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. 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," or "anticipates," or the negative of those words or other comparable terminology that convey uncertainty of future events or outcomes. 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, will be more fully discussed in the proxy statement/prospectus that will be included in the Registration Statement on Form S-4 that will be 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 28, 2025, 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. Forward-looking statements are not guarantees of performance, and speak only as of the date made, and neither Synaptics nor its management undertakes any obligation to update or revise any forward-looking statements. This is not an offer or solicitation. For additional information, please reference slides 15-16.© onsemi 2026 \| 2
