**PROXY STATEMENT**

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

**GENERAL INFORMATION ABOUT SELECTIVE'S ANNUAL MEETING**

<u>WHEN AND WHERE IS THE ANNUAL MEETING?</u>

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.

<u>WHEN IS THIS PROXY STATEMENT BEING MAILED OR RELEASED TO STOCKHOLDERS?</u>

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

<u>WHO IS ENTITLED TO VOTE AT THE ANNUAL MEETING?</u>

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.

<u>WHO IS SOLICITING MY PROXY TO VOTE MY SHARES AND WHEN?</u>

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.

<u>WHAT IS THE COST OF SOLICITING PROXIES AND WHO IS PAYING FOR THE COST?</u>

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.

<u>WHAT ARE THE REQUIREMENTS FOR BUSINESS TO BE CONDUCTED AT THE ANNUAL MEETING?</u>

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.

<u>HOW DO STOCKHOLDERS ATTEND THE VIRTUAL ANNUAL MEETING?</u>

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.

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.

<u>HOW DO STOCKHOLDERS ASK QUESTIONS AT THE ANNUAL MEETING?</u>

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. <u>ELECTION OF DIRECTORS</u>**

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:

---

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

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. <u>APPROVAL, ON AN ADVISORY BASIS, OF THE 2025 COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS</u>**

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. <u>RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM</u>**

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**

<u>HOW DO I VOTE?</u>

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>BY MAIL</u> (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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <u>BY TELEPHONE</u> (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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>BY INTERNET</u> (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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. <u>BY VIRTUAL PARTICIPATION</u> (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.

<u>HOW DO I REVOKE MY PROXY OR CHANGE MY VOTING INSTRUCTIONS?</u>

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; |

---

◾ 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.

<u>HOW WILL PROXIES BE VOTED IF I GIVE MY AUTHORIZATION?</u>

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.

<u>WHAT IF MY SHARES ARE NOT REGISTERED IN MY NAME?</u>

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.

<u>HOW WILL VOTES, ABSTENTIONS, AND BROKER NON-VOTES BE COUNTED?</u>

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.

<sup>(1)</sup> For purposes of determining the number of votes cast concerning a particular matter, only those cast "For" or "Against" are included.

<sup>(2)</sup> 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

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

<sup>(3)</sup> 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.

***<u>Process for Review and Nomination of Director Candidates</u>***

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

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.

***<u>Demographics</u>***

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).

***<u>Director Nominees</u>***

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.

**TRANSACTIONS WITH RELATED PERSONS**

*<u>Review, Approval, or Ratification of Transactions with Related Persons</u>*

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.

*<u>The Selective Insurance Group Foundation</u>*

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.

*<u>BlackRock</u>*

BlackRock, a leading publicly traded investment management firm, has purchased our common shares in the ordinary course of its investment business and has previously filed Schedules 13G/A with the SEC. On January 23, 2024, BlackRock filed a Schedule 13G/A reporting that it is deemed to be the beneficial owner of in excess of 5% of the outstanding shares of Selective common stock. In connection with purchasing our common shares, BlackRock filed the necessary filings with insurance regulatory authorities. On the basis of those filings, BlackRock is deemed not to be a controlling person for the purposes of applicable insurance law.

We are required to disclose related-party information for our transactions with BlackRock. BlackRock is highly regulated, serves its clients as a fiduciary, and has a diverse platform of active (alpha) and index (beta) investment strategies across asset classes that enables it to tailor investment outcomes and asset allocation solutions for clients.

***<u>Director Independence</u>***

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 directors<sup>1</sup> 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.

<sup>1</sup> The Board determined that each of the following current directors are independent: Mses. Bacus, Mitchell, Nicholson, Parsons, and Sampson and Messrs. Aijala, Cavanaugh, Doherty, McCarthy, Mills, and Scheid. Additionally, the Board determined that (i) Mr. Urban, who retired from the Board effective April 30, 2025, was independent during his tenure as a director, and (ii) Mr. Coaxum, who resigned from the Board effective July 30, 2025, was independent during his tenure as a director.

Mr. Doherty's son has an insurance policy with a Selective insurance subsidiary, which was obtained in the normal course through an independent agent, for which he pays a standard market-based premium. As (i) neither Mr. Doherty nor his son have any involvement in the above Goldman transactions, (ii) the revenue is immaterial to Goldman, and (iii) Mr. Doherty had no involvement in his son's procurement of the insurance policy, its pricing, or any other matters relating to the policy, the Board determined that these transactions do not affect Mr. Doherty's independence.

H. Elizabeth Mitchell: In determining that Ms. Mitchell is an independent director, the Board considered that she serves as a director of the Principal Financial Group ("Principal"). In connection with Principal's acquisition of Wells Fargo's trust business, bank accounts for our deferred compensation plan and certain state deposit bonds were transferred to the Principal. Ms. Mitchell had no involvement with the establishment of the bank accounts or the procurement of the state deposit bonds. In 2025, the total fees associated with these arrangements were approximately $19,000. Accordingly, the Board determined that Ms. Mitchell's relationship with the Principal does not affect her independence.

The Board also considered that Ms. Mitchell's brother is Vice President, Customer Excellence Group, Field Operations for Servicenow, Inc. ("Servicenow"). At the recommendation of, and through, one of our information technology vendors, we purchased software licenses and related software support services of Servicenow. The total amounts paid to the recommending vendor for Servicenow-related products and services in 2025 was approximately $772,300, less than 0.01% of Servicenow's 2025 total revenues. As neither Ms. Mitchell nor her brother had any involvement with these immaterial transactions, the Board determined that these transactions do not affect Ms. Mitchell's independence.

Kate E. R. Sampson: Ms. Sampson's sister-in-law is employed as a Partner at the law firm of Nutter McLennan & Fish, LLP ("Nutter"). In 2025, Selective paid less than $4,000 to Nutter for legal services. As (i) Ms. Sampson had no involvement in Selective's engagement of Nutter, (ii) her sister-in-law does not advise Selective, (iii) the business relationship pre-dated Ms. Sampson's election to the Board, and (iv) the amount of fees is immaterial, the Board determined that the transaction does not affect Ms. Sampson's independence.

All members of the Audit Committee, the Corporate Governance and Nominating Committee, and the Compensation and Human Capital Committee are independent directors under applicable Nasdaq and SEC rules and regulations.

**CORPORATE GOVERNANCE**

***<u>Corporate Governance Guidelines</u>***

Selective's Corporate Governance Guidelines are available for review on Selective's website at *www.selective.com/investors/corporate-governance*.

***<u>Majority Voting for Directors in Uncontested Elections</u>***

The Board has adopted a majority voting policy for uncontested elections of incumbent directors. To be reelected to the Board, an incumbent director must receive a majority vote by stockholders, unless the Corporate Secretary determines that the number of director nominees exceeds the number of directors to be elected. If any incumbent director nominee receives less than a majority of votes cast, the following process must be followed:

◾ The incumbent director must tender their resignation to the Chairperson of the Board within five days following the certification of the election results.

---

| | |
|:---|:---|
| ◾ | Within 45 days after the stockholders' meeting, the Corporate Governance and Nominating Committee will make a recommendation to the Board regarding whether to accept the director's resignation. In making its recommendation to the Board, the Corporate Governance and Nominating Committee may consider any factors it deems relevant and a range of possible alternatives concerning the director's tendered resignation. |

---

---

| | |
|:---|:---|
| ◾ | Within 90 days after the stockholders' meeting, the Board shall formally act on the Corporate Governance and Nominating Committee's recommendation and, within four business days of doing so, shall file with the SEC a Current Report on Form 8-K, disclosing its decision, the rationale for its decision, and the process it followed in deciding to accept or reject the director's tendered resignation. |

---

---

| | |
|:---|:---|
| ◾ | Any incumbent director who fails to receive a majority of votes cast and tenders a resignation may not participate or vote in the deliberations of the Corporate Governance and Nominating Committee or the Board related to their resignation. If every member of the Corporate Governance and Nominating Committee fails to receive a majority vote at the same stockholders' meeting, then the independent directors who received a majority vote and any independent directors who did not stand for reelection must appoint from themselves an *ad hoc* Board committee to consider the tendered resignations and make a recommendation to the Board whether it should accept them. If fewer than three directors would constitute an *ad hoc* committee, the entire Board (other than the individual director whose resignation is being considered) will make the determination to accept or reject the director's resignation. |

***<u>Board Refreshment</u>***

While the Board recognizes the importance of Board refreshment, it does not believe that it should limit the number of terms for which an individual may serve as a director. Directors who have served on the Board for an extended period have institutional knowledge and can provide valuable insight into the operations and future of Selective based on their experience with and understanding of Selective's history, policies, and objectives. The Board believes that, as an alternative to term limits, it can ensure that the Board continues to evolve and adopt new viewpoints, when appropriate, through its evaluation and nomination processes, and its mandatory retirement age policy. As previously disclosed, in January 2026, we amended our Corporate Governance Guidelines and By-Laws to provide that no person who has attained their 75<sup>th</sup> birthday is eligible for election as a director. The Board believes that increasing the retirement age from 72 to 75 helps to ensure that the Board includes the requisite institutional knowledge to support strategic continuity and ongoing performance oversight, while also recognizing the importance of bringing fresh perspectives and ideas to the Boardroom. This change is intended to ensure that the Board remains both effective and forward-looking.

***<u>Overboarding: Limits on Outside Board Memberships</u>***

The Board recognizes that a director's ability to fulfill their responsibilities as a member of the Board can be impaired if the director serves on numerous other boards or board committees. Accordingly, our Corporate Governance Guidelines limit the number of public company directorships that a director may hold. Pursuant to our Corporate Governance Guidelines, directors are not permitted to serve on the boards of more than four public companies (including the Board); provided that any director employed as a chief executive officer of a public company is not permitted to serve on the boards of more than two public companies (including the Board). A director must advise the Lead Independent Director, the Chairperson of the Board, or the Chairperson of the Corporate Governance and Nominating Committee before accepting an invitation to serve on another public or private company board, so the Board can determine that no actual or potential conflicts of interest exist and that the proposed board service does not interfere with their duties and obligations as a Selective director. Service on boards and board committees of other companies must be consistent with our conflict of interest and related person transactions policies.

***<u>Board Meetings and Committees</u>***

The Board held six meetings in 2025, and the independent directors met four times without management present. All directors attended at least 75% of the aggregate number of Board and their respective committee meetings during 2025, with average attendance over 99%. While we do not have a formal policy on director attendance at annual meetings of stockholders, we expect all directors to attend such meetings. All then-serving directors virtually attended the 2025 Annual Meeting of Stockholders.

The Board has six standing committees:

◾ Audit Committee;

◾ Corporate Governance and Nominating Committee;

◾ Compensation and Human Capital Committee;

◾ Executive Committee;

◾ Finance and Investments Committee; and

◾ Risk Committee.

The Corporate Governance and Nominating Committee is responsible for evaluating and making recommendations to the Board concerning the appointment of directors to the six committees and the selection of committee chairpersons. The Board generally favors the periodic rotation of committee chairpersons, but also recognizes that it may not always be in Selective's best interest to change a Board committee chairperson, such as when a director has special knowledge or experience. It is anticipated that Board committee chairpersons will serve up to an average of approximately five consecutive years to facilitate rotation of committee chairpersons, while maintaining experienced leadership.

The following tables provide information on each of the six standing committees and its current members:

***<u>Board Leadership Structure</u>***

Our two principal Board leadership positions are: (i) Board Chairperson; and (ii) Lead Independent Director.

Our Corporate Governance Guidelines do not require the separation of the offices of the Board Chairperson and the CEO. Instead, the Board regularly evaluates and decides whether the same person should hold the offices of Board Chairperson and CEO. Our Board has determined that it is appropriate and in the best interests of Selective and its stockholders for Mr. Marchioni to serve as both CEO and Board Chairperson given his institutional and industry knowledge. Our Board believes that our current leadership structure fosters responsive and strong leadership for Selective.

As discussed in greater detail below, our current governance structure establishes a dynamic leadership role for the Lead Independent Director, which, together with independent committee leadership, provides a meaningful counterbalance to the CEO Chairperson and maintains independent and effective oversight of management.

<u>CEO and Board Chairperson Responsibilities</u>

When the CEO serves as the Board Chairperson, as is the current structure, they are responsible for oversight and guidance of Selective's management and overall corporate performance. The CEO Chairperson leads the Board and facilitates intra-Board communication in overseeing Selective's strategy and long-term and short-term goals, and fosters ethical and responsible corporate culture and decision-making throughout Selective. Specific duties of a Board Chairperson include:

◾ Consistent with the Corporate Governance Guidelines, coordinating with the other directors, the Lead Independent Director, and management in preparation of Board and Board committee agendas and meeting materials;

◾ Presiding over all Board and stockholder meetings;

◾ Recommending actions to improve the effectiveness and performance of the Board;

◾ In conjunction with the Lead Independent Director, serving as a spokesperson for the Board and meeting with stockholders as required; and

◾ Assisting the Lead Independent Director and Chairperson of the Corporate Governance and Nominating Committee in recruiting potential candidates to the Board and in recommending appointments to various Board committees.

<u>Lead Independent Director Responsibilities</u>

Our Corporate Governance Guidelines provide that when the Board does not have an independent Chairperson, the Board will appoint an independent director to be the Lead Independent Director. Mr. Doherty is our Lead Independent Director and has served in that role since 2022. The Lead Independent Director is responsible for coordinating the activities of the independent directors and performing various other duties, including:

◾ Presiding at all meetings of independent directors, as appropriate, and providing prompt feedback to the Chairperson and/or CEO;

◾ Serving as a point of contact for Board members to raise issues that they may not be able to readily address with the Chairperson and/or CEO;

◾ Ensuring that matters of importance to the directors are placed on the Board's meeting agendas;

◾ Assuring that the Chairperson and/or CEO understand the Board's views on all critical matters;

◾ Assuring that the Board understands the Chairperson's and/or CEO's views on all critical matters;

◾ Calling executive sessions of the independent directors and serving as the chairperson of such meetings;

◾ Assisting the Corporate Governance and Nominating Committee Chairperson in overseeing the annual Board and committee self-evaluation process; and

◾ Assisting the Corporate Governance and Nominating Committee Chairperson in overseeing the director selection process.

It is anticipated that the Lead Independent Director will serve up to approximately five consecutive years to facilitate the rotation of the Lead Independent Director position while maintaining experienced leadership; however, the Board may extend such tenure consistent with good governance practices, including to further strategic objectives or address external factors affecting Selective.

***<u>Board and Committee Multi-Step Evaluation Process</u>***

The Corporate Governance and Nominating Committee conducts annual self-assessments and evaluates its effectiveness and the effectiveness of the full Board and its other committees. The process, enhanced based on feedback from the prior-year assessments, is outlined below:

***<u>Continuing Education for Directors</u>***

Selective provides continuing education opportunities for directors, including a mix of in-house and third-party presentations and programs. We are members of the National Association of Corporate Directors ("NACD"), through which our Directors have access to NACD continuing education programming, including on topics such as corporate governance, cybersecurity, and artificial intelligence. We reimburse directors for reasonable expenses incurred in connection with continuing education courses or programs related to their Board service.

