PROXY STATEMENT

FOR THE 2026 ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD WEDNESDAY, APRIL 29, 2026

GENERAL INFORMATION ABOUT SELECTIVE’S ANNUAL MEETING

WHEN AND WHERE IS THE ANNUAL MEETING?

The 2026 Annual Meeting of Stockholders (the “Annual Meeting”) of Selective Insurance Group, Inc. (“Selective,” “Company,” “we,” “us,” and “our”) will be held virtually on Wednesday, April 29, 2026, at 8:30 AM Eastern Time exclusively via live audiocast. The Annual Meeting will not have a physical location, and you will not be able to attend the meeting in person. You can participate, vote, and submit questions online during the Annual Meeting by visiting http://www.virtualshareholdermeeting.com/SIGI2026 and entering the 16-digit control number on your proxy card. See below for additional information regarding the virtual meeting format.

WHEN IS THIS PROXY STATEMENT BEING MAILED OR RELEASED TO STOCKHOLDERS?

This Proxy Statement and proxy card are first being mailed or given to Selective stockholders on or about March 26, 2026.

WHO IS ENTITLED TO VOTE AT THE ANNUAL MEETING?

Anyone who owned Selective common stock as of the close of business on March 6, 2026 (the “Record Date”) is entitled to one vote per share owned. There were 59,866,404 shares of Selective common stock outstanding at the close of business on the Record Date.

WHO IS SOLICITING MY PROXY TO VOTE MY SHARES AND WHEN?

Selective’s Board of Directors (the “Board”) is soliciting your proxy, meaning your authorization for our named proxies, Thomas A. McCarthy and Julie Parsons, to vote your shares. Unless you revoke your proxy, it will be effective for the Annual Meeting and its adjournments, postponements, or continuations, if any.

WHAT IS THE COST OF SOLICITING PROXIES AND WHO IS PAYING FOR THE COST?

Selective is bearing the entire cost of soliciting proxies. Proxies will be solicited principally by mail and email. They also may be solicited in person, in writing, by telephone, text message, email, or otherwise by directors or employees, including officers of Selective or a Selective subsidiary, who will receive no additional compensation for these efforts. Selective has engaged Innisfree M&A Incorporated, a proxy solicitation firm (“Innisfree”), to assist in soliciting proxies and distributing proxy materials. Innisfree will provide such services for an estimated fee of approximately $17,500, plus expenses. Selective will reimburse banks, brokerage firms, and other custodians, nominees, and fiduciaries for reasonable expenses they incur in sending proxy materials to their customers or principals who are the beneficial owners of shares of Selective common stock.

WHAT ARE THE REQUIREMENTS FOR BUSINESS TO BE CONDUCTED AT THE ANNUAL MEETING?

For business to be conducted at the Annual Meeting, owners of 29,933,203 shares of Selective common stock (a majority of the issued and outstanding shares entitled to vote), constituting a quorum, must be in attendance by virtual participation or represented by proxy. Our common stock is our only class of voting securities.

HOW DO STOCKHOLDERS ATTEND THE VIRTUAL ANNUAL MEETING?

The Annual Meeting will be held exclusively via live audiocast, allowing meeting attendance from anywhere in the world. We are pleased to use virtual stockholder meeting technology to provide ready access and cost savings for Selective and its stockholders.

To be admitted to the Annual Meeting at http://www.virtualshareholdermeeting.com/SIGI2026, you must enter the
16-digit control number on the proxy card you received. You can vote online, submit your questions, and examine Selective’s stockholder list by following the instructions provided on the meeting website during the Annual Meeting.

Page 2

The meeting will begin promptly at 8:30 AM Eastern Time on April 29, 2026. Online access will start at 8:15 AM Eastern Time. We encourage you to access the meeting website before the start time to ensure sufficient time to complete the check-in procedures. If you are not a stockholder, you may still access the meeting website as a guest, but you will not be able to vote, ask questions, or view the stockholder list.

