Keeping our promises Code of Conduct

For more than a century, Belden has been building connections. Our connections, both with our customers and each other, are based on trust and integrity. We earn and maintain that trust by following our Values. These Values guide us in all we do, ensuring we maintain our integrity while exceeding expectations for our customers and shareholders. Our Values apply across our business, and our Code of Conduct shows us how. It provides specific guidance and keeps us connected to our broader purpose as a business. In all we do, wherever we do business, we follow our Code. Read this Code and keep it on hand. Use it as a guide to your actions and decisions, and be aware of how your choices affect others. Though our Code is comprehensive, it cannot address every situation. If you are ever unsure about an ethical matter, ask questions. The resources in this Code will tell you where to start. Our Code will also tell you how best to report any concerns or violations. As the keepers of Belden’s legacy, we rely on each other to do what’s right. And we never retaliate against those who report violations of our Code or the law in good faith. When we follow our Values and our Code, we ensure the health of our business. Acting with integrity protects Belden’s reputation so that we can be an industry leader well into the future. As we continue to reach for greatness, we must always do what is right.

How to use our Code Our success in keeping our promises depends on the daily choices we make. Our Code of Conduct is the tool we rely on to choose what is right and bring our Values to life. Our Values Our promises to employees Our promises to customers Our promises to shareholders Our promise to uphold the law Our promises for the future Where to go for help 5 How to use our Code

Our Code Every day at Belden presents new opportunities — ways for us to innovate and design for the future. As employees, we stretch ourselves and our capabilities, never standing still. We work in an exciting place and in a variety of increasingly complex industries. When those complexities involve ethical challenges, the right course of action may not always be clear. That’s why we have our Code of Conduct — to help guide you as you use your best judgment to make the best decisions for our Company, customers and share- holders. While the Code cannot address every possible situation, it is the best place for you to start. It offers simple and sound advice on upholding the laws that apply to our business and bringing unquestionable integrity to all of our daily interactions. What’s in the Code? • Overviews of ethical topics and why they are important to our business • The promises we make and the actions we take to fulfill them • “Our policy in practice” —  real ethical situations you could face • Links to our policies for more information • Decision-making tools and important points to consider • Resources to contact for more help The Code is for all of us That means everyone who works on Belden’s behalf must live up to the same high standards and comply with the Code, our policies and the laws that apply to our business. In other words, no matter your role at Belden, the Code applies to you — with no exceptions. It includes all employees of Belden’s subsid- iaries and affiliates, full-time and part-time employees, senior leaders, officers and directors, and contractors — at every location around the world. In addition, employees receive a copy of the Code and are required to acknowledge receipt of this Code and agree to abide by it at the start of employment and annually thereafter. Waivers or changes to the Code As laws change, Belden may make occasional updates to the Code or grant limited waivers. Belden’s Board of Directors has oversight responsibility for this Code. The Nominating and Corporate Governance Committee of the Board will periodically review and assess the appropriateness of the principles and policies herein and make recommendations to the Board in consultation with Belden’s Compliance Team, as appropriate. Waivers happen rarely and may only be made and approved by the Board of Directors. We will disclose any waivers promptly to shareholders, in compliance with all applicable laws, rules and regulations.

Our responsibilities As you read through the Code, you will discover what “Keeping our promises” means to Belden. The first step is understanding what the Company expects from you. Each of us shares the responsibility to: • Live our Values. Embrace our Values and let them guide every action. Also read and follow the Code and any policies that apply to your work. • Learn about the law. Our business is subject to a variety of laws and regulations. Learn those that apply to you and ask questions if you are ever unsure what is required. • Speak up for what is right. Stay alert for any activity that breaks our promises or appears to violate our Code, policies or the law. That means voicing your concerns if you believe or suspect that a violation has happened. If you are a manager, you have added responsibilities: • Set the best example. Since your team looks to you as a model of good behavior, let them see you reflecting our Values and following our Code in everything you do. • Be there to help. When your team has questions or wants to talk, make time for them. Know the Code well and be able to answer questions about it or refer them to other resources for help. • Act quickly. If you learn about or suspect possible misconduct, do not wait. Voice your concerns right away to the appropriate resource. • Enable your team to follow the Code. Consistently apply the principles of the Code and do not tolerate retaliation against any reporting employee.

