of six meetings. Our Board of Directors has an Audit Committee, Compensation Committee, Nominating and Corporate Governance Committee and a Corporate Development and Finance Committee. During fiscal 2022, each incumbent director attended or participated in at least 75% of the aggregate of (i) the meetings of the Board of Directors and (ii) the meetings held by all committees of the Board of Directors on which such director served.

Audit Committee. The Audit Committee is responsible for matters relating to the selection of our independent registered public accounting firm, the scope of the annual audits, the fees to be paid to the independent registered public accounting firm, the performance of our independent registered public accounting firm, compliance with our accounting and financial policies, and management’s procedures and policies relative to the adequacy of our internal accounting controls. The Committee also reviews the Company’s policies and practices with respect to risk management including cyber security risks. The members of the Audit Committee are Mr. Bock and Mses. Luther and Wyatt. Mr. Bock serves as Chairman of the Audit Committee. The Board of Directors has determined that Mr. Bock is qualified as an audit committee financial expert pursuant to Item 407 of Regulation S-K and as a financially sophisticated audit committee member under Rule 5605(c)(2)(A) of the Marketplace Rules of the NASDAQ Stock Market, Inc. The Board of Directors has also determined that each of the members of the Audit Committee is independent as defined in the applicable Marketplace Rules of the NASDAQ Stock Market, Inc. and Rule 10A-3 under the Securities Exchange Act of 1934. The Board of Directors has adopted a written charter for the Audit Committee, a current copy of which is located on our Internet website under the “Investor Relations” page. Our Internet website address is http://www.silabs.com. The Audit Committee reviews and assesses the adequacy of its charter on an annual basis. The Audit Committee held five meetings during fiscal 2022.

Compensation Committee. The Compensation Committee reviews and approves all compensation to be provided to our executive officers and makes recommendations to the Board of Directors regarding our compensation of directors. In addition, the Compensation Committee has authority to administer our stock incentive and stock purchase plans. The members of the Compensation Committee are Messrs. Bock and Lowe and Ms. Wyatt.

Compensation Committee, a current copy of which is located on our Internet website under the “Investor Relations” page. Our Internet website address is http://www.silabs.com. The Compensation Committee reviews and assesses the adequacy of its charter on an annual basis. The Compensation Committee held four meetings during fiscal 2022.

Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee focuses on issues related to the composition, practices and operations of the Board of Directors. In addition, the Nominating and Corporate Governance Committee has the authority to consider candidates for the Board of Directors recommended by stockholders and to determine the procedures with respect to such stockholder recommendations. The Committee also reviews issues and developments related to corporate governance, environmental and social matters and recommends associated standards to the Board. The members of the Nominating and Corporate Governance Committee are Messrs. Lowe and Sadana and Ms. Richardson. Ms. Richardson serves as Chairman of the Nominating and Corporate Governance Committee. The Board of Directors has determined that each member is independent as defined in the applicable Marketplace Rules of the NASDAQ Stock Market, Inc. The Board of Directors has adopted a written charter for the Nominating and Corporate Governance Committee, a current copy of which is available on our Internet website under the “Investor Relations” page. The Nominating and Corporate Governance Committee recommended, and the Board of Directors approved, the Corporate Governance Policy, which is also located on our Internet website under the “Investor Relations” page. Our Internet website address is http://www.silabs.com. The Nominating and Corporate Governance Committee held four meetings during fiscal 2022.

Corporate Development and Finance Committee.

The members of the Finance Committee are Messrs. Sooch, Wood and Conrad and Ms. Richardson. Mr. Wood serves as Chairman of the Finance Committee. The Finance Committee held five meetings during fiscal 2022.

Director Nomination

In evaluating potential director candidates, the Nominating and Corporate Governance Committee considers the appropriate balance of experience, skills and characteristics required of the Board of Directors and seeks to ensure that at least a majority of the directors are independent under the applicable Marketplace Rules of the NASDAQ Stock Market, Inc. The Nominating and Corporate Governance Committee selects director nominees based on their personal and professional integrity, depth and breadth of experience, ability to make independent analytical inquiries, understanding of our business, willingness to devote adequate attention and time to duties of the Board of Directors and such other criteria as is deemed relevant by the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee includes, and has any search firm that it engages include, women and minority candidates in the pool from which the Committee selects director candidates. The Company’s Corporate Governance Policy (approved by the Board of Directors) provides that the backgrounds and qualifications of the directors, considered as a group, should provide a diverse mix of experience, knowledge and skills. The Company does not have any other formal policy with respect to the diversity of our directors. The Nominating and Corporate Governance Committee considers the effectiveness of this policy and the effectiveness of the Board of Directors generally in the course of nominating directors for election. The Company’s Corporate Governance Policy provides that directors that are public company executive officers should not serve on more than two public company boards and other directors should not serve on more than four public company boards (with a grace period until the 2024 annual meeting of stockholders).

In identifying potential director candidates, the Nominating and Corporate Governance Committee considers recommendations made by current directors and officers. In addition, the Nominating and Corporate Governance Committee may engage a third-party search firm to identify and recommend potential candidates. The Nominating and Corporate Governance Committee includes, and has any search firm that it engages include, women and minority candidates in the pool from which the committee selects new director candidates. Finally, the Nominating and Corporate Governance Committee will consider candidates recommended by stockholders.

Any stockholder wishing to recommend a director candidate for consideration by the Nominating and Corporate Governance Committee must provide written notice not later than November 9, 2023 to the Corporate Secretary at our principal executive offices located at 400 West Cesar Chavez, Austin, Texas 78701. Any such notice should clearly indicate that it is a recommendation of a director candidate by a stockholder and must set forth (i) the name, age, business address and residence address of the recommended candidate, (ii) the principal occupation or employment of such recommended candidate, (iii) the class and number of shares of the corporation which are beneficially owned by such recommended candidate, (iv) a description of all understandings or arrangements between the stockholder and the recommended candidate and any other person or persons pursuant to which the recommendations are to be made by the stockholder and (v) any other information relating to such recommended candidate that is required to be disclosed in solicitations of proxies for the election of directors.

