FirstSun Capital Bancorp (FSUN) Q3 2026 earnings review
FirstSun's lending margin rebounds, but its overdue loans still climb
FirstSun Capital Bancorp, the parent of Sunflower Bank, rebounded from last quarter's merger loss as cheaper funding lifted its lending spread. Profit per share excluding merger charges more than doubled from the second quarter to $1.03, and chief executive Neal Arnold completed the First Foundation computer system conversion on schedule in late September. However, loan and deposit balances shrank again, while overdue loans climbed to nearly 2% of the portfolio.
| Net interest margin | 3.82% up 0.24 percentage points from last quarter |
|---|---|
| Profit per share, excluding one-offs | $1.03 $0.45 last quarter and $0.83 a year ago |
| Nonperforming loans to total loans | 1.77% up from 1.64% last quarter |
| Q4 loan and core deposit outlook | Raised to mid-single-digit growth from low-single-digit |
⚖️ Verdict: 🟢 Bullish
The story got better because the post-merger balance sheet cleanup delivered real margin relief and loan write-offs dropped to $3 million from $42 million last quarter. Even stripping out merger accounting gains, the core lending margin widened by 0.22 percentage points by our math, and management raised its fourth-quarter loan and deposit growth targets. One caution: credit stress has not cleared, as loans in the worst risk grade before write-off jumped 71% to $42 million and legal collection bills rose.
The question now is whether the growing pile of overdue commercial real estate loans will turn into actual losses or resolve without breaking the bank's cost and profit plans. If the bank's collateral holds up, remaining merger cost cuts and share buybacks will drive earnings higher; if defaults spread, credit provisions and collection costs will eat up those gains. Fourth-quarter loan write-offs and nonperforming loan balances will tell.
🐂 Bull Case
Lower Funding Costs Lifted the Lending Margin
FirstSun's net interest margin (NIM), the profit spread between what the bank earns on loans and pays on deposits, rebounded after last quarter's merger dilution. Chief executive Neal Arnold pointed to an "improved net interest margin as a result of continued balance sheet improvements" following the April acquisition of First Foundation.
The bank sold off $1.3 billion of lower-yielding loans and shed $2.5 billion of expensive deposits late in the second quarter. That cleanup paid off across the third quarter. Even excluding the $25.6 million accounting boost from marking acquired loans to market, the underlying lending margin widened by 0.22 percentage points to 3.12% by our math.
- Reported net interest margin: 3.82%, up 0.24 percentage points from last quarter
- Average loan yield: 6.33%, up 0.17 percentage points
- Total cost of funds: 2.26%, down 0.08 percentage points
- Noninterest-bearing share of average deposits: 20.3%, up from 18.1% in Q2
This matters because the margin gain came from real funding relief rather than accounting adjustments. Management expects the lending margin to reach the mid-3.80% range in the fourth quarter and the high-3.80% range in early 2027, even as the merger accounting boost drops to $20–25 million next quarter.
What to watch: underlying net interest income excluding merger accounting adjustments in the fourth quarter. A higher figure would prove that core deposit repricing is outrunning the natural fade of acquisition accounting income.
System Conversion Completed Ahead of Cost Targets
Combining two banks onto one technology platform is a major operational hurdle in any bank merger. Arnold said that "in late September, we successfully completed the core system conversion of First Foundation, representing another important milestone in our overall integration plan".
Moving onto one system allowed the bank to cut duplicate staff and vendor contracts ahead of schedule. FirstSun noted in its presentation: "Merger-related cost saves trending above expectations with approximately 70% of the total announced savings achieved through 3Q", up from 65% last quarter. Salary and employee benefits fell $5.4 million from the second quarter to $63.3 million, or 35.3% of total revenue (down 2.1 percentage points).
However, total operating expenses excluding merger charges dipped only $0.8 million to $113.3 million, and the adjusted efficiency ratio (operating expenses as a share of revenue, where lower is better) worsened by 1.1 percentage points to 63.1%. That happened because revenue dipped 2.4% on a smaller balance sheet and other expenses rose $4.5 million to 15.3% of revenue (up 2.8 percentage points) "primarily driven by higher loan collection expenses".
What to watch: fourth-quarter operating expenses excluding merger charges and loan collection costs. A drop toward the low-60% efficiency target in the first quarter of 2027 will show the remaining 30% of cost cuts have landed.
Wealth Fees and Swaps Cushion Mortgage Drop
FirstSun aims to generate over 20% of its revenue from service fees so it relies less on interest rates. In the third quarter, noninterest income made up 21.9% of total revenue, or $39.4 million. While mortgage banking revenue dropped $3.2 million from the second quarter to $12.7 million on lower loan sales and servicing valuation changes, other fee lines filled the gap.