Making ethical decisions Belden expects us to use our best judgment and make good decisions, but there may be times when the right choice is not clear. If that happens, ask yourself these questions: • Is this action legal? • Is it a good reflection of our Values? • Is it good for Belden and our customers? • Does it align with our Code and our policies? • Would I be comfortable telling others about my actions? The best possible outcome is being able to answer “yes” to every question. That means the action you are considering is probably okay. If you answer “no” or “maybe” to any of them, pause and reconsider. An even better option: ask for help before taking any action. Help someone else Sometimes a coworker may be wondering what to do — or even worse, about to take a wrong turn. Do not watch it happen. Talk to them and point them back to our Code and our policies — or to a resource where they can get help. Our Values Our promises to employees Our promises to customers Our promises to shareholders Our promise to uphold the law Our promises for the future Where to go for help 8 How to use our Code

Violating our Code When someone violates Belden’s Code, our policies or the law, they also fail to live up to our Values and can risk damaging our reputation and relationships. The same is true if you ignore someone else’s misconduct —  it can cause just as much harm. Belden takes violations seriously. That is why it is so important to voice your concerns if you become aware of possible misconduct. If an investigation reveals a violation of our Code, the consequences can be serious. We will take appropriate disciplinary action — even up to dismissal. If a law has been broken, those involved could also face civil or criminal fines or other penalties. Our Values Our promises to employees Our promises to customers Our promises to shareholders Our promise to uphold the law Our promises for the future Where to go for help 9 How to use our Code

Voicing your concerns One of the most important things you can do for Belden is speak up when you think you see something wrong. This means letting us know right away if you become aware of something that goes against our Values or violates our Code, policies or the law. Even if you are not sure if an action is really a violation, it is vital to voice your concerns. Where should I turn? We understand it can sometimes be difficult to share a concern, but there are a variety of options available to you: • Your manager • Human Resources • The Compliance Team, which includes the Legal Department and the Internal Audit Department. This team can be reached via email: ombudsman@belden.com • Our ethics and compliance Hotline, which is available 24 hours a day, seven days a week: • By phone at 1-800-461-9330 in the United States and Canada • Or online at www.belden.com/ethics NOTE: Our ethics and compliance Hotline is powered by a third- party platform. When you visit the website, you will find a list of local phone numbers for areas outside the U.S. and Canada as well as a link to the Belden associate Compliance Portal. Regardless of the option that you choose, we will take your report seriously, treat it confidentially (to the extent possible) and address it promptly. You can even report anonymously through the Hotline, wherever permitted by law. Then what happens? After you report a concern, it immediately goes to the appropriate Company represen- tative for a confidential review. Keep in mind that only the people who need to know about your report will see it. Then we decide if it should be investigated. If an investigation is warranted, it is referred to the appropriate team. Most of the time, you will not hear specific details of an investigation, but we will make every effort to notify you of the results. Your right to speak We support your right to speak out publicly about matters of public concern or engage in certain activities related to the terms and conditions of your employ- ment. Nothing in this Code or in any of our policies is intended to limit or interfere with your right to engage in concerted activities protected under Section 7 of the U.S. National Labor Relations Act or any other applicable law in any country in which Belden operates, such as discussions related to wages, hours, working conditions, health hazards and safety issues.

Our non-retaliation policy We want you to feel confident and secure voicing your concerns. That is why we will never tolerate retaliation of any kind against you for reporting something in good faith or cooperating with an investigation. What matters is that you sincerely believe your report to be true —  or you are concerned enough to let us know about it. By identifying risks early, we prevent harm from being done to Belden employees, customers or anyone else impacted by our business. Voice your concerns if you believe you or anyone else has experi- enced some kind of retaliation, which could include dismissal, demotion, reassignment or any other retaliatory act. Did you know? Retaliation itself is a violation of our Code and will result in disciplinary action, including possible termination. Our policy in practice Q I am concerned that one of my coworkers may have done something that violates our Code, and I would like to report it. But because we work in a small team, this person will probably know it was me. What should I do? A You should voice your concerns right away. If you suspect a violation, you have a responsibility to let us know. That is the only way we can identify something harmful and take action to address it. If nobody speaks up, more harm could be done. Remember, we will handle the information discreetly, and we will not tolerate retaliation against you for voicing a concern.

Respect and inclusion Our promise We work together as one team. We are welcoming and respectful of all employees, and we never harass or discriminate.

