Notes to Condensed Financial Statements

(Unaudited)

NOTE 1. DESCRIPTION OF BUSINESS

Olin Corporation (Olin) is a Virginia corporation, incorporated in 1892, having its principal executive offices in Clayton, MO. We are a leading vertically integrated global manufacturer and distributor of chemical products and a leading U.S. manufacturer of ammunition. Our operations are concentrated in three business segments: Chlor Alkali Products and Vinyls, Epoxy and Winchester. All of our business segments are capital-intensive manufacturing businesses. The Chlor Alkali Products and Vinyls segment manufactures and sells chlorine and caustic soda, ethylene dichloride and vinyl chloride monomer, methyl chloride, methylene chloride, chloroform, carbon tetrachloride, perchloroethylene, hydrochloric acid, hydrogen, bleach products and potassium hydroxide. The Epoxy segment produces and sells a full range of epoxy materials and precursors, including aromatics (acetone and phenol), allyl chloride, epichlorohydrin, liquid epoxy resins, solid epoxy resins and systems and growth products such as converted epoxy resins and additives. The Winchester segment produces and sells sporting ammunition, reloading components, small caliber military ammunition and components, industrial cartridges and clay targets.

On January 10, 2023, Blue Water Alliance (BWA), our joint venture with Mitsui & Co., Ltd. (Mitsui), began operations. BWA is an independent global trader of Electrochemical Unit (ECU)-based derivatives, focused on globally traded caustic soda and ethylene dichloride. Olin holds 51% interest and exercises control in BWA, and the joint venture is consolidated in our consolidated financial statements in our Chlor Alkali Products and Vinyls segment, with Mitsui’s 49% interest in BWA classified as noncontrolling interest. All intercompany accounts and transactions are eliminated in consolidation.

We have prepared the condensed financial statements included herein, without audit, pursuant to the rules and regulations of the United States (U.S.) Securities and Exchange Commission (SEC). The preparation of the financial statements requires estimates and assumptions that affect amounts reported and disclosed in the financial statements and related notes. In our opinion, these financial statements reflect all adjustments (consisting only of normal accruals), which are necessary to present fairly the results for interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations; however, we believe that the disclosures are appropriate. We recommend that you read these condensed financial statements in conjunction with the financial statements, accounting policies and the notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2023.

NOTE 2. RECENT ACCOUNTING PRONOUNCEMENTS

In March 2024, the SEC issued SEC Release No. 33-11042, Enhancement and Standardization of Climate-Related Disclosures for Investors, to enhance and standardize the climate-related disclosures provided by public companies. The final rule will require the disclosure of greenhouse gas emissions, including Scope 1 and Scope 2 emissions, which will be subject to third-party assurance, as well as climate-related targets and goals, and how the Board of Directors and management oversee climate-related risks. Within the notes to financial statements, the final rule requires disclosure of expenditures recognized, subject to certain thresholds, attributable to severe weather events. The final rule follows a compliance phase-in timeline, with the first requirements required to be adopted with our fiscal year ending December 31, 2025, followed in later years by greenhouse gas-related requirements. On April 4, 2024, the SEC voluntarily stayed the implementation of these disclosure requirements; however, we are currently evaluating the impact of the final rule on our disclosures.

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The amendments are effective for annual periods beginning after December 15, 2024, with the option to early adopt at any time before the effective date. ASU 2023-09 allows for adoption on a prospective or retrospective basis. We will adopt this standard beginning with our fiscal year ending December 31, 2025. We are currently evaluating the impact of the standard on our consolidated financial statements and disclosures.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures. ASU 2023-07 will improve reportable segment disclosure requirements, primarily through enhanced segment expense disclosures on an interim and annual basis. The update is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with the option to early adopt at any time before the effective date. ASU 2023-07 requires adoption on a retrospective basis. We will adopt this standard beginning with our fiscal year ending December 31, 2024, and for interim periods beginning with our first quarter fiscal year 2025. We are currently evaluating the impact of the standard on our consolidated financial statements and disclosures.

NOTE 3. ACQUISITIONS

On October 1, 2023, Olin acquired the assets of White Flyer Targets, LLC (White Flyer) from Reagent Diversified Holdings, Inc. for $63.5 million. The acquisition was financed with cash on hand. White Flyer designs, manufactures and sells recreational trap, skeet, international and sporting clay targets and has been included in Olin’s Winchester segment. We recorded the aggregate excess purchase price over identifiable net tangible and intangible assets acquired and liabilities assumed, which included a final allocation of $2.4 million of goodwill allocated to our Winchester segment and $4.5 million of intangible assets subject to amortization. The final total assets acquired, excluding goodwill and intangibles, and liabilities assumed amounted to $66.6 million and $10.0 million, respectively. The acquisition is not material, and therefore, supplemental pro forma financial information is not provided.

NOTE 4. RESTRUCTURING CHARGES

As a result of weak global resin demand and higher cost structures within the European region, we began a review of our global Epoxy asset footprint to optimize the most productive and cost-effective assets to support our strategic operating model. As part of this review, we announced operational cessations in the fourth quarter of 2022 and the first half of 2023 (collectively, Epoxy Optimization Plan).

On June 20, 2023, we announced we had made the decision to cease all remaining operations at our Gumi, South Korea facility, reduce epoxy resin capacity at our Freeport, TX facility, and reduce our sales and support staffing across Asia. These actions were substantially completed by December 31, 2023. On March 21, 2023, we announced we had made the decision to cease operations at our cumene facility in Terneuzen, Netherlands and solid epoxy resin production at our facilities in Gumi, South Korea and Guaruja, Brazil. The closures were completed in the first quarter 2023. During the fourth quarter of 2022, we committed to and completed a plan to close down one of our bisphenol production lines at our Stade, Germany site. We expect to incur additional restructuring charges through 2025 of approximately $10 million related to these actions.

During 2021, we announced that we had made the decision to permanently close our diaphragm-grade chlor alkali capacity, representing 400,000 tons, at our McIntosh, AL facility (McIntosh Plan). The closure was completed during the third quarter of 2022. We expect to incur additional restructuring charges through 2027 of approximately $20 million related to these actions.

On January 18, 2021, we announced we had made the decision to permanently close our trichloroethylene and anhydrous hydrogen chloride liquefaction facilities in Freeport, TX (collectively, Freeport 2021 Plan), which were completed in the fourth quarter of 2021. We expect to incur additional restructuring charges through 2025 of approximately $5 million related to these actions.

On December 11, 2019, we announced that we had made the decision to permanently close a chlor alkali plant with a capacity of 230,000 tons and our vinylidene chloride (VDC) production facility, both in Freeport, TX (collectively, Freeport 2019 Plan). The VDC facility and related chlor alkali plant were closed during the fourth quarter of 2020 and second quarter of 2021, respectively. We expect to incur additional restructuring charges through 2026 of approximately $15 million related to these actions.

Pretax restructuring charges related to these actions include facility exit costs, lease and other contract termination costs, employee severance and related benefits costs and the write-off of equipment and facilities. Pretax restructuring charges, by plan, for the three and nine months ended September 30, 2024 and 2023, were as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2024		2023		2024		2023

NOTE 5. EARNINGS PER SHARE

Basic and diluted net (loss) income attributable to Olin Corporation per share are computed by dividing net (loss) income attributable to Olin Corporation by the weighted-average number of common shares outstanding. Diluted net (loss) income attributable to Olin Corporation per share reflects the dilutive effect of stock-based compensation.

NOTE 6. ACCOUNTS RECEIVABLES

We maintain a $425.0 million Receivables Financing Agreement (Receivables Financing Agreement) that is scheduled to mature on October 14, 2025. Under the Receivables Financing Agreement, our eligible trade receivables are used for collateralized borrowings and continue to be serviced by us. In addition, the Receivables Financing Agreement incorporates the net leverage ratio covenant that is contained in the $1,550.0 million Senior Credit Facility. As of September 30, 2024, December 31, 2023 and September 30, 2023, we had $339.8 million, $328.5 million and $350.0 million, respectively, drawn under the agreement. As of September 30, 2024, $473.9 million of our trade receivables were pledged as collateral and we had $0.3 million additional borrowing capacity under the Receivables Financing Agreement, which was limited by our borrowing base.

Olin also has trade accounts receivable factoring arrangements (AR Facilities) and pursuant to the terms of the AR Facilities, certain of our domestic subsidiaries may sell their accounts receivable up to a maximum of $134.5 million and certain of our foreign subsidiaries may sell their accounts receivable up to a maximum of €16.5 million. We will continue to service the outstanding accounts sold. These receivables qualify for sales treatment under ASC 860 “Transfers and Servicing” and, accordingly, the proceeds are included in net cash provided by operating activities in the condensed statements of cash flows. 

The following table summarizes the AR Facilities activity:

	Nine Months Ended September 30,
	2024		2023
AR Facilities	($ in millions)
Balance at beginning of year	$	63.3	$	111.8
Gross receivables sold	528.5		749.5
Payments received from customers on sold accounts	(539.5)		(788.6)
Balance at end of period	$	52.3	$	72.7

The factoring discount paid under the AR Facilities is recorded as interest expense on the condensed statements of operations. The factoring discount was $0.8 million and $1.3 million for the three months ended September 30, 2024 and 2023, respectively, and $2.9 million and $3.8 million for the nine months ended September 30, 2024 and 2023, respectively. The agreements are without recourse and therefore no recourse liability had been recorded as of September 30, 2024.