<u>Sustainability and Social Responsibility</u>

We integrate sustainability principles into our business and partner with key stakeholders to develop solutions that enhance resilience, well-being, and customer service. Focus areas include (i) supporting and investing in our workforce to create a highly engaged and inclusive team of employees and leaders who will guide us into the future, (ii) understanding and addressing the environmental impact climate change has or could have on our business and operations, and (iii) providing customers with empathetic claims service and risk mitigation solutions.

<u>Helping Our Customers</u>

We provide customers and distribution partners with services and educational resources to help mitigate potential risks. Our risk management initiatives include proactively providing policyholders with notifications and alerts, identifying risks, mitigating potential losses, and providing tools and technologies that improve safety and reduce losses. Our Risk Management Specialists visit designated customers' places of business to advise on reducing the risk of loss for property or casualty claims. Selective's Risk Management Center offers Standard Commercial Lines customers seamless, on-demand access to a curated selection of self-service risk management resources. These resources address aspects of customers' businesses aligned with the specific insurance coverages that we provide. We are committed to delivering a superior omni channel customer experience, supported by our people and technology. Our Claims team responds promptly to help customers recover after experiencing loss. Our distribution partners recognize our exceptional customer service, delivered primarily through our field-based model, and consider us a highly service-oriented carrier.

<u>Developing Our Employees</u>

A core organizational priority is to build a more connected, accountable, and empowered organization by developing talent and aligning on prioritized goals. We continue to invest significantly in employee training programs and prioritize their development to position our talent for future opportunities and leadership. See below under the "Human Capital" section for further information on these efforts.

<u>Supporting Our Communities</u>

Through the Foundation, we donate to non-profit organizations that promote civic responsibility, support home, auto, and business safety, and provide health and human services. The Foundation's mission is to empower safe, sustainable, just, and inclusive communities where we – and our customers and agents – live and work.

Selective invests in indirect state and federal incentives to finance programs with social benefits or objectives. For example, Selective has invested in low-income housing tax credits, historic property credits, rural investment programs, economic redevelopment credits, renewable energy credits, and scholarship tax credit programs. We also coordinate employee volunteerism to support local charities.

<u>Managing Climate Risk</u>

We protect thousands of individuals and businesses against the financial impact of covered losses, including catastrophic events. Climate change increases the unpredictability of weather-related loss frequency and severity, posing a long-term risk to our customers' businesses and lives – and our profitability. We aim to mitigate climate change impact by (i) prudently overseeing and managing catastrophe risk exposure, (ii) providing our customers with responsive claims handling, risk management services, and proactive weather alerts, (iii) preparing for the continuing transition to clean energy, and (iv) reducing our carbon footprint. Understanding and helping mitigate climate change perils for our business and customers is core to our operations and strategy. We believe that these efforts (i) demonstrate responsible corporate action to mitigate climate change impact and (ii) will contribute to sustained superior financial and operating performance over time that will reward our stockholders.

In addition to mitigating insurance operations and investment risk, we:

---

| | |
|:---|:---|
| ◾ | Have robust plans for operational continuity if we suffer unforeseen or catastrophic events. We have business continuity plans for our key data processing facility (Disaster Recovery Plan), the leadership team (Executive Crisis Management Plan), and significant operational areas. We review, update, and test these plans at least annually. Our tests include "tabletop" exercises and planned hands-on tests. |

---

---

| | |
|:---|:---|
| ◾ | Track our Scope 1 and Scope 2 greenhouse gas ("GHG") emissions, which are relatively low compared to companies in other industries because we are an insurance holding company. Our Scope 1 emissions include consumption of natural gas, diesel, refrigerant, and the fuel employees use for work-related travel in company cars. Our Scope 2 emissions are tied to our electricity usage. |

---

◾ Built solar photovoltaic facilities at our Branchville office. In 2025, these systems generated approximately 3.3 million kWh of electricity, which we sell to others, together with the right to state that we use renewable energy.

We plan to continue reducing our carbon emissions relative to our revenues over the long term. We have developed initiatives that we expect will reduce GHG emissions over time. Some include:

◾ Upgrading our Branchville office building management system, which should reduce heating and cooling natural gas consumption;

◾ Making efforts to transition our Company cars from gasoline to hybrid vehicles; and

◾ Migrating our information technology systems from our Branchville data center to the cloud.

We have also implemented several initiatives to lower our environmental impact, including:

◾ Enhanced waste management and recycling;

◾ Implemented initiatives to reduce the use of paper within our business;

◾ Conversion of all Branchville office light bulbs to LED;

◾ Hybrid work schedule for office-based employees;

◾ Repurposing commingled recyclables;

◾ Installed electric vehicle charging stations for employee use;

◾ Elimination of Styrofoam products in our cafeteria;

◾ Recycling and more efficient energy use of electronic equipment; and

◾ Reducing our water usage through automatic plumbing features.

The table below outlines strategically important sustainability categories and our related actions and areas of focus:

***<u>Human Capital</u>***

We understand that investing in our workforce and fostering a positive employee experience enhances our team's well-being and contributes to superior, longer-term financial performance. We are committed to maintaining a safe and inclusive workplace for our approximately 2,800 employees. In 2025, we were (i) designated as a Great Place to Work Certified<sup>TM</sup> organization for the sixth consecutive year and (ii) recognized by Forbes as one of "America's Best Mid-Size Employers" for the fifth time.

<u>Physical, Social, and Financial Well-Being of our Employees</u>

We prioritize our employees' physical, social, and financial well-being, which we believe helps us attract and retain superior talent. We are committed to paying competitively, regularly analyzing compensation and taking appropriate action to support internal equity and external market alignment. Our financial benefit programs are designed to support the fiscal health of our employees and their families. These include a 401(k) plan with non-elective and employer matching contributions, an employee stock purchase plan with discounted pricing, and tuition reimbursement and student loan repayment programs for eligible employees. Most employees are eligible to participate in our annual cash incentive program, which is funded and paid based on their performance and our achievement of established financial and strategic objectives. Employees of certain levels are also eligible to participate in our long-term stock-based incentive compensation program and non-qualified deferred compensation plan.

We also offer competitive and convenient health and wellness programs. To support our employees' social and emotional well-being, we encourage connections with their colleagues and communities through various programs, including paid time off for volunteering, matching charitable donations, employee engagement events, employee resource and affinity groups, and unique programming to meet employee needs.

<u>Talent Development and Employee Retention</u>

We dedicate significant time and resources to (i) training and development, enabling our employees to fulfill their professional potential and have rewarding careers and (ii) retaining our best talent and fostering a positive work-life balance. We are committed to ongoing employee learning, personal growth, and continuous improvement. Our employees have access to a wide range of resources, including live instructor-led and online skills training courses. We also have leadership and talent development programs and initiatives for all levels of the organization. Examples include our (i) Next Generation of Leaders program, which identifies early- and mid-career management opportunities for focused development and future senior leadership preparation, (ii) RISE (Retain Include Support Engage) program, an accelerated professional development program for individual contributors interested in first-level management positions, (iii) Accelerate program, which provides training for new managers on leadership skills and techniques, and (iv) our Ignite Internship and Momentum Trainee programs, which are early career programs that help develop our future talent pipeline.

As of December 31, 2025, we had approximately 2,800 employees; 1,380 were home-based, 810 were in our regional offices, and the remainder were in our corporate office. Our Flexible Work Location Policy requires most office-based non-management employees to be in their assigned office 40% of the time, and management employees in the office 60% of the time. Our 2025 employee turnover rate was approximately 12%, compared to approximately 10% in 2024. Employees with over 20 years of service represented approximately 13% of our workforce as of December 31, 2025.

<u>Engagement and Inclusion</u>

Building a connected, accountable and empowered organization by developing talent and aligning on prioritized goals is one of our organizational priorities. We employ strategies to create an inclusive workplace culture and attract and retain employees through recruiting, onboarding, training, promotion practices, professional development, engagement surveys, retention interviews, employee resource groups, and competitive compensation and benefits. Collaboration among employees with varied backgrounds fosters innovation, improving operational performance, product development, customer experience, market opportunities, and profitability. Inclusive leadership training is made available to all newly-promoted officers, managers, and supervisors. These efforts aim to enhance engagement and create a workplace where everyone feels valued and empowered. At the Board level, the Corporate Governance and Nominating Committee manages a robust process to recruit new directors with a broad range of skills, expertise, industry knowledge, perspectives, and opinions.

As of December 31, 2025, women represented 57% of our non-officer workforce and 37% of our officers. Approximately 25% of our workforce identified as Black, Latin, Asian, or another ethnicity at year-end 2025.

**RISK MANAGEMENT**

***<u>Enterprise Risk Management</u>***

We believe a high-functioning, effective Enterprise Risk Management ("ERM") program is achieved when risk management is an organizational cultural value and the shared responsibility of every employee. We have developed processes and tools intended to support a risk management culture and create a robust organizational ERM framework. We have also designed our compensation policies and practices, governance framework, and Board leadership structure to support our overall risk appetite and strategy.

We use ERM as part of our governance and control process to take an entity-wide view of our major risks and their potential impact. We designed our ERM framework to identify, measure, report, and monitor these risks and develop appropriate responses to support the successful execution of our business strategies.

Our Board oversees our ERM process, and all Board committees oversee risks specific to their areas of supervision and report their activities and findings to the entire Board. To assist the Board in overseeing the Company's operational activities and identifying and reviewing related risks, the Board formed the Risk Committee in 2024. The Board's Risk Committee is responsible for overseeing Selective's enterprise risk management framework and practices and makes regular reports to the entire Board.

Management maintains an Executive Risk Committee ("ERC") that is responsible for the holistic monitoring and supervision of our risk profile and determining future risk management actions supporting our overall risk profile. The ERC provides management oversight of our ERM function and is responsible for maintaining operational processes and controls designed to identify, mitigate, and manage risks that could materially impact Selective. The ERC relies on several management committees to analyze and manage specific major risks. The ERC meets quarterly, and additionally as appropriate, to review and discuss various topics and the interrelation of our significant risks, including capital modeling results, capital adequacy, risk metrics, emerging risks, and sensitivity analysis. The Chief Risk Officer provides reports to the Board or the appropriate Board committee on the ERC's activities, analyses, and findings, providing quarterly updates on specific risk metrics.

For more information about our ERM function, see the "Corporate Governance, Sustainability, and Social Responsibility" section under "Item 1. Business." of our 2025 Annual Report.

***<u>Cybersecurity and Artificial Intelligence Oversight</u>***

The Board receives regular updates on the strength of our cyber risk control environment, emerging cyber threat issues, and the results of external assessments by outside security consultants. In assisting the Board in overseeing our operational activities and identifying and reviewing related risks, the Risk Committee is responsible for overseeing our cyber risks and strategy. Two directors have earned cybersecurity oversight certifications from a corporate directors' organization. For more information about cybersecurity risk management and strategy, please refer to "Item 1C. Cybersecurity." of our 2025 Annual Report.

The Board also receives regular reports on the organization's use of artificial intelligence ("AI") solutions and related risks. We maintain a cross-disciplinary Artificial Intelligence and Model Governance Committee, accountable to the ERC, to implement and administer governance over the acquisition, creation, deployment, use, and reliance on internal and external models in the execution of insurance activities. Our governance framework is aligned with the National Institute of Standards and Technology (NIST) AI Risk Management Framework controls. Three directors have earned AI oversight certifications from corporate governance organizations.

For information about how the Board oversees sustainability-related risks, please refer to the "Sustainability and Human Capital" section of this Proxy Statement.

***<u>Compensation Risk Assessment</u>***

We do not believe that risks arising from our compensation policies and practices are reasonably likely to have a material adverse effect on our operations or results. Accordingly, no material adjustments were made to our compensation policies and practices because of our risk profile.

To make this determination, we assessed the risks of our compensation policies and programs. In assessing these risks, we considered that we operate in an industry based almost entirely on managing risk, and our risk management framework is robust. We considered the following:

---

| | |
|:---|:---|
| ◾ | The compensation policies and practices for employees of our reportable segments are similar. Our insurance operations, which sell property and casualty insurance products, are subject to, among other things, risks related to significant competition, extensive losses from catastrophic events, and emerging risks. Our investment segment, which invests premiums collected by the insurance operations and proceeds from capital transactions, is subject to, among other things, global economic risks, such as adverse impacts from governmental monetary policies, and risks inherent in the equity and debt markets; |

---

◾ Our compensation policies are consistent with our overall risk structure, and we award a significant portion of our senior officers' compensation based on the accomplishment of financial performance goals measured over a three-year period; and

---

| | |
|:---|:---|
| ◾ | In addition to designing our compensation policies and practices to motivate our employees to take appropriate levels of risk, we have developed a set of controls and governance processes to manage our risk profile. These include escalation processes based on various levels of individual authorities, a comprehensive group of management and Board committees that focus on analysis, management, and reporting of specific major risks, and robust internal audit processes. These controls and governance processes, along with our risk management process, are designed to help us understand and respond to changes in our risk profile and effectively manage our risk profile consistent with our risk appetite. |

---

We also considered our overall compensation program, including:

◾ The features of our compensation program and whether they align with our compensation philosophy;

---

| | |
|:---|:---|
| ◾ | The compensation program's multiple financial and strategic measures that balance profitability and growth. We base our financial goals on the U.S. generally accepted accounting principles ("GAAP") combined ratio,<sup>2</sup> which is an accepted insurance industry standard of profitability, non-GAAP operating return on common equity ("ROE"), statutory net premiums written ("NPW") growth, and statutory operating return on policyholder surplus. We base our strategic goals on measures intended to generate profitable growth, such as pricing, customer experience, and operational efficiency; |

---

◾ The maximum potential payments under our compensation plans;

◾ The mix of fixed versus variable compensation;

◾ The balance between cash and equity compensation;

◾ The ratio of compensation based on long-term versus short-term performance metrics; and

◾ The timing of equity award grants and vesting.

We also considered that we adjust our compensation programs from time-to-time as risks in our industry and reportable segments change to help ensure that compensation and risk remain appropriately aligned.

<sup>2</sup> The combined ratio is the property and casualty insurance industry standard measure of underwriting profitability. A combined ratio under 100% indicates that an insurance company is generating an underwriting profit and a combined ratio over 100% indicates that an insurance company is generating an underwriting loss.

Finally, we reviewed our various risk mitigation strategies in the compensation context, including:

◾ The stock ownership and retention requirements for management outlined in the section entitled, "Executive Stock Ownership and Retention Requirements" of this Proxy Statement;

◾ The independent oversight of compensation programs by the Compensation and Human Capital Committee, including oversight of goals and performance measures; and

◾ The Board's role in risk oversight, which includes receiving, analyzing, and inquiring about reports from its committees, including the Compensation and Human Capital Committee and the Risk Committee, and management's ERC.

We will continue to assess the risks of our compensation policies and programs going forward.

