provided and post a new message if I have remaining questions.

Not quite. If they don't overlap, then yes, they are
different; but if they do overlap, the two intercepts
may still be significantly different at an alpha of 5%.

See whether their confidence intervals overlap...

Dear Stata List,
I have computed two linear regressions and would like to compare
the computed intercepts statistically. Is there a command or
command process that can achieve this? Thank you for your
assistance.
