Rhea-AI Filing Summary

ON Semiconductor Corporation (onsemi) is buying Synaptics in an all-stock merger valued at approximately $7 billion. Synaptics stockholders will receive 1.350 shares of onsemi common stock for each Synaptics share, an exchange ratio that implies roughly a 19% premium to the companies’ 10‑day volume‑weighted average prices.

After closing, Synaptics equityholders are expected to own about 12% of the combined company, and Synaptics will become a wholly owned onsemi subsidiary and be delisted from Nasdaq. The deal is aimed at combining onsemi’s power and sensing portfolio with Synaptics’ Edge AI compute, human‑machine interface and connectivity solutions, targeting a projected expansion of onsemi’s total addressable market by $30 billion to $243 billion by 2030.

Closing is targeted for mid‑2027 and depends on approval by Synaptics stockholders, antitrust and foreign investment clearances, effectiveness of an S‑4 registration statement, Nasdaq listing of the new onsemi shares, and other customary conditions. The Merger Agreement includes a $235 million termination fee payable by Synaptics in certain circumstances and a $320 million regulatory termination fee payable by onsemi if specified regulatory conditions are not met.

Insights

All-stock $7B Synaptics deal expands onsemi into Edge AI and connectivity.

onsemi plans an all-stock acquisition of Synaptics with an enterprise value of about $7 billion, using a fixed exchange ratio of 1.350 onsemi shares per Synaptics share. Synaptics holders are expected to own roughly 12% of the combined company after closing.

The companies highlight strategic fit: onsemi contributes power and sensing, while Synaptics adds Edge AI compute, user interface, and wireless connectivity. onsemi cites a potential increase in its total addressable market by $30 billion to $243 billion by 2030, contingent on execution and market development.

Regulatory and deal-completion risk is nontrivial. Closing is targeted for mid‑2027, subject to stockholder approval and multiple antitrust and foreign investment reviews. The agreement includes a $235 million termination fee owed by Synaptics in certain scenarios and a $320 million regulatory termination fee owed by onsemi if specified regulatory conditions are not satisfied, underscoring the importance of approvals.

Exchange Ratio financial
"equal to 1.350 (the “Exchange Ratio”) (the “Merger Consideration”)."
The exchange ratio is the number used to decide how many shares of one company you get for each share you own in another company during a merger or acquisition. It’s like a recipe that tells you how to swap shares fairly, ensuring both companies’ values are balanced. This ratio matters because it determines how ownership divides between the companies' shareholders.

"the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended"
Registration Statement on Form S-4 regulatory
"the effectiveness of the registration statement pursuant to which shares of onsemi Common Stock to be issued in the Merger will be registered with the U.S. Securities and Exchange Commission (the “SEC”)"
A registration statement on Form S-4 is a formal filing with the U.S. Securities and Exchange Commission used when a company issues shares or other securities as part of a merger, acquisition, exchange offer or similar corporate deal. It bundles the transaction terms, financial statements, risk factors and shareholder vote materials so investors can assess the deal; think of it as a detailed prospectus or buyer’s packet that explains what you would own and how the deal could change your stake.
termination fee financial
"will be required to pay onsemi a termination fee of $235,000,000."
A termination fee is a payment required if one party ends a contract before its agreed-upon end date. It acts like a penalty or compensation to the other party for canceling early, similar to a fee you might pay for breaking a lease or canceling a service contract. For investors, it matters because it can influence a company's decisions and financial obligations related to ending agreements prematurely.
regulatory termination fee financial
"will be required to pay Synaptics a regulatory termination fee of $320,000,000."
performance stock unit financial
"Each Synaptics performance stock unit (“Synaptics PSU Award”) that is outstanding but not vested immediately prior to the Effective Time"
A performance stock unit is a type of reward companies give to employees, usually managers, that depends on how well the company performs over time. If the company hits specific goals, the employee earns shares of stock, like earning a prize for reaching certain levels in a game. It motivates employees to work hard because their rewards are tied to the company's success.

Item 1.01
Entry into a Material Definitive Agreement.

