not planned a communications segment or any presentations for the 2026 annual meeting.

submitting your proxy in advance of the annual meeting.

At last year’s annual meeting more than 91% 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.

PROXY STATEMENT

________

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY

MATERIALS FOR THE 2026 ANNUAL MEETING OF SHAREHOLDERS

TO BE HELD ON APRIL 30, 2026

Olin’s Notice of the 2026 Annual Meeting of Shareholders and Proxy Statement and 2025 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 2, 2026 . 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, 3 and 4 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 20, 2026 .

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 20, 2026 .

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.

Table of Contents

What will I be voting on?

You will be voting on:

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

(2) the approval of the Olin Corporation 2026 Long Term Incentive Plan (2026 LTIP);

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

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

firm for 2026 ; and

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

Could other matters be voted on at the annual meeting?

As of March 20, 2026 , 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 Olin’s 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, 3 and 4.

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, the approval of the Olin Corporation 2026 LTIP 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 2, 2026 , 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 2, 2026 , are entitled to vote at the annual meeting.

How many votes can be cast by all shareholders?

At the close of business on March 2, 2026 , the record date for the annual meeting, we had 113,857,037

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.

• Submit the electronic proxy before the required deadline ( April 27, 2026 at 11:59 p.m. Eastern Time for

RSP participants and April 29, 2026 at 11:59 p.m. Eastern Time for all other shareholders).

• Vote by telephone:

• Call the numbers listed in the proxy materials you received.

shareholders).

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

than April 27, 2026 for RSP participants or no later than April 29, 2026 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, 2025 ?

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, 2025 , 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, 3 and 4. 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 Items 2 or 3 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 27,

2026 for RSP participants or no later than April 29, 2026 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 29, 2026 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 29, 2026 by 11:59 p.m. Eastern Time. 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 27, 2026

by 11:59 p.m. Eastern Time.

ITEM 1—PROPOSAL FOR THE ELECTION OF DIRECTORS

Who are the individuals nominated by Olin’s 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 2027 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, and Carol A. Williams to serve as directors for a one-year term expiring at

our 2027 annual meeting. All nominees are presently Olin directors who were elected by Olin shareholders at the 2025

annual meeting. Mr. Anthony Will, age 60, who has served as a member of our Board since 2021, will retire from our

Board following the completion of his current term. As a result, our Board will be reduced to eight members on the date of

the 2026 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, and Carol A. Williams as directors.

How many votes are required to elect a director?

A nominee will be elected as a director by a majority of the votes cast. A majority of the votes cast means that the

number of votes FOR a nominee must exceed the number of votes AGAINST that nominee. Abstentions and broker

shares that are not voted in the election of directors (broker non-votes) will not be included in determining the number of

votes cast and will not affect the outcome of the vote in the election of directors.

CORPORATE GOVERNANCE MATTERS

How Many Meetings Did Board Members Attend?

During 2025, our Board held five 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 2025 annual meeting participated in our 2025 annual meeting.

Which Board Members Are Independent?

Our Board has determined that each of the directors and 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. 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

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 2025, 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 2025, we purchased approximately $3,300,000 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 2025, we sold a gross aggregate of approximately $911,588 of chlor alkali products to CF Industries Holdings.

Additionally, we paid approximately $54,007,300 to Union Pacific for transportation services. One of our directors, Anthony

Will, was the President and Chief Executive Officer of CF Industries Holdings until January 2026. He is a member of the

Board of Directors of CF Industries Holdings and Union Pacific. Our Board determined that Mr. Will had no material

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

that the business relationships 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/about-olin/

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

at www.olin.com/about-olin/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

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 2, 2026 , 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 2025.

What Is Olin’s Director Nomination Process?

Our Nominating and Governance Committee acts as our nominating committee. As a policy, our Committee

considers any director candidates suggested by shareholders if we receive the appropriate information in a timely manner.

Our Committee uses the same process to review and evaluate all potential director nominees, regardless of who

recommends the candidate. Our Committee reviews and evaluates each nominee and our Committee chair and our Board

chair interview potential new Board candidates selected by our Committee. The interview results, along with our

Committee’s recommended nominees, are reviewed with our full Board.

Our Principles of Corporate Governance describe criteria for new Board members including recognized

achievement plus skills such as a special understanding or ability to contribute to some aspect of Olin’s business. Our

Committee is tasked with seeking Board members with the personal qualities and experience that taken together will

ensure a strong Board.

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 seeks candidates with a varied group

of experiences, qualifications, attributes, skills, perspectives, and backgrounds, and interviews a diverse slate of director

candidates.

This year, we h ave eight nominees s tanding 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 2027 annual meeting,

we must receive the information from shareholders on or before October 22, 2026 .

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 2027 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.

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.

Darren W. Bahr, 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 Bahr, 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 nine meetings during the year. During the second half of 2025 , 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 2025 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 2025 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, 2025 , 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”

24

Table of Contents

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

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 2025.

DELINQUENT SECTION 16(a) REPORTS

Section 16(a) of the Exchange Act requires our officers and directors, and persons who beneficially own more

than 10% of our common stock, to file reports of ownership and changes in ownership with the SEC, and these persons

must furnish us with copies of the forms they file. Officers, directors and 10% beneficial owners complied with Section

16(a) filing requirements in 2025, except as described below.

One of our officers, Kenneth T. Lane, filed one late Form 4 relating to the vesting of a restricted stock unit grant of

Olin common stock on March 18, 2025. The transaction was reported on a Form 4 which was due on March 20, 2025, but

which was filed with the SEC on July 18, 2025.

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

Introduction

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

material elements of our 2025 compensation programs for our Named Executive Officers (NEOs) as well as decisions

made by our Compensation Committee. Our NEOs for 2025 were:

Name	Title
Kenneth T. Lane	President and CEO
Todd A. Slater	Senior Vice President and CFO
Florian J. Kohl	Vice President and President, Epoxy & International
Brett A. Flaugher	Vice President and President, Winchester
Deon A. Carter	Vice President and President, Chlor Alkali Products and Vinyls

Executive Summary

Select 2025 Financial and Business Highlights

• Olin’s businesses continued to navigate a challenging industrial environment in 2025. Our Chemicals businesses

were challenged by lower product pricing and higher operating costs, which were partially offset by higher sales

volumes. Our Chlor Alkali Products and Vinyls business also experienced higher raw material costs, some of

which was offset by the qualification for and realization of clean hydrogen production tax credits under Section

45V of the Inflation Reduction Act of 2022. Our Epoxy business also experienced higher operating costs, which

were slightly offset by lower raw material costs. Our Winchester business experienced an unfavorable sales mix

as higher demand for military customer and project revenue was offset by sustained lower commercial product

demand. Winchester was also impacted by lower product pricing and higher raw material costs. Olin continued

employing a value first strategy and exercising diligence in controlling costs to deliver positive operating results

despite the challenging economic environment.

• In 2025, we began executing on our long-term value creation strategy reflected in our Optimize the Core and

Grow the Core pillars. Our Optimize the Core initiatives included our Beyond250 global operational excellence

initiative which began at our Freeport, Texas site to right-size assets and eliminate remnant costs in our

Chemicals businesses. Our Beyond250 initiative achieved $44.0 million in cost savings in 2025.

• Olin returned $142.1 million to shareholders in 2025 through share repurchases and shareholder dividends,

driven by our Levered Free Cash Flow generation in 2025 of $262.5 million.

• Our commitment to safety in 2025 resulted in no loss of life events, and the corporation’s overall injury rate was

almost 20% better year-over-year. Winchester improved its safety performance by more than 20% compared to

full year 2024. Our Chemicals business significantly improved its process safety results, cutting the number of

incidents by more than half year-over-year and making 2025 our second best year during the last five years.

• We sustained our progress toward the achievement of sustainability objectives and we are still on track to meet

our 2030 reduction goals for carbon emissions and fresh water consumption.

• Additionally, Olin employees continued to demonstrate their commitment to the communities where our plants and

offices are located by volunteering more than 56,000 hours to multiple organizations and causes.

Pay for Performance

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

Company performance objectives and shareholder value creation, each NEO has a target total direct compensation

opportunity that is reviewed annually by our Compensation Committee. As illustrated below, the majority of compensation

earned by our NEOs is linked to financial performance goals measured in our short-term incentive (STIP) and long-term

incentive (LTIP) plans. Additionally, total compensation fluctuates based on the underlying value of the common stock

granted under our LTIP.

Say on Pay Results

At the 2025 annual meeting of our shareholders, we held an advisory vote on executive compensation.

Approximately 94.3% of the shares voted were cast in support of our 2025 executive compensation and related

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

executive compensation program. Our Compensation Committee continuously evaluates our executive compensation

program and makes changes to respond to market trends and other relevant factors.

Table of Contents

Compensation Philosophy, Practices and Policies

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 2025 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 or Backdating: We prohibit option repricing without shareholder approval and do not permit backdating.
☑	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 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. We also maintain a stock ownership policy for Board of Director members which requires a multiple of 5 times the annual retainer amount to be achieved within five years from the date of joining the Board. As of December 31, 2025 , all covered executives and Board of Director members were in compliance 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 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.

