Dear Olin Shareholder:

We cordially invite you to attend our 2025 annual meeting of shareholders (annual meeting) on May 1, 2025 .

This booklet includes the notice of the annual meeting and proxy statement, which describes the business we will conduct

at the annual meeting and provides information about Olin that you should consider when you vote your shares. We have

not planned a communications segment or any presentations for the 2025 annual meeting.

Whether or not you plan to attend, it is important that your shares are represented and voted at the annual meeting. If you

do not plan to attend the annual meeting, you may vote your shares online, by telephone or if you received paper copies

of our proxy materials by completing, signing and dating and returning a proxy card in the postage paid envelope

provided. Even if you plan on attending the annual meeting in person, we encourage you to vote your shares by

submitting your proxy in advance of the annual meeting.

At last year’s annual meeting close to 93% of our shares were represented in person or by proxy. We hope for the same

high level of representation at this year’s meeting and we urge you to vote as soon as possible.

Sincerely,
●

PROXY STATEMENT

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY

MATERIALS FOR THE 2025 ANNUAL MEETING OF SHAREHOLDERS

TO BE HELD ON MAY 1, 2025

Olin’s Notice of 2025 Annual Meeting of Shareholders and Proxy Statement and 2024 Annual Report on Form 10-

K are available at www.olin.com/proxy .

GENERAL QUESTIONS

Why did I receive a notice in the mail regarding the availability of proxy materials instead of printed copies of the

proxy materials?

In accordance with rules adopted by the U.S. Securities and Exchange Commission (SEC), we may furnish proxy

materials to the shareholders by providing access to these documents online instead of mailing printed copies. Unless you

are a participant in the Olin Corporation Retirement Savings Plan (RSP), you will not receive printed copies of the

materials unless you request them. Instead, we mailed you the notice regarding the availability of proxy materials (notice)

(unless you have previously consented to electronic delivery or already requested to receive printed copies), which

describes how you may access and review all of the proxy materials online. The notice regarding the availability of proxy

materials provides instructions as to how shareholders can access the proxy materials online, contains a listing of matters

to be considered at the meeting, and sets forth instructions as to how shares can be voted. Shares must be voted either in

person, online, by telephone, or by completing and returning a proxy card. Shares cannot be voted by marking, writing on

and/or returning the notice regarding the availability of proxy materials. Any notices regarding the availability of proxy

materials that are returned will not be counted as votes. Instructions for requesting a paper copy of the proxy materials are

included on the notice regarding the availability of proxy materials.

This process is designed to expedite shareholders’ receipt of proxy materials, lower the cost of the annual

meeting, and help conserve natural resources. However, if you prefer to receive printed proxy materials via mail or receive

an e-mail with links to the electronic materials, please follow the instructions included on the notice regarding the

availability of proxy materials.

Why did I receive this proxy statement?

You received this proxy statement because you owned shares of Olin common stock, $1 par value per share,

which we sometimes refer to as common stock or shares, at the close of business on March 3, 2025 . Olin’s Board of

Directors (Board) is asking you to vote at the annual meeting FOR each of our director nominees identified in Item 1, and

FOR Items 2 and 3 listed in the notice of the annual meeting of shareholders. This proxy statement describes the matters

on which we would like you to vote and provides information so that you can make an informed decision.

When was the notice regarding the availability of proxy materials distributed to shareholders?

We began to distribute the notice regarding the availability of proxy materials to shareholders via mail and email

on or about March 21, 2025 .

When was this proxy material mailed to shareholders?

We began to mail the proxy statement and form of proxy to shareholders on or about March 21, 2025 .

What if I have questions?

If you have questions, please write them down and send them to the Office of the Secretary at Olin Corporation,

190 Carondelet Plaza, Suite 1530, Clayton, MO 63105 USA.

Proxy Statement Table of Contents

What will I be voting on?

You will be voting on:

(1) the election of nine directors identified in this proxy statement;

(2) an advisory vote to approve the compensation for named executive officers (NEOs);

(3) the ratification of the appointment of KPMG LLP (KPMG) as Olin’s independent registered public accounting

firm for 2025 ; and

(4) any other business properly presented at the annual meeting.

Could other matters be voted on at the annual meeting?

As of March 21, 2025 , the items listed in the preceding question are the only matters being considered. If any

other matters are properly presented for action, the persons acting as proxies will vote each proxy in accordance with their

good faith business judgment as to what is in the best interests of Olin.

How does our Board recommend I vote on the proposals?

Our Board recommends a vote FOR each of the director nominees identified in Item 1, and FOR Items 2 and 3.

What is a broker non-vote?

A broker non-vote occurs when brokers, banks or other nominees holding shares for a beneficial owner have

discretionary authority to vote on “routine” matters brought before a shareholder meeting, but the beneficial owner of the

shares fails to provide the broker, bank or other nominee with specific instructions on how to vote on any “non-routine”

matters brought to a vote at the shareholders meeting.

Brokers, banks and other nominees will be entitled to vote your shares on “routine” matters without instructions

from you. The only proposal that would be considered “routine” in such event is the proposal for the ratification of the

appointment of KPMG as Olin’s independent registered public accounting firm. A broker, bank or other nominee will not be

entitled to vote your shares on any “non-routine” matters, absent instructions from you. “Non-routine” matters include the

election of directors, and the approval, on a non-binding advisory basis, of the compensation paid to Olin’s NEOs. If you

are a shareholder that holds shares through an account with a broker, bank or other nominee, please provide specific

voting instructions to your broker, bank or other nominee.

Consequently, if you do not submit any voting instructions to your broker, bank or other nominee, your broker,

bank or other nominee may exercise its discretion to vote your shares only on the proposal to ratify the appointment of

KPMG. If you do not direct your broker, bank or other nominee as to how your shares should be voted, your shares will

constitute broker non-votes on each of the other proposals. Broker non-votes will count for purposes of determining

whether a quorum exists, but will not be counted as votes cast with respect to such proposals.

What do I need to do to attend the annual meeting in person?

Each attendee must bring a valid, government-issued photo ID, such as a driver’s license or passport, and

verification of Olin common stock ownership. For a shareholder of record (a shareholder with a stock certificate or who

holds shares in an account with our transfer agent, EQ Shareowner Services) or RSP participant, please bring your notice

of the annual meeting or the upper half of your proxy card. If you hold your shares in an account with a broker, bank or

other nominee (i.e., your shares are held in street name), please bring the notice or voting instruction form you received

from your broker, bank or other nominee. You may also bring your brokerage or bank account statement reflecting your

Olin common stock ownership as of March 3, 2025 , the record date for voting. If you hold your shares through a broker,

bank or other nominee, you will not be permitted to vote at the meeting without obtaining a “legal proxy” from that

nominee.

Please note that cameras, sound or video recording equipment, mobile phones and other similar devices, as well

as purses, briefcases, backpacks and packages, will not be allowed in the meeting room. No one will be admitted to the

meeting once it begins.

VOTING

Who can vote?

All shareholders of record at the close of business on March 3, 2025 , are entitled to vote at the annual meeting.

How many votes can be cast by all shareholders?

At the close of business on March 3, 2025 , the record date for the annual meeting, we had 115,083,118

outstanding shares of common stock. Each shareholder on the record date may cast one vote for each full share owned.

The presence in person or by proxy of the holders of a majority of such outstanding shares constitutes a quorum. If a

share is present for any purpose at the meeting, it is deemed to be present for the transaction of all business. Abstentions

and shares held in street name (broker shares) that are voted on any matter will be included in determining the number of

votes present. Broker shares that are not voted on any matter at the meeting will not be included in determining whether a

quorum is present.

How do I vote if I am not the shareholder of record?

If you are not the shareholder of record but hold shares through an account with a broker, bank or other nominee,

the broker, bank or other nominee may have special voting instructions that you should follow. Please see the materials

sent to you by your broker, bank or other nominee for information on how to vote your shares.

If you want to vote in person at the annual meeting, and you own Olin common stock in an account with a broker,

bank or other nominee, you must obtain a legal proxy from that party in their capacity as owner of record for your shares

and bring the legal proxy to the annual meeting.

How do I vote if I am the shareholder of record?

You may vote either in person at the annual meeting or by proxy. To vote by proxy, you must select one of the

following options:

• Vote online:

• Access the website listed in the proxy materials you received.

• Have the notice regarding the availability of proxy materials and/or your proxy card in hand.

• Follow the instructions provided on the website.

• Return the proxy card in the postage paid envelope provided. We must receive the proxy card no later

than April 28, 2025 for RSP participants or no later than April 30, 2025 for all other shareholders, for your

vote to be counted.

If you vote in a timely manner online or by telephone, you do not need to return the proxy card for your vote to

count.

Where can I access an electronic copy of the Proxy Statement and Annual Report on Form 10-K for the year

ended December 31, 2024 ?

You may access an electronic, searchable copy of the Proxy Statement and the Annual Report on Form 10-K for

the year ended December 31, 2024 , at www.olin.com/proxy.

How are votes counted?

If you specifically mark the proxy card (or vote online or by telephone) and indicate how you want your vote to be

cast regarding any matter, your directions will be followed. If you sign and submit the proxy card but do not specifically

mark it with your instructions as to how you want to vote, the proxy will be voted FOR the election of our director nominees

named in Item 1, and FOR Items 2 and 3. If you submit a proxy card marked “abstain” on any item, your shares will not be

voted on that item so marked and your vote will not be included in determining the number of votes cast on that matter.

Broker shares that are not voted in the election of director nominees in Item 1 or on Item 2 will not be included in

determining the number of votes cast on those matters.

As of the date of this proxy statement, our Board knows of no business other than that set forth above to be

transacted at the annual meeting, but if other matters requiring a vote do arise, it is the intention of the persons acting as

proxies to whom you are granting your proxy to vote in accordance with their good faith business judgment as to what is in

the best interests of Olin on such matters.

EQ Shareowner Services tabulates the shareholder votes and provides an independent inspector of election as

part of its services as our registrar and transfer agent.

Can I change my vote?

Yes. If you are a shareholder of record, you can revoke a proxy or change your vote before the completion of

voting at the meeting by:

• casting a new vote online or by telephone;

• submitting another written proxy with a later date;

• sending a written notice of the change in your voting instructions to the Office of the Secretary at Olin

Corporation, 190 Carondelet Plaza, Suite 1530, Clayton, MO 63105 USA if received no later than April 28,

2025 for RSP participants or no later than April 30, 2025 for all other shareholders; or

• revoking the grant of a previously submitted proxy and voting in person at the annual meeting. Please note

that your attendance at the annual meeting itself will not revoke a proxy.

If your shares are held in street name, you should follow the instructions provided by your broker, bank or other

nominee to revoke or change your voting instructions.

When are the votes due?

Proxies submitted by shareholders online or by telephone will be counted in the vote only if they are received no

later than April 30, 2025 by 11:59 p.m. Eastern Time. Shares voted using a proxy card will be counted in the vote only if

we receive your proxy card no later than April 30, 2025 . Proxies submitted by RSP participants will be counted in the vote

only if they are received by mail, online or by telephone no later than April 28, 2025 by 11:59 p.m. Eastern Time.

ITEM 1—PROPOSAL FOR THE ELECTION OF DIRECTORS

Who are the individuals nominated by our Board to serve as directors?

Each director nominee will be elected annually for a one-year term ending at the next annual meeting (in this

case, the 2026 annual meeting) and until his or her successor is elected and qualified or until his or her earlier death,

resignation, disqualification or removal.

Our Board has nominated Beverley A. Babcock, Edward M. Daly, Matthew S. Darnall, Kenneth T. Lane, Julie A.

Piggott, Earl L. Shipp, William H. Weideman, W. Anthony Will and Carol A. Williams to serve as directors for a one-year

term expiring at our 2026 annual meeting.

