ARMONK, N.Y., April 19, 2010 . . . IBM (NYSE: IBM) today announced first-quarter 2010 diluted earnings of $1.97 per share compared with diluted earnings of $1.70 per share in the first quarter of 2009, an increase of 16 percent.

First-quarter net income was $2.6 billion compared with $2.3 billion in the first quarter of 2009, an increase of 13 percent.  Total revenues for the first quarter of 2010 of $22.9 billion increased 5 percent (flat, adjusting for currency) from the first quarter of 2009.

“In the first quarter, we drove significantly improved revenue growth rates from the fourth quarter across our businesses and geographies.  We had strong results in strategic investment areas including growth markets, business analytics and Smarter Planet solutions,” said Samuel J. Palmisano, IBM chairman, president and chief executive officer.

“Looking ahead, we are confident in our ability to grow revenue, and given our mix of higher-value business and productivity we will expand margins, grow profit, cash and EPS, and increase returns to shareholders.  Thus, we expect full-year 2010 diluted earnings per share of at least $11.20.”

The company also said it expects constant-currency revenue growth for IBM and for its total services, software and hardware businesses in the second quarter.

From a geographic perspective, the Americas’ first-quarter revenues were $9.5 billion, an increase of 2 percent (flat, adjusting for currency) from the 2009 period.  Revenues from Europe/Middle East/Africa were $7.6 billion, up 5 percent (down 2 percent, adjusting for currency).  Asia-Pacific revenues increased 10 percent (1 percent, adjusting for currency) to $5.3 billion.  OEM revenues were $543 million, up 18 percent compared with the 2009 first quarter.  Revenues from the company’s growth markets organization increased 20 percent (8 percent, adjusting for currency) and represented 19 percent of geographic revenues.

Total Global Services revenues increased 4 percent (down 2 percent, adjusting for currency).  Global Technology Services segment revenues increased 6 percent (flat, adjusting for currency) to $9.3 billion.  Global Business Services segment revenues were flat (down 5 percent, adjusting for currency) at $4.4 billion.

IBM signed services contracts totaling $12.3 billion, at actual rates, a decrease of 2 percent (7 percent, adjusting for currency), including 13 contracts greater than $100 million.

Application Management signings decreased 23 percent, or approximately $700 million.  Without the impact of this decline, total services signings would have been up 4 percent year to year.

Signings in Transactional services (Consulting, Integrated Technology Services and Application Management Systems Integration) were $5.5 billion, a decrease of

1 percent (6 percent, adjusting for currency).  Total Outsourcing services (Strategic Outsourcing and Application Management Outsourcing) signings decreased 3 percent (8 percent, adjusting for currency) to $6.8 billion.

Consulting services signings were up 18 percent, with 25 percent of signings related to Smarter Planet and Business Analytics.  Strategic Outsourcing signings increased 6 percent.

The estimated services backlog at March 31 was $134 billion at actual rates compared with $126 billion in the first-quarter 2009.

Revenues from the Software segment were $5.0 billion, an increase of 11 percent (5 percent, adjusting for currency) compared with the first quarter of 2009.  Revenues from IBM’s key middleware products, which include WebSphere, Information Management, Tivoli, Lotus and Rational products, were $2.8 billion, an increase of 13 percent (8 percent, adjusting for currency) versus the first quarter of 2009.  Operating systems revenues of $499 million increased 1 percent (down 3 percent, adjusting for currency) compared with the prior-year quarter.

Revenues from the WebSphere family of software products, which delivers capabilities that enable clients to integrate and manage business processes across the organization, increased 13 percent year over year.  Revenues from Information Management software, which enables clients to integrate, manage and use information to gain business value, increased 11 percent.  Revenues from Tivoli software, which helps clients manage technology and business assets by providing visibility, control and automation across the organization, increased 23 percent, and revenues from Lotus software, which connects people and processes for more effective communication and increased productivity through collaboration, messaging and social networking software, increased 1 percent.  Revenues from Rational software, which supports software development for both IT and embedded system solutions, increased 7 percent.

Revenues from the Systems and Technology segment totaled $3.4 billion for the quarter, up 5 percent (2 percent, adjusting for currency) from the first quarter of 2009.  Systems revenues increased 4 percent (1 percent, adjusting for currency).  Revenues from the System x increased 36 percent.  Revenues from POWER Systems decreased 17 percent compared with the 2009 period.  Revenues from System z mainframe server products decreased 17 percent compared with the year-ago period.  Total delivery of System z computing power, as measured in MIPS (millions of instructions per second), decreased 19 percent.  Revenues from System Storage increased 11 percent, and revenues from Retail Store Solutions increased 38 percent.  Revenues from Microelectronics OEM increased 16 percent.

