(the &#8220;Company&#8221;) has experienced disruption of procedures in countries whose healthcare systems are impacted by the COVID-19 outbreak, including China, Korea, Italy, and Taiwan. Some placements of new systems have also been delayed in these countries. As of the date of this Form 8-K, these early countries impacted by the COVID-19 outbreak do not represent a material portion of our current procedure volume. However, the growth in infections in Europe and the United States, which represent a larger portion of our procedure volume, combined with the recent guidance by the Surgeon General and American College of Surgeons advising the deferral of elective procedures in areas with a concentration of COVID-19 infections may further disrupt our business. As a result, we anticipate that the procedure volume and system placement disruption will expand as the COVID-19 outbreak intensifies globally.</span></div><div style="text-align:justify;margin-bottom:6pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">In addition, restrictions on our ability to travel and access to our customers, as well as temporary closures of our facilities or the facilities of our suppliers and their contract manufacturers could negatively impact our sales and operating results. The impact of the COVID-19 outbreak on local economies and the global stock markets could also lead to curtailed or delayed capital spending by hospitals. The total impact of these disruptions could have a material impact on our financial results. At this date, we cannot predict the specific extent, or duration, of the impact of the COVID-19 outbreak on our financial results. We will provide additional information during our next earnings call in April.</span></div><div style="text-align:justify;margin-bottom:6pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">Our long-term fundamentals remain strong, and our first priority&#8212;now and always&#8212;is the health and safety of patients, our employees, customers, providers, and the communities in which we operate.</span></div><div style="text-align:justify;margin-bottom:6pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%;">Forward-Looking Statement</span></div><div style="text-align:justify;margin-bottom:6pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">This Form 8-K contains forward-looking statements, including statements regarding the impact of the COVID-19 outbreak on the Company&#8217;s results of operations.
