On Assignment, Inc. Reports 2003 Third Quarter Results

Calabasas, CA, November 11, 2003 — On Assignment, Inc. (Nasdaq: ASGN) today reported its operating results for the third quarter and nine months ended September 30, 2003.

Highlights of the third quarter: The Company generated operating income of $312,000 and cash from operations of $4,940,000 in the third quarter. Cash, cash equivalents and marketable securities totaled $35,355,000 at quarter end reflecting a sequential net increase of $3,706,000 over the second quarter. Third quarter operating expenses were $13,647,000 compared with $16,068,000 for the year ago quarter, a decrease of 15 percent. Net income per share was $0.01.

Third quarter 2003 revenues were $50,467,000 compared with revenues of $74,583,000 for the third quarter 2002. Lab Support segment revenues for the third quarter were $22,766,000 compared to $28,017,000 in the third quarter last year. Healthcare Staffing segment revenues for the third quarter were $27,701,000 compared to $46,566,000 in the third quarter last year. Operating income for the third quarter 2003 was $312,000 compared with $5,783,000 for the third quarter 2002. Results for the third quarter 2003 include $814,000 in expenses for office closings and facilities consolidation. Net income for the quarter was $235,000 compared with $3,651,000 in the year ago quarter. Net income per share for the third quarter was $0.01 compared with net income per share of $0.14 for the third quarter of 2002.

Dr. Joe Peterson, President and Chief Executive Officer of On Assignment, Inc. said, “During the third quarter, we generated higher positive cash flow from operations primarily resulting from our reductions in operating expenses and improved collections. Our operating income for the third quarter was $312,000 despite incurring $814,000 in charges related primarily to our reduction of real estate commitments. Quarterly operating expenses have been reduced by $2.4 million or 15 percent from the third quarter of 2002. Cash flow from operations was $4,940,000 during the quarter and cash, cash equivalents and marketable securities increased sequentially to $35,355,000 at the end of the quarter from $31,649,000 as of June 30, 2003.”

Continued Dr. Peterson, “We continue to operate in a very difficult environment with no increase in demand. I expect that new demand for our laboratory scientists will not pick up until the economy recovers. Demand for healthcare staff also remains disappointing. We expect it to remain flat until a stabilized economy increases patient census and disrupts the current stability of the nurse workforce, which has also impacted the demand for temporary staffing. That being said, we continue to capture new healthcare clients and expand established hospital relationships with our broadened mix of express and traditional travel nurses. Nurse revenues, nurses on assignment and open orders for nurses increased over the course of the third quarter. Our improved nurse staffing business during the quarter is attributable to our ability to simplify the nurse staffing experience for hospitals, and often to reduce their total cost of flexible staff by improving the mix of types of temporary nurses they deploy. For On Assignment, this strategy of the Company as partner and collaborator with our hospital clients underpins our progress now, and positions us to benefit as demand for nurses increases in the future.”

For the nine months ended September 30, 2003 revenues were $162,471,000 compared with $184,294,000 for the comparable 2002 period. Lab Support segment revenues for the nine-month period ended September 2003 were $71,413,000 compared to $85,892,000 for the same period last year. Healthcare Staffing segment revenues for the nine-month period ended September 2003, including the results of HPO were $91,058,000 compared to $98,402,000 in the same period last year. Nine-month revenues for 2003 include $71,135,000 from HPO (acquired on April 19, 2002) compared with $63,912,000 for the 2002 period. Net loss for the nine months was $79,781,000, compared with a net income of $10,394,000 in the year ago period. Net loss per share for the nine months was $3.13 compared with net income per share of $0.41 for the comparable 2002 period. Included in the 2003 nine months operating loss are charges of $79,897,000 for goodwill impairment and $1,577,000 for severance and related costs resulting from field and headquarters support staff reductions and branch and support office closures.

Reasons for Presentation of Non-GAAP Financial Measures
The Non-GAAP financial measures presented as Operating Income (Loss) Before Impairment of Goodwill in the accompanying supplementary financial information represent the financial measures used by the Company’s management to evaluate the operating performance of the Company for the nine month period ended September 30, 2003. Operating Income (Loss) Before Impairment of Goodwill may not be comparable to similarly titled measures reported by other companies. Operating Income (Loss) Before Impairment of Goodwill excludes certain charges related to impairment of goodwill recorded in the quarter ended June 30, 2003. This Non-GAAP financial information is provided as additional information for investors and is not in accordance with, or an alternative to, GAAP. However, the Company’s management believes these Non-GAAP measures provide useful information to investors, potential investors, securities analysts and others so each group can evaluate the Company’s current and future prospects in the same manner as management if they so choose. The Company’s management believes its Non-GAAP measure of operating performance better reflects the Company’s operations than it does with operating results as presented under GAAP, which includes or may include, from time to time, such non-cash charges related to acquisitions and impairment losses on long-lived assets. A reconciliation of GAAP results has been provided in the financial statement tables that accompany this press release.
