Teradata Announces 2008 Third Quarter Results

• Gross margin improved 180 basis points from the prior year period

• GAAP Earnings per share of $0.33 versus $0.16 in the third quarter of 2007

• Non-GAAP earnings per share of $0.36 versus $0.29 in the year-ago period^(1a)

• Year-to-date “Cash from Operations” of $322 million versus $289 million in 2007

MIAMISBURG, Ohio – Teradata Corporation (NYSE: TDC), the world’s largest company solely focused on data warehousing and enterprise analytics, today reported revenue of $439 million for the third quarter of 2008, the same as reported in the third quarter of 2007. Included in the year-over-year comparison was 1 percentage point of benefit from currency translation.⁽²⁾

Gross margin in the third quarter was 54.0 percent versus 52.2 percent in the third quarter of 2007. The gross margin improvement was due to a favorable mix of transactions, contribution from maintenance services and the benefit of currency translation. Teradata drove gross margin improvement in both its products and services businesses.

Teradata’s 2008 third-quarter net income was $60 million, or $0.33 per share, which compared to $29 million, or $0.16 per share, in the third quarter of 2007. Included in Teradata’s 2008 third quarter results was a $3 million impairment charge ($0.01 per share) to write down the value of a historical equity investment and a $3 million increase in the income tax provision ($0.02 per share) related to Teradata’s filing of its 2007 federal income tax return in the third quarter of 2008. Excluding these items, non-GAAP earnings per share was $0.36 in the third quarter 2008.^(1a)

Teradata’s results in the third quarter of 2007 included $15 million ($0.07 per share) of costs associated with Teradata’s spin-off from NCR Corporation and a $10 million ($0.06 per share) increase in the income tax provision related to the tax rate change in Germany. Excluding these items, Teradata’s 2007 third quarter non-GAAP earnings per share was $0.29.^(1a)

“We had a good quarter in terms of margins and earnings growth,” said Mike Koehler, president and chief executive officer of Teradata Corporation. “Revenue growth in the third quarter was challenged due to the change in currency exchange rates and the difficult comparison with the strong growth generated in the third quarter of 2007. However, we were encouraged with the growth we saw in our Americas region.

“Teradata is well positioned relative to the market. In today’s economic environment, companies are increasingly looking to integrate and centralize data to reduce costs and get a complete view of their customers, products, risk and financials. This is core to what Teradata provides to its customers.

“However, given the changes in currency exchange rates and business conditions, we are lowering our full-year revenue guidance by 4 percentage points and are reducing our earnings per share expectations accordingly.

“We are continuing to invest to further strengthen our longer term market position while simultaneously managing costs. We’ve increased the number of purpose-built data warehouse platforms we offer and are increasing the number of sales territories to extend our market reach for the years to come.”

Regional Operating Segment Results

Teradata reports its results in three regional operating segments.

North America and Latin America (Americas)

Teradata generated $253 million of revenue in its Americas region in the third quarter of 2008, up 3 percent from $245 million in the third quarter of 2007. The revenue increase in the Americas region was led by growth in Teradata’s maintenance business and higher product revenue.

Gross margin in the Americas region in the third quarter of 2008 was 56.9 percent, up 2.6 points from 54.3 percent in the third quarter of 2007. Gross margin in the Americas improved due to increased contribution from maintenance and product revenue and a favorable deal mix versus the prior year period.

Europe, Middle East and Africa (EMEA)

Revenue in Teradata’s EMEA region in the third quarter of 2008 was $106 million, down 9 percent from $116 million generated in a very strong third quarter of 2007 in which revenue increased 32 percent from the third quarter 2006. Services revenue increased, while product revenue declined. Currency translation benefited the year-over-year revenue comparison in the EMEA region by 2 percentage points.

Gross margin in the EMEA region in the third quarter of 2008 was 51.9 percent, a 100 basis point increase from 50.9 percent in the third quarter of 2007. Gross margin in the EMEA region improved primarily due to deal mix in the quarter and currency.

Asia Pacific / Japan (APJ)

Teradata generated $80 million of revenue in its APJ region in the third quarter of 2008, a 3 percent increase from $78 million reported in the third quarter of 2007. Revenue was up with growth in services more than offsetting declines in product revenue. The year-over-year revenue comparison in the APJ region benefited from 3 percentage points of currency translation.

Gross margin in the APJ region in the third quarter of 2008 was 47.5 percent, a slight increase from the 47.4 percent generated in the third quarter of 2007.

Company Operating Results

Operating Income

Third quarter of 2008 operating income was $86 million, compared to $66 million in the third quarter of 2007. Included in the third quarter of 2008 results was $6 million of recurring incremental costs associated with Teradata operating as an independent publicly-traded company. Included in the third quarter of 2007 operating income was $15 million of costs associated with Teradata’s spin off from NCR Corporation. Excluding the spin-off costs from the third quarter of 2007, the $86 million of operating income in the third quarter of 2008 compared favorably to $81 million in the third quarter of 2007.^(1b)

When comparing operating results excluding the 2007 spin-off costs, a favorable deal mix and the benefit of currency translation more than offset lower product revenue, higher sales and marketing expense and the incremental recurring costs associated with Teradata operating as an independent, publicly-traded company.

