1st Source (SRCE) Q3 2026 earnings review
1st Source speeds up lending, while problem loans drop
1st Source, the Indiana-based community and specialty lender, sped up loan growth and cut problem loans at the same time. Profit per share rose 19% from a year ago to $2.03 as flat operating costs and a low credit provision amplified an 8% rise in tax-equivalent net interest income. Chief executive Andrea Short also pointed to a wider net interest margin after the bank sold low-yielding bonds at a $4 million loss to buy higher-yielding replacements.
| Tax-equivalent net interest income | $95.7M +7.7% from a year ago |
|---|---|
| End-of-period loans and leases | $7.34B +5.4% from a year ago |
| Diluted profit per share | $2.03 +18.7% from a year ago |
| Nonperforming assets to loans | 0.81% down from 1.01% last quarter |
⚖️ Verdict: 🟢 Bullish
The story got better because loan growth rebounded and problem assets dropped after four quarters near 1% of the book. End-of-period loans grew 5% from a year ago, up from 2% in June, while nonperforming assets fell by nearly a fifth. One caution: deposits barely grew, so deposit costs ticked up and the bank used more short-term borrowings to fund its new loans.
The question now is whether 1st Source can keep expanding its interest income as it laps last year's margin jump. Either solar and equipment loan growth carries interest income, or rising deposit costs and a tougher fourth-quarter comparison compress growth toward low single digits. Fourth-quarter deposit rates and net interest margin will tell.
🐂 Bull Case
Loan Growth Rebounded Led by Renewable Energy
1st Source lends through community branches in Indiana and Michigan and through nationwide specialty divisions covering solar projects, aircraft, trucks, and construction gear. Year-on-year loan growth had slowed to 1.7% last quarter, which threatened to cap future interest income. In the third quarter, total loans and leases at period-end rose by $121.1 million to $7.34 billion, lifting growth from a year ago back to 5.4% by our math.
- Renewable energy loans: $797.9 million, up 32.2% from a year ago by our math
- Commercial and agricultural loans: $855.4 million, up 12.7% from a year ago by our math
- Construction equipment loans: $1.28 billion, up 6.0% from a year ago by our math
- Aircraft loans: $1.10 billion, up 2.7% from last quarter by our math
This rebound matters because a bank cannot grow interest income forever on margin expansion alone. Solar lending added $56.8 million during the quarter, and aircraft and heavy-duty truck balances also grew from the second quarter after shrinking earlier in the year.
What to watch: unfunded loan commitments in the third-quarter filing. If unused credit lines rose alongside loan balances, the bank is refilling its lending pipeline rather than just drawing down old commitments.
Bond Swap Lifted the Net Interest Margin
Net interest margin—the profit spread between what the bank earns on loans and bonds and what it pays on deposits and debt—had stalled near 4.24% for two quarters. In the third quarter, the tax-equivalent net interest margin climbed 4 basis points from last quarter and 19 basis points from a year ago to 4.28%. The gain was cleaner than it looked because interest recoveries added zero basis points, down from 3 basis points last quarter.
1st Source helped its spread through a "repositioning of available-for-sale securities" during the quarter. The lender sold about $68 million of bonds yielding 1.83% at a $3.82 million pre-tax loss and bought replacements yielding 5.10%. That swap lifted the average yield on taxable bonds by 8 basis points from last quarter to 3.40%, which offset a 4-basis-point dip in loan yields to 6.52%.
What to watch: taxable investment security yields in the fourth quarter. A full quarter of the 5.10% replacement bonds will show how much extra spread the swap delivers.
Flat Overhead Pushed Efficiency Below 46%
Banks measure cost control with the efficiency ratio, which shows noninterest operating expenses as a share of net revenue. 1st Source lowered its GAAP efficiency ratio to 45.91% from 46.57% last quarter and 49.50% a year ago. Total net revenue grew 8.7% from a year ago to $120.3 million by our math, while noninterest expense rose just 0.8% to $55.2 million even with a $1.0 million foundation donation.
Employee salaries and benefits—the bank's largest overhead line—fell by 1.9 percentage points of revenue from a year ago to 27.2% by our math, because lower employee group insurance claims held pay and benefit growth to 1.7%. Excluding bond losses, partnership gains, and equipment lease depreciation, the efficiency ratio still improved by 3.0 percentage points from a year ago to 46.19%.
What to watch: salaries and employee benefits in the fourth quarter. If medical claims return to normal levels, overhead growth will move closer to revenue growth.
Problem Loans Dropped 19% From Last Quarter
"Strong credit quality continued during the quarter with low net charge-offs, a lower provision for credit losses, and a reduction in nonperforming assets," chief executive Andrea Short said. Nonperforming assets—loans behind on payments plus repossessed collateral—had hovered near 1.0% of total loans for four straight quarters after problems surfaced in auto rental and specialty trailer accounts.
In the third quarter, nonperforming assets fell 18.7% from June to $59.4 million, or 0.81% of total loans and leases. Nonaccrual loans dropped by $12.7 million to $56.9 million, net loan charge-offs were just $0.33 million (0.02% of average loans), and the credit loss provision fell to $0.90 million from $1.54 million last quarter because special attention loans declined.
What to watch: nonperforming assets as a percentage of loans in the fourth quarter. A second quarter below 0.85% would show that the specialty finance cleanup is durable.
