Moat

65 /100

Moderate moat

How hard OLD Second Bancorp's competitive advantage looks for rivals to wear away, judged from 10 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.

  • Returns on capital 16 / 20

    Net income has been a median 1.3% of total assets over 10 years.

  • Durability 16 / 20

    Net margin has been a median 26.4%; its worst year was 13.1%.

  • Discipline 10 / 20

    The diluted share count rose 78.4% over five years; stock-based pay has been a median 1.5% of revenue.

AI disruption exposure: Medium. In this industry, AI could change how the product is made or sold, without replacing the core asset. The score above includes a 5-point deduction for that exposure (70 before it).
