Sirona (Nasdaq: SIRO), the dental technology leader, today announced its financial results for the quarter ended December 31, 2012. First Quarter Fiscal 2013 vs. First Quarter Fiscal 2012 Financial Results Revenue was $272.4 million, an increase of $14.3 million or up 5.5% (and up 8.6% on a constant currency basis). The Company's business segments performed as follows: CAD/CAM Systems increased 13.5% (up 16.5% on a constant currency basis), Treatment Centers increased 4.3% (up 8.4% on a constant currency basis), Imaging Systems increased 2.7% (up 4.9% on a constant currency basis), and Instruments decreased 5.8% (down 2.1% on a constant currency basis). Revenue in the United States increased 29.0%, while revenues outside the United States decreased 3.3% (up 0.6% constant currency). We had exceptional growth in the U.S. benefiting from strong demand for our Imaging and CAD/CAM products as well as from anticipated tax changes. Despite solid demand, sales in international markets were impacted by Omnicam capacity constraints and from the prioritization of the U.S., the challenging prior-year comparison for Imaging, and a back-end loaded order intake during the quarter, which will translate into sales in the second quarter of fiscal year 2013. Gross profit was $151.9 million, up $13.1 million. Gross profit margin was 55.8% in the first quarter of Fiscal 2013, compared to 53.8% in the prior year. Gross profit margin as a percent of sales was positively impacted by a positive segment and product mix and lower deal related amortization. Net income for the first quarter of 2013 was $38.3 million, or $0.68 per diluted share, versus $38.3 million, or $0.67 per diluted share in the prior year period. Non-GAAP adjusted earnings per diluted share for the first quarter of 2013 was $0.94 compared to $0.87 in the prior year quarter. A reconciliation of the non-GAAP measure to earnings per share calculated on a GAAP basis is provided in the attached table.
