It was certainly a big-time bet: Chinalco agreed to invest a whopping $19.5 billion in Rio Tinto (NYSE: RTP), which is the #3 ore miner. However, over the past couple months, there was some doubt as to whether this transaction would come to fruition.Well, this week, we got an answer. That is, Rio decided to dump Chinalco and instead form a joint venture (JV) with BHP Billiton (NYSE: BHP), which is the #2 player in the global ore industry (keep in mind that both firms had a buyout deal that blew up last year).
Now, the JV has lots of merit. For example, there will be huge cost synergies, which could amount to more than $10 billion.
As a result, Rio Tinto plans to raise $15.2 billion in an equity offering, which will deeply dilute shareholders. Oh, and BHP will pump $5.8 billion into the JV.
But, as is the case with mega deals, there was a big dose of politics. No doubt, Rio Tinto is a major strategic asset for Australia. So, selling a massive stake to a Chinese operation was not particularly favorable. And, it definitely helped that the global credit markets started to open up over the past few months, making it easier to access capital and devise creative alternatives.
