    • Total stock-based compensation expenses of $40.2 million to $42.2 million.
    • Beginning with the Q1 2023 outlook, MPS no longer separately forecasts litigation expenses.

    (1) Non-GAAP net income, non-GAAP earnings per share, non-GAAP gross margin, non-GAAP R&D and SG&A expenses, non-GAAP operating expenses, non-GAAP other income, net, non-GAAP operating income and non-GAAP income before taxes differ from net income, earnings per share, gross margin, R&D and SG&A expenses, operating expenses, other income (expense), net, operating income and income before taxes determined in accordance with Generally Accepted Accounting Principles in the United States (“GAAP”). Non-GAAP net income and non-GAAP earnings per share exclude the effect of stock-based compensation expense, deferred compensation plan income/expense, amortization of purchased intangible assets and related tax effects. Non-GAAP gross margin excludes the effect of stock-based compensation expense and deferred compensation plan expense. Non-GAAP operating expenses exclude the effect of stock-based compensation expense, amortization of purchased intangible assets and deferred compensation plan income/expense. Non-GAAP other income, net excludes the effect of deferred compensation plan income/expense. Non-GAAP operating income excludes the effect of stock-based compensation expense, amortization of purchased intangible assets and deferred compensation plan income/expense. Non-GAAP income before taxes excludes the effect of stock-based compensation expense, amortization of purchased intangible assets and deferred compensation plan income/expense. Projected non-GAAP gross margin excludes the effect of stock-based compensation expense. Projected non-GAAP R&D and SG&A expenses exclude the effect of stock-based compensation expense. These non-GAAP financial measures are not prepared in accordance with GAAP and should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. A schedule reconciling non-GAAP financial measures is included at the end of this press release. MPS utilizes both GAAP and non-GAAP financial measures to assess what it believes to be its core operating performance and to evaluate and manage its internal business and assist in making financial operating decisions. MPS believes that the inclusion of non-GAAP financial measures, together with GAAP measures, provides investors with an alternative presentation useful to investors’ understanding of MPS’s core operating results and trends. Additionally, MPS believes that the inclusion of non-GAAP measures, together with GAAP measures, provides investors with an additional dimension of comparability to similar companies. However, investors should be aware that non-GAAP financial measures utilized by other companies are not likely to be comparable in most cases to the non-GAAP financial measures used by MPS.
