Committed to our communities, our local families and businesses, our employees and our shareholders living our values every day CITIZENS & NORTHERN CORPORATION 2015 Annual Highlights  

living our values every day On the cover Inside this report In March of 2015 Citizens & Northern Bank launched its Giving Back, Giving Together Community Involvement Initiative. By Giving Together as employees of Citizens & Northern Bank we were able to raise more than $50,000 in support of 22 local food pantries in our communities. In addition, 6,583 food items were collected during quarterly food drives in our offices and our employees volunteered at food pantries 111 times. Throughout this year's Annual Highlights we'll share remarks from our customers, employees and community organizations. We wanted to know why they bank at, partner with and work for C&N and if they feel we live our values. Their answers were so gratifying we wanted to share them with you. Also throughout the year, C&N contributed thousands of dollars to other local non-profit organizations. This dedication to the communities we serve is just a part of how the C&N team lives our values - every day. "Everything showed an amazing amount of teamwork" This year, Citizens & Northern Bank took huge strides in fighting hunger in their communities. After meeting with a few staff members, I realized that I was working with an engaged, enthusiastic and committed group of individuals, that would make any endeavor a success! We were able to bring more awareness to the hunger issues in our communities through the campaign they ran throughout their service territory. We also were incredibly grateful for their food and financial donations. Citizens & Northern Bank certainly lives up to their values. Everything that was done this year for the Central Pennsylvania Food Bank showed an amazing amount of teamwork.

"Banking with C&N gives me peace of mind" My many years of just personal banking at C&N have been great. Now several years of my association with the Trust* department (Marla and Brian) have been excellent as well. They are the team that I have come to know and respect all the while recognizing there are many others backing them who I don't know. Banking with C&N gives me peace of mind. I knew I had trustworthy individuals working with me, advising me, yet allowing my input to be considered. I have never had a moment of doubt that they had my best welfare in mind and have been treated with true respect each time we meet. Kay Hoag 50-year customer "C&N helped me reach my goals for my business" I have found exemplary conduct and attitude among all the loan officers at the Athens branch. Ginger in particular is a joy to do business with and follows through in a very timely fashion with everything she says. I do business with C&N bank because it is comprised of local people who understand, can sympathize with, and will work to help you resolve your problems and meet your goals. Opening a user friendly and affordable business account and establishing a business relationship through which I could secure a business loan in the future helped me reach my goals for my business.

living our values every day A Message from Our President J. Bradley Scovill President and CEO 2015 was a year of alignment and progress at C&N. Your Company produced very solid financial results in an environment where the continuing themes of modest economic growth, persistently low interest rates, and increasing regulation were complemented by major upheaval in the energy markets, a political/budget impasse in the state of Pennsylvania, and the early stages of a very unusual presidential election cycle. While all of these issues affect us in some way, the impact of advancing technology on delivery of financial services and new types of competition is providing opportunities and challenges for our bank and industry. Citizens & Northern Bank's Net income for the year was $16.5 million compared to $17.1 million in 2014. Earnings per share were $1.35 and $1.38 for the same periods. Return on average equity for 2015 was 8.72% and return on average assets was 1.32%, very strong measures relative to our peers in the industry. Earnings per share fell by 2% in 2015 as compared to 2014. While net interest income declined by 2.4%, strong loan growth provided some support and we prepaid a substantial portion of high cost borrowings during the year that will enhance the margin going forward. The provision for loan losses increased nearly 80% in order to support loan growth, although overall credit quality remains strong. Non margin revenues were essentially flat in most categories, but remain very strong relative to peer performance. Core noninterest expenses decreased by 3.5% primarily due to reductions in salaries and employee benefits. Finally, we booked securities gains of $2.9 million that were substantially offset by losses of $2.6 million resulting from the previously mentioned prepayment of high cost borrowings. On the balance sheet, total assets declined by 1.5% due to a 3.3% reduction in deposits. There was a significant shift in our asset mix as the growth in loans was funded by a reduction in the volume of investment securities. While these changes create a more profitable mix in the near term, we plan to fund loan growth with a renewed emphasis on deposit gathering moving forward. Capital remains very strong and provides us with the capacity to support our plans for growth and expansion. Capital remains very strong and provides us with the capacity to support our plans for growth and expansion. CZNC stock ended the year at $21.00, an increase of 1.6% for the year. CZNC stock ended the year at $21.00 an increase of 1.6% for the year, and dividends per share were $1.04 producing a yield of 4.95% on the December 31, 2015 market price. Additionally, we made progress on the 5% share repurchase plan that was announced in July 2014. At year-end, a total of 435,200 of the 622,500 shares approved under the plan had been repurchased at an average price of $19.34 per share. We will continue to focus on efforts that position the stock to be fairly valued for our current and future investors.

