FOR OVER 168 YEARS, supporting the individuals and businesses that comprise our community has been AT THE HEART of all we do. Although we’ve grown from our beginnings as a local bank on Gettysburg’s Lincoln Square, to the diversified financial services company we are today, our commitment to providing relationship-based services and reinvesting in our communities has never wavered, and is as strong today as it has ever been. In 2024, ACNB Corporation continued to deliver on our promise, by SUPPORTING OUR COMMUNITIES through our services, investments and dedicated staff, all while continuing to PROVIDE STRONG FINANCIAL RESULTS to our shareholders and execute our strategic plan.

REPORT TO SHAREHOLDERS 4 5 ACNB CORPORATION 2024 ANNUAL REVIEW Traditions Bancorp, Inc. Acquisition A major focus and strategic accomplishment for the Corporation in 2024 was the July announcement of the entry into a definitive agreement to acquire Traditions Bancorp, Inc., and its subsidiary Traditions Bank. This strategic acquisition, which closed effective February 1, 2025, represents two exceptional community banks coming together to become an even stronger organization that is prepared to serve its customers into the future. By acquiring Traditions Bank, ACNB Bank has expanded its community banking branch office network by 6 offices throughout York and Lancaster Counties in Pennsylvania, which will do business as “Traditions Bank, A Division of ACNB Bank.” ACNB Bank has also retained Traditions Bank’s first-class mortgage loan operation and team, which will do business throughout ACNB Bank’s footprint as “Traditions Mortgage, A Division of ACNB Bank,” under the leadership of Traditions Mortgage President Teresa L. Gregory. As a combined organization, ACNB Bank has an increased scale, efficiency, and product set to serve our customers. We are confident that together the combined company can deliver more to our communities and shareholders than either company could have on its own. At the close of the acquisition, we welcomed three former Traditions Directors, Eugene J. Draganosky, Elizabeth F. Carson, and John M. Polli, to the Boards of Directors of ACNB Corporation and ACNB Bank. Mr. Draganosky has nearly 40 years of banking experience, and is the former CEO and Chair of the Board of Traditions Bancorp, Inc. and Traditions Bank, having held those roles since 2017 and 2023, respectively. Ms. Carson joined the Traditions Bank Board in 2015, after over 30 years of banking experience in a variety of leadership roles with community and regional banks, and completing her career as a senior vice president with M&T Bank. Mr. Polli, President & CEO of Reliance Student Transportation, was a member of the Traditions Bank Board of Directors since its founding in 2002, and has nearly 40 years of diverse business expertise, from serving as a public accountant to owning, managing, and advising businesses in the transportation, real estate, and insurance industries. We are confident that Mr. Draganosky, Ms. Carson, and Mr. Polli will enhance and add value to ACNB’s Boards of Directors, and will provide us with valuable insight into the York and Lancaster markets and customers. In addition, Michael Kochenour, one of the founders of Traditions Bank, and original CEO and Chairman of its Board, has joined ACNB Corporation as a Director emeritus. Mr. Kochenour’s support of the transaction has been integral to this acquisition coming to fruition, and his continued input and contributions in this role will likewise greatly assist in furthering its success. Many employees from both organizations have worked diligently throughout 2024 and into 2025 to evaluate and complete this acquisition and plan for the integration of our systems and people, and we would be remiss if we did not publicly acknowledge how immensely grateful we are for their efforts. We are truly fortunate to have a skilled and dedicated group of leaders and banking professionals within our company that are committed to delivering a successful integration and customer experience. 2024 Financial Performance Our continued focus on community banking principles has produced another year of solid financial performance and continued strong returns for our shareholders. Net income for the year ended December 31, 2024 was $31.8 million, or $3.73 per common share. This represents a modest increase of $158 thousand, or 0.5%, over net income for the year ended December 31, 2023. Notably, the financial results for the year ended December 31, 2024 were impacted by $2.0 million in merger-related expenses incurred as a result of the Corporation’s strategic acquisition of Traditions Bancorp, Inc. The strong earnings in 2024 were primarily a function of the Corporation’s relatively high net interest margin of 3.79% for the year, driven by solid loan growth and effective control of deposit and funding costs. We also saw meaningful increases in non-interest income compared to the prior year due primarily to increases in revenues from sales of insurance, wealth management fee income, and gain on sales of residential mortgage loans. The Corporation’s return on average equity of 10.94% and return on average assets of 1.31% for 2024 reflect strong underlying performance across our businesses. We view the financial results of 2024 positively, as the Corporation, like many banks and financial holding companies, continued to navigate an uncertain interest rate environment and changing monetary policy in 2024. We are proud that our organization accomplished these strong operating results while continuing to grow and invest in our lines of business, working towards achieving our strategic initiatives, and exercising disciplined risk management and credit practices. Shareholder Dividends and Equity In 2024, ACNB Corporation furthered its long history of paying a sustainable and growing dividend to its shareholders. In 2024, the Corporation paid aggregate dividends of approximately $10.7 million to its shareholders, or $1.26 per share of common stock, with the quarterly dividend increasing from $0.30 per share to $0.32 per share starting in the second quarter of 2024. The amount of dividends paid per share in 2024 increased 10.52% over the $1.14 in dividends paid per share in 2023, and 18.87% over the $1.06 per share paid in 2022. We consider the Corporation’s dividend payout, at a ratio of 33.6% of earnings in 2024, to be a means of rewarding our shareholders