INPHI CORPORATION

RECONCILIATION OF GAAP TO NON-GAAP MEASURES

(in thousands of dollars, except share and per share amounts)

To supplement the financial data presented on a GAAP basis, the Company discloses certain non-GAAP financial measures, which exclude stock-based compensation, legal, transition costs and other expenses, purchase price fair value adjustments related to Cortina acquisition and deferred tax asset valuation allowance. These non-GAAP financial measures are not in accordance with GAAP. These results should only be used to evaluate the Company’s results of operations in conjunction with the corresponding GAAP measures. The Company believes that its non-GAAP financial information provides useful information to management and investors regarding financial and business trends relating to its financial condition and results of operations because it excludes charges or benefits that management considers to be outside of the Company’s core operating results. The Company believes that the non-GAAP measures of gross margin, net income and earnings per share in combination with the Company’s financial results calculated in accordance with GAAP, provide investors with additional perspective and a more meaningful understanding of the Company’s ongoing operating performance. In addition, the Company’s management uses these non-GAAP measures to review and assess the financial performance of the Company, to determine executive officer incentive compensation and to plan and forecast performance in future periods. The Company’s non-GAAP measurements are not prepared in accordance with GAAP, and are not an alternative to GAAP financial information, and may be calculated differently than non-GAAP financial information disclosed by other companies.
