OLIN CORPORATION AND CONSOLIDATED SUBSIDIARIES
Notes to Condensed Financial Statements
(Unaudited)
NOTE 1. DESCRIPTION OF BUSINESS
Olin Corporation (Olin, the Company, we or our) 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 formulated solutions 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.
Basis of Presentation
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, 2024.
NOTE 2. RECENT ACCOUNTING PRONOUNCEMENTS
In November 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which expands the disclosure requirements in the notes to the financial statements on certain costs and expenses on an interim and annual basis. The new requirements are effective for the Company’s annual reporting periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027, with the option to early adopt at any time before the effective date. ASU 2024-03 requires adoption on a prospective basis, with the option for retrospective application. While the ASU implements further disclosure requirements, it does not change how an entity calculates and/or records its expenses, and it will have no impact on the Company’s consolidated financial statements. We are currently evaluating the impact of the standard on our disclosures.
In December 2023, the FASB issued 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.
NOTE 3. ACQUISITIONS
On April 18, 2025, Olin acquired AMMO, Inc.’s small caliber ammunition manufacturing assets for total consideration of $55.8 million, subject to normal post-closing adjustments. The acquisition, which includes AMMO Inc.’s brass shellcase capabilities and its 185,000 square foot production facility located in Manitowoc, WI, is included in Olin’s Winchester segment. The acquisition was financed with cash on hand. We recorded the preliminary aggregate excess purchase price over the fair value of identifiable tangible assets acquired and liabilities assumed, which included a preliminary allocation of $2.0 million of goodwill to our Winchester segment. The preliminary total assets acquired, excluding goodwill, and liabilities assumed amounted to $60.0 million and $6.2 million respectively. The acquisition is not material and therefore supplemental pro forma financial information is not provided.

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.

Senior Notes and Senior Credit Facilities
On March 14, 2025, Olin issued $600.0 million aggregate principal amount of 6.625% senior notes due April 1, 2033 (2033 Notes), in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended. Interest on the 2033 Notes began accruing from March 14, 2025 and is paid semi-annually beginning on October 1, 2025, and every six months thereafter.
On March 14, 2025, Olin entered into a $1,850.0 million senior credit facility (2025 Senior Credit Facility), which increased the borrowing limit of our then-existing $1,550.0 million senior credit facility (2022 Senior Credit Facility) by $300.0 million and extended the maturity date from October 11, 2027 to March 14, 2030. The 2025 Senior Credit Facility includes a term loan facility with aggregate commitments of $650.0 million (2025 Term Loan Facility) and a revolving credit facility with aggregate commitments of $1,200.0 million (2025 Revolving Credit Facility).
The 2025 Term Loan Facility replaced Olin’s then-existing $350.0 million term loan facility (2022 Term Loan Facility, and collectively with the new 2025 Term Loan Facility, the Term Loan Facilities). The 2025 Term Loan Facility requires principal amortization payments beginning on June 30, 2025 at a rate of 0.625% per quarter through March 31, 2027, increasing to 1.250% per quarter thereafter, until maturity, and was fully drawn on the closing date.
The 2025 Revolving Credit Facility replaced Olin’s then-existing $1,200.0 million revolving credit facility (2022 Revolving Credit Facility, and collectively with the new 2025 Revolving Credit Facility, the Revolving Credit Facilities). The 2025 Revolving Credit Facility includes a $100.0 million letter of credit subfacility. At June 30, 2025, we had $1,164.6 million available under our 2025 Revolving Credit Facility because we had $35.0 million borrowed under the facility and issued $0.4 million of letters of credit.
Proceeds from the 2033 Notes, together with borrowings under the 2025 Senior Credit Facility, were used to redeem the $108.6 million 2025 Notes, redeem the $500.0 million 2027 Notes, refinance the then-existing 2022 Senior Credit Facility, comprised of $505.0 million of borrowings under the 2022 Revolving Credit Facility and $332.5 million of borrowings under the 2022 Term Loan Facility, and pay related fees and expenses.
13
We were in compliance with all covenants and restrictions under all our outstanding debt agreements as of June 30, 2025, and no event of default had occurred under any of our outstanding debt agreements that would permit the acceleration of 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 2025 Senior Credit Facility and the 2024 Receivables Financing Agreement (defined below). As of June 30, 2025, there were no covenants or other restrictions that limited our ability to borrow.
Receivables Financing Agreements
On November 20, 2024, we entered into a $500.0 million receivables financing agreement (2024 Receivables Financing Agreement), which increased the borrowing limit of our then-existing $425.0 million receivables financing agreement (2022 Receivables Financing Agreement) by $75.0 million and extended the maturity date from October 14, 2025 to November 19, 2027 (collectively, the Receivables Financing Agreements).
Under the Receivables Financing Agreements, our eligible trade receivables are used for collateralized borrowings and continue to be serviced by us. In addition, the Receivables Financing Agreements incorporate the net leverage ratio covenant that is contained in the 2025 Senior Credit Facility. As of June 30, 2025, December 31, 2024 and June 30, 2024, we had $465.0 million, $475.0 million and $298.8 million, respectively, drawn under the Receivables Financing Agreements. As of June 30, 2025, $609.3 million of our trade receivables were pledged as collateral and we had $35.0 million of additional borrowing capacity under the 2024 Receivables Financing Agreement.
As part of the 2024 Receivables Financing Agreement, we terminated our then-existing trade accounts receivable factoring arrangements (AR Facilities), under which certain of our domestic and international subsidiaries could sell their accounts receivable. These receivables had qualified for sales treatment under ASC 860 “Transfers and Servicing” and, accordingly, the proceeds were included in net cash provided by operating activities in the consolidated statements of cash flows.

