Byline Bancorp (BY) Q3 2026 earnings review
Byline's lending margin widens, but its problem loans jump 22%
Byline Bancorp, the Chicago commercial bank, grew its net interest income and deposits while its loan book shrank and problem loans increased. Revenue rose 5% from a year ago to $121 million, beating what the bank's own third-quarter plan pointed to as president Alberto Paracchini used new deposits to pay off $269 million of wholesale debt. Higher staff pay offset the revenue gain, so quarterly profit only rose because renewable energy tax credits cut the tax bill.
| Total revenue | $121.0M +4.6% from a year ago |
|---|---|
| Net interest margin | 4.33% +0.05 percentage points from last quarter |
| Loans held for investment | $7.46B -1.1% from last quarter |
| Quarterly dividend outlook | Unchanged $0.14 per share for Q4, +40% from a year ago |
⚖️ Verdict: 🔴 Bearish
The story got worse because the two main risks — stalled lending and credit quality — both moved the wrong way. Loans held for investment fell 1% in the quarter, including a drop in loans Byline originated itself, and non-performing assets jumped 22% to $88 million. The good news: chief executive Roberto Herencia doubled share buybacks and announced the purchase of Illinois State Bancorp to put idle capital to work.
The question now is whether the jump in non-performing loans is a one-off borrower issue or the start of wider stress in the commercial loan book. If one already-flagged loan caused the increase, low credit provisions can hold; if new business loans are souring, credit costs will rise. The detailed loan tables in the upcoming quarterly 10-Q filing will settle it.
🐂 Bull Case
Deposit Growth Funded a $269 Million Debt Paydown
"The third quarter produced record net interest income of $103.7 million and expanded our net interest margin by five basis points to 4.33% in a quarter when funding costs rose across the industry," president Alberto Paracchini said. Net interest margin (NIM) is the spread between what a bank earns on loans and bonds and what it pays on deposits and debt.
Byline grew total deposits by $168.3 million, or 2.1% from last quarter, to $8.04 billion. Because customer deposits rose while the loan book shrank, the Chicago lender cut wholesale borrowings by $268.7 million and lowered its loan-to-deposit ratio to 93.2%. Replacing 2.97% Federal Home Loan Bank debt with deposits lifted the margin, even though average deposit costs ticked up 0.03 percentage points to 1.95% and loan accounting accretion fell by 0.05 points.
What to watch: fourth-quarter net interest income and deposit costs on the conference call. If deposit growth keeps funding the balance sheet without higher rates paid on checking accounts, the margin will hold above 4.30%.
Capital Returns Doubled on a 13.3% Capital Ratio
Byline has been building capital faster than it lends, raising concern that idle equity would weigh on shareholder returns. This quarter chief executive Roberto Herencia said the bank "returned more than $20 million of capital to stockholders through share repurchases and a 16.7% increase in our common dividend to $0.14 per share during the third quarter."
The company bought back 521,980 shares, nearly double the 274,528 shares it repurchased in the second quarter. Total capital returned reached 63.2% of net income, up from 35.9% last quarter, and reduced the diluted share count by 1.8% from a year ago. Even after that payout, Common Equity Tier 1 (CET1, a core measure of a bank's capital strength against its risk-weighted assets) climbed 0.37 percentage points to 13.29%.
What to watch: fourth-quarter share repurchases now that Byline has announced the acquisition of Illinois State Bancorp. A pause in buybacks would show management is saving capital to close the deal.
🐻 Bear Case
Loan Balances Shrank as Payoffs Outpaced New Lending
Byline wants to grow its loan portfolio at a mid-single-digit rate this year, and management previously said the bulk of acquired loan runoff was behind it. Instead, total Assets fell $33.7 million in the third quarter, which the company said was "primarily driven by an $80.9 million decrease in loans and leases held for investment, reflecting loan payoffs and sales that exceeded portfolio growth during the quarter."
- Loans held for investment: $7.46 billion, down 1.1% from last quarter and down 0.6% since year-end by our math
- Originated loans: $7.04 billion, down $32.6 million from last quarter as commercial and industrial balances fell $50.1 million
- Acquired loan portfolio: down $48.3 million from last quarter to $424.6 million by our math
This matters because the contraction was not just old acquired loans paying off; the bank's own originated loan book shrank too. With nine months gone and loans slightly below where they started the year, hitting the full-year growth target is nearly out of reach.
What to watch: management's fourth-quarter loan pipeline commentary on the conference call. A cut to the full-year loan outlook would confirm that customer payoffs and tougher pricing competition are capping balance-sheet growth.
Non-Performing Assets Rose 22% in One Quarter
Last quarter management pointed to favorable credit trends as problem loans stabilized, and this quarter the bank cut its credit loss provision by 5.8% to $6.7 million, citing better collateral indicators and a smaller loan book. Yet non-performing assets — overdue loans no longer accruing interest plus foreclosed property — jumped $15.6 million, or 21.6%, to $87.9 million, which the release said was "primarily attributable to an increase in non-accrual loans and leases."
