Teradata Reports 2013 Second Quarter Results

ATLANTA – Teradata Corporation (NYSE: TDC) today reported revenue of $670 million for the quarter ended June 30, 2013, an increase of 1 percent from $665 million in the second quarter of 2012. Revenue in the second quarter increased 2 percent when compared in constant currency.⁽¹⁾

Gross margin was 56.6 percent, as reported under U.S. Generally Accepted Accounting Principles (GAAP). On a non-GAAP basis, excluding stock-based compensation expense and special items, gross margin was 57.9 percent, which was the second highest non-GAAP gross margin generated for a quarter, second only to the 58.5 percent gross margin in the prior-year period.⁽²⁾

Teradata reported second quarter GAAP net income of $108 million, or $0.65 per diluted share, which compared to GAAP net income of $112 million, or $0.65 per diluted share, in the second quarter of 2012. Stock-based compensation expense and other special items reduced Teradata’s second quarter net income by $18 million (or 11 cents of earnings per diluted share as reported under GAAP).⁽²⁾ Excluding stock-based compensation expense and special items, non-GAAP net income in the second quarter of 2013 was $126 million, or $0.76 per diluted share, versus $132 million, or $0.77 per diluted share, in the second quarter of 2012.⁽²⁾

“We were encouraged with our progress in the second quarter. We had good revenue growth in the U.S., record non-GAAP services gross margin rate, and a non-GAAP operating margin rate which was the second highest quarter ever,” said Mike Koehler, president and chief executive officer, Teradata Corporation.

“Customers are gaining new insights and driving business value from our Unified Data Architecture; which includes Data Warehouses, Aster Analytics, and Hadoop, as well as from our Integrated Marketing solutions. These, along with our latest innovations of adding in-memory to our hybrid virtual storage capabilities, and the release of our expanded Hadoop Portfolio, position us well for the second half of 2013 and beyond.”

Regional Revenue Performance

Operating Income

Second quarter GAAP operating income of $147 million was down from $160 million reported in the second quarter of 2012. On a non-GAAP basis, operating income was $174 million versus $188 million in the second quarter of 2012.⁽²⁾ The difference was primarily due to the strong gross margin performance in the second quarter of 2012, in addition to a less favorable revenue mix and increased investment in sales resources and research and development in the second quarter of 2013.

Cash Flow

During the second quarter of 2013, Teradata generated $140 million of cash from operating activities, compared to $152 million in the prior-year period. Teradata generated $102 million of free cash flow (cash from operating activities less capital expenditures and additions to capitalized software)⁽³⁾ in the second quarter of 2013, versus $113 million in the same period in 2012.

Year to date, Teradata generated $383 million of cash from operating activities, compared to $344 million in the prior-year period. Teradata generated $318 million of free cash flow ⁽³⁾ in the first six months of 2013, versus $275 million in the same period in 2012.

Balance Sheet

Teradata ended the quarter with $826 million in cash, a $27 million decrease from March 31, 2013. The net decrease in cash was mainly due to Teradata using $91 million in the second quarter for share repurchases; 1.6 million shares of its stock were acquired during the second

2

quarter. Year to date, through July 30, Teradata purchased 3.3 million shares for approximately $184 million.

As of June 30, 2013, Teradata had total debt of $281 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.

2013 Outlook

Teradata continues to expect revenue growth for the full-year 2013 to be at the low end of its initial revenue growth rate guidance of 6 to 10 percent, when measured in constant currency⁽¹⁾ and 4 to 5 percent on an as-reported basis. Based on currency rates at the end of July 2013, Teradata now anticipates currency translation to reduce its year-over-year revenue comparison by approximately 1 – 2 percentage points.

Teradata also expects earnings per share for the full-year 2013 to be at the low end of its initial guidance ranges of $2.64-$2.79 on a GAAP basis and $3.05-$3.20 on a non-GAAP basis, which excludes stock-based compensation expense and other special items.⁽²⁾

Special items included in Teradata’s 2013 second quarter GAAP operating income results as reported in this release included $14 million of stock-based compensation expense; $10 million of amortization of acquisition-related intangible assets; and $3 million of acquisition transaction and integration expenses.

Special items for Teradata’s year-to-date non-GAAP net income as reported in this release also included a $4 million income tax expense related to the 2012 U.S. Research & Development tax credit, which was retroactively enacted in the first quarter of 2013. The 2012 R&D tax credit benefit was included in Teradata’s non-GAAP results in the fourth quarter of 2012, since the benefit related the 2012 tax reporting period. However, Teradata did not include the tax benefit in its GAAP results in the fourth quarter of 2012 due to the American Taxpayer Relief Act of 2012 not being enacted until the first quarter of 2013. As a result, the $4 million income tax benefit is included in Teradata’s year-to-date 2013 GAAP net income, but excluded from the company’s year-to-date non-GAAP net income.

The following tables reconcile Teradata’s actual and projected results and EPS, under GAAP to the company’s actual and projected non-GAAP results and EPS for the periods presented, which exclude certain items. Our management regularly uses supplemental non-GAAP financial measures, such as gross margin, operating income, net income and EPS, excluding certain items internally, to understand, manage and evaluate our business and support operating decisions. The company believes such non-GAAP financial measures (1) provide useful information to investors regarding the underlying business trends and performance of the company’s ongoing operations, (2) are useful for period-over-period comparisons of such operations and results, that may be more easily compared to peer companies and allow investors a view of the company’s operating results excluding special items, (3) provide useful information to management and investors regarding present and future business trends, and (4) provide consistency and comparability with past reports and projections of future results.