In addition, such notice must contain (i) a representation that the stockholder is a holder of record of stock of the corporation entitled to vote at such meeting, (ii) the name and address, as they appear on the corporation’s books, of the stockholder proposing such nomination, (iii) the class and number of shares of the corporation that are beneficially owned by such stockholder, (iv) any material interest of the stockholder in such recommendation and (v) any other information that is required to be provided by the stockholder pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended, in such stockholder’s capacity as proponent of a stockholder proposal. Assuming that a stockholder recommendation contains the information required above, the Nominating and Corporate Governance Committee will evaluate a candidate recommended by a stockholder by following substantially the same process, and applying substantially the same criteria, as for candidates identified through other sources.

Attendance at Annual Meetings

The Board of Directors encourages all directors to attend our annual meetings of stockholders if practicable. All of the directors in office at the time of the virtual annual meeting of stockholders held on April 21, 2022 attended such meeting.

12

Stockholder Communications with the Board of Directors

The Board of Directors maintains a process for stockholders to communicate with the Board of Directors or with individual directors. Stockholders who wish to communicate with the Board of Directors or with individual directors should direct written correspondence to our Corporate Secretary at our principal executive offices located at 400 West Cesar Chavez, Austin, Texas 78701. Any such communication must contain (i) a representation that the stockholder is a holder of record of stock of the corporation, (ii) the name and address, as they appear on the corporation’s books, of the stockholder sending such communication and (iii) the class and number of shares of the corporation that are beneficially owned by such stockholder. The Corporate Secretary will forward such communications to the Board of Directors or the specified individual director to whom the communication is directed unless such communication is deemed unduly hostile, threatening, illegal or similarly inappropriate, in which case the Corporate Secretary has the authority to discard the communication or to take appropriate legal action regarding such communication.

Code of Ethics

We have adopted a Code of Business Conduct and Ethics that applies to all officers, directors, employees and consultants. Our Code of Business Conduct and Ethics is located on our website under the “Investor Relations” page. Our website address is http://www.silabs.com.

Risk Management

Our Board of Directors oversees our management, which is responsible for the day-to-day issues of risk management. Such oversight is facilitated in large part by the Audit Committee, which receives reports from management, the internal audit team, the Chief Information Officer, the Chief Security Officer and the Company’s independent registered public accounting firm. In addition, members of management (including the Chief Executive Officer, Chief Financial Officer and Chief Legal Officer) may also report directly to the Board of Directors on significant risk management issues.

Director Compensation and Indemnification Arrangements

Our 2009 Stock Incentive Plan, as approved by our stockholders, limits to $750,000 in each calendar year, the maximum grant date fair value of awards payable in our common stock and cash compensation for all services as an independent director that may be provided to each of our independent directors. Under the 2009 Stock Incentive Plan, on the date of the 2022 annual meeting of stockholders, the Board of Directors granted each non-employee director a Restricted Stock Unit (“RSU”) award covering a number of shares of the Company’s common stock equal to $180,000 (or $235,000 for the Chairperson of the Board) divided by the average closing price of the Company’s common stock during the 30 trading days ending on the second trading day preceding the grant date; provided that any former employee of the Company must have served as a non-employee director for at least six months in order to receive such award. Accordingly, as Chairman of the Board, Mr. Sooch received a grant of 1,630 RSUs and Messrs. Bock, Lowe, Sadana, Wood and Mses. Luther, Richardson and Wyatt each received a grant of 1,249 RSUs on the date of the 2022 annual meeting of stockholders. The RSU awards require no purchase price payment and will vest on approximately the first anniversary of the date of grant.

During 2022, we paid our non-employee directors cash compensation consisting of (i) $55,000 per person per year, (ii) an additional $25,000 per year for the Chairman of the Audit Committee, (iii) an additional $9,000 per year for each Audit Committee member (excluding the Chairman), (iv) an additional $25,000 per year for the Chairman of the Compensation Committee, (v) an additional $9,000 per year for each Compensation Committee member (excluding the Chairman), (vi) an additional $10,000 per year for the Chairman of the Nominating and Corporate Governance Committee, (vii) an additional $5,000 per year for each Nominating and Corporate Governance Committee member (excluding the Chairman), (viii) an additional $20,000 per year for the Lead Director (ix) an additional $10,000 per year for the Chairman of the Finance Committee, (x) an additional $5,000 per year for each

13

Finance Committee member (excluding the Chairman) and (xi) an additional $20,000 per year for the Chairman of the Board. Payments under the cash compensation plan are generally paid in equal quarterly installments on the last day of each fiscal quarter.

Cash compensation was pro-rated if the individual served less than the full year in a position.

Our certificate of incorporation limits the personal liability of our directors for breaches by them of their fiduciary duties. Our bylaws require us to indemnify our directors to the fullest extent permitted by Delaware law. We have also entered into indemnification agreements with all of our directors and have purchased Director and Officers liability insurance.

In addition to the above compensation, we also reimburse non-employee directors for all reasonable out-of-pocket expenses incurred for attending board and committee meetings.

The following table provides summary information on compensation earned by each non-employee member of our Board of Directors in fiscal 2022.

Proposal Two: Ratification of Appointment of Independent Registered Public Accounting Firm

Our Audit Committee has appointed the firm of Ernst & Young LLP to serve as our independent registered public accounting firm for the fiscal year ending December 30, 2023. Ernst & Young LLP has audited our financial statements since our inception in 1996. A representative of Ernst & Young LLP is expected to be present at the Annual Meeting and will have an opportunity to make a statement if he or she so desires and will be available to respond to appropriate questions.