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 considers 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.

Peer Group Data

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

compensation data from a peer group (referred to as the “comparator group”) that is determined and periodically adjusted,

in consultation with Exequity. 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. In 2024,

the Compensation Committee removed The Sherwin-Williams Company from the comparator group for 2025

compensation decisions due to its size relative to the Company. For 2025 compensation decisions, the comparator group

referenced by the Compensation Committee was comprised of the following 20 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	Westlake Corporation
CF Industries Holdings, Inc.	Huntsman 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. At target, 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 consists of 60% performance share units (PSUs) and 40% restricted stock units (RSUs), with the value fluctuating according to shareholder value. PSUs vest based on achievement of relative Total Shareholder Return (TSR) and Net Income. RSUs vest based on continued service.	Motivates executives to achieve long-term goals, 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), market competitive perquisites (i.e. certain insurance, financial advisory/wealth management, and health assessment benefits), 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 annually by the Compensation Committee and are adjusted based on our

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

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

Kohl, Flaugher, and Carter effective January 1, 2025 and considered but did not make any base salary adjustment for Mr.

Lane.

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 target based on our achievement with respect to pre-established

performance metrics, as discussed below. For 2025 , the target 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

target, respectively.

34

Table of Contents

For NEOs with corporate wide responsibility, Messrs. Lane and Slater, the financial targets were based entirely on

corporate performance. Corporate financial targets for 2025 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 Carter, the 80% 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 2025 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 2025 , 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 2025 STIP for each NEO.

The table below shows the 2025 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	$ 500.0	$ 1,000.0	$ 1,250.0	$ 653.3	32.7%
Levered Free Cash Flow—Corporate	$ 163.0	$ 326.0	$ 407.5	$ 262.5	24.1%
Adjusted EBITDA—Chemicals Division	$ 410.0	$ 820.1	$ 1,025.1	$ 627.9	45.9%
Adjusted Cash Flow—Chemicals Division	$ 289.2	$ 578.4	$ 723.0	$ 637.8	30.4%
Adjusted EBITDA—Winchester Division	$ 156.5	$ 313.1	$ 391.4	$ 103.4	—%
Adjusted Cash Flow—Winchester Division	$ 119.0	$ 238.1	$ 297.6	$ 46.5	—%

For 2025 , in calculating Adjusted EBITDA, we used 2025 EBITDA excluding the effect of the following special

charges, gains and losses (which were reflected in our 2025 EBITDA): (i) restructuring charges of $33.4 million, (ii) a $1.5

million adjustment related to a previously completed acquisition, and (iii) environmental insurance recoveries for costs

incurred and expensed in prior years of $1.0 million.

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

applied to 20% of the 2025 STIP for each NEO. After reviewing performance, as discussed below, the Compensation

Committee determined all applicable NEOs earned 18.0% of their target STIP award based on non-financial performance

in the aggregate.

Non-Financial Category	Percentage Earned
Strategic Goals	14.0%
Safety, Health & Environmental Goals	4.0%

Table of Contents

STIP Opportunities and Payments. The STIP opportunities and payouts for 2025 were as follows:

NEO	Threshold	Target	Maximum	Earned
Kenneth T. Lane	$ 572,000	$ 1,430,000	$ 2,860,000	$ 1,069,640
Todd A. Slater	$ 260,000	$ 650,000	$ 1,300,000	$ 486,200
Florian J. Kohl	$ 190,000	$ 475,000	$ 950,000	$ 424,769
Brett A. Flaugher	$ 224,000	$ 560,000	$ 1,120,000	$ 180,320
Deon A. Carter	$ 200,000	$ 500,000	$ 1,000,000	$ 447,125

Long-Term Incentive Program (LTIP)

For 2025 , the Compensation Committee set the following target LTIP award levels which were allocated between

PSUs (60%) and RSUs (40%). The change in mix from equal allocation between PSUs and stock options for the LTIP

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

Compensation Committee’s belief that RSUs are less dilutive to shareholders and, as full value awards, more strongly

incentivize executive retention. The Compensation Committee did not award stock options to NEOs in 2025.

NEO	Target Award
Kenneth T. Lane	$ 7,500,000
Todd A. Slater	$ 1,800,000
Florian J. Kohl	$ 1,250,000
Brett A. Flaugher	$ 1,300,000
Deon A. Carter	$ 1,400,000

Performance Share Units. Each NEO’s 2025 LTIP target award value was delivered 60% in performance share

units (PSUs). The target number of PSUs awarded to each NEO was determined by dividing 60% of 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 2025 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 differs from the targeted value due to the accounting rules under

Accounting Standards Codification Topic 718, Compensation—Stock Compensation (ASC 718).

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

December 31, 2027 compared to the community of companies in the S&P 1500 Materials 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

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 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 versus 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.

Restricted Stock Units. The remaining 40% of each NEO’s 2025 LTIP target award value is delivered in RSUs.

The number of RSUs awarded to each NEO is determined by dividing 40% of 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 RSUs vest in three, equal annual installments, generally contingent on the NEO’s

continued employment.

Dividend Equivalents. Dividend equivalents for PSUs and RSUs accrue throughout the relevant vesting period

based on the underlying number of PSUs or RSUs granted to the NEO. Dividend equivalents are based on the amount of

common stock dividends declared and paid on our common stock and only vest upon the satisfaction of the underlying

award vesting criteria.

2023 PSU Award. In February 2023, as part of our annual LTIP award cycle, our Compensation Committee

granted PSU awards to Messrs. Slater and Flaugher, both of whom were 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 2023 through 2025. Our relative TSR percentile ranking for the 2023 through 2025 performance period was

4.83% as compared to our Performance Share Comparison Group resulting in a vesting at 0.00% for the relative TSR

PSU portion. Our net income performance was 60.47% for 2023, 0.00% for 2024, 0.00% for 2025, and 0.00% for the

2023 to 2025 cumulative period resulting in an aggregate payout percentage of 12.10% for the net income PSU portion.

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

under their 2023 PSU awards:

NEO	Target PSUs	PSUs Aggregate Payout %	PSUs Earned
Todd A. Slater	13,626	6.05%	825
Brett A. Flaugher	7,846	6.05%	475

Other Compensation

We offer a small number of other personal benefits, such as certain insurance, financial advisory/wealth

management, and health assessment benefits to our NEOs, and the retirement and severance 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

37

Table of Contents

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, 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 plan and two nonqualified plans, the Senior and

Supplemental Plans. Messrs. Slater and Flaugher 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 heading “Potential Payments Upon Termination or Change in Control.”

Looking Forward to 2026

Our Compensation Committee conducted an evaluation of the performance measures utilized as part of the PSU

awards. Based on that evaluation, beginning in 2026, the PSU awards will include a performance measure based on

Adjusted EBITDA with a performance multiplier based on Olin’s TSR. The Compensation Committee believes this change

will more closely align the long-term interests of our NEOs with those of shareholders and better align our performance

with the cyclical nature of the businesses in which we operate.

Risk Assessment

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

compensation programs. In November 2025, 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.

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

under the Qualified Plan and Supplemental Plan. Other than Messrs. Slater and Flaugher, 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. Please see the note entitled

“Pension Plans” in the notes to our audited financial statements included in our 2025 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, the first age at which unreduced pension benefits are

payable under the applicable Plans.

(5) Amounts reported in this column for 2025 are comprised of the following items:

NEO	Retirement Account Contributions (1)	Perquisites and Personal Benefits (2)	Other Payments (3)	Total

(1) 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 NEO contributes

to each plan.

(2) The amounts shown represent the costs associated with providing financial advisory/wealth management, life

insurance, excess liability insurance, and underinsured and uninsured motorist insurance to the NEO.

(3) The amounts shown represent moving allowances paid in connection with relocation to Olin’s office in Houston,

Texas.

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

Our NEOs are not employed under general employment contracts. See “What We Pay and Why: Elements of

Compensation” in the CD&A above for a discussion of the material terms of our 2025 STIP and LTIP. 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

equity awards.

Retention Agreements with Certain NEOs. In light of the pending CEO transition, on December 20, 2023, the

Company entered into retention agreements (each, a "Retention Agreement”) with Messrs. Slater, Kohl, and Flaugher,

which provided the opportunity to earn a $1,000,000 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

Retention Agreements included restrictive covenants, including non-competition, non-solicitation, and confidentiality

protections in favor of Olin.

The NEOs vested in 50% of their retention bonus in 2025 based on continued employment through July 1, 2025

and vested in the remaining 40% of the Retention Bonuses on January 1, 2026, which were subsequently paid in January

2026.

(1) Amounts in these columns represent the potential annual cash incentives established under our 2025 STIP, as

described in the CD&A under the heading “What We Pay and Why: Elements of Compensation – Short-Term Incentive

Program.” Actual amounts were determined, approved, and paid in early 2026 , and are included in the Non-Equity

Incentive Compensation column of the Summary Compensation Table.

(2) For all NEOs, numbers in these columns represent awards of PSUs under our 2025 LTIP, as described in the CD&A

under the heading “What We Pay and Why: Elements of Compensation – Long-Term Incentive Program (LTIP),”

which vest based on achievement of three-year performance goals related to relative TSR and net income. The

amounts in column (h) represent 200% of the target amounts.