Employee privacy and data protection Our promise We value and protect the data we collect from our employees in the course of doing business. We respect data privacy, and we never compromise our data security. Our reasons When we do business, we deal with data — often personally identifiable information (PII) and data capable of identifying one of our employees (Personal Information). Keeping that information private is essential to our relationships with employees, so we handle it carefully and in compliance with privacy laws, including, but not limited to, the European Union’s GDPR regulation and similar laws around the world. By respecting employee privacy, we maintain trust. Our actions We protect data and respect employee privacy when we: • Know and follow all privacy laws related to the handling, storage and disposal of PII and Personal Information, wherever we do business • Access PII and Personal Information for appropriate business purposes only • Gather and store only the information needed, and no more • Never share PII or Personal Information without an appro- priate legal basis to do so (such as data subject permission or business necessity), and then only share with those who need to know for business purposes • Ensure our business partners treat PII and Personal Information in accordance with our policies and the law • Store PII and Personal Information on approved Belden networks, and follow our cybersecurity and data classification procedures to keep data systems secure • Take particular care with sensitive personal data, including, but not limited to, health information • Respect data subject requests to access PII and Personal Information to the extent permitted by applicable privacy laws and regulations • Complete all required cyber- security and data protection training in a timely manner • Contact the Data Privacy Team (belden.privacy@belden.com) or our corporate ombudsman (ombudsman@belden.com) with any questions or concerns, or if an unauthorized disclosure of PII or Personal Information occurs All of the above applies equally to PII or Personal Information we hold about our customers, business parties and third parties.

Employee privacy and data protection / continued Our policy in practice Q I received an email from a customer requesting the home address for my coworker, who has been out sick. They want to send a get-well card and flowers. Because they know each other, is it okay to share this information? A No. Even though the customer may have a working relationship with this employee, you should never share an employee’s personal information with anyone who is not authorized and does not have a business need to know. Advise the customer to send a card to the office instead. Find out more Data Privacy Policy Belden Employee GDPR Information Page What Is PII and Personal Information?

The procedures we have in place already consider safety and quality. While we value and encourage continuous improvement of our processes, any changes to our procedures must be reviewed and approved before they can be implemented.

Fair dealing Our promise We compete fairly in the marketplace. We win business based on the high quality of our products, solutions and services — no exceptions. Our reasons At Belden, we play to win fairly. This means doing our best work with integrity and never seeking unfair or illegal advantages.

To know if a conversation with a competitor is inappropriate, ask yourself: Is this conversation about … • Fixing prices or terms of sale? • Excluding a new competitor? • Determining what products or services we offer? • Splitting markets, customers or territories? • Promoting a boycott? • Rigging the outcome of a bid? Answering “yes” to any of these means you should stop the conversation and report it right away.

Ethical government contracting practices Our promise Earning government business is a great privilege. We take this responsibility seriously and bring our high standards of integrity to the job. Our reasons Serving government customers and government-owned entities means serving the people who depend on those governments. We are transparent and accountable in all our business relationships but especially careful to follow the special rules and regulations that go along with government contracts. When we are trusted with public funds to provide products or services, we respond with integrity. Our actions We are ethical in our government contracting practices when we: • Meet all obligations and follow all contract specifications carefully, never substituting materials or vendors • Perform all required tests or inspections • Provide accurate and complete information regarding the use of public funds • Always ensure accuracy when required to charge our time on government contracts • Follow all rules and requirements for bidding on government contracts • Never offer anything of value, including gifts, entertainment or meals, to a government official • Follow all laws, regulations and policies that apply to government contracting Maintaining trust Violations of government contracting laws undermine trust in Belden. They can also lead to administrative, civil or even criminal penal- ties, both for Belden and for you. If you have a question about a government contract or any dealing with a government official, ask a manager, Human Resources or the Compliance Team for guidance before you act. Our policy in practice Q I work regularly with a government official on a particular contract. One day she mentioned that one of her children was looking for a job. She laughed and asked if Belden was hiring. She may have been joking. Still, would it be okay to refer her to an opportunity posted on our website? A No, it would not. Even if you did not initiate the conversation, mentioning an opportunity to a government official could violate the law and appear to be a bribe. Let this official know that hiring at Belden is handled through Belden’s regular application process.

