Cullen/Frost Bankers, Inc.'s mission is 'to be the superior financial services provider in the markets we serve by delivering consistent, long – term value to shareholders, clients, and communities.'

The bank aims to grow deposits, loans, and relationships by opening nearby branches, deepening local relationships, and broadening fee businesses across its Texas footprint.

Takeaway: Cullen/Frost Bank Company growth strategy centers on organic market densification, relationship lending, and fee-income expansion rather than M&A.

Market Footprint Densification

Cullen/Frost is executing a Frost Bank strategic expansion focused on sub-1-mile customer proximity in fast-growing ZIP codes across Houston and Dallas – Fort Worth. Management opened 53 new branches across those metros during 2024-2025 and added 10 more locations in 2025 alone, aiming to increase wallet share among over 400,000 retail relationships. This branch-and-market expansion supports higher branch-level deposit and fee capture and underpins its Cullen/Frost branch optimization and consolidation strategy in lower-return areas.

Loan Portfolio Expansion

The bank targets sustainable loan growth driven by relationship-based commercial and consumer lending. Guidance calls for 10-12% annual loan growth through 2026 as an aspirational target; for fiscal 2026 management projects average loan growth of 5-7%. The focus is on commercial real estate in Texas, middle – market commercial & industrial (C&I) loans, and owner – occupied CRE tied to the densified branch footprint. Forecasting Cullen/Frost loan growth through 2026 should use 2025 year-end loan balances as the base.

Deposit Capture & Capital Allocation

Deposit growth is expected to scale with the branch roll – out; expansion deposits have already exceeded $3,000,000,000. Management projects average deposit growth of 2-3% for 2026. The Cullen/Frost capital allocation plan maintains a conservative CET1 posture, prioritizing organic reinvestment into branches and relationship banking while preserving capacity for regular dividends and buybacks consistent with historical payout ratios.

Revenue Diversification & Wealth Restructuring

To reduce reliance on net interest income, Cullen/Frost is expanding mortgage originations, insurance, and advisory services across its client base. The bank restructured its wealth management business in 2025 to drive organic fee growth, cross-selling to existing retail relationships and targeting higher-margin trust and investment management mandates. This ties into Frost Bank digital transformation initiatives to improve lead conversion and product penetration.

Execution Risks & Mitigants

Key risks: slower-than-expected loan pull-through, branch ROI lag, Texas CRE cycle softness, and funding cost pressure. Mitigants: tight underwriting, sub-1-mile branch placement to lift deposit economics, diversified product push (mortgage, insurance, wealth), and maintaining liquidity buffers. Use the bank's 2025 balance sheet and cash – flow metrics when modeling downside scenarios.

Implications for Investors

Expect moderate balance-sheet growth and gradual NII expansion if management hits 5-7% loan growth and 2-3% deposit growth in 2026; fee income should rise with mortgage, insurance, and wealth initiatives.

Company's vision is 'to be the most trusted financial partner for customers and communities we serve.'

Cullen/Frost Bank Company aims to build a digitally enabled, capital-strong regional bank that deepens commercial relationships while scaling branches and digital services across Texas and adjacent markets.

Direct takeaway: Cullen/Frost is investing in digital transformation, cloud core modernization, relationship infrastructure, and capital preservation to execute its Cullen/Frost Bank Company growth strategy and Frost Bank strategic expansion.

Digital transformation and AI

In 2025 Cullen/Frost allocated approximately 15 percent of non-interest expense to technology and digital transformation, targeting Frost Bank digital transformation initiatives and Frost Bank digital banking investments and roadmap. Investments include production AI and machine learning models for predictive credit modeling and fraud detection; management reports a 25 percent improvement in fraud detection accuracy over an 18-month window. These capabilities support faster product launches, improved credit decisioning, and lower operational losses-key to Cullen/Frost earnings growth guidance and forecasts.

