WESTAMERICA BANCORPORATION

WABCdata completeness 88%18 fiscal years on file
The thesis, from the filings

WESTAMERICA BANCORPORATION earns about 21% on invested capital, far above its ~9% cost of capital, and has bought back 4% of its shares over 5 years — the marks of a durable business run for its owners. The estimate methods put fair value between $47.53 and $137.45 a share. Whether it’s worth owning at today’s price is the last question — and yours to answer, below.

10 shares is a claim on $363.6 of net worth that earned you $45.25 and generated $46.6 of cash last year, against $53.48 of debt.

iii. Is this a good business?
Moat signal · return on invested capital
21% avg · 5y
FY21 9%FY22 19%FY23 20%FY24 32%FY25 26%

It earned about 21% on invested capital, year after year, against a ~9% cost of capital — the footprint of real pricing power. Competition usually drags returns like this back down; here it hasn't.

seeing a moat in the numbers →
Management signal · capital allocation
−4% shares · 5y

Share count is down 4% over 5 years — management has been buying back stock, quietly handing owners a bigger slice. Total debt has held roughly steady.

Signals, not verdicts — read from the filings above. Numbers don’t prove a moat; they show its footprint. You decide.

iv. What it’s worth — engine v0.6.0

The 3 estimate methods that apply put fair value between $47.53 and $137.45 a share. They rest on different assumptions, so where they diverge is the story; the Graham Number is a conservative ceiling on what a defensive investor should pay, not a target.