The virtual meeting platform is fully supported across internet browsers (Microsoft Edge, Mozilla Firefox, Google Chrome, and Safari) and devices (desktops, laptops, tablets, and mobile phones) running the most updated version of applicable software and plugins. You will be able to test the system before the Annual Meeting starts. If you encounter any technical difficulties logging onto http://www.virtualshareholdermeeting.com/SIGI2026 or during the Annual Meeting, a toll-free number and international number will be available on the meeting website to help you. Technicians will be ready to assist you with any technical difficulties from 8:15 AM Eastern Time through the Annual Meeting’s conclusion.

HOW DO STOCKHOLDERS ASK QUESTIONS AT THE ANNUAL MEETING?

The Annual Meeting will include a question-and-answer session. We will answer questions relevant to Selective and meeting matters submitted following the meeting rules posted on the meeting website (http://www.virtualshareholdermeeting.com/SIGI2026). Stockholders can submit written questions via the Internet at any time during the Annual Meeting by following the instructions that will be available on the meeting website. Stockholders must have their control number to ask a question. To accommodate questions from as many stockholders as possible, each stockholder is limited to two questions. Substantially similar questions will be grouped and answered once to avoid repetition and allow more time for other questions. To ensure the meeting is conducted fairly for all stockholders, the Chairperson of the Annual Meeting may exercise discretion in recognizing stockholders wishing to participate, the order in which questions are addressed, and the amount of time devoted to any one question. By attending the Annual Meeting virtually, stockholders agree to abide by the agenda and procedures for the Annual Meeting.

PROPOSALS FOR STOCKHOLDER VOTE AND APPROVAL REQUIREMENTS

Management is presenting three proposals for a stockholder vote.

PROPOSAL 1. ELECTION OF DIRECTORS

DIRECTORS ARE SUBJECT TO ANNUAL ELECTION BY THE STOCKHOLDERS. THE BOARD RECOMMENDS THAT YOU VOTE “FOR” EACH OF THE FOLLOWING 12 DIRECTOR NOMINEES FOR A TERM OF ONE YEAR:

AINAR D. AIJALA, JR.	STEPHEN C. MILLS
LISA ROJAS BACUS	H. ELIZABETH MITCHELL
TERRENCE W. CAVANAUGH	CYNTHIA S. NICHOLSON
ROBERT KELLY DOHERTY	JULIE PARSONS
JOHN J. MARCHIONI	KATE E. R. SAMPSON
THOMAS A. MCCARTHY	JOHN S. SCHEID

You can find information about the director nominees, the Board, its committees, and other related matters in the section entitled, “Information about Proposal 1” of this Proxy Statement.

New Jersey law and Selective’s By-Laws govern the vote on Proposal 1, on which you may:

◾

Vote “FOR” all of the director nominees;

◾

Vote “AGAINST” all of the director nominees;

◾

Vote “FOR” or “AGAINST” specific director nominees; or

◾

Abstain from voting for all or specific director nominees.

Page 3

Under our By-Laws and assuming a quorum is present, a director nominee in an uncontested election must be elected by a majority of votes cast at the Annual Meeting. A majority exists when the number of votes cast “For” a director nominee exceeds the number of votes cast “Against” the director nominee. A director nominee who fails to receive a majority of votes cast in an uncontested election is required to tender their resignation from the Board within five days following the certification of the election results. In that event, (i) the Corporate Governance and Nominating Committee must recommend to the Board whether it should accept the resignation, and (ii) the Board must decide whether to accept the resignation and disclose its decision-making process.

Stockholders may not cumulate their votes. Abstentions and broker non-votes will not be taken into account in determining the outcome of the vote.

PROPOSAL 2. APPROVAL, ON AN ADVISORY BASIS, OF THE 2025 COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL, ON AN ADVISORY BASIS, OF THE 2025 COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS DISCLOSED IN THIS PROXY STATEMENT.

You can find information about the compensation of our named executive officers in the section entitled, “Executive Compensation” and about Proposal 2 in the section entitled, “Information about Proposal 2” of this Proxy Statement.

New Jersey law and Selective’s By-Laws govern the vote on Proposal 2, on which you may:

◾

Vote “FOR” Proposal 2;

◾

Vote “AGAINST” Proposal 2; or

◾

Abstain from voting on Proposal 2.

