Fun facts about NSTS Bancorp, Inc.

Quirks, history, and lore behind NSTS — the kind of stuff that makes a stock memorable.

1
The Basics
A community bank holding company · headquartered in Illinois · serving a local retail and commercial customer base · listed on Nasdaq.
2

A micro-cap institution with total assets well under $500 million — the kind of bank where the branch manager probably knows your name.
3
The History
Rooted in the northern Illinois / Lake County region, it has operated as a savings bank serving its community for decades before converting to a publicly traded holding company structure.

5
The Lore
It trades under a four-letter ticker that starts with 'N' — and with a market cap that fits comfortably in a small-town parking lot, it's about as under-the-radar as a public company gets.
6
The Giveaway
Based in Waukegan, Illinois, this tiny North Shore Community Bancorp-style thrift trades on Nasdaq under a ticker that is essentially just its initials twice.