Agreement and Plan of Reorganization

On June 25, 2026, ON Semiconductor Corporation (“onsemi”) entered into an Agreement and Plan of Reorganization (the “Merger Agreement”), by and among onsemi, a Delaware corporation, Sonic Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of onsemi (“Merger Sub”), and Synaptics Incorporated, a Delaware corporation (“Synaptics”). Pursuant to the Merger Agreement, and subject to the satisfaction or waiver of the conditions specified therein, Merger Sub will merge with and into Synaptics (the “Merger”), with Synaptics surviving the Merger as a wholly owned subsidiary of onsemi. Capitalized terms used but not defined herein have the meanings specified in the Merger Agreement.

onsemi’s Board of Directors has unanimously approved the Merger Agreement and the issuance of common stock, par value $0.01 per share, of onsemi (“onsemi Common Stock”) in connection with the Merger.

Merger Consideration

At the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.001 per share, of Synaptics (“Synaptics Common Stock”) outstanding immediately prior to the Effective Time (other than shares held by Synaptics, any Synaptics subsidiary, onsemi, any onsemi subsidiary, or Merger Sub, which will be cancelled) will be converted into the right to receive a number of validly issued, fully paid and non-assessable shares of onsemi Common Stock, equal to 1.350 (the “Exchange Ratio”) (the “Merger Consideration”). No fractional shares of onsemi Common Stock will be issued in the Merger, and Synaptics stockholders will receive cash in lieu of any fractional shares, as specified in the Merger Agreement. No appraisal, dissenters’ or similar rights will be available to holders of Synaptics Common Stock under applicable law, including Section 262 of the DGCL, in connection with the Merger.

If the Merger is consummated, Synaptics Common Stock will be delisted from the Nasdaq Stock Market LLC (“Nasdaq”) and deregistered under the Securities Exchange Act of 1934, as amended. The Exchange Ratio is expected to result in Synaptics equityholders owning approximately 12% of the combined company on a pro forma basis following the closing of the transactions contemplated by the Merger Agreement (the “Closing”).

Treatment of Synaptics Equity Awards

Pursuant to the Merger Agreement, at the Effective Time, each Synaptics restricted stock unit (“Synaptics RSU Award”) that is outstanding but not vested immediately prior to the Effective Time and held by an individual who, immediately after the Effective Time, constitutes an employee of onsemi within the meaning of Form S-8, will be assumed by onsemi and converted into a restricted stock unit award denominated in shares of onsemi Common Stock, covering a number of shares of onsemi Common Stock equal to the product, rounded to the nearest whole number, of the number of shares of Synaptics Common Stock underlying such Synaptics RSU Award multiplied by the Exchange Ratio, subject to the same terms and conditions as applied immediately prior to the Effective Time. Each Synaptics RSU Award that is (A) vested but not yet settled as of immediately prior to the Effective Time, (B) by its terms becomes vested in connection with the Closing or (C) is held by a non-employee member of Synaptics’s board of directors (the “Synaptics Board”) as of immediately prior to the Effective Time will be cancelled, and the former holder will have the right to receive an amount of Merger Consideration equal to the product of the Exchange Ratio and the applicable number of shares of Synaptics Common Stock subject to such award.


Each Synaptics performance stock unit (“Synaptics PSU Award”) that is outstanding but not vested immediately prior to the Effective Time and held by an individual who, immediately after the Effective Time, constitutes an employee of onsemi within the meaning of Form S-8, will be assumed by onsemi and converted into a performance-based stock unit award denominated in shares of onsemi Common Stock, covering a number of shares of onsemi Common Stock equal to the product, rounded to the nearest whole number, of the number of shares of Synaptics Common Stock underlying such Synaptics PSU Award multiplied by the Exchange Ratio, subject to the same terms and conditions as applied immediately prior to the Effective Time, except that for purposes of determining the number of shares of Synaptics Common Stock subject to each such converted Synaptics PSU Award, the applicable performance conditions for Synaptics PSU Awards for which the performance period has not yet closed will be deemed satisfied at target level, subject only to the time-based vesting conditions. Each Synaptics PSU Award that is (A) vested but not yet settled as of immediately prior to the Effective Time, (B) by its terms becomes vested in connection with the Closing or (C) is held by a non-employee member of the Synaptics Board as of immediately prior to the Effective Time will be cancelled, and the former holder will have the right to receive an amount of Merger Consideration equal to the product of the Exchange Ratio and the applicable number of shares of Synaptics Common Stock subject to such award, determined as if the performance conditions were satisfied at target level for Synaptics PSU Awards for which the performance period has not yet closed.

