Cautionary Note Regarding Forward-Looking Statements This communication relates to a proposed business combination transaction between Synaptics Incorporated (“Synaptics”) and ON Semiconductor Corporation (“onsemi”). This communication includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical facts, included or incorporated in this communication could be deemed forward-looking statements, particularly statements about future financial performance and forward-looking financial guidance. These forward-looking statements are based on Synaptics’ and onsemi’s current expectations, estimates and projections about the expected date of closing of the proposed transaction and the potential benefits thereof, their respective businesses and industries, management’s beliefs and certain assumptions made by Synaptics and onsemi, all of which are subject to change. Some of these forward-looking statements can be identified by the use of forward-looking words such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “estimates,” “projects,” “strategy,” “anticipates,” or “Target,” or the negative of those words; other comparable terminology that convey uncertainty of future events or outcomes; or by discussions of strategy, plans, projections or intentions. These forward-looking statements involve known and unknown risks and uncertainties, which may cause Synaptics’ or onsemi’s actual results and performance to be materially different from those expressed or implied in the forward-looking statements. Factors and risks that may impact future results and performance include, but are not limited to, the following factors: (1) the risk that the conditions to the closing of the transaction are not satisfied, including the risk that required approvals from regulators or the stockholders of Synaptics for the transaction are not obtained; (2) litigation relating to the transaction; (3) uncertainties as to the timing of the consummation of the transaction and the ability of each party to consummate the transaction; (4) risks that the proposed transaction disrupts the current plans and operations of Synaptics or onsemi, including restrictions during the pendency of the transaction that may impact the ability to pursue certain business opportunities or strategic transactions; (5) the ability of Synaptics and onsemi to retain and hire key personnel; (6) competitive responses to the proposed transaction; (7) unexpected costs, charges or expenses resulting from the transaction; (8) potential adverse reactions or changes to business relationships resulting from the announcement or completion of the transaction; (9) the combined companies’ ability to achieve the growth prospects and synergies expected from the transaction, as well as delays, challenges and expenses associated with integrating the combined companies’ existing businesses; (10) uncertainty as to the long-term value of onsemi’s common stock; (11) legislative, regulatory and economic developments; and (12) unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as Synaptics’ and onsemi’s response to any of the aforementioned factors. These risks, as well as other risks associated with the proposed transaction, are more fully discussed in the proxy statement/prospectus that is included in the Registration Statement on Form S-4 that has been filed with the Securities and Exchange Commission (“SEC”) in connection with the proposed transaction. While the list of factors presented here is considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. In addition, actual results are subject to other risks and uncertainties that relate more broadly to Synaptics’ overall business, including those more fully described in Synaptics’ filings with the SEC including its annual report on Form 10-K for the fiscal year ended June 27, 2026, and its quarterly reports filed on Form 10-Q for the current fiscal year, and onsemi’s overall business and financial condition, including those more fully described in onsemi’s filings with the SEC including its annual report on Form 10-K for the fiscal year ended December 31, 2025, and its quarterly reports filed on Form 10-Q for its current fiscal year. Investing in onsemi’s or Synaptics’ securities involves a high degree of risk and uncertainty, and readers should carefully consider the trends, risks, and uncertainties described in this communication and other SEC filings of onsemi and Synaptics (including those referenced above) before making any investment decision. If any of these trends, risks, or uncertainties actually occurs or continues, the business, financial condition, or operating results of either or both companies could be materially adversely affected, the trading prices of each company’s securities could decline, and investors could lose all or part of their investment. Forward-looking statements are not guarantees of performance, and speak only as of the date made, and neither onsemi, nor Synaptics nor the management of either entity undertakes any obligation to update or revise any forward-looking statements, except as may be required by law. All forward-looking statements attributable to onsemi, Synaptics, or persons acting on behalf of either company are expressly qualified in their entirety by this cautionary statement. This is not an offer or solicitation. For additional information, please reference slides 137 – 138.

Use of Non-GAAP Financial Measures This presentation contains historical non-GAAP financial measures including, among others, free cash flow (FCF) and FCF margin, non-GAAP gross margin and non-GAAP operating margin. This presentation also contains forward looking non-GAAP financial measures, some of which are adjusted for certain special items. 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 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 prepared in accordance with GAAP. 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. In addition, 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. For a reconciliation of historical non-GAAP financial measures to GAAP, please see the Appendix on slide 127.