The following table presents fees for professional services rendered by Ernst & Young LLP for fiscal 2022 and 2021:

Audit Fees. Audit fees relate to services rendered in connection with the audits of the annual consolidated financial statements and internal control over financial reporting included in our Form 10-K, the quarterly reviews of financial statements included in our Form 10-Q filings, fees associated with SEC registration statements, assistance in responding to SEC comment letters, accounting consultations related to audit services and statutory audits required internationally.

Audit-Related Fees. Audit-related fees include services for assurance and other related services, such as consultations concerning financial accounting and reporting matters and due diligence related to mergers and acquisitions.

Tax Fees. Tax fees include services for tax compliance, research and technical tax advice.

All Other Fees. All other fees include the aggregate fees for products and services provided by Ernst & Young LLP that are not reported under “Audit Fees,” “Audit-Related Fees” or “Tax Fees.”

The Audit Committee is authorized by its charter to pre-approve all auditing and permitted non-audit services to be performed by our independent registered public accounting firm. The Audit Committee reviews and approves the independent registered public accounting firm’s retention to perform attest services, including the associated fees. The Audit Committee also evaluates other known potential engagements of the independent registered public accounting firm, including the scope of the proposed work and the proposed fees, and approves or rejects each service, taking into account whether the services are permissible under applicable law and the possible impact of each non-audit service on the independent registered public accounting firm’s independence from management. At subsequent meetings, the Committee will receive updates on the services actually provided by the independent registered public accounting firm, and management may present additional services for approval. The Committee has delegated to the Chairman of the Audit Committee the authority to evaluate and approve engagements on behalf of the Committee in the event that a need arises for pre-approval between Committee meetings. If the Chairman so approves any such engagements, he or she will report that approval to the full Audit Committee at its next meeting. During fiscal 2022, all such services were pre-approved in accordance with the procedures described above.

Our Audit Committee has reviewed the fees described above and believes that such fees are compatible with maintaining the independence of Ernst & Young LLP.

15

Stockholder ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm is not required by our bylaws or other applicable legal requirement. However, the appointment of Ernst & Young LLP is being submitted to the stockholders for ratification. If the stockholders fail to ratify the appointment, the Audit Committee will reconsider whether or not to retain the firm. Even if the appointment is ratified, the Audit Committee at its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be appropriate.

16

Proposal Three: Advisory Vote on Executive Compensation

The Dodd-Frank Wall Street Reform and Consumer Protection Act, enacted in July 2010, enables our stockholders to vote annually to approve, on an advisory (non-binding) basis, the compensation of our Named Executive Officers as disclosed in this Proxy Statement in accordance with the rules of the Securities and Exchange Commission.

This vote is advisory, and, therefore, not binding on the Company, the Compensation Committee, or our Board of Directors. However, our Board of Directors and our Compensation Committee value the opinions of our stockholders and to the extent there is any significant vote against the compensation of the Named Executive Officers as disclosed in this Proxy Statement, we will consider our stockholders’ concerns and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.

As described in detail under the heading “Compensation Discussion and Analysis,” our executive compensation program is designed to attract, motivate, and retain the Named Executive Officers, who are critical to our success. Under this program, the Named Executive Officers are rewarded for the achievement of strategic and operational objectives and the realization of increased stockholder value. Please read the Compensation Discussion and Analysis and the accompanying compensation tables beginning on page 24 of this Proxy Statement for additional information about our executive compensation program, including information about the compensation of the Named Executive Officers in fiscal 2022.

The Compensation Committee regularly reviews our executive compensation program to ensure that it achieves the desired goal of aligning our executive compensation structure with the interests of our stockholders and current market practices.

We are asking our stockholders to indicate their support for the compensation of the Named Executive Officers as described in this Proxy Statement. This proposal, commonly known as a “Say-on-Pay” proposal, gives our stockholders the opportunity to express their views on the compensation of the Named Executive Officers. Please note that this vote is not intended to address any specific item of compensation, but rather the overall compensation of the Named Executive Officers and the philosophy, policies and practices described in this Proxy Statement.

We will ask our stockholders to vote “FOR” the following resolution at the Annual Meeting:

“RESOLVED, that the compensation paid to the Company’s Named Executive Officers as disclosed in this Proxy Statement is hereby approved.”

17

Proposal Four: Advisory Vote on the Frequency of the Advisory Vote on Executive Compensation

The Dodd-Frank Wall Street Reform and Consumer Protection Act also enables our stockholders to indicate how frequently we should seek an advisory vote on the compensation of the Named Executive Officers, as disclosed in accordance with the rules of the Securities and Exchange Commission, such as Proposal Three above. By voting on this Proposal Four, stockholders may indicate whether they would prefer that we conduct future advisory votes on Named Executive Officer compensation once every one, two, or three years.

Our Board of Directors has determined that an advisory vote on executive compensation that occurs every year is the most appropriate alternative for the Company. Our Board of Directors considered that an annual advisory vote on executive compensation will allow our stockholders to provide us with their direct input on our compensation philosophy, policies, and practices as disclosed in the proxy statement every year. Additionally, an annual advisory vote on executive compensation is consistent with our policy of seeking input from, and engaging in discussions with, our stockholders on corporate governance matters and our executive compensation philosophy, policies and practices. We understand that our stockholders may have different views as to what is the best approach for the Company, and we look forward to hearing from our stockholders on this Proposal.

You may cast your vote on your preferred voting frequency by choosing the option of one year, two years, three years or abstain from voting in response to the resolution set forth below.

“RESOLVED, that the stockholders determine, on an advisory basis, whether the preferred frequency of an advisory vote on the executive compensation of the Company’s named executive officers should be every year, every two years or every three years.”

