PAREXEL REPORTS THIRD QUARTER FISCAL 2003 FINANCIAL RESULTS

– Revenue grows by 18.1% year-over-year –

- Operating margin improves by 2.2 percentage points year-over-year to 6.3% -

Boston, MA, April 23, 2003 – PAREXEL International Corporation (Nasdaq: PRXL) today announced its financial results for the third quarter and nine months ended March 31, 2003.

For the three months ended March 31, 2003, PAREXEL’s consolidated service revenue grew approximately 18.1% to $132.3 million compared with consolidated service revenue of $112.0 million in the prior year quarter. Operating income was $8.3 million, or 6.3% of consolidated service revenue, versus operating income of $4.6 million, or 4.1% of consolidated service revenue in the comparable quarter of the prior year. Net income for the quarter was $4.4 million or $0.17 per diluted share, compared with net income of $3.7 million, or $0.14 per diluted share, for the quarter ended March 31, 2002.

Service revenue for the third quarter was $81.5 million in Clinical Research Services, $26.3 million in the PAREXEL Consulting Group, $17.9 million in Medical Marketing Services, and $6.6 million in Perceptive Informatics, Inc.

For the nine months ended March 31, 2003, consolidated service revenue was $374.0 million versus consolidated service revenue of $320.7 million in the prior year period, an increase of approximately 16.6%. Operating income for the current nine-month period was $17.0 million compared with $11.3 million in the prior year nine-month period. Net income for the nine months was $7.8 million or $0.30 per diluted share, compared with $9.2 million, or $0.36 per diluted share in the prior year nine-month period. On a proforma basis, operating income for the current nine-month period was $22.9 million, net income was $11.5 million, and earnings per diluted share were $0.45. The proforma results do not include a $5.9 million facilities-related restructuring charge recorded in the second quarter of FY 2003 as a result of changes in prior assumptions regarding certain previously abandoned leased facilities. The Company believes that presenting the preceding proforma information, and the proforma earnings per diluted share information discussed below, gives investors a better indication of the Company’s expectations for earnings going forward. Management uses this proforma information internally to evaluate the Company’s performance and manage its operations because management believes that this proforma information facilitates period-to-period comparisons. A reconciliation of Generally Accepted Accounting Principles (GAAP) results to the proforma results may be found in the attached financial tables.

Mr. Josef H. von Rickenbach, PAREXEL’s Chairman and Chief Executive Officer stated, “This quarter PAREXEL achieved strong year-over-year revenue growth of more than 18%, and improved operating margin by 220 basis points. We believe that the relentless dedication and focus that our employees and management team have had on improving profitability have enabled us to achieve these results.”

The Company reconfirmed the forward-looking guidance regarding revenue and earnings per share estimates that it had issued in a press release on April 8, 2003, as follows. For the fourth quarter of Fiscal 2003, the Company anticipates reporting service revenue in the range of $133 to $136 million and earnings per diluted share of approximately $0.19 to $0.21. Achieving those objectives would result in consolidated service revenue for Fiscal 2003 (ending June 30, 2003), in the range of $505 to $510 million, and earnings per diluted share as defined by GAAP in the range of $0.50 to $0.52, and on a proforma basis in the range of $0.64 to $0.66 (excluding the restructuring charge reported in the second quarter of FY 2003). On a GAAP basis for Calendar 2003, the Company anticipates reporting consolidated service revenue of between $520 and $540 million, and earnings per diluted share of between $0.76 and $0.79.
