Issues of quickly rising interest rates, contracting NIM, tight liquidity, and the fear of looming credit-quality issues are enough to create concern for the industry. Yet, amidst the problems is opportunity for those who are looking for ways to improve their company and add shareholder value. During the third quarter of 2023, Franklin Financial Services Corporation (FFSC) continued its efforts to grow the balance sheet and build profitability through a series of small steps that limit risk in the uncertain economic environment. The company has been successfully building commercial loan balances by developing new customer relationships while maintaining strong credit quality (.01% non-performing assets/assets) and adequate reserves (allowance for credit loss stands at 1.29% of loans). The company has also been rebuilding deposit relationships after experiencing a sharp runoff in the fourth quarter of 2022 (loan-to-deposit ratio was 77% at the end of the third quarter). And though deposit rates are rising, we have been able to maintain a respectable cost of deposits, resulting in a relatively flat NIM. Brokerage and trust assets continue to grow, providing additional fee income for the company. There are areas in which we want to improve, including our efficiency ratio and building other sources of non-interest income. We do this against a backdrop of strong capital and liquidity positions that afford us the opportunity to make improvements to the balance sheet that, while they negatively affect income in the short run, will result in medium- and long-term benefits to the company. F&M TRUST Franklin Financial Services Corporation 3 CEO Comments As we discussed at the end of the second quarter, FFSC is focused on the future.

Outlook for the Remainder of 2023 Deposit balances will moderate due to the tension between rising rates and the bank’s efforts to control interest costs and manage liquidity needs Market pressure on deposit rates and competition for high-quality lending relationships may have an adverse effect on NIM The negative effect of the Accumulated Other Comprehensive Income on book capital should decrease as investments move to maturity (average portfolio life is under 5.5 years) Fee income from the Investment & Trust Services division should continue to grow with the addition of new clients / assets and should only be moderated by the general performance of both the bond and equity markets With increased focus on finding operating efficiencies, both internally and with our external third-party vendors, we expect to see an improved efficiency ratio in 2024 F&M TRUST Franklin Financial Services Corporation 15 Summary The Company continues to be well capitalized and positioned to successfully develop new Commercial and Investment & Trust relationships The bank is positioned to fund future growth Asset quality is good, and the Company is well provisioned for losses should they occur in future quarters due to economic factors The Company is actively working to bring more digitally based products and services to its customers The Company is positioning for future growth and expansion following the completed consolidation and move to a new corporate headquarters and operations center, the addition of Salesforce, the additions to senior leadership, and a new full-service community office in Maryland F&M TRUST Franklin Financial Services Corporation 16