**STOCKHOLDER COMMUNICATIONS**

Stockholders and other interested parties may send communications to the Board, a committee of the Board, or individual directors in writing to c/o Corporate Secretary, Selective Insurance Group, Inc., 40 Wantage Avenue, Branchville, New Jersey 07890 or by e-mail to <u>corporate.governance@Selective.com</u>. The Corporate Secretary will review each communication received solely to determine if appropriate. The Board has determined that the following types of communication are not related to the Board's duties and responsibilities and are not appropriate: spam and similar junk mail and mass mailings, unsolicited advertisements or invitations to conferences or promotional material, product complaints, resumes or other job inquiries, and surveys.

**CODE OF CONDUCT**

Selective has adopted a Code of Conduct that establishes business ethics principles that apply to all Selective personnel, including executive officers. The Code of Conduct is located on Selective's website at www.selective.com/investors/corporate-governance. Any material amendment to or waiver from the provisions of the Code of Conduct that applies to Selective's executive officers will be posted to Selective's website.

**INSIDER TRADING POLICY**

Selective has adopted an Insider Trading Policy that applies to all employees, including officers, and directors of the Company and its subsidiaries. We believe that the Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations with respect to the purchase, sale and/or other dispositions of Selective's securities, as well as the applicable rules and regulations of Nasdaq. A copy of the Insider Trading Policy is filed as Exhibit 19 to our Annual Report on Form 10-K.

**EXECUTIVE COMPENSATION**

**COMPENSATION DISCUSSION AND ANALYSIS**

**EXECUTIVE SUMMARY**

This Compensation Discussion and Analysis provides our stockholders information about our 2025 compensation program for the following named executive officers ("NEOs"):

◾ John J. Marchioni, Chairman, President and CEO;

◾ Patrick S. Brennan, Executive Vice President and Chief Financial Officer;

◾ Joseph O. Eppers, Executive Vice President, Chief Investment Officer;

◾ Brenda M. Hall, Former Executive Vice President, Chief Operating Officer, Standard Lines<sup>(1)</sup>; and

◾ Michael H. Lanza, Executive Vice President, General Counsel and Chief Compliance Officer.

<sup>(1)</sup> Ms. Hall served as the Company's Chief Operating Officer, Standard Lines until her retirement effective January 5, 2026.

***<u>Consideration of 2025 Say-on-Pay Advisory Vote Results</u>***

Since our initial say-on-pay proposal in 2011, our stockholders have overwhelmingly supported our compensation decisions. Our NEOs' compensation was approved at the 2025 Annual Meeting of Stockholders by over 97% of votes cast. In determining our NEOs' 2025 compensation, the Compensation and Human Capital Committee ("CHCC") considered these results. Consequently, we did not materially change our 2025 compensation program and policies. We have continued to emphasize a well-calibrated and balanced combination of short-term and long-term incentive compensation, which we believe rewards our NEOs for delivering long-term stockholder value. We value our stockholders' feedback and will continue to review and consider the results of our say-on-pay proposals.

***<u>2025 Corporate Performance Results and Business Highlights</u>***

Throughout 2025, we worked to address the ongoing challenge of elevated severities driven by social inflation. For 2025, performance relative to key annual financial indicators indicated significant improvements over 2024, as we generated a GAAP ROE of 14.4% and a non-GAAP operating ROE<sup>3</sup> of 14.2%. While our 2025 combined ratio of 97.2% was slightly above our 95% long-term target, it was a significant improvement over our 2024 combined ratio of 103%. Compared to 2024, overall NPW increased by 5%, overall new business decreased by 4%, and overall renewal pure price increased by 9.5%.

<sup>3</sup> Non-GAAP operating ROE is a non-GAAP financial measure and is calculated as follows:

---

| |
|:---|
| &nbsp;&nbsp;**Non-GAAP Operating ROE:** |
| &nbsp;&nbsp;Non-GAAP Operating Income from the Performance Period |
| &nbsp;&nbsp;÷ |
| &nbsp;&nbsp;Average Common Stockholders' Equity over the Performance Period |

---

Non-GAAP operating income differs from net income available to common stockholders by the exclusion of after-tax net realized and unrealized gains and losses on investments. This non-GAAP measure is used as an important financial measure by management, analysts, and investors because the timing of realized investment gains and losses on securities in any given period is largely discretionary. In addition, net realized and unrealized gains and losses on investments could distort the analysis of trends. Non-GAAP operating ROE is not intended as a substitute for ROE that is based on net income available to common stockholders prepared in accordance with GAAP. Please refer to Selective's Annual Report on Form 10-K for the year ended December 31, 2025 for a reconciliation of Non-GAAP operating ROE to its most directly comparable financial measure calculated and presented in accordance with GAAP.

**GAAP COMBINED RATIO**

![](tm261551d2_def14a-img018.jpg)

Our after-tax net investment income was $421 million in 2025, an increase of 16% from 2024, driven by solid performance of the fixed income portfolio and growth in assets from the proceeds of the $400 million senior notes issuance and strong operating cash flow. Investment segment net investment income after-tax contributed 13.3 points of GAAP ROE in 2025. As of year-end 2025, 92% of our portfolio was invested in fixed income and short-term investments, with an average credit rating of "A+" and effective duration of 4.1 years, offering a high degree of liquidity. Risk assets, including our high-yield bond allocation within our fixed income securities portfolio, public equities, and limited partnership investments in private equity, private credit, and real asset strategies, represented approximately 10% of our investment portfolio at year-end 2025.

In 2025, our annualized total shareholder return ("TSR") was -8.8%, calculated by comparing the change in value of our common stock price and reinvested dividends. The table below shows our TSR compared to Standard & Poor's ("S&P") P&C Index annualized TSR and S&P's 500 Index annualized TSR for the last one-, three-, five-, and ten-year periods:

---

| | | | |
|:---|:---|:---|:---|
| &nbsp;&nbsp;**Time Period** | &nbsp;&nbsp;**Selective<br> Annualized TSR** | &nbsp;&nbsp;**S&P's P&C Index<br> Annualized TSR** | &nbsp;&nbsp;**S&P's 500 Index<br> Annualized TSR** |
| &nbsp;&nbsp;One-Year Period | &nbsp;&nbsp; -8.8% | &nbsp;&nbsp;10.1% | &nbsp;&nbsp;17.9% |
| &nbsp;&nbsp;Three-Year Period | &nbsp;&nbsp; -0.4% | &nbsp;&nbsp;18.2% | &nbsp;&nbsp;23.0% |
| &nbsp;&nbsp;Five-Year Period | &nbsp;&nbsp; 6.1% | &nbsp;&nbsp;18.6% | &nbsp;&nbsp;14.4% |
| &nbsp;&nbsp;Ten-Year Period | &nbsp;&nbsp;11.2% | &nbsp;&nbsp;15.6% | &nbsp;&nbsp;14.8% |

***<u>Organizational Priorities</u>***

Risk selection, granular and accurate risk pricing, and prompt fair claims adjudication are foundational capabilities we have built over many decades. We have a solid foundation but are continuing to strengthen these core competencies to compete and succeed in a rapidly evolving landscape shaped by agency consolidation; social, economic, and regulatory shifts; intensifying competition; technological advances; and changing workforce expectations.

We have established the following organizational priorities designed to sharpen alignment across the enterprise and deliver long-term sustainable performance:

◾ Relentlessly improving on the fundamentals across risk selection, individual policy pricing, and claim outcomes to enable sustainable growth and scaling;

◾ Diversifying revenue and income streams within and across our three insurance segments by driving growth within our existing product set, expanding into new products, and adding new states to our geographic footprint;

◾ Further leveraging our use of data analytics and technology, including AI, to drive operational efficiency and improved underwriting and claim outcomes; and

◾ Building a connected, accountable, and empowered organization by developing talent and aligning on prioritized goals.

These priorities guide our efforts to strengthen our business and reward our stockholders with long-term value creation.

***<u>Role and Function of the</u>*** ***<u>Compensation & Human Capital Committee (CHCC), the Compensation Consultant, and Management</u>***

The CHCC oversees executive compensation and retains an independent executive compensation consultant, Exequity LLP (the "Compensation Consultant"), to advise it on executive and director compensation matters. The Compensation Consultant (i) reviews our NEO compensation structure and amounts, (ii) prepares comprehensive competitive compensation analyses for our NEOs, (iii) provides counsel to the CHCC about award metrics, compensation components, amounts allocated to those components, and the total compensation opportunities for the CEO and the other NEOs, and (iv) attends CHCC meetings.

The Compensation Consultant has advised the CHCC since 2007. The Compensation Consultant advises the CHCC on executive and director compensation matters and does not provide any additional services to Selective. The CHCC determined that the Compensation Consultant has no conflicts of interest with Selective based on applicable SEC and Nasdaq rules.

The CHCC has full autonomy to make compensation decisions about the NEOs, incorporating information and advice from the Compensation Consultant. In 2025, Mr. Marchioni made recommendations to the CHCC regarding the other NEOs' compensation, based on his assessment of their annual performance, contributions to Selective, and potential for advancement. Mr. Marchioni did not participate in the deliberations on his compensation.

In making its compensation decisions, the CHCC also considers (i) pre-established guidelines regarding award amounts, (ii) pay levels at companies with which we compete for business and executive talent (discussed below), (iii) Selective's performance, (iv) executive retention issues, (v) internal compensation parity, and (vi) advancement in abilities, experience, and responsibilities. As part of their usual duties and responsibilities, the Executive Vice President, Chief Human Resources Officer, and certain other human resources officers provide the CHCC with information about the overall design of the executive compensation program and its components.

**<u>DESIGN CONSIDERATIONS OF SELECTIVE'S EXECUTIVE COMPENSATION PROGRAM</u>**

***<u>Selective's Executive Compensation Program Objective and Philosophy</u>***

Our executive compensation program aims to attract, retain, and motivate executive talent to drive Selective's success by creating stockholder value through profitable growth and effective risk management.

Our compensation program is designed to (i) promote and align both the short- and long-term interests of our NEOs with those of our stockholders, (ii) reward the achievement of our financial and strategic business objectives, and (iii) recognize each NEO's achievements, motivating execution of duties and responsibilities in a manner not reasonably likely to have a material adverse effect on our operations or results. We aim to provide our highly talented and qualified NEOs with competitive total compensation, based on total value and a mix of short- and long-term cash and stock-based components, compared to the compensation paid by other property and casualty insurance companies and other companies with which we compete for executive talent.

When evaluating compensation for our CEO and other NEOs, the CHCC considers (i) our overall results compared to budget and projected industry results, (ii) performance relative to our ROE target, (iii) Selective's underwriting profitability as measured by our combined ratios, (iv) our ability to profitably grow NPW, (v) our investment income performance compared to both budget and benchmark targets, and (vi) retention of top talent.

Consistent with our pay-for-performance philosophy, we link our annual incentive awards to pre-determined financial and strategic business objectives and individual contributions. We align our long-term compensation to the achievement of pre-determined specific performance measures that we believe impact the generation of long-term stockholder value.

***<u>Compensation Elements</u>***

Our executive compensation program generally consists of the following key elements selected to (i) address the market-based realities of attracting and retaining quality NEOs and (ii) align the NEOs' compensation with our stockholders' interests:

◾ Base salary;

◾ Annual cash incentive program ("ACIP") payments; and

◾ Long-term incentive program ("LTIP") awards in the form of performance-based restricted stock units and performance-based cash incentive units.

***<u>Compensation Best Practices</u>***

Our compensation program and practices feature the following best practices:

---

| | |
|:---|:---|
| &nbsp;&nbsp;**WHAT WE DO** | &nbsp;&nbsp;**WHAT WE DO NOT DO** |
| &nbsp;&nbsp;We use fixed and variable compensation components. | &nbsp;&nbsp;We do not include excise tax gross-up provisions in employment agreements. |
| &nbsp;&nbsp;We align pay with performance, with compensation weighted toward performance-based equity and performance-based cash bonus awards to NEOs. | &nbsp;&nbsp;We do not re-price stock options. |
| &nbsp;&nbsp;We have stock ownership and retention requirements for our senior executives. | &nbsp;&nbsp;We do not grant stock options at less than fair market value. |
| &nbsp;&nbsp;We have double triggers for cash and equity award payments upon a change in control under employment agreements. | &nbsp;&nbsp;We do not pay dividends on unvested stock-based awards. |
| &nbsp;&nbsp;We have a recoupment policy that provides for the clawback of certain incentive-based compensation (see section entitled, "Recoupment of Awards" of this Proxy Statement for more information). | &nbsp;&nbsp;We have not included incentive compensation in pension calculations (accrual of additional pension benefits ceased in 2016). |
| &nbsp;&nbsp;We offer very limited perquisites to executive officers. | &nbsp;&nbsp;We do not permit hedging of Selective stock by directors, officers, or employees (see section entitled, "Policy on Hedging" of this Proxy Statement for more information). |
| &nbsp;&nbsp;The CHCC engages an independent compensation consultant. | &nbsp;&nbsp;We do not guarantee annual salary increases. |

***<u>Benchmarking</u>***

When making compensation decisions, the CHCC believes it is important to have information from multiple sources about compensation practices at an array of publicly traded companies, focusing on property and casualty insurance holding companies. The CHCC believes that:

◾ Benchmarking provides the CHCC with relevant context to make appropriate compensation decisions that will help attract, retain, and motivate the key talent required to drive company performance and long-term stockholder value;

◾ Measuring our compensation against practices from two benchmark sources (see below for more details) helps ensure that the CHCC has an ample and robust assessment of our competitive compensation posture; and

◾ Considering multiple market references alleviates potential volatility inherent in a single-market data point and enhances the CHCC's decisions by allowing it to rely on a more comprehensive set of market-competitive pay boundaries.

The CHCC reviewed with the Compensation Consultant the following benchmarking information in October 2024 for purposes of establishing 2025 compensation:

---

| | |
|:---|:---|
| ◾ | Analyses of both the individual compensation elements and total compensation that we pay our NEOs compared to a peer group that consisted of companies with which we compete in the sale of products and services and for talent ("Proxy Peer Group"); and |

---

---

| | |
|:---|:---|
| ◾ | Data from a third-party vendor survey, the 2024 Property and Casualty Insurance Compensation Survey for our NEOs against a group consisting of 59 property and casualty insurance organizations, including Selective, with annual median direct written premiums of $4.4 billion and annual median revenues of $3.6 billion. |

---

As part of the 2025 compensation process, in late 2024, the Compensation Consultant furnished the CHCC with the most recent NEO compensation information available from the following:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**Proxy Peer Group\*** | &nbsp;&nbsp;**Proxy Peer Group\*** | &nbsp;&nbsp;**Third-Party<br> Vendor Survey** |
| &nbsp;&nbsp;Arch Capital Group, Ltd. | &nbsp;&nbsp;Kemper Corporation | &nbsp;&nbsp;Property and Casualty Insurance Compensation Survey |
| &nbsp;&nbsp;AXIS Capital Holdings Limited | &nbsp;&nbsp;RLI Corporation | &nbsp;&nbsp;Property and Casualty Insurance Compensation Survey |
| &nbsp;&nbsp;Cincinnati Financial Corporation | &nbsp;&nbsp;The Hanover Insurance Group, Inc. | &nbsp;&nbsp;Property and Casualty Insurance Compensation Survey |
| &nbsp;&nbsp;CNA Financial Corporation | &nbsp;&nbsp;The Hartford Financial Services Group, Inc. | &nbsp;&nbsp;Property and Casualty Insurance Compensation Survey |
| &nbsp;&nbsp;Erie Indemnity Company | &nbsp;&nbsp;United Fire Group, Inc. | &nbsp;&nbsp;Property and Casualty Insurance Compensation Survey |
| &nbsp;&nbsp;Everest Re Group, Ltd. | &nbsp;&nbsp;W. R. Berkley Corporation | &nbsp;&nbsp;Property and Casualty Insurance Compensation Survey |

\* Except with respect to the removal of Argo Group International Holdings, Ltd. following its acquisition, the Proxy Peer Group used in making 2025 compensation decisions was the same as the Proxy Peer Group used in 2024.