living our values every day A Message from Our President Continued from Page 2 "Your Bank for a Lifetime" is the tagline we use in branding C&N and it reflects the mission of our company which is "Creating Value Through Lifelong Relationships". We have a combination of banking and wealth management skills that are unique in our market and that position us to deliver on this promise. Our team of experienced professionals use our scale and strong capital base to provide you with sophisticated solutions to your financial needs and grow the organization. While in recent years our growth has stalled, 2015 was a year of progress as we focused our efforts on re-energizing and aligning the C&N Team to drive profitable growth. Throughout the year, we built and maintained momentum in expanding customer relationships as evidenced by loan growth totaling $74 million, which included increases in all loan categories. Each new loan involves a customer relationship that can be enhanced by the value delivered through our team of professional bankers and wealth managers. To reinforce this focus, our entire Team is engaged in implementing a sales/relationship management system that aligns all business activities to deliver value for our customers. We believe that this model will improve our ability to drive revenue growth across all business lines. Inherent in this alignment is investment in technology that contributes to an improved customer experience and enhanced productivity. We completed work on a new website that was rolled out late January 2016. This site now serves as the foundation for enhancing on-line services moving forward that will simplify and provide greater access to our customers. This access will connect with in-branch, call center, and mobile delivery channels as we coordinate our "high touch" experience with the "high tech" tools that our customers increasingly demand. To be successful, we are making substantial investments in equipping our people with the skills required to bring value to each customer relationship. The environment and industry remain very dynamic and requires that each member of the Team is developing their capabilities. The pace of change continues to accelerate and is reflected by a renewed sense of urgency at C&N. We have a very engaged staff that is excited by the opportunities that are open to the Team moving forward. Finally, we remain committed to the values that serve as the foundation for building relationships both inside C&N and with our communities, customers, and shareholders. Teamwork, Excellence, Respect, Responsibility and Accountability, Integrity, Client-focus and Having Fun, are part of the daily conversation at C&N. The results of our "Giving Back, Giving Together" initiative for 2015 to support the local food banks throughout our markets were outstanding. Not only because we collectively raised over $50,000 to help meet the need, but we also established many relationships throughout our communities that will endure. We will be working to support volunteer emergency services in a similar fashion during 2016. As you read this Annual Review, note how our Mission and Values come together to create valued relationships with our customers as we work to become their "Bank for a Lifetime". We made great progress during 2015 with this mission, helping our customers, and positioning C&N to pursue profitable growth in a very dynamic industry. We will continue to invest and align everything we do to create value for customers and our Team, and are confident in our capacity to create long term value for our shareholders. We thank our shareholders for your investment and ongoing support. "Your Bank for a Lifetime" is the tagline we use in branding C&N and it reflects the mission of our company which is "Creating Value Through Lifelong Relationships". We have a combination of banking and wealth management skills that are unique in our market and that positions us to deliver on this promise." teamwork excellence respect responsibility and accountability integrity client-focus fun [3]