Other Financing

For the six months ended June 30, 2025, we paid debt issuance costs of $12.0 million associated with the 2033 Notes and the 2025 Senior Credit Facility.
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 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.

NOTE 12. INCOME TAXES
The effective tax rate for the three months ended June 30, 2025 included a net $3.3 million tax benefit, primarily associated with U.S. federal investment tax credits and a release of valuation allowances on domestic state net operating losses
15
and tax credits, partially offset by an expense from prior year tax positions and a change in tax contingencies. Excluding these items, the effective tax rate for the three months ended June 30, 2025 of 10.3% was lower than the 21.0% U.S. federal statutory rate primarily due to state income tax, favorable permanent salt depletion deductions, non-taxable exchange rate results and a favorable foreign rate differential, partially offset by foreign income inclusions. The effective tax rate for the three months ended June 30, 2024 included a net $0.6 million tax benefit, primarily associated with stock-based compensation and U.S. federal tax credits purchased at a discount, partially offset by an expense from prior year tax positions and a change in tax contingencies. Excluding these items, the effective tax rate for the three months ended June 30, 2024 of 25.8% 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 six months ended June 30, 2025 included a net $2.9 million tax benefit primarily associated with U.S. federal investment tax credits and a release of valuation allowances on domestic state net operating losses and tax credits, partially offset by an expense from prior year tax positions and a change in tax contingencies. Excluding these items, the effective tax rate for the six months ended June 30, 2025 of 4.3% was lower than the 21.0% U.S. federal statutory rate primarily due to state income tax, favorable permanent salt depletion deductions, non-taxable exchange rate results and a favorable foreign rate differential, partially offset by foreign income inclusions. The effective tax rate for the six months ended June 30, 2024 included a net $3.3 million tax benefit, primarily associated with stock-based compensation and U.S. federal tax credits purchased at a discount, partially offset by an expense from prior year tax positions and a change in tax contingencies. Excluding these items, the effective tax rate for the six months ended June 30, 2024 of 25.6% 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.
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. In the second quarter of 2025, Olin realized $22.0 million of investment tax credits via its Hidrogenii joint venture interest and recorded a tax benefit of $2.6 million.
On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was enacted in the U.S. This act introduces significant changes to tax law and other areas affecting company operations, including items such as extensions of Tax Cuts and Jobs Act provisions, changes to business interest deductions, modifications to depreciation deductions and impacts on energy tax credits. While the effects of these tax law changes will not be reflected in interim or annual provisions for the period ended June 30, 2025, the Company is evaluating the potential impact of the OBBBA on its financial position, results of operations, and cash flows for future periods. Specific potential impacts that are being assessed include effects on future tax expense, cash flows from operations due to new deductions, or potential impacts on investment decisions. Further details on the impact of this legislation will be provided as the evaluation progresses.
As of June 30, 2025, we had $22.3 million of gross unrecognized tax benefits, which would have impacted the effective tax rate, if recognized. The amounts of unrecognized tax benefits were as follows:
| Six Months Ended June 30, | |||||||||||
| 2025 | 2024 | ||||||||||
| Unrecognized Tax Benefits | ($ in millions) | ||||||||||
| Balance at beginning of year | $ | 21.1 | $ | 50.3 | |||||||
| Increases for prior year tax positions | 1.5 | 2.7 | |||||||||
| Decreases for prior year tax positions | (0.2) | (0.4) | |||||||||
| Increases for current year tax positions | 0.7 | 0.7 | |||||||||
| Decreases due to tax settlements | (0.8) | (1.0) | |||||||||
| Foreign currency translation adjustments | — | (1.1) | |||||||||
| Balance at end of period | $ | 22.3 | $ | 51.2 | |||||||
As of June 30, 2025, we believe it is reasonably possible that our total amount of unrecognized tax benefits will decrease by approximately $9.5 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.
16
For our primary tax jurisdictions, the tax years that remain subject to examination are as follows:
| Tax Years | |||||
| U.S. federal income tax | 2020 - 2024 | ||||
| U.S. state income tax | 2015 - 2024 | ||||

NOTE 13. DEFINED CONTRIBUTION PLAN
The Company sponsors a defined contribution plan for qualifying domestic employees (Employee Retirement Savings Plan) and a supplemental executive retirement plan as follows:
Employee Retirement Savings Plan
We sponsor a defined contribution plan for qualifying domestic employees, for which the Company contributes between 5.0% and 7.0% 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.
We also match a percentage of our employees’ contributions (Company Match), which are invested in the same investment allocation as the employees’ contributions. Employees immediately vest in the Company Match.
Our contributions to the defined contribution plan were as follows:

