CIBER ACHIEVES RECORD QUARTERLY REVENUE, GAAP EPS JUMP 100%
2004 On Track for its Highest Annual Revenue and Highest Earnings Since 1999

        GREENWOOD VILLAGE, Colo.—October 26, 2004—CIBER, Inc. (NYSE: CBR), a leading international systems integration consultancy, today reported results for its third quarter ended September 30, 2004, including record revenues and a 100 percent year-over-year GAAP EPS increase.

Overview:

        "The September quarter produced the highest revenue ever for a CIBER quarter and a very solid earnings performance. Consultant headcounts continued to improve in the third quarter, however, utilization was impacted negatively by seasonal U.S. vacations, multiple hurricanes in the southeastern U.S. and European summer holidays. Another favorable year-to-year comparison was the continuation this year of work for the major telecom customer that curtailed spending in the September 2003 quarter. Perhaps most impressive is the operating leverage we are achieving with larger scale. Our EBITA margin was over 7 percent for the quarter, a nearly 40 percent increase compared to 5.1 percent in the third quarter of 2003 when we were 23 percent smaller," said Mac Slingerlend, CIBER's President and Chief Executive Officer.

Business Model Update & Novasoft AG Acquisition:

        "The third quarter showed continued progress with our business model strategies. Our U.S. Custom Commercial group grew by approximately 100 consultants in the third quarter, with Boston, Seattle, Chicago, Orlando and Detroit leading the broad geographic distribution. Our U.S. Federal business was solid and was helped by the new Port of Lake Charles, La. win announced in July and a strong performance by our Remtech subsidiary, which joined us in a business combination in March 2004. Our U.S. State & Local government business continues to be pressured by limited state government finances, but strategic wins in several states kept their results contributing through the summer. Our ERP business (CIBER Enterprise Solutions), despite merger clouds, also posted a steady quarter. Lastly, our now more material European business units were challenged by lack of available hours in the summer due to traditional vacation holidays, however, headcounts and bill rates remained steady and September finished strong, helping them to a good quarter, as well," said Slingerlend.

        "The integration of Novasoft AG acquisition (67 percent owned) in early September is going well. We met most of their employees on a multi-country tour and are very pleased with their quality, dedication and acceptance of the CIBER combination. We hope to be able to acquire most to all of the minority, publicly held positions shortly (the offering circular to purchase these shares has recently been distributed)," Slingerlend continued.

Revenue:

        Revenue for the September 2004 quarter was a record $219.5 million. This represents an increase of 23 percent from the September 2003 quarter and five percent sequentially. The sequential growth included a full quarter of Ascent Technology Ltd.'s operations, compared to a partial quarter at June 2004, plus four weeks of Novasoft AG's revenues, collectively essentially all of the net revenue growth of the quarter. CIBER benefited organically from increased consultant headcounts and billings on a "per available hour basis", however, these were offset by less available hours in the summer quarter. Organic revenue is projected to grow both sequentially and year-over-year in the fourth quarter of 2004.

        For the nine months ended September 2004, record revenue of $607.8 million exceeded 2003's first three quarters' revenue of $524.6 million by 16 percent.

Net Income:

        Net income for the September 2004 quarter of $8.4 million improved 87 percent over the September 2003 quarter of $4.5 million. It was also approximately $500,000 higher than the June 2004 quarter earnings of $7.9 million, despite the facts that the September quarter absorbed seasonal time-off and our annual branding costs associated with a customer-attended national golf tournament.

        For the nine months ended September 2004, net income of $22.3 million represented a 41 percent improvement from the first nine months of 2003 of $15.8 million.

Cash EPS:

        Cash EPS (defined as net income plus tax adjusted amortization of intangible assets) was $0.15 per share for the September 2004 quarter and $0.39 per share for the first three quarters of 2004. These represent 88 percent and 50 percent improvements over like 2003 periods of $0.08 and $0.26 per share, respectively.

GAAP EPS:

        GAAP EPS for the September quarter was $0.14 per share, a 100 percent increase from $0.07 per share for the September 2003 quarter. Nine month GAPP EPS was $0.36 per share, representing an increase of 50 percent over $0.24 per share for the first three quarters of 2003.

Free Cash Flow and Net Free Cash Flow:

        Free Cash Flow (defined as net income + depreciation + amortization - capital expenditures) for the quarter and year-to-date was: ($ Millions, except per share data)

        (Our basic definition of Free Cash Flow does not include all operational working capital changes as we believe the timing of certain payments and receipts unevenly distort quarterly results. We have added "Other Operating Activities Changes" from the Statement of Cash Flows, which may increase or decrease Free Cash Flow, to provide "Net Free Cash Flow".)

•

Domestic Bookings:

        "The September 2004 was a good bookings quarter for our U.S. businesses (approximately $200 million), our third largest bookings ever. Our U.S. pipeline stood at $1.6 billion at quarter's end, up slightly from June 30th. We continue to see greater activity across all of our domestic business model," said Ed Longo, CIBER's Chief Operating Officer.

CIBER's European Operations Focus

        CIBER has significantly increased its European operations in 2004. European revenue for 2003 was $77 million, its expected revenue will be approximately $140 million for 2004, and that Europe will be exiting 2004 with a run rate of approximately $210 million. The increases are principally related to

        "We are very enthused about our dramatic growth in Europe in 2004 and encouraged about 2005. Terje Laugerud, European CEO, and his leadership team are well regarded and working well together. We now have greater critical mass to compete throughout Europe," Slingerlend added.

Strategies & Outlook:

        "In the fourth quarter, we intend to increase our ERP pipeline in the U.S., improve utilization—particularly in Europe, post a solid year-end hardware reselling result and continue our positioning and planning for greater organic growth in 2005."

        "The fourth quarter of 2004 has two less billing days than the third quarter and the most holidays of any calendar quarter. Nonetheless, we believe we can use strong fall utilization and a full quarter of Novasoft's operations to overcome these two issues. We currently believe revenue will be between $230-238 million, Cash EPS will be $0.14-$0.15 per share, and GAAP EPS will be $0.13-$0.14 per share. These would represent quarter-over-quarter increases in revenue of 37-42 percent, Cash EPS increase of 100-115 percent, and GAAP EPS increase of 86-100 percent," Slingerlend concluded.

        Assuming these results are achieved, fiscal 2004 results will be a record $838-846 million in revenue, Cash EPS of $0.53-$0.54, and $0.49-0.50 of GAAP EPS. Comparing 2004 to 2003, these would represent increases of approximately: 21-22 percent in revenue, 56-59 percent in Cash EPS, and 58-61 percent in GAAP EPS.