for their continued investment in the Corporation, while also allowing sufficient earnings to be retained by the Corporation for continued growth and reinvestment into the business. At year-end 2024, total stockholders’ equity was $303.3 million. As compared to $277.5 million at year-end 2023, this is an increase of 9.3%, due to earnings retained as capital in 2024 and new shares of common stock issued from our dividend reinvestment plan. Tangible book value increased to $29.51 per share as of year-end 2024, an 11.6% increase over the $26.44 as of year-end 2023. ACNB Bank ACNB Bank, the banking subsidiary, is the primary driver of revenues and profit at ACNB Corporation. Although the Bank’s roots extend back to when it was established more than 168 years ago, the Bank’s core business model of reinvesting its depositors’ dollars into loans to individuals and businesses in our local communities is fundamentally the same now as it was when it was founded. Today, ACNB Bank serves its local communities with banking and wealth management services via a network of 33 community banking offices and one loan office located in southcentral Pennsylvania and northern Maryland. In addition, ACNB Bank continues to invest in new technology to better serve both our current and future customers, through an array of digital and mobile tools. In 2024, the Bank focused on executing fundamental community banking principles, which led to notable loan growth and superior asset quality. Total loans outstanding were $1.68 billion at December 31, 2024, an increase of $54.9 million, or 3.4%, from year-end 2023. This increase was driven primarily by growth of $70.8 million, or 7.9%, in the commercial real estate loan portfolio in our core Pennsylvania and Maryland market areas in 2024. Despite the intense competition in the Corporation’s market areas, management continues to focus on asset quality and disciplined underwriting standards in the loan origination process. Asset quality continues to be a key strength of the Bank, with non-performing loans to total loans at 0.40% at December 31, 2024, and net charge-offs to average loans outstanding at a remarkably low level of 0.02%. It has always been the Bank’s business model to reinvest depositors’ dollars in loans to others in our communities. This endeavor occurs every business day at ACNB Bank with the continued goal of increasing loan growth in local markets, while maintaining a reasonable funding base by offering competitive deposit products and services. The Bank continues to benefit from a stable, low-cost funding source of customer deposits, contributing to its attractive net interest margin. The employees of ACNB Bank also demonstrate their commitment to the communities in which they live and work through volunteerism and community involvement. In 2024, the Bank’s employees supported 251 community organizations by collectively contributing more than 2,500 volunteer hours in the Bank’s market areas. The community banking offices served as collection points for toys, school supplies, and food items to benefit local organizations. Additionally, 31 Bank leaders gave back to important causes in 2024 by serving as Board and/ or committee members to 40 charitable organizations within the Bank’s footprint. The Bank matched our employees’ support of local organizations with their time by making financial contributions to 197 community organizations and non-profits in 2024. 6 ACNB CORPORATION Wealth Management ACNB Bank’s Wealth Management Division is composed of Trust & Investment Services staff and Wealth Advisors, with the goal of working in tandem to offer a full range of options for client investment planning and portfolio management. Under the Bank’s trust powers, traditional fiduciary, investment and related services are provided to clients. Via a third-party relationship, ACNB Bank offers retail brokerage services under the brand of ACNB Wealth Advisors. With assets under management and administration of $683.8 million at December 31, 2024, the Wealth Management Division attained revenues from fiduciary, investment management, and brokerage activities of $4.2 million for the year, an increase of 16% over the prior year. Over the last 2 years, from the end of 2022 to the end of 2024, the Wealth Management Division has grown its assets under management and administration by over $165 million, representing a 31.8% increase. This significant growth is a testament to the Wealth Management Division’s client-centered approach combined with favorable market performance during that period. 2024 was also the first full year for Trust & Investments Services staff on its new trust accounting platform that was implemented in the fall of 2023. This new system has expanded the efficiencies and capabilities of the Trust & Investment Services team to better serve its clients and deliver a modern platform that is expected in conjunction with its personalized, relationship- based service. ACNB Insurance Services, Inc. 2024 was also a successful year for ACNB Insurance Services, Inc., the full-service insurance agency that has been wholly-owned by ACNB Corporation since 2005. Revenues from this subsidiary’s commissions from insurance sales is the most significant source of noninterest income for ACNB Corporation, totaling a record $9.8 million in 2024, a 4.7% increase over the $9.3 million generated in 2023. Net income from the agency in 2024 was $1.1 million, down slightly from a record $1.3 million in 2023, a result of the agency’s efforts to balance profitability with growth for the future through investments in its staff, technology offerings, and community partnerships. As a full-service insurance agency offering a broad range of property, casualty, liability, health, life, and disability insurance to both personal and commercial clients that is licensed to place business in 46 states, ACNB Insurance Services, Inc. adds diversity to ACNB Corporation’s revenue stream by way of stable non-interest income derived from a larger geographic area. The agency is a strategic asset of the Corporation, and reinforces the Corporation’s position in the marketplace as a complete provider of financial services encompassing both banking and insurance. In Closing With a firm foundation built on trust, relationships, and support of the individuals and businesses in our community, we are confident in our ability to grow our company well into the future.