All nominees are presently Olin directors who were elected by Olin shareholders at the 2024 annual meeting

except for Edward Daly who is standing for election for the first time. Gen. Daly joined the Board on March 5, 2025. As

part of its responsibilities to seek out and consider candidates for election as directors, the Nominating and Governance

Committee engaged a third-party director search firm that identified Gen. Daly to the Nominating and Governance

Committee. The Nominating and Governance Committee considered Gen. Daly and recommended to the Board that he

be appointed as a director in March, 2025. C. Robert Bunch, age 70, who has served as a member of our Board since

2005, will retire from our Board following the completion of his current term. As a result, our Board will be reduced to nine

members on the date of the annual meeting. Proxies cannot be voted for a greater number of individuals than the number

of nominees.

Our Board expects that all of the nominees recommended by it will be able to serve as directors. If any nominee is

unable to accept election, a proxy voting in favor of such nominee will be voted for the election of a substitute nominee

selected by our Board, unless our Board reduces the number of directors.

Our Board recommends a vote FOR the election of Beverley A. Babcock, Edward M. Daly, Matthew S.

Darnall, Kenneth T. Lane, Julie A. Piggott, Earl L. Shipp, William H. Weideman, W. Anthony Will and Carol A.

CORPORATE GOVERNANCE MATTERS

How Many Meetings Did Board Members Attend?

During 2024, our Board held six meetings. As part of each regularly scheduled Board meeting, the non-employee

directors met in executive session without management present. Each incumbent director attended 100% of the

aggregate total number of meetings held by the Board and all Board Committees on which he or she served. We have a

policy requiring directors to attend each annual meeting, absent serious extenuating circumstances. All of our directors

who were members of our Board at the time of our 2024 annual meeting participated in our 2024 annual meeting.

Which Board Members Are Independent?

Our Board has determined that each of the director nominees named above, except Kenneth T. Lane, is

independent in accordance with applicable New York Stock Exchange (NYSE) listing standards and applicable provisions

of our Principles of Corporate Governance. Additionally, our Board determined that Mr. Bunch, who is not standing for re-

election at the annual meeting, is also independent in accordance with applicable NYSE listing standards and applicable

provisions of our Principals of Corporate Governance. In determining independence, our Board confirms that a director

has no relationship with Olin that violates the “bright line” independence standards under the NYSE listing standards. Our

Board also reviews whether a director has any other material relationship with Olin, after consideration of all relevant facts

and circumstances. In assessing the materiality of a director’s relationship to Olin, our Board considers the issues from

the director’s standpoint and from the perspective of the persons or organizations with which the director has an affiliation.

Our Board reviews commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships.

16

Proxy Statement Table of Contents

Our Board has adopted criteria for the types of de minimis transactions that do not warrant Board consideration

when making director independence determinations. Our Board has concluded that the following transactions do not

impair a director’s independence, and are not considered by our Board in its determination of director independence:

• our match of up to $5,000 in charitable contributions made by directors under our 50% matching contribution

program; and

• any transaction or series of transactions between Olin (or its subsidiaries) and a director (or an organization in

which he/she serves as a director, partner, shareholder or officer) for the purchase or sale of products or

services that (i) involve less than $50,000 in the aggregate in any 12-month period and (ii) have the same

pricing and other terms and conditions as transactions with unrelated and similarly situated customers or

suppliers.

Except as provided below, during 2024, none of our current non-employee directors or director nominees had any

relationship or transaction other than those which are permitted under the de minimis criteria described above.

In 2024, we purchased approximately $2,036,000 of energy-related services from National Grid US, a subsidiary

of National Grid plc. One of our directors, Earl Shipp, is a member of the Board of Directors of National Grid plc, chair of

such Board’s Safety & Sustainability Committee and is a member of such Board’s People and Governance Committee.

Our Board determined that Mr. Shipp had no material interest in these transactions, and they did not impair Mr. Shipp’s

independence because the transactions were made on customary terms and conditions and were immaterial relative to

annual sales of both companies.

In 2024, we sold a gross aggregate of approximately $1,142,000 of chlor alkali products to CF Industries

Holdings. One of our directors, Anthony Will, is the President and Chief Executive Officer and a member of the Board of

Directors of CF Industries Holdings. Our Board determined that Mr. Will had no material interest in these sales

transactions and they did not impair Mr. Will’s independence. The Board based its decision on the facts that the business

relationship preceded Mr. Will joining our Board and remained consistent with prior years, and the transactions were made

on customary terms and conditions and were immaterial relative to annual sales of both companies.

Does Olin Have Corporate Governance Guidelines and a Code of Conduct?

Our Board has adopted Principles of Corporate Governance and a Code of Conduct. Our Code of Conduct

applies to our directors and all of our employees, including our chief executive officer (CEO), chief financial officer (CFO)

and principal accounting officer/controller. We discuss certain provisions of these documents in more detail under the

heading “CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.”

Each of our Board Committees (Audit, Compensation, Nominating and Governance, and Executive) acts under a

written charter adopted by our Board. Our Committee charters can be viewed on our website at www.olin.com/investors/

leadership-governance/committees . Our Principles of Corporate Governance and Code of Conduct can all be viewed on

our website at www.olin.com/investors/leadership-governance/governance-documents . In addition, we will disclose on that

website any amendment to, or waiver from, a provision of our Code of Conduct for our directors and executive officers,

including our CEO, CFO, principal accounting officer/controller or other employees performing similar functions. The

contents of our website referenced in this section are not and should not be considered to be part of this proxy statement.

Does Olin Have an Insider Trading Policy?

Olin has adopted an insider trading policy that governs the purchase, sale and/or other dispositions of our

securities by employees, officers, directors of Olin, and their family members and entities they control. The insider trading

policy is designed to promote compliance with insider trading laws, rules and regulations as well as the listing standards of

the NYSE. In addition, with regard to Olin’s trading in its own securities, it is Olin’s policy to comply with the federal

securities laws and the listing standards of the NYSE.

Does Olin Prohibit Hedging and Pledging of Its Stock by Insiders?

Our insider trading policy prohibits our directors and executive officers from engaging in any hedging or pledging

transactions in our securities. Our policy does not specifically permit any type of hedging transaction, but instead imposes

a broad prohibition of any “hedging or monetization transactions” if the director or executive officer “continues to own the

17

Proxy Statement Table of Contents

underlying security without all the risks and rewards of ownership.” Our prohibition on pledging of our securities is similarly

broad, and prohibits all pledges of our securities, whether as part of a hedging transaction or a loan transaction.

As of March 3, 2025 , no shares of our common stock were pledged by any director or executive officer.

Do Olin’s Board and Committees Conduct Evaluations?

As required by NYSE rules, Olin’s Board as well as its Audit, Compensation, and Nominating and Governance

Committees each conduct an annual performance evaluation. In addition, Olin’s Board conducted individual evaluations of

all non-employee directors during 2024.

As part of their review of Board nominations, our Board and our Committee consider a variety of experience and

background in an effort to ensure that the composition of our directors ensures a strong and effective Board. Our

Principles of Corporate Governance cite strength of character, an inquiring and independent mind, practical wisdom and

mature judgment as among the principal qualities of an effective director. Our Board is committed to advancing diversity

on the Board, including diversity of thought, qualifications, attributes, skills and perspectives, experience, gender, ethnicity,

race, age and cultural and geographic background, and interviewing a diverse slate of director candidates.

This year, we have nine nominees standing for election.

A shareholder can suggest a person for nomination as a director by providing the name and address of the

candidate, and a detailed description of the candidate’s experience and other qualifications for the position, in writing

addressed to the Secretary at Olin Corporation, 190 Carondelet Plaza, Suite 1530, Clayton, MO 63105 USA. The notice

may be sent at any time, but for a candidate to be considered by our Committee as a nominee for an annual meeting, we

must receive the written information at least 150 days before the anniversary of the date of our prior year’s proxy

statement. For example, for candidates to be considered for nomination by our Committee at our 2026 annual meeting,

we must receive the information from shareholders on or before October 22, 2025 .

In addition to shareholders proposing candidates for consideration by our Committee, Olin’s Bylaws allow

shareholders to directly nominate individuals at our annual meeting for election to our Board by delivering a written notice

as described under the heading “MISCELLANEOUS—How can I directly nominate a director for election to the Board at

the 2026 annual meeting?” on page 6 .

What Is the Board Leadership Structure?

At least annually, our Board evaluates the Board leadership structure to ensure the Board’s optimal and

independent oversight of Olin’s senior management and business. When evaluating the optimal structure, our Board

reviews a variety of criteria, including Olin’s strategic goals, and the composition and skills set of the directors and senior

management. Our Principles of Corporate Governance state that our Board may select either a combined CEO Board

chair coupled with an independent lead director, or appoint a Board chair who does not also serve as CEO. This approach

allows our Board to separate or combine the two roles based on our needs in light of the dynamic environment in which

we operate and our Board’s assessment of Olin’s leadership needs at that time.

From April 22, 2021 until the appointment of Mr. Kenneth Lane as President and CEO and Director on March 18,

2024, our Board operated under the structure of combined CEO and Chairman of the Board, coupled with an independent

lead director. Since the appointment of Mr. Lane, our Board has separated the roles of CEO and Chairman by appointing

Mr. Weideman as Chairman and eliminating the lead director role. Our Board believed that this change in Board

leadership structure was appropriate given Mr. Lane’s new role at Olin, concurrent with the change in our Board’s

composition and senior management. This separation of the roles of the CEO and Chairman allowed Mr. Lane to focus on

his new roles and responsibilities, while allowing Mr. Weideman to exercise his independent oversight and leadership over

the Board.

Our Board will continue to evaluate its leadership structure at least once a year, or earlier as appropriate, to help

maintain the Board leadership model best suited for Olin and its shareholders.

How Does the Board Oversee Olin’s Risk Management Process?

Our Board is responsible for oversight of Olin’s risk assessment and management process, including monitoring

our response to important public policy issues, as well as oversight of strategic, human resources, financial, operational,

security, environment, health and safety, and legal compliance matters. These processes and structures include Olin’s

Enterprise Risk Management (ERM) process, Code of Conduct and related compliance program, internal control function

and disclosure controls, and a robust internal audit function.

Our e nvironment, social and governance ( ESG) and corporate social responsibility strategy is overseen by our

Board as a part of its oversight of our overall strategy and risk management.

21

Proxy Statement Table of Contents

Our Board has delegated to our Compensation Committee basic responsibility for oversight of management’s

compensation risk assessment, and that Committee reports to our Board on its review.

Our Board also delegated tasks related to risk process oversight to our Audit Committee, which reports the results

of its review process to our Board. Our Audit Committee’s process includes:

• a review, at least annually, of our internal audit process, including the organizational structure and staff

qualifications, as well as the scope and methodology of the internal audit process;

• reviewing activity and special reports of Olin’s Internal Audit and Environmental, Health, Safety &

Transportation (EHS&T) Audit functions including management responses and corrective action plans for

significant findings;

• a review, at least annually, of our enterprise risk management (ERM) program to ensure that an appropriate

ERM process is in place, including discussion of the major risk exposures identified by Olin, the key strategic

plan assumptions considered during the assessment and steps implemented to monitor and mitigate such

exposures on an ongoing basis; and

• a review and discussion, at least annually, with senior management regarding our assessment and

management of risks and exposures related to cybersecurity and information technology, including steps

taken to mitigate and manage the same.

In addition to the reports from our Audit and Compensation Committees, our Board periodically discusses risk

oversight, including as part of its annual detailed corporate strategy reviews. Such discussions include our Board’s

detailed review of risks identified in the ERM process when analyzing and formulating our corporate strategy and other

times during the year, as deemed necessary.

Brian J. Clucas, our Vice President, Global Internal Audit, Ethics and Compliance reports directly to our Audit

Committee and has direct and unrestricted access to that Committee. Todd A. Slater, our Senior Vice President and CFO,

oversees our ERM process and fulfills the responsibilities of a chief risk officer. Mr. Slater reports to our CEO, but has

direct access to our Audit Committee chair. Messrs. Slater and Clucas, individually or with other members of our

management team, periodically meet in executive session with our Audit Committee.

