President and CEO Commentary

Randy Thurman, Chairman, President and Chief Executive Officer of CardioNet, commented: “2009 was an extraordinary year for CardioNet in many ways, headlined by the major accomplishment of a 50% increase in patient volume.  This clearly demonstrates physician acceptance of CardioNet’s MCOTTM technology, which is one of the first significant commercial applications in wireless medicine.  CardioNet’s leadership in wireless mobile cardiac outpatient telemetry is underscored by a majority of physicians choosing CardioNet over competing products.  Physician and patient feedback indicates this success is due to our comprehensive reporting capabilities, excellent customer service, and demonstrated diagnostic superiority, supported by 29 published abstracts and peer reviewed papers referencing CardioNet’s MCOTTM.  CardioNet remains the only company in the industry with this level of clinical data supporting the efficacy and acceptance of our technology.  We are also the only company whose device was shown to be superior to other monitoring technologies in a published clinical trial.

“MCOTTM’s high volume growth in 2009 was contrasted by the unexpected decision by Highmark Medicare Services to cut our reimbursement by one-third.  This reduction, as well as the decline in reimbursement by some commercial payors, impacted the Company’s ability to remain profitable.  In response, CardioNet has taken affirmative steps to return to operational profitability and ensure the continued availability of MCOTTM to the physicians and patients benefiting from the technology.  These initiatives aim to improve productivity and reduce costs while also working with CMS to obtain an appropriate national reimbursement rate.  In addition, CardioNet has nearly $50 million in cash and no debt, providing us with the flexibility to pursue all appropriate means to enhance stakeholder value, including evaluating strategic alternatives.

“Turning to 2010, our focus will be on continuing to grow volume and build market share, combined with expanding our efforts to reduce expenses in order to better adjust to the difficult reimbursement climate.  These cost reductions will in no way impact the unparalleled service that we provide to physicians and patients.  We also expect to enhance our service offering with the launch of our next generation MCOTTM device in 2010.  This cutting edge technology will allow us to advance MCOTTM into other areas of monitoring and positions us to enter international markets.  In addition, the cost of our next generation device is expected to be significantly lower, and we should benefit from this beginning in 2011.

“In 2009, the business experienced unexpected volatility primarily as a result of the reduced reimbursement.  In response, we have made steady progress on every front including national reimbursement, cost reductions and volume growth.  However, until we experience a period of stability and progress on our initiatives, and therefore gain more predictability, we will not provide specific revenue and earnings guidance.  We are providing outlook on 2010 volume growth and expense reduction targets.

“To summarize, we are optimistic about the future of CardioNet.  We have responded to the unexpected reimbursement challenges of 2009 by strengthening and streamlining our operations.  CardioNet and CMS are engaged in a constructive process which could lead to national reimbursement at an appropriate rate.  We have almost $50 million in cash and no debt which will enable us to invest in our future.  With our diagnostic superiority, our advanced and increasing reporting capabilities, and exceptional service, we expect to expand our leadership in mobile cardiac outpatient telemetry.”

Fourth Quarter Financial Results

Revenues for the fourth quarter of 2009 were $33.3 million compared to $34.4 million in the fourth quarter of 2008, a decrease of $1.1 million.  For the fourth quarter 2009, the Company’s payor mix was 34% Medicare and 66% commercial.  While the increased MCOTTM patient volume drove additional revenue, it was offset by the full quarter impact of the previously announced Medicare rate reduction as well as lower commercial reimbursement.  Gross profit declined to $20.3 million in the fourth quarter of 2009, or 60.9% of revenues, compared to $23.9 million in the fourth quarter of 2008, or 69.4% of revenues.

On a GAAP basis, operating loss was $15.5 million in the fourth quarter of 2009 compared to operating income of $6.4 million in the fourth quarter of 2008. Excluding $10.1 million of expense primarily related to the forfeiture of stock options, adjusted operating loss was $5.4 million in the fourth quarter of 2009. This compares to adjusted operating income of $6.5 million in the fourth quarter of 2008, which excludes $0.1 million of expense related to the integration of PDSHeart and other restructuring efforts in the prior year period.

On a GAAP basis, net loss for the fourth quarter of 2009 was $15.9 million, or a loss of $0.67 per diluted share, compared to net income of $6.9 million, or $0.29 per diluted share, for the fourth quarter of 2008.  Adjusted net loss for the fourth quarter of 2009 was $5.8 million, or a loss of $0.24 per diluted share, excluding expenses primarily related to the forfeiture of stock options. This compares to adjusted net income of $3.7 million, or $0.16 per diluted share, for the fourth quarter of 2008, which excludes the impact of integration, restructuring and other nonrecurring charges as well as NOL utilization.

Full Year 2009 Financial Results

Revenues for the twelve months ended December 31, 2009 increased to $140.6 million compared to $120.5 million in the comparable period in the prior year.  For the full year 2009, gross profit increased to $91.9 million, or 65.4% of revenues, compared to $80.5 million, or 66.9% of revenues, in the comparable period in the prior year.

On a GAAP basis, operating loss for the full year 2009 was $20.6 million compared to operating income of $9.7 million in the prior year.  Excluding $14.6 million of expense related to integration, restructuring and other nonrecurring charges, adjusted operating loss was $6.0 million for the full year 2009.  This compares to adjusted operating income of $14.6 million for the full year 2008, which excludes $4.9 million of integration, restructuring and other nonrecurring charges.

On a GAAP basis, net loss available to common shareholders, which is derived by reducing net income by the accrued dividends and accretion on mandatorily redeemable convertible preferred stock, was a loss of $20.5 million, or a loss of $0.86 per diluted share, for the twelve months ended December 31, 2009, compared to net income available to common shareholders of $6.6 million, or $0.29 per diluted share, for the same period last year.  The mandatorily redeemable convertible preferred stock, which was issued in part to finance the March 2007 PDS Heart acquisition, was converted to common stock in connection with CardioNet’s March 2008 initial public offering.

Adjusted net loss for the full year 2009 was $5.9 million excluding expenses related to integration, restructuring and other nonrecurring charges, or a loss of $0.25 per diluted share.  This compares to adjusted net income of $8.7 million, or $0.39 per diluted share, for the full year 2008, which excludes the impact of integration, restructuring, other nonrecurring charges, NOL utilization and dividend accretion.

Heather Getz, CardioNet’s Chief Financial Officer, commented: “In 2009, CardioNet’s MCOTTM volume grew by 50% and total revenue grew by nearly 17% over 2008. The positive impact of volume was offset by the significant reimbursement challenges faced by the Company during the year.  The reduced reimbursement also negatively affected our gross margin percentages which are down year over year despite the fact that our cost per patient has declined compared to 2008.

“In the fourth quarter, we gained positive momentum in our cash collections resulting in a 16-day reduction in our DSO over the third quarter.  This was driven by the process improvements that we implemented in the fourth quarter of 2009.  Our cash balance increased over $6 million compared to the third quarter 2009, bolstering our already strong balance sheet which will enable us to invest for the future.

“Due to the initiatives that have already been implemented, we enter 2010 with a lower cost structure.  We recently began execution of additional measures aimed at $15 million in cost reductions over the next 18 months.  As a result of these actions, we look forward to growing our business more efficiently and cost effectively.”
