Teradata Revenue Increases 18 Percent in Constant Currency

ATLANTA – Teradata Corporation (NYSE: TDC) today reported revenue of $665 million for the quarter ended June 30, 2012, an increase of 14 percent from $581 million in the second quarter of 2011. Currency translation reduced the second quarter revenue comparison by 4 percentage points.⁽¹⁾

Gross margin of 57.4 percent was up from the 54.4 percent reported in the second quarter of 2011. On a non-GAAP basis, excluding the special items and stock-based compensation expense described in footnote #2,⁽²⁾ gross margin was 58.5 percent, a 260 basis point improvement from 55.9 percent in the second quarter of 2011. The increase in gross margin was driven by leverage from revenue growth as well as a favorable product and services revenue mix.

Stock-based compensation expense and special items had a $20 million negative impact on Teradata’s second quarter 2012 net income as reported under U.S. Generally Accepted Accounting Principles (GAAP).⁽²⁾

Teradata reported GAAP net income of $112 million, or $0.65 per diluted share, which compared to GAAP net income of $103 million, or $0.60 per diluted share, in the second quarter of 2011. Excluding stock-based compensation expense and the special items detailed in footnote #2,⁽²⁾ non-GAAP net income in the second quarter of 2012 was $132 million, or $0.77 per diluted share, versus $103 million, or $0.60 per diluted share in the second quarter of 2011.⁽²⁾

“Teradata delivered another strong quarter in Q2 with revenue growth of 18 percent in constant currency, and Non-GAAP EPS growth of 28 percent. As a result, we are increasing our guidance for constant currency revenue growth and EPS for 2012,” said Mike Koehler, president and chief executive officer of Teradata Corporation.

“Strong execution across the company led to 20 percent constant currency revenue growth in the first half of 2012 and record operating margin. Our technology leadership and expertise in data warehousing, big data analytics and integrated marketing management uniquely position Teradata to help customers realize the greatest value from their information assets, while enabling them to reduce infrastructure costs.”

Regional Operating Segment Results

Teradata reports its results in three regional operating segments.

Americas

Teradata generated $398 million of revenue in its Americas region, up 17 percent from $339 million in the second quarter of 2011. Currency translation reduced the year-over-year revenue comparison for the Americas region by 1 percentage point.⁽¹⁾

Europe, Middle East and Africa (EMEA)

Revenue in Teradata’s EMEA region was $168 million, up 16 percent from $145 million generated in the second quarter of 2011. Currency translation reduced the year-over-year revenue comparison for the EMEA region by 11 percentage points.⁽¹⁾

Asia Pacific / Japan (APJ)

Teradata generated $99 million of revenue in its APJ region, a 2 percent increase from $97 million in the second quarter of 2011. Currency translation reduced the year-over-year comparison in the APJ region by 2 percentage points.⁽¹⁾

Operating Income

Second-quarter operating income of $160 million increased from $110 million reported in the second quarter of 2011. On a non-GAAP basis, operating income of $188 million increased 31 percent from the second quarter of 2011.⁽²⁾ Higher revenue as well as favorable product and services revenue mix more than offset the increased investment in selling expense and research and development.

Cash Flow

Teradata generated $152 million of cash from operating activities, compared to $179 million in the prior-year period. Teradata generated $113 million of free cash flow (cash from operating activities less capital expenditures and additions to capitalized software)⁽³⁾ in the second quarter of 2012, versus $146 million in the same period in 2011. The decline in cash from operating activities and free cash flow was due to the timing of balance sheet related items between the first and second quarters of the respective years. See the year-to-date information below which normalizes these timing variances.

Year-to-date, Teradata generated $344 million of cash from operating activities, a $59 million increase from $285 million generated in the first half of 2011. Teradata generated $275 million of free cash flow⁽³⁾ in the first half of 2012, a $50 million increase from $225 million generated during the same period in 2011.

Balance Sheet

Teradata ended the second quarter of 2012 with $821 million in cash, a $157 million decrease from March 31, 2012. The net decrease was due in part to acquisition and other investing activities during the quarter. Additionally, Teradata repurchased approximately 545,000 shares for $37 million during the quarter.

As of June 30, 2012, Teradata had total debt of $296 million outstanding under a term loan. Additionally, Teradata has $300 million available through a pre-arranged credit facility; however no funds were drawn from the credit facility.

2012 Outlook

Teradata is raising its expectations for constant currency revenue growth from the 13-15 percent revenue range to the 14-16 percent range. However due to currency changes since early May 2012, when Teradata previously provided revenue guidance, Teradata now anticipates that currency translation will negatively impact the year-over-year revenue comparison by an additional percentage point, based on currency rates on July 30, 2012. As a result Teradata’s expectation for 2012 full-year reported revenue growth remains at 12-14 percent.

Teradata is increasing its guidance for 2012 GAAP earnings per share to the range of $2.34 to $2.44. Excluding stock-based compensation expense and special items, non-GAAP EPS for 2012 is now expected to increase to the range of $2.72 to $2.82, versus prior non-GAAP EPS guidance of $2.60 to $2.70.⁽²⁾