REPORT OF OUR AUDIT COMMITTEE

Our Audit Committee’s primary responsibility is to assist our Board in its oversight of the integrity of Olin’s financial

reporting process and systems of internal control, to review Olin’s enterprise risk management process, to evaluate the

independence and performance of Olin’s independent registered public accounting firm, KPMG LLP (KPMG), and internal

audit functions and to encourage private communication between our Audit Committee and KPMG and our internal

auditors.

Our Committee held five meetings during the year. During the second half of 2024 , our Audit Committee also

completed a self-assessment.

In discharging its responsibility, our Audit Committee reviewed and discussed the audited consolidated financial

statements for fiscal year 2024 with management and KPMG, including the matters required to be discussed by applicable

requirements of the Public Company Accounting Oversight Board (PCAOB) and the U.S. Securities and Exchange

Commission (SEC) .

In addition, our Audit Committee has received the written disclosures and the letter from KPMG required by

applicable requirements of the PCAOB regarding KPMG’s communications with our Audit Committee concerning

independence. Our Audit Committee discussed with KPMG the issue of its independence from Olin and reviewed KPMG’s

reports on the firm’s quality review procedures and findings, results of peer reviews and investigations and inquiries,

including corrective actions taken. Our Audit Committee also negotiated the hiring of KPMG for the 2024 audit and pre-

approved all fees which SEC rules require our Audit Committee to approve to ensure that the work performed was

permissible under applicable standards and would not impair KPMG’s independence.

Based on our Audit Committee’s discussions with management and KPMG and our Audit Committee’s review of

KPMG’s written report and the other materials discussed above, our Audit Committee recommended that our Board

include the audited consolidated financial statements in Olin’s Annual Report on Form 10-K for the year ended

December 31, 2024 , to be filed with the SEC.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Our Principles of Corporate Governance and our Code of Conduct include policies and procedures requiring prior

review and oversight of certain transactions involving our directors, director nominees, employees and their immediate

family members and affiliated organizations if Olin is a direct or indirect participant. Our Principles of Corporate

Governance require our Nominating and Governance Committee (or, if that Committee determines it is appropriate,

another independent body of our Board) to conduct a prior review of all “related party transactions” for potential conflicts of

interest and prohibit any such transaction if it determines it to be inconsistent with the interests of our company and

shareholders. Related party transactions are those which are required to be disclosed under Item 404 of Regulation S-K,

which currently includes transactions where Olin was or is to be a participant and the amount exceeds $120,000 and in

which any “related person” has a direct or indirect material interest. A “related person” means a director, director nominee,

executive officer, a beneficial owner of 5% or more of Olin’s outstanding voting securities, or “immediate family members”

of any of the foregoing. Immediate family members means a child, stepchild, parent, stepparent, spouse, sibling, mother-,

father-, son-, daughter-, brother-, or sister- in-law, or any person (other than a tenant or employee) sharing the household

of such specified person.

Our Principles of Corporate Governance require our Nominating and Governance Committee to pre-approve

service by any of our executive officers (our CEO and other Section 16 officers) on the Board of another public company

or on the Board of any private company that would represent a material commitment of time. Our Principles of Corporate

Governance prohibit any of our executive officers from serving on the Board of a company for which one of our non-

employee directors serves in any management capacity. In addition, our Code of Conduct and related Corporate Policy

Statements require the approval of our Board before an officer may serve as a director or provide services to another

organization (as an officer, employee, consultant, etc.). Any such service by other employees must be pre-approved by

our management, if the potential for a conflict of interest exists. These provisions also prohibit any employee or family

member from having any significant (i.e., over 10% ownership, or is a director, officer or partner) direct or indirect interest

25

Proxy Statement Table of Contents

in, or any involvement with or obligation to, any business organization that does or seeks to do business with Olin, or any

Olin competitor, without pre-approval from the employee’s department head.

In granting pre-approval, our Nominating and Governance Committee, Board members and management focus

on the best interests of Olin.

In addition to the pre-approval process described above, our Code of Conduct and related Corporate Policy

Statements prohibit any director or employee from engaging in a transaction that might conflict with the best interests of

Olin.

There were no related person transactions during 2024.

CORPORATE RESPONSIBILITY

Olin consistently demonstrates a commitment to excellence in protecting the environment and health, safety, and

security of our employees and the communities surrounding our global operations. Our Board is responsible for

overseeing our Environmental, Social, and Governance (ESG) and corporate social responsibility strategy, as part of their

broader oversight of our overall strategy and risk management efforts. We publish an ESG Scorecard that outlines our

targets and progress in key areas where we believe Olin can have the most significant impact.

Olin’s Sustainability strategy statement highlights our commitments:

Olin will increase value for our investors, employees, and customers through our focused ESG actions and

investments. We will:

• Protect our employees and communities through our industry-leading occupational and process safety

programs

• Proudly strengthen United States defense, international defense, law enforcement, and conservation through

our Winchester ammunition brand

• Significantly reduce environmental impact by taking concrete steps driving technological efficiencies,

productivity, and innovation to lower our carbon footprint, net water usage, and resource consumption

• Developing and enabling sustainable solutions within the value chain through our product and service

offerings

• Consistently uphold our Olin values and governance standards as we amplify our culture of inclusion and

cultivate our diverse global workforce.

Olin’s industry leadership, focused ESG actions, and our engaged people create a positive, long-lasting impact on

our communities and the environment.

Our Chemical division maintains third-party certification internationally recognized standards, including ISO

14001:2015 standard for environmental management systems. Our product stewardship policy ensures that our product

safety performance is properly evaluated, and continuously improved, and relevant elements are made publicly available.

We regularly audit our environmental, health, safety and transportation programs and performance against applicable

legal requirements and our own internal standards, the results of which are regularly reviewed with the Audit Committee of

our Board.

We commit to provide our employees with a safe and supportive environment and maintain a steadfast

commitment to safely producing and distributing o ur products. Our global workforce is committed to ME Principles which

focus on each individual’s responsibility for their own safety and that of others, on leading by example, on reinforcing

positive behaviors, and on elevating concerns.

The Board’s Compensation Committee has structured our compensation program to balance financial results with

Olin’s achievement of annual goals relating to environmental impact, safety, sustainability, and ethical conduct.

Additionally, our Board comprehensively reviews Olin’s talent management aspects related to sustainability. We have

engaged with shareholders on sustainability matters and are publicly transparent regarding our ESG and sustainability

platform and progress in key areas, including the more than 70,000 hours of volunteerism in 2024 with organizations in

the communities where our offices and plants are located.

Introduction

This Compensation Discussion and Analysis (CD&A) describes the objectives, principles, and components of the

material elements of our 2024 compensation programs for our Named Executive Officers (NEOs) as well as decisions

made by our Compensation Committee. Our NEOs for 2024 were:

Name	Title
Kenneth T. Lane	President and CEO
Todd A. Slater	Senior Vice President and CFO
Brett A. Flaugher	Vice President and President, Winchester
Dana C. O'Brien	Senior Vice President, Chief Legal Officer
Florian J. Kohl	Vice President and President, Epoxy & International
Scott M. Sutton	Former President and CEO
Patrick M. Schumacher	Former Vice President and President, Chlor Alkali Products and Vinyls
Damian Gumpel	Former Vice President, Corporate Strategy

On September 1, 2023, Olin announced that President and CEO Scott Sutton would step down from his role

during the first half of 2024. Effective March 18, 2024, the Board appointed Kenneth Lane as President and CEO and

also elected Mr. Lane to the Board. Also effective March 18, 2024, Mr. Sutton transitioned to the role of Special Advisor

until his departure on June 30, 2024.

Olin and Mr. Lane agreed to a 2024 compensation package which consisted of base salary, short term incentive

target, long term incentive target and an initial equity award of 200,000 restricted stock units that vest over three years

following his start date. The initial equity award was granted to replace compensation Mr. Lane forfeited upon his

termination from his prior employer and induce him to join Olin. The Compensation Committee chose to grant restricted

stock units as part of the initial equity grant to further enhance both the attractiveness and retentive value of Mr. Lane’s

compensation package. This initial award had a grant date fair value of approximately $11.0 million. In March 2024, Mr.

Lane also was awarded an annual equity award of $7,000,000 (50% in stock options, 50% performance shares).

On January 15, 2025, Mr. Gumpel notified Olin of his intention to resign effective February 22, 2025.

Executive Summary

Select 2024 Financial and Business Highlights

• In 2024, Olin’s chemicals businesses continued to navigate a challenging industrial environment, and the

Winchester business continued to see softening demand for its Commercial products as customers took longer to

deplete their large inventories while demand for Military products was strong. This difficult economic environment

was buffered by each business (Chlor Alkali Products & Vinyls, Epoxy, and Winchester) employing a value first

strategy and exercising diligence in controlling costs.

• Olin maintained our market leadership positions in all three businesses, as reflected in our Levered Free Cash

Flow generation in 2024 of $408.4 million, which the company utilized to repurchase approximately 5.9 million of

Olin’s outstanding shares. Since the beginning of the share repurchase program in 2021, we have spent $2.6

billion to repurchase 49.6 million shares or approximately 31% of shares outstanding.

• Winchester completed the successful acquisition of White Flyer Targets, LLC in late 2023. Demand for White

Flyer targets was robust and a positive driver for Winchester’s 2024 results. White Flyer will soon benefit from the

launch of our Eco Flyer product line which will be the next evolution of clay targets.

• Our commitment to safety in 2024 resulted in no loss of life events, with Winchester achieving the second best

safety performance in its history. We did not achieve the rigorous process safety targets for our Chemicals

businesses and have renewed our efforts for 2025.

• Management continued to encourage and support productivity projects throughout the company and for full year

2024, the company achieved more than $250 million in productivity efficiencies.

• We also continued to show good progress toward the pro-rata achievement of our sustainability objectives,

reducing our total carbon emission by 4% from 2023 and revised our 2030 reduction target to 35% from 25%.

• Additionally, Olin employees engaged at a level that resulted in more than 70,000 hours of volunteerism in 2024,

an increase of approximately 11% year over year.

Pay for Performance

Consistent with our compensation philosophy of designing policies and practices that align executive pay with

company performance objectives and shareholder values, each NEO has a target total direct compensation opportunity

that is reviewed annually by our Compensation Committee. As illustrated by the following charts, the majority of

compensation that may be earned by our NEOs is tied to the achievement of short-term incentive (STIP) and long-term

incentive (LTIP) financial performance metrics. Additionally, total compensation fluctuates based on the underlying value

of the common stock granted under our LTIP. The CEO chart below represents the target values for Mr. Lane.

Say on Pay Results

At the 2024 annual meeting of our shareholders, we held an advisory vote on executive compensation.

Approximately 96.6% of the shares voted were cast in support of our 2024 executive compensation and related

disclosures. Our Compensation Committee viewed the results of this vote as general, broad shareholder support for our

executive compensation program. While we made no changes to our executive compensation program specifically as a

result of that vote, our Compensation Committee continuously evaluates our executive compensation program and makes

changes to respond to market trends and other relevant factors.

We review our compensation philosophy, practices and policies regularly to ensure they are in line with market

best practices, including alignment of executive pay and company performance, focus on sustainable growth,

encouragement of both short- and long-term performance results, and talent recruitment and retention. Identified below

are some of our more significant practices and policies that were in effect during 2024 and were designed to reinforce our

compensation philosophy.