The option of one year, two years or three years that receives the highest number of votes cast will be the frequency selected by stockholders for the advisory vote on executive compensation. However, because this vote is advisory and not binding on the Company or our Board of Directors, our Board of Directors may decide that it is in the best interests of our stockholders and the Company to hold an advisory vote on executive compensation more or less frequently than the option approved by our stockholders.

Certain Relationships and Related Transactions, and Director Independence

Certain Relationships and Related Transactions

Our bylaws require us to indemnify our directors and executive officers to the fullest extent permitted by Delaware law. We have entered into indemnification agreements with all of our directors and executive officers and have purchased Director and Officers liability insurance. In addition, our certificate of incorporation limits the personal liability of the members of our Board of Directors for breaches by the directors of their fiduciary duties.

Policies and Procedures with Respect to Related Party Transactions

Our Audit Committee Charter requires that the members of our Audit Committee, all of whom are independent directors, review and approve all related party transactions as described in Item 404 of Regulation S-K promulgated by the SEC. We have also adopted a written policy regarding the approval of all related party transactions. Under such policy, each of our directors and executive officers must notify the Corporate Secretary (who, in turn, will provide such information to the Audit Committee) of any proposed related party transactions. To assist with the identification of potential related party transactions, we solicit information through questionnaires in connection with the appointment of new directors and executive officers and on an annual basis with respect to existing directors and executive officers. The Chairman of the Audit Committee is delegated the authority to approve or ratify any related party transactions in which the aggregate amount involved is expected to be less than $1 million per year. All other proposed related party transactions are subject to approval or ratification by the Audit Committee except for certain categories of transactions that are deemed to be pre-approved by the Audit Committee. In determining whether to approve or ratify a related party transaction, the Audit Committee and the Chairman, if applicable, will take into account, among other factors deemed appropriate, whether the related party transaction is on terms no more favorable to the counterparty than terms generally available to an unaffiliated third-party under the same or similar circumstances and the extent of the related party’s interest in the transaction.

Our Code of Business Conduct and Ethics requires our executive officers and directors to disclose any conflicts of interest, including any material transaction or relationship involving a potential conflict of interest. No executive officer may work, including as a consultant or a board member, simultaneously for us and any competitor, customer, supplier or business partner without the prior written approval of our Chief Financial Officer or legal department. Furthermore, executive officers are encouraged to avoid any direct or indirect business connections with our competitors, customers, suppliers or business partners.

Pursuant to our Corporate Governance Policy, we expect each of our directors to ensure that other existing and future commitments do not conflict with or materially interfere with their service as a director. Directors are expected to avoid any action, position or interest that conflicts with our interests, or gives the appearance of a conflict. In addition, directors should inform the Chairman of our Nominating and Corporate Governance Committee prior to joining the board of another public company to ensure that any potential conflicts, excessive time demands or other issues are carefully considered.

Director Independence

See the subsection entitled “Committees and Meetings” in the section of this Proxy Statement entitled “Proposal One: Election of Directors.”

Audit Committee Report

The following is the report of the Audit Committee with respect to the audit of the fiscal 2022 consolidated financial statements of Silicon Laboratories Inc. (the “Company”):

Management is responsible for the Company’s internal controls and the financial reporting process. The independent registered public accounting firm is responsible for performing an independent audit of the Company’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and for issuing a report thereon. Additionally, the independent registered public accounting firm is responsible for performing an independent audit of the Company’s internal control over financial reporting and for issuing a report thereon. The Committee’s responsibility is to monitor and oversee these processes.

In this context, the Committee has met and held discussions with management and the independent registered public accounting firm. Management represented to the Committee that the Company’s consolidated financial statements in the Annual Report were prepared in accordance with accounting principles generally accepted in the United States, and the Committee has reviewed and discussed the consolidated financial statements in the Annual Report with management and the independent registered public accounting firm. The Committee has discussed with the independent registered public accounting firm, Ernst & Young LLP, the required communications specified by auditing standards together with guidelines established by the Securities and Exchange Commission and the Sarbanes-Oxley Act.

The Company’s independent registered public accounting firm also provided to the Committee the written disclosures required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence. The Audit Committee reviewed non-audit services provided by its independent registered public accounting firm for the last fiscal year and determined that those services are not incompatible with maintaining the independent registered public accounting firm’s independence.

Based upon the Committee’s discussion with management and the independent registered public accounting firm and the Committee’s review of the representation of management and the reports of the independent registered public accounting firm to the Committee, the Committee recommended that the Board of Directors include the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed with the Securities and Exchange Commission.

Compensation Discussion and Analysis

This Compensation Discussion and Analysis (CD&A) provides information regarding the 2022 compensation program for our principal executive officer, principal financial officer and two other most highly compensated executive officers. We had no other executive officers during 2022. For 2022, these individuals were:

We refer to these executive officers collectively in this Proxy Statement as the “Named Executive Officers” or “NEOs.”

In this CD&A, we describe the material elements of our compensation program for the NEOs during 2022 as administered by the Compensation Committee. This analysis also provides an overview of our executive compensation philosophy, including our principal compensation policies and practices, for our NEOs. Finally, we explain how and why the Compensation Committee arrived at the specific compensation decisions for our Named Executive Officers in 2022 and discuss the key factors that the Compensation Committee considered in determining their compensation.

2022 Business Results

In our first full year as a pure-play IoT focused company, total revenue increased 42% from 2021 to $1,024 million, doubling our revenue in just two years. Our pure-play IoT strategy gained significant traction in 2022 as customers and suppliers saw the value of working with a partner focused only in the rapidly growing IoT market. Worldwide distribution revenue was 81% of 2022 revenue, with growth across all regions, particularly in Europe and the Americas. Revenue from our top ten customers was 20%, and no single customer was greater than 6% of our revenue.

