NON-GAAP MEASURES

To supplement the consolidated financial results prepared in accordance with GAAP, onsemi uses certain non-GAAP measures, which are adjusted from the most directly comparable GAAP measures to exclude items related to the amortization of acquisition-related intangibles, expensing of appraised inventory fair market value step-up, inventory valuation adjustments, in-process research and development expenses, restructuring, asset impairments and other, net, goodwill and intangible asset impairment charges, gains and losses on debt prepayment, non-cash interest expense, actuarial (gains) losses on pension plans and other pension benefits, third party acquisition and divestiture-related costs, tax impact of these items, and certain other non-recurring items, as necessary. Management does not consider the effects of these items in evaluating the core operational activities of onsemi. Management uses these non-GAAP measures internally to make strategic decisions, forecast future results, and evaluate onsemi’s current performance. In addition, the Company believes that most analysts covering onsemi use the non-GAAP measures to evaluate onsemi’s performance. Given management’s and other relevant parties' use of these non-GAAP measures, onsemi believes these measures are important to investors in understanding onsemi’s current and future operating results as seen through the eyes of management. In addition, management believes these non-GAAP measures are useful to investors in enabling them to better assess changes in onsemi's core business across different time periods. These non-GAAP measures are not prepared in accordance with, and should not be considered alternatives or necessarily superior to, GAAP financial data and may be different from non-GAAP measures used by other companies. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-GAAP financial measures, even if they have similar names.

Non-GAAP Revenue

The use of non-GAAP revenue allows management to evaluate, among other things, the revenue from the Company’s core businesses and trends across different reporting periods on a consistent basis, independent of special items. In addition, non-GAAP revenue is an important component of management’s internal performance measurement and incentive and reward process as it is used to assess the current and historical financial results of the business and for strategic decision making, preparing budgets, obtaining targets and forecasting future results. Management presents this non-GAAP financial measure to enable investors and analysts to evaluate the Company's revenue generation performance relative to the direct costs of operations of onsemi's core businesses.

Non-GAAP Gross Profit and Gross Margin

The use of non-GAAP gross profit and gross margin allows management to evaluate, among other things, the gross margin and gross profit of the Company’s core businesses and trends across different reporting periods on a consistent basis, independent of non-cash items including, generally speaking, amortization of acquisition-related intangible assets, expensing of appraised inventory fair market value step-up, impact of business wind-down and non-recurring facility costs. In addition, it is an important component of management’s internal performance measurement and incentive and reward process as it is used to assess the current and historical financial results of the business and for strategic decision making, preparing budgets, obtaining targets, and forecasting future results. Management presents this non-GAAP financial measure to enable investors and analysts to evaluate our operating performance independent of certain non-cash items and the effects of certain variables unrelated to our overall operating performance.

Non-GAAP Operating Income and Operating Margin

The use of non-GAAP operating income and operating margin allows management to evaluate, among other things, the operating margin and operating income of the Company’s core businesses and trends across different reporting periods on a consistent basis, independent of non-cash items including, generally speaking, expensing of appraised inventory fair market value step-up, impact of business wind-down, non-recurring facility costs, amortization and impairments of intangible assets, goodwill and intangible asset impairment charges, third party acquisition and divestiture related costs, restructuring charges and certain other special items as necessary. In addition, it is an important component of management’s internal performance measurement and incentive and reward process as it is used to assess the current and historical financial results of the business and for strategic decision making, preparing budgets, obtaining targets, and forecasting future results. Management presents this non-GAAP financial measure to enable investors and analysts to evaluate our operating performance independent of certain non-cash items and the effects of certain variables unrelated to our overall operating performance.

Non-GAAP Net Income Attributable to onsemi and Non-GAAP Diluted Earnings Per Share

The use of non-GAAP net income attributable to onsemi and non-GAAP diluted earnings per share allows management to evaluate the operating results of onsemi’s core businesses and trends across different reporting periods on a consistent basis, independent of non-cash items including, generally, the amortization and impairments of intangible assets, goodwill and intangible asset impairment charges, expensing of appraised inventory fair market value step-up, impact of business wind down, non-recurring facility costs, restructuring, gains and losses on debt prepayment, non-cash interest expense, actuarial (gains) losses on pension plans and other pension benefits, third party acquisition and divestiture-related costs, discrete tax items and other non-GAAP tax adjustments and certain other special items, as necessary. In addition, these items are important components of management’s internal performance measurement and incentive and reward process, as they are used to assess the current and historical financial results of the business and for strategic decision making, preparing budgets, setting targets, and forecasting future results. Management presents these non-GAAP financial measures to enable investors and analysts to understand the results of operations of onsemi’s core businesses and, to the extent comparable, to compare our results of operations on a more consistent basis against those of other companies in our industry.

Free Cash Flow

The use of free cash flow allows management to evaluate, among other things, the ability of the Company to make interest or principal payments on its debt. Free cash flow is defined as the difference between cash flow from operating activities and capital expenditures disclosed under investing activities in the consolidated statement of cash flows. Free cash flow is not an alternative to cash flow from operating activities as a measure of liquidity. It is an important component of management’s internal performance measurement and incentive and reward process as it is used to assess the current and historical financial results of the business and for strategic decision making, preparing budgets, obtaining targets, and forecasting future results. Management presents this non-GAAP financial measure to enable investors and analysts to evaluate our financial performance independent of the cash capital expenditures.

Non-GAAP Diluted Share Count

The use of non-GAAP diluted share count allows management to evaluate, among other things, the potential dilution due to the outstanding restricted stock units excluding the dilution from the convertible notes that is covered by hedging activity up to a certain threshold. In periods when the quarterly average stock price per share exceeds $52.97 for the 0% Notes and $103.87 for the 0.50% Notes, the non-GAAP diluted share count includes the anti-dilutive impact of the Company’s hedge transactions issued concurrently with the 0% Notes and the 0.50% Notes, respectively. At an average stock price per share between $52.97 and $74.34 for the 0% Notes and $103.87 and $156.78 for the 0.50% Notes, the hedging activity offsets the potentially dilutive effect of the 0% Notes and the 0.50% Notes, respectively. In periods when the quarterly average stock price per share exceeds $74.34 for the 0% Notes and $156.78 for the 0.50% Notes, the dilutive impact of the warrants issued concurrently with such notes are included in the diluted shares outstanding.