(3) For all NEOs, numbers in this column represent awards of RSUs under our 2025 LTIP, as described in the CD&A

under the heading “What We Pay and Why: Elements of Compensation – Long-Term Incentive Program (LTIP),”

which vest in three, equal annual installments, generally contingent on the NEO’s continued employment.

(4) Amounts in this column assume payment of PSUs at the target level and RSUs fully vest, in each case calculated in

accordance with ASC 718. Please see the note entitled “Stock-Based Compensation” in the notes to our audited

(1) The shares listed in column (d) above represent PSUs paid in February 2025 (vested based on our performance for

the three years ended December 31, 2024 ), under an award made in early 2022 , resulting in net shares delivered to

Messrs. Slater and Flaugher of 3,482 and 1,845, respectively, after 3,483 and 1,846 shares, respectively, were paid in

cash. In addition, the shares listed in column (d) above also includes (i) an RSU award granted on March 18, 2024

under which the first tranche vested on March 18, 2025 for Mr. Lane, resulting in 35,317 net shares delivered after

14,683 shares were withheld for taxes, (ii) an RSU award granted on June 1, 2024 under which the first tranche

vested on June 1, 2025 for Mr. Kohl, resulting in 945 net shares delivered after 305 shares were withheld for taxes,

and (iii) an RSU award granted on June 18, 2024 under which the first tranche vested on June 18, 2025 for Mr. Carter,

resulting in 1,891 net shares delivered after 609 shares were withheld for taxes.

(2) PSUs are paid approximately half in cash and half in stock. The cash portion of the PSUs payment was based on the

fair market value of the shares as of December 31, 2024 ($33.54), 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 19, 2025 , the date the shares were issued ($27.61). RSUs are valued based on

the average of the high and low sales price of our common stock on the vesting date. The value in this column also

includes dividend equivalents paid on the gross number of shares which vested.

Pension Benefits

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

2025 , for Messrs. Slater and Flaugher. 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 2025 annual report on Form 10-K for a discussion of these assumptions.

Brett A. Flaugher (4)	Qualified Plan	23.37	$ 834,320	$ —
	Supplemental Plan	23.37	$ 32,609	$ —

(1) For Messrs. Slater and Flaugher, benefit accruals were frozen under all 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.

(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. The

assumptions we used for financial reporting as of December 31, 2025 , including a 5.4% single effective rate (in lieu of

a discount rate) for the Qualified Plan, a 4.9% single effective rate for the Supplemental Plan, a 4.8% single effective

rate for the Senior 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 (a “single life annuity”) or payments continuing after the executive’s death

for the life of his or her spouse (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. The Senior Plan generally provides a 50% joint and survivorship benefit without any

actuarial reduction, and also provides the executive with an additional amount equal to the amount of the actuarial

reduction of benefits payable from the Qualified Plan and the Supplemental Plan for a 50% joint and survivorship

benefit election.

(4) All accrued benefits under the Supplemental Plan and Senior 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 Payments). At the time of the Acquisition, Messrs. Slater and Flaugher had not reached retirement age, so

they have residual benefits under the Supplemental Plan and Mr. Slater has a residual benefit under the Senior Plan.

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 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. For, participants who are at least age 55, but younger than age 62 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 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.

45

Table of Contents

Supplemental and Senior Plans

The Supplemental Plan and Senior Plans are frozen unfunded, nonqualified deferred compensation plans 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.

Under the Senior Plan, participating employees who were Section 16(b) Officers selected by our committee prior

to the freeze date receive pension benefits generally equal to 3% of the executive’s average eligible compensation (not

subject to the Code and other Qualified Plan limits) multiplied by the number of years of participation in the Senior Plan,

plus 1.5% of the executive’s average compensation for years of service in the Qualified Plan and Supplemental Plan, less

years of service in the Senior Plan, reduced by the pension benefits accrued under the Qualified Plan and the

Supplemental Plan. Senior Plan benefits are further reduced by 50% of the employee’s primary Social Security benefit.

The Senior Plan provides a joint and survivorship benefit to an executive’s surviving spouse, generally equal to 50% of the

executive’s benefits from the Senior Plan. In addition, the Senior Plan pension benefits are increased by the amount of

the actuarial reduction to benefits under the Qualified and Supplemental Plans if the executive elects the 50% joint and

survivorship option under those plans.

As noted above, previously accrued benefits in the Supplemental and Senior Plans 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 the Supplemental

Plan and Mr. Slater has a residual benefit under the Senior Plan 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 NEO’s 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 2025 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.

Additionally, the value of benefits for Mr. Slater under the Senior Plan is disclosed under the heading “Pension Benefits”

above and would be applicable in the case of a termination by Olin without cause not in connection with a change in

control and retirement prior the age of 65. 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.

A summary of the benefits available on December 31, 2025 in different scenarios under the terms of our

Executive Severance Plans, 2025 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

47

Table of Contents

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 when STIP is payable to other employees of Olin;

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

year of termination based on the executive’s target annual cash incentive opportunity for the year of termination,

payable in a lump sum;

• outplacement services for a period of up to twelve months

Change in Control not in Connection with a Termination

• for awards issued in 2024 or prior: vesting and payment of unvested PSU awards at target levels;

• for awards issued in 2025 or after: continued vesting if award assumed by the acquiring corporation;

• vesting of any unvested RSU awards at target level if not assumed or substituted by the acquiring corporation;

Tabular Disclosure

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

2025 , upon various triggering events (assuming the event occurred on December 31, 2025 ). 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, 2025 . 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.

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 2025 , the Board approved the following cash fees and equity compensation:

Element of Compensation	Amount	Election
Annual Stock Grant	$ 140,000	(1)
Annual Retainer - Stock	$ 60,000	(2)
Annual Retainer - Cash	$ 100,000	(3)
Additional Lead Director Retainer	$ 35,000	(3)
Additional Nominating and Governance Committee Chair Retainer	$ 20,000	(3)
Additional Compensation Committee Chair Retainer	$ 25,000	(3)
Additional Audit Committee Chair Retainer	$ 30,000	(3)
Additional Non-Executive Board Chair Retainer	$ 150,000	(3)
Election: (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).

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.

51

Table of Contents

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

2025 . Mr. Lane did not receive any additional compensation for his service as a director.

(1) While C. Robert Bunch served as a member of our Board until April 30. 2025, his name does not appear in this table

as he did not earn or receive any reportable compensation during 2025.

(2) Messrs. Darnall, Shipp 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 718. Ms. Piggott elected to defer the receipt of her $100,000 annual cash retainer in her

deferred cash account, Mr. Shipp elected to defer his Compensation Committee Chair Fee as phantom stock units in

his deferred stock account, and Messrs. Darnall and Will, elected to defer all of their compensation as phantom stock

units in their respective deferred stock accounts. Mr. Daly joined the Board on March 6, 2025, during the final two

months of the 2024 compensation period. Accordingly, he received a pro-rated amount of the 2024 director

compensation for his service from March 6, 2025 through April 30, 2025. Beginning May 1, 2025, Mr. Daly became

eligible for the full annual compensation for the 2025 compensation period.

(3) This column represents the grant date fair value of stock awards to directors calculated in accordance with ASC 718.

(4) Consists of $5,000 contributed to charities on behalf of Mses. Piggott and Williams and Mr. Weideman under our

matching charitable gifts program available to all directors.

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 - CEO	$ 9,798,424
Annual Total Compensation - Median Employee	$ 98,383
CEO to Median Employee Pay Ratio	100 :1

Our CEO pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules. For 2025 , 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, 2025 ,

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 371 employees in the following countries:

China (119); Brazil (104); Italy (49); Australia (29); Netherlands (19); Switzerland (16); Mexico (13); Japan (6); South

Korea (3); Taiwan (3); Hong Kong (2); India (2); Russia (2); Thailand (2); Denmark (1); and Turkey (1).

• Identified the Median Employee: We calculated compensation during the 12-month period ended December 31,

2025 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 2025 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 2025 .

Using the methodology described, we determined that the median employee for the 12-month period ended

December 31, 2025 , was a full-time, hourly Process Operator in the Chemicals division, working in the U.S.

• Calculated CEO Pay Ratio: For the 12-month period ended December 31, 2025 , the median employee had an

annual total compensation of approximately $98,383 . We determined the annual total compensation by calculating

the elements of 2025 compensation in accordance with the requirements that apply to the Summary Compensation

Table for our NEOs. For the 2025 annual total compensation of our CEO, we used the amounts reported in the Total

column of our Summary Compensation Table of $9,798,424 .

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, our other NEOs on an average

basis, Olin’s total shareholder return (TSR), the TSR of our peer group (Peer Group TSR), our Net (Loss) Income, 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.

Total Adjustments for Equity Awards	( 6,309,830 )	( 915,461 )
Compensation Actually Paid	$ 3,488,594	$ 2,059,328

(i) Our valuation assumptions used to calculate the fair value of equity awards reflect changes in our stock price and

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 PSU 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.