We continued to see record design win activity in 2022, which increased over 50% year-on-year in expected lifetime revenue, and our total sales funnel stands at $17 billion. We had GAAP gross margins of nearly 63% in 2022, up from 59% in 2021, reflecting a favorable product and customer mix from our proprietary wireless portfolio as well as the effects of product price increases intended to input cost increases. GAAP operating income for the year increased to $119 million from 2022 due to higher revenue and gross margin, offset partially by a 14% year-on-year increase in operating expenses. Net interest income increased from 2021, primarily due to rising yields on cash, cash equivalents and short-term investments. Headcount at the end of the year was 1,964, and grew approximately 18% over 2021, due to continued hiring and expansion, particularly in our India development center.

In 2022, cash flow from operating activities was $141 million. The strong operating cash flow, in addition to the remaining cash proceeds from our 2021 divestiture allowed us to return $888 million of capital to our shareholders through stock repurchases. We ended the year with approximately $1.2 billion in cash, cash equivalents, and short-term investments. We are pleased to have successfully executed our capital deployment plan post-divestiture while maintaining substantial liquidity for prospective strategic M&A endeavors.

2022 Business Highlights

We produced record 2022 revenue despite continued supply challenges across the entire industry. Revenue was up 42% over 2021 and reflects an organic doubling of revenue over two years. We also saw record design win activity in 2022, which increased over 50% year-on-year in expected lifetime revenue, providing further validation of strategy, and, importantly, the breadth and depth of our technology portfolio.    

The strength of Silicon Labs’ product portfolio continues to drive share gain and accelerate our design win pipeline – positioning us to continue to outperform the market. In 2022, we introduced new and innovative products, including the expansion of the Series 2 SoC family:

Significant Executive Compensation Actions

Our Compensation Committee, which consists entirely of independent directors, sets the compensation of our Named Executive Officers. In 2022, the Compensation Committee took the following actions with respect to NEO compensation. As noted above, the Company produced strong business results, which positively impacted performance-based compensation elements and outcomes:

27

Significant Corporate Governance Standards

We have endeavored to maintain high standards in our executive compensation and governance practices. The following policies were in effect in 2022:

Compensation Philosophy

Our executive compensation program supports our long-term strategic and operational goals. It is intended to attract, motivate, and retain talented individuals to serve as our executive officers. The Compensation Committee designs the various components of our executive compensation program to be market competitive and support growth and profitability objectives while remaining aligned with our culture.

28

We hold our executives to high performance standards and our compensation arrangements for our CEO and other Named Executive Officers are designed to deliver competitive base pay and attractive incentive opportunities if performance is outstanding while delivering significantly lower actual compensation when performance is below our rigorous standards. To this end, a significant portion of target compensation for our executives is designed to be at risk.

Salaries are compared not only to our peer group listed below, but also to data from the Radford Technology survey. Our target for salaries, considering data from each source, is market competitive. Our annual cash incentive plan, discussed below, is based solely on achieving corporate targets. This plan targets above-market awards when the Company is performing well and places cash incentives at risk when performance targets are not achieved. See also “Annual Cash Incentive Bonus” below.

Our equity program includes time-vesting restricted stock units (RSUs), performance stock units (PSUs), and market stock units (MSUs) that are intended to incentivize achievement of high-performance standards. Our performance-based MSUs require significant levels of performance measured by our total shareholder return (or “TSR”) relative to the TSRs of a group of benchmark companies consisting of publicly traded companies included in the Philadelphia Semiconductor Index (“XSOX” or “Index”) and our peer group of companies listed under “Compensation Setting Process – Competitive Positions” below. In 2021, we transitioned away from MSUs to a performance-based PSU program, more appropriate during the period of our company’s transformation and transition to a new business model. Our PSUs also require significant levels of multi-year performance, measured by our achievement against our stated financial model and growth targets. These program design changes were made in consultation with our compensation consultant.

This approach provides a strong alignment between pay-for-performance, operational results and retention of key executive talent. The design appropriately establishes a clear focus on achieving our financial objectives. As such, our compensation program provides modest compensation when longer-term performance is below expectations. We believe that this approach optimally aligns the interests of management and our stockholders and results in the greatest emphasis on long-term stockholder value creation. For more information on the design of our equity programs and for awards granted in 2022, see “Long-term Incentives Equity Awards” below.

Prior Say On Pay Vote and Shareholder Engagement

Our prior advisory Say-on-Pay proposal regarding the compensation of our Named Executive Officers received the support of approximately 59% of the votes cast at the 2022 Annual Meeting. The Compensation Committee and the Board reviewed the result of the Say-on-Pay vote, and they recognized that it signaled shareholder concerns and a need for further engagement to better understand the perspectives of our shareholders. In connection with and following the 2022 Annual Meeting, the Company reached out to our top 20 shareholders who represented approximately 70% of the Company’s outstanding shares of common stock. We ultimately spoke with shareholders representing approximately 54% of the Company’s outstanding shares of common stock, including at least 11% of the outstanding shares that voted “against” our Say-on-Pay proposal last year. Our Chief Financial Officer led each of the meetings, and our Compensation Committee Chair or Nominating and Governance Committee Chair participated in many of these meetings. The feedback received was then shared and discussed with the Compensation Committee and the Board.

The principal concern expressed by shareholders was with our payment of cash severance to our former CEO Tyson Tuttle upon his resignation. The Compensation Committee has noted such concern and has approved a resolution that it will not provide cash severance in the future to executive officers upon a voluntary resignation (other than as may be contractually committed, such as upon a resignation for good reason).

We received comment that our CEO stock ownership guidelines could be more robust. In response, we increased our CEO stock ownership guidelines from five times to six times base salary.

29

We also received comments on our PSU measurement periods. We evaluated our PSU plan design to ensure that all metrics are multi-year measures and aligned to our long-term stated financial model and growth targets.

