             CAMBREX ANNOUNCES SECOND QUARTER 2005 FINANCIAL RESULTS


      EAST RUTHERFORD, NJ - July 28, 2005 - Cambrex Corporation (NYSE: CBM)
reported second quarter 2005 financial results for the period ended June 30,
2005. Net income for the second quarter 2005 was $7.1 million, or $0.27 per
diluted share, compared to $6.3 million, or $0.24 per diluted share in the
second quarter 2004. Second quarter 2005 results include a tax benefit of $3.2
million, or $0.12 per diluted share, principally due to a favorable Swedish
court decision.

      Sales increased 6.6% to $116.2 million in the second quarter 2005,
including a 1.9% favorable impact from foreign currency, from $109.0 million in
the second quarter 2004 due to higher sales in all business segments.

BIOPRODUCTS

      The Bioproducts segment includes products and services for research and
therapeutic applications. Bioproducts sales in the second quarter 2005 increased
12.7% to $38.0 million, including a 1.7% favorable impact from foreign currency,
from $33.7 million in the second quarter 2004. This represents the ninth
consecutive quarter of double-digit sales growth reflecting stronger demand and
higher pricing.

      Second quarter 2005 Bioproducts gross margin decreased to 50.9% from 55.3%
in the second quarter 2004 primarily due to higher allowances for doubtful
accounts and higher production costs partially offset by better volumes and
pricing. Foreign currency favorably impacted Bioproducts gross margin by
approximately 0.3 percentage points in the second quarter 2005.

      John R. Leone, Cambrex President and Chief Executive Officer commented on
the continued performance in Bioproducts, "Our new product investments continue
to gain momentum. The new European media facility, recently opened Australian
subsidiary, expansion of our efforts in India and acquisition of a rapid
microbial detection business in 2004 have all contributed to the strong sales of
our research products, media, rapid microbial detection products, and related
bioservices."

BIOPHARMA

      The Biopharma segment consists of the Company's contract biopharmaceutical
process development and manufacturing business. Sales in the second quarter 2005
increased 3.6% to $11.7 million from $11.2 million in the second quarter 2004
due to higher reimbursements for labor and materials partially offset by lower
suite and process development fees.

      Second quarter 2005 Biopharma gross margin decreased to -5.2% from 8.5% in
the second quarter 2004 principally due to the unfavorable mix of higher labor
and materials reimbursements and lower suite and process development fees.
Foreign currency had no impact on Biopharma sales or gross margin.

      "We have continued to make progress generating new customers while the
regulatory process moves forward for three products awaiting approval,"
commented Mr. Leone. "We have added three projects that are in or will be
entering Phase III clinical trials. However, until we benefit from more
commercial scale production, sales growth is expected to be somewhat
unpredictable quarter to quarter."

      For the three Phase III projects, tech transfer and process development
has either commenced or is expected to commence during 2005 and 2006 and cGMP
manufacturing is expected to commence in 2006 and 2007.

      Mr. Leone continued, "It is critical that we reduce costs in the Biopharma
segment and we expect to achieve certain cost savings by leveraging the
synergies and infrastructure of the Biopharma and Bioproducts businesses."

HUMAN HEALTH

      The Human Health segment consists of small molecule active pharmaceutical
ingredients (APIs), advanced intermediates and other products derived from
organic chemistry. Human Health sales in the second quarter 2005 increased 4.0%
to $66.5 million, including a 2.5% favorable impact due to foreign currency,
from $64.0 million in the second quarter 2004. The increased sales reflect
higher volumes of branded and generic APIs and advanced intermediates.

      Second quarter 2005 Human Health gross margin decreased to 32.4% from
35.0% in the second quarter 2004 primarily due to product mix. Foreign currency
favorably impacted gross margin by approximately 0.3 percentage points in the
second quarter 2005.

      "Custom development revenues doubled in the quarter; a very positive
indicator of future growth." commented Mr. Leone. "Our excellent regulatory
record, customer service and ability to solve our customers' complex development
issues have allowed us to expand our portfolio of late-stage projects."

SECOND QUARTER 2005 OPERATING, INTEREST AND TAX EXPENSE

      Second quarter 2005 total operating expenses were essentially flat as a
percentage of sales, increasing to $31.2 million (26.9% of sales) from $29.1
million (26.8% of sales) in the second quarter 2004 due to increased sales and
marketing and R&D expenses. Sales and marketing expenses increased to $8.8
million from $8.0 million principally due to additional resources for
Bioproducts and approximately $0.1 million impact from foreign currency.

      Second quarter 2005 research and development expenses increased to $5.9
million (5.1% of sales) from $4.7 million (4.3% of sales) in the second quarter
2004 primarily due to Bioproducts' new product development expenses and
additional headcount at the Cambrex Center of Technical Excellence and
approximately $0.1 million impact from foreign currency.

      Second quarter 2005 administrative expenses decreased to $15.9 million
from $16.0 million in the second quarter 2004 primarily due to lower legal fees
that were partially offset by approximately $0.3 million impact from foreign
currency.

      Second quarter 2005 net interest expense increased to $2.8 million from
$2.7 million in the second quarter 2004. The average interest rate decreased to
5.4% in the second quarter 2005 from 5.6% in the second quarter 2004.

      The tax rate in the second quarter 2005 decreased to -10.4% compared to
37.8% in the second quarter of 2004 primarily due to a $3.2 million ($0.12 per
diluted share) reduction in tax reserves primarily related to a Swedish tax
matter that was decided favorably during the second quarter 2005.

      Capital expenditures for the second quarter 2005 were $9.0 million and
depreciation was $9.3 million compared to $10.9 million and $9.6 million,
respectively, in the second quarter 2004.

AMERICAN JOBS CREATION ACT OF 2004

      During the second quarter 2005, the Company repatriated approximately $50
million of earnings from its foreign subsidiaries pursuant to the American Jobs
Creation Act of 2004 and recorded the related additional tax expense of $0.2
million. The Company continues to evaluate the further repatriation of foreign
earnings.

CAMBREX DECLARES QUARTERLY DIVIDEND

      The Cambrex Board of Directors declared the Company's regular quarterly
cash dividend on its common stock of $0.03 per share for its shareholders of
record as of August 5, 2005. The dividend is payable on August 19, 2005.

GUIDANCE

      Year-to-date performance is consistent with management expectations. A
disproportionate amount of sales and operating profit had been expected to occur
in the second half of the year, primarily due to the expected timing of
development projects and the expected close of a certain number of new proposals
in the Biopharma segment. Based on the latest information related to the close
rate on our Biopharma sales pipeline, the timing of new projects and the timing
of revenues related to these projects, we are revising our full year 2005 sales
growth guidance to be in the range of 3% to 6% and earnings guidance for
continuing operations to be in the range of $0.85 to $0.95 per fully diluted
share including the Swedish tax matter discussed above.

      Based on current customer delivery schedules and seasonal fluctuations in
Human Health, and the timing of expected new business in Biopharma and product
introductions in Bioproducts, it is currently anticipated that a
disproportionate share of the second half 2005 earnings will occur in the fourth
quarter of the year.

      For the year 2005, capital expenditures, depreciation and amortization for
continuing operations are expected to be approximately $49 million, $39 million,
and $2 million respectively. The Company expects the full year 2005 effective
tax rate to be approximately 28-32%. The full year and quarterly effective tax
rates will continue to be highly sensitive to the geographic mix of income.

      The financial information contained in this press release is unaudited,
subject to revision and should not be considered final until the second quarter
2005 Form 10-Q is filed with the US Securities and Exchange Commission.