ITEM 2—PROPOSAL TO APPROVE THE

OLIN CORPORATION 2026 LONG TERM INCENTIVE PLAN

Our Board recommends that shareholders approve the Olin Corporation 2026 Long Term Incentive Plan (the 2026

LTIP), to succeed the Olin Corporation 2021 Long Term Incentive Plan (2021 LTIP), the Olin Corporation 2018 Long Term

Incentive Plan (2018 LTIP), the Olin Corporation 2016 Long Term Incentive Plan (2016 LTIP), the Olin Corporation 2014

Long Term Incentive Plan (2014 LTIP), the Olin Corporation 2009 Long Term Incentive Plan (2009 LTIP), the Olin

Corporation 2003 Long Term Incentive Plan (2003 LTIP), and the 1997 Stock Plan for Non-Employee Directors (1997

Plan), and collectively the 2021 LTIP, 2018 LTIP, 2016 LTIP, 2014 LTIP, 2009 LTIP, 2003 LTIP, and 1997 Plan, the Prior

Plans.

The Prior Plans are the only long-term incentive plans under which equity-based awards can currently be granted

to our executives, employees, and non-employee directors (collectively, Prior Plan Participants). On February 19, 2026,

upon the recommendation of the Compensation Committee, the Board unanimously approved and adopted the 2026 LTIP,

subject to approval by our shareholders. If the 2026 LTIP is approved, shares that remain available under the Prior Plans

will be cancelled. If the 2026 LTIP is not approved by our shareholders, the Prior Plans will remain in effect in their current

form and will continue to be used to grant equity incentive awards under the Prior Plans until their expiration.

A summary of the principal features of the 2026 LTIP is below. This summary does not purport to be complete and

is subject to, and qualified in its entirety by, the 2026 LTIP. The full plan is set forth in Appendix A to this proxy statement.

The aggregate number of shares being requested for authorization under the 2026 LTIP is 4,500,000.

Purpose

The general purposes of the 2026 LTIP are to attract and retain persons eligible to participate in the 2026 LTIP,

motivate participants with appropriate incentives to achieve long-range goals, provide incentive compensation

opportunities that are competitive with those of other similar companies, and further align participants’ interests with those

of other shareholders of Olin through compensation that is tied to the value of Olin’s common stock; thereby promoting the

long-term financial interest of Olin, including sustained growth in the value of Olin’s equity and enhancement of long-term

shareholder return.

Long Term Incentive Plan Information

In connection with the design and adoption of the 2026 LTIP, our Board and Compensation Committee carefully

considered our anticipated future equity needs and our historical equity compensation practices. As of March 2, 2026,

there were 4,333,418 shares available to grant to Prior Participants under the Prior Plans, all of which plans will be

cancelled if the 2026 LTIP is approved.

Our Board recognizes the impact of dilution on our shareholders and has evaluated the proposed share request

carefully in the context of the need to motivate, retain and ensure that our 2026 LTIP participants are focused on our

strategic priorities. The total fully-diluted overhang calculated with inputs as of March 2, 2026 was calculated as follows:

Total Granted Shares Outstanding	6,475,722
Shares Available for Future Awards Under 2026 LTIP	4,500,000
Total Shares Outstanding and Available (A)	10,975,722
Basic Common Shares Outstanding (B)	113,857,037
Fully-Diluted Overhang (A/B)	9.6 %

Our Board believes that the proposed share reserve represents a reasonable amount of potential equity dilution to

accommodate our long-term strategic and growth priorities.

We expect that the share reserve under the 2026 LTIP, if this proposal is approved by our shareholders, will be

sufficient for equity awards for approximately three years. Expectations regarding future share usage could be impacted

by a number of factors including, but not limited to, (i) the future performance of our stock price, (ii) the equity award types

granted and mix, (iii) the rate at which shares are recycled into the 2026 LTIP as allowable under the 2026 LTIP, and (iv)

award activity at the participant level resulting from new hires, promotions, etc. While we believe that the assumptions we

used are reasonable, future share usage may differ materially from current expectations.

If the 2026 LTIP is approved by our shareholders, the 2026 LTIP will replace the Prior Plans, and the Company

will cease granting any new awards under the Prior Plans. If the Plan is not approved by our shareholders, the Prior

Plans will remain in effect in their current form, and the Company will continue to grant equity incentive awards under the

Prior Plans until their expiration. If shareholders do not approve the 2026 LTIP, we will be unable to maintain our current

equity grant practices and, therefore, will be at a significant competitive disadvantage in attracting, retaining and

motivating talented participants who contribute to Olin’s long term success. The Company will also be compelled to

consider replacing equity incentive awards with cash awards, which may not align the interests of participants with our

shareholders as effectively as equity incentive awards.

Share Authorization

The maximum number of shares of common stock that may be subject to awards granted under the 2026 LTIP will

not exceed 4,500,000 shares of common stock.

If any shares are forfeited, cancelled, expire or otherwise terminate, or such award is settled for cash (in whole or

in part) (including with respect to any awards outstanding under a Prior Plan as of the 2026 LTIP effective date), the

shares subject to such award shall, to the extent of such forfeiture, cancellation, expiration, or cash settlement, be

available for future grants of awards under the 2026 LTIP. In addition, other than in the case of any option or stock

appreciation right, shares tendered by a participant or withheld by Olin to satisfy any tax withholding obligation (including

with respect to any awards outstanding under a Prior Plan as of the 2026 LTIP effective date) shall be available for future

grants of awards under the 2026 LTIP. For the avoidance of doubt, the following Shares shall not be available for future

grants of awards under the 2026 LTIP: shares (i) tendered by a participant or withheld by Olin to satisfy any tax

withholding obligation on any option or stock appreciation right (including with respect to any awards outstanding under a

Prior Plan as of the 2026 LTIP effective date), (ii) tendered by a participant or withheld by Olin to satisfy any exercise price

payment (including with respect to any awards outstanding under a Prior Plan as of the 2026 LTIP effective date), or (iii)

purchased using proceeds received as payment for any exercise price. The payment of dividend equivalents in cash in

conjunction with any outstanding awards shall not be counted against the shares available for issuance under the 2026

LTIP.

In the event the Compensation Committee determines that, as a result of any stock split, reverse stock split, stock

dividend, recapitalization, combination of shares, reclassification of shares, spin-off, any reorganization or other similar

change in capitalization or event, or any distribution to holders of common stock other than a normal cash dividend, or of

changes in applicable laws, regulations or accounting principles, an adjustment is necessary to prevent dilution or

enlargement of the benefits or potential benefits intended to be made available under the 2026 LTIP, the Compensation

58

Table of Contents

Committee will adjust equitably any or all of: (i) the number equity awards available under the 2026 LTIP; (ii) the number

and/or price of shares of common stock subject to outstanding awards granted under the 2026 LTIP; (iii) the repurchase

price per share subject to each outstanding restricted stock unit; (iv) the grant, acquisition, or exercise price with respect

to any award or, if deemed appropriate, make provision for a cash payment to the holder of an outstanding award and (v)

the terms and conditions of any outstanding awards, including the performance criteria of any performance awards.

Eligibility

Awards under the 2026 LTIP may be granted to employees, non-employee directors, and other eligible service

providers, such as consultants and advisors, as determined by our Compensation Committee or its authorized delegates.

Governance

The 2026 LTIP incorporates corporate governance best practices to align our equity compensation program with

the interests of our shareholders, including:

☑	Maintain a Clawback Policy: The Compensation Committee has the authority to subject awards granted under the 2026 LTIP to any clawback or recoupment policies.	☒	No Option Repricing: Repricing of stock options and stock appreciation rights awards is not permitted without stockholder approval, except for adjustments with respect to certain specified extraordinary corporate transactions.
☑	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. We also maintain a stock ownership policy for Board of Director members which requires a multiple of 5 times the annual retainer amount to be achieved within five years from the date of joining the Board.	☒	No Reload of Options or Stock Appreciation Rights: The 2026 LTIP does not permit the use of reload options or stock appreciation rights which provide that the exercise of a stock option or stock appreciation right can automatically trigger the grant of a new stock option or stock appreciation right.
☑	Dividends and Dividend Equivalents: The 2026 LTIP subjects dividends and dividend equivalents to the same vesting restrictions, including any service and performance conditions, as the underlying award and does not allow for payment prior to these conditions being met.	☒	No Tax Gross-Ups: No participant is entitled under the 2026 LTIP to any tax gross-up payments for any excise tax pursuant to Sections 280G or 4999 of the Code that may be incurred in connection with awards under the 2026 LTIP.
		☒	No Evergreen Provisions: The 2026 LTIP does not contain an evergreen feature pursuant to which the shares authorized for issuance under the plan can be increased automatically without stockholder approval.
		☒	No Hedging or Pledging: We do not allow our NEOs to hedge or pledge our stock.
		☒	No Liberal Option Share Recycling: The 2026 LTIP only allows option share recycling to the extent the award is forfeited, cancelled, expires or otherwise terminates without exercise of the underlying award.
		☒	No Liberal Change-in-Control Provisions: The change-in-control definition under the 2026 LTIP is only triggered in those instances where an actual change-in-control occurs.