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 | 2025 | 2024 | |||||||||
| Risk-free interest rate | 4.27 | % | 4.53 | % | |||||||
| Expected volatility of Olin common stock | 37 | % | 41 | % | |||||||
| Expected average volatility of peer companies | 35 | % | 37 | % | |||||||
| Average correlation coefficient of peer companies | 0.45 | 0.40 | |||||||||
| Expected life (years) | 3.0 | 3.0 | |||||||||
| Grant date fair value (TSR-based award) | $ | 27.46 | $ | 72.80 | |||||||
| Grant date fair value (net income-based award) | $ | 27.62 | $ | 54.07 | |||||||
| Performance share awards granted | 573,479 | 180,714 | |||||||||
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.
Restricted Stock Units
During the six months ended June 30, 2025 and 2024, Olin granted restricted stock units of 452,863 and 219,500, respectively, at a weighted average grant date fair value per share of $26.96 and $56.99, respectively. The fair value of each restricted stock unit was estimated on the date of grant using the current stock price. The awards typically vest ratably, on an annual basis, over three years, but not less than one year.
Stock Options
During the six months ended June 30, 2025, Olin granted no stock options. During the six months ended June 30, 2024, Olin granted stock options of 601,157 at a weighted-average grant date fair value per option of $24.79 and a weighted-average exercise price of $53.43. 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.
NOTE 15. SHAREHOLDERS’ EQUITY
On December 11, 2024, our Board of Directors approved a share repurchase program with a $1.3 billion authorization (2024 Repurchase Authorization). The Board of Directors previously authorized share repurchases with a $2.0 billion authorization on July 28, 2022 (2022 Repurchase Authorization). The 2024 Repurchase Authorization and 2022 Repurchase Authorization will terminate upon the purchase of $1.3 billion and $2.0 billion of common stock, respectively.
For the six months ended June 30, 2025 and 2024, 1.2 million and 3.9 million shares, respectively, of common stock were repurchased and retired at a total value of $30.3 million and $211.4 million, respectively. As of June 30, 2025, a cumulative total of 26.3 million shares of common stock have been repurchased and retired at a total value of $1,331.1 million under the 2022 Repurchase Authorization program, and $668.9 million of common stock remained authorized to be repurchased under the 2022 Repurchase Authorization program. As of June 30, 2025, there have been no repurchases under the 2024 Repurchase Authorization program and $1.3 billion remained available.
We issued less than 0.1 million and 0.8 million shares representing stock options exercised for the six months ended June 30, 2025 and 2024, respectively, with a total value of $1.9 million and $21.7 million, respectively.

NOTE 16. SEGMENT INFORMATION
The chief operating decision maker (CODM) is the individual, or group of individuals, who assess financial performance and determines resource allocation. Management has identified our Chief Executive Officer (CEO) as the CODM. In arriving at this conclusion, we considered that the individual who receives the relevant financial information, which is primarily provided in the form of segment operations reviews, is ultimately our CEO. Further, our CEO assesses the reasonableness of resource allocation, primarily in the form of capital allocation and budgetary analysis, and reviews segment results and resource allocation summaries prepared by segment management, consistent with their view of the business as a whole.
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, and includes the results of non-consolidated affiliates in segment results consistent with management’s monitoring of the operating segments. 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, and represents our reportable segments. Chlorine and caustic soda used in our Epoxy segment is transferred at cost from the Chlor Alkali Products and Vinyls segment.
19
Cost of goods sold at Corporate is primarily attributed to environmental expense. Other segment items for each reportable segment includes selling, general and administrative expenses and earnings (losses) from non-consolidated affiliates. Segment assets include only those assets which are directly identifiable to an operating segment. Assets in the corporate/other segment primarily include cash and cash equivalents, deferred taxes and other assets. Sales are attributed to geographic areas based on the customer location.

(1) For the three months ended June 30, 2025 and 2024, revenue recognized over time represented $94.4 million and $37.8 million, respectively, and for the six months ended June 30, 2025 and 2024, revenue recognized over time represented $152.9 million and $57.6 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 $155.2 million, $156.5 million and $155.3 million at June 30, 2025, December 31, 2024 and June 30, 2024, respectively, of which $125.2 million, $126.5 million and $123.3 million, respectively, were classified as other noncurrent liabilities.
Environmental provisions charged to income, which are included in costs of goods sold, were $4.8 million and $6.4 million for the three months ended June 30, 2025 and 2024, respectively, and $9.8 million and $12.2 million for the six months ended June 30, 2025 and 2024, 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, cash flows 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 June 30, 2025, December 31, 2024 and June 30, 2024, our condensed balance sheets included accrued liabilities for these other legal actions of $18.8 million, $19.7 million and $12.5 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, cash flows or results of operations. We had the following notional amounts of outstanding forward contracts to buy and sell foreign currency:

| Sell | 145.3 | 133.7 | 157.0 | ||||||||||||||
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:

