Crompton Reports Second Quarter Results

MIDDLEBURY, Conn.--(BUSINESS WIRE)--July 31, 2003--Crompton
Corporation (NYSE: CK) reported today a second quarter net loss of
$9.1 million, or eight cents per share, compared to a net loss of $6.3
million, or six cents per share, in the second quarter of 2002. As a
result of the previously announced agreement to sell the
OrganoSilicones business to General Electric Company, the accompanying
financial statements reflect the OrganoSilicones business as a
discontinued operation. Second quarter 2003 earnings from discontinued
operations of $10.3 million, or nine cents per share, were equivalent
to the prior year. The loss from continuing operations of $19.4
million, or 17 cents per share, compared to a loss of $16.9 million,
or 15 cents per share, for the second quarter of 2002. The loss from
continuing operations for the second quarter of 2003 included pre-tax
charges of $12.4 million for antitrust legal costs and $2.7 million
for previously announced facility closures, severance and related
costs. The loss from continuing operations for the second quarter of
2002 included pre-tax charges of $34.7 million for the loss on the
sale of the Company's industrial specialties business and $6.4 million
for facility closures, severance and related costs. The second quarter
losses from continuing operations for 2003 and 2002 included pre-tax
overhead expenses previously absorbed by the OrganoSilicones business
of $4.6 million and $3.5 million, respectively.

Second quarter sales from continuing operations of $532.9 million
were seven percent below the prior year due primarily to the
divestiture of the industrial specialties business in June 2002. A
five percent increase in foreign currency translation was offset
primarily by a reduction in unit volume.

"This was a tough quarter for the chemical industry as a whole and
for Crompton in particular," said Vincent A. Calarco, chairman,
president and chief executive officer. "The combined impact of higher
raw material and energy costs, reduced unit volume from a generally
weaker global economic environment and lower selling prices had a
significant negative impact on our earnings. In keeping with our
practice of aggressive cost containment, we are implementing a cost
reduction program to eliminate, at a minimum, overhead expenses
previously absorbed by the OrganoSilicones business.

"Going forward, we will continue to focus on growing sales by
providing innovative products that meet customer needs; maintaining a
cost competitive position; and reducing debt. As external factors
improve, we are operationally leveraged to translate top-line growth
into improved results and improved cash flow from operations."

For the first six months of 2003, the Company reported a net loss
of $3.3 million, or three cents per share, compared to a net loss of
$298.5 million, or $2.63 per share, for 2002. Earnings from
discontinued operations for the first six months of 2003 were $23.3
million, or 20 cents per share, compared to $18.8 million, or 16 cents
per share, in 2002. The loss from continuing operations of $26.1
million, or 23 cents per share, for the first half of 2003 compared to
a loss of $18.3 million, or 16 cents per share, in 2002. The loss from
continuing operations for the first six months of 2003 included
pre-tax charges of $20.9 million for antitrust legal costs and $3.5
million for previously announced facility closures, severance and
related costs. The loss from continuing operations for the first six
months of 2002 included pre-tax charges of $34.7 million for the loss
on the sale of the company's industrial specialties business and $6.4
million for facility closures, severance and related costs. The loss
from continuing operations for the first six months of 2003 and 2002
included pre-tax overhead expenses previously absorbed by the
OrganoSilicones business of $7.2 million and $6.2 million,
respectively. The net loss for the first half of 2003 and 2002
included a cumulative effect of accounting change of $401 thousand and
$299 million, respectively. The Company will incur additional legal
costs in future periods in connection with the governmental
investigations and the related civil litigation, but we expect that
those costs will be lower in each of the third and fourth quarters
than the pre-tax total of $12.4 million incurred in the second
quarter.

Second quarter operating results for the Company's reporting
segments are summarized as follows:

Polymer Products
Polymer additives sales of $294.6 million were up two percent from
the prior year due to favorable foreign currency translation of five
percent, offset in part by a decline in unit volume of two percent and
lower selling prices of one percent. Plastic additives sales increased
five percent due mainly to favorable foreign currency translation.
Urethane and petroleum additives sales rose 11 percent and seven
percent, respectively, due primarily to favorable foreign currency
translation and increased demand. Rubber additives sales declined 15
percent mainly as a result of lower selling prices and reduced unit
volume. Operating profit of $6.9 million was down 72 percent from the
prior year due primarily to higher raw material costs, an unfavorable
sales mix, lower selling prices, an environmental charge of $1.3
million and the absence of a prior year vendor settlement credit of
$1.2 million.

Polymers sales of $70.3 million were down three percent from the
second quarter of 2002 as a result of lower selling prices of five
percent and reduced unit volume of one percent, partially offset by
favorable foreign currency translation of three percent. EPDM sales
declined two percent mainly as a result of the negative impact of
industry overcapacity on selling prices, offset in part by higher unit
volume and favorable foreign currency translation. Urethanes sales
were down four percent due mainly to reduced demand, partially offset
by favorable foreign currency translation. Operating profit of $4.9
million was down 61 percent from the prior year mainly as a result of
lower EPDM selling prices, higher raw material costs and reduced unit
volume in urethanes.

Polymer processing equipment sales of $40.6 million were down nine
percent from the prior year due to reduced demand for capital
equipment, offset in part by five percent improvements in both selling
prices and foreign currency translation. Operating profit of $1.0
million was up $3.7 million from the prior year due primarily to lower
operating expenses and favorable selling prices, partially offset by
lower unit volume. The backlog at the end of June was $75 million,
down $1 million from the end of 2002.

Specialty Products
Crop protection sales of $71.6 million were up one percent from
the prior year due to favorable foreign currency translation of five
percent, offset by a decline in unit volume of four percent. Operating
profit of $14.2 million was down 31 percent from the second quarter of
2002 mainly as a result of lower unit volume, an unfavorable sales mix
resulting from increased sales of resale products and the absence of a
prior year vendor settlement credit of $1.6 million.

Other sales of $59.4 million were down 41 percent from the prior
year due mainly to the divestment of the industrial specialties
business in June 2002. Refined products sales were up two percent as
higher selling prices and favorable foreign currency translation more
than offset lower unit volume. The operating loss of $.6 million was
unfavorable versus the prior year by $2.7 million due primarily to the
divestiture of the industrial specialties business and increased
environmental-related expenses of $2.6 million, partially offset by
higher selling prices.

General corporate expense of $6.2 million included in the attached
Segment Sales and Operating Profit decreased $5.6 million from the
second quarter of 2002 due primarily to the gain on the Company's
equity derivative contract that matured in May, 2003.

Discontinued Operations
Sales included in discontinued operations of $113.3 million were
down four percent from the prior year due to a decline in selling
prices of six percent and lower volume of four percent, offset in part
by favorable foreign currency translation of six percent. Earnings
from discontinued operations of $10.3 million (net of income taxes of
$3.5 million) were 3% lower than the prior year of $10.6 million (net
of income taxes of $2.6 million), mainly as a result of reduced
selling prices and lower unit volume, partially offset by lower
operating expenses and the absence of a prior year pre-tax charge for
facility closures, severance and related costs of $2.9 million.
