MOUNTAIN VIEW, Calif. (February 5, 2007) – Conceptus, Inc. (Nasdaq: CPTS), developer of the Essure® procedure, the first and only non-incisional permanent birth control method available, today updated financial guidance for the fourth quarter of 2006 and provided partial financial guidance for 2007.

Conceptus expects net sales for the fourth quarter of 2006 to be in the range of $12.8 million to $12.9 million. This compares with previous net sales guidance of approximately $12.0 million, which was issued on October 26, 2006. The Company expects net sales for the full year of 2006 to be in the range of $41.8 million to $41.9 million, compared with previous net sales guidance of approximately $41.0 million.

The net loss for the fourth quarter of 2006 is expected to be in the range of $4.0 million to $4.4 million, or $0.14 to $0.15 per share on an estimated 29.2 million shares outstanding. This net loss guidance includes stock-based compensation expense, which the Company expects to be in the range of $1.6 million to $1.8 million. This compares with previous net loss guidance of $3.1 million to $3.5 million, which excluded stock-based compensation expense. The Company expects the net loss for the full year of 2006 to be in the range of $18.6 million to $19.0 million, or $0.64 to $0.66 per share on an estimated 29.0 million shares outstanding. This net loss guidance range includes stock-based compensation expense, which the Company expects to be in the range of $6.1 million to $6.3 million. This compares with previous net loss guidance of $13.1 million to $13.5 million, which excluded stock-based compensation expense.

For 2007, Conceptus expects net sales for the full year to be in the range of $66 million to $68 million and for the first quarter to be in a range of $13.6 million to $14.0 million. The Company expects net loss for the full year of 2007 to be in the range of $8.1 million to $8.7 million and for the first quarter of 2007 to be in the range of $4.5 million to $4.8 million. This net loss guidance includes stock-based compensation expense, which the Company expects to be in the range of $6.3 million to $6.5 million for the full year of 2007 and $1.5 million to $1.7 million for the first quarter of 2007. This net loss guidance for the full year and the first quarter of 2007 excludes any effect of the proposed offering of convertible senior notes, announced today.

"We currently have about 86 sales representatives, and are continuing to increase our sales force as rapidly as we are able to identify and attract top talent,” commented Mark Sieczkarek, president and chief executive officer of Conceptus. “We are also accelerating our advertising programs in order to increase consumer awareness for the Essure system. We believe these important strategic initiatives will lead to continued gains in physician and patient adoption of the Essure system. We are also standing by our previously provided guidance that we expect to be profitable under GAAP by the fourth quarter of 2007."

The Company’s fourth quarter 2006 and full year 2006 financial guidance stated above is a preliminary estimate of the Company’s financials results for the completed fourth quarter and full year 2006 and does not present all information necessary for an understanding of the Company’s 2006 financial position and results of operations. Moreover, 2006 financial results are currently being audited by the Company’s independent registered public accounting firm. The Company’s completion of its 2006 financial statements, and the related audit of these financial statements, could result in actual results differing from the financial guidance stated above. The Company will provide more detailed financial guidance for 2007 when it releases financial results for the fourth quarter of 2006.