Our condensed balance sheets included an allowance for doubtful accounts receivables of $12.2 million, $13.1 million and $12.8 million and other receivables of $94.5 million, $85.3 million and $78.0 million at September 30, 2024, December 31, 2023 and September 30, 2023, respectively, which were included in receivables, net.

NOTE 7. INVENTORIES

Inventories consisted of the following:

	September 30, 2024		December 31, 2023		September 30, 2023

Inventories under the LIFO method are based on annual estimates of quantities and costs as of year-end; therefore, the condensed financial statements at September 30, 2024, reflect certain estimates relating to inventory quantities and costs at December 31, 2024. The replacement cost of our inventories would have been approximately $167.9 million, $133.7 million and $154.8 million higher than reported at September 30, 2024, December 31, 2023 and September 30, 2023, respectively.

Senior Credit Facility

We maintain a $1,550.0 million senior credit facility (Senior Credit Facility) which includes a senior term loan facility with aggregate commitments of $350.0 million (Term Loan Facility) and a senior revolving credit facility with aggregate commitments of $1,200.0 million (Senior Revolving Credit Facility). The Term Loan Facility was fully drawn on the closing date with the proceeds of the Term Loan Facility used to refinance the loans and commitments outstanding under the existing facility. The Term Loan Facility requires principal amortization payments which began on March 31, 2023, at a rate of 0.625% per quarter through the end of 2024, increasing to 1.250% per quarter thereafter until maturity. The maturity date for the Senior Credit Facility is October 11, 2027.

The Senior Revolving Credit Facility includes a $100.0 million letter of credit subfacility. At September 30, 2024, we had $849.6 million available under our $1,200.0 million Senior Revolving Credit Facility because we had $350.0 million borrowed under the facility and issued $0.4 million of letters of credit. During the second quarter of 2024, we utilized our Senior Revolving Credit Facility to repay $50.0 million of Go Zone and $20.0 million of Recovery Zone tax-exempt variable-rate bonds.

We were in compliance with all covenants and restrictions under all our outstanding credit agreements as of September 30, 2024, and no event of default had occurred that would permit the lenders under our outstanding credit agreements to accelerate the debt if not cured. In the future, our ability to generate sufficient operating cash flows, among other factors, will determine the amounts available to be borrowed under these facilities. As a result of our restrictive covenant related to the net leverage ratio, the maximum additional borrowings available to us could be limited in the future. The limitation, if an amendment or waiver from our lenders is not obtained, could restrict our ability to borrow the maximum amounts available under the Senior Revolving Credit Facility and the Receivables Financing Agreement. As of September 30, 2024, there were no covenants or other restrictions that limited our ability to borrow.

NOTE 11. PENSION PLANS AND RETIREMENT BENEFITS

We sponsor domestic and foreign defined benefit pension plans for eligible employees and retirees. Most of our domestic employees participate in defined contribution plans. However, a portion of our bargaining hourly employees continue to participate in our domestic qualified defined benefit pension plans under a flat-benefit formula. Our funding policy for the qualified defined benefit pension plans is consistent with the requirements of federal laws and regulations. Our foreign subsidiaries maintain pension and other benefit plans, which are consistent with local statutory practices.

Our domestic qualified defined benefit pension plan provides that if, within three years following a change of control of Olin, any corporate action is taken or filing made in contemplation of, among other things, a plan termination or merger or other transfer of assets or liabilities of the plan, and such termination, merger, or transfer thereafter takes place, plan benefits would

14

automatically be increased for affected participants (and retired participants) to absorb any plan surplus (subject to applicable collective bargaining requirements).

We also provide certain postretirement healthcare (medical) and life insurance benefits for eligible active and retired domestic employees. The healthcare plans are contributory with participants’ contributions adjusted annually based on medical rates of inflation and plan experience.

We made cash contributions to our international qualified defined benefit pension plans of $0.9 million and $1.6 million for the nine months ended September 30, 2024 and 2023, respectively.

NOTE 12. INCOME TAXES

The effective tax rate for the three months ended September 30, 2024 included a net $2.9 million tax expense, primarily associated with a change in tax contingencies and remeasurement of deferred taxes due to an increase in our state effective tax rates, partially offset by a benefit from prior year tax positions. Excluding these items, the effective tax rate for the three months ended September 30, 2024 of 11.5% was lower than the 21.0% U.S. federal statutory rate primarily due to state income tax, foreign income inclusions and an increase in the estimated annual effective tax rate, partially offset by favorable permanent salt depletion deductions. The effective tax rate for the three months ended September 30, 2023 included a net $7.2 million tax benefit, primarily associated with stock-based compensation and prior year tax positions, partially offset by an expense from a change in tax contingencies. Excluding these items, the effective tax rate for the three months ended September 30, 2023 of 23.2% was higher than the 21.0% U.S. federal statutory rate primarily due to state income tax and an increase in the valuation allowance related to losses in foreign jurisdictions, partially offset favorable permanent salt depletion deductions and foreign income taxes.

The effective tax rate for the nine months ended September 30, 2024 included a net $0.4 million tax benefit, primarily associated with stock-based compensation, U.S. Federal tax credits purchased at a discount, and a benefit from prior year tax positions, partially offset by a change in tax contingencies and remeasurement of deferred taxes due to an increase in our state effective tax rates. Excluding these items, the effective tax rate for the nine months ended September 30, 2024 of 28.2% was higher than the 21.0% U.S. federal statutory rate primarily due to state income tax and foreign income inclusions, partially offset by favorable permanent salt depletion deductions. The effective tax rate for the nine months ended September 30, 2023 included a net $24.4 million tax benefit, primarily associated with stock-based compensation and prior year tax positions, partially offset by an expense from a change in tax contingencies. Excluding these items, the effective tax rate for

15

the nine months ended September 30, 2023 of 24.1% was higher than the 21.0% U.S. federal statutory rate primarily due to state income tax and an increase in the valuation allowance related to losses in foreign jurisdictions, partially offset by favorable permanent salt depletion deductions.

In August 2022, the Inflation Reduction Act (the "IRA") was enacted and provides various beneficial credits for energy efficient related manufacturing, transportation and fuels, hydrogen/carbon recapture and renewable energy, which we are evaluating in regard to planned projects. We will continue to monitor the expected impacts of any new guidance on our filing positions and will record the impacts as discrete income tax expense adjustments in the period the guidance is finalized or becomes effective.

As of September 30, 2024, we had $55.9 million of gross unrecognized tax benefits, which would have a net $55.9 million impact on the effective tax rate, if recognized. The amounts of unrecognized tax benefits were as follows:

	Nine Months Ended September 30,
	2024		2023
Unrecognized Tax Benefits	($ in millions)
Balance at beginning of year	$	50.3	$	51.6
Increases for prior year tax positions	5.6		1.3
Decreases for prior year tax positions	(0.4)		(0.3)
Increases for current year tax positions	1.2		10.1
Decreases due to tax settlements	(1.0)		—
Foreign currency translation adjustments	0.2		(0.6)
Balance at end of period	$	55.9	$	62.1

As of September 30, 2024, we believe it is reasonably possible that our total amount of unrecognized tax benefits will decrease by approximately $38.0 million over the next twelve months. The anticipated reduction primarily relates to expected settlements with tax authorities and the expiration of federal, state and foreign statutes of limitation.

We operate globally and file income tax returns in numerous jurisdictions. Our tax returns are subject to examination by various federal, state and local tax authorities. Additionally, examinations are ongoing in various states and foreign jurisdictions. We believe we have adequately provided for all tax positions; however, amounts asserted by taxing authorities could be greater than our accrued position.

For our primary tax jurisdictions, the tax years that remain subject to examination are as follows:

	Tax Years
U.S. federal income tax	2020 - 2023
U.S. state income tax	2012 - 2023
Canadian federal income tax	2017 - 2023
Brazil	2017 - 2023
Germany	2015 - 2023
China	2014 - 2023
The Netherlands	2018 - 2023

NOTE 13. DEFINED CONTRIBUTION PLAN

We sponsor a defined contribution plan for qualifying domestic employees, for which the company contributes between 5.0% and 7.5% of the employees eligible compensation into a retirement account (Company Contribution). Employees generally vest in the value of the Company Contribution according to a schedule based on service. Participants vest 50% after 2 years of service and 100% after 3 years of service. We also match a percentage of our employees contributions (Company Match), which are invested in the same investment allocation as the employee’s contributions. Employees immediately vest in the Company Match.

16

Our contributions to the defined contribution plan were as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2024		2023		2024		2023
Defined Contribution Plan Expense	($ in millions)
Company Contribution	$	8.0	$	8.4	$	27.4	$	28.6
Company Match	3.2		3.6		10.5		11.0
Total expense	$	11.2	$	12.0	$	37.9	$	39.6

NOTE 14. STOCK-BASED COMPENSATION

Stock-based compensation granted includes stock options, performance share awards, restricted stock awards and deferred directors’ compensation. Stock-based compensation expense was as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2024		2023		2024		2023
Stock Compensation Expense	($ in millions)
Stock-based compensation	$	6.3	$	6.7	$	17.3	$	19.5
Mark-to-market adjustments	0.3		(2.3)		(2.9)		(2.4)
Total expense	$	6.6	$	4.4	$	14.4	$	17.1

Stock Options

The fair value of each stock option granted, which typically vests ratably over three years, but not less than one year, was estimated on the date of grant, using the Black-Scholes option-pricing model with the following weighted-average assumptions:

Grant Date Assumptions - Stock Options	2024			2023
Dividend yield	1.50		%	1.32		%
Risk-free interest rate	4.35		%	4.07		%
Expected volatility of Olin common stock	47		%	47		%
Expected life (years)	7.0			7.0
Weighted-average grant fair value (per option)	$	24.79		$	28.74
Weighted-average exercise price	$	53.43		$	60.55
Stock options granted	606,157			562,124

Dividend yield was based on our current dividend yield as of the option grant date. Risk-free interest rate was based on zero coupon U.S. Treasury securities rates for the expected life of the options. Expected volatility was based on our historical stock price movements, as we believe that historical experience is the best available indicator of the expected volatility. Expected life of the option grant was based on historical exercise and cancellation patterns, as we believe that historical experience is the best estimate for future exercise patterns.

