I did some reseach on AHE a few months ago and liked alot of it's business plus this earnings result was nothing short of stellar It's PE is now less than what it has averaged during the current ASX bull run.
As a non-holder, my guess for the reasons is similar to why I didn't buy. It's a cyclical industry where the 3-4 years of impressive growth may mean it's head to the other side of the circle, and the business does have plenty of debt which holds it's PE down.
Fantastic recent history though.
