Long Island City, New York, August 2, 2013 –Sirona (Nasdaq: SIRO), the dental technology leader, today announced its financial results for the quarter ended June 30, 2013.

Third Quarter Fiscal 2013 vs. Third Quarter Fiscal 2012 Financial Results

Revenue was $283.2 million, an increase of $41.2 million or up 17.0% (and up 15.7% on a constant currency basis). The Company’s business segments performed as follows: Imaging Systems increased 22.0% (up 21.0% on a constant currency basis), CAD/CAM Systems increased 20.4% (up 19.4% on a constant currency basis), Treatment Centers increased 10.2% (up 8.4% on a constant currency basis), and Instruments increased 4.5% (up 2.9% on a constant currency basis).

Revenue in the United States increased an exceptional 28.8%, and revenues outside the United States increased 11.8% (up 10.0% constant currency). U.S. revenues benefited from strong demand for our Imaging and CAD/CAM products, the delivery of Omnicom trade-ups, and the expanded agreement with Patterson. Sales growth in international markets was driven by an exceptionally strong performance in Germany, where we particularly benefited from orders following the International Dental Show (“IDS”).

Gross profit was $151.5 million, up $23.0 million. Gross profit margin was 53.5% in the third quarter of Fiscal 2013, compared to 53.1% in the prior year. Gross profit margin as a percent of sales was positively impacted by lower deal-related amortization, which more than offset margin compression mainly due to product mix.

Net income for the third quarter of 2013 was $40.6 million, or $0.72 per diluted share, versus $30.3 million, or $0.53 per diluted share in the prior year period. Non-GAAP adjusted earnings per diluted share for the third quarter of 2013 was $0.91 compared to $0.76 in the prior year quarter, or an increase of 19.2%. A reconciliation of the non-GAAP measure to earnings per share calculated on a GAAP basis is provided in the attached table.

* Non-GAAP adjusted EPS and constant currency growth and results are non-GAAP financial measures that exclude certain items. Please refer to “Reconciliation of GAAP and non-GAAP Information (unaudited)” in the attached exhibits for a description of these items.

At June 30, 2013, the Company had cash and cash equivalents of $205.7 million and total debt of $75.4 million, resulting in net cash of $130.3 million. This compares to net cash of $75.6 million at September 30, 2012.

Jeffrey Slovin, President and CEO of Sirona commented: “Sirona’s record third quarter reflects our strong showing at IDS, the delivery of Omnicam trade-ups and the continued adoption of digital dentistry. Both the U.S. and Germany had extraordinary quarters and were significant contributors to our robust results. Imaging and CAD/CAM led the way growing 21.0% and 19.4%, respectively, on a constant currency basis.”

Mr. Slovin continued: “We are on track for a third consecutive year of double digit revenue growth clearly demonstrating the strength of our organization. We continue to take market share and are well positioned for future growth.”

Fiscal 2013 Guidance

Management continues to anticipate FY13 constant currency revenue growth of 10% to 12%, and non-GAAP adjusted EPS^* in the range of $3.36 to $3.43.

First Nine Months Fiscal 2013 vs. First Nine Months Fiscal 2012 Financial Results

Revenue was $822.9 million, an increase of $90.9 million or up 12.4% (and up 12.9% on a constant currency basis). The Company’s business segments grew as follows: CAD/CAM Systems increased 18.4% (up 18.8% on a constant currency basis), Imaging Systems increased 11.7% (up 12.1% on a constant currency basis), Treatment Centers increased 10.5% (up 11.1% on a constant currency basis), and Instruments increased 0.3% (up 0.9% on a constant currency basis).

Revenue in the United States increased 23.7% benefiting from strong demand for our Imaging and CAD/CAM products, the anticipated implementation of the Medical Device Tax in 2013, the delivery of Omnicam trade-ups and the expanded agreement with Patterson. Revenues outside the United States increased 7.9% (up 8.5% constant currency) and were particularly driven by an exceptionally strong performance in Germany as well as robust growth in non-European international markets.