Performance Shares

Performance share awards are denominated in shares of our stock and are paid half in cash and half in stock. Payouts for performance share awards are based on two criteria: (1) 50% of the award is based on Olin’s total shareholder returns (TSR) over the applicable three-year performance cycle in relation to the TSR over the same period among a portfolio of public companies which are selected in concert with outside compensation consultants and (2) 50% of the award is based on Olin’s net income over the applicable three-year performance cycle in relation to the net income goal for such period as set by the Compensation Committee of Olin’s Board of Directors. The expense associated with performance shares is recorded based on our estimate of our performance relative to the respective target. If an employee leaves the company before the end of the performance cycle, the performance shares may be prorated based on the number of months of the performance cycle worked and are settled in cash instead of half in cash and half in stock when the three-year performance cycle is completed.

17

The fair value of each performance share award based on net income was estimated on the date of grant, using the current stock price. The fair value of each performance share award based on TSR was estimated on the date of grant, using a Monte Carlo simulation model with the following weighted average assumptions:

Grant Date Assumptions - Performance Shares	2024			2023
Risk-free interest rate	4.53		%	4.46		%
Expected volatility of Olin common stock	41		%	52		%
Expected average volatility of peer companies	37		%	42		%
Average correlation coefficient of peer companies	0.40			0.51
Expected life (years)	3.0			3.0
Grant date fair value (TSR-based award)	$	72.80		$	86.98
Grant date fair value (net income-based award)	$	54.07		$	60.55
Performance share awards granted	180,714			161,474

The risk-free interest rate was based on zero coupon U.S. Treasury securities rates for the expected life of the performance share awards. The expected volatility of Olin common stock and peer companies was based on historical stock price movements, as we believe that historical experience is the best available indicator of the expected volatility. The average correlation coefficient of peer companies was determined based on historical trends of Olin’s common stock price compared to the peer companies. Expected life of the performance share award grant was based on historical exercise and cancellation patterns, as we believe that historical experience is the best estimate of future exercise patterns.

NOTE 15. SHAREHOLDERS’ EQUITY

On July 28, 2022, our Board of Directors authorized a share repurchase program for the purchase of shares of common stock at an aggregate price of up to $2.0 billion (the 2022 Repurchase Authorization). This program will terminate upon the purchase of $2.0 billion of common stock.

For the nine months ended September 30, 2024 and 2023, 4.9 million and 10.8 million shares, respectively, of common stock were repurchased and retired at a total value of $256.8 million and $595.1 million, respectively. As of September 30, 2024, 24.2 million shares of common stock have been repurchased and retired at a total value of $1,258.0 million under the 2022 Repurchase Authorization program, and $742.0 million of common stock remained authorized to be repurchased under the program.

We issued 0.9 million and 0.8 million shares representing stock options exercised for the nine months ended September 30, 2024 and 2023, respectively, with a total value of $22.6 million and $22.3 million, respectively.

NOTE 16. SEGMENT INFORMATION

We define segment results as income (loss) before interest expense, interest income, other operating income (expense), non-operating pension income, other income and income taxes. We have three operating segments: Chlor Alkali Products and Vinyls, Epoxy, and Winchester. The three operating segments reflect the organization used by our management for purposes of allocating resources and assessing performance. Chlorine and caustic soda used in our Epoxy segment is transferred at cost from the Chlor Alkali Products and Vinyls segment. Sales are attributed to geographic areas based on customer location.

(1)    For the three months ended September 30, 2024 and 2023, revenue recognized over time represented $63.0 million and $28.7 million, respectively, and for the nine months ended September 30, 2024 and 2023, revenue recognized over time represented $120.6 million and $77.5 million, respectively, associated with governmental contracts within our Winchester business.

NOTE 17. ENVIRONMENTAL

We are party to various government and private environmental actions associated with past manufacturing facilities and former waste disposal sites. The condensed balance sheets included reserves for future environmental expenditures to investigate and remediate known sites amounting to $154.2 million, $153.6 million and $153.5 million at September 30, 2024,

21

December 31, 2023 and September 30, 2023, respectively, of which $122.2 million, $121.6 million and $128.5 million, respectively, were classified as other noncurrent liabilities.

Environmental provisions charged to income, which are included in costs of goods sold, were $7.2 million and $6.9 million for the three months ended September 30, 2024 and 2023, respectively, and $19.4 million and $23.1 million for the nine months ended September 30, 2024 and 2023, respectively.

Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, developments at sites resulting from investigatory studies, advances in technology, changes in environmental laws and regulations and their application, changes in regulatory authorities, the scarcity of reliable data pertaining to identified sites, the difficulty in assessing the involvement and financial capability of other Potentially Responsible Parties (PRPs), our ability to obtain contributions from other parties and the lengthy time periods over which site remediation occurs. It is possible that some of these matters (the outcomes of which are subject to various uncertainties) may be resolved unfavorably to us, which could materially adversely affect our financial position or results of operations.

NOTE 18. COMMITMENTS AND CONTINGENCIES

We, and our subsidiaries, are defendants in various legal actions (including proceedings based on alleged exposures to asbestos) incidental to our past and current business activities. As of September 30, 2024, December 31, 2023 and September 30, 2023, our condensed balance sheets included accrued liabilities for these other legal actions of $14.1 million, $14.2 million and $15.3 million, respectively. These liabilities do not include costs associated with legal representation. Based on our analysis, and considering the inherent uncertainties associated with litigation, we do not believe that it is reasonably possible that these legal actions will materially adversely affect our financial position, cash flows or results of operations.

During the ordinary course of our business, contingencies arise resulting from an existing condition, situation or set of circumstances involving an uncertainty as to the realization of a possible gain contingency. In certain instances, such as environmental projects, we are responsible for managing the cleanup and remediation of an environmental site. There exists the possibility of recovering a portion of these costs from other parties. We account for gain contingencies in accordance with the provisions of ASC 450 “Contingencies” and, therefore, do not record gain contingencies and recognize income until it is earned and realizable.

NOTE 19. DERIVATIVE FINANCIAL INSTRUMENTS

We are exposed to market risk in the normal course of our business operations due to our purchases of certain commodities, our ongoing investing and financing activities and our operations that use foreign currencies. The risk of loss can be assessed from the perspective of adverse changes in fair values, cash flows and future earnings. We have established policies and procedures governing our management of market risks and the use of financial instruments to manage exposure to such risks. ASC 815 “Derivatives and Hedging” (ASC 815) requires an entity to recognize all derivatives as either assets or liabilities in the condensed balance sheets and measure those instruments at fair value. In accordance with ASC 815, we designate derivative contracts as cash flow hedges of forecasted purchases of commodities and forecasted interest payments related to variable-rate borrowings and designate certain interest rate swaps as fair value hedges of fixed-rate borrowings. We do not enter into any derivative instruments for trading or speculative purposes.

Energy costs, including electricity and natural gas, and certain raw materials used in our production processes are subject to price volatility. Depending on market conditions, we may enter into futures contracts, forward contracts, commodity swaps and put and call option contracts in order to reduce the impact of commodity price fluctuations. The majority of our commodity derivatives expire within one year.

We actively manage currency exposures that are associated with net monetary asset positions, currency purchases and sales commitments denominated in foreign currencies and foreign currency denominated assets and liabilities created in the normal course of business. We enter into forward sales and purchase contracts to manage currency risk to offset our net exposures, by currency, related to the foreign currency denominated monetary assets and liabilities of our operations. All of the currency derivatives expire within one year and are for U.S. dollar (USD) equivalents. The counterparties to the forward contracts are large financial institutions; however, the risk of loss to us in the event of nonperformance by a counterparty could be significant to our financial position or results of operations. We had the following notional amounts of outstanding forward contracts to buy and sell foreign currency:

	September 30, 2024		December 31, 2023		September 30, 2023

Sell	148.8		140.2		155.2

Cash Flow Hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the change in fair value of the derivative is recognized as a component of other comprehensive income (loss) until the hedged item is recognized in earnings.

We had the following notional amounts of outstanding commodity contracts that were entered into to hedge forecasted purchases:

	September 30, 2024		December 31, 2023		September 30, 2023
Notional Value - Commodity	($ in millions)
Natural gas	$	64.3	$	63.2	$	67.2
Ethane	24.3		26.4		25.5
Metals	118.6		101.4		114.8
Total notional	$	207.2	$	191.0	$	207.5

As of September 30, 2024, the counterparties to these commodity contracts were Wells Fargo Bank, N.A., Citibank, N.A., JPMorgan Chase Bank, National Association, Toronto Dominion Bank and Bank of America Corporation, all of which are major financial institutions.