Assuming a quorum is present, Proposal 2 will pass if approved by an affirmative vote of a majority of the votes cast at the Annual Meeting. Abstentions and broker non-votes will not be taken into account in determining the outcome of the vote.

PROPOSAL 3. RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF KPMG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2026.

You can find information about Selective’s relationship with KPMG LLP in the section entitled, “Information about Proposal 3” of this Proxy Statement. New Jersey law and Selective’s By-Laws govern the vote on Proposal 3, on which you may:

◾

Vote “FOR” Proposal 3;

◾

Vote “AGAINST” Proposal 3; or

◾

Abstain from voting on Proposal 3.

Assuming a quorum is present, Proposal 3 will pass if it receives an affirmative vote of a majority of the votes cast at the Annual Meeting. Abstentions will not be taken into account in determining the outcome of the vote. Proposal 3 is considered a “routine” matter on which brokers may cast a vote.

OTHER MATTERS TO COME BEFORE THE ANNUAL MEETING

The Board is unaware of any other business to be presented for a vote at the Annual Meeting. If any other matters are properly presented for a vote, the individuals named as proxies will have discretionary authority to vote on such matters using their best judgment to the extent permitted by applicable laws, rules, and regulations.

The Chairperson of the Annual Meeting may refuse to allow the presentation of a proposal or nominee for the Board if the proposal or nominee is not properly submitted. The requirements for submitting proposals and director nominations for the Annual Meeting are detailed in Selective’s By-Laws.

VOTING AND PROXY PROCEDURE

HOW DO I VOTE?

If you are the record holder of your shares, you can vote in four ways:

BY MAIL (PROXY CARD MUST BE RECEIVED BEFORE THE ANNUAL MEETING):

◾

Mark your voting instructions on your proxy card;

◾

Sign your name exactly as it appears on your proxy card;

◾

Date your proxy card; and

◾

Mail your proxy card to us in the provided postage-paid envelope.

Timing is important, so please mail your proxy card promptly. We must receive it before the commencement of the Annual Meeting. If you do not give voting instructions on your signed and mailed proxy card, the named proxies will vote your shares “FOR” each of the director nominees in Proposal 1 and “FOR” each of Proposals 2 and 3.

BY TELEPHONE (MAY BE DONE AT ANY TIME UNTIL TUESDAY, APRIL 28, 2026 AT 11:59 PM EASTERN TIME):

◾

Call the toll-free number on your proxy card; and

◾

Follow the instructions on your proxy card and the voice prompts.

IF YOU VOTE BY TELEPHONE, YOU DO NOT NEED TO RETURN YOUR PROXY CARD.

BY INTERNET (MAY BE DONE AT ANY TIME UNTIL TUESDAY, APRIL 28, 2026 AT 11:59 PM EASTERN TIME):

◾

Go to the website listed on your proxy card; and

◾

Follow the instructions on your proxy card and the website.

IF YOU VOTE BY INTERNET, YOU DO NOT NEED TO RETURN YOUR PROXY CARD.

BY VIRTUAL PARTICIPATION (MAY ONLY BE DONE ON WEDNESDAY, APRIL 29, 2026 DURING THE ANNUAL MEETING):

◾

Virtually attend the Annual Meeting and vote online during the audiocast.

If your shares are held in our 401(k) plan or employee stock purchase plan, you can vote in any of the above four ways; provided, however, if you choose to vote by telephone (option 2) or by internet (option 3), you must do so before 11:59 PM Eastern Time on SUNDAY, April 26, 2026.

HOW DO I REVOKE MY PROXY OR CHANGE MY VOTING INSTRUCTIONS?

