FOR IMMEDIATE RELEASE

OLIN ANNOUNCES FOURTH QUARTER 2005 RESULTS

CLAYTON, MO, January 30, 2006 – Olin Corporation (NYSE: OLN) announced today that sales for the fourth quarter of 2005 were $604.1 million, compared with $487.3 million in the fourth quarter of 2004. Net income in the fourth quarter of 2005 was $32.6 million, or $0.45 per diluted share, compared with net income of $22.8 million, or $0.32 per diluted share, in the fourth quarter of 2004. Fourth quarter 2005 earnings include a pretax recovery from a third party of $30.4 million of environmental costs incurred and expensed in prior periods and the related interest, a favorable $2.5 million pretax adjustment related to asset retirement obligations, and a pretax charge for an accounting change of $10.5 million related to the adoption of Interpretation 47 of FAS 143 (Accounting for Asset Retirement Obligations).

Net income for the full year 2005 was $133.3 million, or $1.86 per diluted share, compared with net income of $54.8 million, or $0.80 per diluted share, in 2004. Sales in 2005 were $2.4 billion compared to $2.0 billion in 2004. Earnings in 2005 include pretax recoveries from third parties of $49.9 million of environmental costs incurred and expensed in prior periods and the related interest, $9.4 million of pretax gains associated with real estate transactions, the $2.5 million favorable adjustment related to asset retirement obligations, $1.2 million of tax recoveries, and a pretax charge for an accounting change of $10.5 million related to Interpretation 47 of FAS 143.

Joseph D. Rupp, Chairman, President, and Chief Executive Officer, said, “Our fourth quarter net income of $0.45 per diluted share exceeded our guidance of $0.25 per diluted share due primarily to the recovery of environmental expenses and related

interest. As expected, volumes in our Chlor Alkali business were negatively impacted by continuing customer issues related to Hurricanes Katrina and Rita, but ECU netbacks improved to $545 compared to $515 in the third quarter of 2005 and $410 in the fourth quarter of 2004.

Our Metals business improved sequentially over the third quarter of 2005 due to improved costs, while our Winchester business continued to be negatively impacted by rising commodity and raw material costs.

As a consequence of the ongoing cost reduction efforts of our Metals business, we have made the decision to close our Waterbury Rolling Mills facility in Waterbury, Connecticut. In conjunction with this action, we will consolidate these production activities into our East Alton, Illinois mill. We are also considering decisions regarding the possible restructuring or closure of additional facilities, in addition to other overhead reductions.

We intend to record a one-time pretax charge for these actions of $25-30 million in 2006, most of which will occur in the first quarter. We expect this charge to be partially offset by one-time inventory gains of approximately $10 million in 2006. We believe these actions will generate annual cost savings in the $9-12 million range and the implementation of these actions will be cash neutral.

Earnings in the first quarter of 2006, excluding charges associated with the cost reduction efforts of our Metals business, are projected to be in the $0.45 per diluted share range. This forecast reflects improved volumes and higher ECU netbacks compared to the fourth quarter of 2005 in the Chlor Alkali business. Metals earnings are projected to be lower than the first quarter of 2005 due to higher costs and lower volumes, while Winchester earnings are expected to be in line with the first quarter of 2005. Pretax expenses associated with pension and the expensing of stock options are projected to increase by $3 and $1 million per quarter, respectively, compared to 2005.”

SEGMENT REPORTING

We define segment results as income (loss) before interest expense, interest income, other income, and income taxes and include the results of non-consolidated affiliates.

CHLOR ALKALI PRODUCTS

Chlor Alkali product sales for the fourth quarter of 2005 were $156.7 million, compared to $130.0 million in the fourth quarter of 2004. The increase reflects a 10% decline in chlorine and caustic volumes, more than offset by a 33% increase in chlorine and caustic prices. Shipment volumes were impacted during the quarter by customer outages caused by Hurricanes Katrina and Rita. Chlor Alkali income during the quarter was $56.3 million compared to $42.0 million in the fourth quarter of 2004. The higher level of income reflects the higher selling prices offset by lower volumes and higher electricity and transportation costs.

METALS

Metals sales for the fourth quarter of 2005 were $366.7 million compared to $278.6 million for the fourth quarter of 2004. This increase in sales is due primarily to higher copper prices in the fourth quarter of 2005 compared to 2004. Shipment volumes in the fourth quarter of 2005 increased 4% from the fourth quarter of 2004. Electronics and coinage volumes in the fourth quarter of 2005 increased 33% and 38%, respectively, compared to the fourth quarter of 2004, while building product volumes declined 5%. Fourth quarter 2005 ammunition shipments increased 11% over fourth quarter 2004, while automotive shipments were in line with fourth quarter 2004 levels.

For the full year 2005, ammunition and coinage shipments increased 15% and 17%, respectively, compared to 2004. Automotive and building product shipments declined 9% and 8%, respectively, compared to 2004, while 2005 electronics shipments were in line with 2004. Metals segment income in the fourth quarter of 2005 declined to $5.0 million from the fourth quarter of 2004 income of $11.1 million. The decline reflects higher energy costs and metal shrinkage costs caused by higher copper prices. These cost increases more than offset the impact of higher shipments.