Award Limits

A participant who is a non-employee director may not receive compensation in the aggregate, including cash

59

Table of Contents

payments and awards, in excess of $750,000 during each calendar year while serving in such capacity. Any

compensation granted, paid or awarded for services other than as a non-employee director (including as an officer,

employee or consultant of the Company or its affiliates) shall not count towards such limit.

Administration

Our Board designated the Compensation Committee as the administrative committee for the 2026 LTIP. Our

Compensation Committee has full authority to interpret the 2026 LTIP, determine eligibility for awards, and adopt such

rules, forms, and guidelines as it deems necessary or advisable to administer the 2026 LTIP. Each member of our

Compensation Committee must be (i) a non-employee director for purposes of Rule 16b-3 under the Exchange Act and (ii)

independent under the NYSE listing criteria. Our Board also may elect to take any action under the 2026 LTIP that would

otherwise be the responsibility of our Compensation Committee. Our Compensation Committee may delegate partial or

full authority to one or more members of Olin’s management under the 2026 LTIP with respect to eligible employees who

are not officers for purposes of Section 16(b) of the Exchange Act.

Subject to the terms and conditions of the 2026 LTIP, our Compensation Committee has the authority to select the

employees to whom awards are to be made, determine the number of shares to be subject to awards, determine the

terms and conditions of awards, and make all other determinations and take other actions necessary or advisable for the

administration of the 2026 LTIP, including termination of such awards. Our Compensation Committee may at any time

suspend or terminate the 2026 LTIP.

Award Types

The 2026 LTIP provides that the Compensation Committee will specify the type, terms and conditions of the

award. Each award may be set forth in a separate agreement with the person receiving the award. The 2026 LTIP allows

for grants of stock options, both in the form of nonqualified stock options (NQSOs) or incentive stock options (ISOs), stock

appreciation rights, restricted stock, restricted stock units, performance share units, other stock based awards, and cash

bonus awards.

Stock Options. A stock option is a contractual right to purchase shares at a future date at a specified exercise

price. The per share exercise price may not be less than the fair market value on the date of grant, which, unless our

committee determines otherwise, is the average of the high and low sales prices per share of Olin common stock as

reported on the NYSE as of the grant date. The Compensation Committee will determine the date after which each stock

option may be exercised and the expiration date of each stock option, provided that no stock option will be exercisable

more than ten years after the grant date. Stock options that are intended to qualify as ISOs must meet the requirements

of Section 422 of the Code.

Stock Appreciation Rights. A stock appreciation right represents a contractual right to receive, in cash or

shares, an amount equal to the appreciation of one share from the grant date. Any stock appreciation rights will be

granted subject to the same terms and conditions as apply to NQSOs.

Restricted Stock. Restricted stock refers to stock that is subject to risk of forfeiture or other restrictions as our

committee determines. Such restrictions will lapse under such circumstances as our committee may determine, including

upon the achievement of performance criteria. In general, restricted stock may not be sold, or otherwise transferred or

hypothecated, until the restrictions (if any) are removed or expire. Recipients of restricted stock may have voting rights as

determined by the Compensation Committee.

Restricted Stock Units. A restricted stock unit entitles the holder to receive shares of Olin common stock or

cash at the end of a specified deferral period but does not entitle the holder to any voting rights.

Performance Share Units. Performance share units provide for future issuance of shares to the recipient upon

the attainment of corporate performance goals established by the Compensation Committee over specified performance

periods. Prior to payment of performance shares, the Compensation Committee will certify that the performance

objectives were satisfied. Performance objectives may vary from individual to individual and will be based upon one or

more performance criteria the Compensation Committee may deem appropriate, including the criteria described above.

60

Table of Contents

Cash Bonus Awards. The Compensation Committee may make certain cash bonus awards under the 2026

LTIP. Any such Award may be subject to a performance period, performance goals or such other terms and conditions as

the Compensation Committee may designate in the applicable award agreement.

Other Stock Based Awards. The Compensation Committee may make other stock based awards in such

amounts and subject to such terms and conditions as the Compensation Committee shall determine.

Termination of Service and Change in Control

The Compensation Committee shall determine the treatment of any outstanding awards in the event of a

participant’s termination of employment or service prior to the completion of the applicable performance period or vesting,

exercise, or settlement date. Such determination shall include without limitation, whether any outstanding awards will vest,

become exercisable, settle, be paid, or be forfeited. Termination of service generally results in the application of standard

termination provisions of the associated equity awards; however, our Compensation Committee does retain discretion to

apply continuation provisions consistent with the underlying circumstances and relevant business need.

The 2026 LTIP provides that a change in control means any of the following, provided that the following

constitutes a change in the ownership or a change in the effective control of Olin or a change in the ownership of a

substantial portion of Olin’s assets within the meaning of Code Section 409A:

i. The acquisition by one person, or more than one person acting as a group, of ownership of stock (including

Shares) of Olin that, together with stock held by such person or group, constitutes more than 50% of the total

fair market value or total voting power of the stock of Olin. Notwithstanding the above, if any person or more

than one person acting as a group, is considered to own more than 50% of the total fair market value or total

voting power of the stock of Olin, the acquisition of additional stock by the same person or persons will not

constitute a Change in Control; or

ii. A majority of the members of Olin’s Board of Directors is replaced during any 12-month period by directors

whose appointment or election is not endorsed by a majority of the members of Olin’s Board of Directors

before the date of the appointment or election; or

iii. The sale, transfer or other disposition of all or substantially all of the business or assets of Olin.

Persons will not be considered to be acting as a group solely because they purchase or own stock of the same

corporation at the same time, or as a result of the same public offering. However, persons will be considered to

be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or

acquisition of stock, or similar business transaction with Olin.

In the event of a Change in Control, the Compensation Committee may in its discretion, cancel any outstanding

vested Awards and pay to the holders thereof, in cash or stock, or any combination thereof, the value of such vested

awards based upon the price per share received or to be received by other shareholders of Olin upon such change in

control. The surviving, continuing, successor, or purchasing corporation or other business entity or parent thereof, as the

case may be (the Acquiror), may, without the consent of any participant, assume or continue Olin’s rights and obligations

under each or any award or portion thereof outstanding immediately prior to the change in control or substitute for each or

any such outstanding Award or portion thereof a substantially equivalent award with respect to the Acquiror’s stock, as

applicable. If so determined by the Compensation Committee in its discretion, an award denominated in shares shall be

deemed assumed if, following the change in control, the award confers the right to receive, subject to the terms and

conditions of the 2026 LTIP and the applicable award agreement, for each share subject to the award immediately prior to

the change in control, the consideration (whether stock, cash, other securities or property or a combination thereof) to

which a holder of a share on the effective date of the change in control was entitled (and if holders were offered a choice

of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares); provided,

however, that if such consideration is not solely common stock of the Acquiror, the Compensation Committee may, with

the consent of the Acquiror, provide for the consideration to be received upon the exercise or settlement of the award, for

each share subject to the award, to consist solely of common stock of the Acquiror equal in fair market value to the per

share consideration received by holders of shares pursuant to the change in control.

Unless otherwise specified in the applicable award agreement or policies adopted by the Compensation

Committee, (i) any award or portion thereof which is not assumed, continued or substituted as provided herein by the

Acquiror in connection with the change in control, irrespective of the vesting schedule, shall become fully vested (with any

61

Table of Contents

performance conditions considered achieved at target levels) and immediately exercisable and, if applicable, the restricted

period shall end as of the time of consummation of the change in control and (ii) any award or portion thereof which is

assumed, continued or substituted as provided herein by the Acquiror in connection with the change in control,

irrespective of the vesting schedule, shall become fully vested (with any performance conditions considered achieved at

target levels) and immediately exercisable and, if applicable, the restricted period shall end as of the time of

consummation of the change in control upon a participant’s qualifying termination.

In the event any payment(s) or the value of any benefit(s) received or to be received by a participant in connection

with or contingent upon a change in control (whether received or to be received pursuant to the terms of the Plan or any

award agreement or of any other plan, arrangement or agreement of Olin, its successors, any person whose actions result

in a change in control, or any person affiliated with any of them (or which, as a result of the completion of the

transaction(s) causing a change in control, will become affiliated with any of them) (collectively, the Payments)), are

determined, under the provisions of this subsection to be subject to an excise tax imposed by Code Section 4999 (any

such excise tax, together with any interest and penalties, are hereinafter collectively referred to as the Excise Tax), as

determined in this subsection, then Olin shall reduce the aggregate amount of the Payments payable to the participant

such that no Excise Tax shall be payable by the participant and the Payments shall not cease to be deductible by Olin by

reason of Code Section 280G (or any successor provision thereto). Notwithstanding the foregoing, Olin shall not reduce

the aggregate amount of the Payments payable to the Participant pursuant to the foregoing sentence if the After-Tax

Amount (as defined below) of the unreduced Payments is greater than the After-Tax Amount that would have been paid

had the Payments been reduced pursuant to the foregoing sentence. For purposes of this agreement “After-Tax Amount”

means the portion of a specified amount that would remain after payment of all Excise Taxes (if any), income taxes,

payroll and withholding taxes, and other applicable taxes paid or payable by participant in respect of such specified

amount. Any reductions shall be made in a manner intended to comply with Section 409A of the Code.

