01

How does the company make money?

Marathon Bancorp is the publicly traded parent of a small regional bank in Wisconsin. It accepts deposits and primarily makes real estate loans.

02

What supports the business?

Net interest income has increased significantly; the bank has a high reported capital ratio and, so far, few nonperforming loans.

03

What could improve?

More good loans and stable deposit costs could improve returns on existing equity.

04

How is the stock price assessed?

14.45 USDReviewed share price dated

This assessment refers to the analysis and its quoted price shown here. It is not a live quote or a personal recommendation to buy.

14.45 USD initially appear inexpensive relative to book value. However, given the still-weak earning power, the price is above my conservative reference point of 12.75 USD.

05

What is the main risk?

A small bank can be significantly affected by even a few real estate loan defaults, more expensive deposits, or limited liquidity in its shares.

06

What is the overall assessment?

Marathon Bancorp has improved profitability. Given its still-low earnings power, the discount to book value is not enough to provide a clear buy signal.
