Olin Announces Fourth Quarter 2023 Results
Highlights
•Fourth quarter 2023 net income of $52.9 million, or $0.43 per diluted share
•Quarterly adjusted EBITDA of $210.1 million
•Share repurchases of $711.3 million in 2023
•Expect 2024 adjusted EBITDA to improve from 2023
Clayton, MO, January 25, 2024 – Olin Corporation (NYSE: OLN) announced financial results for the fourth quarter ended December 31, 2023. Fourth quarter 2023 reported net income was $52.9 million, or $0.43 per diluted share, which compares to fourth quarter 2022 reported net income of $196.6 million, or $1.43 per diluted share. Fourth quarter 2023 adjusted EBITDA of $210.1 million excludes depreciation and amortization expense of $128.5 million, insurance recoveries of $22.0 million, and restructuring income of $2.4 million. Fourth quarter 2022 adjusted EBITDA was $441.8 million. Sales in the fourth quarter 2023 were $1,614.6 million, compared to $1,977.0 million in the fourth quarter 2022. Full year 2023 reported net income was $460.2 million, or $3.57 per diluted share, which compares to full year 2022 reported net income of $1,326.9 million, or $8.94 per diluted share.
Scott Sutton, Chairman, President, and Chief Executive Officer, said, “Through the challenging economic environment of 2023, Olin successfully demonstrated our unique winning model by delivering $1.3 billion of adjusted EBITDA and corresponding cash flows enabling the 2023 repurchase of approximately 10% of our outstanding shares. As we are confident in our Company’s future and the strength of our earnings and cash flow, we plan to continue our capital allocation strategy, while committing to maintain an investment-grade balance sheet and achieving additional investment-grade credit ratings.
“In fourth quarter 2023, we executed a ‘value accelerator initiative’ designed to halt the decline in our electrochemical unit (“ECU”) values and accelerate a favorable inflection point for our Chlor Alkali Products and Vinyls business. We are seeing success with our ‘value accelerator initiative’ but expect to continue to limit our market participation through February 2024, as we remain disciplined in our approach to ECU values. We anticipate our initiative supports an improved 2024 adjusted EBITDA as compared to 2023. Considering the

ongoing difficult global economic environment and our ‘value accelerator initiative,’ we expect first quarter 2024 results from our Chemical businesses to be slightly higher than fourth quarter 2023 levels. We also expect our Winchester business first quarter 2024 results to increase sequentially from fourth quarter 2023. Overall, we expect Olin’s first quarter 2024 adjusted EBITDA to improve by approximately 10% from fourth quarter 2023 levels.”
SEGMENT REPORTING
Olin defines segment earnings as income (loss) before interest expense, interest income, other operating income (expense), non-operating pension income, other income, and income taxes.
CHLOR ALKALI PRODUCTS AND VINYLS
In first quarter 2023, the Blue Water Alliance joint venture began operations and is consolidated in our Chlor Alkali Products and Vinyls segment. Chlor Alkali Products and Vinyls sales for the fourth quarter 2023 were $906.1 million, compared to $1,172.8 million in the fourth quarter 2022. The decrease in Chlor Alkali Products and Vinyls sales was primarily due to lower pricing and a less favorable product mix. Fourth quarter 2023 segment earnings were $65.9 million, compared to $252.3 million in the fourth quarter 2022. The $186.4 million decrease in segment earnings was primarily due to lower volumes and lower pricing, primarily caustic soda, partially offset by lower raw material and operating costs. The Chlor Alkali Products and Vinyls fourth quarter 2023 segment results were negatively impacted by approximately $100 million from the ‘value accelerator initiative.’ Chlor Alkali Products and Vinyls fourth quarter 2023 results included depreciation and amortization expense of $105.4 million compared to $117.6 million in the fourth quarter 2022.
EPOXY
Epoxy sales for the fourth quarter 2023 were $313.1 million, compared to $484.2 million in the fourth quarter 2022. The decrease in Epoxy sales was primarily due to lower product pricing and $94.0 million of lower cumene and bisphenol A sales. As part of the Epoxy business restructuring actions to right-size our global asset footprint to the most cost-effective asset base to support our strategic operating model, the Epoxy business ceased operations at our cumene facility in Terneuzen, Netherlands in first quarter 2023 and one of our bisphenol A production lines at our Stade, Germany facility in fourth quarter 2022. Fourth quarter 2023 segment loss was ($23.1) million, compared to segment earnings of $30.5 million in the fourth quarter 2022. The $53.6 million decrease in Epoxy segment earnings was primarily due to lower pricing and incremental costs associated with inventory reduction, partially offset by lower raw material and operating costs, mainly decreased natural gas and electrical power costs, and an improved product mix. Epoxy fourth quarter 2023 results included depreciation and amortization expense of $13.0 million compared to $22.4 million in the fourth quarter 2022.
WINCHESTER

