LONDON — Peabody Energy said on Wednesday that it had acquired more than 90 percent of Macarthur Coal of Australia. The announcement allows Peabody, an American coal company, to require Macarthur’s remaining shareholders, including the South Korean steel maker Posco, to sell their stakes.

Peabody is also increasing its offer for Macarthur by $100 million, to almost $5 billion, as part of its earlier terms. The company had said it would raise its bid to $16.52 a share from $16.27 a share if it gained a 90 percent stake in Macarthur.