Know your customer Our promise We are careful to verify the identity and reputation of our customers and business partners, within the law. We are responsible for ensuring that we do business with reputable entities. Our reasons We provide technology and services in a complex global marketplace. Some actors within that marketplace want to take advantage of good-faith businesses to accomplish corrupt or illegal goals. By ensuring that we know our customers and business partners, we protect Belden from corrupt and illegal practices and scams. Our actions We ensure that our business dealings are with reputable customers when we: • Take nothing at face value and verify communications and background information • Conduct appropriate due diligence and watch out for red flags to ensure that our customers and business partners are not engaged in money laundering, sanctions violations and other corrupt or illegal practices • Never sell to, buy from or otherwise do business with entities known to engage in bribery, money laundering or other corrupt or illegal practices • Never sell to, buy from or otherwise do business with entities or individuals on the denied or sanctioned parties lists maintained by the U.S. and other countries • Exercise caution and verify the identity of our contacts to avoid sophisticated phishing attempts using artificial intelligence (AI) Phishing and AI Phishing messages ask the recipient to send money or banking information to a fraudulent recipient. Such emails have often been easy to spot because of their errors. Using AI, phishing scams have become more sophisticated and more targeted. They can contain convincing messages that appear to be from a real person and mimic specific human voices and mannerisms.

Customer/third-party privacy and data protection Our promise Our customers and business partners often trust us with their data as part of doing business. We are transparent about what data and information we collect from them, and we protect it and only use it for legitimate business purposes. Our reasons Our business requires trust, collaboration and a great deal of shared information between Belden and those we work with, including our customers. To protect our reputation and maintain our business relationships, we must retain the trust we are given. That means protecting third-party confidential information from misuse or disclosure, and following all laws and regulations related to handling such information. Our actions We protect customer and third- party privacy and data when we: • Know and follow all privacy laws related to the handling, storage and disposal of PII and Personal Information, wherever we do business • Access PII and Personal Information for appropriate business purposes only • Gather only the Personal Information needed, and no more • Never share confidential information belonging to our customers, third parties or competitors without permis- sion, and even then, only on a need-to-know basis • Respect and protect all intellectual property, such as patents or trade secrets, that we may be exposed to as part of doing business • Access and store confidential and proprietary information using only secured networks and devices • Follow all procedures and protocols for data security, including using passwords and secure Company devices • Never install new software without first consulting IT • Follow all laws, policies and regulations related to data privacy, wherever we do business • Report any breaches of information security to the Data Privacy Team immediately • Complete all required cyber- security and data protection training in a timely manner Protect it like it belongs to us Treat others’ information with the same care that you would treat Belden’s information — or even your own. It is sensitive and valuable, so do not share it or allow it to fall into anyone else’s hands. Our policy in practice Q We recently hired a new employee, and during a team meeting, this individual shared information about a previous employer that sounded confidential. Is it okay to use this information to Belden’s advantage? A No, it is not. Let the new employee know that this information belongs to another organization and should not be shared. Be sure to let others who attended the meeting know the same thing. If you are uncomfortable speaking to the new employee or the meeting participants directly, ask your manager to intervene. Simply put, information from a previous employer is confidential. It is not ours, so we cannot use it.

Company assets / continued Our policy in practice Q Through my job, I have learned that Belden is developing a new product. Is it okay to share this news with my immediate family if I ask them to stay quiet about it? A No. This is confidential information, and you cannot rely on family members to protect it. Keep this information to yourself. Only discuss it when it becomes public knowledge or with those who have a legitimate business need to know. Find out more Copyright Policy Patent Policy Trademark Policy Trade Secrets Policy Recognize what to protect Our assets come in many different forms, but we are all responsible for protecting them. Depending on your role, you may use some assets more than others. At Belden, we use two main types of assets: information assets and physical and electronic assets. • Information assets include information we create and gather to innovate. Such information can be confidential information, intellectual property or both. • Confidential information is sensitive infor- mation about Belden, our customers or third parties. It is not available to the public and can be harmful if it is exposed. It can include information about: • Potential acquisitions • Capital investment plans • Marketing plans • Projected sales or earnings • New product ideas • Manufacturing methods • Third-party or customer lists • Employee lists and salaries • Intellectual property is anything that Belden or its employees create that makes us unique and competitive. It could include things like: • Product development plans • Software and manufacturing technology or know-how • Customer or supply lists • Designs, inventions or strategies • Copyrights and patents • Trade secrets, research or discoveries • Creative materials • Trademarks, brand names, slogans, taglines or logos • Physical and electronic assets are more tangible assets, or things Belden provides for business use.

