BankUnited (BKU) Q3 2026 earnings review
BankUnited's margin widens, but its deposits and loans both shrink
BankUnited earned more on each dollar it lends, but its deposits and its loans both shrank in the quarter. Chief executive Rajinder Singh said the margin reached 3.16%, ahead of the bank's own target. Profit per share rose 6%, mostly from buybacks; net income hardly moved. By our math, the fourth-quarter outlook has full-year interest income growing about 4%, below the July plan.
| Net interest margin | 3.16% 3.06% last quarter; 3.00% a year ago |
|---|---|
| Profit per share | $1.01 +6% from a year ago |
| Core loans at quarter end | $17.2 billion down $32 million from June |
| Fourth-quarter outlook | Margin raised to 3.20% but implies about 4% full-year interest income growth, below the 5–6% July plan |
⚖️ Verdict: 🔴 Bearish
The story got worse because the two balance-sheet lines the case rests on both went backwards. Free deposits stopped growing and core loans slipped for a third quarter, so the fourth-quarter outlook sits below every July target except the margin. The good news: the margin reached its year-end level early and credit losses stayed low.
The question now is whether the fourth quarter brings the loan and deposit growth the outlook needs. One answer is that the deposit drop was seasonal and loans close in December as they did last year; the other is that competition has set a ceiling, so interest income grows only as fast as the margin. Year-end core loans against the $17.6–17.7 billion outlook will tell.
🐂 Bull Case
Margin Reaches 3.16%, Above the Bank's Own Plan
Net interest margin is the gap between what a bank earns on loans and bonds and what it pays for deposits and borrowings. BankUnited set a year-end target of 3.15% in July, after lowering it from 3.20%. Chief executive Rajinder Singh pointed to "net interest margin expanding to 3.16%" this quarter, so the target fell a quarter early.
Three things widened it. The bank paid 1.99% on average for deposits, down from 2.05% in June, because it kept trimming rates on interest-bearing accounts. It also made a "strategic sale of lower-yielding securities of approximately $1.0 billion" at a $2.3 million loss and bought higher-yielding bonds. The yield on the bond book rose 0.12 percentage points as a result, and business loan yields added 0.05 points.
- Margin: 3.16%, up 0.10 points from June and 0.16 points from a year ago
- Average cost of deposits: 1.99%, down 0.39 points from a year ago
- Interest-bearing borrowings and deposits: down $1.0 billion from a year ago on average
- Fourth-quarter outlook: about 3.20%, the level first set in January
This matters because the margin is now the only line running ahead of the plan. Interest income rose 4% from a year ago on a loan book that did not grow, so the whole gain came from cheaper funding and a better bond mix. The bank now expects about 3.20% in the fourth quarter and assumes a 0.25-point rate rise in December.
What to watch: the fourth-quarter margin against the 3.20% outlook, reported in January. A reading at or above it would show the bank can keep widening its margin even while its cheapest deposits fall.
Loan Losses Fall to a Six-Quarter Low
Banks set aside a provision each quarter for loans that may not be repaid, and it is the largest swing in BankUnited's profit. The bank set aside $9.0 million this quarter, down from $15.6 million in June. The company put the drop at 23% from a year ago.
- Loans written off: $6.3 million, or 0.11% of loans annualised, against 0.25% a year ago
- Loans flagged as weak (criticized and classified): $1.05 billion, down 14% from a year ago
- Fourth-quarter provision outlook: about $15 million, which puts the full year near $64 million by our math, under the $68–72 million range set in July
The low charge is what kept net income level, because profit before credit costs fell 3% from a year ago. The reserve still grew, since the bank added $9.2 million for "Economic uncertainty and model imprecision" rather than for any named loan.
What to watch: fourth-quarter write-offs against the $15 million provision outlook. Write-offs near this quarter's level would mean the higher provision builds reserves rather than covers new losses.
Buybacks Lift Profit Per Share While Net Income Stands Still
BankUnited bought back about 2.1 million shares for $97.0 million in the quarter, its largest purchase of the year. The diluted share count is 5.7% lower than a year ago. That is why profit per share rose 6% on net income that hardly moved.
- Net income: $72.2 million, up $0.3 million from a year ago
- Repurchases year to date: $206.7 million; about $49 million of authorisation left by our math
- Common equity tier 1 ratio, the main regulatory capital measure: 12.1%, down from 12.3% in June
The cost is a thinner capital base. Tangible book value per share fell 3% from June because higher rates cut the market value of the bank's bonds, and the outlook says it will "Utilize remaining stock buyback capacity by year end". Per-share growth therefore depends on the board approving a new block.
What to watch: the size of the next repurchase authorisation once the current one runs out. A block near this year's would keep per-share profit rising even if net income does not.
Positives this quarter didn't test
Two standing drivers got no full reading, because the materials came without a transcript or a quarterly filing and the release does not break out results by market or by fee line in detail.
- Fee income from deposit accounts: service charges rose 19% from a year ago to $6.4 million, but a securities loss, an equipment write-down and weaker capital markets fees took total fee income down 23%; new fee lines by product would show whether the core is still compounding.
