Sirona Reports Fiscal 2015 First Quarter Results

Long Island City, New York, February 6, 2015 – Sirona (Nasdaq: SIRO), the dental technology leader, today announced its financial results for the quarter ended December 31, 2014.

First Quarter Fiscal 2015 vs. First Quarter Fiscal 2014 Financial Results

Revenue was $293.0 million, a decrease of $5.7 million or down 1.9% (up 3.8% on a local currency basis). The Company's business segments performed as follows: Imaging Systems increased 2.1% (up 5.5% on a local currency basis), Instruments increased 0.3% (up 9.2% on a local currency basis), Treatment Centers decreased 0.7% (up 8.5% on a local currency basis), and CAD/CAM Systems decreased 7.2% (down 2.1% on a local currency basis).

Revenue in the United States increased 1.6% benefitting from strength in Imaging while facing a difficult year-over-year comparison due to last year’s high deliveries of Omnicam trade-up units.

International revenues decreased 3.7% in U.S. dollars, but increased 4.9% in local currencies. The local currency growth was driven by the increasing success of our expanded international sales and services infrastructure, led by the Asia-Pacific region.

Gross profit was $162.9 million, up $0.2 million. Gross profit margin was 55.6% in the first quarter of Fiscal 2015, compared to 54.5% in the prior year. The increase in the gross profit margin was mainly due to the benefit of foreign exchange effects as well as reduced amortization and depreciation expense resulting from the step-up to fair values of tangible and intangible assets.

Net income attributable to Sirona Dental Systems, Inc. for the first quarter of 2015 was $46.0 million, or $0.82 per diluted share, versus $44.2 million, or $0.79 per diluted share in the prior year period. Non-GAAP adjusted earnings per diluted share for the first quarter of 2015 was $0.96, the same as 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.

At December 31, 2014, the Company had cash and cash equivalents of $368.1 million and total debt of $79.5 million, resulting in net cash of $288.6 million. This compares to net cash of $135.4 million at December 31, 2013.

Jeffrey Slovin, President and CEO of Sirona commented: “We are off to a good start for fiscal 2015 with 3.8% local currency growth driven by the Asia-Pacific region. The U.S. still grew 1.6%, despite a difficult comparison due to the very successful Omnicam trade-up program last year. On a segment level, both Instruments and Treatment Centers significantly outpaced the market with 9.2% and 8.5% local currency growth, respectively. CAD/CAM was down 2.1%, in local currency, despite robust new-user sales around the globe. This new user growth, although significant, could not keep pace with last year’s 12.3% local currency growth.”

Mr. Slovin continued: “The digital evolution of dentistry is spreading across the globe and Sirona is leading the way. As the unmatched leader in dental digital solutions, we are very excited about the introduction of numerous new products at the upcoming International Dental Show in March. Given the strong demand for our products, and an ever increasing interest in digital dentistry, we continue to expect a strong back-half of the fiscal year.”

Fiscal 2015 Guidance

Management reiterates guidance of FY15 local currency revenue growth of 6% to 8% and non-GAAP adjusted EPS^* in the range of $3.95 to $4.05 (reflecting growth of approximately 8% to 10%).

FORWARD-LOOKING

Non-GAAP Adjusted EPS Guidance (unaudited)

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, 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 Sirona’s operating performance in the ordinary, ongoing and customary course of its operations. Accordingly, management excludes 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.

Local Currency: Certain revenue information is presented on a local currency basis (“Local Currency”). This information is a non-GAAP financial measure. Sirona supplementally presents this revenue information because it believes doing so facilitates a comparison of its operating results from period to period without regard to changes resulting solely from fluctuations in currency rates.

Sirona calculates local currency revenue growth by comparing current-period revenues to prior-period revenues with both periods converted at the U.S. Dollar/local currency average foreign exchange rate for each month of the current period for the currencies in which we do business.

Our forecasted 2015 local currency net revenue growth guidance excludes the impact of exchange rate fluctuations due to the unpredictability of future changes in foreign exchange rates. Therefore, we do not provide a reconciliation of these measures.
