Ann: Orocobre and Galaxy Merger - Announcement, page-561

"Galaxy shareholders will receive 0.569 Orocobre shares for each Galaxy share held at the Scheme record date. Upon implementation of the Scheme, Orocobre shareholders will own 54.3% of the fully diluted share capital of the combined entity and Galaxy shareholders will own the remaining 45.7%"

That's all you need to know. Both companies benefit from this merger due to synergies, diversification, cheaper financing costs etc.. The stock market is already pricing this in, although I think the stocks will go even higher in the near future.