Core modernization

The bank is migrating core banking systems to cloud-based infrastructure to shorten time-to-market for new product iterations and improve resilience. Cloud migration reduces batch processing windows and enables continuous delivery pipelines, which shortens product development cycles from quarters to weeks. This underpins efforts such as Cullen/Frost branch optimization and consolidation strategy and enables fintech partnerships for strategic growth.

Relationship infrastructure for commercial clients

Cullen/Frost is expanding treasury management, ACH, and real-time payments to deepen engagement with middle-market commercial clients-central to Frost Bank commercial lending growth strategy and How Cullen/Frost plans to grow in Texas markets. Upgraded APIs and integrated cash management portals aim to increase fee income and reduce commercial client churn; pilot clients report faster reconciliations and same-day settlement on select flows.

Capital fortress and deployment cadence

Growth is underpinned by a strong capital base: Common Equity Tier 1 (CET1) ratio stood at 14.06 percent as of December 31, 2025, giving room to absorb branch ramp-up costs that typically take 18-24 months to mature. That buffer supports the Cullen/Frost capital allocation plan, dividend policy and capital return strategy, and selective M&A activity aligned with Cullen/Frost M&A strategy without stressing regulatory ratios.

Operational agility and branch strategy

Operational investments focus on workflow automation, centralized operations hubs, and lean branch operating models to improve efficiency ratio and deposit growth and retention tactics. Branch market expansion pairs with local commercial bankers and digital onboarding to compete with national banks in Texas. Management states new branch payback assumptions assume full revenue maturation in 18-24 months.

Risk, controls, and measurable KPIs

Risk capabilities include AI-driven fraud controls, credit model governance (model risk management), and enhanced cyber defenses. KPIs tracked include time-to-market for products, fraud false-positive reduction, commercial deposit stickiness, and return on technology investment (ROTI). These measures align with forecasting Cullen/Frost loan growth through 2026 and Cullen/Frost risk management during rapid expansion.

Cullen/Frost Bank Company promotes prudent, relationship-led banking: prioritize credit quality, local decision-making, conservative capital management, and disciplined branch growth to preserve franchise strength and low-cost deposit advantages.

Conservative Credit Discipline

Leaders stress underwriting and local credit approval to limit losses; this shows up in higher reserves and stricter CRE underwriting standards.

Relationship-Driven Deposit Gathering

The bank emphasizes local deposit relationships and branch presence to protect a low-cost funding base versus national competitors.

Measured Physical Expansion

Growth via targeted branch and market expansion is deliberate, balancing growth with an efficiency ratio target in the low 50s.

Capital Conservatism and Payout Discipline

Focus on strong CET1 ratios and steady dividends guides capital allocation and constrains aggressive M&A without clear returns.

How Cullen/Frost's Operating Principles Map to Risk

The principles are sensible but not immune to concentrated risk: heavy Texas exposure and CRE concentration create failure modes that disciplined culture alone may not offset.

• CRE concentration: roughly 47 percent of total loans historically, with office loans near 11 percent of total loans
• Customer/execution focus: relationship deposit model helps retention but faces national-bank competition in Texas
• Culture/decision-making: local credit authority supports quick responses but amplifies regional-cycle sensitivity
• Distinctiveness: conservative capital and localism are clear, yet geographic concentration makes strategies less diversified

The primary threats that could break Cullen/Frost Bank Company's growth strategy cluster into four vectors: CRE exposure, deposit competition, regional macro sensitivity, and execution cost overruns. CRE concentration remains the most tangible single risk: historically CRE has been about 47 percent of total loans and office exposure about 11 percent, per the bank's 2025 disclosures and investor presentation. Sustained office vacancy increases or price declines in Texas would raise non-performing loans (NPLs) and force mark-to-market valuation losses, pressuring reserves and ROA.