Each Synaptics market stock unit (“Synaptics MSU Award”) that is outstanding immediately prior to the Effective Time, which constitutes a Non-Vested MSU, and is held by an individual who, immediately after the Effective Time, constitutes an employee of onsemi within the meaning of Form S-8, will be assumed by onsemi and converted into a restricted stock unit award denominated in shares of onsemi Common Stock, covering a number of shares of onsemi Common Stock equal to the product, rounded to the nearest whole number, of the number of shares of Synaptics Common Stock underlying such Synaptics MSU Award (with such number determined based on actual performance of the performance conditions applicable to such Synaptics MSU Award as of immediately before the Closing) multiplied by the Exchange Ratio, and otherwise subject to the same terms and conditions as applied immediately prior to the Effective Time. Each Synaptics MSU Award that is (A) vested but not yet settled as of immediately prior to the Effective Time, (B) by its terms becomes vested in connection with the Closing or (C) is held by a non-employee member of the Synaptics Board as of immediately prior to the Effective Time will be cancelled, and the former holder thereof will have the right to receive an amount of Merger Consideration equal to the product of the applicable number of shares of Synaptics Common Stock subject to such award, determined based on actual performance of the applicable performance conditions as of immediately before the Effective Time and the Exchange Ratio.

If the treatment specified in the Merger Agreement for a non-U.S. grantee would be otherwise prohibited, subject to onerous regulatory requirements, or subject to adverse tax treatment under applicable law, onsemi may provide compensation equivalent in value to the non-U.S. grantee in the form of a cash payment, reduced by applicable taxes, or a new equity award, as reasonably determined by onsemi in consultation with Synaptics.

Governance

At the Closing, onsemi will appoint one independent director, designated by onsemi from among those directors serving on the Synaptics Board as of immediately prior to the Effective Time that have been proposed to onsemi by the Synaptics Board for consideration.

Closing Conditions

Completion of the Merger is subject to certain customary closing conditions, including, among other things, (1) the adoption of the Merger Agreement by the holders of a majority of the shares of Synaptics Common Stock outstanding and entitled to vote (the “Required Synaptics Stockholder Vote”), (2) the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the approval of the Merger under certain other antitrust and foreign investment regimes, (3) the absence of any order, injunction or law of certain jurisdictions prohibiting the Merger, (4) the effectiveness of the registration statement pursuant to which shares of onsemi Common Stock to be issued in the Merger will be registered with the U.S. Securities and Exchange Commission (the “SEC”), (5) the approval for listing on Nasdaq of shares of onsemi Common Stock to be issued in the Merger, (6) the accuracy of the other party’s representations and warranties, subject to certain standards set forth in the Merger Agreement, (7) compliance in all material respects with the other party’s covenants and other obligations under the Merger Agreement, (8) the absence of a continuing material adverse effect with respect to each of onsemi and Synaptics, and (9) the receipt by each party of customary closing tax opinions regarding the intended tax treatment of the Merger. The parties anticipate the transaction to close in mid-2027.


No Solicitation; Board Recommendation

Synaptics has agreed not to (a) solicit proposals relating to alternative acquisition transactions or (b) enter into discussions or negotiations or provide non-public information in connection with any proposal for an alternative acquisition transaction from a third party, subject to certain exceptions to permit the Synaptics Board to comply with its fiduciary obligations. Synaptics has further agreed to cease and cause to be terminated any existing discussions or negotiations, if any, with regard to alternative acquisition transactions. However, subject to the conditions specified in the Merger Agreement, prior to receipt of the Required Synaptics Stockholder Vote, the Synaptics Board may consider and ultimately change its recommendation with respect to, and may terminate the Merger Agreement in response to, an unsolicited, bona fide acquisition proposal that the Synaptics Board determines in good faith constitutes a Superior Proposal, subject to customary match rights. The Synaptics Board may also change its recommendation in response to an Intervening Event.