Artificial intelligence Our promise We embrace innovative processes responsibly. When it comes to using artificial intelligence (AI) —  and all our technologies — we take the necessary precautions and mitigate against potential risks to our business. Our reasons Our customers and business partners trust us to deliver, and we keep our promises. AI and other emerging generative tools can aid us in our mission, but we must be responsible about how and when we use them and follow Belden’s rules for AI use. In addition, given the risks posed by AI, we must operate carefully and ethically wherever we use AI to do business. Our actions We use AI responsibly when we: • Ensure our AI processes follow data security protocols and regulations • Ensure that applicable intellec- tual property rights are always respected and protected when using AI • Never disclose the confidential, proprietary or export-controlled information of Belden or any other entity in the course of using AI systems • Never use AI for deceptive business practices • When required, obtain customer permission to use AI in carrying out our work • Disclose to customers and business partners any use of generative AI for business purposes, including in carrying out our work • Follow all AI-related laws, regulations and policies, wherever we do business Working with AI AI can help us process large volumes of data for specific purposes. But the results AI offers may not always be accurate and could violate the intellectual property rights of others. Furthermore, any data we input into AI is stored. This data can train AI and inadvertently be available to other users. As a result, we must follow Company procedures for using AI responsibly and must always take care not to release proprietary, sensitive, trade-secret or confidential information about Belden to the public in our use of AI. Our policy in practice Q I have been invited to write an article for a technical journal on cutting-edge innovation in signal transmission. It is a great opportunity to showcase our work at Belden. I would like to use AI to synthesize large amounts of data into a comprehensive article to save time. Is this a good idea? A By inputting data into AI, you make it available for AI to use for other purposes, potentially compromising our proprietary information or disclosing controlled technology. In addition, your article must be “original” in order to have copy- right protection. Check with the Compliance Team before using AI for this or any similar project.

Responsible communications Our promise As employees, we are careful to communicate responsibly with each other. As a company, Belden speaks with one voice when communicating with the media, investors and the general public. Our reasons The things we say about Belden have the potential to help or harm our business and our reputation. To ensure that we communicate with those outside of Belden in a way that is consistent, truthful and positive, we allow only designated personnel to speak on our Company’s behalf. This way, we avoid careless or inaccurate communication. Our actions We communicate responsibly when we: • Communicate internally in a helpful way, reflecting our Values and protecting people, information and our reputation • Never use our communications systems for personal purposes • Never speak on Belden’s behalf, either online or in public, unless authorized in advance to do so • Remain aware that the views we represent when using personal social media could be attributed to Belden, even if that is not our intention • Refer all outside inquiries to the appropriate Company resource Referring requests If you receive a request for comment by someone outside of Belden, choose one of these options: • Refer media requests to Corporate Communications • Refer financial questions to Investor Relations • Refer legal questions to the Compliance Team Find out more Public Relations Policy Social Media Guidelines Our Values How to use our Code Our promises to employees Our promises to customers Our promise to uphold the law Our promises for the future Where to go for help 28 Our promises to shareholders

Conflicts of interest Our promise We act in Belden’s best interests. We do not allow personal interests, activities, relationships or affiliations to influence the business decisions we make. Our reasons Conflicts of interest can compromise our objectivity when making business decisions. Even the appearance of a conflict of interest can damage our reputation. When we set our personal interests aside and practice unbiased decision- making, we make the best decisions for Belden and our business partners. Our actions We avoid conflicts of interest when we: • Make all business decisions objectively, without favoritism or bias • Remain alert to situations that may lead to a conflict of interest • Never participate in the hiring process for a family member, close friend or associate • Ensure that a family member, close friend or associate never reports to us • Never participate in the selection process for a supplier, vendor or contractor that employs a family member, close friend or associate • Disclose all potential conflicts of interest to a manager or the Compliance Team, or through our conflicts of interest disclosure process Our policy in practice Q One of the software engi- neers I work with has a great idea for a business. She asked if I wanted to help her get it off the ground and suggested we could start planning during our down time at Belden. Would that be okay? A No. We never use our time at Belden or any of Belden’s resources to pursue outside interests. If the business idea would compete directly with Belden, that would also present a conflict of interest. You should decline your coworker’s offer and report the situation to a manager. What is a conflict of interest? A conflict of interest may arise when an employee’s personal interests differ from those of Belden. Here are some common examples of conflicts of interest: • Significant ownership in or affiliation with a company that competes or does business with Belden • Accepting a role on an outside board that compromises your obligations to Belden • Taking a second job that takes time and energy away from your duties at Belden • Taking business opportunities for yourself that Belden may pursue • Using Belden’s name, property or information to support personal interests or activity • Supervising or making employment decisions regarding a family member, close family friend or associate If you find yourself facing a situation that might compromise your ability to make objective decisions on behalf of Belden, do not proceed. Talk to your manager or the Compliance Team. You may also use our conflicts of interest disclosure process. Disclosing a potential conflict of interest is the first step to finding a solution.