What We Do — ☑	Align Pay and Performance: By tying our executives’ pay to Olin’s actual results, our compensation programs (i) align our executives’ interests with those of our shareholders and (ii) induce our management team to achieve our most important goals. Each NEO has a target total direct compensation opportunity that is reviewed annually by our Compensation Committee to ensure alignment with Olin’s pay for performance objectives.	What We Don’t Do — ☒	No Option Repricing: We prohibit option repricing without shareholder approval.
☑	Use Appropriate Peer Groups When Establishing Compensation Opportunities: We established a peer group to help us review market practices and design a competitive compensation program. We set compensation of our executive officers at levels that we believe are appropriate relative to the compensation paid to similarly situated officers of our peers, also giving consideration to market and other factors.	☒	No Excessive Perquisites: We do not provide our NEOs with excessive perquisites.
☑	Maintain an Independent Compensation Committee and Consultant: Compensation decisions for our NEOs are approved by a Compensation Committee composed of non-employee independent directors. In addition, our Compensation Committee is advised by an independent consultant who reports directly to the Compensation Committee and provides no other services to Olin or its management.	☒	No Tax Gross-Ups: We do not provide “gross-ups” to any of our named executive officers, including gross-ups for any excise taxes imposed with respect to Section 280G or Section 409A of the Code.
☑	Perform Regular Risk Assessments: We regularly assess the risk inherent in our compensation policies and programs to ensure mitigation of operational, financial, legal, regulatory, strategic and reputational risks.	☒	No Hedging or Pledging: We do not allow our NEOs to hedge or pledge our stock.
☑	Maintain a Clawback Policy: Each of our NEOs is subject to a clawback policy applicable to all of Olin’s executive officers, as defined by Section 16 of the Exchange Act. The policy generally allows Olin to recover compensation (including cash and/or equity awards) previously paid to an executive officer in the event of a financial restatement that impacts the applicable performance metric if, in the opinion of our Board or Compensation Committee, the revision would have resulted in a lower payment or award.	☒	No Payment of Dividends on Unvested Equity Awards: Payment of dividends or dividend equivalents for all equity awards is subject to the same vesting conditions as the underlying award.
☑	Maintain a Stock Ownership Policy: We maintain a stock ownership policy that requires our executive officers to maintain stock ownership (excluding unvested performance share unit awards) equal to a set multiple of base salary. Covered executives have five years from the date the guidelines apply to attain the required stock ownership levels. The base salary multiple is 6 for the CEO, 3 for any Senior Vice President, and 2 for any Vice President. As of December 31, 2024, all covered executives were in compliance, to the extent possible, with the stock ownership policy.	☒	No Automatic Compensation Increases: We do not automatically increase NEO’s base salary or total compensation opportunities each year.

Compensation

Committee

• Our Compensation Committee consists of directors who are independent under the NYSE

listing criteria.

• Our Compensation Committee establishes all elements of our total compensation

opportunity for executive officers, including our NEOs, and certifies achievement under

performance awards, when applicable.

• Our Compensation Committee takes into account a multitude of factors when setting total

compensation opportunity, including but not limited to recommendations from qualified

third parties (e.g., CEO and independent compensation consultant), job responsibilities,

qualifications, performance, business growth, and market practices.

• Our Compensation Committee routinely meets in executive session (with no officers

present) and, as appropriate, invites third party advisors to attend.

Management

• For non-CEO executive officers, our CEO reviews and provides feedback on individual

performance and makes recommendations on total compensation opportunity to our

Compensation Committee.

Independent

Compensation

Consultant

• To assist in performing its duties, our Compensation Committee engages Exequity, an

independent board and management advisory firm. Exequity solely served the

Compensation Committee and the committee determined that Exequity had no conflicts of

interest in providing services to the committee and was independent under the NYSE

factors for compensation consultants.

• As advisor to our Compensation Committee, Exequity assisted in reviewing the total

compensation strategy and pay levels for our NEOs; recommended appropriate peer

group comparisons; examined all aspects of our executive compensation program to

ensure ongoing support; and provided general advice to our Compensation Committee on

all compensation decisions pertaining to our executive officers.

Compensation Process: Roles and Responsibilities

Our Compensation Committee is the body primarily responsible for overseeing executive officer compensation,

working closely with management and our independent compensation consultant, Exequity LLP (Exequity), to establish

total compensation opportunities. Below is an overview of the decision-making process, considerations, and the role of

each key party.

Peer Group Data

In designing and implementing our executive compensation programs, our Compensation Committee reviews

compensation data from a peer group that is determined and periodically adjusted, in consultation with Exequity (referred

to as the “comparator group”). Our Compensation Committee is not bound to mirror the comparator group standards but

does consider comparator group norms as one factor to help ensure market competitive compensation practices. For

2024 compensation decisions, the comparator group referenced by the Compensation Committee was comprised of the

following 21 chemicals companies, that were identified as reasonably aligned with our revenues, industry affiliation, and

corporate structure:

Air Products and Chemicals, Inc.	The Chemours Company	International Flavors & Fragrances, Inc.
Albemarle Corporation	Corteva, Inc.	The Mosaic Company
Avient Corporation	DuPont de Nemours, Inc.	PPG Industries, Inc.
Axalta Coating Systems Ltd.	Eastman Chemical Company	RPM International, Inc.
Cabot Corporation	Ecolab Inc.	The Scotts Miracle-Gro Company
Celanese Corporation	FMC Corporation	The Sherwin-Williams Company
CF Industries Holdings, Inc.	Huntsman Corporation	Westlake Chemicals Corporation

What We Pay and Why: Elements of Compensation

Overview of Elements of Compensation

There are three primary elements of our total direct compensation package: base salary; short-term incentive

opportunities; and long-term incentive awards (equity-based). In addition, we provide market competitive retirement and

change in control protections.

Compensation Element	Description	Objectives
Base Salary	Fixed compensation that is reviewed annually based on, for example, scope of responsibilities, tenure, market value, and individual performance.	Rewards day-to-day value of executives consistent with the market. Attract, retain and motivate qualified and experienced executives.
Short-Term Incentives	“At-risk” compensation earned based on performance measured against pre- established annual goals. 80% of each NEO’s award is tied to company and/or division financial performance with the remaining 20% to the achievement of non- financial goals.	Ties compensation to the achievement of short-term company goals and objectives. Motivates executives to achieve short-term financial targets and non-financial strategic objectives that ultimately contribute to long- term company growth and shareholder return.
Long-Term Incentives	“At risk” compensation comprised of 50% performance shares and 50% stock options, with the value fluctuating according to shareholder value. Performance share units vest based on achievement of relative Total Shareholder Return (TSR) and Net Income. Stock options vest based on continued service.	Motivates executives to achieve long-term goals that benefit shareholders, aligning financial interests of executives and shareholders. Coordinates activities of all NEOs in support of long-term organizational value enhancement. Rewards continuous service with the company.
Other Compensation and Benefits	Broad-based benefits provided to Olin employees (e.g., health insurance and retirement plan participation) and the availability of a nonqualified deferred compensation plan. Market competitive severance and change in control packages.	Provide a total compensation package that is market competitive to allow us to recruit and retain executive talent. Allow executives to focus on generating shareholder value and ensure personal indifference to the outcome of a transaction in the event of a change in control.

Base Salary

The salaries of our NEOs are reviewed on an annual basis by the Compensation Committee based on our

compensation philosophy and considering merit, promotion, and change in role or market rates, as applicable. Salary

changes for our NEOs are typically approved by the Compensation Committee in December and generally take effect in

the following January.

Following its annual review, the Compensation Committee approved increased base salaries for Messrs. Slater,

Kohl, Flaugher, and Schumacher and Ms. O’Brien effective January 1, 2024 . The Compensation Committee approved an

additional adjustment for Mr. Kohl in connection with his appointment as Vice President and President, Epoxy &

International on June 1, 2024. Mr. Sutton did not receive an increase due to his planned departure.

Short-Term Incentive Program (STIP )

STIP Performance Measures. Our Compensation Committee makes annual cash awards under our STIP.

Actual STIP payouts are calculated as a percentage of base salary and based on our achievement with respect to pre-

established performance metrics, as discussed below. For 2024 , the STIP awards for all executive officers, including our

NEOs, were based 80% on financial targets and 20% on non-financial goals. The Compensation Committee’s philosophy

is to establish performance targets such that if Olin meets expectations, the executives have the opportunity to receive a

target payout. Further, performance that exceeds or does not meet expectations shall result in payouts above or below

34

Proxy Statement Table of Contents

target, respectively.

For NEOs with corporate wide responsibility, Messrs. Lane, Slater, and Gumpel and Ms. O’Brien, the financial

targets were based entirely on corporate performance. Corporate financial targets for 2024 included Adjusted EBITDA

and Levered Free Cash Flow. Adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization)

represents our net income (loss) plus an add-back for depreciation and amortization, interest expense (income), income

tax provision (benefit), other expense (income), restructuring charges (income) and certain other non-recurring items.

Levered Free Cash Flow represents our cash flow after interest paid, income taxes paid, changes in working capital,

capital expenditures and payments under long-term supply contracts.

For NEOs with divisional responsibility, Messrs. Kohl, Flaugher, and Schumacher, the financial targets were

further divided with 60% based on division performance and 20% based on corporate performance. Corporate financial

targets are the same as described above for NEOs with corporate wide responsibility. Division financial targets for 2024

included Division Adjusted EBITDA and Division Adjusted Cash Flow. Division Adjusted EBITDA represents our segment

results plus an add-back for depreciation and amortization and certain other non-recurring items. Division Adjusted Cash

Flow represents our Division Adjusted EBITDA adjusted for changes in working capital and reduced by capital

expenditures and payments under long-term supply contracts.

For 2024 , the Compensation Committee approved non-financial objectives including the following categories:

Safety, Health & Environmental Goals and Strategic Goals. Each division shared equally the accountability for the

achievement of the non-financial objectives.

Determination of Financial Performance Metric Achievement. As noted above, financial targets applied to

80% of the 2024 STIP for each NEO.

The table below shows the 2024 thresholds, targets, and maximum as well as corresponding results and payout

percentages for all applicable financial targets. Dollar amounts in the table below are shown in millions.

Performance Measure	Performance Threshold	Performance Target	Performance Maximum	Actual Performance	Actual Payout Percentage
Adjusted EBITDA—Corporate	$ 1,080.0	$ 1,500.0	$ 1,800.0	$ 1,000.2	—%
Levered Free Cash Flow—Corporate	$ 493.2	$ 685.0	$ 822.0	$ 408.4	—%
Adjusted EBITDA—Chemicals Division	$ 940.3	$ 1,306.0	$ 1,567.2	$ 816.0	—%
Adjusted Cash Flow—Chemicals Division	$ 756.0	$ 1,050.0	$ 1,260.0	$ 673.7	—%
Adjusted EBITDA—Winchester Division	$ 229.7	$ 319.0	$ 382.8	$ 271.7	44.1%
Adjusted Cash Flow—Winchester Division	$ 189.4	$ 263.0	$ 315.6	$ 238.8	16.7%

For 2024, in calculating Adjusted EBITDA, we used 2024 EBITDA excluding the effect of the following special

charges, gains and losses (which were reflected in our 2024 EBITDA): (i) restructuring charges of $33.3 million and (ii)

$126.3 million of charges related to Hurricane Beryl.

Determination of Non-Financial Performance Metric Achievement. As noted above, non-financial goals

applied to 20% of the 2024 STIP for each NEO. After reviewing performance, as discussed below, the Compensation

Committee determined all applicable NEOs earned 16.0% of their target STIP award based on non-financial performance

in the aggregate.

Non-Financial Category	Percentage Earned
Strategic Goals	15.0%
Safety, Health & Environmental Goals	1.0%

STIP Opportunities and Payments. The STIP opportunities and payouts for 2024 were as follows:

NEO	Threshold	Target	Maximum	Earned
Kenneth T. Lane	$ 429,000	$ 1,072,500	$ 2,145,000	$ 171,600
Todd A. Slater	$ 240,000	$ 600,000	$ 1,200,000	$ 96,000
Brett A. Flaugher	$ 216,000	$ 540,000	$ 1,080,000	$ 332,640
Dana C. O'Brien	$ 200,000	$ 500,000	$ 100,000	$ 80,000
Florian J. Kohl	$ 180,000	$ 450,000	$ 900,000	$ 72,000
Patrick M. Schumacher	$ 144,000	$ 360,000	$ 720,000	$ 57,600
Damian Gumpel	$ 176,000	$ 440,000	$ 880,000	$ 70,400

Long-Term Incentive Compensation Program (LTIP)

For 2024 , the Compensation Committee set the following target LTIP award levels which were allocated equally

between performance share units and stock options.