Termination and Fees

The Merger Agreement may be terminated under certain circumstances, including (1) by either onsemi or Synaptics if the Merger is not completed by June 25, 2027, which date may be extended for up to three periods of three months each, in each case under certain circumstances (the “End Date”), (2) by either onsemi or Synaptics if any court or governmental authority of a specified jurisdiction has issued a final non-appealable order or injunction prohibiting the Merger, (3) by onsemi prior to the Required Synaptics Stockholder Vote if the Synaptics Board fails to include in its proxy statement its recommendation to its stockholders to vote in favor of the adoption of the Merger Agreement or changes its recommendation, (4) by Synaptics prior to the Required Synaptics Stockholder Vote in order to accept a Superior Proposal (subject to payment of a termination fee, described below), (5) by either onsemi or Synaptics if Synaptics fails to receive the Required Synaptics Stockholder Vote at its stockholder meeting (including any adjournments and postponements thereof), or (6) by either party if the other party materially breaches its covenants, or breaches its representations and warranties, in the Merger Agreement such that the applicable conditions to closing would not be satisfied, subject in certain cases to the right of the breaching party to cure the breach. onsemi and Synaptics may also terminate the Merger Agreement by mutual written consent.

Upon termination of the Merger Agreement, Synaptics, under specified circumstances, including termination by Synaptics to accept a Superior Proposal or by onsemi following a change in recommendation by the Synaptics Board, will be required to pay onsemi a termination fee of $235,000,000. Additionally, onsemi, under specified circumstances, including termination following an injunction arising in connection with certain antitrust or foreign investment laws, or failure to receive certain required regulatory approvals of specified governmental authorities by the End Date, will be required to pay Synaptics a regulatory termination fee of $320,000,000.

Other Terms of the Merger Agreement

The Merger Agreement contains customary representations, warranties and covenants made by each of the parties, including, among others, covenants regarding the conduct of onsemi’s and Synaptics’s businesses during the pendency of the transaction, the making of certain public disclosures and other matters as described therein. Subject to the terms and conditions of the Merger Agreement, the parties have agreed to use reasonable best efforts to take all actions reasonably necessary to consummate the Merger, including obtaining all required or necessary consents, approvals or waivers from third parties, and cooperating to obtain the regulatory approvals necessary to complete the Merger.


The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1, which is incorporated herein by reference. A copy of the Merger Agreement has been included to provide onsemi stockholders and other security holders with information regarding its terms and is not intended to provide any factual information about onsemi, Synaptics, Merger Sub or their respective affiliates. The representations, warranties and covenants contained in the Merger Agreement have been made solely for purposes of the Merger Agreement and as of specific dates; were made solely for the benefit of the parties to the Merger Agreement; are not intended as statements of fact to be relied upon by onsemi stockholders or other security holders, but rather as a way of allocating the risk between the parties in the event the statements therein prove to be inaccurate; have been modified or qualified by certain confidential disclosures that were made between the parties in connection with the negotiation of the Merger Agreement, which disclosures are not reflected in the Merger Agreement itself; may no longer be true as of a given date; and may apply standards of materiality in a way that is different from what may be viewed as material by onsemi stockholders or other security holders. onsemi stockholders and other security holders are not third-party beneficiaries under the Merger Agreement (except under limited circumstances as set forth in the Merger Agreement) and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of onsemi, Synaptics, Merger Sub or their respective affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in onsemi’s public disclosures. onsemi acknowledges that, notwithstanding the inclusion of the foregoing cautionary statements, it is responsible for considering whether additional specific disclosures of material information regarding material contractual provisions are required to make the statements in this Current Report on Form 8-K not misleading. The Merger Agreement should not be read alone but should instead be read in conjunction with the other information regarding the Merger Agreement, the Merger, onsemi, Synaptics, Merger Sub, their respective affiliates and their respective businesses, that will be contained in, or incorporated by reference into, the registration statement on Form S-4 and proxy statement/prospectus that onsemi and Synaptics will file, as applicable, as well as in the Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings that onsemi will make with the SEC.

Cautionary Note Regarding Forward-Looking Statements

This communication relates to a proposed business combination transaction between Synaptics and 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 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.

Exhibit 99.1

onsemi to Acquire Synaptics to Enable the Next Generation of Intelligent Systems for Physical AI

Accelerates onsemi’s evolution, building on its strength in power and sensing to become a leading provider of intelligent systems — expanding from AI data centers into Physical AI

Increases onsemi’s total addressable market by $30 billion to $243 billion by 2030

Positions onsemi at the intersection of Power, Sense, Connected Compute and Control — the four pillars of Physical AI — which enable machines to sense, decide, act and adapt in the physical world

Would combine complementary portfolios to drive significant customer value and deepen customer engagements

SCOTTSDALE, Ariz. & SAN JOSE, Calif. – June 25, 2026 onsemi (Nasdaq: ON) and Synaptics Incorporated (Nasdaq: SYNA) today announced they have entered into a definitive agreement under which onsemi has agreed to acquire Synaptics in an all-stock transaction, representing a total enterprise value of approximately $7 billion. The transaction value reflects a fixed exchange ratio of 1.350 shares of onsemi common stock for each Synaptics share and represents an approximately 19% premium to the volume weighted average closing prices of onsemi and Synaptics over the last 10 trading days.

