• Revenues from Asia Pacific decreased 4% to $3.2 million for the fourth quarter, and increased 17% to $12.5 million for the year
• Operating income was $2.7 million for the fourth quarter and included technology licensing costs of $912,000, compared with operating income of $987,000 for the prior-year period; operating income for fiscal 2010 was $10.2 million compared with an operating loss of $9.7 million for fiscal 2009
• Cash and cash equivalents as of March 31, 2010 were $30.1 million, up $13.0 million from March 31, 2009 after repaying a line of credit of $2.5 million

Net income for the fourth quarter of fiscal 2010 was $2.3 million, or $0.13 per diluted share on 17.4 million weighted-average shares outstanding. This included $912,000 or $0.05 per diluted share in upfront payments related to the licensing of stent delivery technology and a new coil technology. Net income for the fourth quarter of 2010 included $1.2 million or $0.07 per diluted share of non-cash stock-based compensation expense. Net income for the fourth quarter of fiscal 2009 was $0.6 million, or $0.04 per diluted share on 16.1 million weighted-average shares outstanding, and included $1.3 million or $0.08 per diluted share of non-cash stock-based compensation expense.

"We are proud to report another quarter of record neurovascular revenues, up 24% compared with the prior year. Sales of neurovascular products increased 25% in the highly competitive U.S. market and increased 36% in Europe, which we attribute primarily to continued market share gains and consistent hemorrhagic procedural volume,” said John Kilcoyne, Chairman and CEO of Micrus Endovascular Corporation. "We executed well throughout fiscal 2010, introducing value-added new products, growing sales, managing expenses and achieving our first year of profitability. We also bolstered our cash by $15.5 million during the year.

"Products we introduced in the past 24 months represented 34% of fourth quarter revenues, with the greatest contribution coming from those based on our novel Delta Wind™ technology. Our bare platinum and Cerecyte^® DeltaPaq™ filling microcoils represented 19% of revenues, and bare platinum and Cerecyte DeltaPlush™ finishing microcoils, which were fully launched in mid January 2010, comprised 9% of quarterly revenues. We are also gaining momentum with our Ascent^® occlusion balloon catheters. Ascent marks our entry into a new product category with a differentiated product and is providing us with access to new accounts and incremental revenue opportunities,” he added.

"We are pleased to announce that Dr. Andy Molyneux, the principal investigator of the Cerecyte Coil Trial, has advised us that he intends to present interim data from the trial at the American Society of Neuroradiology in Boston on May 20, 2010. The Cerecyte Coil Trial is a 500 patient randomized study comparing results of coiling with our Cerecyte microcoils against Micrus bare platinum microcoils. Based on our preliminary discussions with Dr. Molyneux, we believe that he will present interim data demonstrating that, based on the core lab assessment of angiographic success, the Cerecyte and Micrus bare platinum groups are superior to those of the ISAT study and that the safety outcomes for Micrus Cerecyte and Micrus bare platinum coils are also superior to the coiling results reported in the ISAT study, as well as all other published randomized data. In addition, Dr. Molyneux has advised us that due to the strong performance of Micrus bare platinum coils, it is unlikely that the data will demonstrate a statistically significant difference in angiographic outcome between the two groups,” said Mr. Kilcoyne.

Fiscal Fourth Quarter Financial Results

For the fourth quarter of fiscal 2010, total neurovascular revenues were $25.6 million, up 24% from the comparable prior-year period. Gross margin for the fourth quarter of fiscal 2010 was 75%, up from 72% for the fourth quarter of fiscal 2009.

Research and development expenses for the fourth quarter of fiscal 2010 were $3.4 million, compared with $2.0 million for the comparable prior-year period.

Sales and marketing expenses for the fourth quarter of fiscal 2010 were $7.6 million, compared with $6.3 million for the fourth quarter of fiscal 2009. The increase was primarily due to increases in sales incentives resulting from higher sales, personnel expenses and product launch and meeting costs.

Other expense, net, was $525,000 for the fourth quarter of fiscal 2010, compared with $422,000 for the fourth quarter of fiscal 2009. These expenses were primarily due to losses resulting from the remeasurement of foreign currency transactions.

Forward-Looking Statements

Micrus, from time to time, may discuss forward-looking information, including estimated fiscal year 2011 revenues and profitability, the conclusions of our Cerecyte Coil Trial and the success of the Ascent occlusion balloon catheters. Except for the historical information contained in this release, all forward-looking statements are predictions by the Company’s management and are subject to various risks and uncertainties that may cause results to differ from management’s current expectations. Such factors include current worldwide economic conditions, continued growth in embolic coiling procedures and market acceptance of our products, challenges associated with complying with applicable state, federal and international regulations related to sales of medical devices, the results of any studies or clinical trials related to our products or those of our competitors, the Company’s limited operating history and history of significant operating losses, fluctuations in quarterly operating results, which are difficult to predict, the Company’s dependence on developing new products or product enhancements and other risks as detailed from time to time in risk factors and other disclosures in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2009, as well as in its other filings with the Securities and Exchange Commission. All forward-looking statements in this release represent the Company’s judgment as of the date of this release. The Company disclaims, however, any intention or obligation to update forward-looking statements.

To calculate operating segment revenue growth rates that exclude the impact of foreign exchange rates, the Company converts actual current period revenues from local currency to U.S. dollars using constant foreign exchange rates. The GAAP measure most comparable to this non-GAAP measure is growth rate percentages based on GAAP revenue. A reconciliation of this non-GAAP financial measure to the corresponding GAAP measure is included in the table above. The impact of foreign exchange rates is highly variable and difficult to predict. In addition, the Company provides constant dollar revenue changes for Europe revenues because management uses the measures to understand the underlying change in revenue excluding the impact of items that are not under management’s direct control, such as changes in foreign exchange rates.