We believe that shareholder engagement is important, and our Compensation Committee will continue to take into account shareholder feedback, future Say-on-Pay votes and relevant market developments in order to determine whether any subsequent changes to our executive compensation program are warranted. We expect to continue our outreach efforts with respect to executive compensation in future years in order to ensure that we understand our shareholder views and concerns on each of these subjects for the consideration of our Compensation Committee and the full Board. We made the following changes to our compensation program in response to stockholder feedback:

Compensation-Setting Process

Role of Compensation Committee. The Compensation Committee is responsible for administering our executive compensation program, as well as determining and approving the compensation for our Named Executive Officers. The Compensation Committee regularly reports to our Board of Directors on its deliberations and actions.

The Compensation Committee uses a balanced approach to set the compensation of our executive officers, with each primary direct component of compensation (base salary, annual cash incentive bonus, and long-term incentive compensation) designed to play a specific role. The Compensation Committee determines the compensation of each executive officer with respect to each compensation component based, in part, on its own analysis of competitive market data and the recommendations of our CEO, both as described below. Additionally, the Compensation Committee periodically reviews whether our compensation policies and practices create any risks reasonably likely to have a material adverse impact on the Company and the steps that have or should be taken to monitor and mitigate such risks. The Compensation Committee’s 2022 review determined that the Company’s pay policies and practices do not create risks reasonably likely to have a material adverse effect on the Company.

The Compensation Committee exercises its own judgment in making its compensation decisions and may accept or reject our CEO’s recommendations. In addition, the Compensation Committee receives input from its compensation consultant and meets in executive session (without our CEO present) prior to making its final determinations regarding compensation.

Differences in compensation among our executive officers are the result of the Compensation Committee’s exercise of its judgment, following its review of our CEO’s recommendations, its analysis of competitive market data and its consideration of overall Company performance, competitive pressures, business conditions and the potential financial impact of compensation decisions, including share ownership dilution. Pay decisions are based on competitive market data from the compensation consultant and a variety of other factors, including level of performance, the vesting and value of outstanding equity awards, each individual’s tenure, prior experience, distinctive value to the Company, variances in job responsibilities relative to similarly titled officers at other

30

companies and the Compensation Committee’s determination of the appropriate mix of compensation elements (including base salary, cash incentives and equity incentives).

In determining the compensation of our CEO, the Compensation Committee consults with the other independent members of our Board of Directors, assesses our CEO’s individual performance and considers competitive market data and the other factors described above.

For our Named Executive Officers, the Committee targets market median for base salaries and targets greater than market total direct compensation (i.e. including incentive compensation) when our stringent performance targets are achieved. The factors described above provide the framework for compensation decision-making for each Named Executive Officer. No single factor is determinative in setting pay levels, nor is the impact of any factor on the determination of pay levels quantifiable.

Role of Management. In carrying out its responsibilities, the Compensation Committee works with members of our management, including our CEO. Typically, our management assists the Compensation Committee by providing information on Company performance and its perspective on compensation matters. Our CEO generally attends Compensation Committee meetings (except with respect to discussions involving his own compensation or other executive sessions of the committee).

Our CEO makes pay recommendations to the Compensation Committee regarding our executive officers’ compensation (except for his own compensation) for the Compensation Committee using the factors mentioned above and his own review of each NEO’s performance.

Our CEO conducts this assessment with the assistance of our Chief People Officer. Our CEO then makes formal recommendations to the Compensation Committee, using data from compensation firms Mercer and Radford, regarding adjustments to base salary, annual cash incentive bonus opportunities and equity awards for his team. Our CEO also recommends performance measures and related target levels for annual cash incentive bonuses and equity awards for senior management.

The Compensation Committee solicits and reviews our CEO’s recommendations and proposals on compensation-related matters. They consider these recommendations, among other factors, as they make compensation decisions for our executive officers.

Role of Compensation Consultant. The Compensation Committee is authorized to retain the services of compensation consultants and other advisors from time to time, as it sees fit, in connection with the administration of our executive compensation programs.

The Compensation Committee retained Mercer US LLC, (“Mercer”), a compensation consulting firm providing executive compensation advisory services, to provide competitive market data and analysis regarding material elements of compensation, including base salary, cash incentives and equity incentives. Mercer served at the discretion of the Compensation Committee, and received $212,794 for these services. Mercer did not provide any other services to the Company in 2022.

With the approval of the Compensation Committee, Mercer provided our CEO and our Chief People Officer with market data regarding compensation for our executive officers so that our CEO’s compensation recommendations to the Compensation Committee are consistent with our compensation philosophy.

Competitive Positioning. The Compensation Committee believes it is in the best interests of our stockholders to ensure that our executive compensation is competitive with that of other companies of similar size and complexity. In late 2021, the Compensation Committee directed Mercer to use data gathered from the 2021 Radford High-Technology Executive Compensation Survey and publicly-available information from the following companies to

31

identify and analyze the competitive market for 2022 executive compensation. Criteria for peer group selection included industry, revenue size, market capitalization, and business characteristics. The Compensation Committee selected the following companies as a compensation peer group in consultation with Mercer:

Compensation Elements

The primary components of our executive compensation program are base salary, annual cash incentive bonus and equity awards. The Compensation Committee uses its discretion and does not use a prescribed formula for allocating compensation between annual and long-term compensation, between cash and non-cash compensation, or among different forms of non-cash compensation.

Approximately 90% of our CEO’s pay mix and on average approximately 82% of our other NEOs’ pay mix is tied to Company performance, including stock price performance (“at-risk”):

Base Salary. The 2021 and 2022 base salaries and percentage increase are set forth in the following table:

32

Annual Cash Incentive Bonus. Each year, the Compensation Committee adopts a bonus plan (the “Bonus Plan”) to reward exceptional performance and align the incentives of our Named Executive Officers with our short-term operating plan and long-term strategic objectives and the interests of our stockholders. The Compensation Committee approves the design, structure, and performance objectives, as well as each objective’s relative weighting, under the Bonus Plan. The Compensation Committee designs the Bonus Plan to pay each Named Executive Officer up to 150% of the NEO’s target annual cash incentive bonus opportunity for outstanding performance. Consistent with our “pay-for-performance” philosophy, however, no payment is guaranteed if the minimum established performance objectives under the Bonus Plan are not achieved.

