CODE OF CONDUCT

1. PURPOSE – OUR COMMITMENT TO INTEGRITY AND TRUST

The Board of Directors of Synaptics Incorporated (together with its subsidiaries, the "Company") has adopted this Code of Conduct (the "Code") in order to promote honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest; promote full, fair, accurate, timely and understandable disclosure in reports and documents that the Company files with, or submits to, the Securities and Exchange Commission (the "SEC") and in other public communications made by the Company; promote compliance with applicable governmental laws, rules and regulations; promote the protection of Company assets, including corporate opportunities and confidential information; promote fair dealing practices; deter wrongdoing; and ensure accountability for adherence to the Code.

At Synaptics, integrity, trust, honesty, respect and accountability guide how we do business worldwide. We are committed to conducting our business ethically, lawfully, and responsibly in every market where we operate. Our Code is foundational to how we do business and how we put our values into practice each and every day. It applies to every business decision in every area of the company worldwide.

This Code applies to all directors, officers, and employees of Synaptics and its subsidiaries (collectively, “Synaptics Personnel”). It sets forth the principles and standards that govern the conduct of Synaptics Personnel in their decisions, actions, and relationships with customers, suppliers, partners, investors, communities, and each other.

This Code cannot address every situation that may arise. When questions or concerns occur, we rely on sound judgment, professional integrity, and guidance from our Legal, Finance, and Human Resources teams. Speaking up when something does not seem right is a shared responsibility and an essential part of our culture. Any suspected violations should be reported as described under Section 13 below.

2. ADDITIONAL RESPONSIBILITIES OF SENIOR FINANCIAL OFFICERS

In addition to the standards set forth in this Code, Synaptics’ Chief Executive Officer, Chief Financial Officer, principal accounting officer, and other senior financial officers have heightened responsibilities due to their role in the Company’s financial reporting and public disclosures.

Senior financial officers are expected to promote honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest; ensure that financial records and disclosures are accurate, complete, timely, and understandable; comply with applicable laws, rules, and regulations governing financial reporting and disclosures; maintain effective disclosure controls and internal controls; and promptly bring to the attention of the Audit Committee (i) any material information that may affect the Company’s public disclosures or financial reporting; (ii) any significant deficiencies or material weaknesses in the design or operation of internal controls; or (iii) any fraud, whether or not material, involving management or other employees who have a significant role in the Company’s financial reporting, disclosures, or internal controls; and foster a culture of integrity and accountability within the finance organization.

Any violations of this Code by the Chief Executive Officer or any senior financial officer will be reviewed and addressed by the Board of Directors or a committee thereof. Any waiver of these provisions for a senior financial officer may be made only by the Board or a committee thereof and will be publicly disclosed as required by applicable law and Nasdaq listing rules.

3. ETHICAL BEHAVIOR AND COMPLIANCE WITH LAWS

Synaptics is committed to full compliance with all applicable laws, rules, and regulations wherever we operate. Synaptics Personnel are required to comply, both in letter and spirit of all applicable laws, rules and regulations in the cities, states and countries in which the Company operates (collectively, “Applicable Laws”). Although not all Synaptics Personnel are expected to know the details of all Applicable Laws, it is important to know enough to determine when to seek advice from appropriate personnel. Examples of expected compliance include:

4. RESPONSIBLE SUPPLY CHAIN PRACTICES

Synaptics is committed to conducting business responsibly and expects its suppliers, contractors, and business partners to uphold standards consistent with our values and Applicable Law. These expectations are set forth in the Supplier and Vendor Code of Conduct (“Supplier CoC”), which is administered separately and applies specifically to third parties, which this Code applies to all Synaptics Personnel. Synaptics Personnel with supplier-facing responsibilities are expected to support compliance with the Supplier CoC and to escalate potential human rights or labor concerns through appropriate Company channels.

5. HUMAN RIGHTS AND LABOR PRACTICES

We are committed to maintaining a safe, healthy, and respectful workplace which is essential to Synaptics’ success. We are committed to fostering an environment of mutual respect, honesty, and openness, where each employee is treated as a valid contributor, and where individuals are treated fairly, can work without fear of bullying, harassment or discrimination, and can perform their jobs safely and effectively. Each of us is responsible for upholding these standards in our actions, decisions, and interactions whenever we represent Synaptics.

