A number of analysts believe the buyer is BHP and that AZZ already have a portfolio of assets in the same basin line up to be purchased from the proceed of the current asset sale. The new purchase would be much bigger say 3 times of southern stars from smaller holders and low technical risk. this will avoid paying tax after asset sale. Some even put a wild estimate on these asset value in 2 years time at >600m. Consider the proximity of these analysts to AZZ management they must have got they hand on the information on AZZ plans ahead of the market.

That could explain why AZZ exits at the low ball 300m now just so they can grab and consolidate potential smaller assets in the area to develop and dump at higher price.
