Matters to be Considered at Annual Meeting

Silicon Laboratories Inc. Proxy Statement

Annual Meeting of Stockholders to be held on April 18, 2024

General

The enclosed Proxy is solicited on behalf of the Board of Directors of Silicon Laboratories Inc., a Delaware corporation, for use at the Annual Meeting of Stockholders to be held on April 18, 2024 at 9:00 a.m. Central Time and which will be conducted virtually via a live webcast atwww.proxydocs.com/SLAB, or at any adjournment thereof. On or about March 6, 2024 we mailed to our stockholders a notice containing instructions on how to vote and how to access our 2024 Proxy Statement and 2023 Annual Report.

Voting

The specific proposals to be considered and acted upon at the Annual Meeting are summarized in the accompanying notice and are described in more detail in this Proxy Statement. On February 23, 2024, the record date for determination of stockholders entitled to notice of and to vote at the Annual Meeting, 31,921,227 shares of our common stock were outstanding and no shares of our preferred stock were outstanding. Each stockholder is entitled to one vote for each share of common stock held by such stockholder on February 23, 2024. The presence, or representation by proxy, of the holders of a majority of our shares entitled to vote is necessary to constitute a quorum at the Annual Meeting or at any adjournment thereof. Stockholders may not cumulate votes in the election of directors. The affirmative vote of a majority of the votes cast (including votes cast by proxy) at the Annual Meeting with respect to each director’s election is necessary for the election of such director. The affirmative vote of a majority of our shares present or represented by proxy at the Annual Meeting and entitled to vote will be required to approve Proposals Two and Three. All votes will be tabulated by the inspector of elections appointed for the meeting, who will separately tabulate affirmative and negative votes, abstentions and brokernon-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 brokernon-votes will be counted as present for purposes of determining a quorum for the transaction of business. Abstentions will have no effect on the election of directors but will be counted as shares “entitled to vote” and therefore will have the same effect as a vote against Proposals Two and Three. Brokernon-votes will not be counted for purposes of determining whether each proposal has been approved.

Proxies

If the enclosed form of Proxy is properly signed and returned or you properly follow the instructions for telephone or Internet voting, the shares represented thereby will be voted at the Annual Meeting in accordance with the instructions specified thereon. If the Proxy does not otherwise specify how the shares represented thereby are to be voted, the Proxy will be voted (i) FOR the election of the directors proposed by the Board of Directors, (ii) FOR the approval of the selection of Ernst & Young LLP as our independent registered public accounting firm and (iii) FOR the approval of an advisory resolution to approve executive compensation. You may revoke or change your Proxy at any time before the Annual Meeting by filing either a notice of revocation or another signed Proxy with a later date with our Corporate Secretary at our principal executive offices at 400 West Cesar Chavez, Austin, Texas 78701. You may also revoke your Proxy by attending the Annual Meeting and voting during the meeting.

Solicitation

We will bear the entire cost of solicitation, including the preparation, assembly, printing and mailing of this Proxy Statement, the Proxy and any additional solicitation materials furnished to the stockholders. Copies of solicitation materials will be furnished to brokerage houses, fiduciaries and custodians holding in their names shares that are

beneficially owned by others so that they may forward this solicitation material to such beneficial owners. In addition, we may reimburse such persons for their costs in forwarding the solicitation materials to such beneficial owners. The original solicitation of Proxies by mail and the Internet may be supplemented by a solicitation by telephone or other means by directors, officers, or employees. No additional compensation will be paid to these individuals for any such services. Except as described above, we do not presently intend to solicit Proxies other than by mail and the Internet.

These proposals must comply with applicable Delaware law, the rules and regulations promulgated by the Securities and Exchange Commission (“SEC”) and the procedures set forth in our bylaws. Pursuant to our bylaws, stockholder proposals received after November 6, 2024, will be considered untimely. In addition to satisfying advance notice requirements under our bylaws, to comply with the universal proxy rules under the Exchange Act, stockholders who intend to solicit proxies in support of director nominees other than those nominees nominated by the Company must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than February 17, 2025, which is 60 days prior to the anniversary date of the 2024 annual meeting of stockholders.
