AtriCure Announces Preliminary Results for Fourth Quarter and Full Year 2014
Issues 2015 Guidance
WEST CHESTER, Ohio January 12, 2015 AtriCure, Inc. (Nasdaq: ATRC), a leading innovator in surgical treatments for atrial fibrillation (Afib) and Left Atrial Appendage Management (LAAM), today announced preliminary financial results for fourth quarter and full year 2014 and issued 2015 financial guidance.
Preliminary and unaudited revenue for fourth quarter 2014 is expected to be approximately $29.5 million, reflecting growth of approximately 34.6% over the fourth quarter of 2013. Based on this preliminary estimate, revenue from U.S. customers is expected to be $22.1 million, reflecting growth of 35.1%, and revenue from international customers is expected to be $7.3 million, reflecting growth of 33.2%, or 41.4% on a constant currency basis.
Preliminary revenue for full year 2014 is expected to be $107.5 million, reflecting year over year growth of 31.3% over full year 2013.
We are pleased to report preliminary fourth quarter and full year 2014 results which reflect continued growth and momentum across our product lines. We continue to see a tremendous amount of untapped potential in our markets, and thus our plans remain focused on growth and successfully expanding the Afib market through improved patient outcomes, training and education. We are providing our outlook for 2015 and look forward to providing additional detail on our growth strategy when we release our final 2014 results in late February, said Mike Carrel, President and Chief Executive Officer of AtriCure.
2015 Financial Guidance
Management projects that 2015 revenue will be in the range of $122.5 million to $124.5 million, which represents an increase of 14% to 16% over 2014. At current foreign exchange rates, this range reflects an estimated $1.6 million adverse currency impact due to the weakening Euro against the U.S. Dollar.
Adjusted EBITDA, a non-GAAP measure, is projected to be a loss in the range of $7 to $9 million for 2015 as we continue to make strategic investments to drive our long-term growth plan. We will provide a reconciliation of this non-GAAP measure to the related GAAP measure in our release of final 2014 results.

Vision
AtriCure seeks to develop solutions
for and become a leader in the
treatment of Atrial Fibrillation (Afib)
and left atrial appendage (LAA)
management for stroke reduction |

Key Takeaway Messages
Atrial Fibrillation is a health problem of epidemic proportions
Only 27% of all surgical patients with AF are treated leaving a big opportunity for
treatment

Many current therapies such as anti-arrhythmic medications are
ineffective
The Cox-Maze IV procedure is very effective at treating Afib
Patients
with
Afib
on

4-6

Atrial Fibrillation Overview
Condition Overview
Continuum of Care
Abnormal electrical impulses cause the upper
chambers of the heart to quiver at rapid rates of 400
to 600 BPM
Frequently associated with cardiovascular disease,
in particular hypertension, congestive heart failure,
coronary artery disease, etc.
Effects
Causes blood in the atria to become static,
increasing the risk of blood clot formation, stroke,
and other serious complications
Symptoms include heart palpitations, dizziness,
fatigue and shortness of breath, and these
symptoms can be debilitating / life threatening
Types
Paroxysmal: rapid heart rate begins and stops
suddenly
lasting
24
hours
1
week
Persistent: abnormal heart rate continuing for more
than a week
Permanent: normal heart rhythm can't be restored;
often the result of paroxysmal and persistent Afib
becoming more frequent
Initial treatments include electrical cardioversion
(shock to return heart to normal rhythm) and
anticoagulant medicines such as warfarin
If persistent, anticoagulants are augmented by rate-
control medicines such as beta blockers
When drugs fail, MIS catheter ablation and open-
procedure surgical ablation are used to disrupt the
electric impulses that cause Afib |
