TO KIK CUSTOM PRODUCTS FOR $315 MILLION

Commences Exploration of Sale of Agrochemicals Business

Board Seeks To Unlock Inherent Value in Portfolio for Shareholders and
Create Focused Leader in Industrial Specialty Chemicals

Company Provides Update on Third Quarter 2013 Performance

____________________________________

PHILADELPHIA, October 10, 2013 – Chemtura Corporation (NYSE: CHMT) (Euronext: CHMT) (“Chemtura” or the “Company”) today announced that it has entered into a stock purchase agreement to sell its Consumer Products business, including dedicated manufacturing plants in the U.S. and South Africa, to KIK Custom Products Inc. (“KIK”) for $315 million in cash at closing subject to certain customary pre- and post-closing adjustments, including for working capital and assumed pension liabilities. The Company also announced today that its board of directors has decided to explore a sale of the Company’s agrochemicals business, Chemtura AgroSolutions.

The agreement to sell the Consumer Products business, combined with the decision to explore a sale of Chemtura AgroSolutions, is aimed at delivering substantial near-term value to shareholders while further focusing the Company on opportunities to create additional value as a pure-play leader in the global development, marketing, manufacture and sale of industrial specialty chemicals.

The Company expects to use a substantial portion of the proceeds from the sale of Consumer Products and potential sale of the agrochemicals business to return capital to shareholders. The Company will also use proceeds to continue to make important investments to strengthen and enable the continuing growth of the remaining businesses, as well as pay down debt in order to return towards its long-term stated total leverage target of approximately 2X Adjusted EBITDA.

"Today’s announcements represent the next step in our plan to simplify and transform our portfolio, positioning us to better benefit from secular industry growth trends in our chosen areas of market focus and create a sustainable competitive advantage,” said Craig A. Rogerson, Chairman, President and CEO of Chemtura. “Following the sales of our Consumer Products and Antioxidants businesses, a sale of Chemtura AgroSolutions would transform Chemtura into a more focused, pure-play industrial specialty chemicals company with leading global positions that we believe can capitalize on attractive end-market growth trends, and continue delivering superior value to our shareholders and opportunities for our employees for many years to come.”

POTENTIAL SALE OF CHEMTURA AGROSOLUTIONS

Mr. Rogerson continued, “A sale of Chemtura AgroSolutions at the right price would be a compelling opportunity to unlock significant value for our shareholders and a logical strategic step for Chemtura at this time. We recognize the strength of our agrochemicals business and its long-term prospects. However, we believe our current share price does not fully reflect its embedded value. We have received credible unsolicited expressions of interest and the board has determined, consistent with its fiduciary duties, that this is the right time to invite and evaluate offers for the business. Importantly, while we think this may be a compelling financial opportunity, we will complete a sale only if we can realize an attractive value for the business.”

Chemtura AgroSolutions is a leading provider of fungicides, herbicides, insecticides, miticides, plant growth regulators and seed enhancement products for select crops in attractive geographies, with a strong new product portfolio and development program and field service expertise. It is a healthy and profitable business segment which generated revenues of $435 million and Adjusted EBITDA of $89 million in the last twelve months ending June 30, 2013 (refer to reconciliation table). Chemtura AgroSolutions has a global presence serving customers in more than 120 countries.

The Company has retained Morgan Stanley & Co. LLC to act as its financial advisor in connection with the Chemtura AgroSolutions divestiture process. Debevoise & Plimpton LLP is acting as its legal counsel.

The Company notes that a definitive timetable for the sale process has not been finalized and there can be no assurance that the process will result in a sale of the Chemtura AgroSolutions business.

MORE FOCUSED PLATFORM GOING FORWARD

Following a sale of Consumer Products and potential sale of the Company’s agrochemicals business, Chemtura’s core platform will be focused and organized around two attractive segments: Industrial Performance Products (“IPP”) (petroleum additives and urethanes products) and Industrial Engineered Products (“IEP”) (flame retardants and brominated products, and organometallics). These segments have leading global industry positions in a number of markets.

Mr. Rogerson added, “Chemtura is well-positioned to extend IPP and IEP in the faster growing regions and in high opportunity applications across markets that offer strong secular growth. For example, in the fourth quarter, we will formally open our new multipurpose plant in Nantong, China, and we are committed to continuing to invest in these kinds of platforms for higher margin products going forward.

SALE OF CONSUMER PRODUCTS

With regard to the sale of the Consumer Products business, Mr. Rogerson said, “We have already addressed a portion of the stranded costs associated with this segment and have plans in place to rapidly eliminate the remainder after the transaction closes. KIK is a respected manufacturer and employer, and we believe that the Consumer Products business will be in good hands.”

With over $1.2 billion in sales in 2012, and more than 3,000 employees, Toronto, Canada-based KIK is one of North America’s largest contract and private label manufacturers of consumer, institutional and industrial products. The KIK network includes 14 integrated manufacturing facilities strategically located throughout North America. KIK’s product lines include bleach, household cleaners and sanitizers, pool and spa water treatment products and additives, personal care and over-the-counter medicated and pharmaceutical products, all supported by in-house technical expertise and value-added services. KIK produces national brand and private label consumer products for Fortune 500 companies. For more information about KIK, visit www.kikcorp.com.

The Consumer Products business is known as BioLab in North America and Bayrol in Europe. The purchase price is subject to pre- and post-closing adjustments for working capital and assumed pension liabilities. The transaction is subject to customary closing conditions and regulatory approvals with a targeted close date of December 31, 2013.

Chemtura expects to begin accounting for its Consumer Products segment as a “discontinued operation” in its third quarter 2013 financial statements. Before the end of November, Chemtura anticipates making available historical GAAP and Managed Basis statements of income reflecting the discontinued operations treatment to assist investors in making prior period comparisons.

THIRD QUARTER 2013 UPDATE

Mr. Rogerson continued, “While we are excited about the future opportunities for our industrial segments, especially with the new Nantong multipurpose plant officially opening in the fourth quarter, the near-term weakness we have seen in the first half of 2013 for the IEP segment continued in the third quarter. Electronics and insulation foam applications remained weak and we have concluded to record an increase in inventory reserves for some slower moving electronics products. As a result, third quarter operating income for IEP will be close to break-even. This quarter, IPP absorbed the initial start-up costs of its new plants in the Netherlands and China, but still expects to deliver about the same level of operating income as it did in the third quarter of 2012. Chemtura AgroSolutions has continued its strong track record of improvement and looks set to show year-on-year growth in operating income of approximately 15%. These performance trends combined with the impact of adopting discontinued operations treatment for the Consumer Products segment will result in our third quarter earnings being substantially lower than current consensus.”
