ARMONK, N.Y., April 19, 2011 . . . IBM (NYSE: IBM) today announced first-quarter 2011 diluted earnings of $2.31 per share, compared with diluted earnings of $1.97 per share in the first quarter of 2010, an increase of 17 percent.  Operating (non-GAAP) diluted earnings were $2.41 per share, compared with operating diluted earnings of $2.00 per share in the first quarter of 2010, an increase of 21 percent.

First-quarter net income was $2.9 billion compared with $2.6 billion in the first quarter of 2010, an increase of 10 percent.  Operating (non-GAAP) net income was $3.0 billion compared with $2.6 billion in the first quarter of 2010, an increase of 13 percent.

Total revenues for the first quarter of 2011 of $24.6 billion increased 8 percent (5 percent, adjusting for currency) from the first quarter of 2010.

“We delivered a strong first quarter with revenue growth across hardware, software and services and with more than 40 countries growing in double digits.  We continued to see excellent momentum in our growth initiatives - smarter planet, cloud, business analytics, and growth markets - which bring together the full value of the IBM  portfolio,” said Samuel J. Palmisano, IBM chairman, president and chief executive officer.  “We achieved broad-based margin improvement, while our cash flow and strong financial position enabled us to continue to return value to our shareholders.

“On the strength of this performance, we are raising our full-year 2011 operating earnings per share expectations to at least $13.15.”

First-Quarter GAAP — Operating (non-GAAP) Reconciliation

First-quarter operating (non-GAAP) diluted earnings exclude $0.10 per share of charges: $0.09 per share for the amortization of purchased intangible assets and other acquisition-related charges, and $0.01 per share for retirement-related charges driven by changes to plan assets and liabilities primarily related to market performance.

Full-Year 2011 Expectations

IBM raised its expectations for full-year 2011 GAAP diluted earnings per share to at least $12.73 from at least $12.56; and operating (non-GAAP) diluted earnings per share to at least $13.15 from at least $13.00.  The 2011 operating (non-GAAP) earnings

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 earnings presentation materials, the following Non-GAAP information which management believes provides useful information to investors. Operating (Non-GAAP) Earnings Per Share and Related Income Statement Items Management presents certain financial measures excluding the effects of certain acquisition-related charges, non-operating retirement-related costs, and any related tax impacts. Management uses the term "operating" to describe this view of the company's financial results and other financial information. For acquisitions, these measures exclude the amortization of purchased intangible assets and acquisition-related charges such as in-process research and development, transaction costs, applicable restructuring and related expenses, and tax charges related to acquisition integration. For retirement-related costs, the company has characterized certain items as operating and others as non-operating. The company includes service cost, amortization of prior service cost and the cost of defined contribution plans in its operating results. Non-operating retirement-related costs include interest cost, expected return on plan assets, amortized actuarial gains/losses, the impacts of any plan curtailments/settlements, multi-employer plan costs, pension insolvency costs, and other costs. Non-operating costs primarily relate to changes in pension plan assets and liabilities which are tied to market performance, and management considers these costs to be outside the operational performance of the business. Management’s calculation of these operating measures, as presented, may differ from similarly titled measures reported by other companies. Overall, management believes that providing investors with an operating view as described above provides increased transparency and clarity into both the operational results of the business and the performance of the company’s pension plans, improves visibility to management decisions and their impacts on operational performance, enables better comparison to peer companies, and allows the company to provide a long term strategic view of the business going forward. For the 2015 earnings per share roadmap, the company is utilizing an operating view to establish its objectives and track its progress. Effective January 1, 2011, the company’s segment financial results and performance reflect operating earnings, consistent with the company’s management and measurement system. Constant Currency Management refers to growth rates at constant currency or adjusting for currency so that certain financial 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. Financial results adjusted for currency are calculated by translating current period activity in local currency using the comparable prior year period’s currency conversion rate. This approach is used for countries where the functional currency is the local 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. Supplemental Materials

Non-GAAP Supplementary Materials Cash Flow Management uses a free cash flow measure to evaluate the company’s operating results, plan share repurchase levels, evaluate strategic investments and assess the company’s ability and need to incur and service debt. The entire free cash flow amount is not necessarily available for discretionary expenditures. The company defines free cash flow as net cash from operating activities less the change in Global Financing receivables and net capital expenditures, including the investment in software. A key objective of the Global Financing business is to generate strong returns on equity, and increasing receivables is the basis for growth. Accordingly, management considers Global Financing receivables as a profit-generating investment, not as working capital that should be minimized for efficiency. Therefore, management includes presentations of both free cash flow and cash flow from operations that exclude the effect of Global Financing receivables. 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 (PLM Sale and/or Workforce Rebalancing) Management presents certain financial results excluding the effects of the company's PLM sale and/or workforce rebalancing. In March 2010, the company completed the sale of its activities associated with the sales and support of Dassault Systemes’ (Dassault) product lifecycle management (PLM) software, including customer contracts and related assets to Dassault. In addition, the company has taken certain charges in connection with workforce rebalancing actions. Management believes that presenting certain financial information without one or both of these items is more representative of the company’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.
