Zimmer Holdings ( ZMH) said Tuesday that it will offer to acquire Centerpulse, a Swiss medical device maker, for $3.22 billion in cash and stock.

In 2002, Zimmer recorded worldwide revenue of $1.37 billion. On Tuesday, Zimmer estimated its second-quarter earnings would be 39 or 40 cents a share, excluding the costs of the proposed merger. Last year it reported second-quarter earnings of 34 cents per share. Shares of Zimmer were at $44 in midday trading, down $4.28, or 9%.
