It really looks to me that the Spanish want to take out the whole company.
Either they will keep buying on market and hope to steal it for around $22 or they will make a bid to bring it to a head quickly.
They already hold around 75%. Iif they choose the slow route and Cimic buys back 10% on market, the Spanish will hold upwards of 84%. At a premium of, say, 25% on today's price (say around $25), it would only cost $1.3bn to buy the whole lot. They could probably sell Theiss for a lot more than that when the market recovers and they would have a purer construction company.
I may be reading too much into it, but that is what i am currently seeing.