WINCHESTER

Winchester fourth quarter 2005 sales were $80.7 million, which is slightly higher than fourth quarter 2004 sales of $78.7 million. Higher levels of domestic military and commercial sales were partially offset by lower international sales. Winchester’s fourth quarter 2005 results were a loss of $0.3 million compared to income of $2.4 million in the fourth quarter of 2004. Higher levels of commodity and other material costs in 2005 more than offset the impact of higher selling prices.

CORPORATE AND OTHER COSTS

For the year 2005, pension expense was $26.2 million, compared to $10.7 million in 2004. The year-over-year increase in pension expense is due primarily to the amortization of pension plan losses from prior periods.

Under Statement of Financial Accounting Standards (“SFAS”) No. 87, the Company recorded non-cash after tax charges of $29.2 million and $23.7 million to Shareholders’ Equity as of December 31, 2005 and December 31, 2004, respectively. These charges reflect an accumulated benefit obligation in excess of the year-end market value of assets of the pension plan. In 2005, the cost impact of plan changes and the adverse effect of lower interest rates more than offset the increase in the value of plan assets. In 2004, the adverse impact of lower interest rates more than offset the increase in plan assets.

The year 2005 results reflect a net environmental credit of $15.8 million which includes recoveries from third parties of costs incurred and expensed in prior periods of $38.5 million. Without these recoveries, charges to income for environmental investigatory and remedial activities would have been $22.7 million, compared with $23.4 million in 2004. These charges relate primarily to remedial and investigatory activities associated with former waste sites and past operations. In 2006, we currently estimate that these charges to income will be in the $20 million range.

During the fourth quarter of 2005 the Company, based on revised estimates of future expenses, reduced the asset retirement obligation it recorded in accordance with the adoption of Financial Accounting Standards No. 143 “Accounting for Asset Retirement

Obligations.” This is reflected as a reduction in corporate and other expenses of $2.5 million. In the fourth quarter of 2004, the Company sold its Indianapolis facility. As a result of this sale, the Company reduced the asset retirement obligation it had previously recorded. This was also reflected as a $2.5 million reduction in corporate and other expenses. Other corporate and unallocated costs increased from 2004 to 2005 due to higher legal and legal-related expenses, a portion of which was related to the environmental recoveries realized in 2005, and higher incentive compensation costs based on higher earnings.

Other operating income for 2005 includes $9.1 million of gains associated with real estate transactions.

In December 2005, the Company adopted Interpretation 47 of Financial Accounting Standards No. 143 “Accounting for Asset Retirement Obligation.” Interpretation 47 clarifies when a company would have sufficient information to estimate the fair value of an asset retirement obligation. In conjunction with this adoption, a pretax non-cash charge of $10.5 million was recorded as an accounting change in the fourth quarter of 2005. This charge is primarily for asset retirement obligations related to production technology and building materials.

INTEREST INCOME

Interest income for 2005 increased by $16.4 million from 2004. The 2005 interest income included interest of $11.4 million associated with the recoveries from third parties of environmental costs incurred and expensed in prior periods. Interest income also increased as a result of higher cash balances and increased short-term investment rates.

DIVIDEND

On January 27, Olin’s Board of Directors declared a dividend of $0.20 on each share of Olin common stock. The dividend is payable on March 10, 2006 to shareholders of record at the close of business February 10, 2006. This is the 317^th consecutive dividend to be paid by the Company.

FORWARD-LOOKING STATEMENTS

This communication includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

The statements contained in this communication that are not statements of historical fact may include forward-looking statements that involve a number of risks and uncertainties.

We have used the words “anticipate,” “intend,” “may,” “expect,” “believe,” “should,” “plan,” “project,” “estimate,” and variations of such words and similar expressions in this communication to identify such forward-looking statements. 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. Relative to the dividend, the payment of cash dividends is subject to the

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

The risks, uncertainties and assumptions involved in our forward-looking statements, many of which are discussed in more detail in our filings with the SEC, including our Annual Report on Form 10-K for the year ended December 31, 2004, 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, such as automotive, electronics, coinage, telecommunications, ammunition, housing, vinyls and pulp and paper;

• extraordinary events, such as terrorist attacks or war with one or more countries;

• economic and industry downturns that result in diminished product demand and excess manufacturing capacity in any of our segments and that, in many cases, result in lower selling prices and profits;

• the cyclical nature of our operating results, particularly 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;

• an increase in our indebtedness or higher-than-expected interest rates, affecting our ability to generate sufficient cash flow for debt service;

• effects of competition, including the migration by United States customers to low-cost foreign locations;

• costs and other expenditures in excess of those projected for environmental investigation and remediation or other legal proceedings;

• unexpected litigation outcomes or the impact of changes in laws and regulations;

• higher-than-expected raw material and energy or 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;

• unexpected additional taxes and related interest as the result of pending income tax audits and unresolved income tax issues; and

• the effects of any declines in global equity markets on asset values and any declines in interest rates used to value the liabilities in our pension plan.

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.