We use cash flow hedges for certain raw material and energy costs such as copper, zinc, lead, ethane, electricity and natural gas to provide a measure of stability in managing our exposure to price fluctuations associated with forecasted purchases of raw materials and energy used in our manufacturing process. At September 30, 2024, we had open derivative contract positions through 2028. If all open futures contracts had been settled on September 30, 2024, we would have recognized a pretax gain of $14.3 million.

If commodity prices were to remain at September 30, 2024 levels, approximately $7.3 million of deferred gains, net of tax, would be reclassified into earnings during the next twelve months. The actual effect on earnings will be dependent on actual commodity prices when the forecasted transactions occur.

Fair Value Hedges

We use interest rate swaps as a means of managing interest expense and floating interest rate exposure to optimal levels. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings. We include the gain or loss on the hedged items (fixed-rate borrowings) in the same line item, interest expense, as the offsetting loss or gain on the related interest rate swaps. There were no outstanding interest rate swaps at September 30, 2024, December 31, 2023 and September 30, 2023.

Financial Statement Impacts

We present our derivative assets and liabilities in our condensed balance sheets on a net basis whenever we have a legally enforceable master netting agreement with the counterparty to our derivative contracts. We use these agreements to manage and substantially reduce our potential counterparty credit risk.

The following table summarizes the location and fair value of the derivative instruments on our condensed balance sheets:

Credit Risk and Collateral

By using derivative instruments, we are exposed to credit and market risk. If a counterparty fails to fulfill its performance obligations under a derivative contract, our credit risk will equal the fair value gain in a derivative. Generally, when the fair value of a derivative contract is positive, this indicates that the counterparty owes us, thus creating a repayment risk for us. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, assume no repayment risk. We minimize the credit (or repayment) risk in derivative instruments by entering into transactions with high-quality counterparties. We monitor our positions and the credit ratings of our counterparties, and we do not anticipate non-performance by the counterparties.

Based on the agreements with our various counterparties, cash collateral is required to be provided when the net fair value of the derivatives, with the counterparty, exceeds a specific threshold. If the threshold is exceeded, cash is either provided by the counterparty to us if the value of the derivatives is our asset, or cash is provided by us to the counterparty if the value of the derivatives is our liability. As of September 30, 2024, December 31, 2023 and September 30, 2023, this threshold was not exceeded. In all instances where we are party to a master netting agreement, we offset the receivable or payable recognized upon payment of cash collateral against the fair value amounts recognized for derivative instruments that have also been offset under such master netting agreements.

NOTE 20. FAIR VALUE MEASUREMENTS

Fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties or the amount that would be paid to transfer a liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is based on observable market prices or parameters or derived

24

from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity.

Assets and liabilities recorded at fair value in the condensed balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, defined by ASC 820 “Fair Value Measurement” (ASC 820), and directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows:

Level 1 — Inputs were unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2 — Inputs (other than quoted prices included in Level 1) were either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.

Level 3 — Inputs reflected management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration was given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

We are required to separately disclose assets and liabilities measured at fair value on a recurring basis, from those measured at fair value on a nonrecurring basis. Nonfinancial assets measured at fair value on a nonrecurring basis are intangible assets and goodwill, which are reviewed for impairment annually in the fourth quarter and/or when circumstances or other events indicate that impairment may have occurred.

Commodity Contracts

We use commodity derivative contracts for certain raw materials and energy costs such as copper, zinc, lead, ethane, electricity and natural gas to provide a measure of stability in managing our exposure to price fluctuations. Commodity contract financial instruments were valued primarily based on prices and other relevant information observable in market transactions involving identical or comparable assets or liabilities including both forward and spot prices for commodities. All commodity financial instruments were valued as a Level 2 under the fair value measurements hierarchy.

Foreign Currency Contracts

We enter into forward sales and purchase contracts to manage currency risk resulting from purchase and sale commitments denominated in foreign currencies. Foreign currency contract financial instruments were valued primarily based on relevant information observable in market transactions involving identical or comparable assets or liabilities including both forward and spot prices for currencies. All foreign currency contract financial instruments were valued as a Level 2 under the fair value measurements hierarchy.

Financial Instruments

The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximated fair values due to the short-term maturities of these instruments. Since our long-term debt instruments may not be actively traded, the inputs used to measure the fair value of our long-term debt are based on current market rates for debt of similar risk and maturities and is classified as Level 2 in the fair value measurement hierarchy. As of September 30, 2024, December 31, 2023 and September 30, 2023, the fair value measurements of debt were $2,887.5 million, $2,626.2 million and $2,666.9 million, respectively.

Nonrecurring Fair Value Measurements

In addition to assets and liabilities that are recorded at fair value on a recurring basis, we record assets and liabilities at fair value on a nonrecurring basis as required by ASC 820. There were no assets or liabilities measured at fair value on a nonrecurring basis as of September 30, 2024, December 31, 2023 or September 30, 2023.

ITEM 2.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

BUSINESS BACKGROUND

Olin Corporation (Olin) is a Virginia corporation, incorporated in 1892, having its principal executive offices in Clayton, MO. We are a leading vertically integrated global manufacturer and distributor of chemical products and a leading U.S. manufacturer of ammunition. Our operations are concentrated in three business segments: Chlor Alkali Products and Vinyls,

25

Epoxy and Winchester. All of our business segments are capital-intensive manufacturing businesses. The Chlor Alkali Products and Vinyls segment manufactures and sells chlorine and caustic soda, ethylene dichloride and vinyl chloride monomer, methyl chloride, methylene chloride, chloroform, carbon tetrachloride, perchloroethylene, hydrochloric acid, hydrogen, bleach products and potassium hydroxide. The Epoxy segment produces and sells a full range of epoxy materials and precursors, including aromatics (acetone and phenol), allyl chloride, epichlorohydrin, liquid epoxy resins, solid epoxy resins and systems and growth products such as converted epoxy resins and additives. The Winchester segment produces and sells sporting ammunition, reloading components, small caliber military ammunition and components, industrial cartridges and clay targets.

EXECUTIVE SUMMARY

Overview

Net (loss) income for the three and nine months ended September 30, 2024, was $(24.9) million and $97.9 million, respectively, compared to $104.1 million and $407.3 million, for the prior year periods, respectively. The decrease of $129.0 million and $309.4 million, respectively, in net (loss) income from the prior year periods was primarily due to a decline in operating results across our Chemicals businesses. The operating results from our Winchester segment were lower for the three months ended September 30, 2024 but were higher for the nine months ended September 30, 2024 compared to the comparable prior year periods. Net income for the nine months ended September 30, 2023 also reflects a gain of $27.0 million for the sale of our domestic private trucking fleet and operations. Diluted net (loss) income per share was $(0.21) and $0.81 for the three and nine months ended September 30, 2024, respectively, compared to $0.82 and $3.12 in the prior year periods, respectively, a decrease of $1.03 and $2.31 per share.

Chlor Alkali Products and Vinyls reported segment income was $45.3 million and $221.2 million for the three and nine months ended September 30, 2024, respectively. Chlor Alkali Products and Vinyls segment results were lower than the comparable prior year periods due to the impact of Hurricane Beryl and lower pricing, primarily caustic soda. The nine months ended September 30, 2024 benefited from lower raw material and operating costs, and costs associated with products purchased from other parties, compared to last year. The Chlor Alkali and Vinyls segment results for the three and nine months ended September 30, 2023 were negatively impacted by higher costs and reduced profit from lost sales of $25.3 million and $104.2 million, respectively, associated with operating issues related to a 2023 second quarter maintenance turnaround at our vinyl chloride monomer plant at the Freeport, TX facility.

Epoxy reported a segment loss of $42.8 million and $57.6 million for the three and nine months ended September 30, 2024, respectively. Epoxy segment results for the three months ended September 30, 2024 were lower than the comparable prior year period primarily due to the impact of Hurricane Beryl, partially offset by lower raw material and operating costs. Epoxy segment results for the nine months ended September 30, 2024 were lower than the comparable prior year period primarily due to lower product pricing and the impact of Hurricane Beryl, partially offset by increased volumes and lower raw material and operating costs.

Winchester reported segment income of $53.4 million and $195.9 million for the three and nine months ended September 30, 2024, respectively. Winchester segment results for the three months ended September 30, 2024 were lower than the comparable prior year period due to higher commodity and operating costs, including propellant costs. Winchester segment results for the nine months ended September 30, 2024 were higher than the comparable prior year period due to higher sales volumes, which included White Flyer results, partially offset by higher commodity and operating costs, including propellant costs. Higher international military sales, military project revenue, and White Flyer sales were partially offset by lower commercial ammunition sales.

Liquidity and Share Repurchases

During the nine months ended September 30, 2024, we repurchased and retired 4.9 million shares of common stock at a total value of $256.8 million. As of September 30, 2024, we had $742.0 million of remaining authorized common stock to be repurchased under our 2022 Repurchase Authorization Program.

During the nine months ended September 30, 2024, we had net borrowings of $216.7 million with $282.0 million borrowed under our Senior Revolving Credit Facility, which was partially utilized to repay $70.0 million of tax-exempt variable-rate bonds, and $11.3 million under our Receivables Financing Agreement.

