Net Interest Margin Holds Near 3.8%

  • Across FY 2025, Amerant's reported net interest margin sat between 3.75% and 3.92% by quarter, with the trailing twelve month figure at 3.82% and the cost to income ratio at 69%.
  • What stands out for a bullish view is that this 3.82% net interest margin sits alongside trailing twelve month net income of US$52.4 million, which supports the idea of a bank that has shifted into profitability even though operating efficiency metrics like the 69% cost to income ratio show there is still room for improvement.
    • Quarterly net interest margin moved from 3.75% in Q1 2025 to 3.81% in Q2 and 3.92% in Q3, before results were summarized for Q4, suggesting the earnings base is closely tied to how that spread is managed.
    • The trailing twelve month revenue of US$394.2 million paired with US$52.4 million of net income shows that, while Amerant is profitable, earnings are a relatively modest slice of total revenue, which matters for how durable any bullish case might be.

Credit Quality Signal From US$171.4 Million Of Non Performing Loans

  • At the end of the latest trailing twelve month period, non performing loans were reported at US$171.4 million, with commentary noting that the allowance for bad loans covers 76% of those exposures.
  • Critics highlight that a 76% allowance for bad loans is relatively low coverage, and the US$171.4 million of non performing loans gives that concern real weight because any increase in credit losses would flow directly through to earnings and capital.
    • Within FY 2025, reported non performing loans moved between US$82.5 million and US$124.3 million by quarter before ending at the US$171.4 million trailing twelve month figure, so credit quality is clearly a key line item to watch rather than a side issue.
    • Against this backdrop, the bank's recent profitability, with US$52.4 million of trailing twelve month net income, sits alongside a balance sheet that still carries a sizeable pool of problem loans and a coverage level below 100%, which is exactly what bearish investors tend to focus on.

Profitable Year With 1.26 US$ TTM EPS

  • For the trailing twelve months, Amerant reported basic EPS of US$1.26 on revenue of US$394.2 million, compared with earlier trailing periods that included EPS losses such as US$0.44 loss per share in the year to Q4 2024.
  • Bulls argue that the move from prior losses to US$1.26 of trailing twelve month EPS supports the view of projected earnings growth around 34% per year, yet the path within FY 2025, with quarterly EPS varying from US$0.28 to US$0.55 then down to US$0.07, shows that the earnings profile has been uneven even as the full year ends in profit.
    • Quarter by quarter, net income excluding extra items was US$11.96 million in Q1 2025, US$23.00 million in Q2, US$14.76 million in Q3 and US$2.70 million in Q4, which means a lot of the trailing twelve month profit was generated earlier in the year rather than in the most recent quarter.
    • That pattern aligns with the data point that Amerant became profitable over the last year after several years of negative average earnings, so the bullish thesis rests on whether this new US$52.4 million profit level can be sustained or improved upon from here.