Appropriate business gifts and entertainment Our promise We never offer or accept inap- propriate gifts or entertainment in the course of doing business. Our business partnerships are based on the merits. Our reasons We value our business partner- ships and look for appropriate ways to strengthen them. However, the exchange of gifts and entertainment can create a conflict of interest or violate anti-bribery laws. We never accept gifts that are too lavish or too frequent because it could appear that someone is trying to gain an unfair business advantage. Our actions We are responsible with business gifts and entertainment when we: • Never ask for gifts or entertainment • Never accept cash or cash equivalents, including gift cards • Do not engage in any entertainment that could involve inappropriate or offensive content • Only accept gifts and entertainment that are legal, nominal in value and offered infrequently • Never accept gifts from a third party that is trying to secure business with Belden • Only offer nominal, noncash gifts that are approved by our policies, as a business courtesy • Accurately document any gifts we offer or receive Government officials The rules for gifts and entertainment are different for government officials. For this reason, we follow a stricter standard when doing business with governments. Regardless of local practice or your good intentions, you may not offer any business courtesy of any value to a government official unless you receive approval in advance. Our policy in practice Q One of our vendors has season tickets for the local sports team. He is unable to make it to the game this weekend and offered his two tickets to me. The tickets are not expensive. May I accept? A No. Even if the tickets are inexpensive, they do not serve a legitimate business purpose because you are not attending the game with the vendor. You should politely decline the offer.

Accurate records Our promise We keep complete and accurate records and provide true and timely information to stakeholders as required. The health of our business depends on it. Our reasons We cannot make sound business decisions without accurate records. Our records give us a clear and complete picture of our operations, and they provide reassurance to our stakeholders. They are also an essential guide to where we want to go as a business. We follow our policies and procedures as well as the law to be sure we maintain truthful, accurate records. Our actions We maintain accurate records when we: • Create honest and thorough records that include any required supporting documents • Comply with generally accepted accounting principles and all applicable laws and regulations • Classify records properly, in the correct account and accounting period • Never falsify or mischaracterize a record, or create undisclosed accounts • Provide complete, fair, accurate and timely disclosures to audits and investigations • Follow all policies and proce- dures for storing and disposing of records and information • Report any concerns about financial misconduct to a manager, Human Resources or the Compliance Team, or use our ethics and compliance Hotline Our policy in practice Q I believe a coworker has misrepresented the dates on some recent sales, attributing them to last quarter. Should I say something? A Yes. You should speak to your coworker to find out if they made an honest mistake. But if the person does not correct the error, talk to your manager, Human Resources or the Compliance Team. Inaccuracies in our books and records, if left uncorrected, can have consequences for our business. Any misrepresentation must be brought to light and resolved. Find out more Record Retention Policy What is a company record? At Belden, we keep many kinds of records. These include: • Accounting statements • Expense reports • Time cards • Emails and correspondence • Invoices and shipping records • Quotes and contracts • Safety reports and test results Some records need to be kept for longer than others. Our Record Retention Policy describes how and when to best dispose of a record. Legal holds In some situations, a record or records may be subject to a legal hold.

We comply with all legal holds and cooperate fully with investi- gations and audits.

Fraud prevention Our promise Fraud can hurt our operations and reputation as a business. We never engage in fraudulent or misleading practices, and we take extra care to prevent fraud by others. Our reasons Fraud diverts our resources as a business by unlawful and decep- tive means. When our resources or assets are misused, we are at a disadvantage in the industries where we compete. Our actions We prevent fraud when we: • Follow all internal controls and processes for financial approvals • Remain vigilant about identifying possible fraud- ulent behavior, including embezzlement, doctoring of records or scams • Keep strict and careful inventory records of all our products • Never make false or misleading entries in our accounts or records, for any reason • Follow all laws, regulations, policies and protocols for fraud prevention • Report any possible fraud immediately to a manager, Human Resources or the Compliance Team, or use our ethics and compliance Hotline What is fraud? Fraud is the use of deceit to gain a personal or business advantage. Though criminal itself, fraud is often used to cover up other illegal or unethical activity. Examples of fraud include, but are not limited to: • Falsifying financial records to embezzle funds • Reporting products as lost or stolen in order to steal them for personal use or resale • Providing fake or inflated invoices to finance kickbacks • Forging someone else’s signature to acquire funds or approve something improperly Our Values How to use our Code Our promises to employees Our promises to customers Our promise to uphold the law Our promises for the future Where to go for help 32 Our promises to shareholders

