Teradata Announces 2008 Second Quarter Results

• Revenue increased 6 percent from the second quarter of 2007

• Gross margin improved 120 basis points from the second quarter of 2007

• Earnings per share of $0.38 versus $0.27 in second quarter of 2007

• Year-to-date “Cash from Operations” of $228 million versus $195 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 $455 million for the second quarter of 2008, a 6 percent increase from $430 million in the second quarter of 2007. Included in the year-over-year comparison was 5 percentage points of benefit from currency translation.⁽¹⁾

Gross margin in the second quarter was 54.7 percent versus 53.5 percent in the second quarter of 2007. Gross margin improved in both product and services, due to the benefit of currency translation, a favorable mix of transactions and contribution from maintenance services.

Teradata’s 2008 second-quarter net income was $69 million, or $0.38 per share, which compared to $49 million, or $0.27 per share, in the second quarter of 2007. As expected, Teradata’s 2008 second quarter results included $9 million of incremental costs associated with Teradata now operating as an independent, publicly-traded company. Teradata’s 2007 second quarter earnings per share included a $0.04 charge for a tax adjustment. Excluding this item, Teradata’s 2007 second quarter non-GAAP earnings per share was $0.31.⁽³⁾

“Teradata delivered solid results in the second quarter of 2008,” said Mike Koehler, president and chief executive officer of Teradata Corporation. “We achieved good revenue growth in EMEA and in our services business, improved both product and service gross margins, and increased our net income. The strength of our international and services business is helping to offset softness in the U.S. market. We are therefore maintaining our guidance for 2008.

“We remain confident in both our technology and our people, who are the best in the business at helping companies integrate data from throughout their enterprise to enable better, faster decision making to gain competitive advantage.”

Regional Operating Segment Results ⁽²⁾

Teradata reports its results in three regional operating segments.

North America and Latin America (Americas)

Teradata generated $236 million of revenue in its Americas region in the second quarter of 2008, down 6 percent from $251 million in the second quarter of 2007. The revenue decline in the Americas region was largely due to customer deferrals relating to the economic environment in the United States.

Gross margin in the Americas region in the second quarter of 2008 was 58.9 percent, compared to 56.2 percent in the second quarter of 2007. Gross margin in the Americas improved primarily due to favorable product deal mix and improved services gross margin.

Europe, Middle East and Africa (EMEA)

Revenue in Teradata’s EMEA region in the second quarter of 2008 was $128 million, up 33 percent from $96 million generated in the second quarter of 2007. The year-over-year revenue increase was led by strong product revenue growth. Currency translation benefited revenue growth in the EMEA region by 11 percentage points.

Gross margin in the EMEA region in the second quarter of 2008 was 53.9 percent, an increase from 46.9 percent in the second quarter of 2007. Gross margin in the EMEA region improved due to the benefit of currency translation, higher product volume and a greater mix of product revenue as compared to services revenue.

Asia Pacific / Japan (APJ)

Teradata generated $91 million of revenue in its APJ region in the second quarter of 2008, a 10 percent increase from $83 million reported in the second quarter of 2007. The year-over-year revenue comparison in the APJ region benefited by 11 percentage points from currency translation.

Gross margin in the APJ region in the second quarter of 2008 was 50.5 percent, down from the 53.0 percent generated in the second quarter of 2007. The lower margin was influenced by the geographic mix of product sales within the region as compared to the prior year period, as well as the higher mix of service revenue as compared to the second quarter of 2007.

Company Operating Results

Operating Income

Second quarter of 2008 operating income was $92 million, compared to $88 million in the second quarter of 2007. Higher overall revenue volume, the net benefit of currency and a favorable deal mix more than offset lower product revenue in the Americas region and the incremental costs associated with Teradata now operating as an independent, publicly-traded company.

Other Items

Other income in the second quarter of 2008 was $2 million, primarily from interest income earned on Teradata’s cash balance. Teradata was not an independent company in 2007, and therefore did not have interest income in the prior-year period.

The effective tax rate in the second quarter of 2008 results was 27 percent versus 44 percent in the second quarter of 2007. Teradata now expects its full-year effective tax rate for 2008 to be approximately 26 to 27 percent.

Cash Flow

During the second quarter of 2008, Teradata generated $85 million of cash from operations, compared to $93 million in the same period in 2007. Cash from operations was lower in the quarterly year-over-year comparison due to additions to working capital.

Capital expenditures of $25 million were comparable to $27 million in the second quarter of 2007. Teradata generated $60 million of free cash flow (cash from operations less capital expenditures and additions to capitalized software) in the second quarter of 2008, versus $66 million in the same period last year.⁽³⁾

The company repurchased approximately 1.4 million shares for $34 million in the second quarter. Free cash flow generation more than offset the use of cash for share repurchases during the quarter.

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

2008 Outlook

Teradata continues to expect 2008 full-year revenue growth of approximately 5 to 8 percent, and earnings per share in the $1.35 to $1.45 range.

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

Teradata reports its results in accordance with Generally Accepted Accounting Principles in the United States, or GAAP. However, as described in footnotes 2 and 3 below, the company believes that certain non-GAAP measures found in this release are useful for investors.

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

2. The Operating Segment results discussed in this earnings release may exclude certain corporate-related costs consistent with the manner by which management evaluates and makes decisions regarding segment operating performance. This presentation is useful to investors because it allows analysis and comparability of operating trends. Schedule D, included in this earnings release, reconciles Teradata’s segment results to total company results reported under Generally Accepted Accounting Principles in the United States, or GAAP. Teradata’s management looks at the company’s results excluding certain items to assess the financial performance of the company. We believe 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 and projections of financial results. Non-GAAP measures, such as those shown in the following tables, should not be considered as substitutes for or superior to results determined in accordance with GAAP. The following table reconciles certain non-GAAP measures contained in this release.

3. Teradata reports its results in accordance with GAAP. However, as described below, the company believes that certain non-GAAP measures, such as free cash flow and non-GAAP EPS, are useful for investors. Our non-GAAP measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures, 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 under GAAP in the second quarter 2007 to the company’s EPS during the period excluding the impact of an extraordinary tax item. Our management regularly uses supplemental non-GAAP financial measures, such as EPS excluding certain extraordinary 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.

Reconciliation of GAAP to Non-GAAP Measures:

	Q2 2008 Actual		Q2 2007 Actual			FY 2008 Guidance
Diluted Earnings Per Share (GAAP)	$	0.38	$	0.27		$1.35  – 1.45
Tax adjustment – second quarter of 2007				(0.04	)
Adjusted Diluted Earnings Per Share (Non-GAAP)	$	0.38	$	0.31		$1.35 – 1.45

(b) 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. This non-GAAP measure should not be considered a substitute for or superior to cash flows from operating activities under GAAP.