As of June 30, 2025, 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, 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 June 30, 2025, we had open derivative contract positions through 2028. If all open futures contracts had been settled on June 30, 2025, we would have recognized a pretax gain of $10.2 million.
If commodity prices were to remain at June 30, 2025 levels, approximately $5.7 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.
24
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 June 30, 2025, December 31, 2024 and June 30, 2024.
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 effects of derivative instruments on our condensed statements of operations:
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.
25
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 June 30, 2025, December 31, 2024 and June 30, 2024, 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 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, 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 June 30, 2025, December 31, 2024 and June 30, 2024, the fair value measurements of debt were $2,989.0 million, $2,779.0 million and $2,717.3 million, respectively.
26
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 June 30, 2025, December 31, 2024 or June 30, 2024.
ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
BUSINESS BACKGROUND
Olin Corporation (Olin, the Company, we or our) 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 (EDC) 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 formulated solutions 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 six months ended June 30, 2025 was ($1.3) million, and $0.1 million, respectively, compared to $74.2 million and $122.8 million, for the prior year periods, respectively. The decrease of $75.5 million and $122.7 million, respectively, in net income from the prior year periods was primarily due to lower operating results across all of our business segments. Diluted net (loss) income per share was ($0.01) and $0.00 for the three and six months ended June 30, 2025, respectively, compared to $0.62 and $1.01 in the prior year periods, respectively.
Chlor Alkali Products and Vinyls reported segment income was $64.9 million and $143.2 million for the three and six months ended June 30, 2025, respectively. Chlor Alkali Products and Vinyls segment results were lower than the comparable prior year periods due to higher raw material and operating costs, including planned maintenance turnaround expenses, and lower pricing, primarily EDC, partially offset by higher volumes.
Epoxy reported a segment loss of $23.7 million and $52.1 million for the three and six months ended June 30, 2025, respectively. Epoxy segment results were lower than the comparable prior year periods primarily due to higher operating costs, including planned maintenance turnaround expenses, as product margins were comparable year over year. Global epoxy demand remains weak, and our U.S. and European Epoxy businesses remains significantly challenged by subsidized Asian competition. Our anti-dumping initiatives have provided limited benefits to date.
Winchester reported segment income of $25.0 million and $47.8 million for the three and six months ended June 30, 2025, respectively. Winchester segment results were lower than the comparable prior year periods due to decreased commercial ammunition sales volumes and pricing and higher raw material and operating costs, including commodity metal and propellant costs, partially offset by higher domestic and international military sales and military project revenue.
Liquidity and Share Repurchases
During the six months ended June 30, 2025, we repurchased and retired 1.2 million shares of common stock at a total value of $30.3 million. As of June 30, 2025, we had $1,968.9 million of remaining authorized common stock to be repurchased under our 2022 Repurchase Authorization and 2024 Repurchase Authorization (both defined below) programs.
On March 14, 2025, we issued $600.0 million aggregate principal amount of 6.625% senior notes due April 1, 2033 (2033 Notes), in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended.
On March 14, 2025, we entered into a new $1,850.0 million senior credit facility (2025 Senior Credit Facility), which increased the borrowing limit of our then-existing credit facility by $300.0 million and extended the maturity date from October 11, 2027 to March 14, 2030. Pursuant to the agreement, the aggregate principal amount under our term loan facility increased from $350.0 million to $650.0 million and the aggregate principal amount under our revolving credit facility remained at $1,200.0 million. The term loan was fully drawn on the closing date.
27
During the six months ended June 30, 2025, we had net borrowings of $159.8 million. Proceeds from the 2033 Notes, together with borrowings under the 2025 Senior Credit Facility, were used to redeem the $108.6 million 9.50% senior notes due 2025 (2025 Notes), redeem the $500.0 million 5.125% senior notes due 2027 (2027 Notes), refinance the then-existing $1,550.0 million senior credit facility (2022 Senior Credit Facility) comprised of $505.0 million of borrowings under the prior revolving credit facility and $332.5 million of borrowings under the prior term loan facility, and pay related fees and expenses.
International Trade
The ultimate impact of tariffs and trade flows remains highly uncertain. While we are continuing to monitor the situation, as of the date of this filing, the direct impact from current tariffs have not been significant to our chemicals businesses. Our chemicals businesses generally source and sell where we produce. An exception to this would be potential retaliatory tariffs on caustic soda and EDC exports, which could alter the economics rapidly within the respective countries. Additionally, although Winchester buys most metals locally, we still realize tariff-related price inflation on the domestic price of steel, aluminum and copper.
Other Items
On April 18, 2025, Olin acquired AMMO, Inc.’s small caliber ammunition manufacturing assets for total consideration of $55.8 million, subject to normal post-closing adjustments. The acquisition, which included AMMO Inc.’s brass shellcase capabilities and its 185,000 square foot production facility located in Manitowoc, WI, is included in Olin’s Winchester segment. The acquisition was financed with cash on hand.

