Bridgewater Bancshares (BWB) Q4 2025 earnings review
NIM Accelerates, But Credit Quality Hits a Wall
Bridgewater delivered outstanding operational performance in Q4 2025, with Net Income up 15% sequentially to $13.3 million ($0.43 EPS). The Net Interest Margin (NIM) expanded 12 basis points to 2.75%, driven by accelerating declines in deposit costs (down 22 bps QoQ to 2.97%). This operational momentum was severely overshadowed by a dramatic reversal in credit quality: Nonperforming Assets (NPAs) soared 120% linked-quarter to $22.0 million (0.41% of total assets), reversing the bank's long-standing 'superb' asset quality narrative.
🐂 Bull Case
NIM expanded 12 basis points to 2.75%, showing the balance sheet is successfully capitalizing on lower funding costs. The Adjusted Efficiency Ratio hit a new low of 50.7%, demonstrating strong operational leverage.
The cost of total deposits collapsed 22 basis points QoQ to 2.97%. Noninterest-bearing deposits grew $100 million, or 48% annualized, significantly enhancing the quality and stability of the funding base.
🐻 Bear Case
Nonperforming Assets (NPAs) spiked 120% linked-quarter to 0.41% of total assets, their highest level in years. Net charge-offs also jumped to 0.11% annualized, signaling a material deterioration in the loan book.
Loans warranting Watch/Special Mention risk ratings increased to $47.8 million (up from $40.6M QoQ), indicating a growing backlog of problem loans that have yet to hit NPA status.
⚖️ Verdict: ⚪
Neutral/Cautious. The NIM expansion and efficiency gains confirm excellent operational execution, positioning BWB to grow earnings significantly. However, the sudden and substantial reversal in credit quality, evidenced by the NPA spike, demands caution until management can prove the issue is isolated and not systemic.
Key Themes
The Credit Quality Reversal is Severe
The increase in NPAs from 0.19% to 0.41% of total assets is a massive reversal that challenges the bank’s previously 'superb' credit reputation. The Q3 narrative cited single-loan issues, but the magnitude of the Q4 spike suggests the isolated issues may be multiplying or worsening. The Allowance for Credit Losses (ACL) to Total Loans dipped slightly to 1.31%, despite the credit migration, indicating a potential lag in reserve building relative to risk increase.
Funding Costs Fall Dramatically, Driving NIM
The successful execution of liability management accelerated NIM expansion. The Cost of Total Deposits dropped 22 basis points QoQ to 2.97% (Accelerating Decline). This was fueled by a positive mix shift: brokered deposits declined, and noninterest-bearing transaction deposits grew substantially (up $100 million linked-quarter). This structural improvement provides a long-term earnings tailwind.
Balanced Loan and Core Deposit Growth
Gross loans increased by $95.0 million, achieving an 8.9% annualized growth rate (Accelerating slightly from Q3 6.6%), positioning the Loan-to-Deposit ratio at 99.7%—firmly within the target 95%-105% range. Crucially, core deposits grew at a corresponding 8.8% annualized rate, maintaining the profitable funding alignment that management targets.
Acquisition Integration Delivering Efficiency
The Adjusted Efficiency Ratio dropped significantly to 50.7% (Accelerating Improvement) following the successful Q3 system conversion of the First Minnetonka City Bank (FMCB) acquisition. Merger-related expenses decreased to $346,000 in Q4 from $530,000 in Q3, suggesting expense normalization is taking hold as the previously redundant costs are phased out, confirming management's expense control guidance.
Noninterest Income Volatility
Noninterest income surged to $3.1 million (up 52.7% QoQ), primarily driven by high swap fees and letter of credit fees. Management previously noted that swap fees are ‘inherently lumpy’ and unpredictable. Relying on this volatility for future revenue growth is risky, especially as the Q2 spike was also driven by one-time gains.
Affordable Housing and Construction Lead Loan Growth
Loan growth continues to be strong in targeted verticals. Construction and Land Development loans showed exceptional linked-quarter growth (up 35% to $216 million), supported by projects funding from prior quarters. Multifamily remains the largest portfolio segment ($1.59B) and is boosted by the national affordable housing vertical, which management cited as growing 27% annualized YTD in Q3.
Other KPIs
Adjusted EPS grew 13% sequentially and 63% YoY ($0.27 in 24Q4). This highlights the operational success in expanding margins and controlling non-core expenses, providing strong momentum into FY26 despite the credit headwinds.
TBV per share grew 16.5% annualized QoQ and 15.3% YoY. This marks a strong recovery following the acquisition-related dip in 24Q4, demonstrating that solid earnings retention and declining accumulated other comprehensive loss (AOCI) are successfully building shareholder value.
While Noninterest Expense increased only slightly QoQ ($20.2M vs $20.0M), it remains significantly elevated YoY (up 20%), primarily due to the FMCB acquisition and associated costs. However, the efficiency improvement confirms that revenue growth is finally outpacing expense growth (Operating Leverage).
Guidance
Decelerating from 11.4% actual growth in FY25. This guidance is consistent with prior expectations, emphasizing a focus on profitable, core deposit-aligned growth rather than maximizing volume, reflecting cautiousness about the macroeconomic environment.
Accelerating/Confirmed. The substantial NIM expansion in Q4 (to 2.75%) puts the bank well on track for the 3.00% target, which assumes continued asset repricing and 50 bps of Fed rate cuts in 2026 to further reduce funding costs.
N/A. Management did not provide specific forward guidance on credit metrics but noted that Nonperforming Assets are defined as strong despite the shock. Given the 0.41% result in Q4, the market expects NPAs to stabilize or decline from this elevated level.
Key Questions
Source of NPA Spike
The NPA ratio spiked from 0.19% to 0.41% this quarter. Can management provide specific details on the assets that migrated to nonaccrual? Is the increase driven by existing stressed assets (CBD office/multifamily) or is this related to new stress in Construction or C&I?
Adequacy of Allowance for Credit Losses (ACL)
Given the increase in both NPAs and Watch/Special Mention loans, is the current ACL/Total Loans ratio of 1.31% sufficient? What would trigger a substantial increase in the provisioning rate going forward?
Sustainability of Deposit Cost Decline
The cost of deposits fell dramatically to 2.97%. How much further can funding costs decline without significant Fed rate cuts, and what percentage of the remaining deposit base is highly rate-sensitive?
