The key risks to First Business Financial Services (symbol: FBIZ) are:

1. Adverse Economic Conditions and Interest Rate Fluctuations: First Business Financial Services' profitability is significantly influenced by the overall economic environment, including factors like inflation, economic downturns, labor shortages, and wage pressures, which can negatively impact credit quality, revenue, and business operations. Fluctuations in market interest rates directly affect the bank's net interest income by altering the spread between interest earned on loans and interest paid on deposits.
2. Credit Risk and Loan Defaults: The company faces the risk of increased defaults by borrowers and other delinquencies, which directly impacts the quality and performance of its loan portfolio. Maintaining high credit quality in its loan portfolio is crucial for stable revenue. An instance of increased nonperforming assets tied to a single credit in the transportation and logistics sector was specifically noted, although the company has taken steps to mitigate future exposure in that niche.
3. Regulatory and Compliance Risks: As a financial institution, First Business Financial Services is subject to extensive legislative and regulatory requirements, including changes in tax laws, that can impact its operations and financial performance. The ongoing volatility within the banking sector may also lead to new legislation, regulations, or policy changes, potentially increasing government oversight and supervision. Additionally, the proportion of uninsured deposit account balances may expose the bank to enhanced liquidity risk, and it could face increases in FDIC insurance assessments. The company also faces risks related to fraud, including client and system failures or breaches of network security.
