NBT Bancorp (NBTB) Q3 2026 earnings review
NBT Bancorp lending spreads widen, but problem loans keep rising
NBT Bancorp, a northeastern community bank, earned record profit on wider lending spreads while its troubled commercial loans kept climbing. Profit per share excluding one-offs rose 6% from a year ago to $1.11 as the lending margin reached 3.78% and retirement-plan and deposit fees grew. Chief executive Scott Kingsley highlighted solid loan growth, yet net loan additions slowed to a quarter of the second quarter's pace.
| Net revenue | $195.0M +4.8% from a year ago |
|---|---|
| Profit per share, excluding one-offs | $1.11 +5.7% from a year ago |
| Net interest margin (FTE) | 3.78% +0.05 percentage points from last quarter |
| Nonperforming loans | $70.0M +35% since December |
⚖️ Verdict: ⚪ Neutral
The story is unchanged because a one-off accounting boost helped the lending margin while commercial credit did not fully heal. Overdue loans fell as promised, but more commercial borrowers stopped paying interest, pushing total problem loans up 7% from last quarter. By our math, merger accounting income supplied four-fifths of the quarterly margin gain, and short-term debt nearly tripled since December to fund the balance sheet.
The question now is whether rising problem loans are a routine post-merger cleanup or the start of broader commercial losses. Optimists point to low loan write-offs and two-times reserve coverage, while skeptics note that problem loans have risen for three straight quarters even as the bank trimmed its loss reserve. Fourth-quarter nonperforming loan balances and the conference call's merger-accounting outlook will settle it.
🐂 Bull Case
Wider Lending Spreads Lifted Profit to a Record
NBT Bancorp, a community bank with 174 branches across seven northeastern states, is earning a wider spread between its loan rates and its deposit costs. "We delivered solid loan growth, grew net interest income and expanded our net interest margin, and continued to maintain strong capital levels," chief executive Scott Kingsley said.
- Net interest margin (lending profit as a share of interest-earning assets, adjusted for tax-exempt income): 3.78%, up 0.05 percentage points from last quarter
- Net interest income: $142.1 million, up 5.5% from a year ago
- Profit per share, excluding one-offs: $1.11, up 5.7% from a year ago
The margin beat the 3.73% floor management set last quarter because loan yields rose 0.05 percentage points to 5.69% while deposit costs dipped to 1.32%. One caution: "a $1.5 million increase in purchase accounting accretion" — an accounting boost from the 2025 Evans Bancorp merger — supplied about 0.04 points of that 0.05-point margin gain by our math.
What to watch: the quarterly merger accounting boost on the conference call. If that boost drops back next quarter, ordinary loan repricing will have to work harder to keep the lending margin at 3.78%.
Fee Businesses Grew Past Last Year's One-Off Gains
NBT runs two fee-based businesses alongside its branches: EPIC, a national retirement plan administrator, and a regional insurance agency. Noninterest income excluding securities gains rose 2.9% from a year ago to $52.9 million. By our math, underlying fee income grew 6.0% once $1.5 million of one-time life-insurance and contract gains from last year's third quarter are stripped out.
Retirement plan fees rose 8.7% from a year ago to $17.3 million on new customers and higher market values, while deposit service charges climbed 15.5% to $5.9 million "reflecting the impact of deposit account pricing initiatives implemented during the quarter". Noninterest expenses excluding prior-year merger costs rose 4.7% from a year ago to $115.2 million: salaries fell 1.3 percentage points of net revenue from last quarter, while other activity-based expenses rose 0.9 points.
What to watch: fourth-quarter operating expenses on the call. Management previously targeted 2.5% to 3% full-year expense growth, and a 4.7% third-quarter pace leaves little room in the fourth quarter.
Taxable Securities Yields Keep Climbing Without Restructuring
While many peer banks sold low-rate bonds at a loss to buy higher-yielding ones, Kingsley chose to let NBT's bond portfolio mature naturally and reinvest the cash flows. Average taxable securities reached $2.67 billion this quarter, and the average yield on those bonds rose 0.06 percentage points from last quarter to 2.76%, up 0.30 points from a year ago.
Tax-exempt securities added another $230.4 million at a 3.57% yield. That steady reinvestment lifted interest income on available-for-sale bonds by 29.6% from a year ago to $15.6 million, helping offset a 0.11 percentage point drop in loan yields over the same twelve months without taking a capital hit.
What to watch: the average yield on taxable securities in the fourth quarter. Continued increases above 2.76% would confirm that maturing bonds are still rolling into higher rates.
🐻 Bear Case
Past-Due Loans Cured, Yet Troubled Loans Still Rose
Three months ago, NBT said the majority of its overdue commercial loans would return to current status in the third quarter. Total overdue loans still accruing interest did fall by 0.28 percentage points to 0.35% of the loan book, "driven primarily by a decrease in past due commercial loans". Yet total nonperforming loans — loans no longer paying interest or 90 days overdue — still climbed.
