Bankwell: Margin Expansion and a Raised Bar — Scale Is Working

Q2 2026 net interest margin jumps 30bps, core deposits surge, and guidance moves higher as the bank's disciplined operating leverage pays off.

BWFG · Earnings Call · 2026-07-23

What changed this quarter?

Bankwell Financial Group turned in a second quarter that was hard to ignore: net interest margin expanded 30 basis points to 3.58%, loans grew 3.2% sequentially, and core deposits rose $128 million — including $72 million of growth in noninterest-bearing and NOW accounts. As CEO Chris Gruseke put it, “Second quarter marked another period of strong execution with meaningful margin expansion, robust core deposit and loan growth and continued progress on our strategic priorities, including the continued success of our SBA division.” — Christopher Gruseke, President and Chief Banking Officer · 2026-07-23 The momentum is not just in the headline numbers; the bank raised its full-year guidance for loan growth, net interest income, and even expenses — a deliberate move that signals confidence in the franchise's ability to scale profitably.

CFO Courtney Sacchetti explained the drivers: “Net interest margin expanded 30 basis points to 3.58%, driven by favorable repricing. Deposit costs improved 16 basis points to 2.94%, while our earning asset yields rose 11 basis points to 6.26% as new loan production at an average rate of 7.16% continued to outpace runoff.” — Courtney Sacchetti, Executive Vice President and Chief Financial Officer · 2026-07-23 This is textbook balance-sheet optimization: the deposit side repriced faster than the asset side, thanks to a deliberate strategy of paying down higher-cost wholesale funding and growing lower-cost core deposits.

The expense guide was raised, but the bank emphasized that the increase is tied to performance and investment, not waste. Chris Gruseke said, “We're really talking about scale. And as you have a year that's going well and doing better, we're pretty — we run a meritocratic incentive plan. If people do better, we want them to get paid.” — Christopher Gruseke, President and Chief Banking Officer · 2026-07-23 Management clarified that the higher expense base is a byproduct of higher revenue, not a retreat from efficiency.

A block quote from the call crystallizes the philosophy:

We don't want to be in the business and won't be in the business of increasing expenses and decreasing our efficiency ratio. Just want to be clear, this is about scale.

The funding engine: deposits and the SBA

The deposit story is the quiet powerhouse. Core deposits grew 19% year-over-year, and the bank has cut brokered balances by $520 million — roughly 51% — since their peak in 2022. This reduction in wholesale funding is a structural improvement to the funding base, lowering interest expense and reducing sensitivity to market swings. Importantly, the growth is coming from banking relationships, not brokered money: “We're very relationship-driven. We don't bring on large quantities of new customers. We're really focused on deepening relationships with existing customers,” — Christopher Gruseke, President and Chief Banking Officer · 2026-07-23 said President Matt McNeill in response to a question about loan growth.

The SBA division continues to provide a valuable revenue diversifier, with gains on sale contributing $2.4 million in the quarter and $4.8 million in the first half — triple the prior year. The team is deliberately managing capacity, as McNeill explained: “For risk management purposes, we're going slow and steady. We don't anticipate raising our origination targets there to try to keep up with the other side of the business.” — Matthew McNeill, President and Chief Banking Officer · 2026-07-23 That measured approach keeps credit quality in check while still boosting noninterest income. The company's SBA division is now a meaningful contributor to fee income, and the bank expects it to remain so.

The deposit franchise is also becoming more rate-neutral. Management noted that 43% of loans are now floating rate, up from 23% at the end of 2024, which reduces the sensitivity to future rate moves. This positioning paid off in the quarter as the bank benefited from both asset repricing and liability savings.

Expenses up, but efficiency improves

The full-year noninterest expense guide was raised to $65–67 million from roughly $63 million, yet management was clear that this does not hurt the efficiency story. The second quarter efficiency ratio came in at 47.5%, comfortably better than the prior quarter's 49% (roughly), and the updated guidance implies a range of 50% to 52.8%, with the high end unchanged from before. As Courtney Sacchetti noted: “This new guidance keeps that high end. It's exactly 52.8% and lowers the best case scenario to 50%.” — Courtney Sacchetti, Executive Vice President and Chief Financial Officer · 2026-07-23 The bank is investing in talent and infrastructure, but it is doing so from a position of strength.

This is a marked change from the prior year, when management was still explaining a higher expense baseline. In the January 2026 call, Chris Gruseke had to justify the expense growth: “The people and processes. I mean, we've definitely added, you know, across the bank... And we want to have complete transparency as to what we're doing.” — Christopher R. Gruseke, Chief Executive Officer · 2026-01-29 Now, the story is the opposite: expenses are going up because revenue is going up faster, and the efficiency ratio is improving. The strong execution is translating into operating leverage that is now visible in the numbers.

A key metric to watch is the efficiency ratio, which has been on a steady downward path since the 2023 peak, reaching 31.3% on a trailing basis (including the recent quarterly improvement). The ratio has fallen from the mid-40s in 2023 to a recent 31.3%, a reflection of disciplined cost control. The bank's stated goal is to maintain this trajectory while funding growth, and the guidance suggests it can.

Outlook: More of the same, and that's good

Management raised full-year loan growth to 5–7% and net interest income to $115–117 million. The margin is expected to expand further into Q3, as there is still room on time deposit repricing. Feddie Strickland pressed on sustainability, and Chris Gruseke replied: “I think if we lay out the expenses and noninterest income and the revenue guidance that we've given, you can kind of get to the numbers pretty close. And yes, we're not surprised that they increased this quarter, and we see no reason for them to decrease unless the world changes.” — Christopher Gruseke, President and Chief Banking Officer · 2026-07-23 The market has taken notice: the stock is up 25% in the last 90 days, and the bank's favorable repricing dynamics are now a clear catalyst.

The bank is also playing into broader sector trends. While many regional banks are grappling with funding costs, Bankwell is actively cutting its wholesale funding and growing low-cost deposits — a strategy that is increasingly rare and increasingly rewarded. The core deposits growth of 19% year-over-year is a standout, and the progress on repaying brokered CD balances is a testament to the franchise's stickiness. As the bank moves toward a more rate-neutral balance sheet, it is better positioned to navigate whatever the macro environment throws at it.

In short, this was not a report that rested on one big item. It was a broad-based beat: margin, deposits, credit, and guidance all moved in the right direction. The raised expense guide might have raised eyebrows, but management made it clear that the cost is an investment in scale that should pay off in continued efficiency gains. Bankwell is proving that a regional bank can grow deposits and loans while simultaneously improving profitability — and that is a story worth watching.