Trust and investment advisory fees — expanded by First Foundation's wealth management business — rose 5.0% from last quarter to $9.9 million, making up a quarter of all fee income. In addition, fees from interest-rate swaps and loan syndications more than tripled from the second quarter to $2.8 million. That mix kept total fee revenue near $40 million despite slower home-loan sales.
What to watch: wealth management assets under management and advisement, which dipped 1.3% this quarter to $7.33 billion. Growing those client balances is necessary to keep advisory fees rising now that the initial merger step-up is complete.
🐻 Bear Case
Overdue Loans Still Climb Despite Lower Write-Offs
FirstSun's loan write-offs dropped after a rough second quarter, and Arnold highlighted "a balanced risk profile" and "improved earnings performance". Net charge-offs (loans written off as uncollectible) fell to $3.3 million, or 0.11% of average loans on an annualized basis, down from $42.4 million (1.45%) last quarter. Total criticized loans — the bank's watch list of troubled borrowers — also declined by $63.8 million to $831.4 million.
Yet severe credit stress beneath the headline write-off number continued to build. Nonperforming loans (loans past due 90 days or no longer accruing interest) rose another $12.7 million to $202.9 million, or 1.77% of all loans. The bank set aside a $4.4 million credit provision "primarily reflecting specific reserves established for two CRE loans", and loans graded doubtful (the worst category before a write-off) jumped 71% to $41.8 million.
- Nonperforming loans: 1.77% of total loans, up from 1.64% in Q2 and 0.86% in Q1
- Doubtful loans: $41.8 million, up $17.4 million from Q2 on two commercial real estate loans
- Criticized multifamily real estate loans: $350.9 million, or 42% of all criticized loans
- Loan collection expenses: drove a $4.5 million jump in other noninterest expense
Because one print fades a concern only while the underlying pipeline improves, the rise in nonperforming and doubtful loans keeps credit risk front and center. Furthermore, FirstSun expects annualized net charge-offs to rise to the low-20s basis points in the fourth quarter.
What to watch: how the $41.8 million of doubtful loans and $202.9 million of nonperforming loans resolve in the fourth quarter. If write-offs breach the low-20s basis points plan, credit costs will eat into 2027 profit.
Loans and Deposits Shrank After the Cleanup
FirstSun completed its planned post-merger balance sheet downsizing in the second quarter, so the third quarter was the first test of organic stability. Instead of growing, both total loans and deposits contracted. Period-end loans fell by $110.6 million (3.8% annualized) to $11.46 billion, and deposits dropped by $447.0 million (13.2% annualized) to $12.97 billion.
Commercial and industrial loans grew 2.3% from last quarter (+$83.9 million), but commercial real estate paydowns (-$122.2 million, including an 11% annualized drop in multifamily loans) outweighed new lending. On the funding side, FirstSun shed $42 million of brokered deposits and $255 million of higher-rate non-relationship accounts, alongside $65 million of seasonal outflows and $85 million of other declines.
Despite the third-quarter shrinkage, the company raised its fourth-quarter outlook for both loans and core deposits from low-single-digit to mid-single-digit growth. Because third-quarter balances shrank while the fourth-quarter forecast stepped up, the bank must reverse customer outflows immediately.
What to watch: fourth-quarter net new loans and deposits excluding brokered accounts, which must grow by roughly $143 million and $151 million by our math to hit the mid-single-digit plan. Missing that target would show that multifamily runoff and deposit attrition are overriding core commercial growth.
Aggressive Buybacks Keep Capital Near Floor
After the First Foundation acquisition dropped FirstSun's Common Equity Tier 1 (CET1) capital ratio — a core measure of a bank's cushion against loan losses — from 13.77% to 11.95% in the second quarter, the board authorized a $150 million share repurchase plan. In the third quarter, the bank spent $49.7 million to buy back 1.25 million shares, using up a third of the four-quarter authorization in a single quarter.
That pace reduced period-end shares by 2.6% to 45.55 million, which will boost future earnings per share. However, it consumed nearly all of the $38.4 million in quarterly net income and the capital freed up by a shrinking balance sheet. As a result, the CET1 ratio edged up just 0.04 percentage points to 11.99%, sitting right at the top of management's 11.75%–12.00% expected range.
What to watch: the quarterly buyback pace across the remaining $100 million authorization over the next three quarters. If overdue commercial real estate loans require larger loss provisions, the bank will have little excess capital above its target band to absorb them while continuing repurchases.