Term, Amendment, and Termination

The 2026 LTIP shall remain in effect until the tenth anniversary of the 2026 LTIP effective date. The

Compensation Committee may amend, suspend, discontinue or terminate the 2026 LTIP at any time; provided that, (i) no

amendment that would require approval of Olin’s shareholders under any applicable law, regulation or rule, including the

rules of any stock exchange or quotation system upon which the shares may then be listed or quoted shall be made

without obtaining such shareholder approval and (ii) no amendment, suspension, discontinuance or termination may apply

to the terms of any outstanding Award (contingent or otherwise) granted prior to the effective date of such amendment,

suspension, discontinuance or termination, in a manner which would reasonably be considered to be adverse to the

participant, without the participant’s consent. In the event of a Plan termination, the 2026 LTIP shall remain in effect as

long as any awards under it are outstanding.

U.S. Federal Income Tax Consequences

The following discussion provides a general summary of the U.S. federal income tax consequences generally

arising with respect to awards under the 2026 LTIP. This summary provides general tax principles that apply to awards

granted to U.S. participants and citizens and is provided only for general information. Certain taxes, such as foreign, state

and local income taxes, payroll taxes and the alternative minimum tax, are not discussed. This summary is not tax advice

and it does not discuss all aspects of U.S. federal taxation that may be relevant to Olin and participants. Accordingly,

participants should consult a tax advisor as to the specific tax consequences of participation in the 2026 LTIP.

Stock Options. The grant of a NQSO is not a taxable event either for the optionee or for Olin. Upon exercise of

a NQSO, the optionee will recognize ordinary income in an amount equal to the excess of the fair market value of the

shares of Olin common stock acquired upon exercise, determined at the date of exercise, over the exercise price of such

option. Olin will be entitled to a business expense deduction equal to such amount, subject to the limitations imposed by

Code Section 162(m).

An optionee recognizes no taxable income upon the grant or exercise of an ISO, although payment of the option

price with shares of Olin common stock may result in taxable income on the transfer of the shares. The payment in

shares will not affect the favorable tax treatment of the Olin common stock received as a result of exercising the option. If

an optionee meets the various holding period requirements, any gain or loss on the subsequent disposition of such Olin

common stock will be taxed to the optionee as long-term capital gain or loss, and Olin will not be entitled to a deduction.

To the extent that an optionee recognizes ordinary income by reason of failing to meet those requirements, Olin will be

entitled to a corresponding business expense deduction, subject to the limit imposed by Code Section 162(m).

62

Table of Contents

Restricted Stock and Restricted Stock Units. A holder of restricted stock generally will recognize ordinary

income in an amount equal to the fair market value of the Olin common stock upon lapse of the restrictions. A holder of

restricted stock units generally will recognize ordinary income in an amount equal to the fair market value of the Olin

common stock upon issuance of the shares (or upon receipt of the cash payment, in an amount equal to the cash

payment, if the restricted stock units are settled in cash). Subject to the limit imposed by Code Section 162(m), Olin is

entitled to a business expense deduction that corresponds to the amount of ordinary income recognized by the holder.

Performance Share Units. The holder of performance share units generally will recognize ordinary income in

an amount equal to the fair market value of the Olin common stock upon issuance of the shares (or upon receipt of the

cash payment, in an amount equal to the cash payment, to the extent the performance share units are settled in cash).

Subject to the limit imposed by Code Section 162(m), Olin is entitled to a business expense deduction that corresponds to

the amount of ordinary income recognized by the holder.

Stock Appreciation Rights. Generally, the holder of a stock appreciation right recognizes no income at grant.

Upon exercise, the holder will recognize as ordinary income the excess of the value of the stock appreciation right on the

date of exercise over the value as of the date of grant. Olin is entitled to a business expense deduction that corresponds

to the amount of ordinary income recognized by the holder, subject to the limit imposed by Code Section 162(m).

Dividends and Dividend Equivalents. In general, recipients of dividend equivalents are taxable upon receipt.

Subject to the limit imposed by Code Section 162(m), Olin is entitled to a business expense deduction that corresponds to

the amount of ordinary income recognized by the recipient.

SEC Registration

If our shareholders approve the 2026 LTIP, we will file a registration statement on Form S-8 with the SEC, as soon

as reasonably practicable after the approval, to register the shares available for issuance under the 2026 LTIP.

2026 LTIP Benefits

The granting of awards under the 2026 LTIP is discretionary, and we cannot presently determine the number or

type of awards to be granted in the future to any particular person or group for 2026 or any other year, and no information

is provided concerning the benefits to be delivered under the 2026 LTIP to any individual or group of individuals. Awards

will be granted at the discretion of the Compensation Committee and, at this time, the Compensation Committee has not

determined future awards or who might receive them. Therefore, it is not possible to determine the amount or form of any

award that will be granted to any individual in the future.

Vote Required for Approval

The affirmative vote of a majority of the votes cast at the annual meeting is required to approve the 2026 LTIP. In

the event the 2026 LTIP is not approved at the annual meeting, the Prior Plans would continue in effect in accordance with

their existing terms.

Our Board recommends a vote FOR approval of the Olin Corporation 2026 Long Term Incentive Plan.

ITEM 3—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 2026 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 2025 annual meeting of shareholders, over 94

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

63

Table of Contents

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 2026 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.

ITEM 4—PROPOSAL TO RATIFY THE APPOINTMENT OF

________

(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.

64

Table of Contents

• 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 2025, 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 2026 ?

Olin’s Audit Committee is solely responsible for hiring and compensating Olin’s independent registered public

accounting firm. After considering KPMG’s 2025 performance and the fees proposed for their preliminary audit plan for

2026 , our Audit Committee has selected KPMG as our independent registered public accounting firm for 2026 .

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.

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 2026 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

independent registered public accounting firm for 2026 , our Audit Committee will take the vote into consideration in

making next year’s selection. Even if the selection is ratified, the Audit Committee in its discretion may appoint a different

independent registered public accounting firm at any time if it is determined that such a change would be in the best

interests of Olin and its shareholders.

Our Board recommends a vote FOR ratification of the appointment of KPMG as our independent

registered public accounting firm for 2026 .

Section 1. Purpose.

The general purposes of the Olin Corporation 2026 Long Term Incentive Plan (the “Plan”) are to attract and retain persons

eligible to participate in the Plan, motivate Participants with appropriate incentives to achieve long-range goals, provide

incentive compensation opportunities that are competitive with those of other similar companies, and further align

Participants’ interests with those of other shareholders of Olin Corporation through compensation that is based on Olin’s

Shares; and thereby promote the long-term financial interest of Olin and its Affiliates, including growth in the value of

Olin’s equity and enhancement of long-term shareholder return.

Olin or an Affiliate of at least 50% of the issued and outstanding stock of another corporation. The terms and

conditions of the substitute Awards so granted may vary from the terms and conditions set forth in this Plan to

any Option shall be paid at the time of such exercise (except that, in the case of an exercise arrangement

approved by the Committee and described below, payment may be made as soon as practicable after the

exercise). The exercise price shall be payable in cash or, unless the Committee prohibits it, by tendering,

by either actual delivery of Shares or by attestation, Shares acceptable to the Committee, which Shares

were either acquired at least six months before the exercise date or purchased on the open market, and

valued at Fair Market Value as of the day of exercise, or in any combination thereof, as determined by the

Committee. The Committee may permit a Participant to elect to pay the exercise price upon the exercise

of an Option by irrevocably authorizing a third party to sell Shares (or a sufficient portion of the Shares)

acquired upon exercise of an Option and remit to Olin a sufficient portion of the sale proceeds to pay the

entire exercise price and any tax withholding resulting from such exercise.

(iv) Incentive Stock Options . The terms of any Incentive Stock Option granted under the Plan shall comply in

all respects with the provisions of Section 422 of the Code, or any successor provision thereto, and any

regulations promulgated thereunder. Without limiting the preceding sentence, the aggregate Fair Market

Value (determined at the time an Option is granted) of Shares with respect to which Incentive Stock

Options are exercisable for the first time by a Participant during any Calendar Year (under the Plan and

any other plan of the Participant’s employer corporation and its parent and subsidiary corporations

providing for Options) shall not exceed such dollar limitation as shall be applicable to Incentive Stock

Options under Section 422 of the Code or a successor provision. Incentive Stock Options shall not be

granted to Non-Employee Directors.

(b) Stock Appreciation Rights . The Committee is authorized to grant Stock Appreciation Rights to Participants which

may, but need not, relate to a specific Option granted under the Plan. Subject to the terms of the Plan and any

applicable Award Agreement, each Stock Appreciation Right granted under the Plan shall confer on the holder

thereof a right to receive, upon exercise thereof, up to the excess of (i) the Fair Market Value of one Share on the

date of exercise over (ii) the exercise price of the right as specified by the Committee, which shall not be less

than the Fair Market Value of one Share on the date of grant of the Stock Appreciation Right. Subject to the

terms of the Plan and any applicable Award Agreement, the exercise price, term, methods of exercise, methods

of payment or settlement, including whether such SAR shall be paid in cash or Shares, and any other terms and

conditions of any Stock Appreciation Right shall be as determined by the Committee, provided that in no event

shall the term of a Stock Appreciation Right exceed a period of ten years from the date of its grant.

and may include, without limitation, Awards designed to comply with or take advantage of the applicable

local laws of jurisdictions other than the United States.

at such time or times, as the Committee may deem appropriate.

any combination thereof, and may be made in a single payment or transfer, in each case in accordance with rules and

procedures established by the Committee and in accordance with Code Section 409A to the extent applicable.

