ARCH CHEMICALS REPORTS THIRD QUARTER 2006 EARNINGS IN LINE WITH GUIDANCE; REAFFIRMS FULL YEAR EARNINGS OUTLOOK

Highlights:

· Third quarter earnings from continuing operations were $0.30 per share.

· HTH water products operating income increased $7.9 million over the prior year quarter.

· The Company reaffirms full year earnings guidance to be in the $1.60 to $1.70 per share range.

NORWALK, Conn., October 30, 2006 - ARCH CHEMICALS, INC. (NYSE: ARJ) announced for the third quarter 2006 sales were $354.9 million compared to $314.2 million in the corresponding period in 2005. Segment operating income for the third quarter was $15.2 million in 2006 compared to $15.3 million in 2005. Earnings from continuing operations were $0.30 per share for the third quarter 2006 on $7.3 million of income, compared to $0.28 per share on $6.7 million of income a year ago.

“This quarter’s solid results were driven by the success of our Water Products profit margin improvement plan,” said Arch Chemicals’ Chairman, President and CEO Michael E. Campbell.  “The strong performance of our Water business and continued strong demand for our biocides used in antidandruff shampoos more than offset the impact of unprecedented high raw material costs, which adversely impacted our Wood Protection business in particular.”

The following compares segment sales and operating income (including equity in earnings of affiliated companies) for the third quarters of 2006 and 2005.

Treatment Products

Treatment Products reported sales of $287.7 million and operating income of $17.6 million compared with sales of $252.4 million and operating income of $15.9 million in 2005.

HTH Water Products

HTH water products reported sales of $118.5 million and operating income of $5.9 million in 2006 compared to sales of $95.8 million and an operating loss of $2.0 million in 2005.

Sales increased $22.7 million, or approximately 24 percent, principally due to favorable pricing for both branded and non-branded pool treatment products in the North American market. The increase in volumes due to the acquisition of the remaining 50 percent share of the Company’s Nordesclor water products joint venture ($9.4 million or approximately ten percent) was partially offset by lower volumes due to the shedding of unprofitable business in North America. 

Operating income increased $7.9 million primarily as a result of the improved pricing for the North American product lines. In addition, operating income benefited from favorable product mix and the positive contribution of the acquired business. Lower operating costs were offset in part by severance costs for the European profit improvement plan. 

Personal Care and Industrial Biocides

Personal care and industrial biocides reported sales of $71.8 million and operating income of $10.5 million compared to sales and operating income of $66.9 million and $11.7 million, respectively, in 2005.

Sales increased $4.9 million, or approximately seven percent, due to higher volumes. The higher volumes are attributable to increased demand in the emulsions and in-can preservation markets relative to a soft third quarter in 2005 and continued strong demand for biocides used in antidandruff products. This increase in volumes has been partially offset by lower volumes in the metalworking fluids market due to competitive pressures in certain geographic regions.

Operating income decreased $1.2 million, primarily due to higher raw material costs which offset the higher sales volumes.

2

Wood Protection and Industrial Coatings

Wood protection and industrial coatings reported sales of $97.4 million and operating income of $1.2 million compared to sales and operating income of $89.7 million and $6.2 million, respectively, in 2005.

Sales increased $7.7 million, or approximately nine percent, due primarily to higher volumes. The higher sales volumes are due to increased demand for Tanalith^® E products used in residential applications in Europe and industrial coatings, particularly in the Eastern European market.

Operating income decreased $5.0 million over the prior year primarily in the wood protection business due to higher raw material costs. In addition, the lower operating results in the industrial coatings business were the result of higher raw material costs that were mostly offset by the favorable sales volumes and product mix, as well as higher selling expense due to improved sales volumes and legal costs.  

Performance Products

Performance Products reported sales of $67.2 million and operating income of $4.9 million compared with sales and operating income of $61.8 million and $3.9 million, respectively, in 2005.

Performance urethanes sales increased approximately 6 percent over the prior year due to improved pricing. The improved pricing was principally due to successful price increases that mitigated higher raw material costs. Operating results were comparable to the prior year period as the higher sales were offset by higher raw material costs.

Hydrazine sales increased $2.1 million due primarily to facility fees from the new U.S. government contract. Operating results improved $1.0 million primarily as a result of the increase in sales.

General Corporate Expenses

General corporate unallocated expenses increased by $2.8 million principally due to higher costs associated with the Company's U.K. pension plans.

2006 Outlook

For full year 2006, sales are expected to increase approximately seven to nine percent over 2005 and earnings per share from continuing operations are expected to range from $1.60 to $1.70. Depreciation and amortization is estimated to be approximately $45 million. Capital spending is anticipated to be in the $30 million range. Pension expense is expected to increase by approximately $10 million over the prior year, compared with $7 million from the previous guidance.