Information for the Proxy Peer Group companies was obtained from proxy statements and other SEC filings. This information includes data on compensation components and comparative analyses of the overall financial performance of the Proxy Peer Group. The Proxy Peer Group is comprised of companies that provide similar products, have a similar geographic market scope, and compete with us for executive talent. The Property and Casualty Insurance Compensation Survey provides supplemental data from organizations of various sizes. We also analyze data from across the property and casualty insurance industry because we strive to engage the best talent and recruit from organizations that are both smaller and larger than Selective.

In late 2025 and early 2026, to evaluate 2025 and 2026 pay decisions, including the ACIP payouts for 2025, the CHCC reviewed information (i) from the Proxy Peer Group and (ii) reported in the 2025 Property and Casualty Insurance Compensation Survey group consisting of 57 property and casualty insurance organizations, including Selective, with annual median direct written premiums of $4.1 billion and annual median revenues of $4.6 billion.

The CHCC reviewed compensation information from these two market reference sources in setting the NEOs' total compensation (consisting of aggregate base salaries, ACIP payments, and LTIP awards) 20.3% below the combined benchmark median. The components comprising NEO total compensation for 2025 differed from market to varying degrees. Specifically, base salary was 4.2% below the combined benchmark median. Driven by the 2025 financial performance indicators that reflected considerable year-on-year improvement over 2024 results, most notably improvements in GAAP combined ratio from 103.0% to 97.2% and non-GAAP operating ROE from 7.1% to 14.2%, ACIP awards were materially higher for 2025 than for 2024 but were still 35.7% below the combined benchmark median. The relative positioning of the combined base salary and ACIP awards resulted in annual total cash compensation that was 24.9% below the combined benchmark median. The grant date fair value of our 2025 LTIP awards was 13.5% below the combined benchmark median. The CHCC felt that each NEO's compensation, on an absolute basis and relative to market references, was appropriate, considering their individual accomplishments and contributions, performance relative to 2025 financial, operational, and strategic goals, and performance compared to projected industry performance.

**2025 ELEMENTS OF COMPENSATION AND ALLOCATION BETWEEN CURRENT AND LONG-TERM COMPENSATION**

The table below shows the percentages of compensation for 2025 for the CEO and the other NEOs that are fixed compensation (i.e., base salary) versus variable compensation (i.e., ACIP and LTIP), and short-term incentive compensation (i.e., ACIP) versus long-term incentive compensation (i.e., LTIP).

As indicated in the table below, the 2025 compensation allocation aligns closely with our compensation philosophy, which is designed to motivate our NEOs to achieve short- and long-term corporate objectives consistent with our stockholders' economic interests. We strive to balance pay incentive elements and performance time horizons.

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Fixed Compensation** | **Variable Compensation** | **Variable Compensation** | **Variable Compensation** |
| **NEOs** | **2025 Base Salary** | **2025 Short-Term<br> (ACIP)** | **2025 Long-Term<br> (LTIP)** | **2025 Total Variable<br> (ACIP + LTIP)** |
| John J. Marchioni | 16% | 24% | 60% | 84% |
| Patrick S. Brennan | 23% | 36% | 41% | 77% |
| Joseph O. Eppers | 28% | 35% | 37% | 72% |
| Brenda M. Hall | 28% | 23% | 49% | 72% |
| Michael H. Lanza | 39% | 26% | 35% | 61% |

---

The chart below reflects the allocation of 2025 compensation among LTIP, ACIP, and base salary for the CEO and the average of all other NEOs:

![](tm261551d2_def14a-img019.jpg)

***<u>Base Salary</u>***

Our base salary compensation is intended to provide stable, competitive compensation while considering each NEO's scope of responsibility, relevant background, training, and experience. In setting base salaries, the CHCC considers competitive market data for positions with comparable job content and overall market demand for each position. The CHCC generally believes base salaries should align with market trends for NEOs with similar responsibilities at comparable companies. When establishing the base salaries of our NEOs, the CHCC also considers:

◾ The functional role of the NEO's position;

◾ The NEO's level of responsibility;

◾ The NEO's growth in the position, including skills and competencies;

◾ The NEO's contribution and performance; and

◾ Selective's ability to replace the NEO.

Based on these considerations and their individual accomplishments and contributions as described below in the section entitled, "2025 Compensation Actions for the CEO and other NEOs," the CHCC increased the base salary rates of the following NEOs in early 2025 during our regular salary review process: Mr. Brennan, 1.5%; Mr. Eppers, 2.2%; Ms. Hall, 1.8%; and Mr. Lanza, 0.8%. Mr. Marchioni's base salary rate remained the same as for 2024.

***<u>Annual Cash Incentive Program</u>***

Our ACIP is intended to link a meaningful portion of annual cash compensation to one or more pre-established annual short-term strategic and financial organizational performance goals. For 2025, all NEOs were eligible to participate in the ACIP. As described below, the ACIP calculation for Mr. Eppers, our Chief Investment Officer, is determined under an Investment Department ACIP framework that focuses primarily on investment-related criteria. ACIP awards are granted under the Selective Insurance Group, Inc. Cash Incentive Plan, As Amended and Restated as of May 1, 2014 (the "Cash Incentive Plan").

***<u>2025 Corporate ACIP Measures</u>***

Our Corporate ACIP Measures (defined below) are established to encourage our NEOs to remain focused on particular financial and strategic objectives, even in the face of challenging circumstances in the performance year. The CHCC considers the level of achievement of the Corporate ACIP Measures when determining ACIP payments to our NEOs. The CHCC has the authority to adjust payouts in its discretion.

The Corporate ACIP plan consists of two components: financial and strategic (collectively referred to as the "Corporate ACIP Measures"). The financial component is tied to Selective's GAAP combined ratio for the performance year. The 50% target was set to a 95% combined ratio. The financial component pays 0% at a combined ratio exceeding 100% and has a maximum payout of 120% at a combined ratio of 88% or less. The strategic component opportunity ranges between 0% and 50% based on achieving targets for 11 specific measures tied to our strategic business framework, with the potential for an additional 5% if certain targets are exceeded.

The table below shows total potential Corporate ACIP payouts for NEOs at various combined ratio percentages, assuming all 11 strategic measures were fully met:

***<u>2025 Corporate ACIP Measure Results</u>***

The 2025 Corporate ACIP Measure results were based on our achievement of the financial metric, overall GAAP combined ratio, and the strategic measures, as described in greater detail below.

*<u>Financial Performance Results</u>*

For 2025, our overall GAAP combined ratio was 97.2%, representing a significant improvement compared to 103.0% for 2024, and resulting in 28 funding points for the financial performance component of the Corporate ACIP Measures.

*<u>Strategic Measures Performance Results</u>*

The table below reflects that we fully achieved nine strategic measures and partially achieved two strategic measures for the corporate functions, resulting in the strategic measures performance component of the Corporate ACIP Measures being funded at 42 points.

*<u>2025 Corporate ACIP Measure Results</u>*

For 2025, our combined Corporate ACIP Measures resulted in a total funding opportunity for Messrs. Marchioni, Brennan, and Lanza, and Ms. Hall of 70 points, consisting of 28 points for the financial measure and 42 points for the strategic measures.

***<u>2025 Investment Department ACIP Measures</u>***

The Investment Department ACIP has three main components: corporate financial, investment financial, and investment strategic. The Investment Department ACIP corporate financial measure is the same as the Corporate ACIP's, namely the GAAP combined ratio, and constitutes 10% of the calculation. For 2025, the Investment Department ACIP was modified to reduce the weighting of the corporate combined ratio metric, from 25% to 10%, improving alignment with the investment team's direct financial impact and market-competitive incentive design to support talent attraction and retention. The investment financial component constitutes 45% of the calculation and consists of after-tax net investment income and total return measures. The remaining 45% of the calculation comprises strategic initiatives that are significant to the success of the Investment Department's results.

*<u>Corporate Financial Performance Results</u>*

As noted above under the 2025 Corporate ACIP Measure Results, this measure earned 5.6 out of 10 possible points toward the Investment Department's ACIP.

*<u>Investment Financial Measure Performance Results</u>*

The table below reflects that four of the 2025 Investment Department ACIP financial measures were achieved or exceeded and one was partially achieved, resulting in 56.2 points (amounts do not foot due to rounding).

*<u>2025 Investment Department ACIP Measure Results</u>*

The 2025 Investment Department ACIP financial and strategic measures resulted in a total funding opportunity for Mr. Eppers of 5.6 points for the Corporate ACIP financial measure, 53.5 points for the Investment Department ACIP strategic measures, and 56.2 points for the Investment Department ACIP financial measures, for a combined total performance factor of 115.4 points.

***<u>2025 ACIP Payment Opportunities Awards for NEOs</u>***

The 2025 ACIP payment opportunities for the NEOs were based on competitive market levels and set as a percentage of each NEO's annual base salary. The following table lists each NEO's (i) 2025 minimum and maximum ACIP opportunities as a percentage of base salary rate, (ii) actual 2025 ACIP payment as a percentage of base salary rate, (iii) actual 2025 payment amount, and (iv) the percentage change in ACIP amount paid from 2024 to 2025:

| **Michael H. Lanza** | 0% | 150% | 67% | $400000 | 31% |

---

<sup>(1)</sup> The CHCC established the NEOs' ACIP opportunity ranges (as a percentage of base salary rate) in January 2025, which did not change from 2024. This equates to maximum potential payment amounts of $3,675,000 for Mr. Marchioni; $1,650,000 for Mr. Brennan; $690,000 for Mr. Eppers; $855,000 for Ms. Hall; and $900,000 for Mr. Lanza.

<sup>(2)</sup> Given his date of hire in October 2024, Mr. Brennan did not receive an ACIP payment for 2024; instead, he received a $500,000 cash payment in 2025, in part as a make-whole payment for compensation forfeited for leaving his prior employer that he received for 2024 pursuant to the terms of his employment agreement (the "2024 Make-Whole ACIP Payment").

**<u>ELEMENTS OF LONG-TERM COMPENSATION</u>**

***<u>Design Elements</u>***

Our long-term incentive opportunities are intended to reward our NEOs and encourage their long-term retention. By aligning financial rewards with our stockholders' economic interests, our NEOs are motivated to achieve our long-term strategic objectives and increase stockholder value. We use both cash and non-cash elements under our LTIP to deliver long-term compensation.

LTIP awards are typically granted in overlapping three-year cycles and are allocated between performance-based restricted stock units and performance-based cash incentive units. By granting performance-based restricted stock units and performance-based cash incentive units with three-year performance periods, we seek to align our economic interests with those of our stockholders and further support retention.

***<u>LTIP Award Grants</u>***

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**Performance<br> Period** | &nbsp;&nbsp;**Restricted Stock Unit Performance Measures** | &nbsp;&nbsp;**Cash Incentive Unit Performance<br> Measures** |
| &nbsp;&nbsp;01/01/23 – 12/31/25 | &nbsp;&nbsp;Generate a cumulative non-GAAP operating ROE of at least 12% (computed by excluding from the determination of average equity any unrealized gain or loss occurring after December 31, 2022), or achieve a 5% cumulative growth in policy count or statutory NPW at the end of the three-year performance period. | &nbsp;&nbsp;Cumulative TSR over the three-year performance period, and cumulative three-year statutory NPW growth and statutory operating return on policyholder surplus<sup>(1)</sup> relative to peer index. |
| &nbsp;&nbsp;01/01/24 – 12/31/26 | &nbsp;&nbsp;Generate a cumulative non-GAAP operating ROE of at least 12% (computed by excluding from the determination of average equity any unrealized gain or loss occurring after December 31, 2023), or achieve a 5% cumulative growth in policy count or statutory NPW at the end of the three-year performance period. | &nbsp;&nbsp;Cumulative TSR over the three-year performance period, and cumulative three-year statutory NPW growth and statutory operating return on policyholder surplus relative to peer index. |
| &nbsp;&nbsp;01/01/25 – 12/31/27 | &nbsp;&nbsp;Generate a cumulative non-GAAP operating ROE of at least 12% (computed by excluding from the determination of average equity any unrealized gain or loss occurring after December 31, 2024), or achieve a 5% cumulative growth in policy count or statutory NPW at the end of the three-year performance period. | &nbsp;&nbsp;Cumulative TSR over the three-year performance period, and cumulative three-year statutory NPW growth and statutory operating return on policyholder surplus relative to peer index. |

---

<sup>(1)</sup> Statutory operating return on policyholder surplus is a profitability measurement calculated by dividing statutory operating income by the average policyholder surplus during the performance period.

In determining the amount of LTIP awards granted to the NEOs in 2025, the CHCC considered several factors, including: (i) each NEO's performance during the previous year, including the achievement of departmental goals and other projects and endeavors accomplished throughout the year; (ii) each NEO's total compensation in comparison to our Proxy Peer Group and Property and Casualty Insurance Compensation Survey data; and (iii) our desire for long-term retention of high-performing executives.

*<u>Performance-Based Restricted Stock Units</u>*

Approximately 75% of the total grant date fair value of each NEO's LTIP award made in 2025 consisted of performance-based restricted stock units granted under the Selective Insurance Group, Inc. 2024 Omnibus Stock Plan (the "Omnibus Stock Plan"), subject to the following conditions:

◾ Three-year vesting period; and

---

| | |
|:---|:---|
| ◾ | Achievement at the end of the three-year period beginning on January 1, 2025 and ending on December 31, 2027, of either (i) a cumulative non-GAAP operating ROE of at least 12% (computed by excluding from the determination of average equity any unrealized gain or loss occurring after December 31, 2024), or (ii) a cumulative 5% growth in policy count or statutory NPW. |

Dividend equivalent units ("DEUs") are credited on performance-based restricted stock units at the same time and same dividend rate paid to all Selective stockholders. Payments of DEUs, which are payable in shares of Selective common stock, remain subject to the same vesting conditions and performance measures as the underlying restricted stock units. DEUs are not paid unless and until the related restricted stock units vest. Using performance-based restricted stock units aligns this component of our NEOs' compensation with overall corporate performance and stockholder interests.

