Medco (MHS Quote) plunged 14% early Tuesday after the big mail-order pharmacy warned that 2006 earnings might not please Wall Street. The company posted a 33% earnings gain for its third quarter, as revenue hit $9.3 billion. Third-quarter profits of 62 cents a share came in 2 cents ahead of the consensus estimate. But the company guided to 2006 earnings of between $2.52 and $2.64. Analysts were expecting Medco to report operating profits of $2.38 in 2005 and $2.79 in 2006. Medco dropped $7.50 to $49. "Our performance in improving sales, achieving record levels of retention and expansion into Medicare and specialty pharmacy makes us confident that we will achieve our objective of recording double-digit earnings growth in 2005," CEO David Snow said, "and to achieve continued strong growth in 2006."
