GAAP to Non-GAAP Reconciliation
To supplement our consolidated financial statements presented in accordance with generally accepted accounting principles (GAAP), Mellanox uses non-GAAP measures of net income which are adjusted from results based on GAAP to exclude share-based compensation expenses and the changes in certain deferred tax assets. The company believes the non-GAAP results provide useful information to both management and investors, as these non-GAAP results exclude expenses that are not indicative of our core operating results. Management believes it is useful to exclude share-based compensation expenses and the changes in certain deferred tax assets because it enhances investors’ ability to understand our business from the same perspective as management, which believes that such items are not directly attributable to nor reflect the underlying performance of the company’s business operations. Further, management believes certain non-cash charges such as share-based compensation and the changes in certain deferred tax assets do not reflect the cash operating results of the business. These measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results. These non-GAAP measures may be different than the non-GAAP measures used by other companies. A reconciliation of GAAP to non-GAAP condensed consolidated statements of operations is also presented in the financial statements portion of this release and is posted under the “Investors” section at our web site.

Safe Harbor Statement under the Private Securities Litigation Reform Act of 1995:
All statements included or incorporated by reference in this release, other than statements or characterizations of historical fact, are forward-looking statements. These forward-looking statements are based on our current expectations, estimates and projections about our industry and business, management’s beliefs and certain assumptions made by us, all of which are subject to change.

Forward-looking statements can often be identified by words such as “projects,” “anticipates,” “expects,” “intends,” “plans,” “predicts,” “believes,” “seeks,” “estimates,” “may,” “will,” “should,” “would,” “could,” “potential,” “continue,” “ongoing,” similar expressions and variations or negatives of these words. These forward-looking statements are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause our actual results to differ materially and adversely from those expressed in any forward-looking statement.

The risks and uncertainties that could cause our results to differ materially from those expressed or implied by such forward-looking statements include the continued expansion of our product line, customer base and the total available market of our products, the continued growth in demand for our products, the continued, increased demand for industry standards-based technology, our ability to react to trends and challenges in our business and the markets in which we operate, our ability to anticipate market needs or develop new or enhanced products to meet those needs, the adoption rate of our products, our ability to establish and maintain successful relationships with our OEM partners, our ability to effectively compete in our industry, fluctuations in demand, sales cycles and prices for our products and services, our success converting design wins to revenue-generating product shipments, and our ability to protect our intellectual property rights.

In addition, current uncertainty in the global economic environment poses a risk to the overall economy as businesses may defer purchases in response to tighter credit conditions, changing overall demand for our products, and negative financial news. Consequently, our results could differ materially from our prior results due to these general economic and market conditions, political events and other risks and uncertainties described more fully in our documents filed with or furnished to the Securities and Exchange Commission.

Reconciliation of GAAP to Non-GAAP Operating Results
(in thousands, except per share data, unaudited)

* Under GAAP, shares used in computing income per share attributable to ordinary shareholders are adjusted for the amount of time they are outstanding during the period. Shares issued during the period were adjusted for the amount of time they were outstanding during the period as part of the GAAP SHARES – BASIC calculation. The GAAP SHARES – BASIC have been adjusted to a non-GAAP measure as if those ordinary shares were outstanding during the entire period to provide a comparable share number in future quarters.

** This adjustment adds back the GAAP effect of additional ordinary shares that would have been outstanding if the dilutive potential common shares from stock options had been issued under the Treasury method.