- Expansion in Dallas, Charlotte, Atlanta and Tampa: no hiring or loan production figures by market; a production split by region would show whether the new offices are producing loans.
🐻 Bear Case
Non-Interest Deposits Fall, Outlook Has Them Lower
Non-interest-bearing deposits are money customers leave with the bank for free, and they are the reason BankUnited's margin has widened for three years. Its two largest sources are title companies, with $4.7 billion, and homeowner associations, with $2.4 billion. Chairman and chief executive Rajinder Singh opened the release with "continued deposit momentum". The quarter's numbers say otherwise.
- Average non-interest deposits: $9.03 billion, flat from June and up 10% from a year ago
- Quarter-end balance: $9.11 billion, down $821 million, or 8%, from June
- Brokered deposits, bought through third parties: 14.6% of deposits, up from 10.5% in June
- Fourth-quarter outlook for average non-interest deposits: about $8.65 billion, below the same quarter last year by our math
The company said the drop was "seasonal normalization following elevated inflows in Q2". That is plausible, because the title business swings with home sales and the same thing happened a year ago. But the outlook is the harder evidence: a fourth-quarter average of $8.65 billion would sit below last year's $8.71 billion, the first decline from a year earlier the bank has pointed to. By our math that leaves full-year average growth near 9%, against the 13% set in July. The replacement funding costs money: brokered balances rose about $1.1 billion in the quarter and Federal Home Loan Bank borrowings rose $295 million. A December rate rise, which the outlook assumes, raises what rivals can pay for the same deposits.
What to watch: fourth-quarter average non-interest deposits against the $8.65 billion outlook, in January. A figure above last year's $8.71 billion would show the third-quarter drop was seasonal rather than a loss of customers.
Loans Fall Again and the Year's Target Drops
BankUnited's plan for this year rested on core loans growing 6%, a figure it cut to 4–5% in July. Core loans are commercial real estate, business loans, mortgage warehouse lines and municipal finance. They fell $32 million in the quarter to $17.17 billion and sit $18 million below where they started the year.
The business loan book is the problem. Customers repaid $594 million of commercial and industrial loans while the bank produced $508 million of new ones, so that book shrank. Loans to non-bank lenders, a $1.3 billion slice of it, are down $200 million this year.
- Commercial and industrial loans: down $109 million from June
- Commercial real estate: up $66 million; mortgage warehouse: up $56 million
- Residential mortgages, which the bank runs off on purpose: down $70 million
- Fourth-quarter outlook for core loans: $17.6–17.7 billion, which needs $430–530 million of growth in one quarter
The new outlook is a cut in all but name. By our math, $17.6–17.7 billion at year end is 2.4–3.0% growth for the year, under the 4–5% range set in July. The bank has added that much in a single quarter once in the past six, in late 2025. Business loan yields rose 0.05 points, so the bank is holding its pricing; the cost is that borrowers refinance elsewhere.
What to watch: year-end core loans against the $17.6–17.7 billion outlook. Falling short again would mean the bank cannot grow its loan book at the prices it insists on, and interest income would then depend on the margin alone.
Problem Loans Rise Even as Loss Charges Fall
The headline credit numbers improved, but the loans one step from a loss did not. Non-performing loans, which no longer pay interest, rose $40 million from June to $264 million. Business loans drove it: their non-performing balance rose $43 million to $178 million.
- Non-performing loans: $264 million, up 18% from June and down 30% from a year ago
- Substandard accruing loans, still paying but flagged: $731 million, up $45 million from June
- Reserve as a share of non-performing loans: 84%, down from 97% in June
The release headline promises "Improved Credit Trends", and the comparison with a year ago supports that. But the move from June runs the other way for a second quarter: weak-but-paying business loans grew again, while the fall in the total came from commercial real estate, where the flagged balance dropped $54 million. Office remains the standing exposure; its non-performing loans stayed at $29 million and the reserve on it rose to 2.04%.
What to watch: non-performing business loans and substandard accruing balances in the fourth-quarter release. Another rise would mean the $15 million provision the bank now plans is the start of higher credit costs, not a one-off.
Costs Rise 5% While Revenue Grows 2%
Revenue before credit costs, meaning interest income plus fees, grew 1.7% from a year ago to $280 million. Operating costs grew 5.0% to $175 million. Profit before credit costs therefore fell 3.3% to $106 million, the lowest of the past five quarters.
- Deposit-related costs, what the bank pays to win and service deposits outside interest: $23.6 million, up 23% from a year ago, or 8.4% of revenue against 7.0%
- Employee pay: $89.6 million, up 5.2%
- Fee income: $19.8 million, down 23%, including a $2.3 million securities loss and a $1.1 million equipment loss
- Fourth-quarter outlook: costs about $178 million, fees about $28 million
The company said costs rose "as a result of increases in employee compensation and deposit-related costs due to competition". That is the trade the bank makes: it wins deposits that pay no interest by spending on them another way, and this quarter it spent more while the balances fell.