Global Financing segment revenues decreased 7 percent (12 percent, adjusting for currency) in the first quarter to $537 million.

The company’s total gross profit margin was 43.6 percent in the 2010 first quarter compared with 43.4 percent in the 2009 first-quarter period, led by improving margins in both services segments and software.

Total expense and other income increased 2 percent to $6.5 billion compared with the prior-year period.  In each period, the company had gains from the sale of business operations that were largely offset by workforce rebalancing charges.  SG&A expense of $5.7 billion increased 8 percent year over year and included workforce rebalancing charges of approximately $560 million, the majority of which was in Europe and Asia, compared with prior-year expense of $5.3 billion that included $265 million of workforce rebalancing charges.  RD&E expense of $1.5 billion increased 2 percent compared with the year-ago period.  Intellectual property and custom development income decreased to $261 million compared with $268 million a year ago.  Other (income) and expense was income of $545 million including a gain of $591 million from the sale of Product Lifecycle Management operations, compared with prior-year income of $304 million that included $298 million from the sale of certain elements of the company’s logistics process operations.  Interest expense decreased to $82 million compared with $136 million in the prior year.

IBM’s tax rate in the first-quarter 2010 was 26.0 percent compared with 26.5 percent in the first quarter of 2009.

The weighted-average number of diluted common shares outstanding in the first-quarter 2010 was 1.32 billion compared with 1.35 billion shares in the same period of 2009.  As of March 31, 2010, there were 1.28 billion basic common shares outstanding.

Debt, including Global Financing, totaled $26.3 billion, compared with $26.1 billion at year-end 2009.  From a management segment view, Global Financing debt totaled $22.2 billion versus $22.4 billion at year-end 2009, resulting in a debt-to-equity ratio of 7.0 to 1.  Non-global financing debt totaled $4.1 billion, an increase of $357 million since year-end 2009, resulting in a debt-to-capitalization ratio of 17.7 percent from 16.0 percent.

IBM ended the first-quarter 2010 with $14.0 billion of cash on hand and generated free cash flow of $1.4 billion, up approximately $400 million year over year.  The company returned $4.7 billion to shareholders through $0.7 billion in dividends and $4.0 billion of share repurchases.  The balance sheet remains strong, and the company is well positioned to support its full-year objectives.

Supplemental EPS Information – Acquisition-Related Activity The company is including a view of the impact of certain acquisition-related charges on IBM’s earnings results. Management’s view is that this supplemental information provides additional insight into the company’s ongoing operations and enables a more meaningful comparison to other companies in the technology sector who present similar information.

Non-GAAP Supplementary Materials In an effort to provide investors with additional information regarding the company's results as determined by generally accepted accounting principles (GAAP), the company also discusses, in its earnings press release and/or earnings presentation materials, the following Non-GAAP information which management believes provides useful information to investors. Constant Currency Management refers to growth rates at constant currency or adjusting for currency so that the business results can be viewed without the impact of fluctuations in foreign currency exchange rates, thereby facilitating period-to-period comparisons of the company's business performance. Constant currency revenue results are calculated by translating current period revenue in local currency using the prior year's currency conversion rate. This consistent approach is based on the pricing currency for each country which is typically the functional currency. Generally, when the dollar either strengthens or weakens against other currencies, the growth at constant currency rates or adjusting for currency will be higher or lower than growth reported at actual exchange rates. Cash Flow Management includes presentations of both cash flow from operations and free cash flow that exclude the effect of Global Financing Receivables. For a financing business, increasing receivables is the basis for growth. Receivables are viewed as an investment and an income-producing asset. Therefore, management presents financing receivables as an investing activity. Management’s view is that this presentation gives the investor the best perspective of cash available for new investment or for distribution to shareholders.

Non-GAAP Supplementary Materials Debt-to-Capital Ratio Management presents its debt-to-capital ratio excluding the Global Financing business. A financing business is managed on a leveraged basis. The company funds its Global Financing segment using a debt-to-equity ratio target of approximately 7 to 1. Given this significant leverage, the company presents a debt-to-capital ratio which excludes the Global Financing segment debt and equity because the company believes this is more representative of the company’s core business operations. Unique Items Management presents certain segment financial results excluding the effects of the following items: (1) PLM gain in 2010, (2) Geodis gain in 2009 and (3) Workforce Rebalancing in both 2009 and 2010. Given the unique nature of these items, management believes that presenting certain segment financial information without these items is more representative of the segment’s operational performance and provides additional insight into, and clarifies the basis for, historical and/or future performance, which may be more useful for investors.