NEO	Target Award
Kenneth T. Lane	$ 7,000,000
Todd A. Slater	$ 1,680,000
Brett A. Flaugher	$ 1,200,000
Dana C. O'Brien	$ 1,100,000
Florian J. Kohl	$ 600,000
Patrick M. Schumacher	$ 1,200,000
Damian Gumpel	$ 1,100,000

Performance Share Units. Half the value of each NEO’s 2024 LTIP target award value was delivered in

performance share units (PSUs). The target number of PSUs awarded to each NEO was formulated by dividing half the

NEO’s target award value by the fair market value of our common stock (the average of the high and low per share sales

price of our common stock on the NYSE on the grant date). The total number of PSUs that vest and will be paid to each

NEO from awards made in 2024 will vary between 0% and 200% of this target number. The grant date fair value of PSUs

as reported in the Grants of Plan-Based Awards table is greater than the targeted value due to the accounting rules under

ASC Topic 718.

Half of the target number of PSUs will be earned based on our relative TSR over the three-year period ending

December 31, 2026 compared to the community of companies in the S&P 1500 Material Index, plus one selected direct

competitor—Huntsman Corporation (collectively, the Performance Share Comparison Group), as shown in the table

below. TSR for Olin and the Performance Share Comparison Group companies is calculated using a 20-trading day

average stock price.

Olin’s Relative TSR Percentile	Percentage of Relative TSR PSUs Earned
80.0 or More	200%
Greater than 50.0, but Less than 80.0	100% plus 3.33% for each incremental percentile above the 50.0
50.0	100%
Greater than 20.0, but Less than 50.0	25% plus 2.5% for each incremental percentile above the 20.0
20.0	25%
Less than 20.0	0%

36

Proxy Statement Table of Contents

The remaining half of the target number of PSUs will be earned based on our actual net income compared to the

applicable net income goal set by our Compensation Committee for each year and the cumulative three-year net income

goal. At the beginning of each year during the performance period, our Compensation Committee sets an annual net

income goal. At the beginning of the third year of the performance period, the Compensation Committee sets both the

third annual net income goal and approves the three-year net income goal, which represents the aggregate of the three

annual net income goal amounts. The annual net income goals are weighted 20% per year and the cumulative net

income goal is weighted 40% for the entire three-year period. The Compensation Committee sets performance goals for

net income PSUs in this manner due to the Company’s cyclical earnings. This gives the Committee the flexibility to set

goals based on expectations for each year while also measuring aggregate performance vs. target over the full

performance cycle.

The actual amount of PSUs earned with respect to each goal will be based on our net income as a percentage of

the applicable goal, as shown in the table below:

Olin’s Net Income as Percentage of Goal	Percentage of Net Income PSUs Earned (1)
140% or More	200%
100%	100%
60%	50%
Less than 60%	0%
(1) To the extent Olin’s net income falls in between the outlined target achievements, the shares earned will be determined based on linear interpolation.

Stock Options. The remaining half of each NEO’s 2024 LTIP target award value is delivered in stock options.

The number of shares subject to the option award is determined by dividing half the value of the overall LTIP target by the

Black-Scholes value of options for our common stock (not to be lower than 20% of the then-current market price of our

common stock).

In 2024 , our Compensation Committee approved the granting of option awards effective on February 22, 2024 .

The exercise price on February 22, 2024 was $52.29 per share, the average of the high and low per share sales price of

our common stock on the NYSE on that date. The stock options vest in three, equal annual installments, generally

contingent on the NEO’s continued employment. All options have an exercise period of 10 years from the grant date,

which may be shortened in the event of a recipient’s termination of employment. Our plans and policies do not permit

“back dating” of options.

Restricted Stock Units. Through 2024, the Compensation Committee did not award restricted stock units to

NEOs on a regular basis, but awarded restricted stock units in the case of an NEO new hire and promotion as outlined

below.

In March, 2024, as part of his initial compensation package, Mr. Lane was granted 200,000 restricted stock units

(RSUs) vesting as follows:

• First Anniversary of Start Date: 50,000 RSUs

• Second Anniversary of Start Date: 50,000 RSUs

• Third Anniversary of Start Date: 100,000 RSUs

In connection with his promotion to Vice President and President, Epoxy & International, Mr. Kohl received an

equity grant of 5,000 RSUs vesting as follows:

• First Anniversary of Start Date: 1,250 RSUs

• Second Anniversary of Start Date: 1,250 RSUs

• Third Anniversary of Start Date: 2,500 RSUs

2022 LTIP Award. In February 2022, as part of our annual LTIP award cycle, our Compensation Committee

granted PSU awards to Messrs. Slater, Flaugher, Sutton, Schumacher, and Gumpel and Ms. O’Brien, who were each

executive officers at that time. The PSU awards were granted according to the award structure and vesting conditions

described above with a performance period covering 2022 through 2024. Our relative TSR percentile ranking for the 2022

through 2024 performance period was 22.76% as compared to our Performance Share Comparison Group resulting in a

vesting at 31.90% for relative TSR PSUs. Our net income performance was 97.92% for 2022, 60.47% for 2023, 0.00% for

37

Proxy Statement Table of Contents

2024, and 71.71% for the 2022 to 2024 cumulative period resulting in an aggregate payout percentage of 60.36% for our

net income PSUs.

As a result of our relative TSR and net income performance our NEOs earned the following number of PSUs

under their 2022 LTIP awards:

NEO	Target 2022 LTIP PSUs	2022 LTIP Aggregate Payout %	2022 LTIP PSUs Earned
Todd A. Slater	15,100	46.13%	6,965
Brett A. Flaugher	8,000	46.13%	3,691
Dana C. O’Brien	9,100	46.13%	4,197
Scott M. Sutton	72,400	46.13%	33,399
Patrick M. Schumacher	10,100	46.13%	4,142
Damian Gumpel	10,100	46.13%	4,659

Other Compensation

We offer a small number of other personal benefits, such as certain life insurance benefits and the retirement and

change in control benefits described below, to groups of employees, including our NEOs. We extend some benefits, such

as a portion of health insurance premiums and certain retirement benefits, to all eligible employees. We tie the size and

construction of these benefits to competitive practices in the market, a decision our Compensation Committee believes

enables us to attract and retain executives with the talents and skill sets we require.

Retirement Benefits. The Olin Corporation Retirement Savings Plan (RSP) is a qualified, defined contribution

401(k) plan that provides eligible employees the opportunity to make pre-tax, Roth 401(k), after-tax and catch-up

contributions. Olin generally matches a portion of eligible compensation that the participant contributes to the plan and

makes additional employer contributions based on a percentage of eligible compensation, as defined in the RSP.

The Supplemental RSP is an unfunded, nonqualified deferred compensation plan for our NEOs and a select

group of other senior management employees that is described in greater detail under the heading “Nonqualified Deferred

Compensation.” Our Compensation Committee believes that offering this benefit has allowed us to remain competitive in

the market for qualified senior-level executive talent.

We also maintain three, frozen defined benefit plans – a qualified pension plan and two nonqualified plans.

Messrs. Slater, Flaugher, and Gumpel are the only NEOs with an accrued benefit under a frozen defined benefit pension

plan.

Executive Severance Plans. The Compensation Committee believes that severance protections play a valuable

role in attracting, motivating, and retaining highly talented executives. As a result, each NEO is party to an Executive

Severance Plan, as are described under the headings “Potential Payments Upon Termination or Change in Control” and

“Executive Severance Plans.”

Sutton Consulting Bonus. As previously reported, we entered into a Transition Agreement with Mr. Sutton, our

former President and CEO in connection with his departure from the company. Pursuant to the terms of the Transition

Agreement, Mr. Sutton earned a Consulting Bonus of $1,750,000 based on his completion of special advisor services

through June 30, 2024. The Consulting Bonus is paid in two equal installments – the first was paid shortly after his

services ended and the second was paid in February 2025. Mr. Sutton also has agreed to and his right to receive the

Consulting Bonus is contingent on him abiding by various restrictive covenants, including noncompetition, non-solicitation

of customers and non-raiding of employees covenants following his departure from the company.

O’Brien Retention Bonus. The company entered into a letter agreement with Ms. O’Brien that amended her

2023 Retention Agreement in connection with her upcoming retirement at the end of 2025. The letter agreement provides

her the opportunity to earn retention bonus payments totaling $1,000,000; provided that she works continuously through

July 31, 2025 and assists with the transition of her successor through December 31, 2025. If she meets the necessary

conditions, the unvested portion of her retention bonus award ($900,000 unvested at the end of 2024) will vest on the

regularly-scheduled vesting dates.

38

Proxy Statement Table of Contents

Looking Forward to 2025

In October 2024, the Compensation Committee approved certain changes to the mix of LTIP awards for 2025,

which will consist of 60% PSUs and 40% time-vested restricted stock units. The change in mix for the LTI awards more

closely aligns Olin with its peers, increases the emphasis on performance-conditioned pay, and supports the

Compensation Committee’s belief that restricted stock units are less dilutive to shareholders and, as full value awards,

more strongly incentivize executive retention. In addition, beginning in 2025, all PSU awards granted maintain double

trigger vesting conditions in the event of a change in control.

In December 2024, the Compensation Committee approved a Financial Advisory/Wealth Management Service

and an Executive Health Assessment, both of which will be available beginning in 2025. These actions demonstrate

Olin’s commitment to holistic executive welfare and more closely aligns Olin with its peers. These benefits are intended to

help our executives alleviate health and wealth-related stress, thereby enhancing their focus on professional

responsibilities.

Risk Assessment

Our Compensation Committee, in consultation with management, regularly evaluates the risks involved with our

compensation programs. In November 2024, we conducted a comprehensive risk assessment considering factors such

as the plan metrics, number of plan participants, maximum payments, and risk mitigation factors. Exequity reviewed the

risk assessment and advised our Compensation Committee of its comfort with the level of risk inherent in our

compensation programs. Following our Compensation Committee’s review of the risk assessment and Exequity’s input,

our Compensation Committee concluded that it did not believe any of our compensation programs or policies create risks

that are reasonably likely to have a material adverse impact on Olin.

Tax and Accounting Considerations

All elements of compensation, including salaries, generate charges to earnings under generally accepted

accounting principles (GAAP). We generally do not adjust compensation based on accounting factors. Our

Compensation Committee takes into consideration the tax deductibility of compensation, to the extent practical, but

reserves the right to authorize payments that may not be deductible if it believes that the payments are appropriate and

consistent with our compensation philosophy.

Compensation Committee Report

The compensation committee has reviewed and discussed the Compensation Discussion and Analysis with

management and, based on the review and discussions, recommends that it be included in Olin’s 2024 annual report on

Form 10-K and Proxy Statement for the 2025 annual meeting of shareholders.

(3) Amounts listed in this column are 2024 STIP payouts, as described in the CD&A under the heading “What We Pay

and Why: Elements of Compensation - Short-Term Incentive Program (STIP).”

(4) Amounts reported in this column represent the total change in the present value of the pension benefits during the

applicable year under our defined benefit pension plans. Pension values as of December 31, 2024 for Mr. Slater

include amounts under the Qualified Plan, Supplemental Plan, and Senior Plan and for Mr. Flaugher include amounts

under the Qualified Plan and Supplemental Plan. Additionally, Mr. Gumpel participates solely in a cash balance

arrangement under the Qualified Plan. Other than Messrs. Slater, Flaugher and Gumpel, none of the NEO’s

participate in the defined benefit plans. Changes in the present value of pension benefits are determined using the

assumptions we use for financial reporting purposes and represent changes in assumptions and the fact that each

NEO is one year older, rather than any change in our NEO’s accrued pension benefit, except for Mr. Gumpel. The

retirement benefits for Mr. Gumpel reflects an account balance based on a "personal pension account” (PPA) Cash

Balance formula acquired from the Dow Employees Pension Plan (DEPP), which is then credited with interest until his

assumed retirement date. Please see the note entitled “Pension Plans” in the notes to our audited financial

statements included in our 2024 annual report on Form 10‑K for a discussion of these assumptions. To determine the

change in the present value of the pension benefits under these plans, for Messrs. Slater and Flaugher, we used age

62, and for Mr. Gumpel we used his current age, the first age at which unreduced pension benefits are payable under

the applicable Plans.