Even stripping out the $9.7 million portion backed by US government guarantees, non-guaranteed problem assets rose $14.1 million by our math. Non-performing loans climbed from 0.92% of the loan book to 1.14%, the highest level in over a year, while annualized net charge-offs (loans written off as uncollectible) rose from 0.24% to 0.31%. The company also had to add reserves for individually evaluated problem loans.
What to watch: the substandard and delinquent commercial loan tables in the upcoming quarterly 10-Q filing. They will show whether this spike came from one borrower already flagged last quarter or broader stress across business borrowers.
Higher Staff Costs Ended Four Quarters of Efficiency Gains
Byline improved its efficiency ratio — operating costs excluding intangible amortization as a share of revenue, where a lower figure is better — for four straight quarters down to 46.93% in the second quarter. In the third quarter, non-interest expense rose $3.3 million, or 5.9%, to $59.8 million, pushing the efficiency ratio back up by 1.47 percentage points to 48.40%.
Salaries and employee benefits drove the increase, rising $3.4 million to 32.3% of revenue, up 2.0 percentage points from last quarter by our math. Because higher staff pay and legal fees ate up the entire revenue gain, pre-tax pre-provision profit was unchanged at $61.2 million. Net income only grew from last quarter because "the purchase of renewable energy tax credits during the third quarter" cut the tax rate to 23.3%, adding $0.03 per share by our math.
What to watch: fourth-quarter operating expenses against the $59–60 million quarterly target range. A reading above $60 million would show that higher payroll and deal legal fees are lifting the bank's cost base.
Risks this quarter didn't answer
Four standing concerns depend on disclosures in the quarterly 10-Q filing or conference call that do not appear in the earnings release.
- Commercial payments business: unmentioned in the release; client count and deposit balances from the conference call will show if the unit is contributing in 2026.
- Substandard business loan migration: risk-rating and 30–59 day delinquency tables in Note 5 of the 10-Q will show if early-stage credit stress widened.
- Commercial real estate pricing competition: originated commercial real estate loans grew 3.8% to $2.39 billion; call commentary on loan yields will test pricing pressure from large banks.
- Illinois State Bancorp deal terms: purchase price, tangible book value dilution and the earnback period are not in the release and await presentation slides.

Illinois State Bancorp Deal Nears the $10B Threshold
Byline announced the acquisition of Illinois State Bancorp, parent of First Nations Bank and The Bank of Bourbonnais. Chief executive Roberto Herencia said "The transaction expands our market presence, strengthens our core deposit base, and adds talented bankers and long-standing customer relationships." With assets at $9.90 billion, closing the deal will push Byline past the $10 billion mark that triggers federal debit-card fee caps and higher deposit insurance costs.
💲 Other KPIs
Unchanged from last quarter and up 10.8% from a year ago. Pre-tax pre-provision net income — operating profit before credit loss reserves and taxes — equaled 2.45% of average assets, down from 2.49% in Q2, marking a 16th straight quarter above 2.00%.
Down 9.3% from $78.1 million last quarter and down 23.8% from $92.9 million a year ago. Lower Small Business Administration loan sales volume reduced net gains on loan sales by 4.8% from last quarter to $5.8 million, though gains still beat the $5.5 million quarterly target.
Fell 1.4% from $24.48 last quarter after rising in prior quarters, though still up 6.9% from a year ago. Tangible book value per share — net worth per share excluding goodwill and intangibles — dipped because unrealized losses on the bond portfolio widened by $46.4 million and the bank returned $20 million in capital.
🔮 Guidance
Unchanged. The board declared a $0.14 per share quarterly dividend payable in November, matching the third-quarter rate after raising it 16.7% in July and 20.0% in January. At $0.14, the dividend sits 40% above the $0.10 paid a year ago and equals 14.9% of third-quarter profit.
❓ Key Questions
What are the financial terms of the Illinois State deal?
The release announced the acquisition of Illinois State Bancorp but gave no asset size, price, tangible book dilution or closing date. Those numbers determine how much excess capital the deal absorbs and when Byline crosses $10 billion in assets.
Which borrowers drove the $15.6 million jump in non-performing assets?
Non-performing assets rose 21.6% even as the credit provision fell. Investors need to know whether the $20.6 million business loan that was 30–59 days past due last quarter moved to non-accrual, or if new loans soured.
Why is the originated loan book now shrinking too?
Management previously blamed slow loan growth on planned runoff in acquired loans, but originated loans fell $32.6 million in Q3. Did new loan originations slow down, or did payoffs spread to the core commercial book?
What is the fourth-quarter outlook for net interest income and expenses?
Byline provides its quarterly net interest income, fee and expense ranges on the conference call rather than in the release. After Q3 payroll jumped $3.4 million, the Q4 expense plan will show if the cost step-up is permanent.
