iii. Is this a good business?

Share count is up 21% over 5 years — owners have been diluted. Worth asking what they got for it. Total debt has fallen 52% — deleveraging.

iv. What it’s worth — engine v0.1.0

The 3 estimate methods that apply put fair value between $7.51 and $249.87 a share. They rest on different assumptions, so where they diverge is the story; the Graham Number is a stricter floor, not a target.
