CABOT ANNOUNCES SECOND QUARTER OPERATING RESULTS

• Solid performance in Carbon Black and Metal Oxides arising from strong demand

• Carbon Black continued to experience an unfavorable contract lag due to rising feedstock costs

• Supermetals and Specialty Fluids had a weaker than anticipated quarter

• High feedstock costs unfavorably affected cash and working capital

Cabot Corporation (NYSE:CBT) today announced net income of $11 million ($0.17 per diluted common share) for the second quarter of 2008, including $8 million after-tax ($0.13 per diluted common share) of charges from certain items and a $4 million ($0.06 per diluted common share) charge related to tax reserves. This compares to net income of $30 million ($0.45 per diluted common share) for the second quarter of fiscal 2007, which included $12 million after-tax ($0.17 per diluted common share) of charges from certain items. Cabot’s results during the quarter were unfavorably impacted by approximately $20 million from the time lag of the feedstock related pricing adjustments in the Company’s rubber blacks supply contracts and the immediate recognition of higher feedstock costs in North America, due to the use of LIFO accounting. This compares to a $5 million positive impact from these factors during the same quarter of 2007. The $4 million tax charge resulted from the reversal of tax benefits from China investment credits approved and recorded during the first quarter of 2008 due to changes to Chinese tax regulations issued during the quarter. Details of the Company’s financial results and certain items included in net income are provided in the accompanying tables.

In commenting, Patrick Prevost, Cabot’s President and CEO, said, “Our performance during the quarter did not meet our expectations due to the continued rise of carbon black feedstock costs and weaker than anticipated results in our other businesses. Despite higher

Page 1 of 6

feedstock costs, the Carbon Black Business significantly improved profitability compared to the first quarter of 2008. Both the rubber blacks and performance products product lines were able to expand unit margins. Performance products volumes continued to grow at rates in excess of 5%. Unfortunately the increase in raw material costs, once again, led to a significant unfavorable contract lag effect. We are aggressively managing margins on our non-contracted business and pursuing opportunities to reduce working capital given the environment of rapidly rising feedstock costs. Our inkjet colorants product line improved its volumes significantly over the previous quarter as a result of a recovery in both the OEM and aftermarket segments of the small office home office inkjet market. However, the development in the high speed market segment remains slow.”

Prevost continued, “The Metal Oxides Business continues to perform solidly, although the business was negatively affected by extreme weather conditions in China during the quarter, forcing the shutdown of our manufacturing facility for nearly three weeks. Sales in the silicones portion of this business showed some signs of weakness in Europe and North America. Demand in our electronics and niche segments, however, continues to be strong. The Supermetals Business continues to be impacted by a highly competitive market environment and slower demand in the U.S. We remain focused on generating cash in this business. Our Specialty Fluids Business performed solidly during the second quarter. The business is pursuing multiple opportunities in new geographic regions. More broadly, although the impact of rising carbon black feedstock costs on our working capital is significant, we remain confident in the fundamental strength of the Company and our ability to withstand a volatile environment.”

Business Financial Detail

The following discussion of our results includes information on our reportable segment sales and operating profit before taxes (“PBT”) and should be read in conjunction with the accompanying financial tables. Our Chief Operating Decision Maker uses total segment PBT to measure our consolidated operating results and segment PBT to assess segment performance and allocate resources. Segment PBT includes equity in net income of affiliated companies, royalties paid by equity affiliates, minority interest and allocated corporate costs and excludes interest expense, foreign currency transaction gains and losses, interest income, dividend income, as well as certain

Page 2 of 6

items that have not been allocated to a segment as they are significant and unusual or infrequent. Segment PBT is a non-GAAP financial measure and is not intended to replace income (loss) from continuing operations, the most directly comparable GAAP financial measure. We believe segment PBT assists investors by allowing them to evaluate changes in the operating results of our portfolio of businesses before non-operating factors and before items that are unusual or infrequent that affect net income. Certain items, which are included in net income, are not included in segment PBT. A reconciliation of segment PBT to income (loss) from continuing operations is shown in the accompanying tables.

When explaining the changes in our PBT period on period, we use several terms. The term “fixed costs” means fixed manufacturing costs, including utilities. The term “inventory related changes” means differences attributable to items such as (i) inventory obsolescence and valuation reserves; (ii) utilization variances; and (iii) other increases or decreases in costs associated with the production of inventory. The term “product mix” refers to the various types and grades of products sold by a particular business or product line during the quarter, and the positive or negative impact of that mix on the variable margin and profitability of the business or product line. The term “market segment mix” refers to the various market segments into which a particular business or product line sold its products during the quarter, and the positive or negative impact of that mix on the variable margin and profitability of the business or product line.

Carbon Black Business

The following chart details the percentage change in volume by product line for the second fiscal quarter of 2008, as compared to the second fiscal quarter of 2007 and the first fiscal quarter of 2008:

	Second quarter 2008 vs. second quarter 2007		Second quarter 2008 vs. first quarter 2008
Rubber Blacks	flat volumes		(1	%)
North America	(4	%)	6	%
South America	(10	%)	(16	%)
Europe	(2	%)	8	%
Asia Pacific	9	%	(3	%)
China	2	%	(8	%)
Performance Products	5	%	8	%
Inkjet Colorants	(13	%)	21	%

When comparing the second quarter of 2008 to the second quarter of 2007, rubber blacks volume declines in Europe and South America were driven by decisions we made to change our customer and product mix to maximize profits, with the resulting loss of shorter term volumes. When comparing the second quarter of 2008 to the first quarter of 2008, rubber blacks volume declines in China and Asia Pacific were driven by seasonality due to holidays in those regions.