Gross profit was $448.1 million, up $56.2 million. Gross profit margin was 54.5% in the first nine months of Fiscal 2013, compared to 53.5% in the prior year. Gross profit margin as a percent of sales was positively impacted by lower levels of deal-related amortization.

Net income for the nine months ended June 30, 2013 was $ 110.5 million, or $1.96 per diluted share, versus $ 99.1 million, or $1.74 per diluted share in the prior year period. Non-GAAP adjusted earnings per diluted share was $ 2.60 in the first nine months of Fiscal 2013 compared to $ 2.30 in the first nine months of Fiscal 2012, or an increase of 12.8%.

** We are unable to provide estimates for these items because we are unable to predict the 2013 and long-term impact of foreign exchange due to unpredictability of future changes in foreign exchange rates.

To supplement our consolidated financial statements and our business outlook, we use the following non-GAAP financial measures: (i) non-GAAP adjusted net income, and (ii) non-GAAP adjusted earnings per diluted share, which exclude, as applicable, amortization and depreciation expense resulting from the step-up to fair values of intangible and tangible assets related to past business

combinations gain/loss on foreign currency transactions, gain/loss on derivative instruments and any related tax effects and to the extent relevant in a particular period, any other cash or non-cash items that management does not view as indicative of its ongoing operating performance. Also set forth above under the heading “FORWARD-LOOKING” are reconciliations of forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures.

Management recognizes that the use of these non-GAAP measures has limitations, including the fact that they might not be comparable with similar non-GAAP measures used by other companies and that management must exercise judgment in determining which types of charges and other items should be excluded from its non-GAAP financial measures. Management currently compensates for these limitations by providing full disclosure of each non-GAAP financial measure and a reconciliation to the most directly comparable GAAP measure. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

We use these non-GAAP financial measures for financial and operational decision making and as a means to evaluate period-to-period comparisons. Our management believes that these non-GAAP financial measures provide meaningful supplemental information regarding our “core operating performance”. Management believes that “core operating performance” represents Sirona’s operating performance in the ordinary, ongoing and customary course of its operations. Accordingly, management excludes from “core operating performance” the impact of acquisition-related intangible depreciation and amortization in order to compare our underlying financial performance to prior periods, certain charges related to currency revaluation of assets and liabilities that do not reflect our period-to-period core operating performance, and to the extent relevant in a particular period, any other cash or non-cash items that management does not view as indicative of its ongoing operating performance. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting and analyzing future periods. These non-GAAP financial measures also facilitate management’s internal evaluation of period-to-period comparisons. We believe these non-GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision making and (2) they are provided to and used by our institutional investors and the analyst community to facilitate comparisons with prior and subsequent reporting periods.

Constant Currency: We have included certain revenue information in this press release on a constant currency basis. This information is a non-GAAP financial measure. We additionally present revenue on a constant currency basis because we believe it facilitates a comparison of our operating results from period to period without regard to changes resulting solely from fluctuations in currency rates.

Sirona calculates constant currency revenue growth by comparing current period revenues to prior period revenues with both periods converted at the U.S. Dollar/Euro average foreign exchange rate for each month of the current period. The average exchange rates for the three and nine months ended June 30, 2013, were $1.30590 and $1.30786, respectively, and varied from $1.28296 to $1.33851. For the three and nine months ended June 30, 2012, average exchange rates converting Euro denominated revenues into U.S. Dollars of $1.28513 and $1.31527, respectively, were applied.

Our forecasted 2013 constant currency net revenue guidance excludes the impact of foreign exchange. We are unable to reconcile our projected 2013 constant currency net revenue growth to our full-year projected 2013 net revenue growth because we are unable to predict the 2013 and long-term impact of foreign exchange due to the unpredictability of future changes in foreign exchange rates. Therefore, we are unable to provide a reconciliation of these measures.