*<u>Performance-Based Cash Incentive Units</u>*

The remaining approximate 25% of the total grant date fair value of each NEO's LTIP award granted in 2025 consisted of performance-based cash incentive units granted under the Cash Incentive Plan, subject to the following terms:

◾ Three-year performance period;

---

| | |
|:---|:---|
| ◾ | The value of each cash incentive unit, initially awarded at $100 per unit, increases or decreases to reflect the TSR of Selective common stock over the three-year performance period for the award beginning on January 1, 2025 and ending on December 31, 2027; and |

---

◾ The number of cash incentive units ultimately earned increases or decreases based on the performance criteria in the following table:

In establishing the 2025 peer group to compare performance and determine the ultimate number of performance-based cash incentive units earned (the "Cash Incentive Unit Peer Group"), the CHCC sought to include companies with similar premium volume, product mix, geographic operations, and independent insurance agents' product distribution. The Cash Incentive Unit Peer Group used for 2025 was consistent with that used in 2024. The Cash Incentive Unit Peer Group differs from the Proxy Peer Group, as the Proxy Peer Group also includes companies with which we compete for executive talent. The Cash Incentive Unit Peer Group consists of the following companies:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Auto-Owners Insurance Group | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Liberty Mutual Group Inc. |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cincinnati Financial Corporation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Hanover Insurance Group, Inc. |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CNA Financial Corporation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;United Fire Group, Inc. |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Donegal Insurance Group | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Utica National Insurance Group |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Erie Indemnity Company | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Westfield Group |

***<u>Timing of LTIP Awards</u>***

LTIP awards are generally granted each year after Selective releases its year-end results.

***<u>2022 LTIP Award Grant Results</u>***

The following table summarizes the achievement of the performance metrics for the 2022 LTIP award grants and the corresponding payout in 2025:

---

<sup>(1)</sup> Cash incentive unit awards are denominated in units and granted at a target amount, with an initial value of $100. The number and final value of the cash incentive units ultimately earned by the NEOs are variable, depending on the level of achievement of the underlying performance metrics.

<sup>(2)</sup> Selective's cumulative three-year statutory operating return on policyholder surplus of 32.26% positioned us in the 100<sup>th</sup> percentile of the Cash Incentive Unit Peer Group. The cumulative three-year statutory NPW growth of 45.15% placed us in the 68.29<sup>th</sup> percentile of the Cash Incentive Unit Peer Group, resulting in the earning of 133% of the cash incentive units initially granted. Please refer to the Matrix of Potential Performance-Based Cash Incentive Unit Payouts above.

**<u>2025 COMPENSATION ACTIONS FOR THE CEO AND OTHER NEOS</u>**

In making its 2025 base salary, ACIP, and LTIP compensation decisions for Mr. Marchioni and the other NEOs, the CHCC considered each NEO's overall and individual accomplishments and contributions. The required achievement of pre-determined financial and strategic goals limits our compensation program's ACIP and LTIP components. We structure our reward programs to retain and motivate our best-performing employees and those in critical positions. In balancing our strategic results achieved with ongoing price competition, the CHCC made the following compensation decisions for 2025:

Mr. Marchioni's:

◾ Base salary did not change from 2024;

---

| | |
|:---|:---|
| ◾ | ACIP payment for 2025 was 31.3% higher than his 2024 ACIP payment, driven primarily by the significant improvement in the Company's financial performance in 2025 versus 2024, most notably improvements in GAAP combined ratio and non-GAAP operating ROE, as noted in the "2025 Corporate Performance Results" section above; |

---

---

| | |
|:---|:---|
| ◾ | Grant date value of LTIP award granted in February 2025 was 0.5% higher than his award granted in February 2024; and |

---

---

| | |
|:---|:---|
| ◾ | Total compensation, including salary paid, ACIP payment, and LTIP award, was 6.5% higher in 2025 than 2024. |

---

As CEO, Mr. Marchioni was responsible for all financial, strategic, and investment goals. In making its 2025 compensation decisions for Mr. Marchioni, the CHCC considered our overall corporate performance, as previously detailed in this Compensation Discussion and Analysis under the "2025 Corporate Performance Results" section, and a comprehensive written performance appraisal of the CEO completed by all members of the Board (other than Mr. Marchioni).

Based on the degree of achievement of the Corporate ACIP Measures and the factors noted above in the 2025 Corporate Performance Results, the CHCC determined that Mr. Marchioni's 2025 ACIP payment would be 150% of base salary. This represents a 31.3% increase from his 2024 ACIP as a result of the Company's financial performance, most notably improvements in GAAP combined ratio and non-GAAP operating ROE, as noted in the "2025 Corporate Performance Results" section above, and compares to his initial ACIP opportunity range of 0%-350% of base salary.

The CHCC determined that Mr. Marchioni's ACIP payment was appropriate and consistent with Selective's pay-for-performance philosophy, reinforcing our long-standing history of linking pay and performance.

Our other NEOs were also critical in executing Selective's 2025 strategic goals and delivering key accomplishments. In light of these accomplishments, the CHCC made the following compensation decisions for the other NEOs:

---

| | |
|:---|:---|
| ◾ | Base salary rate increased 1.5% for Mr. Brennan, 2.2% for Mr. Eppers, 1.8% for Ms. Hall, and 0.8% for Mr. Lanza, based on each NEO's performance and ongoing competitiveness with relevant peer benchmarks; |

---

---

| | |
|:---|:---|
| ◾ | The ACIP payments for 2025, compared to the ACIP payments for 2024, increased (i) 15.0% for Mr. Eppers due to the strong investment segment performance and resulting funding under the 2025 Investment Department ACIP, and (ii) 27.4% for Ms. Hall, and 31.1% for Mr. Lanza due to the increase in Corporate ACIP funding, driven by significant improvements in GAAP combined ratio and non-GAAP operating ROE, as noted in the "2025 Corporate Performance Results" section above; |

---

---

| | |
|:---|:---|
| ◾ | The grant date values of LTIP awards granted in February 2025, compared to LTIP awards granted in February 2024, increased 0.9% for Mr. Eppers and 0.9% for Ms. Hall. Mr. Lanza's LTIP award was unchanged; |

---

---

| | |
|:---|:---|
| ◾ | Mr. Brennan participated in the ACIP and LTIP for the first time in 2025, as he did not receive an ACIP payment or annual LTIP award for 2024 given his October 2024 hire date. As previously disclosed and in accordance with the terms of his employment agreement, Mr. Brennan received a $464,000 cash payment (the "2024 Cash Make-Whole and Retention Award")<sup>(1)</sup> and an equity make-whole and retention award, consisting of time-vested restricted stock units having a three-year vesting period ("2024 Equity Make-Whole and Retention Award"), in each case, in part as a make-whole payment for compensation forfeited for leaving his prior employer; and |

---

---

| | |
|:---|:---|
| ◾ | Total compensation, including salary paid, ACIP payments, and LTIP awards, compared to 2024, increased 6.2% for Mr. Eppers, 6.3% for Ms. Hall, and 6.9% for Mr. Lanza. Mr. Brennan's total compensation increased by 49.7%, primarily reflecting a full year of salary in 2025, compared to three months of salary in 2024. |

---

<sup>(1)</sup> $220,000 of the 2024 Cash Make-Whole and Retention Award was paid in 2024 in connection with Mr. Brennan's appointment. The remaining $244,000 of the 2024 Cash Make-Whole and Retention Award was paid following his one-year anniversary of employment with the Company, in accordance with the terms of his employment agreement.

In making 2025 compensation decisions for Messrs. Brennan, Eppers, and Lanza, and Ms. Hall, the CHCC considered the following for each NEO:

Mr. Brennan – Mr. Brennan was appointed Executive Vice President and Chief Financial Officer effective October 1, 2024.

He was responsible for achieving established strategic investment goals and target investment income and returns, while adhering to Selective's investment policies. In recognition of his successful, disciplined portfolio management, Mr. Eppers was named Institutional Investor's 2025 Insurance Company CIO of the Year. Mr. Eppers' significant 2025 contributions were:

◾ Actively managed a diversified, high-quality investment portfolio that supported Selective's capital needs and long-term objectives;

◾ Maintained a stable risk profile while opportunistically adding risk assets during market volatility, exceeding expectations for new money rates, enhancing income resiliency, and deploying investment strategies consistent with Selective's risk tolerance;

This compares to his initial ACIP payment opportunity range of 0%-150% of base salary.

Mr. Eppers' 2025 Investment Department ACIP payment was 15% higher than his 2024 payment, driven by strong performance of the investment segment. This award aligns with our pay-for-performance philosophy, organizational performance, and goal of rewarding and retaining key performers in critical positions.

Ms. Hall – As our former Executive Vice President, Chief Operating Officer, Standard Lines, Ms. Hall had (i) primary responsibility for the overall results of our standard commercial and personal lines segments, (ii) general management responsibility as an executive management team member, and (iii) responsibility for oversight of insurance learning services and distribution strategies. Ms. Hall's significant 2025 contributions were:

Based on the degree of achievement of Corporate ACIP Measures and the factors noted above, the CHCC approved Mr. Marchioni's recommendation that Ms. Hall's 2025 ACIP payment be set at 82% of base salary. This compares to her initial ACIP payment opportunity range of 0%-150% of base salary.

Ms. Hall's 2025 ACIP payment was 27% higher than her 2024 ACIP payment, driven primarily by the Company's financial performance in 2025 versus 2024, resulting from improvements in our GAAP combined ratio and non-GAAP operating ROE, as noted in the "2025 Corporate Performance Results" section above. This award aligns with our pay-for-performance philosophy, organizational performance, and goal of rewarding and retaining key performers in critical positions.

Mr. Lanza – As Executive Vice President, General Counsel and Chief Compliance Officer, Mr. Lanza had (i) primary responsibility for all legal, corporate governance, government affairs, state filings, internal audit, regulatory, compliance matters, and corporate communications, and (ii) general management responsibility as an executive management team member.

Based on the degree of achievement of the Corporate ACIP Measures and the factors noted above, the CHCC approved Mr. Marchioni's recommendation that Mr. Lanza's 2025 ACIP payment be set at 67% of base salary. This compares to his initial ACIP payment opportunity range of 0%-150% of base salary.

Mr. Lanza's 2025 ACIP payment was 31% higher than his 2024 ACIP payment, driven primarily by the Company's financial performance in 2025 versus 2024, resulting from improvements in our GAAP combined ratio and non-GAAP operating ROE, as noted in the "2025 Corporate Performance Results" section above. This award aligns with our pay-for-performance philosophy, organizational performance, and goal of rewarding and retaining key performers in critical positions.

**<u>PERQUISITES</u>**

NEO perquisites in 2025 were limited to tax preparation services and executive physicals and security, which is consistent with prevailing industry practice. We partner with an external security consultant to establish security practices to address security risks to our Chief Executive Officer, based on factors including travel patterns, past security threats, and the evolving security environment. A Company vehicle and driver are provided to our Chief Executive Officer for business travel, in addition to home security arrangements and other security services that were implemented to ensure his physical safety. These services provide the necessary security and enable him to conduct business on behalf of the Company, in line with common industry practices for chief executive officers. See footnote 4 to the Summary Compensation Table for perquisite details.

**<u>EXECUTIVE STOCK OWNERSHIP AND RETENTION REQUIREMENTS</u>**

Selective believes that stock ownership by management encourages the enhancement of stockholder value. Selective's stock ownership guidelines are based on prevailing corporate governance practices and detailed in the Corporate Governance Guidelines.

The following table shows the common stock ownership guidelines for certain officers. Each officer must meet (and subsequently maintain) the current stock ownership guidelines within the later of (i) five years from attainment of the respective officer status, and (ii) three years from any change to these requirements ("Requirement Date"). Base salary increases during the five-year period will require the ultimate ownership requirements to increase when shares are valued on November 1 following such increase.

If, at the November 1 valuation date, an officer fails to meet their current stock ownership requirement as of their Requirement Date, the officer has until March 15 of the following year to cure the non-compliance. If an officer does not cure the non-compliance by March 15, the CHCC may determine to pay all or a portion of such officer's next annual cash incentive plan award in shares of Selective common stock.

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Position** | &nbsp;&nbsp;**Requirement** |
| &nbsp;&nbsp;CEO or President | &nbsp;&nbsp;6 x base salary |
| &nbsp;&nbsp;CFO | &nbsp;&nbsp;4 x base salary |
| &nbsp;&nbsp;Executive Vice Presidents | &nbsp;&nbsp;3 x base salary |
| &nbsp;&nbsp;Senior Vice Presidents or equivalent job grade | &nbsp;&nbsp;1.5 x base salary |

---

In calculating ownership under the guidelines:

---

| | |
|:---|:---|
| ◾ | Shares of Selective common stock of which the officer is deemed to be the "beneficial owner" (as such term is defined under Section 16 of the Exchange Act), seventy-five percent (75%) of the awards of restricted stock or restricted stock units (including related dividend equivalent units) not yet vested, and shares of Selective common stock held in benefit plan investments (i.e., 401(k) plan) are counted; and |

---

◾ Unexercised stock options are not counted.

In addition, officers are required to retain direct ownership of at least 75% of the shares acquired under an equity award granted under any Selective equity compensation plan or other written compensatory arrangements, net of taxes and transaction costs, unless the officer has met their applicable stock ownership requirement. Taxes and transaction costs include: (i) shares retained by Selective to satisfy tax withholding requirements attributable to awards and (ii) shares the officer tenders to pay all or any portion of the exercise price of option grants. All of our officers have met or are on track to meet the required ownership guidelines.

**<u>POLICY ON HEDGING</u>**

Selective seeks to fully align the long-term financial interests of its officers, directors, and employees with the interests of Selective's other stockholders. For this reason, Selective officers, directors, and employees are prohibited from purchasing financial instruments (including prepaid variable forward contracts, equity swaps, collars, and exchange funds), or otherwise engaging in transactions that hedge, offset, or are designed to hedge or offset, any decrease in the market value or the full ownership risks and rewards of their direct or indirect Selective stock holdings.

**<u>RECOUPMENT OF AWARDS</u>**

Effective December 1, 2023, the Board, upon the CHCC's recommendation, adopted a new compensation recoupment policy (the "Clawback Policy") that superseded the prior policy. The Clawback Policy is effective for certain compensation received on or after October 2, 2023, and is consistent with the requirements of the SEC's final compensation clawback rules under the Dodd-Frank Act and the Nasdaq listing standards. It requires recoupment of excess incentive compensation paid to our executive officers if the excess amounts were based on material noncompliance with any financial reporting requirement that causes an accounting restatement, regardless of fraud or misconduct.

**<u>RETIREMENT AND DEFERRED COMPENSATION PLANS</u>**

Selective Insurance Company of America ("SICA"), a wholly owned subsidiary of Selective, employs all our personnel, including the NEOs. We strive to provide a competitive retirement benefits program that enables us to attract and retain talent for the organization. We offer a defined contribution program, including a non-qualified defined contribution deferred compensation plan (the "Deferred Compensation Plan") for certain officers and highly compensated employees, including the NEOs. This program aligns with the benefits offered by many of the companies with which we compete for executive talent.

