Columbia Financial Q1 2026: Higher EPS, Higher Yields, and a Merger Roadmap

Quarter at a glance

Columbia Financial, Inc. (NASDAQ: CLBK) punched through the first quarter of 2026 with a net income of $13.1 million and earnings per share (EPS) of $0.13 on a basic and diluted basis. That compares to net income of $8.9 million and EPS of $0.09 for the quarter ended March 31, 2025. In the language of bankers for whom every basis point is a heartbeat, that’s a meaningful step up year over year, even before the merger drama and conversion plans land fully.

The company frames the narrative around a higher net interest income, underpinned by both increased interest income and a reduction in interest expense on deposits and borrowings, a combination you’d label as “progress in a rising-rate world” if you didn’t fear jinxing it with too tidy a phrase.

Financial highlights that matter

• Net interest income: $60.4 million for the quarter ended March 31, 2026, up by $10.1 million, or 20.0% from $50.3 million a year earlier.
• The increase was led by a $6.7 million rise in interest income and a $3.4 million decrease in interest expense on deposits and borrowings.
• Net interest margin (NIM): Not a single number, but the story includes a 12-basis-point rise in the average loan yield to 5.01% (from 4.89% year over year).
• Average yield on securities: 3.38% for the quarter, down ~7 bps versus the prior year’s level (the narrative notes securities yields softened while asset balances rose).
• Average yield on other interest-earning assets: down to 4.78%, reflecting a broader shift in asset yields during the period described.
• Total interest expense: $58.5 million for Q1 2026, down $3.4 million or 5.4% from Q1 2025.
• Loan recoveries vs. charge-offs: net recoveries of $604,000 for Q1 2026, versus net loan charge-offs of $857,000 in Q1 2025.

Operational context: margins, volumes, and the rate backdrop

The press release digs into how shifts in the rate environment and loan mix influenced results. Net interest income benefited from higher yields on loans and a larger average loan balance, while a reduction in deposit costs helped compress the expense side. The document notes a 75 basis point rate decline in 2025 that mattered for funding costs and pressurized yields on new deposits, but it also emphasizes that yields on earning assets remained relatively stable as existing loans repriced. In other words: the bank rode a rate wave with some skill and some luck.

Strategic moves in motion

Beyond the numbers, Columbia Financial signaled a big strategic fork in the road. The company announced its intention to undertake a second-step conversion offering and a significant merger with Northfield Bancorp. Management frames these moves as a way to enter new geographic markets in the New York metro area, bolster the deposit base at a lower cost, and secure capital for growth. Regulatory approvals and stockholder/member approvals are prerequisites, so the path from “announced” to “in progress” remains a classic bank-stage cliffhanger.

What this might portend for CLBK and sector peers

From a narrative standpoint, the quarter reinforces the recurring theme in mid-cap banks: modest asset growth paired with margin discipline can translate into meaningful earnings gains, especially when strategic transactions unlock scale and efficiency. The dual engine of higher net interest income and lower deposit costs presents a tangible upside path, but the real liquidity/credit story will hinge on the Northfield integration and the timing of the second-step conversion. For peers—regional banks with similar growth ambitions—the story is a reminder to watch debt funding costs, the pace of loan growth, and the trajectory of non-interest expenses as banks chase efficiency in a competitive deposit landscape. Analysts will undoubtedly compare EPS surprises (or the lack thereof) against EPS consensus once broader guidance and consensus estimates surface, with revenue forecast models baked around net interest income and fee-based streams rather than a single line item.

Analyst questions to watch

1. What is the cadence for the Northfield Bancorp merger—closing timeline, integration milestones, and expected cost savings?
2. How will the second-step conversion impact capital levels, liquidity, and the firm’s ability to fund growth without compromising credit quality?
3. Will the EPS trajectory translate into a favorable earnings surprise relative to expected EPS consensus once analysts publish estimates?
4. What are the forward-looking revenue forecast implications from the merger and conversion in a backdrop of rate normalization or volatility?

Bottom line

Columbia Financial’s Q1 2026 results underscore a bank that leveraged rising loan yields and a shrinking deposit cost base to lift net interest income and EPS to a higher plane. The strategic backdrop—merger with Northfield Bancorp and a second-step conversion—adds a layer of optionality that could amplify the growth profile if execution meets promise. For CLBK and its regional peers, the mid-2020s playbook remains: win on net interest income, control costs, and navigate the integration curve of a major merger while keeping an eye on how EPS consensus and revenue forecasts evolve in a dynamic rate environment.
