Conceptus^® Reports First Quarter Financial Results

Affirms 2011 Financial Guidance

Conference Call Begins at 4:30 p.m. Eastern Time Today

MOUNTAIN VIEW, Calif., May 10, 2011 – Conceptus, Inc. (Nasdaq: CPTS), developer of the Essure^® procedure, the most effective non-surgical permanent birth control method available, today reported financial results for the three months ended March 31, 2011.

Net sales for the first quarter of 2011 were $26.6 million, compared with net sales of $33.4 million for the first quarter of 2010. The net loss for the first quarter of 2011 was $2.9 million, or ($0.09) per share. This compares with a net loss for the first quarter of 2010 of $2.4 million, or ($0.08) per share.

Adjusted earnings before interest, taxes, depreciation, amortization and stock-based compensation (“adjusted EBITDA”) for the first quarter of 2011 were $0.1 million, compared with adjusted EBITDA for the first quarter of 2010 of $2.9 million.

“Macroeconomic pressures, challenging insurance trends, competitive trialing and our planned strategic focus were the primary factors that impacted our sales this quarter, resulting in an unfavorable comparison to a strong sales performance in last year’s first quarter,” said Mark Sieczkarek, president and chief executive officer of Conceptus. “Continued unemployment, the increasing loss of insurance coverage, the shifting of more health insurance costs to employees, and the annual resetting of insurance deductibles all affect consumers’ ability to pay for non-urgent procedures such as Essure.”

“We executed well on our planned strategic initiatives to launch the promotion of the GYNECARE THERMACHOICE® III endometrial ablation product and defend our physician accounts against competitive trialing. This progress, however, came at the expense of our growing the hysteroscopic sterilization market during the first quarter of 2011. We will now balance these strategic advances and place a stronger focus on growing the market for the remainder of the year. We will work to increase sales force productivity, expand physician penetration and utilization of the Essure procedure and drive greater patient adoption through integrated marketing,” said Sieczkarek. “We expect our efforts in these areas to translate into stronger financial results as we continue to stay the course and execute our strategic plan for long-term growth.”

First Quarter of 2011 Highlights

Domestic sales were $18.9 million for the first quarter of 2011, compared with $25.4 million for the first quarter of 2010 and $28.6 million for the fourth quarter of 2010. The year-over-year decrease primarily reflects continuing macroeconomic pressures that have contributed to reductions in patient visits to OB/GYN offices, as well as ongoing competitive product trialing. The quarter-to-quarter reduction also includes the normal seasonality of the business as insurance deductibles reset annually for most insured families. International sales were $7.7 million for the first quarter of 2011, compared with $8.0 million for the first quarter of 2010 and the fourth quarter of 2010. The year-over-year and sequential decrease was due to a decline in shipments to our international distributors offset by an increase in direct sales in France.

During the first quarter of 2011 in the U.S., the Company entered approximately 340 physicians into preceptorship, certified approximately 189 physicians and transitioned approximately 89 physicians to performing procedures in the office setting. To date, approximately 12,870 physicians have performed the Essure procedure.

Gross profit for the first quarter of 2011 was $21.4 million or 80.4% of net sales, compared with $27.0 million or 80.8% of net sales for the first quarter of 2010. The year-over-year decrease in gross profit margin was primarily due to a higher percentage of lower-margin international sales in the first quarter of 2011. Total operating expenses for the first quarter of 2011 were $25.1 million, a decrease of 9.6% from $27.7 million for the first quarter of 2010, which primarily reflected lower marketing expenses.

Cash, cash equivalents and investments were $91.7 million as of March 31, 2011, an increase of $0.8 million from December 31, 2010. The Company generated $3.7 million in cash from operations during the first quarter of 2011.

Financial Guidance

Conceptus affirmed full year 2011 financial guidance as follows:

“As communicated previously, we do not expect the first half of 2011 to compare favorably with the first half of 2010 given the macroeconomic factors, competitive trialing and our near-term focus on launching the global endometrial ablation business. We anticipate stronger results in the second half of 2011, but still expect macroeconomic headwinds and an uncertain impact from insurance trends in the second quarter,” said Sieczkarek.

Use of Non-GAAP Financial Measures

The Company has supplemented its GAAP net loss with a non-GAAP measure of adjusted earnings before interest, taxes, depreciation, amortization and stock-based compensation (“adjusted EBITDA”). Management believes that this non-GAAP financial measure provides useful supplemental information to management and investors regarding the performance of the Company’s business operations, facilitates a better comparison of results for current periods with the Company’s previous operating results, and assists management in analyzing future trends, making strategic and business decisions and establishing internal budgets and forecasts. A reconciliation of non-GAAP adjusted EBITDA to GAAP net loss in the most directly comparable GAAP measure, is provided in the below schedule.

There are limitations in using this non-GAAP financial measure because it is not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. This non-GAAP financial measure should not be considered in isolation or as a substitute for GAAP financial measures. Investors and potential investors should consider non-GAAP financial measures only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP and the reconciliations of the non-GAAP financial measure provided in the below schedules.

About the Essure® Procedure

The Essure procedure, FDA approved since 2002, is the first permanent birth control method that can be performed in the comfort of a physician’s office in less than 10 minutes (average hysteroscopic time) without hormones, cutting, burning or the risks associated with general anesthesia or tubal ligation. Soft, flexible inserts are placed in a woman’s fallopian tubes through the cervix without incisions. Over the next three months, the body forms a natural barrier around and through the micro-inserts to prevent sperm from reaching the egg. Three months after the Essure procedure, a doctor is able to perform an Essure Confirmation Test to confirm that the inserts are properly placed and the fallopian tubes are fully blocked, giving the patient reliance on Essure for permanent birth control.

The Essure procedure is 99.95% effective based on one year of follow up with zero pregnancies reported in clinical trials, making it the most effective form of permanent birth control on the market. The procedure is covered by most insurance plans, and when it is performed in a doctor’s office the cost to the patient may be as low as a simple co-pay. Essure has been proven and trusted by physicians since 2002, with more than 500,000 women worldwide having undergone the Essure procedure.
