One of my first looks at the inner workings of C&N was during orientation when a member of the Retirement Services team addressed our class. He spent 2 hours teaching the basics of planning and preparing for retirement, reviewing various retirement plan options, and providing recommendations to those in the room based on their specific ages and goals. He took a complex concept, broke it down, and presented the information in a simple- to-understand way, which led to a high level of engagement from those in attendance. I was impressed by his expertise and the level of care he showed.

Cybersecurity Because money is such an important asset in people’s lives, the threat of criminal attacks against banks has been around since the financial industry was established. This constant threat has not changed despite our currency becoming more digitized through mobile and online banking platforms. As business accessibility moves toward a more virtual atmosphere, it’s important for banks to always stay a few steps ahead of cyber criminals. It is universal throughout the entire financial industry that banks devote a large amount of resources to cybersecurity. Jobs and even entire departments whose primary goal is to neutralize the threat of cyber- attacks exist throughout financial institutions. As criminals find new ways to attempt to breach a bank’s infrastructure, information security jobs become more sophisticated in their efforts. These efforts include educating themselves as well as setting up trainings and providing resources that all employees of their organization are required to complete. It is also common practice for banks to share incidents with other financial institutions to help strengthen the industry as a whole, so that all banks can prepare and minimize disruption if similar cyber-attacks take place. Banks are also subject to some of the most rigorous regulatory requirements in any industry. This means that your bank is required by law to meet a certain level of security or it could face stiff fines and penalties. For instance, the multifactor authentication to access your digital banking has been a requirement for financial institutions to force into their online platforms for several years. These regulations are all done in favor of protecting the customer’s money. Many banks, however, go well beyond the minimum regulatory requirements. Providing customers with information, training and resources on cybersecurity is still the best way to keep criminals at bay. Because education is the first and most important piece of thwarting attacks, there will be no shortage of resources from your bank on how you can help protect your information. Emergency Preparedness Most banks also have stringent internal policies regarding their preparedness for emergencies and disasters. These often involve committees who meet on a regular basis to discuss scenarios that may disrupt their organization’s functions Financial Literacy Month While providing financial education is fundamental to every community bank’s mission, the C&N team takes our responsibility as a trusted financial resource for our communities seriously – it’s how we do business. During the month of April, which is Financial Literacy Month, we extend our efforts in an attempt to reach all of our community members by way of on-site presentations and sharing relevant educational content through a multitude of platforms. April is also Teach Children to Save Month, hosted by the American Banking Association (ABA) Foundation, so we focus our efforts this month on educating children 13 and under. One of the first steps in properly managing your finances from a young age is learning how and why to save money. Throughout this month, C&N is giving away piggy banks to any children who visit a C&N office and share their savings goals with us. We kicked this off with our teammates first and a video showcasing their little ones’ savings aspirations. Spoiler alert: one is saving for a beach house, we think. This month, our teams also connect with local schools and youth groups to present the ABA’s “Teach Children to Save.” Historically, our teams reach an average of 1,200 children each year. Although this program has been presented virtually the last two years, we are excited to present it in person again, along with our saving spokesbug, Sammy Saver (pictured right). In addition to encouraging children to save and hosting presentations, we will also continue using a #FiscalFridays platform on social media to share educational tips and articles every Friday to help parents along their child’s financial education journey.

C&N’s 3-tier delivery model sets the foundation for a sustainable, profitable future for C&N and our stakeholders. Strategic investments in infrastructure, technology and our teammates are designed to deliver an excellent experience and create value for our customers across every delivery channel. Branches & Roots So far this year, our home office in Wellsboro has been completely remodeled and work has begun in our Troy location. Not only will these offices have a more current look and feel to them, but they’ll provide a better environment for our teams to meet clients’ evolving preferences and exceed their expectations. As customers continue to gravitate to digital, self-service channels for routine transactions, the reduction in branch traffic has lessened the need for rows of tellers. Instead, the space has been configured to be more conducive to engaging in more consultative discussions between the customer and C&N expert. In our SouthCentral region, our York office has transitioned from a Loan Production Office to a full-service branch and a new, full-service office in Lancaster is now open for business. In our SouthEast region, the wheels are in motion to relocate the Paoli offices to a more visible and accessible location in Chesterbrook. These strategic moves will position us for long-term growth and continued expansion in these important markets. The full-service Lancaster office opened in October 2021 C&N’s Chesterbrook office will replace our Paoli location this summer. C&N’s Wellsboro office remodel was completed in March of 2022. Work on C&N’s Troy office began this spring. Pictured above is the teller line transition. CZNC $ 24.38 (as of 3/31/2022) | 3

A perfect example of this took place during the COVID-19 pandemic. While the pandemic came as a surprise to the general population, most banks have had a pandemic response plan in place for years. Because of these annual preparedness plans, most financial institutions were able to swiftly put their plan into action and continue to provide their essential service without missing a beat. So, if a disaster does occur, you can rest assured that your bank is prepared to respond in kind. Because US banks are insured, prepared against cyber-attacks and practice for emergencies, uncertain times are exactly when you need your bank the most.