Section 8. Dividends and Dividend Equivalents.

An Award (other than Options or Stock Appreciation Rights) may provide the Participant with the right to receive dividends

or dividend equivalent payments with respect to Shares subject to the Award which may be settled in cash or Shares as

determined by the Committee; provided, however, that such dividends or dividend equivalents shall be subject to the

same vesting restrictions, including any service and performance conditions as the underlying Award. Any such

settlements, and any such crediting of dividends or dividend equivalents or reinvestment in Shares, may be subject to

such additional conditions, restrictions and contingencies as the Committee shall establish. Notwithstanding the foregoing,

a Participant who is entitled to dividends or dividend equivalents shall not be entitled to receive a special or extraordinary

dividend or distribution unless the Committee shall have expressly authorized such receipt.

In no event shall dividends or dividend equivalents (whether paid in cash or Shares) be paid with respect to any Options

or any Stock Appreciation Rights.

Agreement or policies adopted by the Compensation Committee, in the event the employment of a Participant to

whom an Award has been granted under the Plan shall be terminated by Olin or an Affiliate with Cause or the

applicable Participant violates any restrictive covenants entered into by the Participant and the Company or an

Affiliate, any outstanding Award, including both vested and unvested portions and any dividends and dividend

equivalents attributable thereto, shall be immediately forfeited and deemed null and void as of the date of such

termination of employment.

(b) Other Termination of Employment . Unless otherwise specified in the applicable Award Agreement or policies

adopted by the Compensation Committee, in the event the employment of a Participant to whom an Award has

been granted under the Plan shall be terminated by Olin or an Affiliate or by a Participant for any reason other

than a termination by Olin or an Affiliate with Cause:

(i) The unvested portion of the terminated Participant’s Award(s), including any dividends and dividend

equivalents attributable thereto, shall be immediately forfeited and deemed null and void as of the date of

such termination of employment; and

(ii) Any vested Option held by the Participant may be exercised at any time within three months after such

termination (which three-month period may be extended by the Committee), but in no event shall such

three-month period or any such extension permit the exercise of an Option after the expiration date of the

Option.

A-8

Table of Contents

Awards granted under the Plan shall not be affected by any change of duties or position so long as the

Participant continues to be an Employee.

(c) Other Forfeitures . For the avoidance of doubt, the Committee may specify in an Award Agreement that the

Participant’s rights, payments and benefits with respect to an Award shall be subject to reduction, cancellation,

acceleration, forfeiture or recoupment upon the occurrence of certain specified events, in addition to any

otherwise applicable vesting or performance conditions of an Award.

Section 11. Change in Control.

(a) General Rule . The provisions of this Section 11 shall apply in the case of a Change in Control, unless otherwise

provided in the Award Agreement, the operative transaction agreements related to the Change in Control, or any

separate agreement with a Participant governing an Award.

(b) Discretion to Cash Out Awards . In the event of a Change in Control, the Committee may in its discretion, cancel

any outstanding vested Awards and pay to the holders thereof, in cash or stock, or any combination thereof, the

value of such vested Awards based upon the price per Share received or to be received by other shareholders of

Olin upon such Change in Control.

(c) Assumption of Awards . In the event of a Change in Control, the surviving, continuing, successor, or purchasing

corporation or other business entity or parent thereof, as the case may be (the “Acquiror”), may, without the

consent of any Participant, assume or continue Olin’s rights and obligations under each or any Award or portion

thereof outstanding immediately prior to the Change in Control or substitute for each or any such outstanding

Award or portion thereof a substantially equivalent award with respect to the Acquiror’s stock, as applicable. For

purposes of this Section, if so determined by the Committee in its discretion, an Award denominated in Shares

shall be deemed assumed if, following the Change in Control, the Award confers the right to receive, subject to

the terms and conditions of the Plan and the applicable Award Agreement, for each Share subject to the Award

immediately prior to the Change in Control, the consideration (whether stock, cash, other securities or property or

a combination thereof) to which a holder of a Share on the effective date of the Change in Control was entitled

(and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a

majority of the outstanding Shares); provided, however, that if such consideration is not solely common stock of

the Acquiror, the Committee may, with the consent of the Acquiror, provide for the consideration to be received

upon the exercise or settlement of the Award, for each Share subject to the Award, to consist solely of common

stock of the Acquiror equal in Fair Market Value to the per Share consideration received by holders of Shares

pursuant to the Change in Control.

(d) Vesting Provisions . Unless otherwise specified in the applicable Award Agreement or policies adopted by the

Compensation Committee, (i) any Award or portion thereof which is not assumed, continued or substituted as

provided herein by the Acquiror in connection with the Change in Control, irrespective of the vesting schedule,

shall become fully vested (with any performance conditions considered achieved at target levels) and

immediately exercisable and, if applicable, the restricted period shall end as of the time of consummation of the

Change in Control and (ii) any Award or portion thereof which is assumed, continued or substituted as provided

herein by the Acquiror in connection with the Change in Control, irrespective of the vesting schedule, shall

become fully vested (with any performance conditions considered achieved at target levels) and immediately

exercisable and, if applicable, the restricted period shall end as of the time of consummation of the Change in

Control upon a Participant’s Qualifying Termination.

(e) Golden Parachute Payments . In the event any payment(s) or the value of any benefit(s) received or to be

received by a Participant in connection with or contingent upon a Change in Control (whether received or to be

received pursuant to the terms of the Plan or any Award Agreement or of any other plan, arrangement or

agreement of the Company, its successors, any person whose actions result in a Change in Control, or any

person affiliated with any of them (or which, as a result of the completion of the transaction(s) causing a Change

in Control, will become affiliated with any of them) (collectively, the “Payments”)), are determined, under the

provisions of this subsection to be subject to an excise tax imposed by Code Section 4999 (any such excise tax,

together with any interest and penalties, are hereinafter collectively referred to as the “Excise Tax”), as

determined in this subsection, then the Company shall reduce the aggregate amount of the Payments payable to

the Participant such that no Excise Tax shall be payable by the Participant and the Payments shall not cease to

be deductible by the Company by reason of Code Section 280G (or any successor provision thereto).

Notwithstanding the foregoing, the Company shall not reduce the aggregate amount of the Payments payable to

A-9

the Participant pursuant to the foregoing sentence if the After-Tax Amount (as defined below) of the unreduced

Payments is greater than the After-Tax Amount that would have been paid had the Payments been reduced

pursuant to the foregoing sentence. For purposes of this Agreement “After-Tax Amount” means the portion of a

specified amount that would remain after payment of all Excise Taxes (if any), income taxes, payroll and

withholding taxes, and other applicable taxes paid or payable by Participant in respect of such specified amount.

Any reductions shall be made in a manner intended to comply with Section 409A of the Code.

Section 12. Amendment and Termination.

(a) Amendments to the Plan . The Committee may amend, suspend, discontinue or terminate the Plan at any time;

provided that, (i) no amendment that would require approval of Olin’s shareholders under any applicable law,

regulation or rule, including the rules of any stock exchange or quotation system upon which the Shares may

then be listed or quoted shall be made without obtaining such shareholder approval and (ii) no amendment,

suspension, discontinuance or termination may apply to the terms of any outstanding Award (contingent or

otherwise) granted prior to the effective date of such amendment, suspension, discontinuance or termination, in

a manner which would reasonably be considered to be adverse to the Participant, without the Participant’s

consent.

(b) Amendments to Awards . The Committee may waive any conditions or rights with respect to, or amend, alter,

suspend, discontinue, or terminate, any unexercised or unvested Award theretofore granted, prospectively or

retroactively, without the consent of any relevant Participant or holder or beneficiary of an Award; provided that,

no amendment, alteration, suspension, discontinuance or termination may apply to the terms of any outstanding

Award (contingent or otherwise) granted prior to the effective date of such amendment, suspension or

termination, in a manner which would reasonably be considered to be adverse to the Participant, without the

Participant’s consent.

(c) Adjustments of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events . The Committee may

make adjustments in the terms and conditions of Awards in recognition of unusual or nonrecurring events

(including, without limitation, the events described in Section 4(c) hereof) affecting Olin, any Affiliate, or the

financial statements of Olin or any Affiliate, or of changes in applicable laws, regulations, or accounting

principles, whenever the Committee determines that such adjustments are appropriate in order to prevent

dilution or enlargement of the benefits to be made available under the Plan.

(d) Successors . All obligations of Olin under the Plan, with respect to any Awards granted hereunder, shall be

binding on any successor to Olin, whether the existence of such successor is the result of a direct or indirect

purchase, merger, consolidation or otherwise, of all or substantially all of the business and/or assets of Olin.