You may revoke your proxy at any time before the proxy is exercised at the Annual Meeting by:

◾

Submitting a new vote by telephone, via the Internet, or by returning a properly executed new proxy card bearing a later date. Any subsequent timely and valid vote by any method will change your prior vote. For example, if you voted by telephone, a subsequent Internet vote will change your vote. The vote counted will be the last vote received before 11:59 PM Eastern Time on Tuesday, April 28, 2026 (if you are the record holder of your shares) or 11:59 PM Eastern Time on Sunday, April 26, 2026 (if your shares are held in our 401(k) plan or employee stock purchase plan) – unless you change your vote by virtually attending the Annual Meeting and voting online during the Annual Meeting;

Page 5

◾

Writing to Selective’s Corporate Secretary, Robyn P. Turner, at 40 Wantage Avenue, Branchville, New Jersey 07890 (such revocation must be received before commencement of the Annual Meeting); and

◾

Virtually attending the Annual Meeting and voting online during the audiocast.

HOW WILL PROXIES BE VOTED IF I GIVE MY AUTHORIZATION?

If you (i) properly execute your proxy card and return it to Selective, or (ii) submit your proxy by telephone or via the Internet and do not subsequently revoke your proxy, your shares of common stock will be voted at the Annual Meeting according to your instructions. In the absence of voting instructions, the named proxies will vote your shares “FOR” each of the director nominees in Proposal 1 and “FOR” each of Proposals 2 and 3. If other matters properly come before the Annual Meeting, the named proxies will vote on such matters using their best judgment to the extent permitted by applicable laws, rules, and regulations.

WHAT IF MY SHARES ARE NOT REGISTERED IN MY NAME?

If the Selective stock you own is held in the name of a bank, broker, or other nominee (commonly referred to as holding shares in “street name”), your bank, broker, or other nominee should have provided you access to these proxy materials by mail or e-mail with information on how to submit your voting instructions. If you do not provide voting instructions, the broker, bank, or other holder of record cannot vote your shares on “non-routine” matters but can vote your shares on “routine” matters. “Broker non-votes” occur when a beneficial owner of shares held in street name fails to provide instructions to the broker, bank, or other nominee as to how to vote on matters deemed “non-routine.” We believe the election of directors (Proposal 1) and the advisory (non-binding) vote on the 2025 compensation of Selective’s named executive officers (Proposal 2) are “non-routine” matters, and brokers, banks, or other nominees cannot vote your shares on such proposals if you have not given voting instructions. In these cases, the broker, bank, or other nominee can register your shares as being present at the Annual Meeting for purposes of determining the presence of a quorum but will not be able to vote on those matters for which specific authorization is required under the New York Stock Exchange (“NYSE”) rules that apply to brokers.

HOW WILL VOTES, ABSTENTIONS, AND BROKER NON-VOTES BE COUNTED?

The inspector of election appointed for the Annual Meeting by the Board will separately tabulate affirmative and negative votes, abstentions, and broker non-votes. Shares represented by proxies that reflect abstentions and broker non-votes are counted to determine whether there is a quorum.

The below chart summarizes the required voting standard for each proposal and the impacts of abstentions and broker non-votes.

	Proposal	Voting Approval Standard	Effect of Abstention⁽¹⁾	Effect of Broker Non-Vote⁽²⁾
1.	Election of Directors	A nominee for director shall be elected to the Board if the votes cast for such nominee’s election exceed the votes cast against such nominee’s election⁽³⁾	No effect	No effect
2.	Approval, on an Advisory Basis, of the 2025 Compensation of our Named Executive Officers	Affirmative vote of a majority of votes cast	No effect	No effect
3.	Ratification of the Appointment of Independent Registered Public Accounting Firm	Affirmative vote of a majority of votes cast	No effect	Not applicable

⁽¹⁾ For purposes of determining the number of votes cast concerning a particular matter, only those cast “For” or “Against” are included.

⁽²⁾ Under NYSE rules that apply to brokers, Proposal 3 is considered a “routine” proposal on which brokers are permitted to vote in their discretion even if the beneficial owners do not provide voting instructions. However, Proposals 1 and 2 are not considered to be routine matters and brokers will not be entitled to vote thereon unless

Page 6

beneficial owners provide voting instructions. Accordingly, broker non-votes will not be counted toward the tabulation of votes on Proposals 1 and 2.

⁽³⁾ Directors shall be elected by a plurality of the votes cast at any meeting of stockholders for which the Secretary of the Company determines that the number of nominees exceeds the number of directors to be elected as of the date seven days prior to the scheduled mailing date of the proxy statement for such meeting.