6. PRIVATE EMPLOYEE INFORMATION AND USE OF COMPANY SYSTEMS

Synaptics Personnel must respect the privacy of current and prospective employees. Personal information relating to a coworker or job applicant, including identification numbers, health information, performance or disciplinary records, or other sensitive data, may be accessed, used, or shared only for legitimate business purposes and only by individuals with an authorized need to know. Such information must not be disclosed unless permitted by law, authorized by the individual, or approved through appropriate Company channels. Nothing in this Code is intended to restrict rights related to protected concerted activity. Synaptics does not monitor or interfere with lawful union activities or other protected concerted activities.

Subject to Applicable Laws and Company policies, Synaptics may monitor, access, review, retain, or disclose information created, stored, transmitted, or accessed using Company systems, networks, devices, or facilities, regardless of whether the device is Company-owned or personally owned but used for Company business. This may include electronic communications, files, usage data, physical workspaces, and other Company resources. Monitoring and review activities are conducted for legitimate business, security, legal, and compliance purposes. Monitoring and review activities also are conducted in accordance with Applicable Law, and additional local notices or consents may apply in certain jurisdictions.

Employees should not expect privacy when using Company systems, networks, or resources, including remote access tools or virtual private networks, except as required by Applicable Law. Limited personal use of Company systems may be permitted in accordance with Company policy, but such use remains subject to monitoring and review.

The appropriate use of Company systems, networks, devices, and information resources is governed by Synaptics’ Acceptable Use Policy and related information security and privacy policies. Questions or concerns regarding privacy, monitoring practices, or the handling of personal information should be directed to the privacy function in the Legal Department.

7. DEVELOP AND DEPLOY RESPONSIBLE AI

We are committed to developing and deploying AI technologies in a way that is consistent with our principles. We strive to create systems that people trust. This means keeping people and their goals at the center of system design decisions and respecting enduring values like fairness, reliability and safety, privacy and security, inclusiveness, transparency, and accountability.

We develop and deploy responsible AI by following the Synaptics Responsible Use of AI Policy when developing and deploying AI technologies, by reporting sensitive and higher risk uses to the Legal department and following the guidance you receive. Examples of sensitive and higher risk uses include, without limitation, employment-related decisions, biometric identification, surveillance, personally identifiable information, Synaptics’ confidential information, safety-critical systems, or regulated product. When in doubt, check with Legal for guidance before proceeding.

8. SUSTAINABILITY EFFORTS AND COMMUNITY SUPPORT

We recognize the importance of protecting the environment for future generations and ensuring we all can attain a healthy and enriched life. We reduce our environmental footprint and prevent environmental pollution by complying with all applicable environmental laws and regulations and by continually improving our environmental management systems. We are committed to minimizing natural resource consumption, improving sustainability, reducing waste and increasing reuse and recycling programs, disposing of end-of-life products in an environmentally safe and responsible manner, educating ourselves and monitoring our performance, and developing and marketing products that are safe for their intended use, efficient in their use of energy, protective of the environment, and that can be reused, recycled or disposed of safely.

We source our suppliers responsibly and require them to comply with internationally recognized health and safety and environmental standards, including standards relating to the use and disposal of hazardous substances.

We aim to positively influence, and take pride in our social responsibility to, our communities. We support our local communities worldwide by engaging with groups and organizations that reflect our high regard for social responsibility, by participating in relief efforts and charitable causes and events, and by volunteering at organizations that improve our communities.

9. PROTECTION OF COMPANY ASSETS AND CONFIDENTIAL INFORMATION

Each of us is responsible for safeguarding Synaptics’ assets and confidential information. Company assets include physical property, equipment, systems, data, intellectual property, and other resources entrusted to us in the course of our work. Protecting these assets is essential to Synaptics’ operations, reputation, and competitive position. Confidential Information includes non-public information relating to Synaptics’ business, products, services, operations, finances, strategies, customers, or employees, as well as confidential information entrusted to Synaptics by customers, suppliers, partners, and other third parties. Such information must be protected from unauthorized access, use, disclosure, or loss.

Synaptics Personnel must use confidential information solely for legitimate business purposes and share it only with individuals who have a business need to know. Disclosure of confidential information to third parties may occur only when authorized and subject to appropriate confidentiality protections, such as a non-disclosure agreement. Even within Synaptics, information should be shared thoughtfully and only to the extent necessary to perform assigned responsibilities.

Information received from third parties must be protected with the same care as Synaptics’ own confidential information. Misuse or improper disclosure of confidential information—whether belonging to Synaptics or to others—can result in legal liability, loss of trust, and disciplinary action.

Synaptics Personnel should remain mindful of their surroundings and communications, including conversations in public or semi-public settings and the use of electronic communications. Company assets and information must be protected against loss, theft, misuse, or unauthorized access at all times.

