Is BKU a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The bull case for BankUnited (BKU) rests on Deposit mix shift toward lower-cost funding: A central part of BankUnited's strategy is growing non-interest-bearing demand deposits and reducing reliance on higher-cost wholesale and time deposits. Full-Year 2025 Diluted EPS is ~$3.53. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: As a mid-cap regional bank, BankUnited is highly sensitive to interest rates, because net interest income is its largest revenue line and falling rates or renewed deposit-cost pressure can compress margin. Whether BKU is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
BankUnited, Inc. (NYSE: BKU) is the bank holding company for BankUnited, N.A., a national bank headquartered in Miami Lakes, Florida, with roughly $35 billion in total assets at December 31, 2025. It provides a full range of consumer and commercial banking products to individuals, small businesses, middle-market companies, and larger corporations, with banking centers concentrated in Florida and the New York tri-state area plus a commercial presence in Dallas, Atlanta, Charlotte, and Morristown, New Jersey. Like most banks, BankUnited earns money primarily from net interest income (the spread between what it earns on loans and securities and what it pays for deposits and funding), supplemented by fee income from deposit services, lending, and treasury products. The investment picture centers on BankUnited's multi-year effort to reshape its balance sheet toward a lower-cost, more relationship-driven deposit base. Management has emphasized growing non-interest-bearing demand deposits (which reached roughly 30 percent of total deposits during 2025), running off higher-cost wholesale and time deposits, and expanding core commercial loans, all of which support net interest margin. In full-year 2025 the company reported net income of about $268 million and diluted EPS of about $3.53, up roughly 15 percent year over year, with net interest margin expanding toward about 3 percent. As a mid-cap regional bank (market capitalization around $3.5 billion in mid-2026), BKU is economically cyclical and sensitive to interest rates, the health of Florida and New York commercial real estate, and broader credit conditions.
What's the case for buying BKU?
1. Deposit mix shift toward lower-cost funding
A central part of BankUnited's strategy is growing non-interest-bearing demand deposits and reducing reliance on higher-cost wholesale and time deposits. Non-interest-bearing deposits grew during 2025 and reached roughly 30 percent of total deposits, and the fourth quarter added about $485 million of non-interest-bearing deposit growth. A cheaper, stickier deposit base directly supports net interest margin and is the lever management points to most often.
2. Net interest margin expansion
BankUnited's net interest margin improved through 2025, moving from the low-2.8 percent range earlier in the year toward roughly 3 percent, with the fourth quarter reflecting about 6 basis points of further expansion. Margin is the single biggest driver of a bank's earnings, and continued repricing of assets, lower deposit costs, and the runoff of expensive funding are what management is counting on to keep it rising.
3. Core commercial loan growth
The company is targeting organic growth in core commercial and small-business lending in its Florida and New York markets, adding roughly $769 million of core loan growth in the fourth quarter of 2025. As a relationship-focused regional bank, BankUnited leans on localized commercial deal flow rather than national-scale consumer lending, so steady core loan growth without loosening credit standards is important to the earnings story.
4. Capital return through dividends and buybacks
BankUnited pays a quarterly dividend (raised by $0.02 to about $0.33 per share alongside its fourth-quarter 2025 results) and repurchases stock, having expanded its buyback authorization by an additional $200 million. Returning capital while growing modestly is characteristic of a mature regional bank, and it gives shareholders a yield component on top of any change in the share price.
What are the risks to BKU?
As a mid-cap regional bank, BankUnited is highly sensitive to interest rates, because net interest income is its largest revenue line and falling rates or renewed deposit-cost pressure can compress margin. It is economically cyclical and exposed to the credit cycle, particularly commercial real estate and commercial lending in Florida and the New York tri-state area, where a downturn, rising vacancies, or higher unemployment would increase loan losses. Regional banks also carry funding and liquidity risk, a concern underscored by the 2023 regional-banking stress, so deposit stability and the mix of insured versus uninsured deposits matter. Its geographic concentration in Florida adds exposure to hurricane, insurance-market, and regional-economic shocks. Finally, competition from national banks (such as JPMorgan Chase and Bank of America) and aggressive regionals can pressure both loan pricing and deposit costs.

BankUnited trades as a mid-cap regional bank, and bank valuation is usually framed on price-to-earnings and price-to-tangible-book-value rather than revenue multiples. On roughly $3.53 of 2025 diluted EPS and a share price in the high-$40s during mid-2026, the stock has carried a price-to-earnings ratio in the mid-teens. As with any bank, reported earnings can swing with provisions for loan losses, so tangible book value and credit trends are watched alongside EPS.
How do you decide if BKU is a buy?
Rather than asking whether BKU is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold BKU indirectly through an index or sector ETF before adding more.