- Nonperforming loans: $70.0 million (0.59% of loans), up 7.2% from last quarter and 35.3% since December
- Allowance for loan losses: $140.0 million (1.17% of loans), down $0.5 million from last quarter
- Reserve coverage of nonperforming loans: 200.1%, down from 266.8% at year-end
The bank cited "additional commercial lending relationships placed in nonaccrual status during the quarter" and higher overdue residential mortgages. Even as problem loans grew, NBT cut its quarterly loan-loss provision to $3.8 million and trimmed total reserves, citing "improvement in economic forecasts and portfolio mix changes".
What to watch: nonperforming loans in the quarterly filing's credit footnote. A fourth straight quarterly rise would show that commercial borrowers are still slipping into default.
Loan Growth Cooled After the Second-Quarter Catch-Up
NBT's loan book grew by $326.8 million in the second quarter, when delayed winter closings and auto lending came through at once. In the third quarter, net loan additions slowed to $74.4 million, or 0.6% from last quarter, leaving total loans at $11.95 billion (up 3.0% from a year ago, or 4.2% by our math excluding the shrinking solar and consumer books).
Commercial real estate added $62.4 million during the quarter, residential mortgages added $25.8 million, and home equity added $15.8 million. However, commercial and industrial loans shrank by $6.1 million and indirect auto loans edged down $0.8 million, while the residential solar and other consumer books in planned run-off shrank by another $22.7 million to $728.6 million.
What to watch: fourth-quarter net loan additions outside the solar run-off book. Another quarter below $100 million would show that pricing competition is capping commercial and auto lending.
Short-Term Borrowings Funded the Balance Sheet Growth
NBT is leaning more on wholesale debt to fund its loan and bond purchases because total deposits have barely moved over the past year. Period-end deposits stood at $13.59 billion, up 0.4% from last quarter and down 0.5% from a year ago as customers let $325.6 million of higher-rate time deposits run off over the past twelve months.
With loans growing faster than deposits, the loan-to-deposit ratio rose to 87.9% from 85.9% at year-end. To bridge the gap, short-term borrowings nearly tripled from $148.1 million at December 31 to $414.4 million at September 30. Average short-term debt and federal funds purchased cost roughly 3.8% to 4.0% this quarter, compared with 1.32% for deposits.
What to watch: short-term borrowings and the loan-to-deposit ratio at year-end. Further borrowing growth would push funding costs up and squeeze the lending margin.
👓 Other Themes
One Net New Branch Opened Across the Northeast
NBT has been hiring bankers and opening branches in markets such as Rochester and southern Maine while studying fill-in acquisitions. The bank operated 174 locations at quarter-end, up by one from June and down one from a year ago, and occupancy expenses rose $0.5 million from a year ago to $9.6 million on new branch facilities. The release gave no update on potential bank acquisitions.
💲 Other KPIs
Tangible book value per share — net worth per share excluding goodwill and other merger intangibles — rose 8.8% from a year ago and 4.6% since December. Retained profit built common equity tier 1 capital (a core bank safety buffer) to 12.43%, up 0.19 percentage points from last quarter, though bond value swings trimmed $0.04 from sequential book value growth.
Diluted share count fell 0.8% from a year ago and was unchanged from the second quarter. The bank bought back 20,118 shares for $1.0 million (an average of $50.02 each) during the third quarter, down from $3.0 million in the second quarter, before repurchasing another 113,364 shares in October.
🔮 Guidance
Unchanged from the third quarter and up 8.1% ($0.03 per share) from a year ago. NBT raises its dividend once a year in the third quarter, and this payout continues its 14-year streak of annual increases. The bank does not issue quarterly revenue or earnings ranges in its press release.
❓ Key Questions
Will purchase accounting accretion drop back in the fourth quarter?
Merger accounting income jumped by $1.5 million in the third quarter, adding about 0.04 percentage points to the 3.78% lending margin. Knowing the fourth-quarter run rate tells investors how much of the margin gain is permanent.
Why did nonaccrual loans rise while overdue loans cured?
Overdue accruing loans dropped 0.28 percentage points to 0.35% of loans, yet nonaccrual loans still rose by $2.6 million to $65.5 million. Management has not said whether the new defaults came from the second-quarter overdue list or separate borrowers.
Does the 2.5%–3% full-year expense growth target still hold?
Operating expenses excluding merger costs rose 4.7% from a year ago in the third quarter to $115.2 million. Management did not update its full-year expense outlook in the release or clarify the comparison base.
Why did share buybacks jump in October after slowing?
NBT bought only 20,118 shares in the third quarter at $50.02, then bought 113,364 shares between October 1 and October 24. Clarifying the price paid in October will show whether management changed its buyback rules.