Nothing in this Code is intended to restrict rights under Applicable Law to discuss wages, hours, or other terms and conditions of employment. Questions regarding the handling or disclosure of confidential information, intellectual property, or other Company assets should be directed to Legal.

10. ACCURACY OF BUSINESS RECORDS AND FRAUD

Accurate, complete, and reliable business records are essential to Synaptics’ legal, financial, and operational integrity. Synaptics Personnel are responsible for ensuring that all records and communications—including financial records, expense reports, timekeeping records, technical and product documentation, customer information, and public or internal communications—are prepared honestly, accurately, and in a timely and understandable manner.

Falsification or improper manipulation of Company records is strictly prohibited. Fraud includes, among other things, altering records, misrepresenting facts, omitting material information, or assisting others in doing so for the purpose of misleading internal or external audiences.

All expenses must be incurred and reported in compliance with Company policies and applicable approval requirements. Expense reimbursement submissions must be accurate, complete, and supported by appropriate documentation, consistent with Synaptics’ travel and expense policies.

11. RECORDS MANAGEMENT & LEGAL HOLD

Records and information created or received in the course of Synaptics’ business are Company assets. Synaptics Personnel are responsible for creating, maintaining, retaining, and disposing of records in accordance with Applicable Laws and Company records management and retention policies. Records must be maintained in a manner that preserves their accuracy, integrity, confidentiality, and security. Retention periods may vary based on legal, regulatory, operational, or privacy requirements. In certain circumstances, records may be subject to preservation obligations, including legal holds. When a legal hold is in effect, relevant records must not be altered, deleted, destroyed, or concealed, including records stores in collaboration platforms, messaging tools, or personal devices used for Company business. Legal will provide guidance regarding any such requirements. Questions regarding records management or retention should be directed to Legal or the appropriate Company resources.

12. PUBLIC SPEAKING, MEDIA & EXTERNAL INQUIRIES; ENDORSEMENTS

Synaptics Personnel may not participate in public speaking engagements, panels, presentations, or other external communications that relate to Synaptics’ products, services, technology, or business—or that could reasonably be interpreted as representing Synaptics without prior approval from management and the appropriate Company communications functions.

Employees who are authorized to participate in approved engagements may not accept personal compensation in connection with such activities. Reasonable, directly related expenses may be accepted only in accordance with Company policy.

All inquiries from members of the media, industry analysts, investors, or other external parties seeking comment on behalf of Synaptics, or where an employee’s response could reasonably be attributed to the Company, must be directed to Corporate Communications or Investor Relations, in consultation with Legal, as applicable. Employees should not respond to such inquiries unless expressly authorized to do so.

Nothing in this Code is intended to restrict rights under Applicable Law to discuss wages, hours, or other terms and conditions of employment, or to raise concerns regarding workplace conduct. However, Synaptics Personnel must not disclose confidential or proprietary Company information in connection with any such communications.

You should never endorse a product or service of another business or individual in your role, unless the endorsement has been approved by your manager, Corporate Communications and Legal. This does not apply to statements made in the normal course of business about third-party products sold by Synaptics.

These principles also apply to the use of social media, blogs, forums, and other online platforms. Guidance regarding appropriate social media use is available on the Company’s intranet.

14. ACCOUNTABILITY, ENFORCEMENT AND TRAINING

Compliance with this Code is a condition of employment and service with Synaptics. Each Synaptics Personnel is required to read and understand our Code and all Synaptics policies. The Company provides annual training to employees and actively monitors and audits compliance with our Code. Violations may result in disciplinary action, up to and including termination of employment, as well as potential civil or criminal liability. This Code is administered by the Legal Department under the oversight of the Nominations and Corporate Governance Committee of the Board.

Employees are expected to promptly bring to the attention of the Chief Executive Officer, Chief Financial Officer, Chief Legal Officer or the appropriate standing committee of our Board any information that may affect the accuracy or completeness of the Company’s public disclosures, including evidence of fraud or material violations of law.

Each of the members of the Board or its designated committee (in the case of a violation by a director or executive officer) and the Chief Legal Officer (in the case of a violation by any other person) may, in his/her discretion, waive any violation of this Code. Any waiver for a director or an executive officer shall be disclosed as required by SEC and Nasdaq listing rules.

To inform employees of the requirements under this Code, Synaptics provides periodic training and each Synaptics Personnel required to take such training must acknowledge that they have received, understand the contents, and agree to comply with the policies and procedures set out in this Code.