Three Months Ended June 30, 2025 Compared to Three Months Ended June 30, 2024
Sales for the three months ended June 30, 2025 were $1,758.3 million compared to $1,644.0 million in the same period last year, an increase of $114.3 million, or 7%. Chlor Alkali Products and Vinyls sales increased by $59.2 million primarily due to higher volumes. Winchester sales increased by $41.6 million, primarily due to increased sales to military customers and military project revenue, partially offset by lower commercial ammunition sales. Epoxy sales increased by $13.5 million, primarily due to higher volumes, partially offset by lower pricing.
28
Gross margin decreased $99.7 million for the three months ended June 30, 2025 compared to the prior year period. Winchester gross margin decreased by $48.2 million primarily due to lower commercial sales volumes and pricing. Chlor Alkali Products and Vinyls gross margin decreased by $34.1 million primarily due to higher raw material and operating costs, including planned maintenance turnaround expenses, partially offset by higher volumes. Epoxy gross margin decreased by $18.9 million primarily due to higher operating costs, including planned maintenance turnaround expenses. Gross margin as a percentage of sales decreased to 8% during the three months ended June 30, 2025 from 14% during the three months ended June 30, 2024.
Selling and administration expenses for the three months ended June 30, 2025 were $95.2 million, an increase of $0.6 million from the prior year period. The increase was primarily due to higher stock-based compensation expense of $7.3 million, which includes mark-to-market adjustments, partially offset by favorable foreign currency impact of $4.9 million. Selling and administration expenses as a percentage of sales was 5% and 6% for the three months ended June 30, 2025 and 2024, respectively.
Restructuring charges for the three months ended June 30, 2025 and 2024 were $7.4 million and $6.8 million, respectively. Restructuring charges include facility exit costs, lease and other contract termination costs, and employee severance and related benefits costs
Losses of non-consolidated affiliates relate to Olin’s equity share of the Hidrogenii, LLC joint venture.
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 lower for the three months ended June 30, 2025 compared to the prior year period, primarily due to a lower assumption for the long-term rate of return on plan assets.
The effective tax rate for the three months ended June 30, 2025 included a net $3.3 million tax benefit, primarily associated with U.S. federal investment tax credits and a release of valuation allowances on domestic state net operating losses and tax credits, partially offset by an expense from prior year tax positions and a change in tax contingencies. Excluding these items, the effective tax rate for the three months ended June 30, 2025 of 10.3% was lower than the 21.0% U.S. federal statutory rate primarily due to state income tax, favorable permanent salt depletion deductions, non-taxable exchange rate results and a favorable foreign rate differential, partially offset by foreign income inclusions. The effective tax rate for the three months ended June 30, 2024 included a net $0.6 million tax benefit, primarily associated with stock-based compensation and U.S. federal tax credits purchased at a discount, partially offset by an expense from prior year tax positions and a change in tax contingencies. Excluding these items, the effective tax rate for the three months ended June 30, 2024 of 25.8% 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.
Six Months Ended June 30, 2025 Compared to Six Months Ended June 30, 2024
Sales for the six months ended June 30, 2025 were $3,402.5 million compared to $3,279.3 million in the same period last year, an increase of $123.2 million, or 4%.

Epoxy gross margin decreased by $34.5 million primarily due to higher operating costs, including planned maintenance turnaround expenses. Chlor Alkali Products and Vinyls gross margin decreased by $30.2 million primarily due to higher raw material and operating costs, including planned maintenance turnaround expenses, and lower pricing, primarily EDC, partially offset by higher volumes. Gross margin as a percentage of sales decreased to 8% during the six months ended June 30, 2025 from 14% during the six months ended June 30, 2024.
Selling and administration expenses for the six months ended June 30, 2025 were $196.2 million, a decrease of $0.3 million from the prior year period. The decrease was primarily due to a favorable foreign currency impact of $9.6 million, partially offset by higher legal and legal-related settlement expense of $4.6 million and higher stock-based compensation expense of $1.0 million, which includes mark-to-market adjustments. Selling and administration expenses as a percentage of sales was 6% for both the six months ended June 30, 2025 and 2024.

Excluding these items, the effective tax rate for the six months ended June 30, 2025 of 4.3% was lower than the 21.0% U.S. federal statutory rate primarily due to state income tax, favorable permanent salt depletion deductions, non-taxable exchange rate results and a favorable foreign rate differential, partially offset by foreign income inclusions. The effective tax rate for the six months ended June 30, 2024 included a net $3.3 million tax benefit, primarily associated with stock-based compensation and U.S. federal tax credits purchased at a discount, partially offset by an expense from prior year tax positions and a change in tax contingencies. Excluding these items, the effective tax rate for the six months ended June 30, 2024 of 25.6% 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.
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, and includes the results of non-consolidated affiliates in segment results consistent with management’s monitoring of the operating segments. 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.

Epoxy sales for the three months ended June 30, 2025 were $331.2 million compared to $317.7 million for the same period in 2024, an increase of $13.5 million, or 4%. The sales increase was due to higher volumes ($24.6 million) and a favorable effect of foreign currency translation ($5.0 million), partially offset by lower product pricing ($16.1 million).
Epoxy segment loss was $23.7 million for the three months ended June 30, 2025 compared to segment loss of $3.0 million for the same period in 2024. The decrease in segment results of $20.7 million was due to higher operating costs ($24.4 million), including planned maintenance turnaround expenses, and lower product pricing ($16.1 million), offset by lower raw material costs ($18.1 million), primarily benzene and propylene, and increased volumes ($1.7 million), which included an unfavorable product mix. A significant percentage of our Euro denominated sales are from 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 $13.1 million and $13.4 million for the three months ended June 30, 2025 and 2024, respectively.
Six Months Ended June 30, 2025 Compared to Six Months Ended June 30, 2024
Epoxy sales for the six months ended June 30, 2025 were $662.9 million compared to $659.0 million for the same period in 2024, an increase of $3.9 million, or 1%. The sales increase was due to higher volumes ($24.6 million), partially offset by lower product pricing ($18.4 million) and an unfavorable effect of foreign currency translation ($2.3 million).
Epoxy segment loss was $52.1 million for the six months ended June 30, 2025 compared to segment loss of $14.8 million for the same period in 2024. The decrease in segment results of $37.3 million was due to higher operating costs ($41.7 million), including planned maintenance turnaround expenses, and lower product pricing ($18.4 million), offset by lower raw material costs ($23.2 million), primarily benzene and propylene, and an unfavorable product mix ($0.4 million). A significant percentage of our Euro denominated sales are from 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 $25.9 million and $26.9 million for the six months ended June 30, 2025 and 2024, respectively.

