onsemi reported Q1 2026 revenue of $1.513 billion, slightly down sequentially but up 5% year-over-year, with non-GAAP operating margin at 19.1%, operating income growing 10% year-over-year—double the pace of revenue growth. The company highlighted more than doubling AI data center revenue and progress in electric vehicle and software-defined vehicle initiatives. Share repurchases totaled $346 million, exceeding free cash flow, reflecting strong capital return focus.

Key Points

  • AI data center revenue more than doubled year-over-year, driven by broader adoption across multiple chip vendors and hyperscalers, signaling robust demand in the AI sector.
  • Continued leadership in 900V EV architectures with EliteSiC technology, supporting extended electric vehicle range and fast charging, with partnerships including Geely and NIO.
  • Strong free cash flow generation enabled significant share repurchases ($346 million), demonstrating capital discipline and commitment to shareholder returns.
  • The semiconductor industry, AI technology sector, automotive (especially EV), and industrial markets are directly impacted by onsemi's performance and advancements.

SECOND QUARTER 2026 OUTLOOK

($6 million)Diluted Earnings Per Share$0.60 to $0.72$0.05
$0.65 to $0.77Diluted Shares Outstanding *401 million7 million394 million


*Diluted shares outstanding can vary as a result of, among other things, the vesting of restricted stock units, the incremental dilutive shares from the convertible notes, and the repurchase or the issuance of stock or convertible notes or the sale of treasury shares. 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 and non-GAAP net income per share include the anti-dilutive impact of the hedge transactions entered 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 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 is included in the diluted shares outstanding. GAAP and non-GAAP diluted share counts are based on either the previous quarter's average stock price or the stock price as of the last day of the previous quarter, whichever is higher.


**Special items may include: amortization of acquisition-related intangibles; expensing of appraised inventory fair market value step-up; restructuring-related cost of revenue charges; non-recurring facility costs; in-process research and development expenses; restructuring, asset impairments and other, net; goodwill impairment charges; gains and losses on debt prepayment; actuarial (gains) losses on pension plans and other pension benefits; and certain other special items, as necessary. These special items are out of our control and could change significantly from period to period. As a result, we are not able to reasonably estimate and separately present the individual impact or probable significance of these special items, and we are similarly unable to provide a reconciliation of the non-GAAP measures. The reconciliation that is unavailable would include a forward-looking income statement, balance sheet and statement of cash flows in accordance with GAAP. For this reason, we use a projected range of the aggregate amount of special items in order to calculate our projected non-GAAP operating expense outlook.


***We believe these non-GAAP measures provide important supplemental information to investors. We use these measures, together with GAAP measures, for internal managerial purposes and as a means to evaluate period-to-period comparisons. However, we do not, and you should not, rely on non-GAAP financial measures alone as measures of our performance. We believe that non-GAAP financial measures reflect an additional way of viewing aspects of our operations that, when taken together with GAAP results and the reconciliations to corresponding GAAP financial measures that we also provide in our releases, provide a more complete understanding of factors and trends affecting our business. 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.

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, restructuring-related cost of revenue charges, 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 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 Gross Profit and Gross Margin

The use of non-GAAP gross profit and gross margin allows management to evaluate, among other things, the gross profit and gross margin of the Company’s core businesses and trends across different reporting periods on a consistent basis, independent of non-cash and non-recurring items including, generally speaking, restructuring-related cost of revenue charges, amortization of intangible assets, amortization 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 income and operating margin of the Company’s core businesses and trends across different reporting periods on a consistent basis, independent of non-cash and non-recurring items including, generally speaking, restructuring-related cost of revenue charges, expensing of appraised inventory fair market value step-up, impact of business wind down, non-recurring facility costs, amortization and impairments of intangible assets, third party acquisition and divestiture-related costs, restructuring charges, asset impairments 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 ON Semiconductor Corporation and Non-GAAP Diluted Earnings Per Share

The use of non-GAAP net income attributable to ON Semiconductor Corporation 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 and non-recurring items including, generally, the restructuring related cost of revenue charges, amortization and impairments of intangible assets, expensing of appraised inventory fair market value step-up, impact of business wind down, non-recurring facility costs, restructuring, asset impairments, gains and losses on debt prepayment, 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 measures 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. For our non-GAAP reporting we apply a projected, normalized non-GAAP effective tax rate of 15% for 2026 and 16% for 2024 and 2025. We calculate this non-GAAP effective tax rate on an annual basis. We may update this non-GAAP effective tax rate at any time for a variety of reasons, including, but not limited to, the rapidly evolving global tax environment, significant changes in our geographic earnings mix or changes to our strategy or business operations. 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 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.


Risks

  • Ongoing restructuring and asset impairment charges present uncertainty that could affect reported GAAP profits and investor perceptions.
  • Potential volatility due to macroeconomic or cyclical semiconductor market factors, as indicated by sequential revenue decline though improving trends are noted.
  • Risks related to achievement and timing of growth in key emerging areas (AI data center, EV, software-defined vehicles) subject to competitive and technological challenges.