In fourth quarter 2023, we completed the acquisition of the White Flyer business, which was included in our Winchester segment. White Flyer designs, manufactures and sells recreational trap, skeet, international and sporting clay targets. Winchester sales for the fourth quarter 2023 were $395.4 million, compared to $320.0 million in the fourth quarter 2022. The increase in Winchester sales was primarily due to higher commercial ammunition shipments, higher domestic and international military sales, and White Flyer sales. Fourth quarter 2023 segment earnings were $65.4 million, compared to $45.7 million in the fourth quarter 2022. The $19.7 million increase in segment earnings was primarily due to higher commercial ammunition shipments, higher military sales, and lower operating costs, partially offset by lower commercial ammunition pricing. Winchester fourth quarter 2023 results included depreciation and amortization expense of $8.1 million compared to $6.4 million in the fourth quarter 2022.
CORPORATE AND OTHER COSTS
Other corporate and unallocated costs in fourth quarter of 2023 decreased $12.0 million compared to fourth quarter 2022 primarily due to lower stock-based compensation, including mark-to-market adjustments, a favorable foreign currency impact, and lower legal-related costs.
LIQUIDITY AND SHARE REPURCHASES
The cash balance on December 31, 2023, was $170.3 million and Olin ended the year with net debt of approximately $2.5 billion and a net debt to adjusted EBITDA ratio of 1.9 times. On December 31, 2023, Olin had approximately $1.3 billion of available liquidity.
During fourth quarter 2023, approximately 2.5 million shares of common stock were repurchased at a cost of $116.2 million. During 2023, approximately 13.3 million shares of common stock were repurchased at a cost of $711.3 million. On December 31, 2023, Olin had approximately $1.0 billion available under its current share repurchase authorization.

Olin Corporation
Non-GAAP Financial Measures - Adjusted EBITDA(a)
Olin's definition of Adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) is net income (loss) plus an add-back for depreciation and amortization, interest expense (income), income tax provision (benefit), other expense (income), restructuring (income) charges and certain other non-recurring items. Adjusted EBITDA is a non-GAAP financial measure. Management believes that this measure is meaningful to investors as a supplemental financial measure to assess the financial performance without regard to financing methods, capital structures, taxes or historical cost basis. The use of non-GAAP financial measures is not intended to replace any measures of performance determined in accordance with GAAP and Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies. Reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures are omitted from this release because Olin is unable to provide such reconciliations without the use of unreasonable efforts. This inability results from the inherent difficulty in forecasting generally and quantifying certain projected amounts that are necessary for such reconciliations. In particular, sufficient information is not available to calculate certain adjustments required for such reconciliations, including interest expense (income), income tax provision (benefit), other expense (income) and restructuring (income) charges. Because of our inability to calculate such adjustments, forward-looking net income guidance is also omitted from this release.

Olin Corporation
Non-GAAP Financial Measures - Net Debt to Adjusted EBITDA(a)
Olin's definition of Net Debt to Adjusted EBITDA is Net Debt divided by Adjusted EBITDA. Net Debt at the end of any reporting period is defined as the sum of our current installments of long-term debt and long-term debt, less cash and cash equivalents. Adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) is net income (loss) plus an add-back for depreciation and amortization, interest expense (income), income tax provision (benefit), other expense (income), restructuring (income) charges and certain other non-recurring items. Net Debt to Adjusted EBITDA is a non-GAAP financial measure. Management believes that this measure is meaningful to investors as a measure of our ability to manage our indebtedness. The use of non-GAAP financial measures is not intended to replace any measures of indebtedness or liquidity determined in accordance with GAAP and Net Debt or Net Debt to Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies.
