Risks

• Interest rate risk: Earnings and cash flows are highly sensitive to interest rate fluctuations, which are beyond the company's control and could adversely affect net interest income, loan origination, deposit acquisition, and asset/liability fair values.
• Lending concentration risk: Approximately 80.9% of the loan portfolio consists of commercial and industrial, energy, construction, and commercial real estate mortgage loans, which generally carry higher default risks and are susceptible to economic downturns.
• Allowance for credit losses insufficiency: The determination of the allowance for credit losses involves significant subjectivity and estimates, and changes in economic conditions, inflation, interest rate volatility, or new information could require substantial increases, negatively impacting net income and capital.
• Commercial real estate market conditions: Commercial real estate mortgage loans comprise 47.1% of the loan portfolio and are sensitive to real estate market and economic conditions, with particular concerns regarding the long-term performance of office properties due to remote work trends.
• Volatility risk in crude oil prices: The energy loan portfolio (5.0% of total loans) is exposed to cyclical and volatile oil and gas prices, which could negatively impact borrowers' ability to repay and increase credit losses.
• Liquidity risk: Access to funding sources could be impaired by economic downturns, difficult credit markets, adverse regulatory actions, or negative market/customer perceptions, especially given that approximately 52% of deposits were uninsured at December 31, 2025.
• Unrealized losses in securities portfolio: Significant unrealized losses on available-for-sale securities, while not affecting regulatory capital, could impact liquidity if sales are required or negatively affect market/customer perceptions.
• Operational risks: Reliance on analytical and forecasting models for credit losses and fair value measurements carries risks of inaccuracy, particularly during market stress, due to flawed design, implementation, or human error.
• Failure or circumvention of controls and procedures: Internal controls, including fraud detection and cybersecurity, provide only reasonable assurance, and failures could lead to reputational damage, litigation, regulatory fines, or financial losses.
• New lines of business, products, services, and technological advancements: Efforts to implement new offerings or technologies, including artificial intelligence and cloud technologies, involve substantial risks and may not achieve expected timetables or profitability targets.
• Negative publicity risk: Reputation is vulnerable to negative public opinion arising from actual or alleged conduct, including ESG matters, cyber-attacks, or actions of employees/third parties, potentially affecting customer attraction, employee retention, and regulatory scrutiny.
• Changes in customer behavior: Individual, economic, political, and industry-specific conditions can alter customer borrowing, repayment, investment, and deposit practices, adversely affecting business needs and regulatory compliance.
• Reliance on dividends from subsidiaries: Cullen/Frost's primary liquidity source is dividends from Frost Bank, which are subject to federal and state regulatory limitations.
• Information systems failure, interruption, or breach in security: Reliance on electronic systems for operations and sensitive data storage exposes the company to significant disruption, unauthorized access, theft, misuse, or destruction of data, with increasing risks from cyber-attacks and quantum computing.
• Increasing fraud risk: Exposure to growing sophistication and frequency of fraud (cyber fraud, identity theft, account takeover) can lead to financial losses, increased operational costs, and reputational damage.
• Reliance on external vendors: Dependence on third-party vendors for critical products and services introduces operational, cybersecurity, and information security risks, including performance failures and data breaches.
• Litigation risk pertaining to fiduciary responsibility and intellectual property: Claims related to fiduciary duties or intellectual property infringement could result in significant financial liability, reputational damage, and increased operating expenses.
• Economic conditions in Texas: Success is substantially dependent on the general economic conditions of Texas and specific local markets, making the company vulnerable to regional economic downturns.
• Soundness of other financial institutions and counterparties: Interrelatedness within the financial services industry exposes the company to credit risk from counterparty defaults and increased cyber-attack risks.
• Highly competitive industry and market area: Substantial competition from larger banks, fintechs, and other financial institutions, potentially with fewer regulatory constraints or lower cost structures, could weaken competitive position and profitability.
• Extensive government regulation and supervision: Subject to broad federal and state laws, regulations, and supervisory guidance, which can change unpredictably, increase costs, limit activities, and lead to enforcement actions for non-compliance.
• Repeal of federal prohibitions on interest on demand deposits: Could increase interest expense and decrease net interest margin if the company offers interest on demand deposits to compete.
• Government regulation and oversight relating to data and privacy protection: Extensive laws and regulations require significant resources for compliance and carry potential liability for non-compliance or data breaches.
• Potential adverse effects of a U.S. federal government shutdown: Prolonged shutdowns could disrupt government agencies, impair borrowers' financial capacity, and create financial market volatility.
• Potential acquisitions may disrupt business and dilute shareholder value: Acquisitions involve risks such as unknown liabilities, asset quality issues, business disruption, diversion of management attention, and potential dilution of tangible book value and EPS.
• Acquisitions may be delayed, impeded, or prohibited due to regulatory issues: Regulatory approvals for acquisitions can be delayed or denied based on various factors, including compliance records.
• Stock price volatility: The company's stock price can fluctuate significantly due to various factors, including operating results, analyst recommendations, industry news, and general economic conditions.
• Changes in accounting standards: New or revised accounting standards can materially impact financial statements, potentially requiring retroactive application or cumulative charges.
• Inability to attract and retain skilled people: Competition for talent, especially key personnel, is intense, and unexpected loss of services could adversely impact business due to customer relationships, skills, and industry experience.
• Severe weather, natural disasters, acts of war or terrorism, pandemics, and other adverse external events: Such events could significantly impact business operations, deposit base stability, loan repayment ability, and asset values.
• Climate-related risks: Physical risks from extreme weather events and long-term shifts, as well as transition risks from legislative/regulatory changes and divergent stakeholder views, could negatively impact the company and its customers.

