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.

Recommendation of the Board of Directors

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 29, 2018.30, 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 20172022 and 2016:2021:

Audit Fees. Audit fees relate to services rendered in connection with the audits of the annual consolidated financial statements and attestation of management’s report on internal controlscontrol over financial reporting included in our Form10-K, the quarterly reviews of financial statements included in our Form10-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 topre-approve all auditing and permittednon-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 eachnon-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 forpre-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 2017,2022, all such services werepre-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

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 2124 of this Proxy Statement for additional information about our executive compensation program, including information about the compensation of the Named Executive Officers in 2017.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.”

Recommendation of the Board of Directors

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.

18

Other Matters

We know of no other matters that will be presented for consideration at the Annual Meeting. If any other matters properly come before the Annual Meeting, it is the intention of the persons named in the enclosed form of Proxy to vote the shares they represent as the Board of Directors may recommend. Discretionary authority with respect to such other matters is granted by the execution of the enclosed Proxy.

19

Ownership of Securities

The following table sets forth certain information known to us with respect to the beneficial ownership of our common stock as of January 31, 2018February 15, 2023 by (i) all persons who were beneficial owners of five percent or more of our common stock, (ii) each director and nominee for director, (iii) the named executive officers named in the Summary Compensation Table of the Executive Compensation section of this Proxy Statement and (iv) all then current directors and executive officers as a group. Unless otherwise indicated, each of the stockholders has sole voting and investment power with respect to the shares beneficially owned, subject to community property laws, where applicable.

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 directors’Director and officers’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.

Our Chairman of the Board, Mr. Sooch, is Chief Executive Officer, as well as a stockholder, of Ketra, Inc., a private company in the field of solid state lighting. In fiscal 2017, we sold approximately $0.3 million of products to Ketra in the ordinary course of business.

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 RegulationS-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 bepre-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.

Significant Corporate Governance Standards

We have endeavored to maintain high standards in our executive compensation and governance practices. The following policies remainedwere in effect in 2017:2022:

We hold our executives to high performance standards and our compensation plansarrangements 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 including financial targets with MBO targets for two of our Named Executive Officers.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 BonusBonus” below.

In ourOur equity program in additionincludes time-vesting restricted stock units (RSUs), performance stock units (PSUs), and market stock units (MSUs) that are intended to time-based RSUs, we use two formsincentivize achievement of performance shares,high-performance standards. Our performance-based MSUs and PSUs, to maintain high performance standards in our long-term incentive plan. Our use of MSUs began in 2012 and has consistently been part of our long-term incentive strategy. We require significant levels of performance in terms of Total Shareholder Returnmeasured 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”) forand our peer group of companies listed under “Compensation Setting Process – Competitive Positions” below. In 2021, we transitioned away from MSUs to be earned at target levels.

In additiona performance-based PSU program, more appropriate during the period of our company’s transformation and transition to MSUs, we usea new business model. Our PSUs to incentivizealso require significant levels of multi-year performance, measured by our achievement against our stated financial model and reward operational focus on revenue growth. With a target at 10% revenue growth year-over-year, PSUs provide zero reward for 5% or less revenue growth and, conversely, pays 200% of target upon achieving 15% revenue growth. The revenue growth factor is prorated for revenue growth between 5% and 15% (i.e. if revenue growth is 9%, the revenue growth factor of 80% is applied to determine the PSU result). We believe these performance awards appropriately focustargets. These program design changes were made in consultation with our executives on operational activities that drive sustained performance and growth.compensation consultant.

This equity approach provides a strong alignment betweenpay-for-performance, operational results and retention of key executive talent. The design appropriately establishes a clear focus on TSR and year-over-year revenue growth.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 2017,2022, 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.
