ConnectOne Bancorp (CNOB) Q2 2025: Deposit Growth Surges 17% Annualized Post-Merger, Margin Expansion in Focus

2025-07-29 | By EarningsIQ Research

ConnectOne Bancorp’s Q2 marked a transformative quarter, as the First of Long Island Bank merger lifted deposit growth and improved funding mix, while cost synergies and disciplined integration efforts set the stage for margin expansion and higher returns into 2026. Management’s focus on client retention, deposit composition, and conservative credit provisioning signals a deliberate, risk-managed approach to scale—with early results suggesting upside to both profitability and capital flexibility. Investors should watch margin trajectory and loan pipeline execution as the new platform beds in.

Summary

• Merger Integration Delivers Funding Upside: Core deposit growth and DDA mix exceeded expectations, supporting balance sheet strength post-acquisition.
• Margin and Return Levers Activate: Cost saves, improved deposit mix, and purchase accounting accretion drive near-term margin and ROE expansion.
• Capital Flexibility Emerges: Strong capital ratios and earnings accretion position CNOB for potential buybacks and continued organic growth.

Performance Analysis

Q2 2025 was defined by the successful closing and integration of the First of Long Island Bank merger, which propelled ConnectOne’s assets to nearly $14 billion and deposits to $11.3 billion. Core deposit growth was a standout, with non-interest-bearing demand deposits (DDA) rising above 21% of total deposits (up from 18% at year-end), and core balances increasing by over $500 million annualized—17% growth—despite a reduction in brokered and wholesale funding. The loan-to-deposit ratio improved to 99%, providing funding headroom and lowering reliance on higher-cost borrowings.

Margin dynamics and credit provisioning were key themes: Net interest margin is expected to expand by 10 basis points in each of Q3 and Q4, according to management, with further upside into 2026 as cost saves materialize and deposit mix improves. The quarter’s $35.7 million provision for credit losses reflected both a required day-one charge from the merger and a conservative approach to longer-duration acquired loans, particularly in regulated multifamily. Non-performing asset ratios improved sharply, and the allowance for credit losses rose to 1.4% of loans—primarily due to purchase accounting marks, not underlying credit deterioration.

• Deposit Mix Shift: DDA balances now exceed 21% of deposits, supporting lower-cost funding and margin expansion.
• Cost Synergy Realization: Merger-related charges are tracking below the $52 million target, with $40 million recognized and cost saves on pace for 35% efficiency targets.
• Loan Growth Moderation: Organic loan balances were flat as elevated payoffs offset strong origination demand, though pipelines remain healthy with weighted average yields of 6.77%.

With the merger now closed and systems conversion completed in under 30 days, ConnectOne enters the second half with a unified brand, expanded footprint, and strategic focus on margin, credit, and capital deployment levers.

Executive Commentary

Strategic Positioning

1. Merger Execution and Integration Discipline

ConnectOne’s approach to M&A emphasizes client retention, operational continuity, and rapid systems integration. The First of Long Island Bank transaction was legally closed and operationally integrated within a month, with “excellent client and deposit retention” and no material disruption. This sets a foundation for future dealmaking and signals operational maturity at higher asset thresholds.

2. Funding and Deposit Strategy

Deposit gathering and funding mix are now clear competitive advantages. The company’s ability to grow DDA balances and reduce brokered and wholesale funding post-merger directly supports net interest margin and provides flexibility as interest rates shift. Management’s focus on relationship-based banking and new market traction, especially on Long Island, underpins further core deposit growth potential.

3. Margin and Return Enhancement

Margin expansion is a central lever, with management projecting a 20 basis point NIM increase in the second half of 2025 and further upside into 2026. Purchase accounting accretion, cost saves, and improved deposit mix all contribute, while expense discipline and merger synergies are expected to keep quarterly expenses in the $55–57 million range. Management reiterates comfort with a 1.2% return on assets and 15% return on tangible common equity as the new base case for 2026.