Rate Sensitivity Sits on a Floating Loan Book
FirstSun keeps a slightly asset-sensitive balance sheet, meaning its loan yields react slightly faster to interest rate moves than its deposit costs. About 70% of its loans carry variable interest rates, and 37% reprice every month. Management's fourth-quarter outlook assumes the Federal Reserve raises interest rates by 0.25 percentage points before year-end, which would lift floating loan yields.
💲 Other KPIs
Rose $0.44, or 1.3%, from last quarter after falling 8.8% in the second quarter when the First Foundation merger closed. Tangible book value per share measures the bank's net worth per share excluding goodwill and intangible assets. Quarterly earnings and lower intangible balances outweighed the $49.7 million spent on share buybacks and higher unrealized bond losses.
Moved up 2.1 percentage points from 86.2% in the second quarter as deposits shrank faster than loans, staying inside the bank's mid-to-high 80% target range. Before the acquisition and balance sheet cleanup, the ratio ran between 93.9% and 97.9%. Wholesale funding (brokered deposits and short-term borrowings) edged down to 6.7% of total liabilities from 6.8%.
Increased by 0.02 percentage points from 1.50% last quarter (and up from 1.20% before the merger) to $174.6 million. The allowance is the reserve set aside for future loan defaults. Because nonperforming loans grew faster than the reserve, allowance coverage of nonperforming loans fell for a third straight quarter to 86.1%, down from 91.3% in Q2 and 139.1% in Q1.
🔮 Guidance
Raised. The bank now plans for mid-single-digit annualized loan growth in the fourth quarter, up from its prior low-single-digit outlook, and maintained its mid-single-digit target for 2027. By our math, a 5% annualized pace implies adding about $143 million in net new loans next quarter, reversing this quarter's $111 million contraction.
Raised. FirstSun lifted its fourth-quarter deposit growth outlook to mid-single digits (now specified as excluding brokered deposits) from low-single digits previously, while keeping its 2027 deposit growth plan at mid-single digits. By our math, that implies adding roughly $151 million of customer deposits in the fourth quarter after shedding $405 million of non-wholesale deposits in the third quarter.
Raised. The outlook for investment securities moved up to high-single-digit growth for the fourth quarter, compared to a flat forecast three months ago. Securities fell by $81.1 million (or 4.2%) in the third quarter to $1.86 billion.
Unchanged. The forecast keeps the lending margin rising to roughly 3.85% in the fourth quarter (up 0.03 percentage points from Q3's 3.82%) and around 3.88% in the first quarter of 2027. That expansion comes even as contractual pre-tax merger accounting income steps down from $25.6 million in Q3 to an expected $20–25 million in Q4 (and $85–90 million for full-year 2027).
Unchanged for Q4, narrowed for Q1 2027. The bank still expects operating costs as a share of revenue to improve to the low-60% range in the fourth quarter from 63.1% (excluding merger charges) in Q3. However, for the first quarter of 2027, it now points to the low-60s% rather than its earlier high-50s% to low-60s% range (a softer cost-to-revenue target).
Unchanged. Service fees are still planned to make up a low-20% share of total revenue in the fourth quarter, matching the 21.9% delivered in the third quarter and 22.2% in the second quarter.
Unchanged. Annualized loan write-offs are projected in the low-20s basis points (around 0.21%–0.23% of average loans) in the fourth quarter, up from 0.11% in the third quarter as problem loans resolve.
Raised. The loan loss reserve ratio is now expected to stay in the low-1.50% range in the fourth quarter (matching Q3's 1.52%), up from the prior mid-1.40% outlook, reflecting higher specific reserves on commercial real estate loans.
❓ Key Questions
What drove the $17 million jump in doubtful loans?
Doubtful loans rose 71% to $41.8 million on two commercial real estate relationships, carrying a 56% loss reserve. Investors need to know whether these properties came from First Foundation or the legacy bank, and when their workouts will conclude.
Why trim the early 2027 efficiency target to low-60s?
Management achieved 70% of merger cost savings ahead of schedule and completed the system conversion, yet narrowed its Q1 2027 efficiency outlook from high-50s/low-60s% to low-60s%. Is higher loan collection expense or new branch hiring eating into the savings?
Why assume a Fed rate hike in the fourth quarter?
The fourth-quarter outlook table lists a 0.25 percentage point Federal Reserve rate increase by year-end as a key assumption. Since 70% of the loan book floats, how much would a rate cut or flat rates reduce the mid-3.80% margin forecast?
What will reverse the $447 million deposit outflow in Q4?
Even after completing its planned balance sheet cleanup in Q2, FirstSun lost $255 million of higher-rate non-relationship deposits and $150 million of seasonal and other balances in Q3. Which deposit channels will drive the raised mid-single-digit growth plan in Q4?