Winchester
Three Months Ended June 30, 2025 Compared to Three Months Ended June 30, 2024
Winchester sales were $447.6 million for the three months ended June 30, 2025 compared to $406.0 million for the same period in 2024, an increase of $41.6 million, or 10%. The sales increase was due to higher sales to military customers and military project revenue ($102.0 million), partially offset by lower sales to commercial customers ($55.2 million) and law enforcement agencies ($5.2 million).
Winchester segment income was $25.0 million for the three months ended June 30, 2025 compared to $70.3 million for the same period in 2024, a decrease of $45.3 million. The decrease in segment results was due to lower sales volumes ($21.4 million), lower product pricing ($12.7 million), and higher raw material and operating costs ($11.2 million), including commodity metal and propellant costs. Winchester segment income included depreciation and amortization expense of $7.9 million and $8.3 million for the three months ended June 30, 2025 and 2024, respectively.
Six Months Ended June 30, 2025 Compared to Six Months Ended June 30, 2024
Winchester sales were $835.6 million for the six months ended June 30, 2025 compared to $815.4 million for the same period in 2024, an increase of $20.2 million, or 2%. The sales increase was due to higher sales to military customers and military project revenue ($168.7 million), partially offset by lower sales to commercial customers ($142.1 million) and law enforcement agencies ($6.4 million).
Winchester segment income was $47.8 million for the six months ended June 30, 2025 compared to $142.5 million for the same period in 2024, a decrease of $94.7 million. The decrease in segment results was due to lower sales volumes ($46.1 million), higher raw material and operating costs ($27.8 million), including commodity metal and propellant costs, and lower product pricing ($20.8 million). Winchester segment income included depreciation and amortization expense of $17.4 million and $16.2 million for the six months ended June 30, 2025 and 2024, respectively.
Corporate/Other
Three Months Ended June 30, 2025 Compared to Three Months Ended June 30, 2024
For the three months ended June 30, 2025, charges to income for environmental investigatory and remedial activities were $4.8 million compared to $6.4 million for the three months ended June 30, 2024. 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 June 30, 2025, other corporate and unallocated costs were $19.9 million compared to $17.0 million for the three months ended June 30, 2024, an increase of $2.9 million. The increase was primarily due to higher variable incentive compensation costs ($9.0 million), which includes mark-to-market adjustments on stock-based compensation expense, partially offset by a favorable foreign currency impact ($5.0 million).
Six Months Ended June 30, 2025 Compared to Six Months Ended June 30, 2024
For the six months ended June 30, 2025, charges to income for environmental investigatory and remedial activities were $9.8 million compared to $12.2 million for the six months ended June 30, 2024. These charges related primarily to expected future investigatory and remedial activities associated with past manufacturing operations and former waste disposal sites.
For the six months ended June 30, 2025, other corporate and unallocated costs were $39.9 million compared to $42.8 million for the six months ended June 30, 2024, a decrease of $2.9 million. The decrease was primarily due to a favorable foreign currency impact ($9.7 million), partially offset by higher variable incentive compensation costs ($4.4 million), which includes mark-to-market adjustments on stock-based compensation expense.
Restructurings
Pretax restructuring charges related to our restructuring and optimization efforts 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 for the three and six months ended June 30, 2025 and 2024, were as follows:

OUTLOOK
We expect our third quarter 2025 operating results to continue to be impacted by challenging markets with potential higher costs and general uncertainty related to tariffs. Despite these macroeconomic headwinds, we anticipate our Chemicals businesses operating results will experience seasonally stronger demand, and lower maintenance turnaround expenses from second quarter 2025 levels. In the third quarter 2025, we expect our Winchester business to experience increased military demand and seasonally stronger commercial sales volumes, partially offset by sequentially higher raw material costs, including tariff-driven commodity metal costs. Overall, we expect Olin’s third quarter 2025 operating results to be comparable or slightly higher than our second quarter 2025 levels.
Other corporate and unallocated costs in 2025 are expected to be higher than the $90.1 million in 2024.
During 2025, we anticipate environmental expenses in the $25 million to $35 million range, compared to $30.2 million in 2024.
We expect non-operating pension income in 2025 to be lower than the $26.0 million in 2024. 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 2025. We have several international qualified defined benefit pension plans for which we anticipate cash contributions of less than $5 million in 2025.
In 2025, we currently expect our capital spending to be in the $200 million to $220 million range. We expect 2025 depreciation and amortization expense to be approximately $525 million.
We currently believe the 2025 effective tax rate will be in the 25% to 35% range. We expect cash taxes paid to be approximately $175 million, primarily for earnings in foreign jurisdictions, including the previously deferred international tax payments expected to be made in 2025.
ENVIRONMENTAL MATTERS
Environmental provisions charged to income, which are included in costs of goods sold, were $4.8 million and $6.4 million for the three months ended June 30, 2025 and 2024, respectively, and $9.8 million and $12.2 million for the six months ended June 30, 2025 and 2024, respectively.
The following table summarizes the environmental liability activity:
| Six Months Ended June 30, | |||||||||||
| 2025 | 2024 | ||||||||||
| Environmental Liabilities | ($ in millions) | ||||||||||
| Balance at beginning of year | $ | 156.5 | $ | 153.6 | |||||||
| Charges to income | 9.8 | 12.2 | |||||||||
| Remedial and investigatory spending | (11.1) | (10.5) | |||||||||
| Balance at end of period | $ | 155.2 | $ | 155.3 | |||||||
Environmental investigatory and remediation activities spending was associated with former waste disposal sites and past manufacturing operations. Spending in 2025 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,
33
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 $11.6 million at June 30, 2025. 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 2025.
The condensed balance sheets included reserves for future environmental expenditures to investigate and remediate known sites amounting to $155.2 million, $156.5 million and $155.3 million at June 30, 2025, December 31, 2024 and June 30, 2024, respectively, of which $125.2 million, $126.5 million and $123.3 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.

