Bruker Corporation Reports

First Quarter 2013 Financial Results

BILLERICA, Mass. — May 2, 2013 — Bruker Corporation (NASDAQ: BRKR) today reported financial results for its first quarter ended March 31, 2013.

Revenues for the first quarter of 2013 declined by 3.0 percent to $393.4 million, compared to $405.6 million in Q1 2012.  Excluding a 1.5 percent negative effect from changes in foreign exchange rates and a 0.4 percent net negative effect from acquisitions and divestitures, Bruker’s revenues declined year-over-year by 1.1 percent in the first quarter of 2013.

Bruker reported first quarter 2013 GAAP operating income of $12.2 million, or 3.1% of revenues, compared to $34.4 million, or 8.5% of revenues in the first quarter 2012.  First quarter 2013 GAAP earnings per diluted share (EPS) were $0.03, compared to EPS of $0.09 in the first quarter of 2012.

On a non-GAAP basis, Bruker reported first quarter 2013 non-GAAP operating income of $23.6 million, or 6.0% of revenues, compared to $43.6 million, or 10.7% of revenues, in Q1 of 2012.  First quarter 2013 non-GAAP EPS were $0.08, compared to $0.14 in the first quarter of 2012.  A reconciliation of GAAP to non-GAAP financial measures is provided in the Company’s financial tables accompanying this press release.

“Our first quarter performance was adversely affected by changes in foreign exchange rates, weakness in the semiconductor and data storage industries, and temporary operational issues,” said Frank Laukien, President and CEO of Bruker.  “While we are disappointed with our slow start to the year, our first quarter bookings grew year-over-year, and we believe we can regain momentum in the remaining quarters of 2013.  As a result, excluding the effects of currency, our full year 2013 outlook for organic revenue growth remains unchanged.”

From a segment perspective, Bruker Scientific Instruments (BSI) reported an organic revenue decline of 1.0 percent in the first quarter of 2013, while Bruker’s Energy and Superconducting Technologies (BEST) segment reported organic revenue growth of 3.4 percent, both year-over-year.

“Our first quarter 2013 performance was adversely affected by changes in foreign exchange rates, particularly the steep drop in the Japanese Yen,” said Charles Wagner, Chief Financial Officer of Bruker.  “Our business in Japan represents approximately ten percent of our revenue, but only a small portion of our expenses.  Consequently, these rate changes not only lowered our revenue, but also disproportionately reduced our profitability in the first quarter.  We remain focused on delivering the savings from the productivity initiatives we announced previously.  During Q1, we accomplished two significant divestiture and outsourcing milestones related to these programs, and we continue to develop other opportunities to improve our operational efficiency.”

Bruker is updating its guidance for 2013 primarily as a result of weakness in the Japanese Yen.  The Company expects to see a reduction of reported revenue growth rates by approximately 2 percent due to the recent Yen depreciation.  This reduction is expected to result in reported revenue growth of 2 to 3 percent for the full year 2013.  Bruker now expects to report full year 2013 non-GAAP EPS of between $0.80 and $0.83, a reduction of $0.08 from previous guidance, also due primarily to the weaker Yen.

Use of Non-GAAP Financial Measures

The non-GAAP financial measures used for Bruker Corporation in this press release are non-GAAP gross profit; non-GAAP gross profit margin; non-GAAP operating income; non-GAAP operating margin; non-GAAP interest and other income (expense) net; non-GAAP profit before tax; non-GAAP tax rate; non-GAAP net income; non-GAAP earnings per share; and free cash flow.  These non-GAAP measures exclude costs related to restructuring costs, acquisition and related integration expenses, amortization of acquired intangible assets and other costs that are non-recurring in nature. There are limitations in using non-GAAP financial measures as they are not prepared in accordance with U.S. generally accepted accounting principles and may be different from non-GAAP financial measures used by other companies.

We believe that the non-GAAP financial measures provide useful and supplementary information to investors regarding our quarterly and annual performance.  It is our belief that these non-GAAP financial measures are particularly important as Bruker initiates restructuring activities to expand operating margins.  The financial impact of these activities, particularly restructuring activities, can be large and adversely affect the comparability of our results from period-to-period.  We define free cash flow as net cash provided by operating activities less additions to property, plant, and equipment.  We believe free cash flow is a useful measure to evaluate our business as it indicates the amount of cash generated after additions to property, plant, and equipment that is available for, among other things, strategic acquisitions, investments in our business, and repayment of debt.

We regularly use non-GAAP financial measures internally to understand, manage, and evaluate our business results and make operating decisions.  We also measure our employees and compensate them, in part, based on such non-GAAP measures.  For the same reasons, we also use this information for our forecasting activities.

Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.  The non-GAAP financial measures are meant to supplement, and to be viewed in conjunction with, GAAP financial measures.  They are limited in value because they exclude charges that have a material effect on our reported results and, therefore, should not be relied upon as the sole financial measures to evaluate our financial results.    Investors are encouraged to review the reconciliation of the financial measures to their most directly comparable GAAP financial measures as provided in the tables accompanying this press release.