SICA also has maintained a non-contributory defined benefit pension program consisting of a tax-qualified defined benefit pension plan, the Retirement Income Plan for Selective Insurance Company of America (the "Retirement Income Plan"), and a non-qualified supplemental pension plan for certain executives and employees, first employed on or before December 31, 2005. The accrual of benefits under the pension program ceased as of March 31, 2016. The "Pension Benefits" section of this Proxy Statement provides a more detailed description of the pension program. Because of their earlier hire dates, Messrs. Marchioni and Lanza and Ms. Hall participate in the pension program. Because of their later hire dates, Messrs. Brennan and Eppers are not eligible to participate in the pension program.

SICA offers a tax-qualified defined contribution plan, the Selective Insurance Retirement Savings Plan (the "Retirement Savings Plan"), for employees, including the NEOs, who meet the eligibility requirements. Participants can contribute up to 50% of their eligible compensation to the Retirement Savings Plan, which was up to $23,500 in 2025. Under the Retirement Savings Plan, participant contributions are matched at 100% of the employee's salary deferrals up to 3% of the employee's eligible compensation, and at 50% of the employee's salary deferrals above 3%, up to 6% of the employee's eligible compensation, subject to limitations under the

Code. Participants turning age 50 or older during the year, including all the NEOs, were eligible in 2025 to make additional catch-up salary deferral contributions of up to $7,500 to the Retirement Savings Plan under the Code.

In connection with the curtailment of the Retirement Income Plan, all eligible participants in the Retirement Savings Plan, including the NEOs, began receiving a non-elective contribution of 4% of base salary, after one year of service, to their Retirement Savings Plan accounts, subject to limitations under the Code.

Under the Deferred Compensation Plan, certain executives and employees, including the NEOs, may, subject to certain limitations, defer: (i) up to 50% of their base salary; (ii) up to 100% of their annual bonus (subject to certain limitations to provide for required tax withholding); and/or (iii) all or a percentage of such other compensation as otherwise designated by the administrator of the Deferred Compensation Plan. To compensate for the Code's limitations on SICA's matching contributions for the NEOs under the Retirement Savings Plan, SICA matched our NEOs' contributions to the Deferred Compensation Plan in 2025 as follows: 100% of each NEO's salary deferrals to the Retirement Savings Plan and the Deferred Compensation Plan up to 3% of the employee's base salary, and 50% of the NEO's salary deferrals to the Retirement Savings Plan and the Deferred Compensation Plan above 3%, up to 6% of the NEO's base salary, less any matching contributions to the Retirement Savings Plan. To the extent provisions of the Code and the Retirement Savings Plan limit non-elective contributions to the Retirement Savings Plan, SICA makes non-elective contributions of 4% of base salary to participants' Deferred Compensation Plan accounts. The "Nonqualified Deferred Compensation" section of this Proxy Statement includes additional information about the Deferred Compensation Plan.

SICA also maintains broad-based health and welfare benefit plans in which eligible employees, including the NEOs, participate.

**<u>EMPLOYMENT AGREEMENTS</u>**

SICA has entered into employment agreements with its key executive officers, including the NEOs. Each employment agreement provides for severance in the event of termination: (i) due to death or Disability; (ii) without "Cause"; (iii) due to resignation for "Good Reason" within two years following a "Change in Control" (as each capitalized term is defined in the applicable employment agreement); (iv) due to resignation of the NEO within two years of the Company first imposing a requirement, without the consent of the NEO, that relocates the NEO's business location more than 50 miles; and (v) for the CEO, a resignation at any time for Good Reason. The CHCC believes these agreements are important for the recruitment and retention of key executives, and its Compensation Consultant advised that the terms of the employment agreements, when executed, were market-competitive within our peer group. Furthermore, after or in connection with a change in control, uncertainty may arise among our key executives regarding their continued employment, possibly leading to their distraction or departure. The purpose of the employment agreements is to retain our key executives and reinforce and encourage their continued attention and dedication during the potentially critical period of a change in control.

The change in control provisions of the NEOs' employment agreements concerning severance payments, outstanding awards under our stock and cash plans, and continued insurance coverages or coverage reimbursement, are triggered following the NEO's employment termination without Cause or the resignation of the NEO for Good Reason within two years following a change in control. This double trigger ensures that such a payout does not automatically occur upon a change in control only.

The employment agreements are described in the section entitled "Employment Agreements and Potential Payments upon Termination or Change in Control" of this Proxy Statement. This section includes information on multipliers used to calculate the severance payment and duration of reimbursement for the cost of certain benefit coverages provided to individual executives upon termination. We believe these multipliers are consistent with each NEO's level and value of position to the organization. SICA's current employment agreements do not contain excise tax gross-up provisions.

**<u>TAX TREATMENT AND ACCOUNTING</u>**

Code Section 162(m) generally disallows a federal income tax deduction to public companies for annual compensation over $1 million (per individual) paid to their chief executive officer, chief financial officer, and certain other NEOs. In considering the goals of our executive compensation program in making its compensation decisions, the CHCC retains the flexibility to award compensation it believes to be in Selective's best long-term interests, even if the awards may not be fully deductible under Code Section 162(m).

GAAP requires compensation expense to be measured on the income statement for all stock-based payments at the grant date fair value for equity instruments (including restricted stock unit awards) and at market value on the date of vesting for liability instruments (including cash incentive unit awards). The CHCC has considered the impact of GAAP on our use of stock-based compensation as a retention tool. The CHCC has determined that the current estimated costs of using stock-based compensation relative to the benefits they provide are appropriate and do not warrant any change to our current incentive framework.

We have designed our executive compensation programs and awards to be exempt from or, where applicable, comply with the provisions of Section 409A of the Code. For example, if the executives are "specified employees" under Section 409A of the Code, any payments of deferred compensation under our nonqualified deferred compensation plans that are triggered by the executive officer's separation from service are not payable before the first day of the seventh month after the executive's date of separation from service.

**COMPENSATION COMMITTEE REPORT**

The Compensation and Human Capital Committee establishes general executive compensation policies and establishes the salaries and bonuses of Selective's named executive officers, including the Chief Executive Officer. The Compensation and Human Capital Committee (i) has reviewed and discussed the Compensation Discussion and Analysis with management, and (ii) based on this review and discussion, recommended to the Board, and the Board approved, the inclusion of the Compensation Discussion and Analysis in this Proxy Statement.

Submitted by the Compensation and Human Capital Committee of the Board,

Stephen C. Mills, Chairperson Cynthia S. Nicholson <br> Ainar D. Aijala, Jr. Julie Parsons <br> Lisa Rojas Bacus

The Compensation Committee Report does not constitute soliciting material, and it shall not be deemed to be filed or incorporated by reference into any other Selective filing under the Securities Act of 1933, as amended ("Securities Act"), or the Exchange Act, except to the extent that Selective specifically incorporates the Compensation Committee Report by reference therein.

**POLICIES AND PRACTICES RELATED TO THE GRANT OF CERTAIN EQUITY AWARDS CLOSE IN TIME TO THE RELEASE OF MATERIAL NON-PUBLIC INFORMATION**

In response to Item 402(x)(1) of Regulation S-K, Selective does not currently grant new awards of stock options, stock appreciation rights, or similar option-like instruments. Selective, however, maintains a Policy on Granting Equity and Cash Incentive Unit Awards specifying that Selective will grant LTIP awards, other than new hire awards and interim promotion and retention awards, at a meeting of the CHCC held following the release of the Company's fourth quarter and year-end earnings results. Under the policy, LTIP awards to Section 16 "officers" must be approved by the CHCC at a meeting or by unanimous written consent. The grant date of any LTIP award approved at a meeting, or by unanimous consent, of the CHCC will be the date of such meeting or unanimous written consent.

**SUMMARY COMPENSATION TABLE**

The following Summary Compensation Table reflects the compensation earned by or paid to the NEOs during 2025, 2024, and 2023.

<sup>(1)</sup> This column reflects the aggregate grant date fair value of the 2025, 2024, and 2023 grants of performance-based restricted stock unit awards and 2025, 2024, and 2023 grants of performance-based cash incentive unit awards and, for Mr. Brennan, the grant date fair value of his 2024 Equity Make-Whole and Retention Award. The grants of performance-based restricted stock units generally vest three years from the date of grant, conditioned on the attainment of certain pre-determined performance goals. Grants of performance-based cash incentive unit awards generally vest at the payment date, which is as soon as practicable in the calendar year following the end of the calendar year coincident with the end of the three-year performance period. The value of each cash incentive unit initially awarded increases or decreases to reflect the TSR on Selective common stock over the three-year performance period for the award. For the 2025, 2024, and 2023 performance-based cash incentive unit awards, the number of cash incentive units ultimately earned increases or decreases based on (i) cumulative three-year statutory NPW growth relative to the Cash Incentive Unit Peer Group, and (ii) cumulative three-year statutory operating return on policyholder surplus relative to the Cash Incentive Unit Peer Group. Restricted stock unit and cash incentive unit awards are generally subject to forfeiture should the grantee resign or be terminated for cause prior to vesting. However, restricted stock unit and cash incentive unit awards granted to Messrs. Marchioni, Eppers, and Lanza and Ms. Hall will vest upon attainment of the performance condition only, as they have attained their early retirement ages.

The grant date fair values for the performance-based restricted stock unit and performance-based cash incentive unit awards granted to the NEOs are as follows:

The aggregate grant date fair value reported in this column assumes the following: (i) the predetermined performance goals for the restricted stock unit grants are probable of being attained; (ii) initial per unit values for the cash incentive unit awards of $100; and (iii) a 100% peer group unit multiplier for cash incentive unit awards. For further discussion of the fair value calculation of the awards in this column, please refer to Note 16. "Share-Based Payments" to the consolidated financial statements in our 2025 Annual Report. The maximum value assuming the highest level of performance conditions for the performance-based restricted stock units are consistent with the amounts above. Although the maximum number of performance-based cash incentive units potentially issuable is 150% of the original grant for the 2023, 2024, and 2025 grants, the ultimate maximum value of the 2023, 2024, and 2025 grants cannot be determined at this time because the initial value of each unit is adjusted based on the TSR of Selective common stock over the grant's three-year performance period. Mr. Brennan was not granted performance-based restricted stock unit or performance-based cash incentive unit awards in 2024, as he received the 2024 Equity Make-Whole and Retention Award.

<sup>(2)</sup> Amounts in this column are ACIP awards to the NEOs earned in 2025 and paid in 2026, earned in 2024 and paid in 2025 (except for Mr. Brennan), and earned in 2023 and paid in 2024. These awards were granted under the Cash Incentive Plan. Mr. Brennan did not receive an ACIP payment for 2024; instead, he received the 2024 Make-Whole ACIP Payment given his date of hire in October 2024.

<sup>(3)</sup> Amounts in this column reflect the actuarial increase in the present value of each NEO's pension benefits under all defined benefit pension plans of SICA, determined using the same interest rate and mortality assumptions as those used for financial statement reporting purposes. There were no changes to the benefit formulas under the defined pension benefit plans in 2025, as the plans were amended to cease further accruals effective as of March 31, 2016. The changes in pension values reported in this column are primarily attributable to a decrease in the discount rate used to calculate present value and the use of the most-recently released mortality tables. Based on Messrs. Brennan's and Eppers' hire dates, they are not eligible to participate in SICA's defined benefit pension plans. There were no above-market or preferential earnings on deferred compensation under SICA's nonqualified deferred compensation program.

<sup>(4)</sup> For 2025, amounts in this column for each NEO reflect the following, which are based on actual incremental Company costs of providing these items to the NEOs (amounts in this footnote may not exactly match the figures in the Summary Compensation Table due to rounding):

---

<sup>(1)</sup> Amounts represent minimum and maximum potential ACIP awards under the Cash Incentive Plan for 2025 based on 2025 base salary rates. Maximum awards reflect the maximum ACIP award established by the CHCC. Actual payouts of the above-referenced awards are included in the Non-Equity Incentive Plan Compensation column of the Summary Compensation Table. For information regarding the ACIP, see the section of the Compensation Discussion and Analysis entitled, "Annual Cash Incentive Program."

<sup>(2)</sup> Performance-based cash incentive unit awards were granted under the Cash Incentive Plan, and performance-based restricted stock unit awards were granted under the Omnibus Stock Plan. For a description of the material terms of such awards, see the section of the Compensation Discussion and Analysis entitled, "Elements of Long-Term Compensation."

<sup>(3)</sup> The number of performance-based cash incentive units paid can range from 0%-150%, and therefore, the amount payable could be $0. The threshold selected represents performance compared to the 30<sup>th</sup> percentile of the Cash Incentive Unit Peer Group, the target represents performance compared to the 50<sup>th</sup> percentile of the Cash Incentive Unit Peer Group, and the maximum represents performance greater than or equal to the 80<sup>th</sup> percentile of the Cash Incentive Unit Peer Group.

<sup>(4)</sup> The grant date fair value reported in this column assumes the following: (i) the pre-determined performance goals for the restricted stock unit grants are probable of being attained; (ii) initial per unit values for the cash incentive unit awards of $100; and (iii) a 100% peer group unit multiplier for cash incentive unit awards. For further discussion of the fair value calculation of the awards in this column, please refer to Note 16. "Share-Based Payments" to the consolidated financial statements in our 2025 Annual Report.

**PENSION BENEFITS**

SICA maintains a tax-qualified, non-contributory defined benefit pension plan, the Retirement Income Plan. Many SICA employees, including Mr. Marchioni, Ms. Hall, and Mr. Lanza, and certain former employees whose employment commenced on or before December 31, 2005, are eligible to receive benefits under the Retirement Income Plan. SICA also maintains the unfunded Selective Insurance Supplemental Pension Plan ("SERP") to provide supplemental benefits to certain executives and other participants in the Retirement Income Plan equal to the difference between: (i) the benefits payable to these participants under the Retirement Income Plan, calculated without regard to Code limitations on annual amounts payable under the Retirement Income Plan; and (ii) the actual benefits payable to these participants under the Retirement Income Plan.

Benefits under the Retirement Income Plan and SERP were curtailed in the first quarter of 2013, when both plans were amended to cease accrual of additional benefits for all participants as of March 31, 2016. Participants as of March 31, 2016, remain entitled to the benefits already earned but have not earned additional benefits since that date.

The Retirement Income Plan was amended as of July 1, 2002, to provide for different calculations based on age and company service as of that date. Monthly benefits payable at normal retirement age under the Retirement Income Plan and the SERP for the NEOs are computed as follows. Defined terms used in this section, but not defined in this Proxy Statement, have the meanings given to them in the Retirement Income Plan.