What to watch: deposit-related costs in the fourth quarter against the $8.65 billion deposit outlook. A cost line that keeps rising while balances fall would mean the bank is paying up to keep the deposits it has.
👓 Other Themes
Outlook Assumes a December Rate Rise
The fourth-quarter outlook rests on two listed assumptions: "Continued economic strength" and a "25 bps rate increase in December 2026". A December move arrives too late to change fourth-quarter interest income much, so the 3.20% margin outlook mostly reflects the funding mix already in place. The tax rate assumption fell to about 25.5% from the 26% set for the year in January.
💲 Other KPIs
Growing faster each quarter: up 18% from June and 35% from a year ago. Mortgage warehouse lending is short-term credit to mortgage companies while they sell loans on, so it swings with home sales. It is the one core segment adding balances at pace, but it is small and the company says it earns less than business loans.
Larger again: the paper loss on the bank's bond portfolio rose $171 million from June, after $282 million in June and $267 million at year end. Higher market rates cut bond prices, and the loss flows through equity rather than profit, which is why tangible book value per share fell while net income held. The bank says it expects no credit losses on these bonds.
Up from 82.9% in June and 82.8% a year ago. Loans fell in the quarter, so the rise came entirely from deposits falling faster. A higher ratio means less cheap funding behind each dollar lent, which is consistent with the bank adding brokered deposits and Federal Home Loan Bank borrowings during the quarter.
🔮 Guidance
Cut. The new range means core loans end the year 2.4–3.0% above where they started, below the 4–5% set in July. By our math the bank must add $430–530 million in the fourth quarter after losing $32 million in the third. December is its seasonal peak. It has managed a quarter that large once in the past six, in late 2025, when core loans grew $751 million.
Cut in effect. The outlook has free deposits averaging about $8.65 billion, down from $9.03 billion this quarter. That is below the same quarter last year by our math, the first such decline the bank has pointed to. It leaves full-year average growth near 9%, against the 13% set in July, even after a first half that ran ahead of plan.
Cut by implication. About $265 million in the fourth quarter is 2% above this quarter and 3% above a year ago. Added to the nine months booked, by our math the year lands near 4.3% growth, under the 5–6% set in July and well under the 9% in the January plan. The margin carries it, because both the loan book and the deposit book are smaller than in June.
Raised. The year-end margin outlook returns to the 3.20% set in January, after July's cut to 3.15%; this quarter's 3.16% already passed the lower figure. The outlook assumes a December rate rise, which adds little inside the quarter, so most of the gap must come from the bond sale and lower deposit rates. By our math the full-year margin would be about 3.11%, above the 3.08% set in July.
Cut by implication. About $28 million in the fourth quarter is a rebound from this quarter's $19.8 million, which carried a $2.3 million securities loss. By our math the year ends near $102 million, about 4% below 2025, against the 7% growth set in July. Deposit service charges keep rising; the shortfall sits in lease income, life-insurance returns and capital markets fees.
Unchanged in effect. About $178 million in the fourth quarter is 2% above this quarter and 3% above a year ago. By our math that puts the full year up 4.7%, inside the 5% set in July. Costs tied to deposits are the line to follow: they rose 23% from a year ago this quarter while deposit balances fell.
New. Pre-provision net revenue, meaning revenue minus operating costs before credit charges, of about $115 million would be 9% above this quarter and level with a year ago. The full year would then rise under 2% by our math, after nine months in which costs grew faster than revenue. The gain over this quarter comes from fees recovering and interest income rising, not from lower costs.
Cut in effect. About $15 million in the fourth quarter is above this quarter's $9.0 million but below the $25.6 million of a year ago. By our math the full year ends near $64 million, under the $68–72 million range set in July, so credit costs come in lighter than the bank planned. The step up from this quarter matches the rise in non-performing business loans.
Lowered. About 25.5% matches this quarter's effective rate and sits under the 26% assumed for the year since January. On the outlook's pre-provision profit and provision, by our math that implies fourth-quarter net income near $75 million, about 8% above a year ago, before any further buyback effect on the per-share figure.
❓ Key Questions
What yields and spreads did new loans carry this quarter?
The bank blames pricing competition for weak loan growth, yet it stopped disclosing new-production yields in July. Business loan yields rose 0.05 points on average, but that says nothing about what new deals pay.
How much fourth-quarter loan growth is already committed?
The outlook needs $430–530 million of core loans in one quarter after three quarters of nothing. A closed-and-committed figure would show whether that is a pipeline or a hope.
Did deposit customers leave, or was the drop seasonal?
Quarter-end free deposits fell $821 million and the fourth-quarter outlook sits below last year. A split between title, homeowner-association and other balances would show whether a relationship was lost.
Which business loans became non-performing this quarter?
Non-performing business loans rose $43 million and substandard accruing loans rose $45 million while the release reports improved credit. The industries and sizes involved would show whether this is one borrower or a pattern.
What do the free deposits cost once rebates are counted?
Deposit-related costs rose 23% from a year ago to $23.6 million. An all-in cost of the non-interest deposit book, by vertical, would show how free those deposits really are.