Operating Activities
For the six months ended June 30, 2025, cash provided by operating activities decreased by $45.3 million from the six months ended June 30, 2024, primarily due to a decrease in operating results, partially offset by a smaller increase in working capital compared with the prior year period. For the six months ended June 30, 2025, working capital increased $112.4 million compared to an increase of $166.3 million for the six months ended June 30, 2024. Receivables increased $34.1 million, primarily due to the timing of sales during the second quarter 2025 compared to the fourth quarter 2024. Inventories increased $51.8 million from December 31, 2024, which reflects normal seasonal growth. Income taxes payable, net of income taxes receivable, decreased by $124.3 million from December 31, 2024 primarily due to timing of international tax payments. Accounts payable and accrued liabilities increased $108.2 million from December 31, 2024, primarily as a result of timing of payments during the first half of 2025.

Investing Activities
Capital spending was $92.4 million for the six months ended June 30, 2025, compared to $100.8 million for the comparable period in 2024. For the full year 2025, we expect our capital spending to be in the $200 million to $220 million range. Our capital spending forecast represents normal capital spending to maintain our current operating facilities. We expect 2025 depreciation and amortization expense to be in the $525 million range.
On April 18, 2025, Olin acquired AMMO, Inc.’s small caliber ammunition manufacturing assets for total consideration of $55.8 million. The acquisition was financed with cash on hand.
For the six months ended June 30, 2024, payments under other long-term supply contracts were $46.7 million for energy modernization on the U.S. Gulf Coast. Our payments for this project were completed in the third quarter of 2024.
Financing Activities

For the six months ended June 30, 2025 and 2024, 1.2 million and 3.9 million shares, respectively, of common stock were repurchased and retired at a total value of $30.3 million and $211.4 million, respectively.
We issued less than 0.1 million and 0.8 million shares representing stock options exercised for the six months ended June 30, 2025 and 2024, respectively, with a total value of $1.9 million and $21.7 million, respectively. For the six months ended June 30, 2024, we withheld and paid $10.5 million for employee taxes on share-based payment arrangements.
The percentage of total debt to total capitalization increased to 60.1% as of June 30, 2025 from 58.0% as of December 31, 2024, primarily as a result of a higher level of debt outstanding.
In the first and second quarters of 2025 and 2024, we paid a quarterly dividend of $0.20 per share. Dividends paid for the six months ended June 30, 2025 and 2024, were $46.0 million and $47.6 million, respectively.
Liquidity and Other Financing Arrangements
Our principal sources of liquidity are from cash and cash equivalents, cash flow from operations and borrowings under our 2025 Revolving Credit Facility and our 2024 Receivables Financing Agreement (as defined below). Additionally, we believe that we have access to the high-yield debt and equity markets.