Ethical political and lobbying activities Our promise We support each employee’s right to participate in political activity. As a company, Belden follows all laws when engaging in the political process. Our reasons We strive for the best, both in our business and our communities. By getting politically involved, we play our part in making the world a better place. We are careful to participate lawfully, and we never allow our politics to interfere with our work respon- sibilities. We also never attempt to represent Belden in our political activity or gain political favor on Belden’s behalf. Our actions We engage in politics ethically when we: • Support causes and candidates on our own time, with our own resources • Avoid asking coworkers or other Belden staff for political contributions or seeking reimbursement for our contributions • Never represent our views as those of Belden, and never ask for or use Company funds or resources for political donations • Respect the political views of others, and never force our politics on coworkers • Never allow our political engagement to keep us from our work responsibilities • Never lobby on Belden’s behalf, or seek to gain favor for Belden from political figures The influence of managers Managers should be especially careful about bringing their politics to work. Employees may feel obligated to agree with management, so managers must be respectful of all views and careful about sharing their own. In this way, managers can also set an example of how employees should show respect regarding political views. Belden and lobbying Lobbying laws regulate communication between businesses and lawmakers that is intended to shape public policy. Belden follows all such laws. If you come in contact with government officials, know how lobbying laws apply to you. Never attempt to influence a government official to take any unlawful action on Belden’s behalf.

Anti-bribery and anti-corruption Our promise We do business ethically, without bribery or corruption. We succeed because of the value we create for our customers, not by seeking inappropriate advantages. Our reasons Bribery and corruption damage markets and diminish public trust. They also put our reputation and our business at risk. In most places around the world, bribery and corruption can carry severe penalties, including jail time. By following all anti-bribery and anti-corruption laws, wherever we do business, we shield Belden and ourselves from risk and win on the merits. Our actions We avoid bribery and corruption when we: • Never offer anything of value to a government official to win a business advantage • Recognize when a potential bribe is being offered or requested • Never offer or accept bribes or kickbacks • Keep honest and complete records of all payments • Never ask, encourage or allow a third party to make a payment we would not make ourselves • Know and follow all applicable laws and regulations, including the U.S. Foreign Corrupt Practices Act (FCPA), wherever we do business • Report any concerns about possible bribery or corruption to a manager, Human Resources or the Compliance Team, or use our ethics and compliance Hotline Our policy in practice Q One of our consultants has submitted an invoice that lists some vague cash payments for “government fees.” Should I question this invoice? A Yes, you should. This notation could indicate a facilitation payment, which we do not pay. Ask the consultant for supporting details and receipts for this and any other cash payment. If the consultant cannot provide them or you suspect a bribe, share your concerns right away with a manager, Human Resources or the Compliance Team, or use our ethics and compliance Hotline. Find out more Global Anti-Corruption Policy Bribes, kickbacks and unfair advantages Bribes can take many forms, but all are illegal. Examples include, but are not limited to: • Cash or cash equivalents • Lavish gifts or entertainment • Stock gifts or opportunities • Special discounts that are not part of an authorized marketing program • Charitable or political contributions • Unfair advantages for a government official or their family • Payment of lavish travel expenses Anything of value can be exchanged to secure a business advantage. If that is the expectation, then the exchange is a bribe. A kickback is money paid to reward someone for facilitating a transaction or some other outcome. For example, a contractor may pay a government official some portion of a government contract if that official helps the contractor secure that contract. A facilitation payment, or “grease” payment, is anything of value given to expedite a routine process. For example, a business may pay a customs official to get its goods over the border more quickly than others. Belden prohibits facilitation payments regardless of local law or historical business practice.