Future Outlook

The Federal Reserve projects the midpoint of the appropriate target range for the federal funds rate to decrease to 3.4% by the end of 2026 and 3.1% by the end of 2027, implying up to a 25 basis point decrease in 2026 and another 25 basis point decrease in 2027. The impact of proposed Federal Reserve changes to permissible interchange fees, which could reduce revenues by approximately 30%, remains uncertain. The extent of future offsets or potential shortfall special assessments related to FDIC deposit insurance is also uncertain. State-level activity in privacy and cybersecurity standards is expected to continue.

Management Comments

• Management believes the recorded amount of the allowance for credit losses on loans is appropriate based upon its best estimate of current expected credit losses within the existing portfolio of loans.
• Management is not aware of any events that are reasonably likely to have a material adverse effect on liquidity, capital resources, or operations.
• Management believes that it is less likely the company will pay interest on commercial demand deposits as rates increase, based on experience during the last interest rate cycle.

Industry Context

StockSavvy.ai notes that Cullen/Frost Bankers operates in a highly competitive financial services industry, facing challenges from larger national and regional banks, as well as rapidly growing financial technology (fintech/wealthtech) firms that may have fewer regulatory constraints and lower cost structures. The potential for new regulations, such as the GENIUS Act establishing a framework for payment stablecoins, could introduce increased competition for traditional bank deposits. The industry is also experiencing increased regulatory and stakeholder focus on climate change and broader ESG matters, which could lead to divergent policies and conflicting requirements. The company's strong capital position and focus on organic growth in Texas markets position it to navigate these competitive and regulatory pressures, though the impact of proposed interchange fee changes and evolving fraud risks remain key industry-wide concerns.

Comparison to Industry Standards

• The company's capital ratios (CET1: 14.06%, Tier 1: 14.50%, Total Capital: 15.95%, Leverage: 8.80%) are significantly above the 'well capitalized' minimums, indicating a strong capital buffer compared to industry benchmarks.
• The return on average assets of 1.24% and return on average common equity of 15.66% in 2025 demonstrate solid profitability within the banking sector.
• The company's strategy of organic growth within Texas markets, augmented by experienced, centralized support, contrasts with larger, more geographically diversified national banks, which may have higher lending limits and broader service offerings.
• The company faces competition from fintechs/wealthtechs, which are often not subject to the same regulatory burdens, potentially allowing them to offer more competitive pricing or innovative products, a trend observed across the broader financial services industry.
• The company's qualitative factor adjustments for credit losses, including overlays for downside scenarios and credit concentrations, reflect a proactive risk management approach in line with best practices for managing complex loan portfolios, particularly in commercial real estate and energy sectors, which are under increased scrutiny across the industry.

Management Changes

Corporate Governance

Legal Proceedings

• The company is subject to various claims and legal actions arising in the ordinary course of business, but management does not expect their ultimate disposition to have a material adverse effect on financial statements.

Related Party Transactions

• Loans granted to certain directors, executive officers, and their affiliates totaled $316.1 million at December 31, 2025.
• Payments for services provided in transactions with certain directors and/or their affiliates totaled $2.1 million in 2025.
• Lease payments to entities controlled by or affiliated with one of the directors totaled $375 thousand in 2025.

Stakeholder Impact

• Shareholders: Benefited from increased net income, diluted EPS, and higher common stock dividends ($3.95 per share in 2025). The new $300.0 million stock repurchase plan indicates potential for further capital returns and mitigation of dilution.
• Employees: The company increased salaries and wages, and employee benefits expense, reflecting investments in human capital. The average tenure of all full-time employees was approximately 9.4 years, and executive officers 30.3 years, suggesting a stable workforce.
• Customers: Benefited from a broad array of commercial and consumer banking services, trust and investment management, insurance, and brokerage. However, potential changes in interchange fees could impact service pricing or offerings. Increased fraud losses may indicate challenges in customer protection.
• Creditors: The company's strong capital ratios and liquidity position enhance its ability to meet debt obligations. Subordinated notes and junior subordinated deferrable interest debentures are part of the capital structure.
• Regulators: The company is subject to extensive federal and state regulation, with ongoing scrutiny on capital levels, liquidity, credit risk, cybersecurity, and consumer protection. Compliance with new accounting standards and regulatory proposals (e.g., interchange fees, resolution planning) is a continuous focus.

Next Steps

• The 2026 Annual Meeting of Shareholders is scheduled for April 29, 2026.
• Frost Bank's initial informational filing for resolution planning was due April 1, 2026, but submission requirements have been suspended by the FDIC pending finalization of rule amendments.
• The Federal Reserve is expected to issue a revised proposal for Basel III Capital Rules in early 2026, though it is not expected to apply to Cullen/Frost Bankers.
• The FinCEN rule extending anti-money laundering obligations to registered investment advisers has a delayed effective date of January 1, 2028.
• The outcome of litigation regarding the Federal Reserve's current interchange rules is pending appeal, which could significantly affect future debit card transaction fees.
• The CFPB is considering revisions to its final rule requiring data availability to consumers, with litigation currently stayed.

Key Dates

Recommendation

The company demonstrated strong financial performance in 2025 with significant increases in net income and diluted EPS, driven by robust net interest income and non-interest income growth. Its capital ratios remain well above regulatory minimums, indicating financial strength and stability. The authorization of a new, larger $300 million stock repurchase plan and a consistent increase in common stock dividends signal management's confidence and commitment to shareholder returns. While non-interest expenses increased and potential regulatory changes to interchange fees pose a future risk, the overall positive financial trajectory, strong balance sheet, and strategic focus on organic growth in the resilient Texas market make Cullen/Frost Bankers an attractive investment.
