PPIH I don't think the data centers have much to do with it going up recently, its just strong earnings numbers, they are doing a great job with their piping and cooling systems in the Mid-East. PPIH gets big contracts several times per year. The backlog is very strong right now on a historical basis, basically near all time highs. I don't think you can annualize Q1, taxes were low and margins are lumpy.. seemed like a very high margin quarter, I believe the prior quarter was a low margin quarter.
Main point is I think the way you are thinking about the backlog is wrong. Again, they usually announce very large orders like twice per year. But PPIH sure looks aggressively valued. I'd need a serious pullback to add anything.