26

Other Items

On July 10, 2024, we announced a temporary disruption of operations at our Freeport, TX, facility as a result of Hurricane Beryl. In response to this disruption, we declared a system-wide force majeure for our Chlor Alkali Products & Vinyls products and aromatics shipments for our Epoxy segment. This disruption was a result of hurricane-related damage to Olin facilities in Freeport, TX, impacting Olin’s normal production and logistics capabilities including access to power, raw materials, and other essential feedstocks and services. During the third quarter, we safely returned many Freeport, TX plants to operation and on August 28, 2024, we lifted the system wide force majeure on Chlor Alkali Products and Vinyls products. However, persistent operating limitations necessitated an additional outage, which we commenced in late September and successfully completed during October.

The third quarter 2024 results included a negative pretax impact of $109.4 million associated with Hurricane Beryl for incremental costs to restore operations, unabsorbed fixed manufacturing costs, and reduced profit from lost sales. The Hurricane Beryl impact included in our Chlor Alkali Products and Vinyls and Epoxy segment results was $76.7 million and $32.7 million, respectively. We expect a residual fourth quarter Hurricane Beryl impact of approximately $25 million in our Chemicals businesses’ results.

Epoxy segment results in 2024 continue to be impacted by significant exports out of Asia into the European and North American markets, negatively impacting pricing and volumes. On April 3, 2024, we announced the filing of anti-dumping and countervailing duty petitions against China, India, South Korea, Taiwan and Thailand with the U.S. Department of Commerce and the U.S. International Trade Commission relating to certain epoxy resins, as part of the U.S. Epoxy Resin Producers Ad Hoc Coalition. The petitions were filed in response to large volumes of low-priced imports of epoxy resins into the U.S. from the subject countries over the past three years that have injured U.S. domestic epoxy resin producers.

On July 1, 2024, we announced the initiation of an anti-dumping proceeding by the European Commission against China, the Republic of Korea, Taiwan and Thailand concerning low-priced imports of epoxy resins into the European Union (EU), as a result of a complaint lodged by the Ad Hoc Coalition of Epoxy Resin Producers. The complaint alleges that exporting producers in the four targeted countries have injured the European epoxy resin producers by selling their products on the EU market at unfairly low prices that significantly undercut the prices of European producers.

During 2024, the U.S. Army awarded Winchester a contract for the construction of the Next Generation Squad Weapon (NGSW) manufacturing facility at Lake City Army Ammunition Plant. The project will be the first new manufacturing plant built at the Lake City facility in decades. The new manufacturing facility will provide safe, reliable, and advanced NGSW ammunition to the U.S. warfighter. Winchester will manage all aspects of the government-funded construction project, which commenced in the second quarter of 2024.

Three Months Ended September 30, 2024 Compared to Three Months Ended September 30, 2023

Sales for the three months ended September 30, 2024 were $1,589.5 million compared to $1,671.4 million in the same period last year, a decrease of $81.9 million, or 5%. Chlor Alkali Products and Vinyls sales decreased by $98.0 million primarily due to lower pricing, primarily caustic soda. Epoxy sales decreased by $36.5 million, primarily due to lower sales volumes, primarily as a result of Hurricane Beryl. Winchester sales increased by $52.6 million, primarily due to third quarter 2024 sales from White Flyer and increased sales to international military customers and military project revenue, partially offset by lower commercial ammunition sales.

Gross margin decreased $134.6 million for the three months ended September 30, 2024 compared to the prior year. Chlor Alkali Products and Vinyls gross margin decreased by $117.7 million primarily due to the impact of Hurricane Beryl and lower pricing, primarily caustic soda. Epoxy gross margin decreased by $11.0 million primarily due to the impact of Hurricane Beryl, partially offset by lower raw material and operating costs. Winchester gross margin decreased by $6.9 million primarily due to higher commodity and operating costs, including propellant costs. Gross margin as a percentage of sales decreased to 8% in 2024 from 16% in 2023, across all segments.

Selling and administrative expenses for the three months ended September 30, 2024 were $111.7 million, an increase of $20.8 million from the prior year. The increase was primarily due to higher legal and legal-related settlement expense of $11.9 million, consulting and contract services of $2.3 million, and stock-based compensation expense of $2.2 million, which includes mark-to-market adjustments. Selling and administrative expenses as a percentage of sales increased to 7% in 2024 from 5% in 2023.

Restructuring charges for the three months ended September 30, 2024 and 2023 were $7.9 million and $11.9 million, respectively. Restructuring charges were primarily associated with our 2023 actions to reconfigure our global Epoxy asset footprint to optimize the most productive and cost effective assets to support our strategic operating model, which resulted in pretax restructuring charges of $6.3 million and $8.6 million for the three months ended September 30, 2024 and 2023, respectively.

Interest expense increased by $2.2 million for the three months ended September 30, 2024 from the prior year, primarily due to higher average interest rates.

28

Non-operating pension income includes all components of pension and other postretirement net periodic benefit (income) cost, other than service costs. Non-operating pension income was higher for the three months ended September 30, 2024 primarily due to a decrease in the discount rate used to determine interest costs, partially offset by higher actuarial losses recognized to income.

The effective tax rate for the three months ended September 30, 2024 included a net $2.9 million tax expense, primarily associated with a change in tax contingencies and remeasurement of deferred taxes due to an increase in our state effective tax rates, partially offset by a benefit from prior year tax positions. Excluding these items, the effective tax rate for the three months ended September 30, 2024 of 11.5% was lower than the 21.0% U.S. federal statutory rate primarily due to state income tax, foreign income inclusions and an increase in the estimated annual effective tax rate, partially offset by favorable permanent salt depletion deductions. The effective tax rate for the three months ended September 30, 2023 included a net $7.2 million tax benefit, primarily associated with stock-based compensation and prior year tax positions, partially offset by an expense from a change in tax contingencies. Excluding these items, the effective tax rate for the three months ended September 30, 2023 of 23.2% was higher than the 21.0% U.S. federal statutory rate primarily due to state income tax and an increase in the valuation allowance related to losses in foreign jurisdictions, partially offset by favorable permanent salt depletion deductions and foreign income taxes.

Nine Months Ended September 30, 2024 Compared to Nine Months Ended September 30, 2023

Sales for the nine months ended September 30, 2024 were $4,868.8 million compared to $5,218.4 million in the same period last year, a decrease of $349.6 million, or 7%. Chlor Alkali Products and Vinyls sales decreased by $412.5 million primarily due to lower pricing, primarily caustic soda. Epoxy sales decreased by $72.0 million, primarily due to lower product pricing, partially offset by increased sales volumes. Winchester sales increased by $134.9 million, primarily due to 2024 sales from White Flyer and increased sales to international military customers and military project revenue.

Gross margin decreased $402.2 million for the nine months ended September 30, 2024 compared to the prior year. Chlor Alkali Products and Vinyls gross margin decreased by $360.9 million primarily due to lower pricing, primarily caustic soda, partially offset by lower costs. Epoxy gross margin decreased by $50.9 million primarily due to lower product pricing, partially offset by increased volumes. Winchester gross margin increased by $4.1 million primarily due to higher sales volume, including White Flyer, partially offset by higher commodity and operating costs, including propellant costs. Gross margin as a percentage of sales decreased to 12% in 2024 from 19% in 2023, across all segments.

Selling and administration expenses for the nine months ended September 30, 2024 were $308.2 million, an increase of $4.3 million from the prior year. The increase was primarily due to higher legal and legal-related settlement expense of $13.6 million, partially offset by a favorable foreign currency impact of $3.0 million and lower stock-based compensation expense of $2.7 million, which includes mark-to-market adjustments. Selling and administration expenses as a percentage of sales was 6% for both the nine months ended September 30, 2024 and 2023.

Restructuring charges for the nine months ended September 30, 2024 and 2023 were $23.0 million and $92.0 million, respectively. The decrease was primarily due to charges associated with our 2023 actions to reconfigure our global Epoxy asset footprint to optimize the most productive and cost effective assets to support our strategic operating model, which resulted in pretax restructuring charges of $15.6 million and $79.7 million for the nine months ended September 30, 2024 and 2023, respectively.

Other operating income for the nine months ended September 30, 2023 included a gain of $27.0 million for the sale of our domestic private trucking fleet and operations.

Interest expense increased by $5.7 million for the nine months ended September 30, 2024 from the prior year primarily due to higher average interest rates.

Non-operating pension income includes all components of pension and other postretirement net periodic benefit (income) cost, other than service costs. Non-operating pension income was higher for the nine months ended September 30, 2024 primarily due to a decrease in the discount rate used to determine interest costs, partially offset by higher actuarial losses recognized to income.

The effective tax rate for the nine months ended September 30, 2024 included a net $0.4 million tax benefit, primarily associated with stock-based compensation, U.S. Federal tax credits purchased at a discount, and a benefit from prior year tax positions, partially offset by a change in tax contingencies and remeasurement of deferred taxes due to an increase in our state effective tax rates. Excluding these items, the effective tax rate for the nine months ended September 30, 2024 of 28.2% was higher than the 21.0% U.S. federal statutory rate primarily due to state income tax and foreign income inclusions, partially offset by favorable permanent salt depletion deductions. The effective tax rate for the nine months ended September 30, 2023 included a net $24.4 million tax benefit, primarily associated with stock-based compensation and prior year tax positions, partially offset by an expense from a change in tax contingencies. Excluding these items, the effective tax rate for

29

the nine months ended September 30, 2023 of 24.1% was higher than the 21.0% U.S. federal statutory rate primarily due to state income tax and an increase in the valuation allowance related to losses in foreign jurisdictions, partially offset by favorable permanent salt depletion deductions and foreign income taxes.

