OLIN ANNOUNCES SECOND QUARTER 2021 RESULTS

Second Quarter 2021 Highlights

•Net income of $355.8 million and record adjusted EBITDA of $559.2 million

•ECU Profit Contribution Index improved by 30% compared to first quarter

•Epoxy and Winchester achieved record quarterly segment earnings

Clayton, MO, July 27, 2021 - Olin Corporation (NYSE: OLN) announced financial results for the second quarter ended June 30, 2021.

Second quarter 2021 reported net income was $355.8 million, or $2.17 per diluted share, which compares to second quarter 2020 reported net loss of $120.1 million, or $0.76 per diluted share. Second quarter 2021 adjusted EBITDA of $559.2 million excludes depreciation and amortization expense of $142.0 million and restructuring charges of $14.0 million. Second quarter 2020 adjusted EBITDA was $71.5 million. Sales in the second quarter 2021 were $2,221.3 million compared to $1,241.2 million in the second quarter 2020.

Scott Sutton, Chairman, President and Chief Executive Officer, said, 'Our performance in the second quarter continues to demonstrate the growing success of our unique winning model that prioritizes 'value first.' As predicted, we increased the Electrochemical Unit Profit Contribution Index (ECU PCI). Olin drove sequential pricing improvement in the second quarter 2021 for chlorine, chlorine derivatives, including epoxy resins, and caustic soda. Our Epoxy business continued to improve margins and delivered record quarterly segment results. Our Winchester business also delivered record quarterly segment results. Continuing to build on these successes in second half 2021, Olin now expects to deliver adjusted EBITDA of at least $2.1 billion for 2021. We expect Chlor Alkali Products and Vinyls, Epoxy and Winchester third quarter segment results to increase sequentially. Overall, we also expect third quarter 2021 adjusted EBITDA to improve sequentially from second quarter 2021 levels.'

SEGMENT REPORTING

Olin defines segment earnings as income (loss) before interest expense, interest income, goodwill impairment charges, other operating income (expense), non-operating pension income, other income, and income taxes.

CHLOR ALKALI PRODUCTS AND VINYLS

Chlor Alkali Products and Vinyls sales for the second quarter 2021 were $967.3 million compared to $651.2 million in the second quarter 2020. The increase in Chlor Alkali Products and Vinyls sales was primarily due to higher pricing and volumes. Second quarter 2021 segment earnings were $168.9 million compared to a segment loss of $57.0 million in the second quarter 2020. The $225.9 million increase in segment earnings was primarily due to higher pricing across all products and higher volumes. The segment earnings also reflected higher raw material and operating costs. Chlor Alkali Products and Vinyls second quarter 2021 results included depreciation and amortization expense of $114.5 million compared to $108.5 million in the second quarter 2020.

EPOXY

Epoxy sales for the second quarter 2021 were $850.0 million compared to $397.4 million in the second quarter 2020. The increase in Epoxy sales was primarily due to higher pricing and volumes. The second quarter 2021 segment earnings were $165.3 million compared to a segment loss of $13.0 million in the second quarter 2020. The $178.3 million increase in Epoxy segment earnings was primarily due to higher product margins, as higher pricing was partially offset by higher benzene and propylene raw material costs, and higher volumes. Segment earnings also reflected higher operating costs and maintenance turnaround costs. Epoxy second quarter 2021 results included depreciation and amortization expense of $20.3 million compared to $21.6 million in the second quarter 2020.

WINCHESTER

On October 1, 2020, Winchester began operating the Lake City U.S. Army Ammunition Plant (Lake City). Winchester sales for the second quarter 2021 were $404.0 million compared to $192.6 million in the second quarter 2020. Second quarter 2021 segment earnings were $109.9 million compared to $16.0 million in the second quarter 2020. The increase in second quarter sales and segment earnings was primarily due to higher commercial and military sales, which included ammunition produced at Lake City, and higher commercial ammunition pricing. The segment earnings were also impacted by higher commodity costs. Winchester second quarter 2021 results included depreciation and amortization expense of $5.5 million compared to $4.7 million in the second quarter 2020.

CORPORATE AND OTHER COSTS

Other corporate and unallocated costs in the second quarter of 2021 decreased $6.5 million compared to the second quarter 2020 primarily due to lower costs associated with the absence of implementation of new

enterprise resource planning, manufacturing, and engineering systems, and the related infrastructure costs. This project was completed in late 2020. This reduction was partially offset by higher incentive costs, which includes mark-to-market adjustments on stock-based compensation.

Second quarter 2021 restructuring charges included $10.1 million for employee severance and related benefit costs associated with a productivity initiative to align the organization with the new operating model and improve efficiencies. This organizational alignment initiative is expected to reduce annual costs by approximately $25 million.

CASH AND DEBT REDUCTION

The cash balance on June 30, 2021 was $272.8 million. During the first half 2021, Olin reduced debt by $490.2 million, ending second quarter 2021 with net debt of $3,110.1 million and a net debt to adjusted EBITDA ratio of 2.0 times. Through a combination of improved adjusted EBITDA, disciplined capital spending and debt reduction, Olin expects its net debt to adjusted EBITDA ratio to improve to less than 1.5 times by year end 2021. During 2021, Olin is targeting debt reduction of approximately $1 billion using cash generated from operations.

DIVIDEND

On July 22, 2021, Olin's Board of Directors declared a dividend of $0.20 on each share of Olin common stock. The dividend is payable on September 10, 2021, to shareholders of record at the close of business on August 10, 2021. This will be the 379th consecutive quarterly dividend to be paid by the Company.

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 expense (benefit), other expense (income), restructuring charges, goodwill impairment 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 expense (benefit), other expense (income) and restructuring charges. Because of our inability to calculate such adjustments, forward-looking net income guidance is also omitted from this release. We expect these adjustments to have a potentially significant impact on our future GAAP financial results.

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. Trailing Twelve Months 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 expense (benefit), other expense (income), restructuring charges, goodwill impairment charges and certain other non-recurring items for the previous twelve months. 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.