For 2022, consistent with our business strategy, the Compensation Committee established adjusted revenue and adjusted non-GAAP operating income as a percentage of adjusted revenue as the principal corporate financial metrics. For this purpose, “adjusted revenue” and “adjusted non-GAAP operating income” mean revenue and operating income as determined under generally accepted accounting principles (GAAP) modified for stock compensation expense, intangible asset amortization, acquisition-related items and restructuring charges. These adjusted measures more clearly highlight the results of core ongoing operations. For purposes of cash incentive bonuses, the Compensation Committee reserves the authority to determine whether to exclude any item when making adjustments from the corresponding GAAP metric.

For 2022, the Compensation Committee is continuing to include diversity, equity and inclusion (DEI) metrics as a component of bonus compensation.

For each of the applicable bonus metrics, the percentage payout was determined using a sliding scale based on actual performance, with no minimum payout and a maximum payout of 150% of the executive’s target annual cash incentive bonus opportunity for above-target performance. The financial components of the plan allowed for 100% payout at 100% of plan target. For the adjusted revenue component, there was a decreasing scale to 10% at 90% of plan target, no payment below 90% of target and a maximum payout of 150% at 110% of target. For the adjusted non-GAAP operating income components, there was a decreasing scale to 10% at 80% of plan target, no payment below 80% of target and a maximum payout of 150% at 120% of target. The DEI components of the plan were based on a set of challenging qualitative and quantitative goals representing core objectives of our DEI strategy. If three of five goals were achieved, the plan allowed for 80% payout. If four of five goals were achieved, the plan allowed for 100% payout. If all five goals were achieved, the plan allowed for 150% payout.

Our Board of Directors and the Compensation Committee may exercise discretion either to make payments absent attainment of the relevant performance metric target levels or to reduce or increase the size of any award payment. Neither the Board of Directors nor the Compensation Committee exercised such discretion in 2022.

For all of our Named Executive Officers in 2022, the incentive bonus performance metrics, targets, achievements, and the relative weighting of the metrics were as follows:

For all of our Named Executive Officers, the adjusted revenue component of bonus paid out at 133% of component target, the adjusted non-GAAP operating income component paid out at 150% of component target, and the DEI component paid out at 100% of component target. This resulted in a total payout of 137% of target bonus for the year for each Named Executive Officer.

Appendix I provides a reconciliation of GAAP and non-GAAP executive compensation financial measures.

33

The resulting payments to the Named Executive Officers were as follows:

The cash incentive bonuses paid to the Named Executive Officers during 2022 are set forth in the Summary Compensation Table below under the heading “Non-Equity Incentive Plan Compensation.”

Long-Term Incentive Equity Awards. The Compensation Committee uses long-term incentive compensation, typically in the form of equity awards, to retain our Named Executive Officers, to align their interests with the interests of our stockholders and to provide incentives that we believe encourage behaviors that will maximize stockholder value. For 2022, the Compensation Committee used a mix of PSUs and RSUs.

PSU Awards Granted in 2021 and 2022

In 2021, we replaced our performance-based MSU program with a performance-based PSU program that we believe is more appropriate during the period of our company transformation and transition to a new business model. PSUs allow us to directly tie executive compensation to specific company financial targets that are critical to the long-term success of our pure-play IoT model. The PSU program measures performance achievement against our multi-year growth targets and financial plan.

We continued to offer PSU awards in 2022. For each PSU award, a payment in shares of our common stock relative to the target number of units may be earned upon the Company achieving goals based on a three-year revenue compound annual growth rate (CAGR) and corresponding three year non-GAAP operating income margin (OI). The CAGR metric is measured at the end of Year 3 and weighted at 50%. The OI metric is also a long-term metric, with two multi-year measurement points. The first measurement is made at the end of Year 2, evaluating a two-year period. The second and final measurement is made at the end of Year 3, evaluating a cumulative three-year period. Each of these OI measurements is weighted at 25%. Award payments may range from 0% up to 200% of the target number of units and are scaled linearly against a base revenue or non-GAAP operating income margin percentage for each measurement, all tracking to our stated financial model.

The PSU Awards will be earned based upon the level of achievement of the following multi-year performance criteria:

34

RSU Awards Granted in 2022

The RSU awards granted in 2022 provide a retention incentive and align the interests of our executive officers with those of our stockholders. These RSUs generally vest in three annual installments on each anniversary of the date of grant.

The Named Executive Officers were granted the following PSU and RSU awards during 2022:

MSU Awards Granted in 2020

In 2020, we granted MSU awards that compare our TSR against the TSRs of a group of benchmark companies that included the publicly traded companies in the XSOX and our named peer group of companies for the applicable year in which the MSU awards were granted. For each of these MSU awards, a payment in shares of our common stock relative to the target number of units may be earned if our relative TSR percentile rank over a performance measurement period of three years equals or exceeds the 50th percentile. Our relative TSR percentile rank is determined by ranking the group of benchmark companies (including us) from the highest to the lowest according to each company’s respective TSR for the performance period, then calculating the TSR percentile ranking of us relative to other companies in the group of benchmark companies. If our relative TSR percentile rank is less than the 25^th percentile, no payout is earned. If our relative TSR percentile rank, is greater than the 25^th percentile, award payments may range from 50% up to 200% of target scaled to the relative TSR percentile rank, as shown in below.

For the MSU awards granted in 2020, the SLAB TSR achieved was 23.19% and the relative TSR percentile rank was in the 26^th percentile and therefore, a 52% payout was earned.