Battin Corporate Secretary "C&N captured our vision and mission" When Endless Mountain Music Festival was first founded in 2005, we opened our checking account with C&N Bank. It was that initial partnership that helped the festival grow from a 12 member orchestra to a 60 member orchestra that we are proud to showcase each summer. Partnering with C&N was easy because they captured the festival's vision and mission to enrich the cultural, educational and economic life of the region. The festival was able to grow from six concerts in 2006 to sixteen concerts in sixteen days by 2015. This is a direct result of the financial impact that Citizens & Northern Bank has given to EMMF over the past ten years. Because of C&N's financial support, we are able to strengthen our educational outreach programs and perform full orchestra concerts. We were able to impact over 2,000 students and senior citizens through educational programs.

We eventually transferred our personal banking to C&N due to how comfortable we felt with the bank and the attention to detail we noticed with every question and transaction we had involving anybody at C&N. We now work with Linda Gordner for our current home loan. Linda has been wonderful answering all of our questions promptly and continuing our confidence in C&N.

Scott EVP and Director of Trust Division “I like to create a true win-win relationship” I didn't choose C&N Bank for any one particular reason; it was really a combination of several reasons. Price was certainly important, but definitely not more important than delivery, service and quality. When I do business I like to create a true win-win relationship. It's all but impossible to create a win-win relationship if you're focused solely on price. C&N is definitely competitive. They have to be, but they shine delivering the whole package. A few years ago I had an opportunity to start a business that I was quite confident could be a great investment. The catch was that it was going to take significant capital and I needed it quickly. My C&N relationship managers didn't hold back. They asked the tough questions that needed to be asked. I value their input. The bottom line was we worked together to manage the risk and get me the capital I needed; another win-win for me and C&N Bank.

"I chose C&N because of its services; I stay because of its people" Gimmicks do not draw my attention; service does. My banking needs are numerous, specific, and sometimes complicated. When I evaluated C&N Bank nearly a decade ago toward its potential to meet my banking needs, here is what I found: Convenient locations. Check. Weekend hours. Check. Drive-through banking. Check. Widely available ATM services. Check. Online banking. Check. Electronic monthly statements. Check. Fast, efficient loan-application processing. Check. Friendly, capable people. Check, check. More important, though, are the congenial and helpful C&N Bank employees whom I have met at my local C&N branch. Ginger, Mel, Sheila, Beth, and all of the other capable and efficient C&N Bank employees with whom I have interacted over the years are also knowledgeable, reliable, and supportive. We even share an occasional story and a laugh. I chose C&N Bank because of its services; I stay because of its people. Theodore F.

living our values every day "My passion is doing what's right for people" One of the primary motivating factors that prompted me to pursue financial advising as a career was my strong belief in giving unbiased financial advice regardless of whether it generated maximum revenue to my employer or me. As a young man I had seen my family adversely affected by a particular life insurance agent, and I was pretty sure her advice was strictly driven by how much money she would make. In my tenure at C&N, I have never once had anyone attempt to quell that passion to do what is right for people. In fact, that passion is shared by everyone. For my team "superior service" means getting to know our clients, understanding what is truly important to them, and helping them put a plan together to accomplish those very personal desires. Larry Alderson, Regional Manager of Financial Services Delivery - Sayre "We all strive to work as a team" Every time I come to work I am a part of a team. I have two branches that depend on me to do my job so that they can do theirs. That is one of the nice things about working for Citizens & Northern Bank, we all strive to work as a team. We all have different strengths which we can call upon to do the best for our clients and make us successful. Penny Barr, Regional Community Office Manager Port Allegany “I am proud to be a member of C&N every day” I enjoy the people that I work with, the opportunities that we have for personal career development and the teamwork involved in helping to grow the bank and be successful. I also enjoy helping small businesses grow their companies and being a trusted advisor to assist them with exceeding their goals. The bank has a great group of employees who are devoted to making C&N the Only Bank You Need by providing superior customer service and helping our clients out in any way possible.