Insider trading Our promise We follow insider trading laws and protect material, nonpublic information from disclosure. We never use inside information for our own personal gain. Our reasons As part of our employment at Belden, we may become aware of nonpublic information that could be of interest to investors. Such information could be about Belden or one of our business partners. Using this “inside” information to buy or sell securi- ties is illegal, as is sharing it with others. To protect the integrity of financial markets, and our business, we never share material, nonpublic information. Our actions We avoid insider trading when we: • Never buy or sell shares in Belden or any other publicly traded company while in possession of inside information • Never discuss material, nonpublic information with anyone outside Belden, including family and friends • Never provide inside information to investors who intend to act on it, also known as “tipping” • Only share inside information with other employees on a need-to-know basis • Never spread false information or otherwise attempt to influence financial markets unethically • Raise questions or concerns with a manager or the Compliance Team if we are ever unsure about what constitutes material, nonpublic information What is inside information? Material, nonpublic information, also known as inside information, can come in many forms. Examples include: • Marketing strategies • Changes in leadership • Potential business deals • Customers or business partners • Potential mergers or acquisitions • Impending legal action or investigations Any significant information that is not known to the public that could affect financial markets should be kept secure. Our policy in practice Q I am aware of some inside information about one of our customers — a potential acquisi- tion. But I have not traded based on it. The customer has now sent out a press release announcing the acquisition. May I buy securi- ties in this company now? A It depends. Now that the information has been released to the public, whether through a press release, government filing or some other official communication, you may use it to buy or sell securities under insider trading laws. You may, however, want to consider the ethical implications of investing in securities of a customer. Depending on the size of the investment, it could create a conflict of interest for you in future dealings with that customer.

International trade laws Our promise As a global company, we follow all international trade laws that apply to our business. We are a responsible, ethical player in the global economy. Our reasons Doing business around the world is complex, and a variety of laws apply that regulate how we conduct imports and exports. As we continue to grow and create value for our customers, we must understand and comply with these laws to avoid illegal or inappropriate deals. Our actions We conduct international trade responsibly when we: • Know and follow the laws and regulations that affect our business, everywhere we do business, and follow Belden’s review and approval processes • Remain informed about updates and changes to international trade laws and regulations • Conduct screening to ensure we comply with all regulations regarding prohibited, denied and sanctioned parties, and ensure that our third parties do not do business with them • Classify all imports and proac- tively categorize controlled exports to ensure compliance with any restrictions Laws in multiple countries If a transaction involves more than one country, multiple laws may apply.

Boycotts and sanctioned countries Our promise As a U.S.-based multinational company, Belden complies with U.S. and international boycott and sanctions lists. We never do business with nations or other entities subject to sanctions or comply with prohibited boycotts. Our reasons Around the world, countries use boycotts to protest the policies or actions of other countries. As a U.S.-based company, Belden cannot participate in these boycotts unless they are supported by the U.S. government and the governments of our relevant subsidiaries. We are careful to follow the law to ensure ethical international trade and partnerships. Our actions We comply with sanctions and anti-boycott laws when we: • Never participate in boycotts prohibited by the U.S. government • Screen our customers, third parties and vendors against the U.S. denied parties and sanctions lists, as well as lists from the European Union, UN and other countries • Ensure that third parties we do business with remain in compliance with U.S., EU and UN boycott and sanctions lists • Contact the Compliance Team if we ever receive a request to comply with a foreign boycott • Familiarize ourselves with what a boycott request can look like • Follow all policies, laws and regulations related to boycotts and sanctions • Raise any questions or concerns about boycotts or sanctions with a manager, Human Resources or the Compliance Team, or use our ethics and compliance Hotline Know the laws Anti-boycott laws are designed to keep U.S. companies from being used to enforce other countries’ policies, especially when they conflict with U.S. policy. These laws prohibit any participation in a boycott, such as the Arab League boycott of Israel, or discrimination based on factors like race, religion, sex, national origin or nationality. They also prohibit sharing boycott-related information or making deals that contain boycott terms or conditions. Violations of these laws can be serious, including civil and criminal penalties.

What activities can be restricted by sanctions? Knowing what activities can be restricted is just as important as knowing which countries are sanc- tioned. Activities that are restricted for a sanctioned country include: • Asset transfers • Doing business • Payments • Services • Technology exports • Travel When are sanctions used? Sanctions can be used to respond to dangerous or unlawful activities in other countries. The U.S. and other governments may apply sanctions to countries that: • Sponsor terrorism • Proliferate weapons • Traffick narcotics • Use forced or child labor • Violate human rights Our policy in practice Q I noticed something in a new contract with a supplier that sounds like potential boycott language. It says that “invoices must have a certificate of origin stating that goods are not of Israeli origin.” What should I do? A Contact the Compliance Team immediately to address this language. It may be possible to amend the contract and negotiate change, but the Compliance Team must be notified so we can take proper action.
