                CAMBREX CORPORATION ANNOUNCES DELAY IN FILING ITS
                          2005 FORM 10-K ANNUAL REPORT

      East Rutherford, NJ -- March 31, 2006 -- Cambrex Corporation (NYSE: CBM)
announced today that it is unable to complete and file the Company's Annual
Report on Form 10-K for the fiscal year ended December 31, 2005 by the extended
due date of March 31, 2006.

      During the 2005 year-end closing procedures, it was determined that the
Company had incorrectly accounted for U.S. tax benefits related to certain
components of Other Comprehensive Income during 2003, 2004 and 2005. The
cumulative effect of this matter was an understatement of Net Income of
approximately $2.3 million. The Company also determined that certain of its tax
balance sheet accounts had not been properly reconciled and has been working
diligently to complete the appropriate analysis.

      Additionally, the Company is assessing whether it was appropriate to apply
certain technical guidelines that govern the determination of quarterly Income
Tax Expense in 2004 and 2005. The outcome of this assessment would not change
the Company's total Income Tax Expense or Net Income for either year but may
impact quarterly results.

      Until the analyses of the tax accounts are complete, it cannot be
determined whether these matters will result in material adjustments to
previously reported financial statements. The assessment of internal controls
over financial reporting has not been completed. However, based upon the
assessment to date, the Company expects to report a material weakness related to
the Company's internal controls within its corporate tax department.

      The Company expects to file its 2005 Form 10-K with the Securities and
Exchange Commission as soon as it completes the above referenced work. Due to
the foregoing, the Company is postponing its 2006 Annual Meeting of Shareholders
until these matters are resolved.

      The information contained in this press release is unaudited, subject to
revision and should not be considered final until the 2005 Form 10-K is filed
with the U.S. Securities and Exchange Commission.