The combination would accelerate onsemi’s evolution toward global leadership in intelligent systems. By adding Synaptics’ differentiated Edge AI compute franchise and strong portfolio of human-machine interface and wireless connectivity solutions, onsemi is expected to extend its capabilities beyond power and sensing to intelligent systems, delivering greater value to a broad range of end markets. Building on onsemi’s expertise in automotive, industrial and AI data center, the combined platform is intended to position onsemi at the center of Physical AI, with the potential to expand onsemi’s TAM by $30 billion to $243 billion by 2030.

“As artificial intelligence moves beyond the cloud and into the physical world, including automotive and industrial, the next phase of innovation will depend on systems that can sense, decide, act and adapt in real time,” said Hassane El-Khoury, President and CEO of onsemi. “This shift towards Physical AI will require Power, Sense, Connected Compute and Control to work together seamlessly. The addition of Synaptics helps position onsemi at the intersection of these four pillars, enabling us to capture a significantly larger AI opportunity that extends beyond AI data center and into edge applications. This transaction would add immediate connected compute capabilities, expand our software and ecosystem reach and position onsemi to deliver greater value as customers increasingly seek intelligent systems.”

“Today’s announcement marks an important step in accelerating Synaptics’ growth and leadership in Edge AI and Physical AI,” said Rahul Patel, Synaptics President and CEO. “Together with onsemi, we will combine Synaptics’ strengths in AI-native compute, connectivity, and human-machine interface with onsemi’s leadership in intelligent power and sensing to offer customers integrated solutions and development platforms across every layer of the Edge AI stack, deepening customer engagement and expanding across a greater total addressable market. The all-stock structure allows our shareholders to participate in the compelling growth and value creation opportunities ahead, and I look forward to working with the onsemi leadership team to help realize the full value of this combination.”

Compelling Strategic and Financial Rationale

The combination is expected to deliver substantial value:

Enables capabilities from AI Infrastructure to Physical AI: onsemi is already well-positioned across the AI infrastructure ecosystem, from the energy grid to the data center core. This transaction is expected to extend that reach to the intelligent edge, enabling onsemi to address additional end markets while enhancing its capabilities to become a provider of integrated, system-level solutions across Power, Sense, Connected Compute and Control. This compelling combination would enable systems that can sense, decide, act and adapt in real time across Physical AI applications, including autonomous driving, robotics, and AR/VR.


Adds a proven, scalable Edge AI connected compute platform to onsemi: Synaptics’ Astra platform combines purpose-built AI processors and NPUs for multimodal intelligence with an industry-leading wireless connectivity portfolio spanning Wi-Fi, Bluetooth and GPS and a full open-source software stack for rapid deployment.

Complementary portfolios designed to unlock significant revenue growth with scale: The combination of two highly complementary portfolios would allow onsemi to accelerate its innovation and product roadmap to capture higher dollar content per platform while fostering deeper long-term customer engagement. This is anticipated to increase onsemi’s exposure to higher-value, differentiated system solutions with embedded IP and software, supporting improved mix, margin expansion and durable growth.

Attractive financial profile: The transaction is expected to be accretive to non-GAAP EPS within 18 months of closing, with an expected $200 million in annual synergies and gross margins consistent with onsemi’s long-term financial model. onsemi remains committed to maintaining its existing capital return policy during the pendency period.

Transaction Details

Under the terms of the agreement, which has been unanimously approved by the Boards of Directors of both companies, Synaptics stockholders will receive 1.350 shares of onsemi common stock for each share of Synaptics common stock held at the time of closing, implying pro forma ownership of approximately 12% for Synaptics stockholders on a fully diluted basis.

As part of the transaction, one member of the Synaptics Board of Directors is expected to join onsemi’s Board of Directors.

The transaction is expected to close in mid-2027, subject to approval by Synaptics stockholders, the receipt of required regulatory approvals and other customary conditions.
