On April 14, 2021, Blue Cube Spinco LLC (“Blue Cube”), a wholly-owned subsidiary of Olin Corporation (“Olin”), delivered a notice of optional redemption to the holders of its outstanding 10.00% Senior Notes due 2025 (the “Notes”) issued under the Indenture dated as of October 5, 2015 (as amended and supplemented, the “Indenture”), between Blue Cube and U.S. Bank National Association, as trustee, pursuant to which Blue Cube will redeem all of the $185,000,000 aggregate principal amount of outstanding Notes. The Notes will be redeemed on May 14, 2021 (the “Redemption Date”) at a redemption price in cash of 105.000% of the principal amount of the Notes. Accrued and unpaid interest to, but excluding, the Redemption Date will be paid on the Notes subject to redemption in accordance with the terms of the Indenture and the Notes.

Forward-Looking Statements

Statements in this Current Report on Form 8-K which are not historical in nature are “forward-looking statements” within the meaning of the federal securities laws, including statements regarding the redemption of the Notes. These statements often include words such as “anticipate,” “intend,” “may,” “expect,” “believe,” “should,” “plan,” “outlook,” “project,” “estimate,” “forecast,” “optimistic,” or similar expressions relate to analyses and other information that are based on management’s beliefs, certain assumptions made by management, forecasts of future results, and current expectations, estimates and projections about the redemption of the Notes. However, it should be understood that these statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions, which are difficult to predict and many of which are beyond our control. Therefore, actual outcomes and results may differ materially from those matters expressed or implied in such forward-looking statements. We undertake no obligation to update publicly any forward-looking statements, whether as a result of future events, new information or otherwise.

The risks, uncertainties and assumptions involved in our forward-looking statements, many of which are discussed in more detail in our filings with the Securities and Exchange Commission, including without limitation the “Risk Factors” section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, include, but are not limited to the following: sensitivity to economic, business and market conditions in the United States and overseas, including economic instability or a downturn in the sectors served by us; declines in average selling prices in the chlor alkali industry and the supply/demand balance for our products, including the impact of excess industry capacity or an imbalance in demand for our chlor alkali products; unsuccessful implementation of our operating model, which prioritizes Electrochemical Unit (ECU) margins over sales volumes; our reliance on a limited number of suppliers for specified feedstock and services and our reliance on third-party transportation; failure to control costs or to achieve targeted cost reductions; higher-than-expected raw material, energy, transportation, and/or logistics costs; the occurrence of unexpected manufacturing interruptions and outages, including those occurring as a result of labor disruptions and production hazards; the failure or an interruption of our information technology systems; our substantial amount of indebtedness and significant debt service obligations; the negative impact from the COVID-19 pandemic and the global response to the pandemic; weak industry conditions affecting our ability to comply with the financial maintenance covenants in our senior secured credit facility; the loss of a substantial customer for either chlorine or caustic soda could cause an imbalance in customer demand for these products; failure to attract, retain and motivate key employees; risks associated with our international sales and operations, including economic, political or regulatory changes; the effects of any declines in global equity markets on asset values and any declines in interest rates or other significant assumptions used to value the liabilities in our pension plan; adverse conditions in the credit and capital markets, limiting or preventing our ability to borrow or raise capital; our long-range plan assumptions not being realized causing a non-cash impairment charge of long-lived assets;

new regulations or public policy changes regarding the transportation of hazardous chemicals and the security of chemical manufacturing facilities; changes in, or failure to comply with, legislation or government regulations or policies, including changes within the international markets in which we operate; unexpected litigation outcomes; costs and other expenditures in excess of those projected for environmental investigation and remediation or other legal proceedings; and various risks associated with our Lake City U.S. Army Ammunition Plant contract, including performance and compliance with governmental contract provisions.

All of our forward-looking statements should be considered in light of these factors. In addition, other risks and uncertainties not presently known to us or that we consider immaterial could affect the accuracy of our forward-looking statements.