(5) Amounts reported in this column for 2024 are comprised of the following items:

NEO	RSP/Supplemental RSP– Retirement Account (a)	Other Payments (b)	Total
Kenneth T. Lane	$ 88,688	$ 31,872	$ 120,560

(a) The amounts shown represent Olin’s contributions of a total of 7.5% of eligible compensation to each of the RSP

and Supplemental RSP in addition to Olin’s match of a portion of eligible compensation that the participant

contributes to each plan.

• For Mr. Lane, a moving allowance paid in connection with his move to Olin’s corporate headquarters in

Clayton, Missouri.

• For Mr. Sutton, the payment of deferred compensation he received as a non-employee director prior to

becoming President & CEO of Olin on September 1, 2020 which became payable in 2024 upon his departure

from Olin.

Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table

Our NEOs are not employed under general employment contracts (other than the Transition Agreement and Offer

Letter described below). See “What We Pay and Why: Elements of Compensation” in the CD&A above for a discussion of

the material terms of our 2024 STIP and LTIP (performance share units and stock options). See “Potential Payments

Upon Termination or Change in Control” for a description of the Executive Severance Plans and other termination and

change in control provisions NEOs may be entitled to, including with respect to treatment of outstanding performance

share unit and stock option awards.

Lane Offer Letter. On February 15, 2024, Olin signed an offer letter with Mr. Lane (the “Offer Letter”). The Offer

Letter provides that Mr. Lane will serve as Olin’s President and Chief Executive Officer, be appointed to the Board, and

report solely to the Board. The Offer Letter entitles Mr. Lane to (a) a base salary at the rate of $1,100,000 per year, (b) a

2024 annual target incentive opportunity pursuant to the STIP equal to 130% of annual base salary (with a maximum

amount equal to 200% of target amount) prorated from his start date, and (c) subject to the approval of the Compensation

Committee, a 2024 LTIP award with a target grant date value of $7,000,000, with such award value to be allocated 50% to

stock options that vest based on continued employment and the balance to performance share units (with such

performance share units divided equally between units that vest based on (i) relative total shareholder return and (ii)

achievement of net income targets, each over a three year period). In connection with the start of Mr. Lane’s employment

with Olin, the Offer Letter provides for a one-time grant of 200,000 restricted stock units (the “Initial Equity Award”) under

the 2021 LTIP subject to Mr. Lane’s continued employment over a three-year period. Mr. Lane is required to relocate to

Olin’s headquarters, and, in connection with such relocation, will receive reimbursement under Olin’s corporate relocation

policy, which will be subject to repayment if he voluntarily terminates employment within 24 months of the effective date.

Sutton Transition Agreement. In 2023, we entered into a Transition Agreement with Mr. Sutton whereby he

would generally remain employed by Olin, either in his current role as President and CEO, or as a Special Advisor,

through a transition period that ended as of June 30, 2024 (the “End Date”). We believed that Mr. Sutton’s continued

presence at Olin during the transition period was critical to the ongoing success of the company, including maintenance of

important short-term and long-term strategic goals. We crafted a compensation package to adequately reflect his essential

role at Olin during the transition period. The Transition Agreement generally provided for the following compensation

package for Mr. Sutton: (i) continuation of Mr. Sutton’s base salary through the End Date (final payment made effective

June 30, 2024); (ii) payment of Mr. Sutton’s 2023 STIP award per the terms of the STIP (payment made in early March

2024); and (iii) payment of a Consulting Bonus (in staggered installments over the 2024 and 2025 fiscal years) - first

payment made effective June 30, 2024 with the second payment scheduled to be made no later than February 28, 2025.

With the final consulting payment made, in February 2025, all required payments will have been provided to Mr. Sutton.

Retention Agreements with Certain NEOs. On December 20, 2023, the Company entered into retention

agreements (each, a "Retention Agreement”) with Messrs. Slater, Flaugher, Kohl and Ms. O’Brien, which provide the

opportunity to earn a $1,000,000, and Mr. Gumpel, which provides an opportunity to earn a $600,000, cash retention

bonus payment (the "Retention Bonus”) based on continued employment. The Compensation Committee believed the

Retention Agreements were important to incentivize the executives to continue their employment with Olin and to promote

a successful executive leadership transition.

The executives vested in 10% of their retention bonus based on continued employment through July 1, 2024 and

may vest in the remainder of the Retention Bonuses, contingent on their continued employment, according to the following

vesting schedule:

Vesting Date	Vesting % of the Retention Bonus
January 1, 2025	20%
July 1, 2025	30%
January 1, 2026	40%

The Retention Agreements also include restrictive covenants, including non-competition, non-solicitation, and

confidentiality protections in favor of Olin.

(2) The shares listed in column (d) above represent performance share units paid in February 2024 (vested based on our

performance for the three years ended December 31, 2023 ), under a performance award made in early 2021 . In

addition, the shares listed in column (d) above also includes a restricted stock award granted on September 1, 2020

which vested on January 1, 2024 for Mr. Sutton and a restricted stock award granted on December 10, 2021 which

vested on December 10, 2024 for Mr. Gumpel. Mr. Sutton’s net shares delivered after 194,142 shares withheld for

taxes were 305,858. Mr. Gumpel’s net shares delivered after 5,298 shares withheld for taxes were 6,702.

(3) Performance share units are paid approximately half in cash and half in stock. The cash portion of the performance

share units payment was based on the fair market value of the shares as of December 31, 2023 ($54.18), and dollar

amounts listed in column (e) above for the stock portion of the payment of performance share units are based on the

average of the high and low sales price for our common stock as of February 22, 2024 , the date the shares were

issued ($52.29).

Pension Benefits

The following table shows the present value of the benefits under our defined benefit plans as of December 31,

2024 , for Messrs. Slater, Flaugher, and Gumpel. The remaining NEOs do not participate in any defined benefit plan.

Please see the item entitled “Pension Plan Assumptions” included in the “Pension Plans” footnote in the notes to our

audited financial statements included in our 2024 annual report on Form 10-K for a discussion of these assumptions.

(1) For Messrs. Slater and Flaugher, benefit accruals were frozen under both plans effective December 31, 2007.

Employment after that date continues to count toward meeting service and age requirements for vesting and early

retirement. Messrs. Slater and Flaugher have met the requirements for vesting and early retirement eligibility. The

amount in the DEPP for Mr. Gumpel was transferred into the Qualified Plan at the time of the Acquisition and the

benefit accruals were frozen at that time.

(2) The present values are calculated using Messrs. Slater and Flaugher’s frozen accrued benefits as of December 31,

2007 and an assumed retirement date of age 62 at which time they may receive unreduced benefits. For Mr. Gumpel,

his DEPP account balance as of December 31, 2015 is credited with annual interest until an assumed retirement date

of age 65 at which time he may receive his most valuable benefit. The assumptions we used for financial reporting as

of December 31, 2024, including a 5.7% single effective rate (in lieu of a discount rate) for the Qualified Plan, a 5.4%

single effective rate for the Supplemental Plan, and the PRI-2012 Blue Collar Mortality Tables for Annuitants and

Employees, with the Social Security Administration—2021 Intermediate Cost Projections Mortality Improvement

Scale.

(3) Amounts in this column assume that benefits are paid in the form of an annuity during the executive’s lifetime. The

executive may instead elect payment of benefits under any of the available payment forms under these plans,

including payments for the executive’s life (which we sometimes refer to as a “single life annuity”) or payments

continuing after the executive’s death for the life of his or her spouse (which we refer to as a “joint and survivorship

benefit”). Under the Qualified Plan and the Supplemental Plan, benefit payments are reduced from the single life

annuity based on actuarial calculations if the executive elects a different payment form.

(4) All accrued benefits under the Supplemental Plan were paid out in connection with the required payments made in

2015 to participants in connection with the October 2015 acquisition of the U.S. chlor alkali and vinyl, global

chlorinated organics, and global epoxy business of Dow (the Acquisition) (such payments, the Required NQ Plan

47

Proxy Statement Table of Contents

Payments). At the time of the Acquisition, Messrs. Slater and Flaugher had not reached retirement age, so they have

residual benefits under these plans.

Qualified Plan

As part of our benefits program, we offered a defined benefit retirement plan to salaried employees hired before

January 1, 2005 through our Qualified Plan. In 2005, we amended the Qualified Plan to close participation, so that

salaried employees hired on or after January 1, 2005, are not eligible. Benefits accrued by most salaried participants in

the Qualified Plan, including Messrs. Slater and Flaugher, were “frozen” effective December 31, 2007.

Benefits under the Qualified Plan are calculated based on the average cash compensation (salary and annual

incentive) for the highest three years out of the last 10 years the individual was employed by Olin, through December 31,

1. An employee’s benefit is generally 1.5% of his or her average compensation during the relevant period multiplied

by the number of years of service, less a percentage of his or her primary Social Security benefit based on years of

service (not to exceed 50% of such Social Security benefit). Participants who are at least age 55 with at least 10 years of

service when they leave Olin may elect to receive a benefit immediately that is reduced by 4% for each year the

participant is younger than age 62 at the time benefit payments begin. Participants who leave Olin before age 55 (with 10

or more years of service) may elect to receive an actuarially reduced benefit with payments beginning at age 55 or later.

Participants who leave Olin before age 65 with at least five years of service (but less than 10 years of service) receive a

vested retirement benefit beginning the month after their 65th birthday. Benefits from the Qualified Plan generally are paid

as an annuity with the form of payment (e.g. joint and survivorship benefit, guaranteed period, etc.) selected by the

participant, subject to any applicable actuarial reductions.

In conjunction with the Acquisition, the Qualified Plan assumed responsibility for certain Dow-related frozen

benefits. Specifically, nearly all frozen benefits transferred to the Qualified Plan are associated with two benefit formulae—

Pension Equity and Cash Balance—eligibility for which is typically determined by the individual participant’s hire date at

Dow. The Cash Balance benefit, in which Mr. Gumpel participates, also provides a frozen account balance that grows

with interest (at a different rate) until separation from Olin, at which point the participant can elect an immediate annuity, a

deferred annuity or a lump sum.

Supplemental Plan

The Supplemental Plan is a frozen unfunded, nonqualified deferred compensation plan for select management

employees and those at specified compensation levels. The Supplemental Plan both restores benefits limited by the

Code and provides benefits on certain compensation excluded from coverage under the Qualified Plan. Benefits accrued

by most salaried participants in the Supplemental Plan, including Messrs. Slater and Flaugher, were “frozen” effective

December 31, 2007. The formula used to calculate pension benefits under the Supplemental Plan is the same as under

the Qualified Plan, without the Code limitations on benefits and eligible compensation, reduced by the amount payable

under the Qualified Plan. Early retirement benefits have similar eligibility and use the same reduction factors as the

Qualified Plan.

As noted above, previously accrued benefits in the Supplemental Plan were required to be paid to participants as

part of the Required NQ Plan Payments in connection with the Acquisition. At the time of the Acquisition, Messrs. Slater

and Flaugher had not reached retirement age and so they have residual benefits under these plans for their early

retirement allowances.

(1) Amounts in this column are included in the Base Salary column of the Summary Compensation Table.

(2) Amounts in this column are included in the All Other Compensation column of the Summary Compensation Table and

represent Olin matching contributions and retirement account contributions to the participants’ Supplemental RSP

account.