Deposit competition from national banks-JPMorgan Chase and Bank of America expanding in Texas-threatens low-cost funding. If deposit beta rises and the company must pay higher rates to retain balances, net interest margin (NIM) could compress. In 2025, average deposits growth slowed versus prior years; a shift to higher-cost retail or wholesale funding would reduce net interest income and EPS.

Regional macro sensitivity is structural: nearly all loans, deposits, and fee income are Texas-centric. A local recession, energy-sector shock, or regulatory change in Texas would have outsized impact on asset quality and revenue. For example, if Texas commercial payrolls decline materially, CRE cash flows tied to office and retail could deteriorate simultaneously across the portfolio.

Execution costs from scaling branches and technology are a fourth vector. Management projects funding high-single-digit non-interest expense growth through 2026 while targeting an efficiency ratio in the low 50s. Missing that cost discipline-if the efficiency ratio drifts toward the mid-50s and non-interest expenses grow faster-would dilute promised EPS accretion from expansion and could force reduced dividend flexibility or slower capital returns.

Specific break scenarios with quantifiable effects:

• Sharp CRE valuation shock: a 20 percent writedown across office and other CRE could increase loan-loss provisions by several hundred million dollars and cut 2025-2026 EPS by a mid-single-digit percentage range.
• Deposit repricing: a 50-100 basis-point rise in deposit costs without offsetting asset yields could compress NIM by 10-25 bps, reducing net interest income and trimming projected ROE.
• Regional recession: a Texas GDP contraction of >2 percent year-over-year could raise NPL ratios materially above 1.0-1.5 percent baseline, forcing higher provisions and loan charge-offs.
• Execution overspend: non-interest expense running >7-8 percent annually through 2026 while revenue growth lags could move the efficiency ratio above 55 percent, reversing EPS leverage.

Risk mitigants management can deploy include accelerating CRE portfolio repricing and workouts, diversifying loan mix beyond CRE and Texas markets, strengthening digital deposit channels to offset branch-competitive pressure, and enforcing strict expense targets tied to branch productivity.

Cullen/Frost Bankers, Inc.'s stated mission and values show up in choices that favor measured, client-focused growth: management funds targeted branch expansions while investing in cloud AI to augment relationship banking, and capital allocation prioritizes organic loan growth over costly external funding.

Product and Service Alignment with Relationship Banking

Loan products and treasury services emphasize personalized underwriting and local relationship managers, while digital tools are built to speed advisors rather than replace them.

Targeted Market Expansion and Branch Siting

Branch openings focus on Texas growth corridors and selective adjacent markets; expansion locations already added 0.12 dollars of EPS accretion in recent quarters, signaling early payoff from the rollout.

Operations: Cloud-First, Relationship-Forward

Operational investments prioritize cloud-based AI for credit decisioning and client insights, enabling faster execution while preserving high-touch branch processes.

Culture: Local Decision Rights and Tech Enablement

Hiring favors experienced commercial bankers and data specialists; leadership rewards local origination success and disciplined credit discipline.

Customer Experience: High-Touch, Faster Service

Clients see quicker turnaround on loans and richer advisor dashboards; branches remain primary acquisition and relationship hubs complemented by digital outreach.

Strongest Real-World Example: EPS Accretion from New Markets

The clearest proof is the expansion locations contributing 0.12 dollars of EPS recently, supported by a conservative balance sheet with a 50.3 percent loan-to-deposit ratio that leaves sizeable room to grow the loan book organically.

If further context is helpful: the setup-branch-led growth plus cloud AI and a low loan-to-deposit ratio-points to disciplined acceleration into 2025-2026, contingent on Texas office market stability.

How the Principles Show Up in Strategic Choices

Cullen/Frost Bankers, Inc.'s principles-relationship focus, prudent capital use, and selective tech adoption-are embedded in actual choices: prioritizing organic loan growth, funding branch expansion from deposits, and adopting cloud AI to speed service without displacing branch roles.

• New relationship lending products emphasize local credit authority and tailored pricing