Compensation Arrangements Upon Termination of Employment or a Change in Control

The equity awards granted to our Named Executive Officers under the Company’s 2009 Stock Incentive Plan, as amended and restated on April 22, 2021, and the CEO Severance Agreement and the Executive Severance Agreements approved by the Board in May 2021 provide for the following potential payments and benefits upon a Change in Control Termination (as defined in the agreements): (a) 100% of annual base salary (200% in the case of the CEO), (b) 100% of target variable compensation for a full fiscal year (200% in the case of the CEO), (c) any actual earned bonus, commission or other short term cash incentive compensation for the fiscal year preceding the Change in Control Termination to the extent such amount has not already been paid, (d) a pro-rated portion of target variable compensation for the full fiscal year in which the Change in Control Termination occurs, (e) stock options, restricted stock, and restricted stock units shall become fully vested, (f) market stock units and performance stock units shall be vested at the greater of actual performance or 100% of the target value, and (g) a lump sum equal to the pre-tax cost of 12 months of continued COBRA coverage (24 months in the case of the CEO). In addition, the Executive Severance Agreements provide certain specified severance benefits to the Named Executive Officers upon a Non-CIC Termination (as defined in the agreements). The terms and conditions of these change in control provisions are provided at a level that the Compensation Committee believes to be comparable to those of companies of similar size in our industry sector. Detailed information concerning the CEO Severance Agreement and the Executive Severance Agreements and the treatment of equity awards under the Company’s 2009 Stock Incentive Plan in the event of a change in control, including the events that trigger benefits and the severance benefits provided upon the occurrence of such events, is discussed below under the heading “Potential Payments Upon Termination or Change in Control.” We have provided for this treatment based on our belief that such treatment ensures that the executive officers remain focused on their responsibilities in the event of a potential transaction that will result in a significant benefit to our stockholders.

Welfare, Retirement, and Other Benefits

Welfare Benefits. The Company maintains an array of benefit programs to meet the health care and welfare needs of our employees including medical healthcare and prescription drug coverage, dental and vision programs, medical and dependent care flexible spending accounts, short-term disability insurance, long-term disability insurance, accidental death and dismemberment insurance, and group life insurance, as well as customary vacation, paid holiday, leave of absence and other similar policies. Our executive officers, including the Named Executive Officers, participate in these benefit programs on the same general terms as all of our salaried employees.

Retirement Benefits. The Company has established a tax-qualified Section 401(k) retirement savings plan for our employees. Our executive officers, including the Named Executive Officers, are eligible to participate in this plan on the same general terms available to all of our full-time employees. Currently, plan participants are provided with matching contributions that are subject to time-based vesting conditions. It is intended that this plan qualify under Section 401(a) of the Internal Revenue Code so that contributions by participants to the plan, and income earned on plan contributions, are not taxable to participants until withdrawn from the plan. Our executive officers, including the Named Executive Officers, do not receive any retirement benefits beyond those generally available to our full-time employees.

Perquisites and Other Personal Benefits. In addition to the general welfare benefits described above, the Compensation Committee has determined that we provide our executive officers, including the Named Executive Officers, with an annual physical examination beyond the benefit provided under our standard health care plans.

The Compensation Committee does not view perquisites or other personal benefits as a significant component of our executive compensation program and, except as described in the preceding paragraph, did not provide any perquisites or other personal benefits to our executive officers during 2022.

Income Tax and Accounting Considerations

Deductibility of Executive Compensation. Section 162(m) of the Internal Revenue Code, as amended by the Tax Cuts and Jobs Act of 2017 (the TCJA), effective for taxable years beginning on or after January 1, 2018, generally disallows a deduction for federal income tax purposes to any publicly traded corporation of remuneration in excess of $1 million paid in any taxable year to its covered employees, consisting of the principal executive officer, principal financial officer and the three other most highly-compensated executive officers for the taxable year. Further, any executive officer who was a covered employee for any taxable year beginning after December 31, 2016 will continue to be treated as a covered employee in all future years. Prior to the amendment, qualifying “performance-based compensation” was not subject to the deduction limitation if specified requirements were met. Under the TCJA, the performance-based compensation exception has been repealed. The prior Section 162(m) provisions will, however, continue to apply to remuneration paid pursuant to binding written contracts in effect on November 2, 2017 and that are not materially modified after that date.

The Compensation Committee believes that its primary responsibility is to provide a compensation program to meet our stated business objectives, and accordingly the Company reserves the right to pay compensation that is not tax-deductible if it determines that such a payment is in the best interests of the Company and our stockholders.

Accounting Treatment of Executive Compensation. The Company follows Financial Accounting Standards Board Accounting Standards Codification Topic 718 (“ASC Topic 718”) in accounting for our stock-based awards. ASC Topic 718 requires companies to measure the compensation cost for all stock-based options and awards to employees (including our executive officers) and directors based on the “fair value” on the date of grant. This calculation is performed for accounting purposes and reported in the compensation tables below, even though our executive officers may never realize any value from their awards. ASC Topic 718 also requires companies to recognize the fair value of their stock-based options and awards in their income statements over the period that an executive officer is required to render service in exchange for his or her grant.

Compensation Committee Report on Executive Compensation

We, the Compensation Committee of the Board of Directors, have reviewed and discussed the Compensation Discussion and Analysis within the Executive Compensation section of this Proxy Statement with the management of the Company. Based on such review and discussion, we are of the opinion that the executive compensation policies and plans provide appropriate compensation to properly align Silicon Labs’ performance and the interests of its stockholders through the use of competitive and equitable executive compensation in a balanced and reasonable manner, for both the short- and long-term. Accordingly, we have recommended to the Board of Directors that the Compensation Discussion and Analysis be included as part of this Proxy filing.
