Cullen/Frost (CFR) Q1 2026 earnings review
Expansion Strategy Pays Off as Margins Expand
Cullen/Frost delivered a remarkably clean quarter, driving EPS up 15% YoY to $2.65 and proving that its long-term Texas branch expansion strategy is bearing fruit. While many banks continue to battle margin compression, Frost expanded its Net Interest Margin to 3.74% as the cost of interest-bearing liabilities fell 40 basis points YoY. The Board's confidence was signaled by a 3% dividend hike and $70 million in share repurchases. However, sequentially shrinking deposits and a spike in fraud losses are points to monitor as the bank scales its footprint.
🐂 Bull Case
Net Interest Margin expanded to 3.74%, up from 3.60% a year ago. The bank is successfully managing deposit betas downward as the macro rate environment normalizes.
The Houston, Dallas, and Austin organic expansion has now accumulated $2.6 billion in loans and $3.2 billion in deposits, transitioning from an expense drag to an earnings contributor.
🐻 Bear Case
Average deposits declined 2.6% sequentially to $42.2 billion. If loan growth (5.9% YoY) continues to outpace deposit gathering, funding costs could eventually face upward pressure.
Non-interest expense rose 5.1% YoY, driven by salary increases, rising cloud services costs, and notably, a $2.4M spike in payment system fraud losses.
⚖️ Verdict: 🟢
Bullish. The bank is executing perfectly on its core strategic initiative (Texas organic expansion) while simultaneously expanding margins and returning capital to shareholders.
Key Themes
Funding Advantage Drives Margin Expansion
In a macro environment where many banks struggle to lower deposit costs, Frost's liability management is a massive driver. The average cost of total interest-bearing liabilities dropped sharply to 1.72% from 2.12% a year ago. Because asset yields only declined slightly (from 4.99% to 4.88%), the net interest spread widened from 2.87% to 3.16%.
Organic Expansion Strategy Maturing
With the opening of the Arboretum location, Frost reached 205 branches, increasing its footprint by 50% since late 2018. Management noted these expansion markets have accumulated $2.6 billion in loans and $3.2 billion in deposits. This validates the strategic pivot away from M&A toward organic, de novo growth in major Texas metros.
Wealth & Fee Income Surging
Non-interest income provided a strong tailwind, growing 9.9% overall. Trust and investment management fees grew 11.7% to $48.0M, benefiting from higher market values. Service charges on deposits grew 12.4% to $32.2M, driven by billable treasury management services and account growth, proving the value of the expanding customer base.
Deposit Growth Decelerating
While loans grew a healthy 5.9% YoY, average deposits only grew 1.4% YoY and actually shrank 2.6% ($1.1 billion) sequentially from 25Q4. While the loan-to-deposit ratio remains highly conservative, this divergence means the bank is funding new loan growth out of existing liquidity rather than new deposit inflows.
Fraud Losses and Cloud Costs Pressure Expenses
Contradicting the otherwise pristine operational narrative, "Other non-interest expense" jumped 10.4% YoY. Management specifically cited a $2.4M increase in deposit fraud losses related to various payment systems. Additionally, technology expenses rose 3.9%, driven by a $1.8M increase in cloud services. While manageable, escalating cyber and tech costs are a structural headwind.
Sequential Tick in Non-Accruals
Credit quality remains exceptional by historical standards, but non-accrual loans ticked up sequentially to $72.4 million from $70.5 million in 25Q4. It remains lower than the $83.5 million from a year ago, but the sequential rise bears monitoring to ensure it is not the start of a new trend.
Other KPIs
Stable. Matches Q3 2025 levels and is roughly half of the $13.1 million recorded in Q1 2025. Annualized net charge-offs fell to just 0.11% of average loans, highlighting excellent underwriting discipline despite rapid loan portfolio growth.
Accelerating. The board raised the quarterly dividend by 3% to $1.03 per share. Concurrently, the company repurchased 507,753 shares for $70.0 million, leaving $230 million on the current authorization. Total risk-based capital sits at a robust 15.89%.
Guidance
Management previously stated in 2025 that the Houston, Dallas, and Austin branch expansion program would cross the breakeven threshold and become accretive to EPS in 2026. The 15.2% YoY growth in diluted EPS this quarter strongly suggests this goal is currently being achieved.
Key Questions
Deposit Growth Strategy
With average deposits shrinking 2.6% sequentially, what specific deposit-gathering initiatives are being deployed across the new expansion branches to reverse this trend?
Fraud Mitigation
You cited a $2.4M increase in deposit fraud losses related to payment systems. What specific vectors were exploited, and what technology investments are being made to plug these vulnerabilities?
Capital Deployment Priorities
With CET1 at 14.07% and $230 million remaining on the buyback authorization, how aggressive will management be with repurchases if the stock price remains elevated, or will capital be entirely diverted to organic loan growth?
