Introduction Why do we have a Code? At Erie Insurance (“ERIE”) we believe in doing the right thing as stated in our Founding Purpose: “To provide Policyholders with as near perfect protection, as near perfect service as is humanly possible and to do so at the lowest possible cost�” We value ethical business conduct, accountability, respectful treatment and teamwork� We have a Code of Conduct (“Code”) because it provides a roadmap to help us act not only in compliance with laws and regulations, but also in the spirit of our purpose and values� Our Code helps us to clearly understand how to deliver on our promise to do the right thing� How does our Code apply to me? All those who work for ERIE have a responsibility to understand and follow our Code� Those who interact with ERIE or do work on behalf of ERIE are expected to uphold the values stated in our Code� Our Code applies to all Employees, including officers, and the Board of Directors� Everyone associated with ERIE has an obligation to demonstrate ethical behavior that is consistent with our Code� This includes our Agents, contractors, vendors and others with whom we do business� Our Code does not address every legal or ethical situation, but it helps guide us by supporting our good judgment when we have questions� When we have more specific questions about laws or policies, we can consult additional resources� These resources include: • Employee Handbook • Privacy & Information Security Handbook • Company policies, standards, and manuals available on the company intranet • Online compliance courses 2 “The ERIE is Above all in SERVICE®” – H.O.

Messages from ERIE Our commitment to being Above all in SERVICE is one we take seriously in all aspects of our business� How we uphold that promise matters, and our Code of Conduct serves as a guidepost for doing so in the right ways� Our Code provides the ethical and professional standards for how we do business� It offers clear direction for making decisions and taking actions that are legal, fair and aligned with our purpose and core values� Being Above all in SERVICE, practicing the Golden Rule and sharing the ERIE Family Spirit aren’t just words; they guide everything we do and are key to our success� - Tim NeCastro, President & CEO When H�O� Hirt called it our purpose to provide Policyholders “with as near perfect protection as possible,” he was thinking about the protection that an insurance policy offers individuals and families� But along with “near perfect” protection and service, we also have a duty to be “near perfect” in how we handle decisions and actions that have legal, ethical or professional consequences� Our Code is one way we equip our Employees, Agents, contractors and vendors with the information and resources they need to meet this very important commitment� - Tom Hagen, Chairman of the Board When you face an ethical decision in business, Founder H�O� Hirt’s guidance that “simple common sense, mixed with just plain decency” still rings true� It’s possible you will face a situation where your choices have ethical or legal consequences and the right choice may not seem simple or clear� ERIE’s Compliance Department is here not only to help establish and maintain an environment of compliance and ethics, but to also provide guidance when those choices are not clear� Many other areas of the company play a role in protecting ERIE and our reputation, including Human Resources, Internal Audit, Law and Public Relations� But most important are leaders and Employees like you� Take time to read and understand our Code of Conduct, which reflects what ERIE considers to be legal and ethical behavior� When you’re unsure how to handle a particular situation, understand there are resources available to you� Ask questions� Speak up� And know you can always reach out to me or anyone else in the Compliance Department for further guidance� - Debra Mack, Vice President, Compliance & Ethics 3

4 Our Employees What are my responsibilities under our Code? We are all responsible to “be above all” when it comes to our Code� This means reading our Code, taking time to understand it and asking questions if they arise� Depending on your role at ERIE, you may have different responsibilities under our Code� For example: Employee Responsibilities • Comply with all laws, rules, regulations and court orders� • Know and follow our Code and company policies� • Conduct business truthfully and fairly� • Demonstrate professional behavior at all times� • Exhibit responsible financial management� • Never use a business relationship or company asset for personal gain� • Ask questions� Use the Four Pillars of Ethical Decision Making on the next page to guide you when you are unsure of a situation� • Report actual or suspected violations of our Code or company policies� • Notify your leader and your Employee Relations Consultant (ERC) or HR Business Partner (HRBP) if you are charged with or convicted of a misdemeanor or a felony� Refer to ERIE’s Employee Improprieties Policy for more information� Leader Responsibilities • Lead by example� • Demonstrate a commitment to comply with all laws, rules, regulations and court orders� • Establish and maintain procedures in your work area that are consistent with our Code� • Listen to Employees’ ethical concerns and take action to report these concerns� • Explain the options to Employees on how to report concerns and encourage them to do so� • Guide Employees through the Four Pillars of Ethical Decision Making described in the next section� • Never influence an Employee to behave or act in a way that is not consistent with our Code or company policies� • Establish and follow controls in your area that protect company assets� • Protect Employees from retaliation for reporting concerns by following the Anti-Retaliation Policy� • Demonstrate accountability and responsibility� • Notify your ERC or HRBP if you or an Employee who reports to you becomes aware of, are charged with, or are convicted of a misdemeanor or felony� Refer to ERIE’s Employee Improprieties Policy for more information� If an Employee in the insurance industry is convicted of a felony, federal law requires felonies to be reported to certain regulatory entities.

Ethical Decision Making: Four Pillars When you are faced with situations that are confusing and perhaps do not feel “right,” consider these questions: • Is this action legal? • Is this action ethical? • Is this action in line with our Code and company policies? • Is this action upholding ERIE’s reputation? If you answered “no” to any of these questions: STOP and report the situation to any of the following resources: • Your leader or any ERIE leader • The Compliance Department • Your ERC or HRBP • Any of the Key Contacts at the end of our Code • ERIE Ethicsline

6 Conflicts of Interest A conflict of interest arises when our personal interests interfere, or even appear to interfere, with the Company’s interests� We all have a responsibility to protect ERIE and preserve our reputation for fairness and professionalism by avoiding conflicts of interest and disclosing anything that could appear to be a conflict� While having a conflict of interest is not necessarily a violation of our Code, a failure to disclose a potential conflict is always a violation� Did you know? A conflict can occur on or off the job� For example, a conflict could occur during the course of a second job, an outside activity, a financial investment or endeavor, or any interest that could influence your work and work-related decisions� A conflict of interest can also come from the actions of family members, if their actions or involvements could affect your business decisions� Review our Conflict of Interest and Outside Employment Policy for more information� Be Above All • Understand how to identify a conflict of interest� • Update your conflicts of interest form if something changes� • Avoid interests, activities or relationships that interfere with ERIE Customers' and/or shareholders’ best interests or with your ability to be fair and unbiased� • Never work for a competitor while you are an ERIE Employee� • Never process or service your own policy or claim, or the policy or claim of a family member or friend� • Review the conflicts of interest form document for further guidance� • Discuss any potential conflicts of interest with your leader or Compliance if you are unsure or need guidance� Gifts & Entertainment At ERIE, we should always use good judgment and only give or receive gifts and entertainment when we know that doing so will not compromise our ability to make objective business decisions� ERIE’s Gifts and Entertainment Policy provides guidance for us to follow� Remember that if a reasonable observer could question the particular gift or entertainment, even if it is acceptable per our policy, you should pause and seek advice from Compliance before accepting it� Be Above All • Be mindful that any gifts or entertainment given or received from business contacts should be aligned with our Gift and Entertainment Policy� See the policy job aid for more guidance� • Avoid situations that could reflect poorly on ERIE, such as giving or receiving inappropriate gifts or forms of entertainment� • Be sensitive to third party gift policies and do not offer anything that might violate those policies� Gifts of cash or cash equivalents, such as gift cards or gift certificates are never acceptable.