Other Items

Interest income of $3 million in the third quarter of 2008 was more than offset by $4 million of other expense, which included a $3 million impairment charge related to the previously discussed equity investment impairment.

The effective tax rate in the third quarter of 2008 results was 29 percent versus 56 percent in the third quarter of 2007. However, the tax rate in the third quarter of 2008 included a $3 million federal income tax accrual adjustment, or approximately 3 percent, related to the filing of the 2007 federal income tax return, while the third quarter of 2007 included a 21 percent tax rate adjustment related to spin-off-related items and Germany’s tax rate change in 2007. Teradata continues to expect its full-year effective tax rate for 2008 to be approximately 26 to 27 percent.

Cash From Operations

During the third quarter of 2008, Teradata generated $94 million of cash from operations, the same as generated in the third quarter of 2007. Capital expenditures of $15 million were lower compared to $23 million in the third quarter of 2007. Teradata generated $79 million of free cash flow (cash from operations less capital expenditures and additions to capitalized software) in the third quarter of 2008, versus $71 million in the same period last year.^(1c)

Balance Sheet

As of September 30, 2008, Teradata had $378 million in cash and short-term investments, an increase of $11 million from June 30, 2008. Free cash flow generation more than offset the use of cash for share repurchases during the quarter. The company repurchased approximately 2.7 million shares for $65 million in the third quarter. Year-to-date, the company repurchased approximately 5.6 million shares for $137 million.

Teradata had no short- or long-term debt outstanding as of Sept 30, 2008.

2008 Outlook

Given the changes in currency exchange rates and the slowing of the global economic environment, Teradata now expects 2008 full-year revenue growth in the 1 to 4 percent range, with GAAP earnings per share expected to be $1.27 to $1.37. Excluding the asset impairment charge and tax adjustment item described above, Teradata expects its 2008 earnings per share, on a non-GAAP basis, to be in the $1.30 to $1.40 range.

Teradata is a trademark or registered trademark of Teradata Corporation in the United States and other countries.

1. Teradata reports its results in accordance with Generally Accepted Accounting Principles in the United States, or GAAP. However, as described below, the company believes that certain non-GAAP measures (such as free cash flow, non-GAAP EPS and non-GAAP operating income, both of which exclude certain items) are useful for investors. Our non-GAAP measures are not meant to be considered in isolation or as substitutes for or superior to results determined in accordance with GAAP, and should be read only in conjunction with our condensed consolidated financial statements prepared in accordance with GAAP.

a) The following table reconciles Teradata’s earnings per diluted share, or EPS, under GAAP in the third quarter of 2008 and 2007, and the company’s 2008 guidance, to the company’s EPS for the periods presented, excluding certain items. Our management regularly uses supplemental non-GAAP financial measures, such as EPS excluding certain items, internally to understand, manage and evaluate our business and make operating decisions. The company believes such non-GAAP financial measures provide useful information to investors regarding the underlying business trends and performance of the company’s ongoing operations and are useful for period-over-period comparisons of such operations and results. The company also believes this information is useful for investors because it can provide consistency and comparability with past reports and projections of future results.

Reconciliation of GAAP to Non-GAAP Measures:

	Q3 2008 Actual		Q3 2007 Actual		FY 2008 Guidance
Diluted Earnings Per Share (GAAP)	$	0.33	$	0.16	$	1.27 – 1.37
Impairment of equity investment		0.01				0.01
Federal income tax accrual adjustment		0.02				0.02
Costs related to Teradata’s spin off from NCR Corporation				0.07
Tax adjustment - tax rate change in Germany				0.06
Adjusted Diluted Earnings Per Share (Non-GAAP)	$	0.36	$	0.29	$	1.30 – 1.40

(b) Teradata’s management also looks at the company’s operating results excluding certain items to assess financial performance. The company believes this information is useful for investors because it can provide a more complete understanding of Teradata’s underlying operational performance, as well as consistency and comparability with past reports. The following table reconciles Teradata’s Operating Income under GAAP in the third quarter of 2008 and 2007 to the company’s results during the period excluding certain items.

Reconciliation of GAAP to Non-GAAP Measures:

(shown in millions)

	Q3 2008 Actual		Q3 2007 Actual
Operating Income (GAAP)	$	86	$	66
Spin-off costs borne by Teradata		—		15
Adjusted Operating Income (Non-GAAP)	$	86	$	81

(c) Teradata defines free cash flow as cash provided/used by operating activities less capital expenditures for property and equipment, and additions to capitalized software. Free cash flow does not have a uniform definition under GAAP and therefore, Teradata’s definition may differ from other companies’ definition of this measure. Teradata’s management uses free cash flow to assess the financial performance of the company and believes it is useful for investors because it relates the operating cash flow of the company to the capital that is spent to continue and improve business operations. In particular, free cash flow indicates the amount of cash generated after capital expenditures for, among other things, investment in the company’s existing businesses, strategic acquisitions, strengthening the company’s balance sheet, repurchase of company stock and repayment of the company’s debt obligations, if any. Free cash flow does not represent the residual cash flow available for discretionary expenditures since there may be other nondiscretionary expenditures that are not deducted from the measure.

2. The impact of currency is determined by calculating the prior period results using the current-year monthly average currency rates.
