Ames National Corporation (ATLO) Income Statement

The climb in NII from roughly $10.9M to $17.0M across ten quarters suggests balance sheet expansion and improved asset repricing are contributing to earnings recovery. Year-over-year growth has stayed in the high teens to mid-20 percent range for most recent quarters, which appears to reflect loan volume gains rather than a one-time rate tailwind. Investors should monitor whether deposit funding costs keep pace, since sustained NII growth depends on the spread between asset yields and deposit betas.

The reported NIM improvement from about 0.5% to 0.8% indicates that asset yields have been repricing faster than funding costs, though the absolute level is low relative to typical regional bank benchmarks. The flat reading across 2026Q2 and 2026Q3 suggests the margin expansion may be maturing. Further gains would likely require either deposit cost discipline or a mix shift toward higher-yielding assets, which warrants further investigation.

A drop of roughly 25 percentage points in the efficiency ratio points to meaningful operating leverage, as revenue grew faster than the cost base. The most recent quarter at 55.0% sits at a level that suggests improving cost discipline. However, the trend may partly reflect a rising revenue base rather than purely lower expenses, so investors should check whether expense growth remains contained as the bank scales.

Provision volatility, including two quarters with reserve releases, suggests credit quality has been stable on the reported figures. The low current provision of $66K relative to a $27.1M revenue base implies limited near-term credit cost pressure. That said, provisions on a small loan book can swing with individual credits, and the absence of a clear cyclical trend means investors should monitor reserve adequacy if economic conditions weaken.

A fee share in the mid-teens points to a balance sheet weighted toward net interest income, which increases sensitivity to rate cycles and margin compression. Non-interest income has not grown as quickly as NII, so the earnings mix appears to be becoming more concentrated in lending spreads. Investors may want to assess how much of the fee base is recurring versus transactional before judging diversification benefits.