🐻 Bear Case
Auto and Operating Lease Demand Kept Shrinking
While solar and commercial lending grew, 1st Source's vehicle fleet financing and equipment leasing businesses continued to contract. Auto and light truck loans—which finance rental agencies and commercial fleets—fell another 1.3% from last quarter and 11.6% from a year ago to $817.9 million by our math. Consumer loans also shrank 12.9% from a year ago to $106.7 million.
The company also noted "reduced equipment rental income as demand for operating leases continued to decline". Equipment rental fees fell 34.8% from a year ago to $0.45 million, and equipment owned under operating leases dropped 36.8% to $4.8 million. Meanwhile, the bank sold $3.03 million of renewable energy tax equity investments, cutting noncontrolling interests to $30.9 million from $42.8 million in June.
What to watch: auto and light truck loan balances in the fourth quarter. Continued contraction there forces renewable energy and construction lending to carry all the growth.
Deposit Growth Lags Loans and Laps Hard Margin Base
Short highlighted that year-to-date average deposits excluding brokered funds grew 3.50% from a year ago. However, total deposits have barely budged because the bank spent the past year paying off $223.8 million of average brokered deposits. Total period-end deposits rose just 0.8% from a year ago to $7.47 billion, while total loans grew 5.4%, pushing the loan-to-deposit ratio up to 98.3% from 94.0% a year ago by our math.
- Average interest-bearing deposit cost: 2.38%, up 2 basis points from last quarter
- End-of-period short-term borrowings: $233.6 million, up from $199.5 million in June
- Average brokered deposits: $320.6 million, up $19.5 million from last quarter
Because core deposit inflows did not cover the $121.1 million loan expansion, 1st Source leaned on short-term borrowings and brokered funds, and deposit funding costs stopped falling. Furthermore, fourth-quarter tax-equivalent net interest income must lap a 4.29% margin from a year ago that included 14 basis points of one-time interest recoveries.
What to watch: interest-bearing deposit costs in the fourth quarter. If funding costs keep creeping higher to fund loan growth, net interest margin expansion will stall.
Risks this quarter didn't answer
Four standing credit and interest-rate risks cannot be checked until 1st Source files its full third-quarter Form 10-Q report with detailed footnote tables.
- Auto and light truck troubled loans: the release does not show how much of the $12.7 million nonaccrual drop came from the $43.0 million of nonaccrual auto loans or the $16.0 million of past-due modified loans reported in June.
- Aircraft reserve coverage and foreign exposure: the release does not update the $9.5 million of aircraft nonaccruals that carried zero loss allowance in June or the $305 million of exposure to borrowers in Mexico and Brazil.
- Agricultural and small-business borrower grades: special attention loans fell in total, but the credit risk grade table by loan category only appears in the quarterly filing.
- Interest-rate cut sensitivity: the 12-month net interest income simulation for a 100-basis-point rate drop (-1.20% as of June) is disclosed in the filing's market risk section.
👓 Other Themes
Payments Hub Launch for Business Clients
Short announced the launch of the Payments Hub platform for Treasury Services commercial clients during the third quarter. The software "modernizes and simplifies payment operations for single, electronic payments by bringing payment activities into a centralized platform". It combines standard ACH, FedNow, Real-Time Payments, and Instant Payments, and uses automated routing that "chooses the best payment choice balancing speed and costs".
💲 Other KPIs
Regulatory capital grew faster than risk-weighted assets again, lifting the Common Equity Tier 1 ratio by 46 basis points from June and 77 basis points from a year ago. 1st Source bought back zero shares for a second straight quarter after spending $23.35 million in the first quarter, leaving capital well above regulatory minimums.
Net worth per share excluding goodwill and intangibles rose 8.8% from $47.17 a year ago and 0.7% from $50.93 in June. Retained profit of $49.5 million easily covered the $0.45 dividend, though accumulated unrealized losses on the bond portfolio widened to $76.1 million from $46.5 million in June and capped the quarterly book value gain.
Weighted average diluted shares fell 1.6% from 24.47 million a year ago because the bank repurchased 338,356 shares in the first quarter of 2026 and 105,381 shares in the third quarter of 2025. With buybacks paused across both the second and third quarters, the share count barely moved from 24.07 million in June.
🔮 Guidance
Unchanged from last quarter's rate and up 12.5% from a year ago. The board approved a $0.45 per share cash dividend payable November 13, matching the $0.45 declared in July and up five cents from the $0.40 declared in October 2025. 1st Source does not issue revenue, margin, or profit plans.
❓ Key Questions
Which borrowers drove the $12.7 million drop in nonaccrual loans?
Nonaccrual loans fell 18% from June to $56.9 million. Investors need to know whether the bank resolved the troubled auto rental and aircraft accounts flagged last quarter, or if those balances remain on nonaccrual while smaller loans paid off.
Did unfunded credit commitments grow alongside the loan book?
End-of-period loans rose by $121 million in Q3, but the bank also booked a $0.23 million credit provision recovery on unfunded commitments after a $0.44 million recovery in Q2. That suggests unused credit lines may still be shrinking as borrowers draw them down.
Why did accumulated other comprehensive losses jump by $29.6 million?
Accumulated other comprehensive losses widened to $76.1 million at September 30 from $46.5 million at June 30, even as the bank realized $3.82 million of bond losses in income. Meanwhile, the difference between bond amortized cost and fair value widened by $37.6 million.
What caused the $23.4 million drop in tax-equity noncontrolling interests?
1st Source sold $3.03 million of renewable energy tax equity investments during the quarter, and balance-sheet noncontrolling interests fell to $30.9 million from $42.8 million in June and $55.0 million a year ago. Management has not said if it is scaling back tax-equity partnerships.