1. If a participant: (i) completed at least five years of Vesting Service on or before July 1, 2002; and (ii) the sum
of a participant's age and Vesting Service is 55 or more on or before July 1, 2002, a participant's benefit is equal
to the sum of: (a) 2% of Average Monthly Compensation (base salary), less 1 3/7% of Primary Social Security benefit multiplied by
the number of years of Benefit Service through June 30, 2002 (up to 35 years) reduced by the monthly amount, if any, of retirement
annuity payable under the group annuity contract issued by AXA Equitable Life Insurance Company that was purchased under a prior terminated
defined benefit pension plan, based on Benefit Service as of June 30, 2002, but including compensation earned after such date; and
(b) 1.2% of Average Monthly Compensation multiplied by the number of years of Benefit Service after June 30, 2002.

2. If a participant first became eligible for the plan before July 1, 2002, but did not qualify for 1 above, the participant's
benefit is equal to the greater of: (i) the benefit accrued as of June 30, 2002 equal to 2% of Average Monthly Compensation
less 1 3/7% of Primary Social Security Benefit multiplied by years of Benefit Service reduced by the monthly amount, if any, of retirement
annuity payable under the group annuity contract issued by AXA Equitable Life Insurance Company that was purchased under a prior terminated
defined benefit pension plan, based on Benefit Service as of June 30, 2002, but including compensation earned after such date for
purposes of determining the participant's Average Monthly compensation; and (ii) 1.2% of Average Monthly Compensation multiplied
by years of Benefit Service.

3. If a participant first became a participant in the plan after July 1, 2002, the benefit is equal to 1.2% of Average Monthly Compensation
multiplied by years of Benefit Service.

The earliest retirement age is 55 with 10 years of service or the attainment of 70 points (age plus years of service). If a participant chooses to begin receiving benefits before their 65th birthday, the amount of the monthly benefit will be reduced as follows:

◾ By 1/180th for each complete calendar month for the first 60 months by which the first early retirement benefit payment precedes the attainment of Normal Retirement Age (age 65);

◾ By 1/360th for each complete calendar month for the next 60 months by which the first early retirement benefit payments precede Normal Retirement Age; and

---

| | |
|:---|:---|
| ◾ | By 40% plus 1/600th per month for each month before age 55. |

---

At retirement, participants receive monthly pension payments. There are four optional forms of payments that can be chosen as alternatives to the normal form of payment, which for a married participant is an automatic 50% joint and surviving spouse annuity, and for an unmarried participant is a single life annuity.

The following table shows information regarding the pension benefits of our NEOs. Based on Mr. Brennan's hire date of October 1, 2024, and Mr. Eppers' hire date of March 2, 2015, they are not eligible to participate in the Retirement Income Plan or the SERP:

<sup>(1)</sup> Messrs. Marchioni and Lanza and Ms. Hall have attained their early retirement ages under the terms of the Retirement Income Plan and the SERP.

<sup>(2)</sup> The Retirement Income Plan imposes a one-year waiting period for plan participation, which year is not included in years of credited service.

<sup>(3)</sup> Present value as of December 31, 2025, is calculated based on Normal Retirement Age of 65 using a 5.48% discount rate. For further discussion, see Note 15. "Retirement Plans" to the consolidated financial statements in our 2025 Annual Report.

**NONQUALIFIED DEFERRED COMPENSATION**

The Deferred Compensation Plan allows participants to defer receipt of up to 50% of base salary and up to 100% of their annual bonus (subject to certain limitations to provide for required tax withholding). Participant accounts are credited with a notional rate of return (positive or negative) based on the performance of investment options selected by the participants from a menu of notional investment options. Participants can elect to schedule in-service withdrawals or withdrawals upon separation from service.

SICA makes matching contributions to a participant's Deferred Compensation Plan account to supplement matching contributions under the Retirement Savings Plan. For 2025, such matching contributions consisted of 100% of the first 3% of base salary and 50% of the next 3% of base salary deferred to the Retirement Savings Plan and the Deferred Compensation Plan together, minus any matching contribution made to a participant's Retirement Savings Plan account. Effective January 1, 2010, the Deferred Compensation Plan was amended for participants ineligible to participate in the Retirement Income Plan to provide a non-elective contribution to the extent not made to a participant's Retirement Savings Plan account due to limitations under the Code and the Retirement Savings Plan. The non-elective contribution to the Deferred Compensation Plan is equal to 4% of a participant's base salary, minus any non-elective contribution made to the Retirement Savings Plan. In conjunction with the amendment of the Retirement Income Plan and the SERP to cease accrual of further benefits under those plans effective as of March 31, 2016, all participants affected by the curtailment, including the NEOs, became eligible for the non-elective contribution effected on April 5, 2013.

The following table shows information regarding nonqualified deferred compensation of our NEOs:

<sup>(2)</sup> This column includes the value of earned and unearned performance-based restricted stock units granted under the Omnibus Stock Plan and any related accrued DEUs. These performance-based awards would normally vest upon: (i) achievement of early or normal retirement eligibility or continuation in service through the end of the applicable performance period; and (ii) the achievement of the specified performance goals applicable to each such award and be payable following the end of the applicable three-year performance period. As each of Messrs. Marchioni, Eppers, and Lanza and Ms. Hall have attained their early retirement ages, their respective restricted stock unit awards have vested, but their ultimate payment value will only be determined upon achievement of each award's applicable performance condition. This column also includes the value of performance-based cash incentive units awarded under the Cash Incentive Plan to the NEOs. The value of such awards is calculated using: (i) the target 100% unit multiplier for the number of cash incentive units granted; and (ii) the per unit value at December 31, 2025. Under the Cash Incentive Plan, the NEOs' awards would fully vest upon achievement of early or normal retirement eligibility or continuation in service through the end of the payment date and be payable following the end of the applicable three-year performance period. As Messrs. Marchioni, Eppers, and Lanza and Ms. Hall have attained their early retirement ages, their respective cash incentive unit awards have vested, but their ultimate payment value will only be determined upon achievement of each award's applicable performance conditions.

<sup>(3)</sup> This column includes the value of unvested performance-based restricted stock units granted under the Omnibus Stock Plan and any related accrued DEUs. In the event of total disability, these performance-based awards would normally vest for all the NEOs upon the achievement of the specified performance goals applicable to each such award and be payable following the end of the applicable three-year performance period. In the event of death, these performance-based awards are immediately vested and payable for all the NEOs. This column also includes the value of performance-based cash incentive units awarded under the Cash Incentive Plan to the NEOs. The value of such awards is calculated using: (i) the target 100% unit multiplier for the number of cash incentive units granted; and (ii) the per unit value at December 31, 2025. Under the Cash Incentive Plan, in the event of death or total disability, the NEOs' awards would fully vest and be payable following the end of the applicable three-year performance period. This column also includes the cash severance payment provided for in each NEO's Employment Agreement.

<sup>(4)</sup> This column includes the value of unvested performance-based restricted stock units granted under the Omnibus Stock Plan and any related accrued DEUs.

This column also includes the cash severance payment and the value of applicable medical, dental, and vision coverages, as provided for in each respective NEO's Employment Agreement.

<sup>(5)</sup> This column includes the value of unvested performance-based restricted stock units granted under the Omnibus Stock Plan, and any related accrued DEUs, which would immediately vest and be payable upon a termination of employment within two years following a change in control. This column also includes the value of performance-based cash incentive units awarded under the Cash Incentive Plan to the NEOs, all of which would vest upon a termination of employment within two years following a change in control. The value of such awards is calculated using: (i) a 150% per unit multiplier; and (ii) the per unit value at December 31, 2025. This column also includes the cash severance payment and the value of applicable medical, dental, and vision coverages, as provided for in each NEO's Employment Agreement.

<sup>(6)</sup> Ms. Hall retired on January 5, 2026, and is therefore no longer eligible for any such payments.

**CEO PAY RATIO**

Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act") and Item 402(u) of Regulation S-K requires us to provide the ratio of the annual total compensation of our CEO, Mr. Marchioni, to that of our median employee. The assumptions, estimates, and methodologies that we used for this pay ratio disclosure may differ from those used by other companies. As a result, the following information may not be directly comparable to the information provided by other companies in our peer group or otherwise. The pay ratio included in this information is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K.

SEC rules require us to identify a new median employee at least once every three years. During 2025 and 2024, there were no changes to our employee population or our employee compensation arrangements that we believed would significantly impact our pay ratio disclosure, however our previous median employee departed the organization. Accordingly, a new median employee was determined for 2025. We identified the median employee by tabulating 2025 W-2 Medicare Wages on December 31, 2025. In our analysis, we included all employees employed by us on December 31, 2025, whether employed full-time, part-time, or seasonally, excluding the CEO. We did not make any adjustments or annualize compensation for employees we did not employ for all of 2025. We believe using W-2 Medicare Wages is a consistent and straightforward methodology that we can easily replicate in future years. This methodology is consistent with our approach for identifying the previous median employee.

Mr. Marchioni's 2025 total compensation was $6,848,121 (reflected in the Summary Compensation Table), and our median employee's 2025 total compensation was $118,344. Mr. Marchioni's 2025 total compensation was approximately 58 times that of our median employee.

**PAY VERSUS PERFORMANCE**

The table below discloses "Compensation Actually Paid" ("CAP"), calculated under SEC rules, for (i) Selective's principal executive officer ("PEO") and (ii) Selective's NEOs other than the PEO, on an average basis, as well as certain financial performance measures for Selective for the past five fiscal years. Consistent with SEC rules, Selective has identified GAAP combined ratio as its "Company-Selected Measure," an accepted insurance industry standard of profitability. Selective believes this measure is the most important financial performance measure used to link CAP to company performance. GAAP combined ratio is a key component of Selective's compensation program, as described in our Compensation Discussion and Analysis section above.

<sup>(1)</sup> The dollar amounts reported in column (b) are the amounts of total compensation reported for the Company's PEO for each corresponding fiscal year in the "Total" column of the SCT. Mr. Marchioni served as PEO during 2025, 2024, 2023, 2022, and 2021.

<sup>(2)</sup> Consistent with SEC rules, we made the following adjustments to the SCT totals for NEOs to calculate CAP amounts:

---

| | |
|:---|:---|
| ◾ | Deducted the actuarial increase in the present value of each applicable NEO's pension benefits under SICA's defined benefit pension plans, which represented changes in pension values primarily attributable to an increase in the discount rate used to calculate present value and the use of the most-recently released mortality tables. See tables below for quantitative detail for the PEO and non-PEO NEOs. |

---

---

| | |
|:---|:---|
| ◾ | Added changes in pension values attributable to current years' service and any change in pension value attributable to plan amendments made during each fiscal year. Our pension plan is closed to new entrants and existing participants ceased accruing benefits after March 31, 2016. There were no amendments to the pension plan in each fiscal year that changed pension values. |

---

◾ Deducted the grant date fair values for the performance-based restricted stock unit ("RSU") and performance-based cash incentive unit ("CIU") awards granted to the NEOs. See tables below for quantitative detail for the PEO and non-PEO NEOs.

◾ Added the fair values of performance-based RSU (and related accrued dividend equivalent units) and performance-based CIU awards granted to the NEOs in each year, valued as of each fiscal year end. See tables below for quantitative detail for the PEO and non-PEO NEOs.

---

| | |
|:---|:---|
| ◾ | Added the year-over-year change in fair value of the prior years' unvested performance-based RSU (and related accrued dividend equivalent units) and performance-based CIU awards, and the awards that vested during each fiscal year. See tables below for quantitative detail for the PEO and non-PEO NEOs. |

---

Additionally, assumptions made in the valuation of the 2025, 2024, 2023, 2022, and 2021 grants of performance-based RSU awards, and the 2025, 2024, 2023, 2022, and 2021 grants of performance-based CIU awards that differ materially from those disclosed as of the grant date of such awards include adjustment of:

---

| | |
|:---|:---|
| ◾ | Selective's common stock price per share and reinvested dividends to reflect the measurement date value (instead of the common stock price per share and reinvested dividends at grant date). Measurement date represents each fiscal year end or the date of vesting for those awards that vested in each fiscal year. |

---

---

| | |
|:---|:---|
| ◾ | Per unit values for the performance-based CIU awards for the TSR value at the measurement date (instead of using the initial per unit value of $100). |

---

---

| | |
|:---|:---|
| ◾ | The peer group multiplier for CIU awards to reflect the Monte Carlo valuation received at the measurement date, recorded on a one-quarter lag (instead of using the initial peer group multiplier of 100%). |

<sup>(6)</sup> We used our peer group for purposes of Item 201(e) of Regulation S-K to calculate peer group total shareholder return. The peer group used for this purpose is the group of all Nasdaq-listed companies with SIC Code 6330-6339, "Fire, Marine, and Casualty Insurance." TSR for both the Company and the peer group is based on an initial $100 investment, measured on a cumulative basis from the market close on December 31, 2020, through and including the end of the applicable fiscal year as presented in the table.

**<u>Narrative Discussion of</u>** **<u>Relationship between CAP and Performance Measures</u>**

We believe that the Pay Versus Performance Table reflects alignment of CAP and Selective's performance of key financial performance measures. The information in the charts below further demonstrates a general correlation among the CAP amounts set forth in columns (c) and (e) and Selective's TSR, net income, and GAAP combined ratio.

In addition to reviewing this discussion and the Pay Versus Performance Table above, we encourage you to read the Compensation Discussion and Analysis section of this Proxy Statement, which explains our executive compensation philosophy and programs, and compensation decisions relating to 2025 compensation for our NEOs.

<u>CAP versus Selective TSR</u>

![](tm261551d2_def14a-img020.jpg)

In each of 2023, 2022, and 2021, Selective's TSR was positive and markedly outperformed the Peer Group TSR. However, in 2024 and in 2025, Selective's TSR was negative and trailed the Peer Group TSR. From 2021 to 2022, CAP to PEO and Average CAP to Non-PEO NEOs decreased, while Selective's TSR increased. From 2022 to 2023, CAP to PEO increased as TSR also increased, but Average CAP to Non-PEO NEOs decreased primarily due to Mr. Wilcox's departure-related forfeiture in 2023 of outstanding long-term incentive compensation awards. From 2023 to 2024, CAP to PEO decreased, as did TSR. Average CAP to Non-PEO NEOs was higher in 2024 compared to 2023, primarily because the 2023 Average CAP to Non-PEO NEOs reflected Mr. Wilcox's forfeiture of outstanding long-term incentive compensation awards referenced above. From 2024 to 2025, TSR decreased. During this period, CAP to PEO and Average CAP to Non-PEO NEOs increased, primarily due to increases in ACIP bonus payments reflecting significant improvements in key annual financial results, including GAAP combined ratio and net income, as shown in the graphs below.