IMPORTANT NOTICE REGARDING AVAILABILITY OF PROXY MATERIALS FOR THE ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON WEDNESDAY, APRIL 29, 2026

This Proxy Statement and our 2025 Annual Report are available on Selective’s Internet website at www.Selective.com.

INFORMATION ABOUT PROPOSAL 1

Election of Directors

Under our By-Laws, directors in uncontested elections must be elected by a majority of votes cast. A majority exists when the number of votes cast “for” a director nominee exceeds the number of votes cast “against” that director nominee. For more information on our majority voting policy, please see the section entitled, “Corporate Governance – Majority Voting for Directors in Uncontested Elections” of this Proxy Statement.

All directors stand for election for a one-year term. In all cases, each director will hold office until a successor has been elected and qualified, or until the director’s earlier resignation or removal.

The Board currently has 12 members, all of whom are standing for reelection at the Annual Meeting. Under Selective’s Amended and Restated Certificate of Incorporation and By-Laws, Selective may have a minimum of seven and a maximum of 20 directors. By majority vote, the Board may set the number of directors within this range at any time.

Process for Review and Nomination of Director Candidates

We believe that the Board’s membership should encompass a broad range of skills, expertise, industry knowledge, perspectives, and opinions. Directors should possess the highest personal and professional ethics, integrity, and values, and must be committed to representing the long-term interests of Selective and its stockholders.

The Corporate Governance and Nominating Committee is responsible for reviewing and nominating candidates to the Board. The Corporate Governance and Nominating Committee reviews all director candidates for possible nomination and election to the Board and seeks such candidates from any source, including:

◾

Directors and management;

◾

Third-party search firms that the Corporate Governance and Nominating Committee may engage from time to time for a fee to identify and assess candidates; and

◾

Stockholders.

Any stockholder proposing one or more director candidates must submit in writing all applicable information required under the Exchange Act and Selective’s By-Laws to the Chairperson of the Corporate Governance and Nominating Committee, c/o Corporate Secretary, Selective Insurance Group, Inc., 40 Wantage Avenue, Branchville, New Jersey 07890.

The Corporate Governance and Nominating Committee evaluates all candidates, including any recommended by stockholders, using the same criteria, which includes, among other things:

◾

Personal and professional integrity and character;

◾

Business judgment;

◾

Time availability in light of other commitments and dedication;

◾

Independence and conflicts of interest;

◾

Business experience, perspective, and personal expertise or experience in areas expected to contribute to the Board’s effectiveness (such as general operations, management, finance, investment, marketing, financial reporting, legal and regulatory, human resources and human

Page 7

capital management, corporate sustainability, social responsibility, technology (including artificial intelligence), cybersecurity, and risk management); and

◾

Other relevant factors that the Corporate Governance and Nominating Committee considers appropriate in the context of the needs of the Board.

The table below summarizes some of the attributes, expertise, and skills we find relevant to our business that our director nominees bring to the Board. The table does not include every attribute, expertise, or skill that each director nominee offers. The fact that a particular attribute, expertise, or skill is not listed does not mean that a director nominee does not possess it. All our director nominees exhibit high integrity, an appreciation for the benefits of varying backgrounds, experiences, and thought, innovative thinking, proven records of success, and knowledge of corporate governance requirements and best practices.

Demographics

Under our Corporate Governance Guidelines, the Corporate Governance and Nominating Committee must ensure that all pools of interviewed director candidates include individuals having a wide range of experience, perspectives, and opinions.

Fifty-eight percent of our director nominees self-identify as diverse, with five director nominees self-identifying as female, two director nominees self-identifying as racially or ethnically diverse, and one director nominee self-identifying as LGBTQ+.

The tenure of our director nominees is as follows: 17% have served five years or less; 67% have served six through ten years; and 17% have served over ten years. The ages of our director nominees are as follows: 25% are age 50 through 59; 58% are age 60 through 69; and 17% are 70 or older (in each case as of the date of this Proxy Statement).