Revenue Variance Analysis

• The $137 million increase in revenue from the second quarter of 2007 to the second quarter of 2008 was driven by increased selling prices ($78 million), the positive impact of foreign currency translation on our selling prices ($50 million) and increased volumes ($7 million).

• The $70 million increase in revenue from the first to the second quarter of 2008 was driven by increased selling prices ($46 million), the positive impact of foreign currency translation on our selling prices ($18 million) and increased volumes ($5 million).

Page 3 of 6

Profit Variance Analysis

• The $21 million decrease in PBT from the second quarter of 2007 to the second quarter of 2008 was driven by raw material cost increases ($109 million) and higher fixed costs ($6 million). These factors were only partially offset by increased selling prices and favorable product mix ($86 million), the favorable impact of inventory related changes ($3 million), the positive impact of foreign currency translation ($3 million) and higher volumes ($2 million).

• The $15 million increase in PBT from the first to the second quarter of 2008 was driven by higher selling prices and favorable product mix ($47 million), increased volumes ($6 million) and the positive impact of foreign currency translation ($2 million). These positive factors were partially offset by higher raw material costs ($32 million) and higher selling and administrative costs ($7 million).

Variability in feedstock costs significantly impacts financial results for both the Carbon Black Business segment and the Company as a whole on a quarterly basis. The table below quantifies, in millions of dollars, the absolute impact on PBT during a quarter of both the time lag of our feedstock related pricing adjustments in our rubber blacks supply contracts (“contract lag”) and the immediate recognition of feedstock costs in North America due to the use of LIFO accounting (“LIFO impact”).

Metal Oxides Business

Volumes in the fumed metal oxides product line increased by 3% during the second quarter of 2008, when compared to both the second quarter of 2007 and the first quarter of 2008 as increases in the niche and electronics segments more than offset declines in the silicones segment.

Revenue Variance Analysis

• The $5 million increase in revenue from the second quarter of 2007 to the second quarter of 2008 was driven by the positive impact of foreign currency translation on our selling prices ($3 million) and increased volumes ($2 million).

• The $3 million increase in revenue from the first to the second quarter of 2008 was driven by increased volumes ($2 million) and the positive impact of foreign currency translation on our selling prices ($1 million).

Profit Variance Analysis

• The $2 million decrease in PBT from the second quarter of 2007 to the second quarter of 2008 was driven by higher fixed costs ($3 million), principally higher utility costs, higher raw material costs ($1 million) and the unfavorable impact of inventory related changes ($1

Page 4 of 6

million). These factors were only partially offset by increased volumes ($2 million) and a favorable product and market segment mix ($1 million).

• PBT was flat from the first to the second quarter of 2008 as increased volumes ($2 million) and a favorable product and market segment mix ($1 million) were offset by higher raw material costs ($3 million).

Supermetals Business

Revenue Variance Analysis

• The $4 million increase in revenue from the second quarter of 2007 to the second quarter of 2008 was driven by higher volumes ($7 million) principally associated with customer inventory build, and the positive effect of foreign currency translation on our selling prices ($1 million), partially offset by lower selling prices ($4 million).

• The $4 million increase in revenue from the first to the second quarter of 2008 was driven by higher volumes ($6 million) and the positive effect of foreign currency translation on our selling prices ($1 million), partially offset by lower selling prices ($3 million).

Profit Variance Analysis

• PBT was flat from the second quarter of 2007 to the second quarter of 2008 as higher volumes ($2 million) and lower costs ($7 million) were offset by lower selling prices ($4 million), the unfavorable impact of inventory related changes ($4 million) and higher raw material costs ($1 million).

• The $3 million decrease in PBT from the first to the second quarter of 2008 was driven principally by lower selling prices ($3 million), higher raw material costs ($1 million) and higher expenses ($1 million). These unfavorable factors were only partially offset by higher volumes ($3 million).

Specialty Fluids Business

Profit Variance Analysis

• PBT increased by $2 million from the second quarter of 2007 to the second quarter of 2008 as a higher volume of fluid sold from completed jobs more than offset a reduction in our rental volume. This decline in rental volume was due to an unfavorable mix of shorter and smaller jobs.

• PBT decreased by $2 million from the first to the second quarter of 2008 as a reduction in our rental volume, and hence a significantly lower utilization rate, more than offset a higher volume of fluid sold from completed jobs.

The table below quantifies the absolute fluid utilization percentage, which is the percentage of our total available fluid inventory used during a period, by quarter for fiscal 2007 and 2008.

	Fiscal Year 2007		Fiscal Year 2008
Quarter 1	17	%	21	%
Quarter 2	13	%	13	%
Quarter 3	19	%
Quarter 4	12	%

Corporate Financial Detail

Capital Expenditures- Cabot invested approximately $40 million in capital expenditures during the second fiscal quarter of 2008.

Open Market Share Repurchases- During the second fiscal quarter of 2008, the Company repurchased 732,000 shares of its common stock on the open market for a cash cost of approximately $21 million at an average price of approximately $29 per share.

Working Capital- Working capital increased by $27 million on a constant dollar basis (an increase of $74 million at actual exchange rates) during the second fiscal quarter of 2008, driven principally by higher carbon black feedstock costs impacting accounts receivable and inventory values.

Tax Rate- The Company’s overall tax rate for net income from continuing operations was 48% for the second fiscal quarter of 2008. During the quarter, the Company reserved against tax benefits from China investment credits approved and recorded during the first quarter of 2008 due to changes to Chinese tax regulations issued during the quarter. This reserve unfavorably impacted the Company’s operating results by $4 million ($0.06 per diluted common share). Excluding the impact of this reserve, the Company’s tax rate would have been a provision of approximately 27% for the second fiscal quarter of 2008.