Our Supplemental RSP provides deferral and company matching opportunities to employees eligible to participate

in the RSP whose contributions are limited under the Code because their base pay exceeds the Code’s compensation

limit. These employees can make pre‑tax contributions to the Supplemental RSP after their eligible compensation

reaches the Code limit under the RSP. For these purposes, eligible compensation generally includes base salary but

excludes incentive compensation. Employees who contribute to the Supplemental RSP receive matching contributions

from Olin at the same level Olin matches RSP contributions. In addition, Olin provides the same retirement contributions

to the Supplemental RSP as under the RSP (5% or 7.5%, depending on the employee’s age) on the amount of the excess

eligible compensation. For these purposes, eligible compensation generally includes base salary and short‑term incentive

compensation, but excludes long‑term incentive compensation. Employees may elect to have their contributions to the

Supplemental RSP invested in phantom shares of Olin common stock or select from an approved list of phantom

investment options.

Potential Payments Upon Termination or Change in Control

We have two executive severance plans that cover our NEOs – one, the Olin Corporation Severance Plan for

Section 16(b) Officers (Severance Plan), covers certain qualifying terminations and the other, the Olin Corporation

Change in Control Severance Plan for Section 16(b) Officers (CIC Severance Plan), covers certain qualifying terminations

that occur in connection with a change in control. We refer to the Severance Plan and CIC Severance Plan as the

Executive Severance Plans. The terms of the 2024 STIP and LTIP awards also include provisions addressing treatment

on a qualifying termination, whether or not in connection with a change in control. A qualifying termination is generally

considered to have occurred in connection with a change in control if it occurs within two years following the change in

control. The value of benefits under the Supplemental RSP and, for Messrs. Slater and Flaugher, the Supplemental Plan

is disclosed under the headings “Nonqualified Deferred Compensation” and “Pension Benefits” above, respectively. Our

LTIP provisions contain double trigger vesting provisions in the event of a change in control.

All payments and other benefits under the Executive Severance Plans are subject to the executive’s execution

and non-revocation of, and continued compliance with, a separation release agreement. The separation release

agreement includes a general release of all claims against Olin and the executive’s compliance with restrictive covenants

provided under the Executive Severance Plans, including ongoing non-disparagement requirements with respect to Olin

and certain non-competition and non-solicitation covenants during the executive’s severance period. The executive,

regardless of the circumstances of the executive’s termination of employment, would also be prohibited from disclosing

our trade secrets and other confidential information.

49

Proxy Statement Table of Contents

A summary of the benefits available on December 31, 2024 in different scenarios under the terms of our

Executive Severance Plans, 2024 STIP, and LTIP is provided below. Key terms used in the Executive Severance Plans

are generally defined as follows:

“Cause” generally means an NEO’s (i) willful and continued failure to substantially perform duties; (ii) willful

engagement in gross misconduct significantly financially injurious to Olin; (iii) willful breach of Olin’s Code of

Conduct; or (iv) willful misconduct that is a felony or fraud in the course of employment.

“Good Reason” means the executive terminates his or her employment (after appropriate notice and an

opportunity to cure) because (i) the executive is required to relocate by more than fifty miles; (ii) the executive’s

salary is reduced or is not increased on a basis consistent with the salary system for executive officers in place

before the change in control; (iii) the employer fails to maintain the executive’s incentive compensation plans or

health, welfare and retirement plans on substantially the terms in effect prior to the change in control; or (iv) the

executive is assigned duties inconsistent with the executive’s position prior to the change in control, or (v) the

employer takes actions that result in a diminution of the executive’s responsibilities or a substantial reduction in

resources to carry out his duties.

“Change in Control” generally means:

(1) a person or entity acquires beneficial ownership (as defined in the Exchange Act) of 20% or more of our

common stock unless (a) the acquiring party is Olin, our subsidiaries or our benefit plans, an underwriter

holding the shares temporarily for an offering, or a group that includes the executive who is a participant in the

CIC severance plan or an entity that such executive controls, (b) the percentage increase occurs solely

because the total number of shares outstanding is reduced by Olin repurchasing its stock or (c) the

acquisition is directly from Olin;

(2) a majority of our board members change (other than new members elected or nominated by at least 2/3 of the

then-current board, unless such new member became a director pursuant to an actual or threatened proxy

contest or similar dispute);

(3) we (or any of our subsidiaries) sell all or substantially all assets, or merge or engage in a similar transaction,

unless, immediately following such transaction, (a) our shareholders own a majority of the voting interest of

Olin or its successor (in approximately the same ratios as before the transaction) and (b) neither of the events

described in items (1) or (2) above has occurred for Olin or its successor; provided that a transaction that

would otherwise constitute a change in control under this item (3) will not be considered a change in control if:

(i) at least a majority of our board members immediately before the transaction remain as board members

after the transaction, (ii) at least 75% of our executive officers immediately before the transaction remain as

executive officers after the transaction, and our board members at the time of approval of the transaction

determine in good faith that such executive officers are expected to remain as executive officers for a

significant period after the transaction, and (iii) 2/3 of such board members determine that the transaction

shall not be deemed to be a change in control; or

(4) our shareholders approve a plan of complete liquidation or dissolution of Olin.

Termination by Olin without Cause not in Connection with a Change in Control

• an amount equal to the sum of (i) the executive’s annual salary and (ii) the executive’s target annual cash

incentive opportunity for the year of termination, payable in twelve equal monthly installments;

• if the termination occurs in the last three quarters of the year, a pro-rated STIP payment for the year of termination

based on Olin’s actual performance and payable at such time such incentive payments are payable to other

employees of Olin;

• a pro-rata share of unvested performance share unit awards (based on actual Olin performance for the full

performance period) payable in cash at the time it would otherwise be payable;

• payment of any unvested Retention Bonus;

• the continuation of medical, dental and life insurance benefits for the executive and his or her dependents for a

Tabular Disclosure

The following tables show estimated compensation payable to each NEO who was employed on December 31,

2024 , upon various triggering events (assuming the event occurred on December 31, 2024 ). Actual amounts can only be

determined upon the triggering event. Amounts in the tables assume an annual salary at the level in effect on December

31, 2024. These tables do not account for any cutback that may result from the application of the CIC Severance’s Plans

Code Section 280G provision. If payments and benefits under the CIC Severance Plan to an executive would constitute

an “excess parachute payment” under Code Section 280G and subject the executive to golden parachute excise taxes

under Code Section 4999, the CIC Severance Plan utilizes a “best net after-tax” payment approach which reduces the

executive’s payments and benefits to an amount that results in the greatest after-tax benefit for the executive, taking into

account any such excise tax and any applicable federal, state and local taxes.

staggered installments over the 2024 and 2025 fiscal years with the first payment made effective June 30, 2024 and the

second payment scheduled to be made no later than February 28, 2025. All required payments will have been provided to

Mr. Sutton as of February 28, 2025.

Patrick M. Schumacher. Mr. Schumacher separated from Olin on September 1, 2024 by mutual agreement.

Proxy Statement Table of Contents

Because Mr. Schumacher executed and did not revoke a signed Separation Agreement and General Release, he is

receiving the following Separation Benefits for the period beginning September 1, 2024 and ending on August 31, 2025:

• Executive Severance equal to twelve (12) months of his base salary at the time of his separation plus his 2024

Target Bonus, with the full amount being equal to $1,200,000 payable in semi-monthly installments of $50,000

beginning September 13th. All payments are subject to tax withholdings required by law.

• 2024 Short Term Incentive Program (STIP) Payment, prorated based on active employment through August 31,

2024 ($57,600) with payment to be made when all other STIP participants receive their approved payouts in early

March 2025.

• Long-Term Incentive Programs. For all vested options, Mr. Schumacher is eligible to exercise these options for up

to one year from the Separation Date of September 1, 2024. Additionally, Mr. Schumacher is eligible for a payout

under the 2022 Performance Share Program. His payout was based on the number of months worked during the

performance period (32 of 36 months) with the payout to be made in cash and paid out at the same time as other

participants (estimated value of $138,923 as of December 31, 2024). Additionally, Mr. Schumacher will be eligible

for a pro-rata payout for the 2023 Performance Share Grant based on the number of months worked during the

performance period (20 of 36 months), with the payout again being made in cash and paid out at the time all other

participants receive a payout. All other unvested options and performance share units were forfeited.

• Mr. Schumacher was also eligible to continue to participate in Olin’s medical and dental programs for himself and

his dependents, which he elected to do, for the duration of his separation payments. Premiums were withheld

from his severance payments. He was also eligible for outplacement counseling which he has not elected to

utilize.

DIRECTOR COMPENSATION

The Compensation Committee is responsible for reviewing and establishing the compensation of our non-

employee directors that is externally competitive and designed to align the interests of the directors with our shareholders.

In discharging this responsibility, the Compensation Committee considers recommendations from Exequity. The annual

stock grant, retainer stock grant, and cash retainer are paid for the 12-month period running from May 1 to April 30, with

payments made on or about May 1.

For 2024 , the Board approved the following cash fees and equity compensation:

Element of Compensation	Amount	Election
Annual Stock Grant	$ 115,000	(1)
Annual Retainer - Stock	$ 40,000	(2)
Annual Retainer - Cash	$ 100,000	(3)
Additional Lead Director Retainer	$ 30,000	(3)
Additional Nominating and Governance Committee Chair Retainer	$ 15,000	(3)
Additional Compensation Committee Chair Retainer	$ 20,000	(3)
Additional Audit Committee Chair Retainer	$ 25,000	(3)
Elections: (1) Automatically credited as phantom stock units in the Director’s deferred stock account. (2) Must be taken in shares of common stock or credited as phantom stock units in the Director’s deferred stock account. (3) Must be taken in cash or either (i) credited as phantom stock units in the Director’s deferred stock account or (ii) credited to the Director’s deferred cash account.

In addition, the directors are eligible to participate in a charitable gift program, where we make a 50% matching

contribution (up to a total of $5,000 per year) for the director’s gifts to charities that meet the requirements of Code

Section 501(c)(3).

54

Proxy Statement Table of Contents

On December 13, 2024, the Board of Directors approved and implemented revisions to the compensation of its

non-employee directors, now incorporated into the Amended and Restated 1997 Stock Plan for Non-Employee Directors

to become effective in 2025 as shown the following table:

Element of Compensation	Amount	Increased from 2024
Annual Stock Grant	$ 140,000	Yes
Annual Retainer - Stock	$ 60,000	Yes
Annual Retainer - Cash	$ 100,000	No
Additional Lead Director Retainer	$ 35,000	Yes
Additional Nominating and Governance Committee Chair Retainer	$ 20,000	Yes
Additional Compensation Committee Chair Retainer	$ 25,000	Yes
Additional Audit Committee Chair Retainer	$ 30,000	Yes
Additional Non-Executive Board Chair Retainer	$ 150,000	N/A

The changes were approved after a review of the director compensation programs of peer group companies as

prepared by the Compensation Committee’s independent consultant, Exequity. The peer group companies used for the

analysis are the same as used for executive pay comparisons. The changes position Olin closer to the median pay of

peer group companies, though with a greater emphasis on equity compensation than the median peer.

The fair market value for determining the number of shares included in all phantom stock unit and common stock

awards described above is equal to the average of the high and low sales price of our common stock on May 1 of the

applicable year or the first day in May on which the NYSE is open for trading.

Under the Directors Plan, directors may choose to defer the cash portion of their compensation to their cash or

stock accounts. We credit their deferred accounts with quarterly interest (on the cash portion), and separately pay

dividend equivalents (on the phantom stock portion). Phantom stock units are paid out in shares of our common stock or,

at the director’s election, in cash upon the director leaving our Board, or at one or more later dates selected by the

director. We also pay the balance of any deferred account to the director if there is a change in control (e.g., in the event

a person or group acquires 40% or more of our assets, 30% or more of our stock, or a majority of the market value or

voting power of our stock, or a majority of our board members are not endorsed by the directors in office at the time of

election).

The following table shows all compensation earned or received by each of our non-employee directors during

2024 . Mr. Sutton received a payment of his deferred director account in connection with his departure from the Board

during 2024. Mr. Lane did not receive any additional compensation for his service as a director.