4. Credit and Capital Management

Conservative provisioning and strong capital ratios position CNOB for both risk management and capital deployment flexibility. The company’s allowance for credit losses rose due to purchase accounting, not asset quality deterioration. Capital ratios remain robust (Bancorp tangible common equity at 8.1%, bank CET1 above 12%), providing optionality for buybacks or further organic growth as integration matures.

Key Considerations

This quarter marks a structural shift for ConnectOne, as the company absorbs its largest acquisition and repositions for scale, margin, and capital flexibility. Investors should monitor how well the company sustains deposit growth, manages expense discipline, and converts its loan pipeline into profitable asset growth amid ongoing payoffs.

Key Considerations:

• Deposit Franchise Strength: The surge in core deposits and DDA mix provides a durable funding advantage as rate cycles evolve.
• Margin Expansion Path: Purchase accounting, funding mix, and cost saves are set to drive NIM and ROE higher, with management projecting 20 basis points of NIM uplift in 2025.
• Expense Discipline and Synergy Capture: Integration costs are trending below plan, and quarterly expense run rates appear well-controlled relative to revenue growth.
• Loan Growth and Pipeline Management: While origination demand is strong, elevated payoffs have muted loan growth, making pipeline conversion a key watchpoint.
• Capital Deployment Optionality: Robust capital ratios and earnings accretion may enable share repurchases or further expansion if growth opportunities persist.

Risks

Integration risk remains as the company absorbs its largest-ever merger, with the potential for unforeseen operational or client attrition issues in coming quarters. Elevated credit provisioning tied to acquired portfolios, especially regulated multifamily loans, could pressure results if credit conditions deteriorate. Loan growth faces headwinds from ongoing payoffs, and further margin expansion depends on successful synergy realization and sustained deposit momentum. Regulatory changes to CECL provisioning may also affect future earnings volatility.

Forward Outlook

For Q3 and Q4 2025, ConnectOne guided to:

• Net interest margin expansion of 10 basis points per quarter, assuming one rate cut in 2025
• Quarterly expenses in the $55 million range for 2025, rising modestly to $56–57 million in 2026

For full-year 2026, management reiterated:

• Return on assets of 1.2% and return on tangible common equity of 15% as achievable targets

Management highlighted several factors that will shape outcomes:

• Continued focus on deposit growth and funding mix to drive margin
• Loan growth dependent on origination strength and payoff trends

Takeaways

ConnectOne emerges from its largest merger with a stronger funding base, margin expansion levers, and robust capital position. The company’s disciplined integration and conservative provisioning provide a cushion against near-term credit or operational risks, while upside remains from further cost saves and capital deployment flexibility.

• Funding Upside: Core deposit and DDA growth post-merger support both margin and growth capacity, setting CNOB apart from peers facing funding pressures.
• Margin and Return Expansion: Management’s clear path to higher NIM and ROE is underpinned by synergy realization, improved funding mix, and prudent credit management.
• Execution Watchpoint: The next phase hinges on converting loan pipeline into balance sheet growth and sustaining expense discipline as the new platform stabilizes.

Conclusion

ConnectOne’s Q2 2025 demonstrates a well-executed merger integration, robust deposit growth, and a clear trajectory for margin and return improvement. The company’s focus on operational discipline and capital flexibility positions it favorably for the next phase of growth, though sustained loan origination and continued synergy capture will be critical to delivering on its upgraded profitability targets.

Industry Read-Through

ConnectOne’s experience underscores the importance of core deposit growth and disciplined integration in regional bank M&A, especially as regulatory thresholds are crossed. The ability to grow DDA balances and reduce reliance on wholesale funding is a critical differentiator in the current rate environment. Purchase accounting transparency and conservative credit provisioning set a standard for post-merger risk management, while the focus on cost saves and capital deployment will resonate across the sector as banks seek to scale profitably amid ongoing margin pressures and evolving regulatory requirements.