<u>CAP versus Selective Net Income</u>

![](tm261551d2_def14a-img021.jpg)

The relationship between CAP to PEO and Average CAP to Non-PEO NEOs to Selective's net income was reasonably correlated for 2021 through 2025. CAP to PEO and Average CAP to Non-PEO NEOs decreased as net income decreased from 2021 to 2022. From 2022 to 2023, CAP to PEO increased as net income increased, but Average CAP to Non-PEO NEOs decreased primarily due to Mr. Wilcox's departure-related forfeiture in 2023 of outstanding long-term incentive compensation awards. From 2023 to 2024, CAP to PEO decreased, as did net income. Average CAP to Non-PEO NEOs was higher in 2024 compared to 2023, primarily because the 2023 Average CAP to Non-PEO NEOs reflected Mr. Wilcox's forfeiture of outstanding long-term incentive compensation awards referenced above. From 2024 to 2025, CAP to PEO and Average CAP to Non-PEO NEOs

each increased as net income also increased, reflecting alignment between increases in ACIP bonus payments and significant improvements in key annual financial results, including GAAP combined ratio and net income.

<u>CAP versus Selective GAAP Combined Ratio</u>

![](tm261551d2_def14a-img022.jpg)

For each of 2025, 2023, 2022, and 2021, Selective generated strong GAAP combined ratio results. However, for 2024, the GAAP combined ratio was adversely impacted primarily by unfavorable prior year casualty reserve development. The relationship between CAP to PEO and Average CAP to Non-PEO NEOs to Selective's GAAP combined ratio for 2021 through 2025 was reasonably correlated. CAP to PEO and Average CAP to Non-PEO NEOs decreased from 2021 to 2022 as the GAAP combined ratio weakened. From 2022 to 2023, CAP to PEO increased modestly due to stock price appreciation as the GAAP combined ratio weakened marginally, while the Average CAP to Non-PEO NEOs decreased, in part due to Mr. Wilcox's departure-related forfeiture in 2023 of outstanding long-term incentive compensation awards. From 2023 to 2024, CAP to PEO decreased as the combined ratio weakened. Average CAP to Non-PEO NEOs was higher in 2024 compared to 2023, primarily because the 2023 Average CAP to Non-PEO NEOs reflected Mr. Wilcox's forfeiture of outstanding long-term incentive compensation awards referenced above. From 2024 to 2025, CAP to PEO and Average CAP to Non-PEO NEOs each increased as GAAP combined ratio improved, reflecting alignment between increases in ACIP bonus payments and significant improvements in key annual financial results, including GAAP combined ratio and net income.

**Important Financial Performance Measures**

The following unranked tabular list sets forth the most important performance measures used by Selective to link CAP for all NEOs to company performance for 2025:

---

| |
|:---|
| &nbsp;&nbsp;GAAP Combined Ratio |
| &nbsp;&nbsp;Cumulative non-GAAP operating ROE<sup>\*</sup> / cumulative statutory operating return on policyholders' surplus |
| &nbsp;&nbsp;Cumulative policy count growth |
| &nbsp;&nbsp;Cumulative statutory net premiums written growth |
| &nbsp;&nbsp;Profitability improvement |
| &nbsp;&nbsp;Expense management and operational efficiency |
| &nbsp;&nbsp;Customer experience |

\* See the Compensation Discussion and Analysis section of this Proxy Statement for a discussion of non-GAAP operating ROE, which is a non-GAAP performance measure.

**DIRECTOR COMPENSATION**

We compensate non-employee directors for their Board service with a combination of cash and equity in amounts commensurate with their role and involvement, and consistent with peer company practices. In setting director compensation, we consider the significant time and effort our directors expend in fulfilling their duties, and the skill level required of our Board members. We intend to compensate our non-employee directors competitively to attract and retain high-caliber directors and align their interests with those of our stockholders. Mr. Marchioni, our CEO, did not receive additional compensation for his service as a director in 2025.

The CHCC, which is comprised solely of independent directors, has the primary responsibility for reviewing and approving compensation for non-employee directors, including the following elements: retainer; meeting fees; committee member fees; committee chairperson fees; lead independent director fee; and equity compensation. In October 2024, the CHCC reviewed the form and amount of compensation paid to our non-employee directors for their Board service for 2025. The CHCC considered the results of an independent analysis conducted by the Compensation Consultant, who reviewed non-employee director compensation trends and data from companies comprising the Proxy Peer Group that the CHCC uses in its review of executive compensation. After consulting with the Compensation Consultant, and in light of peer data, the CHCC approved the following changes to Selective's non-employee director compensation program (in each case, effective as of January 1, 2025): (i) increased the Annual Retainer Fee from $100,000 to $105,000; (ii) increased the Grant Date Fair Value of Annual Equity Award from $110,000 to $125,000; and (iii) increased the Annual Lead Independent Director Fee from $40,000 to $50,000.

The following table summarizes the types and amounts of compensation paid to our non-employee directors in 2025:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Type of Compensation | <u>Amount</u> ($) |
| &nbsp;&nbsp;Annual Retainer Fee | 105000 |
| &nbsp;&nbsp;Grant Date Fair Value of Annual Equity Award | 125000 |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Finance and Investments Committee | 35000 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Risk Committee | 25000 |
| &nbsp;&nbsp;Lead Independent Director Fee | 50000 |
| &nbsp;&nbsp;Expenses | Reasonable |

---

\* Directors do not receive annual committee member retainer fees for service on two standing committees. Any Director who serves on a third Board committee will be paid an annual retainer for that committee service. Non-standing committees and the Executive Committee have no annual committee member retainer fees or annual chairperson fees unless otherwise determined by the CHCC.

\*\* A Director who receives an annual chairperson fee for a committee does not also receive an annual committee member retainer fee for such committee.

As the table above shows, in 2025, the non-employee directors received compensation in the forms of cash and equity (consisting of restricted stock units) for their director service. The CHCC annually reviews and approves the compensation for non-employee directors, including the Annual Retainer Fee. For 2025, non-employee directors had the election to receive up to 100% of their Annual Retainer Fee in shares of Selective common stock. Any remaining balance of the Annual Retainer Fee was paid in cash. Non-employee directors made this election before December 31, 2024. The Annual Retainer Fee was paid in one installment on the second business day following Selective's 2025 Annual Meeting of Stockholders.

For 2025, the annual equity grant under Selective's non-employee director compensation program was made entirely in restricted stock units granted under the Company's 2024 Omnibus Stock Plan. Shares of Selective common stock paid to directors as a portion of their Annual Retainer Fee were issued under the Company's 2024 Omnibus Stock Plan. Annual Committee Member Fees, Annual Committee Chairperson Fees, and the Lead Independent Director Fee were paid in cash as reflected in the table above.

The following table shows compensation earned by or paid to our non-employee directors during 2025 for 2025 service:

\* No directors held any outstanding stock options as of December 31, 2025.

***<u>Director Stock Ownership and Retention Requirements</u>***

Selective believes that stock ownership by directors encourages the enhancement of stockholder value. Selective's stock ownership guidelines, based on prevailing corporate governance practices, are detailed in the Corporate Governance Guidelines.

Each non-employee director must own five times the amount of their annual retainer within five years of their first election to the Board. The following count toward satisfying the guidelines: (i) shares of Selective common stock of which the director is deemed to be the "beneficial owner" (as such term is defined under Section 16 of the Exchange Act); (ii) awards of restricted stock and restricted stock units (including related dividend equivalent units) not yet vested; (iii) shares of Selective common stock held in benefit plan investments (i.e., 401(k) Plan); and (iv) deferred shares of Selective common stock held in accounts of directors. Unexercised stock options are not counted. All our directors have met, or are on track to meet, the required ownership guidelines.

**INFORMATION ABOUT PROPOSAL 2**

The Dodd-Frank Act requires our Board to provide Selective's stockholders the opportunity to vote annually to approve, on an advisory (non-binding) basis, the compensation of our named executive officers disclosed according to the SEC's compensation disclosure rules (also referred to as say-on-pay). Although the vote is non-binding, the Board and the CHCC value our stockholders' opinions and will consider the outcome of this vote when making future compensation decisions for named executive officers. In 2025, our stockholders overwhelmingly supported our compensation decisions, with over 97% of votes cast voting in favor of our say-on-pay proposal.

We urge stockholders to read the Compensation Discussion and Analysis section of this Proxy Statement, which discusses our compensation philosophy, policies, and procedures. The following resolution is being submitted to stockholders for approval at the Annual Meeting pursuant to Section 14A of the Exchange Act:

**"RESOLVED, that the stockholders of Selective Insurance Group, Inc. ("Selective") approve, on an advisory basis, the 2025 compensation of Selective's named executive officers as such compensation is disclosed in this Proxy Statement pursuant to Item 402 of Regulation S-K or any successor thereto."**

If a majority of stockholders vote against this proposal, neither the Board nor the CHCC will be required to take any specific action because this vote is non-binding and advisory. Nonetheless, consistent with our record of stockholder responsiveness, the CHCC will consider our stockholders' concerns and take them into account in future determinations concerning our executive compensation programs. The Board recommends you indicate your support for the compensation of our named executive officers as outlined in the above resolution.

Unless the Board modifies its policy on the frequency of holding say-on-pay votes, the next say-on-pay advisory vote will be held at our 2027 Annual Meeting of Stockholders. The next vote on the proposal regarding the frequency of the say-on-pay advisory vote (also referred to as "say-on-frequency") is expected to occur at the 2029 Annual Meeting of Stockholders.

***<u>Board Recommendation</u>***

THE BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE "**FOR**" THE ADVISORY RESOLUTION APPROVING THE 2025 COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT.

**INFORMATION ABOUT PROPOSAL 3**

**Ratification of Appointment of Independent Registered Public Accounting Firm**

The Audit Committee has appointed KPMG LLP to act as Selective's independent registered public accounting firm for the fiscal year ending December 31, 2026. The Audit Committee monitors the independence of the independent registered public accounting firm and compliance with auditor partner rotation requirements. On the Audit Committee's recommendation, the Board has approved the appointment and has directed that the appointment be submitted to Selective's stockholders for ratification at the Annual Meeting.

Stockholder ratification of the appointment of KPMG LLP as Selective's independent registered public accounting firm is not required. The Board, however, is submitting the appointment to our stockholders for ratification as a good corporate governance practice. If our stockholders do not ratify the appointment, the Audit Committee and the Board will reconsider whether to retain KPMG LLP or another firm, but they are under no obligation to engage a different auditing firm. Even if our stockholders ratify the appointment, the Audit Committee and the Board may direct the appointment of a different auditing firm at any time during the 2026 fiscal year if the Audit Committee and the Board determine that such a change would be in the best interests of Selective and our stockholders.

A representative of KPMG LLP will attend virtually and participate in the Annual Meeting. The representative will have an opportunity to make a statement and be available to respond to appropriate questions.

***<u>Board Recommendation</u>***

THE BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS 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.

**FEES OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

KPMG LLP, Selective's independent registered public accounting firm, provided services in the following categories and amounts in 2025 and 2024:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**Category** | &nbsp;&nbsp;**2025** | &nbsp;&nbsp;**2024** |
| &nbsp;&nbsp;Audit Fees<sup>(1)</sup> | &nbsp;&nbsp;$2385000 | &nbsp;&nbsp;$2195000 |
| &nbsp;&nbsp;Audit-Related Fees | &nbsp;&nbsp;$0 | &nbsp;&nbsp;$0 |
| &nbsp;&nbsp;Tax Fees<sup>(2)</sup> | &nbsp;&nbsp;$3493 | &nbsp;&nbsp;$0 |
| &nbsp;&nbsp;All Other Fees<sup>(3)</sup> | &nbsp;&nbsp;$119500 | &nbsp;&nbsp;$115000 |
| &nbsp;&nbsp;**TOTAL** | &nbsp;&nbsp;$2507993 | &nbsp;&nbsp;$2310000 |

---

<sup>(1)</sup> Audit fees for 2025 include fees associated with the issuance of comfort letters. Audit Fees for 2024 include amounts for the issuance of Forms S-8 and S-3 consents.

<sup>(2)</sup> Tax Fees for 2025 were for tax consulting services.

<sup>(3)</sup> All Other Fees for 2025 and 2024 consisted of amounts associated with independent actuarial reviews, reserve opinions, and consulting services. The Audit Committee has a pre-approval policy that requires pre-approval of audit, audit-related, and permitted non-audit services on an annual basis and authorizes the Audit Committee to delegate, to one or more of its members, pre-approval authority for permitted services. The Audit Committee delegated the authority to pre-approve audit, audit-related, and permitted non-audit services by KPMG LLP to the Audit Committee Chairperson, who is required to report any pre-approvals to the Audit Committee for ratification at its next meeting. In 2025, the Audit Committee pre-approved 100% of audit, audit-related, and permitted non-audit services, and concluded that KPMG LLP's provision of such services was compatible with the maintenance of KPMG LLP's independence in the conduct of its auditing functions.

**AUDIT COMMITTEE REPORT**

The Audit Committee oversees Selective's financial reporting processes on behalf of the Board. Management has the primary responsibility for overseeing the preparation of the financial statements and the overall reporting processes, including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee has:

◾ Periodically met with and held discussions with management regarding the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in Selective's financial statements.

---

---

| | |
|:---|:---|
| ◾ | Reviewed and discussed with KPMG LLP, Selective's independent registered public accounting firm, which is responsible for expressing an opinion on the conformity of those audited financial statements in accordance with U.S. generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of Selective's accounting principles and such other matters as are required to be discussed with the Audit Committee under the requirements of the Public Company Accounting Oversight Board, including the Statement on Auditing Standards No. 1301, "Communications with Audit Committees" as adopted by the Public Company Accounting Oversight Board, as may be modified or supplemented. |

---

---

| | |
|:---|:---|
| ◾ | Received the written disclosures and the letter from KPMG LLP required by the applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence and discussed with KPMG LLP its independence from Selective and its management. |

---

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board, and the Board approved, the inclusion of the audited financial statements in Selective's Annual Report on Form 10-K and any amendments thereto for the year ended December 31, 2025.

Submitted by the Audit Committee of the Board,

Terrence W. Cavanaugh, Chairperson H. Elizabeth Mitchell <br> Robert Kelly Doherty John S. Scheid <br> Thomas A. McCarthy

The Audit Committee Report does not constitute soliciting material, and shall not be deemed to be filed or incorporated by reference into any other Selective filing under the Securities Act or the Exchange Act, except to the extent that Selective specifically incorporates the Audit Committee Report by reference therein.

**STOCKHOLDER PROPOSALS AND NOMINATIONS**

***<u>Proposals for Inclusion in 2027 Proxy Statement</u>***

From time to time, stockholders may present proposals for inclusion in the proxy statement and consideration at an annual meeting.

We have delivered only one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We will promptly deliver, upon written or oral request, a separate copy of the proxy materials to any stockholder at the shared address to which a single copy of these documents was delivered.

Individual copies of the proxy and 2025 Annual Report can be requested by writing to Broadridge Financial Solutions, Inc., Householding Department, 51 Mercedes Way, Edgewood, New York 11717 or by calling 1-866-540-7095. If you are a stockholder and are currently sharing an address with another of our stockholders and wish to receive a separate copy of the proxy materials, have your future proxy materials householded, or your materials are currently householded and you would prefer to receive separate materials in the future, please make a request to change your householding status, as indicated above.

\* \* \* \* \* \* \* \*

It is important that your shares be represented at the Annual Meeting, regardless of the number of shares that you hold.