SEGMENT RESULTS

We define segment results as income (loss) before interest expense, interest income, other operating income (expense), non-operating pension income, other income and income taxes. We have three operating segments: Chlor Alkali Products and Vinyls, Epoxy and Winchester. The three operating segments reflect the organization used by our management for purposes of allocating resources and assessing performance. Chlorine and caustic soda used in our Epoxy segment is transferred at cost from the Chlor Alkali Products and Vinyls segment.

Chlor Alkali Products and Vinyls

Three Months Ended September 30, 2024 Compared to Three Months Ended September 30, 2023

Chlor Alkali Products and Vinyls sales for the three months ended September 30, 2024 were $871.6 million compared to $969.6 million for the same period in 2023, a decrease of $98.0 million, or 10%. The sales decrease was primarily due to lower pricing, primarily caustic soda.

Chlor Alkali Products and Vinyls segment income was $45.3 million for the three months ended September 30, 2024 compared to $172.3 million for the same period in 2023. The decrease in segment results of $127.0 million was due to the negative impact of Hurricane Beryl resulting in incremental costs to restore operations, unabsorbed fixed manufacturing costs, and reduced profit from lost sales ($76.7 million), lower pricing ($79.5 million), primarily caustic soda, and higher raw material and operating costs ($17.6 million), partially offset by increased volumes ($43.6 million) and lower costs associated with product purchased from other parties ($3.2 million). Chlor Alkali Products and Vinyls third quarter 2023 segment results were negatively impacted by a maintenance turnaround and subsequent operating issues with the vinyl chloride monomer plant at the Freeport, TX facility, resulting in higher costs and reduced profit from lost sales. Chlor Alkali Products and Vinyls segment results included depreciation and amortization expense of $106.5 million and $107.6 million for the three months ended September 30, 2024 and 2023, respectively.

30

Nine Months Ended September 30, 2024 Compared to Nine Months Ended September 30, 2023

Chlor Alkali Products and Vinyls sales for the nine months ended September 30, 2024 were $2,676.5 million compared to $3,089.0 million for the same period in 2023, a decrease of $412.5 million, or 13%. The sales decrease was primarily due to lower pricing, primarily caustic soda, partially offset by increased sales volumes associated with products purchased from other parties.

Chlor Alkali Products and Vinyls segment income was $221.2 million for the nine months ended September 30, 2024 compared to $598.3 million for the same period in 2023. The decrease in segment results of $377.1 million was due to lower pricing ($476.1 million), primarily caustic soda, the negative impact of Hurricane Beryl resulting in incremental costs to restore operations, unabsorbed fixed manufacturing costs, and reduced profit from lost sales ($76.7 million), and an unfavorable product mix ($39.9 million), partially offset by lower costs associated with products purchased from other parties ($120.9 million) and lower raw material and operating costs ($94.7 million). Chlor Alkali Products and Vinyls third quarter 2023 segment results were negatively impacted by a maintenance turnaround and subsequent operating issues with the vinyl chloride monomer plant at the Freeport, TX facility, resulting in higher costs and reduced profit from lost sales. Chlor Alkali Products and Vinyls segment results included depreciation and amortization expense of $319.1 million and $335.3 million for the nine months ended September 30, 2024 and 2023, respectively.

Epoxy

Three Months Ended September 30, 2024 Compared to Three Months Ended September 30, 2023

Epoxy sales for the three months ended September 30, 2024 were $285.1 million compared to $321.6 million for the same period in 2023, a decrease of $36.5 million, or 11%. The sales decrease was due to lower sales volumes ($35.4 million), primarily as a result of Hurricane Beryl and an unfavorable effect of foreign currency translation ($2.1 million), partially offset by higher product prices ($1.0 million).

Epoxy segment loss was $42.8 million for the three months ended September 30, 2024 compared to segment loss of $28.8 million for the same period in 2023. The decrease in segment results of $14.0 million was due to the negative impact of Hurricane Beryl resulting in incremental costs to restore operations, unabsorbed fixed manufacturing costs, and reduced profit from lost sales ($32.7 million) and decreased volumes ($1.3 million), partially offset by lower raw material and operating costs ($20.0 million). A significant percentage of our Euro denominated sales are of products manufactured within Europe. As a result, the impact of foreign currency translation on revenue is primarily offset by the impact of foreign currency translation on raw materials and manufacturing costs also denominated in Euros. Epoxy segment results included depreciation and amortization expense of $13.7 million and $14.7 million for the three months ended September 30, 2024 and 2023, respectively.

Nine Months Ended September 30, 2024 Compared to Nine Months Ended September 30, 2023

Epoxy sales for the nine months ended September 30, 2024 were $944.1 million compared to $1,016.1 million for the same period in 2023, a decrease of $72.0 million, or 7%. The sales decrease was due to lower product prices ($132.6 million) and an unfavorable effect of foreign currency translation ($4.5 million), partially offset by increased sales volumes ($65.1 million), which were negatively impacted by Hurricane Beryl.

Epoxy segment loss was $57.6 million for the nine months ended September 30, 2024 compared to segment loss of $7.9 million for the same period in 2023. The decrease in segment results of $49.7 million was due to lower product prices ($133.4 million), which continues to be impacted by significant exports out of Asia into the European and North American markets, and the negative impact of Hurricane Beryl resulting in incremental costs to restore operations, unabsorbed fixed manufacturing costs, and reduced profit from lost sales ($32.7 million), partially offset by increased volumes and improved product mix ($82.2 million) and lower raw material and operating costs ($34.2 million). A significant percentage of our Euro denominated sales are of products manufactured within Europe. As a result, the impact of foreign currency translation on revenue is primarily offset by the impact of foreign currency translation on raw materials and manufacturing costs also denominated in Euros. Epoxy segment results included depreciation and amortization expense of $40.6 million and $44.4 million for the nine months ended September 30, 2024 and 2023, respectively.

Three Months Ended September 30, 2024 Compared to Three Months Ended September 30, 2023

Winchester sales were $432.8 million for the three months ended September 30, 2024 compared to $380.2 million for the same period in 2023, an increase of $52.6 million, or 14%. The increase was due to higher sales to domestic and international military customers ($43.5 million), higher sales to commercial customers ($10.4 million), partially offset by lower sales to law enforcement agencies ($1.3 million). Commercial sales were primarily impacted by 2024 sales from White Flyer, partially

31

offset by lower ammunition volumes.

Winchester segment income was $53.4 million for the three months ended September 30, 2024 compared to $64.5 million for the same period in 2023, a decrease of $11.1 million. The decrease in segment results was due to higher commodity and operating costs ($17.2 million), including propellant costs, partially offset by higher sales volumes ($4.1 million), which includes White Flyer, and higher product pricing ($2.0 million). Winchester segment income included depreciation and amortization expense of $8.5 million and $6.6 million for the three months ended September 30, 2024 and 2023, respectively.

Nine Months Ended September 30, 2024 Compared to Nine Months Ended September 30, 2023

Winchester sales were $1,248.2 million for the nine months ended September 30, 2024 compared to $1,113.3 million for the same period in 2023, an increase of $134.9 million, or 12%. The increase was due to higher sales to commercial customers ($75.3 million) and higher sales to domestic and international military customers ($70.1 million), partially offset by lower sales to law enforcement agencies ($10.5 million). Commercial sales were primarily impacted by 2024 sales from White Flyer.

Winchester segment income was $195.9 million for the nine months ended September 30, 2024 compared to $190.2 million for the same period in 2023, an increase of $5.7 million. The increase in segment results was due to higher sales volumes ($27.1 million), which includes White Flyer, partially offset by higher commodity and operating costs ($16.8 million), including propellant costs, and lower product pricing ($4.6 million). Winchester segment income included depreciation and amortization expense of $24.7 million and $19.1 million for the nine months ended September 30, 2024 and 2023, respectively.

Corporate/Other

Three Months Ended September 30, 2024 Compared to Three Months Ended September 30, 2023

For the three months ended September 30, 2024, charges to income for environmental investigatory and remedial activities were $7.2 million compared to $6.9 million for the three months ended September 30, 2023. These charges related primarily to expected future investigatory and remedial activities associated with past manufacturing operations and former waste disposal sites.

For the three months ended September 30, 2024, other corporate and unallocated costs were $25.9 million compared to $22.9 million for the three months ended September 30, 2023, an increase of $3.0 million. The increase was primarily due to higher stock-based compensation ($2.2 million), which includes mark-to-market adjustments, and higher legal and legal-related settlement expenses ($1.6 million).

Nine Months Ended September 30, 2024 Compared to Nine Months Ended September 30, 2023

For the nine months ended September 30, 2024, charges to income for environmental investigatory and remedial activities were $19.4 million compared to $23.1 million for the nine months ended September 30, 2023. These charges related primarily to expected future investigatory and remedial activities associated with past manufacturing operations and former waste disposal sites.

For the nine months ended September 30, 2024, other corporate and unallocated costs were $68.7 million compared to $79.6 million for the nine months ended September 30, 2023, a decrease of $10.9 million. The decrease was primarily due to lower variable incentive compensation costs ($6.3 million), which includes mark-to-market adjustments on stock-based compensation expense, and a favorable foreign currency impact ($3.0 million).