On March 14, 2025, Olin issued $600.0 million aggregate principal amount of 6.625% senior notes due April 1, 2033 (2033 Notes), in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended. Interest on the 2033 Notes began accruing from March 14, 2025 and is paid semi-annually beginning on October 1, 2025, and every six months thereafter.
On March 14, 2025, Olin entered into a $1,850.0 million senior credit facility (2025 Senior Credit Facility), which increased the borrowing limit of our then-existing $1,550.0 million senior credit facility (2022 Senior Credit Facility) by $300.0 million and extended the maturity date from October 11, 2027 to March 14, 2030. The 2025 Senior Credit Facility includes a term loan facility with aggregate commitments of $650.0 million (2025 Term Loan Facility) and a revolving credit facility with aggregate commitments of $1,200.0 million (2025 Revolving Credit Facility).
The 2025 Term Loan Facility replaced Olin’s then-existing $350.0 million term loan facility (2022 Term Loan Facility, and collectively with the new 2025 Term Loan Facility, the Term Loan Facilities). The 2025 Term Loan Facility requires principal amortization payments beginning on June 30, 2025 at a rate of 0.625% per quarter through March 31, 2027, increasing to 1.250% per quarter thereafter, until maturity, and was fully drawn on the closing date.
The 2025 Revolving Credit Facility replaced Olin’s then-existing $1,200.0 million revolving credit facility (2022 Revolving Credit Facility, and collectively with the new 2025 Revolving Credit Facility, the Revolving Credit Facilities). The 2025 Revolving Credit Facility includes a $100.0 million letter of credit subfacility. At June 30, 2025, we had $1,164.6 million available under our 2025 Revolving Credit Facility because we had $35.0 million borrowed under the facility and issued $0.4 million of letters of credit.
Proceeds from the 2033 Notes, together with borrowings under the 2025 Senior Credit Facility, were used to redeem the $108.6 million 2025 Notes, redeem the $500.0 million 2027 Notes, refinance the then-existing 2022 Senior Credit Facility, comprised of $505.0 million of borrowings under the 2022 Revolving Credit Facility and $332.5 million of borrowings under the 2022 Term Loan Facility, and pay related fees and expenses.
We were in compliance with all covenants and restrictions under all our outstanding debt agreements as of June 30, 2025, and no event of default had occurred under any of our outstanding debt agreements that would permit the acceleration of 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 2025 Senior Credit Facility and the 2024 Receivables Financing Agreement (defined below). As of June 30, 2025, there were no covenants or other restrictions that limited our ability to borrow.
On November 20, 2024, we entered into a $500.0 million receivables financing agreement (2024 Receivables Financing Agreement), which increased the borrowing limit of our then-existing $425.0 million receivables financing agreement (2022 Receivables Financing Agreement) by $75.0 million and extended the maturity date from October 14, 2025 to November 19, 2027 (collectively, the Receivables Financing Agreements).
Under the Receivables Financing Agreements, our eligible trade receivables are used for collateralized borrowings and continue to be serviced by us. In addition, the Receivables Financing Agreements incorporate the net leverage ratio covenant that is contained in the 2025 Senior Credit Facility. As of June 30, 2025, December 31, 2024 and June 30, 2024, we had $465.0 million, $475.0 million and $298.8 million, respectively, drawn under the Receivables Financing Agreements. As of June 30, 2025, $609.3 million of our trade receivables were pledged as collateral and we had $35.0 million of additional borrowing capacity under the 2024 Receivables Financing Agreement.
At June 30, 2025, we had total letters of credit of $161.4 million outstanding, of which $0.4 million were issued under our 2025 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 June 30, 2025, we had long-term borrowings, including the current installment, of $2,996.7 million, of which $1,231.8 million were at variable rates. Included within long-term borrowings on the condensed balance sheets were deferred debt issuance costs of $19.7 million as of June 30, 2025.
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 2025 Revolving Credit Facility and 2024 Receivables Financing Agreement, we have the ability to access 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 and other covenants and restrictions in our debt agreements.
36
On December 11, 2024, our Board of Directors approved a share repurchase program with a $1.3 billion authorization (2024 Repurchase Authorization). The Board of Directors previously authorized share repurchases with a $2.0 billion authorization on July 28, 2022 (2022 Repurchase Authorization). The 2024 Repurchase Authorization and 2022 Repurchase Authorization will terminate upon the purchase of $1.3 billion and $2.0 billion of common stock, respectively.
For the six months ended June 30, 2025, 1.2 million shares of common stock were repurchased and retired at a total value of $30.3 million. As of June 30, 2025, a cumulative total of 26.3 million shares of common stock have been repurchased and retired at a total value of $1,331.1 million under the 2022 Repurchase Authorization program, and $1,968.9 million of common stock remained authorized to be repurchased under the 2022 Repurchase Authorization and 2024 Repurchase Authorization programs.
We have registered the sale of an undetermined number of securities with the SEC, so that, from time-to-time, we may issue, offer and sell debt securities, preferred stock, common stock and/or warrants to purchase any such securities pursuant to a 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 June 30, 2025:
| Credit Rating Agency | Long-term Rating | Outlook | ||||||||||||
| Fitch Ratings | BBB- | Stable | ||||||||||||
| Moody’s Investors Service | Ba1 | Stable | ||||||||||||
| Standard & Poor’s | BB+ | Stable | ||||||||||||
On June 3, 2025, Moody’s affirmed Olin’s Ba1 rating and stable outlook. On March 12, 2025, Fitch affirmed Olin’s BBB- rating and stable outlook. On August 8, 2024, S&P affirmed Olin’s BB+ rating and revised its outlook from positive to stable.
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, 2024, other than those which occur in the ordinary course of business.
Critical Accounting Estimates
Refer to “Critical Accounting Estimates” contained in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2024 for a complete discussion of our critical accounting estimates. There have been no material changes to our critical accounting estimates since our Annual Report on Form 10-K for the year ended December 31, 2024.
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 June 30, 2025, we maintained open positions on commodity contracts with a notional value totaling $170.0 million ($204.5 million at December 31, 2024, and $208.1 million at June 30, 2024). Assuming a hypothetical 10% increase in commodity prices which are currently hedged, as of June 30, 2025, we would experience a $17.0 million ($20.5 million at December 31, 2024 and $20.8
37
million at June 30, 2024) 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 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 $14.5 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 2025 Revolving Credit Facility and our 2024 Receivables Financing Agreement are additional sources of liquidity. As of June 30, 2025, December 31, 2024 and June 30, 2024, we had long-term borrowings, including current installments and finance lease obligations, of $2,996.7 million, $2,842.2 million and $2,910.9 million, respectively, of which $1,231.8 million, $1,063.4 million and $1,132.6 million at June 30, 2025, December 31, 2024 and June 30, 2024, 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 $1,231.8 million of variable-rate debt levels from June 30, 2025, we estimate that a hypothetical change of 100-basis points in the secured overnight financing rate (SOFR) would impact annual interest expense by $12.3 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 June 30, 2025. 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 SEC’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 June 30, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