Director Nominees

No family relationships exist among Selective’s current directors, director nominees, and executive officers.

The Board ratified the Corporate Governance and Nominating Committee’s nomination of the 12 director nominees listed below to stand for election at the Annual Meeting for terms expiring at the 2027 Annual Meeting of Stockholders or until their respective successors have been duly elected and qualified.

All 12 director nominees have consented to be named in this Proxy Statement and to serve if elected. The Board does not know of any reason a director nominee would decline or be unable to serve if elected. If a director nominee becomes unavailable or unable to serve before the Annual Meeting, the Board can reduce its size or designate a substitute director nominee. If the Board designates a substitute director nominee, proxies that would have been cast for the original director nominee will be cast for the substitute director nominee unless contrary instructions are given.

As a senior global advisor and managing partner at Deloitte for 38 years, he advised public companies on various strategic issues relevant to Selective, particularly human capital and benefit plan issues. Deloitte grew rapidly during his tenure as Global Managing Partner, and he was responsible for attracting, developing, and retaining top human capital.

TRANSACTIONS WITH RELATED PERSONS

Review, Approval, or Ratification of Transactions with Related Persons

Selective has a written Related Person Transactions Policy and Procedures (the “Related Person Policy”). The Related Person Policy defines “Related Person Transactions” as any transaction, arrangement, or relationship in which Selective or any of its subsidiaries was, is, or will be a participant and the amount involved exceeds $20,000, and in which any “Related Person” had, has, or will have a direct or indirect interest. A “Related Person” under the Related Person Policy is generally: (i) any director, executive officer, or nominee to become director of Selective or an immediate family member of any such person; (ii) a beneficial owner of more than 5% of Selective’s common stock or an immediate family member of any such beneficial owner; and (iii) any firm, corporation, or other entity in which any person included in (i) or (ii) is employed or is a general partner or principal or in a similar position or in which such person is a 5% or greater beneficial owner.

Under the Related Person Policy, the Audit Committee (or Chairperson of the Audit Committee if between meetings) must approve Related Person Transactions. In its review, the Audit Committee considers all available relevant facts and circumstances of the proposed transaction, including (i) the benefits to Selective, (ii) the impact on a director’s independence, (iii) the availability of other sources for comparable products and services, (iv) the terms of the transaction, and (v) the terms available to unrelated third parties or employees generally. No Audit Committee member may participate in any review, consideration, or approval of any Related Person Transaction in which such director or any of their immediate family members is the Related Person. The Audit Committee only approves Related Person Transactions that it considers are in, or not inconsistent with, the best interests of Selective and its stockholders.

The Selective Insurance Group Foundation

In 2005, we established a private foundation, now named The Selective Insurance Group Foundation (the “Foundation”), under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the “Code”). The board of directors of the Foundation is comprised of some of the officers of Selective and its insurance subsidiaries. We contributed $2.1 million to the Foundation in 2025.

Director Independence

Our securities are listed on the Nasdaq Stock Market (“Nasdaq”), and we use the standards of “independence” prescribed by rules set forth by Nasdaq. Under Nasdaq rules, a majority of a listed company’s board of directors must be comprised of independent directors. Under Nasdaq rules, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, such person does not have a relationship that would interfere with the exercise of independent judgment in carrying out a director’s responsibilities. Our Board has determined that all current directors¹ are independent under applicable Nasdaq and SEC rules and regulations – except our CEO, Mr. Marchioni. In making its determination, the Board considered disclosures each director made related to various transactions, relationships, or arrangements involving Selective. Disclosures by the following three directors required analysis:

Robert Kelly Doherty: Mr. Doherty’s son is a Partner for Goldman Sachs Group, Inc. (“Goldman”). In 2023, Selective engaged Goldman as its investment banking advisor. Goldman received underwriting fees in connection with Selective’s senior notes issuance in February 2025. In 2025, Selective and its subsidiaries migrated their money market fund portal to Goldman’s Mosaic platform. Our use of Goldman’s Mosaic platform did not result in any payments from us to Goldman. From time to time, we purchase Goldman issued securities.