Restructurings

In connection with the previously announced Epoxy Optimization Plan, for the three months ended September 30, 2024 and 2023, we recorded restructuring charges of $6.3 million and $8.6 million, respectively, and for the nine months ended September 30, 2024 and 2023, we recorded restructuring charges of $15.6 million and $79.7 million, respectively. We expect to incur additional restructuring charges through 2025 of approximately $10 million related to these actions.

For the three months ended September 30, 2024 and 2023, we incurred charges of $1.6 million and $3.3 million, respectively, and for the nine months ended September 30, 2024 and 2023, we incurred charges of $7.4 million and $12.3 million, respectively, associated with other previously disclosed restructuring plans. We expect to incur additional restructuring charges through 2027 of approximately $40 million related to these actions. Discussion on our restructuring activity, including a description of each plan, is referenced under Item 1, within Note 4, “Restructuring Charges.” Pretax restructuring charges related to our actions include facility exit costs, lease and other contract termination costs, employee severance and related benefits costs and the write-off of equipment and facilities.

OUTLOOK

In the third quarter 2024, our Chemicals businesses were able to safely return multiple Freeport, TX, plants to operation after Hurricane Beryl, completing our efforts during October. In the third quarter 2024, we incurred a negative $109.4 million impact from Hurricane Beryl, and we anticipate a residual negative fourth quarter impact of approximately $25 million on our Chemicals businesses’ results. Excluding the Hurricane Beryl impact, we expect our Chemicals businesses’ fourth quarter 2024 results to seasonally decline from the third quarter 2024.

We expect our Winchester business fourth quarter results to decline from third quarter levels with seasonally weaker commercial ammunition demand and inventory destocking by our retail customers.

Other corporate and unallocated costs in 2024 are expected to be comparable with the $106.3 million in 2023.

During 2024, we anticipate environmental expenses in the $25 million to $30 million range, compared to $23.7 million in 2023.

We expect non-operating pension income in 2024 to be similar to the $24.0 million in 2023. Based on our plan assumptions and estimates, we will not be required to make any cash contributions to our domestic qualified defined benefit pension plan in 2024. We have several international qualified defined benefit pension plans for which we anticipate cash contributions of less than $5 million in 2024.

In 2024, we currently expect our capital spending to be approximately $200 million, including approximately $10 million of additional capital associated with Hurricane Beryl. Our payments under other long-term supply contracts for energy modernization on the U.S. Gulf Coast will be $58.6 million as we made our final payment during the third quarter 2024. We expect 2024 depreciation and amortization expense to be approximately $525 million.

We currently believe the 2024 effective tax rate will be in the 25% to 30% range and cash taxes paid to be approximately $110 million.

ENVIRONMENTAL MATTERS

Environmental provisions charged to income, which are included in costs of goods sold, were $7.2 million and $6.9 million for the three months ended September 30, 2024 and 2023, respectively, and were $19.4 million and $23.1 million for the nine months ended September 30, 2024 and 2023, respectively.

The following table summarizes the environmental liability activity:

	Nine Months Ended September 30,
	2024		2023
Environmental Liabilities	($ in millions)
Balance at beginning of year	$	153.6	$	146.6
Charges to income	19.4		23.1
Remedial and investigatory spending	(18.8)		(16.2)
Balance at end of period	$	154.2	$	153.5

Environmental investigatory and remediation activities spending was associated with former waste disposal sites and past manufacturing operations. Spending in 2024 for investigatory and remedial efforts, the timing of which is subject to regulatory approvals and other uncertainties, is estimated to be approximately $30 million. Cash outlays for remedial and investigatory activities associated with former waste disposal sites and past manufacturing operations were not charged to income, but instead, were charged to reserves established for such costs identified and expensed to income in prior periods. Associated costs of investigatory and remedial activities are provided for in accordance with generally accepted accounting principles governing probability and the ability to reasonably estimate future costs. Our ability to estimate future costs depends on whether our investigatory and remedial activities are in preliminary or advanced stages. With respect to unasserted claims, we accrue liabilities for costs that, in our experience, we expect to incur to protect our interests against those unasserted claims. Our accrued liabilities for unasserted claims amounted to $11.7 million at September 30, 2024. With respect to asserted claims, we accrue liabilities based on remedial investigation, feasibility study, remedial action and operation, maintenance and monitoring (OM&M) expenses that, in our experience, we expect to incur in connection with the asserted claims. Required site OM&M expenses are estimated and accrued in their entirety for required periods not exceeding 30 years, which reasonably approximates the typical duration of long-term site OM&M. Charges to income for investigatory and remedial efforts may be material to our operating results in 2024.

33

The condensed balance sheets included reserves for future environmental expenditures to investigate and remediate known sites amounting to $154.2 million, $153.6 million and $153.5 million at September 30, 2024, December 31, 2023 and September 30, 2023, respectively, of which $122.2 million, $121.6 million and $128.5 million, respectively, were classified as other noncurrent liabilities. These amounts do not take into account any discounting of future expenditures or any consideration of insurance recoveries or advances in technology. These liabilities are reassessed periodically to determine if environmental circumstances have changed and/or remediation efforts and our estimate of related costs have changed. As a result of these reassessments, future charges to income may be made for additional liabilities.

Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, developments at sites resulting from investigatory studies, advances in technology, changes in environmental laws and regulations and their application, changes in regulatory authorities, the scarcity of reliable data pertaining to identified sites, the difficulty in assessing the involvement and financial capability of other Potentially Responsible Parties (PRPs), our ability to obtain contributions from other parties and the lengthy time periods over which site remediation occurs. It is possible that some of these matters (the outcomes of which are subject to various uncertainties) may be resolved unfavorably to us, which could materially adversely affect our financial position or results of operations.

LEGAL MATTERS AND CONTINGENCIES

Discussion of legal matters and contingencies can be referred to under Item 1, within Note 18, “Commitments and Contingencies.”

Operating Activities

For the nine months ended September 30, 2024, cash provided by operating activities decreased by $196.2 million from the nine months ended September 30, 2023, primarily due to a decrease in operating results, partially offset by a smaller increase in working capital compared with the prior year. For the nine months ended September 30, 2024, working capital increased $58.7 million compared to an increase of $172.6 million for the nine months ended September 30, 2023. Accounts payable and accrued liabilities decreased $77.2 million from December 31, 2023, primarily as a result of timing of payments during the third quarter of 2024.

Investing Activities

Capital spending was $144.1 million for the nine months ended September 30, 2024, compared to $173.0 million for the comparable period in 2023. Our capital spending forecast represents normal capital spending to maintain our current operating facilities. For the full year 2024, we expect our capital spending to be approximately $200 million, including $10 million of additional capital associated with Hurricane Beryl. We expect 2024 depreciation and amortization expense to be approximately $525 million.

34

For the nine months ended September 30, 2024, payments under other long-term supply contracts were $58.6 million for energy modernization on the U.S. Gulf Coast. Our payments for this project were completed in the third quarter.

For the nine months ended September 30, 2023, we received $28.5 million of cash proceeds for the sale of our domestic private trucking fleet and operations.

Financing Activities

For the nine months ended September 30, 2024 and 2023, we had long-term debt borrowings, net of repayments, of $216.7 million and $206.6 million, respectively.

For the nine months ended September 30, 2024 and 2023, 4.9 million and 10.8 million shares, respectively, of common stock were repurchased and retired at a total value of $256.8 million and $595.1 million, respectively.

We issued 0.9 million and 0.8 million shares representing stock options exercised for the nine months ended September 30, 2024 and 2023, respectively, with a total value of $22.6 million and $22.3 million, respectively. For the nine months ended September 30, 2024, we withheld and paid $10.5 million for employee taxes on share-based payment arrangements.

For the nine months ended September 30, 2023, we received $44.1 million of cash contributions from noncontrolling interests for BWA.

The percent of total debt to total capitalization increased to 58.0% as of September 30, 2024 from 54.1% as of December 31, 2023, primarily as a result of a higher level of debt outstanding and lower shareholders’ equity, primarily due to common stock repurchases partially offset by our operating results.

In the first three quarters of 2024 and 2023, we paid a quarterly dividend of $0.20 per share. Dividends paid for the nine months ended September 30, 2024 and 2023, were $70.9 million and $76.6 million, respectively. On October 24rd, 2024, our Board of Directors declared a dividend of $0.20 per share on our common stock, payable on December 13th, 2024, to shareholders of record on November 14th, 2024.

The payment of cash dividends is subject to the discretion of our Board of Directors and will be determined in light of then-current conditions, including our earnings, our operations, our financial condition, our capital requirements and other factors deemed relevant by our Board of Directors. In the future, our Board of Directors may change our dividend policy, including the frequency or amount of any dividend, in light of then-existing conditions.

Liquidity and Other Financing Arrangements

Our principal sources of liquidity are from cash and cash equivalents, cash flow from operations and borrowings under our Senior Revolving Credit Facility, Receivables Financing Agreement (as defined below) and AR Facilities (as defined below). Additionally, we believe that we have access to the high-yield debt and equity markets.

We maintain a $1,550.0 million senior credit facility (Senior Credit Facility) which includes a senior term loan facility with aggregate commitments of $350.0 million (Term Loan Facility) and a senior revolving credit facility with aggregate commitments of $1,200.0 million (Senior Revolving Credit Facility). The Term Loan Facility was fully drawn on the closing date with the proceeds of the Term Loan Facility used to refinance the loans and commitments outstanding under the existing facility. The Term Loan Facility requires principal amortization payments which began on March 31, 2023 at a rate of 0.625% per quarter through the end of 2024, increasing to 1.250% per quarter thereafter until maturity. The maturity date for the Senior Credit Facility is October 11, 2027.

