Q&A

Discussion of Non-GAAP Financial Measures Inphi and Marvell believe that the presentation of non-GAAP financial measures provides important supplemental information to management and investors regarding financial and business trends relating to Inphi and Marvell's respective financial condition and results of operations. While Inphi and Marvell use non-GAAP financial measures as a tool to enhance understanding of certain aspects of each company’s financial performance and provide investors with additional perspective and a more meaningful understanding of each company’s ongoing operating performance, Inphi and Marvell do not consider these measures to be a substitute for, or superior to, financial measures calculated in accordance with GAAP. Consistent with this approach, Inphi and Marvell believe that disclosing non-GAAP financial measures to the readers of their financial statements provides such readers with useful supplemental data that, while not a substitute for GAAP financial measures, allows for greater transparency in the review of its financial and operational performance. Inphi and Marvell management believe that investors may find non-GAAP financial measures useful in their assessment of Inphi and Marvell's operating performance, respectively, and the valuation of each company. Non-GAAP financial measures have limitations in that they do not reflect all of the costs associated with the operations of Inphi or Marvell's business as determined in accordance with GAAP. As a result, you should not consider these measures in isolation or as a substitute for analysis of Inphi or Marvell's results as reported under GAAP. The exclusion of the below items from Inphi and Marvell’s GAAP financial metrics does not necessarily mean that these costs are unusual or infrequent. Non-GAAP financial metrics should only be used to evaluate Inphi and Marvell’s results of operations in conjunction with the corresponding GAAP measures. Inphi’s non-GAAP financial measures of non-GAAP operating income and earnings before interest, taxes, depreciation and amortization (“EBITDA”) are shown on an adjusted basis and exclude stock-based compensation, legal, transition costs and other expenses, purchase price fair value adjustments related to acquisitions, non-cash interest expense and loss on extinguishment related to convertible debt, unrealized gain or loss on equity investments, lease expense on building not occupied and deferred tax asset valuation allowance. Marvell’s non-GAAP financial measures of non-GAAP operating income and EBITDA are shown on an adjusted basis and exclude the effect of share-based compensation expense, amortization of the inventory fair value adjustment associated with the Aquantia and Avera acquisitions, amortization of acquired intangible assets, acquisition and divestiture-related costs, restructuring and other related charges (including, but not limited to, asset impairment charges, employee severance costs, and facilities related charges), resolution of legal matters, and certain expenses and benefits that are driven primarily by discrete events that management does not consider to be directly related to Marvell's core business.
