First Business (FBIZ) Q1 2026 earnings review
C&I Lending Powers Double-Digit Growth Machine
First Business Financial Services executed its growth playbook flawlessly in Q1 2026, blowing past its 10% annual targets with a 15% annualized surge in loans and an 18% annualized jump in core deposits. EPS grew 9% YoY to $1.44, supported by a 15.8% expansion in non-interest income. Higher-yielding Commercial & Industrial (C&I) lending was the undisputed star, generating two-thirds of the loan growth. However, expenses are running hot—pushing the efficiency ratio above 61%—and a large non-performing CRE loan from last quarter remains largely unresolved.
🐂 Bull Case
The higher-yielding C&I portfolio grew at a blistering 26.5% annualized rate. This favorable mix shift defends the net interest margin against deposit cost pressures.
Core deposits grew 18.4% annualized, vastly outpacing loan growth. The bank is successfully capturing operating accounts, reducing reliance on expensive wholesale funding.
🐻 Bear Case
The efficiency ratio worsened to 61.14% from 56.61% in Q4, moving further away from management's <60% target, driven by a 10.7% YoY spike in compensation expenses.
Non-performing assets (NPAs) remain elevated at 0.94% of total assets compared to 0.61% a year ago, primarily due to a $20.4M single-client CRE downgrade from Q4 that is only partially resolved.
⚖️ Verdict: 🟢
Bullish. FBIZ is delivering on its 'double-digit growth mandate' with high-quality core deposit funding and highly profitable C&I loan demand. If they can rein in expense growth in the back half of the year, the earnings trajectory is highly compelling.
Key Themes
C&I Lending Segment Taking the Lead
Accelerating. The C&I portfolio expanded by $84.4 million in Q1 (+26.5% annualized), accounting for 67% of total loan growth. This shift toward Asset-Based Lending and niche C&I products is a critical driver for margin defense, as C&I yields significantly outpace CRE.
Core Deposits Eliminating Wholesale Need
Accelerating. Core deposits jumped $123.1 million in the quarter. This relationship-driven influx allowed the bank to improve its funding mix, directly supporting the 14.9% annualized loan growth without excessively tapping FHLB advances or brokered CDs.
Private Wealth & Treasury Fees Expanding
Stable. Non-interest income jumped 15.8% YoY to $8.8 million. This was anchored by consistent, annuity-like growth in Private Wealth fees (+11% YoY to $3.9M) and a 25.8% surge in deposit service charges, proving the value of the bank's treasury management platform.
Efficiency Ratio Moving the Wrong Way
Reversing. Management consistently touts 'disciplined risk management' and positive operating leverage, but the data tells a different Q1 story. Operating expenses jumped 13.3% QoQ to $27.1 million, outpacing the 4.9% sequential revenue growth. The efficiency ratio spiked to 61.14%, directly contradicting the strategic goal of driving it below 60%.
Elevated NPAs Require Execution
Stable. The ratio of NPAs to Total Assets dipped slightly QoQ to 0.94% (down from 1.07%), but this was solely due to a small $3.4 million partial sale of the massive single-client CRE downgrade from Q4 2025. With $40.5 million in NPAs still on the books, resolution timeline and final execution carry distinct risks.
Technology Infrastructure Upgrades
Accelerating. Computer software expenses jumped 19.8% YoY to $1.9 million, and data processing rose 17.4% YoY to $1.3 million. The bank cited a change in its credit card vendor and core provider costs to support growth initiatives, indicating a required technology investment phase to sustain their client experience edge.
Macro Uncertainty Clouding Forecasts
Stable. The bank continues to note that borrower caution persists due to inflation, wage pressures, and geopolitical instability. While not currently stopping loan growth, any broad economic downturn could rapidly expose vulnerabilities in the rapidly expanding C&I and CRE portfolios.
Other KPIs
Stable. Up slightly from 3.53% in Q4 2025. The Q1 figure was reduced by 5 basis points due to fewer interest-earning days (adjusted NIM 3.61%). The bank is successfully passing on rates: the yield on earning assets declined, but deposit costs declined even faster, preserving the spread.
Accelerating. Up from $1.85 million in Q4 2025 and $2.66 million in Q1 2025. The higher provision is largely a mechanical result of the robust loan growth achieved during the quarter, combined with $2.3 million in net charge-offs.
Guidance
Decelerating. Management maintained their 10% annual growth target. Given the massive ~15-18% annualized pace achieved in Q1, hitting exactly 10% for the full year implies a moderation in origination pace for the remaining three quarters.
Accelerating. The stated range anticipates a slight sequential improvement from the reported 3.56% in Q1, assuming day-count normalization and continued success in rotating the portfolio into higher-yielding C&I assets.
Stable. This guides to a slight uptick from the 15.2% recorded in Q1, largely dependent on the timing of tax credit partnerships and stock compensation vesting.
Key Questions
Expense Control Re-Alignment
Compensation and software expenses drove the efficiency ratio over 61%. What specific levers will management pull in the back half of the year to bend the expense curve back down toward the sub-60% strategic target?
Remaining CRE NPA Resolution
Following the $3.4 million partial sale at par, what is the realistic timeline and expected loss severity (if any) for the remainder of the $20.4 million troubled CRE relationship downgraded in Q4?
Late-Quarter C&I Surge Sustainability
Management noted that two-thirds of the massive C&I loan growth occurred late in March. Was this a pull-forward of Q2 pipeline deals, or does it signal a sustainably higher run-rate for corporate borrowing demand?