The Senior Revolving Credit Facility includes a $100.0 million letter of credit subfacility. At September 30, 2024, we had $849.6 million available under our $1,200.0 million Senior Revolving Credit Facility because we had $350.0 million borrowed under the facility and issued $0.4 million of letters of credit. During 2024, the Senior Revolving Credit Facility borrowings were partially utilized to repay $50.0 million of Go Zone and $20.0 million of Recovery Zone tax-exempt variable-rate bonds.

We were in compliance with all covenants and restrictions under all our outstanding credit agreements as of September 30, 2024, and no event of default had occurred that would permit the lenders under our outstanding credit agreements to accelerate the debt if not cured. In the future, our ability to generate sufficient operating cash flows, among other factors, will determine the amounts available to be borrowed under these facilities. As a result of our restrictive covenant related to the net leverage ratio, the maximum additional borrowings available to us could be limited in the future. The limitation, if an amendment or waiver from our lenders is not obtained, could restrict our ability to borrow the maximum amounts available under the Senior Revolving Credit Facility and the Receivables Financing Agreement. As of September 30, 2024, there were no covenants or other restrictions that limited our ability to borrow.

35

We believe, based on current and projected levels of cash flow from our operations, together with our cash and cash equivalents on hand and the availability to borrow under our Senior Revolving Credit Facility and AR Facilities, we have sufficient liquidity to meet our short-term and long-term needs, to make required payments of interest on our debt, fund our operating needs, working capital and our capital expenditure requirements, and comply with the financial ratios in our debt agreements.

On July 28, 2022, our Board of Directors authorized a share repurchase program for the purchase of shares of common stock at an aggregate price of up to $2.0 billion. This program will terminate upon the purchase of $2.0 billion of common stock.

For the nine months ended September 30, 2024, 4.9 million shares of common stock have been repurchased and retired at a total value of $256.8 million. As of September 30, 2024, 24.2 million shares of common stock have been repurchased and retired at a total value of $1,258.0 million under the 2022 Repurchase Authorization program, and $742.0 million of common stock remained authorized to be repurchased under the program.

We maintain a $425.0 million Receivables Financing Agreement (Receivables Financing Agreement) that is scheduled to mature on October 14, 2025. Under the Receivables Financing Agreement, our eligible trade receivables are used for collateralized borrowings and continue to be serviced by us. In addition, the Receivables Financing Agreement incorporates the net leverage ratio covenant that is contained in the Senior Credit Facility. As of September 30, 2024, December 31, 2023 and September 30, 2023, we had $339.8 million, $328.5 million and $350.0 million, respectively, drawn under the agreement. As of September 30, 2024, $473.9 million of our trade receivables were pledged as collateral and we had $0.3 million additional borrowing capacity under the Receivables Financing Agreement, which was limited by our borrowing base.

Olin also has trade accounts receivable factoring arrangements (AR Facilities) and pursuant to the terms of the AR Facilities, certain of our domestic subsidiaries may sell their accounts receivable up to a maximum of $134.5 million and certain of our foreign subsidiaries may sell their accounts receivable up to a maximum of €16.5 million. We will continue to service the outstanding accounts sold. These receivables qualify for sales treatment under ASC 860 and, accordingly, the proceeds are included in net cash provided by operating activities in the condensed statements of cash flows.

The following table summarizes the AR facilities activity:

	Nine Months Ended September 30,
	2024		2023
AR Facilities	($ in millions)
Balance at beginning of period	$	63.3	$	111.8
Gross receivables sold	528.5		749.5
Payments received from customers on sold accounts	(539.5)		(788.6)
Balance at end of period	$	52.3	$	72.7

The factoring discount paid under the AR Facilities is recorded as interest expense on the condensed statements of operations. The factoring discount was $0.8 million and $1.3 million for the three months ended September 30, 2024 and 2023, respectively, and $2.9 million and $3.8 million for the nine months ended September 30, 2024 and 2023, respectively. The agreements are without recourse and therefore no recourse liability has been recorded as of September 30, 2024.

36

At September 30, 2024, we had total letters of credit of $167.3 million outstanding, of which $0.4 million were issued under our Senior Revolving Credit Facility. The letters of credit were used to support certain long-term debt obligations, workers compensation insurance policies, plant closure and post-closure obligations, international payment obligations and international pension funding requirements.

Our current debt structure is used to fund our business operations. As of September 30, 2024, we had long-term borrowings, including the current installment, of $2,889.5 million, of which $1,110.4 million were at variable rates. Included within long-term borrowings on the condensed balance sheets were deferred debt issuance costs and unamortized bond original issue discount of $14.1 million as of September 30, 2024. Commitments from banks under our Senior Revolving Credit Facility and AR Facilities are additional sources of liquidity.

We have registered an undetermined number of securities with the SEC, so that, from time-to-time we may issue debt securities, preferred stock and/or common stock and associated warrants in the public market under that registration statement.

Credit Ratings

We receive ratings from three independent credit rating agencies: Fitch Ratings (Fitch), Moody's Investor Service (Moody's) and Standard & Poor's (S&P). The following table summarizes our credit ratings as of September 30, 2024:

Credit Rating Agency	Long-term Rating	Outlook
Fitch Ratings	BBB-	Stable
Moody’s Investors Service	Ba1	Stable
Standard & Poor’s	BB+	Stable

On August 8, 2024, S&P affirmed Olin’s BB+ rating and revised its outlook from positive to stable. On June 24, 2024, Moody’s affirmed Olin’s Ba1 rating and stable outlook. On March 14, 2024, Fitch affirmed Olin’s BBB- rating and stable outlook.

Contractual Obligations

Purchasing commitments are utilized in our normal course of business for our projected needs. We have supply contracts with various third parties for certain raw materials including ethylene, electricity, propylene and benzene. These agreements are maintained through long-term cost based contracts that provide us with a reliable supply of key raw materials. There have been no material changes in our contractual obligations and commitments as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023, other than those which occur in the ordinary course of business.

New Accounting Pronouncements

Discussion of new accounting pronouncements can be referred to under Item 1, within Note 2, “Recent Accounting Pronouncements.”

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk in the normal course of our business operations due to our purchases of certain commodities, our ongoing investing and financing activities and our operations that use foreign currencies. The risk of loss can be assessed from the perspective of adverse changes in fair values, cash flows and future earnings. We have established policies and procedures governing our management of market risks and the use of financial instruments to manage exposure to such risks.

Energy costs, including electricity and natural gas, and certain raw materials used in our production processes are subject to price volatility. Depending on market conditions, we may enter into futures contracts, forward contracts, commodity swaps and put and call option contracts in order to reduce the impact of commodity price fluctuations. As of September 30, 2024, we maintained open positions on commodity contracts with a notional value totaling $207.2 million ($191.0 million at December 31, 2023, and $207.5 million at September 30, 2023). Assuming a hypothetical 10% increase in commodity prices which are currently hedged, as of September 30, 2024, we would experience a $20.7 million ($19.1 million at December 31, 2023 and $20.8 million at September 30, 2023) increase in our cost of inventory purchased, which would be substantially offset by a corresponding increase in the value of related hedging instruments.

We transact business in various foreign currencies other than the USD which exposes us to movements in exchange rates which may impact revenue and expenses, assets and liabilities and cash flows. Our significant foreign currency exposure is denominated with European currencies, primarily the Euro, although exposures also exist in other currencies of Asia Pacific, Latin America, Middle East and Africa. For all derivative positions, we evaluated the effects of a 10% shift in exchange rates

37

between those currencies and the USD, holding all other assumptions constant. Unfavorable currency movements of 10% would negatively affect the fair values of the derivatives held to hedge currency exposures by $14.9 million. These unfavorable changes would generally have been offset by favorable changes in the values of the underlying exposures.

We are exposed to changes in interest rates primarily as a result of our investing and financing activities. Our current debt structure is used to fund business operations, and commitments from banks under our Senior Revolving Credit Facility and AR Facilities are additional sources of liquidity. As of September 30, 2024, December 31, 2023 and September 30, 2023, we had long-term borrowings, including current installments and finance lease obligations, of $2,889.5 million, $2,670.1 million and $2,790.1 million, respectively, of which $1,110.4 million, $893.7 million and $1,014.3 million at September 30, 2024, December 31, 2023 and September 30, 2023, respectively, were issued at variable rates. Included within long-term borrowings on the condensed balance sheets were deferred debt issuance costs and unamortized bond original issue discount.

Assuming no changes in the $1,110.4 million of variable-rate debt levels from September 30, 2024, we estimate that a hypothetical change of 100-basis points in the secured overnight financing rate (SOFR) would impact annual interest expense by $11.1 million.

If the actual changes in commodities, foreign currency, or interest pricing is substantially different than expected, the net impact of commodity risk, foreign currency risk, or interest rate risk on our cash flow may be materially different than that disclosed above.

We do not enter into any derivative financial instruments for speculative purposes.

ITEM 4. CONTROLS AND PROCEDURES

Our Chief Executive Officer and our Chief Financial Officer evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2024. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of such date, our disclosure controls and procedures were effective to ensure that information Olin is required to disclose in the reports that it files or submits with the SEC under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, and to ensure that information we are required to disclose in such reports is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

There have been no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