Section 13. General Provisions.

(a) Awards May Be Granted Separately or Together . Awards may be granted either alone or in addition to, in tandem

with, or in substitution for any other Award or any award or benefit granted under any other plan or arrangement

of Olin or any Affiliate, or as payment for or to assure payment of an award or benefit granted under any such

other such plan or arrangement, provided that the purchase or exercise price under an Option or other Award

encompassing the right to purchase Shares shall not be reduced by the cancellation of such Award and the

substitution of another Award. Awards so granted may be granted either at the same time as or at a different time

from the grant of such other Awards or awards or benefits.

(b) Compliance with Applicable Laws . Notwithstanding any other provision of the Plan, Olin shall have no liability to

deliver any Shares under the Plan or make any other distribution of benefits under the Plan unless such delivery

or distribution would comply with all applicable laws (including, without limitation, the requirements of the

Securities Act of 1933), and the applicable requirements of any securities exchange or similar entity.

(c) No Lien or Security Interest . No Award (other than Released Securities), and no right under any such Award,

may be pledged, attached or otherwise encumbered other than in favor of Olin, and any purported pledge,

attachment, or encumbrance thereof other than in favor of Olin shall be void and unenforceable against Olin or

any Affiliate.

(d) Limits on Transfer of Awards . No Award (other than Released Securities) or right thereunder shall be assignable

or transferable by a Participant, other than: (i) by will or the laws of descent and distribution (or, in the case of an

Award of Restricted Securities, to Olin); or (ii) in the case of Awards other than Incentive Stock Options, to the

A-10

extent permitted under the terms of the Award, by a gift or domestic relations order to any Family Member, to a

trust in which the Participant and/or his or her Family Members hold more than 50% of the beneficial interest, to

a foundation in which the Participant and/or Family Members control the management of assets, and any other

entity in which the Participant and/or his or her Family Members own more than 50% of the voting interests.

(e) Beneficiary Designations . A Participant may, in the manner established by the Committee, designate a

beneficiary or beneficiaries with respect to any Award to exercise the rights of the Participant, and to receive any

property distributable, upon the death of the Participant. Each Award, and each right under any Award, shall be

exercisable, during the Participant’s lifetime, only by the Participant or a permitted transferee, or, if permissible

under applicable law by the Participant’s guardian or legal representative.

(f) No Rights to Awards . No Employee, Participant or other Person shall have any claim to be granted an Award,

and there is no obligation for uniformity of treatment of Employees, Participants or beneficiaries of Awards under

the Plan. The terms and conditions of Awards need not be the same with respect to each recipient. The

prospective recipient of any Award under the Plan shall not, with respect to such Award, be deemed to have

become a Participant, or to have any rights with respect to such Award, until and unless such recipient shall have

executed an agreement or other instrument accepting the Award required by the Committee and delivered a fully

executed copy thereof to Olin, and otherwise complied with the then applicable terms and conditions.

(g) No Right to Employment . The grant of an Award shall not be construed as giving a Participant the right to be

retained in the employ of Olin or any Affiliate. Nothing in the Plan or any Award Agreement shall limit the right of

Olin or an Affiliate at any time to dismiss a Participant from employment, free from any liability or any claim under

the Plan or the Award Agreement.

(h) Rights of a Shareholder . No Award shall confer on any Participant any of the rights of a shareholder of Olin

unless and until Shares are in fact issued to such Participant, without restriction, in connection with such Award.

(i) Withholding . All distributions under the Plan are subject to withholding of all applicable taxes, and, except as

otherwise provided by the Committee, the delivery of any Shares or other benefits under the Plan to a Participant

are conditioned on satisfaction of the applicable withholding requirements. With respect to withholding required

upon the exercise of Options or SARs, upon the lapse of restrictions on Restricted Stock and Restricted Stock

Units, or upon the achievement of performance goals related to Performance Shares, or any other taxable event

arising as a result of an Award granted hereunder, Participants may elect to satisfy the withholding requirement,

at the Committee’s discretion, in whole or in part, by having Olin withhold Shares having a Fair Market Value on

the date the tax is to be determined (A) subject to the approval of the Committee, equal to the minimum statutory

total tax that could be imposed on the transaction, or (B) solely to the extent authorized by the Committee in

advance, at a higher rate up to the maximum statutory total tax that could be imposed on the transaction. All

such elections shall be irrevocable, made in writing, and signed by the Participant, and shall be subject to any

restrictions or limitations that the Committee, in its sole discretion, deems appropriate. No opinion is expressed

nor warranties made as to the tax effects under federal, foreign, state or local laws or regulations of any Award

granted under the Plan. Regardless of whether Awards are intended to qualify for favorable tax treatment, Olin

does not warrant or represent that such treatment will be available.

(j) Whistleblower Provisions . Nothing contained herein prohibits the Participant from: (i) reporting possible violations

of federal law or regulations, including any possible securities laws violations, to any governmental agency or

entity, (ii) making any other disclosures that are protected under the whistleblower provisions of federal law or

regulations, or (iii) otherwise fully participating in any federal whistleblower programs, including but not limited to

any such programs managed by the U.S. Securities and Exchange.

(k) Governing Law . The validity, construction and effect of the Plan and any rules and regulations relating to the Plan

shall be determined in accordance with the laws of the State of Missouri, excluding any conflicts or choice of law

rule or principle that might otherwise refer construction or interpretation of this Plan or any Award Agreement to

the substantive law of another jurisdiction. Any legal action against the Plan, Olin, an Affiliate, or the Committee

may only be brought in the Circuit Court in St. Louis County and/or the United States District Court in St. Louis,

Missouri.

(l) Severability . If any provision of the Plan or any Award is determined to be invalid, illegal or unenforceable, or as

to any Person or Award, or would disqualify the Plan or any Award, such provision shall be construed or deemed

amended to conform to applicable laws, or, if it cannot be so construed or deemed amended without, in the

determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be

A-11

Table of Contents

stricken as to such Person or Award, and the remainder of the Plan and any such Award shall remain in full force

and effect.

(m) No Trust or Fund Created . Neither the Plan nor any Award shall create or be construed to create a trust or

separate fund of any kind or a fiduciary relationship between Olin or any Affiliate and a Participant or any other

Person. To the extent that any Person acquires a right to receive payments from Olin or any Affiliate pursuant to

an Award, such right shall be no greater than the right of any unsecured general creditor of Olin or any Affiliate.

(n) Share Certificates . All certificates for Shares or other securities delivered under the Plan pursuant to any Award

or the exercise thereof shall be subject to such stop transfer orders and other restrictions as the Committee may

deem advisable under the Plan or the rules, regulations and other requirements of the Securities and Exchange

Commission, any stock exchange upon which such Shares or other securities are then listed, and any applicable

Federal or state securities laws, and the Committee may cause a legend or legends to be put on any such

certificates to make appropriate reference to such restrictions. To the extent that the Plan provides for issuance

of stock certificates to reflect the issuance of Shares the issuance may be effected on a non-certificated basis, to

the extent not prohibited by applicable law or the applicable rules of any stock exchange.

(o) Award Agreement . The terms of any plan or guideline adopted by the Committee and applicable to an Award

shall be deemed incorporated in and a part of the related Award Agreement. The Committee may provide for the

use of electronic, internet or other non-paper Award Agreements, and the use of electronic, internet or other non-

paper means for the Participant’s acceptance of, or actions under, an Award Agreement. In the event of any

inconsistency or conflict between the terms of the Plan and an Award Agreement, the terms of the Plan shall

govern.

(p) Olin Policies . Notwithstanding any other provisions of this Plan, (i) all Awards will be subject to any Company

policy that Olin or an Affiliate may adopt and/or amend from time to time regarding the hedging or pledging (or

any similar transaction) of Company securities and (ii) all Awards shall be subject to such deductions and

clawback as may be required to be made pursuant to any law, government regulation or stock exchange listing

requirement, or any policy adopted by Olin or an Affiliate, regardless of when such policy is adopted.

(q) 409A Compliance . It is intended that the Plan (and any Award) will comply with or be exempt from Code Section

409A, and the Plan (and any Award) shall be interpreted and construed on a basis consistent with such intent.

The Plan (and any Award) may be amended in any respect deemed necessary (including retroactively) by the

Committee in order to preserve compliance with or exemption from Code Section 409A. The preceding shall not

be construed as a guarantee of any particular tax effect for Plan benefits or Awards. A Participant (or beneficiary)

is solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on the

Participant (or beneficiary) in connection with any Award to such Participant (or beneficiary) under the Plan

(including any taxes and penalties under Code Section 409A), and neither Olin nor any Affiliate shall have any

obligation to indemnify or otherwise hold a Participant (or beneficiary) harmless from any or all of such taxes or

penalties.

Section 14. Effective Date and Term.

The Plan shall be effective as of the Effective Date and, if not terminated earlier pursuant to Section 12, shall remain in

effect until the tenth anniversary of the Effective Date. In the event of a Plan termination, the Plan shall remain in effect as

long as any Awards under it are outstanding; provided; however, that, to the extent required by the Code, no Incentive

Stock Option may be granted under the Plan on a date that is more than ten years from the Effective Date.
