Bank First Q1 Earnings: A 33% Surge in Assets
💡 Puntos Clave
Bank First's acquisition of Centre has successfully driven significant growth in assets, loans, and deposits, though core profitability metrics show mixed results.
What Happened in Bank First's Q1 2026?
Bank First announced its first quarter 2026 financial results, which were overwhelmingly shaped by its recent acquisition of Centre. The deal, which closed during the quarter, added approximately $1.48 billion in assets, boosting Bank First's total assets by 33% to $6.07 billion. This transformative move instantly reshaped the bank's balance sheet and operating scale.
The bank's net interest margin (NIM), a key measure of lending profitability, was 3.96% for the quarter. This represents a slight decline from 4.01% in the prior quarter but a solid improvement from 3.65% in the same quarter last year. A portion of this NIM was supported by one-time accounting gains from the acquisition.
On the balance sheet, the acquisition's impact is clear. The loan portfolio grew by $911 million to $4.52 billion, with nearly all of that growth attributable to the loans acquired from Centre. Similarly, total deposits surged by $1.39 billion to $5.09 billion, with Centre contributing $1.38 billion of that increase.
The composition of the bank's funding improved, with noninterest-bearing demand deposits—a cheap source of funds—rising to 29.4% of total deposits, up from 27.1% at the end of 2025. The investment portfolio also ballooned, largely due to the $333 million in securities that came over from Centre.
Why These Earnings Matter for Investors
For investors, this quarter demonstrates Bank First's successful execution of a growth-by-acquisition strategy. The seamless integration of Centre has meaningfully increased the bank's size and market presence almost overnight, which can lead to greater operational efficiency and competitive strength over the long term.
The growth in core, low-cost deposits is a particularly positive sign. A higher share of noninterest-bearing deposits reduces the bank's funding costs, which can help protect its net interest margin in a future environment where interest rates might fall.
However, the slight quarter-over-quarter dip in the core net interest margin (excluding acquisition accounting benefits) warrants attention. It suggests that integrating the new loan portfolio and managing the larger balance sheet is applying some pressure on profitability in the near term, which is a common challenge post-acquisition.
Bobby Insight

Bank First is a solid hold as it digests a transformative acquisition.
The strategic benefits of the Centre deal—33% asset growth and a stronger deposit base—are clear and positive. However, the slight compression in the core net interest margin indicates integration costs and competitive pressures are present, justifying a neutral stance until profitability trends become clearer.