(1) In 2024 , Messrs. Bunch, Darnall, and Will, and Ms. Piggott elected to receive all or a portion of their compensation in

deferred cash or phantom stock units credited to their respective deferred cash and stock accounts under the

Directors Plan. The fair value of their compensation received in the form of phantom stock units is included in this

column calculated in accordance with ASC Topic 718. Ms. Piggott elected to defer the receipt of her $100,000 annual

cash retainer in her deferred cash account; and Messrs. Bunch, Darnall and Will, elected to defer all of their

compensation as phantom stock units in their respective deferred stock accounts.

(2) This column represents the grant date fair value of 2024 stock awards to directors calculated in accordance with ASC

Topic 718.

(3) Consists of amounts we contributed in 2024 to charities on behalf of directors under our matching charitable gifts

We have stock ownership guidelines for our non-employee directors where each such director is expected to own

shares of our common stock with a market value of at least five times the amount of the annual retainer, within five years

after the director joins our board. All of our current non-employee directors are in compliance with these guidelines as of

the date of this Proxy Statement.

PAY RATIO DISCLOSURE

CEO Pay Ratio
Annual Total Compensation - Current and Former CEO	$ 23,139,517
Annual Total Compensation - Median Employee	$ 90,939
Current and Former CEO to Median Employee Pay Ratio	254 :1

Supplemental CEO Pay Ratio
Annual Total Compensation - Current CEO	$ 8,840,134
Annual Total Compensation - Median Employee	$ 90,939
Current CEO to Median Employee Pay Ratio	97 :1

Our CEO pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules. For 2024, we

identified the median employee with the methodology and process as follows:

• Determined Employee Population: We began with our global employee population as of December 31, 2024,

including full-time, part-time, and seasonal or temporary workers, employed by Olin or its consolidated

subsidiaries; provided that, we applied the allowed de minimis exception to exclude 377 employees in the

following countries: China (137); Brazil (116); South Korea (35); Australia (28); Netherlands (20); Mexico (10);

Japan (7); Hong Kong (5); Taiwan (5); Russia (3); Singapore (3); Thailand (3); India (3); Denmark (1); and Turkey

(1).

• Identified the Median Employee: We calculated compensation during the 12-month period ended December 31,

2024 for each employee by using gross earnings (unreduced by any pre-tax medical or other benefits in the U.S.)

as the appropriate measure of compensation and applied the same measure for employees in the remaining non-

U.S. countries. This approach allowed us to include all elements of compensation while simplifying the process of

gathering the relevant information. It also allowed us to reasonably compare compensation for North American

employees and that of employees in multiple international locations. In calculating employee compensation of

non-U.S. employees, we averaged the month-end exchange rates for each month in 2024 and applied this

average exchange rate to the relevant foreign currencies to convert compensation to U.S. dollars. We did not

make cost-of-living adjustments and did not annualize compensation of employees hired during 2024.

Using the methodology described, we determined that the median employee for the 12-month period ended

December 31, 2024, was a full-time, hourly High Explosives Mixer in the Winchester division, working in the U.S.

• Calculated CEO Pay Ratio: For the 12-month period ended December 31, 2024, the median employee had an

annual total compensation of approximately $90,939 . We determined the annual total compensation by

calculating the elements of 2024 compensation in accordance with the requirements that apply to the Summary

Compensation Table for our NEOs. For the 2024 annual total compensation of our current and former CEO, we

used the amounts reported in the Total column of our Summary Compensation Table of $23,139,517 . For the

Supplemental CEO Pay Ratio calculation, we used our current CEO’s Summary Compensation Table reported

56

Proxy Statement Table of Contents

value, less the initial equity award of 200,000 RSUs ($11,518,000). We believe the presentation of the

Supplemental CEO Pay Ratio is a more accurate representation of CEO pay relative to the median employee as it

excludes Mr. Lane’s initial equity award which was granted to replace compensation he forfeited upon his

termination from his prior employer and induced him to join Olin.

PAY VERSUS PERFORMANCE

The following table shows the total compensation for our NEOs for the past five fiscal years as set forth in the

Summary Compensation Table (SCT), the compensation actually paid (CAP) to our CEO, and on an average basis, our

other NEOs, Olin’s total shareholder return (TSR), the TSR of our peer group (Peer Group TSR), our Net Income (Loss),

and our financial performance measure for compensatory purposes, Adjusted EBITDA . The CAP is calculated in

accordance with Item 402(v) of Regulation S-K and is subject to the adjustments contained therein which may differ

materially from our NEOs cash compensation as paid by Olin.

related volatility, changes to the length of the awards solely due to the passage of time, and updates to market

driven assumptions such as the risk-free interest rate.

(4) CAP for 2022 reflects the retirement of Mr. Dawson effective April 30, 2022 which resulted in the cancellation of his

outstanding and unvested stock option awards and pro-ration of his outstanding and unvested performance share unit

awards. Excluding the impact of Mr. Dawson’s retirement, the Average CAP in 2022 would have been $2,033,866 .

(5) TSR is determined based on the value of an initial fixed investment of $100. Our peer group reflects the performance

of the S&P 1500 Commodity Chemicals Index.

Proxy Statement Table of Contents

The measures listed above represent the most important performance measures we use to determine

compensation actually paid. Adjusted Cash Flow, Levered Free Cash Flow and Adjusted EBITDA are measures used to

assess performance against targets included in the 2024 STIP, as described in the CD&A under the heading “What We

Pay and Why: Elements of Compensation — Short-Term Incentive Program (STIP).” Net Income and Relative Total

Shareholder Return are measures used to determine achievement of performance share units under our 2024 LTIP, as

described in the CD&A under the heading “What We Pay and Why: Elements of Compensation — Long-Term Incentive

Compensation Program (LTIP).”

STOCK OPTION GRANT PRACTICES

As discussed in the CD&A above, our Compensation Committee typically approves any stock option awards at its

first committee meeting each year. In addition, our Compensation Committee’s long-standing practice is to ensure that all

stock option awards have a grant effective date at least 10 business days after the release of year-end earnings. Our

plans and policies do not permit “back dating” of options and all stock option awards must have an exercise price at least

equal to our stock’s fair market value (defined by our LTIP as the average of the high-low price on such date) as of the

grant effective date.

Olin issued a press release announcing financial results on the afternoon of January 25, 2024, after market close.

This press release contained Olin’s fourth quarter and full-year 2023 net income, adjusted EBITDA, detailed segment

information and a consolidated financial statement. Our Compensation Committee met on February 21, 2024 at which

time it approved our 2024 LTIP awards, of which 50% consisted of stock option grants. The stock option grants were

effective February 22, 2024, 19 trading days after the release of our fourth quarter and full-year 2023 earnings.

The Compensation Committee followed its customary stock option grant practices when approving these stock

option awards, which coincided with the filing of our Form 10-K Annual Report. As a result, below is specific required

information regarding these awards. We do not have a program, plan or practice of timing equity award grants in

conjunction with the release of material nonpublic information (or vice versa) . We have never re-priced or back-dated

stock options under any of our equity compensation plans and our equity plans explicitly prohibit reducing or repricing the

exercise price of stock option awards.

on February 23, 2024 was $52.59. As additional reference, the closing price of Olin’s stock on January 25, 2024,

which preceded the earnings release after market close, was $51.75. The closing stock price on January 26, 2024

was $55.15, 6.6% above the closing price prior to the earnings release.

(2) Mr. Lane’s stock options were granted in connection with his hiring as our President and CEO effective March 18,

2024, and as a result, he did not receive a stock option grant with our other NEOs on February 22, 2024. Mr. Lane’s

company.

ITEM 2—PROPOSAL TO CONDUCT AN ADVISORY VOTE TO

APPROVE THE COMPENSATION FOR NAMED EXECUTIVE OFFICERS

You are being asked to cast an advisory vote on approval of the compensation of our NEOs at the 2025 annual

meeting. This proposal, commonly known as a “say-on-pay” proposal, is required under Section 14A of the Exchange Act.

The proposal gives you the opportunity, on an advisory vote basis, to approve or not approve the compensation of our

NEOs as described in this proxy statement.

We believe that our executive compensation program is consistent with our core compensation principles and is

structured to assure that those principles are implemented. At the 2024 annual meeting of shareholders, over 96 percent

of the votes cast on this issue voted to approve the compensation of Olin’s named executive officers as disclosed in last

year’s proxy statement. Although the vote was non-binding, the Compensation Committee believes this level of approval

percentage indicates that our shareholders strongly support our core compensation principles and our executive

compensation program.

Therefore, we are submitting to shareholders the following resolution for their consideration and approval:

“RESOLVED, that the compensation paid to the Olin named executive officers, as disclosed pursuant to Item 402

of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative disclosure set

forth in the proxy statement for Olin’s 2025 annual meeting, is hereby APPROVED.”

Because your vote is advisory, it will not be binding on our Board and it will not directly affect or otherwise limit

any existing compensation or award arrangement of any of our NEOs. Our Compensation Committee does intend to take

into account the outcome of the vote when considering future executive compensation arrangements.

Vote Required for Approval

Approval of this proposal requires that more votes be cast FOR this proposal than are cast AGAINST this

proposal. Abstentions and broker non-votes will not be counted as votes cast and thus will not have any effect on the

result of the vote.

Our Board recommends a vote FOR approval of this resolution.

---

(1) Includes costs associated with the annual audit, including quarterly financial reviews, services required under

Section 404 of the Sarbanes-Oxley Act, statutory audits, comfort letters, attest services, and consents.

Our audit committee has a policy that all audit services by any independent registered public accounting firm and

all non-audit services performed by our independent registered public accounting firm are subject to pre-approval by our

audit committee at each scheduled meeting. The policy includes specific procedures for approval of such services.

Excerpts from this policy follow:

Olin’s audit committee is solely responsible for pre-approving all audit services by any independent registered

public accounting firm and all non-audit services performed by Olin’s independent registered public accounting firm. The

process for such approval is as follows:

• The annual budget for all such services will be submitted to the committee for approval in the first quarter of

each year. The budget submission will include details of actual expenditures for each audit and non-audit

service for the prior year versus the prior year budget and estimated spending for services in the current year.

The budget will also provide for certain specific services that will be pre-approved within a limited dollar range

per service. These pre-approved services are also subject to an annual spending cap.

• At each subsequent audit committee meeting, the budget will be updated for changes in estimated spending

involving previously approved services. The budget will also be updated to include any new services identified

by operations management that need to be submitted for approval.

• Any services not detailed in the budget or on the list of specific pre-approved services must be approved by

our Committee. In the event that approval is needed for a service in advance of a regularly scheduled audit

committee meeting, our Committee chair is authorized to approve the service and report such approval to the

other Committee members at the next regularly scheduled Committee meeting.

In 2024, our Audit Committee pre-approved all audit and audit-related services.

Who has our Audit Committee selected as Olin’s independent registered public accounting firm for 2025 ?

Olin’s Audit Committee is solely responsible for hiring and compensating Olin’s independent registered public

accounting firm. After considering KPMG’s 2024 performance and the fees proposed for their preliminary audit plan for

2025 , our Audit Committee has selected KPMG as our independent registered public accounting firm for 2025 .

Is a shareholder vote required to approve Olin’s independent registered public accounting firm?

Neither Virginia law nor Olin’s Bylaws require Olin to submit this matter to the shareholders at our annual meeting.

However, our Board and Audit Committee chose to submit it to the shareholders to ascertain their views.

62

Proxy Statement Table of Contents

Will I have an opportunity to hear from KPMG and ask them questions?

We expect representatives of KPMG to be present at our annual meeting. They will have an opportunity to make a

statement, if they desire to do so, and to respond to appropriate questions.

Vote Required for Ratification

To ratify the appointment of KPMG as Olin’s independent registered public accounting firm for 2025 the votes cast

FOR this proposal must exceed the votes cast AGAINST this proposal. Abstentions and broker non-votes will not be

counted as cast on this proposal and thus will not have any effect on the result of the vote.

If the shareholders’ ratification vote does not support our Audit Committee’s decision to appoint KPMG as Olin’s
