The thesis, from the filings

MIAMI INTERNATIONAL HOLDINGS, INC. earns about 9% on invested capital, barely covering its ~9% cost of capital, but has diluted owners by 24% over 3 years — worth asking whether the growth reaches owners. The estimate methods put fair value between $27.69 and $29.51 a share.Whether it’s worth owning at today’s price is the last question — and yours to answer, below.

iii. Is this a good business?

FY23 -2%FY24 40%FY25 -10%

It earned about 9% on invested capital against a ~9% cost of capital — roughly what it costs to fund the business, so the numbers show no clear edge.

Management signal · capital allocation
+24% shares · 3y

Share count is up 24% over 3 years — owners have been diluted. Worth asking what they got for it. Total debt has fallen 96% — deleveraging.
