 2023 & 2024 Challenges 

 Challenges  Turbulent Economy  The Fed managed to bring down inflation without the economy tumbling into a recession in 2023. Economic, political and global uncertainty will cloud 2024.  

 Challenges  Staffing Struggles  Staffing shortages were experienced by all businesses throughout 2023. FCCB will continue to focus on our “hire to retire” mentality to retain satisfied employees. 

 Challenges  Cybercrime  Our customers continue to be targets of financial crimes and fraud. FCCB is committed to help customers mitigate such risks. 

 Challenges  Regulatory Requirements  There is a lot more coming at banks as an industry. Some bills, like ACRE, help to sustain and grow rural and ag communities, while other bills, like 1071, if passed, will have a negative effect on small businesses. 

 Challenges  Customer Preferences & Digital  Customers expect more convenience and personalization from both digital banking experiences and traditional banking channels.  

 2023 Stewardship 

 Stewardship  Helping the Homeless  As a result of our partnership with the FHLB and their Home4Good Program, 18 organizations will receive $1.4 million in grants to help those who are homeless. 

 Stewardship  Education  In 2023 FCCB donated $345,000 to organizations that support education. 

 Stewardship  Food Insecurity  FCCB donated $25,000 to the Central PA Food Bank in 2023, bringing our total donation to $103,000 in just four years. 

 Stewardship  Fighting Cancer  Our annual Cancer Classic golf tournament raised $20,000 in 2023 for a cumulative total of $301,000. 

 Stewardship  Sustaining Agriculture  In the ag arena, FCCB funds the PA Farm Bureau’s Mobile Ag Lab, supports local 4-H and FFA at community fairs, and grants our annual Ag Scholarships. 

 Happy Retirement  Gene Kosa  Served 23 years on the CZFS & FCCB Boards  Chairman of the Audit Committee  Member of Credit Committee  Strong advocate of the ag industry
